PURPOSE: A hydraulically sealed engine mount utilizing a behavior of rubber is provided in which the engine mount has an enhanced structure so that the hydraulic pressure moves in one direction by a compression and expansion of a rubber member upon the vibration of the engine. CONSTITUTION: A hydraulically sealed engine mount absorbing a vibration of the engine by being compressed and expanded by the vibration of the engine, the engine mount comprising a rubber member(120) arranged at multiple places of an automobile body(100) so as to support the engine(105), two fluid chambers(130, 130a) to be filled with an incompressible fluid, the two chambers(130, 130a) being arranged inside of the rubber member(120), deformation preventive members(140, 140a) attached to portions of inner surfaces of the fluid chambers(130, 130a), the deformation preventive members(140, 140a) being made up of a material harder than the rubber member(120), and a pipe(150) connecting the chambers(130, 130a) so that the fluid in those chambers flows in accordance with the compression and expansion of the rubber member(120).
