Claims

[Claims for Utility Model Registration] (1) An inner sleeve 1 and a first outer sleeve 2 are integrally molded via an elastic body 3, and an annular second sleeve is formed on the outer periphery of the first outer sleeve 2.
The outer sleeve 4 is attached to form two separate liquid chambers 5 and 6 between the elastic body 3 and orifices 7 and 8 between the first outer sleeve 2 and the second outer sleeve 4. The liquid chamber 5 and the liquid chamber 6 are formed to communicate with each other, and the orifices 7 and 8 are further provided with pressure adjustment mechanisms 9 and 10 for adjusting the liquid pressure in the liquid chambers 5 and 6. A liquid-filled bottle featuring: (2) The first inner sleeve 11 and one of the first outer sleeve half portions 14a are integrally molded via the elastic body 15, and the first inner sleeve 11
A second inner sleeve 12 is attached to the outer periphery of the sleeve via a bearing 16 so as to be movable in the axial direction, and
The second inner sleeve 12 and the other first outer sleeve half part 14a are integrally molded via an elastic body 15, and further, the one first outer sleeve half part 14a and the other first outer sleeve half part An annular member 18 having a U-shaped cross section is disposed in the center of the outer sleeve half 14a, the other outer sleeve half 14a, and an annular second outer sleeve 19 around the outer periphery of the annular member 18. is attached to form liquid chambers 20, 21 between the elastic body 15, and an orifice 22 is formed inside the annular member 18 to communicate the liquid chamber 20 and the liquid chamber 21, and the second
A liquid-filled bushing characterized in that the liquid pressure in liquid chambers 20 and 21 is adjusted by moving an inner sleeve 12 in the axial direction.
