Description of the Related Art Conventionally, a glass run channel of this type has an upper channel portion along an upper portion on an inner peripheral surface of a window frame of a vehicle door, a corner channel portion along a corner portion on an inner peripheral surface of the window frame, and a window. Mainly composed of side channel parts along both sides of the inner peripheral surface of the frame, the upper channel part, the corner channel part and the side channel part respectively have a base part and a side wall part to form a glass sliding groove. It has been generally formed to have a channel shape in cross section. Further, in such a glass run channel, when the upper channel portion, the corner channel portion and the side channel portion are continuously and integrally formed in a straight line by extrusion molding, the corner channel is formed along the corner portion of the inner peripheral surface of the window frame. When the part is bent, both side walls of the corner channel part are expanded due to the bending stress, which makes it difficult to fit the inner peripheral surface of the window frame into the corner part and also causes the corner channel part to be wrinkled or wavy. Deformation occurs and the appearance becomes poor. Therefore, conventionally, as shown in FIG. 7, the upper channel portion 12 'and the side channel portion 14' are formed by extrusion molding, and the corner channel portion 13 'is formed by injection molding or press molding. Then, the upper channel portion 12
There is a glass run channel 10 'configured by joining a total of five parts, namely, a corner channel portion 13' and a side channel portion 14 '.

[0003]

By the way, in the conventional device shown in FIG. 7, the number of constituent parts is increased, the manufacturing and assembling costs are increased, and the upper channel portion 12 'and the corner channel portion 13' are also provided. In addition, there is a problem in that the appearance is deteriorated due to the difference in hue between the side channel portions 14 'and the seam formed at the joint. In view of the above-mentioned conventional problems, an object of the present invention is to manufacture and assemble a glass run channel body that integrally includes an upper channel portion, a corner channel portion, and a side channel portion by extrusion molding. An object of the present invention is to provide a glass run channel for a vehicle door capable of reducing the attachment cost and preventing the both side wall portions from being expanded or deformed abnormally due to the bending of the corner channel portion.

[0004]

In order to achieve the above-mentioned object, the present invention is a glass run channel which is fitted into an inner peripheral surface of a window frame of a vehicle door and which guides a door glass up and down. And an upper channel portion, a corner channel portion, and a side channel portion having a substantially channel-shaped cross section having both side wall portions provided on both side edges of the base portion so as to face each other with a glass sliding groove therebetween, are continuously formed. A channel body integrally provided was formed by extrusion molding, and a flexible holding member was attached to the corner channel portion of the channel body to restrain outer surfaces of both side wall portions thereof.

[0005]

In the glass channel of the vehicle door constructed as described above, when the glass run channel is mounted on the inner peripheral surface of the window frame, the holding member is previously attached to the corner channel portion of the channel body. Then, while bending the corner channel portion of the channel body corresponding to the corner portion of the inner peripheral surface of the window frame, the channel body is fitted into the inner peripheral surface of the window frame. When the corner channel portion of the channel body is bent and fitted into the corner portion of the inner peripheral surface of the window frame, the outer surfaces of both side wall portions of the corner channel portion are restrained by the holding member, and the both side wall portions are expanded. The troubles that are caused are prevented. Furthermore, since the holding member has flexibility,
The corner channel portion is smoothly bent along the corner portion on the inner peripheral surface of the window frame.
