PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition for a vehicle lamp fitting which is excellent not only in shock resistance, fluidity and weatherability but also in vapor deposition appearance and tapping strength upon fitting, especially excellent in tapping strength in low temperature environment.SOLUTION: A thermoplastic resin composition includes a graft copolymer (A) and a copolymer (B). The graft copolymer (A) is provided by performing graft polymerization of a monomer consisting of at least one kind selected from vinyl cyanide monomer, aromatic vinyl monomer, and other vinyl type monomer copolymerizable with the vinyl cyanide monomer, aromatic vinyl monomer and, regarding composite rubber existing in the graft copolymer, the number of particles of the composite rubber of which the circle-equivalent particle size is 150 nm or less is 50% or less of the whole composite rubber particles. The copolymer (B) is provided by copolymerizing aromatic vinyl monomer, vinyl cyanide monomer and, as necessary, other copolymerizable vinyl monomer. |
