Abstract

An actuator AEincludes a lock mechanism Rconfigured to fill a gas G generated by operating a gas generatorat inside of a cylinderand moving forward a pistonalong with a support rodfor restricting a rearward movement of the support rod moved forward. The support rodis arranged to be able to absorb a kinetic energy of a protection object person and capable of being plastically deformed when the protection object person is received by a receiving member after having been moved forward. A lock mechanism Ris constituted by a diameter enlarging deformed portionarranged at a piston and a locking stepped portioncapable of restricting the rearward movement of the piston. Further, the diameter enlarging deformed portionis locked by the locking stepped portionby being elastically deformed by an elastic force of the diameter enlarging deformed portionper se from a diameter contracting state to a diameter enlarging state when arranged to the locking stepped portionafter moving the piston forward.
