The present invention refers to a duct structure for refrigerator, which is characterized in that it comprises an insulating layer 105 placed between outer and inner housings 101 and 102, the same forming outer and inner surfaces of the refrigerator 100 respectively. A duct body 120 having a cold air path therein is assembled to the rear portion of the inner housing 102, where the insulating layer is located 105. The duct body 120 vertically extends along the inner housing 102 and presents a side thereof which is opened and facing said inner housing 102, both edges of said side include flanges 124 arranged in a longitudinal manner. The flanges 124 are portions that come into close contact with the rear portion of the inner housing 102, said both edges of the opened side or the portion of the duct body 120 are formed by means of fastening protrusions 126. The inner housing 102 is provided with a coupling orifice 103 that is perforated in order to allow a refrigerating chamber 107 and t he cold air path 122 to be in contact therebetween through the opened side of the duct body 120. The invention further includes a cover plate 130 that is attached to the duct body 120 by means of the coupling orifice 103 facing the inner housing 102; the rear portion of the cover plate includes coupling elastic ribs 134 and elastic arms 135, the same protruding from the tip portion of the ribs 134 to the rear portion of the cover plate 130 respectively; the tip portions of the elastic arms 135 are formed by a plurality of channeled slots 136 respectively.
