PURPOSE: A fluid filled type engine mount is provided to isolate the vibration of high frequency band effectively. CONSTITUTION: An upper partition(10) and a lower partition(9) are installed between a main rubber(1) and a lower rubber(7). An operating fan(11) to be rotated centering around a shaft is installed between the upper partition and the lower partition. Thereby, the vibration of a high frequency band within 150¯250Hz is isolated effectively. Therefore, the efficiency of an engine mount is improved. Moreover, the cost is saved and the defect is prevented by simplifying the partition structure with a single partition.
