Abstract
An air bag door construction in which the air bag develops smoothly and securely, the skin can be easily produced. The skin is formed by a mold including an endless and annular wall provided on a molding surface to be inclined relative to the molding surface. A groove portion of the skin formed by the wall is cut at a bottom portion to separate the skin into a general portion and a door portion which are made flush with each other. When the surfaces of the general portion and the door portion are flush the gap between the general portion and the door portion can be narrowed, and gap on the surface is narrowed. When the skin is disposed in the mold for foam forming, the skin can position the general portion and the door portion in the desired position easily, and will not scatter a skin chip in the development of the air bag.
