PROBLEM TO BE SOLVED: To provide a rubber composition for a high attenuation rubber bearing, with which temperature dependence of a shear modulus is improved and lowering of a coefficient of elasticity after repeated deformation is suppressed without deteriorating attenuation performance, and to provide a high attenuation rubber bearing using the same.SOLUTION: A rubber composition for a high attenuation rubber bearing includes a rubber, silica, and a petroleum resin, and further includes an alkylsilane represented by formula:(R-O)-Si-R(in formula, Ris a 1-3C alkyl group, Ris an alkyl group, and m is 1, 2, or 3) and/or a polyoxyalkylene glycol. A high attenuation rubber bearing is obtained by alternately laminating the rubber composition for the high attenuation rubber bearing and a hard plate. |
