The present invention provides a gas generator (10) for an occupant restraining device of a vehicle, comprising
a substantially cup-like shaped diffuser shell (12) having a plurality of gas discharge ports (17),
and a substantially cylindrical filter (20) for purifying and cooling the combustion gas generated from the gas generating agent (25), all accommodated in the housing (11),
the housing (11) formed by inserting part of an outer peripheral surface in the open portion side of the closure shell (13) into part of the inner peripheral surface of the open portion side in the diffuser shell (12) to abut against each other, so that they are integrated,
the filter (20) supported by abutting one end surface (21) thereof against a ceiling surface of the diffuser shell (12) and abutting the other end surface (226) thereof against at least an annular end surface (13d) of the open portion of the closure shell (13),
an annular space provided between the circumferential wall (12b) having the gas discharge ports (17) of the diffuser shell (12) and an outer circumferential surface of the filter (20). |
