ただし、本発明は、この例に限らず、線状体60の一端側60aが吸盤部12に対して直に固定されていてもよいし、線状体60の一端側60aが可撓性チューブ11の遠位端11aに対して直に固定されていてもよい。
このように、可撓性チューブ11の遠位端11a又は吸盤部12に線状体60の一端側60aが固定されている。
吸盤部12の開口部12aは、吸盤部12の内部空間と連結部材13の内部空間とを介して、可撓性チューブ11の内部空間と連通している。
線状体側コネクタ70は、線状体60の他端側60b側に設けられている。この線状体側コネクタ70は、雌コネクタ50に対して着脱可能に連結可能である(図8参照)。
すなわち、処置具用部品10は(したがって冠状動脈バイパス術用処置具100は)、可撓性チューブ11の遠位端11a又は吸盤部12に一端側60aが固定されている線状体60を備え、線状体60の他端側60bに線状体側コネクタ70が設けられており、線状体側コネクタ70は、雄コネクタ40と雌コネクタ50とのうち、可撓性チューブ11の近位端11bに設けられている方のコネクタである可撓性チューブ側コネクタ(雌コネクタ50)に対して着脱可能に連結可能である。
線状体側コネクタ70は、当該線状体側コネクタ70の一端側に配置されていて可撓性チューブ側コネクタ(雌コネクタ50)と接続される連結部72と、当該線状体側コネクタ70の他端側に配置されている先細形状の突起部73と、を有する。
このように、可撓性チューブ側コネクタは、雌コネクタ50であり、線状体側コネクタ70は、雌コネクタ50と連結可能な第2雄コネクタであり、線状体側コネクタ70は、本体部71と、本体部71から突出して形成されていて雌コネクタ50に挿入される突部である連結部72と、を有する。
本体部構成部751は、本体部71を構成する筒状の部分である。
本体部構成部751は、一端側が開口していて、他端側(突起部73側)が閉塞している。
本体部構成部751には、線状体60の他端側60bが固定されている固定孔751aと、第2部材76が嵌入固定されている嵌入孔751bと、が形成されている。
固定孔751aと嵌入孔751bとは相互に隣接して配置されているとともに、相互に連通している。
固定孔751aと嵌入孔751bとのうち、嵌入孔751bが本体部構成部751の開口側に配置されている。
本体部構成部751において嵌入孔751bが形成されている部分の外周壁には、切欠形状部751cが形成されている。
嵌入部761には、凹部761aが形成されている。
凹部761aは、固定孔751aと連通しているとともに、切欠形状部751cと連通している。
他端側60bが固定孔751aに固定された線状体60は、凹部761aの内部と、切欠形状部751cとを介して、線状体側コネクタ70の周面70aから導出されている(引き出されている)。
連結部72は、嵌入部761から一方に突出している。
連結部72の外周面には、係合凸部72aが形成されている。
大径部77における小径部78側とは反対側の端部に嵌入部761が設けられている。
大径部77の外周面に係合凸部72aが形成されている。
雌コネクタ50は、当該雌コネクタ50の全体が管状に形成されている。すなわち、雌コネクタ50の一端から他端に亘って貫通孔50a(図4(c))が形成されている。
雌コネクタ50の軸方向(貫通孔50aの軸方向)における雌コネクタ50の一部分は、収容部52を構成しており、残りの部分は、差込管部59を構成している。
収容部52の内周面54には、螺旋状の係合凹部56(螺旋溝)が形成されている。
収容部52の係合凹部56と連結部72の係合凸部72aとが螺合することによって、雌コネクタ50と線状体側コネクタ70とが着脱可能に連結されるようになっている。
ただし、本発明は、この例に限らず、連結部72の外周面に係合凹部56が形成されている一方で、収容部52の内周面54に係合凸部72aが形成されていて、これら係合凹部56と係合凸部72aとが螺合されることで雌コネクタ50と線状体側コネクタ70とが連結されるようになっていてもよい。
また、収容部52の外周面における収容部52の一端52aの近傍には、第2係合凸部58が形成されている。
また、上述のように、ジョイント部20の吸引路21の遠位端21aには雄コネクタ40が設けられている。
雄コネクタ40の雄ルアー43(図5)は、収容部52と嵌合する形状に形成されている。雄コネクタ40の筒部44の内周面に形成された螺合部45は、収容部52の第2係合凸部58と螺合するようになっている。すなわち、雄コネクタ40は、雌ルアー(収容部52)と嵌合する雄ルアー43と、雄ルアー43の周囲に設けられている筒部44と、筒部44の内周面に形成されていて収容部52の第2係合凸部58と螺合する螺合部45と、を備える雄ルアーロック構造46を有する。
大径部521と小径部522とは、互いに同軸に配置され、且つ、軸方向において相互に連接されている。
そして、第2係合凸部58は、大径部521の外周面に形成されている。
差込管部59の外周面は、例えば、小径部522の外周面よりも更に小径に形成されている。
また、雌コネクタ50の収容部52の外周面において第2係合凸部58が形成されている位置は、図7、図8及び図10に示す例のように、一端52aから離間していても良いし、図4(a)、図4(b)、図4(c)、図5及び図6に示す例のように、一端52aと隣接していても良い。いずれにしても、雌コネクタ50は、雄コネクタ40と線状体側コネクタ70とのいずれに対しても連結可能に形成されている。
すなわち、図6に示すように、雄ルアー43を収容部52に差し込むとともに螺合部45と第2係合凸部58とを螺合させることにより、雌コネクタ50と雄コネクタ40とを相互に連結することができる。雌コネクタ50と雄コネクタ40とが連結した状態では、雄ルアー43と収容部52とが相互に嵌合し、互いに密着する。
また、図8に示すように、連結部72を収容部52に差し込むとともに係合凸部72aと係合凹部56とを螺合させることにより、雌コネクタ50と線状体側コネクタ70とを相互に連結することができる。なお、雌コネクタ50と線状体側コネクタ70とが連結した状態では、例えば、連結部72と収容部52とは相互に嵌合状態にはならず、互いに密着はしない。
そして、収容部52は、一端52aに開口53を有しているとともに、開口53からの深さ方向に向かって当該収容部52の内径が小さくなる雌ルアーであり、雌ルアーの内周面54に螺旋溝(係合凹部56)が形成されている。
副管23、可撓性チューブ11及び線状体60は、例えば、軟質樹脂により構成されており、可撓性を有しており、柔軟に屈曲可能となっている。
吸盤部12は、例えば、軟質樹脂により構成されている。
三方バルブ24、雄コネクタ40及び雌コネクタ50は、例えば、それぞれ硬質樹脂により構成されている。
連結部材13は、例えば、樹脂(硬質樹脂又は軟質樹脂)により構成されている。
線状体側コネクタ70の第1部材75は、例えば、樹脂(軟質樹脂又は硬質樹脂)により構成されている。
線状体側コネクタ70の第2部材76は、例えば、硬質樹脂により構成されている。
一方、処置具用部品10としては、図9に示すタイプ2を用いることもできる。図9に示す処置具用部品10の場合、吸盤部12の長手方向が連結部材13の長手方向に対して直交して配置されている。
これにより、タイプ1の処置具用部品10とタイプ2の処置具用部品10とのうち、施術者の好みに合う方、又は、必要な施術に相応しい方を選択して用いることが可能となる。
その一方で、胸壁97における開創部93の周囲の部分に、開創部93よりも小さい複数の小切開孔95を形成する。小切開孔95の数は、冠状動脈バイパス術用処置具100が備える処置具用部品10の数と等しくすることができ、本実施形態の場合、例えば3つとする。
なお、各小切開孔95内には、留置型シース(不図示)が設けられてもよい。
次に、図12(a)に示すように、鉗子91の先端側を被験体92の外部から小切開孔95を介して胸腔96に差し込み、処置具用部品10の線状体側コネクタ70の突起部73を鉗子91で掴む。
そして、鉗子91を牽引することにより、線状体側コネクタ70及び雌コネクタ50と、線状体60及び可撓性チューブ11の一部分とを、小切開孔95を介して胸腔96から引き出す。なお、この状態で、処置具用部品10における吸盤部12及び連結部材13側の部分は、胸腔96内に位置する。
そして、図12(b)に示すように、吸盤部12を心臓94の所望の吸着部位の近傍に配置する。
また、線状体側コネクタ70を雌コネクタ50から分離させる。
また、被験体92の外部において、雌コネクタ50をジョイント部20の雄コネクタ40と連結させる。
この作業を各処置具用部品10について繰り返す。
その結果、ジョイント部20の各雄コネクタ40に対してそれぞれ処置具用部品10が接続された状態となる(図1参照)。
その後、各処置具用部品10の吸盤部12を心臓94の所望の吸着部位にあてがい、吸引源30を稼働させ、各吸盤部12を心臓94に吸着させる。
こうして、心臓94を所望の位置に保持することができる。
その後、冠状動脈バイパス術を行うことができる。
よって、各処置具用部品10の雌コネクタ50及び線状体側コネクタ70と可撓性チューブ11及び線状体60の一部分とを、それぞれ対応する小切開孔95から引き出すことができる。
このため、各吸盤部12を所望の位置に配置する作業や、その後の冠状動脈バイパス術の際に、可撓性チューブ11や線状体60が邪魔にならないようにできる。
よって、開創部93を従来よりもコンパクトにしても、冠状動脈バイパス術や、その準備(吸盤部12の配置等)を好適に行うことができる。
このため、冠状動脈バイパス術用処置具100のハンドリング性が良好なものとなる。
例えば、ジョイント部20から取り外した可撓性チューブ11を開創部93(図11)から胸腔96(図11)内に挿入し、小切開孔95(図12(a)、(b))から可撓性チューブ11を引き出して、該可撓性チューブ11をジョイント部20に接続することができる。
よって、各処置具用部品10の雌コネクタ50及び線状体側コネクタ70と可撓性チューブ11及び線状体60の一部分とを、それぞれ対応する小切開孔95から引き出す作業を容易に行うことができる。
これにより、開創部93を小さくすることができるため、生体の負担を低減することが可能である。
また、突起部73が先細形状であるため、図12(b)のように処置具用部品10を胸腔96から引き出す際の抵抗を低減することができる。
よって、線状体側コネクタ70の連結部72を、雄コネクタ40の雄ルアーロック構造46よりもコンパクトにすることができる。すなわち、少なくとも連結部72の外径を雄ルアーロック構造46の外径(筒部44の外径)よりも小さくすることができる。
次に、図13から図16を用いて第1-2実施形態を説明する。
本実施形態に係る処置具用部品10(図13)は、以下に説明する点で、上記の第1-1実施形態に係る処置具用部品10(図3に示す処置具用部品10、又は、図9に示す処置具用部品10)と相違しており、その他の点では、上記の第1-1実施形態に係る処置具用部品10と同様に構成されている。
第1-1実施形態と同様に、連結部72の外周面には係合凸部72aが形成されている。
本実施形態の場合も、図15に示すように、雌コネクタ50と線状体側コネクタ70とを相互に連結することができる。
本体部71の内部には、線状体60の他端側60bを嵌入固定するための固定孔71aが形成されている。
ここで、本実施形態では、線状体側コネクタ70の両端間に亘って貫通孔が形成されている例を示すが、本発明は、この例に限らず、線状体側コネクタ70における固定孔71a以外の部分(挿入突部72等)は、非中空の、中実構造であってもよい。
本体部71の外周面は、当該本体部71の他端側(連結部72側とは反対側)に向けて縮径するテーパー面71bを含んでいる。
本実施形態の場合、線状体60は、本体部71における連結部72側とは反対側から導出されている。
この補強部80は、例えば、線状体60の周囲に補強管81が外嵌されることにより構成されている。
本実施形態の場合、処置具用部品10を胸腔から引き出す際に、図16に示すように鉗子91で補強部80を掴むことができる。
この場合、線状体側コネクタ70は、雄コネクタ40と連結可能な雌コネクタ(第2雌コネクタ)となる。
図17に示すように、この変形例に係るジョイント部側コネクタ40は、第1部材40aと第2部材40bとの2つの部材を備えて構成されている。
第1部材40aは、先端側に雄ルアー43を有している。
第1部材40aにおいて、雄ルアー43の基端側に隣接する部分は、円管状の大径部48となっている。
更に、第1部材40aにおいて、大径部48の基端側に隣接する部分(第1部材40aの基端部)は、円管状の小径部47となっている。
大径部48の外径は、小径部47の外径よりも大径であるとともに、雄ルアー43の外径よりも大径となっている。
第1部材40aにおける小径部47から大径部48にかけての部位の貫通孔42は、当該貫通孔42における他部よりも大径の副管固定部42aとなっている。
小径部47の外面には、第1部材40aに対して第2部材40bが相対的に軸方向に移動することを規制する移動規制リブ49が形成されている。
第2部材40bにおいて、筒部44の基端側に隣接する部分は、円筒状の軸受部44cとなっている。
第2部材40bにおいて、軸受部44cの基端側に隣接する部分(第2部材40bの基端部)は、円筒状(リング状)の基端側縮径部44bとなっている。
軸受部44cの内径は、第1部材40aの大径部48の外径よりも若干大きい。
基端側縮径部44bの内径は、第1部材40aの大径部48の外径よりも小さく、且つ、第1部材40aの小径部47の外径よりも若干大きい。
よって、第1部材40aと第2部材40bとは、軸周りに相互に回転可能となっている。
このため、ジョイント部側コネクタ40の第2部材40bと雌コネクタ50とが連結された状態において、第1部材40aと、第2部材40b及び雌コネクタ50とが、軸周りに相互に回転可能となる。
つまり、雌コネクタ50とジョイント部側コネクタ40とが連結した状態で、可撓性チューブ11と副管23とが相互に軸回転自在となる。
なお、第1部材40aと第2部材40bとが相互に軸方向に移動することが規制されている。すなわち、第2部材40bが第1部材40aに対して相対的に図17における左方に移動しようとすると、基端側縮径部44bが大径部48と干渉することで移動が規制される。逆に、第2部材40bが第1部材40aに対して相対的に図17における右方に移動しようとすると、基端側縮径部44bが移動規制リブ49と干渉することで移動が規制される。

そして、係合凸部72aと係合凹部56とが螺合することにより雄コネクタと雌コネクタ50とが接続される。
また、本実施形態に係る冠状動脈バイパス術用処置具100の各構成要素は、個々に独立した存在である必要はない。複数の構成要素が一個の部材として形成されていること、一つの構成要素が複数の部材で形成されていること、ある構成要素が他の構成要素の一部であること、ある構成要素の一部と他の構成要素の一部とが重複していること、等を許容する。

このうち処置具用部品10が医療用コネクタ200を備えて構成されている。したがって、冠状動脈バイパス術用処置具100も医療用コネクタ200を備えて構成されている。
主管22は、当該主管22の遠位端から近位端に亘って、当該主管22の内部を気体が流通可能な管状部材である。
また、副管23は、当該副管23の遠位端から近位端に亘って、当該副管23の内部を気体が流通可能な管状部材である。
各副管23の近位端は、主管22の遠位端に対して連通している。したがって、ジョイント部20には、主管22の近位端から各副管23の遠位端に亘って、一連の吸引路21が形成されている。
各副管23には、当該副管23の内部を気体が流通可能な開状態と、当該副管23内での気体の流通を遮断する閉状態と、の切り替え操作を行うための三方バルブ24が設けられている。

貫通孔42における本体部41の他端側の部分は、例えば、貫通孔42における雄ルアー43の先端側の部分よりも小径の副管固定部42aとなっている。
副管固定部42aに対して副管23の遠位端が差し込まれることによって、副管23の遠位端がジョイント部側コネクタ40に固定されている。
処置具用部品10は、更に、可撓性の線状体60と、雄コネクタである線状体側コネクタ70と、を備えている。
連結部材13には、第1差込孔13aと第2差込孔13bとが形成されている。

収容部52の内周面54には、螺旋状の係合凹部56(螺旋溝)が形成されている。
このように、挿入突部72の外周面に係合凸部72aが形成され、収容部52の内周面に係合凹部56が形成されている。
収容部52の係合凹部56と挿入突部72の係合凸部72aとが螺合することによって、雌コネクタ50と線状体側コネクタ70とが着脱可能に連結されるようになっている。
ただし、本発明は、この例に限らず、挿入突部72の外周面に係合凹部56が形成されている一方で、収容部52の内周面54に係合凸部72aが形成されていて、これら係合凹部56と係合凸部72aとが螺合されることで雌コネクタ50と線状体側コネクタ70とが連結されるようになっていてもよい。
また、収容部52は、開口53からの深さ方向に向かって当該収容部52の内径が小さくなる雌ルアーである。すなわち、図5の左方に向けて、収容部52の内径が徐々に小さくなっている。
また、収容部52の外周面における収容部52の一端52aの近傍には、第2係合凸部58が形成されている。
よって、雌コネクタ50をジョイント部側コネクタ40にも連結することができる。
なお、収容部52の一端52aは、雌コネクタ50の一端でもある。
すなわち、雌コネクタ50は、一端52aに開口53を有し、開口53からの深さ方向に向かって内径が小さくなる中空の雌コネクタ50であって、当該雌コネクタ50の外周面における一端52aの近傍に突起部(第2係合凸部58)が形成されており、雌コネクタ50の内周面に螺旋状の凹溝(係合凹部56)が形成されている医療用コネクタである。
このため、雌コネクタ50は、ジョイント部側コネクタ40と線状体側コネクタ70とのいずれに対しても連結することができる。また、雌コネクタ50がジョイント部側コネクタ40と連結された際には、ルアー嵌合構造を実現することができる。
大径部521と小径部522とは、互いに同軸に配置され、且つ、軸方向において相互に連接されている。
そして、第2係合凸部58は、大径部521の外周面に形成されている。
差込管部59の外周面は、例えば、小径部522の外周面よりも更に小径に形成されている。
また、雌コネクタ50の収容部52の外周面において第2係合凸部58が形成されている位置は、図7、図8及び図10に示す例のように、一端52aから離間していても良いし、図4(a)、図4(b)、図4(c)、図5及び図6に示す例のように、一端52aと隣接していても良い。いずれにしても、雌コネクタ50は、ジョイント部側コネクタ40と線状体側コネクタ70とのいずれに対しても連結可能に形成されている。
すなわち、図6に示すように、雄ルアー43を収容部52に差し込むとともに螺合部45と第2係合凸部58とを螺合させることにより、雌コネクタ50とジョイント部側コネクタ40とを相互に連結することができる。雌コネクタ50とジョイント部側コネクタ40とが連結した状態では、雄ルアー43と収容部52とが相互に嵌合し、互いに密着する。
また、図8に示すように、挿入突部72を収容部52に差し込むとともに係合凸部72aと係合凹部56とを螺合させることにより、雌コネクタ50と線状体側コネクタ70とを相互に連結することができる。なお、雌コネクタ50と線状体側コネクタ70とが連結した状態では、例えば、挿入突部72と収容部52とは相互に嵌合状態にはならず、互いに密着はしない。
換言すれば、線状体側コネクタ70の本体部71の外径と、雌コネクタ50の第2係合凸部58の外径とが互いに同等であり、且つ、線状体側コネクタ70と雌コネクタ50とが相互に連結された状態で、本体部71と第2係合凸部58とが互いに同軸に配置されるようになっている。
副管23、可撓性チューブ11及び線状体60は、例えば、軟質樹脂により構成されており、可撓性を有しており、柔軟に屈曲可能となっている。
吸盤部12は、例えば、軟質樹脂により構成されている。
三方バルブ24、ジョイント部側コネクタ40及び雌コネクタ50は、例えば、それぞれ硬質樹脂により構成されている。
連結部材13は、例えば、樹脂(硬質樹脂又は軟質樹脂)により構成されている。
線状体側コネクタ70の第1部材75は、例えば、樹脂(軟質樹脂又は硬質樹脂)により構成されている。
線状体側コネクタ70の第2部材76は、例えば、硬質樹脂により構成されている。
その一方で、胸壁97における開創部93の周囲の部分に、開創部93よりも小さい複数の小切開孔95を形成する。小切開孔95の数は、冠状動脈バイパス術用処置具100が備える処置具用部品10の数と等しくすることができ、本実施形態の場合、例えば3つとする。
なお、各小切開孔95内には、留置型シース(不図示)が設けられてもよい。
次に、図12(a)に示すように、鉗子91の先端側を被験体92の外部から小切開孔95を介して胸腔96に差し込み、処置具用部品10の線状体側コネクタ70の突起部73を鉗子91で掴む。
そして、鉗子91を牽引することにより、線状体側コネクタ70及び雌コネクタ50と、線状体60及び可撓性チューブ11の一部分とを、小切開孔95を介して胸腔96から引き出す。なお、この状態で、処置具用部品10における吸盤部12及び連結部材13側の部分は、胸腔96内に位置する。
そして、図12(b)に示すように、吸盤部12を心臓94の所望の吸着部位の近傍に配置する。
また、線状体側コネクタ70を雌コネクタ50から分離させる。
また、被験体92の外部において、雌コネクタ50をジョイント部20のジョイント部側コネクタ40と連結させる。
この作業を各処置具用部品10について繰り返す。
その結果、ジョイント部20の各ジョイント部側コネクタ40に対してそれぞれ処置具用部品10が接続された状態となる(図1参照)。
その後、各処置具用部品10の吸盤部12を心臓94の所望の吸着部位にあてがい、吸引源30を稼働させ、各吸盤部12を心臓94に吸着させる。
こうして、心臓94を所望の位置に保持することができる。
その後、冠状動脈バイパス術を行うことができる。
よって、各処置具用部品10の雌コネクタ50及び線状体側コネクタ70と可撓性チューブ11及び線状体60の一部分とを、それぞれ対応する小切開孔95から引き出すことができる。
このため、各吸盤部12を所望の位置に配置する作業や、その後の冠状動脈バイパス術の際に、可撓性チューブ11や線状体60が邪魔にならないようにできる。
よって、開創部93を従来よりもコンパクトにしても、冠状動脈バイパス術や、その準備(吸盤部12の配置等)を好適に行うことができるため、生体の負担を低減することが可能である。
なお、第2係合凸部58の外径は、例えば、ジョイント部側コネクタ40との連結に必要な最低限の大きさを有している。そして、第2係合凸部58の外径と本体部71の外径とが同等であるということは、本体部71の寸法が極力コンパクトであることも意味する。
次に、図13から図18を用いて第2-2実施形態を説明する。
本実施形態に係る医療用コネクタ200は、以下に説明する点で、上記の第2-1実施形態に係る医療用コネクタ200と相違しており、その他の点では、上記の第2-1実施形態に係る医療用コネクタ200と同様に構成されている。
すなわち、本実施形態に係る医療用コネクタ200は、第2-1実施形態に係る医療用コネクタ200と比べて、線状体側コネクタ70の構造が相違している。
なお、本実施形態に係る処置具用部品10(医療機器;図13)は、本実施形態に係る医療用コネクタ200を備えて構成されている。
第2-1実施形態と同様に、挿入突部72の外周面には係合凸部72aが形成されている。
本実施形態の場合も、図18に示すように、雌コネクタ50と線状体側コネクタ70とを相互に連結することができる。
本体部71の内部には、線状体60の他端側60bを嵌入固定するための固定孔71aが形成されている。
すなわち、線状体側コネクタ70(雄コネクタ)は、本体部71と挿入突部72とに亘って貫通孔79が形成された管状体である。
なお、貫通孔79の一部分により固定孔71aが構成されている。
本実施形態の場合、線状体60は、本体部71における挿入突部72側とは反対側から導出されている。
この補強部80は、例えば、線状体60の周囲に補強管81が外嵌されることにより構成されている。
本実施形態の場合、処置具用部品10を胸腔から引き出す際に、図18に示すように鉗子91で補強部80を掴むことができる。よって、線状体60を直に掴んだり、可撓性チューブ11を掴んだりする必要が無く、線状体60や可撓性チューブ11の損傷を抑制できる。
図17に示すように、この変形例に係るジョイント部側コネクタ40は、第1部材40aと第2部材40bとの2つの部材を備えて構成されている。
第1部材40aは、先端側に雄ルアー43を有している。
第1部材40aにおいて、雄ルアー43の基端側に隣接する部分は、円管状の大径部48となっている。
更に、第1部材40aにおいて、大径部48の基端側に隣接する部分(第1部材40aの基端部)は、円管状の小径部47となっている。
大径部48の外径は、小径部47の外径よりも大径であるとともに、雄ルアー43の外径よりも大径となっている。
第1部材40aにおける小径部47から大径部48にかけての部位の貫通孔42は、当該貫通孔42における他部よりも大径の副管固定部42aとなっている。
小径部47の外面には、第1部材40aに対して第2部材40bが相対的に軸方向に移動することを規制する移動規制リブ49が形成されている。
第2部材40bにおいて、筒部44の基端側に隣接する部分は、円筒状の軸受部44cとなっている。
第2部材40bにおいて、軸受部44cの基端側に隣接する部分(第2部材40bの基端部)は、円筒状(リング状)の基端側縮径部44bとなっている。
軸受部44cの内径は、第1部材40aの大径部48の外径よりも若干大きい。
基端側縮径部44bの内径は、第1部材40aの大径部48の外径よりも小さく、且つ、第1部材40aの小径部47の外径よりも若干大きい。
よって、第1部材40aと第2部材40bとは、軸周りに相互に回転可能となっている。
このため、ジョイント部側コネクタ40の第2部材40bと雌コネクタ50とが連結された状態において、第1部材40aと、第2部材40b及び雌コネクタ50とが、軸周りに相互に回転可能となる。
つまり、雌コネクタ50とジョイント部側コネクタ40とが連結した状態で、可撓性チューブ11と副管23とが相互に軸回転自在となる。
なお、第1部材40aと第2部材40bとが相互に軸方向に移動することが規制されている。すなわち、第2部材40bが第1部材40aに対して相対的に図17における左方に移動しようとすると、基端側縮径部44bが大径部48と干渉することで移動が規制される。逆に、第2部材40bが第1部材40aに対して相対的に図17における右方に移動しようとすると、基端側縮径部44bが移動規制リブ49と干渉することで移動が規制される。
