PROBLEM TO BE SOLVED: To provide sliding parts which retain excellent mechanical characteristics, moldability and the like inherent to polyacetal resin and also have much better sliding characteristics. SOLUTION: The sliding parts are composed of a polyacetal resin composition incorporating, based on (A) 100 pts.wt. of a polyacetal resin, (B) 0.05-20 pts.wt. of a lubricant which assumes a liquid at 200°C, and (C) 1-20 pts.wt. of a core-shell polymer having a core of a rubbery polymer and a shell of a glassy polymer consisting of a vinyl copolymer having an oxygen-containing polar group. The sliding parts exhibit superior sliding characteristics by allowing the surface of the molded articles of the sliding parts to be delustered and the contact area at the time of sliding to be reduced.
