In addition, a pressure receiving chamber, into which vibrations to be damped are input, each of which is filled with a predetermined incompressible fluid, and at least a portion thereof is defined by a flexible membrane. A variable volume equilibrium chamber is formed by sandwiching a partition member that extends in a direction substantially perpendicular to the vibration input direction and communicates with each other through an orifice passage. A fluid-filled vibration damping mount is provided with a movable member that can be displaced a predetermined distance in a direction to absorb the fluid pressure difference between the two chambers when the fluid pressure of the balance chamber is applied thereto. The movable member is made of an elastomer having a lower rigidity than the annular divided body, and the movable member is made of an elastomer having a lower rigidity than the annular divided body, and the movable member is made of an elastomer having a lower rigidity than the annular divided body. of,
By sandwiching between the annular divided bodies, the central hole of the annular divided bodies is closed, and at the inner peripheral edge of the annular divided bodies,
A fluid-filled vibration isolating mount characterized in that a displacement regulating portion is provided on both side surfaces of the movable member, the displacement regulating portion having abutting surfaces facing each other at a predetermined distance.
