In order to provide an inflator which is capable of generating an impulse wave and allowing the impulse wave to burst the gas exit of the pressure container to inject gas therefrom even with the initiator which cannot generate high-pressure gas outstandingly rapidly, a pressure container (4) is provided with a tube (14) extending into a gas storage (2) so as to direct toward a gas jet port (6) at the rear end thereof and an initiator (16) fitted into the rear end of the tube (14). The distal end of the pressure container (4) is closed by a closure disk (18). The tube (14) is filled with gas whereof the pressure is lower than the pressure in the gas storage (2). The initiator (16) injects high-pressure gas into the tube (14) and generates an impulse wave. The impulse wave breaks the closure disk (18) and propagates in the gas storage (2), and then bursts a burst disk (8) when it reaches the gas jet port (6). <IMAGE> |
