PROBLEM TO BE SOLVED: To provide an actuator which can be configured compactly by making length short, even when it is configured to use a gas generator for generating gas for actuation at actuation time.SOLUTION: An actuator includes: a gas generator 70 for generating a gas for actuation at actuation time; a storage side part 22 for storing and holding the gas generator; and a pressing side part 52 for moving forward so as to be separated from the storage side part by the gas for actuation. The pressing side part and the storage side part are disposed in a mutually slidable manner. One of mutual slide portions 22a, 52a of the pressing side part and the storage side part is arranged on an inner side close to a movement central axis C of the pressing side part as the inside portion 22a, and the other of the mutual slide portions is disposed as the outside portion 52a for surrounding the periphery of the inside portion 22a. The gas generator 70 is stored and held in the storage side part 22 in such a manner that it is closer to the movement central axis C side than the slide portion 52a of the pressing side part, and it overlaps with one part 52b of the pressing side part 52 in an arrangement state before actuation.

    【課題】作動時に作動用ガスを発生させるガス発生器を使用する構成としても、長さを短くコンパクトに構成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収納側部22と、作動用ガスにより収納側部から離れるように前進移動する押圧側部52と、を備える。押圧側部と収納側部とは、相互に摺動可能に配設される。押圧側部と収納側部との相互の摺動部位22a,52aの一方が、内側部位22aとして、押圧側部の移動中心軸Cに近い内側に配設され、相互の摺動部位の他方が、内側部位22aの周囲を囲む外側部位52aとして、配設される。ガス発生器70は、押圧側部の摺動部位52aより移動中心軸C側に接近して、作動前の配置状態の押圧側部52の一部52bと重なるように、収納側部22に収納保持されている。【選択図】図4
