Abstract
The present invention provides a polyester elastomer resin composition which has excellent squeak resistance and abrasion resistance while maintaining mechanical properties. The excellent squeak resistance and abrasion resistance are caused by the fact that a lubricant contained in the polyester elastomer resin composition does not dissolve in water when a molded product is subjected to cleaning with water, and that the lubricant does not dissolve in a non-polar solvent (heptane) when the molded product is subjected to cleaning with the non-polar solvent (heptane). A polyester elastomer resin composition containing 0.1 to 5 parts by mass of polyoxytetramethylene polyoxyethylene glycol (B) per 100 parts by mass of a polyester elastomer (A) which comprises a hard segment and at least one soft segment, wherein the hard segment consists of a polyester containing an aromatic dicarboxylic acid and an aliphatic and/or alicyclic diol as constituent components, and wherein the soft segment is selected from the group consisting of aliphatic polyether, aliphatic polyester, and aliphatic polycarbonate.
