Claims (3)
- 圧縮空気のエネルギーをピストンの直線運動に変換して出力する空気圧アクチュエータであって、
前記ピストンを軸方向に摺動自在に収容する円筒状のシリンダ孔を有するアクチュエータ本体と、
前記シリンダ孔の軸方向に対して垂直な引っ掛け面を備え、前記シリンダ孔の内周面に形成されたリング状の溝部と、
前記ピストンに固定されたピストンロッドが貫通する貫通孔を備えるとともに外側の軸方向端面に該端面に開口する凹部を備え、前記シリンダ孔内に設けられて前記シリンダ孔を閉塞する樹脂製の閉塞部材と、
前記閉塞部材の外側の軸方向端面に同一面状に連なる平面状の係止面を備え、前記閉塞部材の外周部に一体に設けられて前記凹部に向けて径方向に弾性変形自在の爪部とを有し、
前記爪部の係止面を前記溝部の引っ掛け面に沿って係合させることにより前記閉塞部材を前記シリンダ孔内に固定することを特徴とする空気圧アクチュエータ。 - 請求項1記載の空気圧アクチュエータにおいて、前記シリンダ孔が底付き孔であることを特徴とする空気圧アクチュエータ。
- 請求項1または2記載の空気圧アクチュエータにおいて、前記閉塞部材の外周に装着されて前記シリンダ孔の内周面と前記閉塞部材との間から圧縮空気が外部に漏れ出すことを防ぐOリングと、前記閉塞部材の内周に装着されて前記貫通孔から圧縮空気が外部に漏れ出すことを防ぐロッドパッキンとを有することを特徴とする空気圧アクチュエータ。
