PURPOSE: A rolling device is provided to prevent the error of sensing by limiting the movement of steam to one direction, which can cause the malfunction of a unit for sensing the movement of a rolling member. CONSTITUTION: A rolling device comprises a roller unit(100), a cooling water injecting unit(200), a sensing unit(300), and an air current generator(400). The cooling water injecting unit is installed before a rolling member going out of the roller unit and injects cooling water to the rolling member. The sensing unit is installed before the cooling water injecting unit and senses the movement of the rolling member. The air current generator generates air current resisting to movement toward the sensing unit of steam by cooling water. The air current generator is arranged between the cooling water injecting unit and the sensing unit. The air current generator comprises an injecting nozzle to inject compressed air.
