Abstract
A gas generator includes, inside a housing, an ignition device chamber accommodating a transfer charge and an igniter in which an igniter main body is surrounded by an igniter collar. The ignition device chamber is formed such that an inner circumferential wall surface on an opening side of an ignition device chamber cup, which is charged with the transfer charge, is press-fitted to and in close contact with an outer circumferential wall surface of the igniter collar of the igniter. The ratio (Vh/Vh) of an average Vickers hardness (Vh) of the igniter collar, which is measured by a method described in Examples, and an average Vickers hardness (Vh) of the ignition device chamber cup, which is measured by a method described in Examples, is within a range of 0.25 to 0.65.
