PROBLEM TO BE SOLVED: To provide a polyacetal resin material improved particularly in sliding characteristic, while keeping inherent properties of polyacetal resin, such as excellent appearance, rigidity, heat stability, etc. SOLUTION: This polyacetal copolymer is obtained by copolymerizing 100 pts.wt. trioxane (A), 0.01-40 pts.wt. polysiloxane compound (B) having at least a cyclohexene oxide group, and 0-20 pts.wt. cyclic ether compound (C) capable of copolymerizing with trioxane.
