A polyacetal resin composition comprising 30-90% by weight of polyacetal copolymer (A) having a melt index of less than 1.0 g/10 min. and 70-10% by weight of polyacetal copolymer (B) having a melt index of 1.0-100 g/10 min., both melting points of (A) and (B) being 155°-162° C., or a difference in melting point between (A) and (B) being not less than 6° C., has distinguished toughness and creep resistance. |
