A rivet 28 is fitted into the hole 25 to serve as a plug for the hole 25. The outer circumferential surface of the outer cylinder I6 at the portion where the rivet 28 is fitted has a flat plate shape as shown in FIG.

It is divided into a lower liquid chamber 6A and a lower liquid chamber 26B. This partition wall 3
A disk-shaped core material 32 made of resin or metal is buried and fixed in the hole 0 by vulcanization adhesive. The upper liquid chamber 26A and the lower liquid chamber 26B are each formed continuously over the entire circumferential area.

The inner tube 12 is fitted and inserted into the circular hole 32A, and the core material 32 and the inner tube 12 are fixed. Further, a groove 32B is formed on the outer peripheral surface of the core material 32 in the front-rear direction (in the direction of arrow B in FIG. 2) to prevent the tip of the rivet 28 from coming into contact with it. Therefore, by preventing damage to the rivet 28, liquid leakage from the liquid chamber 26 can be prevented. The outer peripheral surface of the core member 32 in the left-right direction (direction of arrow C in FIG. 2) is in contact with the inner peripheral surface of the outer cylinder 16.

た場合には比較的高い剛性比を有する。Further, the outer circumferential surface of the partition wall 30 in the front-rear direction does not come into contact with the inner circumferential surface of the outer tube 14, and a restricted flow path 34 is formed between the outer circumferential surface of the partition wall 30 and the inner circumferential surface of the outer tube 16. This allows the upper liquid chamber 26A and the upper liquid chamber 26B to communicate with each other. As shown in FIG. 2, the restricted flow passages 34 are formed on opposite sides of the axis of the inner cylinder 12, respectively. Therefore, when horizontal vibration in the longitudinal direction (direction of arrow B) that connects the restricted flow path 34 and the axis of the inner cylinder 12 is applied to the outer cylinder 1G, the partition wall 30 is easily deformed, and the partition wall 30 differs by 90 degrees from this. Restricted flow path 3
When horizontal vibration (in the direction of arrow C) is applied from the left and right direction where the outer cylinder 16 and the partition wall 30 in which the partition wall 4 is not provided are in contact with each other, the outer cylinder 16 has a relatively high rigidity ratio.
次に本実施例の作用を説明する。Next, the operation of this embodiment will be explained.
防振装置10の外筒16を自動車のシャシへ、内筒12
を自動車のボディへ取り付けた場合の作用について説明
する。The outer cylinder 16 of the vibration isolator 10 is attached to the chassis of the automobile, and the inner cylinder 12 is attached to the chassis of the automobile.
The effect when attached to the body of a car will be explained.

ルが流れ、そのときの粘性抵抗によって減衰が得られる
。しかも、本実施例において使用されているシリコンオ
イルは高粘性流体のため広い範囲の周波数で減衰を得る
ことができる。In response to the vertical vibration of the vibration isolator 10, the partition wall 30 vibrates vertically as the inner cylinder 12 vibrates in the vertical direction. For this reason, the upper liquid chamber 26A and the upper liquid chamber 26B divided by the partition wall 30 expand and contract, so silicone oil flows into the restricted flow path 34, and damping is obtained by the viscous resistance at that time. Moreover, since the silicone oil used in this embodiment is a highly viscous fluid, damping can be obtained over a wide range of frequencies.
また、防振装置10の水平方向(前後方向)の振動に対

In addition, the damping in the vertical direction, longitudinal direction, and horizontal direction in this example is shown in Fig. 5 (A), (
It is represented by the graphs of B) and (C).

縮が円滑になるため高い減衰を得ることができる。When the vibration isolator 10 of this embodiment is attached to an automobile suspension component, the rigidity in the front-rear direction and the left-right direction are different in order to ensure stability of maneuverability. Therefore, in the direction of high rigidity, the vibration isolator 10 makes a part of the outer circumferential surface of the partition wall 30 come into contact with the outer cylinder 16 to increase the rigidity. Moreover, since the partition wall 30 is slidable in the vertical direction, the rigidity in the vertical direction is increased, and the upper liquid chamber 26A and the upper liquid chamber 26B can be expanded and contracted smoothly, so that high damping can be obtained.

Moreover, since the liquid chamber expands and contracts in the vertical direction smoothly, it has the effect that high damping can be obtained.
