An airbag of the vehicles controlling amount of the supplied gas inside cushion by using the amplitude difference of the vent hole, and selectively tear a part of the middle barrier at least when the prescribed pressure is exceeded. The direction of development or the evolution shape of cushion can be variously diversified. As to the airbag of the vehicles classifying the cushion internal space with the middle barrier(20), the cushion(10) includes pads(12,14) taking shape the outer shape and the middle barrier which is arranged between pad and classifies the internal space of pad. The middle barrier has a plurality of vent holes which have different area respectively, and the pad is fixed through the sewing line(30). The break line(40) which selectively generates to be torn in the prescribed input or greater is the middle barrier.
