[Detailed description of the invention] (Industrial application field) The present invention relates to automobile doors.

(Prior art) Conventionally, the adjustment of building materials for automobile doors was carried out using
As seen in Japanese Patent No. 01, this was supposed to be done by a hinge connecting the door and the body.

That is, conventionally, the main body of an automobile door is generally formed by joining an inner panel and an outer panel on three sides excluding the waistline. For this reason, the assembly of door interior parts to the door body is now done using the many work holes provided in the inch panel, and the adjustment of the building materials, that is, the gap adjustment between the body and the door. This was done by adjusting the position of the door hinge that connects the door and the body.

(Problems to be Solved by the Present Invention) For this reason, when using conventional doors and methods for assembling the same, the following problems occur in the adjustment work of door building materials.

(1) The position of the door hinge must be adjusted within the small gap between the door and the body, so the work space is small.

(2) In addition, the lower hinge position adjustment work must be done with the door open in order to create a working space, and the door must be opened and closed many times to check the condition of the door construction materials. Must be.

(3) When adjusting the position of the door hinge, extreme care must be taken to avoid damaging the outer panel.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an automobile door and a method for assembling the same, in which door construction materials can be easily adjusted.

(Means and effects for solving the problem) The present invention takes into consideration the fact that the original purpose of door construction material adjustment is to adjust the gap between the body and the outer panel, and adjusts the construction material using this outer panel. In this way, there is no need to adjust the position of the door hinge in a narrow working space sandwiched between the body and the door, as in the conventional case.

Specifically, as an automobile door, an inner panel and an outer panel are assembled to a skeleton to which door interior parts are attached, and the outer panel is adjustable in relative position with respect to the skeleton or the inner panel. There is.

In addition, the assembly method is to assemble the inch panel to the skeleton to which the door interior parts are attached, then mount it on the car body, and then install the outer panel whose position can be adjusted relative to the skeleton or the inner panel. The outer panel is assembled while adjusting the building materials.

With this configuration, first, according to the door of the present invention, it is possible to adjust the building materials with the outer panel, and after mounting the skeleton on the body, the inner panel and the outer panel can be assembled, or the skeleton can be adjusted. Mount the inch panel assembled on the body, or mount the inner panel and outer panel assembled on the skeleton on the body, or mount the inner panel on the body and then assemble the skeleton and outer panel. The processes in the door assembly and door mounting lines can be made more flexible.

On the other hand, according to the door assembly method of the present invention, the inner panel,
Since the door interior parts are attached to the skeleton before the outer panel is assembled, it is possible to assemble the door interior parts without worrying about the presence of the inch panel and the outer panel. The attachment shall be made easy to work with. Of course, since the outer panel is assembled while adjusting the building materials, there is no need to adjust the building materials while repeatedly opening and closing the door.
