A contacting part made of a thermoplastic resin composition is provided, which is characterized in that generation of squeaking noises that are generated when members rub against each other is remarkably reduced, that an effect of reducing squeaking noises is maintained without deterioration even when being placed under high temperatures for a long time, and further that not only heat resistance, impact resistance, and moldability are superior, but also safety at the time of collision is superior because of ductile fracture. The contacting part made of a thermoplastic resin composition [X] is composed of:
20 to 65 parts by mass of a rubber-reinforced vinyl resin [A]; and
35 to 80 parts by mass of a polycarbonate resin (provided that the total amount of [A] and [B] is 100 parts by mass);
wherein:
the rubber-reinforced vinyl resin [A] comprises a rubber-reinforced vinyl resin [A1] obtained by polymerizing a vinyl monomer [c1] in the presence of an ethylene -±- olefin rubber polymer [a1] having Tm (melting point) of 0°C or higher; and
the amount of the ethylene -±- olefin rubber polymer [a1] is 5 to 30% by mass based on 100% by mass of the thermoplastic resin composition [X]. |
