[0002]

2. Description of the Related Art In recent automobiles, the instrument panel is provided with electrical components such as meters, various switches, connection boxes, sensors, radios, and air conditioners. Electrical components such as a power window motor, an electric door mirror motor, and a door lock switch are arranged, and a wire harness formed by binding a number of electric wires for connecting these electrical components with tape or the like is arranged. Conventionally, as shown in Japanese Utility Model Application Laid-Open No. 6-51014, a number of clips are attached to a wire harness, and these clips are used to narrow the back of the instrument panel, the inside of the door panel, or the gap between the panel and the trim. Fixed along the routing path of the space.

[0003] In addition, the wire harness is liable to be damaged by coming into contact with other adjacent parts due to the vibration of the vehicle or the like. In order to prevent the damage, conventionally, a wire harness such as a corrugated tube or a resin protector is used. The current situation is that the protective parts are attached to the wire harness.

[0004] The wire harness does not have a fixed shape because it is simply a bundle of electric wires bound together with a tape or the like, and therefore, its shape changes due to its own weight. For this reason, the wiring harness is difficult to handle when it is mounted on a vehicle, and as a result, a great deal of labor and time are required for assembling the wire harness to the vehicle body.

[0005] Further, in the conventional wire harness, a clip is used as a fixture for attachment to a vehicle body panel or the like.
In addition, the use of tube protectors to protect from interference and contact with other parts has increased the number of parts due to these parts, which not only causes an increase in cost and work load, but also There was a problem that the harness itself became a factor that would be unnecessarily enlarged. Further, when a protection component is attached to the wire harness, there is a problem that abnormal noise is easily generated due to collision of the protection component with other components due to vibration or the like.

[0006]

SUMMARY OF THE INVENTION The present invention provides a wire harness mounting method which can reduce the work of assembling the wire harness to a vehicle while ensuring the support of the wire harness without increasing the number of parts. It is an object to provide a structure.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A wire harness mounting structure according to the present invention is a wiring harness mounting structure for forming a wiring groove having a concave cross section and wiring a wire harness in the wiring groove. A holding member is provided between the wiring groove and the wire harness, in which a plurality of protrusions having different heights is arranged at a constant arrangement cycle for each protrusion group having the same height. That is, in the present invention, in a long component such as an air duct or a reinforcement, a wiring groove having a concave cross section is formed, and between the wiring groove and the wire harness,
By interposing a holding member with a unique structure as described above,
Wire harness mounting structure. In the present invention,
The holding member may be a member separate from the component having the wiring groove, or may be formed integrally with the component.
When the holding member is a member separate from the component having the wiring groove, for example, a plurality of projections having different heights are arranged on the sheet-like body at a constant arrangement cycle for each projection group having the same height. It can be made to be. The shape of the projection is a mountain shape with a sharp apex angle, a mountain shape with a gentle apex angle, a mountain shape with a two-stage structure, and a mountain shape that is continuous in one direction (parallel or perpendicular to the groove direction of the routing groove). And the like. The arrangement of the projections may be any as long as they are arranged at a constant arrangement cycle for each projection group of the same height, for example, those in which a high height projection group and a low height projection group are alternately arranged, a projection And the like, which are arranged so that the height changes continuously. The protrusion is preferably formed of an elastic material, and examples of such an elastic material include elastomer, rubber, and the like. When the projection is formed of a material having low elasticity such as polyethylene or polypropylene, it is effective to provide the projection with a hollow structure to impart elasticity. In the case of a projection made of an elastic material, the filling rate of the material occupying the space when compressed and deformed is uniform at each of the projections having different heights by keeping the volume of the projection constant. Therefore, the elastic reaction force received by the wire harness is also adjusted relatively uniformly in the longitudinal direction.

[0009] According to the above-described configuration, the tall projection stably supports the wire harness in the wiring of the thin wire harness. Also, when laying a thick wire harness, short protrusions support the wire harness, but at this time, the tall protrusions are sufficiently compressed to the short protrusion level, so the supporting area and supporting force for the wire harness are large. It can be stably supported in response to the weight of a thick wire harness. Therefore, it is possible to stably support wire harnesses having different outer diameters in the wiring groove with the spacer having the same structure.
