Abstract: An automobile part comprising a polypropylene resin composition, the polypropylene resin composition comprising a propylene homopolymer (A1), an elastomer (B) and an inorganic filler (C) in specified proportions. The polypropylene homopolymer (A1) exhibits an MFR (230° C.) of 20 to 300 g/10 min, a ratio of position irregular units derived from 2,1-insertion or 1,3-insertion of propylene monomer relative to all propylene structural units, determined from a 13C-NMR spectrum, each of 0.05% or less, and an Mw/Mn, determined by GPC, of 1 to 3.

Abstract: A propylene resin composition comprising (A) a crystalline propylene block copolymer in an amount of 89 to 30% by weight, which has a specific content of a 23° C. n-decane-soluble component, said soluble component having a specific intrinsic viscosity [?]a as measured in decalin at 135° C., has a specific melt flow rate (MFR, 230° C., load of 2160 g), and has a specific isotactic pentad fraction of a polypropylene homopolymer portion as measured by 13C-NMR, (B) a crystalline propylene block copolymer in an amount of 5 to 25% by weight, which has a specific content of a 23° C. n-decane-soluble component, said soluble component having a specific intrinsic viscosity [?]b as measured in decalin at 135° C., has a specific melt flow rate (MFR, 230° C., load of 2160 g), and has a specific isotactic pentad fraction of a polypropylene homopolymer portion as measured by 13C-NMR, (C) an elastomeric polymer in an amount of 1 to 20% by weight, which has a melt flow rate (MFR, 230C, load of 2160 g) of 0.
