A drawer of a refrigerator includes a basket extractable and retractable through the refrigerator while having a storage space surrounded by four wall surfaces. A first partition is slidably mounted to facing first and third ones of the wall surfaces, to move between facing second and fourth ones of the wall surfaces, a second partition is arranged to cross the first partition and is slidably mounted to the second and fourth wall surfaces, to move between the first and third wall surfaces. A moving guide disposed at an intersection between the first and second partitions, to guide movements of the first and second partitions. The drawer achieves an enhancement in utilization by virtue of the partitions capable of varying a partitioned size of the drawer.
