Abstract

PURPOSE:To remarkably simplify manufacturing steps by employing an ornament member and two or more types of skin members as a skin material, and distinctly applying them simultaneously upon molding of a base material in a mold. CONSTITUTION:An ornament member 11 is first inserted between an upper mold 3 and a lower mold 2, and its edge is engaged with the styluslike protrusion 6 of a slide core 7 so disposed as to rise. Then, a skin member 12 laminated with a cushion layer 12b is so set on the lower face of a synthetic resin base 12a in a size covering substantially the mold 2. The upper mold 3 is moved down, the edge of the member 11 is pressed to the core 7 at the lower end of a pressed part 8 thereby to inject to pour a synthetic resin molding material 21a in cavity 4 between the member 11 and the mold 2 and between the member 12 and the mold 2. After it is semicured, a synthetic resin molding material 21b is injected to be poured in an air gap 13 formed by slightly moving down the core 7, a molding base material integrated with the material 21a is molded as a product.
