ABSTRACT:
A gas generator includes, a housing having a gas discharge port; at least one combustion chamber accommodating a gas generating agent therein; a cylindrical filter disposed between the gas discharge port and the combustion chamber; and at least one ignition device for igniting and combusting the gas generating agent, each device comprising an igniter assembly in which an electric igniter is enclosed and fixed by a metal member and a resin portion. The igniter assembly has, in the resin portion, a holder accommodation space disposed over an opening formed in a bottom portion of the housing, and fixed by a holder inserted from the outside into the opening. An inner wall surface of the holder accommodation space has concave and convex portions that engage convex and concave portions of the holder, so that the igniter assembly is fixed without being welded to the bottom portion of the housing.
