However, in snowy areas,
For example, as shown in FIG. 9B, the louver member 20
The snow accumulated on the road may become a large snow mass 21 and fall onto the road, sometimes directly hitting a running vehicle, which is a major safety issue.

As measures against snowfall, for example, the louver member 20
Although it is considered to make the cross-sectional shape of the louver difficult to fall as snowflakes, it is necessary to consider a member that does not reduce the functions such as ventilation, dimming, and sound insulation required for the louver. If the shape of the louver is taken as a countermeasure against snowfall, or if a member for a countermeasure against snowfall is attached, the function required as a louver is unavoidably deteriorated, and it is troublesome to determine the shape and size of the louver member and the attachment position.

In particular, when the louver member 20 has a bent portion, the opening width W between the louver members 20 and 20 becomes too small, resulting in deterioration of ventilation, ventilation function, dimming, and sound insulation function. There is a problem that the function of the louver is hindered because dust adheres to the louver 20 or dust such as leaves falls between the louver members 20 and 20.
Further, in manufacturing, there is a problem that the processing becomes troublesome and the manufacturing cost increases.

The present invention has been made in order to solve the above problems, and it is possible to prevent the falling of snow blocks while maintaining the functions of light control, sound absorption, sound insulation and ventilation required for the louver. It is an object to provide a louver unit for a vehicle traveling path.
