ことによって性能保証が困難になるという問題がある。By the way, in the case of the mechanical type using the rotating member, the structure is complicated, the number of parts is large, and it is difficult to secure durability and sealing property in the rotating portion of the rotating member. Therefore, there is a problem that the performance change during use becomes large. On the other hand, in the case of the electric type, not only the structure is complicated and the number of parts is large, but since the magnetic fluid is used as the working fluid, the performance changes with temperature change and the change with time of the working fluid. When it occurs, there is a problem that performance guarantee becomes difficult.

題を解決するものである。In addition, since the vibrating portion such as the bellows is in the working fluid, the fluid resistance associated with the vibration of the vibrating portion increases, and the required driving power consumption increases and sealing becomes difficult. Therefore, the present application solves such a problem.

A second connecting member, a rubber block provided between the two members, and a liquid chamber formed by at least a part of the rubber block are provided, and the liquid chamber is partitioned into a plurality of orifices. In the one communicating with the passage, a part of the wall forming the liquid chamber of the rubber block is used as a hydraulic pressure control plate, and the hydraulic pressure control plate is provided inside or outside of the liquid chamber by a control means provided outside. It is characterized by movement control.

を小さくできる。The internal pressure of the liquid chamber can be adjusted by controlling the movement inside or outside the liquid chamber by the control means provided with the liquid pressure control plate outside, and as a result, the damping characteristic and the dynamic spring characteristic can be controlled. It will be possible. Moreover, since the hydraulic pressure control plate uses a part of the wall portion of the rubber block forming the liquid chamber,
Since the sealing property is improved, the structure is simplified, and the number of parts is reduced, the cost can be reduced. Further, since the hydraulic fluid only comes into contact with the surface of the hydraulic pressure control plate, which is the wall of the hydraulic chamber, the fluid resistance associated with the movement of the hydraulic pressure control plate becomes relatively small, and as a result, the force required for driving is reduced. Can be made smaller.

な性能保証ができる。At this time, if the control means is constituted by an external air control device, the internal pressure of the liquid chamber can be adjusted by air pressure or negative pressure, which simplifies the structure and allows the conventional mechanical type or electromagnetic type to be used. Unlike the above, there is no need to install a rotating part in the liquid chamber and it does not cause deterioration of the hydraulic fluid, so the sealability and durability are improved, and the performance changes significantly due to changes in the operating environment such as temperature. It can be made small and can guarantee reliable performance.

The dynamic spring constant can be changed by contacting and separating from the case member side, and a non-linear spring characteristic corresponding to the magnitude of the input vibration can be exhibited.
