(57) [Problem] To improve the weather resistance (light) stability and thermal stability of a polyacetal resin and suppress the generation of formaldehyde. SOLUTION: The weather (light) stabilizer is 0.01 to 5 parts by weight, and the inhibitor is 0.0 with respect to 100 parts by weight of a polyacetal resin. About 1 to 10 parts by weight is added. The inhibitor can be selected from urea, urea derivatives and amidine derivatives. Urea derivatives include N-substituted ureas, urea condensates, and ureido compounds (acyclic ureides, cyclic ureides, or metal salts of cyclic ureides). Amidine derivatives include acyclic or non-melamine cyclic amidines and the like. An antioxidant, a colorant, a nitrogen-containing compound, or the like may be added to the polyacetal resin. |
