The joining member 60 is made of a metal plate having substantially the same thickness as the movable engaging portion 31. When the movable engagement portion 31 is disposed at the engagement position 35, the gap between the circumferential surface Sf of the second support column S2 and the movable engagement portion 31 is filled with the joining member 60. This prevents the lateral displacement of the width timber 10 and reduces the possibility that the engagement with the columns S1 and S2 will come off and fall off. Further, rattling of the movable engaging portion 31 is suppressed, and generation of noise or the like can be prevented.

  In the case where the joining member 60 is provided in the movable engaging portion 31, a cutout portion 38 is formed in the movable engaging portion 31 as shown in FIGS. When the movable engaging portion 31 overlaps the width timbers 10 at the engagement release position 36, as shown in FIG. 4, a part of the joining member 60 of the other width timber 10 on the movable side notch portion 38. Is inserted. Thereby, interference with other width | variety timber is avoided, it becomes a space saving, and conveyance and storage cost are suppressed. Moreover, since the movement of the rotation member 30 is restricted when the width timbers 10 are overlapped with each other, the rotation member 30 does not move during transportation, which is safer.

  Then, as shown in FIG. 5, the fixed engaging portion 21 may be formed with a fixed-side notch portion 28. In addition, the reinforcing plate member 80 is formed in a substantially U shape when viewed from the side, so that when the width timbers 10 are overlapped with each other, the reinforcing plate member 80 of the other width timber 10 is placed on the fixed-side notch 28.
