The surface 27 on the occupant side of the housing 3 which opens and extends forward is extended by the deployment of the airbag 1, and the airbag 1 deployed forward can be guided by the surface 27 on the occupant side. It is possible to prevent the airbag 1 that inflates vigorously from directly hitting the occupant. In addition, the long surface 27 on the occupant side has a large force to push the pad 22 and the skin cover 23 and the like.
