A vibration isolation rubber composition containing the following components (B) to (E) together with a rubber compound made of the following (A) is produced, which makes it possible to highly satisfy both heat resistance and the reduction of dynamic magnification factors. The vibration isolation rubber composition containing (A) a diene-based rubber containing natural rubber as a main component, (B) a filler, (C) a hydrazide compound, (D) a disulfide compound represented by General Formula (1), and (E) a sulfur-based vulcanizing agent.[In General Formula (1), a ring A and a ring B each indicate a nitrogen-containing heterocyclic group having 4 to 24 carbon atoms.] |
