Patent abstract
An inflator includes a plate-like retainer that is placed in a pressure container of the inflator for producing gas to be supplied to an airbag. At the center of inflator is formed a fitting section fitted to a tube placed in the pressure container. The tube separates an ignition source and a gas generation agent. At least one pressure release hole is provided on the outer side of the outer periphery of the fitting section. The retainer has a step formed at a portion where the outer periphery of the retainer is in contact with the filter. The retainer and inflator may have simple structures not affecting productivity and reliably preventing gas leakage between the retainer and a filter.
