摘要: The present invention relates to interior parts of a car comprising a new propylene resin composition. The present resin composition has good molding abilities and a good balance of physical properties as well as a good appearance, lower gloss and scratch resistance. Specifically, the present invention relates to a molded article for interior parts of a car comprising a polypropylene resin composition comprising the following components; a crystalline homopolypropylene having MFR of 500 to 3,000 g/10 min.; a polypropylene consisting of a crystalline homopolypropylene and an ethylene-propylene copolymer rubber having 45 to 80% by mass of a ethylene content; a polypropylene consisting of a crystalline homopolypropylene and an ethylene-propylene copolymer rubber having 25% by mass or more to below 45% by mass of a ethylene content; and an ethylene-α-olefin copolymer rubber.
