Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a resin compsn. for molding an automobile side molding excellent in flexibility, dimensional stability, appearance, and economical efficiency and having low stickiness. and an automobile side molding. SOLUTION: This resin compsn. for molding an automobile side molding is prepared by compounding 77.92-81.94 wt.% propylene block copolymer (A), 9-11 wt.% ethylene elastomer (B), 9-11 wt.% talc having not higher than 3.0 μm average particle diameter (C), and 0.06-0.08 wt.% mol.wt. depressant. The block copolymer (A) contains a propylene homopolymer component and an ethylene/propylene copolymer component, and on intrinsic viscosity [η]PP of the homopolymer component and the critical viscosity [η]RC of the copolymer component are both 1.8-2.0 dl/g, and the weight ratio (WPP/WRC) of the weight of the homopolymer component WPP and the weight of the copolymer component WRC is 1.9-2.1. This automobile side molding is provided by molding the resin compsn.
