Abstract
Abstract A retainer case accommodating an air bag and consisting of two separate parts, one being an open end side part terminating in an open end of the retainer case and the other being an inflator-secured end side part secured to the vehicle body, the open end side part and inflator-secured end side part being fitted together to form the retainer case. The open end side part of the retainer case is made less rigid than the inflator-secured end side part. When an impact is applied to the retainer case from the passenger compartment side, the open end side part undergoes a deformation and thus absorbs the impact. A stem of the air bag is secured to the retainer case with its edge clamped between the fitted portions of the open end side part and inflator-secured end side part of the retainer case.
