PURPOSE: A device for preventing the creeping of an engine mount is provided to prevent the deformation, vibration, and noise of the engine mount due to the creeping of the engine mount. CONSTITUTION: A device(1) for preventing the creeping of an engine mount comprises an air tube(50), an air pump(110), a connection pipe(40), a check valve(130), an air filter(120), a pressure sensor(60), and an electronic control unit(100). The air tube is installed between a stopper plate(10) and a housing(20) of an engine mount. The air pump supplies air to the air tube or discharges air from the air tube to the outside. The connection pipe is installed between the air pump and the air tube. The check valve controls the opening and closing of the connection pipe. The air filter is mounted in the front end of the air pump. The pressure sensor measures air pressure inside the air tube. The electronic control unit controls the air pump and the check valve according the sensor signal of the air pressure, a key input signal, and an APS signal to supply or discharge air to or from the air tube.
