PURPOSE: To provide an interior molding having excellent cushioning and damping properties, a uniformed thickness of a foam used therein, by integrally molding an aggregate of a thermoplastic resin on a rear face of a composite which is obtained by sticking a skin material to a polypropylene resin foam having a specified value or higher of gel fraction. CONSTITUTION: An interior mold 1 for a vehicle consists of an aggregate 2, a polypropylene resin foam 3 having 46% or higher of gel fraction, and a skin material 4. These members are laminated and integrally molded. For the skin material 4, a clothlike material using natural and artificial fibers, a sheet consisting of a vinyl chloride resin, and a thermoplastic elastomer sheet are used. For the polypropylene resin, a polypropylene resin which contains 1-30wt.% ofα-olefin such as a propylene homopolymer, an ethylene, a butene-1 and is preferably copolymerized in a random, random block or block state is used. For the aggregate 2, a thermoplastic resin is used. |
