Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to an automobile window molding that is installed so as to seal a gap between the peripheral edge of a window glass fixed to a window opening of an automobile body panel and the automobile body panel, and the like. Regarding the manufacturing method.

2. Description of the Related Art Generally, a window molding is attached to the peripheral edge of a window glass attached to a window opening of a vehicle body panel. Specifically, a continuous long gap is formed between the peripheral edge of the window glass and the opening edge of the window opening in the vehicle body panel, and within this gap,
A window molding made of a long extruded member is inserted and sealed. This window molding includes a leg portion that is inserted into the gap, and a decorative portion that covers the gap from the outside of the vehicle.

In such automobile window moldings, it has been proposed in Japanese Utility Model Publication No. 57-54416 to form grooves for draining rainwater on the window glass. In this case, the grooves are preferably provided only in necessary parts from the viewpoint of preventing wind noise and increasing rigidity. On the other hand, since the water flow rises above the window glass when the vehicle is running, the lower end portion of the side molding may have a relatively small cross-sectional area. For these reasons, in the window moldings described in Japanese Utility Model Publication No. 62-15044 and Japanese Utility Model Application Publication No. 59-31513, grooves are provided only in the upper region or the lower region of the side portion.

[Problems to be Solved by the Invention] However, the grooves in the above-mentioned publications have a constant cross section in the longitudinal direction of the window molding, which poses problems in the water conductivity and drainage of water received in the grooves. It is occurring. Furthermore, a window molding having such grooves cannot be molded in a series using commonly used extrusion techniques. In other words, injection molding may be considered for molding the groove portion, but in that case, the entire length of the window molding must be made up of a plurality of connecting members. Furthermore, in this case, the mold becomes larger and the number of steps increases, resulting in a decrease in productivity. Note that the above-mentioned publications do not disclose how to form the grooves.

SUMMARY OF THE INVENTION An object of the present invention is to provide a window molding for an automobile and a method for manufacturing the same, which allows a window molding with good drainage function to be obtained using a simple device.
