PROBLEM TO BE SOLVED: To provide a polyacetal resin composition excellent in secondary shrinking property and resistance against repeated impacts after ageing. SOLUTION: The polyacetal resin composition contains, based on 100 parts by mass of a polyacetal resin (A), 0.01 to 0.3 part by mass of dihydrazide carboxylate (B), polyethylene glycol (C) having a number average molecular weight of 300 to 10,000, of 2 to 20 times of parts by mass based on the dihydrazide carboxylate (B), and 0.01 to 2 parts by mass of a hindered phenol-based antioxidant (D).
