A refrigerator includes a main body, a receiving portion defined within the main body, a shelf disposed within the receiving portion having at least one auxiliary hinge portion disposed at a rear thereof, a storage tray slidably extractable from within the receiving portion and adjacent the shelf when the storage tray is received within the receiving portion, and a front cover disposed on a front surface of the storage tray to be rotated upward and opened when the storage tray is extracted from within the receiving portion and having at least one holder portion disposed on a rear surface thereof to be coupled to the at least one auxiliary hinge portion. By the configuration, the front cover is structurally reinforced, and it is possible to prevent the front cover from drooping and prevent a gap between the front cover and the upper shelf.
