A cylindrical anti-vibration bushing is disposed inside the holding part 41 , and the anti-vibration bush joins the outer periphery of the cylindrical anti-vibration rubber body 3 to the inner circumference of the outer cylinder 1 , and connects the outer periphery of the cylindrical anti-vibration rubber body 3 to the inner circumference of the outer cylinder 1 . An inner cylinder 2 that connects the vibrating body is buried therethrough. The outer cylinder 1 is made of synthetic resin such as nylon, and is press-fitted into the holding part 41 of the holder 4.
