In liquid, an elastic main body member, a partition member, and a diaphragm are inserted into an outer cylinder one by one, and the diaphragm is held down by a fixing ring and fixed by a claw. Then, the liquid adheres onto outer circumferential surfaces of the partition member and the diaphragm. Therefore, a first special seal for adhered liquid is provided in an elastic partition member of the partition member and also a second special seal for adhered liquid and a third special seal for adhered liquid are provided in the diaphragm, so as to provide a seal between each of the outer circumferential surfaces of the partition member and the diaphragm and the fixing ring, so that the adhered liquid is prevented from leaking outwardly as leaked liquid.

A fluid-filled vibration-damping device including: a first mounting member; a second mounting member; a main rubber elastic body elastically connecting the two mounting members; a fluid chamber whose wall is constituted by the main rubber elastic body at a portion and by a flexible film at another portion, the fluid chamber being filled with a non-compressible fluid; a fixation member being attached to an outer peripheral rim of the flexible film and being disposed inside or outside the tubular second mounting member such that the fixation member is superposed to the second mounting member in an axis-perpendicular direction; an insertion hole formed in the second mounting member and the fixation member; and a positioning member inserted through the insertion hole so as to relatively position the second mounting member and the fixation member at a scaling position by axial locking.

A structure of an active mount is provided. The structure includes a case with an interior that is divided into upper and lower fluid chambers, a sealed hydro fluid flows based on a volume change of the upper fluid chamber due to deformation of an insulator, and flow characteristics of the hydro fluid are varied when power is applied to a driver. The structure further includes a generator that produces electricity based on behavior of the insulator. The generator is disposed within the case and the electricity produced by the generator is applied to the driver. Additionally, the generator autonomously produces electricity based on engine behavior and is mounted within an engine mount and, thus, supply of electricity from the outside is not required.

The anti-vibration device (1) includes: an inner attachment member (11); an outer cylinder (12) that surrounds the inner attachment member; and elastic bodies (31, 32) that elastically couple the inner attachment member and the outer cylinder. The elastic bodies include: a pair of end elastic bodies (31) fitted in the outer cylinder; and a pair of intermediate elastic bodies (32) separately arranged on both sides of the inner attachment member and between the end elastic bodies. Covering members (17) that form liquid chambers (14a, 14b) between the covering members and the inner attachment member is arranged between the inner attachment member and the outer cylinder. An orifice passage that provides communication between the liquid chambers is formed between the covering members and the outer cylinder. The entire intermediate elastic bodies are formed of rubber material. The covering members surround the entire circumference of the inner attachment member from outside thereof in a radial direction and cause compressive deformation of the intermediate elastic bodies inward in the radial direction and inward in a circumferential direction.
