Abstract

A polyoxymethylene (POM) resin composition which is used for a resin molded article having a superior sliding characteristic. The POM resin composition contains: (A) 100 parts by mass of a POM resin; (B) 0.01-1 parts by mass of a hindered phenolic antioxidant; (C) 0.05-1 parts by mass of a nitrogen-containing compound; (D) 0.5-10 parts by mass of a modified olefin polymer; (E) 0.01-5 parts by mass of an alkylene glycol polymer; (F) 0.1-20 parts by mass of calcium carbonate; (G) 0.1-10 parts by mass of a partial ester of a polyhydric alcohol; and (H) 0.1-10 parts by mass of an a-olefin oligomer. An ISO tensile test piece, which is obtained by injection molding at a die temperature of 90° C. and a cylinder temperature of 200° C., is crushed, Soxhlet extraction is performed for 3 hours at 70° C. using methanol, and the alkylene glycol polymer is measured. The weight of the alkylene glycol polymer is 0.001 wt % or less relative to 100 wt % of the test piece.
