PROBLEM TO BE SOLVED: To prevent the generation of scattered material with a breakdown of an interior side member and the exposure of the rough surface by providing a surface of an interior side member in the condition that it makes contact with a part to be broken of a door base material or in the nearly contact condition along a part to be formed with an opening of the interior side member. SOLUTION: In a surface material 30, a door base material 40 formed with a part 40T to be broken is integrally arranged with an interior side member 20 in a back surface of a part 20T, which is to be formed with an opening, of the interior side member 20 having the surface 31. A bottom surface of a recessed part 35 of the surface 31 and a part 40T, which is to be broken, of the door base material 40 are made to come close to each other in the nearly contact condition along the part 20T, which is to be formed with an opening, of the interior side member 20. As a result, at the time of expanding an air bag, only the part 20T to be formed with an opening of the surface 31 and the part 40T to be broken of the door base material 40 are appeared in broken parts T1, T2 of the interior side member 20, and exposure of other interior side member is prevented. |
