PROBLEM TO BE SOLVED: To prevent occurrence of crack due to stress concentration in a boundary section of an outer peripheral end of an outer cylinder and a rubber part to improve durability by devising a structure of vibration control rubber composed of an inner cylinder, the outer cylinder, and the rubber part between both of them. SOLUTION: In this vibration control rubber composed of the inner cylinder 1, the outer cylinder 2 composed of a boss part 2A having a shaft axis along the direction of shaft axis P of the inner cylinder 1 and an outward facing flange part 2B along the radial direction of the inner cylinder 1, and the rubber part 3 provided among an inner peripheral face 4 of the boss part 2A, an outer face 4 of the flange part, and the inner cylinder 1 to integrate both cylinders 1, 2 mutually by vulcanization bonding, the rubber part 3 is formed so as to go around the outer periphery of the outward facing flange part 2B, and a chamfered part 10 is formed in a corner part 7 of a boundary part of the outer face 4 in the outward facing flange part 2B and an outer peripheral face 11.
