An airbag includes two base cloths sewn together at their outer peripheries by a seam extending from a central portion to the outer periphery of the base cloths into a vortical shape. When gas is supplied from an inflator to a center aperture of one of the base cloth to inflate the airbag, load generated by gas pressure breaks the seam sequentially from the central portion to the outer periphery, preventing sudden deployment of the airbag in fore and aft directions at the initial stage of deployment, thereby enabling not only soft restraining of passengers but also sufficient restraining by deploying the airbag into a final shape that is flat in fore and aft directions upon completion of breaking of the seam. The seam comprises a plurality of bonding portions such that the inflation breaks each of the bonding portions sequentially.
