PURPOSE:To obtain excellent vibration absorbing characteristics by forming a damper of the vulcanized material of rubber compound having partial hydroxide unsaturated nitrile-conjugate diene system copolymer whose conjugate diene unit part is hydrogenized above 95% as rubber component. CONSTITUTION:A damper is formed of the vulcanized material of rubber compound having partial hydroxide unsaturated nitrile-conjugate diene system copolymer, which has AN quantity of 35-45% and conjugate diene unit part hydrogenized above at least 95%, as rubber component. Thus a rubber damper which is excellent in anti-collapse, anti-wear and anti-heat aging can be obtained. |
