Abstract
A bag-like airbag is folded into a substantially T-shape having a first developing portion which is continuous with an opening from which gas flows in and second developing portions extending fore-and-aft direction from an upper end of the first developing portion. Each of the second developing portions is folded into a bellows toward a prescribed point, thereby forming an aggregate. The aggregate is rotated, the first developing portion is wound around the aggregate, and the folded airbag is accommodated in an airbag accommodation portion of a retainer.
