PURPOSE:To lower dynamic stiffness as a mount in the range of high frequencies, and thereby make a damping effect much greater by constituting a dynamic damper of several elastic springs, and of a mass. CONSTITUTION:A dynamic damper 10 fitted onto a main chamber 7 is made up of the mass 12 supported by a dynamic damper guard 16, an upper coil spring 11 and a lower coil spring 13, and a gap is provided while being interspaced with an upper section within the main chamber in order that a much greater damping effect can be provided. When the natural frequency of the dynamic damper 10 is made to be less than 200Hz, the mass 12 oscillates in a reverse phase with respect to the direction of the motion of an insulator inner cylinder 1 while acting as the dynamic damper in the high frequency range of roughly 200 to 500Hz, so that high frequency vibration is thereby greatly damped. In addition, when the mass 12 provided for the upper section within the main chamber 7 oscillates via liquid, a much greater damping effect is produced, so that damping force can thereby be set arbitrarily.
