Abstract

There is disclosed a polyacetal resin composition that has excellent slidability and abrasion resistance and makes it possible to propose molded parts free of problems such as abrasion and noises such as squeaking caused by abrasion even when used under high load and high sliding speed conditions even when the material of the partner sliding parts is any type of plastic or metal. The resin includes from 0.5 to 15 parts by weight of olefinic elastomer, from 0.1 to 5.0 parts by weight of fatty acid ester having at least 12 carbon atoms, and, if necessary, from 0.05 to 5.0 parts by weight of polytetrafluoroethaylene micropowder per 100 parts by weight of polyacetal resin.
