[0021] [Description of embodiments of this disclosure]

[0022] First, the implementation methods of this disclosure are listed and explained.

[0023] [1] The wire harness disclosed herein has: a wire harness body having a wire member and an outer member surrounding the outer periphery of the wire member; a path limiting member fitted to the outer periphery of the outer member to limit the path of the wire harness body; and an assembly member fitted to a portion of the outer periphery of the path limiting member in the length direction, the path limiting member having: a first body portion covering a portion of the outer periphery of the outer member; and an insertion port opening in a direction orthogonal to the length direction of the first body portion and extending along the entire length direction of the first body portion, the path limiting member having a connecting portion connected to the assembly member, the assembly member having a covering portion covering the outer periphery of the connecting portion, the covering portion having a through hole through which the covering portion radially penetrates the outer member.

[0024] According to this structure, the connecting portion of the path limiting member and the covering portion of the assembly member are arranged overlappingly along the length of the wire harness body. In this case, the covering portion, which covers the outer periphery of the connecting portion, is provided with a through hole that radially penetrates the covering portion into the outer assembly member. Therefore, even if a liquid, such as water, is immersed between the outer surface of the connecting portion and the inner surface of the covering portion, the liquid can be discharged through the through hole to the outside of the assembly member. Thus, liquid retention between the outer surface of the connecting portion and the inner surface of the covering portion can be suppressed. Therefore, the detachment of the assembly member from the path limiting member due to the weight of the liquid retained between the outer surface of the connecting portion and the inner surface of the covering portion can be appropriately suppressed. As a result, the connection reliability between the path limiting member and the assembly member can be improved.

[0025] [2] Preferably, the through hole is provided in the circumferential direction of the covering portion that covers the outer periphery of the first main body. According to this structure, a through hole is provided in the portion of the covering portion that covers the outer periphery of the first main body. Here, liquid is more likely to accumulate between the outer surface of the first main body and the inner surface of the covering portion than between the insertion port and the inner surface of the covering portion. Therefore, by providing a through hole in the portion where liquid is more likely to accumulate, liquid can be properly discharged to the outside of the assembly member through this through hole. As a result, the assembly member can be appropriately prevented from detaching from the path-limiting member, and the connection reliability between the path-limiting member and the assembly member can be improved.

[0026] [3] Preferably, the through hole opens vertically downwards when the wiring harness is mounted on the vehicle. According to this structure, because the through hole opens vertically downwards, liquid that has seeped between the outer surface of the connector and the inner surface of the cover can be efficiently drained through the through hole to the outside of the assembly component. As a result, the assembly component can be appropriately prevented from detaching from the path-limiting member, and the connection reliability between the path-limiting member and the assembly component can be improved.

[0027] [4] Preferably, the covering portion has a limiting wall that engages with a first end face of the path limiting member in the length direction of the wire harness body. According to this structure, the first end face of the path limiting member in the length direction of the wire harness body engages with the limiting wall of the covering portion. Therefore, relative movement of the path limiting member relative to the assembly member can be suppressed in the length direction of the wire harness body. Consequently, misalignment of the path limiting member relative to the assembly member can be suppressed in the length direction of the wire harness body. As a result, the positional accuracy of the path limiting member relative to the assembly member can be improved.

[0028] [5] Preferably, the limiting wall is provided at one end of the covering portion in the length direction, the covering portion has a second end face, and the end opposite to the limiting wall at one of the two ends of the covering portion in the length direction has the second end face. The through hole is provided at a first distance away from the second end face in the length direction of the wire harness body, the first distance being a distance corresponding to the minimum insertion amount of the path limiting member required by the covering portion in the length direction of the wire harness body. According to this structure, the through hole is provided at a first distance away from the second end face in the length direction of the covering portion, and the first distance corresponds to the minimum insertion amount of the path limiting member required by the covering portion. Therefore, the through hole can be used as a hole for confirming the insertion amount of the path limiting member relative to the covering portion, specifically the insertion amount of the path limiting member in the length direction of the wire harness body. That is, even from the outside of the assembly component, the insertion amount of the path limiting member relative to the covering portion can be confirmed through the through hole. For example, when it can be confirmed through the through hole that the path limiting member is inserted into the through hole, it can be confirmed that the path limiting member is inserted at or above the minimum insertion amount required by the covering portion.

[0029] [6] Preferably, the through hole is offset toward the limiting wall side in the length direction of the covering portion. According to this structure, the through hole is provided near the limiting wall. For example, a through hole is provided near the limiting wall used as a positioning member for path limiting members in the length direction of the wire harness body. Therefore, for example, it can be confirmed through the through hole whether the path limiting member in the length direction of the wire harness body is inserted near the limiting wall.

[0030] [7] Preferably, the covering portion has a plurality of through holes arranged along the length direction of the covering portion. According to this structure, since the plurality of through holes are arranged along the length direction of the covering portion, the insertion amount of the path limiting member relative to the assembly member can be appropriately determined based on the position of the path limiting member that can be confirmed through the plurality of through holes.

[0031] [8] Preferably, the covering portion is formed as an annular ring that surrounds the outer periphery of the connecting portion and the outer periphery of the outer component to which the connecting portion is assembled, and the covering portion has a second main body portion that covers a portion of the outer periphery of the first main body portion, and a cover connected to the second main body portion. According to this structure, although the covering portion is annular, it is divided into a second main body portion and a cover portion, thereby allowing the assembly component including the covering portion to be subsequently installed on the path limiting member and the outer component. This improves the assembly workability of the wire harness.

[0032] [9] Preferably, the path limiting member has a first end and a second end forming the insertion port, the first end and the second end being the two circumferential ends of the first main body, and the covering portion has a protrusion that protrudes from the inner surface of the cover portion toward the insertion port, the protrusion being able to contact at least one of the first end and the second end in the circumferential direction of the path limiting member. According to this structure, the protrusion of the covering portion is able to contact at least one of the first end and the second end forming the insertion port in the circumferential direction of the path limiting member. Therefore, in the circumferential direction of the path limiting member, the protrusion engages with either the first end or the second end. This appropriately suppresses circumferential rotation of the path limiting member relative to the covering portion.

[0033]

[10] Preferably, the outer component is a bellows having a corrugated shape in which annular protrusions and annular recesses are alternately connected in the length direction of the outer component, and the protrusions have protrusions that enter the annular recesses. According to this structure, the protrusions have protrusions that enter the annular recesses of the bellows. Therefore, movement of the bellows relative to the assembly component can be suppressed in the length direction of the bellows.

[0034]

[11] Preferably, when the path limiting member is set as the first path limiting member, the assembly member is a second path limiting member assembled on the outer periphery of the outer assembly member and limiting the path of the wire harness body. The connecting portion is provided at the end of the first path limiting member in the longitudinal direction, and the covering portion is provided at the end of the second path limiting member in the longitudinal direction. The first path limiting member limits the path of the straight portion, which is a straight part in the path of the wire harness body, and the second path limiting member limits the path of the bent portion, which is a bent part in the path of the wire harness body. According to this structure, the path of the straight portion is limited by the first path limiting member, and the path of the bent portion is limited by the second path limiting member. As a result, it is possible to prevent the path of the straight portion and the path of the bent portion from deviating from the desired path.

[0037] (Overall structure of wire harness 10)

[0038] Figure 1 The wiring harness 10 shown is, for example, mounted on 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. On-board devices are electrical devices mounted on 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 an elongated shape extending in the longitudinal direction of the vehicle V. For example, the wiring harness 10 is laid out in the vehicle V such that its middle portion passes under the floor or outside the vehicle exterior.

[0039] Inverter M1 is connected, for example, to an electric motor (not shown) that powers the drive wheels of the vehicle. Inverter M1 generates alternating current from the direct current (DC) of high-voltage battery M2 and supplies this AC power to the electric motor. High-voltage battery M2 is, for example, a battery capable of supplying several hundred volts.

[0040] 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 that surrounds the outer periphery of the wire member 20. The wiring harness 10 has connectors C1 and C2 fitted to 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.

[0041] like Figure 2 and Figure 3 As shown, the wire harness 10 has a first path limiting member 40 mounted on the outer periphery of the outer component 30 and a second path limiting member 50 mounted on the outer periphery of the outer component 30. The first path limiting member 40 and the second path limiting member 50 limit the routing path of the wire harness body 11. Furthermore, in Figure 1 The illustrations of the first path limiting member 40 and the second path limiting member 50 are omitted.

[0042] (Structure of electrical component 20)

[0043] like Figure 4 and Figure 5 As shown, the wire member 20 has, for example, one or more (two in this embodiment) wires 21 and a braided member 25 that surrounds the outer circumference of the multiple wires 21.

[0044] like Figure 4 As shown, each wire 21 is a covered wire having a core wire 22 and an insulating covering portion 23. The core wire 22 is conductive, and the insulating covering portion 23 surrounds the outer periphery of the core wire 22 and is insulating. Each wire 21 is, for example, a high-voltage wire capable of handling high voltage and high current. Each wire 21 can be, for example, an unshielded wire without its own electromagnetic shielding structure, or a shielded wire with its own electromagnetic shielding structure. In this embodiment, each wire 21 is an unshielded wire.

[0045] As the core wire 22, for example, a stranded wire made of multiple metal wires twisted together or a single-core wire made of a single conductor can be used. As a single-core wire, for example, a cylindrical conductor made of a single metal rod with a solid internal structure or a tubular conductor with a hollow internal structure can be used. Stranded wires, cylindrical conductors, and tubular conductors can also be used in combination as the core wire 22. As the material of the core wire 22, for example, copper-based or aluminum-based metal materials can be used.

[0046] The insulating covering portion 23, for example, covers the entire circumference of the outer peripheral surface of the core wire 22. The insulating covering portion 23 is, for example, made of an insulating resin material.

[0047] The cross-sectional shape of each wire 21, which is the shape of the cross section cut by a plane orthogonal to the length direction of each wire 21, can be any shape. For example, the cross-sectional shape of each wire 21 can be formed as 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 as a circle.

[0048] The braided member 25 is, for example, formed as a cylindrical shape that surrounds the outer circumference of the multiple wires 21. The braided member 25 can be, for example, a braided wire made of multiple metal wires, or a braided wire made of a combination of metal wires and resin wires. The material of the metal wires can be, for example, copper-based, aluminum-based, or other metal materials. Although not shown in the figure, the two ends of the braided member 25 in the longitudinal direction are, for example, at connectors C1 and C2 (see reference). Figure 1 Grounding in, etc.

[0049] (Structure of external component 30)

[0050] like Figure 3 As shown, the outer casing 30 is formed into a cylindrical shape that surrounds the entire circumference of the wire component 20. In this embodiment, the outer casing 30 is formed into a cylindrical shape. For example, a circumferential wall is continuously formed throughout the entire circumference of the outer casing 30. For example, the outer casing 30 is sealed throughout the entire circumference of the outer casing 30. The outer casing 30 has the function of protecting the wire component 20 from, for example, flying objects or water droplets.

[0051] The outer component 30 is flexible, for example, and can be easily bent. Examples of flexible outer components 30 include resin bellows and rubber waterproof caps. In this embodiment, the outer component 30 is a resin bellows with a corrugated structure in which annular protrusions 31 and annular recesses 32 are alternately connected along the length of the outer component 30. Each of the annular protrusions 31 and annular recesses 32 forms an annulus around the circumference of the outer component 30. As a material for the outer component 30, synthetic resins such as polyolefins, polyamides, polyesters, and ABS resins can be used. Furthermore, in Figure 1 and Figure 2 In order to simplify the accompanying drawings, the external component 30 is shown in a simplified manner.

[0052] (Structure of the first path limiting member 40 and the second path limiting member 50)

[0053] like Figure 2As shown, the first path limiting member 40 and the second path limiting member 50 each hold the outer member 30. The first path limiting member 40 and the second path limiting member 50 are, for example, more rigid than the outer member 30. The first path limiting member 40 and the second path limiting member 50 each have a rigidity that makes them less prone to bending in a direction orthogonal to the length direction of the wire harness body 11 compared to the outer member 30. Therefore, the first path limiting member 40 and the second path limiting member 50 each restrict the path of the wire harness body 11. For example, the first path limiting member 40 and the second path limiting member 50 each assist the outer member 30 so that the wire harness body 11 does not deviate from the desired path due to its own weight or other bending. The outer member 30 is, for example, less prone to bending than when the first path limiting member 40 and the second path limiting member 50 are not attached.

[0054] The first path limiting member 40 is partially provided along the length of the wire harness body 11. The first path limiting member 40 is fitted to the outer periphery of the outer member 30, for example, in a straight portion 11A, which is a straight section in the path of the wire harness body 11. The first path limiting member 40 restricts the path of the wire harness body 11 in the straight portion 11A. Here, the straight portion 11A is the portion where the path of the wire harness body 11 extends in a straight line in one direction. Furthermore, one or more first path limiting members 40 are provided according to the path of the wire harness body 11.

[0055] The second path limiting member 50 is partially provided along the length of the wire harness body 11. The second path limiting member 50 is fitted to the outer periphery of the outer member 30, for example, in a bend 11B that is a portion of the wire harness body 11 that bends in its path. The second path limiting member 50 restricts the path of the wire harness body 11 in the bend 11B. Here, the bend 11B is a portion of the wire harness body 11 where the path is bent in a two-dimensional or three-dimensional shape. Furthermore, one or more second path limiting members 50 are provided depending on the path of the wire harness body 11.

[0056] (Structure of the first path restriction component 40)

[0057] like Figure 4 As 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 in a cylindrical shape that covers the circumferential portion of the outer member 30. The cross-sectional shape of the first path limiting member 40 is generally C-shaped. The first path limiting member 40 covers, for example, an area larger than half the circumference of the outer member 30. 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 portion 11A, and is formed in a shape that extends in a straight line in one direction.

[0058] 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 known manufacturing methods such as extrusion molding or injection molding.

[0059] like Figure 3 As shown, the first path limiting member 40 has a first main body portion 41 that covers a portion of the outer periphery of the outer member 30, and an insertion port 42 that opens in a direction orthogonal to the length direction of the first main body portion 41. The first path limiting member 40 has a first end portion 43 and a second end portion 44 forming the insertion port 42, which are the two circumferential ends of the first main body portion 41.

[0060] like Figure 4 As shown, 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 shape of 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.

[0061] The first end 43 and the second end 44 are disposed opposite 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 through the 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 insertion port 42. Thus, the first path limiting member 40 is formed in a C-shape with the insertion port 42 in a portion of the circumferential direction of the first main body 41.

[0062] The opening width of the insertion port 42, that is, the shortest distance between the first end 43 and the second end 44, is, for example, less than the outer diameter of the outer component 30. Figure 3 As shown, the insertion port 42 extends along the entire length of the first main body portion 41. That is, the insertion port 42 is formed such that it opens in a direction orthogonal to the length direction of the first main body portion 41 and opens at both ends of the length direction of the first main body portion 41.

[0063] By inserting the outer component 30 into the insertion port 42 in a direction orthogonal to the length direction of the first path limiting member 40, the first path limiting member 40 elastically deforms, increasing the opening width of the insertion port 42. When the outer component 30 is inserted into the interior of the first path limiting member 40, the first path limiting member 40 elastically returns to its original shape. Thus, the opening width of the insertion port 42 becomes smaller than the outer diameter of the outer component 30, and therefore the first path limiting member 40 is fitted onto the outer periphery of the outer component 30.

[0064] like Figure 4 As shown, the first end 43 has a tip 43A. The second end 44 has a tip 44A. Tips 43A and 44A form an insertion port 42. Tips 43A and 44A are formed in a curved shape when viewed from the length direction of the first path limiting member 40. That is, the cross-sectional shape of tips 43A and 44A is formed in a curved shape. In this embodiment, the cross-sectional shape of tips 43A and 44A is formed in a semi-circular shape.

[0065] The first path limiting member 40 has, for example, protrusions 45 extending from the inner surfaces of the first end 43 and the second end 44. Each protrusion 45 protrudes toward the outer member 30 inserted into the first path limiting member 40 and can contact the outer surface of the outer member 30. Each protrusion 45, for example, contacts the outer surface of the annular protrusion 31 of the outer member 30. Two protrusions 45, for example, protrude from the inner surfaces of the top ends 43A and 44A. The cross-sectional shape of each protrusion 45 is, for example, formed as a curved shape. In this embodiment, the cross-sectional shape of each protrusion 45 is formed as a semi-circular shape. Each protrusion 45 extends, for example, along the entire length of the first path limiting member 40.

[0066] Each protrusion 45 presses against the outer component 30 from the outside. The outer component 30 is elastically held between the two protrusions 45 and the first main body portion 41. As a result, the connection between the first path limiting member 40 and the outer component 30 becomes secure. Therefore, movement of the first path limiting member 40, which is fitted to the outer periphery of the outer component 30, in the longitudinal direction of the outer component 30 can be suppressed.

[0067] like Figure 3 As shown, the first path limiting member 40 has a connecting portion 47 that connects to the second path limiting member 50. The connecting portion 47 is provided, for example, at the end of the first path limiting member 40 in the longitudinal direction. The connecting portion 47 has a first end face 47A in the longitudinal direction of the first path limiting member 40.

[0068] (Structure of the second path restriction component 50)

[0069] like Figure 2As shown, the second path limiting member 50 is fitted to the outer periphery of the outer member 30 in the bending portion 11B. The second path limiting member 50 is bent along the shape of the bending portion 11B. 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. As a material for the second path limiting member 50, synthetic resins such as polypropylene, polyamide, and polyacetal can be used, for example. The second path limiting member 50 can be manufactured, for example, by a known manufacturing method such as injection molding.

[0070] The second path limiting member 50 has a covering portion 51 that covers a portion of the first path limiting member 40 along its length, and a path limiting portion 70 fitted to the outer periphery of the outer member 30. The second path limiting member 50 is, for example, a single component where the covering portion 51 and the path limiting portion 70 are integrally formed. The covering portion 51 is, for example, provided at one end of the second path limiting member 50 along its length. The covering portion 51 has a second main body portion 52 and a cover portion 56 connected to the second main body portion 52. The path limiting portion 70 has a third main body portion 71. The third main body portion 71 is continuously integrally formed with the second main body portion 52. Here, as... Figure 4 As shown, when the second path limiting member 50 is mounted on the vehicle V, for example, the second main body 52 of the second path limiting member 50 is disposed on the lower side of the cover portion 56 in the vertical direction. When the second path limiting member 50 is mounted on the vehicle V, for example, the second main body 52 of the cover portion 51 is positioned opposite the ground G1.

[0071] (Structure of the covering part 51)

[0072] like Figure 2 As shown, the covering portion 51 is provided overlapping the connecting portion 47 in the radial direction of the outer component 30, for example. That is, in the wire harness 10, one end of the first path limiting member 40 and one end of the second path limiting member 50 are provided overlapping in the longitudinal direction of the wire harness body 11.

[0073] The covering portion 51, for example, surrounds the outer periphery of the connecting portion 47 of the first path limiting member 40. The covering portion 51 is formed, for example, annular, surrounding the outer periphery of the connecting portion 47 and the outer periphery of the outer member 30 in the portion where the connecting portion 47 is assembled. The covering portion 51 extends along the path of the straight portion 11A, for example, and is formed in a shape that extends in a straight line in one direction.

[0074] like Figure 4As shown, the second main body portion 52, for example, covers a portion of the circumferential direction of the outer periphery of the outer member 30. The second main body portion 52, for example, covers a portion of the circumferential direction of the outer periphery of the first path limiting member 40. The second main body portion 52 is formed in a cylindrical shape, with a portion of the circumferential direction of the first path limiting member 40 covering its outer periphery. The second main body portion 52, for example, covers the outer periphery of the first main body portion 41 within the first path limiting member 40. The second main body portion 52, for example, covers the lower vertical side of the first main body portion 41. The second main body portion 52, for example, covers an area larger than half the size of the outer periphery of the first main body portion 41. The cross-sectional shape of the inner surface of the second main body portion 52 is, for example, formed to correspond to the shape of the outer surface of the first main body portion 41. The cross-sectional shape of the inner surface of the second main body portion 52 is, for example, formed to be a curved shape. The cross-sectional shape of the inner surface of the second main body portion 52 is generally U-shaped.

[0075] The second main body portion 52 has a third end portion 53 and a fourth end portion 54, which are the two circumferential ends of the second main body portion 52. The second main body portion 52 has a first receiving opening 55 formed by the third end portion 53 and the fourth end portion 54. The first receiving opening 55 is an opening between the third end portion 53 and the fourth end portion 54. Figure 3 As shown, the first receiving opening 55 opens in a direction orthogonal to the length direction of the second main body 52. ​​The first receiving opening 55 extends along the entire length of the second main body 52. ​​The opening width of the first receiving opening 55, that is, the shortest distance between the third end 53 and the fourth end 54, is, for example, equal to or larger than the outer diameter of the first path limiting member 40. The outer fitting member 30 and the first path limiting member 40 are inserted into the first receiving opening 55 in a direction orthogonal to the length direction of the second path limiting member 50.

[0076] The cover portion 56 is integrally formed with the second main body portion 52, for example. The cross-sectional shape of the inner surface of the cover portion 56 is, for example, formed to correspond to the shape of the outer surface of the outer component 30. The cross-sectional shape of the inner surface of the cover portion 56 is, for example, formed to correspond to the shape of the outer surface of the first path limiting member 40. The cross-sectional shape of the inner surface of the cover portion 56 is, for example, formed into an elliptical arc or an oblong arc. The cover portion 56 is, for example, formed into a generally semi-elliptical cylinder. Here, "oblong" in this specification refers to a shape composed of two parallel lines of approximately equal length and two semicircles.

[0077] The cover 56 covers the first receiving opening 55 of the second main body 52. ​​For example, the cover 56 covers the first receiving opening 55 only in the covering portion 51 in the longitudinal direction of the second path limiting member 50. In other words, the cover 56 is only provided in the covering portion 51 in the second path limiting member 50, and not in the path limiting portion 70.

[0078] The covering portion 51, for example, has a hinge portion 57 that connects the second main body portion 52 and the cover portion 56. The hinge portion 57 connects one circumferential end of the second main body portion 52 (here, the third end portion 53) and one circumferential end of the cover portion 56. One or more (two in this embodiment) locking portions 58 are provided at the other circumferential end of the second main body portion 52 (here, the fourth end portion 54). One or more (two in this embodiment) claw portions 59 are provided at the other circumferential end of the cover portion 56.

[0079] The second main body 52 and the cover 56 can rotate relative to each other about the hinge 57. The cover 56 can rotate about the hinge 57 as an axis. Figure 3 The opening position shown is the same as Figure 2 Rotate between the indicated closed positions. For example... Figure 4 As shown, with the cover 56 in the closed position, the claw 59 hooks onto the locking part 58. Thus, the cover 56 remains in the closed position. In this way, the second main body 52 and the cover 56 are connected to each other. With the second main body 52 and the cover 56 connected, the covering part 51 forms an annular ring that centrally surrounds the outer periphery of the outer component 30 and the connecting part 47. In the closed position, the cover 56 covers the first receiving opening 55 of the second main body 52. ​​For example, in the closed position, the cover 56 covers the insertion opening 42 in the connecting part 47.

[0080] like Figure 3 As shown, the covering portion 51, for example, has a limiting wall 60 that can engage with a first end face 47A of the first path limiting member 40 in the longitudinal direction along the length of the wire harness body 11. The limiting wall 60, for example, protrudes radially inward from the inner surface of the covering portion 51. The limiting wall 60, for example, extends circumferentially along the covering portion 51. The limiting wall 60, for example, extends throughout the entire circumference of the covering portion 51. The limiting wall 60 is provided at one end of the covering portion 51 in the longitudinal direction.

[0081] The limiting wall 60 has, for example, a body-side limiting wall 61 formed on the inner surface of the second body portion 52 and a cover-side limiting wall 62 formed on the inner surface of the cover portion 56. The body-side limiting wall 61 and the cover-side limiting wall 62 are provided at the same position relative to each other, for example, in the length direction of the wire harness body 11.

[0082] like Figure 5As shown, the main body side limiting wall 61 protrudes radially inward from the inner surface of the second main body portion 52. The main body side limiting wall 61 extends, for example, throughout the entire circumference of the second main body portion 52 in the circumferential direction of the covering portion 51. The cross-sectional shape of the inner surface of the main body side limiting wall 61 is formed to be the same as the cross-sectional shape of the inner surface of the second main body portion 52. In this embodiment, the cross-sectional shape of the inner surface of the main body side limiting wall 61 is formed in a U-shape. The cross-sectional shape of the inner surface of the main body side limiting wall 61 is, for example, formed to be one size smaller than the cross-sectional shape of the inner surface of the second main body portion 52.

[0083] The main body side limiting wall 61 has a second receiving opening 63 that opens in a direction orthogonal to the length direction of the second main body 52. ​​The second receiving opening 63 communicates with the first receiving opening 55. The opening width of the second receiving opening 63 is smaller than the opening width of the first receiving opening 55. The opening width of the second receiving opening 63 is, for example, smaller than the outer diameter of the first path limiting member 40.

[0084] like Figure 3 As shown, the main body side limiting wall 61 is provided, for example, at one of the two ends of the second main body portion 52 in the longitudinal direction, at the end connected to the third main body portion 71. The main body side limiting wall 61 extends, for example, along the longitudinal direction of the wire harness body 11. The main body side limiting wall 61 extends, for example, from the end of the second main body portion 52 throughout the entire longitudinal direction of the third main body portion 71. For example, a step is formed at the boundary between the inner surface of the second main body portion 52 and the inner surface of the third main body portion 71 due to the main body side limiting wall 61.

[0085] like Figure 6 As shown, the end face 61A of the main body side limiting wall 61 in the longitudinal direction is opposite to the first main body portion 41 of the first path limiting member 40 in the longitudinal direction of the wire harness main body 11, and can contact the first main body portion 41. The end face 61A of the main body side limiting wall 61 in the longitudinal direction of the wire harness main body 11 is opposite to the first end face 47A of the first path limiting member 40 in the longitudinal direction, and can contact the first end face 47A.

[0086] like Figure 5 As shown, the cover-side limiting wall 62 protrudes radially inward from the inner surface of the cover portion 56. The cover-side limiting wall 62 extends, for example, throughout the entire circumference of the cover portion 56 in the circumferential direction of the covering portion 51. The cross-sectional shape of the inner surface of the cover-side limiting wall 62 is, for example, formed to correspond to the shape of the outer surface of the first path limiting member 40. The cross-sectional shape of the inner surface of the cover-side limiting wall 62 is, for example, formed in a circular arc shape or an elliptical arc shape. In this embodiment, the cross-sectional shape of the inner surface of the cover-side limiting wall 62 is formed in a semi-elliptical arc shape.

[0087] Side limiting wall 62, for example, in wire harness body 11 (see reference) Figure 3It is positioned along the length of the first path limiting member 40 opposite to the first end 43 and the second end 44, and can contact those first ends 43 and the second end 44.

[0088] Thus, the limiting wall 60, which is composed of the main body-side limiting wall 61 and the cover-side limiting wall 62, contacts the first end face 47A of the first path limiting member 40 in the longitudinal direction, thereby limiting the movement of the first path limiting member 40 in the longitudinal direction of the wire harness body 11. For example, the limiting wall 60 limits the movement of the first path limiting member 40 in such a way that the first path limiting member 40 is not inserted into the path limiting part 70.

[0089] like Figure 4 As shown, the covering portion 51 has, for example, a protrusion 65. The protrusion 65 protrudes from the inner surface of the covering portion 51 toward the insertion port 42 of the first path limiting member 40 inserted into the interior of the covering portion 51. The protrusion 65 protrudes in such a manner that it is disposed inside the insertion port 42. The protrusion 65 can contact the first end portion 43 and the second end portion 44 in the circumferential direction of the first path limiting member 40.

[0090] A protrusion 65 is provided, for example, on the inner surface of the cover portion 56. The protrusion 65 protrudes from the inner surface of the cover portion 56 toward the first receiving opening 55. The protrusion 65 is provided, for example, on the inner surface of the cover portion 56 located at the uppermost side in the vertical direction, in the circumferential direction of the covering portion 51. Therefore, with the protrusion 65 positioned inside the insertion opening 42, the insertion opening 42 faces the cover portion 56 side of the covering portion 51. That is, in this embodiment, the insertion opening 42 faces upward in the vertical direction. In other words, in this embodiment, the insertion opening 42 opens upward in the vertical direction.

[0091] like Figure 3 As shown, the protrusion 65 extends, for example, along the length direction of the wire harness body 11. The protrusion 65 extends, for example, along the entire length of the covering portion 51. The protrusion 65 is partially provided, for example, in the circumferential direction of the cover portion 56. The protrusion 65 is, for example, provided in the middle portion of the circumferential direction of the cover portion 56. A portion of the protrusion 65, for example, constitutes a cover-side limiting wall 62. For example, a protrusion 65 provided at one end of the covering portion 51 in the length direction constitutes a cover-side limiting wall 62.

[0092] like Figure 6 As shown, the protrusion 65 has, for example, a protrusion 66 that enters the annular recess 32 of the outer component 30. The protrusion 66 is provided further protruding from the protruding top surface of the protrusion 65. Multiple protrusions 66 are provided in the longitudinal direction of the wire harness body 11. In this embodiment, four protrusions 66 are provided in the longitudinal direction of the wire harness body 11, each entering a different annular recess 32.

[0093] like Figure 3 As shown, the covering portion 51 has a through hole 67 that radially penetrates the covering portion 51 into the outer mounting member 30. The through hole 67 is, for example, provided in the second main body portion 52. Figure 4 As shown, the through hole 67 is provided, for example, in the circumferential direction of the covering portion 51 at a position opposite to the protrusion 65. The through hole 67 is provided, for example, in the radial direction of the covering portion 51 at a position overlapping with the protrusion 65. The through hole 67 is provided, for example, in the lowermost vertical portion of the second main body portion 52 when the wiring harness 10 is mounted on the vehicle V. The through hole 67 opens vertically downwards when the wiring harness 10 is mounted on the vehicle V. The through hole 67 opens towards the ground surface G1.

[0094] like Figure 6 As shown, a through hole 67 is partially provided along the length of the covering portion 51. The covering portion 51 of this embodiment has a through hole 67 along its length. The through hole 67 is provided, for example, in the middle portion along the length of the covering portion 51. The through hole 67 is provided, for example, along the length of the wire harness body 11, away from the second end face 51A of the covering portion 51 by a first distance L1. Here, the second end face 51A is the end face of the second path limiting member 50 along its length, and is also an end face of the covering portion 51. The second end face 51A is provided at the end opposite to the limiting wall 60 of the two ends along the length of the covering portion 51. Furthermore, the first distance L1 can be set, for example, to a distance along the length of the wire harness body 11 corresponding to the minimum insertion amount of the first path limiting member 40 required by the covering portion 51. The minimum insertion amount of the first path limiting member 40 is, for example, the amount of insertion required to make it difficult for the first path limiting member 40 to detach from the covering portion 51, that is, the overlap width between the connecting portion 47 and the covering portion 51 in the wire harness body 11. The minimum insertion amount of the first path limiting member 40 is set, for example, based on the ease with which the first path limiting member 40 moves relative to the covering portion 51 in the length direction of the wire harness body 11. For example, when the first path limiting member 40 can move freely relative to the covering portion 51 in the length direction of the wire harness body 11, the minimum insertion amount of the first path limiting member 40 is set to be larger. In this embodiment, the through hole 67 is provided in the length direction of the covering portion 51 at a position close to the second end face 51A and the limiting wall 60 in the limiting wall 60. That is, in this embodiment, the through hole 67 is provided biased towards the limiting wall 60 in the length direction of the covering portion 51. In this embodiment, the through hole 67 is provided separately from the limiting wall 60 in the length direction of the covering portion 51.

[0095] The planar shape of the through hole 67, viewed from the through-hole direction, can be any shape. For example, the planar shape of the through hole 67 can be circular, semi-circular, polygonal, square, flat, etc. In this embodiment, the planar shape of the through hole 67 is rectangular.

[0096] (Structure of path restriction unit 70)

[0097] like Figure 2 As shown, the third main body 71 of the path limiting portion 70 extends, for example, along the path of the bending portion 11B. That is, the third main body 71 has a bent shape that follows the shape of the bending portion 11B. The third main body 71 covers, for example, a portion of the circumferential direction of the outer member 30. The third main body 71 is formed in a cylindrical shape that covers the outer periphery of the outer member 30 in a portion of its circumferential direction. The third main body 71 covers, for example, an area larger than half the outer periphery of the outer member 30. The cross-sectional shape of the inner surface of the third main body 71 is formed to correspond to the shape of the outer surface of the outer member 30. The cross-sectional shape of the inner surface of the third main body 71 is, for example, formed to be a curved shape. The cross-sectional shape of the inner surface of the third main body 71 is generally U-shaped.

[0098] The third main body 71 has a second receiving opening 63 that opens in a direction orthogonal to the length direction of the third main body 71. The second receiving opening 63 extends along the entire length direction of the third main body 71. The second receiving opening 63 communicates with the first receiving opening 55. The receiving opening formed by the first receiving opening 55 and the second receiving opening 63 extends along the entire length direction of the second path limiting member 50. That is, the receiving opening formed by the first receiving opening 55 and the second receiving opening 63 opens in a direction orthogonal to the length direction of the second path limiting member 50, and opens at both ends of the length direction of the second path limiting member 50.

[0099] The opening width of the second receiving port 63 is, for example, equal to or larger than the outer diameter of the outer component 30. The outer component 30 is inserted into the second receiving port 63 in a direction orthogonal to the length direction of the second path limiting member 50. Furthermore, the first path limiting member 40 is not inserted inside the third main body portion 71.

[0100] like Figure 3 As shown, the path limiting part 70 has a through hole 72 through which the third main body part 71 radially penetrates the outer mounting member 30. Figure 6As shown, the through hole 72 is provided, for example, in the lowermost part of the third main body 71 in the vertical direction when the wiring harness 10 is mounted on the vehicle V. The through hole 72 opens downwards in the vertical direction when the wiring harness 10 is mounted on the vehicle V. The through hole 72 also opens towards the ground G1.

[0101] like Figure 3 As shown, a through hole 72 is partially provided along the length of the path limiting portion 70. In this embodiment, the path limiting portion 70 has a through hole 72 along its length. The through hole 72 is, for example, provided in the middle portion along the length of the path limiting portion 70. The through hole 72 and the through hole 67 are arranged along the length of the wire harness body 11, for example. The through hole 72 is, for example, offset towards the second body portion 52 along the length of the path limiting portion 70. Figure 6 As shown, the through hole 72 is provided, for example, in the longitudinal direction of the second path limiting member 50 on the side opposite to the through hole 67, at the end face 61A of the main body side limiting wall 61. For example, the through hole 72 is provided in the longitudinal direction of the second path limiting member 50 at the same distance from the end face 61A of the main body side limiting wall 61 as the through hole 67.

[0102] The planar shape of the through hole 72, viewed from the through-hole direction, can be any shape. For example, the planar shape of the through hole 72 can be circular, semi-circular, polygonal, square, flat, etc. In this embodiment, the planar shape of the through hole 72 is rectangular.

[0103] (Structure of fixed components 81 and 82)

[0104] like Figure 2 As shown, the wire harness 10 includes, for example, a fixing member 81 that secures the first path limiting member 40 to the outer periphery of the outer component 30. The wire harness 10 also includes, for example, a fixing member 82 that secures the second path limiting member 50 to the outer periphery of the outer component 30. The fixing members 81 and 82 can be, for example, resin or metal strapping, fastening rings, or adhesive tape. In this embodiment, the fixing members 81 and 82 are adhesive tape.

[0105] The fixing member 81 is formed, for example, by fixing the end of the first path limiting member 40 located on the side opposite to the connecting portion 47 in the longitudinal direction to the outer surface of the outer member 30. The fixing member 81 is wound from the outer surface of the end of the first path limiting member 40 in the longitudinal direction across the outer surface of the outer member 30. This suppresses movement of the first path limiting member 40 relative to the outer member 30 in both the longitudinal and circumferential directions of the wire harness body 11. The fixing member 82 is formed, for example, by fixing the end of the second path limiting member 50 located on the side opposite to the covering portion 51 in the longitudinal direction to the outer surface of the outer member 30. The fixing member 82 is wound from the outer surface of the end of the second path limiting member 50 in the longitudinal direction across the outer surface of the outer member 30. This suppresses movement of the second path limiting member 50 relative to the outer member 30 in both the longitudinal and circumferential directions of the wire harness body 11.

[0106] Next, the function of this embodiment will be explained.

[0107] Along the length of the wire harness body 11, the connecting portion 47 of the first path limiting member 40 and the covering portion 51 of the second path limiting member 50 are arranged overlappingly. At this time, the covering portion 51, which covers the outer periphery of the connecting portion 47, is provided with a through hole 67 that radially penetrates the covering portion 51 into the outer member 30. Therefore, even if a liquid, such as water, is immersed between the outer surface of the connecting portion 47 and the inner surface of the covering portion 51, the liquid can be discharged through the through hole 67 to the outside of the second path limiting member 50.

[0108] Next, the effects of this embodiment will be explained.

[0109] (1) A through hole 67 is provided in the covering portion 51 that covers the outer periphery of the connecting portion 47, extending radially through the covering portion 51 into the outer mounting member 30. According to this structure, because it achieves the aforementioned effect, liquid retention between the outer surface of the connecting portion 47 and the inner surface of the covering portion 51 can be suppressed. Therefore, it is possible to appropriately suppress the second path limiting member 50 from the first path limiting member 40 due to the weight of the liquid retained between the outer surface of the connecting portion 47 and the inner surface of the covering portion 51. As a result, the connection reliability between the first path limiting member 40 and the second path limiting member 50 can be improved.

[0110] (2) The insertion port 42 of the first path limiting member 40 opens in a direction orthogonal to the length direction of the first path limiting member 40 and extends along the entire length of the first path limiting member 40. Therefore, after end processing such as assembling connectors C1 and C2 to the ends of the wire member 20 in the length direction, the first path limiting member 40 can be assembled onto the outer member 30 through the insertion port 42. This allows for the subsequent installation of the first path limiting member 40, thus improving the assembly workability of the wire harness 10.

[0111] (3) A through hole 67 is provided in the covering portion 51 that covers the outer periphery of the first main body portion 41. Here, liquid is more likely to be retained between the outer surface of the first main body portion 41 and the inner surface of the covering portion 51 than between the insertion port 42 and the inner surface of the covering portion 51. Therefore, by providing the through hole 67 in the part where liquid is more likely to be retained, liquid can be properly discharged to the outside of the second path limiting member 50 through the through hole 67. As a result, the detachment of the second path limiting member 50 from the first path limiting member 40 can be appropriately suppressed, and the connection reliability between the first path limiting member 40 and the second path limiting member 50 can be improved.

[0112] (4) The through hole 67 opens downward in the vertical direction when the wire harness 10 is mounted on the vehicle V. According to this structure, because the through hole 67 opens downward in the vertical direction, liquid that has entered between the outer surface of the connecting part 47 and the inner surface of the covering part 51 can be efficiently discharged to the outside of the second path limiting member 50 through the through hole 67.

[0113] (5) In the longitudinal direction of the wire harness body 11, the first end face 47A of the first path limiting member 40 engages with the limiting wall 60 of the second path limiting member 50. This suppresses relative movement of the first path limiting member 40 relative to the second path limiting member 50 in the longitudinal direction of the wire harness body 11. Therefore, misalignment of the first path limiting member 40 relative to the second path limiting member 50 in the longitudinal direction of the wire harness body 11 is suppressed. As a result, the positional accuracy of the first path limiting member 40 relative to the second path limiting member 50 is improved. In this embodiment, the second path limiting member 50 is fixed to the outer component 30 of the wire harness body 11 by the fixing member 82. Therefore, movement of the second path limiting member 50 relative to the wire harness body 11 in the longitudinal direction of the wire harness body 11 is suppressed. Therefore, by improving the positional accuracy of the first path limiting member 40 relative to the second path limiting member 50, the positional accuracy of the first path limiting member 40 relative to the wire harness body 11 is improved. As a result, the first path limiting member 40 can be appropriately positioned at the desired location on the wire harness body 11, which is the straight section 11A, and the path of the straight section 11A can be appropriately limited by the first path limiting member 40. In other words, the deviation of the first path limiting member 40 from the straight section 11A relative to the wire harness body 11 can be appropriately suppressed.

[0114] (6) When the first path limiting member 40 is assembled to the second path limiting member 50, the first end face 47A of the first path limiting member 40 in the length direction is engaged with the limiting wall 60, so that the first path limiting member 40 can be easily positioned relative to the second path limiting member 50 in the length direction of the wire harness body 11.

[0115] (7) The through hole 67 is provided at a first distance L1 from the second end face 51A in the longitudinal direction of the covering portion 51. The first distance L1 corresponds to the minimum insertion amount of the first path limiting member 40 required relative to the covering portion 51. Therefore, the through hole 67 can be used as a hole for confirming the insertion amount of the first path limiting member 40 relative to the covering portion 51, specifically the insertion amount of the first path limiting member 40 in the longitudinal direction of the wire harness body 11. That is, even from the outside of the second path limiting member 50, the insertion amount of the first path limiting member 40 relative to the covering portion 51 can be confirmed through the through hole 67. For example, when it can be confirmed through the through hole 67 that the first path limiting member 40 is inserted into the through hole 67, it can be confirmed that the first path limiting member 40 is inserted into the covering portion 51 by a predetermined minimum insertion amount or more.

[0116] (8) The through hole 67 is provided biased toward the limiting wall 60 in the longitudinal direction of the covering portion 51. According to this structure, for example, the through hole 67 is provided near the limiting wall 60, which is used as a positioning member of the first path limiting member 40 in the longitudinal direction of the wire harness body 11. Therefore, for example, it can be confirmed through the through hole 67 whether the first path limiting member 40 in the longitudinal direction of the wire harness body 11 is inserted near the limiting wall 60.

[0117] (9) The second path limiting member 50 has a through hole 72 through which the path limiting part 70 radially passes through the outer member 30. The through hole 72 is arranged along the length direction of the second path limiting member 50 and the through hole 67. Therefore, based on the position of the first path limiting member 40 that can be confirmed through the through hole 67 and the through hole 72, the insertion amount of the first path limiting member 40 relative to the second path limiting member 50 can be appropriately determined.

[0118] (10) The covering portion 51 is formed as an annulus that centrally surrounds the connecting portion 47 and the outer component 30. The covering portion 51 has a second main body portion 52 that covers a portion of the outer periphery of the first main body portion 41, and a cover portion 56 connected to the second main body portion 52. According to this structure, although the covering portion 51 is set as an annulus that surrounds the connecting portion 47 and the outer component 30, it is divided into a second main body portion 52 and a cover portion 56 by the covering portion 51, so that the second path limiting member 50 including the covering portion 51 can be subsequently installed on the first path limiting member 40 and the outer component 30. As a result, the assembly workability of the wire harness 10 is further improved.

[0119] (11) The covering portion 51 has a protrusion 65 that can contact at least one of the first end portion 43 and the second end portion 44 forming the insertion port 42 in the circumferential direction of the first path limiting member 40. Therefore, in the circumferential direction of the first path limiting member 40, the protrusion 65 engages with the first end portion 43 or the second end portion 44. Through these engagements, relative movement of the first path limiting member 40 relative to the covering portion 51 can be suppressed in the circumferential direction of the first path limiting member 40. That is, by the mutual engagement of the protrusion 65 with the first end portion 43 or the second end portion 44, circumferential rotation of the first path limiting member 40 relative to the covering portion 51 can be suppressed. Therefore, misalignment of the first path limiting member 40 relative to the covering portion 51 can be suppressed in the circumferential direction of the first path limiting member 40, and the positional accuracy of the first path limiting member 40 relative to the covering portion 51 can be improved.

[0120] (12) The protrusion 65 has a protrusion 66 that enters the annular recess 32 of the outer component 30, so that the movement of the outer component 30 relative to the second path limiting member 50 can be suppressed in the length direction of the outer component 30.

[0121] (13) The first path limiting member 40 has a protrusion 45 that protrudes from the inner surface of at least one of the first end 43 and the second end 44 and can contact the outer surface of the outer member 30. Through this protrusion 45, for example, the outer member 30 can be pressed from the outside of the outer member 30. Therefore, the first path limiting member 40 can be appropriately prevented from disengaging from the outer member 30 through the insertion port 42.

[0122] (14) The path of the straight section 11A is restricted by the first path restricting member 40, and the path of the bent section 11B is restricted by the second path restricting member 50. As a result, the paths of the straight section 11A and the bent section 11B can be prevented from deviating from the desired paths.

[0123] (Other implementation methods)

[0124] The above-described embodiments can be implemented with the following modifications. The above-described embodiments and the following modifications can be combined with each other within the scope of technical inconsistency.

[0125] • The location of the through hole 67 in the above embodiments is not particularly limited. For example, the location of the through hole 67 in the circumferential direction of the covering portion 51 can be appropriately changed to any location. For example, the through hole 67 can also be provided in the cover portion 56 in the covering portion 51. In this case, it is preferable that, when the wiring harness 10 is mounted on the vehicle V, the cover portion 56 is provided on the lower side in the vertical direction than the second main body portion 52.

[0126] • In addition, the position of the through hole 67 in the length direction of the covering part 51 can be appropriately changed to any position.

[0127] For example Figure 7 As shown, the through hole 67 can also be provided adjacent to the limiting wall 60 in the longitudinal direction of the covering portion 51. Alternatively, the through hole 67 can be provided adjacent to the main body-side limiting wall 61 in the longitudinal direction of the covering portion 51. For example, a portion of the inner surface of the through hole 67 and the end face 61A of the main body-side limiting wall 61 can be formed in a continuously extending manner.

[0128] • As in the embodiment described above, when the end of the first path limiting member 40 in the longitudinal direction is fixed to the outer surface of the outer member 30 by the fixing member 81, the movement of the first path limiting member 40 in the longitudinal direction of the wire harness body 11 is restricted. Therefore, the through hole 67 can also be provided in the longitudinal direction of the covering portion 51 at a position biased towards the second end face 51A.

[0129] • If the through hole 67 is not used as a hole for confirming the insertion amount of the first path limiting member 40 relative to the covering portion 51, it is not necessary to provide the through hole 67 at a position away from the first distance L1 from the second end face 51A of the covering portion 51. In this case, for example, the through hole 67 may be provided at a position offset towards the second end face 51A in the longitudinal direction of the covering portion 51. For example, the through hole 67 may be provided by cutting out the second end face 51A.

[0130] In the above embodiment, a through hole 67 is provided in the covering portion 51, but it is not limited to this, and multiple through holes 67 may also be provided in the covering portion 51.

[0131] For example Figure 8 As shown, two through holes 67 can also be provided in the covering portion 51. Both through holes 67 are provided in the second main body portion 52. The two through holes 67 are arranged, for example, along the length direction of the covering portion 51.

[0132] According to this structure, a plurality of through holes 67 are arranged along the length direction of the covering portion 51. Therefore, the position of the first path limiting member 40 can be confirmed through the plurality of through holes 67, thereby properly confirming where the first path limiting member 40 is inserted relative to the second path limiting member 50.

[0133] In the above embodiment, second path limiting members 50 may also be provided on both sides of the first path limiting member 40 in the longitudinal direction. In this case, for example, between one second path limiting member 50 and the other, the first path limiting member 40 may easily move along the longitudinal direction of the wire harness body 11. In this case, for example, the minimum insertion amount of the first path limiting member 40 relative to the covering portion 51 may be set to be relatively large.

[0134] • The structure of the second path limiting member 50 in the above embodiment can be appropriately modified. For example, as long as the second path limiting member 50 has a covering portion 51 that covers the connecting portion 47 and is provided with a through hole 67, other structures are not particularly limited.

[0135] • The through hole 72 of the path limiting part 70 can also be omitted.

[0136] • The protrusion 66 of the cover 56 can also be omitted.

[0137] • The protrusion 65 of the cover 56 can also be omitted.

[0138] • At least one of the main body side limiting wall 61 and the cover side limiting wall 62 may be omitted.

[0139] In the covering portion 51 of the above embodiment, the second main body portion 52 and the cover portion 56 are formed as one piece, but this is not a limitation; the second main body portion 52 and the cover portion 56 can also be separated. That is, the second main body portion 52 and the cover portion 56 can also be separate parts.

[0140] • The cover portion 56 of the covering portion 51 can also be omitted.

[0141] • The bending shape in the path restriction section 70 can be appropriately changed.

[0142] • The cross-sectional shape of the inner surface of the second main body 52 and the third main body 71 is not limited to a U-shape, but can be changed to a circular arc shape, an elliptical arc shape, etc.

[0143] • It is also possible to provide a cover that is connected to the third main body 71.

[0144] The second path limiting member 50 in the above embodiment is formed to limit the path of the bent portion 11B of the wire harness body 11, but it is not limited thereto. For example, the second path limiting member 50 may be changed to a shape that limits the path of the straight portion 11A of the wire harness body 11. In this case, for example, the bent shape in the path limiting portion 70 of the second path limiting member 50 is changed to a shape that extends in a straight line.

[0145] In the above embodiment, the assembly member having the covering portion 51 is specifically embodied as the second path limiting member 50, but it is not limited thereto. For example, the assembly member may also be embodied as a structure having only the covering portion 51.

[0146] • The structure of the first path limiting member 40 in the above embodiment can be appropriately modified. For example, as long as the first path limiting member 40 has a structure such as having an insertion port 42 and being able to be assembled to the outer periphery of the outer member 30, other structures are not particularly limited.

[0147] Alternatively, each protrusion 45 in the above embodiment can be positioned in the circumferential direction of the first path limiting member 40 at a position further away from the insertion port 42 than the top ends 43A and 44A.

[0148] • Alternatively, each protrusion 45 may be provided locally along the length of the first path limiting member 40.

[0149] • Alternatively, at least one of the two protrusions 45 can be omitted.

[0150] • A second protrusion may also be provided in the first path limiting member 40. The second protrusion protrudes from the inner surface of the circumferential middle portion of the first main body portion 41 and can contact the outer surface of the outer component 30. According to this structure, both the protrusion 45 and the second protrusion can contact the outer surface of the outer component 30. Therefore, the swaying of the first path limiting member 40 can be suppressed.

[0151] • In the first path limiting member 40, a groove extending along the length direction may also be provided on the outer surface of the first main body 41. According to this structure, the first main body 41 can be easily deformed outwards from the groove, thereby easily enlarging the insertion opening 42. As a result, this contributes to improving the assemblability of the first path limiting member 40.

[0152] • The radial thickness of the first main body 41 can also be configured to change in the circumferential direction.

[0153] • The cross-sectional shape of the first main body 41 is not limited to a circular arc shape; for example, it can be changed to an elliptical arc shape, a U-shaped shape, etc.

[0154] In the above embodiment, the first path limiting member 40 and the second path limiting member 50 are harder than the outer member 30, but this is not the case; they may also be of the same or lower hardness as the outer member 30. That is, the first path limiting member 40 and the second path limiting member 50 may not be harder than the outer member 30 as long as they function in a way that makes the wire harness body 11 less prone to bending than the wire harness body 11 without the first path limiting member 40 and the second path limiting member 50.

[0155] • Alternatively, at least one of the fixing members 81 and 82 in the above embodiments can be omitted.

[0156] • The external component 30 in the above embodiment may also be a component in which a metal layer containing a metal material is provided on the outer surface of a resin corrugated pipe.

[0157] • The external component 30 of the above embodiments is not limited to a bellows, and may also be an external component without the annular protrusion 31 and the annular recess 32.

[0158] • The outer component 30 in the above embodiment may also be a component having a slit extending in the length direction of the outer component 30.

[0159] • In the above embodiment, the wire 21 is set as a high-voltage wire, but it is not limited to this. For example, the wire 21 can also be set as a low-voltage wire.

[0160] In the wire component 20 of the above embodiment, the electromagnetic shielding component is specifically embodied as a braided component 25, but it is not limited thereto. For example, the electromagnetic shielding component in the wire component 20 may also be embodied as a metal foil.

[0161] • The braided component 25 in the wire component 20 of the above embodiment can also be omitted.

[0162] In the above embodiment, two wires 21 constituting the wire member 20 are provided, but it is not limited to this. The number of wires 21 can be one or more.

[0163] • 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 modified according to the vehicle structure.

[0164] In the above embodiment, the multiple vehicle-mounted 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 thereto. The multiple vehicle-mounted devices electrically connected to the wiring harness 10 are not particularly limited as long as they are electrical devices mounted on the vehicle V.

[0165] The embodiments disclosed herein should be considered illustrative in all respects and not restrictive. The scope of the invention is not as described above, but is shown by the claims and includes all modifications within the meaning and scope of the claims.
