PURPOSE: A hydraulic mounting insulator is provided to effectively insulate vibration of a wide area with inexpensive mechanical structure. CONSTITUTION: A hydraulic mounting insulator(40) forms a fluid chamber between a main rubber(42) and a diaphragm(44). The fluid chamber is divided into a low-viscosity fluid chamber(48) having fluid of low viscosity and a high-viscosity fluid chamber(50) having fluid of high viscosity by an intermediate diaphragm(46). A first fluid-damping unit(60), operating in intermediate frequency-intermediate displacement, is installed to the inside of the low-viscosity fluid chamber. A second fluid-damping unit(70), operating in low frequency-large displacement, is installed to the high-viscosity fluid chamber.
