Abstract
An air bag cover is made of thermoplastic resin and covers an air bag. A plurality of holes are provided with the air bag cover continuously and a breakable portion is provided which severs upon the inflation of the air bag. The surface side of the breakable portion is processed by a heating process, so that protrusions which partially plug the holes are formed on the inner circumferential surface of the holes on the surface side.
