Furthermore, in this embodiment, although the convex parts 35, 36, and 37 of the vortex generating member 20 are integral members, they may be separate members, and the same effect can be obtained.
- the sunroof device and the deflector according to the present invention can effectively suppress the inflow of wind into the vehicle interior when traveling with the roof opened, and can also reduce noise generated by the wind colliding with the vehicle roof. Suitable for vehicles having an opening in the roof.
