In the gas generator, a plurality of gas discharge holes include a plurality of first gas discharge holes and one or a plurality of second gas discharge holes whose opening pressure is higher than that of the first gas discharge holes. The opening pressure of the first gas discharge holes and the opening pressure of the second gas discharge holes are set such that when the igniter is operated in a separate state before the gas generator is installed in the airbag device, only the plurality of first gas discharge holes among the plurality of gas discharge holes are opened by the pressure of the gas. When the igniter is operated in the assembled state, first gas discharge holes except a part of the first gas discharge holes and at least a part of the second gas discharge holes among the plurality of gas discharge holes are opened by the pressure of the gas.
在气体发生器中,多个气体排出孔包括多个第一气体排出孔和开口压力比第一气体排出孔的开口压力高的一个或多个第二气体排出孔,第一气体排出孔的开口压力和第二气体排出孔的开口压力被设定为:在气体发生器被装入气囊装置之前的状态的单独状态下点火器工作时,仅多个气体排出孔中的多个第一气体排出孔通过气体的压力而开口,在组装状态下点火器工作时,多个气体排出孔中的除了一部分第一气体排出孔以外的第一气体排出孔和至少一部分第二气体排出孔通过气体的压力而开口。
