A passenger airbag apparatus includes an airbag, an inflator, a case and a retainer. The case includes on a bottom wall a set-in opening through which the inflator is set in, a housing region that holds and houses the inflator, a mounting seat on which the airbag is mounted, lateral movement stopping sections that prevent the inflator from moving in an axial direction, and a rotation stopping section that prevents the inflator from rotating in a circumferential direction. The inflator includes a cut-out region engageable with the rotation stopping section. The retainer is secured to the mounting seats of the case with bolts while pressing a hem of an opening of the airbag against an upper circumferential plane of the inflator and the mounting seats, thus mounting the airbag and inflator on the case. |
