SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a wire harness is provided on an inner surface of a hatchback door glass whose upper end is openably and closably attached to a vehicle body body via a hinge. Forming a concave harness insertion groove along the longitudinal direction in a weather strip attached to an inner surface near an outer peripheral edge of the hatchback door glass, and forming the wire harness in the harness insertion groove. Wherein the opening side of the harness insertion groove is positioned on the inner surface of the hatchback door glass, and a weather strip is attached to the inner surface of the glass. Provides routing structure.

[0008] According to the above configuration, the harness insertion groove is formed in the weather strip along the longitudinal direction, the wire harness is inserted into the insertion groove and integrated, and the wire harness is covered with the weather strip. It is possible to eliminate the need for a special exterior material such as a protector that has been required conventionally. In addition, the wiring of the wire harness to the hatchback door glass only needs to be inserted into the harness insertion groove of the weather strip, and the wire harness is also routed by attaching the weather strip to the hatchback door glass, and the dedicated wiring harness mounting Work can be eliminated. Furthermore, conventionally, since the weather strip and the wire harness exterior material were separately attached to glass,
Although the rear field of view was narrowed accordingly, the rear field of view can be widened by using only the weather strip.

[0009] A double-sided adhesive tape is attached to the surface of the weather strip to be attached to the hatchback door glass so as to close the opening of the harness insertion groove with the wire harness inserted, and the release paper of the double-sided adhesive tape is removed. It is preferable to peel it off and attach it to the inner surface of the hatchback door glass (claim 2). As described above, if the double-sided adhesive tape is attached to the weather strip before attaching to the hatchback door glass, the weatherstrip can be easily attached to the hatchback door glass simply by peeling off the release paper. Further, the wire harness can be securely held by the weather strip on the surface to be attached to the hatchback door glass.

Preferably, the adhesive or the adhesive applied to the double-sided adhesive tape is black. As described above, when the adhesive is black, the wire harness in the weather strip can be made invisible from the outside through the glass, and the appearance is improved.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show a first embodiment, and the same members as those of the conventional example are denoted by the same reference numerals. FIG. 1 shows a rear portion of a hatchback door glass type automobile. A hatchback door glass 11 (hereinafter abbreviated as glass) is directly opened and closed via a pair of left and right hinges 10, 10.
Mounted on A motor 5 of a rear wiper is attached to the left and right centers at the lower end of the glass 11, and a wire harness 12 for supplying power to the motor 5 is inserted through the grommet 13 from the center of the upper frame 8 a of the vehicle body. It is routed to the inner surface side, housed in a weather strip 14 attached along the vicinity of the outer peripheral edge of the inner surface of the glass 11, and routed to the motor 5.

The weatherstrip 14 is tightly sealed between the glass 11 and the vehicle body 8 in a closed state for waterproofing, and extends along a wiring route from rubber or elastomer, as shown in FIG. It has a cross-sectional shape.

More specifically, a recessed harness insertion groove 15 is formed along the longitudinal direction of the weather strip 14 so as to open to the glass sticking surface.
The wire harness 12 is inserted therein. The wire harness 12 is used to connect a plurality of electric wires w to a resin tube 1 made of an insulating resin.
As a form of the tubed harness inserted through 6,
It is inserted and arranged in the harness insertion groove 15. In addition,
A plurality of electric wires may be wound into a tape and inserted into the harness insertion groove 15 without being limited to the tubular harness form.

With the wire harness 12 inserted into the harness insertion groove 15, the harness insertion groove 1
5 is closed and the weather strip 1 is closed.
4, a double-sided adhesive tape 17 is fixed over the entire surface of the glass adhering surface 14a. Adhesive 1 for double-sided adhesive tape 17
7a is black, and when the release paper 17b on the front surface is peeled off and adhered to the inner surface of the glass 11, the entire adhered surface becomes black, so that the wire harness 12 in the harness insertion groove 15 is hidden from the outside of the glass 11. ing. In addition, since the opening of the harness insertion groove 15 is closed by the double-sided adhesive tape 17, the wire harness 12 is prevented from falling out of the harness insertion groove 15 before being attached to the glass 11.

As described above, in a state where the wire harness 12 is stored in the weather strip 14, the weather strip 14 is peeled off the release paper 17b along the inner surface of the glass 11 at the same position as the conventional weather strip. It is fixed by the adhesive 17a.

With the wiring harness wiring structure for the hatchback door glass having the above structure, when the work of attaching the weather strip 14 to the glass 11 is performed, the wiring harness is also wired at the same time. Can be eliminated. Further, since the wire harness 12 is continuously covered and protected by the weather strip 14, the appearance becomes better than before. Furthermore, since only the weather strip 14 is attached to the glass, the rear view can be widened.

FIG. 4 shows a second embodiment, in which a double-sided adhesive tape is not pasted to the weather strip 14 in advance.
With the wire harness 12 inserted into the harness insertion groove 15, the opening 15a of the harness insertion groove 15 is directly fixed to the inner surface of the glass using an adhesive 20. Also in this case, if the adhesive 20 is made black, it is not necessary to provide a blind smoke on the glass itself.

Further, the harness insertion groove 15 provided in the weather strip 14 may be made narrower on the opening side so as to be wider toward the back so that the wire harness 12 can hardly be seen from the outside just by being fitted.

[0020]

As is apparent from the above description, according to the present invention, a weather strip to be adhered along the inner peripheral surface of the hatchback door glass is used as the outer material of the wire harness and formed on the weather strip. Since the wire harness is integrated into the harness insertion groove, an exterior material such as a protector dedicated to the wire harness can be omitted, the number of components can be reduced, and the wiring work is also facilitated. In addition, integration with the weather strip eliminates a portion corresponding to the wiring of the conventional wire harness, so that there is an advantage that the rear view is widened and the vehicle is easy to drive.

Further, when the adhesive used for attaching the weather strip is black, the wire harness inserted into the harness insertion groove of the weather strip becomes invisible from the outside of the vehicle, so that the appearance is improved.
