Abstract
A gas generator for an air bag includes: a housing having top and bottom plates and a cylindrical wall provided between those plates; a cylindrical filter unit, provided inside the housing, at least one end of the filter unit having an inclining end surface such that the length of the filter unit in an axial direction thereof decreases as the distance from a central axis of the filter in a radial direction increases, an outer peripheral surface of the filter unit and an inner surface of the cylindrical wall defining a plenum; and a supporting portion formed inside the housing and having an inclining surface substantially parallel to the inclining end surface of the filter unit. The supporting portion engages with the inclining end surface such that the plenum is maintained even when the filter unit is urged to expand in the radial direction by the combustion gas.
