A refrigerator which provides an improved installation structure of a receiving device disposed in a storage chamber such that the receiving device can be stably supported in the storage chamber and easily mounted on and separated from the storage chamber. The refrigerator includes a shelf fixing structure which fixes a shelf to the storage chamber. The shelf fixing structure includes an engaging protrusion formed on a lower surface of the shelf at one side of the shelf, a stepped surface formed at the other side of the shelf, a restriction groove formed at a position corresponding to the engaging protrusion to restrict the engaging protrusion, and a restriction portion formed at a position corresponding to the stepped surface to restrict the stepped surface.

What is claimed is: 1. A refrigerator comprising: a storage chamber; a support member fixed to each side wall of the storage chamber; a shelf coupled to the support member while covering a receiving container arranged beneath the shelf; and a self fixing structure to separably fix the shelf to the support member, wherein the support member includes a support surface to support the shelf, and a rail part formed beneath the support surface while being integral with the support surface, to support the receiving container such that the receiving container is slidable in a forward-backward direction, wherein the self fixing structure includes a stepped surface formed at a rear edge portion of the shelf such that the stepped surface is downwardly stepped from an upper surface of the shelf, a restriction portion formed at the support member such that the restriction portion is engaged with the stepped surface, an engaging protrusion formed at a front portion of one of the shelf and the support member, and a restriction groove formed at the other one of the shelf and the support member such that the engaging protrusion is fitted into the restriction groove, and wherein the restriction portion includes an extended portion extended upward from the support surface of the support member, and a bent portion bent from the extended portion to cover the stepped surface of the shelf. 2. The refrigerator according to claim 1, wherein the stepped surface is laterally inwardly stepped from a side surface of the shelf to form a step having the same height as the extended portion. 3. The refrigerator according to claim 1, wherein the bent portion is flush with the upper surface of the shelf in a state in which the shelf is supported by the support member. 4. The refrigerator according to claim 1, wherein the engaging protrusion is downwardly extended from the side surface of the shelf. 5. The refrigerator according to claim 1, wherein the restriction portion is formed integrally with the support member. 6. The refrigerator according to claim 1, wherein the restriction groove is provided with a restriction rib extended across the restriction groove, and the engaging protrusion is provided with an engaging groove, in which the restriction rib is engaged. 7. The refrigerator according to claim 3, wherein the bent portion has a lower surface having the same shape as the stepped surface, and an upper surface having the same shape as the upper surface of the shelf. 8. The refrigerator according to claim 7, wherein the stepped surface is formed at the upper surface of the shelf, and the engaging protrusion is formed at a lower surface of the shelf. 9. A refrigerator comprising a storage chamber, a shelf installed in the storage chamber, a support member fixed to each side wall of the storage chamber, to support the shelf, and a self fixing structure to fix the shelf to the support member, wherein: the self fixing structure includes an engaging protrusion formed at a front portion of one of the shelf and the support member, and a restriction groove formed at the other one of the shelf and the support member at a position corresponding to the engaging protrusion, to restrict the engaging protrusion, a stepped surface formed at an upper surface of a rear portion of the shelf, and a restriction portion formed on the support member at a position corresponding to the stepped surface, to restrict the stepped surface; and the restriction portion is seated on the stepped surface such that the restriction portion is not protruded from the upper surface of the shelf in a state in which the restriction portion is engaged with the stepped surface of the shelf. 10. The refrigerator according to claim 9, wherein the support member includes a support surface extended in a forward-backward direction along the side wall of the storage chamber, and a rail part formed beneath the support surface while being integral with the support surface such that the rail part is extended in the forward-backward direction, to support the receiving container. 11. The refrigerator according to claim 9, wherein the restriction portion includes an extended portion extended upward from the support surface, and a bent portion bent from the extended portion toward a center of the shelf. 12. The refrigerator according to claim 9, where the stepped surface of the shelf includes a first stepped surface laterally inwardly stepped from the side wall of the shelf, and a second stepped surface downwardly stepped from the upper surface of the shelf.
