In order to connect the longitudinal-type steadying material 62, the base end member 50 and the transverse-type steadying material 61 are fixedly provided with a connecting member 70 with a hole in the shape of a square tube facing each other. The longitudinal-type steady rest member 62 is configured in the same manner as the beam member 60, and is provided with bifurcated pieces and pins at both ends, and the pin is connected to the connecting material 70 in a state where the connecting member 70 is sandwiched between the bifurcated pieces. By being inserted into the holes, they are detachably connected.

As can be understood from the above, the beam member 60, the transverse type anti-spinning member 61 and the longitudinal type anti-spinning member 62 have different lengths from each other, but the basic constituent members having the same configuration (square tube) Can be used, so that parts can be shared.

In the case of the illustrated embodiment, as shown in FIG. 8, the closing plate 58 held in the holding grooves 54 of the left and right frames 51 </ b> L and 51 </ b> R is constrained by the beam member 60 and the steadying members 61 and 62 from above and below. Therefore, even when the closing plate 58 formed of a thin flexible plate such as FRP is bent and deformed, for example, by strong wind, it can be suitably prevented from falling off the holding groove 54.

The corner morning glory device 19 installed in the corner region via the corner bracket 22 aligns the obstruction plate of the rectangular morning glory device 20 and the upper surface of the obstruction plate 58 of the fan-shaped morning glory device 21 that constitute the corner unit. At this time, as shown in FIG. 10, the fan-shaped morning glory device 21 overlaps the wing piece portion 55 of the frame 51 above the side edge of the rectangular morning glory device 20, thereby preventing the generation of a gap. As described above, the frame 51 including the opposite wing piece portion 55 is disposed at a predetermined position H above the adjacent end morning glory device 2e, and forms a vertical clearance h that does not interfere with each other.

The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment. For example, the rectangular morning glory device 20 and the fan-shaped morning glory device 21 constituting the corner unit are vertically arranged. It is not always necessary to arrange them, and the object of the present invention can be achieved as long as the fan-shaped morning glory device 21 is installed at a predetermined upper position H so as not to interfere with the adjacent end morning glory device 2e. Moreover, although the said embodiment demonstrated the structure which supports the rectangular morning glory apparatus 20 from the downward direction by the diagonal material 24, the support method of the rectangular morning glory apparatus 20 can change a design suitably etc. suitably. Further, the meaning of the “fan shape” of the fan-shaped morning glory device 21 is not limited as long as it can close the space in the range of the angle θ described above, and includes various shapes in addition to the isosceles triangle as illustrated. I want you to understand that.
