     Description of Embodiments 
     Specific examples of a support member, a wiring member with a support member, and an attachment structure for a wiring member are described below with reference to the drawings. Note that the present disclosure is not limited to these examples and is defined by the scope of the claims, and all modifications that are equivalent to or within the scope of the claims are included. 
     [Embodiments] 
     A support member, a wiring member with a support member, and an attachment structure for a wiring member according to embodiments will be described below.  FIG. 1  is a perspective view illustrating a support member  10  according to an embodiment.  FIG. 2  is a front view illustrating the support member  10  according to the embodiment.  FIG. 3  is a plan view illustrating the support member  10  according to the embodiment.  FIG. 4  is a cross-sectional view taken along line IV-IV of  FIG. 3 .  FIG. 5  is a cross-sectional view taken along line V-V of  FIG. 3 . 
     &lt;Support Member&gt; 
     First, a rod-like member  80  to which the support member  10  is attached will be described. The rod-like member  80  is a member installed in a vehicle. The rod-like member  80  is a member that reinforces the vehicle to increase the rigidity of the frame of the vehicle, examples including a reinforcement, a beam, a reinforcing bar, and the like. The reinforcement may be reinforcement for the instrument panel installed behind the instrument panel, for example. The rod-like member  80  is constituted by a plurality of rod-like portions connected to one another in the radial direction. In this example, the plurality of rod-like portions include a first rod-like portion  81  and a second rod-like portion  82 . The first rod-like portion  81  and the second rod-like portion  82  have a circular transverse cross-section. The first rod-like portion  81  and the second rod-like portion  82  are cylindrical. The second rod-like portion  82  is narrower than the first rod-like portion  81 . In this example, the outer diameter of the second rod-like portion  82  is approximately half of the outer diameter of the first rod-like portion  81 . However, the rod-like member  80  is not limited to that described above. For example, the rod-like member  80  may be constituted by three or more rod-like portions connected together. Also, for example, the transverse cross-section of the first rod-like portion and the second rod-like portion may be a shape other than a circle, such as a polygon. Also, for example, the first rod-like portion and the second rod-like portion may have a column-like shape. Also, for example, the first rod-like portion and the second rod-like portion may have the same thickness. Also, for example, the outer diameter of the second rod-like portion may be greater or less than half of the outer diameter of the first rod-like portion. 
     At a connection portion  83  of the first rod-like portion  81  and the second rod-like portion  82 , a predetermined region in the circumferential direction of each rod-like portion overlaps. In this example, a region approximately one third of the second rod-like portion  82  in the circumferential direction overlaps with the first rod-like portion  81 . In the example illustrated in  FIG. 1 , at the connection portion  83 , the circumferential surface of the first rod-like portion  81  remains as is, while the circumferential surface of the second rod-like portion  82  is partially interrupted. At the connection portion  83 , the two end surfaces of the second rod-like portion  82  in the circumferential direction are in contact with the circumferential surface of the first rod-like portion  81 . Naturally, the shape of the first rod-like portion  81 , the second rod-like portion  82 , and the connection portion  83  are not limited to that described above. For example, circumferential surfaces of the first rod-like portion  81  and the second rod-like portion  82  may be in contact. 
     The rod-like member  80  may be formed via molding with the first rod-like portion  81  and the second rod-like portion  82  connected. The rod-like member  80  may be formed by joining via welding the separately formed first rod-like portion  81  and second rod-like portion  82 . 
     In the rod-like member  80 , from the connected section of the first rod-like portion  81  and the second rod-like portion  82 , only the first rod-like portion  81  extends on one side and only the second rod-like portion  82  extends on the other side (see  FIG. 6 ). Hereinafter, when observing the rod-like member  80  along the longitudinal direction, the connected section of the first rod-like portion  81  and the second rod-like portion  82  may be referred to as a connection part  85 , the portion where only the first rod-like portion  81  extends may be referred to as a first part  86 , and the portion where only the second rod-like portion  82  extends may be referred to as a second part  87 . The rod-like member may be formed in a shape omitting either one or both of the first part  86  and the second part  87 . 
     A locking recess portion  84  is formed in the rod-like member  80 . A locking projection  28  provided on the support member  10  engages with the locking recess portion  84 . The locking recess portion  84  is formed with a shape and at a position that corresponds to the locking projection  28 . The locking recess portion  84  is formed on both the first rod-like portion  81  and the second rod-like portion  82 . In the connection part  85 , a plurality of the locking recess portions  84  are formed at intervals in the axial direction in the first rod-like portion  81 . In the connection part  85 , a plurality of the locking recess portions  84  are formed at intervals in the axial direction in the second rod-like portion  82 . 
     Note that the locking recess portion  84  is also formed in the first part  86  and the second part  87  (see  FIGS. 9 and 10 ). A support member  90  for a first part, described below, attaches to the locking recess portion  84  formed in the first part  86 . A support member  100  for a second part, described below, attaches to the locking recess portion  84  formed in the second part  87 . 
     A line L 1  in  FIG. 2  is a line that runs through a center C 1  of the first rod-like portion  81  and a center C 2  of the second rod-like portion  82 . A line L 2  in  FIG. 2  is a line that runs through the center C 1  of the first rod-like portion  81  and a center of the locking recess portion  84  formed on the first rod-like portion  81 . A line L 3  in  FIG. 2  is a line that runs through the center C 2  of the second rod-like portion  82  and a center of the locking recess portion  84  formed on the first rod-like portion  81 . A line L 4  in  FIG. 2  is a tangent line common to both the first rod-like portion  81  and the second rod-like portion  82 . A gap is formed between the tangent line L 4  common to the first rod-like portion  81  and the second rod-like portion  82  in the rod-like member  80  and the connection portion  83 . 
     &lt;Support Member&gt; 
     The support member  10  according to the embodiment will now be described. The support member  10  attaches to the rod-like member  80 . The support member  10  is a member for attaching a wiring member  50 , described below, to the rod-like member  80 . The support member  10  is provided with an engagement portion  20 . The support member  10  is further provided with a body portion  30  and an attachment portion  40 . A slit S is formed in the support member  10 . 
     The engagement portion  20  is configured to fit over the plurality of rod-like portions  81 ,  82  and engage with the outer circumferential portion of the rod-like member  80 . The engagement portion  20  includes a first engagement portion  22  and a second engagement portion  24 . The first engagement portion  22  is the portion that covers the first rod-like portion  81 . The second engagement portion  24  is the portion that covers the second rod-like portion  82 . The first engagement portion  22  and the second engagement portion  24  are joined at the end portions in the circumferential direction. The portion where the first engagement portion  22  and the second engagement portion  24  are joined may be referred to as a joined portion  26 . 
     The end portion of the first engagement portion  22  on the opposite side to the joined portion  26  in the circumferential direction corresponds to a first end portion of the engagement portion  20  in the circumferential direction. The end portion of the second engagement portion  24  on the opposite side to the joined portion  26  in the circumferential direction corresponds to a second end portion of the engagement portion  20  in the circumferential direction. The positions of the first end portion and the second end portion of the engagement portion  20  in the circumferential direction are not particularly limited. However, in this example, the first end portion and the second end portion of the engagement portion  20  in the circumferential direction extend to a position beyond the line L 1 . The position of the first end portion of the engagement portion  20  in the circumferential direction relative to the center C 1  of the first rod-like portion  81  and the position of the second end portion of the engagement portion  20  in the circumferential direction relative to the center C 2  of the second rod-like portion  82  are similar. In other words, an angle a 1  formed by the line L 1  and the line L 2  is the same as an angle a 2  formed by the line L 1  and the line L 3 . It can be said that the first engagement portion  22  and the second engagement portion  24  are similar regarding the portion beyond the line L 1 . 
     The locking projection  28  is provided at the first end portion of the engagement portion  20  in the circumferential direction. In a similar manner, the locking projection  28  is also provided at the second end portion of the engagement portion  20  in the circumferential direction. The locking projection  28  is configured to lock together with the locking recess portion  84 . The engagement portion  20  is locked together with the rod-like member  80  by locking together the locking projections  28  on both end portions of the engagement portion  20  in the circumferential direction with the corresponding locking recess portions  84 . In this manner, the engagement portion  20  is aligned with the rod-like member  80  with respect to the longitudinal direction, the circumferential direction, and the radial direction. 
     The portion of the engagement portion  20  that covers the connection portion  83  is formed recessed toward the connection portion  83 . The circumferential end portion of the first engagement portion  22  on the joined portion  26  side comes into contact with the first rod-like portion  81  at a position beyond a contact point between the common tangent line L 4  and the first rod-like portion  81 . The circumferential end portion of the second engagement portion  24  on the joined portion  26  side comes into contact with the second rod-like portion  82  at a position beyond a contact point between the common tangent line L 4  and the second rod-like portion  82 . The joined portion  26  is joined at a position with a small gap formed between the joined portion  26  and the connection portion  83 . The joined portion  26  is bent in the opposite direction to the first engagement portion  22  and the second engagement portion  24 . Thus, when a force is applied in the direction in which the engagement portion  20  extends, stress tends to be concentrated at the joined portion  26 . 
     The body portion  30  is contiguous with the engagement portion  20  in the axial direction. The axial direction of the support member  10  is parallel with the axial direction of the rod-like member  80 . The portion of the body portion  30  that covers the connection portion  83  is formed in a flat shape. Specifically, the body portion  30  includes a first body portion  32 , a second body portion  34 , and a third body portion  36 . The first body portion  32  is the portion that covers the first rod-like portion  81 . The second body portion  34  is the portion that covers the second rod-like portion  82 . The third body portion  36  is the portion where the first body portion  32  and the second body portion  34  are joined. The third body portion  36  is the portion that covers the connection portion  83 . The third body portion  36  is formed flat. 
     To describe in more detail, the first body portion  32  is the portion that extends from the intersection point between the common tangent line L 4  and the first rod-like portion  81  to the circumferential first end portion side of the engagement portion  20 . The first body portion  32  extends around the first rod-like portion  81 . The length dimension of the first body portion  32  in the circumferential direction is one fourth of the circumferential length of the first rod-like portion  81 . The second body portion  34  is the portion that extends from the intersection point between the common tangent line L 4  and the second rod-like portion  82  to the circumferential second end portion side of the engagement portion  20 . The second body portion  34  extends around the second rod-like portion  82 . The length dimension of the second body portion  34  in the circumferential direction is one fourth of the circumferential length of the second rod-like portion  82 . The third body portion  36  extends from the intersection point between the common tangent line L 4  and the first rod-like portion  81  to the intersection point between the common tangent line L 4  and the second rod-like portion  82 . The third body portion  36  extends in the same direction as the common tangent line L 4 . Thus, the third body portion  36  is not recessed toward the connection portion  83  of the first rod-like portion  81  and the second rod-like portion  82 . 
     The slit S is formed between the engagement portion  20  and the body portion  30 . In this example, the engagement portion  20 , the body portion  30 , and the engagement portion  20  are contiguous in this order in the axial direction. The slit S is provided on both sides of the body portion  30  in the axial direction. The slit S includes a first slit  51  and a second slit S 2 . The first slit  51  is formed on the first rod-like portion  81  side. The second slit S 2  is formed on the second rod-like portion  82  side. The second slit S 2  is formed with a greater depth than the first slit  51 . The depth of the slit S being deep refers to the size of the dimension in the radial direction being large. 
     More specifically, a dimension d 1  in  FIG. 4  is the depth dimension of the first slit S 1 . A dimension d 2  in  FIG. 4  is the depth dimension of the second slit S 2 . The dimension d 2  is greater than the dimension d 1 . Note that the dimensions d 1 , d 2  are dimensions from the outer surface of the engagement portion  20  or the body portion  30  to the terminating end of the slits S 1 , S 2  in the direction in which the line L 1  extends. 
     The second slit S 2  is formed extending beyond the joined portion  26  and into the first engagement portion  22  side. The first slit  51  and the second slit S 2  are formed so as to meet the first rod-like portion  81  at axisymmetric positions. In  FIG. 4 , a line L 5  is a line that runs through the center C 1  of the first rod-like portion  81  and the terminating end of the first slit  51 . In  FIG. 4 , a line L 6  is a line that runs through the center C 1  of the first rod-like portion  81  and the terminating end of the second slit S 2 . An angle a 3  formed by the line L 1  and the line L 5  is the same as an angle a 4  formed by the line L 1  and the line L 6 . The circumferential length of the support member  10  at the portion where the slit S is formed is one fourth of the circumferential length of the first rod-like portion  81 . 
     The third body portion  36  is located at the terminating end of the second slit S 2 . Thus, the slit S can be said to be formed in the body portion  30 . The slit S may be formed in the engagement portion  20 . 
     The first body portion  32  is located at the terminating end of the first slit S  1 . The first slit S 1  is formed extending in the circumferential direction to an intermediate portion of the first body portion  32 . The second slit S 2  does not reach the contact point between the common tangent line L 4  and the first rod-like portion  81 . A portion of the first body portion  32  is joined to the first engagement portion  22  in the axial direction. 
     The second slit S 2  is formed extending to an intermediate portion of the third body portion  36 . The second slit S 2  does not reach the contact point between the common tangent line L 4  and the first rod-like portion  81 . A portion of the third body portion  36  is joined to the first engagement portion  22  in the axial direction. The second body portion  34  and the third body portion  36  are not joined to the second engagement portion  24  and the joined portion  26  in the axial direction. The second slit S 2  may reach the contact point between the common tangent line L 4  and the first rod-like portion  81 . 
     The engagement portion  20  is shorter than the body portion  30  in the axial direction. In other words, the width dimension of the engagement portion  20  in the axial direction is less than the width dimension of the body portion  30  in the axial direction. Also, the width dimension of the slit S in the axial direction is less than the width dimension of the engagement portion  20  in the axial direction. The slit S is a groove with a width dimension. This allows the engagement portion  20  and the body portion  30  to not interfere with one another when the engagement portion  20  deforms. The slit may be a cut with no width dimension. 
     The wiring member  50  is provided in an attachable manner on the outer side of the engagement portion  20  and the body portion  30 . In this example, the wiring member  50  is provided in an attachable manner on the attachment portion  40  with the wiring member  50  disposed on the outer side of the engagement portion  20  and the body portion  30 . The attachment portion  40  includes a first attachment portion  41  and a second attachment portion  46 . The first attachment portion  41  is provided on the circumferential first end portion of the support member  10 . The second attachment portion  46  is provided on the circumferential second end portion of the support member  10 . In this example, the first attachment portion  41  and the second attachment portion  46  are provided projecting from the body portion  30 . 
     In this example, the first attachment portion  41  is provided in a manner allowing a sheet  70 , described below, provided on the wiring member  50  to be attached. The first attachment portion  41  includes a projection piece  42  and a locking portion  43 . The projection piece  42  projects from the circumferential first end portion of the body portion  30 . The projection direction of the projection piece  42  is a direction orthogonal to the line L 1 . The locking portion  43  is provided on the outer surface of the projection piece  42 . The locking portion  43  includes a pillar portion  44  and a cap portion  45 . The pillar portion  44  is provided projecting parallel with the line L 1  from the outer surface of the projection piece  42 . The cap portion  45  is provided on the tip of the pillar portion  44 . The cap portion  45  is formed in a truncated cone shape. The cap portion  45  is formed tapering toward the tip of the pillar portion  44 . The portion of the cap portion  45  on the base end side of the pillar portion  44  is formed to be thicker than the pillar portion  44 . The locking portion  43  is inserted and locked in a hole  77 , described below, formed in the sheet  70  of the wiring member  50 . 
     The second attachment portion  46  is provided in a manner allowing a connector C including a cassette Hc, described below, to be attached. The second attachment portion  46  includes a projection piece  47 . The projection piece  47  projects from the circumferential second end portion of the body portion  30 . The projection direction of the projection piece  47  is a direction orthogonal to the line L 1 . A locking hole  48  is formed in the projection piece  47 . The locking hole  48  extends through the projection piece  47  in the thickness direction. The connector C including the cassette Hc is attached to the second attachment portion  46  by inserting the projection piece  47  into the cassette Hc and locking the projection of the cassette Hc into the locking hole  48 . 
     The operation of attaching the support member  10  to the rod-like member  80  will now be described. In the example illustrated in  FIG. 5 , the first engagement portion  22  and the second engagement portion  24  are simultaneously engaged with the rod-like member  80 . Naturally, however, the support member  10  may be attached to the rod-like member  80  by first engaging the first engagement portion  22  or the second engagement portion  24  with the rod-like member  80 , and then engaging the other with the rod-like member  80 . 
     In the example illustrated in  FIG. 5 , the support member  10  is moved in a direction orthogonal to the line L 1  and attached to the rod-like member  80 . When the support member  10  is moved toward the rod-like member  80 , the first engagement portion  22  and the second engagement portion  24  come into contact with the rod-like member  80 . By applying a force to the support member  10  in this state, the first engagement portion  22  and the second engagement portion  24  open outward and elastically deform as illustrated in by the two-dot chain lines in  FIG. 5 . At this time, on the first engagement portion  22  side, the circumferential first end portion of the engagement portion  20  mainly opens outward and elastically deforms pivoting about the portion (the terminating end side portion of the first slit S 1 ) joined to the first body portion  32 . Also, on the second engagement portion  24  side, the circumferential second end portion of the engagement portion  20  mainly opens outward and elastically deforms pivoting about the joined portion  26  and therearound. As the rod-like member  80  is moved further inside the support member  10 , the first engagement portion  22  and the second engagement portion  24  transition from opening to elastically returning. Then, when the rod-like member  80  is housed at a predetermined position inside the support member  10 , the first engagement portion  22  and the second engagement portion  24  elastically return until the locking projection  28  locks into the locking recess portion  84 . In this manner, the support member  10  is put into a state of being attached to the rod-like member  80 . 
     &lt;Attachment Structure for a Wiring Member and Wiring Member with a Support Member&gt; 
     Next, an attachment structure for a wiring member and a wiring member with a support member according to the embodiment will be described.  FIG. 6  is a decomposition plan view of an attachment structure for a wiring member according to the embodiment.  FIG. 7  is a decomposition plan view of a wiring member with a support member according to the embodiment.  FIG. 8  is a cross-sectional view taken along line VIII-VIII of  FIG. 6 .  FIG. 9  is a cross-sectional view taken along line IX-IX of  FIG. 6 .  FIG. 10  is a cross-sectional view taken along line X-X of  FIG. 6 . 
     The attachment structure for a wiring member corresponds to a structure including the wiring member  50  attached to the rod-like member  80  via the support member  10 . In other words, the attachment structure for a wiring member is a structure including the support member  10  attached to the rod-like member  80  and the wiring member  50  attached to the support member  10 . Note that of the process of attaching the support member  10  to the rod-like member  80  and the process of attaching the wiring member  50  to the support member  10 , either process may be performed first. In other words, the wiring member  50  may be first attached to the support member  10 , and then the support member  10  to the rod-like member  80 . Alternatively, the support member  10  may be first attached to the rod-like member  80 , and then the wiring member  50  to the support member  10 . 
     The wiring member with a support member is a member including the wiring member  50  attached to the support member  10 . The wiring member  50  is supported by the support member  10 . 
     The attachment structure for a wiring member and the wiring member with a support member are further provided with, separate from the support member  10  described above, the support member  90  for the first part (simply referred to as the support member  90  below) and the support member  100  for the second part (simply referred to as the support member  100  below). The support member  90  attaches to the first part  86 . The support member  100  attaches to the second part  87 . The support members  90 ,  100  are attached at a position with a gap between the support members  90 ,  100  and the support member  10  in the axial direction. 
     The support member  90 , in a similar manner to the support member  10 , includes an engagement portion  91 , a body portion  92 , and an attachment portion  93 . The engagement portion  91  and the body portion  92  are connected in the axial direction. The engagement portion  91  and the body portion  92  are formed with a shape that corresponds to the first rod-like portion  81 . A slit  94  is formed between the engagement portion  91  and the body portion  92 . The attachment portion  93  is provided on the body portion  92 . As the attachment portion  93 , the same portions as the first attachment portion  41  and the second attachment portion  46  may be provided. 
     The support member  100 , in a similar manner to the support member  10 , includes an engagement portion  101 , a body portion  102 , and an attachment portion  103 . The engagement portion  101  and the body portion  102  are connected in the axial direction. The engagement portion  101  and the body portion  102  are formed with a shape that corresponds to the second rod-like portion  82 . A slit  104  is formed between the engagement portion  101  and the body portion  102 . The attachment portion  103  is provided on the body portion  102 . As the attachment portion  103 , the same portions as the first attachment portion  41  and the second attachment portion  46  may be provided. 
     &lt;Wiring Member&gt; 
     The wiring member  50  is a wiring member  50  for a vehicle that is connected to a component installed in the vehicle and transmits electricity or light to the component. Thus, the wiring member  50  includes a transmission member for transmitting electricity or light. The wiring member  50  is formed flat. In the example described below, the wiring member  50  is a wiring body  52  with a sheet. The wiring body  52  with a sheet includes a plurality of linear transmission members  60  and the sheet  70 . Note that in the example illustrated in  FIG. 7 , the linear transmission members  60  extending along the same path are illustrated as a single line. Accordingly, the linear transmission members  60  illustrated as a single line in  FIG. 7  may be thought as the plurality of linear transmission members  60 . 
     The linear transmission members  60  are only required to be members with a linear shape for transmitting electricity, light, or the like. For example, the linear transmission members  60  may be typically electrical wires including a core wire and a cover around the core wire, or may be naked lead wires, shielded wires, enamel wires, nichrome wires, optical fibers, or the like. 
     The linear transmission members  60  for transmitting electricity may be various signal lines, or various electric power lines. The linear transmission members  60  for transmitting electricity may be used as an antenna, coil, or the like that transmits to space or receives from space signals or power. 
     The linear transmission members  60  include a transmission line body that transmits electricity, light, or the like and a cover that covers the transmission line body. In a case where the linear transmission member  60  is a typical electrical wire, the transmission line body is a core wire  62  and the cover is an insulating cover  64 . The core wire  62  may be constituted by a plurality of individual wires. The plurality of individual wire may be twisted. The diameter, structure, and the like of the plurality of linear transmission members  60  arranged on one sheet  70  may be set as appropriate, and the arranged linear transmission members  60  may have the same diameter and structure, or the linear transmission members  60  with different diameters, structures, and the like may be arranged on the same sheet  70 . 
     The linear transmission members  60  may be a single linear object or may be a composite object of a plurality of linear objects (twisted wires, cables with a sheath covering a plurality of linear objects bundled together, or the like). A terminal, connector, or the like is provided on the end portion of the linear transmission members  60  as appropriate depending on the connection method of the linear transmission members  60  with the partner member. 
     In this example, the connector C is provided on the end portion of the linear transmission members  60 . The connector C connects to the connector on the partner side provided on an electronic component or the like, for example. In this example, the connector C is provided on one side portion of the wiring member  50 . The connector C is formed with the end portions of the linear transmission members  60  housed in the cavity of a housing H. The housing H may be fixed directly to the sheet  70  or may not be fixed. The cassette Hc is provided on the housing H. One side portion of the wiring member  50  is fixed to the support member  10  by the second attachment portion  46  being inserted into the cassette Hc and fixed. 
     In this example, a plurality of the connectors C are provided on one side portion of the wiring member  50 . The plurality of connectors C are provided at intervals in the longitudinal direction of the rod-like member  80 . The plurality of connectors C are provided in a manner allowing for connection in the same direction, however, the plurality of connectors C may connect in different directions. 
     The plurality of linear transmission members  60  are preferably routed on the sheet  70  along a path in the vehicle. By routing the plurality of linear transmission members  60  on the sheet  70  along a path in the vehicle, the path of the plurality of linear transmission members  60  is restricted, and installation of the wiring member  50  in the vehicle is simplified. 
     The plurality of linear transmission members  60  are arranged side by side and fixed on the sheet  70 . The sheet  70  maintains the linear transmission members  60  in this wiring arrangement. In this example, the sheet  70  is provided on only one surface of the linear transmission members  60 , however the sheet  70  may be provided on both surfaces of the linear transmission members  60 . 
     The sheet  70  includes a sheet body  71  and an attachment piece  76 . The linear transmission members  60  are routed on the sheet body  71 . The sheet body  71  includes a first sheet body  72 , a second sheet body  73 , and a third sheet body  74 . The first sheet body  72  is the portion located on the support member  10 . The second sheet body  73  is the portion located on the support member  90 . The third sheet body  74  is the portion located on the support member  100 . In the example illustrated in  FIG. 6 , the first sheet body  72  and the second sheet body  73  are joined, however, the first sheet body  72  and the second sheet body  73  may not be joined. In the example illustrated in  FIG. 6 , the first sheet body  72  and the third sheet body  74  are joined, however, the first sheet body  72  and the third sheet body  74  may not be joined. In other words, the sheet  70  may not be provided in the portions between the support members  10 ,  90 ,  100  in the longitudinal direction of the linear transmission members  60 . 
     The attachment piece  76  projects from the side edge of the first sheet body  72 , the second sheet body  73 , and the third sheet body  74 . The attachment piece  76  is provided at a position corresponding to the projection piece  42 . The hole  77  is formed in the attachment piece  76 . The hole  77  is provided at a position corresponding to the locking portion  43 . The hole  77  is formed smaller than the cap portion  45 . One side portion of the sheet body  71  is attached to the support members  10 ,  90 ,  100  by inserted and locking the cap portion  45  in the hole  77 . By attaching the attachment piece  76  to the first attachment portion  41  and attaching the connector C to the second attachment portion  46 , the wiring member  50  is attached to the support members  10 ,  90 ,  100 . 
     How the linear transmission members  60  and the sheet  70  are fixed together is not particularly limited, and bonding, welding, or the like may be used. Bonding refers to using an adhesive, double sided adhesive tape, or other intermediary to join two members together. Welding refers to melting the resin in at least one of two members and joining the two members together without using an intermediary. In this example, the linear transmission members  60  and the sheet  70  are fixed together by melting at least one of the resin in the insulating cover  64  of the linear transmission members  60  and the resin in the sheet  70  and joining the two members together. 
     The material of the sheet  70  is not particularly limited. However, the sheet  70  may be made from a material including a resin, such as polyvinyl chloride (PVC), polyethylene terephthalate (PET), polypropylene (PP), nylon, and the like. The sheet  70  may be a fiber material containing fiber including a nonwoven fabric, a fabric, a knitted fabric, or the like, or may be a non-fiber material. A non-fiber material may be a solid member with its inside uniformly filled, a foamed body formed by foaming a resin, or the like. The sheet  70  may also include a material such as a metal. 
     The sheet  70  may be a single layer or may be multilayer. In a case where the sheet  70  is multilayer, for example, it is plausible that resin layers are stacked on one another. Also, for example, it is plausible that resin layers and metal layers are stacked on one another. Furthermore, the sheet  70  may be formed by stacking non-fiber material layers and non-fiber material layers on one another, may be formed by stacking non-fiber material layers and fiber material layers on one another, or may be formed by stacking fiber material layers and fiber material layers on one another. 
     The sheet  70  is a two layer structure, for example. The first layer of the sheet  70  is a layer for fixing the linear transmission members  60 . For example, the first layer is formed as a solid member with its inside uniformly filled with the same resin material as the insulating cover  64  of the linear transmission members  60 . The linear transmission members  60  are fixed on the first layer. The second layer is a layer for increasing the function of the sheet  70 . For example, the second layer is a nonwoven fabric. The first layer may be provided in the entire area the second layer is provided or provided partially in the area the second layer is provided. For example, the first layer may be provided in only an intermediate portion of the second layer in the width direction (the arrangement direction of the linear transmission members  60 ) and not provided at the side edge portions. Also, for example, the first layer may be provided at intervals in the longitudinal direction (longitudinal direction of the linear transmission members  60 ) of the second layer. The sheet  70  has sufficient flexibility to bend around the support member  10  from a flat state. 
     On the linear transmission members  60  routed on the support member  10 , linear transmission members  60 A,  60 B that extend outward from the support member  10  in the axial direction are present. On the linear transmission members  60  routed on the support member  10 , linear transmission members  60 A,  60 B,  60 C,  60 D that bend on the support member  10  are present. The linear transmission members  60 C,  60 D bend on the support member  10  to connect to the connector C provided on the side of the sheet  70 . The linear transmission members  60 A,  60 B extend from the first part  86  of the rod-like member  80  toward the second part  87  of the rod-like member  80 . Because the first rod-like portion  81  and the second rod-like portion  82  are offset in terms of position in the radial direction, the linear transmission members  60 A,  60 B need to bend at the first part  86 , the second part  87 , or therebetween. In this example, the linear transmission members  60 A,  60 B bend at the connection part  85 . 
     Next, let&#39;s consider a case where the linear transmission members  60 A,  60 B do not bend at the connection part  85  and bend at the first part  86  or the second part  87 . In this case, the linear transmission members  60 A,  60 B may be routed to extend beyond the end surface of the first rod-like portion  81  or the end surface of the second rod-like portion  82 . When the wiring member  50  is first formed flat and then attached bending around the support member  10 , a difference in paths may occur in the linear transmission members. This path difference may occur when the linear transmission member extends beyond the end surface of the first rod-like portion  81  or the end surface of the second rod-like portion  82 . Depending on the path difference, the linear transmission members may experience a tensile force, the linear transmission members  60  may lift off the sheet  70 , or the like. 
     Thus, in this example, the linear transmission members  60 A,  60 B bend at the connection part  85 . Accordingly, when the wiring member  50  is first formed flat and then attached bending around the support member  10 , a difference in paths is less likely to occur in the linear transmission members  60 A,  60 B. This makes it less likely that the linear transmission members  60 A,  60 B experience a tensile force or that the linear transmission members  60 A,  60 B lift off the sheet  70 . 
     Also in this example, the linear transmission members  60 A,  60 B bend at the third body portion  36 . Accordingly, the linear transmission members  60 A,  60 B bend at the portion held flat even after the wiring member  50  is attached to the support member  10 . 
     Next, let&#39;s consider a case where the linear transmission members  60 A,  60 B bend on the joined portion  26  of the engagement portion  20 . In this case, the sheet  70  on which the linear transmission members are fixed is held flat, and a gap may be formed between the sheet  70  and the joined portion  26 . Thus, the sheet  70  may deform toward the joined portion  26 . At this time, the linear transmission members may also deform toward the joined portion  26 . Because of this deformation, the linear transmission members may experience a tensile force, the linear transmission members may lift off the sheet  70 , or the like. 
     Thus, in this example, the linear transmission members  60 A,  60 B bend at the third body portion  36 . This makes the sheet  70  less likely to deform and also makes the linear transmission members  60 A,  60 B less likely to deform. This makes it less likely that the linear transmission members  60 A,  60 B experience a tensile force or that the linear transmission members  60 A,  60 B lift off the sheet  70 . 
     In this example, of the linear transmission members  60  and the sheet  70 , the sheet  70  is disposed on the support members  10 ,  90 ,  100  side. This helps prevent the linear transmission members  60  rubbing against the circumferential edge of the slits S  94 ,  104 . This also helps prevent the linear transmission members  60  coming into contact with the rod-like member  80  at portions where the support members  10 ,  90 ,  100  are not present. Of the linear transmission members  60  and the sheet  70 , the linear transmission members  60  may also be disposed on the support members  10 ,  90 ,  100  side. In this case, the sheet  70  is disposed on the outer side of the linear transmission members  60  to protect the linear transmission members  60  from the peripherally located members. This also, helps prevent the linear transmission members  60  from lifting off the sheet  70 . 
     &lt;Effects and the Like&gt; 
     According to the support member  10 , the wiring member with a support member, and the support structure for a wiring member configured as described above, the support member  10  is attached, via the engagement portion  20 , to the rod-like member  80  including the plurality of rod-like portions  81 ,  82  connected in the radial direction. By using the support member  10 , the wiring member  50  can be supported by the rod-like member  80  including the plurality of rod-like portions  81 ,  82  connected in the radial direction. 
     Because the slit S is formed between the engagement portion  20  and the body portion  30 , when the engagement portion  20  is engaged with the rod-like member  80 , the engagement portion  20  can easily deform with a small force, and the engagement portion  20  can be easily engaged with the rod-like member  80 . 
     Because the second slit S 2  is formed deeper than the first slit  51 , when the engagement portion  20  is engaged with the rod-like member  80 , the engagement portion  20  can easily deform with a small force, and the engagement portion  20  can be easily engaged with the rod-like member  80 . 
     Because the engagement portion  20  is shorter than the body portion  30  in the axial direction, when the engagement portion  20  is engaged with the rod-like member  80 , the engagement portion  20  can easily deform with a small force, and the engagement portion  20  can be easily engaged with the rod-like member  80 . 
     Because the third body portion  36  of the body portion  30  that covers the connection portion  83  is formed flat, when the flat wiring member  50  is supported by the third body portion  36 , the flat wiring member  50  resists deflection. 
     Because the joined portion  26  of the engagement portion  20  that covers the connection portion  83  is formed recessed toward the connection portion  83 , the engagement portion  20  is more likely to deform pivoting about the joined portion  26  and therearound. 
     The wiring member  50  includes the plurality of linear transmission members  60  and the sheet  70  that holds the plurality of linear transmission members  60  in arrangement. This can help keep the height dimension of the wiring member  50  from the support member  10  low. 
     [Modified Example] 
     In the support member  10 , the body portion  30  may be omitted. In other words, the support member may be formed with a shape where the engagement portion  20  is continuous in the axial direction. In the support member  10 , even in a case where the body portion  30  is provided, the slit S may be omitted. For example, in a case such as where the amount of deformation needed for the engagement portion  20  to engage with the rod-like member  80  is low, it is plausible to omit the slit S. 
     It is not necessary to use the wiring body  52  with a sheet as the flat wiring member  50 . As the flat wiring member, a flexible flat cable (FFC), a flexible printed circuit (FPC), or the like may be used. Also, the wiring member may not be flat. For example, the wiring member may be the plurality of linear transmission members  60  bundled together via a binding member. 
     The wiring member with a support member and the attachment structure for a wiring member is not necessarily provided with the support members  90 ,  100 . One or both of the support members  90 ,  100  may be omitted. 
     In the wiring member  50 , only the connector C is provided on one side portion and only the attachment piece  76  is provided on the other side portion. However, the configuration does not need to be so. In one or both of the one side portion and the other side portion, the connector C and the attachment piece  76  may both be present. The connector C and the attachment piece  76  may both be present at a side portion corresponding to one of the support members  10 ,  90 ,  100 . The connector C and the attachment piece  76  may both be present at a side portion corresponding to the plurality of support members  10 ,  90 ,  100 . At both the one side portion and the other side portion, only the connector C may be provided. At both the one side portion and the other side portion, only the attachment piece  76  may be provided. 
     Note that the configurations described in the embodiment and the modified examples can be appropriately combined with one another in a non-contradictory manner.
