Description

The present invention relates to a wire protection material that protects electric wires, and a wire harness.

Conventionally, harness protection materials that protect wire harnesses have been proposed (see Patent Document 1). The harness protection material disclosed in Patent Document 1 has a flexible protection member provided on an adhesive layer of a fixing sheet that can be wrapped around the outer periphery of the wire harness. By bundling multiple electric wires and wrapping the fixing sheet around them, the wire harness is protected by the protection member.

JP 2010-74927 A

The above harness protection material is used by wrapping a fixing sheet around the wire harness. Because the wire harness is therefore rigid, it is difficult to position the wire harness along the wiring surface of the electrical wiring location.

The objective of this disclosure is to provide a wire protection material and a wire harness that can improve the ease of wiring.

The wire protection material that solves the above problem is configured to protect the outer surface of the wire that is routed in the wire routing location, and the protection material body that is interposed between the interference part present in the wire routing location and the wire is formed in a flat shape.

The wire harness that solves the above problem is configured to include an electric wire that is routed to an electric wire routing location, a fixing member that fixes the electric wire to the electric wire routing location, and an electric wire protection material that protects the outer surface of the electric wire, and the electric wire protection material has a protection material main body that is formed in a planar shape and is interposed between the electric wire and an interference part that exists at the electric wire routing location.

This disclosure makes it easier to route electrical wires.

First, the embodiments of the present disclosure will be listed and described.
[1] The wire protection material disclosed herein is configured to protect the outer peripheral surface of an electric wire arranged at an electric wire arrangement location, and a protective material main body interposed between an interference portion present at the electric wire arrangement location and the electric wire is formed in a planar shape.

According to this configuration, the protective material body of the wire protection material is planar, so that the wire protection material can be bent. This makes it possible to arrange the wire protection material along the shape of the wire installation location. Therefore, even when the wire protection material is configured to protect the outer circumferential surface of the wire, the wire does not have linear rigidity, and it is possible to arrange the wire together with the wire protection material along the shape of the wire installation location. This makes it possible to improve the ease of installation of the wire.

[2] The wire protection material has a tongue provided at least on one of the two longitudinal ends of the protection material body. The tongue is attached to the wire by a first fixation in which a fixing member for fixing the wire to the wire installation location is interposed between the wire and the tongue, a second fixation in which the fixing member is not interposed, or a combination of these. With this configuration, it is possible to assemble the wire protection material to the wire using an appropriate fixing method out of the first fixation, the second fixation, and a combination of these, depending on the shape of the wire installation location. This further contributes to improving the ease of installation of the wire.

[3] The first fixation is a structure in which the tongue is brought into contact with the fixing member attached and fixed to the electric wire. With this configuration, the electric wire is assembled integrally with the fixing member, and the electric wire protection material is fixed to this assembly, so that the first fixation structure can have multiple fixing points. This makes it possible to securely fix the electric wire, the electric wire protection material, and the fixing member. In addition, since the tongue is fixed based on the fixing member attached and fixed to the electric wire, it is possible to position the electric wire protection material relative to the electric wire.

[4] The first and second fixings are configured to assemble the tongue piece to the electric wire by wrapping a tape member around it. This configuration makes it possible to fix the electric wire protection material to the electric wire by a simple method using a tape member.

[5] The fixing member has an engagement portion that engages with the electric wire installation location and an arm portion extending from the engagement portion. The first fixation is a structure in which the arm portion is interposed between the electric wire and the tongue. With this configuration, it is possible to fix the tongue portion of the electric wire protection material by wrapping it around the arm portion of the fixing member. Therefore, it is possible to firmly attach the electric wire protection material to the electric wire.

[6] The tongue is formed in a shape that makes surface contact with the arm. With this configuration, the surface when the tongue is placed against the arm is flat, so the tongue is less likely to shift out of position. This makes it possible to prevent the wire protection material from shifting out of position after attachment to the wire routing location. In addition, it is possible to increase the contact area between the tongue of the wire protection material and the fixing member, so it is also possible to press the wire protection material firmly against the fixing member.

[7] The fixing member has an arm portion on only one side of the engagement portion. The electric wire, the tongue, and the arm portion are aligned so that their axes are aligned in the stacking direction. With this configuration, the electric wire, the tongue, and the arm portion can be stacked, making it possible to compactly organize this portion.

[8] The protective material body is flexible. With this configuration, when the wire protective material is placed at the electric wire installation location, it is less affected by the shape of the electric wire installation location. This is advantageous for placing the wire protective material at the electric wire installation location without gaps.

[9] The protective material body has a displacement-permitting portion that prevents the electric wire from protruding from the protective material body even if the electric wire moves in the planar direction of the protective material body. With this configuration, even if the electric wire is displaced in the planar direction of the protective material body when the electric wire is assembled or when the electric wire vibrates, the electric wire is less likely to protrude from the electric wire protective material. Therefore, it is possible to provide optimal protection for the electric wire.

[10] The wire harness of the present disclosure includes an electric wire arranged in an electric wire arrangement location, a fixing member that fixes the electric wire to the electric wire arrangement location, and an electric wire protection material that protects the outer surface of the electric wire, and the electric wire protection material has a protection material main body that is formed in a planar shape and is interposed between the electric wire and an interference portion that is present in the electric wire arrangement location.

According to this configuration, the same effects as those of the wire protective material can be obtained, and therefore it is possible to improve the ease of routing of the wires and therefore the wiring harness.
[11] At least a part of the outer circumferential surface of the electric wire, where the wire protective material is laid, is provided with a bend-allowing protective layer that can bend together with the electric wire while protecting the electric wire. With this configuration, even when the electric wire is bent, the outer circumferential surface of the electric wire can be suitably protected.

[12] At least a portion of the outer circumferential surface of the electric wire that is stepped on by the user is provided with a rigid hard protective layer. With this configuration, the portion of the outer circumferential surface of the electric wire that is frequently stepped on by the user is protected by the rigid hard protective layer, so that the electric wire can be protected even more effectively.

[13] The wire protection material has a tongue provided at least at one of the longitudinal ends of the protection material body. The tongue is attached to the wire by a first fixation in which a fixing member for fixing the wire to the wire installation location is interposed between the tongue and the wire, a second fixation in which the fixing member is not interposed, or a combination of these. With this configuration, the same effect as the wire protection material can be obtained.

[14] The fixing member has an engagement portion that engages with the electric wire installation location and an arm portion that extends from the engagement portion to only one side. The first fixation is a structure in which the arm portion is interposed between the electric wire and the tongue, and the wire protection material is fixed to the electric wire. With this configuration, it is possible to position the wire protection material relative to the electric wire by fixing the tongue of the wire protection material based on the arm portion of the fixing member.

[15] The fixing member includes a first fixing member involved in assembling the wire protection material to the wire, and a second fixing member not involved in assembling the wire protection material to the wire. The second fixing member has an engagement portion that engages with the wire installation location and a pair of arms extending on both sides from the engagement portion, and the pair of arms are directly fixed to the wire. With this configuration, the position of the second fixing member is not affected by the wire protection material. Therefore, there is a degree of freedom in the positioning of the second fixing member, making it possible to attach the second fixing member in an optimal position.

[Details of the embodiment of the present disclosure]
Specific examples of the wire protective material and wire harness 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 convenience of explanation, some of the configurations may be exaggerated or simplified. Furthermore, the dimensional ratios of each part may differ from the actual ones.

[Overview of installation of wire harness 1]
1, a wire harness 1 that electrically connects electrical components is arranged in an electric wire arrangement location 2. The wire harness 1 is, for example, an in-vehicle harness. In this case, the electric wire arrangement location 2 includes, for example, a floor surface 3 in the vehicle interior and a standing wall 4 that stands against the floor surface 3. In this way, the wire harness 1 is arranged in a location that is likely to be stepped on directly or indirectly by a user.

[General configuration of wire protective material 8]
1 , a wire protection material 8 that protects the outer peripheral surface of the wire 7 is interposed between the wire harness 1 and the wire arrangement location 2. The wire protection material 8 has a planar protection material main body 10 that is interposed between the wire 7 and an interference portion 9 present at the wire arrangement location 2. In this manner, the wire protection material 8 is a protection plate (protective sheet) that protects the outer peripheral surface of the wire 7. The interference portion 9 is, for example, a welding burr that occurs at the boundary between metal materials.

As shown in FIG. 2, the protective material body 10 is formed, for example, in a substantially rectangular shape. The protective material body 10 is flexible. The wire protection material 8 is capable of bending at least at the protective material body 10. The wire protection material 8 is preferably made of, for example, a resin, and PP (polypropylene) is used as one example. The wire protection material 8 is manufactured inexpensively, for example, by punching a sheet material out of PP.

The wire protection material 8 has a tongue 11 provided at at least one end (both ends in this example) of the protective material body 10 in the length direction (X-axis direction in FIG. 2). The tongue 11 is formed so as to protrude in the length direction from the center of the protective material body 10 in the width direction (Y-axis direction in FIG. 2). In this example, the tongue 11 includes a first tongue 11a arranged along the vertical wall 4 and a second tongue 11b arranged along the floor surface 3. The length La of the first tongue 11a is longer than the length Lb of the second tongue 11b (La>Lb). At the tip of the tongue 11, a hook portion 12 is formed that protrudes on both sides in the width direction (Y-axis direction in FIG. 2) of the wire protection material 8.

[General configuration of electric wire 7]
As shown in Fig. 3, the electric wire 7 includes a wire body 14 consisting of one or more electric wirings. A hard protective layer 15 that protects the electric wire 7 and has rigidity is provided on at least a part of the outer peripheral surface of the electric wire 7 (wire body 14) where the user steps on the outer peripheral surface. The hard protective layer 15 is, for example, a sheet material, and is wound around the electric wire body 14. The hard protective layer 15 is formed to a length that reaches the second tongue 11b of the wire protection material 8.

At least a portion of the outer peripheral surface of the electric wire 7 (electric wire body 14) where the electric wire protection material 8 is laid is provided with a bend-permitting protective layer 16 that can bend together with the electric wire 7 while protecting the electric wire 7. The bend-permitting protective layer 16 is, for example, a sheet material, and is wound around the electric wire body 14. In this example, the bend-permitting protective layer 16 is formed to be the same or approximately the same length as the protective material body 10.

It is preferable that the electric wire body 14 is wrapped with a tape 17 that has no protective function, and that the hard protective layer 15 and the bend-permitting protective layer 16 are provided on the outside. Therefore, the tape 17 is exposed to the outside in the places of the electric wire 7 (electric wire body 14) where the hard protective layer 15 and the bend-permitting protective layer 16 are not provided. It is not necessary that the tape 17 is provided on the entire surface of the electric wire body 14, and it may be omitted, for example, in the area of the bend-permitting protective layer 16.

[Outline of fixing the wire harness 1 to the electric wire arrangement location 2]
1, the wire harness 1 is attached and fixed to an electric wire routing location 2 by two fixing members 20. In this example, the wire harness 1 is fixed to the electric wire routing location 2 at two locations, a floor surface 3 and a standing wall 4. The fixing members 20 used for fixing to the standing wall 4 are referred to as a "first fixing member 20a," and the fixing member 20 used for fixing to the floor surface 3 is referred to as a "second fixing member 20b." The fixing members 20 are so-called clamps.

The first fixing member 20a has an engagement portion 21 that engages with the electric wire arrangement location 2, and an arm portion 22 that extends from the engagement portion 21 to only one side. The first fixing member 20a is what is called a "single-sleeve clamp." The second fixing member 20b has an engagement portion 23 that engages with the electric wire arrangement location 2, and a pair of arms 24 that extend from the engagement portion 23 to both sides. The second fixing member 20b is what is called a "double-sleeve clamp." In addition, in this example, the first fixing member 20a is involved in the assembly of the electric wire protection material 8 to the electric wire 7, but the second fixing member 20b is not involved.

[Outline of fixing the wire protective material 8 to the wire 7]
4 and 5, the tongue 11 is attached to the electric wire 7 by a first fixation in which a fixing member 20 for fixing the electric wire 7 to the electric wire installation location 2 is interposed between the tongue 11 and the electric wire 7, a second fixation in which the fixing member 20 is not interposed, or a combination of these. In this example, the first fixation is used for the first tongue 11a, and the second fixation is used for the second tongue 11b. That is, the first tongue 11a is fixed to the electric wire 7 with the first fixing member 20a sandwiched therebetween. On the other hand, the second tongue 11b is directly fixed to the electric wire 7 without the second fixing member 20b.

The first fixation is a structure in which the tongue 11 (first tongue 11a) is brought into contact with the fixing member 20 (first fixing member 20a) that is attached and fixed to the electric wire 7. Specifically, the electric wire 7 and the first fixing member 20a are first fixed by wrapping tape around them, and then the first tongue 11a of the electric wire protection material 8 is fixed to this assembly.

The first and second fixings are structures in which the tape member 26 (26a, 26b) is wound around the periphery to assemble the tongue to the electric wire. Specifically, the first fixing is, for example, a structure in which the electric wire 7 is placed on the arm 22 of the first fixing member 20a, and the electric wire 7 and the first tongue 11a are sandwiched between the arm 22 of the first fixing member 20a, and the tape member 26a is wound around the periphery to assemble them together. Therefore, the electric wire 7, the first tongue 11a, and the arm 22 are fixed together by wrapping the tape member 26a around the periphery with the arm 22 positioned between the electric wire 7 and the first tongue 11a. In this way, the first fixing is a structure in which the arm 22 is interposed between the electric wire 7 and the first tongue 11a to fix the electric wire protection material 8 to the electric wire 7. The second fixation is achieved, for example, by placing the electric wire 7 on the second tongue piece 11b and wrapping the wires around the second tongue piece 11b with tape member 26b, thereby assembling the wires together.

The protective material body 10 has a displacement allowance portion 27 that prevents the electric wire 7 from protruding from the protective material body 10 even if the electric wire 7 moves in the planar direction of the protective material body 10. In this example, the displacement allowance portion 27 is provided on both sides of the protective material body 10 in the width direction. The displacement allowance portion 27 is also a sheet portion that is integrated with the protective material body 10.

The second fixing member 20b has a pair of arms 24 that are directly fixed to the electric wire 7. In this example, the second fixing member 20b is fixed integrally to the electric wire 7 by wrapping each of the pair of arms 24 around the electric wire 7 with tape 28.

As shown in FIG. 6, the first tongue 11a is formed in a shape that makes surface contact with the arm 22 of the first fixing member 20a. This allows the first tongue 11a to be placed on the plane of the arm 22, rather than directly contacting the outer periphery (curved surface) of the electric wire 7. Furthermore, the electric wire 7, the first tongue 11a, and the arm 22 are aligned and arranged so that their axes P are aligned in the stacking direction (Z-axis direction in FIG. 6). In other words, if the axis P of the electric wire 7 is "P1", the axis P of the first tongue 11a is "P2", and the axis P of the arm 22 is P3, then the axes P1 to P3 are aligned in a straight line in the vertical direction.

[Action]
Next, the operation of the wire protective member 8 (wire harness 1) of this embodiment will be described.
7, in this example, since the wire protective material 8 is plate-shaped (flat), when the wire harness 1 is shipped, the wire harness 1 can be folded and packed at the portion of the wire protective material 8. Therefore, the wire harness 1 can be compactly stored in a roughly U-shape, which makes it easy to handle during transportation.

As shown in FIG. 8, when attaching the wire harness 1 to the electric wire routing location 2, the packaged wire harness 1 is removed and the fallen electric wires 7 are raised to make the wire harness 1 roughly L-shaped. Then, the engaging portion 21 of the first fixing member 20a is engaged with the engaged portion 30 (shown in FIG. 9) of the standing wall 4, and the engaging portion 23 of the second fixing member 20b is engaged with the engaged portion 31 (shown in FIG. 1) of the floor surface 3. In this example, the engaged portion 30 is, for example, a recess (hole). The engaged portion 31 is also a recess (hole) provided in the base 32 (shown in FIG. 1) of the floor surface 3.

As shown in FIG. 9, the wire protection material 8 is fixed to the first fixing member 20a by wrapping it around the tape member 26a. When the first fixing member 20a is fixed to the engaged portion 30, the wire protection material 8 can be pressed in the attachment direction of the first fixing member 20a (the direction of the arrow A in FIG. 9). In other words, the wire protection material 8 can be positioned along the wire routing location 2 with little gap.

As shown in FIG. 10, even if the wire harness 1 has excess length, the excess length can be absorbed by the bending angle of the wire protection material 8. In other words, if the wire harness 1 has excess length, the wire harness 1 can be pushed in by the excess length, and the wire protection material 8 bends to fit inward, making it possible to arrange the wire harness 1 along the wire routing location 2. Furthermore, the height H of the wire harness 1 is limited to the thickness of the wire main body 14, the surrounding protective layers (hard protective layer 15, bend-tolerant protective layer 16), and the wire protection material 8. Therefore, the height H of the wire harness 1 can be kept low.

As shown in FIG. 11, when the harness position is adjusted during assembly of the wire harness 1 or when vibrations occur in the vehicle, the electric wire 7 may sway left and right (in the directions of arrows B1 and B2 in the figure) along the planar direction of the electric wire protection material 8. In this example, because the displacement allowance portions 27 are provided on both sides of the protection material main body 10, it is possible to maintain the electric wire 7 resting on the electric wire protection material 8 even if the electric wire 7 sways left and right. This makes it possible to reduce the likelihood of a situation in which the electric wire 7 is damaged.

According to the wire protective material 8 (wire harness 1) of the above embodiment, the following effects can be obtained.
(1) The wire protection material 8 protects the outer peripheral surface of the electric wire 7 arranged in the electric wire arrangement location 2. The wire protection material 8 has a protection material main body 10 formed in a planar shape and interposed between an interference portion 9 present in the electric wire arrangement location 2 and the electric wire.

According to this configuration, the protective material body 10 of the electric wire protection material 8 is planar, so that the electric wire protection material 8 can be bent. This makes it possible to arrange the electric wire protection material 8 along the shape of the electric wire installation location 2. Therefore, even when the electric wire protection material 8 is configured to protect the outer circumferential surface of the electric wire 7, the electric wire 7 does not have linear rigidity, and it is possible to arrange the electric wire 7 together with the electric wire protection material 8 along the shape of the electric wire installation location 2. This improves the ease of installation of the electric wire 7.

(2) The wire protection material 8 has a tongue 11 provided on at least one of the longitudinal ends of the protection material body 10. The tongue 11 is attached to the wire 7 by a first fixation in which a fixing member 20 for fixing the wire 7 to the wire installation location 2 is interposed between the wire 7, a second fixation in which the fixing member 20 is not interposed, or a combination of these. With this configuration, it is possible to assemble the wire protection material 8 to the wire 7 using an appropriate and optimal fixing method out of the first fixation, second fixation, and combinations of these, depending on the shape of the wire installation location 2. This further contributes to improving the ease of installation of the wire 7.

(3) The first fixation is a structure in which the tongue 11 (in this example, the first tongue 11a) is brought into contact with the fixing member 20 (in this example, the first fixing member 20a) that is attached and fixed to the electric wire 7. With this configuration, the electric wire 7 is assembled integrally with the fixing member 20, and the electric wire protection material 8 is fixed to this assembly, so that the first fixation structure can have multiple fixing points. Therefore, the electric wire 7, the electric wire protection material 8, and the fixing member 20 can be firmly fixed. In addition, since the tongue 11 is fixed based on the fixing member 20 that is attached and fixed to the electric wire 7, the electric wire protection material 8 can be positioned relative to the electric wire 7.

(4) The first and second fixings are configured to assemble the tongue piece 11 to the electric wire by wrapping the tape member 26 around it. With this configuration, the electric wire protection material 8 can be fixed to the electric wire 7 by a simple method using the tape member 26.

(5) The fixing member 20 (first fixing member 20a in this example) has an engagement portion 21 that engages with the electric wire installation location 2 and an arm portion 22 extending from the engagement portion 21. The first fixation is a structure in which the arm portion 22 is interposed between the electric wire 7 and the tongue 11 (first tongue portion 11a in this example). With this configuration, it is possible to fix the first tongue portion 11a of the electric wire protection material 8 by wrapping it around the arm portion 22 of the first fixing member 20a. Therefore, the electric wire protection material 8 can be firmly attached to the electric wire 7.

(6) The tongue 11 (in this example, the first tongue 11a) is formed in a shape that makes surface contact with the arm portion 22. With this configuration, the surface when the first tongue 11a is placed against the arm portion 22 is flat, so the first tongue 11a is less likely to shift out of position. This makes it possible to make the wire protection material 8 less likely to shift out of position after attachment to the wire installation location 2. In addition, since it is possible to increase the contact area between the first tongue 11a of the wire protection material 8 and the first fixing member 20a, the wire protection material 8 can be firmly pressed against the first fixing member 20a.

(7) The fixing member 20 (in this example, the first fixing member 20a) has a shape that has an arm 22 on only one side of the engagement portion 21. The electric wire 7, tongue 11 (in this example, the first tongue 11a), and arm 22 are aligned so that axes P1 to P3 are aligned in the stacking direction. With this configuration, it is possible to stack the electric wire 7, first tongue 11a, and arm 22, so this part can be compactly organized.

(8) The protective material body 10 is flexible. With this configuration, when the wire protection material 8 is placed at the electric wire installation location 2, it is less affected by the shape of the electric wire installation location 2. This is advantageous for placing the wire protection material 8 at the electric wire installation location 2 without any gaps.

(9) The protective material body 10 has a displacement allowance portion 27 that prevents the electric wire 7 from protruding from the protective material body 10 even if the electric wire 7 moves in the planar direction of the protective material body 10. With this configuration, even if the electric wire 7 is displaced in the planar direction (left-right direction) of the protective material body 10 when the electric wire 7 is assembled or when the electric wire 7 vibrates, the electric wire 7 is less likely to protrude from the wire protection material 8. Therefore, the electric wire 7 can be protected in an optimal manner.

(10) At least a portion of the outer circumferential surface of the electric wire 7 where the electric wire protection material 8 is laid is provided with a bend-tolerant protective layer 16 that can bend together with the electric wire 7 while protecting the electric wire 7. With this configuration, the outer circumferential surface of the electric wire 7 can be suitably protected even when the electric wire 7 is bent and positioned.

(11) At least a portion of the outer surface of the electric wire 7 that is stepped on by the user is provided with a rigid hard protective layer 15. With this configuration, the portion of the outer surface of the electric wire 7 that is frequently stepped on by the user is protected by the rigid hard protective layer 15, so that the electric wire 7 can be protected even more effectively.

(12) The fixing member 20 includes a first fixing member 20a that is involved in assembling the wire protection material 8 to the wire 7, and a second fixing member 20b that is not involved in assembling the wire protection material 8 to the wire 7. The second fixing member 20b has an engagement portion 23 that is engaged with the wire installation location 2, and a pair of arms 24 that extend on both sides from the engagement portion 23, and the pair of arms 24 are fixed directly to the wire 7. With this configuration, the position of the second fixing member 20b is not affected by the wire protection material 8. Therefore, the second fixing member 20b can be positioned freely, and the second fixing member 20b can be attached in an optimal position.

This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.
The wire protection material 8 is not limited to being fixed to the wires 7 by the method using the tape member 26. For example, a fixing method using an adhesive or a fastener may be used.

The shape of the protective material body 10 is not limited to a substantially rectangular shape, and may be changed to, for example, a triangular shape, a trapezoidal shape, a round shape, or the like.
The present invention is not limited to a method in which the electric wire 7 and the fixing member 20 are first fixed, and then the wire protection member 8 is fixed to this assembly. For example, a method in which the electric wire 7, the wire protection member 8, and the fixing member 20 are fixed at the same time may be used.

The electric wire 7, the electric wire protection material 8, and the fixing member 20 are not limited to a structure in which the fixing member 20 is disposed between the electric wire 7 and the electric wire protection material 8.

The location where the fixing member 20 is fixed is not limited to a wall or a seat, and may be any location where the fixing member 20 can be fixed.
The tongue piece 11 may be provided on only one side, and the other side may be used to fix the protective material body 10 to the electric wire 7 .

The fixing member 20 does not have to be fixed to the electric wire 7 by wrapping the tape around it. For example, the fixing member 20 may be fixed by another fixing method, such as by using an adhesive.
The fixing member 20 is not limited to a clamp and may be changed to another member such as a band (cable tie).

The interference portion 9 is not limited to a welding burr, and may be any portion that may cause damage to the outer circumferential surface of the electric wire 7 .
The electric wire 7 is not limited to a structure in which the hard protective layer 15 and the bend-permitting protective layer 16 are coated around the electric wire 7. For example, the electric wire 7 may have a structure without these coating materials, or may have a structure in which the electric wire 7 is protected around the electric wire 7 by a coating material having a different function.

The electric wire routing location 2 is not limited to the floor surface 3 or the vertical wall 4 inside the vehicle, and may be changed to other locations, such as a side wall of the vehicle body.
