[0009] [Description of embodiments of this disclosure] First, the implementation schemes of this disclosure will be listed and explained.

[0010] The wiring components disclosed herein are as follows.

[0011] (1) A wiring component comprising: a first wiring body including a first sheet and a first linear transmission member whose contact portion is directly fixed to the first sheet; a second wiring body including a second sheet and a second linear transmission member whose contact portion is directly fixed to the second sheet; and a fixing portion for fixing the first sheet and the second sheet, wherein the first linear transmission member has a first transmission line body and a first covering layer covering the first transmission line body, the second linear transmission member has a second transmission line body and a second covering layer covering the second transmission line body, wherein the first sheet and the first covering layer are each formed of a first resin material, and the second sheet and the second covering layer are each formed of a second resin material different from the first resin material, wherein in the fixing portion, the second resin material fills the holes formed on the first sheet in the overlapping portion of the first sheet and the second sheet.

[0012] According to the wiring component of (1), since the first sheathing layer and the first sheet of the first linear transmission component are made of the same first resin material, direct fixation at the contact points can be firmly achieved. Since the second sheathing layer and the second sheet of the second linear transmission component are made of the same second resin material, direct fixation at the contact points can be firmly achieved. Since the second resin material fills the holes in the first sheet to form a fixing part, direct fixation at the contact points can be firmly achieved even if the first sheet and the second sheet are made of different resin materials. Based on these, various linear transmission components with different sheathing materials can be well fixed by direct fixation at the contact points. Moreover, since the sheets can be fixed to each other by direct fixation at the contact points, the number of fixing elements using other fixing methods different from direct fixation at the contact points can be reduced.

[0013] (2) In the wiring component of (1), an additional sheet portion may be provided, which is configured to cover the hole on the side opposite to the second sheet relative to the first sheet. The additional sheet portion is formed of the second resin material, and the additional sheet portion and the second sheet are directly fixed to each other through the hole at the contact portion. This improves the strength of the fixing portion.

[0014] (3) In the wiring component of (2), the size of the hole may be larger than the diameter of the first linear transmission component. This increases the direct fixing area between the second sheet and the additional sheet, thereby improving the strength of the fixing part.

[0015] (4) In the wiring component of (1), the first sheet and the second sheet may overlap only in the fixing part. This reduces the number of components constituting the fixing part.

[0016] (5) In the wiring component of (4), the first sheet may be a nonwoven fabric, and the hole may be the gap between the fibers constituting the nonwoven fabric. Thus, the gap between the fibers constituting the nonwoven fabric can be used as a hole, eliminating the need to separately create holes for fixing parts on the first sheet.

[0017] (6) In the wiring component of (4), the first sheet may be a mesh sheet, and the hole may be a hole in the mesh sheet. Thus, the hole in the mesh sheet can be used as a hole for the fixing part without the need to make a hole for the fixing part separately on the first sheet.

[0018] (7) In any of (1) to (6) of the wiring components, the softening point of the first resin material may be higher than that of the second resin material. Thus, while suppressing the softening of the periphery of the hole in the first sheet, the second resin material can easily penetrate into the hole of the first sheet.

[0019] (8) In the wiring component of (7), the first resin material may be polyolefin and the second resin material may be polyvinyl chloride. Thus, it is easy to firmly integrate the linear transmission component with the polyolefin coating and the linear transmission component with the polyvinyl chloride coating.

[0020] [Details of the embodiments disclosed herein] Specific examples of wiring components of this disclosure are described below with reference to the accompanying drawings. Furthermore, this disclosure is not limited to these examples, as indicated by the claims, and is intended to include all modifications within the same meaning and scope as the claims.

[0021] [Implementation Method 1] The wiring components involved in Embodiment 1 will be described below. Figure 1This is a plan view showing the wiring component 10 according to Embodiment 1. Figure 2 It is along Figure 1 A sectional view along line II-II. Figure 3 This is a diagram illustrating an example of a method for manufacturing the wiring component 10.

[0022] The wiring assembly 10 includes a first wiring body 20, a second wiring body 30, and a fixing part 40. The first wiring body 20 and the second wiring body 30 are both flat wiring bodies. Here, "flat" means that the dimension in the thickness direction is smaller than the dimension in the width direction and the dimension in the extension direction, respectively. The first wiring body 20 and the second wiring body 30 overlap each other in the thickness direction. The fixing part 40 fixes the first wiring body 20 and the second wiring body 30, maintaining their overlapping state. The wiring assembly 10 formed by the overlapping of the first wiring body 20 and the second wiring body 30 can also be flat.

[0023] The first wiring harness 20 includes a first sheet 21 and a first linear transmission member 24. The first linear transmission member 24 is fixed to the first sheet 21. The first linear transmission member 24 has a first transmission line body 25 and a first covering layer 26. The first covering layer 26 covers the first transmission line body 25.

[0024] The second wiring harness 30 includes a second sheet 31 and a second linear transmission member 34. The second linear transmission member 34 is fixed to the second sheet 31. The second linear transmission member 34 has a second transmission line body 35 and a second covering layer 36. The second covering layer 36 covers the second transmission line body 35.

[0025] The first linear transmission member 24 and the second linear transmission member 34 are linear members that transmit electricity or light, i.e., linear transmission members. For example, the linear transmission member can be an ordinary electric wire with a core wire and an insulating sheath surrounding the core wire. For example, the linear transmission member can also be a shielded wire with the sheath covered by a shielding layer and an outer sheath. The shielding layer can be conductor foil or braided material, etc. The linear transmission member can also be a stranded wire made of multiple wires twisted together. The linear transmission member can also be an optical fiber, etc.

[0026] Linear transmission components for transmitting electricity can be various signal lines or power lines. They can also be used as antennas, coils, etc., to send or receive signals or power into or from space. Furthermore, linear transmission components can be a single linear object or a composite of multiple linear objects (such as stranded wires, cables that combine multiple linear objects and cover them with a sheath).

[0027] For example, the first linear transmission member 24 is a first wire comprising a first core wire as the first transmission line body 25 and a first insulating sheath 26 covering the first core wire. The first sheath 26 is a layer exposed on the surface of the first linear transmission member 24. Therefore, the material of the surface of the first linear transmission member 24 is the same material that forms the first sheath 26. Here, the first linear transmission member 24 does not have any other layer between the first transmission line body 25 and the first sheath 26. The first linear transmission member 24 may also have other layers between the first transmission line body 25 and the first sheath 26 (e.g., an intermediate insulating sheath covering the core wire and a shielding layer covering the intermediate insulating sheath).

[0028] For example, the second linear transmission member 34 may be a second wire comprising a second core wire as the body 35 of the second transmission line and a second insulating sheath 36 covering the second core wire. The second sheath 36 is a layer exposed on the surface of the second linear transmission member 34. Therefore, the material of the surface of the second linear transmission member 34 is the same material that forms the second sheath 36. Here, the second linear transmission member 34 does not have any other layer between the second transmission line body 35 and the second sheath 36. The second linear transmission member 34 may also have other layers between the second transmission line body 35 and the second sheath 36 (e.g., an intermediate insulating sheath covering the core wire and a shielding layer covering the intermediate insulating sheath).

[0029] For example, connectors C are provided at the ends of the first linear transmission member 24 and the second linear transmission member 34. The wiring member 10 is connected to a device or the like via connectors C. The first linear transmission member 24 and the second linear transmission member 34 can be connected to each other via the same connector C. Alternatively, the first linear transmission member 24 can be connected to a first connector, and the second linear transmission member 34 can be connected to a second connector, which is different from the first connector. The first connector and the second connector can be connected to each other via different mutual connectors. Alternatively, the first connector and the second connector can be stacked to form a single connector, which is then connected to a mutual connector.

[0030] The first sheet 21 and the second sheet 31 are composed of sheet members. Each sheet member includes a weld layer. The weld layer contains a resin material, preferably a thermoplastic resin material. The resin material of the weld layer softens and welds to the object to be welded.

[0031] The structure of the welded layer is not particularly limited. For example, the welded layer can be a sheet with a uniform solid cross-section (also known as a non-foamed sheet or a solid sheet, etc.). Alternatively, the welded layer can also be a foamed sheet. Furthermore, the welded layer can also be a sheet of fibrous material such as woven fabric, machine-woven fabric, or non-woven fabric.

[0032] The sheet member can have a single-layer structure consisting of a welded layer. The sheet member can also have a multi-layer structure. When the sheet member has a multi-layer structure, preferably, the welded layer appears on at least one main surface of the sheet member. When the sheet member has a multi-layer structure, the sheet member can also have additional layers stacked on top of the welded layer.

[0033] The additional layer is formed of a different material from the weld layer or has a different structure. The additional layer enhances the original function of the weld layer or adds functions not present in the weld layer to the sheet component. The material constituting the additional layer can be metal or the like, in addition to the materials described for the weld layer. The structure of the additional layer can be any of the structures described for the weld layer. The weld layer and the additional layer can be formed to the same size (the same planar shape). Alternatively, one of the weld layer and the additional layer can be larger than the other. The weld layer and the additional layer can be fixed entirely in contact area. Alternatively, only a portion of the contact area of ​​the weld layer and the additional layer can be fixed.

[0034] The sheet component can be a flexible component. For example, the sheet component can be flexible enough to follow the bending of a fixed linear transmission component. Each wiring element can be bent in the thickness direction (a bend such that the crease runs along the main surface of the sheet component).

[0035] The planar shape of the sheet component is formed to correspond to the path of the linear transmission component. Figure 1 In the example shown, the sheet component includes multiple ( Figure 1 The example shown has two straight path sections. The intersection of multiple straight path sections is called a curved path section. A curved path section is a section that bends according to the curved path of the linear transmission member. A sheet member can also be composed of a single straight path section. Figure 1 In the example shown, the sheet member does not have branches. The sheet member can also have branches. At the branches of the sheet member, the linear transmission member can branch.

[0036] The fixing part 40 is the part where the first sheet 21 and the second sheet 31 are fixed. The fixing part 40 is formed by direct fixing through the contact part. Figure 1 In addition to the fixing part 40, a wire fixing part 50 is shown, in which the first linear transmission member 24 and the first sheet 21 are directly fixed based on the contact portion. The wire fixing part, in which the second linear transmission member 34 and the second sheet 31 are directly fixed based on the contact portion, may also be provided in the same position as the wire fixing part 50. The fixing of the first linear transmission member 24 to the first sheet 21 and the fixing of the second linear transmission member 34 to the second sheet 31 are also respectively directly fixed based on the contact portion.

[0037] Here, direct fixing of contact parts refers to fixing the contacting parts of two components that are to be fixed together directly and tightly without the use of a separate adhesive or the like. In direct fixing of contact parts, for example, it can be considered to fix them tightly by melting the resin contained in at least one of the two components that are to be fixed together.

[0038] When the contact area is directly fixed, the resin can be melted by heat or by solvent. That is, the direct fixing of the contact area can be based on either heat or solvent. Preferably, the direct fixing based on heat is preferable.

[0039] At this point, the means by which the contact points are directly fixed are not particularly limited, and known methods such as fusion deposition, welding, and fusion bonding can be used. For example, when achieving a state of direct fixation of the contact points based on heat through fusion deposition, various fusion deposition methods such as ultrasonic fusion deposition, heat and pressure fusion deposition, hot air fusion deposition, and high-frequency fusion deposition can be used. Furthermore, if a state of direct fixation of the contact points is achieved through these methods, then the two components being fixed become a state of direct fixation of the contact points based on that method. Specifically, for example, if a state of direct fixation of the contact points is achieved through ultrasonic fusion deposition, then the two components being fixed become a state of direct fixation of the contact points based on ultrasonic fusion deposition.

[0040] The weld layer of the first sheet 21 and the first coating layer 26 are each formed of a first resin material. The weld layer of the second sheet 31 and the second coating layer 36 are each formed of a second resin material. Here, the first resin material and the second resin material are the main components of each sheet 21, 31 and each coating layer 26, 36. The first resin material and the second resin material are different resin materials. Different resin materials mean that the types of resins are different. Therefore, even if the degree of polymerization, the amount of additives, etc. are different, as long as the types of resins as main components are the same, they can be regarded as the same resin materials.

[0041] For example, PVC (polyvinyl chloride) and polyolefins can be used as the first and second resin materials. PP (polypropylene) and PE (polyethylene) are types of polyolefins. The first resin material can be either PVC or a polyolefin, and the second resin material can be either PVC or a polyolefin. Here, the first resin material is a polyolefin, and the second resin material is PVC.

[0042] The fixing strength of directly fixing the contact points of the first resin materials to each other is higher than the fixing strength of directly fixing the contact points of the first resin materials to the second resin materials. Similarly, the fixing strength of directly fixing the contact points of the second resin materials to each other is higher than the fixing strength of directly fixing the contact points of the first resin materials to the second resin materials. For example, under the same conditions, when the first linear transmission member 24 is directly fixed to the first sheet 21 and the second sheet 31 at their respective contact points, the fixing force between the first linear transmission member 24 and the first sheet 21 is greater than the fixing force between the first linear transmission member 24 and the second sheet 31. Likewise, under the same conditions, when the second linear transmission member 34 is welded to the first sheet 21 and the second sheet 31 respectively, the fixing force between the second linear transmission member 34 and the second sheet 31 is greater than the fixing force between the second linear transmission member 34 and the first sheet 21.

[0043] Here, in the wire fixing part 50 where the same resin materials are directly fixed to each other at the contact points, sufficient fixing strength can be easily obtained. In contrast, in the fixing part 40 where the first and second resin materials are directly fixed at the contact points, if the planar portions of solid sheets are stacked together and directly fixed at the contact points, sufficient fixing strength may not be obtained. Here, in the overlapping portion of the first sheet 21 and the second sheet 31 in the fixing part 40, the second resin material of the second sheet 31 fills the holes 22 formed on the first sheet 21. Therefore, even in the fixing part 40 where the first and second resin materials are directly fixed at the contact points, sufficient fixing strength can be easily obtained.

[0044] For example, the fixing part 40 includes a hook portion 44 disposed around the hole 22. The hook portion 44 is formed by filling the hole 22 formed in the first sheet 21 with a second resin material. The hook portion 44 is a portion of the second resin material located on the side opposite to the second sheet 31 relative to the first resin material, thereby hooking onto the first resin material. By providing this hook portion 44, the fixing strength of the fixing part 40, where the first resin material and the second resin material are directly fixed at the contact area, can be strengthened.

[0045] The fixing part 40 may be made solely of the second resin material derived from the second sheet 31. In this case, the hook-on part 44 is made solely of the second resin material that overflows from the hole 22 and originates from the second sheet 31. The fixing part 40 may also be made of a combination of the second resin material derived from the second sheet 31 and second resin material derived from other components different from the second sheet 31. In this case, the hook-on part 44 may also be made of a combination of the second resin material derived from the second sheet 31 and second resin material derived from other components different from the second sheet 31.

[0046] Here, the wiring component 10 includes an additional sheet portion 42. The additional sheet portion 42 is configured to cover the hole 22 on the side opposite to the second sheet 31 relative to the first sheet 21. The additional sheet portion 42 is formed of a second resin material. The additional sheet portion 42 and the second sheet 31 are directly fixed to each other at the contact point through the hole 22. By providing the additional sheet portion 42, the latching portion 44 can be strengthened.

[0047] The additional sheet portion 42 can be formed larger than the hole 22. The additional sheet portion 42 may have a central portion 43 (the portion housed in the hole 22) overlapping with the hole 22, and an outer peripheral portion 44 extending outward from the central portion 43 and overlapping the periphery of the hole 22 in the first sheet 21. The central portion 43 and the second sheet 31 are directly fixed to each other at the contact points via the hole 22. The outer peripheral portion 44 and the first sheet 21 can also be directly fixed to each other at the contact points.

[0048] The additional sheet portion 42 can be made of the same sheet member as the second sheet 31. The additional sheet portion 42 can have the same hardness as the second sheet 31. The additional sheet portion 42 can also be formed to be harder than the second sheet 31. In this case, even if the outer peripheral portion 44 of the additional sheet portion 42 is not directly fixed to the contact portion of the first sheet 21, the additional sheet portion 42 can easily be hooked onto the periphery of the hole 22.

[0049] Here, the additional sheet portion 42 and the second sheet 31 are separate from each other except for the fixing portion 40. The additional sheet portion 42 and the second sheet 31 may also be connected except for the fixing portion 40. For example, the additional sheet portion 42 may be formed by folding back the portion adjacent to the hole 22 in the sheet member constituting the second sheet 31. The portion adjacent to the hole 22 in the sheet member constituting the second sheet 31 may be the portion located outside the hole 22 along the width direction of the sheet member, or it may be the portion located beside the hole 22 along the extension direction of the linear transmission member.

[0050] Here, hole 22 is a through hole additionally machined into the first sheet 21. For example, if the first sheet 21 is a solid sheet, holes 22 may not be formed in the first sheet 21 except at specific locations such as the fixing part 40. Alternatively, if the first sheet 21 is a sheet member having holes originating from the sheet member, the hole 22 in the fixing part 40 may be a hole separately provided from the hole originating from the sheet member. The hole originating from the sheet member may be, for example, the gap between fibers of a nonwoven fabric. The shape of hole 22 is not particularly limited and can be appropriately set. For example, the shape of hole 22 may be square or circular.

[0051] like Figure 3As shown, with the second sheet 31 and the additional sheet portion 42 located on both sides of the hole 22, the first sheet 21, the second sheet 31, and the additional sheet portion 42 are welded together by a welding machine 80 or the like to form the fixing portion 40. The welding machine 80 may be, for example, an ultrasonic welding machine with a welding head and an anvil.

[0052] Here, a hole 22 is formed in a fixing part 40. Multiple holes 22 may also be formed in a fixing part 40. The additional sheet part 42 may be configured to cover the portion between the multiple holes 22 in the first sheet 21. Thus, the additional sheet part 42 can easily be engaged with the portion between the multiple holes 22 in the first sheet 21.

[0053] The size of the hole 22 is not particularly limited and can be appropriately set. For example, the size of the hole 22 can be larger than or smaller than the diameter of the first linear transmission member 24. When multiple linear transmission members of different sizes are used as the first linear transmission member 24, the first linear transmission member 24 compared with the size of the hole 22 can be the smallest linear transmission member. Here, for example... Figure 3 As shown, the size D1 of the holes 22 in the parallel direction (width direction of the first sheet 21) of the plurality of first linear transmission members 24 is greater than the diameter D2 of the first linear transmission member 24. The size of the holes 22 in the extension direction of the first linear transmission member 24 may also be greater than the diameter of the first linear transmission member 24.

[0054] The softening point of the first resin material is higher than that of the second resin material. Therefore, when the first sheet 21 and the second sheet 31 are directly fixed at the contact point, the deformation is mainly caused by the second resin material.

[0055] Here, the first resin material is a polyolefin, and the second resin material is PVC. Therefore, it is easy to set the softening point of the first resin material to be higher than that of the second resin material. Furthermore, the softening point can be adjusted by the degree of polymerization of the resin materials and by using additives. For example, the softening point of the first resin material can be below 100 degrees Celsius, while the softening point of the second resin material can be above 100 degrees Celsius. The softening point can also be referred to as the melting point.

[0056] The fixing part 40 (hole 22) is provided at both ends of the sheet member along the width direction. The two ends of the sheet member along the width direction serve as fixing allowance for the fixing part 40 (hole 22). The fixing part 40 (hole 22) at both ends of the sheet member serves as a wire arrangement part for arranging the linear transmission member. The fixing part 40 (hole 22) may also be provided between multiple linear transmission members.

[0057] The fixing part 40 (hole 22) and the wire fixing part 50 are provided at multiple locations spaced apart along the extension direction of the linear transmission member. Figure 1 In the example shown, the fixing part 40 and the wire fixing part 50 are positioned at the same location along the extension direction of the linear transmission member. Alternatively, the fixing part 40 and the wire fixing part 50 may be positioned at different locations along the extension direction of the linear transmission member.

[0058] Figure 1 In the example shown, the sheet member has a fixing allowance even at positions where the fixing part 40 is not provided, along the extension direction of the linear transmission member. Alternatively, the sheet member may be configured such that no fixing allowance is provided at positions where the fixing part 40 is not provided, along the extension direction of the linear transmission member. In this case, the fixing allowance is formed as a protruding sheet that partially protrudes from the wire arrangement section at the positions where the fixing part 40 is provided.

[0059] Here, in the wire arrangement section of the sheet component, the first sheet 21 and the second sheet 31 are directly fixed without contact. Here, in the wire arrangement section of the sheet component, the first sheet 21 and the second sheet 31 do not contact each other.

[0060] At least one of the first linear transmission member 24 and the second linear transmission member 34 may be disposed between the first sheet 21 and the second sheet 31. Here, the second linear transmission member 34 is disposed between the first sheet 21 and the second sheet 31. The first linear transmission member 24 may also be disposed between the first sheet 21 and the second sheet 31. Both the first linear transmission member 24 and the second linear transmission member 34 may also be disposed between the first sheet 21 and the second sheet 31.

[0061] <Effects, etc.> According to the wiring component 10 configured as described above, since the first coating layer 26 and the first sheet 21 of the first linear transmission component 24 are made of the same first resin material, direct fixation at the contact points can be firmly achieved. Since the second coating layer 36 and the second sheet 31 of the second linear transmission component 34 are made of the same second resin material, direct fixation at the contact points can be firmly achieved. Since the second resin material fills the holes 22 of the first sheet 21 to form a fixing part 40, direct fixation at the contact points can be firmly achieved even if the first sheet 21 and the second sheet 31 are made of different resin materials. Based on these, various linear transmission components with different coating materials can be well fixed by direct fixation at the contact points. Moreover, since the sheets 21 and 31 can be fixed to each other by direct fixation at the contact points, the number of fixing elements using other fixing methods different from direct fixation at the contact points can be reduced. In addition, separate sheet components can be prepared as the first sheet 21 and the second sheet 31. As a result, universal sheet components can be used as the first sheet 21 and the second sheet 31, and cost reduction can be achieved.

[0062] Furthermore, the additional sheet portion 42 and the second sheet 31 are directly fixed at the contact point via the hole 22. This improves the strength of the fixing portion 40.

[0063] Furthermore, the size of the hole 22 is larger than the diameter of the first linear transmission member 24. As a result, the direct fixing area at the contact point between the second sheet 31 and the additional sheet portion 42 can be expanded, thereby increasing the strength of the fixing portion 40.

[0064] Furthermore, the softening point of the first resin material is higher than that of the second resin material. Therefore, while suppressing softening of the periphery of the holes 22 in the first sheet 21, the second resin material can easily penetrate into the holes 22 of the first sheet 21.

[0065] Furthermore, the first resin material is polyolefin, and the second resin material is polyvinyl chloride. This facilitates the strong integration of a linear transport member coated with polyolefin and a linear transport member coated with polyvinyl chloride.

[0066] [Implementation Method 2] The wiring components involved in Embodiment 2 will be described. Figure 4 This is a cross-sectional view showing the wiring component 110 according to Embodiment 2. Figure 5 yes Figure 4 An enlarged view of region A. Furthermore, in the description of this embodiment, the same reference numerals are used for the same constituent elements as described herein, and their descriptions are omitted.

[0067] The difference from the wiring component 10 described above is that the additional sheet portion 42 is not provided in the fixing portion 140 of the wiring component 110. In the fixing portion 140, only the first sheet 121 and the second sheet 31 overlap.

[0068] Here, the hole 122 originates from the hole in the sheet member constituting the first sheet 121. The first sheet 121 is a sheet with a plurality of holes 122, some of which are used for the fixing portion 140. The first sheet 121 also has holes 122 that are not used for the fixing portion 140. The wire arrangement portion in the first sheet 121 also has holes 122 that are not used for the fixing portion 140.

[0069] Figure 5 In the example shown, the first sheet 121 is a nonwoven fabric. Holes 122 are the gaps between the fibers 123 constituting the nonwoven fabric. In this case, a softened second resin material enters the gaps between the fibers 123. A portion of the fibers 123 is wrapped by the second resin material. The second resin material wrapping the fibers 123 becomes the hook portion 144.

[0070] Figure 6 The figure shows a modified example of the fixing part 140. Figure 6In the shown fixing part 140A, the first sheet 121A is a mesh sheet. Holes 122A are openings (mesh) in the mesh sheet. For example, the mesh sheet is composed of multiple warp yarns 123A and multiple weft yarns 123B. The mesh portion located between the multiple warp yarns 123A and multiple weft yarns 123B is designated as hole 122A. Softened second resin material passes through hole 122A and wraps around to the side furthest from the second sheet 31 relative to the warp yarns 123A or weft yarns 123B. A portion of the warp yarns 123A or weft yarns 123B is wrapped by the second resin material. The second resin material wrapping the warp yarns 123A or weft yarns 123B becomes the hook portion 144A.

[0071] According to the wiring member 110 equipped with such fixing parts 140 and 140A, similar to the wiring member 10 described above, various linear transmission members with different sheathing materials can be well fixed by direct fixing through the contact parts. Moreover, according to the wiring member 110, since the additional sheet part 42 is not provided, the number of components constituting the fixing parts 140 and 140A can be reduced accordingly compared with the wiring member 10.

[0072] Figure 5 In the shown fixing part 140, the hole 122 is the gap between the fibers 123 constituting the nonwoven fabric. In this case, the gap between the fibers 123 constituting the nonwoven fabric can be used as the hole 122, eliminating the need to separately open the hole 122 for fixing part 140 on the first sheet 121.

[0073] Figure 6 In the shown fixing part 140A, the hole 122A is a hole in the mesh sheet. In this case, the hole in the mesh sheet can be used as the hole 122A of the fixing part 140A as is, without the need to separately open the hole 122A for the fixing part 140A on the first sheet 121A.

[0074] [Postscript] The examples above illustrate that wiring components 10 and 110 do not have wiring bodies other than the first wiring body 20 and the second wiring body 30, but this is not a necessary structure. For example, Figure 7As shown, the wiring component 210 may also include wiring bodies 60 other than the first wiring body 20 and the second wiring body 30. A third wiring body 60 having a third linear transmission member 64 may also be disposed between the first sheet 21 and the second sheet 31. Similar to the first wiring body 20, the third wiring body 60 may have a third sheet 61 for direct fixation to the contact portion of the third linear transmission member 64. The third sheet 61 may be fixed to both the first sheet 21 and the second sheet 31. Alternatively, the third sheet 61 may not be fixed to either the first sheet 21 or the second sheet 31. The third wiring body 60 may also not have a third sheet 61. The third wiring body 60 may also be held in a stacked state simply by being wrapped between the first wiring body 20 and the second wiring body 30. The third wiring body 60 may also be stacked on the outside of the second wiring body 30. In this case, the third sheet 61 is made of a second resin material, and at the fixing part 40, the third sheet 61 can be directly fixed to the second sheet 31 by the contact portion.

[0075] Furthermore, the structures described in the above embodiments and variations can be appropriately combined as long as they do not contradict each other. Symbol Explanation
