Abstract: A polyacetal resin composition which, when formed into a molded article, minimizes degradation caused by contact with a fuel. This resin composition contains 100 parts by weight of a polyacetal copolymer resin, 0.1-1.0 parts by weight of a hindered phenol-based antioxidant, 0.1-2.0 parts by weight of a divalent metal oxide, and 0.5-3.0 parts by weight of an alkylene oxide adduct of an alkylamine and/or an alkylene oxide adduct of an alkylene diamine Component contains magnesium oxide and/or zinc oxide, and component is one or more of general formulae (1) to (3). In these general formulae, X represents (C2H4O)m(C3H6O)nH, and m and n are each an integer of 0 or higher. In addition, R1 is an alkyl group having 12-18 carbon atoms, and R2 is an alkylene group having 2 or 3 carbon atoms.

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.
