Title: Inflating type occupant restraint device

Abstract: A receiving case for receiving a gas bag is formed of a side wall portion secured to a fixed member and a lid surface portion thinner than the side wall portion by the use of a material having a comparatively high hardness and a ductility. Further, the lid surface portion is formed with fragile portions contiguous to one another. At the inflation of the gas bag, the receiving case for the gas bag is prevented from scattering in the form of broken pieces, and the gas bag is prevented from being damaged by a sharp edge otherwise arising at the fracture surface of the receiving case.
