PROBLEM TO BE SOLVED: To provide an ethylene-acrylic rubber composition excellent in the balance of cold resistance and heat resistance, a vulcanizate thereof, a hose part, a sealing part and a vibration-damping part using the vulcanizate. SOLUTION: There are provided an ethylene-acrylic rubber composition excellent in the balance of cold resistance and heat resistance, a vulcanizate thereof, a hose part, a sealing part and a vibration-damping part using the vulcanizate by blending a specific polytetramethylene glycol with an ethylene-acrylic rubber. The ethylene-acrylic rubber is preferably a copolymer of ethylene and an alkyl acrylate which is an ester of a 1-8C alcohol and acrylic acid. COPYRIGHT: (C)2006,JPO&NCIPI
