(57) [Problem] To provide an anti-vibration rubber composition satisfying both anti-vibration characteristics and fatigue characteristics. SOLUTION: (A) A cis-1,4-bond content obtained by polymerizing a conjugated diene-based compound using a rare earth-based catalyst is 90% or more, and a 1,2-bond and a 3,4-bond content are obtained. 5% to 100 parts by weight of a conjugated diene-based polymer having a weight average molecular weight (Mw) and a number average molecular weight (Mn) of 3.5 or less; Rubber, at least one rubber selected from the group consisting of diene rubbers other than component (A) and olefin rubbers; 0 parts by weight [however, (A) + (B) = 100 parts by weight]. |
