Since A and the rear legs 10B and 10B are inserted into the connecting surface 22, the displacement of the connecting surface 22 due to the movement of the show case A' can be suppressed to a very small extent. Further, the front surfaces of both the left and right front connecting portions 22A are covered by the sash 19, so that the front surfaces of the left and right front connecting portions 22A are not directly visible from the front, which is preferable from a design point of view, and creates a sense of unity between the two cases. Also, front legs 10A, 10A
Since the rear legs 10B and 10B protrude downward from the upper case 1, when the upper case 1 is temporarily installed on the floor during movement or transportation, the lower side edges 1B and the four corners of the lower surface directly come into contact with the floor. This protects the painted surface and prevents scratches from occurring.

Furthermore, a fastener 2 such as a bolt is attached to the connecting plate 20, 20 at the rear wall connection part between the upper case 1 and the lower case 5.
1, 21..., the rear wall connection part of the upper case 1 and the lower case 5 is fixed, and the rear wall connection part of the upper case A' and the lower part of the upper case 1 are fixed due to vibration or shock during movement and transportation. This can prevent the case 5 from shifting slightly from the rear.

As described above, the present invention has a pair of front and rear legs that protrude downward on the lower surface of the left and right side walls of an upper case equipped with a transparent door that rotates in the front and back directions on the front. The rear half of the upper surface of both left and right walls of the lower case has a transparent door that slides forward and backward in the front half of the upper surface, and a space that serves as a door storage section in the rear half of the upper surface, and is connected to the space and is opposite to the leg. A pair of front and rear notches facing each other and into which the legs are loosely fitted are formed, and a connecting tool is installed in which holes are formed above the left and right side walls of the lower case so as to face the holes in the front wall of the front legs. the front leg and the connector are connected within the space by fitting the leg into the space through the notch, and connecting the front leg and the connector in the space, and attaching a sash to the first half of the upper surface of the left and right side walls of the lower case. Since it is attached to cover the connector and the front connecting parts of both cases, when the upper case is placed on the lower case, the front and rear legs become positioning members with respect to the notch, and the door storage part is inserted through the notch. The front leg placed in the space serves as a connecting member for the connector placed in the same space, so the work to connect the upper case and the lower case must be done in the space that serves as the door storage area of the lower case. This can be done extremely easily and in a short time using a ready-made space. Furthermore, the weight of the upper case is distributed and supported by the upper wall of the lower case as the legs fit loosely, and no gap is created at the connection between the upper case and the lower case. Furthermore, since both the front and rear legs fit loosely into the notch, and the front legs and the connector are fixed within the space, the upper case may shift from the lower case when vibrations, shocks, etc. are applied to the show case due to movement, etc. can be prevented. Furthermore, since both the left and right front connecting portions are covered by the sash, the front surfaces of the connecting portions are not directly visible, and there is no protrusion on the left and right side walls of the connected show case, creating a sense of unity between the two cases, which is also desirable in terms of design.
