A refrigerator (1, 100) comprising: a cabinet (10, 110) comprising a refrigerating compartment (12, 112) and a freezing compartment (13, 113); a refrigerating compartment door (20, 120) configured to open and close at least a portion of the refrigerating compartment (12, 112); a dispenser disposed at the refrigerating compartment door (20, 120) and configured to dispense ice pieces; an ice bank disposed at a back surface of the refrigerating compartment door (20, 120) to supply the ice pieces to the dispenser; an ice maker disposed in the freezing compartment (13, 113) and configured to make the ice pieces; and an ice transfer device disposed in the freezing compartment (13, 113) and configured to transfer the ice pieces made by the ice maker to the ice bank, wherein the ice transfer device comprises: a piston configured to push the ice pieces made by the ice maker; an ice chute configured to guide the ice pieces pushed by the piston to the ice bank; a storage member configured to store the ice pieces made by the ice maker; and a housing configured to receive an ice piece transported from the storage member, wherein the piston is positioned at least partially in the housing and reciprocates to push the ice piece received in the housing, characterized in that: the refrigerator (1, 100) further comprises a shutter positioned within the housing and is configured to selectively open and cover a front opening of the housing, the front opening of the housing being an opening through which ice pieces exit the housing when pushed toward the ice chute by the piston, wherein the shutter is rotated to open the front opening of the housing based on reciprocation of the piston, wherein the shutter is contacted to the piston or is spaced from the piston based on reciprocation of the piston, wherein a protrusion rib protruding upward and a receiving groove recessed from each of both sides of the protrusion rib are provided at a center of a front end of the piston, and wherein the protrusion rib and the receiving groove are lengthily disposed in front and rear directions so as to guide the rotation of the shutter when the piston is moved. a cabinet (10, 110) comprising a refrigerating compartment (12, 112) and a freezing compartment (13, 113);
