The heat-insulating box 101 is, for example, an outer case 102 made of stainless steel, which is opened to the front, an inner case 103 made of stainless steel, which is also opened to the front, and heat insulation such as foamed polyurethane foam-filled between the outer case 102 and the inner case 103.

A slope (not shown) for loading and unloading the cart is attached, but since the slope angle of this slope cannot be made too steep, conventionally, the bottom plate 1 of the outer box 102 is generally used.
02A and the bottom wall 101 including the bottom plate 103A of the inner box 103
The thickness dimension of A was set to about 20 mm. However, with such a thickness, the space between the bottom plate 102A of the outer box 102 and the bottom plate 103A of the inner box 103 is only 10 mm, which makes it extremely difficult to foam-fill the heat insulating material 104.

A had the structure shown in FIGS. That is,
On the upper surface of the bottom plate 102A of the outer box 102, the reinforcing angles 109 and 11 at the periphery and the center which are assembled by welding with each other.
0 is fixed by spot welding, and a heat insulating member 111 such as a waterproof veneer plate is attached by adhesion between the reinforcing angle 109 and between the reinforcing angles 109 and 110. In this case, the surrounding reinforcing angle 109 including the front part has a substantially U-shaped cross section open to the upper surface,
The heat insulating member 111 is attached inside thereof.

The steel plate 112 protects and reinforces the bottom plate 103A of the inner box 103 with which the wheels of the cart are in contact, and its upper surface is flush with the upper surface of the heat insulating member 111. Then, an adhesive or an adhesive tape is applied to the upper surfaces of the reinforcing angles 109 and 110 and the heat insulating member 111,
By bonding the bottom plate 103A of the inner box 103 from above, the bottom wall 101A of the heat insulating box 101 is formed. Then, the bottom wall 101 is attached to the side plates of the outer box 102 and the inner box 103.

接構造であるため寸法上の誤差が生じ易く、また、底板
１０２Ａにもスポット溶接にて固定されている関係上、
断熱部材１１１の接着も不十分となり易い。As described above, the conventional reinforcing structure of the bottom wall 101A of the heat insulating box 101 is extremely complicated, and its weight is heavy, which is one of the factors that hinder the improvement of the assembling workability. On the other hand, since the reinforcing angles 109 and 110 have a welded structure, a dimensional error is likely to occur, and because they are also fixed to the bottom plate 102A by spot welding,
Adhesion of the heat insulating member 111 tends to be insufficient.

み合い等を現場で調整しなければならなかった。Therefore, the rigidity of the bottom wall 101A cannot be sufficiently ensured, and in particular, the rigidity of the opening portion (front portion) is insufficient, and when the storage is installed, the bottom wall 101A is deformed. It was necessary to adjust the engagement of the sheath (locking device) etc. on site.
