Both the electric wire 2 and the protective sheet 3 are fixed to this fixing portion 64. The band portion 50 is inserted into the head 51 while being wrapped around the electric wire 2, the protective sheet 3, and the bottom wall 61. By inserting the band portion 50 into the head 51, the electric wire 2 and the end portion 3e are fastened to the main body 6. The band member 5 fixes the electric wire 2 and the protective sheet 3 while aligning them along the bottom wall 61.
[0027] At the other fixing portion 64, the wires 2 are fixed to the bottom wall 61 by the band member 5. After the wires 2 and the protective sheet 3 are fixed to the two fixing portions 64, the cover 7 is assembled to the main body 6.
[0028] The protector 10 is configured by fixing both end portions 3e of the protective sheet 3 to the corresponding support members 4. The protector 10 includes the protective sheet 3, a pair of support members 4, and a plurality of band members 5. The protector 10 of this embodiment protects the electric wires 2 with the flexible protective sheet 3 and the support members 4 arranged on both ends of the protective sheet 3. The protective sheet 3 is flexible and can be easily deformed according to the wiring route. Furthermore, the length of the protective sheet 3 can be freely set according to the length of the wiring route. Therefore, the protector 10 of this embodiment is highly versatile and can be used with a variety of wiring routes.
[0029] As shown in FIG. 4 , a clip 67 is attached to the main body 6. The clip 67 is disposed on the bottom wall 61. The clip 67 protrudes in the depth direction Z of the wiring path 60 toward the side opposite to the electric wire 2. The clip 67 engages with a panel or the like of a vehicle to fix the support member 4 to the panel or the like. That is, in the protector 10 of this embodiment, the support members 4 at both ends can be fixed to the panel or the like by the clip 67. When the support members 4 at both ends are fixed to the panel or the like, the protective sheet 3 is disposed in the wiring path between the two support members 4. Because the protective sheet 3 is flexible, the work of fixing the support member 4 to the panel or the like is easy.
[0030] The protector 10 of this embodiment is configured so that some of the multiple electric wires 2 can be drawn out as branch wires from the support member 4. As shown in FIG. 7 , the branch wires are drawn out to the outside of the support member 4 through an opening 65. Multiple electric wires 2 are inserted into the support member 4 of FIG. 7 . Some of the multiple electric wires 2, electric wires 2a, are drawn out from the support member 4 along the extending direction X. Other electric wires 2b are drawn out to the outside from the opening 65 as branch wires.
[0031] The protective sheet 3 is wrapped around a plurality of electric wires 2 including electric wires 2a and 2b, and is fixed to the bottom wall 61 by a band member 5. Some of the electric wires 2a are fixed to the bottom wall 61 by the band member 5. Other electric wires 2b are branched from the bundle of electric wires between two fixing portions 64 and extend into the external space through an opening 65. In the protector 10 of this embodiment, the opening 65 is provided between the two fixing portions 64, so that the electric wires 2 can be fixed to the bottom wall 61 on both sides of the branching portion.
[0032] As described above, the protector 10 of this embodiment includes a flexible protective sheet 3, a support member 4, and a band member 5. The protective sheet 3 is wrapped around the electric wire 2. The support members 4 are disposed on both axial ends of the electric wire 2 on the protective sheet 3, respectively, to support the end 3e of the protective sheet 3 and the electric wire 2. The band member 5 fixes the end 3e of the protective sheet 3 and the electric wire 2 to the support member 4. The support member 4 has an opening 65 through which some electric wires 2b of the multiple electric wires 2 routed in the support member 4 can be pulled out as branch wires. The protector 10 of this embodiment is capable of branching some of the multiple electric wires 2 at the support member 4, and is therefore versatile and applicable to various routing configurations. Furthermore, the flexibility of the protective sheet 3 improves workability when packaging and transporting the wire harness 1. Furthermore, the container for transporting the wire harness 1 can be made smaller.
[0033] In the protector 10 of this embodiment, the support member 4 has a wiring path 60 including a bottom wall 61 and side walls 62 and 63. The side walls 62 and 63 are arranged on both sides of the bottom wall 61 in the width direction Y. The opening 65 is provided in the side wall 62. With this configuration, the electric wire 2 can be branched out from the opening 65 while being fixed to the bottom wall 61.
[0034] The support member 4 of this embodiment has a wiring path 60 in which the electric wire 2 is routed. The wiring path 60 is provided with two fixing portions 64 to which the electric wire 2 is fixed by the band member 5. The two fixing portions 64 are arranged at an interval along the extending direction X of the wiring path 60. The opening 65 is arranged between the two fixing portions 64. With this configuration, it is possible to fix the electric wire 2 to the support member 4 on both sides of the branch portion.
[0035] The two support members 4 arranged at both ends of the protective sheet 3 may have the same shape. In this case, it is possible to prevent an increase in the number of product numbers of the support members 4. Depending on the direction in which the branch wires are drawn, the support member 4 is arranged at the end 3e so that the opening 65 faces in the drawing direction.
[0036] A plurality of protectors 10 may be attached to one set of electric wires 2. In this case, a plurality of protective sheets 3 are wrapped around the electric wires 2 at different positions along the axial direction. Support members 4 are arranged at both ends of each protective sheet 3. Each support member 4 is fixed to the end 3e by a band member 5. When a plurality of protective sheets 3 are wrapped around the electric wires 2, the end portions 3e of two protective sheets 3 may be fixed to one support member 4. In this case, one protective sheet 3 is fixed to one fixing portion 64, and another protective sheet 3 is fixed to another fixing portion 64.
[0037] When the protective sheet 3 is long, a clip for adjusting the thickness may be attached to the central portion of the protective sheet 3 in the axial direction of the electric wires. The clip may, for example, flatten the shape of the bundle of electric wires. The clip may be a band clip that can be fixed to a panel or the like.
[0038] The support member 4 may have openings 65 on both sides in the width direction Y. In this case, one opening 65 is provided in one side wall 62, and another opening 65 is provided in the other side wall 63.
