る。2. Description of the Related Art An airbag as described above is formed by, for example, superposing two circular cloths, an inflator-side cloth and an occupant-side cloth, and stitching the outer peripheral edges thereof. An opening into which the head of the inflator is inserted is formed substantially at the center of the base fabric on the inflator side.
