PURPOSE: A damper driving device is provided to effectively reduce noise generated by driving a damper which controls the inflow of cold air to a storage chamber of storage such as a refrigerator. CONSTITUTION: A damper driving device drives a damper which controls the inflow of cold air to a storage chamber by being installed in the middle of a duct supplying cold air to the storage chamber. The damper driving device comprises a casing (310) with the opened top surface, a pair of vertical supports (350), a driving motor (330), and sound isolation sheets (370). The vertical supports are formed perpendicularly on the bottom surface of the casing by being spaced from each other. The driving motor, which is arranged in a fixing bracket (334), rotates normally and reversely and drives the damper. The sound isolation sheets are attached onto the top surfaces of the vertical supports.
