また、油圧室は、締結用油圧室と解放用油圧室とを備え、締結用油圧室及び解放用油圧室は、付勢部材と軸方向にオーバーラップする位置且つ径方向に異なる位置に配置されることにより、締結用油圧室及び解放用油圧室を付勢部材と軸方向にオーバーラップさせない場合に比して軸方向にコンパクトに構成することができる。
また、解放用油圧室は、締結用油圧室より外径が小さく形成され、解放用油圧室の外周側に、ピストンに結合されると共に付勢部材による付勢力を受ける付勢受け部材が配設されることにより、締結用油圧室より外径が小さく形成された解放用油圧室の外周側において付勢受け部材をピストンに結合させることができ、解放用油圧室の外周側のスペースを有効に利用することができる。
