According to this embodiment, the following effects can be obtained. In the louver system 1, the shaft member 23 constituting the louver 20 is pivotally supported at the center of the column 13 in the entering and exiting direction. Therefore, the number of members arranged in the functional space 10 can be reduced, and the original size of the functional space 10 can be reduced. Can be secured sufficiently.

Since the plurality of louvers 20 are simultaneously rotated by the connecting rod 60, the angle of each louver 20 can be easily adjusted, and the louvers 20 can quickly respond to a changing solar radiation angle.

Since the panel body 21 of the louver 20 is simply held between the mounting portion 24 of the support member 22 and the holding member 27, a fixed portion having a special shape may be provided on the panel body 21, or the panel body 21 may be provided. There is no need to surround the four circumferences with an edge member (frame member) or the like, and the panel body 21 can have a simple structure, and the louver 20 can be manufactured at low cost to reduce costs.

The convex portion 26 A of the screw portion 26 and the holding member 2
Since the holding member 27 is prevented from rotating around the bolt 28 by fitting the concave and convex portions 27A into the concave and convex portions 27A, the bolting of the holding member 27 can be performed easily and reliably. Further, since there is no possibility of rotation even after the holding member 27 is attached, it is possible to reliably prevent the panel body 21 from shifting in the long side direction.

Since the cushion member 29 made of rubber or the like is attached to the panel body 21, it is possible to prevent the panel body 21 from being damaged at the sandwiching portion, and to prevent the panel body 21 from slipping due to its large frictional resistance. Deflection in the side direction can be more reliably prevented.

Since the louver 20 is provided at a position that reliably blocks the solar radiation into the building A, the amount of solar radiation entering the building A can be adjusted, and the functional space 10 can be provided with a light-shielding property.

Since the louver system 1 is configured to include the solar cell panel 70, it can generate power using sunlight and can promote energy saving.
At this time, since the solar cell panel 70 is provided at a height that does not obstruct the view from the inside of the building A, a good view can be reliably ensured.
