Case member of airbag device, airbag device, method of manufacturing airbag device, and apparatus for manufacturing airbag device

摘要

A light-weight and inexpensively-manufacturable case member of an airbag device is provided. The case member includes an inner portion integrally formed with an edge portion of an opening portion of a housing portion configured to internally hold a folded airbag and an inflator. A lid is fixed to a housing portion at a position where the lid at least partially covers the airbag housed in the housing portion. The opening portion is covered by an outer portion. Thus, a light-weight case member in which the inflator and the folded airbag are housed in the housing portion and covered by the lid can be manufactured inexpensively, without integration of a separately provided housing portion and lid or fixing the airbag or the inflator using an additional component.
