As a result, an orifice that connects the pressure receiving liquid chamber and the sub liquid chamber to each other is formed.

An elastic body is arranged between the first mounting member and the second mounting member, and the liquid is sealed in the pressure receiving liquid chamber arranged on the inner peripheral side of the elastic body. The connecting member is caulked to one of these mounting members, and the outer peripheral side of the diaphragm formed integrally with the elastic body and extending to the outer peripheral side of the elastic body is fixed to this mounting member. Further, the auxiliary liquid chamber arranged between the elastic body and the diaphragm on the outer peripheral side of the elastic body is connected to the pressure receiving liquid chamber.

の結果、弾性体の変形及び液体の流動に伴って振動が減
衰され、振動受部側に振動が伝達され難くなる。Therefore, when the vibration is transmitted from the vibration generating side connected to any one of the mounting members, the pressure receiving liquid chamber expands and contracts as the elastic body deforms, and the pressure receiving liquid chamber and the pressure receiving liquid chamber. The liquid comes to flow between the auxiliary liquid chamber and the auxiliary liquid chamber. As a result, the vibration is attenuated due to the deformation of the elastic body and the flow of the liquid, and it becomes difficult to transmit the vibration to the vibration receiving portion side.

組み込みの際の自由度が高まることになる。Further, since the sub liquid chamber is arranged on the outer peripheral side of the elastic body, the pressure receiving liquid chamber and the sub liquid chamber are not arranged in series between the vibration generating portion and the vibration receiving portion. The total height of the anti-vibration device is reduced. Therefore, the degree of freedom in assembling the anti-vibration device in the vehicle is increased.

However, according to the present invention, the orifice forming member is connected to the outer peripheral side of the elastic body, and by caulking the orifice forming member and the mounting member, an orifice for connecting the pressure receiving liquid chamber and the sub liquid chamber to each other is formed.

Since it is not arranged, the total height of the vibration isolator can be further reduced. Therefore, the degree of freedom in assembling the anti-vibration device into the vehicle is further increased.

る。Next, the operation of the present embodiment will be described. When the engine, which is the vibration generating unit mounted on the top plate 18, operates, the vibration of the engine is transmitted to the elastic body 16 via the top plate 18. The elastic body 16 acts as a main vibration absorber, and can absorb the vibration by the vibration damping function based on the internal friction of the deformable elastic body 16. Along with this, the pressure receiving liquid chamber 2
6 expands and contracts, and the liquid flows between the pressure receiving liquid chamber 26 and the sub liquid chamber 30 via the orifice 28. And the sub liquid chamber 30
A pressure change occurs in the liquid inside, and the diaphragm 24 expands and contracts.

The effect can improve the anti-vibration effect. As a result, the vibration is attenuated due to the deformation of the elastic body 16 and the flow of the liquid, and it becomes difficult to transmit the vibration to the vehicle body which is the vibration receiving portion.

The secondary liquid chamber 30
Are provided on the outer peripheral side of the elastic body 16. In addition, the elastic body 16
By caulking the orifice forming cylinder 32 and the bottom plate 12 which are connected to the lower outer peripheral side of the pressure receiving liquid chamber 26 and the elastic body 1.
An orifice 28 is formed on the outer peripheral side of the elastic body 16 so as to communicate with the auxiliary liquid chamber 30 disposed on the outer peripheral side of the elastic body 6.

になる。Therefore, since the sub liquid chamber 30 and the orifice 28 are arranged on the outer peripheral side of the elastic body 16, the pressure receiving liquid chamber 26, the sub liquid chamber 30 and the orifice 28 are arranged in series between the engine and the vehicle body. Therefore, the total height H of the vibration isolation device 10 can be reduced. Therefore, the degree of freedom in assembling the vibration isolation device 10 into the vehicle is increased.

Further, the orifice 28 includes the orifice forming cylinder 32 and the bottom plate 1.
Since it is configured by being divided by 2, it is not necessary to use a separate diaphragm and a partition member for the liquid chamber, the number of parts is reduced, and the manufacturing cost of the vibration isolator 10 is reduced.
