PROBLEM TO BE SOLVED: To increase the durability, and to improve the vibration attenuating performance by providing a projecting surface part projected inward in each inner surface of a rubber elastic wall part opposite to a main liquid chamber and extended in the radial direction in a loading direction from nearly both ends of an inner cylinder. SOLUTION: In a liquid sealed mount, a projecting surface 42 projected inward is provided in each inner surface of a rubber elastic wall part (wall part) 22 opposite to a main liquid chamber 16 and extended in the radial direction in a loading direction from nearly both ends of the inner cylinder 10. With this structure, in case of compressing the wall part 22, generation of local outward swelling of the wall part is prevented. In a case where an inner cylinder 10 and an outer cylinder 12 are fitted to an oscillating member and a fixed member, the rubber elastic body is elastically deformed by the applied load so as to take a balance of displacement between the inner and the outer cylinders 10, 12, and in a case where the vibration is input, the rubber elastic body is elastically deformed so as to generate the displacement difference between the inner and the outer cylinders 10, 12. Volume of the main and an auxiliary liquid chambers 16, 18 are enlarged or reduced, and the liquid sealed in the main and the auxiliary liquid chambers 16, 18 is flowed through an orifice passage 20, and attenuates the vibration with the flowing resistance thereof. |
