However, in the above harness support structure 41 according to the prior art, when the clips 47 (or the clips 57) are fixed to the harness 2, the fixing positions vary, so that these clips 47 (57) are used. When attached to the hole of the inner panel 8,
As shown in (a), the harness 2 is loosened between the clips. For this reason, the loose harness 2 (that is, the hard tube 42) interferes with the pillar trim 9, and the pillar trim 9 may rise.

If the rigid tube 42 cannot be used because the distance between the inner panel and the pillar trim is too narrow, the harness 2 may be damaged by contact with the edge of the body.

The use of a dedicated protector stabilizes the harness 2 and does not cause the above-mentioned problems. However, the dedicated protector itself is expensive, has no versatility, and must be manufactured in accordance with the shape of each vehicle model. Preparation costs such as molds are required. Also, as described above, the rigid tube 42 and the clip 4
7 (57) also has versatility,
In addition to the parts cost, the individual members (hard tube 42, clip 47 (57))
Must be fixed by the tape 48, which takes a lot of man-hours and costs, so that it is also expensive.

Accordingly, in view of the above prior art, the present invention can support a harness without causing slack, has good workability and is inexpensive, and can be easily provided in a narrow gap. It is an object to provide a harness support structure.

The distance between the clips 7 is adjusted so as to correspond to the distance between the two holes 8 a and 8 b provided in the inner panel 8 of the front pillar 3. Such an interval adjustment can be easily performed because the clip 7 can be moved little by little in the longitudinal direction of the protector 6 and the scale 6c of the protector 6 can be used as a mark.

Thereafter, the tape 4 is wound around the harness 2 and the protector 6. The reason why the tape 4 is wound around the protector 6 is to prevent the harness 2 from protruding from the opening of the holding portion 6a.

Finally, the clip 7 is mounted so that the mounting portion 7b of the clip 7 is fitted into the holes 8a and 8b of the inner panel 8. Thus, the present harness support structure 1 is provided on the front pillar 3.

Therefore, according to the harness support structure 1 having the above configuration, the following effects can be obtained.

(1) Since the clip 7 is attached not to the harness 2 but to the protector 6, the harness 2 is held by the holding portion 6a of the protector 6, and is straightened without loosening between the clips as in the related art. For this reason, problems such as poor fit along the pillar trim 9 and damage to the harness 2 due to the lifting of the pillar trim 9 can be eliminated.

(2) Since the clip interval can be adjusted by moving the clip 7 in small increments, the accuracy of the clip interval is high, and these clips 7 are securely and easily attached to the holes 8a and 8b of the front pillar 6. can do.
Therefore, workability is also improved. In addition, even when the harness is attached to the front pillar of another vehicle type or when the harness is attached to a portion other than the front pillar, the clip interval can be easily adjusted according to the situation of each attachment location. In particular, since the scale 6c provided on the holding portion 6a of the protector 6 can be used as a mark, it is very easy to adjust the clip interval.

(3) In addition to the front pillar 3, the protector 6 can be cut to a length suitable for the situation of each mounting location even when a harness is mounted on a front pillar of another vehicle type or a portion other than the front pillar. Can be used. In particular, since the scale 6c provided on the holding portion 6a can be used as a mark, it is easy to cut the protector 6 to a required length. Since the protector 6 can be cut to any length and used as described above and the clip interval can be set arbitrarily as described above, the harness support structure is very versatile.

(4) The clip 7 can be easily attached to the protector 6 without using a tape or the like. Therefore, the workability is good and the cost is low.

(5) The convex portions 7e and 7f provided on the engaging portion 7a of the clip 7 are fitted and locked in the concave portions of the engaging portion 6b of the protector 6, and are locked in one direction (right in FIG. 3 (b)).

7 can be selected as appropriate according to the situation of the mounting location on the body side.

Further, in the above-described embodiment, saw-toothed irregularities are provided on the engaging portion 6b of the protector 6, but the present invention is not limited to the saw-toothed shape, and irregularities of other shapes may be used. In addition, although it is desirable to provide the unevenness in this way, the present invention is not necessarily limited to this, and the unevenness may not be provided depending on the condition of the mounting portion on the body side.

[0045]

According to the present invention, the harness can be supported straight without drooping, as described above in detail with the embodiments of the present invention. Therefore, the harness may interfere with other structural members. There is no.

Further, the engagement position between the clip and the protector can be arbitrarily adjusted (adjustment of the clip interval and the like), and the clip can be securely and easily attached to the body. In particular, by providing a scale on the protector, it is easy to adjust the engagement position.

Further, the protector can be used after being cut into a required length according to the situation of the mounting portion on the body side. In particular, by providing a scale on the protector, such cutting becomes easy. In addition, since the protector can be used by being cut to an arbitrary length and the engagement position of the clip can be arbitrarily adjusted as described above, the versatility is very high.

Since the protector-side engaging portion of the protector has irregularities, the protector-side engaging portion and the clip-side engaging portion of the clip are securely engaged.
In particular, when the irregularities are saw-toothed, the engagement becomes more reliable.

By preparing various clips having different shapes of the mounting portions, the clips can be appropriately selected according to the situation of the mounting portion on the body side.

Further, by making the holder of the protector flat, it can be easily provided even in a narrow gap.
