取付ける際に使用される。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is characterized in that a pair of fluid hardeners formed in a 5-elastic body are separated by an orifice plate, and the orifices of the core orifice plate are all valved to control the flow of fluid inside the silkworm. Conventional technology related to a fluid-filled vibration isolator that efficiently transmits and completely damps vibrations by moving working fluid.This type of fluid-filled vibration isolator is used, for example, as an engine mount, and is used in vehicle bodies. Used when attaching to a frame.

うになっている。By the way, this fluid-filled vibration isolator is formed of an elastic body filled with 10,000 fluids, and the other fluid chamber is provided within a diaphragm made of an elastic body, and these two fluid chambers are separated by an Oriswiss plate. The oriswiss plate and the annular frame plate supporting the diaphragm are fixed to a cylindrical outer frame to which the elastic body is entirely fixed. For example, as shown in the partial sectional view of FIG. 1, 1 is a cylindrical outer frame, 2 is an Oriswiss plate,
3 is an annular frame plate, and 4 is a cap that completely closes the upper end opening of the cylindrical outer frame 1. The annular frame plate 3 is placed together with the cap 4 on the step l& formed on the cylindrical outer frame 1, and the upper end of the cylindrical outer frame 1 is attached to the cap 4 as shown by the two-dot chain line in the figure. The annular frame plate 3 is fixed to the cylindrical outer frame 1 by bending and caulking the upper peripheral edge of the annular frame plate 3 .

要がある。However, in the conventional fluid-filled vibration isolator, the seal member 5 is provided separately from each component of the vibration isolator described above, so the seal member 5 seals the space. To seal the interior of S, it is necessary to seal between the seal member 5 and the outer periphery of the annular frame plate 3, and between the seal member 5 and both sides of the recess, that is, between the stepped portion 11 and the cap 4.
従って、このよりにシール部分が増加することＫよって
