A refrigerator comprising: an ice maker configured to generate ice; an ice bucket configured to store ice; a transfer member configured to transfer ice stored in the ice bucket; a drive motor configured to generate a driving force for driving the transfer member; a first coupler connected to the transfer member, and including an insertion portion and a first inclined portion; and a second coupler connected to the drive motor, and including a seating portion to receive the insertion portion of the first coupler, and a second inclined portion to guide, along with the first inclined portion, the insertion portion of the first coupler to the seating portion, wherein the first inclined portion tapers from an outer circumferential surface of the insertion portion so that an outer circumference of the first inclined portion decreases in a direction in which the first coupler is inserted into the second coupler, the second inclined portion expands from an inner circumferential surface of the seating portion so that an inner circumference of the second inclined portion increases in a direction opposite to the direction in which the first coupler is inserted into the second coupler, and when the first coupler is inserted into the second coupler and an axis of rotation of the first coupler is not aligned with an axis of rotation of the second coupler, the second inclined portion is arranged to guide the first inclined portion toward the seating portion while aligning the axis of rotation of the first coupler with the axis of rotation of the second coupler, wherein the first coupler further comprises a first engaging portion provided on an outer circumferential surface of the insertion portion and an outer circumferential surface of the first inclined portion, and the second coupler further comprises a second engaging portion provided on an inner circumferential surface of the seating portion and an inner circumferential surface of the second inclined portion, wherein the first engaging portion comprises a plurality of first peak portions protruding in an outward radial direction from and surrounding an outer circumferential surface of the first coupler and a plurality of first valley portions that are recessed from the first peak portions, and the second engaging portion comprises a plurality of second peak portions protruding in an inward radial direction from and surrounding an inner circumferential surface of the second coupler and a plurality of second valley portions that are recessed from the second peak portions, wherein when the first coupler is inserted into the second coupler, the first peak portions and the second peak portions are configured to interact so that the first coupler is rotated such that each of the first peak portions aligns with respective ones of the second valley portions. an ice maker configured to generate ice;
