PURPOSE: A fluid filled type engine mount is provided to effectively isolate the vibration of high frequency band. CONSTITUTION: A curved partition(9) having many recessed portions(9a) is installed between a main rubber(1) and a lower rubber(7) to divide an upper liquid chamber(6) and a lower liquid chamber(8). A through hole is formed in each recessed portion of the curved partition. Many protruded pillars(1a) are formed under the main rubber to be corresponding to the recessed portions of the curved 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.
