One of the one mounting portion 1 and the other mounting portion 4 is connected to a support side such as a vehicle body of an automobile and the other is connected to a supported side such as an engine to elastically support the supported body such as the engine. While supporting and suppressing the input vibration mainly by the elastic deformation of the elastic body 8 and the flow resistance of the hydraulic fluid 15 passing through the orifice 14, the high frequency vibration (high frequency micro vibration) of a predetermined specific frequency is input. In this case, as shown by arrows A and B in FIG. 2, the hydraulic fluid 15 moves in and out of the first orifice 27 for high frequency vibration, and resonates, so that the absolute spring constant of the mount is suppressed to a low level. As a result, this high frequency vibration can be effectively absorbed and suppressed. Also, different frequency (such frequency is also predetermined) due to changes in vehicle speed or engine speed, etc.
When the high frequency vibration (high frequency slight vibration) is input, the working fluid 15 moves in and out of the second orifice 28 for high frequency vibration to resonate, as indicated by arrows C and D in FIG.
At this time as well, the absolute spring constant of the mount is suppressed to a low level, whereby this high frequency vibration can be effectively absorbed and suppressed. Therefore, from the above, it is possible to realize the "low dynamic spring" of the mount over a wide frequency range, and improve the damping characteristics or the vibration isolation performance of the mount.

ウントを提供することができる。When downward vibration (bounding direction) of a predetermined value or more is input to the liquid-filled mount having the above-described structure, the outward flange 16c of the stirring section 16 is inputted.
And the partition part 11 contact each other and the first stopper part 22
Is actuated, which stops the elastic body 8 from further elastic deformation. Further, when an upward (rebound direction) vibration of a predetermined value or more is input to the mount, the outward flange portion 16c of the stirring portion 16 and the inward flange portion 20c of the orifice member 20 are brought into contact with each other to make a first contact. The second stopper portion 24 is actuated, thereby stopping further elastic deformation of the elastic body 8. Further, when vibrations in the front-rear direction and the left-right direction (directions orthogonal to the bounding direction and the rebounding direction) of a predetermined value or more are input to the mount, the tubular portion 16a of the stirring portion 16 and the tubular portion of the orifice member 20 are shaped. The portion 20d abuts against each other to operate the third stopper portion 26, which stops the elastic body 8 from being further elastically deformed. Therefore, excessive elastic deformation of the elastic body 8 is limited in all directions, and damage to the elastic body 8 is substantially completely prevented. Therefore, in this sense, it is possible to provide a vibration-proof mount exhibiting excellent safety and durability.

が滑らかに作動する効果がある。When the first stopper portion 22 operates, the cushioning body 19 attached to the lower surface of the outward flange portion 16c of the stirring portion 16 exerts a cushioning action, and when the second stopper portion 24 operates. When the cushioning body 19 attached to the upper surface of the outward flange portion 16c of the stirring portion 16c exerts a cushioning action and the third stopper portion 26 operates, the outer peripheral surface of the cylindrical portion 16a of the stirring portion 16 is covered. The attached buffer body 19 has a cushioning effect. Therefore, from these facts, impact is unlikely to occur when the stoppers 22, 24, 26 are operated, and the stoppers 22, 24, 26 are not affected.
Has the effect of operating smoothly.
