For example, in Japanese Patent Application Laid-Open No. 2007-267532 (Patent Document 1) related to the earlier application of the present applicant, a clip 1 shown in FIGS. 9A and 9B is shown as an example of this type of vehicle body locking tool. . The clip 1 has a jig hole 3 formed at a branching point p of a board 2 having a shape corresponding to a branching form of a wire harness (not shown), and is used for locking a vehicle body on the back side of the board 2. A holding frame 4 to which the clip main body 5 is detachably attached is projected.

  As shown in FIGS. 10 (A) and 10 (B), the clip 1 passes the central axis 7a of the wiring jig 7 fixed to the work table 6 through the jig hole 3 so that the substrate 2 is placed on the work table. 6 is held horizontally and the wiring harness is branched on the substrate 2, and then each branch wire is wound around the substrate 2 with tape (not shown), and then the substrate 2 is removed from the wiring jig 7. The clip body 5 can be attached to the holding frame 4 and the clip body 5 can be attached to the wire harness so that the center thereof coincides with the branch point p.

  However, when the clip main body 5 is actually inserted into the clip mounting hole on the vehicle body panel side, the position of the clip mounting hole and the center position of the clip main body 5 may not exactly match. It is necessary to match the center of the clip body 5 with the position of the clip mounting hole by twisting or pulling, and the workability is poor, and there is a problem such as quality deterioration due to load applied to the wire harness.
