In a keeping device for a refrigerator, a moving shelf is installed to adjust the space between door baskets according to the height of food items received in the door baskets. When the moving shelf is folded, a long food item can be stably received, and when the folded moving shelf is unfolded, the receiving space can be extended to receive more food items. Also, because moving support portions supporting the moving shelf are provided at both sides, collision noise can be reduced when the moving shelf is unfolded, and because a restraining unit is provided between the moving shelf and the door, the folded state of the moving shelf can be stably maintained. In addition, because the keeping device is hung and fixed such that it is tightly attached to the door, the keeping space can be extended.

1. A refrigerator comprising: a door for opening and closing a freezing chamber or a refrigerating chamber;a door basket supported by an inner side surface of the door;a moving shelf that is positioned at an upper side of the door basket, that is supported by the inner side surface of the door, and that is rotatable relative to the inner side surface of the door;a support unit configured to maintain the moving shelf in a first state that allows the moving shelf to receive a food item; anda restraining unit configured to maintain the moving shelf in a second state in which the moving shelf does not support the food item,wherein the support unit comprises a fixed support portion that protrudes from a side wall portion that extends away from the inner side surface of the door and that has a length shorter than a length of the moving shelf, and a moving support portion positioned on a lower surface of the moving shelf and configured to be supported by the fixed support portion, andwherein an upper surface of the fixed support portion that supports the moving support portion has a horizontal flat surface, and the moving support portion has a curved surface that enables the moving support portion to roll against the horizontal flat surface of the fixed support portion during rotation of the moving shelf between the first and second states. 2. The refrigerator of claim 1, wherein the moving support portion further comprises a straight surface extended from the curved surface, and wherein the straight surface of the moving support portion is sloped with respect to the horizontal flat surface of the fixed support portion. 3. The refrigerator of claim 1, wherein the door comprises one or more reinforcing support portions to support the moving shelf. 4. The refrigerator of claim 1, wherein the restraining unit comprises: at least one first protrusion fixed to the door; anda second protrusion formed on at least one of both side surfaces of the moving shelf so as to allow the first protrusion to be supported thereon. 5. The refrigerator of claim 4, wherein the second protrusion is formed at the moving support portions, respectively. 6. The refrigerator of claim 4, wherein at least one of the first and second protrusions has a rectangular shape. 7. The refrigerator of claim 6, wherein the first protrusion is positioned at a rotation locus of the second protrusion. 8. The refrigerator of claim 6, wherein a hinge protrusion and a hinge recess are formed between the door and the moving shelf in order to allow the moving shelf to rotate, and the hinge recess is formed as a long recess-like shape to allow the moving shelf to move in a rotational radius direction. 9. The refrigerator of claim 1, wherein a rotational center and the center of gravity of the moving shelf have a certain interval on a plane so that the restraining unit is restraining by the difference between the rotational center and the center of gravity. 10. A keeping device for a refrigerator, the keeping device comprising: a frame detachably coupled to a door for opening and closing a freezing chamber or a refrigerating chamber;a door basket coupled to the frame;a moving shelf positioned at an upper side of the door basket and rotatably coupled to the frame;a support unit configured to maintain the moving shelf in a first state in which the moving shelf receives a food item; anda restraining unit configured to maintain the moving shelf in a state in which the moving shelf does not support a food item,wherein the support unit includes a fixed support portion that protrudes from a side wall portion of the frame and that has a length shorter than a length of the moving shelf, and a moving support portion positioned on a lower surface of the moving shelf and configured to be supported by the fixed support portion, andwherein an upper surface of the fixed support portion that supports the moving support portion has a horizontal flat surface, and the moving support portion has a curved surface that enables the moving support portion to roll against the horizontal flat surface of the fixed support portion during rotation of the moving shelf between the first and second states. 11. The keeping device of claim 10, wherein the moving support portion further comprises a straight surface extended from the curved surface, and wherein the straight surface of the moving support portion is sloped with respect to the horizontal flat surface of the fixed support portion. 12. The keeping device of claim 10, wherein the frame comprises one or more reinforcing support portions to support the moving shelf. 13. The keeping device of claim 10, wherein the restraining unit comprises: at least one first protrusion fixed to the frame; anda second protrusion formed on at least one of both side surfaces of the moving shelf so as to allow the first protrusion to be supported thereon. 14. The keeping device of claim 13, wherein the second protrusion is formed at the moving support portions, respectively. 15. The keeping device of claim 13, wherein the first protrusion is positioned at a rotation locus of the second protrusion. 16. The keeping device of claim 13, wherein a hinge protrusion and a hinge recess are formed between the door and the moving shelf in order to allow the moving shelf to rotate, and the hinge recess is formed as a long recess-like shape to allow the moving shelf to move in a rotational radius direction.
