A refrigerated case is shown that is equipped with a cooling room located in the storage room and cools the storage room by forcibly circulating the cold air that has been heat exchanged with the cooler in the cooling room through the storage room and the cooling room using a blower fan. .

(C) Problems to be Solved by the Invention According to the above-mentioned conventional technology, when the transparent door is rotated to open and close when storing the product in the storage room or taking out the product from the storage room, it is difficult to open and close the transparent door. There is a problem that the cold air in the storage room leaks to the outside due to the attractive force, and the cold air in the storage room leaks to the outside due to the pressing force due to the closing of the transparent door.

In order to solve this problem, a sliding type transparent door shown in the show case of Publication No. 52-2933 (70B24) can be used instead of a rotating transparent door. However, in order to change the specifications from a rotating type to a sliding type, it was necessary to change the shape of two of the four pillars, which required two types of molds with different shapes for the pillars. Not only does this increase the cost of parts, but also makes assembly work cumbersome due to misplacement of each support.In addition, a rail is formed on one edge of the bottom plate of the storage room to bear the load of the transparent door, making the bottom plate Problems arose, such as the need for measures to increase strength.

(d) Means for Solving the Problems In order to solve the above problems, the present invention provides a storage room whose peripheral wall is made of a transparent door and a transparent plate, and a heat insulating wall placed directly below the storage room. It is defined in
