FIG. 23 is a plan view of the corner member 20 of the container 1 arranged in the upper stage when the container 1 is fixed by being coupled to another container 1 using bolts.

As shown in FIGS. 21 to 23, when a plurality of containers 1 are stacked in the vertical direction and the adjacent upper and lower containers 1 are connected and fixed, through holes 21 a to 21 a provided in the corner member 1020 of the lower container 1. 21c and the through holes 21a to 21c provided in the corner member 20 of the upper container 1 correspond to each other, and the bolt 170 fitted with the washer 171 from the through holes 21a to 21c provided in the corner member 1020 of the lower container 1 Through. Thereafter, a washer 171 is fitted to the bolt 170 protruding from the through holes 21 a to 21 c provided in the corner member 20 of the upper container 1, and tightened with the nut 142. By fastening three bolts 170 at each of the four corner members correspondingly overlapping between the upper and lower containers 1 adjacent to each other, the containers 1 arranged above and below are coupled and fixed.
The three through holes 21a to 21c are fixed at three positions through the bolts 170, but the two through holes 21a to 21c may be fixed at two positions through the bolts 170 at two positions. Of course.

As described above, the corner member used in the container of the present embodiment has a hollow portion and a hole through which a fixture provided in a crane hook and transfer means is moved in and out of the container, and has a transfer function.
Furthermore, the corner member has a through hole used for fixing the container at the time of storage of luggage at a fixed place on land in addition to fixing the container at the time of transfer, and has a fixing function.
In the present embodiment, the corner member is formed as a lump having a hollow portion and a hole for providing a transfer function, and is provided with a flange portion integrally having a through hole rather than protruding. Thereby, compared with the case where the part which protrudes and has a through-hole is provided, the fixed strength between the laminated | stacked upper and lower containers can be strengthened more.
Furthermore, since the corner member is a lump and is welded to the three column beams of the container, the fixing strength between the corner member and the container body is high. Moreover, since the corner member is shaped like a lump, it is possible to eliminate as many projections as possible in the container state. Thereby, it can reduce as much as possible that a projection part damages at the time of transfer, and can ensure the work safety at the time of transfer.
