Abstract
An actuator for use in an air bag device which is inflated by a gas as a firing pin is moved by the movement of an inertia member to actuate a gas generator and in a preloader of a webbing retractor actuated by the gas. A contact is provided for outputting an electrical signal by being turned on at the time of movement of the inertia member or movement of the firing pin. Accordingly, by providing another gas generating means adapted to be actuated in correspondence with an output of this contact, it is possible to actuate a plurality of air bag devices or preloaders.
