PROBLEM TO BE SOLVED: To improve pressure proof against a pressing load to a surface panel, facilitate assembly of various parts including an air bag case in a reverse side of the surface panel, and make a sharp edge hard to be generated in a burst surface of a burst opening part, and facilitate removal of an air bag at motor vehicle cassation time. SOLUTION: A frame unit 43 with edge part 431 in adhesion to a peripheral region of a burst opening part 30 of an interior trim cover 3 to reinforce it from a reverse side is arranged between the reverse side of the interior trim cover 3 and an air bag case (air bag supporter) 42, and reinforcing plate materials 31, 32 for the burst opening part extended according to expansion of an air bag 41 are connected by hinge extending margins 443, 444 to the edge part 431 opposed to the reverse side of the interior trim cover 3 of the frame unit 43. In this constitution, the air bag case 42 is separably connected to a part opposite to the interior trim cover 3 of the frame unit 43. |
