Abstract: Disclosed is the auger in an ice bin mounted in a refrigerator, and the like. The auger in the ice bin is configured to rotate an auger having spiral-shaped transfer blades and to dispose ice in each space between the transfer blades of the auger for transfer. Accordingly, a certain amount of ice can always be discharged without simultaneously discharging a great amount of ice, and a user may select the number of ice, thus to diversity functions of an ice dispenser. In addition, since the auger is made of a flexible material, the ice can be prevented from being crushed during transfer, thereby enhancing the reliability of the ice dispenser.
