PURPOSE: A hydraulic bush is provided to generate damping force in the axial direction of a strut mount by including an upper axle, a lower axle, and an insulator with a flow path connecting each axle. CONSTITUTION: A hydraulic bush comprises upper and lower axles(131,133), upper and lower flow paths(135), a connection flow path(139), and a stopper(140). The upper and lower axles are concavely formed on the top and bottom of an insulator(130), respectively. The upper and lower axles are filled with the working fluid. The upper and lower flow paths are formed on the top and the bottom of the outer surface of the isolator along the columnar direction thereof. The upper and lower flow paths are connected to the upper and lower axles. The connection path is formed at the center of the outer surface of the insulator. The stopper is mounted on the upper and lower parts of the insulator, respectively.
