DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a perspective view of an embodiment in which, for example, a door 21 of an automobile is opened, FIG. 2 is a horizontal sectional view showing the door 21 closed, and the door 21 is attached to a body 23 via a hinge 22. A weather strip 24 for waterproofing between the door 21 and the body 23 is attached to 21. Door 21 is outer panel 2
5, an inner panel 26 and a door trim 27. A window glass (not shown) and a drive motor for the window glass (not shown) are installed between the outer panel 25 and the inner panel 26. The speaker 28 and the power window switch 2 are mounted on the door trim 27.
9 and the like are provided.

[0007] A flexible flat cable 30 is connected to electrical components such as the drive motor, the speaker 28 and the power window switch 29. The flat cable 30 has a structure in which a plurality of flat conductors are protected on both sides by an insulating sheet, and the insulating sheet is cut out in a strip shape. The rear portion of the flat cable 30 is disposed between the inner panel 26 and the door trim 27, and is fixed to the inner panel 26 by screws 31, for example.

The front portion of the flat cable 30 is led out from a cutout window 27 a formed in the door trim 27, passes through the room 32 of the weather strip 24, and passes through the body 23.
Side, for example, in the front pillar 33. The lower trim 34 is attached to the room 32 side of the pillar 33, and the flat cable 30 is connected to the lower trim 3.
4 is introduced into the pillar 33 through a cutout window 34a.

In the pillar 33, the flat cable 30 is introduced with a curved margin, and a front end thereof is connected with a connector 30a.
0a is connected to the connector 35a of the main harness 35. The flat cable 30 has a braided tube 36
Is mounted between the fixing screw 31 and the connector 30a. A flat cable 30 is provided on the inner surface of the pillar 33.
Cushioning member 37 for preventing generation of abnormal noise due to collision of
Is attached. The notch window 27a of the door trim 27 and the notch window 34a of the lower trim 34
A protector 38 such as a ring protector and a protector 39 for protecting the flat cable 30 are provided.

Here, a guide plate 40 for guiding the flat cable 30 in the pillar 33 in the front-rear direction is provided near the notch window 34a in the pillar 33. In addition, a flat cable 3 is provided in front of the guide plate 40.
A pair of coil springs 41 and 42 are provided so as to be opposed to each other while being bent along the wall while bending the margin of zero in the pillar 33. The coil springs 41 and 42 include arms 41a and 42a, respectively. When the door 21 is closed, the arms 41a and 42a deform the flat cable 30 outward, for example.
The main harness 35 is supported by the pillar 33 via the attachment 43, and the connectors 30a and 35a can swing to the positions shown by solid lines.

With this configuration, when the door 21 is opened as shown in FIG.
Following the movement of No. 1, it is pulled out from inside the pillar 33. At this time, the arms 41a, 42a of the coil springs 41, 42
Is moved inward by the flat cable 30, and the coil springs 41 and 42 are wound up. Also, connector 3
Oa and 35a oscillate toward the flat cable 30 to reduce the stress applied to the flat cable 30.

On the other hand, when the door 21 is closed,
Pushes the rear part of the flat cable 30 forward,
The coil springs 41, 42 are restored and the arms 41a, 42a
Moves outward and is drawn into the pillar 33 along the wall while bending the front part of the flat cable 30,
At the same time, the connectors 30a and 35a return to their original positions.

As described above, in the embodiment, when the door 21 is closed, the surplus portion of the flat cable 30 is provided by the coil spring 41,
Since it can be pulled into the pillar 33 by 42,
It is not necessary to install the flat cable 30 in the vertical direction, and it is not necessary to form a spiral portion in the flat cable 30. Therefore, it is possible to reduce the displacement of the installation space with respect to the flat cable 30 and the waste of the length of the flat cable 30. In addition, since the work of incorporating the coil springs 41 and 42 into the pillar 33 can be performed with the lower panel 34 removed,
Installation workability can be improved.

In the embodiment, since the braided tube 36 is attached to the flat cable 30, the flat cable 3
It is possible to improve the life and aesthetic appearance of 0. In addition, since the buffer member 37 is provided on the inner surface of the pillar 33, it is possible to prevent the generation of abnormal noise due to the abutment of the flat cable 30.

Further, since the flat cable 30 is disposed inside the weather strip 24, a waterproof structure can be eliminated, and a work for forming a through hole of the flat cable, which is conventionally required, is required. In addition, the work of attaching the grommet to the flat cable, the work of designing the grommet, and the like can be omitted, and the number of parts and the manufacturing cost can be reduced.

Although the flat cable 30 is fixed to the inner panel 26 of the door 21 in the embodiment, it may be fixed to a water proof (not shown). Further, although the front part of the flat cable 30 is curved in the pillar 33, the rear part of the flat cable 30 may be curved in the door 21. Further, although the flat cable 30 is bent, the flat cable 30 may be bent.
It can also be deformed into an arbitrary shape according to the zero habit.

[0017]

As described above, according to the cable arranging structure of the door opening / closing section according to the present invention, the flat cable is deformed by the coil spring and drawn into the surplus accommodation chamber, so that the installation space can be reduced. Can be realized,
The assembly work process can be shortened.
