[0021] [Description of embodiments of this disclosure]

[0022] First, embodiments of this disclosure will be described.

[0023] [1] The wire harness of this disclosure comprises: a wire harness body having a wire member and an outer member surrounding the outer periphery of the wire member; a first path limiting member mounted on the outer periphery of the outer member for limiting the path of the wire harness body; and a second path limiting member mounted on the outer periphery of the first path limiting member for limiting the path of the wire harness body, the second path limiting member covering a portion of the outer periphery of the first path limiting member in the longitudinal direction, and covering the outer periphery of the outer member disposed at a position offset relative to the first path limiting member in the longitudinal direction of the wire harness body and exposed from the first path limiting member, the first path limiting member having: a first The first body portion covers a portion of the outer periphery of the outer component; and the second insertion port opens in a direction orthogonal to the length direction of the first body portion and extends along the entire length of the first body portion. The second path limiting member has: a second body portion covering a portion of the outer periphery of the first path limiting member and a portion of the outer periphery of the outer component; and a second insertion port opening in a direction orthogonal to the length direction of the second body portion and extending along the entire length of the second body portion. The second path limiting member is slidable along the length direction of the harness body on the outer periphery of the first path limiting member.

[0024] According to this structure, in the length direction of the wire harness body, a portion of the length direction of the first path limiting member overlaps with a portion of the length direction of the second path limiting member. Furthermore, the second path limiting member covers the outer periphery of a portion of the length direction of the first path limiting member, and also covers the outer periphery of an outer component located at a position offset from the first path limiting member in the length direction of the wire harness body. Moreover, the second path limiting member is capable of sliding relative to the first path limiting member along the length direction of the wire harness body on the outer periphery of the first path limiting member. Therefore, by allowing the second path limiting member to slide relative to the first path limiting member in the length direction of the wire harness body, the overlap width between the first and second path limiting members can be easily adjusted. By adjusting this overlap width, the overall length of the first and second path limiting members in the length direction of the wire harness body can be easily adjusted. That is, by adjusting the overlap width between the first and second path limiting members, the length of the section where the path is limited by the first and second path limiting members can be easily adjusted. Therefore, even if the length of the path restriction section changes along with the specifications of the wiring path of the main body of the wire harness, the aforementioned specification change can be easily addressed by adjusting the overlap width of the first path restriction member and the second path restriction member.

[0025] [2] Preferably, it also includes a mounting member, which is disposed separately from the first path limiting member in the length direction of the wire harness body and mounted on the outer periphery of the outer component. The second path limiting member is mounted from one end of the first path limiting member in the length direction to the mounting member. The second path limiting member has a first covering portion covering the outer periphery of the first path limiting member and a second covering portion covering the outer periphery of the mounting member. According to this structure, the first path limiting member is sandwiched between the first covering portion of the second path limiting member and the outer surface of the outer component, and the mounting member is sandwiched between the second covering portion of the second path limiting member and the outer surface of the outer component. Thus, the gap between the inner surface of the first covering portion and the outer surface of the outer component is filled by the first path limiting member, and the gap between the inner surface of the second covering portion and the outer surface of the outer component is filled by the mounting member. As a result, the second path limiting member can be stably mounted on the outer periphery of the outer component via the first path limiting member and the mounting member.

[0026] [3] Preferably, the mounting member is a third path limiting member having the same cross-sectional shape as the first path limiting member. According to this structure, the first path limiting member is sandwiched between the inner surface of the first covering portion and the outer surface of the outer component, and the third path limiting member having the same cross-sectional shape as the first path limiting member is sandwiched between the inner surface of the second covering portion and the outer surface of the outer component. Thus, members with the same structure can be sandwiched between the first and second covering portions and the outer component. Therefore, the second path limiting member can be more stably mounted to the outer periphery of the outer component via the first and third path limiting members.

[0027] [4] Preferably, the mounting member is shorter than the first path limiting member in the length direction of the wire harness body. According to this structure, the mounting member that fills the gap between the inner surface of the second covering portion and the outer surface of the outer mounting member is formed to be shorter than the first path limiting member. Therefore, it is possible to prevent the mounting member from unnecessarily becoming too long, and thus, it is possible to prevent an increase in the material cost of the mounting member. Consequently, it is possible to prevent an increase in the manufacturing cost of the wire harness.

[0028] [5] Preferably, it also includes a first fixing member that fixes the first covering portion of the second path limiting member to the outer periphery of the first path limiting member. According to this structure, for example, after adjusting the overlap width between the first and second path limiting members, the first covering portion can be fixed to the first path limiting member by the first fixing member. Thus, changes in the overall length of the first and second path limiting members after adjusting the overlap width can be appropriately suppressed.

[0029] [6] Preferably, it further comprises: a second fixing member that fixes the end of the first path limiting member protruding from the second path limiting member in the longitudinal direction to the outer periphery of the outer component; and a third fixing member that fixes the second covering portion of the second path limiting member to the outer periphery of the outer component. According to this structure, movement of the first and second path limiting members relative to the outer component in the longitudinal direction of the wire harness body is suppressed. Therefore, positional offset of the first and second path limiting members relative to the outer component in the longitudinal direction of the wire harness body can be suppressed, and the positional accuracy of the first and second path limiting members relative to the outer component can be improved.

[0030] [7] Preferably, the first path limiting member has: a first end and a second end, which are the two circumferential ends of the first body portion and form the first insertion port; and a first protrusion that protrudes from the inner surface of at least one of the first end and the second end and is capable of contacting the outer surface of the outer component. The second path limiting member has: a third end and a fourth end, which are the two circumferential ends of the second body portion and form the second insertion port; and a second protrusion that protrudes from the inner surface of at least one of the third end and the fourth end and is capable of contacting the outer surface of the first path limiting member. According to this structure, the first path limiting member has a first protrusion that protrudes from the inner surface of at least one of the first end and the second end and is capable of contacting the outer surface of the outer component. Through this first protrusion, for example, the outer component can be pressed from the outside of the outer component. Therefore, it is possible to appropriately prevent the first path limiting member from disengaging from the outer component that has passed through the first insertion port. Furthermore, the second path limiting member has a second protrusion that protrudes from the inner surface of at least one of the third and fourth ends and is capable of contacting the outer surface of the first path limiting member. Through this second protrusion, for example, the first path limiting member can be pressed from the outside. Therefore, it is possible to appropriately prevent the second path limiting member from disengaging from the first path limiting member that has passed through the second insertion port.

[0031] [8] Preferably, the second path limiting member is installed on the outer periphery of the first path limiting member with the orientation of the second insertion port different from that of the first insertion port. The first path limiting member has a recess recessed from the outer surface of the first main body, and the second protrusion can engage with the recess and engage with the recess in the circumferential direction of the wire harness body. According to this structure, the recess provided on the outer surface of the first main body and the second protrusion provided on the inner surface of the second main body engage with each other in the circumferential direction of the wire harness body by the recess and the second protrusion engaging with each other. Thus, relative movement of the second path limiting member relative to the first path limiting member in the circumferential direction of the wire harness body can be suppressed. That is, rotation of the second path limiting member relative to the first path limiting member in the circumferential direction can be suppressed.

[0032] [9] Preferably, the second path limiting member is mounted on the outer periphery of the first path limiting member such that the orientation of the second insertion port is the same as that of the first insertion port, the second protrusion is disposed inside the first insertion port, and can contact at least one of the first end and the second end in the circumferential direction of the wire harness body. According to this structure, the second protrusion of the second path limiting member is disposed inside the first insertion port, and can contact at least one of the first end and the second end forming the first insertion port in the circumferential direction of the wire harness body. Therefore, in the circumferential direction of the wire harness body, the second protrusion is engaged with the first end or the second end. Thus, circumferential rotation of the second path limiting member relative to the first path limiting member can be appropriately suppressed.

[0033] [Details of the embodiments disclosed herein]

[0034] Hereinafter, specific examples of the wire harness of this disclosure will be described with reference to the accompanying drawings. In each drawing, for ease of explanation, some parts of the structure are sometimes exaggerated or simplified. Furthermore, the dimensional ratios of the various parts may differ in different drawings. The terms "orthogonal," "parallel," or "full length" in this specification include not only strictly orthogonal, parallel, or full-length cases, but also generally orthogonal, parallel, or full-length cases within the scope of their effect in this embodiment. Additionally, in this specification, "same" includes not only cases where they are exactly the same, but also cases where the comparison objects differ slightly due to dimensional tolerances, etc. Furthermore, the term "cylindrical" as used in this specification includes not only cases where the circumferential wall is continuously formed over the entire circumference, but also cases where multiple components are combined to form a cylindrical shape, or cases where a slit is present in a portion of the circumference, such as a C-shape. Furthermore, the shape of "cylindrical" includes, but is not limited to, circles, ellipses, and polygons with pointed or rounded corners. Furthermore, the term "ring-shaped" as used in this specification sometimes refers to any construction forming a ring, a continuous shape without ends, or a generally ring-shaped construction with gaps, such as a C-shape. Additionally, the shape of "ring-shaped" includes circles, ellipses, and polygons with sharp or rounded corners, but is not limited thereto. Moreover, the invention is not limited to these examples, as shown in the claims, and includes all modifications within the meaning and scope equivalent to the claims.

[0035] (Overall structure of wire harness 10)

[0036] Figure 1The wiring harness 10 shown is, for example, mounted in a vehicle V such as a hybrid vehicle or an electric vehicle. The wiring harness 10 electrically connects two or more on-board devices to each other. These on-board devices are electronic devices mounted in the vehicle V. For example, the wiring harness 10 electrically connects an inverter M1 located at the front of the vehicle V to a high-voltage battery M2 located at the rear of the vehicle V, beyond the inverter M1. The wiring harness 10 is, for example, formed as a long strip extending along the longitudinal direction of the vehicle V. For example, the wiring harness 10 is routed through the vehicle V, such as under the floor or outside the vehicle body, along the middle portion of its length.

[0037] Inverter M1 is connected, for example, to a wheel drive motor (not shown) that serves as the power source for the vehicle. Inverter M1 generates alternating current (AC) power from the DC power of high-voltage battery M2 and supplies this AC power to the motor. High-voltage battery M2 is, for example, a battery capable of supplying several hundred volts.

[0038] The wiring harness 10 has a wiring harness body 11. The wiring harness body 11 has a wire member 20 and a cylindrical outer casing 30 surrounding the outer periphery of the wire member 20. The wiring harness 10 has connectors C1 and C2 installed at both ends of the wire member 20. One end of the wire member 20 in the longitudinal direction is connected to the inverter M1 via connector C1, and the other end of the wire member 20 in the longitudinal direction is connected to the high-voltage battery M2 via connector C2.

[0039] like Figure 2 As shown, the wiring harness 10 has a first path limiting member 40 mounted on the outer periphery of the outer component 30, a second path limiting member 50 mounted on the outer periphery of the first path limiting member 40, and a third path limiting member 60 mounted on the outer periphery of the outer component 30. The first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 limit the wiring path of the wiring harness body 11. Furthermore, in Figure 1 The illustrations of the first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 are omitted.

[0040] (Structure of electrical component 20)

[0041] like Figures 3-5 As shown, the wire component 20 has, for example, one or more wires 21 (two in this embodiment) and a braided component 25 that surrounds the periphery of the multiple wires 21.

[0042] Each wire 21 is a sheathed wire, comprising a conductive core wire 22 and an insulating sheath 23 surrounding the core wire 22 and providing insulation. Each wire 21 is, for example, a high-voltage wire capable of handling high voltage / high current. Each wire 21 can be, for example, an unshielded wire without electromagnetic shielding, or a shielded wire with electromagnetic shielding. In this embodiment, each wire 21 is an unshielded wire.

[0043] As the core wire 22, for example, a twisted wire formed by twisting multiple bare metal wires together or a single-core wire composed of a single conductor can be used. As a single-core wire, for example, a cylindrical conductor composed of a single metal rod with a solid internal structure or a tubular conductor with a hollow internal structure can be used. As the core wire 22, twisted wire, cylindrical conductor, or tubular conductor can also be combined. As the material of the core wire 22, for example, copper-based or aluminum-based metal materials can be used.

[0044] The insulating sheath 23 covers the outer circumferential surface of the core wire 22, for example, over the entire circumferential direction. The insulating sheath 23 is, for example, made of an insulating resin material.

[0045] The cross-sectional shape obtained by cutting the wires 21 with a plane orthogonal to their length direction, i.e., the cross-sectional shape of each wire 21, can be formed into any shape. For example, the cross-sectional shape of each wire 21 can be formed into a circle, a semi-circle, a polygon, a square, a flat shape, etc. In this embodiment, the cross-sectional shape of each wire 21 is formed into a circle.

[0046] The braided member 25 is, for example, formed as a cylindrical shape that integrally surrounds the outer periphery of the plurality of wires 21. As the braided member 25, for example, a braided wire made by braiding multiple bare metal wires, or a braided wire made by braiding a combination of bare metal wires and resin wires, can be used. As the material for the bare metal wires, for example, copper-based or aluminum-based metal materials can be used. The two ends of the braided member 25 in the longitudinal direction are, for example, at connectors C1 and C2 (see reference). Figure 1 (e.g., grounded connection, which is omitted from the diagram).

[0047] (Structure of external component 30)

[0048] like Figure 5 As shown, the outer casing 30 is formed as a cylinder surrounding the outer periphery of the wire component 20 over its entire circumferential range. In this embodiment, the outer casing 30 is formed as a cylinder. The outer casing 30 is, for example, sealed over its entire circumferential range. The outer casing 30, for example, has the function of protecting the wire component 20 from damage by flying objects or water droplets.

[0049] The outer component 30 is flexible, for example, and can be easily bent. Examples of flexible outer components 30 include resin bellows or rubber waterproof covers. In this embodiment, the outer component 30 is a resin bellows with a serpentine structure in which annular protrusions 31 and annular recesses 32 are alternately connected along the length of the outer component 30. The annular protrusions 31 and annular recesses 32 are each formed, for example, as annularities that encircle the circumference of the outer component 30 once. As the material of the outer component 30, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used, for example.

[0050] (The structure of the first path limiting member 40, the second path limiting member 50, and the third path limiting member 60)

[0051] like Figure 2 As shown, the first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 are each partially disposed along the length direction of the wire harness body 11. For example, the straight portion 11A of the first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 restricts the path of the wire harness body 11. Here, the straight portion 11A is the portion of the wire harness body 11 that extends straight in one direction. The first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 hold the outer member 30 in the straight portion 11A. The first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 are, for example, more rigid than the outer member 30. The first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 have a rigidity that makes them difficult to bend in a direction orthogonal to the length direction of the wire harness body 11 compared to the outer member 30. For example, the first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 assist the external member 30 to prevent the wire harness body 11 from deflecting from the desired path due to its own weight. For example, the external member 30 is less prone to bending when these path limiting members are installed compared to the state without the first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 installed.

[0052] Along the length of the harness body 11, the first path limiting member 40 and the third path limiting member 60 are disposed separately from each other. In other words, along the length of the harness body 11, between the first path limiting member 40 and the third path limiting member 60, the outer surface of the outer component 30 protrudes from the first path limiting member 40 and the third path limiting member 60. The second path limiting member 50 covers a portion of the outer periphery of the first path limiting member 40 along its length, and also covers the outer periphery of the outer component 30 disposed in the length of the harness body 11 at a position offset from the first path limiting member 40 and protruding from the first path limiting member 40. The second path limiting member 50 is capable of sliding along the outer periphery of the first path limiting member 40 in the length of the harness body 11. That is, the second path limiting member 50 is capable of sliding relative to the first path limiting member 40 in the length of the harness body 11.

[0053] In this embodiment, the second path limiting member 50 is disposed along the length of the harness body 11, extending from one end of the first path limiting member 40 along its length to the third path limiting member 60. Here, the second path limiting member 50 has a first covering portion 51 covering the outer periphery of the first path limiting member 40 and a second covering portion 52 covering the outer periphery of the third path limiting member 60. The first covering portion 51 is disposed, for example, at one end of the second path limiting member 50 along its length. The first covering portion 51 is disposed overlapping one end of the first path limiting member 40 along its length. The second covering portion 52 is disposed, for example, at the end of the second path limiting member 50 on the side opposite to the first covering portion 51 along its length. The second covering portion 52 is disposed overlapping one end of the third path limiting member 60 along its length. In this embodiment, the second path limiting member 50 covers the outer periphery of the outer member 30 disposed between the first path limiting member 40 and the third path limiting member 60 along the length of the harness body 11. That is, the portion of the second path limiting member 50 between the first covering portion 51 and the second covering portion 52 in the longitudinal direction covers the outer periphery of the outer member 30 disposed between the first path limiting member 40 and the third path limiting member 60 in the longitudinal direction of the wire harness body 11. Furthermore, in the first path limiting member 40, a portion other than one end in the longitudinal direction of the first path limiting member 40 protrudes from the second path limiting member 50. In the third path limiting member 60, for example, a portion other than one end in the longitudinal direction of the third path limiting member 60 protrudes from the second path limiting member 50.

[0054] (Structure of the first path restriction component 40)

[0055] like Figure 3As shown, the first path limiting member 40 covers a portion of the circumferential periphery of the outer member 30. The first path limiting member 40 is formed as a cylindrical shape that covers a portion of the circumferential periphery of the outer member 30. The first path limiting member 40, for example, covers an area larger than half the size of the outer periphery of the outer member 30. The cross-sectional shape of the first path limiting member 40 is generally C-shaped. The cross-sectional shape of the first path limiting member 40 is, for example, the same along its entire length. Figure 2 As shown, the first path limiting member 40 extends, for example, along the path of the straight section 11A, and is formed into a shape that extends in a straight line in one direction.

[0056] The first path limiting member 40 is made of, for example, metal or resin. In this embodiment, the first path limiting member 40 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used as the material for the first path limiting member 40. The first path limiting member 40 can be manufactured, for example, by extrusion molding or injection molding.

[0057] like Figure 3 As shown, the first path limiting member 40 has a first main body portion 41 covering a portion of the outer periphery of the outer fitting member 30, and a first insertion port 42 opening in a direction orthogonal to the length direction of the first main body portion 41. The first path limiting member 40 has two circumferential ends of the first main body portion 41, namely, a first end portion 43 and a second end portion 44 forming the first insertion port 42.

[0058] The first main body portion 41 constitutes the main part of the first path limiting member 40. The radial thickness of the first main body portion 41 is, for example, the same in the circumferential direction of the first path limiting member 40. The cross-sectional shape of the first main body portion 41 is, for example, formed along the outer surface of the outer member 30. The cross-sectional shape of the first main body portion 41 is, for example, formed as an arc.

[0059] The first end 43 and the second end 44 are disposed on opposite sides of each other in the circumferential direction of the first main body 41. The first end 43 and the second end 44 are disposed separately from each other in the circumferential direction of the first main body 41, separated by the first insertion port 42. In other words, in the circumferential direction of the first path limiting member 40, the gap between the first end 43 and the second end 44 constitutes the first insertion port 42. Thus, the first path limiting member 40 is formed in a C-shape with the first insertion port 42 in a portion of the circumferential direction of the first main body 41.

[0060] The opening width of the first insertion port 42, i.e., the shortest distance between the first end 43 and the second end 44, is, for example, smaller than the outer diameter of the outer component 30. Figure 5As shown, the first insertion port 42 extends along the entire length of the first main body portion 41. That is, the first insertion port 42 is formed to open in a direction orthogonal to the length direction of the first main body portion 41, and to open at both ends of the length direction of the first main body portion 41.

[0061] By inserting the outer component 30 into the first insertion port 42 in a direction orthogonal to the length direction of the first path limiting member 40, the first path limiting member 40 undergoes elastic deformation, increasing the opening width of the first insertion port 42. After the outer component 30 is inserted into the first path limiting member 40, the first path limiting member 40 elastically returns to its original shape. Therefore, the opening width of the first insertion port 42 is smaller than the outer diameter of the outer component 30, and thus, the first path limiting member 40 is mounted to the outer periphery of the outer component 30.

[0062] like Figure 3 As shown, the first end 43 has a front end 43A. The second end 44 has a front end 44A. The front ends 43A and 44A form a first insertion port 42. When viewed from the length direction of the first path limiting member 40, the front ends 43A and 44A are formed in a curved shape. That is, the cross-sectional shape of the front ends 43A and 44A is formed in a curved shape. In this embodiment, the cross-sectional shape of the front ends 43A and 44A is formed in a semi-circular shape.

[0063] The first path limiting member 40 has, for example, a first protrusion 45 protruding from the inner surfaces of the first end 43 and the second end 44. Each first protrusion 45 protrudes toward the outer member 30 inserted into the first path limiting member 40 and is able to contact the outer surface of the outer member 30. Each first protrusion 45 contacts, for example, the outer surface of the annular protrusion 31 of the outer member 30. The two first protrusions 45 protrude from the inner surfaces of the front ends 43A and 44A, for example. The cross-sectional shape of each first protrusion 45 is, for example, formed as a curved shape. In this embodiment, the cross-sectional shape of each first protrusion 45 is formed as a semi-circular shape. Each first protrusion 45 extends along the entire length of the first path limiting member 40 in the length direction.

[0064] The first path limiting member 40 has, for example, one or more (two in this embodiment) retaining protrusions 46 protruding from the inner surface of the first main body 41. Each retaining protrusion 46 protrudes from the inner surface of the first main body 41 toward the outer member 30 and is able to contact the outer surface of the outer member 30. Each retaining protrusion 46 contacts, for example, the outer surface of the annular protrusion 31 of the outer member 30. The two retaining protrusions 46 are spaced apart from each other in the circumferential direction of the first path limiting member 40. The cross-sectional shape of each retaining protrusion 46 is formed as a curved shape. The cross-sectional shape of each retaining protrusion 46 in this embodiment is, for example, formed as a semi-circular shape. Each retaining protrusion 46 extends along the entire length of the first path limiting member 40 in the length direction.

[0065] Each of the first protrusions 45 and each of the retaining protrusions 46 presses against the outer member 30 from the outside of the outer member 30, for example. The outer member 30 is elastically held, for example, by each of the first protrusions 45 and each of the retaining protrusions 46. As a result, the connection between the first path limiting member 40 and the outer member 30 becomes secure. Therefore, movement of the first path limiting member 40, which is mounted on the outer periphery of the outer member 30, in the longitudinal direction of the outer member 30 is suppressed.

[0066] Since each of the first protrusions 45 and each of the retaining protrusions 46 is in contact with the outer surface of the outer component 30, a gap is generated between the inner surface of the first main body portion 41 and the outer surface of the outer component 30. This gap is generated along the entire length of the first path limiting member 40 in the longitudinal direction.

[0067] The first path limiting member 40 has, for example, one or more (two in this embodiment) recesses 47 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 where it overlaps with each retaining protrusion 46 in the radial direction of the first path limiting member 40. Each recess 47 is formed to be recessed from the outer surface of the first main body portion 41 to the radially inward side of the first path limiting 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 to be curved. In this embodiment, the cross-sectional shape of each recess 47 is formed to be semi-circular. Figure 5 As shown, each recess 47 extends, for example, along the length direction of the wire harness body 11. Each recess 47 extends, for example, along the length direction of the first body portion 41, over the entire length of the first body portion 41.

[0068] (Structure of the third path restriction member 60)

[0069] like Figure 4As shown, the third path limiting member 60 covers a portion of the circumferential direction of the outer member 30. The third path limiting member 60 is formed as a cylinder that covers a portion of the circumferential direction of the outer member 30. The third path limiting member 60, for example, covers an area larger than half the circumference of the outer member 30. The cross-sectional shape of the third path limiting member 60 is generally C-shaped. The cross-sectional shape of the third path limiting member 60 is, for example, the same along its entire length. The third path limiting member 60 of this embodiment has the same cross-sectional shape as the first path limiting member 40. Therefore, in the third path limiting member 60, the same reference numerals are used for structures identical to those in the first path limiting member 40, and their descriptions are omitted. Figure 2 As shown, the third path limiting member 60 extends, for example, along the path of the straight portion 11A, and is formed to extend in a straight line in one direction. In the length direction of the harness body 11, the third path limiting member 60 is shorter than the first path limiting member 40.

[0070] The third path limiting member 60 is made of, for example, metal or resin. In this embodiment, the third path limiting member 60 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used as the material for the third path limiting member 60. The third path limiting member 60 can be manufactured, for example, by extrusion molding or injection molding.

[0071] (Structure of the second path restriction component 50)

[0072] like Figure 3 and Figure 4 As shown, the second path limiting member 50 covers a portion of the circumferential direction of the outer component 30. The second path limiting member 50 is formed as a cylindrical shape that covers a portion of the circumferential direction of the outer component 30. For example, the second path limiting member 50 covers an area larger than half the size of the outer periphery of the outer component 30.

[0073] like Figure 3 As shown, the first covering portion 51 of the second path limiting member 50 covers a portion of the circumferential direction of the first path limiting member 40 in the outer periphery of the first path limiting member 40. The first covering portion 51, for example, covers an area larger than half the outer periphery of the first path limiting member 40. Figure 4 As shown, the second covering portion 52 of the second path limiting member 50 covers a portion of the circumferential direction of the third path limiting member 60 in the outer periphery of the third path limiting member 60. The second covering portion 52 covers an area larger than half the outer periphery of the third path limiting member 60.

[0074] The cross-sectional shape of the second path limiting member 50 is generally C-shaped. For example, the cross-sectional shape of the second path limiting member 50 is the same along its entire length. Figure 2 As shown, the second path limiting member 50 extends, for example, along the path of the straight section 11A, and is formed into a shape that extends in a straight line in one direction.

[0075] The second path limiting member 50 is made of, for example, metal or resin. In this embodiment, the second path limiting member 50 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used as the material for the second path limiting member 50. The second path limiting member 50 can be manufactured, for example, by extrusion molding or injection molding.

[0076] like Figure 3 As shown, the second path limiting member 50 has a second main body portion 53 covering a portion of the outer periphery of the outer fitting member 30, and a second insertion port 54 opening in a direction orthogonal to the length direction of the second main body portion 53. The second path limiting member 50 has two circumferential ends of the second main body portion 53, namely, a third end portion 55 and a fourth end portion 56 forming the second insertion port 54.

[0077] The second main body portion 53 constitutes the main part of the second path limiting member 50. The radial thickness of the second main body portion 53 is, for example, the same in the circumferential direction of the second path limiting member 50. The cross-sectional shape of the second main body portion 53 is, for example, formed along the outer surface of the outer member 30. The cross-sectional shape of the second main body portion 53 is, for example, formed along the outer surface of the first path limiting member 40. The cross-sectional shape of the second main body portion 53 is, for example, formed in an arc shape.

[0078] The third end 55 and the fourth end 56 are disposed on opposite sides of each other in the circumferential direction of the second main body 53. The third end 55 and the fourth end 56 are disposed separately from each other in the circumferential direction of the second main body 53, separated by the second insertion port 54. In other words, in the circumferential direction of the second path limiting member 50, the gap between the third end 55 and the fourth end 56 constitutes the second insertion port 54. Thus, the second path limiting member 50 is formed in a C-shape with the second insertion port 54 in a portion of the circumferential direction of the second main body 53.

[0079] The opening width of the second insertion port 54, i.e., the shortest distance between the third end 55 and the fourth end 56, is, for example, smaller than the maximum outer diameter of the first path limiting member 40. The opening width of the second insertion port 54 is, for example, smaller than the outer diameter of the outer member 30. Figure 5As shown, the second insertion port 54 extends along the length direction of the second main body portion 53. The second insertion port 54 extends along the entire length of the second main body portion 53. That is, the second insertion port 54 is formed to open in a direction orthogonal to the length direction of the second main body portion 53, and to open at both ends of the second main body portion 53 along the length direction.

[0080] The second path limiting member 50 is installed, for example, in a manner where the orientation of the second insertion port 54 is different from the orientation of the first insertion port 42, on the first path limiting member 40 and the third path limiting member 60 (see reference). Figure 4 The outer periphery of the first insertion port 42. In this embodiment, the orientation of the second insertion port 54 is set to be exactly opposite to the orientation of the first insertion port 42. That is, as shown... Figure 3 As shown, the orientation of the first insertion port 42 and the orientation of the second insertion port 54 are set to be opposite to each other in the radial direction of the outer fitting member 30. In other words, the first insertion port 42 and the second insertion port 54 open in opposite directions in the radial direction of the outer fitting member 30. Furthermore, the second main body portion 53, for example, covers the first insertion port 42. The second main body portion 53, for example, covers the outer periphery of the outer fitting member 30 exposed from the first insertion port 42.

[0081] By inserting the outer member 30 and the first path limiting member 40 into the second insertion port 54 from a direction orthogonal to the length direction of the second path limiting member 50, the second path limiting member 50 undergoes elastic deformation, increasing the opening width of the second insertion port 54. After the outer member 30 and the first path limiting member 40 are inserted into the interior of the second path limiting member 50, the second path limiting member 50 elastically returns to its original shape. Therefore, the opening width of the second insertion port 54 is smaller than the outer diameter of the first path limiting member 40, and thus, the second path limiting member 50 is mounted to the outer periphery of the first path limiting member 40. Similarly, the second path limiting member 50 is also mounted to the third path limiting member 60 (see reference). Figure 4 The periphery of ).

[0082] like Figure 3 and Figure 4 As shown, the third end 55 has a front end 55A. The fourth end 56 has a front end 56A. The front ends 55A and 56A form the second insertion port 54. The cross-sectional shape of the front ends 55A and 56A is formed into a curved shape. In this embodiment, the cross-sectional shape of the front ends 55A and 56A is formed into a semi-circular shape.

[0083] The second path limiting member 50 has, for example, a second protrusion 57 protruding from the inner surfaces of the third end 55 and the fourth end 56. Each second protrusion 57 protrudes toward the first main body portion 41 inserted into the interior of the second path limiting member 50. Each second protrusion 57 can contact the outer surface of the first main body portion 41. Each second protrusion 57 can engage with a recess 47 provided in the first main body portion 41. In other words, each recess 47 is provided, for example, in a position where it can engage with each second protrusion 57 when the second path limiting member 50 is installed with the second insertion port 54 and the first insertion port 42 facing in opposite directions. Here, when each second protrusion 57 engages with the interior of each recess 47, the side surface of each second protrusion 57 engages with the inner surface of each recess 47 in the circumferential direction of the harness body 11. Thus, movement of the second path limiting member 50 relative to the first path limiting member 40 in the circumferential direction of the harness body 11 is suppressed. Similarly, movement of the second path limiting member 50 relative to the third path limiting member 60 in the circumferential direction of the harness body 11 is suppressed. The cross-sectional shape of each second protrusion 57 is, for example, formed along the inner surface of each recess 47. The cross-sectional shape of each second protrusion 57 is, for example, formed in a curved shape. In this embodiment, the cross-sectional shape of each second protrusion 57 is formed in a semi-circular shape. Each second protrusion 57 extends, for example, along the entire length of the second path limiting member 50.

[0084] The inner diameter of the second main body portion 53 is larger than the outer diameter of the outer component 30. For example, the inner diameter of the second main body portion 53 is formed to a degree less than or equal to the outer diameter of the outer component 30, such that when the outer component 30 is inserted inward, only one of the inner surface of the second main body portion 53 and the second protrusion 57 contacts the outer surface of the outer component 30, while the other cannot contact the outer surface of the outer component 30. Therefore, for example, when the second covering portion 52 is directly mounted to the outer surface of the outer component 30, the length direction of the second path limiting member 50 is inclined in a direction intersecting the length direction of the outer component 30. In contrast, in this embodiment, a third path limiting member 60 is sandwiched between the inner surface of the second covering portion 52 and the outer surface of the outer component 30. This third path limiting member 60 fills the gap between the inner surface of the second covering portion 52 and the outer surface of the outer component 30. Therefore, the oblique tilt of the second path limiting member 50 relative to the length direction of the outer member 30 can be appropriately suppressed. As a result, the second path limiting member 50 can be stably installed on the outer periphery of the outer member 30 via the first path limiting member 40 and the third path limiting member 60.

[0085] (The structure of the first fixing member 71, the second fixing member 72, and the third fixing member 73)

[0086] like Figure 2 As shown, the wire harness 10, for example, has a first fixing member 71 that fixes the first covering portion 51 of the second path limiting member 50 to the outer periphery of the first path limiting member 40. The wire harness 10, for example, has a second fixing member 72 that fixes the end of the first path limiting member 40 protruding from the second path limiting member 50 in the longitudinal direction to the outer periphery of the outer member 30. The wire harness 10, for example, has a third fixing member 73 that fixes the second covering portion 52 of the second path limiting member 50 to the outer periphery of the outer member 30. The first fixing member 71, the second fixing member 72, and the third fixing member 73 can be, for example, made of resin or metal, such as binding tape, caulking rings, or adhesive tape. In this embodiment, the first fixing member 71, the second fixing member 72, and the third fixing member 73 are adhesive tape.

[0087] The first fixing member 71 is wound from the first covering portion 51 to the first path limiting 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 limiting member 40 exposed from the second path limiting 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 limiting member 40 within a full circumferential range. This first fixing member 71 can suppress movement of the second path limiting member 50 relative to the first path limiting member 40 in the longitudinal and circumferential directions of the harness body 11. The second fixing member 72 is wound from the outer surface of the end of the first path limiting member 40 exposed from the second path limiting member 50 at one of its two ends in the longitudinal direction to the outer surface of the outer component 30. The second fixing member 72 covers the outer periphery of the first path limiting member 40 and the outer periphery of the outer component 30 within a full circumferential range. This second fixing member 72 can suppress movement of the first path limiting member 40 relative to the outer component 30 in the longitudinal and circumferential directions of the harness body 11. The third fixing member 73 is wound from the second covering portion 52 to the outer component 30. For example, the third fixing member 73 is wound from the outer surface of the second covering portion 52 through the outer surface of the third path limiting member 60 to the outer surface of the outer component 30. The third fixing member 73 covers the outer periphery of the second path limiting member 50, the outer periphery of the third path limiting member 60, and the outer periphery of the outer component 30 over the entire circumferential direction. This third fixing member 73 can suppress movement of the second path limiting member 50 and the third path limiting member 60 relative to the outer component 30 in the length and circumferential directions of the harness body 11.

[0088] In addition, Figure 1 and Figures 3-5The illustrations of the first fixing member 71, the second fixing member 72, and the third fixing member 73 are omitted.

[0089] Next, the function of this embodiment will be explained.

[0090] Along the length of the harness body 11, a portion of the first path limiting member 40 overlaps with a portion of the second path limiting member 50. Furthermore, the second path limiting member 50 covers the outer periphery of a portion of the first path limiting member 40 along its length, and also covers the outer periphery of the outer member 30 located at a position offset from the first path limiting member 40 along the length of the harness body 11. Moreover, the second path limiting member 50 is capable of sliding along the length of the harness body 11 on the outer periphery of the first path limiting member 40. Therefore, by allowing the second path limiting member 50 to slide relative to the first path limiting member 40 along the length of the harness body 11, the overlap width between the first path limiting member 40 and the second path limiting member 50 can be easily adjusted. By adjusting this overlap width, the overall length of the first path limiting member 40 and the second path limiting member 50 along the length of the harness body 11 can be easily adjusted. That is, by adjusting the overlap width of the first path limiting member 40 and the second path limiting member 50, the length of the interval in which the path is limited by the first path limiting member 40 and the second path limiting member 50 can be easily adjusted.

[0091] And, as Figure 6 As shown, by sliding the second path limiting member 50 relative to the first path limiting member 40, the second path limiting member 50 can be configured to cover the outer periphery of the first path limiting member 40 along its entire length in the longitudinal direction. That is, the first path limiting member 40 and the second path limiting member 50 can be uniformly arranged in the longitudinal direction of the wire harness body 11. By adopting this structure, the overall length of the first path limiting member 40 and the second path limiting member 50 can be shortened, for example, during the transport of the wire harness 10. Therefore, the outer member 30 located between the second path limiting member 50 and the third path limiting member 60 can be bent during transport, thus reducing the bundle size of the wire harness 10 during transport. As a result, the increase in transport costs of the wire harness 10 can be appropriately suppressed. Furthermore, in Figure 6 In the state shown, no settings are configured. Figure 2 The first fixing member 71 is shown. Therefore, for example, after the wire harness 10 is transported, the second path limiting member 50 can slide relative to the first path limiting member 40.

[0092] like Figure 7 As shown, by means of Figure 6The state shown allows the second path limiting member 50 to slide toward the third path limiting member 60, changing the overall length of the first path limiting member 40 and the second path limiting member 50 (see the arrow in the figure). At this time, by placing the third path limiting member 60 at a position corresponding to one end of the path limiting interval, the second path limiting member 50 can be easily positioned in the length direction of the harness body 11 while the second path limiting member 50 is sliding. Furthermore, after the second path limiting member 50 slides toward the third path limiting member 60, for example, a... Figure 2 The first fixing member 71, the second fixing member 72, and the third fixing member 73 are shown.

[0093] Next, the effects of this embodiment will be explained.

[0094] (1) The second path limiting member 50 is configured to slide along the length direction of the harness body 11 on the outer periphery of the first path limiting member 40. According to this structure, the overall length of the first path limiting member 40 and the second path limiting member 50 can be easily adjusted by adjusting the overlap width of the first path limiting member 40 and the second path limiting member 50. Therefore, even if the length of the path limiting section changes due to a change in the specifications of the wiring path of the harness body 11, for example, the change in specifications can be easily addressed by adjusting the overlap width of the first path limiting member 40 and the second path limiting member 50.

[0095] (2) The first insertion port 42 of the first path limiting member 40 opens in a direction orthogonal to the length direction of the first main body 41 and extends along the entire length of the first main body 41. Therefore, after termination processing such as mounting connectors C1 and C2 to the ends of the wire member 20 along its length, the first path limiting member 40 can be installed onto the outer member 30 through the first insertion port 42. This allows for the installation of the first path limiting member 40, thereby improving the assembly workability of the wire harness 10.

[0096] (3) The second insertion port 54 of the second path limiting member 50 opens in a direction orthogonal to the length direction of the second main body 53 and extends along the entire length of the second main body 53. Therefore, the second path limiting member 50 can be attached to the outer periphery of the outer member 30 and the outer periphery of the first path limiting member 40 via the second insertion port 54. As a result, the assembly workability of the wire harness 10 can be improved.

[0097] (4) In the portion where the first path limiting member 40 and the second path limiting member 50 overlap, the first path limiting member 40 and the second path limiting member 50 are doubly mounted on the outer periphery of the outer member 30. Therefore, in the portion where the first path limiting member 40 and the second path limiting member 50 overlap, the bending rigidity of the wire harness 10 can be improved.

[0098] (5) A first path limiting member 40 is sandwiched between the first covering portion 51 of the second path limiting member 50 and the outer surface of the outer member 30, and a third path limiting member 60 is sandwiched between the second covering portion 52 of the second path limiting member 50 and the outer surface of the outer member 30. Thus, the gap between the inner surface of the first covering portion 51 and the outer surface of the outer member 30 can be filled by the first path limiting member 40, and the gap between the inner surface of the second covering portion 52 and the outer surface of the outer member 30 can be filled by the third path limiting member 60. Therefore, the oblique inclination of the length direction of the second path limiting member 50 relative to the length direction of the outer member 30 can be appropriately suppressed. As a result, the second path limiting member 50 can be stably mounted on the outer periphery of the outer member 30 via the first path limiting member 40 and the third path limiting member 60.

[0099] (6) The third path limiting member 60 is configured to have the same cross-sectional shape as the first path limiting member 40. According to this configuration, the first path limiting member 40 is sandwiched between the inner surface of the first covering portion 51 and the outer surface of the outer member 30, and the third path limiting member 60, having the same cross-sectional shape as the first path limiting member 40, is sandwiched between the inner surface of the second covering portion 52 and the outer surface of the outer member 30. Thus, members with the same configuration can be sandwiched between the first covering portion 51 and the second covering portion 52 and the outer member 30. Therefore, the gaps between the inner surface of the first covering portion 51 and the outer surface of the outer member 30, and between the inner surface of the second covering portion 52 and the outer surface of the outer member 30, can be filled in the same way by using the first path limiting member 40 and the third path limiting member 60, both having the same cross-sectional shape. Therefore, the oblique inclination of the length direction of the second path limiting member 50 relative to the length direction of the outer member 30 can be more appropriately suppressed. As a result, the second path limiting member 50 can be installed on the outer periphery of the outer component 30 while the length direction of the second path limiting member 50 extends parallel to the length direction of the outer component 30. Thus, the second path limiting member 50 can be more stably installed on the outer periphery of the outer component 30 via the first path limiting member 40 and the third path limiting member 60.

[0100] (7) Furthermore, the third path limiting member 60 can be mounted on the outer periphery of the outer member 30 in the same manner as the first path limiting member 40. As a result, the assembly workability of the wire harness 10 can be improved.

[0101] (8) The third path limiting member 60, which fills the gap between the inner surface of the second covering portion 52 and the outer surface of the outer component 30, is formed to be shorter than the first path limiting member 40. Therefore, it is possible to prevent the third path limiting member 60 from being unnecessarily long, and thus, it is possible to prevent an increase in the material cost of the third path limiting member 60. As a result, it is possible to prevent an increase in the manufacturing cost of the wire harness 10.

[0102] (9) The first covering portion 51 of the second path limiting member 50 is fixed to the outer periphery of the first path limiting member 40 by the first fixing member 71. Therefore, for example, after adjusting the overlap width between the first path limiting member 40 and the second path limiting member 50, the first covering portion 51 can be fixed to the first path limiting member 40 by the first fixing member 71. As a result, movement of the second path limiting member 50 relative to the first path limiting member 40 in the length direction of the harness body 11 can be suppressed. Consequently, changes in the overall length of the first path limiting member 40 and the second path limiting member 50 after adjusting the overlap width between the first path limiting member 40 and the second path limiting member 50 can be appropriately suppressed.

[0103] (10) The end of the first path limiting member 40 protruding from the second path limiting member 50 in the longitudinal direction is fixed to the outer periphery of the outer member 30 by the second fixing member 72, and the second covering portion 52 is fixed to the outer periphery of the outer member 30 by the third fixing member 73. This suppresses movement of the first path limiting member 40 and the second path limiting member 50 relative to the outer member 30 in the longitudinal direction of the harness body 11. Therefore, positional offset of the first path limiting member 40 and the second path limiting member 50 relative to the outer member 30 in the longitudinal direction of the harness body 11 can be suppressed, and the positional accuracy of the first path limiting member 40 and the second path limiting member 50 relative to the outer member 30 can be improved. As a result, the first path limiting member 40 and the second path limiting member 50 can be appropriately positioned at the desired location on the harness body 11, here the straight portion 11A, and the path of the straight portion 11A can be appropriately limited by the first path limiting member 40 and the second path limiting member 50. In other words, it is possible to appropriately prevent the first path limiting member 40 and the second path limiting member 50 from disengaging from the straight section 11A relative to the wiring harness body 11.

[0104] (11) The first path limiting member 40 has a first protrusion 45 that protrudes from the inner surface of at least one of the first end 43 and the second end 44 and is able to contact the outer surface of the outer member 30. Through the first protrusion 45, for example, the outer member 30 can be pressed from the outside of the outer member 30. Therefore, disengagement of the first path limiting member 40 from the outer member 30 passing through the first insertion port 42 can be appropriately suppressed. Furthermore, the second path limiting member 50 has a second protrusion 57 that protrudes from the inner surface of at least one of the third end 55 and the fourth end 56 and is able to contact the outer surface of the first path limiting member 40. Through the second protrusion 57, for example, the first path limiting member 40 can be pressed from the outside of the first path limiting member 40. Therefore, disengagement of the second path limiting member 50 from the first path limiting member 40 passing through the second insertion port 54 can be appropriately suppressed.

[0105] (12) The recesses 47 on the outer surface of the first main body 41 and the second protrusions 57 on the inner surface of the second main body 53 engage with each other in the circumferential direction of the harness body 11. This suppresses relative movement of the second path limiting member 50 relative to the first path limiting member 40 in the circumferential direction of the harness body 11. In other words, the engagement of the recesses 47 and the second protrusions 57 suppresses circumferential rotation of the second path limiting member 50 relative to the first path limiting member 40. Therefore, positional offset of the second path limiting member 50 relative to the first path limiting member 40 in the circumferential direction of the harness body 11 can be suppressed, improving the positional accuracy of the second path limiting member 50 relative to the first path limiting member 40.

[0106] (Other implementation methods)

[0107] The above embodiments can be implemented by modifications as follows. The above embodiments and the following modifications can be combined with each other to implement them to the extent that they are not technically contradictory.

[0108] • In the above embodiment, the second path limiting member 50 is installed on the first path limiting member 40 in such a way that the orientation of the second insertion port 54 is different from the orientation of the first insertion port 42, but it is not limited to this.

[0109] For example, Figure 8As shown, the second path limiting member 50 can also be configured such that the orientation of the second insertion port 54 is consistent with the orientation of the first insertion port 42. In this modified example, the first insertion port 42 of the first path limiting member 40 and the second insertion port 54 of the second path limiting member 50 open in the same direction (upper part of the figure) along the radial direction of the outer member 30. For example, the first insertion port 42 and the second insertion port 54 are arranged to overlap in the radial direction of the outer member 30. Therefore, the outer surface of the outer member 30 exposed from the first insertion port 42 is also exposed from the second insertion port 54. In this modified example, the second protrusion 57 is provided inside the first insertion port 42. The second protrusion 57 can contact at least one of the first end 43 and the second end 44 in the circumferential direction of the harness body 11. For example, the second protrusion 57 provided at the third end 55 contacts the first end 43. The second protrusion 57 located at the third end 55 contacts, for example, the front end 43A of the first end 43. For example, the second protrusion 57 located at the fourth end 56 contacts the second end 44. The second protrusion 57 located at the fourth end 56 contacts the front end 44A of the second end 44. Furthermore, in... Figure 8 In the structure shown, the second protrusion 57 does not contact the outer surface of the outer component 30, but it is not limited to this and can also be configured such that the second protrusion 57 contacts the outer surface of the outer component 30.

[0110] According to this structure, the second protrusion 57 of the second path limiting member 50 can contact at least one of the first end 43 and the second end 44 that form the first insertion port 42 in the circumferential direction of the wire harness body 11. Therefore, in the circumferential direction of the wire harness body 11, the second protrusion 57 is engaged with the first end 43 or the second end 44. Thus, the circumferential rotation of the second path limiting member 50 relative to the first path limiting member 40 can be appropriately suppressed.

[0111] • The structure of the first path limiting member 40 in the above embodiment can be appropriately modified. For example, the first path limiting member 40 only needs to have a structure that includes a first main body 41 and a first insertion port 42 and can be installed on the outer periphery of the outer component 30; other structures are not particularly limited.

[0112] In the above embodiment, each retaining protrusion 46 is provided on the inner surface of the portion of the first main body 41 in the circumferential direction where the recess 47 is formed, but it is not limited thereto. For example, it may also be provided at a position in the circumferential direction of the first main body 41 where the retaining protrusion 46 and the recess 47 are offset from each other.

[0113] In the above embodiment, each retaining protrusion 46 is formed to extend along the entire length of the first main body portion 41, but is not limited thereto. For example, each retaining protrusion 46 may also be provided partially along the length of the first path limiting member 40.

[0114] • It is also possible to omit at least one of the two retaining protrusions 46. For example, it could also be as follows: Figure 8 As shown, the two retaining protrusions 46 are omitted on both sides.

[0115] • A protrusion may also be provided that protrudes from the outer surface of the first main body 41 toward the second path limiting member 50. For example, the protrusion may be formed to engage with the second protrusion 57 of the second path limiting member 50 in the circumferential direction of the wire harness body 11.

[0116] • In the above embodiment, each recess 47 is formed to extend along the entire length of the first main body portion 41, but is not limited thereto. For example, each recess 47 may also be provided partially along the length of the first main body portion 41.

[0117] • At least one of the two recesses 47 can also be omitted. For example, it can also be as follows: Figure 8 As shown, both sides of the two recesses 47 are omitted.

[0118] Alternatively, each of the first protrusions 45 may be positioned in the circumferential direction of the first path limiting member 40 at a position further away from the first insertion port 42 than the front ends 43A and 44A.

[0119] In the above embodiment, each first protrusion 45 is formed to extend along the entire length of the first main body portion 41, but is not limited thereto. For example, each first protrusion 45 may also be provided partially along the length of the first path limiting member 40.

[0120] • At least one of the two first protrusions 45 may also be omitted.

[0121] • It can also be configured such that the radial thickness of the first main body 41 varies in the circumferential direction.

[0122] The structure of the third path limiting member 60 in the above embodiment can also be appropriately modified in the same way as the first path limiting member 40.

[0123] In the above embodiment, the third path limiting member 60 is formed to be shorter than the first path limiting member 40 in the length direction of the wire harness body 11, but it is not limited to this. For example, the third path limiting member 60 may be formed to be the same length as the first path limiting member 40 in the length direction of the wire harness body 11, or it may be formed to be longer than the first path limiting member 40.

[0124] In the above embodiment, the second path limiting member 50 is mounted to the third path limiting member 60 such that a portion of the length direction of the third path limiting member 60 is exposed from the second path limiting member 50, but this is not a limitation. For example, the second path limiting member 50 may also be mounted to the third path limiting member 60 such that it covers the outer periphery of the third path limiting member 60 along its entire length direction.

[0125] • In the above embodiment, the cross-sectional shape of the third path limiting member 60 is the same as the cross-sectional shape of the first path limiting member 40, but it is not limited to this. For example, the cross-sectional shapes of the first path limiting member 40 and the third path limiting member 60 may be different from each other.

[0126] In the above embodiment, the mounting member sandwiched between the inner surface of the second covering portion 52 and the outer surface of the outer member 30 is specifically embodied as the third path limiting member 60, but is not limited thereto. For example, the mounting member may also be embodied as a belt member that covers the outer periphery of the outer member 30 over the entire circumferential range. In this case, the belt member is, for example, wrapped around the outer surface of the outer member 30 in an overlapping manner until the gap between the inner surface of the second covering portion 52 and the outer surface of the outer member 30 is filled.

[0127] • The third path limiting member 60, which is an installation member in the above embodiment, can also be omitted.

[0128] • The structure of the second path limiting member 50 in the above embodiment can be appropriately modified. For example, the second path limiting member 50 only needs to have a structure that includes a second main body portion 53 and a second insertion port 54 and can be installed on the outer periphery of the first path limiting member 40, and has a structure that can slide on the outer periphery of the first path limiting member 40. Other structures are not particularly limited.

[0129] Alternatively, each of the second protrusions 57 may be positioned in the circumferential direction of the second path limiting member 50 at a position further away from the second insertion port 54 than the front ends 55A and 56A.

[0130] • In the above embodiment, each second protrusion 57 is formed to extend along the entire length of the second main body 53, but is not limited thereto. For example, each second protrusion 57 may also be provided partially along the length of the second path limiting member 50.

[0131] • At least one of the two second protrusions 57 can also be omitted.

[0132] • It can also be configured such that the radial thickness of the second main body 53 varies in the circumferential direction.

[0133] • A protrusion may also be provided that protrudes from the inner surface of the middle portion of the second main body 53 toward the first main body 41. The protrusion may also be formed, for example, to fit into the recess 47.

[0134] In the above embodiment, a recess 47 is formed on the outer surface of the first main body portion 41, and a second protrusion 57 is formed on the inner surface of the second main body portion 53. These recesses 47 and the second protrusion 57 are interlocked, but their interlocking relationship can also be reversed. In this case, for example, a protrusion is formed protruding from the outer surface of the first main body portion 41, and a recess that interlocks with the protrusion is formed on the inner surface of the second main body portion 53.

[0135] • The first fixing member 71 in the above embodiments can also be omitted.

[0136] • The second fixing member 72 in the above embodiments can also be omitted.

[0137] Alternatively, the third fixing member 73 in the above embodiment can be formed to fix the second covering portion 52 to the outer periphery of the third path limiting member 60. In this case, a fourth fixing member can also be provided separately from the third fixing member 73, which fixes the end of the third path limiting member 60 that protrudes from the second path limiting member 50 to the outer periphery of the outer member 30.

[0138] • The third fixing member 73 in the above embodiments can also be omitted.

[0139] In the above embodiment, the first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 are more rigid than the outer member 30, but are not limited thereto; they may also have the same or less rigidity as the outer member 30. That is, the first path limiting member 40, the second path limiting member 50, and the third path limiting member 60 only need to function in a way that makes the wire harness body 11 less prone to bending compared to the state in which they are not installed, and may not be more rigid than the outer member 30.

[0140] • The outer component 30 may also have a metal layer containing a metal material on the outer surface of the resin bellows.

[0141] • The outer component 30 is not limited to a bellows, but can also be an outer component without the annular protrusion 31 and the annular recess 32.

[0142] • The outer component 30 may also have a slit extending along the length of the outer component 30.

[0143] • Each wire 21 may be configured as a high-voltage wire, but is not limited to this; for example, each wire 21 may also be configured as a low-voltage wire.

[0144] • In the wire component 20, the electromagnetic shielding component is embodied as a braided component 25, but is not limited thereto. For example, the electromagnetic shielding component may also be embodied as a metal foil.

[0145] • The braided component 25 in the wire component 20 can also be omitted.

[0146] • The number of wires 21 constituting the wire component 20 may be two, but is not limited to this. The number of wires 21 may also be one, or three or more.

[0147] The configuration relationship between the inverter M1 and the high-voltage battery M2 in vehicle V is not limited to the above implementation method, and can be appropriately changed according to the vehicle structure.

[0148] • The multiple on-board devices electrically connected to the wiring harness 10 are specifically embodied as an inverter M1 and a high-voltage battery M2, but are not limited to these. The multiple on-board devices electrically connected to the wiring harness 10 can be any electronic devices mounted on the vehicle V, without any particular limitation.

[0149] The embodiments disclosed herein are illustrative in all respects and should not be considered limiting. The scope of the invention is defined by the claims rather than by the foregoing, and includes all modifications within the equivalent meaning and scope of the claims.
