  As mentioned above, although the wire harness wiring jig of this invention was demonstrated based on embodiment of illustration, this invention is not limited to this, The structure of each part is a thing of arbitrary structures which have the same function Can be replaced.

  For example, the binding band 22 according to the embodiment of the present invention may be a plate shape or a round shape as long as it is a flexible material so as to be adapted to the bundle shape of the wire harness (the plurality of electric wires 41).

  For example, in the above-described embodiment of the present invention, the case where the cylindrical member 14 is formed in a hollow substantially cylindrical shape has been described, but it may be formed in a hollow substantially polygonal column shape.

  In the above-described embodiment and other embodiments of the present invention, three or four partition walls 12 are formed in the branch center shaft portion 11, and three or four band insertion holes 28 are formed in the wire abutment ring 23. Although the case where it forms is demonstrated, if the partition wall 12 and the band insertion hole 28 are three or more (for example, five), it can change suitably.

  Further, in the above-described embodiment of the present invention and other embodiments, the case where one binding band 22 is partitioned by one partition wall 12 is illustrated and described, but a plurality of binding bands 22 are formed by one partition wall 12. (For example, two binding bands may be divided by one partition wall).

  The present invention is extremely useful for wiring the wire harness with one type of jig against the difference in diameter of the wire harness (difference in the number of wires).
