PURPOSE: To heighten the characteristic of a vibration-proof mount to the change with the lapse of time or the like and reliability to liquid leak or the like by fitting two fittings through seal rubber to form the outline of a main liquid chamber and an upper diaphragm sub-liquid chamber.
CONSTITUTION: A vibration-proof base body 3 is vulcanization-bonded to a cylindrical body fitting 20 provided at the periphery of a fitting recessed part 19, and the diaphragm 10 of a first diaphragm sub-liquid chamber 7 is vulcanization-bonded to an intermediate cylindrical fitting 21 to which the body fitting 20 is fitted. The body fitting 20 and the intermediate cylindrical fitting 21 are fitted in the liquid-tight state through seal rubber 22, and a partition plate 23 with an orifice 5 is interposed to form a main liquid chamber 4 and the first diaphragm sub-liquid chamber 7. This results in heightening the characteristic of a vibration-proof mount to the change with the lapse of time or the like and reliability to liquid leak or the like.
