The two main bodies 10 and 10 can be easily connected to the left and right.

The present invention is not limited to each of the above-described embodiments, and includes various other modifications. For example, in the second embodiment, the two main bodies 10 and 10 are left and right. Although they are connected, three or more main bodies may be connected to the left and right. Further, in the third embodiment, the two main bodies 10 and 10 are connected vertically, but three or more main bodies may be connected vertically. Further, in the fourth embodiment, two of the three main bodies and the other main bodies 10 and 10 are connected to the left and right, and the remaining one main body 10 is connected to the one main body 10 up and down. Needless to say, four or more main bodies may be connected vertically and horizontally.

Further, in each of the above-described embodiments, the length of each support column 21 in the front-rear direction is set to about 12% of the length of each shelf board 11 in the front-rear direction. The length in the front-rear direction of each support column on the front side of the shelf may be set to be 7 to 29% of the length in the front-rear direction of each shelf board in the front-rear direction. Specifically, the length of each support column in the front-rear direction is set to 30 mm to 120 mm, while the length of each shelf board in the front-rear direction is set to 417 mm, and the length of each shelf board in the front-rear direction is set. However, it may be about 7 to 29% of the length.

Further, in the third and fourth embodiments, the shelf board 52 with a hole is not installed in the upper frame portion 14 of the other main body located on the lower side of the upper and lower main bodies, but the other A shelf board with a hole may also be installed in the upper frame portion of the main body. In that case, the distance between the shelf board with a hole in the lower frame part of one of the main bodies located on the upper side and the shelf board with a hole in the upper frame part of the other main body located on the lower side is narrow and the direction of the cat. Since it cannot be converted, it is necessary to install a shelf board with a hole in which the holes are aligned with each other, although the shelves with both holes are adjacent to each other in the vertical direction. Furthermore, if a shelf board with a hole is also installed in the upper frame portion of the other main body, it is necessary to newly install a shelf board in the upper frame portion of the other main body when changing the arrangement of the main body. It will be very advantageous to implement.
