Abstract:
The present invention enhances igniting performance of a gas generating agent in a gas generator. This gas generator includes an igniter assembly that discharges a combustion product and that includes: an igniter main body that is provided with an igniter cup that stores an ignition powder and also cleaves due to the combustion product produced as a result of combustion of the ignition powder and a conductive pin that supplies current for igniting the ignition powder; a collar part that holds the igniter main body; and a holding part that is interposed between the igniter main body and the collar part and that fixes the igniter main body to the collar part. The gas generator also includes: a cylindrical housing that includes a combustion chamber that stores a gas generating agent and in which a gas discharge hole is formed for discharging combustion gas produced as a result of combustion of the gas generating agent; and a cylindrical elastic member that is disposed in the housing between the igniter assembly and the gas generating agent so that an axial direction thereof is arranged in a direction identical to the housing, the elastic member including, on an inner circumference thereof, a regulating part that regulates a direction in which the cleaved igniter cup expands.
