Claims

[Claims for Utility Model Registration] An inner cylinder member; an outer cylinder member having a window portion disposed concentrically or eccentrically on the outside of the inner cylinder member; and a window portion of the outer cylinder member so as to cover the window portion. , a seal sleeve fitted onto the outer peripheral surface of the outer cylindrical member, and two seal sleeves located between the inner cylindrical member and the outer cylindrical member and extending axially through both sides of the inner cylindrical member. a rubber elastic body having two connecting portions each extending in the radial direction with a central angle forming a substantially V-shaped cross section, which connects the two members in a state in which two cavities are formed; a pair of pressure receiving chambers each formed by covering, with the seal sleeve, a pocket portion formed in each connecting portion and opening outward through the window portion of the outer cylinder member; The space is located in one of the spaces formed between the inner cylinder member and the outer cylinder member, and is defined at least in part by a flexible thin film, and an equilibrium chamber formed by covering a variable-volume recess that opens toward the other side with the seal sleeve; orifice means for communicating the equilibrium chamber with the pair of pressure receiving chambers, respectively; and the pressure receiving chamber. A fluid-filled vibration-isolating bushing comprising: an incompressible fluid sealed so as to fill a chamber and an equilibrium chamber, respectively.
