[0001] The present invention relates to a wire harness. [Background technology]

[0002] A wiring member in which a cylindrical electromagnetic wave absorbing component is attached to a plurality of electric wires covered with a braided shield has been known, as disclosed in Patent Document 1. This wiring member has a position fixing member that fixes the relative positions of the electromagnetic wave absorbing component and the braided shield.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-198042 Summary of the Invention [Problem to be solved by the invention]

[0004] In the case of Patent Document 1, the position fixing member fixes the relative positions of the electromagnetic wave absorbing component and the braided shield by tightening the braided shield from the outside. Therefore, when the bracket is fixed to the vehicle body, a load or weight may be applied to the braided shield from the position fixing member. In this case, if a load or weight is applied to the braided shield from the position fixing member using the electromagnetic wave absorbing component as a seat, there is a possibility that the braided shield may be damaged.

[0005] An object of the present disclosure is to provide a wire harness that can make it difficult for the braid to be damaged at the electric wire portion where an electromagnetic wave absorbing member is attached. [Means for solving the problem]

[0006] A wire harness that solves the above problem includes an electric wire, a tubular first protective member that houses the electric wire, a tubular second protective member that is arranged coaxially with the first protective member to house the electric wire together with the first protective member, and an exterior member that is fixed at each end to an end of the first protective member and an end of the second protective member and houses the electric wire inside, wherein the electric wire has an electric wire main body, an electromagnetic wave absorbing member attached to the electric wire main body, and a braid that covers the outer periphery of the electric wire main body and the electromagnetic wave absorbing member, and the exterior member is fixed to the attachment point directly or indirectly via a fixing member in a state in which the electric wire portion to which the electromagnetic wave absorbing member is attached is movably housed. [Effects of the Invention]

[0007] The present disclosure can make it difficult for the braid to be damaged at the portion of the electric wire where the electromagnetic wave absorbing member is attached. [Brief explanation of the drawings]

[0009] First, embodiments of the present disclosure will be listed and described. [1] A wire harness according to the present disclosure includes an electric wire, a tubular first protective member that houses the electric wire, a tubular second protective member that is arranged coaxially with the first protective member to house the electric wire together with the first protective member, and an exterior member that is fixed at both ends to an end of the first protective member and an end of the second protective member and houses the electric wire inside, wherein the electric wire has an electric wire main body, an electromagnetic wave absorbing member attached to the electric wire main body, and a braid that covers the outer periphery of the electric wire main body and the electromagnetic wave absorbing member, and the exterior member is fixed to the attachment point directly or indirectly via a fixing member while movably housing the electric wire portion to which the electromagnetic wave absorbing member is attached.

[0010] According to the configuration of this example, the exterior member movably housing the electric wire portion to which the electromagnetic wave absorbing member is attached is fixed directly or indirectly to the attachment destination. Therefore, when the wire harness is fixed to the attachment destination, the braid located on the surface of the electromagnetic wave absorbing member is less likely to be subjected to an attachment load or stress. Therefore, the braid is less likely to be damaged at the electric wire portion to which the electromagnetic wave absorbing member is attached.

[0011] [2] In the above [1], the exterior member has an exterior member protrusion for directly fixing the wire harness to the attachment point. According to this configuration, a separate member for fixing the wire harness to the attachment point is not required, which contributes to simplifying the attachment structure of the wire harness.

[0012] [3] In the above [1], the exterior member has an exterior member protrusion for fixing to the fixing member, and the fixing member has a fixing member protrusion for fixing to the attachment destination and a recess for engaging the exterior member protrusion. With this configuration, it is possible to attach the wire harness to the attachment destination by using a conventional fixing member. Furthermore, there is no need to significantly change the shape or structure of the attachment destination to which the fixing member is fixed.

[0013] [4] In the above [3], the fixing member has the recess at a position near the end of a main body portion that supports the base end of the fixing member protrusion, and a fixing portion that fixes an end of the exterior member to one end of the first protective member and the second protective member is formed on the main body portion at a position opposite the recess. With this configuration, it is possible to fix the wire harness to the attachment point by using a so-called cantilever wire harness clamp. This contributes to simplifying the installation structure of the wire harness.

[0014] [5] In the above [1], the fixing member includes a first fixing member that fixes one end of the exterior member to an end of the first protective member, and a second fixing member that fixes the other end of the exterior member to an end of the second protective member. This configuration makes it possible to use a general-purpose wire harness clamp as the fixing member. This contributes to simplifying the mounting structure of the wire harness.

[0015] [6] In any one of the above [1] to [5], the electromagnetic wave absorbing member is formed in an annular shape, and the electric wire body is passed through a central hole. With this configuration, it is possible for the electromagnetic wave absorbing member to surround a predetermined portion of the electric wire body from the circumferential direction, making it possible to make it difficult for electromagnetic waves to leak.

[0016] [Details of the embodiments of the present disclosure] (First embodiment) A first embodiment of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In each drawing, for the convenience of explanation, some components may be exaggerated or simplified. Furthermore, the dimensional proportions of each part may differ from the actual ones.

[0017] (Wire harness 1) As shown in FIG. 1, a vehicle 2 includes a wire harness 1 as a type of electrical wiring of the vehicle 2. The wire harness 1 includes, for example, electric wires 5 that electrically connect a first electrical component 3 and a second electrical component 4 provided in the vehicle 2, and a cylindrical electric wire protection part 6 that houses the electric wires 5. The electric wire protection part 6 is routed, for example, such that a portion of the electric wire protection part 6 is exposed to the outside from the floor surface of the vehicle body. The wire harness 1 is formed, for example, in a path that is bent two-dimensionally or three-dimensionally.

[0018] (First protective member 9, second protective member 10) 2, the wire harness 1 includes a first protective member 9, a second protective member 10, and an exterior member 11. In this example, the first protective member 9, the second protective member 10, and the exterior member 11 configure the wire protection part 6.

[0019] The first protective member 9 is formed in a tubular shape, specifically a substantially cylindrical shape, to accommodate the electric wire 5 therein. The first protective member 9 is, for example, a corrugated tube. The first protective member 9 is formed, for example, so as to surround the outer periphery of the electric wire 5 over the entire circumferential direction. The first protective member 9 is formed in a bellows shape with convex and concave portions alternately arranged along the length direction (X-axis direction in FIG. 2). The material of the first protective member 9 may be, for example, a conductive resin material or a non-conductive resin material. The resin material may be, for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin.

[0020] The second protective member 10 is arranged coaxially with the first protective member 9 to accommodate the electric wire 5 together with the first protective member 9. In this example, the second protective member 10 is made of the same material as the first protective member 9, specifically, a corrugated tube. Therefore, the second protective member 10 is made of the same material as the first protective member 9, and therefore a description thereof will be omitted. The first protective member 9 and the second protective member 10 are arranged with a predetermined gap between them.

[0021] (Exterior member 11) The exterior member 11 has both ends fixed to the end of the first protective member 9 and the end of the second protective member 10, respectively, and houses the electric wires 5 therein. The exterior member 11 is provided so as to bridge between the end of the first protective member 9 and the end of the second protective member 10. The exterior member 11 is formed in a substantially cylindrical shape with both ends open. Specifically, the first protective member 9 is fitted into an opening 11a at one end of the exterior member 11, and the second protective member 10 is fitted into an opening 11b at the other end. The exterior member 11 is formed in a shape such that the center portion bulges outward in the radial direction by a predetermined amount compared to both ends.

[0022] For example, a relatively hard elastic material is used for the exterior member 11. The elastic material may be, for example, rubber such as ethylene propylene diene rubber or an elastomer. In this way, a resin material or a rubber material is used for the exterior member 11.

[0023] One end of the exterior member 11 is fixed to the first protective member 9 by a first fastener 12, and the other end is fixed to the second protective member 10 by a second fastener 13. The first fastener 12 and the second fastener 13 are, for example, resin or metal cable ties. Note that the first fastener 12 and the second fastener 13 may also be, for example, crimping rings or tape members.

[0024] The first fastener 12 and the second fastener 13 are attached by tightening the outer periphery of each end of the exterior member 11. Specifically, the first fastener 12 and the second fastener 13 are fixed in close contact with the outer periphery of the exterior member 11 in a liquid-tight manner. This prevents water and the like from entering through the gap between the first protective member 9 and the exterior member 11 and the gap between the second protective member 10 and the exterior member 11.

[0025] (wire 5) 3, the electric wire 5 includes an electric wire body 15, an electromagnetic wave absorbing member 16 attached to the electric wire body 15, and a braid 17 covering the outer periphery of the electric wire body 15 and the electromagnetic wave absorbing member 16. The electric wire 5 is housed inside a first protective member 9, a second protective member 10, and an exterior member 11. The electric wire 5 is, for example, a high-voltage electric wire to which a high voltage and a large current are applied.

[0026] The wire body 15 has a wire structure in which, for example, a core wire is covered with an insulating coating. The core wire may be, for example, a twisted wire, a columnar conductor, a tubular conductor, or a combination thereof. The core wire may be made of, for example, a metal material such as a copper or aluminum material. The insulating coating may be made of, for example, an insulating material such as a synthetic resin. The insulating coating may be made of, for example, a synthetic resin whose main component is a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene.

[0027] The number of electric wire bodies 15 may be, for example, one or more. The electric wire bodies 15 may be, for example, an electromagnetically shielded structure or a non-electromagnetically shielded structure.

[0028] (Electromagnetic wave absorbing material 16) As shown in FIG. 3 , the electromagnetic wave absorbing member 16 is disposed at a portion of the wire main body 15 that is housed in the exterior member 11. The outer surface of the electromagnetic wave absorbing member 16 is covered with a braid 17. The electromagnetic wave absorbing member 16 is formed in a tubular shape having a hole 18 through which the wire main body 15 is passed. The electromagnetic wave absorbing member 16 is formed, for example, in a substantially cylindrical shape. The electromagnetic wave absorbing member 16 is disposed at a distance from the first protective member 9 and the second protective member 10. The electromagnetic wave absorbing member 16 absorbs, for example, a portion of the electromagnetic waves radiated from the wire main body 15. The electromagnetic waves are, for example, electromagnetic noise.

[0029] The electromagnetic wave absorbing member 16 is, for example, a circular magnetic core. The magnetic core absorbs, for example, electromagnetic waves emitted from the electric wire main body 15 and converts them into mechanical energy such as vibration or thermal energy. This makes it less likely that the electromagnetic waves emitted from the electric wire main body 15 will affect peripheral devices, etc.

[0030] The magnetic core is, for example, a molded body containing a soft magnetic material. Examples of soft magnetic materials include iron (Fe), iron alloys, and ferrite. Examples of iron alloys include Fe-silicon (Si) alloys and Fe-nickel (Ni) alloys. Examples of magnetic cores that can be used include ferrite cores, amorphous cores, and permalloy cores. The ferrite core is, for example, made of soft ferrite that exhibits soft magnetism. Examples of soft ferrites include ferrites containing nickel (Ni) and zinc (Zn) and ferrites containing manganese (Mn) and zinc (Zn). The material of the magnetic core is appropriately selected depending on, for example, the frequency band of electromagnetic noise to be reduced.

[0031] (Braid 17) As shown in Fig. 3, the braid 17 is formed in a tubular shape so as to cover both the electric wire body 15 and the electromagnetic wave absorbing member 16. The braid 17 is formed, for example, so as to surround the electric wire body 15 over substantially the entire length in the longitudinal direction of the electric wire body 15 (the X-axis direction in Fig. 3). The braid 17 is formed, for example, so that the outer diameter of the portion covering the electromagnetic wave absorbing member 16 is larger than the outer diameter of the other portions. The electric wire body 15 to which the electromagnetic wave absorbing member 16 and the braid 17 are attached is housed in an internal space 19 formed by the first protective member 9, the second protective member 10, and the exterior member 11.

[0032] Examples of the braid 17 include a braided member made of a plurality of metal wires, and a braided member made of a combination of metal wires and resin wires. The metal wires are made of a copper-based or aluminum-based metal material, and the resin wires are made of a reinforced fiber with excellent insulation and shear resistance, such as para-aramid fiber.

[0033] (Structure for fixing the wire harness 1 to the mounting location 21) 2 and 3, the exterior member 11 movably houses the electric wire portion to which the electromagnetic wave absorbing member 16 is attached (hereinafter referred to as the absorbing portion 22). The absorbing portion 22 is formed to have a larger diameter than other portions of the electric wire 5 by the amount corresponding to the attached electromagnetic wave absorbing member 16. The absorbing portion 22 refers to the portion of the electric wire 5 that is composed of the electric wire main body 15, the electromagnetic wave absorbing member 16, and the braid 17.

[0034] The exterior member 11 is fixed directly or indirectly to the attachment point 21. In this example, the exterior member 11 is fixed directly to the attachment point 21. Specifically, the exterior member 11 has an exterior member protrusion 23 for directly fixing the exterior member 11 to the attachment point 21. The head of the exterior member protrusion 23 is formed, for example, with a substantially trapezoidal cross section. The exterior member protrusion 23 engages with a recess 24 formed in the attachment point 21. The recess 24 is, for example, a through hole. The attachment point 21 is, for example, a vehicle body.

[0035] (Operation of the embodiment) Next, the operation of this embodiment will be described. 3, the structure for fixing the wire harness 1 to the attachment point 21 is such that the exterior member 11, which movably houses the electric wires 5 at the portion where the electromagnetic wave absorbing member 16 is arranged, is fixed to the attachment point 21. In this way, in the case of this example, the absorbing portion 22, which is the portion of the electric wires 5 at which the electromagnetic wave absorbing member 16 is arranged, is not fixed to the exterior member 11 and is allowed to move inside the exterior member 11. Specifically, the absorbing portion 22 is arranged with a predetermined gap between it and the inner peripheral surface of the exterior member 11.

[0036] Incidentally, for example, in a structure in which the absorbing portion 22 is fastened with a bracket or the like to be fixed to the attachment destination 21, when the bracket is fixed to the attachment destination 21, the load generated during the fixing operation is applied to the braid 17 of the absorbing portion 22, which may damage the braid 17. On the other hand, in the present example, the absorbing portion 22 is not fixed in close contact with the exterior member 11. Therefore, during the fixing operation of fixing the wire harness 1 to the attachment destination 21, the load or stress generated in the exterior member 11 is unlikely to be applied to the braid 17 of the absorbing portion 22. Therefore, the braid 17 is unlikely to be damaged.

[0037] (Effects of the embodiment) According to the configuration of the above embodiment, the following effects can be obtained. (1-1) The wire harness 1 includes an electric wire 5, a cylindrical first protective member 9, a cylindrical second protective member 10, and an exterior member 11. The first protective member 9 houses the electric wire 5. The second protective member 10 is arranged coaxially with the first protective member 9 to house the electric wire 5 together with the first protective member 9. The exterior member 11 has both ends fixed to an end of the first protective member 9 and an end of the second protective member 10, respectively, and houses the electric wire 5 therein. The electric wire 5 has an electric wire main body 15, an electromagnetic wave absorbing member 16 attached to the electric wire main body 15, and a braid 17 covering the outer periphery of the electric wire main body 15 and the electromagnetic wave absorbing member 16. The exterior member 11 is fixed directly to an attachment destination 21 in a state in which the exterior member 11 movably houses a portion of the electric wire to which the electromagnetic wave absorbing member 16 is attached (in this example, an absorbing portion 22).

[0038] According to the configuration of this example, the exterior member 11, which movably houses the electric wire portion to which the electromagnetic wave absorbing member 16 is attached, is directly fixed to the attachment destination 21. Therefore, when the wire harness 1 is fixed to the attachment destination 21, the braid 17 located on the surface of the electromagnetic wave absorbing member 16 is less likely to be subjected to attachment load or stress. Therefore, the braid 17 can be made less likely to be damaged at the electric wire portion to which the electromagnetic wave absorbing member 16 is attached.

[0039] (1-2) The exterior member 11 has an exterior member protrusion 23 for directly fixing to the attachment destination 21. According to this configuration, a separate member for fixing the wire harness 1 to the attachment destination 21 is not required, which contributes to simplifying the attachment structure of the wire harness 1.

[0040] (1-3) The electromagnetic wave absorbing member 16 is formed in an annular shape, and the electric wire body 15 is passed through the central hole 18. According to this configuration, the electromagnetic wave absorbing member 16 can surround a predetermined portion of the electric wire body 15 from the circumferential direction, making it difficult for electromagnetic waves to leak.

[0041] (Second embodiment) Next, a second embodiment will be described. The second embodiment is an example in which the mounting structure of the wire harness 1 of the first embodiment is changed to a structure in which the wire harness 1 is indirectly fixed by a fixing member 30. Therefore, the same parts as those of the first embodiment are denoted by the same reference numerals and their description will be omitted, and only the different parts will be described in detail.

[0042] (Structure for fixing the wire harness 1 to the mounting location 21) 4, the exterior member 11 is indirectly fixed to the attachment 21 via a fixing member 30. Specifically, the exterior member 11 has an exterior member protrusion 31 for fixing to the fixing member 30. Note that the exterior member protrusion 31 may be the same as the exterior member protrusion 23 of the first embodiment, for example.

[0043] As shown in FIG. 5, the fixing member 30 has a fixing member protrusion 32 for fixing to the attachment destination 21, and a recess 33 for engaging the exterior member protrusion 31. The head of the fixing member protrusion 32 is formed, for example, with a generally trapezoidal cross section. The base end of the fixing member protrusion 32 is supported, for example, by a main body 34 of the fixing member 30. The main body 34 is formed, for example, in a plate shape, and the fixing member protrusion 32 is formed on the upper surface. The fixing member protrusion 32 is located, for example, near the center of the upper surface of the main body 34. The recess 33 is located, for example, near the end of the main body 34. The recess 33 is, for example, a through hole.

[0044] The fixing member 30 is formed with a fixing portion 35 that fixes the end of the exterior member 11 to the first protective member 9. The fixing portion 35 has, for example, a cable tie structure. The fixing portion 35 is disposed on the main body portion 34 at a position opposite the recess 33. In this way, the fixing member 30 may be an offset clamp that has the fixing portion 35 near the end of the main body portion 34.

[0045] 4, one end of the exterior member 11 is fixed to the first protective member 9 by a fixing portion 35 of the fixing member 30. The other end of the exterior member 11 is fixed to the second protective member 10 by, for example, a predetermined fixing device 36. In this example, the fixing device 36 is preferably, for example, a cable tie. In this manner, one of both ends of the exterior member 11 is fixed to the first protective member 9 by the fixing portion 35 of the fixing member 30, and the other is fixed to the second protective member 10 by the fixing device 36.

[0046] (Operation of the embodiment) 4, in this example, the exterior member 11 that movably houses the electric wires 5 at the portion where the electromagnetic wave absorbing member 16 is arranged is attached to the fixing member 30, and the fixing member 30 is fixed to the attachment destination 21. In this way, in this example as well, the absorbing portion 22 is not fixed to the exterior member 11 and is therefore allowed to move inside the exterior member 11. Therefore, when the wire harness 1 is attached to the attachment destination 21, the attachment load or weight is unlikely to be applied to the braid 17 of the absorbing portion 22. Therefore, the braid 17 is unlikely to be damaged.

[0047] Furthermore, the wire harness 1 is fixed to the attachment destination 21 by the fixing member 30, not by the exterior member 11. Therefore, it is possible to use a conventional member such as a wire harness clamp as the fixing member 30, and there is no need to significantly change the structure or shape of the attachment destination 21. Furthermore, since it is possible to use a wire harness clamp that has a proven track record, it is also possible to make the wire harness 1 less likely to fall off from the attachment destination 21.

[0048] (Effects of the embodiment) According to the configuration of the above embodiment, in addition to the effects described in the first embodiment, the following effects can be obtained.

[0049] (2-1) The exterior member 11 has an exterior member protrusion 31 for fixing to the fixing member 30. The fixing member 30 has a fixing member protrusion 32 for fixing to the attachment destination 21 and a recess 33 for engaging with the exterior member protrusion 31. In this way, the exterior member 11 is indirectly fixed to the attachment destination 21 via the fixing member 30 in a state in which the electric wire portion (in this example, the absorbing portion 22) to which the electromagnetic wave absorbing member 16 is attached is movably housed. According to this configuration, the wire harness 1 can be attached to the attachment destination 21 by using a conventional fixing member 30. Furthermore, there is no need to significantly change the shape or structure of the attachment destination 21 to which the fixing member 30 is fixed.

[0050] (2-2) The fixing member 30 has a recess 33 formed near the end of the main body 34 that supports the base end of the fixing member protrusion 32, and a fixing portion 35 that fixes the end of the exterior member 11 to the end of one of the first protective member 9 and the second protective member 10 (in this example, the first protective member 9) is formed on the main body 34 at a position opposite to the recess 33. According to this configuration, it is possible to fix the wire harness 1 to the attachment destination 21 by using a so-called cantilever wire harness clamp. This contributes to simplifying the attachment structure of the wire harness 1.

[0051] (Third embodiment) Next, a third embodiment will be described. Note that in the third embodiment, only the differences from the first and second embodiments will be described.

[0052] (Structure for fixing the wire harness 1 to the mounting location 21) 6, both ends of the exterior member 11 are fixed to the first protective member 9 and the second protective member 10 by fixing members 40, which are separate members from the exterior member 11. In this way, the fixing member 40 of this example includes a first fixing member 41 that fixes one end of the exterior member 11 to the end of the first protective member 9, and a second fixing member 42 that fixes the other end of the exterior member 11 to the end of the second protective member 10.

[0053] The first fixing member 41 and the second fixing member 42 are preferably, for example, wire harness clamps. In the case of a wire harness clamp, the first fixing member 41 has a band portion 41a that fixes one end of the exterior member 11 to the first protective member 9 and a protrusion 41b that is fixed to the attachment destination 21. In the case of a wire harness clamp, the second fixing member 42 has a band portion 42a that fixes the other end of the exterior member 11 to the second protective member 10 and a protrusion 42b that is fixed to the attachment destination 21.

[0054] (Operation of the embodiment) As shown in Fig. 6, in this example, one end of the exterior member 11 is fixed to the first protective member 9 by the first fixing member 41, and the other end of the exterior member 11 is fixed to the second protective member 10 by the second fixing member 42. Then, the first fixing member 41 and the second fixing member 42 are fixed to the attachment destination 21, thereby attaching the wire harness 1 to the attachment destination 21. In this way, also in this example, the absorbing section 22 is not fixed to the exterior member 11, and is therefore allowed to move inside the exterior member 11. Therefore, when the wire harness 1 is attached to the attachment destination 21, the attachment load or weight is unlikely to be applied to the braid 17 of the absorbing section 22. Therefore, the braid 17 is unlikely to be damaged.

[0055] Also in this example, since it is possible to use a conventionally used member such as a wire harness clamp as the fixing member 40, there is no need to significantly change the structure or shape of the attachment 21. Furthermore, since it is possible to use a wire harness clamp that has a proven track record, it is possible to make it difficult for the wire harness 1 to fall off from the attachment 21. Furthermore, it is also possible to use a general-purpose wire harness clamp having a protruding portion and a band portion as the fixing member 40.

[0056] (Effects of the embodiment) According to the configuration of the above embodiment, in addition to the effects described in the first and second embodiments, the following effects can be obtained.

[0057] (3-1) The fixing member 40 includes a first fixing member 41 that fixes one end of the exterior member 11 to an end of the first protective member 9, and a second fixing member 42 that fixes the other end of the exterior member 11 to an end of the second protective member 10. This configuration makes it possible to use a general-purpose wire harness clamp as the fixing member 40. This contributes to simplifying the mounting structure of the wire harness 1.

[0058] (Other embodiments) This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0059] In each embodiment, the electromagnetic wave absorbing member 16 is not limited to a ring-shaped member formed in the entire circumferential direction, but may be formed in a shape that is formed in part of the circumferential direction, for example. In each embodiment, the electromagnetic wave absorbing member 16 may have a structure in which a magnetic core is attached to a holder, for example.

[0060] In each embodiment, the exterior member 11 may be, for example, non-cylindrical. In the first and second embodiments, the exterior member protrusions 23, 31 may be provided in plural. In the second embodiment, a plurality of fixing member protrusions 32 may be provided.

[0061] In the second embodiment, the recesses 33 are not limited to holes, but may be grooves. In the second embodiment, the fixing member 30 is not limited to a cantilever wire harness clamp. In short, it may have any shape that can fix the exterior member 11 to the attachment 21 while holding the exterior member 11.

[0062] In the second embodiment, the exterior member 11 may be fixed to the fixing member 30 only by the exterior member protrusions 31. In the second embodiment, the fastener 36 is not limited to a cable tie, and other materials such as a resin tape may be used.

[0063] In the third embodiment, the first fixing member 41 and the second fixing member 42 are not limited to being the same member, but may be different members. In the third embodiment, the fixing member 40 is not limited to a wire harness clamp. The fixing member 40 may have any shape as long as it can fix the exterior member 11 to the first protective member 9 and the second protective member 10 and also to the attachment destination 21.
