ABSTRACT:
A gas generator for an air bag is provided which includes a housing having first and second outer shells each having a flange, a gas generation device disposed inside the housing and a gas jet portion for introducing a gas in the gas generation device into the air bag. The flanges of the first and second outer shells are fastened together by locally fastening the flange of the first outer shell and the flange of the second outer shell together with predetermined gaps therebetween. The flange portion has joint portions at which the flanges are attached to each other and contact portions formed between the joint portions at which the flanges are in mere contact with each other. The gas jet portion is formed of the contact portions. The contact portions are opened by buildup of gas pressure inside the housing after impact and the corresponding activation of gas generation device.
