However, as shown in FIG. 2, the structure of the air bag case 5 used in the air bag attaching device having such a structure has a large number of transparent members on the peripheral surface of the air bag case 5. The holes 12 are bored at intervals of the plover,
For example, when the vehicle body is running, a through hole 12 is provided to alleviate the impact force on the head when the occupant hits the head against the instrument panel in a collision such that the airbag device does not work. However, since the large number of through holes 12 are arranged at a puddle interval, the rigidity of the airbag case 5 in the generatrix direction is weak, and the stopper 10 is broken when the detonator explodes. It is conceivable that the airbag case 5 has been deformed previously and it is difficult to achieve the smooth opening of the deployment door 9.

In order to increase the rigidity of the air bag case 5, particularly in the generatrix direction, a large number of through holes 12 are formed in the circumferential surface of the air bag case 5 as shown in FIG. It has been proposed to align the
In this case, the rigidity of the airbag case 5 in the generatrix direction is increased as compared with the airbag case 5 shown in FIG.
When the detonator explodes, the airbag case 5 is less likely to be deformed before the stopper 10 is broken, and thus the certainty of the opening operation of the deployment door 9 is enhanced.
Due to the increased rigidity of the airbag case 5, when an occupant hits his / her head against the instrument panel when the airbag device is not in operation, the impact absorption by the airbag case 5 is poor and the regulation value cannot be satisfied. There was a problem.
