     DESCRIPTION OF EMBODIMENT(S) 
     Description of Embodiment of Present Disclosure 
     Embodiments of the present disclosure are listed and described firstly. 
     A wiring member according to the present disclosure is as follows. 
     (1) A wiring member includes: a plurality of wire-like transmission members wired in a form including a main wire part and a branch wire part; and a sheet material including a main wire fixing part to which the main wire part is fixed a branch wire fixing part to which the branch wire part is fixed, wherein the branch wire fixing part is branched from the main wire fixing part, a branch wire support part is provided in the branch wire fixing part, and the branch wire support part extends along a longitudinal direction of the branch wire part, and is formed to have higher rigidity than each of the wire-like transmission members constituting the branch wire part. Accordingly, the branch wire part is supported by the branch wire support part, and when the wiring member is transported from a first operation position to a second operation position, bending of the branch wire part is suppressed. Thus, an operation of assembling the wiring member to the vehicle can be easily performed. 
     (2) The branch wire support part may be formed to be able to be bended and deformed in association with a plastic deformation between a straight state and a bending state. Accordingly, the wiring member can be formed into an appropriate form at a time of manufacture, transportation, and assembling to the vehicle. For example, the wiring member is manufactured while the branch wire support part is in a straight state, and subsequently, the wiring member is transported while the branch wire support part is in a bending state. Then, the wiring member is assembled to the vehicle while the branch wire support part is in a straight state again after the transportation of the wiring member. 
     (3) The branch wire support part may be a magnetic body. Accordingly, the wiring member with the branch wire support part can be attracted by a magnet. 
     (4) The branch wire support part may extend to a position overlapping with the main wire fixing part. Accordingly, bending of the branch wire part in a portion where the branch wire fixing part is branched from the main wire fixing part is suppressed. 
     (5) It is applicable that at least one main wire support part is provided in the main wire fixing part, and the main wire support part extends along a longitudinal direction of the main wire part, and is formed to have higher rigidity than each of the wire-like transmission members constituting the main wire part. Accordingly, the main wire part in the wiring member is supported by the main wire support member, and when the wiring member is transported from the first operation position to the second operation position, bending of the main wire part is suppressed. Thus, an operation of assembling the wiring member to the vehicle can be easily performed. 
     (6) The main wire fixing part may include a portion where the plurality of main wire support parts are provided at intervals along the longitudinal direction of the main wire part. Accordingly, the main wire part in the wiring member can be bended at a portion between the main wire support parts. 
     (7) The branch wire support part may be provided to have contact with the main wire support part. Accordingly, bending of the wiring member between the branch wire support part and the main wire support part is suppressed. 
     (8) The main wire support part may have higher rigidity than the branch wire support part. Accordingly, the main wire support part can firmly support the main wire part which is heavier than the branch wire part in many cases. 
     (9) The branch wire support part may include an external branch wire support part provided on an outer side of the plurality of wire-like transmission members each constituting the branch wire part along a parallel direction. Accordingly, an outer side part of the branch wire part along the parallel direction is supported by the external branch wire support part. 
     (10) The branch wire support part may include an internal branch wire support part provided on a position overlapping with the plurality of wire-like transmission members each constituting the branch wire part or between the plurality of wire-like transmission members. Accordingly, an inner side part of the branch wire part along the parallel direction is supported by the internal branch wire support part. 
     Details of Embodiment of Present Disclosure 
     Specific examples of a wiring member of the present disclosure are described hereinafter with reference to the drawings. The present invention is not limited to these examples, but is indicated by claims, and it is intended that meanings equivalent to claims and all modifications within a scope of claims are included. 
     Embodiment 1 
     A wiring member according to an embodiment 1 is described hereinafter.  FIG. 1  is a schematic plan view illustrating a wiring member  10  according to the embodiment 1.  FIG. 2  is a cross-sectional view along a II-II line in  FIG. 1 .  FIG. 3  is a cross-sectional view along a III-III line in  FIG. 2 .  FIG. 4  is an explanation illustrating a state where the wiring member  10  is raised. 
     The wiring member  10  includes a plurality of wire-like transmission members  20  and a sheet material  30 . Herein, the wiring member  10  further includes a branch wire support member  40 . The branch wire support member  40  is an example of a branch wire support part provided in the wiring member  10 . The branch wire support member  40  is an example of a branch wire support part provided separately from the sheet material  30 . An example that the branch wire support part is integrated with the sheet material is described hereinafter. A configuration of the branch wire support member provided separately from the sheet material can be applied to the branch wire support part provided integrally with the sheet material so far as consistent with the embodiments. 
     It is sufficient that the wire-like transmission member  20  is a wire-like member transmitting an electrical power or light, for example. For example, the wire-like transmission member  20  may be a general wire having a core wire  21  and a covering  22  around the core wire  21 , or may also be a bare conductive wire, a shielded wire, an enamel wire, a nichrome wire, or an optical fiber. 
     The wire-like transmission member  20  transmitting the electrical power may be various kinds of signal lines or various kinds of power lines. The wire-like transmission member  20  transmitting the electrical power 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  20  includes a transmission wire body transmitting an electrical power or light and a covering for covering the transmission wire body. When the wire-like transmission member  20  is a general wire, the transmission wire body is a core wire  21 , and the covering is an insulating covering  22 . The core wire  21  may be made up of a plurality of single wires  21   a . The plurality of single wires  21   a  may be stranded. In the example illustrated in  FIG. 2 , the plurality of wire-like transmission members  20  having the same diameter and structure are disposed on one sheet material  30 , however, it is sufficient that the diameter and the structure of each of the plurality of wire-like transmission members  20  are appropriately set, thus the wire-like transmission members  20  each having a different diameter and a structure, for example, may be disposed on the same sheet material  30 . 
     The wire-like transmission member  20  may be a single wire-like object or a composite object of a plurality of wire-like objects (a twisted wire and a cable made up of a plurality of wire-like objects covered by a sheath). A terminal and a connector C, for example, are appropriately provided in accordance with a connection state of the wire-like transmission member  20  and the other side member in an end portion of the wire-like transmission member  20 . 
     The plurality of wire-like transmission members  20  are wired to have a configuration including a main wire part  24  and a branch wire part  26 . The two branch wire parts  26  are provided herein. The two branch wire parts  26  are distinguished as branch wire parts  26 A and  26 B hereinafter. 
     The branch wire part  26 A is branched from one side portion in the main wire part  24 , and the branch wire part  26 B is branched from the other side portion in the main wire part  24 . The branch wire parts  26 A and  26 B are branched from positions different from each other along a longitudinal direction of the main wire part  24 . A longitudinal direction of the branch wire part  26 A is perpendicular to the longitudinal direction of the main wire part  24 . A longitudinal direction of the branch wire part  26 B is not parallel and perpendicular to the longitudinal direction of the main wire part  24 . That is to say, the longitudinal direction of the branch wire part  26 B intersects with the longitudinal direction of the main wire part  24  at an angle larger than 0 degree and smaller than 90 degrees. Needless to say, routes of the main wire part  24  and the branch wire part  26  are not limited thereto described above. For example, one branch wire part  26  may be provided, or three or more branch wire parts  26  may also be provided. For example, the two branch wire parts  26  may be branched from one side portion in the main wire part  24 . For example, the two branch wire parts  26  may be branched from the same position along the longitudinal direction of the main wire part  24 . 
     In the example illustrated in  FIG. 1 , the seven wire-like transmission members  20  are disposed on the sheet-like material  30 . The seven wire-like transmission members  20  are disposed along predetermined routes, respectively. The seven wire-like transmission members  20  are distinguished as the wire-like transmission members  20 A,  20 B,  20 C,  20 D,  20 E,  20 F, and  20 G in some cases hereinafter. Specifically, the wire-like transmission members  20 A and  20 B are wired to constitute only the main wire part  24  on the sheet material  30 . The wire-like transmission members  20 C and  20 D are wired so that some of them constitutes the main wire part  24  and the other some of them constitutes the branch wire part  26 A on the sheet material  30 . The wire-like transmission members  20 E and  20 F are wired so that some of them constitutes the main wire part  24  and the other some of them constitutes the branch wire part  26 B on the sheet material  30 . The wire-like transmission member  20 G is wired so that an intermediate portion thereof constitutes the main wire part  24 , one end portion thereof constitutes the branch wire part  26 A, and the other end portion thereof constitutes the branch wire part  26 B on the sheet material  30 . 
     The wire-like transmission member  20  is fixed to the sheet material  30 . The sheet material  30  keeps a wiring state of the wire-like transmission members  20 . The sheet material  30  includes a first base material  31  and a second base material  32  herein. The second sheet material  32  is omitted in  FIG. 1 . The first sheet material  31  covers one side of the wire-like transmission member  20 . The second sheet material  32  covers the other side (a side opposite to the first sheet material  31 ) of the wire-like transmission member  20 . An intermediate portion in the wire-like transmission member  20  is surrounded by the first sheet material  31  and the second sheet material  32 . Accordingly, suppressed is an exposure of the intermediate portion in the wire-like transmission member  20 . 
     Herein, the wire-like transmission member  20  is fixed to only the first sheet material  31  in the first sheet material  31  and the second sheet material  32 . A fixing state of the wire-like transmission member  20  and the first sheet material  31  is not particularly limited, however, bonding or welding may also be applied. The bonding indicates that two members are bonded to each other via an inclusion such as an adhesive agent or a double-sided adhesive tape. The welding indicates that resin contained in at least one of two members are melted and the two members are welded to each other without an intervention of an inclusion. Herein, at least one of resin contained in the covering  22  of the wirelike transmission member  20  and resin contained in the first sheet material  31  is melted and bonded to the other side member, thus the wirelike transmission member  20  and the first sheet material  31  are fixed to each other. 
     Materials constituting the first sheet member  31  and the second sheet material  32  are not particularly limited, however, the first sheet material  31  and second sheet material  32  are formed of materials containing resin of polyvinyl chloride (PVC), polyethylene terephthalate (PET), polypropylene (PP), or nylon, for example. The first sheet material  31  and the second sheet material  32  may be a fibrous material having fiber such as a non-woven cloth, a woven fabric, or a knitting fabric or a non-fiber material, for example. The non-fiber material may be a solid member with an inner portion evenly filled or a foam made up by foam molded resin. The first sheet material  31  and the second sheet material  32  may contain a material such as metal, for example. 
     The first sheet material  31  and the second sheet material  32  may be a single layer or may be a plurality of stacked layers. When the first sheet material  31  and the second sheet material  32  are made up of the plurality of stacked layers, it is considered that a resin layer and a resin layer are stacked, for example. It is also considered that a resin layer and a metal layer are stacked, for example. The first sheet material  31  and the second sheet material  32  may be made up of a non-fiber material layer and a non-fiber material layer overlapped with each other, a non-fiber material layer and a fiber material layer overlapped with each other, or a fiber material layer and a fiber material layer overlapped with each other. 
     The first sheet material  31  has a double-layered structure, for example. A first layer in the first sheet material  31  is a layer appropriate for fixation to the wire-like transmission member  20 . For example, the first layer is formed into a solid member, with an inner portion evenly filled, of the same material as that of the covering  22  of the wire-like transmission member  20 . The wire-like transmission member  20  is fixed on the first layer. The second layer is a layer enhancing a function of the sheet material  30 . The second layer is a non-woven cloth, for example. The first layer may be wholly or partially provided on the second layer  22 . For example, the first layer may be provided in the intermediate portion along a width direction of the second layer (a parallel direction of the wire-like transmission member  20 ), and needs not be provided in a side edge portion. For example, the first layer may be provided at intervals along the longitudinal direction of the second layer (the longitudinal direction of the wire-like transmission member  20 ). 
     The second sheet material  32  has a single-layered structure, for example. The second sheet material  32  is formed to have higher rigidity than the first sheet material  31 . The second sheet material  32  is formed to be a member of nylon as a material with an inner portion evenly filled, for example. The wire-like transmission member  20  is not fixed to the second sheet material  32 . An edge portion of the second sheet material  32  is fixed to the first sheet material  31 . A fixing state of the first sheet material  31  and the second sheet material  32  is not particularly limited, however, welding or bonding is also applicable. The second sheet material  32  may be fixed to the first layer or the second layer in the first sheet material  31 . 
     The sheet material  30  includes a main wire fixing part  34  and a branch wire fixing part  36 . The main wire fixing part  34  is a part where the main wire part  24  is fixed. The branch wire fixing part  36  is a part where the branch wire part  26  is fixed. The branch wire fixing part  36  is branched from the main wire fixing part  34 . That is to say, the branch wire fixing part  36  is connected to the main wire fixing part  34 . Herein, the branch wire fixing part  36  is branched from an intermediate portion of the main wire fixing part  34  in a longitudinal direction. 
     The branch wire support member  40  is formed into a rod-like shape. The branch wire support member  40  extends along a longitudinal direction of the branch wire part  26 . A horizontal section of the branch wire support member  40  has a circular shape. A horizontal section of the branch wire support member  40  may have a polygonal shape, for example. The branch wire support member  40  is formed so that the same horizontal section shape is continuously located in the longitudinal direction. The branch wire support member  40  may be formed so that the horizontal section shape is changed at the intermediate portion along the longitudinal direction. The branch wire support member  40  is fixed to the branch wire fixing part  36  at a base end side portion of the branch wire part  26 . 
     The branch wire support member  40  is formed to have higher rigidity than the wire-like transmission member  20  constituting the branch wire part  26 . It is sufficient that the branch wire support member  40  has rigidity so as to be able to suppress the branch wire part  26  hanging down in a bending state at a midway portion. It is sufficient that the branch wire support member  40  has rigidity to the extent of moderately bowing toward a tip end side of the branch wire part  26  in a state of supporting the branch wire part  26 . In the present example, the two branch wire support members  40  are provided on one branch wire part  26 . When the plurality of branch wire support members  40  are provided, it is sufficient that rigidity corresponding to the plurality of branch wire support members  40  is higher than that of the branch wire part  26 . Only one branch wire support member  40  may be provided on one branch wire part  26 , or three or more branch wire support members  40  may also be provided. 
     The two branch wire support members  40  are located on an outer side in both sides of the wire-like transmission member  20 . In other words, all of the wire-like transmission members  20  are sandwiched by the two branch wire support members  40  in the parallel direction of the wire-like transmission member  20 . Accordingly, the branch wire part  26  is hardly twisted. The branch wire support member  40  may be located between the wire-like transmission members  20 . 
     The branch wire support member  40  extends to a position overlapping with the main wire fixing part  34 . A line which is an extension line of a side edge portion of the main wire fixing part  34  extending in a band-like shape is defined as a boundary line L between the branch wire fixing part  36  and the main wire fixing part  34 . One end of the branch wire support member  40  passes over the boundary line L to reach the main wire fixing part  34 . One other end of the branch wire support member  40  reaches a tip end of the branch wire fixing part  36 . The branch wire support member  40  extends over the whole length of the branch wire fixing part  36 . One other end of the branch wire support member  40  does not pass over the tip end of the branch wire fixing part  36 . The other end of the branch wire support member  40  does not reach the connector C, and is not connected to the connector C. The other end of the branch wire support member  40  is not housed in a cavity in a connector housing. 
     The branch wire support member  40  is formed to be able to be bended and deformed in association with a plastic deformation between a straight state and a bending state (refer to  FIG. 3 ). It is applicable that the bending deformation in association with the plastic deformation can be performed only once or several times. The number of several times may be twice, three times, or more. The branch wire support member  40  is a wire-like member, for example. Herein, the straight state includes a state where the branch wire support member  40  bows in accordance with a self-weight of the wiring member  10 . The bending state includes a flexion state. Particularly, the bending state includes a state bending to be folded. 
     Herein, the branch wire support member  40  includes a core rod  41  and a covering  42 . The core rod  41  is formed to have higher rigidity than the wire-like transmission member  20  constituting the branch wire part  26 . The core rod  41  is formed to be able to be beaded and deformed in association with a plastic deformation between a straight state and a bending state several times. A material constituting the core rod  41  is not particularly limited, however, the core rod  41  is formed of a material containing metal such as iron, iron alloy, aluminum, aluminum alloy, copper, or copper alloy, for example. For example, the core rod  41  may be formed to be thicker than the single wire  21   a  in the core wire  21  of the wire-like transmission member  20 , or may also be formed to be thicker than the core wire  21  in which the single wires  21   a  are collected. The covering  42  covers a periphery of the core rod  41 . The covering  42  is softer than the core rod  41 . A material constituting the covering  42  is not particularly limited, however, the covering  42  is formed of a material containing resin, for example. The covering  42  may be made of the same material as that of the covering  22  of the wire-like transmission member  20 . 
     It is sufficient that the branch wire support member  40  has rigidity capable of supporting the branch wire part  26 . A thickness of the branch wire support member  40  is not particularly limited. The thickness of one branch wire support member  40  is preferably the same as or smaller than that of the thickest wire-like transmission member  20  in the wire-like transmission members  20  constituting the branch wire part  26 . Accordingly, increase in a thickness of the wiring member  10  in the branch wire part  26  can be suppressed. 
     The branch wire support member  40  is a magnetic body. Accordingly, as illustrated in  FIG. 4 , a magnet  92  provided on a tip end of a robot arm  90  attracts the wiring member  10  with the branch wire support member  40  disposed on a table  80 . As a result, the wiring member  10  with the branch wire support member  40  can be easily transported. The core rod  41  is a magnetic body herein. For example, when a material of the core rod  41  is stainless steel, the stainless steel may also be a ferrite stainless steel, or martensite stainless steel. 
     The branch wire support member  40  may be fixed to any of the first sheet material  31  and the second sheet material  32 . A fixing state between the branch wire support member  40  and the first sheet material  31  and between the branch wire support member  40  and the second sheet material  32  is not particularly limited, however, welding or bonding is also applicable. The branch wire support member  40  is welded to the first sheet material  31  herein. The covering  42  and the first sheet material  31  are welded to each other. 
     The branch wire support member  40  is surrounded by the first sheet material  31  and the second sheet material  32 . The second sheet material  32  is fixed to the first sheet material  31  on an outer side of the branch wire support member  40 . In the parallel direction of the wire-like transmission member  20 , a housing space of the branch wire support member  40  is not partitioned from a housing space of the wire-like transmission member  20  but is communicated therewith. 
     The branch wire support member  40  has the same rigidity along the longitudinal direction herein. The rigidity of the branch wire support member  40  on a base end side of the branch wire part  26  (referred to as the base end side support part hereinafter) may be higher than the rigidity of the branch wire support member  40  on a tip end side of the branch wire part  26  (referred to as the tip end side support part hereinafter). Accordingly, the branch wire support member  40  can firmly support the base end side of the branch wire part  26 . 
     For example, when a thickness, a material, and the number of the base end side support part are different from those of the tip end side support part, the base end side support part may have higher rigidity than the tip end side support part. Specifically, for example, when the thickness of the base end side support part is larger than that of the tip end side support part in a case where a property other than the thickness is the same, the base end side support part may have higher rigidity than the tip end side support part. For example, when the material of the base end side support part has higher rigidity (Young&#39;s modulus) than the tip end side support part in a ease where a property other than the material is the same, the base end side support part may have higher rigidity than the tip end side support part. For example, when the number of the base end side support parts parallel to each other is larger than that of the tip end side support part in a case where a property other than the number thereof is the same, the base end side support part may have higher rigidity than the tip end side support part. 
     Effect etc. of Embodiment 1 
     According to the wiring member  10  having the above configuration, the branch wire part  26  is supported by the branch wire support member  40 , thus when the wiring member  10  is transported from a first operation position to a second operation position, bending of the branch wire part  26  is suppressed. Thus, an operation of assembling the wiring member  10  to the vehicle can be easily performed. 
     More specifically, when the wiring member  10  is assembled to the vehicle, the wiring member  10  transported from the first operation position to the second operation position in some cases. At this time, the wiring member  10  disposed on the first operation position is raised and hangs in midair. Then, the wiring member  10  in the hanging state lands on the second operation position. At this time, when the rigidity of the branch wire part is low, the branch wire part is bended at the time of landing on the second operation position, and the form of the wiring member is different from the wiring form in the vehicle in some cases. In contrast, in the wiring member  10  according to the present disclosure, the branch wire part  26  is supported by the branch wire support member  40 , thus when the wiring member  10  lands on the second operation position, bending of the branch wire part  26  is suppressed. Thus, when the wiring member  10  lands on the second operation position, the wiring member  10  can keep the wiring form in the vehicle, and an operation can smoothly make a transition to an operation of fixing a terminal portion and an intermediate portion of the wiring member  10  to the vehicle (for example, an operation of connecting the connector C and an operation of fixing a clip). A sequence of operations from the operation of transporting the wiring member  10  to the operation of fixing the terminal portion and the intermediate portion of the wiring member  10  to the vehicle is automatically performed, a fixation error due to the bending of the branch wire part  26  can be suppressed. 
     The branch wire support member  40  is provided separately from the sheet material  30  as the branch wire support part, thus the branch wire support part can be provided by a member different from the sheet material  30 . Accordingly, the branch wire support part can easily have higher rigidity than the sheet material  30 . A design of the branch wire can be easily changed. 
     The branch wire support member  40  is formed to be able to be bended and deformed in association with the plastic deformation between the straight state and the bending state several times, thus the wiring member  10  can have the appropriate form at the time of manufacture, transportation, and assembling to the vehicle. For example, after the wiring member  10  is manufactured while the branch wire support member  40  is in the straight state, the wiring member  10  is transported while the branch wire support member  40  is the bending state. Then, the wiring member  10  is assembled to the vehicle while the branch wire support member  40  is in the straight state again after the transportation of the wiring member  10 . 
     The branch wire support member  40  is the magnetic body, thus the wiring member  10  with the branch wire support member  40  can be attracted by the magnet  92 . Accordingly, when the wiring member  10  is transported from the first operation position to the second operation position, the wiring member  10  can be attracted by the magnet  92  and transported. 
     The branch wire support member  40  extends to the position overlapping with the main wire fixing part  34 , thus the bending of the branch wire part  26  is suppressed at the portion where the branch wire fixing part  36  is branched from the main wire fixing part  34 . 
     Embodiment 2 
     A wiring member according to an embodiment 2 is described.  FIG. 5  is a schematic plan view illustrating a wiring member  110  according to the embodiment 2. In  FIG. 5  the second sheet material  32  is omitted in the manner similar to  FIG. 1 . In the description of the present embodiment, the same reference numerals are assigned to the similar constituent elements described above, and the description thereof will be omitted. 
     The wiring member  110  is different from the wiring member  10  in that the wiring member  110  further includes a main wire support member  50 . The wiring member  10  described above does not include a support part along the main wire part  24  but includes only the support part along the branch wire part  26 . In the meanwhile, the wiring member  110  further includes a support part along the main wire part  24 . The main wire support member  50  is an example of a main wire support part provided in the wiring member  10 . The main wire support member  50  is an example of a main wire support part provided separately from the sheet material  30 . The main wire support part may be integrated with the sheet material. A configuration of the branch wire support member  50  provided separately from the sheet material can be applied to the main wire support part provided integrally with the sheet material so far as consistent with the embodiments. 
     The main wire support member  50  is formed into a rod-like shape. The main wire support member  50  extends along a longitudinal direction of the main wire part  24 . A horizontal section of the main wire support member  50  has a circular shape. A horizontal section of the main wire support member  50  may have a polygonal shape, for example. The main wire support member  50  is formed so that the same horizontal section shape is continuously located in the longitudinal direction. The main wire support member  50  may be formed so that the horizontal section shape is changed at the intermediate portion along the longitudinal direction. The main wire support member  50  is fixed to the main wire fixing part  34 . 
     The main wire support member  50  is formed to have higher rigidity than the wire-like transmission member  20  constituting the main wire part  24 . It is sufficient that the main wire support member  50  has rigidity so as to be able to suppress the main wire part  24  hanging down in a bending state at a midway portion. It is sufficient that the main wire support member  50  has rigidity to the extent of moderately bowing toward a tip end side of the main wire part  24  in a state of supporting the main wire part  24 . When the plurality of main wire support members  50  are provided, it is sufficient that rigidity corresponding to the plurality of main wire support members  50  is higher than that of the main wire part  24 . 
     The main wire part  24  tends to have more wire-like transmission members  20  than the branch wire part  26 . Thus, the main wire part  24  tends to have a larger weight than the branch wire part  26 . When the main wire support member  50  and the branch wire support member  40  have rigidity corresponding to the main wire part and the branch wire part  26 , respectively, it is sufficient that the main wire support member  50  has higher rigidity than the branch wire support member  40 . In this case, excess rigidity of the branch wire support member  40  can be suppressed. 
     For example, when a thickness, a material, and the number of the main wire support member  50  are different from those of the branch wire support member  40 , the main wire support member  50  may have higher rigidity than the branch wire support member  40 . Specifically, for example, when the thickness of the main wire support member  50  is larger than that of the branch wire support member  40  in a ease where a property other than the thickness is the same, the main wire support member  50  may have higher rigidity than the branch wire support member  40 . For example, when the material of the main wire support member  50  has higher rigidity (Young&#39;s modulus) than the branch wire support member  40  in a case where a property other than the material is the same, the main wire support member  50  may have higher rigidity than the branch wire supper member  40 . For example, when the number of the main wire support members  50  parallel to each other is larger than that of the branch wire support members  40  parallel to each other in a case where a property other than the number thereof is the same, the main wire support member  50  may have higher rigidity than the branch wire support member  40 . 
     The same type of member as that of the main wire support member  50  may be adopted as the branch wire support member  40 . In this case, a common component is used for the main wire support member  50  and the branch wire support member  40 , thus the type of the component is reduced. 
     The main wire support member  50  may be formed to be able to be bended and deformed in association with a plastic deformation between a straight state and a bending state several times in the manner similar to the branch wire support member  40 . When the main wire support member  50  has high rigidity, there is a possibility that the main wire support member  50  is hardly bended and deformed in association with the plastic deformation between the straight state and the bending state. In this case, as illustrated in  FIG. 5 , it is sufficient that a position where the main wire support member  50  is not provided is set in the intermediate portion along the longitudinal direction of the main wire fixing part  34 . That is to say, it is sufficient that the main wire fixing part  34  includes a portion where the plurality of main wire support members  50  are provided at intervals along the longitudinal direction of the main wire part  24 . Accordingly, the main wire part  24  can be handed at a portion between the plurality of main wire support members  50 . 
     The main wire support member  50  may include a core rod and a covering, or may also include only a core rod. The main wire support member  50  may be or may not be a magnetic body. A core rod and a covering similar to the core rod  41  and the covering  42  can be adopted as the core rod and the covering of the main wire support member  50 . 
     A thickness of the main wire support member  50  is not particularly limited as long as the main wire support member  50  has rigidity capable of supporting the main wire part  24 . The thickness of one main wire support member  50  is preferably the same as or smaller than that of the thickest wire-like transmission member  20  in the wire-like transmission members  20  constituting the main wire part  24 . Accordingly, increase in the thickness of the wiring member  10  in the main wire part  24  can be suppressed. 
     The main wire support member  50  may be fixed to any of the first sheet material  31  and the second sheet material  32  in the main wire fixing part  34 . Welding or bonding, for example, may be adopted as a fixing state of the main wire support member  50  and the main wire fixing part  34  in the manner similar to that of the branch wire support member  40  and the branch wire fixing part  36 . A fixing state of the main wire support member  50  and the main wire fixing part  34  may be the sane as or different from that of the branch wire support member  40  and the branch wire fixing part  36 . 
     The main wire support member  50  is surrounded by the first sheet material  31  and the second sheet material  32 . The second sheet material  32  is fixed to the first sheet material  31  on an outer side of the main wire support member  50 . 
     The branch wire support member  40  is provided to have contact with the main wire support member  50 . Accordingly, bending of the wiring member  110  between the branch wire support member  40  and the main wire support member  50  is suppressed. It is applicable that an end surface of the branch wire support member  40  is provided to have contact with a side surface of the main wire support member  50  or an end surface of the main wire support member  50  is provided to have contact with a side surface of the branch wire support member  40 . The branch wire support member  40  may be provided separately from the main wire support member  50 . 
     Effect etc. of Embodiment 2 
     An effect similar to that of the wiring member  10  according to the embodiment 1 can be obtained also by the wiring member  110  having the above configuration. 
     According to the wiring member  110 , the main wire part  24  is supported by the main wire support member  50 , thus bending of the main wire part  24  is suppressed when the wiring member  110  is transported from the first operation position to the second operation position. Thus, an operation of assembling the wiring member  110  to the vehicle can be easily performed. Moreover, the main wire part  24  in the wiring member  110  can be bonded at a portion between the main wire support members  50 . 
     The branch wire support member  40  is provided to have contact with the main wire support member  50 , thus bending of the wiring member  110  between the branch wire support member  40  and the main wire support member  50  is suppressed. 
     The main wire part  24  tends to be heavier than the branch wire part  26 . Even in this case, the main wire support member  50  is configured to have higher rigidity than the branch wire support member  40 , thus the main wire support member  50  can firmly support the main wire part  24 . 
     Modification Example 
       FIG. 6  is a cross-sectional view illustrating a modification example of a fixing state of a branch wire support part and a sheet material  130 . In the example illustrated in  FIG. 6 , a branch wire support member  140  is surrounded by the first sheet material  131 . That is to say, formed in the first sheet material  131  is a surrounding part  138  surrounding the branch wire support member  140  while partitioning the branch wire support member  140  from the wire-like transmission member  20 . Accordingly, the branch wire support member  140  is fixed to the branch wire fixing part  36 . The surrounding part  138  may be sequentially or intermittently formed over the whole length along the longitudinal direction of the branch wire fixing part  36 . The surrounding part  138  may be formed in only one end portion and the other end portion of the branch wire fixing part  36 . The surrounding part  138  is formed by an edge portion of the first sheet material  131  in the parallel direction of the wire-like transmission member  20 , but may be formed by an intermediate portion of the first sheet material  131 . The second sheet material  132  covers the wire-like transmission member  20 , but does not cover the branch wire support member  140 . 
       FIG. 7  is a cross-sectional view illustrating another modification example of a fixing state of a branch wire support part and a sheet material  230 . In the example illustrated in  FIG. 7 , the branch wire support member  140  is surrounded by the first sheet material  31  and a second sheet material  232 . The second sheet material  232  is also fixed to the first sheet material  31  between the branch wire support member  140  and the wire-like transmission member  20 . In the parallel direction of the wire-like transmission member  20 , a housing space of the branch wire support member  140  is partitioned from a housing space of the wire-like transmission member  20 . The surrounding part  238  surrounding and partitioning the branch wire support member  140  from the wire-like transmission member  20  is formed by the first sheet material  31  and the second sheet material  232 . Accordingly, the main wire support member  140  is fixed to the branch wire fixing part  36 . The surrounding part  238  may be sequentially or intermittently formed over the whole length along the longitudinal direction of the branch wire fixing part  36 . The surrounding part  238  may be formed only one end portion and the other end portion of the branch wire fixing part  36 . 
       FIG. 8  is a cross-sectional view illustrating another modification example of fixing state of a branch wire support part and a sheet material  330 . In the example illustrated in  FIG. 8 , the branch wire support member  40  is provided on an outer surface side of a second sheet material  332 . The branch wire support member  40  is provided on an outer surface side of a fixing part fixed to the first sheet material  331  in the second sheet material  332 . Accordingly, contact of the branch wire support member  40  with the first sheet material  331  is suppressed. The branch wire support member  40  has contact with a flat surface on the outer surface side of the fixing part fixed to the first sheet material  331  in the second sheet material  332 . The branch wire support member  40  may also have contact with a curved surface of the second sheet material  332 . 
     The branch wire support member  40  is fixed to the second sheet material  332 . A fixing state of the branch wire support member  40  and the second sheet material  332  is not particularly limited, however, welding or bonding is also applicable. It is also applicable that a banding member such as an adhesive tape is wound around the branch wire support member  40  and the sheet material  330  in a state where the branch wire support member  40  and the sheet material  330  have contact with each other to fix the branch wire support member  40  and the second sheet material  332 . 
     The branch wire support member  40  does not preferably protrude to an outer side than a farthest portion of the second sheet material  332  along the thickness direction. The branch wire support member  40  does not preferably protrude to an outer side than an outer edge of the second sheet material  332  along the parallel direction. 
     The branch wire support member  40  is an example of an external branch wire support part. The external branch wire support part is provided on an outer side of the plurality of wire-like transmission members  20  constituting the branch wire part  26  along the parallel direction. An outer side part of the branch wire part  26  along the parallel direction is supported by the external branch wire support part. 
       FIG. 9  is a cross-sectional view illustrating another modification example of a fixing state of the branch wire support part  40  and the sheet material  30 . In the example illustrated in  FIG. 9 , the branch wire support member  40  is provided between the wire-like transmission members  20 . The branch wire support member  40  is an example of an internal branch wire support part. The internal branch wire support part is provided in a position overlapping with the plurality of wire-like transmission members  20  constituting the branch wire part  26  or a position between the plurality of wire-like transmission members  20 . An inner side part of the branch wire part  26  along the parallel direction is supported by the internal branch wire support part. 
     The branch wire support member  40  is provided in a center of the wire-like transmission member  20 . The branch wire support member  40  may be located in a position other than the center of the plurality of wire-like transmission members  20 . For example, when an odd number of the wire-like transmission members  20  are provided, it is sufficient that the branch wire support member  40  is provided adjacent to the wire-like transmission member  20  located in the center. In the example illustrated in  FIG. 9 , only one branch wire support member  40  is provided between the wire-like transmission members  20 , however, several the branch wire support members  40  may be provided. 
       FIG. 10  is a cross-sectional view illustrating a modification example of a branch wire support part. In the example illustrated in  FIG. 10 , a sheet material  430  includes a first sheet material  431  and a second sheet material  432 . A branch wire support part  432   b  is provided to be integral with the second sheet material  432 . The second sheet material  432  includes a body part  432   a  and a branch wire support part  432   b . The second sheet material  432  is integrally formed into a shape including a body part  432   a  and a branch wire support part  432   b.    
     The body part  432   a  is a part extending planarly. The body part  432   a  includes a part covering the wire-like transmission member  20  and a part fixed to the first sheet material  431 . 
     The branch wire support part  432   b  protrudes from the body part  432   a  in a thickness direction. Herein, the branch wire support part  432   b  protrudes to an outer surface side of the body part  432   a.  The branch wire support part  432   b  extends along the longitudinal direction of the wire-like transmission member  20 . The plurality of branch wire support parts  432   b  are formed. The plurality of branch wire support parts  432   b  are arranged at intervals along a parallel direction. Each branch wire support part  432   b  has a width dimension smaller than the body part  432   a.  Each branch wire support part  432   b  has a width dimension smaller than a part of the body part  432   a  covering the wire-like transmission member  20 . A width dimension of each branch wire support part  432   b  may be the same as, smaller than, or larger than an outer diameter of the wire-like transmission member  20 . When there are a plurality of wire-like transmission members having different outer diameters in one branch wire part, a width dimension of each branch wire support part  432   b  may be an intermediate dimension between a largest outer diameter and a smallest outer diameter. 
     The branch wire support part  432   b  is provided on an outer surface side of a part of the second sheet material  432  covering the wire-like transmission member  20 . Each branch wire support part  432   b  is provided in a position overlapping with the wire-like transmission member  20  or between the wire-like transmission members  20  along a parallel direction. Each branch wire support part  432   b  is an example of an internal branch wire support part. An inner side of the branch wire part is supported by the internal branch wire support part. 
     Each branch wire support part  432   b  may be provided on an outer side of the wire-like transmission member  20  along the parallel direction. That is to say, the branch wire support part  432   b  may be provided on an outer surface side of a part fixed to the first sheet material  31  in the second sheet material  432 . The branch wire support part in this case is an example of the external branch wire support part described above. 
     A horizontal section of each branch wire support part  432   b  has a polygonal shape. A corner portion of each branch wire support part  432   b  may be rounded. A horizontal section of each branch wire support part  432   b  may have a semicircular shape. 
     The covering  42  in the branch wire support member  40  is omitted in the branch wire support member  140  illustrated in  FIG. 6  and  FIG. 7 . Accordingly, when the rigidity of the branch wire support members  40  and  140  are substantially the same as each other, the branch wire support member  140  is thinner than the branch wire support member  40  by the thickness of the covering  42 . When the thickness of the branch wire support members  40  and  140  are substantially the same as each other, the core rod  41  of the branch wire support member  140  can be thicker than that of the branch wire support member  40 , thus the rigidity of the branch wire support member  140  is higher than that of the branch wire support member  40 . 
     A fixing state of the branch wire support member and the sheet material illustrated in  FIG. 6  and  FIG. 10  may be used for a fixing state of the main wire support member and the sheet material. 
     In the above description, the branch wire support part is the magnetic body, however, this configuration is not necessary. The branch wire support part may not be the magnetic body. 
     In the above description, the branch wire support member  40  extends to a position overlapping with the main wire fixing part  34 , however, this configuration is not necessary. The branch wire support member  40  may be provided so as not to overlap with the main wire fixing part  34 . For example, the branch wire support member may extend to a position of the boundary line L, or may extend to a position in front of the boundary line L. 
     Exemplified is the configuration that the branch wire support part is provided to range from one side to the other side of the branch wire fixing part  36  in the longitudinal direction, however, it goes without saying that the configuration is not limited thereto. For example, from a viewpoint of fitting the connector C more easily, also applicable is a configuration of partially removing the branch wire support part on a side of the connector C in the longitudinal direction of the branch wire fixing part  36 . When the bending is performed in the branch wire fixing part  36  on a side of the main wire fixing part  34  in the longitudinal direction of the branch wire fixing part  36 , also applicable is a configuration of partially removing the branch wire support part on the side of the main sire fixing part  34  in the longitudinal direction of the branch wire fixing part  36  from a viewpoint of easily performing the bending. 
     The configurations described in the embodiments and modification examples thereof can be appropriately combined as long as they are not contradictory. For example, exemplified are the case where the branch wire fixing part is integral with the second sheet material and the case where the branch wire fixing part is formed separately from the second sheet material, however, one of the configuration described in the example of the case of integral formation and the configuration described in the example of the case of separate formation can be appropriately applied to the other configuration.
