Abstract
Abstract A retainer (15) adapted to fix an air bag (14) to a base plate (11) includes an expanded portion (15b) for covering an inflator (12). An angled portion (15d) of the expanded portion (15b) is provided with radially arranged gas through holes (15f). The center portion of an upper fabric material (14a) of the air bag (14) is affixed to the center of a top plate portion (15e) of the expanded portion (15b) by means of a rivet (41), thereby limiting the distance by which the air bag (14) projects toward the occupant.
