Then, the corrugated tube expanded from the slit is put on the wire harness so that the slit edges at both circumferential ends of the corrugated tube expanded from above the wire harness sandwich the regulating plate,
A jig for restricting the slit position of the corrugated tube is provided, wherein after fixing both ends of the corrugated tube in the longitudinal direction to the wire harness by tape winding, the wire harness is taken out from the receiving groove together with the corrugated tube. . In other words, the slit position regulating jig of the present invention is provided integrally with a regulating plate for regulating the slit position of the corrugated tube at the wire receiving portion of the wiring jig of the wire harness which stands on the wiring plate of the wire harness. ing.

When the slit position regulating jig of the present invention is used, when the corrugated tube expanded from above the received wire harness is put on the receiving groove, at least one of the corrugated tubes in the longitudinal direction is provided. The restricting plate enters the gap between the slit edges at both ends in the circumferential direction at the portion, thereby restricting the slit position. Therefore, the slit position does not move during the operation of winding and fixing both ends of the corrugated tube with the tape, and the straight line of the slit can be held. In order to more reliably hold the straight line of the slit, it is preferable to receive and support a predetermined length portion for attaching the corrugated tube of the wire harness by using a plurality of jigs for regulating the slit position. The slit position regulating jig receives and supports at least portions of the predetermined length of the wire harness to which the corrugated tube is attached, at least slightly before the both ends where the tape is wound.

When using any of the above jigs,
After fixing both ends of the corrugated tube with tape,
