The present invention relates to an air bag device for a vehicle comprising an inflator, an air bag, an air bag case for storing these and an air bag door, in which the air bag and the air bag door are attached to the air bag case by inserting a retainer bar in a shape of a locking bar from a retainer addingly brought into contact with the inner side of a side wall of the air bag case through engaging loop portions penetrating the side wall of the air bag case, the air bag door and the air bag, and in which the air bag and the air bag door are attached to the air bag case. In the above air bag device, by improving a structure of a support portion for supporting the retainer bar inserted through the loop portions, projections of the air bag case are reduced, compact formation and light weight formation of a module is achieved and mountability, strength and economic performance are promoted. As means therefor, the retainer is installed with support pieces for the retainer bar projected from base portions of the loop portions, elastically pressing the retainer bar to tip portions of the loop portions and pinching and supporting the retainer bar between the support pieces and the front end portions of the loop portions in the loop portions.
