PURPOSE: A foldable damper for a refrigerator is provided to prevent the leakage of cold air by increasing adhesion between a cold air port and a sheet attached to a plate. CONSTITUTION: A foldable damper for a refrigerator comprises a frame(10), a cold air port, a plate, and a drive part(40). The cold air port is formed at the center of the frame. The plate is rotated by a pivot axis(20) and opens and closes the cold air port. The plate is partitioned into a first plate(31) and a second plate(32). One end of the first plate is coupled with the pivot axis and the other end of the first plate is hinge-coupled with one end of the second plate. The drive part comprises a stepping motor. The stepping motor rotates the pivot axis.
