Abstract: Disclosed herein are an ice maker assembly movably disposed in a storage space, and a refrigerator comprising the same are provided. An ice maker assembly disposed in a storage space of a refrigerator to form ice, the ice maker assembly includes an ice maker unit configured to form ice and a basket unit configured to store the ice formed in the ice maker unit, wherein the ice maker unit includes a frame mounted at the refrigerator, a tray mounted at the frame and having a space in which the ice is formed, a water tank tiltably mounted at the frame and configured to supply water to the tray, and water stored in the water tank is supplied to the tray when the water tank is tilted in one direction.

Abstract: Disclosed herein is a refrigerator having a locker provided with a magnetic member to fix an ice bucket by use of magnetic attractive force and coupled to an upper wall of a body of the refrigerator. The ice bucket is removed by raising and then pulling it, while the locker is provided with an elastic guider to guide the removal of the ice bucket. The elastic guider is forced upward by the ice bucket during its removal and returns to its original position when the ice bucket is not forcing it upward.
