Abstract
A damping liquid for a hydraulic vibration-damping mount is composed of glycol, water and 2 to 20 weight % of age resistor having ozone resistance. The damping liquid gradually diffuses and infiltrates into a rubber member defining a liquid chamber of the hydraulic vibration-damping mount thereby remarkably improving the ozone resistance thereof.
