Claims

[Scope of utility model registration request]

In a bush including a cylindrical intermediate cylinder between a cylindrical inner cylinder and an outer cylinder, a first elastic body is provided across an outer circumferential surface of the inner cylinder and an inner circumferential surface of the intermediate cylinder, and A second elastic body is provided between the outer peripheral surface of the intermediate cylinder and the inner peripheral surface of the outer cylinder to form two liquid chambers. A stopper is provided between the inner cylinder and the intermediate cylinder to form a passage communicating between the chambers, and to move the intermediate cylinder with respect to the outer cylinder when relative movement occurs between the inner cylinder and the outer cylinder in the direction perpendicular to the axis. In a bush in which a cylindrical intermediate cylinder is arranged between a cylindrical inner cylinder and an outer cylinder, the outer peripheral surface of the intermediate cylinder and the inner peripheral surface of the outer cylinder are A first elastic body is provided across the inner cylinder, and a second elastic body is provided across the outer peripheral surface of the inner cylinder and the inner peripheral surface of the intermediate cylinder to form two liquid chambers. A stopper that forms a passage communicating the two liquid chambers in the second elastic body, and moves the intermediate cylinder with respect to the inner cylinder when relative movement occurs between the inner cylinder and the outer cylinder in the direction perpendicular to the axis. A liquid-filled bushing characterized in that a liquid-filled bushing is provided between the intermediate cylinder and the outer cylinder.
