These claw pieces 43, 44 are When the lid 42 is closed, a circle is drawn. The interval between the claw pieces 43 and 44 is an integral multiple of the pitch of the corrugated tube C (distance between adjacent valleys) described later. Further, an insertion plate 45 is continuously provided in the fixed portion 41. An engaging claw 46 that engages with the engaging piece 29 of the main protector 2 protrudes from the tip of the insertion plate 45, and insertion pieces 47 protrude from the left and right sides of the insertion plate 45. . Further, as shown in FIG. 3B, the band groove 50 is formed in the insertion plate 45 horizontally.

  Since the three-dimensional routing protector 1 has the above-described configuration, the three-dimensional routing protector 1 is three-dimensionally routed according to the following procedure.

  First, as shown in FIG. 2, the sub protector 4 is attached to a predetermined position of the wire harness W via the corrugated tube C in order to secure the dimension of the wire harness W in the sub protector attaching step. That is, a short corrugated tube C is provided around the wire harness W, and the corrugated tube C is fixed to the wire harness W by taping. Here, the “short length” means a length that is longer than the fixed portion of the sub protector and does not hinder the work. Next, as shown in FIG. 2 (a), the lid 42 of the sub protector 4 is opened, and as shown in FIG. 2 (b), the corrugated tube C is placed on the fixing portion 41 of the sub protector 4, and then FIG. As shown in (c), the lid 42 of the sub protector 4 is closed. Then, the claw piece 43 of the fixing portion 41 and the claw piece 44 of the lid 42 hold the corrugated tube C. At this time, since the distance between the claw pieces 43 and 44 is an integral multiple of the pitch of the corrugated tube C, all the claw pieces 43 and 44 mesh with the valleys of the corrugated tube C. Therefore, the sub protector 4 is firmly fixed to a predetermined position of the wire harness W through the corrugated tube C. Thereby, it will be in the state where the dimension of wire harness W was secured.

  When the dimension of the wire harness W is secured in this way, as shown in FIG. 3, the process proceeds to the sub protector fixing step, the sub protector 4 is fixed to the main protector 2, and the wire harness W is pulled out right above.

  For this purpose, as shown in FIG. 3A, after the wire harness W is housed in the main body 21 of the main protector 2, the lids 23A, 23B, 23C, and 23D of the main protector 2 are closed.

  Next, as shown in FIG. 3B, the sub protector 4 is placed on the main protector 2. Next, as shown in FIG. 3C, the sub protector 4 is dropped into the main protector 2 to be fitted. At this time, since it can be fitted to the main protector 2 simply by dropping the sub protector 4, it is excellent in workability.

  Next, as shown in FIG. 3 (d), the sub protector 4 is fixed to the main protector 2. For this purpose, the auxiliary lid 31 of the main protector 2 is rotated in the sub protector 4 side, that is, in the direction of arrow N, and the locking pieces 33 and 33 are locked to the locking claws 34 and 34. Further, a band (not shown) is fastened and completely fixed to the band groove 35 of the main protector 2 and the band groove 50 of the sub protector 4. Then, the sub protector 4 is fixed to the main protector 2, and the wire harness W is bent at the bent portion 26 and pulled out from the outlet 22D.

  Here, the three-dimensional routing operation of the wire harness W is completed.

  If it does in this way, in the state where the dimension of wire harness W was secured, wire harness W can be bent at a predetermined angle (here 90 degrees) inside protector 1 for three-dimensional routing. As a result, it is possible to route the wire harness W three-dimensionally while managing the dimensions of the wire harness W.

  Further, the wire harness W is firmly fixed to the bent portion 26 of the main protector 2 via the auxiliary lid 31 and the sub protector 4 by the fastening force of the band. There is no possibility that the dimensions of the wire harness W may be shifted when the vehicle is routed. And since the horizontal rib 28 is formed in the bending part 26 of the main protector 2, the fixing force of the wire harness W becomes still stronger.

  Moreover, since the corrugated tube C which fixes the wire harness W and the sub protector 4 is short, positioning of the sub protector 4 with respect to the wire harness W is easy, and at the same time, the fixing force between the two is increased, and workability is further improved. Becomes better.

<Third Embodiment>
FIG. 5 is a perspective view showing a third embodiment of the protector for three-dimensional routing according to the present invention.

  In the above-described embodiment, the case where the sub protector 4 is dropped and fitted to the main protector 2 has been described. However, as shown in FIG. 5, the sub protector 4 is slid from the side and fitted to the main protector 2. It doesn't matter. That is, a pair of left and right engaging claws 36, 36 are formed on the main body 21 of the main protector 2, and a pair of left and right engaging pieces 51, 51 are formed on the sub protector 4, and the sub protector 4 is attached to the main protector 2. When fitting, the sub protector 4 is slid from the side in the direction of arrow L with respect to the main protector 2, and the engaging claws 36 are inserted into the engaging pieces 51. In this case, the fixing force of the sub protector 4 with respect to the main protector 2 is strong because it is fitted in two places.
