ABSTRACT:
A refrigerator having an ice bank includes a rotation shaft to which a transfer unit for transferring ice pieces in the ice bank is connected, and having a coupling groove on an outer circumferential surface of the end thereof; a joint penetrated by the rotation shaft; a driving shaft connected to the joint, and transmitting a driving force of a motor to the joint; and a coupling ring coupled to the coupling groove of the rotation shaft penetrating the joint. Since the coupling ring is locked by the joint, the rotation shaft is prevented from being arbitrarily separated from the joint. The rotation shaft can be rotated in forward and backward directions. Furthermore, since the rotation shaft has a length shorter than a rotation shaft having screw threads and nuts, the motor can have a compact configuration.
