<p>PROBLEM TO BE SOLVED: To provide a contact component made of a thermoplastic resin composition in which squeak sound generated upon rubbing of members is remarkably reduced, also, squeak sound reduction effect is maintained even if being placed at high temperature for a long time, further, having excellent heat resistance, impact resistance and moldability, and having excellent safety upon collision by ductile breaking even upon breaking.SOLUTION: Provided is a contact component made of a thermoplastic resin composition in which squeak sound is reduced being a thermoplastic resin composition [X] including: a rubber-reinforced vinylic resin [A] of 20 to 65 pts.mass; and a polycarbonate resin [B] of 35 to 80 pts.mass (where, the total of the [A] and the [B] is 100 pts.mass). The rubber-reinforced vinylic resin [A] includes: a rubber-reinforced vinylic resin [A1] obtainable by polymerizing vinylic monomers [c1] in the presence of an ethyleneα-olefinic rubber-like polymer [a1] having a Tm (melting point) of 0°C or higher, and a rubber-reinforced vinylic resin [A2] obtainable by polymerizing vinylic monomers [c2] in the presence of a diene rubber-like polymer [a2], and the total content of the ethyleneα-olefinic rubber-like polymer [a1] and the diene rubber-like polymer [a2] is 5 to 30 mass% with the thermoplastic resin composition [X] as 100 mass%.</p> |
