　しかしながら、ホルダ本体は他の医療器具と同様に樹脂から構成されるところ、上記特許文献１に記載の採血管ホルダでは、固定部が肉薄に構成されていることから固定部が変形（弾性変形および塑性変形）し易く、アダプタの固定が不安定となる場合があった。 However, while the holder main body is made of resin like other medical instruments, in the blood collection tube holder described in Patent Document 1, the fixed portion is configured to be thin, so that the fixed portion deforms (e.g., elastic deformation and deformation). plastic deformation), and the fixing of the adapter may become unstable.

　本発明は、このような実情に鑑み、採血管に接続されるアダプタを安定的に固定することが可能な採血管ホルダを提供しようとするものである。 In view of such circumstances, the present invention aims to provide a blood collection tube holder capable of stably fixing an adapter connected to a blood collection tube.

　本発明の採血管ホルダは、先端側に底部を有する有底筒状に構成され、採血管の少なくとも一部を収容するホルダ本体と、前記底部に設けられ、前記採血管に接続されるアダプタが挿入されて固定される筒状の固定部と、前記固定部の外周側に設けられる外壁部と、前記固定部と前記外壁部の間に配置される接続部と、を備えることを特徴とする。 The blood collection tube holder of the present invention is configured in a bottomed cylindrical shape having a bottom portion on the distal end side, and includes a holder main body that accommodates at least a portion of the blood collection tube, and an adapter that is provided on the bottom portion and is connected to the blood collection tube. It is characterized by comprising a cylindrical fixing portion that is inserted and fixed, an outer wall portion that is provided on the outer peripheral side of the fixing portion, and a connecting portion that is arranged between the fixing portion and the outer wall portion. .

　本発明の採血管ホルダによれば、外壁部によって固定部の変形を抑制することが可能となるため、採血管に接続されるアダプタを安定的に固定することができる。すなわち、接続部を介して外壁部により固定部を支持することが可能となるため、ホルダ本体へアダプタを固定する際、さらには固定後のアダプタに外力が加わったような場合にも固定部を変形し難くし、ホルダ本体にアダプタを安定的に固定することができる。 According to the blood collection tube holder of the present invention, deformation of the fixing part can be suppressed by the outer wall part, so that the adapter connected to the blood collection tube can be stably fixed. In other words, since the fixing part can be supported by the outer wall through the connecting part, the fixing part can be held even when the adapter is fixed to the holder main body, and even when an external force is applied to the fixed adapter. It is difficult to deform, and the adapter can be stably fixed to the holder body.

　また、本発明の採血管ホルダにおいて、前記接続部は、前記底部、前記固定部および前記外壁部の少なくともいずれか１つと一体的に設けられることが好ましい。 Further, in the blood collection tube holder of the present invention, it is preferable that the connecting portion is provided integrally with at least one of the bottom portion, the fixing portion and the outer wall portion.

　これによれば、接続部をホルダ本体と同時に形成することが可能となるため、接続部を低コスト且つ容易に構成し、固定部を外壁部によって確実に支持することができる。 According to this, it is possible to form the connection part at the same time as the holder main body, so that the connection part can be easily configured at low cost, and the fixed part can be reliably supported by the outer wall part.

　また、本発明の採血管ホルダにおいて、前記接続部は、前記固定部の周方向において断続的に設けられるが好ましい。 Further, in the blood collection tube holder of the present invention, it is preferable that the connecting portion is intermittently provided in the circumferential direction of the fixing portion.

　これによれば、接続部１５の周方向において占める範囲を調整することで、固定部１３の変形量を適宜に設定することが可能となるため、アダプタをより安定的に固定することができる。また、ホルダ本体と接続部を一体的に樹脂成形する場合にも、固定部およびその近傍を肉薄に構成することが可能となるため、ヒケやボイドといった成形不良を防止して固定部およびその近傍の形状精度を高め、アダプタをより安定的に固定することができる。 According to this, by adjusting the range occupied by the connecting portion 15 in the circumferential direction, it is possible to appropriately set the amount of deformation of the fixing portion 13, so that the adapter can be fixed more stably. In addition, even when the holder main body and the connecting portion are integrally resin-molded, the fixed portion and its vicinity can be made thin. The shape accuracy of the adapter can be improved, and the adapter can be fixed more stably.

　また、本発明の採血管ホルダにおいて、前記外壁部は、前記固定部を外周側から囲む筒状に構成されることが好ましい。 Further, in the blood collection tube holder of the present invention, it is preferable that the outer wall portion is configured in a cylindrical shape surrounding the fixing portion from the outer peripheral side.

　これによれば、外壁部の剛性を高めて固定部をより確実に支持することが可能となるため、アダプタをより安定的に固定することができる。 According to this, it is possible to increase the rigidity of the outer wall portion and support the fixed portion more reliably, so that the adapter can be fixed more stably.

　本発明によれば、採血管に接続されるアダプタを安定的に固定することが可能という優れた効果を奏し得る。 According to the present invention, it is possible to stably fix the adapter connected to the blood collection tube.

It communicates with the inside of the blood collection tube. That is, the blood sample collected from the blood collection needle tube flows into the blood collection tube and is stored therein. In general, the pressure inside the blood collection tube is reduced in advance, and the blood is sucked into the blood collection tube by the negative pressure.

　スリーブ１０３は、採血管とアダプタ１００を接続した状態では、採血管とハブ１０２の間で軸方向に圧縮された状態となるが、アダプタ１００から採血管を取り外すことで、接続用針管１０１を覆う元の形状に復帰するようになっている。 The sleeve 103 is axially compressed between the blood collection tube and the hub 102 when the blood collection tube and the adapter 100 are connected, but when the blood collection tube is removed from the adapter 100, the connecting needle tube 101 is covered. It will return to its original shape.

That is, the adapter 100 is fixed to the holder body 10 by inserting the hub 102 into the fixing portion 13 and engaging the male screw 102a and the female screw 13b.

　なお、雄ネジ１０２ａおよび雌ネジ１３ｂは、２条ネジから構成されている。また、本実施形態では、雌ネジ１３ｂを軸方向から見て互いに重ならない範囲に設けられた２つのネジ山から構成することで、ホルダ本体１０の金型構成を簡素化することを可能としている。 In addition, the male thread 102a and the female thread 13b are composed of double threads. In addition, in the present embodiment, the female screw 13b is composed of two threads provided in a range that does not overlap with each other when viewed in the axial direction, thereby simplifying the mold configuration of the holder body 10. .

　固定部１３の先端面１３ｃは、フランジ部１０２ｂと当接してアダプタ１００をホルダ本体１０に対して位置決めする部分となっている。また、ハブ１０２の固定部１３の内周面１３ａの先端側には、アダプタ１００の挿入を容易化すべく、先端側に向けて内径が漸次拡大するテーパ部１３ｄが設けられている。 The distal end face 13c of the fixing portion 13 is a portion that abuts against the flange portion 102b to position the adapter 100 with respect to the holder main body 10. A tapered portion 13d whose inner diameter gradually increases toward the distal end is provided on the distal end of the inner peripheral surface 13a of the fixed portion 13 of the hub 102 so that the adapter 100 can be easily inserted.

　外壁部１４は、固定部１３を外周側から囲むように設けられると共に、内径が固定部１３の外径よりも大きく設定されている。従って、外壁部１４の内周面１４ａと固定部１３の外周面１３ｅの間には、径方向において所定の間隔が設けられている。また、外壁部１４の内径は、ハブ１０２のフランジ部１０２ｂの外径よりもやや大きく設定されており、外壁部１４の軸方向寸法は、固定部１３よりも大きく設定されている。従って、アダプタ１００がホルダ本体１０に固定された状態では、フランジ部１０２ｂは外壁部１４内に収容されるようになっている。 The outer wall portion 14 is provided so as to surround the fixed portion 13 from the outer peripheral side, and the inner diameter is set larger than the outer diameter of the fixed portion 13 . Therefore, a predetermined radial distance is provided between the inner peripheral surface 14a of the outer wall portion 14 and the outer peripheral surface 13e of the fixing portion 13 . The inner diameter of the outer wall portion 14 is set slightly larger than the outer diameter of the flange portion 102 b of the hub 102 , and the axial dimension of the outer wall portion 14 is set larger than that of the fixed portion 13 . Therefore, when the adapter 100 is fixed to the holder main body 10, the flange portion 102b is accommodated within the outer wall portion 14. As shown in FIG.

　本実施形態では、ホルダ本体１０とアダプタ１００の間に通気性を持たせているため、外壁部１４を設けることで、固定部１３への手指やコネクタ等の接触を防止し、固定部１３およびアダプタ１００を破損や汚染等から保護するようにしている。すなわち、固定部１３とアダプタ１００の間の段差や通気用の隙間に何かが引っ掛かる等して固定部１３やアダプタ１００を破損させたり、汚染物が固定部１３とアダプタ１００の隙間に進入して
接続用針管１０１や採血管等に付着したりするのを防止している。 In this embodiment, since air permeability is provided between the holder main body 10 and the adapter 100, by providing the outer wall portion 14, the fixing portion 13 can be prevented from being touched by fingers, connectors, or the like. The adapter 100 is protected from damage, contamination, and the like. That is, if something gets caught in the step between the fixed part 13 and the adapter 100 or in the gap for ventilation, the fixed part 13 or the adapter 100 may be damaged, or contaminants may enter the gap between the fixed part 13 and the adapter 100 . This prevents the adhesive from adhering to the connecting needle tube 101, the blood collection tube, or the like.

　また、図示は省略するが、外壁部１４を設けることで、オスコネクタ１０２ｃ（または、アダプタ１００の備える採血用針管）の保護用のキャップを、ハブ１０２ではなく外壁部１４に固定することができるため、オスコネクタ１０２ｃの破損や汚染等からの保護をより確実にすることが可能となる。また、キャップを外壁部１４に固定することで、ホルダ本体１０とアダプタ１００の間の隙間を塞ぐことができるため、接続用針管１０１やスリーブ１０３等の汚染をより確実に防止することができる。 Also, although not shown, by providing the outer wall portion 14, the cap for protection of the male connector 102c (or the blood sampling needle tube included in the adapter 100) can be fixed to the outer wall portion 14 instead of the hub 102. Therefore, it is possible to more reliably protect the male connector 102c from damage, contamination, and the like. Further, by fixing the cap to the outer wall portion 14, the gap between the holder main body 10 and the adapter 100 can be closed, so that the contamination of the connecting needle tube 101, the sleeve 103 and the like can be prevented more reliably.

　接続部１５は、固定部１３と外壁部１４の間で両者を接続するように配置されている。本実施形態では、固定部１３および外壁部１４と一体的に形成されるリブ状の４つの接続部１５を、周方向において略等間隔（すなわち、約９０°間隔）で配列している。また、本実施形態の接続部１５は、底部１１の先端面１１ｂから先端側に向けて固定部１３および外壁部１４の（すなわち、ホルダ本体１０の）軸方向に延出するように設けられており、底部１１とも一体的に形成されている。 The connection part 15 is arranged between the fixing part 13 and the outer wall part 14 so as to connect them. In this embodiment, the four rib-like connecting portions 15 integrally formed with the fixing portion 13 and the outer wall portion 14 are arranged at approximately equal intervals (that is, approximately 90° intervals) in the circumferential direction. Further, the connecting portion 15 of the present embodiment is provided so as to extend in the axial direction of the fixing portion 13 and the outer wall portion 14 (that is, of the holder main body 10) from the distal end surface 11b of the bottom portion 11 toward the distal end side. , and is integrally formed with the bottom portion 11 .

　本実施形態では、この接続部１５を介して固定部１３を外壁部１４によって支持することを可能とし、これにより固定部１３の変形（弾性変形および塑性変形）を抑制するようにしている。すなわち、剛性の高い円筒状の外壁部１４によって固定部１３を外周側から支持することで、固定部１３の内外径が拡大するような変形、および固定部１３がホルダ本体１０の軸心に対して傾くような変形を抑制している。 In this embodiment, the fixing part 13 can be supported by the outer wall part 14 via the connection part 15, thereby suppressing deformation (elastic deformation and plastic deformation) of the fixing part 13. That is, by supporting the fixing portion 13 from the outer peripheral side by the cylindrical outer wall portion 14 with high rigidity, the fixing portion 13 is deformed such that the inner and outer diameters of the fixing portion 13 are expanded, and the fixing portion 13 is deformed relative to the axis of the holder body 10. It suppresses deformation such as tilting.

　このようにすることで、アダプタ１００をホルダ本体１０に安定的に固定することが可能となる。具体的には、固定部１３の変形を抑制することで、例えばホルダ本体１０に対してアダプタ１００が斜めに無理やりねじ込まれるといった事態を防止することが可能となる。すなわち、アダプタ１００をホルダ本体１０に対して適切な姿勢で固定することができるため、ホルダ本体１０内に挿入した採血管に対して接続用針管１０１を適切に穿刺し、適切に接続することが可能となる。 By doing so, it is possible to stably fix the adapter 100 to the holder body 10 . Specifically, by suppressing the deformation of the fixing portion 13, it is possible to prevent a situation in which the adapter 100 is forcibly screwed obliquely into the holder main body 10, for example. That is, since the adapter 100 can be fixed to the holder main body 10 in an appropriate posture, the blood collection tube inserted into the holder main body 10 can be appropriately punctured by the connecting needle tube 101 and connected properly. It becomes possible.

　さらに、例えば採血管への接続用針管１０１の穿刺時や、オスコネクタ１０２ｃに接続された採血用針管の生体への穿刺時に、アダプタ１００をホルダ本体１０に対して傾かせるような外力が加わった場合にも、アダプタ１００の傾きを抑制することが可能となる。 Furthermore, for example, when the connecting needle tube 101 is punctured into the blood collection tube or when the blood collection needle tube connected to the male connector 102c is punctured into the living body, an external force is applied to tilt the adapter 100 with respect to the holder body 10. Even in this case, it is possible to suppress the inclination of the adapter 100 .

　また、例えば雄ネジ１０２ａおよび雌ネジ１３ｂを適宜に弾性変形するように接触させて摩擦力による緩み止め効果を奏させる場合にも、固定部１３における弾性変形の復元力を増大させて緩み止め効果を確実に奏させることが可能となる。すなわち、雄ネジ１０２ａと雌ネジ１３ｂの羅合の緩みに起因するアダプタ１００のぐらつきや脱落を防止することができる。 Further, for example, when the male thread 102a and the female thread 13b are brought into contact with each other so as to be elastically deformed appropriately to exhibit the locking effect by the frictional force, the restoring force of the elastic deformation in the fixing portion 13 is increased to achieve the locking effect. can be played reliably. That is, it is possible to prevent the adapter 100 from wobbling or coming off due to loosening of the engagement between the male screw 102a and the female screw 13b.

　このように本実施形態では、固定部１３と外壁部１４の間に接続部１５を配置して、固定部１３の変形を抑制することで、アダプタ１００をホルダ本体１０に安定的に固定し、これにより、採血管ホルダ１の使用時に生じ得る不具合を未然に防止している。そして、この結果、採血管ホルダ１を安全に使用することを可能としている。 As described above, in the present embodiment, the connecting portion 15 is arranged between the fixing portion 13 and the outer wall portion 14 to suppress deformation of the fixing portion 13, thereby stably fixing the adapter 100 to the holder main body 10. This prevents problems that may occur when the blood collection tube holder 1 is used. As a result, the blood collection tube holder 1 can be used safely.

　また、本実施形態では、接続部１５を固定部１３、外壁部１４および底部１１と一体的に設ける（一体的に樹脂成形する）ことで、固定部１３を確実に支持するだけでなく、接続部１５の低コスト且つ容易な配置を可能としている。 In addition, in the present embodiment, the connecting portion 15 is provided integrally with the fixing portion 13, the outer wall portion 14, and the bottom portion 11 (integrally resin-molded). Low-cost and easy placement of the portion 15 is made possible.

　さらに、本実施形態では、接続部１５を周方向において断続的に設けることで、接続部１５を設けながらも固定部１３近傍が肉厚となるのを防止している。これにより、本実施
形態では、樹脂成形時に肉厚部分に生じ得るヒケやボイドといった成形不良を防止し、固定部１３および雌ネジ１３ｂの形状精度を向上させることができるため、アダプタ１００をホルダ本体１０により安定的に固定することが可能となっている。 Furthermore, in the present embodiment, by intermittently providing the connection portions 15 in the circumferential direction, it is possible to prevent the vicinity of the fixed portion 13 from becoming thick while the connection portions 15 are provided. As a result, in the present embodiment, it is possible to prevent molding defects such as sink marks and voids that may occur in thick-walled portions during resin molding, and to improve the shape accuracy of the fixing portion 13 and the female screw 13b. 10 enables stable fixation.

　また、接続部１５を周方向において断続的に設けることで、接続部１５の周方向において占める範囲を調整し、固定部１３の変形量を適宜に設定することが可能となる。これにより、本実施形態では、アダプタ１００の固定をより安定化させるだけでなく、雌ネジ１３ｂに緩み止め効果を奏させる場合にも、雄ネジ１０２ａとの羅合が過度に固くならないようにすることが可能となっている。 Further, by intermittently providing the connecting portions 15 in the circumferential direction, it is possible to adjust the range occupied by the connecting portions 15 in the circumferential direction and appropriately set the amount of deformation of the fixing portion 13 . As a result, in this embodiment, not only is the fixing of the adapter 100 more stable, but also when the female screw 13b has a locking effect, the engagement with the male screw 102a is prevented from becoming excessively hard. It is possible.

　なお、本実施形態では、接続部１５の軸方向長さを固定部１３の軸方向長さの約７３％に設定しているが、接続部１５の軸方向長さはこれに限定されるものではなく、例えば固定部１３の軸方向長さよりも長くしてもよい。接続部１５の軸方向長さを調整することによっても、固定部１３の変形量を適宜に設定することができる。 In this embodiment, the axial length of the connecting portion 15 is set to about 73% of the axial length of the fixing portion 13, but the axial length of the connecting portion 15 is limited to this. Instead, for example, it may be longer than the axial length of the fixed portion 13 . The amount of deformation of the fixing portion 13 can also be appropriately set by adjusting the axial length of the connecting portion 15 .

　次に、採血管ホルダ１の変形例について説明する。図４Ａ～Ｃならびに図５ＡおよびＢは、採血管ホルダ１の変形例を示した図であり、固定部１３、外壁部１４および接続部１５の周辺を部分的に示した図３ＡのＩＩ－ＩＩ線断面図である。 Next, a modified example of the blood collection tube holder 1 will be described. FIGS. 4A-C and FIGS. 5A and B are diagrams showing modifications of the blood collection tube holder 1, and partially showing the periphery of the fixing part 13, the outer wall part 14 and the connecting part 15, which is the same as the figure II-II of FIG. 3A. It is a line sectional view.

　図４Ａは、接続部１５を外壁部１４および底部１１のみと一体的に設けた場合の例を示しており、図４Ｂは、接続部１５を固定部１３および底部１１のみと一体的に設けた場合の例を示しており、図４Ｃは、接続部１５を底部１１のみと一体的に設けた場合の例を示している。 4A shows an example in which the connecting portion 15 is provided integrally with only the outer wall portion 14 and the bottom portion 11, and FIG. 4B shows an example in which the connecting portion 15 is provided integrally with only the fixing portion 13 and the bottom portion 11. FIG. 4C shows an example in which the connection portion 15 is provided integrally with only the bottom portion 11. FIG.

　このように、接続部１５と固定部１３の間、および接続部１５と外壁部１４の間のいずれか一方または両方に隙間を設けることで、固定部１３がある程度変形して接続部１５と外壁部１４または固定部１３が接触した後に、固定部１３が外壁部１４によって支持されるようにすることが可能となる。 In this way, by providing a gap between one or both of the connection portion 15 and the fixed portion 13 and between the connection portion 15 and the outer wall portion 14, the fixed portion 13 is deformed to some extent and the connection portion 15 and the outer wall portion are separated from each other. It is possible for the fixing part 13 to be supported by the outer wall part 14 after the part 14 or the fixing part 13 come into contact.

　すなわち、固定部１３の自由な変形を所定の程度だけ許容することができるため、アダプタ１００および固定部１３の互いに係合する部分（ここでは、雄ネジ１０２ａおよび雌ネジ１３ｂ）の構成によってはアダプタ１００のホルダ本体１０への固定をより容易化、またはより安定化することが可能となる。また、ホルダ本体１０またはアダプタ１００の構成によっては、固定部１３の撓みを所定の程度だけ許容することで、採血管ホルダ１を使い易くすることができる。 That is, since the fixing portion 13 can be allowed to freely deform to a predetermined degree, the adapter 100 and the fixing portion 13 can be deformed depending on the configuration of the mutually engaging portions (here, the male thread 102a and the female thread 13b). Fixing of 100 to holder main body 10 can be made easier or more stable. Depending on the configuration of the holder main body 10 or the adapter 100, the blood collection tube holder 1 can be made easier to use by allowing the fixing portion 13 to bend to a predetermined degree.

　なお、図示は省略するが、図４ＡおよびＢに示される例において接続部１５と底部１１の間に隙間を設けるようにしてもよい。すなわち、接続部１５は、外壁部１４のみと一体的に設けられるもの、または固定部１３のみと一体的に設けられるものであってもよい。また、図３ＡおよびＢに示される例において、接続部１５と底部１１の間に隙間を設けるようにしてもよい。すなわち、接続部１５は、固定部１３および外壁部１４のみと一体的に設けられるものであってもよい。 Although illustration is omitted, a gap may be provided between the connecting portion 15 and the bottom portion 11 in the example shown in FIGS. 4A and 4B. That is, the connecting portion 15 may be provided integrally with only the outer wall portion 14 or may be provided integrally with only the fixing portion 13 . Also, in the example shown in FIGS. 3A and 3B, a gap may be provided between the connection portion 15 and the bottom portion 11. FIG. That is, the connecting portion 15 may be provided integrally with only the fixing portion 13 and the outer wall portion 14 .

　接続部１５は、固定部１３、外壁部１４または底部１１の少なくともいずれか１つと一体的に設けられるものであれば、ホルダ本体１０の樹脂成形時に形成することができるため、接続部１５を低コスト且つ容易に設けることが可能となる。 As long as the connecting portion 15 is provided integrally with at least one of the fixing portion 13, the outer wall portion 14, and the bottom portion 11, the connecting portion 15 can be formed at the time of resin molding of the holder main body 10. It can be provided easily and at low cost.

　また、接続部１５の個数は、特に限定されず、任意の個数を採用することができる。また、接続部１５の形状は、特に限定されず、例えば周方向において連続的に設けられるものであってもよいし、軸方向において断続的に設けられるものであってもよい。また、接
続部１５は、不等間隔で配列されるものであってもよいし、例えば千鳥状に配列されるものであってもよい。また、図３ＡおよびＢ、ならびに図４Ａ～Ｃに示される接続部１５を適宜に組み合わせて設けるようにしてもよい。すなわち、接続部１５の個数、形状および配置は、特に限定されるものではなく、任意の個数、形状および配置を採用することができる。 Also, the number of connecting portions 15 is not particularly limited, and any number can be adopted. Moreover, the shape of the connecting portion 15 is not particularly limited, and for example, it may be provided continuously in the circumferential direction, or may be provided intermittently in the axial direction. Moreover, the connecting portions 15 may be arranged at irregular intervals, or may be arranged in a zigzag pattern, for example. Also, the connections 15 shown in FIGS. 3A and 3B and FIGS. 4A to 4C may be combined as appropriate. In other words, the number, shape, and arrangement of the connecting portions 15 are not particularly limited, and any number, shape, and arrangement can be adopted.

　図５ＡおよびＢは、接続部１５をホルダ本体１０とは別体的に構成した場合の例を示している。この例では、接続部１５を円筒状の部材から構成し、固定部１３と外壁部１４の間に先端側から圧入することで、接続部１５をホルダ本体１０に固定するようにしている。 FIGS. 5A and 5B show an example in which the connecting portion 15 is configured separately from the holder main body 10. FIG. In this example, the connecting portion 15 is made of a cylindrical member, and is press-fitted between the fixing portion 13 and the outer wall portion 14 from the tip side, thereby fixing the connecting portion 15 to the holder main body 10 .

　この場合、採血管ホルダ１の製造において、接続部１５の取付工程を別途設ける必要が生じるものの、固定部１３および外壁部１４をシンプルな形状とすることができるため、ホルダ本体１０の金型を簡素化し、コストを低減することが可能となる。 In this case, in manufacturing the blood collection tube holder 1, although it is necessary to provide a separate step of attaching the connecting portion 15, the fixing portion 13 and the outer wall portion 14 can be formed in a simple shape. It is possible to simplify and reduce costs.

　なお、接続部１５のホルダ本体１０への固定は、例えば係合、超音波溶着または接着剤による接着等、その他の手法によるものであってもよい。また、接続部１５の形状は、特に限定されず、例えば角筒状や螺旋状等であってもよいし、外周面や内周面に突起等を備えるものであってもよい。 It should be noted that the connection portion 15 may be fixed to the holder body 10 by other methods such as engagement, ultrasonic welding, or adhesion using an adhesive. Moreover, the shape of the connection portion 15 is not particularly limited, and may be, for example, a rectangular tubular shape, a spiral shape, or the like, or may be provided with projections or the like on the outer peripheral surface or the inner peripheral surface.

　また、接続部１５の材質は、特に限定されず、ホルダ本体１０と同一の樹脂であってもよいし、ホルダ本体１０とは異なる樹脂や金属等であってもよい。また、固定部１３と外壁部１４の間に接着剤や紫外線硬化樹脂等を流し込んで硬化させることで接続部１５を構成するようにしてもよい。 Further, the material of the connecting portion 15 is not particularly limited, and may be the same resin as the holder main body 10, or may be a different resin, metal, or the like from the holder main body 10. Alternatively, the connecting portion 15 may be configured by pouring an adhesive, an ultraviolet curing resin, or the like between the fixing portion 13 and the outer wall portion 14 and curing the resin.

　また、図５ＡおよびＢに示される例では、接続部１５と底部１１の間に隙間を設ける場合を示しているが、接続部１５と固定部１３の間、または接続部１５と外壁部１４の間に隙間を設けるようにしてもよいし、接続部１５と底部１１、固定部１３および外壁部１４の間に隙間が全く生じないようにしてもよい。 5A and 5B show a case where a gap is provided between the connection portion 15 and the bottom portion 11, but a gap is provided between the connection portion 15 and the fixed portion 13 or between the connection portion 15 and the outer wall portion 14. A gap may be provided between them, or no gaps may be formed between the connecting portion 15 and the bottom portion 11, the fixing portion 13 and the outer wall portion 14 at all.

　また、接続部１５は、アダプタ１００が備えるものであってもよい。すなわち、接続部１５は、ホルダ本体１０へアダプタ１００を固定する際に、固定部１３と外壁部１４の間に配置されるものであってもよい。なお、この場合、接続部１５は、ハブ１０２等と一体的に設けられるものであってもよいし、別体的に設けられるものであってもよい。また、ホルダ本体１０とは別体的に構成された接続部１５と一体的に設けられた接続部１５と組み合わせて設けるようにしてもよい。 Also, the connecting portion 15 may be provided in the adapter 100 . That is, the connecting portion 15 may be arranged between the fixing portion 13 and the outer wall portion 14 when the adapter 100 is fixed to the holder main body 10 . In this case, the connecting portion 15 may be provided integrally with the hub 102 or the like, or may be provided separately. Alternatively, the connecting portion 15 formed separately from the holder main body 10 may be combined with the connecting portion 15 formed integrally with the connecting portion 15 .

　その他、図示は省略するが、固定部１３および外壁部１４は、例えば楕円筒状や角筒状等、円筒状以外の形状に構成されるものであってもよい。また、固定部１３および外壁部１４は、底部１１から後端側に向けて突出するように設けられるものであってもよいし、先端側および後端側の両方に向けて突出するように設けられるものであってもよい。また、固定部１３および外壁部１４は、切り欠き部や窓部等を有するものであってもよい。 In addition, although illustration is omitted, the fixed portion 13 and the outer wall portion 14 may be configured in a shape other than a cylindrical shape, such as an elliptical cylindrical shape or a rectangular cylindrical shape. Further, the fixed portion 13 and the outer wall portion 14 may be provided so as to protrude from the bottom portion 11 toward the rear end side, or may be provided so as to protrude toward both the front end side and the rear end side. It may be something that can be obtained. Moreover, the fixed portion 13 and the outer wall portion 14 may have a notch portion, a window portion, or the like.

　また、外壁部１４は、筒状のものに限定されず、周方向において断続的に設けられるものであってもよい。また、フランジ部１０２ｂに係止する突起等を外壁部１４に設け、アダプタ１００の固定をさらに安定化させるようにしてもよい。また、固定部１３へのアダプタ１００の固定は、雄ネジ１０２ａおよび雌ネジ１３ｂの羅合によるものに限定されず、その他の係合構造によるものであってもよい。 Further, the outer wall portion 14 is not limited to a cylindrical shape, and may be intermittently provided in the circumferential direction. Further, the outer wall portion 14 may be provided with a protrusion or the like that engages with the flange portion 102b to further stabilize the fixation of the adapter 100. FIG. Moreover, the fixing of the adapter 100 to the fixing portion 13 is not limited to the engagement of the male screw 102a and the female screw 13b, and may be of another engagement structure.
