[0019] [Description of Embodiments of the Present Disclosure]

[0020] First, embodiments of the present disclosure will be described by way of examples.

[0021] The wiring member of the present disclosure is as follows.

[0022] (1) A wiring member, comprising: a sheet; a first linear transmission member fixed to the sheet; and a second linear transmission member, the rigidity of the second linear transmission member being lower than that of the first linear transmission member, the second linear transmission member being fixed to the sheet, the intersection between the first linear transmission member and the second linear transmission member being provided on the sheet, and the first linear transmission member being located closer to the sheet than the second linear transmission member in the intersection. The first linear transmission member having a higher rigidity than the second linear transmission member is located on the sheet side in the intersection. Therefore, the first linear transmission member can be fixed to the sheet continuously or at a small fixed interval in the section including the intersection. Thus, in the section including the intersection, the first linear transmission member is difficult to fall off from the sheet.

[0023] (2) In the wiring member of (1), the first linear transmission member may be any one of a power line, a ground line, a shielded line, and a multi-core line, and the second linear transmission member may be a single-core signal line. Thus, the first linear transmission member, which is any one of a power line, a ground line, a shielded line, and a multi-core line, is unlikely to fall off the sheet.

[0024] (3) In the wiring member of (1) or (2), the first linear conveying member may intersect the plurality of second linear conveying members in a parallel path portion where the plurality of second linear conveying members are parallel. Thus, the plurality of second linear conveying members can suppress the first linear conveying member from floating from the sheet.

[0025] (4) In any one of the wiring members of (1) to (3), the coating layers of the first and second linear transmission members may be fused to the sheet material, thereby easily fixing the first and second linear transmission members to the sheet material.

[0026] [Details of the embodiments of the present disclosure]

[0027] Hereinafter, specific examples of the wiring member of the present disclosure will be described with reference to the drawings. It should be noted that the present disclosure is not limited to these examples, but is indicated by the claims, and is intended to include all changes within the meaning and scope equivalent to the claims.

[0028] [Implementation Method 1]

[0029] Hereinafter, the wiring member according to the first embodiment will be described. Figure 1 It is a schematic plan view showing the wiring member 10 according to the first embodiment. Figure 2 yes Figure 1 A partial enlarged view of . Figure 3 yes Figure 2 A cross-sectional view taken along line III-III. Figure 2 and Figure 3 In FIG. 1 , the portion indicated by the imaginary line is the fixing portion FP.

[0030] The wiring member 10 includes a sheet 20 and a plurality of linear conveying members 30. The plurality of linear conveying members 30 are fixed to the sheet 20. The sheet 20 is formed in a flat shape as a whole. The wiring member 10 is maintained in a flat state by fixing the plurality of linear conveying members 30 to the sheet 20.

[0031] The sheet 20 may be any material, structure, etc. as long as it can fix the plurality of linear conveying members 30. As for the material constituting the sheet 20, the sheet 20 is formed of a resin material. The material constituting the sheet 20 may also be a material other than resin, such as a metal or an inorganic substance. As for the structure of the sheet 20, the sheet 20 has a double-layer structure. The structure of the sheet 20 may be a single-layer structure or a multi-layer structure of three or more layers.

[0032] The sheet 20 includes a first layer 22 and a second layer 24. The first layer 22 is a welding layer. The linear conveying member 30 is welded and fixed in the welding layer. The welding layer includes a resin material, preferably a thermoplastic resin material. The resin material of the welding layer softens and welds to the welding partner. The type of the above-mentioned resin material is not particularly limited, and polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), etc. can be used.

[0033] The structure of the welding layer is not particularly limited. For example, the welding layer may be a sheet having a uniform solid cross section (also referred to as a non-foamed sheet or a solid sheet, etc.). Moreover, for example, the welding layer may also be a foamed sheet, etc. Moreover, for example, the welding layer may also be a fiber material sheet such as a woven cloth, a woven cloth or a non-woven cloth. One surface of the first layer 22 is set as one main surface of the sheet 20.

[0034] The second layer 24 is formed of a material different from that of the welding layer or has a different structure. The second layer 24 enhances the function of the welding layer or adds a function that the welding layer does not have to the sheet 20. In addition to the materials described in the welding layer, the material constituting the second layer 24 may also be a metal, an inorganic substance, etc. The structure of the second layer 24 may also be any of the structures described in the welding layer. One surface of the second layer 24 is set as the other main surface of the sheet 20.

[0035] The other surface of the first layer 22 contacts the other surface of the second layer 24, and the first layer 22 and the second layer 24 are fixed. The fixing form of the first layer 22 and the second layer 24 is not particularly limited, but can be fixed by welding or bonding. For example, when at least one of the first layer 22 and the second layer 24 is a sheet with gaps on the surface such as a fiber material sheet or a foam sheet, the resin material or the adhesive can enter the gap and be fixed. Thus, the so-called anchoring effect is exerted, and the first layer 22 and the second layer 24 are firmly fixed.

[0036] Here, the case where the first layer 22 is a solid sheet made of resin and the second layer 24 is a fiber material sheet is described. Here, the case where the first layer 22 and the second layer 24 are fused is described. That is, the resin of the first layer 22 enters between the fibers of the second layer 24 in a fluid state and then solidifies. In this way, the resin of the first layer 22 is maintained in the state of entering between the fibers of the second layer 24, and the first layer 22 and the second layer 24 are firmly fixed.

[0037] The first layer 22 and the second layer 24 are formed to be the same size (same planar shape). The first layer 22 and the second layer 24 may be formed so that one is larger than the other. The contact area of ​​the first layer 22 and the second layer 24 is fixed as a whole. The first layer 22 and the second layer 24 may be fixed only in a part of the contact area.

[0038] The sheet 20 may also be a soft member. For example, the first layer 22 is a solid sheet made of a soft resin such as soft PVC, the second layer 24 is a nonwoven fabric made of PET, and the sheet 20 is a soft member. For example, the sheet 20 may have flexibility that can follow the bending of the linear transmission member 30. The wiring member 10 may also be configured to be able to bend in the thickness direction (bend such that the fold is along the main surface of the sheet 20).

[0039] The plurality of linear transmission members 30 are linear members that transmit electricity or light, etc. The plurality of linear transmission members 30 can be conceived as members that connect components in a vehicle to each other. A connector C, for example, is provided at the end of the linear transmission member 30. The linear transmission member 30 is connected to the counterpart component by connecting the connector C to a connector provided on the counterpart component. That is, the wiring member 10 is used in a vehicle, etc. as a wiring member 10 that electrically (or optically) connects various components to each other. The connector C can also be fixed to the sheet 20.

[0040] The paths of the plurality of linear conveying members 30 are set according to the positions of the components that are the connection destinations, etc. By fixing the plurality of linear conveying members 30 to the sheet 20, the plurality of linear conveying members 30 are maintained in a state along the wiring paths corresponding to the positions of the components that are the respective connection destinations, etc. The paths of the plurality of linear conveying members 30 may also be constituted by a combination of a straight path and a curved path. The sheet 20 may also be constituted by a combination of a straight path and a curved path. The plurality of linear conveying members 30 may also be fixed to the sheet 20 in the form of branch lines branching from the main line. The sheet 20 may also be formed in the shape of a portion in which a fixed branch line is branched from a portion in which the main line is fixed. Here, the plurality of linear conveying members 30 are bent on the sheet 20. Moreover, the plurality of linear conveying members 30 are branched on the sheet 20.

[0041] The linear transmission member 30 includes a transmission line body 31 and a coating 32. The transmission line body 31 is a transmission path for transmitting electric power or light. For example, when the linear transmission member 30 is an electric wire, the transmission line body 31 is a conductor core wire. The conductor core wire is composed of one or more wires. The wire is formed of copper, copper alloy, aluminum, aluminum alloy, etc. Moreover, when the linear transmission member 30 is an optical fiber, the transmission line body 31 is a core and a coating. The coating 32 is a layer covering the transmission line body 31. The resin material constituting the coating 32 is not particularly limited and can be set appropriately. For example, the linear transmission member 30 can also be a general electric wire having a core wire and a coating around the core wire, or can be a shielded wire, a twisted wire, an enameled wire, a nickel-chromium alloy wire, an optical fiber, etc.

[0042] The power transmission linear transmission member 30 may be various signal lines or various power lines. A part of the power transmission linear transmission member 30 may be used as an antenna or a coil for transmitting or receiving signals or power to or from space.

[0043] In addition, the linear transmission member 30 may also be a single-core wire. A single-core wire is a single linear object. A single-core wire is a linear transmission member 30 with one transmission path. The linear transmission member 30 may also be a multi-core wire. A multi-core wire is a composite of multiple linear objects. A single-core wire is a linear transmission member 30 with multiple transmission paths. The multi-core wire may also be, for example, a twisted wire, a cable in which multiple linear objects are gathered and covered with a sheath 36, etc.

[0044] Here, the linear transmission member 30 is fixed to the sheet 20 by welding. In this case, the outermost layer of the linear transmission member 30 is welded to the welding layer. The outermost layer in the linear transmission member 30 is the coating layer 32. The coating layer 32 is a material that can be welded to the welding layer. The resin material constituting the coating layer 32 is the same type as the resin material constituting the welding layer. For example, the resin material constituting the welding layer and the resin material constituting the coating layer 32 are PVC or polyolefin. However, the fixing form of the linear transmission member 30 and the sheet 20 is not limited to welding. The fixing forms other than welding will be described in detail in the modified examples described later.

[0045] In addition, here, the fixing parts FP of the sheet 20 and the linear conveying member 30 are arranged at intervals along the direction in which the linear conveying member 30 extends. The intervals of the fixing parts FP are not particularly limited and can be set appropriately. However, the fixing parts FP of the sheet 20 and the linear conveying member 30 can also be continuously arranged along the direction in which the linear conveying member 30 extends.

[0046] Here, the linear conveying members 30 include eight. The eight linear conveying members 30 are divided into two linear conveying members 30A, two linear conveying members 30B, and four linear conveying members 30C. The two linear conveying members 30A intersect with the two linear conveying members 30B in the first intersection area A1, respectively. The two linear conveying members 30A and the two linear conveying members 30B intersect with the four linear conveying members 30C in the second intersection area A2, respectively. The first intersection area A1 and the second intersection area A2 are provided at positions separated along the extension direction of the linear conveying members 30A. Only one of the first intersection area A1 and the second intersection area A2 may be provided.

[0047] In this specification, the portion where two linear conveying members 30 on the sheet 20 intersect is referred to as the intersection 40. Hereinafter, the portion where two linear conveying members 30A and 30B intersect is referred to as the intersection 40AB. The portion where two linear conveying members 30A and 30C intersect is referred to as the intersection 40AC. The portion where two linear conveying members 30B and 30C intersect is referred to as the intersection 40BC.

[0048] There are two or more types of linear transmission members having different rigidities among the plurality of linear transmission members 30. In the combination of two linear transmission members having different rigidities, the linear transmission member having higher rigidity is set as the first linear transmission member, and the linear transmission member having lower rigidity is set as the second linear transmission member. The rigidity of the two linear transmission members 30 can also be determined by the amount of bending when a predetermined load is applied to a predetermined position while a test piece having a predetermined length is supported in a predetermined posture, for example.

[0049] The rigidity of the linear transmission member 30 is determined by combining a plurality of conditions such as the layer structure of the linear transmission member 30 , the material and structure of the transmission line body 31 , and the material and structure of the coating layer 32 .

[0050] For example, in two linear transmission members 30, a single-core general electric wire and a single-core shielded wire, the conditions other than the layer structure are the same. In this case, generally, the rigidity of the single-core shielded wire is easier to increase than the rigidity of the single-core general electric wire. It should be noted that the single-core general electric wire is, for example, an electric wire composed of a conductor core wire and a coating layer. The single-core shielded wire is, for example, an electric wire in which a shielding layer and a second coating layer are further provided in addition to the single-core general electric wire.

[0051] In addition, for example, in the two linear transmission members 30, the single-core general electric wire and the multi-core wire, the conditions other than the number of cores are the same. That is, the multi-core wire is a composite of a plurality of single-core general electric wires. In this case, generally, the rigidity of the multi-core wire is easier to increase than the rigidity of the single-core general electric wire.

[0052] In addition, for example, in two linear transmission members 30 having different conductor cross-sectional areas, conditions other than the conductor cross-sectional area are the same. In this case, generally, the rigidity of the linear transmission member 30 having a larger conductor cross-sectional area is easier to increase than the rigidity of the linear transmission member 30 having a smaller conductor cross-sectional area. Here, in the case where the power line, the ground line, and the signal line are composed of a single-core general electric wire, generally, the conductor cross-sectional area of ​​the power line and the ground line is easier to become larger than the conductor cross-sectional area of ​​the signal line. Therefore, the rigidity of the power line and the ground line is easier to increase than the rigidity of the signal line. This is because the power line and the ground line are sometimes used in circuits for supplying power to actuators, etc., and in order to allow a large current to flow in such circuits, it is necessary to increase the conductor cross-sectional area.

[0053] For example, in two linear transmission members 30, one of which is made of copper and the other is made of aluminum, the conditions other than the material of the transmission wire body 31 are the same. In this case, the rigidity of the aluminum wire is generally higher than that of the copper wire.

[0054] In addition, for example, in two linear transmission members 30 having the same conductor cross-sectional area and different numbers of wires of the transmission line body 31, conditions other than the number of wires of the transmission line body 31 are the same. In this case, generally, the rigidity of the linear transmission member 30 having a smaller number of wires is more likely to be higher than the rigidity of the linear transmission member 30 having a larger number of wires.

[0055] Sometimes, one of the two linear conveying members 30 constituting an intersection 40, which is located on the sheet 20 side, is referred to as a lower linear conveying member, and the other linear conveying member 30 is referred to as an upper linear conveying member. When focusing on the rigidity of the lower linear conveying member and the upper linear conveying member constituting the intersection 40, the intersection 40 is divided into three, namely, a first intersection, a second intersection, and a third intersection. The first intersection is an intersection where the rigidity of the lower linear conveying member is higher than that of the upper linear conveying member. The second intersection is an intersection where the rigidity of the upper linear conveying member is higher than that of the lower linear conveying member. The third intersection is an intersection where the rigidity of the lower linear conveying member is the same as that of the upper linear conveying member.

[0056] exist Figure 2 In the example shown, all four intersections 40 in the first intersection region A1 are intersections 40AB. In the first intersection region A1, the linear conveying members 30A and B intersect to change the arrangement order. The linear conveying members 30A and B are parallel to both sides of the first intersection region A1.

[0057] The linear conveying member 30A has higher rigidity than the linear conveying member 30B. Therefore, in the combination of the linear conveying members 30A and 30B, the linear conveying member 30A is the first linear conveying member, and the linear conveying member 30B is the second linear conveying member. Furthermore, in the intersection 40AB, the linear conveying member 30A is the lower linear conveying member located on the sheet 20 side, and the linear conveying member 30B is the upper linear conveying member. Therefore, the intersection 40AB is all the first intersection.

[0058] It should be noted that the linear conveying member 30A extends linearly in the section including the intersection 40AB. The linear conveying member 30B extends in a curved manner in the section including the intersection 40AB. In the section including the intersection 40AB between the parallel path sections, the path of the linear conveying member 30A is shorter than the path of the linear conveying member 30B. In this way, in the section including the intersection 40 where the arrangement order of the two linear conveying members 30 is changed, the path of the second linear conveying member can be configured to be longer than the path of the first linear conveying member.

[0059] exist Figure 2In the example shown, 8 of the 16 intersections 40 of the second intersection area A2 are intersections 40AC, and 8 are intersections 40BC. In the second intersection area A2, the linear conveying members 30A, 30B, and 30C intersect for branching. The linear conveying members 30A, 30B, and 30C are parallel to the second intersection area A2 on one side. The linear conveying members 30A, 30B, and the linear conveying member 30C extend in different directions on the other side relative to the second intersection area A2. It should be noted that the linear conveying members 30A, 30B, and the linear conveying member 30C may also extend in different directions on one side relative to the second intersection area A2.

[0060] The linear conveying member 30A has higher rigidity than the linear conveying member 30C. Therefore, in the combination of the linear conveying members 30A and 30C, the linear conveying member 30A is the first linear conveying member, and the linear conveying member 30C is the second linear conveying member. In the intersection 40AC, the linear conveying member 30A is the lower linear conveying member located on the sheet 20 side, and the linear conveying member 30C is the upper linear conveying member. Therefore, the intersection 40AC is all the first intersection.

[0061] The rigidity of the linear conveying member 30B is the same as the rigidity of the linear conveying member 30C. Therefore, the first linear conveying member and the second linear conveying member do not exist in the combination of the linear conveying members 30B and 30C. Moreover, all the intersections 40BC are third intersections. It should be noted that in the intersection 40BC, the linear conveying member 30B is the lower linear conveying member located on the sheet 20 side, and the linear conveying member 30C is the upper linear conveying member.

[0062] exist Figure 2 In the example shown, all of the multiple intersections 40AB and 40AC set in one linear conveying member 30A are first intersections. Among the multiple intersections 40AB and 40BC set in one linear conveying member 30B, a portion of the intersections 40AB are first intersections, and another portion of the intersections 40BC are third intersections. Similarly, among the multiple intersections 40AC and 40BC set in one linear conveying member 30C, a portion of the intersections 40AC are first intersections, and another portion of the intersections 40BC are third intersections. In this way, the multiple intersections of one linear conveying member 30 may include multiple of the first intersection, the second intersection, and the third intersection.

[0063] When the linear conveying member 30 constituting the first intersection constitutes the second intersection or the third intersection in another intersection 40 in the same intersection area, the linear conveying member 30 that becomes the upper linear conveying member in the first intersection may also be the upper linear conveying member in the second intersection or the third intersection. For example, the linear conveying member 30C constituting the first intersection in the intersection 40AC constitutes the third intersection in another intersection 40BC in the same intersection area. The linear conveying member 30C is also the upper linear conveying member in any intersection 40 of the intersections 40AC and BC. Similarly, when the linear conveying member 30 constituting the first intersection constitutes the second intersection or the third intersection in another intersection 40 in the same intersection area, the linear conveying member 30 that becomes the lower linear conveying member in the first intersection may also be the lower linear conveying member in the second intersection or the third intersection.

[0064] Alternatively, the first linear transmission member may be any one of a power line, a ground line, a shielded line, and a multi-core line, and the second linear transmission member may be a single-core signal line. Here, one of the two linear transmission members 30A is a power line, and the other is a ground line. The power line and the ground line are lines that supply power to the device. The power line is a positive-side wire. The ground line is a negative-side wire. The ground line is sometimes omitted by adopting main body grounding, etc. The remaining linear transmission members 30B and 30C are all single-core signal lines.

[0065] like Figure 2 As shown, a plurality of second linear conveying members are provided. The plurality of second linear conveying members are parallel in the parallel path portion. In the parallel path portion, the first linear conveying member intersects with the plurality of second linear conveying members. The plurality of second linear conveying members press the first linear conveying member. Specifically, in the second intersection area A2, four linear conveying members 30C are parallel. Furthermore, two linear conveying members 30A intersect with the four linear conveying members 30C, respectively. The two linear conveying members 30A are pressed by the four linear conveying members 30C, respectively.

[0066] <Effects of Implementation Method 1, etc.>

[0067] According to the wiring member 10 configured as described above, in the intersections 40AB and 40AC, the linear conveying member 30A having higher rigidity than the linear conveying members 30B and 30C is located on the sheet 20 side. Therefore, the linear conveying member 30A can be fixed to the sheet 20 continuously in the section including the intersections 40AB and 40AC, or fixed to the sheet 20 at a small fixed interval. As a result, in the section including the intersections 40AB and 40AC, the linear conveying member 30A is less likely to fall off from the sheet 20. Here, the linear conveying member 30A, which is a power line or a ground line, is less likely to fall off from the sheet 20.

[0068] Compared with the linear conveying members 30B and 30C having low rigidity, the linear conveying member 30A having high rigidity is difficult to follow the bending of the sheet 20 when the sheet 20 is bent, and is therefore easy to fall off the sheet 20. The upper linear conveying member of the two linear conveying members 30 forming the intersection 40 has a portion that floats from the sheet 20 in the section including the intersection 40 and cannot be fixed to the sheet 20. In contrast, the lower linear conveying member can contact and fix the sheet 20 in the section including the intersection 40. Therefore, the linear conveying member 30A having high rigidity becomes the lower linear conveying member, thereby being able to contact and fix the sheet 20 in the section including the intersections 40AB and AC, and thus being difficult to fall off the sheet 20.

[0069] In addition, since the linear conveying member 30A intersects the plurality of linear conveying members 30C in the parallel path portion, the linear conveying member 30A can be prevented from floating up from the sheet 20 by the plurality of linear conveying members 30C.

[0070] Furthermore, since the coating layer 32 of each of the linear conveying members 30 is fused to the sheet 20 , the linear conveying members 30 can be easily fixed to the sheet 20 .

[0071] [Modifications]

[0072] Figure 4 2 is a cross-sectional view showing a modified example of the wiring member 10. Figure 4 In the wiring member 110 shown, the linear transmission member 130A is a shielded wire. The linear transmission member 130A includes a transmission wire body 31, a first coating layer 32a, a shielding layer 33, and a second coating layer 32b. The transmission wire body 31, the first coating layer 32a, the shielding layer 33, and the second coating layer 32b are stacked in sequence from the inside to the outside. The transmission wire body 31 and the first coating layer 32a can adopt the same structure as the transmission wire body 31 and the coating layer 32 in the wiring member 10. The shielding layer 33 is not particularly limited. For example, the shielding layer 33 can also be a conductor foil. The conductor foil can be spirally wound or attached longitudinally. Moreover, for example, the shielding layer 33 can also be a braided wire. The braided wire can also be formed into a cylindrical shape. The second coating layer 32b in the linear transmission member 130A is set as the outermost layer. When the second coating layer 32b is fused to the welding layer, the second coating layer 32b can be a material that can be fused to the welding layer.

[0073] The linear conveying member 130A has higher rigidity than the linear conveying member 30C. Therefore, in the combination of the linear conveying members 130A and 30C, the linear conveying member 130A is the first linear conveying member, and the linear conveying member 30C is the second linear conveying member. In the intersection 140AC of the linear conveying member 130A and the linear conveying member 30C, the linear conveying member 130A is the lower linear conveying member, and the linear conveying member 30C is the upper linear conveying member. Therefore, the intersection 140AC is the first intersection. In this case, the linear conveying member 130A as a shielding wire is also difficult to fall off from the sheet 20.

[0074] Figure 5 2 is a cross-sectional view showing another modified example of the wiring member 10. Figure 5 In the wiring member 210 shown, the linear transmission member 230A is a multi-core wire. Figure 5 The linear transmission member 230A shown has two transmission paths. The linear transmission member may also be a multi-core wire having three or more transmission paths. The linear transmission member 230A includes two coated wires 35. The two coated wires 35 are covered by a sheath 36. Therefore, the linear transmission member 230A is a multi-core wire with a sheath 36.

[0075] The linear conveying member 230A has higher rigidity than the linear conveying member 30C. Therefore, in the combination of the linear conveying members 230A and 30C, the linear conveying member 230A is the first linear conveying member, and the linear conveying member 30C is the second linear conveying member. In the intersection 240AC of the linear conveying member 230A and the linear conveying member 30C, the linear conveying member 230A is the lower linear conveying member, and the linear conveying member 30C is the upper linear conveying member. Therefore, the intersection 240AC is the first intersection. Even in this case, the linear conveying member 230A as a multi-core wire is difficult to fall off from the sheet 20.

[0076] So far, the case where the linear conveying member 30 on the sheet 20 is the first linear conveying member or the second linear conveying member has been described, but this is not necessarily a structure. For example, a third linear conveying member that does not intersect with other linear conveying members 30 may be provided on the sheet 20. The third linear conveying member may extend on the sheet 20 in the same path as the first linear conveying member or the second linear conveying member. The third linear conveying member may extend on the sheet 20 in a different path from the first linear conveying member and the second linear conveying member.

[0077] In addition, the examples in which the wiring members 10, 110, and 210 do not include the second intersection portion have been described so far, but this is not a necessary structure. The wiring member may also include the second intersection portion. When there are multiple intersection portions 40 on the sheet 20, at least one intersection portion 40 only needs to be a first intersection portion.

[0078] In the example shown in Embodiment 1, one linear conveying member 30 intersects with different linear conveying members 30 at multiple locations. That is, multiple intersections 40 are set in one linear conveying member 30. However, only one intersection may be set in one linear conveying member.

[0079] In the example shown in Embodiment 1, the linear conveying member 30A and the plurality of linear conveying members 30C are intersected in the parallel path portion, but this is not an essential configuration. The linear conveying member 30A may intersect with one linear conveying member 30 .

[0080] In addition, the example shown in Embodiment 1 is an example in which two types of linear transmission members 30 having different rigidities are provided, but sometimes three or more types of linear transmission members 30 having different rigidities are provided in one wiring member 10. For example, it is conceivable that three types of linear transmission members are provided in order from the one having high rigidity, namely, a linear transmission member having high rigidity, a linear transmission member having medium rigidity, and a linear transmission member having low rigidity. In this case, in a combination of a linear transmission member having high rigidity and a linear transmission member having medium rigidity, the linear transmission member having high rigidity is the first linear transmission member, and the linear transmission member having medium rigidity is the second linear transmission member. Moreover, in a combination of a linear transmission member having high rigidity and a linear transmission member having low rigidity, the linear transmission member having high rigidity is the first linear transmission member, and the linear transmission member having low rigidity is the second linear transmission member. Moreover, in a combination of a linear transmission member having medium rigidity and a linear transmission member having low rigidity, the linear transmission member having medium rigidity is the first linear transmission member, and the linear transmission member having low rigidity is the second linear transmission member. Thus, the intermediate rigidity linear transmission member can be either the first linear transmission member or the second linear transmission member depending on the object with which it is combined. Therefore, the plurality of intersections in the intermediate rigidity linear transmission member can include the first intersection and the second intersection.

[0081] When three or more linear transmission members with different rigidities are provided in one wiring member, the linear transmission member with the highest rigidity among the linear transmission members constituting the intersection may be set as the lower wire portion in all the multiple intersections constituted by the linear transmission members. The linear transmission member with the lowest rigidity among the linear transmission members constituting the intersection may be set as the upper wire portion in all the multiple intersections constituted by the linear transmission members.

[0082] As described above, the fixing form of the sheet 20 and the linear transmission member 30 may be a welding fixation or a fixing form other than welding fixation. As the fixing form of the sheet 20 and the linear transmission member 30, it may be a contact part fixation or a non-contact part fixation, or both may be used. Here, the contact part fixation refers to the situation where the contact part of the sheet 20 and the linear transmission member 30 is adhered and fixed. Moreover, the non-contact part fixation is a fixing form other than the contact part fixation, for example, a suture, a cover, an adhesive tape, etc. is used to press the linear transmission member 30 toward the sheet 20 or the sheet 20 and the linear transmission member 30 are sandwiched and maintained in this state.

[0083] As the above-mentioned contact part fixing form, the contact part can be indirectly fixed, the contact part can be directly fixed, and both can be used in different areas. Here, the indirect contact part fixing refers to the case where the sheet 20 and the linear transmission member 30 are indirectly fixed by adhesion via an adhesive, a sticking agent, a double-sided adhesive tape, etc. provided therebetween. Moreover, the direct contact part fixing refers to the case where the sheet 20 and the linear transmission member 30 are directly fixed by adhesion without using an adhesive provided separately. In the direct contact part fixing, for example, the case where the sheet 20 and the linear transmission member 30 are fixed by adhesion by melting the resin contained in at least one of the sheet 20 and the linear transmission member 30 can be considered.

[0084] Whenever the above-mentioned state of directly fixing the contact parts is formed, the resin may be melted by heat or dissolved by a solvent. That is, the state of directly fixing the contact parts may be a state of directly fixing the contact parts by heat or a state of directly fixing the contact parts by a solvent. The state of directly fixing the contact parts by heat is preferred.

[0085] At this time, the method for forming a state in which the contact parts are directly fixed is not particularly limited, and a known method such as welding can be used. For example, in the case of forming a state in which the contact parts are directly fixed based on heat by welding, various welding methods such as ultrasonic welding, heating and pressure welding, hot air welding, and high-frequency welding can be used. Moreover, when the state in which the contact parts are directly fixed is formed by these methods, the sheet 20 and the linear transmission member 30 are in a state in which the contact parts are directly fixed based on the method. Specifically, for example, when the state in which the contact parts are directly fixed is formed by ultrasonic welding, the sheet 20 and the linear transmission member 30 are in a state in which the contact parts are directly fixed based on ultrasonic welding. Therefore, the above-mentioned welding fixation is a form of direct fixation of the contact parts.

[0086] It should be noted that the various configurations described in the above-mentioned embodiments and modifications may be appropriately combined as long as they do not contradict each other.
