Airbag inflator
An airbag inflator in which a pressure vessel constituted by a base and a diffuser accommodates an igniter, a gas generating agent, a filter, and an inner cover that covers the gas generating agent and includes a bent portion that contacts an inner wall of the filter. The filter has a layered structure constituted by an inner filter and a wire mesh outer filter. The inner filter is of a cylindrical shape, in which upper and lower end portions are formed in a tapered shape that decreases in height toward an outer peripheral side. The wire mesh outer filter is fitted over an outer peripheral surface of the inner filter, excluding at least the respective end portions formed in the tapered shape, and has a slightly larger outer diameter than an inner diameter of the base. The filter is press-fitted into the base. Thus, the filter can be incorporated into the base easily. Further, close contact with the inner cover can be maintained when the diffuser and the base are integrated by welding.
