PROBLEM TO BE SOLVED: To obtain a vehicle exterior part that is made of a synthetic resin compounded with a specific wollastonite, a specific rubbery polymer and an olefin-based wax, has good external appearance, excellent chemical resistance, fatigue characteristic and other properties, and is used for decorative door handles, etc. SOLUTION: This vehicle exterior part comprises (A) 100 pts.wt. of a resin composition composed of (i) 80-50wt.% of an aromatic polycarbonate resin and (ii) 20-50wt.% of a thermoplastic polyester resin composed of polyethylene terephthalate resin and polybutylene terephthalate resin at a formulation rate of (1:2) to (1:7) by weight, (B) 8-15 pts.wt. of wollastonite, (C) 1-30 pts.wt. of a composite rubber-based graft copolymer in which at least one kind of vinyl monomer is grafted in the composite rubber composed of a polyorganosiloxane rubber component and a polyalkyl(meth)acrylate rubber component in mutually entangled structure so that both the components can not be separated from each other, and (D) 0.02-5 pts.wt. of an olefin-based wax which contains carboxyl groups and/or carboxylic anhydride group. |
