[0002]

2. Description of the Related Art A door structure of a vehicle generally has a structure in which parts such as an outer panel, an inner panel, a door window panel, a window regulator, and an interior trim are assembled (Nissan Motor Co., Ltd., June 1987).
Monthly Service Report, No. 578, page B-30). The inner panel is provided with work holes of various sizes, and the work is performed while screws and the like required for assembly are inserted into the door through the work holes.

[0003]

However, such a conventional technique has a structure in which the respective components are assembled with each other in a series of steps as described above. Accordingly, screwing work or the like from the inside of the door cannot be performed, so that work using the working holes increases, and difficult work is forced.

[0004] Further, since the structure is such that the individual components are attached independently of each other, the door window panel cannot be assembled or adjusted until all parts are assembled and the door is completed. When the door window panel is installed and adjusted, it is necessary to take account of the mounting error of each of the independently assembled components, so that the adjustment operation becomes difficult.

Further, conventionally, the adjustment of the installation of the door window panel has been performed based on the shape of the outer panel of the door. Therefore, the accuracy of assembling the door window panel may be adversely affected by the variation in the shape of the outer panel, so that a complicated adjustment work is required to correct it, which further complicates the door assembly work. And

The present invention has been made by paying attention to such a conventional technique, and provides a vehicle door structure in which the assembling work is easy and the installation and adjustment of the door window panel can be easily performed.
