Claims

[Scope of utility model registration request]

An elastic body 4 such as rubber is interposed between the outer case 1 and the inner sleeve 3 located on the inner circumferential side thereof, and two liquid chambers 5 are partitioned by the elastic body 4 and filled with hydraulic fluid. 6, and the liquid chambers 5 and 6 communicate with each other via an orifice 7. 4 and liquid chambers 5 and 6
It consists of two through holes 11 and 12 that communicate the annular hole 10 with the liquid chambers 5 and 6 at a position adjacent to one partition wall 4a, which is formed by partitioning the annular hole 1.
A liquid-filled bushing characterized in that a sealing body 14 that prevents short-circuiting of the working fluid between the two through holes 11 and 12 is fitted into the inside of the bushing 1 so as to be movable within a minute range.
