To provide a vibration control bush capable of improving durability performance against input in a twisting direction without enlarging the size of the vibration control bush.SOLUTION: A vibration control bush comprises: an outer cylinder; an inner cylinder that is arranged on the inner peripheral side of the outer cylinder, and has both ends protruding from both ends of the outer cylinder; and an elastic body that elastically connects the outer cylinder and the inner cylinder. The outer cylinder includes, on one end side in an axial direction, an inclined part that is inclined with respect to the axial direction and extends outward in a radial direction. The inner cylinder comprises a stopper member protruding toward the inclined part on the outer periphery on the one end side in the axial direction. At least a part of the stopper member is made of an elastic material.SELECTED DRAWING: Figure 1
