6, and is fixed to the closing plate 34.

Reference numeral 47 denotes a drain tank provided slidably in the front and back direction in the space below the machine room bottom plate 31. A drain receiving hole _47A1 is formed in the upper wall 47A of the drain tank, and the storage room bottom plate covers the upper surface of the base 4. A drainage hole 48A formed at the lowest part of the drain hole 48A, an opening 31A formed in the machine room bottom plate 31 directly below this drainage hole 48A, and the drainage receiving hole 47 formed immediately below the opening 31A.
Defrosting water and the like drips into the drain tank 47 through _A1 . The lower parts of the storage room 2 and the machine room 3 are bolted into openings formed in the bottom plate 4A that covers the lower and side surfaces of the base 4, the board reinforcement material 4B, and the machine room bottom plate 31, respectively.

and a connecting plate 49 bent outward at a right angle from the tip of the side plate on the storage chamber 2 side.
It is composed of B. Further, an extending portion 22A having a reduced cross-sectional area and extending toward the machine room 3 side is formed in advance at the end of the reinforcing member 22 provided on the upper surface of the storage room 2 in the left-right direction on the machine room 3 side. There is. The extension portion 22A includes a first vertical wall 22A ₁ extending vertically downward from the tip of the reinforcing member 22, and a first vertical wall 22A 1 bent horizontally at right angles toward the machine room 3 from the lower end of the first vertical wall 22A ₁ . The horizontal wall 22A ₂ that extends
A second vertical wall 22A ₃ extends vertically downward from the end of the wall 2A 2 on the machine room ₃ side. First and second openings 49B' and 22A3' are formed facing each other in the connection plate 49B and the second vertical wall _22A3 for communicating a connection member ₅₁ such as a screw. The opening 22A ₃ ′ is formed with a female acme screw that fits with the male acme screw of the connecting member 51, and the connecting member 51 is connected to the first and second openings 49B′ and 22A ₃ ′ and tightened in the direction of the arrow 52A″. The upper part of the storage chamber 2 is pulled in the direction of the arrow 52B'', and the storage chamber 2 and the machine room 3 are connected. Therefore, the reinforcing material 22 can be used as a connecting member, and there is no need to attach an assembly member 49 such as the machine room 3 to the storage room 2, which reduces the number of parts required for connection and simplifies the connection work. can be converted into Furthermore, the extension portions 22 of the reinforcing members 22, 22
Since A and 22A are drawn and connected to the partition wall 33 via the assembly members 49 and 49, respectively, the strength of the frame of the storage chamber 2 can be improved. Furthermore, since the extending portion 22A and the assembly member 49 are tightened in the direction of the arrow 52 by the connecting member 51, the gap between the connection between the storage chamber 2 and the machine room 3, for example, the gap between the front end of the upper surface of the partition wall 33 and the partition plate 11, is reduced. It is possible to reliably eliminate this and improve sealing performance.

As described above, the present invention is a connection device for a show case that connects a storage room and a machine room to each other, and the reinforcement is inserted into a cavity in the upper frame of the opposing storage room and has one end extending into the machine room. connection of a show case consisting of a material, an assembly member installed in a machine room facing the reinforcement member, and a connecting member that penetrates the assembly member and is screwed to the reinforcement member to tighten both. Since it is a device, the strength of the frame of the storage room can be improved, and the sealing performance of the connection between the storage room and the machine room can be improved.
