In the airbag device in which the inflator is installed in the back of the airbag case, the airbag is folded and stored on the inlet side, and the blowing port is fixed to the inner wall of the inlet portion of the airbag case. The bag is unfolded centering on the air inlet, and only the back cloth on the air inlet side of the part that extends laterally from the left and right side extension lines of the air inlet is alternately folded inside and over, and then the above. The left and right back cloths and the front cloth following the fold-in portion are overlapped and folded so as to be folded toward the front cloth side to form a band-shaped body having a width substantially equal to the width of the blow-in port, and the band-shaped body is folded in a bellows shape.

Further, since the surface cloths are overlapped and folded on the front side, the above-mentioned belt-like body is formed into a belt-like shape extending in the front-rear direction with respect to the blowing port. Therefore, the airbag deploys in the two vertical directions at the initial stage of deployment, and slightly later, the central portion deploys, so that the airbag smoothly deploys into a predetermined shape. Also, since the left and right sides of the airbag in the unfolded state are folded in parallel with the surface cloth facing the blowing port, folding is facilitated, mechanical folding is possible, and bulkiness after folding is reduced. .
