A gas generator (1A) has an approximately cylindrical housing in which an ignition chamber (13), first and second combustion chambers (23 and 33), and first and second discharge paths disposed therein. The ignition chamber (13) is disposed in a base portion (10) of the housing and contains an igniter (12) and an enhancer agent (14) stored therein. The first and second combustion chambers (23, 33) are disposed respectively in first and second cylindrical portions (20, 30) of the housing and each contains a gas generating agent. The first and second discharge paths are disposed respectively on the front end sides of the first and second cylindrical portions (20, 30) of the housing and serve to enable gases generated in the first and second combustion chambers (23, 33) to be discharged from the housing therethrough. The inner diameter (r1) of the first combustion chamber (23) and the inner diameter (r2) of the second combustion chamber (33) are suitably regulated so as to differ from each other. Because of such a configuration, in a gas generator having two or more gas output portions driven by one igniter, the outputs in the respective gas output portions can be made different from each other while a size increase of the gas generator and the slower start-up of the gas output in each gas output portion are prevented. |
