[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. [1] A wire harness according to the present disclosure includes a wire harness main body having an electric wire member and an exterior member surrounding an outer periphery of the electric wire member, a first path regulating member attached to the outer periphery of the exterior member and regulating a path of the wire harness main body, and a second path regulating member attached to the outer periphery of the first path regulating member and regulating a path of the wire harness main body, wherein the second path regulating member covers a part of an outer periphery of the first path regulating member in a longitudinal direction of the wire harness main body, and is provided at a position offset from the first path regulating member in the longitudinal direction of the wire harness main body to cover an outer periphery of the exterior member exposed from the first path regulating member. The first path regulating member has a first main body portion covering a part of the outer periphery of the exterior member, and a first insertion opening that opens in a direction perpendicular to the longitudinal direction of the first main body portion and extends over the entire length of the first main body portion in the longitudinal direction, and the second path regulating member has a second main body portion covering the first path regulating member and a part of the outer periphery of the exterior member, and a second insertion opening that opens in a direction perpendicular to the longitudinal direction of the second main body portion and extends over the entire length of the second main body portion in the longitudinal direction, and the second path regulating member is slidable on the outer periphery of the first path regulating member in the longitudinal direction of the wire harness main body.

[0010] According to this configuration, a part of the first path regulating member in the length direction of the wire harness main body overlaps a part of the second path regulating member in the length direction. The second path regulating member covers a part of the outer periphery of the first path regulating member in the length direction of the wire harness main body, and covers an outer periphery of an exterior member provided at a position shifted from the first path regulating member in the length direction of the wire harness main body. The second path regulating member is slidable on the outer periphery of the first path regulating member relative to the first path regulating member in the length direction of the wire harness main body. As a result, the overlapping width between the first path regulating member and the second path regulating member can be easily adjusted by sliding the second path regulating member relative to the first path regulating member in the length direction of the wire harness main body. By adjusting this overlapping width, the entire length of the first path regulating member and the second path regulating member in the length direction of the wire harness main body can be easily adjusted. That is, by adjusting the overlapping width between the first path regulating member and the second path regulating member, the length of the section in which the path is regulated by the first path regulating member and the second path regulating member can be easily adjusted. Therefore, even if the length of the path regulating section is changed due to a change in specifications, such as the wiring path of the wire harness main body, the specification change can be easily accommodated by adjusting the overlapping width between the first path regulating member and the second path regulating member.

[0011] [2] The wire harness main body further includes an attachment member that is provided apart from the first path regulating member in the longitudinal direction and that is attached to the outer periphery of the exterior member, and the second path regulating member is attached from one end of the first path regulating member in the longitudinal direction to the attachment member, and the second path regulating member preferably has a first covering portion that covers the outer periphery of the first path regulating member and a second covering portion that covers the outer periphery of the attachment member. According to this configuration, the first path regulating member is interposed between the first covering portion of the second path regulating member and the outer surface of the exterior member, and the attachment member is interposed between the second covering portion of the second path regulating member and the outer surface of the exterior member. As a result, the gap between the inner surface of the first covering portion and the outer surface of the exterior member is filled with the first path regulating member, and the gap between the inner surface of the second covering portion and the outer surface of the exterior member is filled with the attachment member. As a result, the second path regulating member can be stably attached to the outer periphery of the exterior member via the first path regulating member and the attachment member.

[0012] [3] The mounting member is preferably a third path regulating member having the same cross-sectional shape as the first path regulating member. According to this configuration, the first path regulating member is interposed between the inner surface of the first covering portion and the outer surface of the exterior member, and the third path regulating member having the same cross-sectional shape as the first path regulating member is interposed between the inner surface of the second covering portion and the outer surface of the exterior member. This allows members of the same structure to be interposed between the first covering portion, the second covering portion, and the exterior member. Therefore, the second path regulating member can be more stably attached to the outer periphery of the exterior member via the first path regulating member and the third path regulating member.

[0013] [4] The mounting member is preferably shorter than the first path restricting member in the length direction of the wire harness main body. According to this configuration, the mounting member filling the gap between the inner surface of the second covering portion and the outer surface of the exterior member is formed shorter than the first path restricting member. Therefore, the mounting member is prevented from being unnecessarily long, and the material cost of the mounting member is prevented from increasing. This prevents the manufacturing cost of the wire harness from increasing.

[0014] [5] It is preferable that the second path regulating member further includes a first fixing member that fixes the first covering portion of the second path regulating member to an outer periphery of the first path regulating member. According to this configuration, for example, after adjusting the overlapping width between the first path regulating member and the second path regulating member, the first covering portion can be fixed to the first path regulating member by the first fixing member. This makes it possible to suitably prevent the overall length of the first path regulating member and the second path regulating member from being changed after adjusting the overlapping width between the first path regulating member and the second path regulating member.

[0015] [6] It is preferable that the wire harness further includes a second fixing member that fixes an end portion of the first path regulating member that is exposed from the second path regulating member in the length direction to an outer periphery of the exterior member, and a third fixing member that fixes the second covering portion of the second path regulating member to the outer periphery of the exterior member. According to this configuration, movement of the first path regulating member and the second path regulating member relative to the exterior member in the length direction of the wire harness main body is suppressed. Therefore, it is possible to suppress positional deviation of the first path regulating member and the second path regulating member relative to the exterior member in the length direction of the wire harness main body, and it is possible to improve the positional accuracy of the first path regulating member and the second path regulating member relative to the exterior member.

[0016] [7] The first path regulating member preferably has a first end and a second end which are both ends of the first main body in the circumferential direction and form the first insertion opening, and a first protrusion which protrudes from the inner surface of at least one of the first end and the second end and can contact the outer surface of the exterior member, and the second path regulating member preferably has a third end and a fourth end which are both ends of the second main body in the circumferential direction and form the second insertion opening, and a second protrusion which protrudes from the inner surface of at least one of the third end and the fourth end and can contact the outer surface of the first path regulating member. According to this configuration, the first path regulating member has a first protrusion which protrudes from the inner surface of at least one of the first end and the second end and can contact the outer surface of the exterior member. The first protrusion can hold the exterior member from the outside of the exterior member, for example. Therefore, it is possible to suitably suppress detachment of the first path regulating member from the exterior member through the first insertion opening. In addition, the second path regulating member has a second protrusion which protrudes from the inner surface of at least one of the third end and the fourth end and can contact the outer surface of the first path regulating member. The second protruding portion can hold the first path regulating member from, for example, the outside of the first path regulating member, which can suitably prevent the second path regulating member from coming off the first path regulating member through the second insertion opening.

[0017] [8] The second path regulating member is attached to the outer periphery of the first path regulating member such that the orientation of the second insertion opening is different from the orientation of the first insertion opening, and the first path regulating member has a recess recessed from the outer surface of the first main body portion, and the second protrusion is preferably capable of being fitted into the recess and engaging with the recess in the circumferential direction of the wire harness main body. According to this configuration, the recess provided on the outer surface of the first main body portion and the second protrusion provided on the inner surface of the second main body portion are fitted into each other in the circumferential direction of the wire harness main body, so that the recess and the second protrusion are engaged with each other in the circumferential direction of the wire harness main body. This makes it possible to suppress the relative movement of the second path regulating member with respect to the first path regulating member in the circumferential direction of the wire harness main body. In other words, it is possible to suppress the second path regulating member from rotating in the circumferential direction with respect to the first path regulating member.

[0018] [9] The second path regulating member is preferably attached to the outer periphery of the first path regulating member so that the orientation of the second insertion opening coincides with the orientation of the first insertion opening, and the second protrusion is preferably provided inside the first insertion opening and can contact at least one of the first end and the second end in the circumferential direction of the wire harness main body. According to this configuration, the second protrusion of the second path regulating member is provided inside the first insertion opening and can contact at least one of the first end and the second end forming the first insertion opening in the circumferential direction of the wire harness main body. Therefore, the second protrusion is engaged with the first end or the second end in the circumferential direction of the wire harness main body. This can suitably suppress the second path regulating member from rotating in the circumferential direction relative to the first path regulating member.

[0019] [Details of the embodiment of the present disclosure] Specific examples of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, some of the configurations may be exaggerated or simplified. In addition, the dimensional ratio of each part may differ in each drawing. In this specification, "orthogonal," "parallel," and "total length" do not only mean strictly orthogonal, parallel, or total length, but also include roughly orthogonal, parallel, or total length within the range of the action and effect of this embodiment. In this specification, "same" includes not only exactly the same, but also a case where there is some difference between the compared objects due to the influence of dimensional tolerances, etc. In addition, "cylindrical" as used in the description of this specification includes not only those in which a peripheral wall is formed continuously around the entire circumference, but also those in which a plurality of parts are combined to form a cylindrical shape, and those having a notch in a part of the circumference such as a C-shape. In addition, the shape of "cylindrical" includes, but is not limited to, a circle, an ellipse, and a polygon with sharp or rounded corners. In addition, the term "annular" as used in the present description may refer to any structure that forms a loop, or a continuous shape with no ends, as well as a generally loop-shaped structure with gaps, such as a C-shape. Note that "annular" shapes include, but are not limited to, circles, ellipses, and polygons with sharp or rounded corners. Note that the present invention is not limited to these examples, and is intended to include all modifications within the meaning and scope of the claims, as defined by the claims.

[0020] (Overall configuration of the wire harness 10) A wire harness 10 shown in FIG. 1 is mounted on a vehicle V such as a hybrid vehicle or an electric vehicle. The wire harness 10 electrically connects two or more in-vehicle devices to each other. The in-vehicle devices are electrical devices mounted on the vehicle V. The wire harness 10 electrically connects, for example, an inverter M1 installed at the front of the vehicle V and a high-voltage battery M2 installed behind the inverter M1 on the vehicle V. The wire harness 10 is formed in an elongated shape so as to extend, for example, in the front-rear direction of the vehicle V. The wire harness 10 is routed in the vehicle V so that, for example, a middle portion of the length of the wire harness 10 passes outside the passenger compartment, such as under the floor of the vehicle V.

[0021] The inverter M1 is connected to, for example, a wheel drive motor (not shown) that serves as a power source for driving the vehicle. The inverter M1 generates AC power from DC power of a high-voltage battery M2 and supplies the AC power to the motor. The high-voltage battery M2 is, for example, a battery capable of supplying a voltage of several hundred volts.

[0022] The wire harness 10 has a wire harness main body 11. The wire harness main body 11 has an electric wire member 20 and a cylindrical exterior member 30 that surrounds the outer periphery of the electric wire member 20. The wire harness 10 has connectors C1, C2 attached to both ends of the electric wire member 20. One end in the length direction of the electric wire member 20 is connected to the inverter M1 via the connector C1, and the other end in the length direction of the electric wire member 20 is connected to the high-voltage battery M2 via the connector C2.

[0023] 2, the wire harness 10 has a first path regulating member 40 attached to the outer periphery of the exterior member 30, a second path regulating member 50 attached to the outer periphery of the first path regulating member 40, and a third path regulating member 60 attached to the outer periphery of the exterior member 30. The first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 regulate the route along which the wire harness main body 11 is routed. Note that the first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 are not shown in FIG.

[0024] (Configuration of the electric wire member 20) As shown in Figs. 3 to 5, the electric wire member 20 has, for example, one or more electric wires 21 (two in this embodiment) and a braided member 25 that collectively surrounds the outer periphery of the multiple electric wires 21.

[0025] Each electric wire 21 is a covered electric wire having a conductive core wire 22 and an insulating covering 23 that surrounds the outer periphery of the core wire 22 and has insulating properties. Each electric wire 21 is, for example, a high-tension electric wire that can handle high voltage and large current. Each electric wire 21 may be, for example, a non-shielded electric wire that does not have an electromagnetic shield structure itself, or a shielded electric wire that has an electromagnetic shield structure itself. Each electric wire 21 in this embodiment is a non-shielded electric wire.

[0026] The core wire 22 may be, for example, a stranded wire made of a plurality of metal wires stranded together, or a single core wire made of a single conductor. The single core wire may be, for example, a columnar conductor made of a single metal rod having a solid interior structure, or a tubular conductor having a hollow interior structure. The core wire 22 may be a combination of a stranded wire, a columnar conductor, and a tubular conductor. The material of the core wire 22 may be, for example, a copper-based or aluminum-based metal material.

[0027] The insulating coating 23, for example, covers the entire outer circumferential surface of the core wire 22. The insulating coating 23 is made of, for example, a resin material having insulating properties. The cross-sectional shape of each electric wire 21 cut by a plane perpendicular to the length direction of each electric wire 21, that is, the transverse cross-sectional shape of each electric wire 21, can be formed into any shape. The transverse cross-sectional shape of each electric wire 21 is formed into, for example, a circular shape, a semicircular shape, a polygonal shape, a square shape, a flat shape, or the like. The transverse cross-sectional shape of each electric wire 21 in this embodiment is formed into a circular shape.

[0028] The braided member 25 has, for example, a cylindrical shape that collectively surrounds the outer circumference of the plurality of electric wires 21. As the braided member 25, for example, a braided wire in which a plurality of metal wires are woven, or a braided wire in which metal wires and resin wires are combined and woven, can be used. As the material of the metal wires, for example, a copper-based or aluminum-based metal material can be used. Although not shown in the drawings, both ends of the braided member 25 in the length direction are earthed, for example, by connectors C1 and C2 (see FIG. 1).

[0029] (Configuration of exterior member 30) As shown in Fig. 5, the exterior member 30 has a tubular shape surrounding the outer periphery of the electric wire member 20 over the entire circumferential direction. The exterior member 30 of this embodiment is formed in a cylindrical shape. For example, the exterior member 30 is sealed over the entire circumferential direction of the exterior member 30. The exterior member 30 has a function of protecting the electric wire member 20 from, for example, flying objects and water droplets.

[0030] The exterior member 30 is, for example, flexible and easily bendable. Examples of the flexible exterior member 30 include a resin corrugated tube and a rubber waterproof cover. The exterior member 30 of this embodiment is a resin corrugated tube having a bellows structure in which annular convex portions 31 and annular concave portions 32 are alternately arranged along the length direction of the exterior member 30. Each of the annular convex portions 31 and the annular concave portions 32 forms, for example, a ring that goes around once along the circumferential direction of the exterior member 30. As the material of the exterior member 30, for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin can be used.

[0031] (Configuration of the first path regulating member 40, the second path regulating member 50, and the third path regulating member 60) As shown in FIG. 2, each of the first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 is partially provided in the length direction of the wire harness main body 11. For example, the first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 regulate the path of the wire harness main body 11 at a straight portion 11A that is a straight portion of the path of the wire harness main body 11. Here, the straight portion 11A is a portion where the path of the wire harness main body 11 extends straight in one direction. The first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 hold the exterior member 30 at the straight portion 11A. Each of the first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 is, for example, harder than the exterior member 30. Each of the first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 has a hardness that makes it difficult to bend in a direction perpendicular to the length direction of the wire harness main body 11, compared to the exterior member 30. For example, the first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 assist the exterior member 30 so that the wire harness main body 11 does not bend due to its own weight or the like and deviate from a desired path. The exterior member 30 is difficult to bend, for example, compared to a state in which the first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 are not attached.

[0032] The first path regulating member 40 and the third path regulating member 60 are provided apart from each other in the length direction of the wire harness main body 11. In other words, between the first path regulating member 40 and the third path regulating member 60 in the length direction of the wire harness main body 11, the outer surface of the exterior member 30 is exposed from the first path regulating member 40 and the third path regulating member 60. The second path regulating member 50 covers a part of the outer periphery in the length direction of the first path regulating member 40, and covers the outer periphery of the exterior member 30 provided at a position shifted from the first path regulating member 40 in the length direction of the wire harness main body 11 and exposed from the first path regulating member 40. The second path regulating member 50 is slidable on the outer periphery of the first path regulating member 40 in the length direction of the wire harness main body 11. That is, the second path regulating member 50 is slidable relative to the first path regulating member 40 in the length direction of the wire harness main body 11.

[0033] The second path regulating member 50 of the present embodiment is provided in the length direction of the wire harness main body 11 from one end of the first path regulating member 40 in the length direction to the third path regulating member 60. Here, the second path regulating member 50 has a first covering portion 51 covering the outer periphery of the first path regulating member 40 and a second covering portion 52 covering the outer periphery of the third path regulating member 60. The first covering portion 51 is provided, for example, at one end of the second path regulating member 50 in the length direction. The first covering portion 51 is provided so as to overlap one end of the first path regulating member 40 in the length direction of the wire harness main body 11. The second covering portion 52 is provided, for example, at an end of the second path regulating member 50 on the opposite side to the first covering portion 51 in the length direction. The second covering portion 52 is provided so as to overlap one end of the third path regulating member 60 in the length direction of the wire harness main body 11. The second path regulating member 50 of the present embodiment covers the outer periphery of the exterior member 30 provided between the first path regulating member 40 and the third path regulating member 60 in the length direction of the wire harness main body 11. That is, a portion between the first covering portion 51 and the second covering portion 52 in the length direction of the second path regulating member 50 covers the outer periphery of the exterior member 30 provided between the first path regulating member 40 and the third path regulating member 60 in the length direction of the wire harness main body 11. Note that the first path regulating member 40 is exposed from the second path regulating member 50 at a portion other than one end portion in the length direction of the first path regulating member 40. The third path regulating member 60 is exposed from the second path regulating member 50 at a portion other than one end portion in the length direction of the third path regulating member 60, for example.

[0034] (Configuration of the first path regulating member 40) As shown in FIG. 3, the first path regulating member 40 covers a part of the outer periphery of the exterior member 30 in the circumferential direction of the exterior member 30. The first path regulating member 40 is tubular and covers the outer periphery of the exterior member 30 in a part of the circumferential direction of the exterior member 30. The first path regulating member 40 covers, for example, an area larger than half of the outer periphery of the exterior member 30. The cross-sectional shape of the first path regulating member 40 is generally C-shaped. The cross-sectional shape of the first path regulating member 40 is uniform over the entire length of the first path regulating member 40 in the longitudinal direction, for example. As shown in FIG. 2, the first path regulating member 40 extends, for example, along the path of the straight portion 11A, and is formed in a shape that extends linearly in one direction.

[0035] The first path regulating member 40 is made of, for example, metal or resin. In the present embodiment, the first path regulating member 40 is made of resin. As the material of the first path regulating member 40, for example, synthetic resin such as polypropylene, polyamide, polyacetal, etc. can be used. The first path regulating member 40 can be manufactured by, for example, extrusion molding, injection molding, etc.

[0036] 3, the first path regulating member 40 has a first main body portion 41 that covers a part of the outer periphery of the exterior member 30, and a first insertion opening 42 that opens in a direction perpendicular to the longitudinal direction of the first main body portion 41. The first path regulating member 40 has a first end portion 43 and a second end portion 44 that are both circumferential ends of the first main body portion 41 and form the first insertion opening 42.

[0037] The first main body portion 41 constitutes a main portion of the first path regulating member 40. The radial thickness of the first main body portion 41 is, for example, uniform in the circumferential direction of the first path regulating member 40. The cross-sectional shape of the first main body portion 41 is, for example, formed into a shape that follows the outer surface of the exterior member 30. The cross-sectional shape of the first main body portion 41 is, for example, formed into an arc shape.

[0038] The first end 43 and the second end 44 are provided on opposite sides of each other in the circumferential direction of the first main body portion 41. The first end 43 and the second end 44 are provided apart from each other in the circumferential direction of the first main body portion 41 with the first insertion opening 42 therebetween. In other words, a gap between the first end 43 and the second end 44 in the circumferential direction of the first path regulating member 40 is configured as the first insertion opening 42. In this manner, the first path regulating member 40 is formed in a C-shape having the first insertion opening 42 at a part of the circumferential direction of the first main body portion 41.

[0039] The opening width of the first insertion opening 42, i.e., the shortest distance between the first end 43 and the second end 44, is smaller than, for example, the outer diameter of the exterior member 30. As shown in Fig. 5, the first insertion opening 42 extends along the length of the first main body portion 41 over the entire length of the first main body portion 41. That is, the first insertion opening 42 is formed so as to open in a direction perpendicular to the length of the first main body portion 41 and to open at both ends of the first main body portion 41 in the length direction.

[0040] By inserting the exterior member 30 into the first insertion opening 42 from a direction perpendicular to the length direction of the first path regulating member 40, the first path regulating member 40 elastically deforms and the opening width of the first insertion opening 42 increases. When the exterior member 30 is inserted inside the first path regulating member 40, the first path regulating member 40 elastically returns to its original shape. As a result, the opening width of the first insertion opening 42 becomes smaller than the outer diameter of the exterior member 30, and the first path regulating member 40 is attached to the outer periphery of the exterior member 30.

[0041] As shown in Fig. 3, the first end 43 has a tip 43A. The second end 44 has a tip 44A. The tips 43A, 44A form the first insertion opening 42. The tips 43A, 44A are formed in a curved shape when viewed in the longitudinal direction of the first path regulating member 40. That is, the cross-sectional shape of the tips 43A, 44A is formed in a curved shape. In this embodiment, the cross-sectional shape of the tips 43A, 44A is formed in a semicircular shape.

[0042] The first path regulating member 40 has, for example, a first protrusion 45 protruding from each of the inner surfaces of the first end 43 and the second end 44. Each of the first protrusions 45 protrudes toward the exterior member 30 inserted inside the first path regulating member 40 and can contact the outer surface of the exterior member 30. Each of the first protrusions 45 contacts, for example, the outer surface of the annular convex portion 31 of the exterior member 30. The two first protrusions 45 protrude, for example, from the inner surfaces of the tips 43A and 44A. The cross-sectional shape of each of the first protrusions 45 is formed, for example, in a curved shape. The cross-sectional shape of each of the first protrusions 45 in this embodiment is formed in a semicircular shape. Each of the first protrusions 45 extends along the length direction of the first path regulating member 40 over the entire length of the first path regulating member 40 in the length direction.

[0043] The first path regulating member 40 has, for example, one or more (two in this embodiment) holding protrusions 46 protruding from the inner surface of the first main body portion 41. Each holding protrusion 46 protrudes from the inner surface of the first main body portion 41 toward the exterior member 30 and can contact the outer surface of the exterior member 30. Each holding protrusion 46 is in contact with, for example, the outer surface of the annular convex portion 31 of the exterior member 30. The two holding protrusions 46 are provided at an interval from each other in the circumferential direction of the first path regulating member 40. The cross-sectional shape of each holding protrusion 46 is formed in a curved shape. The cross-sectional shape of each holding protrusion 46 in this embodiment is formed in, for example, a semicircular shape. Each holding protrusion 46 extends, for example, over the entire length of the first path regulating member 40 along the length direction of the first path regulating member 40.

[0044] The first protrusions 45 and the holding protrusions 46, for example, press the exterior member 30 from the outside of the exterior member 30. The exterior member 30 is, for example, elastically sandwiched between the first protrusions 45 and the holding protrusions 46. This strengthens the connection of the first path regulating member 40 to the exterior member 30. Therefore, the first path regulating member 40 attached to the outer periphery of the exterior member 30 is suppressed from moving in the length direction of the exterior member 30.

[0045] Since the first protrusions 45 and the holding protrusions 46 come into contact with the outer surface of the exterior member 30, a gap is generated between the inner surface of the first main body portion 41 and the outer surface of the exterior member 30. This gap is generated over the entire length of the first path regulating member 40 in the longitudinal direction.

[0046] The first path regulating member 40 has, for example, one or more (two in this embodiment) recesses recessed from the outer surface of the first main body portion 41. Each recess 47 is provided, for example, on the outer surface of the portion of the first main body portion 41 where each retaining protrusion 46 is provided. Each recess 47 is provided, for example, at a position overlapping with each retaining protrusion 46 in the radial direction of the first path regulating member 40. Each recess 47 is formed so as to recess from the outer surface of the first main body portion 41 toward the radial inside of the first path regulating member 40. Each recess 47 is a recess that does not penetrate the first main body portion 41 in the radial direction. The cross-sectional shape of each recess 47 is formed in a curved shape. The cross-sectional shape of each recess 47 in this embodiment is formed in a semicircular shape. As shown in FIG. 5, each recess 47 extends, for example, along the length direction of the wire harness main body 11. Each recess 47 extends, for example, along the length direction of the first main body portion 41 over the entire length of the first main body portion 41 in the length direction.

[0047] (Configuration of the third path regulating member 60) As shown in FIG. 4, the third path regulating member 60 covers a part of the outer periphery of the exterior member 30 in the circumferential direction of the exterior member 30. The third path regulating member 60 is tubular and covers the outer periphery of the exterior member 30 in a part of the circumferential direction of the exterior member 30. The third path regulating member 60 covers, for example, a range larger than half of the outer periphery of the exterior member 30. The cross-sectional shape of the third path regulating member 60 is generally C-shaped. The cross-sectional shape of the third path regulating member 60 is uniform, for example, over the entire length of the third path regulating member 60 in the longitudinal direction. The third path regulating member 60 of this embodiment has the same cross-sectional shape as the first path regulating member 40. Therefore, in the third path regulating member 60, the same components as those of the first path regulating member 40 are denoted by the same reference numerals, and the description thereof will be omitted. As shown in FIG. 2, the third path regulating member 60 extends, for example, along the path of the straight portion 11A, and is formed in a shape that extends linearly in one direction. In the length direction of the wire harness main body 11, the third path restricting member 60 is shorter than the first path restricting member 40.

[0048] The third path regulating member 60 is made of, for example, metal or resin. The third path regulating member 60 of the present embodiment is made of resin. As the material of the third path regulating member 60, for example, synthetic resin such as polypropylene, polyamide, polyacetal, etc. The third path regulating member 60 can be manufactured by, for example, extrusion molding, injection molding, etc.

[0049] (Configuration of the second path regulating member 50) 3 and 4, the second path regulating member 50 covers a part of the outer periphery of the exterior member 30 in the circumferential direction of the exterior member 30. The second path regulating member 50 has a cylindrical shape that covers the outer periphery of the exterior member 30 in a part of the circumferential direction of the exterior member 30. The second path regulating member 50 covers an area larger than half of the outer periphery of the exterior member 30, for example.

[0050] 3, the first covering portion 51 of the second path regulating member 50 covers a part of the outer periphery of the first path regulating member 40 in the circumferential direction of the first path regulating member 40. The first covering portion 51 covers, for example, an area larger than half of the outer periphery of the first path regulating member 40. As shown in FIG. 4, the second covering portion 52 of the second path regulating member 50 covers a part of the outer periphery of the third path regulating member 60 in the circumferential direction of the third path regulating member 60. The second covering portion 52 covers an area larger than half of the outer periphery of the third path regulating member 60.

[0051] The cross-sectional shape of the second path regulating member 50 is generally C-shaped. The cross-sectional shape of the second path regulating member 50 is uniform, for example, over the entire length of the second path regulating member 50 in the longitudinal direction. As shown in Fig. 2, the second path regulating member 50 extends, for example, along the path of the straight portion 11A, and is formed in a shape that extends linearly in one direction.

[0052] The second path regulating member 50 is made of, for example, metal or resin. In the present embodiment, the second path regulating member 50 is made of resin. As the material of the second path regulating member 50, for example, synthetic resin such as polypropylene, polyamide, polyacetal, etc. can be used. The second path regulating member 50 can be manufactured by, for example, extrusion molding, injection molding, etc.

[0053] 3, the second path regulating member 50 has a second main body portion 53 that covers a part of the outer periphery of the exterior member 30, and a second insertion opening 54 that opens in a direction perpendicular to the longitudinal direction of the second main body portion 53. The second path regulating member 50 has a third end portion 55 and a fourth end portion 56 that are both circumferential ends of the second main body portion 53 and form the second insertion opening 54.

[0054] The second main body portion 53 constitutes a main portion of the second path regulating member 50. The radial thickness of the second main body portion 53 is, for example, uniform in the circumferential direction of the second path regulating member 50. The cross-sectional shape of the second main body portion 53 is, for example, formed to a shape that follows the outer surface of the exterior member 30. The cross-sectional shape of the second main body portion 53 is, for example, formed to a shape that follows the outer surface of the first path regulating member 40. The cross-sectional shape of the second main body portion 53 is, for example, formed to be an arc shape.

[0055] The third end 55 and the fourth end 56 are provided on opposite sides of the second main body 53 in the circumferential direction. The third end 55 and the fourth end 56 are provided apart from each other in the circumferential direction of the second main body 53 with the second insertion opening 54 therebetween. In other words, a gap between the third end 55 and the fourth end 56 in the circumferential direction of the second path regulating member 50 is configured as the second insertion opening 54. In this manner, the second path regulating member 50 is formed in a C-shape having the second insertion opening 54 at a part of the circumferential direction of the second main body 53.

[0056] The opening width of the second insertion opening 54, i.e., the shortest distance between the third end 55 and the fourth end 56, is smaller than the maximum outer diameter of the first path regulating member 40, for example. The opening width of the second insertion opening 54 is smaller than the outer diameter of the exterior member 30, for example. As shown in FIG. 5, the second insertion opening 54 extends along the length of the second main body 53. The second insertion opening 54 extends over the entire length of the second main body 53 in the length direction. That is, the second insertion opening 54 is formed so as to open in a direction perpendicular to the length direction of the second main body 53 and to open at both ends of the second main body 53 in the length direction.

[0057] The second path regulating member 50 is attached to the outer periphery of the first path regulating member 40 and the third path regulating member 60 (see FIG. 4 ) so that the orientation of the second insertion opening 54 is different from the orientation of the first insertion opening 42. In this embodiment, the orientation of the second insertion opening 54 is set to be exactly opposite to the orientation of the first insertion opening 42. That is, as shown in FIG. 3 , the orientation of the first insertion opening 42 and the orientation of the second insertion opening 54 are set to be opposite to each other in the radial direction of the exterior member 30. In other words, the first insertion opening 42 and the second insertion opening 54 open in opposite directions to each other in the radial direction of the exterior member 30. In addition, the second main body portion 53 covers, for example, the first insertion opening 42. The second main body portion 53 covers, for example, the outer periphery of the exterior member 30 exposed from the first insertion opening 42.

[0058] By inserting the exterior member 30 and the first path regulating member 40 into the second insertion opening 54 from a direction perpendicular to the length direction of the second path regulating member 50, the second path regulating member 50 is elastically deformed, and the opening width of the second insertion opening 54 becomes larger. When the exterior member 30 and the first path regulating member 40 are inserted into the inside of the second path regulating member 50, the second path regulating member 50 elastically returns to its original shape. As a result, the opening width of the second insertion opening 54 becomes smaller than the outer diameter of the first path regulating member 40, and the second path regulating member 50 is attached to the outer periphery of the first path regulating member 40. The second path regulating member 50 is also attached to the outer periphery of the third path regulating member 60 (see FIG. 4) in a similar manner.

[0059] As shown in Fig. 3 and Fig. 4, the third end 55 has a tip 55A. The fourth end 56 has a tip 56A. The tips 55A, 56A form the second insertion opening 54. The cross-sectional shapes of the tips 55A, 56A are formed in a curved shape. In this embodiment, the cross-sectional shapes of the tips 55A, 56A are formed in a semicircular shape.

[0060] The second path regulating member 50 has, for example, second protrusions 57 protruding from the inner surfaces of the third end 55 and the fourth end 56. Each second protrusion 57 protrudes toward the first body 41 inserted into the second path regulating member 50. Each second protrusion 57 can contact the outer surface of the first body 41. Each second protrusion 57 can be fitted into each recess 47 provided in the first body 41. In other words, each recess 47 is provided at a position where it can be fitted into each second protrusion 57 when the second path regulating member 50 is attached so that the second insertion opening 54 and the first insertion opening 42 face in opposite directions. Here, when each second protrusion 57 is fitted into each recess 47, the side surface of each second protrusion 57 and the inner surface of each recess 47 are engaged with each other in the circumferential direction of the wire harness main body 11. As a result, the movement of the second path regulating member 50 relative to the first path regulating member 40 in the circumferential direction of the wire harness main body 11 is suppressed. Similarly, the movement of the second path regulating member 50 relative to the third path regulating member 60 in the circumferential direction of the wire harness main body 11 is suppressed. The cross-sectional shape of each second protrusion 57 is formed, for example, in a shape that follows the inner surface of each recess 47. The cross-sectional shape of each second protrusion 57 is formed, for example, in a curved shape. The cross-sectional shape of each second protrusion 57 in this embodiment is formed in a semicircular shape. For example, each second protrusion 57 extends along the length direction of the second path regulating member 50 over the entire length of the second path regulating member 50 in the length direction.

[0061] The inner diameter of the second main body 53 is formed to be larger than the outer diameter of the exterior member 30. For example, the inner diameter of the second main body 53 is formed to be larger than the outer diameter of the exterior member 30 to such an extent that when the exterior member 30 is inserted inside, only one of the inner surface of the second main body 53 and the second protrusion 57 contacts the outer surface of the exterior member 30, and the other cannot contact the outer surface of the exterior member 30. For this reason, for example, when the second covering part 52 is directly attached to the outer surface of the exterior member 30, the length direction of the second path regulating member 50 is inclined in a direction intersecting with the length direction of the exterior member 30. In contrast, in this embodiment, a third path regulating member 60 is interposed between the inner surface of the second covering part 52 and the outer surface of the exterior member 30. The third path regulating member 60 fills the gap between the inner surface of the second covering part 52 and the outer surface of the exterior member 30. For this reason, it is possible to suitably suppress the length direction of the second path regulating member 50 from being inclined obliquely with respect to the length direction of the exterior member 30. As a result, the second path regulating member 50 can be stably attached to the outer periphery side of the exterior member 30 via the first path regulating member 40 and the third path regulating member 60.

[0062] (Configuration of first fixing member 71, second fixing member 72, and third fixing member 73) As shown in FIG. 2, the wire harness 10 has, for example, a first fixing member 71 that fixes the first covering portion 51 of the second path regulating member 50 to the outer periphery of the first path regulating member 40. The wire harness 10 has, for example, a second fixing member 72 that fixes an end portion of the first path regulating member 40 in the length direction that is exposed from the second path regulating member 50 to the outer periphery of the exterior member 30. The wire harness 10 has, for example, a third fixing member 73 that fixes the second covering portion 52 of the second path regulating member 50 to the outer periphery of the exterior member 30. As the first fixing member 71, the second fixing member 72, and the third fixing member 73, for example, a resin or metal cable tie, a crimping ring, an adhesive tape, or the like can be used. The first fixing member 71, the second fixing member 72, and the third fixing member 73 of this embodiment are adhesive tapes.

[0063] The first fixing member 71 is wound from the first covering portion 51 to the first path regulating member 40. The first fixing member 71 is wound from the outer surface of the first covering portion 51 to the outer surface of the first path regulating member 40 exposed from the second path regulating member 50. The first fixing member 71 covers the outer periphery of the first covering portion 51 and the outer periphery of the first path regulating member 40 over the entire circumferential direction. This first fixing member 71 can suppress the second path regulating member 50 from moving relative to the first path regulating member 40 in the length direction and circumferential direction of the wire harness main body 11. The second fixing member 72 is wound from the outer surface of the end exposed from the second path regulating member 50 among both ends in the length direction of the first path regulating member 40 to the outer surface of the exterior member 30. The second fixing member 72 covers the outer periphery of the first path regulating member 40 and the outer periphery of the exterior member 30 over the entire circumferential direction. The second fixing member 72 can suppress the first path regulating member 40 from moving relative to the exterior member 30 in the length direction and circumferential direction of the wire harness main body 11. The third fixing member 73 is wrapped around the second covering portion 52 and the exterior member 30. The third fixing member 73 is wrapped around, for example, the outer surface of the second covering portion 52 through the outer surface of the third path regulating member 60 and the outer surface of the exterior member 30. The third fixing member 73 covers the outer periphery of the second path regulating member 50, the outer periphery of the third path regulating member 60, and the outer periphery of the exterior member 30 over the entire circumferential direction. The third fixing member 73 can suppress the second path regulating member 50 and the third path regulating member 60 from moving relative to the exterior member 30 in the length direction and circumferential direction of the wire harness main body 11.

[0064] 1 and 3 to 5, the first fixing member 71, the second fixing member 72, and the third fixing member 73 are omitted from the illustration. Next, the operation of this embodiment will be described.

[0065] In the length direction of the wire harness main body 11, a part of the first path regulating member 40 and a part of the second path regulating member 50 are provided so as to overlap with each other. The second path regulating member 50 covers the outer periphery of a part of the first path regulating member 40 in the length direction, and covers the outer periphery of the exterior member 30 provided at a position shifted from the first path regulating member 40 in the length direction of the wire harness main body 11. The second path regulating member 50 is slidable on the outer periphery of the first path regulating member 40 in the length direction of the wire harness main body 11. As a result, the overlapping width between the first path regulating member 40 and the second path regulating member 50 can be easily adjusted by sliding the second path regulating member 50 relative to the first path regulating member 40 in the length direction of the wire harness main body 11. By adjusting the overlapping width, the overall length of the first path regulating member 40 and the second path regulating member 50 in the length direction of the wire harness main body 11 can be easily adjusted. In other words, by adjusting the overlapping width between the first path regulating member 40 and the second path regulating member 50, the length of the section regulated by the first path regulating member 40 and the second path regulating member 50 can be easily adjusted.

[0066] As shown in FIG. 6, by sliding the second path regulating member 50 relative to the first path regulating member 40, for example, the second path regulating member 50 can be arranged so as to cover the outer periphery of the first path regulating member 40 over the entire length of the first path regulating member 40 in the length direction. That is, the first path regulating member 40 and the second path regulating member 50 can be arranged together in the length direction of the wire harness main body 11. By adopting this configuration, for example, the entire length of the first path regulating member 40 and the second path regulating member 50 can be shortened during transportation of the wire harness 10. As a result, the exterior member 30 located between the second path regulating member 50 and the third path regulating member 60 can be bent during transportation, so that the packaging size of the wire harness 10 during transportation can be reduced. As a result, an increase in the transportation cost of the wire harness 10 can be suitably suppressed. In the state shown in FIG. 6, the first fixing member 71 shown in FIG. 2 is not provided. Therefore, for example, after the transportation of the wire harness 10 is completed, the second path restricting member 50 can be slidably moved relative to the first path restricting member 40.

[0067] As shown in Fig. 7, by sliding the second path regulating member 50 toward the third path regulating member 60 from the state shown in Fig. 6, the overall length of the first path regulating member 40 and the second path regulating member 50 can be changed (see the arrow in the figure). At this time, by providing the third path regulating member 60 at a position corresponding to one end of the path regulating section, the second path regulating member 50 can be easily positioned in the length direction of the wire harness main body 11 when the second path regulating member 50 is slid. After the second path regulating member 50 is slid to the third path regulating member 60, for example, the first fixing member 71, the second fixing member 72, and the third fixing member 73 shown in Fig. 2 are provided.

[0068] Next, the effects of this embodiment will be described. (1) The second path regulating member 50 is configured to be slidable on the outer periphery of the first path regulating member 40 in the length direction of the wire harness main body 11. With this configuration, the overall length of the first path regulating member 40 and the second path regulating member 50 can be easily adjusted by adjusting the overlapping width between the first path regulating member 40 and the second path regulating member 50. Therefore, even if the length of the path regulating section is changed due to a change in the specifications of the wiring path of the wire harness main body 11, for example, the change in the specifications can be easily accommodated by adjusting the overlapping width between the first path regulating member 40 and the second path regulating member 50.

[0069] (2) The first insertion opening 42 of the first path regulating member 40 opens in a direction perpendicular to the longitudinal direction of the first main body 41 and extends over the entire longitudinal length of the first main body 41. This makes it possible to attach the first path regulating member 40 to the exterior member 30 through the first insertion opening 42 after performing terminal processing such as attaching the connectors C1, C2 to the longitudinal ends of the electric wire member 20. In this manner, since the first path regulating member 40 can be attached later, it is possible to improve the ease of assembly of the wire harness 10.

[0070] (3) The second insertion opening 54 of the second path regulating member 50 opens in a direction perpendicular to the longitudinal direction of the second main body portion 53 and extends over the entire longitudinal length of the second main body portion 53. This allows the second path regulating member 50 to be later attached to the outer periphery of the exterior member 30 and the outer periphery of the first path regulating member 40 through the second insertion opening 54. As a result, it is possible to improve the ease of assembly of the wire harness 10.

[0071] (4) In the portion where the first path regulating member 40 and the second path regulating member 50 are provided so as to overlap, the first path regulating member 40 and the second path regulating member 50 are attached in a double manner to the outer periphery of the exterior member 30. Therefore, in the portion where the first path regulating member 40 and the second path regulating member 50 are provided so as to overlap, the bending rigidity of the wire harness 10 can be increased.

[0072] (5) The first path regulating member 40 is interposed between the first covering portion 51 of the second path regulating member 50 and the outer surface of the exterior member 30, and the third path regulating member 60 is interposed between the second covering portion 52 of the second path regulating member 50 and the outer surface of the exterior member 30. This allows the first path regulating member 40 to fill the gap between the inner surface of the first covering portion 51 and the outer surface of the exterior member 30, and the third path regulating member 60 to fill the gap between the inner surface of the second covering portion 52 and the outer surface of the exterior member 30. This makes it possible to suitably prevent the length direction of the second path regulating member 50 from being inclined obliquely with respect to the length direction of the exterior member 30. As a result, the second path regulating member 50 can be stably attached to the outer periphery side of the exterior member 30 via the first path regulating member 40 and the third path regulating member 60.

[0073] (6) The third path regulating member 60 has a structure having the same cross-sectional shape as the first path regulating member 40. According to this configuration, the first path regulating member 40 is interposed between the inner surface of the first covering portion 51 and the outer surface of the exterior member 30, and the third path regulating member 60 having the same cross-sectional shape as the first path regulating member 40 is interposed between the inner surface of the second covering portion 52 and the outer surface of the exterior member 30. This allows members having the same structure to be interposed between the first covering portion 51 and the second covering portion 52 and the exterior member 30. Therefore, the first path regulating member 40 and the third path regulating member 60 having the same cross-sectional shape can fill the gap between the inner surface of the first covering portion 51 and the outer surface of the exterior member 30 and the gap between the inner surface of the second covering portion 52 and the outer surface of the exterior member 30 in the same manner. Therefore, it is possible to more suitably suppress the second path regulating member 50 from being inclined obliquely with respect to the length direction of the exterior member 30. As a result, the second path regulating member 50 can be attached to the outer periphery side of the exterior member 30 in a state in which the length direction of the second path regulating member 50 extends parallel to the length direction of the exterior member 30. This allows the second path regulating member 50 to be attached more stably to the outer periphery side of the exterior member 30 via the first path regulating member 40 and the third path regulating member 60.

[0074] (7) Furthermore, the third path regulating member 60 can be attached later to the outer periphery of the exterior member 30, similar to the first path regulating member 40. As a result, the workability of assembling the wire harness 10 can be improved.

[0075] (8) The third path regulating member 60 that fills the gap between the inner surface of the second covering portion 52 and the outer surface of the exterior member 30 is formed to be shorter than the first path regulating member 40. This prevents the third path regulating member 60 from being unnecessarily long, thereby preventing an increase in the material cost of the third path regulating member 60. This prevents an increase in the manufacturing cost of the wire harness 10.

[0076] (9) The first fixing member 71 fixes the first covering portion 51 of the second path regulating member 50 to the outer periphery of the first path regulating member 40. Therefore, for example, after adjusting the overlapping width between the first path regulating member 40 and the second path regulating member 50, the first covering portion 51 can be fixed to the first path regulating member 40 by the first fixing member 71. This makes it possible to suppress movement of the second path regulating member 50 relative to the first path regulating member 40 in the length direction of the wire harness main body 11. As a result, it is possible to suitably suppress a change in the overall length of the first path regulating member 40 and the second path regulating member 50 after adjusting the overlapping width between the first path regulating member 40 and the second path regulating member 50.

[0077] (10) The end of the first path regulating member 40 exposed from the second path regulating member 50 in the longitudinal direction is fixed to the outer periphery of the exterior member 30 by the second fixing member 72, and the second covering portion 52 is fixed to the outer periphery of the exterior member 30 by the third fixing member 73. This suppresses movement of the first path regulating member 40 and the second path regulating member 50 relative to the exterior member 30 in the longitudinal direction of the wire harness main body 11. This suppresses positional deviation of the first path regulating member 40 and the second path regulating member 50 relative to the exterior member 30 in the longitudinal direction of the wire harness main body 11, thereby improving the positional accuracy of the first path regulating member 40 and the second path regulating member 50 relative to the exterior member 30. As a result, the first path regulating member 40 and the second path regulating member 50 can be suitably disposed at a desired position of the wire harness main body 11, here, at the straight portion 11A, and the path of the straight portion 11A can be suitably restricted by the first path regulating member 40 and the second path regulating member 50. In other words, it is possible to suitably prevent the installation positions of the first path restricting member 40 and the second path restricting member 50 relative to the wire harness main body 11 from deviating from the straight portion 11A.

[0078] (11) The first path regulating member 40 has a first 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 contact the outer surface of the exterior member 30. The first protruding portion 45 can hold the exterior member 30 from the outside of the exterior member 30, for example. This can suitably prevent the first path regulating member 40 from being detached from the exterior member 30 through the first insertion opening 42. The second path regulating member 50 has a second protruding portion 57 that protrudes from the inner surface of at least one of the third end portion 55 and the fourth end portion 56 and can contact the outer surface of the first path regulating member 40. The second protruding portion 57 can hold the first path regulating member 40 from the outside of the first path regulating member 40, for example. This can suitably prevent the second path regulating member 50 from being detached from the first path regulating member 40 through the second insertion opening 54.

[0079] (12) The recess 47 provided on the outer surface of the first main body 41 and the second protrusion 57 provided on the inner surface of the second main body 53 are engaged with each other in the circumferential direction of the wire harness main body 11. This suppresses relative movement of the second path regulating member 50 with respect to the first path regulating member 40 in the circumferential direction of the wire harness main body 11. That is, the recess 47 and the second protrusion 57 are engaged with each other, so that the second path regulating member 50 can be prevented from rotating in the circumferential direction with respect to the first path regulating member 40. Therefore, the second path regulating member 50 can be prevented from being displaced with respect to the first path regulating member 40 in the circumferential direction of the wire harness main body 11, and the positional accuracy of the second path regulating member 50 with respect to the first path regulating member 40 can be improved.

[0080] (Other embodiments) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.

[0081] In the above embodiment, the second path regulation member 50 is attached to the first path regulation member 40 so that the orientation of the second insertion opening 54 is different from the orientation of the first insertion opening 42, but this is not limited to the above.

[0082] For example, as shown in FIG. 8, the second path regulating member 50 may be attached to the first path regulating member 40 so that the orientation of the second insertion opening 54 coincides with the orientation of the first insertion opening 42. In this modification, the first insertion opening 42 of the first path regulating member 40 and the second insertion opening 54 of the second path regulating member 50 open in the same direction (upward in the figure) along the radial direction of the exterior member 30. For example, the first insertion opening 42 and the second insertion opening 54 are provided overlapping in the radial direction of the exterior member 30. Therefore, the outer surface of the exterior member 30 exposed from the first insertion opening 42 is also exposed from the second insertion opening 54. The second protrusion 57 of this modification is provided, for example, inside the first insertion opening 42. The second protrusion 57 is capable of contacting at least one of the first end 43 and the second end 44 in the circumferential direction of the wire harness main body 11. For example, the second protrusion 57 provided at the third end 55 is in contact with the first end 43. The second protrusion 57 provided at the third end 55 is in contact with, for example, the tip 43A of the first end 43. For example, the second protrusion 57 provided at the fourth end 56 is in contact with the second end 44. The second protrusion 57 provided at the fourth end 56 is in contact with the tip 44A of the second end 44. In the configuration shown in FIG. 8, the second protrusion 57 is not in contact with the outer surface of the exterior member 30, but the second protrusion 57 may be configured to be in contact with the outer surface of the exterior member 30.

[0083] According to this configuration, the second protruding portion 57 of the second path regulating member 50 can come into contact with at least one of the first end portion 43 and the second end portion 44 that form the first insertion opening 42 in the circumferential direction of the wire harness main body 11. Therefore, the second protruding portion 57 is engaged with the first end portion 43 or the second end portion 44 in the circumferential direction of the wire harness main body 11. This makes it possible to suitably suppress the second path regulating member 50 from rotating in the circumferential direction relative to the first path regulating member 40.

[0084] The structure of the first path regulating member 40 in the above embodiment can be modified as appropriate. For example, as long as the first path regulating member 40 has a first main body portion 41 and a first insertion opening 42 and has a structure that allows it to be attached to the outer periphery of the exterior member 30, other structures are not particularly limited.

[0085] In the above embodiment, the retaining protrusions 46 are provided on the inner surface of the portion of the first main body 41 in the circumferential direction where the recesses 47 are formed, but this is not limited to this. For example, the retaining protrusions 46 and the recesses 47 may be provided at positions offset from each other in the circumferential direction of the first main body 41.

[0086] In the above embodiment, each of the retaining protrusions 46 is formed to extend over the entire length of the first main body portion 41 in the longitudinal direction, but is not limited thereto. For example, each of the retaining protrusions 46 may be provided partially in the longitudinal direction of the first path regulating member 40.

[0087] At least one of the two retaining protrusions 46 may be omitted. For example, as shown in Fig. 8, both of the two retaining protrusions 46 may be omitted. A protruding portion may be provided that protrudes from the outer surface of the first main body portion 41 toward the second path regulating member 50. For example, the protruding portion may be formed to be able to engage with the second protruding portion 57 of the second path regulating member 50 in the circumferential direction of the wire harness main body 11.

[0088] In the above embodiment, each recess 47 is formed to extend over the entire length of the first main body portion 41 in the longitudinal direction, but is not limited thereto. For example, each recess 47 may be provided partially in the longitudinal direction of the first main body portion 41.

[0089] At least one of the two recesses 47 may be omitted. For example, as shown in Fig. 8, both of the two recesses 47 may be omitted. Each of the first protrusions 45 may be provided at a position farther from the first insertion opening 42 than the tips 43A and 44A in the circumferential direction of the first path regulating member 40.

[0090] In the above embodiment, each of the first protrusions 45 is formed to extend over the entire length of the first main body portion 41 in the longitudinal direction, but is not limited thereto. For example, each of the first protrusions 45 may be provided partially in the longitudinal direction of the first path regulating member 40.

[0091] At least one of the two first protrusions 45 may be omitted. The radial thickness of the first main body portion 41 may be configured to vary in the circumferential direction. The structure of the third path regulating member 60 in the above embodiment can be modified as appropriate, similar to the first path regulating member 40.

[0092] In the above embodiment, the third path regulating member 60 is formed to be shorter than the first path regulating member 40 in the length direction of the wire harness main body 11, but is not limited thereto. For example, the third path regulating member 60 may be formed to be the same length as the first path regulating member 40 in the length direction of the wire harness main body 11, or may be formed to be longer than the first path regulating member 40.

[0093] In the above embodiment, the second path regulating member 50 is attached to the third path regulating member 60 such that a portion of the third path regulating member 60 in the longitudinal direction is exposed from the second path regulating member 50, but this is not limiting. For example, the second path regulating member 50 may be attached to the third path regulating member 60 such that the outer periphery of the third path regulating member 60 is covered over the entire length of the third path regulating member 60 in the longitudinal direction.

[0094] In the above embodiment, the cross-sectional shape of the third path regulating member 60 is the same as that of the first path regulating member 40, but is not limited to this. For example, the cross-sectional shape of the first path regulating member 40 and the cross-sectional shape of the third path regulating member 60 may be different from each other.

[0095] In the above embodiment, the third path regulating member 60 is embodied as the attachment member interposed between the inner surface of the second covering portion 52 and the outer surface of the exterior member 30, but the present invention is not limited to this. For example, the attachment member may be embodied as a tape member that covers the entire outer periphery of the exterior member 30 in the circumferential direction. In this case, the tape member is, for example, wrapped around the outer surface of the exterior member 30 until the gap between the inner surface of the second covering portion 52 and the outer surface of the exterior member 30 is filled.

[0096] The third path regulating member 60 used as the mounting member in the above embodiment may be omitted. The structure of the second path regulating member 50 in the above embodiment can be appropriately changed. For example, as long as the second path regulating member 50 has the second main body portion 53 and the second insertion opening 54, is structured to be attachable to the outer periphery of the first path regulating member 40, and is structured to be slidable on the outer periphery of the first path regulating member 40, other structures are not particularly limited.

[0097] Each of the second protrusions 57 may be provided at a position farther from the second insertion opening 54 in the circumferential direction of the second path regulating member 50 than the tips 55A and 56A. In the above embodiment, each of the second protrusions 57 is formed to extend over the entire length of the second main body portion 53 in the longitudinal direction, but is not limited thereto. For example, each of the second protrusions 57 may be provided partially in the longitudinal direction of the second path regulating member 50.

[0098] At least one of the two second protrusions 57 may be omitted. The radial thickness of the second main body portion 53 may be configured to vary in the circumferential direction. A protrusion may be provided that protrudes from the inner surface of the second main body portion 53 in the circumferential middle portion toward the first main body portion 41. This protrusion may be formed to fit into the recess 47, for example.

[0099] In the above embodiment, the recess 47 is formed on the outer surface of the first main body portion 41, the second protrusion 57 is formed on the inner surface of the second main body portion 53, and the recess 47 and the second protrusion 57 are configured to fit together, but the relationship of the recess and protrusion may be reversed. In this case, for example, a protrusion protruding from the outer surface of the first main body portion 41 is formed, and a recess that fits together with the protrusion is formed on the inner surface of the second main body portion 53.

[0100] The first fixing member 71 in the above embodiment may be omitted. The second fixing member 72 in the above embodiment may be omitted. The third fixing member 73 in the above embodiment may be formed to fix the second covering portion 52 to the outer periphery of the third path regulating member 60. In this case, a fourth fixing member that fixes the end of the third path regulating member 60 that is exposed from the second path regulating member 50 to the outer periphery of the exterior member 30 may be provided separately from the third fixing member 73.

[0101] The third fixing member 73 in the above embodiment may be omitted. In the above embodiment, the first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 are harder than the exterior member 30, but the present invention is not limited to this and may have a hardness equal to or less than that of the exterior member 30. In other words, the first path regulating member 40, the second path regulating member 50, and the third path regulating member 60 do not have to be harder than the exterior member 30 as long as they act to make the wire harness main body 11 less likely to bend than the wire harness main body 11 in a state in which they are not attached.

[0102] The exterior member 30 may be, for example, a metal layer containing a metal material provided on the outer surface of a corrugated tube made of resin. The exterior member 30 is not limited to a corrugated tube, and may be, for example, an exterior member that does not have the annular protrusion 31 and the annular recess 32.

[0103] The exterior member 30 may have a slit extending in the longitudinal direction of the exterior member 30 . Although each of the electric wires 21 is a high-voltage electric wire, the present invention is not limited to this. For example, each of the electric wires 21 may be a low-voltage electric wire.

[0104] In the electric wire member 20, the electromagnetic shielding member is embodied as the braided member 25, but the present invention is not limited to this. For example, the electromagnetic shielding member may be embodied as a metal foil. The braid member 25 in the electric wire member 20 may be omitted.

[0105] Although the electric wire member 20 includes two electric wires 21, the present invention is not limited to this. The number of electric wires 21 may be one, or three or more. The relative positions of the inverter M1 and the high-voltage battery M2 in the vehicle V are not limited to those in the above embodiment, and may be changed as appropriate depending on the vehicle configuration.

[0106] Although the multiple on-board devices electrically connected by the wire harness 10 are embodied as the inverter M1 and the high-voltage battery M2, the multiple on-board devices electrically connected by the wire harness 10 are not limited to this. The multiple on-board devices electrically connected by the wire harness 10 are not particularly limited as long as they are electrical devices mounted on the vehicle V.

[0107] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is indicated by the claims, not by the above meaning, and is intended to include all modifications within the meaning and scope of the claims.
