To facilitate manufacturing with high dimensional accuracy a cover of an airbag apparatus is provided with a door frame movable member and a door frame fixation member at a rear face of an interior panel, in which a door portion opens while the door frame movable member is lifted. When an inflator 14 is operated to blow out gas, a door frame movable member 32 is moved upward (lifted) by being pressed upward by an expanding airbag 12. The module cover 20 is burst along a tear line 22b and a door portion 24 is cut off and separated from the surrounding module cover 20. The door portion 24 is further moved upward together with the door frame movable member 32 and a tear line 22a of the door portion 24 is burst by being pressed by the airbag 12. The door portion 24 and each of the lining plate portions 32a, 32b start to open like a door being separated into two ways in the left and right directions as shown in FIG. 2, and the airbag 12 is expanded into a vehicle cabin. The door frame fixation member 34, the door frame movable member 32, and the module cover 21 are integrally formed by means of double-shot molding process (Fig. 1). |
