<P>PROBLEM TO BE SOLVED: To provide parts for contact made from a thermoplastic resin composition which have remarkably reduced creaking sound generated when parts are in friction, keep the creaking sound reducing effect even when being left under a high temperature for a long time, have superior heat resistance, impact resistance and moldability, and have superior margin of safety on collision by causing ductile fracture in the case of destruction. <P>SOLUTION: The thermoplastic resin composition [X] contains 20-65 pts.mass of a rubber-reinforced vinyl resin [A] and 35-80 pts.mass of a polycarbonate resin [B] (note that the sum of [A] and [B] is 100 pts.mass). The rubber-reinforced vinyl resin [A] is a rubber-reinforced vinyl resin [A1] obtained by polymerizing a vinyl monomer [c1] under the presence of an ethylene/α-olefin rubber polymer [a1], the Tm (melting point) of which is 0°C or below. The parts for contact made from the thermoplastic composition contains 5-30 mass% of the ethylene/α-olefin rubber polymer [a1] to the 100 mass% of the thermoplastic resin composition[X]. <P>COPYRIGHT: (C)2012,JPO&INPIT |
