PURPOSE:To provide a mixture preventing liquid with the higher viscosity and lower specific gravity than working liquid between the working liquid and a working gas so as to facilitate manufacture in a liquid-sealed type vibration-proof mount in which liquid pressure of the working liquid in a casing is changed by vibration of a vibrating body through an elastic member so that the working liquid flows through an orifice. CONSTITUTION:A casing 6 is constituted by caulking and fixing an upper case member 5 and an orifice supporting plate 9 to a lower case member 4, a predetermined amount of working liquid and air is sealed in this casing 6, and a mixture preventing liquid such as engine oil whose viscosity is higher and specific gravity is lower than the working liquid of ethylene glycol 5 and whose affinity is small is provided between the working liquid and the air. That is, the working liquid with the highest specific gravity is reserved on the lowest side in an engine 6 to the liquid level soaking an orifice 11, and a layer 21 of the mixture preventing liquid with the predetermined thickness is formed on top of the working liquid. Accordingly, the air can be separated from the working liquid not by a conventional diaphragm, and manufacture is facilitated. |
