<p>PURPOSE:To prevent an air bag, when it is inflated, from tearing passing through a thin thickness part of a cover. CONSTITUTION:In a part in the vicinity of the terminal end part of a thin thickness part 7a provided for guiding a tearing break, a through hole 10 or the like is provided in order to decrease rigidity over a surface direction. When the tearing break leads to the terminal end of the thin thickness part 7a, by deforming a part of this through hole 10 in the surface direction, force in a tearing break direction, applied to the thin thickness part 7a, is reduced.</p> |
