摘要：
A polyacetal resin composition which has improved friction-wear characteristics as compared with conventional polyacetal resin compositions and which is less restricted in counter sliding members and can conform to a wide range of friction-wear conditions. A polyacetal resin composition comprising 100 parts by weight of (A) a polyacetal resin, 0.1 to 10 parts by weight of (B) a polyethylene wax having a number average molecular weight of 500 to 15,000, 0.1 to 10 parts by weight of (C) a polyethylene resin having a number average molecular weight of 2×104 to 50×104, and 0.1 to 5 parts by weight of (D) a silicone oil having a kinetic viscosity at 25° C. of 50×104 cSt or more.
