POLYESTER ELASTOMER RESIN COMPOSITION
A polyester elastomer resin composition having excellent anti-noise properties and wear resistance that achieves sustained wear resistance over a long period of time; enables lubricants to bleed out even in a low-temperature environment, so that the effects of the lubricants are maintained; and further prevents the lubricants from being dissolved in water, even when a molded article is washed with water. The polyester elastomer resin composition comprises a polyester elastomer (A), an aliphatic amide compound (B), and a copolyether (C), wherein the polyester elastomer (A) comprises a hard segment and a soft segment, the hard segment comprising a polyester that comprises, as constituents, an aromatic dicarboxylic acid and an aliphatic and/or alicyclic diol, the soft segment being at least one member selected from aliphatic polyethers, aliphatic polyesters, and aliphatic polycarbonates; the copolyether (C) comprises two or more different types of alkylene units and has a number average molecular weight of 1500 to 5000; and the aliphatic amide compound (B) is present in an amount of 0.01 to 1 part by mass, and the copolyether (C) is present in an amount of 0.1 to 10 parts by mass, per 100 parts by mass of the polyester elastomer (A).
