Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an olefinic thermoplastic resin composition for molding an instrument panel integrated with an air bag cover suitable for integrally molding an air bag cover, which covers an opening part from which an air bag of a vehicle pops out, with the same material as that for the component of the instrument panel. SOLUTION: The composition has a specific initial flexural modulus of elasticity, suffers from no breakage in the Izod impact test, and comprises (A) 40-70 pts.wt. of a polypropylene resin, (B) 5-30 pts.wt. of an ethylene/propylene/(a non-conjugated diene) copolymer rubber having a Mooney viscosity ML1+4(100°C) of 20-70, (C) 5-30 pts.wt. of an ethylene/propylene/(a non-conjugated diene) copolymer rubber having a Mooney viscosity ML1+4(100°C) of 90-180, (D) 5-30 pts.wt. of an ethylene/octene copolymer having an MFR of 1-50 g/10 min, the total amount of the components (A), (B), (C) and (D) being 100 pts.wt., and (E) 1-15 pts.wt. of talc.
