1. A rail assembly of a refrigerator, comprising: a rail housing mounted to a side surface of a food storage space and provided with a rail seating surface and a rail supporting end defining a lower part of the rail seating surface;a rail member received in the rail seating surface to guide a storage container to be drawn in and out, the rail member supported by the rail supporting end;a shaking prevention member coupled to a rear end of the storage container to prevent the storage container from shaking in a left and right direction;a rack member being spaced from a lower end of the rail housing, the rack member comprising an upper surface, a lower surface, and gear teeth extending upwardly from said upper surface, and said gear teeth inter-engaged with the shaking prevention member,wherein the shaking prevention member is movably contacted to the rack member, anda rack connector extending downwards from the lower end of the rail housing and being connected to the upper surface of rack member, at least one portion of the rack connector being disposed at an upper side of the gear teeth,wherein the shaking prevention member comprises: a rotatable pinion; anda shaft coupled to a central part of the pinion and being lower than the rail supporting end, and higher than the upper surface of the rack member. 2. The rail assembly as claimed in claim 1, wherein the rack connector is extended downwards at an angle from the lower end of the rail housing. 3. The rail assembly as claimed in claim 1, wherein the rail housing is formed with the rail seating surface depressed at a predetermined depth so that the rail member is firmly seated. 4. The rail assembly as claimed in claim 1, further comprising separation preventing pieces projected from an upper end and the lower end of the rail housing, respectively, to prevent the separation of the rail member. 5. The rail assembly as claimed in claim 4, wherein the separation preventing pieces are formed to be spaced from one another at a predetermined distance. 6. The rail assembly as claimed in claim 1, wherein the rail member is a structure that can be drawn out in a multi-stage. 7. The rail assembly as claimed in claim 1, wherein the rack connector extends downwardly and inwardly from the rail housing. 8. A refrigerator, comprising: a main body having a storage space for storing foods;a storage container provided to be able to be drawn in and out to the storage space;rail housings coupled to both sides of the storage space, the rail housing provided with a plurality of rail supporting ends;rail members coupled to both sides of the storage container and respectively received in the rail housings to guide the frontward and backward drawing in and out of the storage container, the rail members disposed between the plurality of rail supporting ends;a shaking prevention member coupled to a rear end of the storage container to prevent the storage container from shaking in a left and right direction; rack members enabling the pinions to be seated thereon and to move at lower sides of the rail housings, each said rack member being spaced from the lower ends of the rail housings; each said rack member comprising an upper surface, a lower surface, gear teeth extending upwardly from said upper surface, said gear teeth inter-engaged with the shaking prevention member; rack connectors, each rack connector extending downward from a lower end of one of the rail housings and being connected to the upper surface of one of the rack members;wherein the shaking prevention member comprises: a shaft horizontally coupled to a rear end of the storage container, an extension line of the shaft configured to cross the rack connector; andpinions rotatably coupled to both ends of the shaft, the shaft disposed lower than a lower side of the plurality of rail supporting ends; and higher than upper surface of the rack members. 9. The refrigerator as claimed in claim 8, wherein the storage container comprises at least one of a cold chamber drawer and a storage box provided on an upper side of the cold chamber drawer. 10. The refrigerator as claimed in claim 8, wherein the rack connectors are extended downward at a predetermined angle. 11. The refrigerator as claimed in claim 8, wherein each of the rail members comprises: a fixing rail fixed to the side of the storage space;a guide rail extendably coupled to the fixing rail; anda moving rail extendably coupled from the guide rail. 12. The refrigerator as claimed in claim 8, wherein each of the rack connectors extends inwardly from the rail housing.
