A damper device for a refrigerator has a step motor used as the power source for rotating a baffle to open/close the cold air passage of the refrigerator in a more secured manner. The damper device for a refrigerator includes a frame installed in the cold air passage of the refrigerator and provided with an opening at the center thereof, a baffle rotatably installed on the frame to open/close the opening, a gear-equipped step motor installed on a surface of the frame and having a reduction gear and a motor integrally formed therein to transmit a rotation force necessary for opening/closing operation of the baffle, and a stopper adapted to mechanically limit the baffle in such a manner that it can be positioned in the desired opening position.
