As a result, the left first coupling plate 262 and the second coupling plate 261 are bent into a U shape, and the inner vertical plate 140 of the left edge is inserted into the space between them and joined. At this time, the width of the left first coupling plate 262, that is, the height when bent, is formed to be the same as the width of the inner vertical plate 140, so that the left first coupling plate 262 and the second coupling plate 261 are in contact with each other.
