REFRIGERATOR

PROBLEM TO BE SOLVED: To ensure cold air seal between a refrigeration chamber and a third chamber without mounting a bottom plate, to reduce the inner size of the inner box of a third chamber having a food containing case positioned therein during foam-molding of urethane, to prevent the change of opening closing operation of a food containing case even when a U-groove is molded in a small size; and to prevent the occurrence of a hindrance on input and output of foods. SOLUTION: The two sides of a food containing case 32 in a third chamber 4 make linear contact with the ridge line of the lower end of a side flange 37 and the support part 23 of an inner box and sealing is effected to prevent leakage of cold air. Further, the rear part of the food containing case 32 is located in the vicinity of the lower end of a rear flange and the front of a temperature regulation device 9 and a support rib 24 arranged at the front of a temperature regulation device 9. A slight gap of approximate 1 mm is provided therebetween, no change occurs to opening and closing operation of the food containing case 32, and no obstacle occurs to input and output of a food. Further, seal of cold air is ensured between a refrigerating chamber 3 and a third chamber 4 without a conventional bottom plate.
