PURPOSE:To provide a vibration control device, for which possibility of liquid leak due to loosening of a rivet is eliminated by forming a hole part for injecting fluid into a liquid chamber in a specific position from the part of an outer cylinder, to which a stopper member is opposed, to around the outer periphery of the outer cylinder, and by sealing the hole part with a seal member. CONSTITUTION:An inner cylinder 12 and an outer cylinder 14 are coaxially provided, and the inner cylinder 12 is connected to a vibration generating part such as an automobile engine, while the outer cylinder 14 is connected to a vibration receiving part such as a car body. An elastic body 18 made of rubber material and the like is suspended between the outer cylinder 14 and the inner cylinder 12, and a contracted diameter part 22 is provided on the center part in the axial direction of the elastic body 18. A space part surrounded by the outer cylinder 14 and the contracted diameter part 22 becomes a liquid chamber 24, and a viscous fluid 26 is sealed therein. Stoppers 28 are provided in a protruded manner on both sides of the inner cylinder 12. The front end sides are opposed to the inner circumferential side of the outer cylinder 14. A hole part 40 is provided on a position 90 deg. different from the part of the outer cylinder 14, to which the stopper 28 is opposed, and a rivet 42 is inserted into the hole part 40. The stopper 28 is not abutted on the rivet 42. |
