PURPOSE:To rapidly switch from the high spring pressure to the low spring pressure, and vice versa by selectively shut off a passage between liquid chambers of a liquid-sealed elastic body in a torque rod bush. CONSTITUTION:A torque rod bush is provided with a liquid-sealed elastic body 3 where the liquid is sealed in two liquid chambers 4, 5 which are separated from each other, and the liquid chambers 4, 5 are communicated with each other through a passage 6 between the liquid chambers, an inner cylinder 1 and an outer cylinder 2 which are concentrically arranged, and fixes the liquid- sealed elastic body 3 therebetween, and an orifice shut-off means 8 which is fixed between this outer cylinder 2 and the liquid-sealed elastic body 3, and selectively shuts off the passage 6 between the liquid chambers of the liquid- sealed elastic body 3. |
