Abstract
A gas generator includes, a cylindrical housing provided with an ignition device and a diffuser, and an inner cylindrical member defining a gap with an inner circumferential wall surface of the cylindrical housing and leading to a gas discharge port. The inner cylindrical member is formed of a plurality of cylindrical members having gas inlet-outlet holes and connected in an axial direction. An opening of each of the cylindrical members has concave-convex portions for fitting the cylindrical members together. Both ends of the connected cylindrical members have a first protrusion on a side of the ignition device serving as a first abutment portion, and a second protrusion on the side of the diffuser portion serving as a second abutment portion. The first and second abutment portions abut the inner circumferential wall surface of the cylindrical housing and have a hole or a cutout to allow a gas to pass.
