PROBLEM TO BE SOLVED: To provide a liquid-sealed bush to perform effective damping of a load exerted in a main load input direction and a load in a direction crossing the aforesaid load. SOLUTION: Outer and inner cylinders 11 and 12 are interconnected through an elastic body 15 and main liquid chambers R1 and R2 are formed between the elastic body 15 and the outer 11 and auxiliary liquid chambers R3 and R4 peripherally connected thereto are formed and the main and auxiliary chambers are intercommunicated through orifices O1 -O3 . When a high load is inputted in a direction X-X', the volumes of the main liquid chambers R1 and R2 are reduced, extruded liquid passes through the orifices O1 -O3 and a damping force is generated through current resistance. When a load in a direction Z-Z is inputted under input of the load in a direction X-X', the volumes of the auxiliary liquid chambers R3 and R4 adjoining the main liquid chambers R1 and R2 are reduced, and through the passage of extruded liquid through the orifices O1 -O3 , a damping force is generated. |
