1. An actuator comprising:
a gas generator that generates an actuating gas when actuated; a housing section that houses and holds the gas generator; and a pressing section that is deployable, when pressed by an actuating gas generated by the gas generator, in such a fashion as to move forward relative to the housing section and be separated from the housing section, the pressing section comprising a sliding portion that is slidable against a sliding portion of the housing section such that the pressing section and the housing section are slidable against each other, wherein: either one out of the sliding portions of the pressing section and housing section serves as an inner section that is located closer to a moving central axis of the pressing section than the other whereas the other out of the sliding portions of the pressing section and housing section serves as an outer section that surrounds the inner section; and the gas generator is located closer to the moving central axis than the sliding portion of the pressing section and partially overlaps with a part of the pressing section in an inactive state in a direction orthogonal to the moving central axis. |
