Abstract
A gas generator includes a cylindrical housing, a diffuser portion, a first combustion chamber defined by a first porous plate member, a second combustion chamber defined by a second porous plate member, and an ignition device having an ignition portion attached to an igniter collar. The first porous plate member comprises first through holes arranged in the vicinity of a peripheral edge portion. An annular space is formed between an outer peripheral surface of the ignition portion and an inner peripheral wall surface of the cylindrical housing. The height (H) of a top surface of the ignition portion from the igniter collar and a smallest length (Lmin) of a first gas generating agent in the first combustion chamber satisfies a relation Lmin<H. An axis of the cylindrical housing is coincident with a central line of the ignition portion, the first porous plate member, and the second porous plate member.
