PROBLEM TO BE SOLVED: To provide an actuator which can be configured conveniently even when a locking mechanism for regulating movement before an operation is provided.SOLUTION: An actuator includes: a gas generator 70 for generating a gas for an operation at operation time; a gas side part 22 for accommodating and holding the gas generator; and a non-gas side part 52 for relatively moving forward by an amount of an operation stroke so as to be separated from the gas side part by a pressure of the gas for an operation. A locking mechanism FR1 for preventing the frontward movement of the non-gas side part before an operation is configured by disposing an engagement recess part 35 and an engagement protrusion part 63 which are engaged in such a manner that the engagement can be released at the operation time, at positions of the gas side part and the non-gas side part facing with each other before the operation. The engagement protrusion part is locked to a recess part 30 for locking disposed at the non-gas side part 52 in which the engagement recess part is arranged, at the operation completion time after the engagement release with the engagement recess part, and it is shared with a protrusion part for locking which can prevent retreat movement of the non-gas side part 52.SELECTED DRAWING: Figure 4
【課題】作動前の移動を規制する係止機構を設けても簡便に構成することができるアクチュエータを提供すること。【解決手段】作動時に作動用ガスを発生させるガス発生器70と、ガス発生器を収納して保持するガス側部22と、作動用ガスの圧力により、ガス側部から離れるように、作動ストローク分、相対的に前進移動する非ガス側部52と、を備える。作動前の非ガス側部の前進移動を防止する係止機構FR1は、ガス側部と非ガス側部との作動前の相互に対向する位置に、作動時に係合解除可能として係合する係合凹部35と係合凸部63とを、配設させて構成される。係合凸部は、係合凹部との係合解除後の作動完了時、係合凹部を配置させた非ガス側部52に配設されたロック用凹部30に係止されて、非ガス側部52の後退移動を防止可能なロック用凸部と兼用されている。【選択図】図4
