It is conceivable to prevent erroneous assembling and improve workability.
[0005]
However, by using the identification tapes 3 of different colors in the manufacturing process of the wire harness 1, the types of the tapes 2 and 3 increase, and after the wires are wound around the tape 2 and bound, the identification tapes are further increased. Since it is necessary to additionally perform the tape winding operation of No. 3, there is a problem that the workability is reduced and the cost is increased.
[0006]
The present invention has been made in view of the above-described problems, and has as its object to provide a wire harness that facilitates arranging a vehicle body without increasing the cost even when there is no positioning clamp or the like.
[0007]

[0008]
With the above configuration, even when laying a wire harness without a clamp or the like on the vehicle body, the above-described reference position can be easily visually recognized as a mark by performing the above-described tape winding, and the wire harness to the vehicle body can be easily recognized. Since the alignment is simplified, the workability of arranging the wiring harness is improved.
In addition, since the reference position can be identified by devising the manner of winding the tape as described above, only one type of tape for binding the wire bundle is used, and an increase in the number of components is suppressed, and the tape The winding operation is also performed in only one step, so that it is possible to prevent a decrease in workability in manufacturing the wire harness, and it is possible to reduce the cost.
[0009]
As a specific means for changing the manner of winding the tape at the reference position of the wire bundle, the tape winding at the reference position may be half-wrapped and the other part may be roughly wound, or the tape winding at the reference position And the other part is preferably half-wrapped.
[0010]
The inner panel and the outer panel of the automobile are resin-molded, and a space surrounded by the inner panel and the outer panel is defined as a routing space for the wire harness, and a wire harness fixing portion is fixed to one of the inner panel and the outer panel. Or / and / or reinforcing ribs are provided integrally,
The wiring harness fixing portion and / or the reinforcing rib is used as a positioning portion, and the positioning is performed in a state where the reference position matches the positioning portion.
[0011]
