Description of the Related Art For example, a link is arranged between a wheel serving as a vibration generating portion and a vehicle body serving as a vibration receiving portion, and a vibration damping device serving as a bush is disposed at an end portion of the link. Has been done. Therefore, the vibration isolator absorbs vibrations generated between the road surface and the wheels and prevents the vibrations from being transmitted to the vehicle body.

When the vehicle travels and vibration is generated, the vibration is absorbed by the vibration damping function of the elastic body and the viscous resistance of the liquid in the liquid chamber, and the transmission of the vibration is blocked.

部内に圧入していた。In the conventional manufacturing of a vibration isolator, after forming an elastic body, an outer cylinder produced by pressing or the like is drawn and attached to the outside of the elastic body to provide a vibration isolator having a liquid chamber inside. Each was made and these were individually press fit into the ends of the links.

を特徴とする。According to a first aspect of the present invention, there is provided a vibration isolator comprising: a link which is connected to one of a vibration generating part and a vibration receiving part and which is integrally molded with resin; and a vibration generating part and a vibration receiving part. An inner cylinder connected to the other and arranged inside the end portion of the link, and arranged between the link and the inner cylinder so as to connect the link and the inner cylinder, and close to the outer circumference. An elastic body in which a reinforcing metal fitting is arranged, a liquid chamber in which at least a part of an inner wall is formed of the elastic body and liquid is sealed, and a link formed along the outer peripheral surface of the elastic body. A sealing member that is interposed between a joint surface with the reinforcing metal member and seals the liquid chamber.

【作用】請求項１に係る防振装置の作用を以下に説明す
る。The operation of the vibration isolator according to claim 1 will be described below.
【０００９】弾性体がリンクと内筒との間を連結し、振

と、弾性体が変形し、結果として弾性体の変形により振
動が減衰して、リンクあるいは内筒に連結される振動受
け部側に振動が伝達され難くなる。Since the elastic body connects between the link and the inner cylinder, and the inner cylinder or the link is connected to the vibration generating portion, when the vibration is transmitted from the vibration generating portion side to the inner cylinder or the link, the elastic body is elastic. The body is deformed, and as a result, the deformation of the elastic body attenuates the vibration, which makes it difficult to transmit the vibration to the vibration receiving portion side connected to the link or the inner cylinder.

され難くなる。Therefore, the liquid chamber expands and contracts in accordance with the deformation of the elastic body to cause a pressure change and flow of the liquid in the liquid chamber, and not only the deformation of the elastic body but also the pressure change of the liquid and the viscous resistance dampen the vibration As a result, the vibration is more difficult to be transmitted to the vibration receiving portion side.

At the same time, it is not necessary to press-fit the anti-vibration device having the outer cylinder into the link, which simplifies the assembling process and further reduces the weight of the anti-vibration device.

At this time, the sealing member serves as a cover to prevent vibration. It is possible to prevent the resin material from entering the gap in the device.
