Claim Text:
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, 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 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, the gas generator is located closer to the 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 central axis, the housing section includes at a leading end thereof an opening end for releasing an actuating gas and houses the gas generator, the sliding portion of the housing section is located on an outer circumference of the housing section and constitutes the inner section, the housing section serves as an inner member, the pressing section includes a ceiling wall that covers the opening end of the housing section and a circumferential wall that covers a region of the outer circumference of the housing section from an outer peripheral edge of the ceiling wall up to at least an area where the gas generator is located, the sliding portion of the pressing section is comprised of an inner circumference of the circumferential wall and constitutes the outer section, and the pressing section serves as an outer member that surrounds the housing section as the inner member.
