An ice bank for a refrigerator, comprises: an ice bank body having an ice-crushing unit and a discharging passage; and a mode conversion apparatus disposed in the ice bank body for guiding ice cubes to the ice-crushing unit, or guiding the ice cubes to the discharging passage for discharge in a non-crushed state, wherein the mode conversion apparatus comprises: a guide member rotatably disposed in the ice bank body for guiding ice cubes to the ice-crushing unit, or to the discharging passage for discharge in a non-crushed state; an elastic member for elastically supporting the guide member; and a driving unit for generating a driving force so as to rotate the guide member. Accordingly, ice cubes can be dispensed in a non-crushed state or in a crushed state, and limitations in installation places of the ice bank can be reduced.
