- FIG. 4 is a partial schematic cross-sectional view along a IV-IV line in FIG. 1 .
- the wiring member 10 is a member joined to a plurality of components mounted to a vehicle to transmit at least one of electricity or light between the components.
- the wiring member 10 includes a sheet material 20 and a wire-like transmission member 30 fixed on the sheet material 20 .
- the wire-like transmission member 30 is disposed on a main surface of the sheet material 20 , thus the wiring member 10 is formed flatly as a whole.
- the wiring member 10 may remain in a flat form in a state where the wiring member 10 is assembled to a vehicle, or may be in a bended form in a thickness direction.
- the sheet material 20 includes a first layer 22 formed into a sheet-like shape and a second layer 24 provided on a main surface of the first layer 22 .
- the first layer 22 defines an outer shape of the sheet material 20 , and in this point, the first layer 22 is a base material functioning as a base.
- the second layer 24 is a layer mediating a bonding of the first layer 22 and the wire-like transmission member 30 . That is to say, the second layer 24 is provided on the main surface of the first layer 22 , and the wire-like transmission member 30 is fixed to the second layer 24 , thus the wire-like transmission member 30 is hardly peeled from the sheet material 20 in a case where the wire-like transmission member 30 is fixed to the second layer 24 compared with a case where the wire-like transmission member 30 is fixed to the first layer 22 .
- Materials constituting the first layer 22 and the second layer 24 are not particularly limited, but may contain resin such as polyvinyl chloride (PVC), polyethylene (PE), polyethylene terephthalate (PET), and polypropylene (PP), for example.
- a structure of the base material is not particularly limited, however, a fiber material having fibers such as a woven cloth, a knitting cloth, and a non-woven cloth, for example, may be applicable, and a non-fiber material which does not have fibers such as a member made up by extrusion molding or injection molding.
- a foam made up by foam molding or a solid material which is not foam-molded but is uniformly solid may also be applicable.
- the other layer such a metal layer may be overlapped with the first layer 22 and the second layer 24 .
- the first layer 22 has a role as a base of the wiring member 10 , it is sufficient that the first layer 22 is excellent in tensile strength than the second layer 24 , for example.
- the second layer 24 is the layer mediating the bonding of the first layer 22 and the wire-like transmission member 30 , it is sufficient that the second layer 24 is fixed to the wire-like transmission member with larger force than to the first layer 22 .
- Adoptable as an example of such a combination is a case where the first layer 22 is a non-woven sheet, a woven sheet, and a knitted sheet, and a base resin of resin of the second layer 24 is the same as a base resin of resin constituting a surface of the wire-like transmission member 30 .
- the first layer 22 when a constituent fiber excellent in the tensile strength is used in the first layer 22 , the first layer 22 can be relatively soft and excellent in the tensile strength, thus such a fiber is appropriate as a base material functioning as a base.
- a minute gap caused by the fiber for example, is formed in the surface of the first layer 22 , thus when the second layer 24 melted by heat, for example, fills the gap, and is then hardened, the first layer 22 and the second layer 24 can be relatively firmly bonded. That is to say, the first layer 22 and the second layer 24 can be relatively firmly bonded by a type of anchor effect.
- a melting point of the first layer 22 is higher than that of the second layer 24 , thus the second layer 24 is melted to fill the gap of the first layer 22 easily.
- any material can be used as a material constituting the first layer 22 regardless of the resin constituting the surface of the wire-like transmission member 30 .
- the surface of the wire-like transmission member 30 is formed of polyvinyl chloride (PVC), polypropylene (PP), polyethylene terephthalate (PET), and polyethylene (PE), for example, may be used as the resin constituting the first layer 22 .
- the wire-like transmission member 30 can be relatively firmly bonded to the second layer 24 by welding the wire-like transmission member 30 to the second layer 24 , for example.
- the base resin of the covering on outer periphery of the wire-like transmission member 30 is PVC
- it is sufficient that the base resin of the second layer 24 is PVC.
- the adhesive agent generally has favorable adhesion properties on a member having favorable compatibility (affinity), and particularly has favorable adhesion properties on the same system of resin.
- the base resin of the resin of the second layer 24 is the same as that constituting the surface of the wire-like transmission member 30 , the wire-like transmission member 30 and the second layer 24 can be relatively firmly bonded by using an adhesive agent appropriate for the base resin.
- the second layer 24 may be made of resin softer than the first layer 22 as the other example of the above combination.
- the first layer 22 is harder than the second layer 24 , thus can be excellent in the tensile strength, for example, and a material suitable as the base material functioning as the base can be selected.
- the wire-like transmission member 30 can be embedded in the second layer 24 to some degree in fixing the wire-like transmission member 30 to the second layer 24 , thus a fixing region of the wire-like transmission member 30 in a circumferential direction can be increased. Accordingly, the fixing strength of the wire-like transmission member 30 can be increased.
- Flexibility of the first layer 22 and the second layer 24 can be changed by changing a ratio of a plasticizing agent to be added even in a case where a common base resin is used.
- the base resin of the first layer 22 and the second layer 24 is PVC and an amount of the plasticizing agent to be added is larger in the second layer 24 than in the first layer 22 , the second layer 24 can be softer than the first layer 22 .
- the base resin of the first layer 22 and the second layer 24 may not be PVC, however, PE, PP, and PET, for example, are also applicable.
- the second layer 24 may also be softened by changing a degree of polymerization of the resin as the base, copolymerizing the other resin, adding a modifier capable of increasing flexibility (for example, olefin system or styrene system thermoplastic elastomer).
- a modifier capable of increasing flexibility for example, olefin system or styrene system thermoplastic elastomer.
- the configuration of the second layer 24 is not limited to each example described above, however, any configuration is applicable as long as the fixing strength in fixing the wire-like transmission member 30 to the second layer 24 is higher than that in fixing the wire-like transmission member 30 to the first layer 22 .

FIG. 1 is a schematic plan view illustrating awiring member 10,FIG. 2 is a partial schematic cross-sectional view along a II-II line inFIG. 1 ,FIG. 3 is a partial schematic cross-sectional view along a line III-III inFIG. 1 , andFIG. 4 is a partial schematic cross-sectional view along a IV-IV line inFIG. 1 . - The
wiring member 10 is a member joined to a plurality of components mounted to a vehicle to transmit at least one of electricity or light between the components. Thewiring member 10 includes asheet material 20 and a wire-like transmission member 30 fixed on thesheet material 20. The wire-like transmission member 30 is disposed on a main surface of thesheet material 20, thus thewiring member 10 is formed flatly as a whole. Thewiring member 10 may remain in a flat form in a state where thewiring member 10 is assembled to a vehicle, or may be in a bended form in a thickness direction. - The
sheet material 20 includes afirst layer 22 formed into a sheet-like shape and asecond layer 24 provided on a main surface of thefirst layer 22. - The
first layer 22 defines an outer shape of thesheet material 20, and in this point, thefirst layer 22 is a base material functioning as a base. - The
second layer 24 is a layer mediating a bonding of thefirst layer 22 and the wire-like transmission member 30. That is to say, thesecond layer 24 is provided on the main surface of thefirst layer 22, and the wire-like transmission member 30 is fixed to thesecond layer 24, thus the wire-like transmission member 30 is hardly peeled from thesheet material 20 in a case where the wire-like transmission member 30 is fixed to thesecond layer 24 compared with a case where the wire-like transmission member 30 is fixed to thefirst layer 22. - Materials constituting the
first layer 22 and thesecond layer 24 are not particularly limited, but may contain resin such as polyvinyl chloride (PVC), polyethylene (PE), polyethylene terephthalate (PET), and polypropylene (PP), for example. A structure of the base material is not particularly limited, however, a fiber material having fibers such as a woven cloth, a knitting cloth, and a non-woven cloth, for example, may be applicable, and a non-fiber material which does not have fibers such as a member made up by extrusion molding or injection molding. When the base material is a non-fiber material made up by extrusion molding or injection molding, a foam made up by foam molding or a solid material which is not foam-molded but is uniformly solid may also be applicable. - The other layer such a metal layer may be overlapped with the
first layer 22 and thesecond layer 24. - Considering that the
first layer 22 has a role as a base of thewiring member 10, it is sufficient that thefirst layer 22 is excellent in tensile strength than thesecond layer 24, for example. - Considering that the
second layer 24 is the layer mediating the bonding of thefirst layer 22 and the wire-like transmission member 30, it is sufficient that thesecond layer 24 is fixed to the wire-like transmission member with larger force than to thefirst layer 22. - Adoptable as an example of such a combination is a case where the
first layer 22 is a non-woven sheet, a woven sheet, and a knitted sheet, and a base resin of resin of thesecond layer 24 is the same as a base resin of resin constituting a surface of the wire-like transmission member 30. - In this case, when a constituent fiber excellent in the tensile strength is used in the
first layer 22, thefirst layer 22 can be relatively soft and excellent in the tensile strength, thus such a fiber is appropriate as a base material functioning as a base. A minute gap caused by the fiber, for example, is formed in the surface of thefirst layer 22, thus when thesecond layer 24 melted by heat, for example, fills the gap, and is then hardened, thefirst layer 22 and thesecond layer 24 can be relatively firmly bonded. That is to say, thefirst layer 22 and thesecond layer 24 can be relatively firmly bonded by a type of anchor effect. In this case, a melting point of thefirst layer 22 is higher than that of thesecond layer 24, thus thesecond layer 24 is melted to fill the gap of thefirst layer 22 easily. - In this case, any material can be used as a material constituting the
first layer 22 regardless of the resin constituting the surface of the wire-like transmission member 30. For example, when the surface of the wire-like transmission member 30 is formed of polyvinyl chloride (PVC), polypropylene (PP), polyethylene terephthalate (PET), and polyethylene (PE), for example, may be used as the resin constituting thefirst layer 22. - When the base resin of the resin of the
second layer 24 is the same as that constituting the surface of the wire-like transmission member 30, the wire-like transmission member 30 can be relatively firmly bonded to thesecond layer 24 by welding the wire-like transmission member 30 to thesecond layer 24, for example. For example, when the base resin of the covering on outer periphery of the wire-like transmission member 30 is PVC, it is sufficient that the base resin of thesecond layer 24 is PVC. - Also based on an assumption of a case were the wire-
like transmission member 30 is fixed to thesecond layer 24 by an adhesive agent, the adhesive agent generally has favorable adhesion properties on a member having favorable compatibility (affinity), and particularly has favorable adhesion properties on the same system of resin. When the base resin of the resin of thesecond layer 24 is the same as that constituting the surface of the wire-like transmission member 30, the wire-like transmission member 30 and thesecond layer 24 can be relatively firmly bonded by using an adhesive agent appropriate for the base resin. - The
second layer 24 may be made of resin softer than thefirst layer 22 as the other example of the above combination. - In this case, the
first layer 22 is harder than thesecond layer 24, thus can be excellent in the tensile strength, for example, and a material suitable as the base material functioning as the base can be selected. - When the
second layer 24 is softer than thefirst layer 22, the wire-like transmission member 30 can be embedded in thesecond layer 24 to some degree in fixing the wire-like transmission member 30 to thesecond layer 24, thus a fixing region of the wire-like transmission member 30 in a circumferential direction can be increased. Accordingly, the fixing strength of the wire-like transmission member 30 can be increased. - Flexibility of the
first layer 22 and thesecond layer 24 can be changed by changing a ratio of a plasticizing agent to be added even in a case where a common base resin is used. For example, when the base resin of thefirst layer 22 and thesecond layer 24 is PVC and an amount of the plasticizing agent to be added is larger in thesecond layer 24 than in thefirst layer 22, thesecond layer 24 can be softer than thefirst layer 22. The base resin of thefirst layer 22 and thesecond layer 24 may not be PVC, however, PE, PP, and PET, for example, are also applicable. Thesecond layer 24 may also be softened by changing a degree of polymerization of the resin as the base, copolymerizing the other resin, adding a modifier capable of increasing flexibility (for example, olefin system or styrene system thermoplastic elastomer). When thefirst layer 22 and thesecond layer 24 are made of a common base resin, thefirst layer 22 and thesecond layer 24 can be relatively firmly bonded by melting or an adhesive agent, for example. - The configuration of the
second layer 24 is not limited to each example described above, however, any configuration is applicable as long as the fixing strength in fixing the wire-like transmission member 30 to thesecond layer 24 is higher than that in fixing the wire-like transmission member 30 to thefirst layer 22. - Herein, the
first layer 22 includes amain part 22 a and a plurality of (four herein)extension parts 22 b to hold the plurality of wire-like transmission members 30 along branched routes. - The
main part 22 a is formed into an elongated rectangular shape. Each of the plurality ofextension parts 22 b is formed into an elongated rectangular shape. - The two
extension parts 22 b extend to one lateral side from both end portions of themain part 22 a. The other twoextension parts 22 b extend to one lateral side from an intermediate portion of themain part 22 a in an extension direction. A base end portion of the plurality ofextension parts 22 b is overlapped with one lateral edge portion of themain part 22 a. The base end portion of the plurality ofextension parts 22 b may also be bonded to one lateral edge portion of themain part 22 a by welding, an adhesive agent, and a double-sided tape, for example. - Herein, the plurality of
extension parts 22 b extend to one lateral side of themain part 22 a, however, some of them may extend from the other lateral side. Herein, the plurality ofextension parts 22 b extend in a direction perpendicular to themain part 22 a, but may also extend in an oblique direction with respect to themain part 22 a. - Lengths of the plurality of
extension parts 22 b may be the same or different. Theextension part 22 b may be omitted. - A fixing
member 40 is attached to both lateral portions of the base end portion of theextension part 22 b overlapping with themain part 22 a. The fixingmember 40 is a member referred to a clamp or a clip, including abase part 42, acolumn part 44, and a lockingpart 46. Thebase part 42 is formed into a plate-like shape. Thecolumn part 44 stand on thebase part 42. The lockingpart 46 is provided on a tip end of thecolumn part 44. The lockingpart 46 is formed to be able to be inserted into and locked to ahole 52 formed in a fixingtarget member 50. The lockingpart 46 is inserted into and locked to thehole 52 formed in the fixing target, thus the fixingmember 40 is fixed to the fixingtarget member 50. Thebase part 42 functions as a retaining part and the lockingpart 46 functions as a decent part in the state where the fixingmember 40 is fixed to the fixingtarget member 50. The fixingmember 40 is an integrated molded component made of resin by injection molding, for example. - The fixing
member 40 is inserted into both lateral portions of the base end portion of theextension part 22 b overlapping with themain part 22 a. In the state where the fixingmember 40 is fixed to the fixing target member, the portion of the base end portion of theextension part 22 b overlapping with themain part 22 a is fixed between thebase part 42 and the fixingtarget member 50, and thewiring member 10 can be fixed to the fixingmember 40. - The
base part 22 a and the plurality ofextension parts 22 b described above may be integrally formed. - The
second layer 24 includes a plurality of partialsecond layers like transmission member 30. - A region where the partial
second layers like transmission member 30 is provided, thus the wire-like transmission member 30 is described. - It is sufficient that the wire-
like transmission member 30 is a wire-like member transmitting electricity or light. For example, the wire-like transmission member 30 may be a general wire having a core wire and an insulating covering around the core wire, or may also be a bare conductive wire, an enamel wire, a nichrome wire, or an optical fiber. The wire-like transmission member 30 transmitting electricity and the wire-like transmission member 30 transmitting light may be arranged in parallel or only one of them may be disposed. - The wire-
like transmission member 30 transmitting the electricity may be various kinds of signal lines or various kinds of power lines. The wire-like transmission member 30 transmitting the electricity may be used as an antenna or coil, for example, transmitting or receiving a signal or electrical power to or from a space. - The wire-
like transmission member 30 is considered to include atransmission wire body 32 transmitting electricity or light and a covering 34 covering thetransmission wire body 32. When the wire-like transmission member 30 is a general wire, for example, thetransmission wire body 32 corresponds to a core wire, and the covering 34 corresponds to an insulating covering. The core wire includes one or a plurality of strands. Each strand is formed of a conductive material such as copper, copper alloy, aluminum, and aluminum alloy, for example. When the core wire is made up of the plurality of strands, the plurality of strands are preferably stranded. The insulating covering is formed of a resin material such as PVC or PE extrusion-molded around the core wire. - The
sheet material 20 and the wire-like transmission member 30 are fixed to each other. Thesheet material 20 and the wire-like transmission member 30 are fixed to each other by a contact area fixation. The contact area fixation indicates that a portion where thesheet material 20 and the wire-like transmission member 30 have contact with each other is stuck and fixed. - Applicable as the configuration of the contact area fixation are a contact area indirect fixation and a contact area direct fixation, or both fixations may also be used together in different regions. Herein, the contact area indirect fixation indicates that the
sheet material 20 and the wire-like transmission member 30 are indirectly stuck and fixed via an adhesive agent, for example, provided therebetween. The contact area direct fixation indicates that thesheet material 20 and the wire-like transmission member 30 are directly stuck and fixed without an intervention of the adhesive agent, for example, which is separately provided. Considered in the contact area direct fixation is that resin included in at least one of thesheet material 20 and the wire-like transmission member 30 is melted, thus thesheet material 20 and the wire-like transmission member 30 are stuck and fixed, for example. In the description hereinafter, thesheet material 20 and the wire-like transmission member 30 are in the state of the contact area direct fixation. - In forming the state of such a contact area direct fixation, the resin is considered to be melted by heat or a solvent, for example. That is to say, the state of the contact area direct fixation may be the state of the contact area direct fixation by the heat or the state of the contact area direct fixation by the solvent. The contact area direct fixation by the heat is preferable.
- At this time, a means of forming the state of the contact area direct fixation is not particularly limited, but a known means such as welding, fusion, and melting joint can be used. For example, when the state of the contact area direct fixation by the heat is formed by welding, various welding means such as ultrasonic welding, heating-pressurizing welding, hot air welding, and high frequency welding can be adopted. When the state of the contact area direct fixation is formed by these means, the
sheet material 20 and the wire-like transmission member 30 are in the state of the contact area direct fixation by these means. Specifically, when the state of the contact area direct fixation is formed by the ultrasonic welding, for example, thesheet material 20 and the wire-like transmission member 30 are in the state of the contact area direct fixation by the ultrasonic welding. - In the case of the contact area direct fixation, only one of the resin included in the
sheet material 20 and the resin included in the covering 34 of the wire-like transmission member 30 may be melted, or both of them may be melted. In the former case, the resin which has been melted is stuck on an outer surface of the resin which has not been melted, and a relatively clear interface may be formed in some cases. In the latter case, there may be a case where both the resins are mixed and a clear interface is not be formed. Particularly, when the covering 34 of the wire-like transmission member 30 and thesheet material 20 include compatible resin such as the same resin material, for example, there may be a case where both the resins are mixed and a clear interface is not be formed. - Herein, the
wiring member 10 includes a plurality of wire-like transmission members 30. The plurality of wire-like transmission members 30 are wired on thefirst layer 22 in the following configuration. - That is to say, intermediate portions of the plurality of wire-
like transmission members 30 in the extension direction are disposed along themain part 22 a of thefirst layer 22. Each of the end portions of the plurality of wire-like transmission members 30 is bended at a position of anyextension part 22 b and disposed along thecorresponding extension part 22 b. - Some of the plurality of wire-
like transmission members 30 are branched from the other wire-like transmission members 30 at a position corresponding to the twoextension parts 22 b closer to the intermediate portion of themain part 22 a in the plurality ofextension parts 22 b. In this portion, some of the wire-like transmission members 30 are disposed to be bended and directed to theextension part 22 b. Some of the wire-like transmission members 30 are disposed to intersect with the other wire-like transmission member 30 and be directed to theextension part 22 b (refer to anintersection position 31 inFIG. 1 ). Some of the plurality of wire-like transmission members 30 are disposed to be bended at the end portion of themain part 22 a and directed to theextension part 22 b in the end portion of themain part 22 a. - Each end portion of the plurality of wire-
like transmission members 30 is connected to aconnector 60 at the end portion of theextension part 22 b. When the wire-like transmission member 30 is an electrical wire, theconnector 60 is an electrical connector in which a terminal connected to an end portion of the electrical wire is housed in a connector housing. When theconnector 60 is connected to a connector of the other side component, a plurality of components are electrically connected or connected to transmit and receive an optical signal via the wire-like transmission member 30. - The plurality of partial
second layers second layer 24 are provided to be separated from each other along the extension direction of the wire-like transmission member 30 described above. Herein, each of the partialsecond layers second layers like transmission members 30 passing through a partial region in the partial region in the extension direction of themain part 22 a or theextension part 22 b in the partial region. However, it is also applicable that each of the partialsecond layers like transmission members 30 passing through a partial region in the extension direction of themain part 22 a or theextension part 22 b in the partial region. - The partial
second layers like transmission members 30 are branched. - In this manner, at least one wire-
like transmission member 30 is bended in a position where the plurality of wire-like transmission members 30 are branched. Thus, the partialsecond layers like transmission member 30 is bended in the branch part. Herein, the partialsecond layers like transmission member 30 bended in the branch position but also in a region corresponding to the wire-like transmission member 30 provided straight. That is to say, in each position where the plurality of wire-like transmission members 30 are branched, one partialsecond layer 25 a (or 25 b) is provided in a region corresponding to the bended wire-like transmission member 30 and the wire-like transmission member 30 disposed straight. - The partial
second layer 25 a is provided in a region where the plurality of wire-like transmission members 30 intersect with each other. That is to say, in the position where the plurality of wire-like transmission members 30 are branched, there is a case where at least one wire-like transmission member 30 intersects with the other wire-like transmission member 30 (refer to the intersection position 31). The partialsecond layer 25 a is provided in a region where the plurality of wire-like transmission members 30 intersect with each other in the branch part. Thus, thesecond layer 25 a is fixed to the wire-like transmission members 30 intersecting with each other in theintersection position 31 in a position where thesecond layer 25 a sandwiches theintersection position 31. - Described herein is an example the
intersection position 31 is generated in the position where the plurality of wire-like transmission members 30 are branched. However, the plurality of wire-like transmission members 30 may intersect with each other in a portion other than the branch position for a purpose of switching an order of arrangement in accordance with an arrangement of terminals of connectors, for example. The partial second layer may also be provided in a region where the plurality of wire-like transmission members 30 intersect with each other in a portion other than the branch position. - The partial
second layer 26 is provided in a region keeping a state where the wire-like transmission member is bended. - Herein, the plurality of wire-
like transmission members 30 are bended in both end portions of themain part 22 a, and the partialsecond layer 26 is provided in a region keeping a state where the plurality of wire-like transmission members 30 are bended in the both end portions of themain part 22 a. - Assumable as the region keeping the state where the plurality of wire-
like transmission members 30 are bended is a region including the position where the wire-like transmission member 30 is bended itself. Accordingly, the bended part itself in the wire-like transmission member 30 is held by the partialsecond layer 26 along a predetermined route on thefirst layer 22. Herein, each partialsecond layer 26 fixes the bended position of the plurality of wire-like transmission members 30 to thefirst layer 22. - In the example illustrated in
FIG. 1 , the partialsecond layer 26 is formed into a shape extending to the position where the plurality of wire-like transmission members 30 are bended and a position adjacent to the position where the plurality of wire-like transmission members 30 are bended. However, as illustrated inFIG. 5 , the partialsecond layer 126 may be provided in a local region centering on the position where the plurality of wire-like transmission members 30 are bended. - The region keeping the state where the plurality of wire-
like transmission members 30 are bended needs not necessarily include the position where the wire-like transmission member 30 is bended. For example, as illustrated inFIG. 6 , the pair of partialsecond layers 226 may be provided on both sides of the position where the wire-like transmission member 30 is bended along the route of the wire-like transmission member 30. The pair of partialsecond layers 226 keep a posture of the wire-like transmission member 30 constant on the both sides of the position where the wire-like transmission member 30 is bended, thus the bended state of the wire-like transmission member 30 is also kept constant. - The partial
second layer 27 is provided on a terminal portion of thesheet material 20, that is a terminal portion of theextension part 22 b herein. The partialsecond layer 26 may be provided to have contact with an edge of the terminal of theextension part 22 b, or may also be provided in a position 1 cm or less away from the edge of the terminal of theextension part 22 b. - The partial
second layer 28 is provided in a region where the plurality of wire-like transmission members 30 are not branched or bended but extend straight in themain part 22 a. - The partial
second layer 29 is provided in a region where the plurality of wire-like transmission members 30 are not branched or bended but extend straight in theextension part 22 b. - The plurality of wire-
like transmission members 30 are fixed to the partialsecond layers second layers FIG. 2 ). - The plurality of wire-
like transmission members 30 are not fixed to thesheet material 20 in the region where the partialsecond layers FIG. 3 ). The wire-like transmission member 30 may be fixed to thefirst layer 22 also in a region in thesheet material 20 where the partialsecond layers - The
sheet material 20 described above can be manufactured by bonding the partialsecond layers first layer 22, for example. - According to the
wiring member 10 having such a configuration, the wire-like transmission member 30 can be fixed to thesheet material 20 as firmly as possible by thesecond layer 24. Thesecond layer 24 includes the plurality of partialsecond layers like transmission member 30, thus a weight and cost for materials of thewiring member 10 can be reduced compared with the case where the second layer is provided on the whole main surface of thesheet material 20. - The wire-
like transmission members 30 are bended or intersect with each other in the branch part of the wire-like transmission members 30, thus there is a possibility that the fixing strength of the wire-like transmission members 30 fixed to thesheet material 20 is reduced. The partialsecond layers like transmission members 30 are branched, thereby being able to keep the state where the plurality of wire-like transmission members 30 are branched, thus the wire-like transmission member 30 can be effectively fixed to thesheet material 20. - Particularly, the partial
second layers like transmission members 30 are bended in the branch positions, thus the state where the plurality of wire-like transmission member 30 are bended in the branch parts can be effectively kept. - In the
intersection position 31 of the plurality of wire-like transmission members 30, the wire-like transmission member 30 on the side away from thesheet material 20 has a small fixing region fixed to thesheet material 20. The partialsecond layer 25 a is provided in the region where the plurality of wire-like transmission members 30 intersect with each other, thus the state where the plurality of wire-like transmission members 30 intersect with each other can be effectively kept. - There is a possibility that force of the wire-
like transmission member 30 recovering the original shape acts in the position where the plurality of wire-like transmission members 30 are bended. The partialsecond layer 26 is provided in the region where the wire-like transmission member 30 is bended, thus the state where the wire-like transmission member 30 is bended can be effectively kept. - Particularly, the partial
second layers like transmission member 30 is bended, thus the state where the wire-like transmission member 30 is bended can be effectively kept. - Also in the case where the partial
second layers 226 are provided on both sides of the position where the wire-like transmission member 30 is bended, the portions on both sides of the position where the wire-like transmission member 30 is bended can be kept in a constant posture, thus the bended state of the wire-like transmission member 30 can be effectively kept. - There is a possibility that force in a direction of peeling the wire-
like transmission member 30 from thesheet material 20 acts in the terminal portion of thesheet material 20 when theconnector 60 is moved, for example. The partialsecond layer 27 is provided in the terminal portion of thesheet material 20, thus the area ranging from the wire-like transmission member 30 to the terminal portion of thesheet material 20 can be firmly held. - Lengths of the partial
second layers main part 22 a and the extension direction of theextension part 22 b). The lengths of the partialsecond layers like transmission members 30 than the position where the wire-like transmission member 30 is held in the straight state. In the example illustrated inFIG. 1 , the length of the partialsecond layer 26 disposed in the bended position of the wire-like transmission member 30 is set larger than those of the partialsecond layers like transmission member 30. Accordingly, the lengths of the plurality of partialsecond layers like transmission member 30 can be fixed to thesheet material 20 as firmly as possible, and a weight and cost for materials of thewiring member 10 can be reduced. - When the lengths of the partial second layers are different, they may be changed in at least two levels, but may also be changed in multiple levels. When widths of the plurality of partial
second layers second layers second layers like transmission members 30 to be held. - The intervals between the plurality of partial second layers in the direction along the extension direction of the wire-
like transmission member 30 may the same or different. -
FIG. 7 illustrates an example of changing intervals between a plurality of partialsecond layers like transmission member 30. -
FIG. 7 illustrates a schematic plan view of a part of awiring member 310 according to a modification example. - In the
wiring member 310, afirst layer 322 of thesheet material 320 includes an arc band-like part 322 a and a straight band-like part 322 b extending from both ends of the arc band-like part 322 a. The plurality of wire-like transmission members 30 are disposed along an extension direction of thefirst layer 322. The plurality of wire-like transmission members 30 extend from one straight band-like part 32 b to be connected to aconnector 360. - The
second layer 324 includes the plurality of partialsecond layers second layers 325 are provided on the arc band-like part 322 a, and the plurality of partialsecond layers 326 are provided on the straight band-like part 322 b. The interval between the plurality of partialsecond layers 325 and the interval between the partialsecond layer 325 and the partialsecond layer 326 adjacent thereto in the arc band-like part 322 a is smaller than the interval between the plurality of partialsecond layers 326 in the straight band-like part 322 b. - The partial
second layers like transmission members 30 are bended and a surrounding region thereof, thus the state where the wire-like transmission members 30 are bended can be effectively kept. In the meanwhile, the partialsecond layers 326 are provided at a relatively large interval in the position where the plurality of wire-like transmission members 30 are disposed straight, thus the weight and cost for materials of thewiring member 10 can be reduced. - The partial second layer may be provided closer to each other in the position where the plurality of wire-
like transmission members 30 are branched or the terminal portion, for example, than in the other portion. Also inFIG. 7 , the two partialsecond layer 326 are provided at a relatively closer interval in the terminal portion than in the other portion. - When the intervals between the partial second layers are different, it may be changed in at least two levels, but may also be changed in multiple levels.
- In a
wiring member 410 according to a modification example illustrated inFIG. 8 , the partialsecond layers like transmission member 30 and are provided on thefirst layer 22. Herein, the plurality of wire-like transmission members 30 are disposed in a parallel state in the partialsecond layers second layers like transmission members 30 located on both end sides, - A
cover 420 is attached to thesheet material 20 to cover at least part of the wire-like transmission member 30 via the portion of the partialsecond layers like transmission member 30.

Thecover 420 attached to the partialsecond layer 26 covers the bended position of the wire-like transmission members 30. - The partial
second layers like transmission member 30, thus when thecover 420 is made of the same material as a constituent resin around the wire-like transmission member 30. for example, thecover 420 can be fixed to thefirst layer 22 relatively firmly via the partialsecond layers - Accordingly, the wire-
like transmission member 30 can be firmly fixed to thesheet material 20 by the partialsecond layers like transmission member 30 where the relatively firm fixation is necessary, and this configuration is also suitable for attaching thecover 420 to thesheet material 20 with covering the wire-like transmission member 30. - The cover may cover the -
like transmission member 30 with a larger region. For example, the cover may cover the wire-like transmission member 30 on thewhole sheet material 20, for example. - Each configuration described in the embodiments and modification examples thereof can be appropriately combined as long as they are not contradictory.
- For example, in the above embodiment, the
main part 22 a or theextension part 22 b may be curved to have an arc-like shape.
