As a measure against snowfall, for example, the louver member 20
Although it is considered that the cross section of the louver is difficult to fall as a snow mass, it is necessary to consider a member that does not deteriorate the functions such as ventilation, dimming, and sound insulation required for the louver. If the louver is formed into a shape for preventing snowfall or a member for preventing snowfall is attached, the function required as a louver is inevitably reduced, and the determination of the shape and dimensions of the louver member and the selection of the mounting position are troublesome.

In particular, if the louver member 20 has a bent portion, the opening width W between the louver members 20, 20 becomes too small, which causes a decrease in ventilation, ventilation function, dimming, and sound insulation function. There is a problem in that dust adheres to the louver 20 and debris such as fallen leaves are clogged between the louver members 20, thereby impairing the function of the louver. There were problems such as an increase in cost.
