Abstract: The present invention relates to an ice maker for a refrigerator. The present invention provides an ice maker for a refrigerator, which is provided at one side of the refrigerator to make ice. The ice maker comprises an ice maker body provided with an ice-making tray for making ice; an ejector rotatably mounted at one side of the ice maker body so as to eject ice made in the ice-making tray to the outside; a water supply hopper provided at one side of the ice maker body and having at least an open portion so that the water supply hopper is supplied with water from a water supply source through a water supply tube and then transfers the water to the ice-making tray; and a hopper cover coupled to the water supply hopper so as to selectively open and close the open portion of the water supply hopper. According to the present invention, it is possible to avoid a phenomenon in which water supplied from an outer water supply source to the water supply hopper splashes to the outside.

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.
