The cross bar 21a may have a plurality of vertical bars 21b installed vertically as shown, or a normal perforated panel, not shown, may be installed.

As shown in solid and broken lines in FIG. 3, the fixing unit 30 fixes the end of the above-described cross bar 21a to the support 10 so that it can rotate uniaxially. For example, as shown in FIG. 4, the fixing unit 30 may be composed of the above-described hinge shaft, the hinge ring 31, and a connector described later.

The hinge shaft may be composed of a hollow pipe 34 as shown in FIG. 4. As shown in FIG. 5, one end of the hollow pipe 34 is fixed to the strut 10, and the other end protrudes to the outside of the strut 10. One end of the hollow pipe 34 may be fixed to the outer peripheral surface of the support 10 by welding. In contrast, as shown in FIGS. 4 and 5, the hollow pipe 34 has one end inserted into the support 10 through the through hole 10a of the support 10 and then fixed to the support 10 by bolting. It may be possible. For this purpose, the hollow pipe 34 is equipped with a nut 34c having a female thread on the inside of one end, as shown in FIGS. 4 and 5. The nut 34c can be configured to be fixed to the hollow pipe 34 by being pressed by a bead 34a formed in a depressed state on the outer peripheral surface of the hollow pipe 34 as shown by beading processing. At this time, the beadings 34a are preferably formed to be spaced apart along the outer peripheral surface of the hollow pipe 34 as shown.
