As an example thereof, there is a window regulator described in Japanese Utility Model Laid-Open No. 58-17473. This is a bracket which slides along a vertically arranged guide rail and to which a window glass is fixed, and is stretched between the upper and lower ends of the guide rail via a guide member and a cable guide, and It is composed of a cable member connected to the bracket, and a drive device having both ends thereof connected to drive the cable member. The drive shaft of the drive device is rotated by an operating lever to move the cable member. By moving, the window glass is moved up and down through the bracket connected to the cable member.

(Problems to be solved by the invention) By the way, when the window regulator device is used to move up and down the window glass as described above, it is necessary to reliably stop the window glass at the upper limit position in the ascending stroke and the lower limit position in the descending stroke. There is. In this case, when the window glass rises, the window glass
The door frame that is integrally provided on the upper part of the door panel to form a window or the stopper member provided on the window regulator itself will surely be stopped at the upper limit position, but when descending, In order to surely stop the windshield at the lower limit position, for example, a stopper member for surely stopping the windshield at the lower limit position is attached to a window regulator, or the stopper member is an outer panel or an inner panel constituting a door. It was necessary to assemble it in the predetermined position. For this reason, the number of parts increases, and the assembling work for assembling the stopper member must be performed, which requires a lot of labor.

The present invention addresses the above-mentioned problems, and a guide member for vertically guiding a guide roller supported by a window glass interposed vertically between an inner door panel and an outer door panel that constitute a door is provided on the door panel. In the vehicle door structure described above, the downward movement of the window glass is restricted at the lower limit position by using the bracket for attaching the guide member to the door panel, thereby increasing the number of parts and the assembly process. Moreover, it is an object of the present invention to provide a door structure in which the window glass is always stopped at the lower limit position accurately and reliably at a predetermined position.

(Means for Solving the Problems) In order to achieve the above object, the present invention is characterized in that it is configured as follows.

That is, there is provided a window glass vertically movably interposed between the inner and outer door panels forming the door, a guide roller supported by the window glass, and a guide member for vertically guiding the guide roller. In a vehicle door structure, the guide member is fixed to a door panel via a bracket, and a lower portion of the guide member is fixed to the door panel by a fixing portion to the door panel and a fixing portion from the fixing portion to the guide member. A stopper portion that extends downward to the vicinity of the lower end position thereof, abuts against the guide roller at the position, and restricts the downward movement of the window glass at the lower limit position, and further includes the fixing portion and the stopper portion,
It is characterized in that it is arranged on the same axis as the guide locus of the guide roller in the guide member.

(Operation) According to the above configuration, the guide roller supported by the windshield is vertically guided along the guide member fixed to the door panel via the bracket, whereby the windshield is moved up and down. It will be. Since the bracket for fixing the lower portion of the guide member to the door panel is provided with a stopper portion that comes into contact with the guide roller and restricts the downward movement of the windshield at the lower limit position, the stopper is provided. By locking the guide roller to the portion, the window glass can be reliably stopped at the lower limit position. In this case, the bracket is formed with high dimensional accuracy because it is necessary to arrange the guide member with high precision. Therefore, by integrally providing the bracket with the stopper portion, the restriction position at the lower limit of the window glass is The accuracy is also high. As described above, according to the present invention, the bracket provided in advance for fixing the guide member to the door panel is provided with the stopper portion for restricting the downward movement of the window glass at the lower limit position. Therefore, it is possible to accurately set the lower limit position without increasing the number of parts and the assembling process.

Further, particularly in the present invention, since the fixing portion of the bracket to the door panel and the stopper portion are arranged on the same axis as the guide locus of the guide roller of the guide member, the guide roller impacts the stopper portion. Even if they come into contact with each other, the fixed portion is located above the line in the abutting direction, so that a bending load or moment is not generated in the stopper portion or the bracket due to the abutment. Bending and deformation are prevented from occurring, and the high accuracy of the lower limit position is maintained for a long period of time.
