- 内壁面の一部に凸部が形成された窪みを有する第1部材と第2部材との間で中心軸の軸方向に圧縮される筒状の熱可塑性エラストマ製のストッパであって、
前記窪みに挿入される環状の取付部と、
前記取付部に連なる前記軸方向の第1端と、前記第1端とは前記軸方向の反対側の第2端とを含み、山と谷とが前記軸方向に連続する蛇腹状に内周面および外周面が形成された筒状の伸縮部と、を備え、
前記取付部は、前記第1端から前記中心軸の軸直角方向の外側へ延びた受圧面部と、
前記受圧面部の前記軸直角方向の外縁部から前記軸直角方向の内側かつ前記第2端とは反対側へ延びた端面部と、を含み、
前記外周面と前記受圧面部とにより前記第1端の前記軸直角方向の外側に谷底が形成され、前記内周面と前記受圧面部とにより前記第1端の前記軸直角方向の内側に山頂が形成され、
前記外縁部は、前記伸縮部の前記外周面の複数の山頂よりも前記軸直角方向の外側に位置することを特徴とするストッパ。 - 前記伸縮部の前記外周面と前記受圧面部とにより形成された谷底の曲率半径は、前記伸縮部の前記外周面の複数の谷底の曲率半径よりも小さいことを特徴とする請求項1記載のストッパ。
- 前記端面部のうち前記受圧面部とは反対側の外面は、前記窪みに前記取付部を挿入していない状態で、前記外縁部から前記軸方向へ離れるにつれて前記軸直角方向の内側へ傾斜することを特徴とする請求項1又は2に記載のストッパ。
- 前記端面部は、前記中心軸を含む断面において前記軸直角方向の外側へ凸状に湾曲し、
前記外周面と前記受圧面部とにより形成された谷底の曲率半径は、前記外縁部の前記軸直角方向の内側の谷底の曲率半径よりも小さく、
前記外縁部の前記軸直角方向の内側の谷底の曲率半径は、前記端面部のうち前記受圧面部に面する内面の曲率半径よりも小さいことを特徴とする請求項3記載のストッパ。 - 前記端面部は、前記中心軸を含む断面において直線状に形成され、
前記外縁部の前記軸直角方向の内側の谷底の曲率半径は、前記外周面と前記受圧面部とにより形成された谷底の曲率半径よりも小さいことを特徴とする請求項1から3のいずれかに記載のストッパ。 - 前記第1端は、前記伸縮部の前記内周面の複数の山頂よりも前記軸直角方向の内側に位置することを特徴とする請求項1から5のいずれかに記載のストッパ。
