Abstract
An actuator includes an actuator body, an output piston portion, an ignition device and a sealing member formed of a metal plate-like member. The sealing member separates a space in the actuator body into a first space where the ignition device is disposed and a second space where the output piston portion is disposed, and seals a combustion product generated by the ignition device in the first space. A peripheral edge portion of the sealing member is fixed to an inner wall that defines the space. The sealing member is deformed by the gunpowder combustion such that its central portion is displaced to a side of the output piston portion, to thereby press the output piston portion using the central portion and cause the output piston portion to slide in the through hole. With this, energy for driving an output piston portion is suitably transmitted to the output piston portion.
