PURPOSE:To reduce the cost of molds and materials by a method in which projected are formed on the required portions of a surface material and bonded to the surface of unmolded flat base plate. CONSTITUTION:A surface material 20 is formed to have a predetermined shape and projected portions 21-23 or dappled patterns 26 are formed on the requireel rotations of the surface material 20. The surface material 20 is then bonded to the surface of a base material 2 in such a way as to form enclosed hollow portions 21a and 22a between the projected portions 21 and 22 of the surface material 20 and the base material 2, where the peripheral side of the material skin 20 is rolled up on the back side of the material 2 and bonded, or the peripheral side of the material 20 is fixed with tackers and fitted with retainers 15 through holes 5 from the back side. The door trim 1 is fixed to the door body by retainer, tapping screws, etc. By forming the projected hollow portions by the unmolded flat base plae and the surface material, the necessityh of forming an uneven surface in the base material can be eliminated and the costs of molding die and material can be reduced. |
