Abstract: PURPOSE:To facilitate variation of the vibration absorbing characteristics by embedding an intermediate cylinder in a resilient member for vibration prevention provided between an inner and an outer cylinder, and discoupling this intermediate cylinder from the outer or inner cylinder to cause alteration of vibropreventive characteristics. CONSTITUTION:The inside surface of an inner resilient member 18 is adhered to the periphery of an inner cylinder 12 while the outside surface adhered to the bore of an intermediate cylinder 20. This intermediate cylinder 20 is fitted by pressure in another intermediate cylinder 22, and an outer resilient member 24 and an outer cylinder 14 are adhered to the outside surface. A pressure member 28 is in condition separate from the periphery of the intermediate cylinder 22 and both the inner and outer resilient members 18, 24 absorb vibration. This allows use of a resilient member in good accordance with the vibration characteristics to provide sure alteration of the vibration absorbing characteristics.
