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&#xb0; 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 aC-NMR spectrum, each of 0.05% or less, and an Mw/Mn, determined by GPC, of 1 to 3.

Automobile part of polypropylene resin composition

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), or comprising a propylene block copolymer (A2) and an inorganic filler (C) optionally together with an elastomer (B), in specified proportions. The propylene homopolymer (A1), or the propylene homopolymer segment of the propylene block copolymer (A2) 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 aC-NMR spectrum, each of 0.2% or less, and an Mw/Mn, determined by GPC, of 1 to 3.
