PROBLEM TO BE SOLVED: To provide a polyacetal resin composition that, when molded into a molded article, deteriorates minimally when contacting with fuel.SOLUTION: The resin composition of the present invention contains (A) a polyacetal copolymer resin of 100 pts.wt., (B) a hindered phenol-based antioxidant of 0.1 to 1.0 pts.wt., (C) bivalent metal oxide of 0.1 to 2.0 pts.wt., (D) an alkylene oxide additive of alkyl amine and/or an alkylene oxide additive of alkylene diamine of 0.5 to 3.0 pts.wt.. The (C) component preferably contains magnesium oxide and/or zinc oxide, the (D) component is preferably one or more kind selected from the general formulae (1) to (3). In the general formulae, X is represented by (CHO)(CHO)H, m and n is an integer of 0 or more. Ris an alkyl group having 12 to 18 carbon atoms and Ris an alkylene group having 2 to 3 carbon atoms. |
