Claims (4)
- ピストン部材と前記ピストン部材に設けられた穴に挿入されたロッド部材とを固定する固定装置であって、
前記ロッド部材の外周面に環状溝が設けられており、
前記ピストン部材の前記穴の周面に一方の端面に開口する凹部が設けられ、
前記凹部は、前記環状溝に対向する位置で前記端面から内部に向かう方向に径小となるテーパ面を有しており、
前記環状溝は、前記テーパ面に対向する部分が、前記テーパ面とほぼ平行なテーパ底面に形成されており、
テーパ面を有しない平板部を有する環状の係止部材が、前記凹部の前記端面の開口部から軸方向に挿入され且つ圧入されることにより、前記平板部が前記テーパ面に沿って内周側に塑性変形して前記テーパ面と前記テーパ底面との間に入り込んでなる、
ことを特徴とする固定装置。 - 前記凹部は、前記開口部と前記テーパ面との間に、前記テーパ面の最大径よりも大きい径の内周面と軸心に垂直な奥端面とを有した収納凹部を有し、
前記係止部材は、その一部が前記環状溝と前記テーパ面との間に挿入され、残りの部分が前記収納凹部に挿入されてなる、
請求項1記載の固定装置。 - 前記係止部材には、前記奥端面に当接してそれ以上の挿入を阻止するための凸部が設けられてなる、
請求項2記載の固定装置。 - 前記ロッド部材には、前記環状溝よりも軸方向の外方において第2の環状溝が設けられており、
前記係止部材の外側の端部が内周側に塑性変形して前記第2の環状溝に入り込んでなる、
請求項1ないし3のいずれかに記載の固定装置。
