Engine vibration may also be input from other sources. In order to effectively prevent vibration transmission in such a case, it is necessary to optimally set the spring constant of the thick rubber elastic wall in the vertical and horizontal directions of the device. However, because each part of a conventional thick rubber elastic wall deforms in a complicated manner in response to vertical or horizontal vibration input, it has been difficult to determine its spring constant.

により決定される。[Operation and Effect] When vibration is input from the vertical direction in the figure, the thick rubber elastic wall 2 deforms in the vertical direction, and the sealing liquid from the liquid chamber A flows through the throttle hole 11 to the liquid chamber B.
Vibration damping occurs due to large flow resistance. In this case, the rubber elastic wall 2 has a surface 2
As for the portion 21 between a and surface 5b, the vibration force acts only in the compression direction, so it hardly deforms.
Only the portion 22 between the surface 5a and the side plate 4 is deformed by the vibration force in the shear direction, and the spring constant KC of the device at this time is determined by the shear elastic force of this portion 22. In response to vibration input in the left and right direction, the portion 22 receives the vibration force only in the compression direction and does not deform, but only the portion 2 undergoes shear deformation, and the spring constant KS of the device in this case is equal to the shear elasticity of the portion 21. Determined by power.

It can be prevented.

ことがある構造体との干渉が避けられる。 When excessive vibration is input from the vertical direction, the thick rubber elastic body 2 is deformed vertically significantly, but deformation beyond the predetermined interval d1 causes the edge 51 of the reinforcing plate 5 to deform.
This is prevented by a contacting the surface of the partition plate. This prevents fatigue of the rubber elastic body 2, and also avoids interference with structures that may be provided on the inner circumference of the partition plate 1.
