ABSTRACT:
The present invention provides a polyacetal resin composition having excellent mechanical characteristics with reduced generation of formaldehyde. To 100 parts by weight of (A1) a polyacetal resin having substantially straight chain molecular structure, there are added 0.1-20 parts by weight of (A2) a polyacetal resin having a branched or cross-linked molecular structure, 3-200 parts by weight of (B) a glass-base inorganic filler, and 0.001 to 3 parts by weight of (C) a boric acid compound.
