Abstract: A polyacetal resin composition makes it possible, when formed into a molded article, to minimize deterioration during contact with sulfur-containing fuel or an acidic detergent. The polyacetal resin composition contains (A) 100 parts by weight of polyacetal resin, (B) 0.1-1.0 parts by weight of hindered phenolic antioxidant, (C) 0.1-2.0 parts by weight of alkaline earth metal oxide, (D) 0.5-3.0 parts by weight of polyalkylene glycol, and (E) 0.01-1.0 parts by weight of polyvalent fatty acid full ester. This polyacetal resin composition minimizes reductions in the weight of a molded article even after the molded article has been immersed in sulfur-containing fuel.
