A refrigerator includes an auger including a transfer unit transferring ice in an ice bucket and a driving gear unit formed at the end of the transfer unit and transmitting rotary force and an agitator including an agitation unit agitating the ice in the ice bucket and a driven gear unit combined with the end of the agitation unit. The auger is formed integrally and thus, the number of parts of the auger is reduced and the assembled structure of the auger is simplified. The ice bucket is fixed in the upward, downward, and horizontal directions by a dual fixing device and is easily attached to and detached from a door of the refrigerator.
