PROBLEM TO BE SOLVED: To provide: a vibration-proof rubber composition that can improve ozone resistance (weatherability) and crack growth resistance of a vibration-proof rubber, and that can lower the dynamic-to-static modulus ratio; and the vibration-proof rubber.SOLUTION: A vibration-proof rubber composition includes, in a rubber component: a conjugated diene polymer; a conjugated diene compound-nonconjugated olefin copolymer; and a nonconjugated diene compound-nonconjugated olefin copolymer containing an ethylene-propylene-diene rubber. |
