To provide a polyacetal resin composition having an excellent corrosion inhibiting effect on metals, particularly reduced in the adverse effect on magnetic tapes or the like, and suitable for use in producing component parts of a magnetic tape cassette such as a reel hub or tape guide, 100 parts by weight of a polyacetal resin (A) is blended with 0.05 to 5 parts by weight of an antioxidant (B), 0.001 to 5 parts by weight of a specified nitrogen-containing compound (C), and 0.001 to 3 parts by weight of a boric acid compound. |
