In order to provide an airbag retainer having an advantage of reduced cost and weight, a retainer (20) has an upper retainer (21) for housing an airbag (10) and a lower retainer (31) for holding an inflator (I). The upper retainer (21) is made of a resin or a metal including a magnesium alloy, and the lower retainer (31) is made of a metal. The upper retainer (21) has a rectangular frame-like structure having sidewalls (21A to 21D) on the four sides thereof. The lower retainer (31) has a bottom portion (32) for accommodating the inflator (I). Sidewalls (31A and 31B) stand up on upper edges (31x and 31y) of the bottom portion (32), respectively, extending along the longitudinal direction of the bottom portion (32). The sidewalls (31A and 31B) are located inside the sidewalls (21A and 21B) respectively, in a state such that the upper retainer (21) and the lower retainer (31) are assembled. In this state, the sidewalls (31A and 31B) of the lower retainer (31) partly overlap the sidewalls (21A and 21B) of the upper retainer (21) respectively. <IMAGE> |
