PURPOSE:To absorb vibration in a direction other than an axial direction by partitioning a liquid chamber into small liquid chambers and connecting there chambers, making a shaft pass through the partition part, and providing a lateral vibration absorbing means in between said partition part and said shaft. CONSTITUTION:Vibration at the time of operating an engine is absorbed by the inner friction of upper and lower elastic bodies. Also, when a shaft 30 is vertically moved due to vibration, upper and lower liquid chambers 28A, 28B are expanded and contracted, and the vibration is absorbed by the passing resistance of liquid which passes through an orifice 13. In order to cope with a lateral vibration from the engine, the shaft 30 and a base plate 12 are relatively moved in the right and left directions. Thereby, an elastic body 46 is elastically deformed causing one of a pair of recessed parts 50 formed in a lateral vibration absorbing means 40 to be contracted while the other to be expanded. Thereby, the vibration can be absorbed by resistance which is provided when liquid in the contracted side of the recessed part 50 is moved to the other recessed part 50 through a groove 52. |
