A rubber composition including (i) a partially hydrogenated unsaturated nitrile-conjugated diene copolymer having an iodine value not larger than 120, (ii) an ethylene-propylene copolymer and (iii) a material selected from an ethylene-vinyl acetate copolymer, an acrylic rubber and a halogenated butyl rubber. The rubber composition prodides a vulcanized rubber having an improved constant-elongation fatigue performance, as well as balanced thermal resistance, oil resistance and other properties.
