However, the directions may be changed as appropriate depending on the usage conditions and the like.

The battery box 2 is a unit that supports a plurality of air batteries 10 (see FIGS. 7 and 8 described later). By exchanging the battery box 2, a plurality of air batteries 10 can be exchanged together. This battery box 2 supports a plurality of air batteries 10 together, and has an arbitrary structure applicable to a range including a structure in which at least a part of each air battery 10 is exposed.

The battery storage box 1 includes: an inner box 3 for detachably accommodating the battery box 2; and an outer box 4 that surrounds the inner box 3 with an air-insulated space to surround the inner box 3; and plastic Corrugated board. Plastic corrugated board is a thin sheet with a hollow structure made of polypropylene. It is a material that is impervious to water, lightweight, and easy to bend.

Each component constituting the battery storage box 1 is manufactured by cutting a plastic corrugated board and bending it appropriately. In addition, the parts are joined to each other by heat-sealing or a known fixing member (shown by reference numeral 5 in FIG. 1) such as a plastic rivet or a jig. Therefore, compared with the case where the battery storage box 1 is made of metal, a desired strength can be obtained and the weight can be reduced, and an initial cost such as a mold cost such as a resin molded product can be avoided.

The inner box 3 is a rectangular box formed with an upper opening, and includes a rectangular plate-shaped bottom plate 3A that is horizontal to the ground G, and rectangular plate-shaped side walls 3B that are erected from the bottom plate 3A to surround the battery box 2 from front to back.
The outer box 4 includes a rectangular box body 4A opened upward, and a cover body 4B that covers the box body 4A from above and can be opened and closed freely. The box body 4A is supported by a plurality of feet 4C so as to float from the ground G. As shown in FIG. 1, the cover body 4B is joined to the box body 4A by a plurality of fixing members 5, and a part of the cover body 4B is bent, so that it can be opened and closed without providing other hinge parts.

The box 4A of the outer box 4 includes a rectangular plate-shaped bottom plate 5A that is horizontal to the ground G, and a rectangular plate-shaped side wall 5B that is erected from the outer periphery of the bottom plate 5A. The bottom plate 5A of the outer box 4 and the bottom plate 3A of the inner box 3 may be the same component, or may be separate components. Hereinafter, for convenience of explanation, the bottom plate 3A of the inner box 3 is labeled as "inner bottom plate 3A", and the side wall 3B of the inner box 3 is labeled as "inner side wall 3B".

As shown in FIG. 2, the inner side wall 3B includes an inner front wall 3F, an inner rear wall 3G, an inner left wall 3L, and an inner right wall 3R, which are located at the front, rear, left, and right sides of the battery box 2.
The side wall 5B of the outer box 4 has a front wall 5F provided with a gap S1 from the inner front wall 3F and a rear wall 5G provided with a gap S2 from the inner rear wall 3G, and A gap S3 is left between the inner left wall 3L and the left left wall 5L, and a gap S4 is left between the inner right wall 3R and the right wall 5R.

The space corresponding to each of the gaps S1 to S4 becomes a cavity, and each cavity is filled with air. Accordingly, the space corresponding to each of the gaps S1 to S4 is a heat-insulating space that obtains a heat-insulating effect by air. Hereinafter, the spaces corresponding to the gaps S1 to S4 are referred to as heat-insulating spaces S1 to S4.

FIG. 3 is a view of the battery storage box 1 in a state where the lid body 4B is viewed from above. The battery box 2 is omitted in FIG. 3.
As shown in FIG. 3, since the heat insulation spaces S1 to S4 are formed throughout the front, back, left, and right of the inner box 3, the temperature rise in the inner box 3 due to the influence of direct sunlight and the like can be suppressed. Thereby, the temperature rise of the battery case 2 in the inner case 3 can be suppressed. Moreover, even in winter and summer, the temperature inside the inner box 3 can be made more stable than the outer space.

The cover 4B is formed larger than the outer case 4 in a plan view of the battery storage case 1. Thereby, the cover 4B is closed to prevent the invasion of rainwater and the like from above, and a gap for air in and out can be secured between the cover 4B and the outer box 4 (equivalent to a part of the gap 8D in FIG. 5 described later). Wait).
