Specifically, a continuous elongated gap is formed between the peripheral edge of the window glass and the opening edge of the window opening of the vehicle body panel, and the elongated extruded member is formed in this gap. Wind molding is fitted and sealed. The wind molding is usually molded from an elastomer such as rubber or resin, and is inserted into the gap and fitted into a predetermined portion, and the gap is provided at the vehicle outer end of the leg. And a decorative portion that covers the vehicle from the outside of the vehicle. For such a wind molding, it is preferable to use a material having higher rigidity from the viewpoints of workability in attaching to the vehicle body panel side, posture retention, and the like.

On the other hand, it has been conventionally proposed that a side portion of the wind molding be provided with a groove for damming and draining rainwater on the windshield. For example,
JP-B-57-54416 and JP-A-63-2917.
21 (U.S. Pat. No. 4,757,660), JP-A 1-1.
95032 (U.S. Pat. No. 4,865,796), Japanese Patent Laid-Open No. 1-223018 and Japanese Utility Model Laid-Open No. 1-144109.
Publication (US Pat. No. 4,984,839), Japanese Patent Laid-Open No. 3-12
8721 publication. In an automobile wind molding having such a rainwater receiving groove, a portion that can be lifted up apart from the surface of the wind glass is constructed, so that it is particularly necessary to improve the rigidity of the material.

[0004]

However, in order to improve the rigidity of the wind molding, when the entire wind molding is molded with a high rigidity material,
There is a problem that the bending workability of the corner portion is deteriorated at the time of mounting. Proposals for bending the corners satisfactorily are disclosed in Japanese Utility Model Laid-Open No. 58-73014 and Japanese Patent Laid-Open No. 59-85.
No. 23 or Japanese Unexamined Patent Publication No. 60-248426, etc., the number of steps in molding and mounting the molding is increasing,
There is a problem in productivity, and there is also a problem that a large storage space is required because the storage is in a bent state during transportation. Further, JP-A-1-145223 (US Pat. No. 4,968,543) discloses an insert of an iron core to impart rigidity, but it requires a large mold and has the above-mentioned problem of transportability. .

Therefore, according to the present invention, it is possible to obtain good wearability and transportability while enhancing the rigidity of the molded portion of the rainwater receiving groove, that is, the portion separated from the windshield surface.
Moreover, it is an object of the present invention to provide an automobile wind molding that can be easily continuously molded and a method for manufacturing the same.

[0006]

In order to achieve the above object, an automobile wind molding according to the present invention has a window glass upper portion fixed to a window frame opening portion of a vehicle body panel, extending from a corner portion to both side portions. The main body molding is mounted along the peripheral edge of the windshield, and at least the main body molding in the side portion is separated from the surface of the windshield toward the outside of the vehicle, and the rainwater receiving groove is formed in the separated portion. In an automobile wind molding made up of, the entire length of the molding is made of a series of integrally formed extruded members, and at least the main body molding at the corner portion is made of a material having flexibility as compared with the side portion. ing.

Further, according to the method of manufacturing a window molding for an automobile according to the present invention, the window glass fixed to the window frame opening of the vehicle body panel is mounted along the peripheral edge from the upper side to the corner side to both side sides. The main body molding is formed by using an extrusion molding die, and at least the main body molding corresponding to the side portion is separated from the surface of the windshield toward the outside of the vehicle to receive rainwater between the surface and the windshield. In a method for manufacturing an automobile window molding, which is extrusion-molded so as to define a groove, the entire length of the molding is extrusion-molded integrally from an extrusion-molding die, at least at a corner portion. The main body molding is configured by extrusion molding using a material having flexibility as compared with the side portion.

[0008]

According to each means having such a structure, the rigidity of the rainwater receiving groove forming portion is enhanced by the hard material, and at the same time, the bendability at the corner portion is secured by the soft material. .

It is composed of a lip-shaped member that comes into contact with the vehicle exterior surface of the vehicle body panel 3. The glass side decorative portion 21a and the panel side decorative portion 21b are set to have a uniform thickness and shape over the entire length of the molding.

Here, the side molding 2C is made of a relatively hard material P1, and the corner molding 2B and the upper molding 2A are the side molding 2C.
The material P2 is more flexible than the material P1. As the material P1 having hardness, for example, a material in which glass fibers are folded is used.

A vehicle body side mounting structure of the window glass 1 using the main body molding 2 will be described below. The inner peripheral edge portions of the glass mounting openings provided in the roof panel 3 and the pillar panel 4 are bent in a stepwise manner toward the room side so as to receive the windshield 1, and the bent walls 3a and 4a are interposed therebetween. Flange portions 3b and 4b are provided. The rising height of the bending wall 3a of the upper part is uniform, but the rising height of the bending wall 4a of the side part is
It is gradually raised from the middle of the corner.

First, the sub molding 3 is mounted from the corner portion to the side portion of the main body molding 2 described above.
The sub-mold 3 is provided on the glass-side decorative portion 21 of the molding main body 2.
