[0006] Problems to be solved by the invention

[0007] In wiring components, such as the wire harness described in Patent Document 1, where a bundle of linear transmission components is arranged on a base component, it is desirable to reduce the height. However, as the number of connection destinations increases, the number of linear transmission components constituting the bundle increases, and the bundle becomes larger.

[0021] [Description of Embodiments of the Present Disclosure]

[0022] First, embodiments of the present disclosure will be described below.

[0023] The wiring member of the present disclosure is as follows.

[0024] (1) A wiring component comprising a plurality of linear transmission components, a base component on at least one surface of which the plurality of linear transmission components are arranged, and a cover component for maintaining the plurality of linear transmission components in a state of being arranged on the base component, the plurality of linear transmission components having a base component arrangement section arranged on the base component and a non-base component arrangement section not arranged on the base component, wherein in the base component arrangement section, the plurality of linear transmission components are divided into at least a first linear transmission component bundle and a second linear transmission component bundle, the cover component being fixed to the base component at both sides of and between the first linear transmission component bundle and the second linear transmission component bundle, and covering the first linear transmission component bundle and the second linear transmission component bundle, and in the non-base component arrangement section, the plurality of linear transmission components having a large bundle portion for bundling the first linear transmission component bundle and the second linear transmission component bundle. The plurality of linear transmission components extend as a large bundle in the non-base component placement area and are divided into a first linear transmission component bundle and a second linear transmission component bundle in the base component placement area. This allows the height of the wiring component to be reduced in the base component placement area. Furthermore, the cover member is fixed to the base component at positions on both sides of the first and second linear transmission component bundles and between them. This prevents the linear transmission components of the respective linear transmission component bundles from becoming intermingled and causing the wiring component height to reach an undesirable height. Consequently, in a wiring component formed by placing the linear transmission component bundles on the base component, the height on the base component can be reduced.

[0025] (2) In the wiring member of (1), a plurality of fixing portions for fixing the cover member to the base member may be provided at intervals along the extending direction of the first and second linear transmission member bundles, and a transfer region for transferring at least one linear transmission member constituting the first linear transmission member bundle to the second linear transmission member bundle may be provided between the plurality of fixing portions. Thus, when a large bundle is divided into a plurality of linear transmission member bundles, it is not necessary to set a linear transmission member bundle for each path, and it is easy to appropriately set the number of linear transmission member bundles, the thickness of each linear transmission member bundle, and the like.

[0026] (3) In the wiring member of (2), two or more of the linear transmission members constituting the first linear transmission member bundle may be transferred to the second linear transmission member bundle in one transfer region. This can prevent the transfer region from being widely dispersed on the base member.

[0027] (4) In any one of the wiring components described in (1) to (3), the base component and the cover component may be fixed by welding. This allows the wiring component to omit a component for fixing the cover component to the sheet.

[0028] (5) In any of the wiring components described in (1) to (4), at least the plurality of linear transmission components constituting the first linear transmission component bundle may include a linear transmission component having a coating layer formed of a material different from a material constituting the at least one surface. Thus, the linear transmission components, which are difficult to be directly welded to the base component, are retained on the base component by the cover component.

[0029] (6) In any one of the wiring components described in (1) to (5), when the plurality of linear transmission components covered by the cover component are each a first linear transmission component, the wiring component may further include a second linear transmission component including a transmission line body and a coating layer covering the transmission line body and disposed on the at least one surface, wherein the coating layer of the second linear transmission component is fused to the at least one surface. Thus, the second linear transmission component is directly fixed to the base component.

[0030] (7) In any of the wiring components described in (1) to (6), the first linear transmission component bundle may include a curved portion arranged in a path curved on at least one of the surfaces, and the cover member may be fixed to the base member at positions on both sides of the curved portion. This prevents the linear transmission component and the base member from being misaligned along the direction in which the linear transmission component extends when the linear transmission component is pulled outward from the base member.

[0031] (8) In any of the wiring components described in (1) to (7), the first linear transmission component bundle may include a tape-wound portion wrapped with adhesive tape, and the cover member may be fixed to the base member at a position lateral to a portion covering the tape-wound portion. Thus, the linear transmission component bundle is less likely to unravel at the tape-wound portion, and the linear transmission component is prevented from being caught between the cover member and the base member when the cover member and the base member are fixed.

[0032] (9) In any one of the wiring components described in (1) to (8), the base component may be provided with an excess length absorbing portion for absorbing excess length of the linear transmission component. Thus, the base component absorbs tolerances of the linear transmission component.

[0033] (10) In the wiring member of (9), a first fixing portion and a second fixing portion for fixing the cover member to the base member may be provided at intervals along the extending direction of the first and second linear transmission member bundles, and the excess length absorbing portion may include a detour portion in which the path of the linear transmission member between the first and second fixing portions is extended along a detour that is longer than the shortest path. Thus, the excess length absorbing portion can be easily provided.

[0034] (11) In the wiring component of (10), the cover member may include a portion covering the detour path portion. This prevents the excess length of the linear transmission member from protruding outward.

[0035] (12) In any of the wiring components described in (1) to (11), the cover component may include a plurality of strip-shaped sheets arranged at intervals along the extending direction of the first and second linear transmission component bundles, and the plurality of strip-shaped sheets may be fixed to the base component at positions on both sides of and between the first and second linear transmission component bundles. Thus, the cover component need not be provided on the entire base component.

[0036] (13) In any of the wiring components described in (1) to (12), the first and second linear transmission component bundles may extend outward from a plurality of end portions of the base component. This facilitates maintaining the linear transmission component divided into a plurality of linear transmission component bundles on the base component.

[0037] [Details of the embodiments of the present disclosure]

[0038] Specific examples of the wiring member of the present disclosure will be described below with reference to the accompanying drawings. The present disclosure is not limited to these examples, but is defined by the claims and is intended to encompass all modifications within the meaning and scope of the claims.

[0039] [Implementation Method 1]

[0040] Next, the wiring member according to the first embodiment will be described. Figure 1 This is a schematic plan view showing the wiring member 10 according to the first embodiment. Figure 2 and Figure 4 yes Figure 1 A partial enlarged view of . Figure 2 and Figure 4 Enlarge the parts that are different from each other. Figure 3 It is along Figure 4 A cross-sectional view obtained by cutting along line IV-IV.

[0041] The wiring component 10 includes a base member 20, a plurality of wires 30, and a cover member 40. Here, the wiring component 10 further includes a linear transmission member 50. The wires 30 and the linear transmission member 50 are fixed to the base member 20. The wires 30 and the linear transmission member 50 are fixed to the base member 20 in different ways. The wires 30 are an example of a first linear transmission member, and the linear transmission member 50 is an example of a second linear transmission member.

[0042] The electric wire 30 and the linear transmission component 50 are arranged on at least one surface of the base member 20. The surface of the base member 20 on which the electric wire 30 and the linear transmission component 50 are arranged is referred to as the arrangement surface 21. Here, a single surface of the base member 20 is referred to as the arrangement surface 21. The base member 20 may have any shape or structure. Here, an example in which the base member 20 is formed into a sheet shape is described.

[0043] Here, the base member 20 is shaped to follow the paths of the electric wires 30 and the linear transmission member 50. Specifically, the base member 20 has a portion that curves in accordance with the curved paths of the electric wires 30 and the linear transmission member 50. Furthermore, the base member 20 has a portion that branches in accordance with the branched paths of the electric wires 30 and the linear transmission member 50. The base member 20 may also be formed in a large square shape, for example.

[0044] Here, the base member 20 has a two-layer structure of a first layer 22 and a second layer 24. The base member 20 may have a one-layer structure or a structure of three or more layers.

[0045] One surface of the first layer 22 serves as the placement surface 21 of the base member 20. The wires 30 and the linear transmission member 50 are secured to the first layer 22. Here, the first layer 22 serves as the base member-side welding layer. The welding layer comprises a resin material, preferably a thermoplastic resin material. The resin material of the welding layer softens and fuses to the welding partner. The type of resin material is not particularly limited; polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and the like can be used.

[0046] The structure of the first layer 22 is not particularly limited. For example, the first layer 22 may be a sheet having a uniform, solid cross-section (also referred to as a non-foamed sheet or solid sheet). Alternatively, the first layer 22 may be a foamed sheet. Alternatively, the first layer 22 may be a sheet of fiber material such as knitted fabric, woven fabric, or non-woven fabric.

[0047] The second layer 24 is formed of a different material or has a different structure than the first layer 22. The second layer 24 enhances the functions of the first layer 22 or adds functions not provided by the first layer 22 to the base member 20. In addition to the materials described above for the first layer 22, the second layer 24 may also be made of metal or the like. The second layer 24 may also have any of the structures described above for the first layer 22. One surface of the second layer 24 serves as the main surface of the base member 20 opposite the placement surface 21.

[0048] While the other surface of the first layer 22 is in contact with the other surface of the second layer 24, the first layer 22 and the second layer 24 are fixed. The method for fixing the first layer 22 and the second layer 24 is not particularly limited, but preferably, they are fixed by welding or bonding. For example, if at least one of the first layer 22 and the second layer 24 is a sheet material with voids on its surface, such as a fiber sheet or a foam sheet, the resin material or adhesive can enter the voids and fix them. This creates a so-called anchoring effect, firmly fixing the first layer 22 and the second layer 24.

[0049] Here, the first layer 22 is described as a solid sheet made of resin, and the second layer 24 is described as a sheet made of fiber material. The first layer 22 and the second layer 24 are fused together. Specifically, the resin in the first layer 22, while still fluid, penetrates between the fibers of the second layer 24 and then hardens. This maintains the resin in the first layer 22 between the fibers of the second layer 24, firmly fixing the first and second layers 22 and 24.

[0050] The first layer 22 and the second layer 24 are formed to be the same size (the same planar shape). The first layer 22 and the second layer 24 may be formed so that one is larger than the other. The entire contact area of the first layer 22 and the second layer 24 is fixed. The first layer 22 and the second layer 24 may be fixed only partially in the contact area.

[0051] The base component 20 can also be a soft component. For example, the base component 20 can be made into a soft component by making the first layer 22 a resin layer with a uniform and solid cross-section made of a soft resin such as soft PVC, and the second layer 24 a non-woven fabric made of PET. For example, the base component 20 can also have flexibility that can follow the bending of the wire 30 and the linear transmission component 50. The wiring component 10 can also be bent in the thickness direction at the portion where the base component 20 is provided (bending such that the fold runs along the main surface of the base component 20). However, the base component 20 can also be a component that cannot bend in the thickness direction. The base component 20 can also be a component that can be bent without cracking when bent in the thickness direction. The base component 20 can also be a component that cannot be bent without cracking when bent in the thickness direction. The base component 20 can also have rigidity that cannot follow the bending of the wire.

[0052] The electric wire 30 is a linear component that transmits electricity. The linear transmission component 50 is a linear component that transmits electricity, light, or the like. The electric wire 30 has a base component placement section and a non-base component placement section. The base component placement section is the section of the electric wire 30 that is placed on the base component 20. The base component placement section is the section of the electric wire 30 that is located on the placement surface 21. The non-base component placement section is the section of the electric wire 30 that is not placed on the base component 20. The non-base component placement section is the section of the electric wire 30 that is located outside the placement surface 21. The base component placement section and the non-base component placement section can be located anywhere on the electric wire 30. Here, the middle portion of the electric wire 30 is designated as the base component placement section, and the ends of the electric wire 30 are designated as the non-base component placement section. The middle portion of the electric wire 30 can also be designated as the non-base component placement section. The ends of the electric wire 30 can also be designated as the base component placement section. Here, the base component placement section is located between the two non-base component placement sections. Alternatively, a non-base component placement section may be provided between two base component placement sections. It suffices to provide at least one base component placement section and at least one non-base component placement section. The base component 20 is formed as a whole in a flat shape. By securing the plurality of electrical wires 30 and the linear transmission member 50 to the base component 20, the wiring member 10 is maintained in a flat configuration within the base component placement section.

[0053] It is assumed that the plurality of wires 30 and the linear transmission component 50 are components that connect components within a vehicle. For example, connectors C are provided at the ends of the wires 30 and the linear transmission component 50. These connectors C are connected to connectors provided on the other component, thereby connecting the wires 30 and the linear transmission component 50 to the other component. In other words, the wiring component 10 is used as a wiring component 10 that electrically (or optically) connects various components within a vehicle or the like. The connectors C may also be fixed to the base component 20.

[0054] The routing of the multiple electrical wires 30 and the linear transmission component 50 is determined based on the location of the components to be connected. By securing the multiple electrical wires 30 and the linear transmission component 50 to the base member 20, the multiple electrical wires 30 and the linear transmission component 50 are maintained along routing paths corresponding to the locations of the components to be connected within the base member arrangement area. The multiple electrical wires 30 and the linear transmission component 50 can also be secured to the base member 20 so that branch lines branch from the main line. The base member 20 can also be configured so that the portion securing the branch lines branches from the portion securing the main line. In this case, the multiple electrical wires 30 and the linear transmission component 50 branch on the base member 20.

[0055] The plurality of wires 30 are divided into a plurality of wire bundles 34 and run in parallel in the base component configuration area. Each wire bundle 34 is a collection of two or more wires 30 from the plurality of wires 30. Here, three wire bundles 34A, 34B, and 34C extend in parallel from the branch area in a first direction. Two wire bundles 34D and 34E extend in parallel from the branch area in a second direction. Two wire bundles 34F and 34G extend in parallel from the branch area in a third direction. The number of wire bundles 34 extending in parallel from the branch area in the first, second, and third directions, respectively, can be any number and can be set as appropriate. By increasing the number of wire bundles 34, for example, the height dimension of the wiring component 10 can be reduced. Furthermore, by decreasing the number of wire bundles 34, for example, the width dimension of the wiring component 10 can be reduced. The wire bundle 34 is an example of a linear transmission component bundle. Any two of the above-mentioned wire bundles 34 can be set as the first linear transmission component bundle and the second linear transmission component bundle. The first linear transmission member bundle and the second linear transmission member bundle are preferably any two of the combinations of parallel electric wire bundles in the above-mentioned electric wire bundle 34 .

[0056] The three wire bundles 34A, 34B, and 34C extend from the base component configuration section to the non-base component configuration section in their divided state and converge in the non-base component configuration section. A large bundle portion 36 is provided in the non-base component configuration section, which is formed by bundling the three wire bundles 34A, 34B, and 34C. The large bundle portion 36 is bound with a binding member such as an adhesive tape TA or a binding strip. The large bundle portion 36 can also be housed in an exterior material such as a corrugated tube or a protective device and bundled. The plurality of wires 30 have a portion extending as the large bundle portion 36 in the non-base component configuration section, and have a portion extending as the three wire bundles 34A, 34B, and 34C on the configuration surface of the base component configuration section. The plurality of wires 30 constituting the large bundle portion 36 are connected to a single connector C1 at one end of the large bundle portion 36. The plurality of wires 30 constituting the large bundle portion 36 can also be branched at one end of the large bundle portion 36 and connected to multiple connectors.

[0057] Here, the portion where the three wire harnesses 34A, 34B, and 34C are transferred to the large bundle portion 36 is located in the non-base component placement section. The three wire harnesses 34A, 34B, and 34C extend from the end portion 20a of the base component 20 to the non-base component placement section in their divided state and are connected to a single connector C1. The portion where the three wire harnesses 34A, 34B, and 34C are transferred to the large bundle portion 36 may also be located in the base component placement section. Furthermore, as described above, the portion where the three wire harnesses 34A, 34B, and 34C are transferred to the large bundle portion 36 is exemplified as the portion where the three wire harnesses 34A, 34B, and 34C are transferred, but the portion where the three wire harnesses 34A, 34B, and 34C are transferred may also be understood as the portion where the width of the harness is smallest due to the large bundle portion. Alternatively, the portion where the height of the harnesses 34A, 34B, and 34C is largest due to the large bundle portion may also be understood as the portion where the three wire harnesses 34A, 34B, and 34C are transferred.

[0058] The two wire bundles 34D and 34E extend, still in a bifurcated state, from the end 20b of the base member 20 to the non-base member area and are connected to a single connector C2. The two wire bundles 34D and 34E are not bundled together in the non-base member area. Furthermore, the wires 30 constituting the wire bundle 34D are not bundled together with tape TA or the like in the non-base member area. The wires 30 constituting the wire bundle 34E are not bundled together with tape TA or the like in the non-base member area.

[0059] The two wire bundles 34F and 34G extend from the end 20c of the base member 20 to the non-base member area, remaining in their bifurcated state, and are connected to separate connectors C3 and C4, respectively. The two wire bundles 34D and 34E are not formed into a large bundle in the non-base member area. The wires 30 comprising the wire bundle 34F are bundled together in the non-base member area using tape TA, etc. The wires 30 comprising the wire bundle 34G are bundled together in the non-base member area using tape TA, etc.

[0060] Sometimes the portion where multiple wire bundles 34 are parallel at the base component configuration interval is called a parallel path portion. Here, there are three parallel path portions, namely, a parallel path portion of three wire bundles 34A, 34B, and 34C, a parallel path portion of two wire bundles 34D and 34E, and a parallel path portion of two wire bundles 34F and 34G. However, there is no need to set up three parallel path portions, and the number of parallel path portions can be one, two, or more than four. It is sufficient to set up at least one parallel path portion. For example, in the case where multiple wires 30 do not branch on the base component 20, the number of parallel path portions is one. In addition, for example, even in the case where multiple wires 30 branch on the base component 20, the number of parallel path portions may also be one. For example, in Figure 1In the case where only one wire bundle extends from the branch area in the second and third directions respectively instead of the two wire bundles 34D, 34E, 34F, and 34G, the number of parallel path portions is one parallel path portion of the three wire bundles 34A, 34B, and 34C.

[0061] A large bundle portion 36 is provided on one of the three parallel path portions. Alternatively, a large bundle portion 36 may be provided on multiple parallel path portions. Preferably, the large bundle portion 36 is provided on the thickest parallel path portion when bundled together. By providing the thickest large bundle portion 36 as a parallel path portion on the base member 20, the height of the wiring member 10 on the base member 20 can be reduced.

[0062] The electric wire 30 includes a core wire 31 and an insulating coating 32. The insulating coating 32 is the outermost layer of the electric wire 30. The linear transmission component 50 includes a transmission wire body 51 and a coating 52. The coating 52 is the outermost layer of the linear transmission component 50. For example, the linear transmission component 50 can be a conventional electric wire having a core wire and a coating surrounding the core wire, or it can be a shielded wire, stranded wire, enameled wire, nichrome wire, optical fiber, or the like. The transmission wire body transmits electricity or light, etc. The transmission wire body is equivalent to the core wire in a coated electric wire and the core and coating in an optical fiber cable.

[0063] The electric wire 30 and the electric power transmission linear transmission member 50 may be various signal lines or various power lines. Parts of the electric wire 30 and the electric power transmission linear transmission member 50 may also be used as antennas, coils, etc. for transmitting or receiving signals or power to or from space.

[0064] The electric wire 30 and the linear transmission member 50 may be a single linear object or a composite of a plurality of linear objects (a twisted wire, a cable in which a plurality of linear objects are assembled and covered with a sheath, etc.).

[0065] The cover member 40 is used to fix the electric wire 30 to the base member 20. The linear transmission member 50 is fixed to the base member 20 without the cover member 40 interposed therebetween.

[0066] The cover member 40 covers the plurality of wire harnesses 34. The cover member 40 is fixed to the configuration surface 21. The cover member 40 is fixed to the configuration surface 21 at positions on both sides of and between the plurality of wire harnesses 34. The wire harnesses 34 are sandwiched between the base member 20 and the cover member 40. An annular portion surrounding the wire harnesses 34 is formed by the base member 20 and the cover member 40. The wire harnesses 34 pass through the internal space of the annular portion. The base member 20 and the cover member 40 are fixed to each other on both sides of the wire harnesses 34. Thus, the wire harnesses 34 are fixed to the base member 20 via the cover member 40.

[0067] The portion that secures the base member 20 to the cover member 40 is referred to as the fixing portion FP. Three or more fixing portions FP are provided at intervals along the parallel direction of the wire bundle 34. Alternatively, the fixing portion FP may be provided continuously throughout the entire wire bundle 34 in the direction in which the wire bundle 34 extends. Here, a plurality of fixing portions FP are provided at intervals along the direction in which the wire bundle 34 extends.

[0068] The base component 20 and the cover component 40 may be fixed in any manner. As the above-mentioned fixing method, it may be fixed at the contact part, fixed at the non-contact part, or both may be used. Here, fixing at the contact part refers to tightly fixing the contact part between the base component 20 and the cover component 40. In addition, fixing at the non-contact part refers to a fixing method that is not fixing at the contact part, for example, sutures, covers, tapes, etc. are used to press the cover component 40 into the base component 20 or to clamp the base component 20 and the cover component 40 and maintain them in this state. Below, it is assumed that the base component 20 and the cover component 40 are in a state of being fixed at the contact part for explanation.

[0069] The above-mentioned contact portion fixing method may be indirect contact portion fixing or direct contact portion fixing, or both methods may be used in different areas. Here, indirect contact portion fixing refers to indirectly adhering and fixing the base component 20 and the cover component 40 via an adhesive, a sticky agent, a double-sided tape, etc. provided therebetween. Alternatively, direct contact portion fixing refers to directly adhering and fixing the base component 20 and the cover component 40 without using an adhesive provided separately. In direct contact portion fixing, for example, it is considered that the base component 20 and the cover component 40 are adhered and fixed by melting the resin contained in at least one of the base component 20 and the cover component 40.

[0070] When achieving the aforementioned direct fixation of the contact points, the resin can be melted by heat or by a flux, for example. In other words, the direct fixation of the contact points can be achieved by heat or by a flux. Preferably, the direct fixation of the contact points is achieved by heat.

[0071] At this time, the means for forming the contact portion in a directly fixed state is not particularly limited, and known means such as welding, fusion bonding, and soldering can be used. Here, the base member 20 and the cover member 40 are directly fixed by welding. The cover member 40 includes a cover member side welding layer.

[0072] The cover part side welding layer is welded to the base part side welding layer. The material and structure of the cover part side welding layer can adopt the material and structure described above for the base part side welding layer. The cover part 40 can be a single-layer structure or a stacked structure formed by stacking multiple layers. When the cover part 40 is a stacked structure, the cover part side welding layer is preferably present on one main surface of the cover part 40. The cover part 40 can be the same structure as the base part 20 or another structure. When the cover part 40 is a different structure from the base part 20, the structure of the cover part 40 is not particularly limited and can be set appropriately. For example, the thickness of the cover part 40 can be the same as that of the base part 20, the thickness of the cover part 40 can be thicker than that of the base part 20, or the thickness of the base part 20 can be thicker than that of the cover part 40.

[0073] Here, the cover member 40 has a different structure from the base member 20. Here, the cover member 40 has a single-layer structure consisting only of the cover member side welding layer. Therefore, one principal surface of the cover member side welding layer constitutes one principal surface of the cover member 40, and the other principal surface of the cover member side welding layer constitutes the other principal surface of the cover member 40.

[0074] The size of the cover member 40 is not particularly limited, but the cover member 40 is preferably formed smaller than the base member 20. The cover member 40 is preferably formed smaller than the base member 20 in at least one of the extension direction and the width direction of the base member 20. Here, the cover member 40 includes a plurality of strip-shaped sheets 42.

[0075] Each strip-shaped sheet 42 is formed to have a smaller dimension than the base member 20 in both the extension direction and the width direction of the base member 20. Each strip-shaped sheet 42 is formed to be shorter than the wire bundle 34 along the extension direction of the wire bundle 34. Each strip-shaped sheet 42 covers a portion of the wire bundle 34 along the extension direction. A plurality of strip-shaped sheets 42 are arranged at intervals along the extension direction of the wire bundle 34. Each strip-shaped sheet 42 covers a plurality of wire bundles 34 arranged at its position. Fixing portions are provided on both sides of the plurality of wire bundles 34 and at positions between them on each strip-shaped sheet 42. By providing a fixing portion FP on each strip-shaped sheet 42, a plurality of fixing portions FP are provided at intervals along the extension direction of the wire bundle 34.

[0076] The wiring harness 34 includes a curved portion 38 arranged along a path curved in the base member arrangement area. The angle of the curved portion 38 is not particularly limited and can be set as desired. For example, if the angle of the straight portion is set to 180 degrees, the angle of the curved portion 38 is 150 degrees. The angle of the curved portion 38 is preferably between 90 and 150 degrees.

[0077] The cover part 40 is fixed to the base part 20 at positions on both sides of the bend 38. Here, the wire harness 34 is not directly connected to the base part 20 and the cover part 40. Therefore, the wire harness 34 can move in the extension direction relative to the base part 20 and the cover part 40. By fixing the cover part 40 to the base part 20 at positions on both sides of the bend 38, the movement of the wire harness 34 in the extension direction is suppressed. The positions on both sides of the bend 38 refer to positions next to the bend start part and the bend end part. That is, the wire harness 34 starts to bend at a position next to the fixed part FP2 side on the other side relative to the fixed part FP1 on one side, and ends to bend at a position next to the fixed part FP1 side on one side relative to the fixed part FP2 on the other side.

[0078] That is, the wire harness 34 extends along the first direction on one side of the curved portion 38 and extends along the second direction on the other side of the curved portion 38. The first direction and the second direction are directions that intersect with each other. In addition, the strip-shaped sheet 42A is set at a position on one side of the curved portion 38. In addition, the strip-shaped sheet 42B is set at a position on the other side of the curved portion 38. If the portion of the wire harness 34 located on one side of the curved portion 38 is pulled toward the end side along the first direction and the wire harness 34 moves, the wire harness 34 interferes with at least one of the strip-shaped sheets 42A, 42B, thereby suppressing the movement. Similarly, if the portion of the wire harness 34 located on the other side of the curved portion 38 is pulled toward the end side along the second direction and the wire harness 34 moves, the wire harness 34 interferes with at least one of the strip-shaped sheets 42A, 42B, thereby suppressing the movement.

[0079] Here, only one branching region is provided. A branching region is a region where one portion of the electric wire branches off from another portion of the electric wire. Alternatively, multiple branching regions may be provided.

[0080] A transition region is provided between the plurality of fixing portions FP. The transition region is a region where at least one of the plurality of wires 30 changes its belonging to the wire bundle 34. Here, a single transition region is provided in the wiring member 10. Alternatively, the wiring member 10 may include multiple transition regions.

[0081] A transition region is provided in a branching region. A transition region provided in a branching region is referred to as a branching transition region. In a branching transition region, some of the plurality of wires 30 belonging to a single wire bundle 34 branch off from another portion of the wires 30, thereby changing the wire bundle 34. In a branching region, some of the wires 30 in the wire bundle may not branch, and the wire bundles 34 may branch off from one another. In this case, the branching region is not considered a branching transition region.

[0082] For example, the parallel transition area may be formed between the strip sheet 42A and the strip sheet 42B so that the wires 30 of one of the three parallel wire bundles 34A, 34B, and 34C are transferred to the other wire bundle 34.

[0083] In one transfer area, two or more electric wires 30 change the electric wire bundle 34 to which they belong. Here, one branch transfer area is provided. In this branch transfer area, a plurality of electric wires 30 change the electric wire bundle 34 to which they belong.

[0084] A transfer pair is a pair of wires 30 that changes the combination of wires 30 in the wire bundle 34 to which they belong in a transfer region. Transfer pairs include parallel transfer pairs and branch transfer pairs. Parallel transfer pairs change the combination of wires 30 in the wire bundle 34 while continuing in parallel without branching after passing through the transfer region. Parallel transfer pairs can occur in both branch transfer regions and parallel transfer regions. Branch transfer pairs change the combination of wires 30 in the wire bundle 34 while branching after passing through the branch transfer region. Branch transfer pairs do not occur in parallel transfer regions.

[0085] Specifically, in Figure 4 In the example shown, if the wire bundle 34A is used as a reference, the wire 30A extends to the wire bundle 34G through the branch transfer area, and the other wires 30 extend to the wire bundle 34F. Therefore, if the wire bundle 34A is used as a reference, the wire 30A and the other wires 30 are parallel transfer wire pairs.

[0086] Taking wire bundle 34B as the reference, wire 30B extends through the transfer area to wire bundle 34D, wire 30C extends to wire bundle 34E, and the remaining wires 30 extend to wire bundle 34G. Therefore, taking wire bundle 34B as the reference, wires 30B and 30C form a parallel transfer pair. Furthermore, wires 30B, 30C, and the remaining wires 30 form a branch transfer pair.

[0087] If the wire bundle 34D is used as a reference, the wire 30B extends to the wire bundle 34B through the branch transfer area, and the wire 30D extends to the wire bundle 34F. Therefore, if the wire bundle 34D is used as a reference, the wires 30B and 30D form a branch transfer pair.

[0088] If the wire bundle 34E is used as a reference, the wire 30C extends to the wire bundle 34B through the branch transfer area, and the other wires 30 extend to the wire bundle 34C. Therefore, if the wire bundle 34E is used as a reference, the wire 30C and the other wires 30 are parallel transfer wire pairs.

[0089] If the wire bundle 34F is used as a reference, the wire 30D extends to the wire bundle 34D through the branch transfer area, and the other wires 30 extend to the wire bundle 34A. Therefore, if the wire bundle 34F is used as a reference, the wire 30D and the other wires 30 form a branch transfer pair.

[0090] If the wire bundle 34G is used as a reference, the wire 30A extends to the wire bundle 34A through the branch transfer area, and the other wires 30 extend to the wire bundle 34B. Therefore, if the wire bundle 34G is used as a reference, the wire 30A and the other wires 30 are a parallel transfer pair.

[0091] Furthermore, if the wire bundle 34C is set as a reference, there are no transferred wire pairs.

[0092] The linear transmission member 50 is disposed in the base member placement section. The coating layer of the linear transmission member 50 is fused to the placement surface 21. The portion where the linear transmission member 50 and the placement surface 21 are fused is referred to as the welded portion WP. The resin material constituting the first layer 22 and the coating layer 52 are of the same type.

[0093] Here, the linear transmission member 50 is welded to the base member 20 at a plurality of locations spaced apart along the extending direction. The linear transmission member 50 may also be fixed to the base member 20 so as to be integrally connected along the extending direction.

[0094] Here, the fixing portion FP and the welding portion WP are provided at the same position along the extension direction in the section where the wire bundle 34 and the linear transmission member 50 are parallel to each other. However, the fixing portion FP and the welding portion WP may be provided at different positions along the extension direction in the section where the wire bundle 34 and the linear transmission member 50 are parallel to each other.

[0095] The linear transmission component 50 includes multiple (two in this case). The linear transmission component 50 may include only one or more than three. When the wiring component 10 includes the linear transmission component 50, at least one linear transmission component 50 is sufficient. The linear transmission component 50 may also be omitted. Figure 2 As shown, the linear transmission member 50 extending outward from the base member 20 together with the plurality of wire bundles 34A, 34B, and 34C is bundled in the large bundle portion 36. The linear transmission member 50 extending outward from the base member 20 together with the plurality of wire bundles 34A, 34B, and 34C does not need to be bundled in the large bundle portion 36.

[0096] Here, the number of linear transmission components 50 is less than the number of wire bundles 34. Alternatively, the number of linear transmission components 50 may be the same as or greater than the number of wire bundles 34. Here, the linear transmission components 50 are located outermost along the parallel arrangement of the plurality of wire bundles 34. The linear transmission components 50 are located outside the plurality of wire bundles 34. Alternatively, the linear transmission components 50 may be located between the plurality of wire bundles 34.

[0097] The two linear transmission components 50 run parallel to one another along a portion of the path, then branch off in a branching region, extending in different directions. The linear transmission components 50 may also include linear transmission components that run parallel to one another throughout the entire base member 20. The linear transmission components 50 may also include linear transmission components that do not run parallel to one another throughout the entire base member 20. One end of each of the two linear transmission components 50 is connected to a connector C5 that is different from the connectors C3 and C4 connected to the electric wires 30. The other end of each of the two linear transmission components 50 is connected to connectors C1 and C2 connected to the electric wires 30. However, both the one end and the other end of the linear transmission components 50 may be connected to a connector that is different from the connector connected to the electric wires 30, or to the same connector.

[0098] The plurality of wires 30 include wires (hereinafter referred to as heterogeneous wires) having insulating coatings 32 formed of a material different from that of the material forming the arrangement surface 21. The resin material forming the insulating coatings 32 of the heterogeneous wires is different from the resin material forming the first layer 22 and the resin material forming the covering layer 52.

[0099] For example, the resin material constituting first layer 22 and the resin material constituting coating layer 52 are PVC, and the material constituting insulating coating portion 32 of the heterogeneous wire is a resin material different from PVC. In this case, the material constituting insulating coating portion 32 of the heterogeneous wire is not particularly limited as long as it is other than PVC. For example, it can be a polyolefin such as PE or PP, a silicone resin, or a fluororesin such as polytetrafluoroethylene.

[0100] The resin material can also be halogen-free. Halogen-free means that it contains no chlorine or bromine, or even if it does, it contains only trace amounts. For example, according to the IEC (International Electrotechnical Commission) standard, halogen-free is defined as a material containing chlorine and bromine at a content of 900 ppm or less for each, and 1500 ppm or less for the total content of chlorine and bromine. Halogen-free linear transmission components are also referred to as halogen-free wires (e.g., halogen-free wires in the case of electrical wires).

[0101] The combination of materials constituting the first layer 22, the insulating coating 32 of the different-type wire, and the covering layer 52 is not limited to the above. For example, the resin material constituting the first layer 22 and the resin material constituting the covering layer 52 may be PE, while the material constituting the insulating coating 32 of the different-type wire may be a resin material different from PE.

[0102] When the base member-side welding layer is welded to the cover member-side welding layer and the insulating coating 32 of the different-type wire under the same conditions, the welding strength between the base member-side welding layer and the cover member-side welding layer is stronger than the welding strength between the base member-side welding layer and the insulating coating 32 of the different-type wire. Because the resin material constituting the base member-side welding layer is of a different type than the resin material constituting the insulating coating 32 of the different-type wire, and of the same type as the resin material constituting the cover member-side welding layer, it is easy to make the welding strength between the base member-side welding layer and the cover member-side welding layer stronger than the welding strength between the base member-side welding layer and the insulating coating 32 of the different-type wire. The welding strength herein can be evaluated using, for example, the results of separate tests using the same type of peel test (e.g., the tests specified in JIS K6854).

[0103] The means for achieving the aforementioned welded state is not particularly limited. For example, various welding methods can be employed, such as ultrasonic welding, heat and pressure welding, hot air welding, and high-frequency welding. Furthermore, if the welded state is achieved using these methods, the base member 20, the cover member 40, and the linear transmission member 50 are welded and fixed by this method. Specifically, for example, when the base member 20, the cover member 40, and the linear transmission member 50 are welded together using ultrasonic welding, the fixing portion FP and the welded portion WP become ultrasonic welds.

[0104] In each strip-shaped sheet 42, as Figure 4 As shown, when viewing the wiring member 10 along the extension direction, a portion of the cover member-side welding layer along the extension direction of the wires 30 is welded to the base member-side welding layer. In other words, each strip-shaped sheet 42 is not entirely welded to the base member along the extension direction of the wires 30. Each strip-shaped sheet 42 has a portion along the extension direction of the wires 30 that is not welded to the base member-side welding layer.

[0105] <Effects of Embodiment 1, etc.>

[0106] According to the wiring component 10 configured as described above, the plurality of wires 30 extend as a large bundle portion 36 in the non-base component placement section, and extend as a plurality of wire bundles 34 in the base component placement section. Therefore, the height dimension of the wiring component 10 can be suppressed in the base component placement section. For example, Figure 3As shown, the height dimension of the portion where the plurality of wire bundles 34A, 34B, and 34C are arranged can be made smaller than the height dimension of the large bundle portion 36 in which these bundles are bundled. Furthermore, since the cover member 40 is fixed to the arrangement surface 21 at both sides of the plurality of wire bundles 34 and at positions between them, the linear transmission components of the wire bundles 34 are prevented from becoming intertwined and the height dimension of the wiring member 10 becoming undesirably high. Consequently, in the wiring member 10 formed by arranging the wire bundles 34 on the base member 20, the height dimension on the base member 20 can be reduced.

[0107] Furthermore, in the transition region between the plurality of fixing portions FP spaced apart along the extending direction of the wire bundle 34, some of the wires 30 change bundles 34. This eliminates the need to set a specific bundle 34 for each path when the wires 34 are separated from the large bundle portion 36. This facilitates appropriate setting of the number of wire bundles 34 and the thickness of each bundle 34. For example, the thickness of multiple wire bundles 34 can be made uniform in a certain section, or the thickness of a specific bundle 34 can be changed to suit the space in the vehicle.

[0108] In addition, in one transition region, two or more electric wires 30 change the electric wire bundle 34 to which they belong. This can prevent the transition region from being widely dispersed on the base member 20.

[0109] The cover member 40 is fixed to the base member 20 at positions on both sides of the bent portion 38. This prevents the wires 30 from being displaced from the base member 20 along the extending direction of the wires 30 when the wires 30 are pulled outward from the base member 20.

[0110] In addition, the base member 20 and the cover member 40 are welded and fixed. Therefore, in the wiring member 10, the member for fixing the cover member 40 and the base member 20 can be omitted.

[0111] Furthermore, the plurality of electric wires 30 include a linear transmission member having an insulating coating 32 formed of a material different from that constituting the arrangement surface 21. Thus, the linear transmission member, which is difficult to be directly welded to the arrangement surface 21, is held in the base member arrangement section by the cover member 40.

[0112] Furthermore, the coating layer of the linear transmission member 50 is welded to the placement surface 21. Thus, the linear transmission member 50 is directly fixed to the base member 20 without intervening any other fixing member.

[0113] Furthermore, the plurality of strip-shaped sheets 42 are fixed to the base member 20 at positions on both sides of and between the plurality of wire bundles 34. Thus, the cover member 40 does not need to be provided on the entire base member 20.

[0114] Furthermore, the plurality of wire bundles 34 extend outward from the plurality of end portions 20a, 20b, and 20c of the base member 20. This facilitates maintaining the wires 30 divided into the plurality of wire bundles 34 on the base member 20.

[0115] [Modification]

[0116] Figure 5 It is a plan view showing a modified example of the wiring member 10 .

[0117] In the wiring member 110 according to the modified example, the base member 20 is provided with an excess length absorbing portion for absorbing excess length of the wires 30. The excess length absorbing portion absorbs excess length caused by, for example, tolerances of the wires 30. The excess lengths of the multiple wires 30 constituting a single wire bundle 34 may differ. In this case, the amount of excess length absorbed by the excess length absorbing portion may differ between the wires 30 constituting the same wire bundle 34.

[0118] The excess length absorbing portion includes a detour portion 35. The detour portion 35 is provided between two fixing portions FP. One of the two fixing portions FP is designated as the first fixing portion FP, and the other as the second fixing portion FP. The detour portion 35 is the portion where the path of the electric wire 30 between the first and second fixing portions FP extends along a detour that is longer than the shortest path. Here, the detour portions 35 are provided on the electric wires 30E, 30F, and 30G. In the electric wires 30E and 30F, the detour portions 35 are provided at the bend 38.

[0119] Figure 6 This is a conceptual diagram of the detour portion 35 at the curved portion 38 .

[0120] exist Figure 6 In the figure, the fixing portions FP3 and FP4 provided on either side of the curved portion 38 are the first and second fixing portions. Line segment L1 connects the fixing portions FP3 and FP4. Intersection point P is the intersection of a straight line extending from the fixing portion FP3 along the previous extension direction and a straight line extending from the fixing portion FP4 along the previous extension direction. Line segment L2 connects the fixing portion FP3 and intersection point P. Line segment L3 connects the fixing portion FP4 and intersection point P. These three line segments are the three sides of triangle T.

[0121] The path of the electric wire 30 when it extends along the line segment L1 between the fixing portions FP3 and FP4 is the shortest path. The electric wire 30 extends along a path that protrudes outward from the line segment L1, thereby forming the path of the electric wire 30 as the detour path portion 35. The path of the electric wire 30 may not protrude outward from the path along the line segments L2 and L3. The path of the electric wire 30 may also be within the triangle T. The path of the electric wire 30 may also protrude outward from the path along the line segments L2 and L3, forming the detour path portion 35. The path of the electric wire 30 may also protrude outward from the triangle T.

[0122] Return to Figure 5 In the case where the detour path portion 35 is provided on the straight portion, the paths along the line segments L2 and L3 in the above example are identical to the path along the line segment L1. Figure 5 As shown, the electric wire 30G meanders between the first fixing portion FP and the second fixing portion FP. Here, the electric wire 30G meanders between the first fixing portion FP and the second fixing portion FP with a single peak (or valley). Alternatively, the electric wire 30G may meander between the first fixing portion FP and the second fixing portion FP with multiple peaks (or valleys).

[0123] The excess length absorbing portion is not necessarily the detour portion 35. The excess length absorbing portion may also include, for example, a twisted portion. The twisted portion is a portion formed by twisting the wires 30 constituting the wire bundle 34. At the portion of the wire bundle 34 where the twisted portion is formed, the wires 30 are spirally extended to absorb the excess length. Alternatively, at the portion where the twisted portion is formed, all the wires 30 constituting the wire bundle 34 are spirally extended. At the portion where the twisted portion is formed, it is not necessary for all the wires 30 constituting the wire bundle 34 to be spirally extended; it is sufficient for a portion of the wires 30 to be spirally extended. For example, when there is a wire 30 in the wire bundle 34 where the twisted portion is formed that does not require the excess length to be absorbed, the wire 30 may not be twisted. That is, in one wire bundle 34, the wire 30 that requires the excess length to be absorbed may be wound around the wire 30 that does not require the excess length to be absorbed and formed into a twisted portion.

[0124] Alternatively, both the detour portion 35 and the twisted portion may be provided in one bundle of wires 34. Alternatively, both the detour portion 35 and the twisted portion may be provided between a group of first fixing portions FP and second fixing portions FP. For example, in a case where the path of the bundle of wires 34 between two fixing portions FP is not the shortest path and a twisted portion is formed in the bundle of wires 34 between the two fixing portions FP, it can be considered that both the detour portion 35 and the twisted portion are provided between the two fixing portions FP. Alternatively, the detour portion 35 may be provided between one group of first fixing portions FP and second fixing portions FP, and the twisted portion may be provided between the other groups of first fixing portions FP and second fixing portions FP. Alternatively, the detour portion 35 may be provided in one bundle of wires 34, and the twisted portion may be provided in the other bundles of wires 34.

[0125] exist Figure 5 In the example shown, the detour path portion 35 is provided in the branch area. The detour path portion 35 does not need to be provided in the branch area and can be provided at any position. Figure 5 In the illustrated example, the bypass path portions 35 are provided for the plurality of electric wires 30E, 30F, and 30G. The bypass path portions 35 do not need to be provided for the plurality of electric wires 30; the bypass path portion 35 may be provided for only one electric wire 30. The bypass path portions 35 provided for the plurality of electric wires 30 are provided between a set of first and second fixing portions FP. The bypass path portions 35 provided for the plurality of electric wires 30 do not need to be provided between a set of first and second fixing portions FP; they may be provided dispersedly between a plurality of sets of first and second fixing portions FP.

[0126] In wiring member 110, cover member 40 includes cover portion 44. Cover portion 44 covers bypass path portion 35. Cover portion 44 is a separate component from strip-shaped sheet 42. Cover portion 44 also covers the two strip-shaped sheets 42 between which bypass path portion 35 is disposed. The material, rigidity, and other characteristics of cover portion 44 can be arbitrary. For example, cover portion 44 can be formed from base member 20, which has higher rigidity than strip-shaped sheet 42.

[0127] Here, the cover portion 44 covers the branch region and is formed in a shape corresponding to the branch portion of the base member 20 .

[0128] The cover portion 44 is fixed to the base member 20. Here, the cover portion 44 is fixed to the base member 20 at a position on the side edge of the base member 20. The fixing portion FP5 of the cover portion 44 and the base member 20 extends along the side edge of the base member 20. Here, the cover portion 44 is not fixed to the strip-shaped sheet 42. The cover portion 44 and the base member 20 may also be fixed to the strip-shaped sheet 42. The cover portion 44 and the base member 20 are not fixed at the middle portion in the width direction of the base member 20. The cover portion 44 and the base member 20 may also be fixed at the middle portion in the width direction of the base member 20. The cover portion 44 and the base member 20 are not fixed between the plurality of parallel wire bundles 34. The cover portion 44 and the base member 20 may also be fixed between the plurality of parallel wire bundles 34. In this case, the strip-shaped sheet 42 may also be omitted.

[0129] The cover portion 44 and the base member 20 may be secured by any method, for example, any of the methods described above for securing the strip-shaped sheet 42 and the base member 20. The securing method of the cover portion 44 and the base member 20 may be the same as or different from the securing method of the strip-shaped sheet 42 and the base member 20. Here, the cover portion 44 and the base member 20 are welded.

[0130] According to the wiring member 110, the base member 20 is provided with an excess length absorbing portion that absorbs excess length of the wires 30E, 30F, and 30G. This allows the base member 20 to absorb tolerances in the wires 30E, 30F, and 30G. Furthermore, the excess length absorbing portion includes a detour portion 35 that extends the path of the wires 30 between the first fixing portion FP3 and the second fixing portion FP4 along a longer path than the shortest path. This allows for simple installation of the excess length absorbing portion. Furthermore, the detour portion 35 is covered by the cover portion 44, thereby preventing excess length of the wires 30E, 30F, and 30G from protruding outward.

[0131] Figure 7 It is a plan view showing another modified example of the wiring member 10 . Figure 8 It is along Figure 7 A cross-sectional view obtained by cutting along line VIII-VIII of .

[0132] In the wiring member 210 according to the modified example, the wire bundle 34 includes a tape portion 39. The tape portion 39 is a portion wrapped with adhesive tape TA. In contrast to the wiring member 10 of the first embodiment, the wire bundle 34 is not bound with adhesive tape TA. In contrast, in the wiring member 210 of this example, the wire bundle 34 is bound with adhesive tape TA. The cover member 40 is secured to the base member 20 at a position lateral to the portion covering the tape portion 39. This prevents the wire bundle from becoming untied at the tape portion 39, and prevents the wires 30 from becoming caught between the cover member 40 and the base member 20 when the cover member 40 is secured to the base member 20.

[0133] Here, a plurality of belt-wrap portions 39 are provided at intervals along the direction in which the wire harness 34 extends. Alternatively, the belt-wrap portions 39 may be provided continuously throughout the entire wire harness 34 in the direction in which the wire harness 34 extends. Another belt-shaped sheet 42 is placed over each belt-wrap portion 39. Alternatively, a single cover member 40 may cover the plurality of belt-wrap portions 39 spaced apart along the direction in which the wire harness 34 extends. Each belt-shaped sheet 42 is secured to the base member 20.

[0134] In the wire harness 34, the portion where the tape wrap 39 is provided may correspond to the portion covered with the tape sheet 42. That is, the tape sheet 42 may be completely covered up to the portion where the tape wrap 39 is provided, and the tape wrap 39 may be completely provided in the portion covered with the tape sheet 42.

[0135] In the wire harness 34, the portion where the tape wrap 39 is provided does not necessarily correspond to the portion covered with the strip-shaped sheet 42. In the portion where the tape wrap 39 is provided, there may also be a portion not covered with the strip-shaped sheet 42. For example, when the number of wires 30 in the wire harness 34 is large, the tape wrap 39 may be provided between the strip-shaped sheets 42. This makes it difficult for the multiple wires 30 that form a wire harness 34 between the strip-shaped sheets 42 to become untied. Furthermore, for example, the tape wrap 39 may be provided at the bend 38. This makes it difficult for the multiple wires 30 that form a wire harness 34 to become untied at the bend 38.

[0136] The portion covered with the strip-shaped sheet 42 may also include a portion where the tape wrapping portion 39 is not provided. For example, when the number of wires 30 in the wire bundle 34 is small, the portion covered with the strip-shaped sheet 42 may not include the tape wrapping portion 39. This simplifies the tape wrapping operation. In addition, for example, when a branch line is formed from a main line portion, the number of wires 30 constituting one wire bundle 34 at the main line portion may be greater than the number of wires 30 constituting one wire bundle 34 at the branch line portion. In this case, the tape wrapping portion 39 may be provided on the wire bundle 34 at the main line portion, and not provided on the branch line portion.

[0137] exist Figure 8 In the example shown, the cross-sectional shape of the wound belt portion 39 is formed into a circular shape. The cross-sectional shape of the wound belt portion 39 may also be formed into a flat shape.

[0138] Alternatively, the plurality of wires 30 may include wires that are less likely to fuse to the arrangement surface 21 than the linear transmission member 50 (hereinafter referred to as refractory wires). In addition to the aforementioned heterogeneous wires, refractory wires may also include twisted wires. Twisted wires are formed by twisting a pair of sheathed wires that transmit differential signals.

[0139] Specifically, if the twisted wire is arranged in the base component arrangement interval, the transverse arrangement portion and the longitudinal arrangement portion are alternately continuous along the extension direction of the twisted wire. The transverse arrangement portion is a portion where the two covered wires are arranged in a direction parallel to the arrangement surface 21. The longitudinal arrangement portion is a portion where the two covered wires are arranged in the normal direction of the arrangement surface 21. At the twisted wire, in order not to reduce the noise suppression effect, it is preferable that the transverse arrangement portion and the longitudinal arrangement portion are as scattered as possible. When the wire is welded to the arrangement surface 21, stamping is sometimes performed together with heating. At this time, when the twisted wire is stamped, it is sometimes difficult to set the conditions for obtaining good welding strength without causing the transverse arrangement portion and the longitudinal arrangement portion to be scattered. Therefore, the twisted wire is more difficult to weld to the base component 20 than the single-core wire.

[0140] The configurations of the three wire harnesses 34A, 34B, and 34C, the two wire harnesses 34D and 34E, and the two wire harnesses 34F and 34G in the non-base component placement area are not limited to those described above and can be modified as appropriate or combined as desired. For example, the two wire harnesses 34D and 34E can be formed as a large bundle in the non-base component placement area.

[0141] Furthermore, when multiple non-base component placement sections are provided as in the wiring member 10 of the first embodiment, the large bundle portion 36 may be provided in at least one of the multiple non-base component placement sections. Furthermore, among the multiple wires 30 constituting the wire bundle 34 in the base component placement section, some wires 30 may not be provided with the large bundle portion 36. At least a portion of the multiple wires 30 constituting the wire bundle 34 in the base component placement section may be provided with the large bundle portion 36 in one of the at least one non-base component placement section. In the wiring member 10 of the first embodiment, the wires 30D constituting the wire bundles 34D and 34F in the base component placement section are not provided with the large bundle portion 36 in the non-base component placement section. Alternatively, all of the multiple wires 30 constituting the wire bundle 34 in the base component placement section may be provided with the large bundle portion 36 in one of the at least one non-base component placement section.

[0142] In the above example, the transition region and the bypass path portion 35 are provided together in the branch region, but this is not a necessary structure. The transition region and the bypass path portion 35 may also be provided between different fixed portions FP. For example, one of the transition region and the bypass path portion 35 may be provided in the branch region, and the other may be provided in the curved portion 38. In addition, even if the transition region and the bypass path portion 35 are provided between the same fixed portions FP, the fixed portions FP may be between fixed portions FP other than the branch region. For example, the transition region and the bypass path portion 35 may be provided together in the curved portion 38. That is, the excess length absorption portion provided between specific fixed portions FP, such as the bypass path portion 35, may be provided between the same fixed portions FP as the transition region. In this case, the position of the fixed portions FP is not particularly limited and may be between any fixed portions FP, such as the branch region, the curved portion 38, or the straight portion. In addition, the excess length absorption portion between specific fixed portions FP, such as the bypass path portion 35, may be provided between first fixed portions FP, and the transition region may be provided between second fixed portions FP, which is different from the first fixed portions FP. In this case, the positions between the first fixing portions FP and the positions between the second fixing portions FP may be different from each other, and the respective positions may be between any fixing portions FP such as the branch region, the curved portion 38 , or the straight portion.

[0143] This positional relationship between the excess length absorbing portion and the transition region can be applied to both cases where an excess length absorbing portion, such as the detour path portion 35, is provided on the wires 30 constituting a transition pair, and cases where the detour path portion 35 is provided on a wire 30 different from the wires 30 constituting a transition pair. Specifically, the transition region of the wires 30 constituting a transition pair and the excess length absorbing portion provided on that wire 30 can be located between the same fixing portion FP or between different fixing portions FP. Furthermore, the transition region of the wires 30 constituting a transition pair and the excess length absorbing portion provided on a wire different from that wire 30 can be located between the same fixing portion FP or between different fixing portions FP.

[0144] In the above example, the first linear transmission component covered by the cover member 40 is described as the electric wire 30, but this is not a required configuration. The first linear transmission component, like the linear transmission component 50 serving as the second linear transmission component, may be a linear transmission component that transmits electricity or light. In the above example, the entire wire bundle 34 consists solely of the electric wires 30, but this is not a required configuration. For example, at least one of the wire bundles 34 may include a linear transmission component that transmits light (e.g., an optical fiber cable). Furthermore, for example, a linear transmission component bundle consisting solely of linear transmission components that transmit light may be employed in place of the at least one wire bundle 34.

[0145] Furthermore, the configurations described in the above-mentioned embodiments and modifications can be appropriately combined as long as they do not contradict each other.
