The object is to provide an airbag apparatus, having a configuration in which an amount of gas introduced into an airbag is varied by opening vent openings by shifting a closing member, for preventing gas generated by a gas generator from leaking through the vent openings when the closing member is closed. In order to achieve this object, a base (12b) of an airbag (12) is clamped between a heat shield plate (16) and a retainer bottom (10a). The retainer bottom (10a) has gas vent openings (30) thereon. The base (12b) of the airbag (12) forms a meltable layer (12a) covering the vent openings (30). The heat shield plate (16) has openings (32), for allowing gas to flow out, so as to be in line with the corresponding vent openings (30). A closing member (20) has a plurality of openings (34) thereon, for allowing the gas to flow out, in the longitudinal direction at the same disposing interval as that of the vent openings (30). In a normal state (i.e., when the airbag (12) is not inflated), the openings (34) are positioned so as to be out of line with the vent openings (30) . <IMAGE> |
