Abstract
【解決手段】アクチュエータは、バレル16とその中に収容されるプランジャ22とを含む。クラッチ機構はプランジャ22とバレル16間で作用でき、接続されている状態ではプランジャ22は回転してバレル16に対して前進する。プランジャ22に対する軸方向負荷はクラッチ機構を開放し、プランジャ22は軸方向に進む。プランジャ22にはプランジャ22に対して回転可能なカラー27が配設されており、プランジャ22は後方へ直動されると回転しながら後退する。プランジャ22の先端に貫通開口が形成されたブシュ28が配設され、貫通開口に弾性リング35が配設されている。これにて、所定の摩擦反力が生じプランジャ22が自重で後退することが防止される。
