PURPOSE:To cut off and attenuate engine vibration for high-speed running by installing a recessed pot on the inside of an outer tube on the extension of a stopper and thrusting the stopper into this recessed pot at a preset small gap. CONSTITUTION:A stopper 11 which moves outward from an inner tube 1 to an outer tube 2 along the vibration direction is provided on the inner tube 1 in a liquid chamber 4. A recessed pot 12 is installed on the inside of the outer tube 2 on the extension of the stopper 11. The stopper 11 is thrust into the recessed pot 12 at a preset small gap. When the recessed pot 12 and a mass body 14 are adequately arranged, the rise of the dynamic spring constant can be suppressed against the frequency up to about 350Hz at the maximum. Engine vibration can be cut off or attenuated for high-speed running. |
