| description | A liquid-filled vibration isolator includes an inner cylindrical metal member; a cylindrical intermediate metal member disposed outside the inner cylindrical metal member in a substantially coaxial manner and including a pair of ring portions disposed at corresponding axial ends thereof, a pair of connection portions integrally connecting the ring portions, and a pair of window portions defined by the ring portions and the connection portions; a rubber elastic-body connecting the intermediate metal member and the inner cylindrical metal member and having cavity portions corresponding to the window portions; and an outer cylindrical metal member fixedly disposed outside the intermediate metal member and sealed in a liquid-tight manner against the intermediate metal member by means of a rubber seal portion. The rubber elastic-body includes first and second diaphragm portions formed on the front side of the inner cylindrical metal member with respect to the front-rear direction of the vehicle, and third and fourth diaphragm portions formed on the rear side of the inner cylindrical metal member with respect to the front-rear direction of the vehicle. Among the first through fourth diaphragm portions, the first and fourth diaphragm portions located diagonally opposite each other with respect to the inner cylindrical metal member are longer than the second and third diaphragm portions. |
