A gas generator for air bags for use in an air bag system for safely protecting a driver and riders in a vehicle from shock from collisions. The system includes a housing (3) formed by a side cylinder (1b) with a plurality of gas exhaust openings (8) the housing being closed at its ends by an upper cap (1a) and a lower cap (2a); an igniting device (16), provided in the housing (3) at a center portion thereof; gas generating agents (6), provided in the housing (3) at a location radially outside of the igniting device (16), to be burnt to generate gas; a cooling/filtering member (7) provided in the housing (3) at a location radially outside of the gas generating agents (6) to enclose the gas generating agents and extending from the side of the upper cap (1a) to the side of the lower cap (2a); and an annular projection (50) for preventing the gas generated by the burning of the gas generating agents (6) from flowing toward an end portion of the cooling/filtering member (7). The annular projection (50) is integrally formed on at least one of the upper cap (1a) and the lower cap (2a) so as to abut with an inner peripheral surface of the cooling/filtering member (7).
