Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door structure, and more particularly to a panel structure for a vehicle back door.

[0002]

2. Description of the Related Art In a conventional automobile back door 101,
As shown in FIG. 7, a door handle 105 is provided on the door outer panel 103, and a door latch 109 is provided under the door inner panel 107.
5 and the door latch 109 are connected by a latch rod 111.

Here, since the door inner panel 107 and the door outer panel 103 have little relative positional relationship with each other, the door handle mounting portion 113 for fastening the door handle 105 and the door latch for fastening the door latch 109. It was difficult to keep the distance n with the mounting portion 115 constant. Therefore, in order to keep the operation allowance h (see FIG. 9) of the door handle 105 constant, it was necessary to adjust the length m of the latch rod 111 each time in accordance with the interval n.

In order to eliminate the adjustment of the length m of the latch rod 111, as shown in FIG.
5 and the door latch 109 may be connected by a wire cable 117. However, if the length of the wire cable 117 is too short, the bending R of the wire cable 117 is reduced.
Since the dimension r of the portion 119 becomes small, the door handle 10
A large operating force f (see FIG. 9) was required when rotating the gear 5. On the other hand, if the length of the wire cable 117 is too long, the wire cable 117 may move inside the back door 101 and cause rattle noise while the vehicle is traveling, and when the door handle 105 is operated. Since the generated friction inside the wire cable 117 is large, the operating force f of the door handle 105 is large. Further, in the work of assembling the wire cable 117, in the outfitting and assembling process, the worker can
It is necessary to insert a hand into the inside of No. 1 and route the wire cable 117, which is a factor of increasing the number of work steps.
