Claim:
1. A liquid sealed mount comprising: an elastic main body member which is formed as a vibration isolating main body and has a downwardly open liquid chamber concave section, a diaphragm for covering the liquid chamber concave section, a liquid chamber formed between the liquid chamber concave section and the diaphragm, a partition member for partitioning the liquid chamber into a primary liquid chamber and a secondary liquid chamber, an orifice passage provided in the partition member so as to provide communication between the primary liquid chamber and the secondary liquid chamber, and an outer cylinder in which the elastic main body member, the partition member and the diaphragm are accommodated so as to be combined together, wherein an upper part of the outer cylinder functions as a stopper, and the outer cylinder has an upper end portion opening upwardly around the elastic main body member and a lower end portion opening downwardly, and wherein a water drain passage which provides communication between the upper end opening and the lower end opening of the outer cylinder is formed between an outer circumferential portion of a liquid chamber formation unit which is accommodated inside in a lower part of the outer cylinder so as to form the liquid chamber and an inner circumferential surface of the lower part of the outer cylinder, further comprising an elastic main body member drain recess and a partition member drain recess which are provided in each of outer circumferential portions of the elastic main body member and the partition member, a fixing ring being configured to support the diaphragm in contact therewith and to be inserted into an inside of the lower part of the outer cylinder, and a fixing ring drain recess being provided in an outer circumferential portion of the fixing ring, wherein the water drain passage is formed by providing communication between the elastic main body member drain recess, the partition member drain recess and the fixing ring drain recess on the inside of the outer cylinder in the direction of a mount axis.
