A refrigerator comprising: a cabinet having a storage space; a door for opening and closing the storage space; a pair of support members (300, 400), each of which is provided at each of both sides of the storage space; a storage member provided between the pair of support members (300, 400) and inserted into and drawn out along the support members (300, 400), having an inlet on an upper surface so that food is inserted therethrough; a shielding member provided above the storage member, for shielding a rear portion of the inlet of the storage member; a cover member shielding a front portion of the inlet of the storage member, moving in an opposite direction of a moving direction of the storage member by interworking with insertion and draw-out operation of the storage member and moving backward between the shielding member and the storage member when the storage member is drawn out; and a driving unit connecting the storage member and the cover member so as to interwork with each other; wherein the driving unit includes: a first gear member coupled with the cover member and formed to be extended longitudinally forward and backward, moving in the same direction as that of the cover member; and a second gear assembly coupled with the storage member, moving in the same direction as that of the storage member when the storage member is inserted or drawn out; and a connection gear rotatably provided between the second gear assembly and the first gear member, connecting the second gear assembly with the first gear member, wherein the second gear assembly includes: a second gear member formed to be extended longitudinally forward and backward and connected with the connection gear by gear coupling; characterized by a binding member rotatably coupled to the second gear member and selectively coupled with a gear operation unit of the storage member by rotation, and wherein the binding member of the second gear assembly is released from coupling with the gear operation unit of the storage member when the cover member moves backward at maximum range. a cabinet having a storage space; a door for opening and closing the storage space; a pair of support members (300, 400), each of which is provided at each of both sides of the storage space; a storage member provided between the pair of support members (300, 400) and inserted into and drawn out along the support members (300, 400), having an inlet on an upper surface so that food is inserted therethrough; a shielding member provided above the storage member, for shielding a rear portion of the inlet of the storage member; a cover member shielding a front portion of the inlet of the storage member, moving in an opposite direction of a moving direction of the storage member by interworking with insertion and draw-out operation of the storage member and moving backward between the shielding member and the storage member when the storage member is drawn out; and a driving unit connecting the storage member and the cover member so as to interwork with each other; wherein the driving unit includes: a first gear member coupled with the cover member and formed to be extended longitudinally forward and backward, moving in the same direction as that of the cover member; and a second gear assembly coupled with the storage member, moving in the same direction as that of the storage member when the storage member is inserted or drawn out; and a first gear member coupled with the cover member and formed to be extended longitudinally forward and backward, moving in the same direction as that of the cover member; and a second gear assembly coupled with the storage member, moving in the same direction as that of the storage member when the storage member is inserted or drawn out; and a connection gear rotatably provided between the second gear assembly and the first gear member, connecting the second gear assembly with the first gear member, wherein the second gear assembly includes: a second gear member formed to be extended longitudinally forward and backward and connected with the connection gear by gear coupling; characterized by a binding member rotatably coupled to the second gear member and selectively coupled with a gear operation unit of the storage member by rotation, and wherein the binding member of the second gear assembly is released from coupling with the gear operation unit of the storage member when the cover member moves backward at maximum range. a second gear member formed to be extended longitudinally forward and backward and connected with the connection gear by gear coupling; characterized by a binding member rotatably coupled to the second gear member and selectively coupled with a gear operation unit of the storage member by rotation, and wherein the binding member of the second gear assembly is released from coupling with the gear operation unit of the storage member when the cover member moves backward at maximum range.
