A polyacetal resin composition is composed of a polyacetal resin and a polycyclic aromatic carboxylic acid hydrazide which may have a substituent. The polycyclic aromatic carboxylic acid hydrazide may be contained in an amount of 0.001-20 parts by weight per 100 parts by weight of the polyacetal resin. The polyacetal resin composition may further contain at least one element selected among antioxidants, heat resistance stabilizers, processing stabilizers, weathering (light resistance) stabilizers, impact strength modifiers, sliding property modifiers, coloring agents and fillers. With this resin composition, stability of the polyacetal resin can be improved, while suppressing generation of formaldehyde. |
