Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method of assembling an automobile door.

(Prior Art and its Problems) Conventionally, automobile doors generally consist of a door body consisting of an inner panel and an outer panel, and door interior parts such as door lock parts assembled to the door body. In other words, in the conventional door body, the inner panel and outer panel are formed by joining three sides around the circumference, excluding the waist line, and therefore, it is difficult to assemble the door interior parts to the door body. Attachment is done using the many working holes provided in the inner panel.

More specifically, in the door mounting process (the process of attaching the door interior parts to the side of the door body) as shown in Japanese Patent Publication No. 60-59101, each door interior part is inserted through a working hole opened in the inner panel. They were to be assembled at predetermined positions on the inner surface of the door body.

By the way, among door interior parts, door lock parts and door lock mechanism parts such as key cylinders require connecting rods to connect the door lock parts and linking parts such as key cylinders. Therefore, conventionally, the key cylinder was assembled by inserting the key cylinder through the working hole in the inner panel and attaching it to the outer panel.
It was supposed to be connected to door lock parts, and the workability was extremely poor.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for assembling an automobile door, which improves the ease of assembling a key cylinder.

(Means and effects for solving the problem) The present invention improves the work efficiency when the key cylinder is inserted into the work hole opened in the inner panel for assembly as in the conventional case. Recognizing that there are limits, the door body is constructed from a skeleton, an inner panel and an outer panel that are assembled across the skeleton, and the key cylinder, which was conventionally attached to the outer panel, is now attached to the skeleton together with the door lock parts. After the key cylinder and door lock parts have been assembled in advance, the outer panel is assembled.

With such a configuration, it is possible to assemble the key cylinder without worrying about the inner panel or the like.

(Example) Embodiments of the present invention will be described below based on the drawings.

Overview of overall configuration In FIG. 1, 1 is the main body of an automobile side door (hereinafter referred to as the door main body).
