The structure of the branch protector 10 according to the present embodiment is as described above. Next, a usage mode of the branch protector 10 will be described.
In the branch protector 10, each first branch arm portion 12 </ b> A is bent while each proximal side hinge portion 14 and each separated side hinge portion 23 are bent, or each first branch arm portion 12 </ b> A is kept linear. Thus, the pulling angle of the wire harness 90 can be changed.

  For example, in the first usage mode shown in FIG. 5, each of the close-side hinge portions 14 and the separate-side hinge portions 23 is maintained in the initial state, and each of the first branch arm portions 12A is substantially straight along the X-axis direction. Has been placed. For this reason, 90 A of 1st extraction parts of the wire harness 90 are pulled out to the X-axis direction in the state supported by each 1st branch arm part 12A. Further, the second lead-out portion 90B of the wire harness 90 is pulled out in the Y-axis direction while being housed in the housing space 19 of each second branch arm portion 12B. In this case, the movement in the width direction of the second lead portion 90 </ b> B of the wire harness 90 is restricted by each side plate 18. In addition, each wire harness 90 is fixed to the branch arm 12 by winding the tape 80 or the like. Thus, in the first usage mode, the wire harness 90 is branched in a cross shape.

  Further, for example, in the second usage mode shown in FIG. 6, the proximal side hinge portion 14 of one of the first branch arm portions 12A is bent, and the one first branch arm portion is bent. 12A is rotated about 90 degrees with the near-side hinge portion 14 as a fulcrum and is erected in the Z-axis direction. For this reason, one side of the first lead portion 90A of the wire harness 90 is drawn in the Z-axis direction while being supported by the one first branch arm portion 12A.

Thus, in the second usage mode, the wire harness 90 is branched three-dimensionally.

  Further, for example, in the third usage mode shown in FIG. 7, the proximity-side hinge portion 14 and the separation-side hinge portion 23 of one of the first branch arm portions 12A are bent in the same direction. The one first branch arm portion 12A is folded back and disposed substantially opposite to the other side of the other first branch arm portion 12A. For this reason, the first lead portion 90A of the wire harness 90 is pulled out in the X-axis direction while being supported by the other first branch arm portion 12A while being pressed against the first branch arm portion 12A from the upper side. Then, in this state, each first branch arm 12A is wound with 80 tapes to be put together. Further, the second lead-out portion 90B of the wire harness 90 is pulled out in the Y-axis direction while being housed in the housing space 19 of each second branch arm portion 12B. Thus, in the third usage mode, the wire harness 90 is branched into a T shape.

  As described above, according to the present embodiment, since the pull-out angle of the wire harness 90 can be changed by each close-side hinge portion 14 and each separate-side hinge portion 23, a plurality of pull-out angles of the wire harness 90 are different. This branch protector 10 can be applied to this wiring structure. Therefore, the branch protector 10 excellent in versatility is provided.

  Moreover, the freedom degree at the time of prescribing | regulating the drawer angle of the wire harness 90 is raised more by using combining the near side hinge part 14 and the separation | spacing side hinge part 23 suitably.

  Moreover, since the groove | channel 15 is provided only in the single side | surface of 12 A of 1st branch arms in the near side hinge part 14, this part does not become exceptionally thin. Therefore, when the first branch arm portion 12A is bent via the proximity-side hinge portion 14, the first branch arm portion 12A is prevented from being broken at the proximity-side hinge portion 14. On the other hand, since the groove 16 is provided on both surfaces of the first branch arm portion 12A in the separation-side hinge portion 23 that requires a relatively small stress during bending, the first branch is provided via the separation-side hinge portion 23. The arm portion 12A is flexibly bent.

  Moreover, since the several branch arm part 12 is arrange | positioned facing on both sides of the branch center part 11, it becomes possible to let the wire harness 90 follow a linear form to this each branch arm part 12 which opposes.

  Furthermore, since the fixing part 60 is provided in the branch center part 11, the wire harness 90 can be branched in the state fixed to the attachment object. Furthermore, since the second branch arm portion 12B includes the support plate 12D and the side plate 18, and the accommodation space 19 of the wire harness 90 is defined between the support plate 12D and the side plate 18, the second branch arm portion. It is possible to prevent the second lead portion 90B of the wire harness 90 from falling within 12B.
