What is claimed is: 1. A refrigerator comprising: a body having a cooling chamber; a door arranged at a front side of the cooling chamber; a lifting frame movably connected to the door to move up and down, the lifting frame having an overall width dimension measured from one side of the lifting frame to the other side of the lifting frame in a first direction; a basket having a bottom and a plurality of side walls extending upward from the bottom, the bottom of the basket being supported by the lifting frame, the bottom of the basket having a greater width in the first direction than the overall width of the lifting frame in the first direction; and a coupling structure connecting the lifting frame to the bottom of the baskets, the coupling structure including: a reinforcing rib protruded from an edge of the lifting frame for reinforcing the lifting frame, and a groove in a bottom surface of the basket to insert the reinforcing rib formed at the lifting frame therein. 2. The refrigerator of claim 1, further comprising a driving unit for lifting the lifting frame. 3. The refrigerator of claim 2, wherein the driving unit comprises: a driving arm roll-motioned at the lifting frame and hinge-connected to the door, for lifting the lifting frame; and a driving motor for generating a driving force for rotating the driving arm. 4. The refrigerator of claim 2, further comprising a control unit for controlling the driving unit and thereby lifting the basket. 5. The refrigerator of claim 4, wherein the control unit comprises: a switch adjusted by a user; a first sensor mounted at an upper end of the door for sensing a position that the lifting basket is lifted to the maximum; a second sensor mounted at a lower end of the door for sensing a position that the lifting basket is descended to the maximum; and a controller for turning on/off a power applied to the driving motor according to a signal applied from the switch, the first sensor, and the second sensor. 6. The refrigerator of claim 1, wherein the door is provided with a lifting rail for guiding the lifting frame to be lifted. 7. The refrigerator of claim 1, wherein the lifting frame comprises: a lifting unit connected to the door to be lifted in a perpendicular direction; and a mounting unit horizontally extended from an end of the lifting unit and on which the basket is positioned. 8. The refrigerator of claim 1, wherein the reinforcing rib comprises: a first rib formed at an edge of the lifting unit; and a second rib formed at edges of both lateral surfaces of the mounting unit. 9. The refrigerator of claim 1, wherein the reinforcing rib further comprises a third rib formed at an edge of a front surface of the mounting unit. 10. The refrigerator of claim 8, wherein the groove includes a first groove in a rear surface of the basket for inserting the first rib formed at the lifting frame therein. 11. The refrigerator of claim 8, wherein the groove includes a second groove in the bottom of the basket for inserting the second rib therein and preventing the basket from being moved in right and left directions at the bottom of the basket. 12. The refrigerator of claim 9, wherein the groove includes a third groove in the bottom of the basket for inserting the third rib of the lifting frame therein and preventing the basket from being moved in back and forth directions at the bottom of the basket. 13. The refrigerator of claim 3, wherein the lifting frame is provided with a stopper protruded from a lower surface thereof for preventing the driving arm from being detached from the lower surface of the lifting frame. 14. The refrigerator of claim 1, wherein the coupling structure includes: a plurality of grooves in the bottom surface of the basket; and a plurality of ribs on the lifting frame, each of the plurality of ribs being receivable in a corresponding groove of the plurality of grooves. 15. A refrigerator comprising: a body having a cooling chamber; a door arranged at a front side of the cooling chamber; a lifting frame movably connected to the door to move up and down, the lifting frame having an overall width dimension measured from one side of the lifting frame to the other side of the lifting frame in a first direction, the lifting frame including: a first frame connected to a rear surface of the door to be lifted in a perpendicular direction; a second frame extended from an end of the first frame at an inclination with respect to the first frame; and a third frame horizontally extended from an end of the second frame and on which the basket is positioned, the second frame being oriented in a plane different from that of the third frame; a basket having a bottom and a plurality of side walls extending upward from the bottom, the bottom of the basket being supported by the lifting frame, the bottom of the basket having a greater width in the first direction than the overall width of the lifting frame in the first direction; and a coupling structure connecting the lifting frame to the bottom of the basket such that a portion of one of the basket and the lifting frame is received in the other of the basket and the lifting frame. 16. The refrigerator of claim 15, wherein the second frame is provided with an opening for preventing an interference with components of the driving unit. 17. The refrigerator of claim 15, wherein the coupling structure includes a reinforcing rib protruded from an edge of the lifting frame for reinforcing the lifting frame. 18. The refrigerator of claim 17, wherein the reinforcing rib comprises: a first rib formed at an edge of the first frame; a second rib formed at an edge of the second frame; and a third rib formed at edges of both lateral surfaces of the third frame. 19. The refrigerator of claim 18, wherein the reinforcing rib further comprises a fourth rib formed at an edge of a front surface of the third frame. 20. The refrigerator of claim 15, wherein the basket is provided with an interference preventing unit concaved towards an inner side of the basket for preventing an interference with components of the driving unit when the basket is lowered. 21. The refrigerator of claim 20, wherein the basket is provided with reinforcing ribs formed to cross one another with a certain interval at a lower surface thereof for reinforcing the basket. 22. The refrigerator of claim 18, wherein the coupling structure includes a first groove at a rear surface of the basket for inserting the first rib formed at the lifting frame therein. 23.
