FIG. 20 is a plan view showing a second example of a conventional binding sheet.

  When manufacturing this kind of wire harness, after wiring of all the wires that make up the wire harness was completed, key points such as terminal parts and branch parts where connectors were attached were bound with adhesive tape. . For example, as shown in FIG. 16, in order to bind the T-shaped branch part 2 where the branch line 1b branches from the trunk line 1a of the wire harness 1, as shown in FIG. 17, one side of the trunk line 1a, that is, the first The adhesive tape 3 is started to be wound from the first trunk portion 1c, and the adhesive tape 3 is wound in a cross shape at the branch portion 2 a plurality of times. Next, the adhesive tape 3 is wound a plurality of times in the vicinity of the branch portion 2 on the branch line 1b side, and the adhesive tape 3 is finished winding on the other side of the trunk line 1a, that is, the second trunk part 1d. Furthermore, the adhesive tape 3 is wound around the bundle of the electric wires 4 for the portions other than the branch portion 2 and bound.

  However, in this case, since the taping process is complicated, not only is the bundling operation of the branch portion 2 complicated, but also the amount of the adhesive tape 3 used is increased, which obstructs the weight reduction and diameter reduction of the wire harness 1. There was a drawback of becoming a factor.

Therefore, in order to compensate for these disadvantages, a technique (hereinafter referred to as “known technique 1”) for binding using a binding sheet having a shape corresponding to the branched shape (T-shaped, cross-shaped, etc.) of the wire harness 1 has been proposed. (For example, refer to Patent Document 1). That is, in this known technique 1, when binding the T-shaped branch portion 2, as shown in FIG. 18, a trident binding sheet 5 corresponding to the T-shape of the branch portion 2 is prepared, As shown in FIG. 19, this binding sheet 5 is directed to the branch portion 2, and after the three binding pieces 5 a of the binding sheet 5 are folded back, the leading ends of these binding pieces 5 a are fixed with an adhesive tape. . Further, when the cross-shaped branch portion 2 is bound, as shown in FIG. 20, a cross-shaped binding sheet 5 corresponding to the cross-shaped shape of the branch portion 2 is prepared, and the binding sheet 5 is connected to the branch portion. 2, the four binding pieces 5 a of the binding sheet 5 are folded back, and then the tips of the binding pieces 5 a are fixed with an adhesive tape.
