PURPOSE:To make even a lateral vibration adsorbable without fail, by producing a main elastic body with a low loss material but producing an auxiliary elastic body, receiving such a vibration as being directed to right angle with a vibro- absorbing direction of the main elastic, respectively, the other way. CONSTITUTION:With a partition plate 46 being held in between a cylinder body 42 and a base plate 10, a liquid chamber 24 is formed in space between the cylinder body 42 and a main elastic body 16, while a vibration plate 60 is attached to a circular hole 58 formed for the partition plate 46 and a disc 48, and in time of high frequency oscillations, it produces some vibrations which absorbed by a volumetric variation in the liquid chamber 24. An auxiliary elastic body 40 is installed in a space between a connecting part 54 of a top plate 20 and a block 56 being tightly attached to an outer circumference of the cylinder body 42, and the main elastic body 16 is produced with a low loss material while the auxiliary elastic body 40 with a high loss material, respectively, whereby not only vibrations in an arrow P direction but also those in an arrow Q direction are absorbable. |
