Abstract
A liquid-sealed body mount comprising an inner and an outer cylinders concentrically disposed, a first and a second rubber members provided mutually in axially spaced relation and connecting both cylinders therebetween, an intermediate rubber plate means partitioning axially an enclosure surrounded by both cylinders and both rubber members into a first and a second liquid chambers, an orifice for communication with both chambers apertured in the intermediate means, and a liquid filled in both chambers. The intermediate rubber plate means is configured, when assembled, so as to be preliminarily deformed in the shearing direction, assuming a shade-like form and, when imposed with a prescribed load, so as to retain a neutral state of intersecting orthogonally both cylinders, whereby equalized vibration-preventing characteristics against oscillations on both bound and rebound sides are achieved.
