Thermoplastic resin composition for reduction of squeaking noises and structure of reduced squeaking noises

A structure of reduced squeaking noises which comprises at least two contacting parts assembled to come into contact with each other,

• wherein the at least two contacting parts are made of a thermoplastic resin composition [X] consisting of:
• a rubber-reinforced vinyl resin [A] obtained by polymerizing a vinyl monomer [b1] in the presence of an ethylene-α-olefin rubber polymer [a1] consisting of ethylene and an α-olefin having Tm (melting point) of 0° C. or higher;
• and
• a silicone oil, and
• wherein an amount of silicon derived from the silicone oil contained in the thermoplastic resin composition [X] is more than 0.03% by mass and not more than 0.15% by mass based on 100% by mass of the thermoplastic resin composition [X].
