     DETAILED DESCRIPTION OF EMBODIMENTS 
     Description of Embodiments of Present Disclosure 
     First, embodiments of the present disclosure will be listed and described. 
     [1] The wire harness of the present disclosure includes: a wire harness main body including an electric wire member and an outer cover member enclosing an outer circumference of the electric wire member; a route-regulating member that is attached to an outer circumference of the outer cover member and regulates a route of the wire harness main body; and an attachment member attached to an outer circumference of a portion in a lengthwise direction of the route-regulating member, in which the route-regulating member includes a first main body portion that covers a portion of the outer circumference of the outer cover member, and an insertion port that is open in a direction orthogonal to a lengthwise direction of the first main body portion and extends along the entire length in the lengthwise direction of the first main body portion, the route-regulating member includes a connecting portion that is connected to the attachment member, the attachment member includes a covering portion that covers an outer circumference of the connecting portion, and the covering portion includes a regulating wall that is engageable with an end surface in the lengthwise direction of the route-regulating member in a lengthwise direction of the wire harness main body. 
     According to this configuration, the connecting portion of the route-regulating member and the covering portion of the attachment member are provided so as to overlap each other in the lengthwise direction of the wire harness main body. At this time, the covering portion is provided with the regulating wall that is engageable with the end surface in the lengthwise direction of the route-regulating member. Thus, by engaging the end surface in the lengthwise direction of the route-regulating member with the regulating wall, the route-regulating member can be easily positioned with respect to the attachment member when attaching the route-regulating member to the attachment member. As a result, it is possible to improve workability when attaching the route-regulating member to the attachment member. Accordingly, it is possible to make the wire harness easier to assemble. 
     [2] It is preferable that the covering portion is formed in a ring shape enclosing all the way around the outer circumference of the connecting portion and the outer circumference of the outer cover member at a portion to which the connecting portion is attached, and the covering portion includes a second main body portion that covers a portion of the outer circumference of the first main body portion and a lid portion that is coupled to the second main body portion. 
     According to this configuration, although the covering portion is ring-shaped, the covering portion is divided into the second main body portion and the lid portion, whereby the attachment member including the covering portion can be retrofitted to the route-regulating member and the outer cover member. It is possible to make the wire harness easier to assemble. 
     [3] It is preferable that the regulating wall includes a main-body-side regulating wall that protrudes from an inner surface of the second main body portion inward in a radial direction of the covering portion, and a lid-side regulating wall that protrudes from an inner surface of the lid portion inward in the radial direction of the covering portion. 
     According to this configuration, if the route-regulating member is first inserted into the second main body portion, the end surface in the lengthwise direction of the route-regulating member can be engaged with the main-body-side regulating wall. Also, if the route-regulating member is first inserted into the lid portion, the end surface in the lengthwise direction of the route-regulating member can be engaged with the lid-side regulating wall. As a result, regardless of whether the route-regulating member is first inserted into either the second main body portion or the lid portion, the route-regulating member can be easily positioned with respect to the attachment member. 
     [4] It is preferable that the second main body portion has a first accommodation port that is open in a direction orthogonal to a lengthwise direction of the second main body portion, and the main-body-side regulating wall is formed over the entire circumference of the second main body portion, in a circumferential direction of the covering portion, the main-body-side regulating wall has a second accommodation port that is open in a direction orthogonal to the lengthwise direction of the second main body portion and is in communication with the first accommodation port, an opening width of the second accommodation port is smaller than an opening width of the first accommodation port, and the opening width of the second accommodation port is smaller than an outer diameter of the route-regulating member. 
     According to this configuration, the opening width of the second accommodation port provided in the main-body-side regulating wall is smaller than the outer diameter of the route-regulating member. Thus, when the route-regulating member is inserted into the covering portion, the end surface in the lengthwise direction of the route-regulating member can be suitably engaged with the main-body-side regulating wall. As a result, the route-regulating member can be suitably positioned with respect to the attachment member. 
     [5] It is preferable that the route-regulating member includes a first end portion and a second end portion that are two end portions in a circumferential direction of the first main body portion and form the insertion port, the covering portion has a projecting portion that protrudes from an inner surface of the covering portion to the insertion port, and the projecting portion is able to come into contact with at least one of the first end portion and the second end portion in a circumferential direction of the route-regulating member. 
     According to this configuration, the projecting portion of the covering portion can come into contact with at least one of the first end portion and the second end portion forming the insertion port in the circumferential direction of the route-regulating member. For this reason, the projecting portion and the first end portion or the second end portion are engaged with each other in the circumferential direction of the route-regulating member. As a result, it is possible to suitably suppress rotation of the route-regulating member in the circumferential direction with respect to the covering portion. 
     [6] It is preferable that the outer cover member is a corrugated tube having an accordion structure in which a ring-shaped protrusion and a ring-shaped recess are alternatingly continuous with each other in a lengthwise direction of the outer cover member, and the projecting portion has a protrusion that enters the ring-shaped recess. 
     According to this configuration, the projecting portion has a protrusion that enters the ring-shaped recess of the corrugated tube. For this reason, it is possible to suppress movement of the corrugated tube with respect to the attachment member in the lengthwise direction of the corrugated tube. 
     [7] It is preferable that a fastening allowance is provided between an outer circumference of the route-regulating member and an inner circumference of the covering portion. 
     According to this configuration, the route-regulating member is fitted to the inner circumference of the covering portion with the fastening allowance interposed therebetween. That is, when the route-regulating member is fitted into the covering portion, the outer circumferential surface of the route-regulating member and the inner circumferential surface of the covering portion are brought into contact with each other in a state in which the fastening allowance is present therebetween. As a result, the route-regulating member fitted into the covering portion is held in a state of being constantly pressed inward in the radial direction of the covering portion by the inner surface of the covering portion. Therefore, rattling of the route-regulating member in the covering portion can be suppressed. Also, relative movement of the route-regulating member with respect to the covering portion is suitably suppressed in the lengthwise direction of the wire harness main body. For this reason, it is possible to suitably suppress positional misalignment of the route-regulating member with respect to the covering portion in the lengthwise direction of the wire harness main body, and to suitably suppress detachment of the route-regulating member from the covering portion. 
     [8] It is preferable that, when the route-regulating member is a first route-regulating member, the attachment member is a second route-regulating member that is attached to the outer circumference of the outer cover member and has a route-regulating portion that regulates the route of the wire harness main body, the connecting portion is provided at an end portion in the lengthwise direction of the first route-regulating member, the second route-regulating member is formed such that the covering portion and the route-regulating portion are continuous with each other in the lengthwise direction of the wire harness main body, the covering portion is provided at an end portion in a lengthwise direction of the second route-regulating member, and the regulating wall is provided at an end portion that is connected to the route-regulating portion, out of the two end portions in a lengthwise direction of the covering portion. 
     According to this configuration, the regulating wall is provided at the end portion that is connected to the route-regulating portion, out of the two end portions in the lengthwise direction of the covering portion. This regulating wall regulates the amount by which the first route-regulating member is inserted into the second route-regulating member in the lengthwise direction of the wire harness main body. Thus, it is possible to inhibit the first route-regulating member from being inserted to the route-regulating portion of the second route-regulating member in the lengthwise direction of the wire harness main body. 
     [9] It is preferable that the first route-regulating member regulates the route of a straight section, which is a section having a linear shape in the route of the wire harness main body, and the second route-regulating member regulates the route of a bent section, which is a section that is bent in the route of the wire harness main body. 
     According to this configuration, the route of the straight section is regulated by the first route-regulating member, and the route of the bent section is regulated by the second route-regulating member. As a result, it is possible to prevent the route of the straight section and the route of the bent section from deviating from the desired routes.

Also, “opposing” in the present specification means that faces or members are at positions in front of each other, and includes not only a case where they are completely in front of each other but also a case of being at positions where they are partially in front of each other. Also, the term “opposing” in the present specification includes both the case where a member different from two portions is interposed between the two portions and the case where nothing is interposed between the two portions. Note that the present disclosure is not limited to these examples, and is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. 
     Overall Configuration of Wire Harness  10   
     A wire harness  10  shown in  FIG.  1    is to be mounted in a vehicle V such as a hybrid vehicle or an electric vehicle, for example. The wire harness  10  electrically connects two or more on-board devices to each other. The on-board devices are electric devices mounted in the vehicle V. The wire harness  10  electrically connects, for example, an inverter M 1  that is installed in a front portion of the vehicle V and a high-voltage battery M 2  that is installed rearward of the inverter M 1  in the vehicle V, to each other. The wire harness  10  has an elongated shape that extends in a front-rear direction of the vehicle V, for example. The wire harness  10  is routed in the vehicle V so that, for example, an intermediate portion in the lengthwise direction of the wire harness  10  passes outside the vehicle interior such as under the floor of the vehicle V. 
     The inverter M 1  is, for example, connected to a motor (not shown) for driving wheels, which serves as a power source when the vehicle travels. The inverter M 1  generates AC power from the DC power of the high-voltage battery M 2 , and supplies the AC power to the motor. The high-voltage battery M 2  is, for example, a battery that is capable of supplying a voltage of several hundred volts. 
     The wire harness  10  includes a wire harness main body  11 . The wire harness main body  11  includes an electric wire member  20  (electric wire) and a tubular outer cover member  30  (outer cover) that encloses the outer circumference of the electric wire member  20 . The wire harness  10  has connectors C 1  and C 2  that are respectively attached to two end portions of the electric wire member  20 . One end portion in the lengthwise direction of the electric wire member  20  is connected to the inverter M 1  via the connector C 1 , and the other end portion in the lengthwise direction of the electric wire member  20  is connected to the high-voltage battery M 2  via the connector C 2 . 
     As shown in  FIGS.  2  and  3   , the wire harness  10  includes a first route-regulating member  40  (first route-regulating cover) that is attached to the outer circumference of the outer cover member  30  and a second route-regulating member  50  (second route-regulating cover) that is attached to the outer circumference of the outer cover member  30 . The first route-regulating member  40  and the second route-regulating member  50  regulate the route along which the wire harness main body  11  is routed. Note that the first route-regulating member  40  and the second route-regulating member  50  are omitted from  FIG.  1   . 
     Configuration of Electric Wire Member  20   
     As shown in  FIGS.  3  and  4   , for example, the electric wire member  20  includes one or more electric wires  21  (two in the present embodiment) and a braided member  25  that collectively encloses the outer circumferences of the plurality of electric wires  21 . 
     As shown in  FIG.  4   , each electric wire  21  is a coated electric wire that includes a conductive core wire  22  and an insulating coating  23  that encloses the outer circumference of the core wire  22  and has insulating properties. Each electric wire  21  is, for example, a high-voltage electric wire that supports a high voltage and a large current. Each electric wire  21  may be, for example, a non-shielded electric wire that does not include an electromagnetic shield structure, or a shielded electric wire that includes an electromagnetic shield structure. Each electric wire  21  in the present embodiment is a non-shielded electric wire. 
     As the core wire  22 , a stranded wire that is constituted by a plurality of metal strands twisted together, a single core wire that is constituted by a single conductor, or the like may be used, for example. As the single core wire, a columnar conductor that is constituted by one columnar metal rod with a solid internal structure, a tubular conductor with a hollow internal structure, or the like may be used, for example. As the core wire  22 , a combination of a stranded wire, a columnar conductor, or a tubular conductor may be used. As the material of the core wire  22 , a metal material such as a copper-based material or an aluminium-based material may be used, for example. 
     The insulating coating  23  covers, for example, all the way around the outer circumferential surface of the core wire  22 . The insulating coating  23  is constituted by, for example, a resin material that has insulating properties. 
     The cross-sectional shape of each wire  21  cut along a plane that is orthogonal to the lengthwise direction of each wire  21 , that is, the transverse cross-sectional shape of each wire  21 , may be any shape. The transverse cross-sectional shape of each electric wire  21  may be, for example, a circular shape, a semi-circular shape, a polygonal shape, a square shape, a flat shape, or the like. The transverse cross-sectional shape of each electric wire  21  in the present embodiment is a circular shape. 
     The braided member  25  has, for example, an overall tubular shape that collectively encloses the outer circumferences of the plurality of electric wires  21 . As the braided member  25 , a braided wire in which a plurality of metal strands are braided or a braided wire in which metal strands and resin strands are braided in combination with each other may be used, for example. As the material of the metal strands, a metal material such as a copper-based material or an aluminium-based material may be used, for example. Although not shown in the drawings, the two end portions of the braided member  25  in the lengthwise direction are grounded at, for example, the connectors C 1  and C 2  (see  FIG.  1   ). 
     Configuration of Outer Cover Member  30   
     As shown in  FIG.  3   , the outer cover member  30  has a tubular shape that encloses all the way around the outer circumference of the electric wire member  20 . The outer cover member  30  in the present embodiment is formed in a cylindrical shape. The outer cover member  30  is, for example, provided with a circumferential wall that is formed so as to be continuous all the way around the circumferential surface of the outer cover member  30 . The outer cover member  30  is, for example, sealed all the way around the circumferential surface of the outer cover member  30 . The outer cover member  30  has, for example, a function of protecting the electric wire member  20  from flying objects and water droplets. 
     The outer cover member  30  is, for example, flexible and is easily bendable. Examples of the flexible outer cover member  30  include a resin corrugated tube and a rubber waterproof cover. The outer cover member  30  of the present embodiment is a resin corrugated tube having an accordion structure in which ring-shaped protrusions  31  and ring-shaped recesses  32  are provided alternatingly and continuously along the lengthwise direction of the outer cover member  30 . Each of the ring-shaped protrusions  31  and the ring-shaped recesses  32  has, for example, a ring shape that encircles the outer cover member  30  once in the circumferential direction. As the material of the outer cover member  30 , for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin can be used. Note that in  FIGS.  1  and  2   , the outer cover member  30  is shown simplified for the sake of simplification of the drawings. 
     Configuration of First Route-Regulating Member  40  and Second Route-Regulating Member  50   
     As shown in  FIG.  2   , each of the first route-regulating member  40  and the second route-regulating member  50  holds the outer cover member  30 . Each of the first route-regulating member  40  and the second route-regulating member  50  is harder than, for example, the outer cover member  30 . Each of the first route-regulating member  40  and the second route-regulating member  50  has a hardness that makes it more difficult to bend in a direction orthogonal to the lengthwise direction of the wire harness main body  11  compared to the outer cover member  30 . As a result, the first route-regulating member  40  and the second route-regulating member  50  regulate the route of the wire harness main body  11 . For example, the first route-regulating member  40  and the second route-regulating member  50  assist the outer cover member  30  so that the wire harness main body  11  does not deviate from the desired route as a result of bending under its own weight or the like. The outer cover member  30  is less likely to bend than, for example, in a state where the first route-regulating member  40  and the second route-regulating member  50  are not attached. 
     The first route-regulating member  40  is provided along a portion in the lengthwise direction of the wire harness main body  11 . For example, the first route-regulating member  40  is attached to the outer circumference of the outer cover member  30  along a straight section  11 A, which is a straight section of the route of the wire harness main body  11 . The first route-regulating member  40  regulates the route of the wire harness main body  11  in the straight section  11 A. Here, the straight section  11 A is a section in which the route of the wire harness main body  11  extends linearly in one direction. Note that one or more first route-regulating members  40  are provided depending on the route of the wire harness main body  11 . 
     The second route-regulating member  50  is provided along a portion in the lengthwise direction of the wire harness main body  11 . For example, the second route-regulating member  50  is attached to the outer circumference of the outer cover member  30  along a bent section  11 B, which is a bent section of the route of the wire harness main body  11 . The second route-regulating member  50  regulates the route of the wire harness main body  11  in the bent section  11 B. Here, the bent section  11 B is a section in which the route of the wire harness main body  11  is bent two-dimensionally or three-dimensionally. Note that one or more second route-regulating members  50  may be provided depending on the route of the wire harness main body  11 . 
     Configuration of First Route-Regulating Member  40   
     As shown in  FIG.  4   , the first route-regulating member  40  covers part of the outer circumference of the outer cover member  30  in the circumferential direction of the outer cover member  30 . The first route-regulating member  40  has a tubular shape that covers the outer circumference of the outer cover member  30  in a portion in the circumferential direction of the outer cover member  30 . The transverse cross-sectional shape of the first route-regulating member  40  is C-shaped overall. The first route-regulating member  40  covers, for example, a range larger than half of the outer circumference of the outer cover member  30 . The transverse cross-sectional shape of the first route-regulating member  40  is, for example, uniform over the entire length in the lengthwise direction of the first route-regulating member  40 . As shown in  FIG.  2   , the first route-regulating member  40  extends along the route of the straight section  11 A, and is formed in a shape extending linearly in one direction, for example. 
     The first route-regulating member  40  is made of metal or resin, for example. The first route-regulating member  40  in the present embodiment is made of resin. As the material of the first route-regulating member  40 , a synthetic resin such as polypropylene, polyamide, or polyacetal may be used, for example. The first route-regulating member  40  may be manufactured using a well-known manufacturing method such as extrusion molding or injection molding, for example. 
     As shown in  FIG.  3   , the first route-regulating member  40  has a first main body portion  41  (first main body) that covers part of the outer circumference of the outer cover member  30 , and an insertion port  42  that is open in a direction orthogonal to the lengthwise direction of the first main body portion  41 . The first route-regulating member  40  has a first end portion  43  and a second end portion  44  which are both ends in the circumferential direction of the first main body portion  41  and form the insertion port  42 . 
     As shown in  FIG.  4   , the first main body portion  41  forms the main part of the first route-regulating member  40 . The thickness in the radial direction of the first main body portion  41  is, for example, uniform in the circumferential direction of the first route-regulating member  40 . The transverse cross-sectional shape of the first main body portion  41  is formed, for example, in a shape that extends along the outer surface of the outer cover member  30 . The transverse cross-sectional shape of the first main body portion  41  is formed, for example, in an arc shape. 
     The first end portion  43  and the second end portion  44  are provided on mutually opposite sides in the circumferential direction of the first main body portion  41 . The first end portion  43  and the second end portion  44  are provided spaced apart from each other with the insertion port  42  interposed therebetween in the circumferential direction of the first main body portion  41 . In other words, the gap between the first end portion  43  and the second end portion  44  in the circumferential direction of the first route-regulating member  40  forms the insertion port  42 . As described above, the first route-regulating member  40  is formed in a C shape having the insertion port  42  in a portion in the circumferential direction of the first main body portion  41 . 
     The opening width of the insertion port  42 , that is, the shortest distance between the first end portion  43  and the second end portion  44  is smaller than, for example, the outer diameter of the outer cover member  30 . As shown in  FIG.  3   , the insertion port  42  extends along the lengthwise direction of the first main body portion  41  over the entire length in the lengthwise direction of the first main body portion  41 . That is, the insertion port  42  is formed so as to be open in a direction orthogonal to the lengthwise direction of the first main body portion  41  and to be open at both ends in the lengthwise direction of the first main body portion  41 . 
     In response to the outer cover member  30  being inserted into the insertion port  42  from a direction orthogonal to the lengthwise direction of the first route-regulating member  40 , the first route-regulating member  40  is elastically deformed and the opening width of the insertion port  42  increases. Once the outer cover member  30  has been inserted into the first route-regulating member  40 , the first route-regulating member  40  elastically returns to return to its original shape. As a result, the opening width of the insertion port  42  becomes smaller than the outer diameter of the outer cover member  30 , and therefore the first route-regulating member  40  is attached to the outer circumference of the outer cover member  30 . 
     Note that, in a state in which the outer cover member  30  is inserted into the first route-regulating member  40 , the opening width of the insertion port  42  does not always return to its original width, that is, the width thereof when the outer cover member  30  is not inserted. Specifically, there are cases where elastic deformation of the first main body portion  41  to return to its original shape is inhibited by the outer cover member  30 , and thus the opening width of the insertion port  42  is slightly larger than its original width. There are also cases where, when the outer cover member  30  is bent due to being pressed by the first route-regulating member  40  in a state in which the outer cover member  30  is inserted into the first route-regulating member  40 , the opening width of the insertion port  42  returns to its original width. That is, the opening width of the insertion port  42  in a state in which the outer cover member  30  is inserted into the first route-regulating member  40  is a distance that is based on the rigidity, flexibility, and the like of the outer cover member  30  and the first route-regulating member  40 . 
     As shown in  FIG.  4   , the first end portion  43  has a leading end  43 A. The second end portion  44  has a leading end  44 A. The leading ends  43 A and  44 A form the insertion port  42 . The leading ends  43 A and  44 A are formed in a curved shape when viewed from the lengthwise direction of the first route-regulating member  40 . That is, the transverse cross-sectional shapes of the leading ends  43 A and  44 A are formed in curved shapes. 
     The first route-regulating member  40  has, for example, protruding portions  45  that protrude from the inner surfaces of the first end portion  43  and the second end portion  44 . Each protruding portion  45  protrudes toward the outer cover member  30  inserted into the first route-regulating member  40  and can come into contact with the outer surface of the outer cover member  30 . The protruding portions  45  come into contact with, for example, the outer surfaces of the ring-shaped protrusions  31  of the outer cover member  30 . The two protruding portions  45  protrude from the inner surfaces of the leading ends  43 A and  44 A, for example. The transverse cross-sectional shape of each protruding portion  45  is formed, for example, into a curved shape. The transverse cross-sectional shape of each protruding portion  45  of the present embodiment is formed in a semi-circular shape. Each protruding portion  45  extends, for example, along the lengthwise direction of the first route-regulating member  40  over the entire length in the lengthwise direction of the first route-regulating member  40 . 
     Each protruding portion  45  presses the outer cover member  30  from the outer side of the outer cover member  30 , for example. The outer cover member  30  is elastically sandwiched by the two protruding portions  45  and the first main body portion  41 . As a result, the connection of the first route-regulating member  40  to the outer cover member  30  is strengthened. Accordingly, the first route-regulating member  40  attached to the outer circumference of the outer cover member  30  is suppressed from moving in the lengthwise direction of the outer cover member  30 . 
     As shown in  FIG.  3   , the first route-regulating member  40  has a connecting portion  47  (connection) that is to be connected to the second route-regulating member  50 . The connecting portion  47  is provided, for example, at one end portion in the lengthwise direction of the first route-regulating member  40 . The connecting portion  47  has an end surface  47 A in the lengthwise direction of the first route-regulating member  40 . 
     Configuration of Second Route-Regulating Member  50   
     As shown in  FIG.  2   , the second route-regulating member  50  is attached to the outer circumference of the outer cover member  30  in the bent section  11 B. The second route-regulating member  50  is bent along the shape of the bent section  11 B. The second route-regulating member  50  is made of, for example, metal or resin. The second route-regulating member  50  of the present embodiment is made of resin. As the material of the second route-regulating member  50 , for example, a synthetic resin such as polypropylene, polyamide, or polyacetal can be used. The second route-regulating member  50  can be manufactured using a known manufacturing method such as injection molding. 
     The second route-regulating member  50  has a covering portion  51  (cover) that covers a portion in the lengthwise direction of the first route-regulating member  40 , and a route-regulating portion  70  that is attached to the outer circumference of the outer cover member  30 . In the second route-regulating member  50 , the covering portion  51  and the route-regulating portion  70  are continuous with each other in the lengthwise direction of the wire harness main body  11 , for example. The second route-regulating member  50  is, for example, a single component in which the covering portion  51  and the route-regulating portion  70  are formed in one piece. The covering portion  51  is provided, for example, at one end portion in the lengthwise direction of the second route-regulating member  50 . The covering portion  51  has a second main body portion  52  (second main body) and a lid portion  56  (lid) that is coupled to the second main body portion  52 . The route-regulating portion  70  has a third main body portion  71 . The third main body portion  71  is formed in one piece continuous with the second main body portion  52 . 
     Configuration of Covering Portion  51   
     As shown in  FIG.  2   , the covering portion  51  is provided, for example, so as to overlap the connecting portion  47  in the radial direction of the outer cover member  30 . That is, in the wire harness  10 , one end portion in the lengthwise direction of the first route-regulating member  40  and one end portion in the lengthwise direction of the second route-regulating member  50  are provided so as to overlap each other in the lengthwise direction of the wire harness main body  11 . 
     The covering portion  51  encloses, for example, the outer circumference of the connecting portion  47  of the first route-regulating member  40 . The covering portion  51  is formed, for example, in a ring shape that encloses all the way around the connecting portion  47  and the outer cover member  30  at the portion to which the connecting portion  47  is attached to the outer cover member  30 . The covering portion  51  extends, for example, along the route of the straight section  11 A, and is formed in a shape extending linearly in one direction. 
     As shown in  FIG.  4   , the second main body portion  52  covers, for example, a portion of the outer circumference of the outer cover member  30  in the circumferential direction of the outer cover member  30 . The second main body portion  52  covers, for example, a portion of the outer circumference of the first route-regulating member  40  in the circumferential direction of the first route-regulating member  40 . The second main body portion  52  has a tubular shape that covers the outer circumference of the first route-regulating member  40  at a portion in the circumferential direction of the first route-regulating member  40 . The second main body portion  52  covers, for example, the outer circumference of the first main body portion  41  of the first route-regulating member  40 . The second main body portion  52  covers, for example, a range larger than half of the outer circumference of the first main body portion  41 . The transverse cross-sectional shape of the inner surface of the second main body portion  52  is formed, for example, in a shape corresponding to the outer surface of the first main body portion  41 . The transverse cross-sectional shape of the inner surface of the second main body portion  52  is formed, for example, into a curved shape. The transverse cross-sectional shape of the inner surface of the second main body portion  52  is U-shaped overall. 
     The second main body portion  52  has a third end portion  53  and a fourth end portion  54 , which are the two ends in the circumferential direction of the second main body portion  52 . The second main body portion  52  has a first accommodation port  55  that is formed by the third end portion  53  and the fourth end portion  54 . The first accommodation port  55  is an opening between the third end portion  53  and the fourth end portion  54 . As shown in  FIG.  3   , the first accommodation port  55  is open in a direction orthogonal to the lengthwise direction of the second main body portion  52 . The first accommodation port  55  extends along the lengthwise direction of the second main body portion  52 , over the entire length in the lengthwise direction of the second main body portion  52 . The opening width of the first accommodation port  55 , that is, the shortest distance between the third end portion  53  and the fourth end portion  54  is, for example, equal to the outer diameter of the first route-regulating member  40 , or is greater than the outer diameter of the first route-regulating member  40 . The outer cover member  30  and the first route-regulating member  40  are inserted into the first accommodation port  55  along a direction orthogonal to the lengthwise direction of the second route-regulating member  50 . 
     The lid portion  56  is formed in one piece with, for example, the second main body portion  52 . The transverse cross-sectional shape of the inner surface of the lid portion  56  is formed, for example, in a shape corresponding to the outer surface of the outer cover member  30 . The transverse cross-sectional shape of the inner surface of the lid portion  56  is formed, for example, in a shape corresponding to the outer surface of the first route-regulating member  40 . The transverse cross-sectional shape of the inner surface of the lid portion  56  is formed, for example, in an elliptical arc shape or an ovoid arc shape. The lid portion  56  is formed, for example, in the shape of a substantially semi-elliptical cylinder. Here, “oval” in the present specification is a shape consisting of two parallel lines having substantially equal lengths and two semi-circles. 
     The lid portion  56  covers the first accommodation port  55  of the second main body portion  52 . The lid portion  56  covers the first accommodation port  55 , for example, only in the covering portion  51  in the lengthwise direction of the second route-regulating member  50 . In other words, the lid portion  56  is only provided in the covering portion  51  of the second route-regulating member  50 , and is not provided on the route-regulating portion  70 . 
     The covering portion  51  has, for example, a hinge portion  57  that connects the second main body portion  52  and the lid portion  56 . The hinge portion  57  connects one end in the circumferential direction (here, the third end portion  53 ) of the second main body portion  52  and one end in the circumferential direction of the lid portion  56 . One or more (in this embodiment, two) lock portions  58  are provided at the other end in the circumferential direction (here, the fourth end portion  54 ) of the second main body portion  52 . One or more (in this embodiment, two) claw portions  59  are provided at the other end in the circumferential direction of the lid portion  56 . 
     The second main body portion  52  and the lid portion  56  are relatively rotatable about the hinge portion  57 . The lid portion  56  is rotatable between an open position shown in  FIG.  3    and a closed position shown in  FIG.  2   , using the hinge portion  57  as an axis. As shown in  FIG.  4   , the claw portions  59  latch onto the lock portions  58  when the lid portion  56  is in the closed position. As a result, the lid portion  56  is held in the closed position. In this manner, the second main body portion  52  and the lid portion  56  are coupled to each other. In a state where the second main body portion  52  and the lid portion  56  are coupled to each other, the covering portion  51  forms a ring shape that collectively encloses the outer circumferences of the outer cover member  30  and the connecting portion  47 . The lid portion  56  covers the first accommodation port  55  of the second main body portion  52  in the closed position. The lid portion  56  covers the insertion port  42  at the connecting portion  47 , for example, in the closed position. 
     In this embodiment, the inner surface of the lid portion  56  does not come in contact with the outer surface of the first route-regulating member  40  while the lid portion  56  is located at a closed position. That is, a gap is formed between the inner surface of the lid portion  56  and the outer surface of the first route-regulating member  40 . This gap is formed over the entire length of the covering portion  51  in the lengthwise direction thereof, for example. 
     As shown in  FIG.  3   , the covering portion  51  has, for example, a regulating wall  60  that can engage with the end surface  47 A in the lengthwise direction of the first route-regulating member  40  in the lengthwise direction of the wire harness main body  11 . The regulating wall  60  protrudes, for example, inward in the radial direction of the covering portion  51  from the inner surface of the covering portion  51 . The regulating wall  60  extends, for example, along the circumferential direction of the covering portion  51 . The regulating wall  60  extends, for example, all the way around the circumferential surface of the covering portion  51 . The regulating wall  60  is provided at one end in the lengthwise direction of the covering portion  51 . 
     The regulating wall  60  has, for example, a main-body-side regulating wall  61  formed on the inner surface of the second main body portion  52 , and a lid-side regulating wall  62  formed on the inner surface of the lid portion  56 . The main-body-side regulating wall  61  and the lid-side regulating wall  62  are provided, for example, at the same position as each other in the lengthwise direction of the wire harness main body  11 . 
     As shown in  FIG.  5   , the main-body-side regulating wall  61  protrudes inward in the radial direction from the inner surface of the second main body portion  52 . The main-body-side regulating wall  61  extends over the entire circumference of the second main body portion  52 , for example, in the circumferential direction of the covering portion  51 . The transverse cross-sectional shape of the inner surface of the main-body-side regulating wall  61  is formed in the same shape as the transverse cross-sectional shape of the inner surface of the second main body portion  52 . The transverse cross-sectional shape of the inner surface of the main-body-side regulating wall  61  of the present embodiment is formed in a U shape. The transverse cross-sectional shape of the inner surface of the main-body-side regulating wall  61  is formed to be one size smaller than the transverse cross-sectional shape of the inner surface of the second main body portion  52 , for example. Note that the electric wire member  20  is not shown in  FIG.  5   . 
     The main-body-side regulating wall  61  has a second accommodation port  63  that is open in a direction orthogonal to the lengthwise direction of the second main body portion  52 . The second accommodation port  63  is in communication with the first accommodation port  55 . The first accommodation port  55  and the second accommodation port  63  extend over the entire length in the lengthwise direction of the second main body portion  52 . The opening width of the second accommodation port  63  is smaller than the opening width of the first accommodation port  55 . The opening width of the second accommodation port  63  is smaller than, for example, the outer diameter of the first route-regulating member  40 . 
     As shown in  FIG.  3   , the main-body-side regulating wall  61  is provided, for example, at the end portion connected to the third main body portion  71  out of the two ends in the lengthwise direction of the second main body portion  52 . The main-body-side regulating wall  61  extends, for example, along the lengthwise direction of the wire harness main body  11 . The main-body-side regulating wall  61  extends from the end portion of the second main body portion  52 , for example, over the entire length in the lengthwise direction of the third main body portion  71 . For example, a level difference is formed by the main-body-side regulating wall  61  at the boundary portion between the inner surface of the second main body portion  52  and the inner surface of the third main body portion  71 . 
     As shown in  FIG.  6   , an end surface  61 A in the lengthwise direction of the main-body-side regulating wall  61  opposes, for example, the first main body portion  41  of the first route-regulating member  40  in the lengthwise direction of the wire harness main body  11  and can come into contact with the first main body portion  41 . The end surface  61 A of the main-body-side regulating wall  61  opposes, for example, the end surface  47 A in the lengthwise direction of the first route-regulating member  40  in the lengthwise direction of the wire harness main body  11 , and can come into contact with the end surface  47 A. 
     As shown in  FIG.  5   , the lid-side regulating wall  62  protrudes inward in the radial direction from the inner surface of the lid portion  56 . The lid-side regulating wall  62  extends over the entire circumference of the lid portion  56 , for example, in the circumferential direction of the covering portion  51 . The transverse cross-sectional shape of the inner surface of the lid-side regulating wall  62  is formed, for example, in a shape corresponding to the outer surface of the first route-regulating member  40 . The transverse cross-sectional shape of the inner surface of the lid-side regulating wall  62  is formed, for example, in an arc shape or an elliptical arc shape. The transverse cross-sectional shape of the inner surface of the lid-side regulating wall  62  of the present embodiment is formed in a semi-elliptical arc shape. 
     The lid-side regulating wall  62  opposes, for example, the first end portion  43  and the second end portion  44  of the first route-regulating member  40  in the lengthwise direction of the wire harness main body  11  (see  FIG.  3   ), and can come into contact with the first end portion  43  and the second end portion  44 . 
     As shown in  FIG.  3   , the regulating wall  60  composed of the main-body-side regulating wall  61  and the lid-side regulating wall  62  comes into contact with the end surface  47 A in the lengthwise direction of the first route-regulating member  40 , whereby movement of the first route-regulating member  40  in the lengthwise direction of the wire harness main body  11  is regulated. For example, the regulating wall  60  regulates the movement of the first route-regulating member  40  so that the first route-regulating member  40  is not inserted into the route-regulating portion  70 . 
     As shown in  FIG.  4   , the covering portion  51  has, for example, a projecting portion  65  (projection). The projecting portion  65  protrudes from the inner surface of the covering portion  51  toward the insertion port  42  of the first route-regulating member  40  inserted into the covering portion  51 . The projecting portion  65  protrudes so as to be located inside the insertion port  42 . The projecting portion  65  can come into contact with the first end portion  43  and the second end portion  44  in the circumferential direction of the first route-regulating member  40 . 
     The projecting portion  65  is provided on the inner surface of the lid portion  56 , for example. The projecting portion  65  protrudes from the inner surface of the lid portion  56  toward the first accommodation port  55 , for example. For this reason, in a state where the projecting portion  65  is located inside the insertion port  42 , the insertion port  42  faces the lid portion  56  side of the covering portion  51 . 
     As shown in  FIG.  3   , the projecting portion  65  extends, for example, along the lengthwise direction of the wire harness body  11 . The projecting portion  65  extends, for example, along the lengthwise direction of the covering portion  51  over the entire length of the covering portion  51  in the lengthwise direction. The projecting portion  65  is partially provided, for example, in the circumferential direction of the lid portion  56 . The projecting portion  65  is provided, for example, in an intermediate portion in the circumferential direction of the lid portion  56 . A portion of the projecting portion  65  constitutes, for example, a lid-side regulating wall  62 . For example, the projecting portion  65  provided at one end portion in the lengthwise direction of the covering portion  51  constitutes the lid-side regulating wall  62 . 
     As shown in  FIG.  6   , the projecting portion  65  has, for example, a protrusion  66  that enters a ring-shaped recess  32  of the outer cover member  30 . The protrusion  66  is provided so as to further protrude from the protruding leading end surface of the projecting portion  65 . A plurality of protrusions  66  are provided in the lengthwise direction of the wire harness main body  11 . In the present embodiment, four protrusions  66  are provided in the lengthwise direction of the wire harness main body  11 , and each of the protrusions  66  is inserted into a different ring-shaped recess  32 . 
     Configuration of Route-Regulating Portion  70   
     As shown in  FIG.  2   , the third main body portion  71  of the route-regulating portion  70  extends along the route of the bent section  11 B, for example. That is, the third main body portion  71  has a bent shape that follows the shape of the bent section  11 B. The third main body  71  covers, for example, a portion of the outer circumference of the outer cover member  30  in the circumferential direction of the outer cover member  30 . The third main body portion  71  has a tubular shape that covers the outer circumference of the outer cover member  30  in a portion in the circumferential direction of the outer cover member  30 . The third main body portion  71  covers, for example, a range larger than half of the outer circumference of the outer cover member  30 . The transverse cross-sectional shape of the inner surface of the third main body portion  71  is formed in a shape corresponding to the outer surface of the outer cover member  30 , for example. The transverse cross-sectional shape of the inner surface of the third main body  71  is formed, for example, in a curved shape. The transverse cross-sectional shape of the inner surface of the third main body portion  71  is U-shaped overall. 
     The third main body portion  71  has a second accommodation port  63  that is open in a direction orthogonal to the lengthwise direction of the third main body portion  71 . The second accommodation port  63  extends along the lengthwise direction of the third main body portion  71  over the entire length in the lengthwise direction of the third main body portion  71 . The second accommodation port  63  is in communication with the first accommodation port  55 . The accommodation port constituted by the first accommodation port  55  and the second accommodation port  63  extends along the lengthwise direction of the second route-regulating member  50  over the entire length in the lengthwise direction of the second route-regulating member  50 . That is, the accommodation port constituted by the first accommodation port  55  and the second accommodation port  63  is open in a direction orthogonal to the lengthwise direction of the second route-regulating member  50 , and is open at both ends in the lengthwise direction of the second route-regulating member  50 . 
     The opening width of the second accommodation port  63  is, for example, equal to the outer diameter of the outer cover member  30  or larger than the outer diameter of the outer cover member  30 . The outer cover member  30  is inserted into the second accommodation port  63  along a direction orthogonal to the lengthwise direction of the second route-regulating member  50 . Note that the first route-regulating member  40  is not inserted into the third main body  71 . 
     Configuration of Fixing Members  81  and  82   
     The wire harness  10  has, for example, a fixing member  81  for fixing the first route-regulating member  40  to the outer circumference of the outer cover member  30 . The wire harness  10  has, for example, a fixing member  82  for fixing the second route-regulating member  50  to the outer circumference of the outer cover member  30 . As the fixing members  81  and  82 , for example, cable ties made of resin or metal, crimp rings, adhesive tape, or the like can be used. The fixing members  81  and  82  of this embodiment are adhesive tape. 
     The fixing member  81  is formed so as to fix, for example, the end portion provided opposite to the connecting portion  47  out of the end portions in the lengthwise direction of the first route-regulating member  40  to the outer surface of the outer cover member  30 . The fixing member  81  is wound, for example, from the outer surface of the end portion in the lengthwise direction of the first route-regulating member  40  onto the outer surface of the outer cover member  30 . As a result, it is possible to suppress movement of the first route-regulating member  40  with respect to the outer cover member  30  in the lengthwise direction and the circumferential direction of the wire harness main body  11 . The fixing member  82  is formed so as to fix, for example, the end portion provided opposite to the covering portion  51  out of the end portions in the lengthwise direction of the second route-regulating member  50  to the outer surface of the outer cover member  30 . The fixing member  82  is wound, for example, from the outer surface of the end portion in the lengthwise direction of the second route-regulating member  50  onto the outer surface of the outer cover member  30 . As a result, it is possible to suppress movement of the second route-regulating member  50  with respect to the outer cover member  30  in the lengthwise direction and the circumferential direction of the wire harness main body  11 . 
     Next, operation of this embodiment will be described. 
     In the lengthwise direction of the wire harness main body  11 , the connecting portion  47  of the first route-regulating member  40  and the covering portion  51  of the second route-regulating member  50  are provided so as to overlap each other. At this time, the covering portion  51  is provided with a regulating wall  60  that is engageable with the end surface  47 A in the lengthwise direction of the first route-regulating member  40 . Thus, by engaging the end surface  47 A with the regulating wall  60 , the first route-regulating member  40  can be easily positioned with respect to the second route-regulating member  50  when attaching the first route-regulating member  40  to the second route-regulating member  50 . 
     Next, effects of this embodiment will be described. 
     (1) The covering portion  51  of the second route-regulating member  50  is provided with the regulating wall  60  that is engageable with the end surface  47 A in the lengthwise direction of the first route-regulating member  40 . According to this configuration, by engaging the end surface  47 A with the regulating wall  60 , the first route-regulating member  40  can be easily positioned with respect to the second route-regulating member  50  when attaching the first route-regulating member  40  to the second route-regulating member  50 . As a result, it is possible to improve workability when attaching the first route-regulating member  40  to the second route-regulating member  50 . Accordingly, it is possible to make the wire harness  10  easier to assemble. 
     (2) Also, because the end surface  47 A is engaged with the regulating wall  60 , relative movement of the first route-regulating member  40  with respect to the second route-regulating member  50  is suppressed in the lengthwise direction of the wire harness main body  11 . Thus, it is possible to suppress positional misalignment of the first route-regulating member  40  with respect to the second route-regulating member  50  in the lengthwise direction of the wire harness main body  11 . As a result, the positional accuracy of the first route-regulating member  40  with respect to the second route-regulating member  50  can be improved. Here, in this embodiment, the second route-regulating member  50  is fixed to the outer cover member  30  of the wire harness main body  11  by the fixing member  82 . Thus, movement of the second route-regulating member  50  with respect to the wire harness main body  11  is suppressed in the lengthwise direction of the wire harness main body  11 . Thus, the positional accuracy of the first route-regulating member  40  with respect to the wire harness main body  11  can be improved by improving the positional accuracy of the first route-regulating member  40  with respect to the second route-regulating member  50 . As a result, the first route-regulating member  40  can be suitably arranged at a desired position of the wire harness main body  11 , here the straight section  11 A and the route of the straight section  11 A can be suitably regulated by the first route-regulating member  40 . In other words, it is possible to suitably suppress deviation of the installation position of the first route-regulating member  40  with respect to the wire harness main body  11  from the straight section  11 A. 
     (3) The insertion port  42  of the first route-regulating member  40  is open in a direction orthogonal to the lengthwise direction of the first route-regulating member  40  and extends along the entire length in the lengthwise direction of the first route-regulating member  40 . This makes it possible to attach the first route-regulating member  40  from the insertion port  42  to the outer cover member  30  after performing terminal processing such as attaching connectors C 1  and C 2  to the end portions in the lengthwise direction of the electric wire members  20 . In this manner, since the first route-regulating member  40  can be retrofitted, it is possible to make the wire harness  10  more easy to assemble. 
     (4) The covering portion  51  is formed in a ring shape that collectively encloses the connecting portion  47  and the outer cover member  30 . The covering portion  51  has the second main body portion  52  that covers a portion of the outer circumference of the first main body portion  41 , and the lid portion  56  that is coupled to the second main body portion  52 . According to this configuration, the second route-regulating member  50  including the covering portion  51  can be retrofitted to the first route-regulating member  40  and the outer cover member  30  due to the covering portion  51  having a ring shape enclosing the connecting portion  47  and the outer cover member  30  while the covering portion  51  is divided into the second main body portion  52  and the lid portion  56 . As a result, it is possible to make the wire harness  10  much easier to assemble. 
     (5) The regulating wall  60  has the main-body-side regulating wall  61  that protrudes from the inner surface of the second main body portion  52 , and the lid-side regulating wall  62  that protrudes from the inner surface of the lid portion  56 . According to this configuration, if the first route-regulating member  40  is first inserted into the second main body portion  52 , the end surface  47 A in the lengthwise direction of the first route-regulating member  40  can be engaged with the main-body-side regulating wall  61 . Also, if the first route-regulating member  40  is first inserted into the lid portion  56 , the end surface  47 A in the lengthwise direction of the first route-regulating member  40  can be engaged with the lid-side regulating wall  62 . As a result, regardless of whether the first route-regulating member  40  is first inserted into either the second main body portion  52  or the lid portion  56 , the first route-regulating member  40  can be easily positioned with respect to the second route-regulating member  50 . 
     (6) The opening width of the second accommodation port  63  provided in the main-body-side regulating wall  61  is smaller than the outer diameter of the first route-regulating member  40 . Thus, if the first route-regulating member  40  is inserted into the covering portion  51 , the end surface  47 A in the lengthwise direction of the first route-regulating member  40  can be suitably engaged with the main-body-side regulating wall  61 . As a result, the first route-regulating member  40  can be suitably positioned with respect to the second route-regulating member  50 . 
     (7) The covering portion  51  has the projecting portion  65  that can come into contact with at least one of the first end portion  43  and the second end portion  44  that form the insertion port  42  in the circumferential direction of the first route-regulating member  40 . For this reason, the projecting portion  65  and the first end portion  43  or the second end portion  44  are engaged with each other in the circumferential direction of the first route-regulating member  40 . Due to the engagement between these portions, relative movement of the first route-regulating member  40  with respect to the covering portion  51  is suppressed in the circumferential direction of the first route-regulating member  40 . That is, due to the projecting portion  65  and the first end portion  43  or the second end portion  44  being engaged with each other, it is possible to suppress rotation of the first route-regulating member  40  in the circumferential direction with respect to the covering portion  51 . For this reason, it is possible to suppress positional misalignment of the first route-regulating member  40  with respect to the covering portion  51  in the circumferential direction of the first route-regulating member  40 , and the positional accuracy of the first route-regulating member  40  with respect to the covering portion  51  can be improved. 
     (8) Since the projecting portion  65  has protrusions  66  that enter the ring-shaped recesses  32  of the outer cover member  30 , it is possible to suppress movement of the outer cover member  30  with respect to the second route-regulating member  50  in the lengthwise direction of the outer cover member  30 . 
     (9) The regulating wall  60  is provided at the end portion that is connected to the route-regulating portion  70 , out of the two end portions in the lengthwise direction of the covering portion  51 . This regulating wall  60  regulates the amount by which the first route-regulating member  40  is inserted into the second route-regulating member  50  in the lengthwise direction of the wire harness main body  11 . Thus, it is possible to inhibit the first route-regulating member  40  from being inserted to the route-regulating portion  70  of the second route-regulating member  50  in the lengthwise direction of the wire harness main body  11 . That is, it is possible to inhibit the first route-regulating member  40  from being excessively inserted into the second route-regulating member  50  in the lengthwise direction of the wire harness main body  11 . 
     (10) The route of the straight section  11 A is regulated by the first route-regulating member  40 , and the route of the bent section  11 B is regulated by the second route-regulating member  50 . As a result, it is possible to prevent the route of the straight section  11 A and the route of the bent section  11 B from deviating from the desired routes. 
     (11) The first route-regulating member  40  has the protruding portion  45  that protrudes from the inner surface of at least one of the first end portion  43  and the second end portion  44  and can come into contact with the outer surface of the outer cover member  30 . With this protruding portion  45 , for example, the outer cover member  30  can be pressed from the outer side of the outer cover member  30 . For this reason, detachment of the first route-regulating member  40  from the outer cover member  30  through the insertion port  42  can be suitably suppressed. 
     Other Embodiments 
     The above embodiment can be modified and implemented as follows. The above embodiment and the following modifications can be implemented in combination with each other as long as no contradiction arises. 
     Although a gap is formed between the inner surface of the lid portion  56  and the outer surface of the first route-regulating member  40  in the above embodiment, the present disclosure is not limited to this. 
     As shown in  FIG.  7   , for example, the inner surface of the lid portion  56  may be in intimate contact with the outer surface of the first route-regulating member  40 . The inner surface of the lid portion  56  may be formed so as to press the outer surface of the first route-regulating member  40  inward in the radial direction of the covering portion  51 , for example. 
     As shown in  FIG.  8   , for example, a fastening allowance may be provided between the outer circumference of the first route-regulating member  40  and the inner circumference of the covering portion  51 . The smallest inner diameter d 2  of the covering portion  51  may be formed smaller than the largest outer diameter d 1  of the route-regulating member  40  before being inserted into the covering portion  51  in a state of being attached to the outer circumference of the outer cover member  30 , for example. Here, the first route-regulating member  40  in this modified example is configured such that, in a state in which the outer cover member  30  is inserted therein, the opening width of the insertion port  42  is slightly larger than its original width, that is, the width thereof when the outer cover member  30  is not inserted. In a state in which the outer cover member  30  is inserted into the first route-regulating member  40 , the outer diameter of the first route-regulating member  40  in this modified example is larger than the outer diameter thereof when the outer cover member  30  is not inserted by a protrusion amount of the protruding portion  45 , for example. Thus, the largest outer diameter d 1  in this modified example is the outer diameter of a portion of the first route-regulating member  40  that passes the protruding portion  45  before being inserted into the covering portion  51  in a state of being attached to the outer circumference of the outer cover member  30 . Also, the smallest inner diameter d 2  of this modified example is the inner diameter of the covering portion  51  at a position corresponding to the largest outer diameter d 1 . The smallest inner diameter d 2  is set smaller than the largest outer diameter d 1  by a protrusion amount of the protruding portion  45 , for example. 
     Because the largest outer diameter d 1  and the smallest inner diameter d 2  are set in this manner, the first route-regulating member  40  attached to the outer circumference of the outer cover member  30  is fitted to the inner circumference of the covering portion  51  with the fastening allowance interposed therebetween. As shown in  FIG.  7   , when the lid portion  56  is held at the closed position in a state in which the outer cover member  30  and the first route-regulating member  40  are accommodated in the covering portion  51 , the first route-regulating member  40  is fitted and fixed to the inner circumference of the covering portion  51  with the fastening allowance interposed therebetween, for example. As a result, the inner circumferential surface of the covering portion  51  and the outer circumferential surface of the first route-regulating member  40  are in contact with each other in a state in which the fastening allowance is present therebetween. In this modified example, the inner circumferential surface of the covering portion  51  and the outer circumferential surface of the first route-regulating member  40  are in contact with each other in a state in which the fastening allowance is present therebetween only at a plurality of positions spaced apart from each other in the circumferential direction of the covering portion  51 . As a result, the first route-regulating member  40  fitted into the covering portion  51  is held in a state of being constantly pressed inward in the radial direction of the covering portion  51  by the inner surface of the covering portion  51 . Therefore, rattling of the first route-regulating member  40  in the covering portion  51  can be suppressed. Also, relative movement of the first route-regulating member  40  with respect to the covering portion  51  is favorably suppressed in the lengthwise direction of the wire harness main body  11 . For this reason, it is possible to suitably suppress positional misalignment of the first route-regulating member  40  with respect to the covering portion  51  in the lengthwise direction of the wire harness main body  11 , and to suitably suppress detachment of the first route-regulating member  40  from the covering portion  51 . Further, relative movement of the first route-regulating member  40  with respect to the covering portion  51  is also suitably suppressed in the circumferential direction of the wire harness main body  11 . 
     Note that the electric wire member  20  is not shown in  FIGS.  7  and  8   .
         The structure of the second route-regulating member  50  of the above-described embodiment can be changed as appropriate. For example, as long as the second route-regulating member  50  has a structure that covers the connecting portion  47  and has the covering portion  51  provided with the regulating wall  60 , there is no particular limitation on the other structures.   Although the projecting portion  65  is provided on the inner surface of the lid portion  56  in the above embodiment, the present disclosure is not limited to this, and the projecting portion  65  may be provided on the inner surface of the second main body portion  52 . In this case, when the projecting portion  65  provided on the inner surface of the second main body portion  52  is inserted into the insertion port  42  of the first route-regulating member  40 , the projecting portion  65  is positioned so as to face the second main body portion  52  side of the covering portion  51  at a position in the circumferential direction of the insertion port  42  of the first route-regulating member  40 , for example.   The protrusions  66  of the lid portion  56  may also be omitted.   The projecting portion  65  of the lid portion  56  may also be omitted.   Either the main-body-side regulating wall  61  or the lid-side regulating wall  62  may also be omitted.   In the covering portion  51  of the above-described embodiment, the second main body portion  52  and the lid portion  56  are formed in one piece with each other, but there is no limitation to this, and the second main body portion  52  and the lid portion  56  may also be separate from each other. That is, the second main body portion  52  and the lid portion  56  may be separate components.   The lid portion  56  of the covering portion  51  may also be omitted.   The bent shape of the route-regulating portion  70  can be changed as appropriate.   The transverse cross-sectional shape of the inner surface of the second main body portion  52  and the third main body portion  71  is not limited to a U shape, and can be changed to, for example, an arc shape, an elliptical arc shape, or the like.   A lid portion to be coupled to the third main body portion  71  may be provided.   The second route-regulating member  50  of the above-described embodiment was formed so as to regulate the route of the bent section  11 B of the wire harness main body  11 , but there is no limitation to this. For example, the second route-regulating member  50  may be changed to a shape that regulates the route of the straight section  11 A of the wire harness main body  11 . The second route-regulating member  50  in this case is changed to, for example, a shape in which the bent shape of the route-regulating portion  70  extends linearly.   In the above-described embodiment, the second route-regulating member  50  is embodied as an attachment member (attachment) having a covering portion  51 , but there is no limitation to this. For example, the attachment member may be embodied in a structure having only the covering portion  51 .   The structure of the first route-regulating member  40  of the above-described embodiment can be changed as appropriate. For example, as long as the first route-regulating member  40  has the insertion port  42  and has a structure with which the first route-regulating member  40  can be attached to the outer circumference of the outer cover member  30 , there is no particular limitation to the other structures.   Each protruding portion  45  of the above-described embodiment may be provided at a position farther from the insertion port  42  than the leading ends  43 A and  44 A in the circumferential direction of the first route-regulating member  40 .   Each protruding portion  45  may be partially provided in the lengthwise direction of the first route-regulating member  40 .   At least one of the two protruding portions  45  may be omitted.   The first route-regulating member  40  may be provided with a second protruding portion that protrudes from the inner surface of the intermediate portion in the circumferential direction of the first main body portion  41  and can come into contact with the outer surface of the outer cover member  30 . According to this configuration, the protruding portion  45  and the second protruding portion can be brought into contact with the outer surface of the outer cover member  30  together. Therefore, rattling of the first route-regulating member  40  can be suppressed.   In the first route-regulating member  40 , a groove extending along the lengthwise direction may be provided on the outer surface of the first main body portion  41 . According to this configuration, the first main body portion  41  is easily deformed to the outer peripheral side using the groove as a starting point, whereby the insertion opening  42  can be more easily expanded. As a result, it is possible to contribute to making the first route-regulating member  40  easier to attach.   The thickness in the radial direction of the first main body portion  41  may be changed in the circumferential direction.   The transverse cross-sectional shape of the first main body portion  41  is not limited to an arc shape, but can be changed to, for example, an elliptical arc shape, a U shape, or the like.   In the above-described embodiment, the first route-regulating member  40  and the second route-regulating member  50  are more rigid than the outer cover member  30 , but there is no limitation to this, and the hardness may be less than or equal to that of the outer cover member  30 . That is, if the first route-regulating member  40  and the second route-regulating member  50  act so that the wire harness main body  11  is less likely to bend than the wire harness main body  11  in the state where the first route-regulating member  40  and the second route-regulating member  50  are not attached, the first route-regulating member  40  and the second route-regulating member  50  need not be more rigid than the outer cover member  30 .   The second route-regulating members  50  may also be provided on two sides in the lengthwise direction of the first route-regulating member  40  in the above embodiment.   At least one of the fixing members  81  and  82  in the above-described embodiment may be omitted.   For example, the outer cover member  30  in the above-described embodiment may be a resin corrugated tube with a metal layer that contains a metal material, formed on the outer surface thereof.   The outer cover member  30  in the above-described embodiment is not limited to being a corrugated tube, and may be an outer cover member that is not provided with an annular protrusion  31  or an annular recess  32 , for example.   The outer cover member  30  in the above-described embodiment may have a slit that extends in the lengthwise direction of the outer cover member  30 .   Although the electric wires  21  in the above-described embodiment are high-voltage electric wires, the present disclosure is not limited to such a configuration. For example, the electric wires  21  may be low-voltage electric wires.   In the electric wire member  20  in the above-described embodiment, an electromagnetic shield member is embodied as the braided member  25 . However, the present disclosure is not limited to such a configuration. For example, the electromagnetic shield member in the electric wire member  20  may be embodied as a metal foil.   The braided member  25  of the electric wire member  20  in the above-described embodiment may be omitted.   In the above-described embodiment, the number of electric wires  21  included in the electric wire member  20  is two. However, the present disclosure is not limited to such a configuration. The number of electric wires  21  may be one or three or more.   The positional relationship between the inverter M 1  and the high-voltage battery M 2  in the vehicle V is not limited to that in the above-described embodiment, and may be changed as appropriate depending on the vehicle configuration.   In the above-described embodiment, a plurality of on-board devices to which the wire harness  10  is to be electrically connected are embodied as the inverter M 1  and the high-voltage battery M 2 . However, the present disclosure is not limited to such a configuration. The plurality of on-board devices to which the wire harness  10  is to be electrically connected are not particularly limited as long as they are electric devices to be mounted in the vehicle V.   The embodiments disclosed herein are illustrative in all aspects and should not be considered restrictive. The scope of the present disclosure is indicated by the scope of claims, not the above-mentioned meaning, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
