Abstract
An actuator which has an operating pin of the invention includes a piston which has an operating pin, a squib, and a cylinder case for holding the piston, in which the piston is moved rearward along with the operating pin by a driving gas generated injected from the squib into the cylinder case. A cap portion for covering the side of the squib with a gas injection port comprises a cylindrical side portion and a front end wall portion, and the operating pin is projected from the center of this front end wall portion. The cap portion is arranged with injection holes through which the driving gas is injected. Forward movement of the piston before the actuator is operated is restricted by the front end wall portion of the cylinder case coming into contact with the ceiling wall portion of the cylinder case.
