PURPOSE: To provide a polyoxymethylene resin composition having improved high-temperature sliding performance and suppressed generation of squeaking noise at high temperature. CONSTITUTION: This polyoxymethylene resin composition having remarkably suppressed high-temperature squeaking noise under high load is composed of (A) 60-99.89wt.% of a polyoxymethylene resin, (B) 0.1-20wt.% of an ethylene-α- olefin copolymer having a melting point of 40-80 deg.C and (C) 0.01-20wt.% of one or more substances selected from tetramethylene glycol-ethylene glycol copolymers and liquid ethylene-α-olefin random copolymers.
