An anti-vibration device (1, 10), comprising: a pair of anti-vibration rubbers, each having: an outer cylinder connected to any one of a vibration generating body and a vibration receiving body by means of a bracket member and provided with a first flange portion formed on an end portion of an outer side of the outer cylinder in an axial direction to protrude toward an outer side in a radial direction; an inner cylinder connected to the other of the vibration generating body and the vibration receiving body by means of a plate member and disposed at an inner side of the outer cylinder; and a main body rubber disposed between the outer cylinder and the inner cylinder, wherein the pair of anti-vibration rubbers is connected to the bracket member by interposing the bracket member between both sides of the pair of first flange portions in the axial direction so that the inner ends of the pair of anti-vibration rubbers in the axial direction are opposite to each other, and a pair of plate members respectively disposed at outer sides of the pair of main body rubbers in the axial direction is pushed to the inner side in the axial direction by means of a coupling member passing through one pair of the inner cylinders so that the pair of anti-vibration rubbers is interposed between both sides in the axial direction by means of the plate members, wherein a first stopper rubber made of a rubber material having a hardness equal to or greater than that of the rubber material of the main body rubber is fixed to any one of an inner peripheral surface of the outer cylinder and an outer peripheral surface of the inner cylinder while keeping a gap in the radial direction between the inner peripheral surface of the outer cylinder and the outer peripheral surface of the inner cylinder, wherein a second flange portion protruding toward the inner side in the radial direction is formed at an end portion of an inner side of the outer cylinder in the axial direction, and wherein the first stopper rubber is fixed to the second flange portion to support the main body rubber from the inner side in the axial direction and protrudes toward the inner side in the radial direction more than the inner peripheral edge of the second flange portion. a pair of anti-vibration rubbers, each having: an outer cylinder connected to any one of a vibration generating body and a vibration receiving body by means of a bracket member and provided with a first flange portion formed on an end portion of an outer side of the outer cylinder in an axial direction to protrude toward an outer side in a radial direction; an inner cylinder connected to the other of the vibration generating body and the vibration receiving body by means of a plate member and disposed at an inner side of the outer cylinder; and a main body rubber disposed between the outer cylinder and the inner cylinder, an outer cylinder connected to any one of a vibration generating body and a vibration receiving body by means of a bracket member and provided with a first flange portion formed on an end portion of an outer side of the outer cylinder in an axial direction to protrude toward an outer side in a radial direction; an inner cylinder connected to the other of the vibration generating body and the vibration receiving body by means of a plate member and disposed at an inner side of the outer cylinder; and a main body rubber disposed between the outer cylinder and the inner cylinder, wherein the pair of anti-vibration rubbers is connected to the bracket member by interposing the bracket member between both sides of the pair of first flange portions in the axial direction so that the inner ends of the pair of anti-vibration rubbers in the axial direction are opposite to each other, and a pair of plate members respectively disposed at outer sides of the pair of main body rubbers in the axial direction is pushed to the inner side in the axial direction by means of a coupling member passing through one pair of the inner cylinders so that the pair of anti-vibration rubbers is interposed between both sides in the axial direction by means of the plate members, wherein a first stopper rubber made of a rubber material having a hardness equal to or greater than that of the rubber material of the main body rubber is fixed to any one of an inner peripheral surface of the outer cylinder and an outer peripheral surface of the inner cylinder while keeping a gap in the radial direction between the inner peripheral surface of the outer cylinder and the outer peripheral surface of the inner cylinder, wherein a second flange portion protruding toward the inner side in the radial direction is formed at an end portion of an inner side of the outer cylinder in the axial direction, and wherein the first stopper rubber is fixed to the second flange portion to support the main body rubber from the inner side in the axial direction and protrudes toward the inner side in the radial direction more than the inner peripheral edge of the second flange portion.
