The design surface 1 and the mounting surface 2 are located on both outer sides of the substantially V-shaped insert 3. The inside of the substantially V-shaped insert 3, that is,
The inner side sandwiched between the design surface 1 and the mounting surface 2 is an opening 4, and the opening 4 is formed so as to elastically clamp the end of the window glass 9.
The seal portion 5 at the tip, which is continuously formed on the design surface 1, comes into close contact with the window glass 9 when the end of the window glass 9 is held between the opening 4 to improve sealing performance and prevent water droplets, dust, etc. This is the part that prevents the intrusion of

In addition, when the entire surface of the design surface 1 is made of synthetic resin, or when the insert 3 is curved and exposed on a part of it, or a part of the surface is coated, vapor-deposited, or coated with a metal such as aluminum or chromium. In some cases, sputtered bright film is attached. The substantially V-shaped insert 3
For this purpose, strip-shaped aluminum thin plates, steel thin plates, stainless steel thin plates, etc. are used. In addition, its cross-sectional shape is approximately V
Depending on how it is used, the term "shape" refers to a case where it has bent parts arranged in parallel and is approximately V-shape, or a substantially U-shape, a substantially U-shape, a Y-shape, a U-shape. , it takes the form of a U-shape, etc.

This type of vehicle wind molding 10 mainly includes:
It is continuously molded by extrusion molding of synthetic resin.
Ordinary continuously molded vehicle window molding 10
In the opening 4, a sealing portion 5 at the tip, which is continuously formed on the design surface 1, clamps the end of the window glass 9 at the opening 4 and is brought into close contact with the window glass 9 to sufficiently develop sealing properties. The aperture is set to a level that allows the lens to shine brightly.

The continuously molded vehicle window molding 10 is
It is attached to the back window shown in FIG. 3, and cut into a predetermined length depending on the attachment state. In this embodiment, the vehicle window molding 10 disposed around the window glass 9 of the back window is the right vehicle window molding 10 on the right side when viewed from the rear.
