  • the present disclosure provides a refrigerator that can enhance the heat insulating property of the rotating partition and can suppress warping, deformation, and the like due to the temperature difference of the rotating partition. Therefore, the present invention can be widely applied to refrigerators, cooling devices, and the like of various types and sizes such as home use and business use provided with a rotating partition.
