PROBLEM TO BE SOLVED: To provide a technique of improving heat life of a polyacetal resin molding on which a grease composition is applied.SOLUTION: A polyacetal resin composition including (A) 100 pts.mass of a polyacetal resin, (B) 0.10-0.25 pt.mass of a hindered phenol-based antioxidant, (C) 0.01-0.10 pt.mass of at least one metal compound selected from an alkali metal salt of a fatty acid, an alkali metal oxide, an alkaline earth metal salt of a fatty acid and an alkaline earth metal oxide, and (D) 0.01-0.10 pt.mass of a nitrogen-containing compound. A polyacetal resin molded product is obtained by molding the polyacetal resin composition and is used by being brought into contact with a grease composition containing an organic molybdenum compound. |
