[0026] [Description of embodiments of this disclosure]

[0027] [Description of embodiments of this disclosure]

[0028] First, the implementation methods of this disclosure are listed and explained.

[0029] The wire harness disclosed herein comprises: 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 a movement limiting member fitted to the outer periphery of the outer member to limit relative movement of the path limiting member relative to the outer member in the length direction of the outer member. The outer member has a corrugated shape in which annular protrusions and annular recesses are alternately connected in the length direction of the outer member. The path limiting member has an insertion port that opens in a direction orthogonal to the length direction of the path limiting member and extends along the entire length direction of the path limiting member. The movement limiting member has a first engaging portion that engages with the annular recess and a second engaging portion that engages with an end face in the length direction of the path limiting member.

[0030] According to this structure, a movement limiting member is provided to restrict the relative movement of the path limiting member relative to the outer component in the length direction of the outer component. The movement limiting member has a first engaging portion that engages with the annular recess, and a second engaging portion that engages with the end face of the path limiting member in the length direction. Accordingly, by engaging the first engaging portion with the annular recess, the first engaging portion can engage with the inner surface of the annular recess or the side surface of the annular protrusion in the length direction of the outer component. Therefore, relative movement of the movement limiting member relative to the outer component can be suppressed in the length direction of the outer component. Thus, misalignment of the movement limiting member relative to the outer component can be suppressed in the length direction of the outer component. Furthermore, in the length direction of the outer component, the end face of the path limiting member engages with the second engaging portion. Therefore, relative movement of the path limiting member relative to the outer component and the movement limiting member can be suppressed in the length direction of the outer component. Thus, misalignment of the path limiting member relative to the outer component can be suppressed in the length direction of the outer component. As a result, the positional accuracy of the path limiting component relative to the outer component and the positional accuracy of the path limiting component relative to the main body of the wiring harness can be improved. Therefore, the path limiting component can be used to appropriately limit the path at the desired position of the main body of the wiring harness.

[0031] Preferably, the movement limiting member is a strapping band, having: a band portion extending in a first direction along the circumference of the outer component and having a thickness in a second direction along the radial direction of the outer component, and a width in a third direction along the length of the outer component; and a locking portion integral with the band portion and disposed at a first end of the band portion in the first direction, the band portion having a first end face facing the outer surface of the outer component in the second direction, and a second end face disposed in the second direction on the side opposite to the first end face, the first engaging portion being a protrusion projecting from the first end face toward the outer component. According to this structure, the relative movement of the path limiting member relative to the outer component can be limited in the length direction of the outer component by means of the strapping band having the band portion and the locking portion. In the strapping band, the band portion can be easily wrapped around the outer periphery of the outer component, thus improving the assembly workability of the wire harness. Furthermore, by engaging the protrusion and the annular recess on the first end face of the belt, the protrusion and the outer component are mutually engaged in the longitudinal direction of the outer component. This appropriately suppresses the relative movement of the movement restriction member relative to the outer component in the longitudinal direction of the outer component.

[0032] Preferably, in the third direction, the size of the strip portion is larger than the size of the protrusion, and the strip portion is formed to a size that cannot be engaged with the annular recess. According to this structure, the strip portion is formed to a size that cannot be engaged with the annular recess, thus allowing the first end face of the strip portion to contact the outer surface of the outer component, specifically the outer surface of the annular protrusion. This facilitates the positioning of the radial movement restriction member of the outer component and allows the strip portion to be stably wound around the outer surface of the outer component.

[0033] Preferably, the belt portion has a third end face facing the end face of the path limiting member in the third direction along its length, and a fourth end face disposed in the third direction on the side opposite to the third end face, and the second engaging portion is the third end face. According to this structure, in the length direction of the outer component, the end face of the path limiting member engages with the third end face of the belt portion. Therefore, relative movement of the path limiting member relative to the outer component and the movement limiting member can be suppressed in the length direction of the outer component. Thus, misalignment of the path limiting member relative to the outer component can be suppressed in the length direction of the outer component.

[0034] Preferably, the movement limiting member has a protrusion that protrudes outward from the third end of the belt portion in the third direction, and the protrusion can contact the outer surface of the path limiting member. According to this structure, the movement limiting member has a protrusion that protrudes outward from the third end of the belt portion and can contact the outer surface of the path limiting member. This protrusion allows the path limiting member to be covered from the outside. Therefore, movement of the path limiting member across the movement limiting member in the longitudinal direction of the outer component can be appropriately suppressed. Thus, misalignment of the path limiting member relative to the outer component in the longitudinal direction of the outer component can be appropriately suppressed.

[0035] Preferably, the protrusion has: a base end portion extending along the third direction and being one end portion of the third direction, connected to the belt portion; and a top end portion disposed on the side opposite to the base end portion in the third direction, the protrusion being elastically deformable such that the top end portion deviates from the base end portion in the second direction. According to this structure, the top end portion of the protrusion can elastically deform in a manner that deviates from the base end portion in the second direction. Therefore, even in cases where, for example, the size of the path limiting member changes, the top end portion of the protrusion can be properly contacted with the outer surface of the path limiting member by changing the amount of elastic deformation of the protrusion. In other words, by changing the amount of elastic deformation of the protrusion, a single movement limiting member can be used for multiple path limiting members of different sizes.

[0036] Preferably, the movement limiting member has a plurality of protrusions, which are spaced apart from each other in the first direction of the belt portion. According to this structure, the outer surface of the path limiting member is covered by the plurality of protrusions spaced apart from each other in the first direction of the belt portion. Therefore, the outer surface of the path limiting member can be covered by the plurality of protrusions over a wide circumferential range of the outer component. This more appropriately suppresses, for example, movement of the path limiting member across the movement limiting member in the longitudinal direction of the outer component. Therefore, misalignment of the path limiting member relative to the outer component can be more appropriately suppressed in the longitudinal direction of the outer component.

[0037] Preferably, the tip portion of the protrusion has a large width portion whose dimension along the first direction is larger than the dimension along the first direction of the base portion of the protrusion, and the large width portion can contact the outer surface of the path limiting member. According to this structure, the outer surface of the path limiting member is covered by the large width portion. Therefore, the outer surface of the path limiting member can be covered by the large width portion over a wide circumferential range of the outer component. This more appropriately suppresses, for example, movement of the path limiting member across the movement limiting member in the longitudinal direction of the outer component. Therefore, misalignment of the path limiting member relative to the outer component can be more appropriately suppressed in the longitudinal direction of the outer component.

[0038] Preferably, when the protrusion is designated as the first protrusion, the movement limiting member has a second protrusion that protrudes outward from the fourth end face of the belt portion in the third direction, extending in the third direction in the opposite direction to the first protrusion, and is capable of contacting the outer surface of the path limiting member. According to this structure, a first protrusion and a second protrusion protruding to both sides of the belt portion in the third direction are provided. Therefore, when the movement limiting member is assembled to the outer periphery of the outer component, the constraint of the belt portion's orientation in the third direction can be eliminated. Even in cases where, for example, the movement limiting member is assembled to the outer surface of the outer component with the fourth end face of the belt portion facing the end face of the path limiting member in the longitudinal direction, the second protrusion can still contact the outer surface of the path limiting member. This improves the assembly workability of the movement limiting member, and consequently improves the assembly workability of the wire harness.

[0039] Preferably, the strap portion has a first end portion connected to the locking portion and a second end portion disposed on the opposite side of the first end portion in the first direction. The second end portion has a plurality of third engaging portions disposed at intervals from each other in the first direction of the strap portion. The locking portion has: an insertion hole into which the second end portion of the strap portion can be inserted; and a fourth engaging portion disposed on the inner surface of the insertion hole and capable of engaging with the third engaging portions. The first engaging portion is not disposed on the second end portion. According to this structure, by inserting the second end portion of the strap portion into the insertion hole of the locking portion and engaging the fourth engaging portion of the locking portion with one of the plurality of third engaging portions, the strap portion can be locked to the locking portion. At this time, by changing the insertion degree of the strap portion relative to the locking portion, the size of the inner circumference of the movement limiting member can be made consistent with the outer size of the outer component. In other words, by adjusting the insertion degree of the strap portion relative to the locking portion, a single movement limiting member can be used for various outer components with different outer sizes. Furthermore, the first engaging portion is not provided at the second end of the belt portion where the third engaging portion is located. Therefore, the engagement of the third and fourth engaging portions can be prevented from being obstructed by the first engaging portion.

Moreover, the invention is not limited to these examples, but as indicated by the claims, it is intended to include all modifications within the meaning and scope equivalent to the claims.

[0042] (Overall structure of wire harness 10)

[0043] 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 in the longitudinal direction passes under the floor of the vehicle V or outside the passenger compartment.

[0044] 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 (AC) from the DC power 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.

[0045] 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.

[0046] like Figure 2 and Figure 3 As shown, the wire harness 10 has a path limiting member 40 and a path limiting member 50 mounted on the outer periphery of the outer component 30. Each path limiting member 40, 50 limits the routing path of the wire harness body 11. The wire harness 10 also has a movement limiting member 70 that limits the movement of the path limiting member 40. Furthermore, in... Figure 1 The diagrams of path restriction components 40 and 50 and movement restriction component 70 are omitted.

[0047] (Structure of electrical component 20)

[0048] 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.

[0049] 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.

[0050] 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 cylindrical conductor with a hollow internal structure can be used. As the core wire 22, stranded wires, cylindrical conductors, and cylindrical conductors can also be used in combination. As the material of the core wire 22, for example, copper-based metals, aluminum-based metals, etc., can be used.

[0051] 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.

[0052] The cross-sectional shape of each wire 21, which is the shape of the cross section formed by cutting the wire 21 with 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.

[0053] 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.

[0054] (Structure of external component 30)

[0055] 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.

[0056] The external component 30 is flexible and can be easily bent. Examples of flexible external components 30 include, for example, a resin corrugated pipe and a rubber waterproof cover.

[0057] like Figure 5 As shown, the outer casing 30 of this embodiment is a resin corrugated tube with a corrugated shape whose diameter repeatedly increases and decreases along the length of the outer casing 30. That is, the outer casing 30 of this embodiment has a corrugated structure in which annular protrusions 31 and annular recesses 32 are alternately and continuously provided along the length of the outer casing 30. Each of the annular protrusions 31 and annular recesses 32 is, for example, formed as an annulus that wraps around the circumference of the outer casing 30. As the material for the outer casing 30, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used, for example. Furthermore, in Figures 1-3 In order to simplify the accompanying drawings, the external component 30 is shown in a simplified manner.

[0058] like Figure 5As shown, the outer casing 30 of this embodiment is a resin corrugated tube with a corrugated shape whose diameter repeatedly increases and decreases along the length of the outer casing 30. That is, the outer casing 30 of this embodiment has a corrugated structure in which annular protrusions 31 and annular recesses 32 are alternately and continuously provided along the length of the outer casing 30. Each of the annular protrusions 31 and annular recesses 32 is, for example, formed as an annulus that wraps around the circumference of the outer casing 30. As the material for the outer casing 30, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used, for example. Furthermore, in Figures 1-3 In order to simplify the accompanying drawings, the external component 30 is shown in a simplified manner.

[0059] (Structure of path-restricting components 40 and 50)

[0060] like Figure 2 and Figure 3 As shown, path limiting members 40 and 50 each hold the outer member 30. Each of the path limiting members 40 and 50 is, for example, more rigid than the outer member 30. Each of the path limiting members 40 and 50 has a rigidity that makes it less prone to bending in a direction orthogonal to the length direction of the wire harness body 11 compared to the outer member 30. Thus, each of the path limiting members 40 and 50 restricts the path of the wire harness body 11. For example, each of the path limiting members 40 and 50 assists in restricting 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 deflections. Each of the path limiting members 40 and 50 is locally provided along the length direction of the wire harness body 11. Furthermore, one or more of each of the path limiting members 40 and 50 are provided according to the path of the wire harness body 11.

[0061] Path limiting member 40 is, for example, fitted to the outer periphery of outer member 30 in straight section 11A, where straight section 11A is a straight portion forming a straight line in the path of wire harness body 11. Path limiting member 40 limits the path of wire harness body 11 in straight section 11A. Here, straight section 11A is a portion where the path of wire harness body 11 extends straight in one direction. Path limiting member 50 is, for example, fitted to the outer periphery of outer member 30 in bending section 11B, where bending section 11B is a bent portion in the path of wire harness body 11. Path limiting member 50 limits the path of wire harness body 11 in bending section 11B. Here, bending section 11B is a portion where the path of wire harness body 11 is bent in a two-dimensional or three-dimensional manner.

[0062] (Structure of path restriction component 40)

[0063] like Figure 4As shown, the path limiting member 40 covers a portion of the circumferential periphery of the outer member 30. The path limiting member 40 is formed in a cylindrical shape that covers the circumferential periphery of the outer member 30. For example, the path limiting member 40 covers an area larger than half the circumference of the outer member 30. That is, the path limiting member 40 covers an area larger than half the total circumference of the outer member 30. The cross-sectional shape of the path limiting member 40 is generally C-shaped. For example, the cross-sectional shape of the path limiting member 40 is the same along its entire length. Figure 3 As shown, the path limiting member 40 extends along the path of the straight portion 11A and is formed into a shape that extends in a straight line in one direction.

[0064] The path limiting member 40 is made of, for example, metal or resin. In this embodiment, the 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 path limiting member 40. The path limiting member 40 can be manufactured, for example, by known manufacturing methods such as extrusion molding or injection molding.

[0065] The path limiting member 40 has an insertion port 40X that opens in a direction orthogonal to the length direction of the path limiting member 40. The path limiting member 40 has end portions 41 and 42 forming the insertion port 40X, which are the two circumferential ends of the path limiting member 40. The path limiting member 40 has a connecting portion 43 that connects the end portions 41 and 42. In other words, the path limiting member 40 has: a connecting portion 43 that covers a portion of the circumferential direction of the outer component 30; end portions 41 and 42 provided at the two ends of the connecting portion 43; and an insertion port 40X formed through the end portions 41 and 42.

[0066] like Figure 4 As shown, the connecting portion 43 constitutes the main part of the path limiting member 40. The radial thickness of the connecting portion 43 is the same as that of the path limiting member 40 in the circumferential direction. The cross-sectional shape of the connecting portion 43 is formed, for example, along the shape of the outer surface of the outer member 30. The cross-sectional shapes of the ends 41, 42 and the connecting portion 43 are formed, for example, arcuate.

[0067] End portions 41 and 42 are disposed on opposite sides of each other in the circumferential direction of the path limiting member 40. End portions 41 and 42 are separated from each other by an insertion opening 40X in the circumferential direction of the path limiting member 40. In other words, the gap between end portions 41 and 42 in the circumferential direction of the path limiting member 40 forms the insertion opening 40X. Thus, the path limiting member 40 is formed in a C-shape with the insertion opening 40X in a portion of its circumferential direction.

[0068] End portion 41 has a tip 41A. End portion 42 has a tip 42A. Tips 41A and 42A form an insertion port 40X. In other words, tips 41A and 42A constitute the inner surface of the insertion port 40X. Tips 41A and 42A are formed in a curved shape, for example, when viewed from the length direction of the path limiting member 40. That is, the cross-sectional shape of tips 41A and 42A is formed in a curved shape. In this embodiment, the cross-sectional shape of tips 41A and 42A is formed in a semi-circular shape.

[0069] The path limiting member 40 has, for example, protrusions 45 extending from the inner surfaces of its ends 41 and 42. Each protrusion 45 protrudes toward the outer member 30 inserted into the 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. Each protrusion 45, for example, protrudes from the inner surfaces of its top ends 41A and 42A. The cross-sectional shape of each protrusion 45 is, for example, curved. In this embodiment, the cross-sectional shape of each protrusion 45 is semi-circular. Each protrusion 45 extends along the length of the path limiting member 40. Each protrusion 45 extends, for example, along the entire length of the path limiting member 40.

[0070] Each protrusion 45 presses against the outer component 30 from the outside. The outer component 30 is elastically held, for example, by the two protrusions 45 and the connecting portion 43. As a result, the connection between the path limiting member 40 and the outer component 30 becomes secure. Therefore, the path limiting member 40, which is fitted to the outer periphery of the outer component 30, can inhibit the movement of the outer component 30 in the longitudinal direction.

[0071] The opening width of the insertion port 40X, that is, the shortest distance between end 41 and end 42, is, for example, less than the outer diameter of the outer component 30. Figure 3 As shown, the insertion port 40X extends along the length direction of the path limiting member 40. The insertion port 40X extends along the entire length direction of the path limiting member 40. That is, the insertion port 40X is formed such that it opens in a direction orthogonal to the length direction of the path limiting member 40 and opens at both ends of the length direction of the path limiting member 40.

[0072] By inserting the outer component 30 into the insertion port 40X in a direction orthogonal to the length direction of the path limiting component 40, the path limiting component 40 elastically deforms, increasing the opening width of the insertion port 40X. When the outer component 30 is inserted into the path limiting component 40, the path limiting component 40 elastically returns to its original shape. Thus, the opening width of the insertion port 40X becomes smaller than the outer diameter of the outer component 30, and therefore the path limiting component 40 is fitted onto the outer periphery of the outer component 30.

[0073] The path limiting member 40 has an end 47 and an end 48, which are the two ends of the path limiting member 40 in the longitudinal direction. The end 48 has an end face 48A in the longitudinal direction of the path limiting member 40.

[0075] like Figure 2 and Figure 3 As shown, the path limiting member 50 is bent along the shape of the bending portion 11B. The path limiting member 50 is made of metal or resin, for example. In this embodiment, the 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 path limiting member 50. The path limiting member 50 is manufactured, for example, by injection molding.

[0076] The path limiting member 50 has a main body 51 and a covering part 60 that covers a portion of the path limiting member 40 in the length direction.

[0077] The main body 51, for example, has a bent shape that bends along the path of the bent portion 11B. The main body 51 covers a portion of the circumferential portion of the outer periphery of the outer member 30. The main body 51, for example, covers approximately half of the outer periphery of the outer member 30. The main body 51, for example, is formed in a generally semi-cylindrical shape.

[0078] The main body 51 has end portions 53 and 54, which are the two circumferential ends of the main body 51. The main body 51 has an insertion port 51X formed by end portions 53 and 54. The insertion port 51X is an opening between end portions 53 and 54. The insertion port 51X opens in a direction orthogonal to the length direction of the path limiting member 50. The insertion port 51X extends along the entire length of the path limiting member 50. The opening width of the insertion port 51X, that is, the shortest distance between end portions 53 and 54, is, for example, equal to or greater than the outer diameter of the outer member 30. The outer member 30 and the path limiting member 40 are inserted into the insertion port 51X in a direction orthogonal to the length direction of the path limiting member 50.

[0079] The covering portion 60 is provided, for example, at one end of the path limiting member 50 in the longitudinal direction. The covering portion 60 covers, for example, the outer periphery of the end 47 of the path limiting member 40. The covering portion 60 has: a covering body portion 61, which is the end of the body portion 51 in the longitudinal direction; and a cover portion 62, connected to the covering body portion 61. The covering body portion 61 is a part of the body portion 51. The cover portion 62 is integrally formed with the covering body portion 61, for example. The cross-sectional shape of the inner surface of the cover portion 62 is formed, for example, along the shape of the outer surface of the outer member 30. The cover portion 62 is, for example, formed in a generally semi-elliptical cylindrical shape.

[0080] like Figure 3 As shown, the cover 62 partially covers the insertion port 51X of the main body 51 in the longitudinal direction of the path limiting member 50. For example, the cover 62 covers the insertion port 51X only in the longitudinal direction of the main body 51.

[0081] The covering portion 60, for example, has a hinge portion 63 that connects the covering body portion 61 and the cover portion 62. The hinge portion 63 connects one circumferential end of the covering body portion 61 and one circumferential end of the cover portion 62. One or more locking portions 64 are provided at the other circumferential end of the covering body portion 61. One or more claw portions 65 are provided at the other circumferential end of the cover portion 62.

[0082] The cover 62 can pivot about the hinge 63. 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 62 in the closed position, the claw 65 hooks onto the locking part 64. Thus, the cover 62 remains in the closed position. In this way, the covering body 61 and the cover 62 are connected to each other. With the covering body 61 and the cover 62 connected, the covering part 60 forms an annulus that centrally surrounds the outer periphery of the outer component 30 and the path limiting member 40's end 47. In the closed position, the cover 62 covers the insertion port 51X in the covering body 61 and also covers the insertion port 40X of the end 47.

[0083] (Structure of movement restriction component 70)

[0084] like Figure 2 As shown, the movement limiting member 70 is fitted to the outer periphery of the outer component 30. The movement limiting member 70 restricts the relative movement of the path limiting member 40 relative to the outer component 30 in the longitudinal direction of the outer component 30. The movement limiting member 70 is disposed near the end 48 of the path limiting member 40 in the longitudinal direction of the harness body 11. The movement limiting member 70 is, for example, a metal or resin strapping. In this embodiment, the movement limiting member 70 is a resin strapping. Materials such as polypropylene, polyetheretherketone, and fluoropolymers can be used as materials for the movement limiting member 70.

[0085] The movement limiting member 70 has a belt portion 80 and a locking portion 85 provided at one end of the belt portion 80 in the longitudinal direction. The movement limiting member 70 is, for example, a single component in which the belt portion 80 and the locking portion 85 are formed as one piece.

[0086] The strip 80 is generally formed as an elongated flat plate with a rectangular cross-section. The strip 80 is wound around the outer surface of the outer member 30. The strip 80 extends in a first direction L along the circumference of the outer member 30, has a thickness in a second direction T along the radial direction of the outer member 30, and has a width in a third direction W along the length of the outer member 30.

[0087] The belt portion 80 has a first end portion 81 and a second end portion 82, which are the two ends of the belt portion 80 in the first direction L. The first end portion 81 is connected to the locking portion 85. The second end portion 82 is provided on the side opposite to the first end portion 81 in the first direction L of the belt portion 80. The belt portion 80 has a first end surface 80A and a second end surface 80B, which are the two end surfaces of the belt portion 80 in the second direction T, and a third end surface 80C and a fourth end surface 80D, which are the two end surfaces of the belt portion 80 in the third direction W. When the belt portion 80 is wound around the outer surface of the outer member 30, the first end surface 80A is an inner surface facing the outer surface of the outer member 30, and the second end surface 80B is an outer surface provided on the side opposite to the first end surface 80A in the second direction T. With the strip 80 wrapped around the outer surface of the outer component 30, the third end face 80C is an end face opposite to the end face 48A in the length direction of the path limiting component 40, and the fourth end face 80D is an end face provided in the third direction W on the side opposite to the third end face 80C.

[0088] like Figure 5 As shown, the cross-sectional shape of the belt portion 80 is, for example, rectangular. The belt portion 80 is, for example, sized to not engage with the annular recess 32. For example, the dimension of the belt portion 80 along the third direction W is, for example, sized to not engage with the annular recess 32. The dimension of the belt portion 80 along the second direction T (i.e., the thickness of the belt portion 80) is, for example, smaller than the dimension of the path limiting member 40 along the second direction T (i.e., the thickness of the path limiting member 40). Furthermore, the thickness of the belt portion 80 can be equal to or greater than the thickness of the path limiting member 40.

[0089] like Figure 6 As shown, the belt portion 80 has a plurality of engaging grooves 83. Each engaging groove 83 is provided, for example, on a second end face 80B in the second end portion 82. Each engaging groove 83 is formed in a recessed manner from the second end face 80B. Each engaging groove 83 extends along the third direction W of the belt portion 80. The plurality of engaging grooves 83 are provided at intervals from each other in the first direction L of the belt portion 80. The plurality of engaging grooves 83 are provided, for example, only in the second end portion 82 in the first direction L of the belt portion 80. In other words, in the movement limiting member 70 of this embodiment, the portion of the belt portion 80 in the first direction L in which the engaging grooves 83 are formed is referred to as the second end portion 82.

[0090] like Figure 5As shown, the movement limiting member 70 has a protrusion 90 as a first engaging portion. The protrusion 90 is, for example, provided on the first end face 80A of the belt portion 80. The protrusion 90 protrudes from the first end face 80A of the belt portion 80 toward the outer mounting member 30. The protrusion 90 protrudes from the first end face 80A of the belt portion 80 toward a second direction T. The cross-sectional shape of the protrusion 90 is, for example, rectangular.

[0091] The protrusion 90 is formed to engage with the annular recess 32 of the outer component 30. By engaging with the annular recess 32, the protrusion 90 engages with the inner side of the annular recess 32 or the side of the annular protrusion 31 in the longitudinal direction of the outer component 30. As a result, relative movement of the movement limiting member 70 relative to the outer component 30 can be suppressed in the longitudinal direction of the outer component 30.

[0092] like Figure 6 and Figure 7 As shown, the protrusion 90 extends, for example, along the first direction L of the belt portion 80. The protrusion 90 is partially provided, for example, in the first direction L of the belt portion 80. The protrusion 90 is provided, for example, in the middle portion of the belt portion 80 in the first direction L. The protrusion 90 is not provided at the second end 82 of the belt portion 80. That is, the protrusion 90 is not provided on the first end face 80A of the portion of the belt portion 80 where the engaging groove 83 is provided in the first direction L. The protrusion 90 is not provided, for example, at the first end 81 of the belt portion 80.

[0093] A protrusion 90 is provided partially, for example, in the third direction W of the belt portion 80. The protrusion 90, for example, has a width extending in the third direction W of the belt portion 80. The dimension of the protrusion 90 along the third direction W is smaller than the dimension of the belt portion 80 along the third direction W. Figure 5 As shown, the size of the protrusion 90 along the third direction W is formed to fit into the annular recess 32.

[0094] like Figure 6As shown, the movement limiting member 70 has, for example, one or more (three in this embodiment) first protrusions 91 and one or more (three in this embodiment) second protrusions 92. Each first protrusion 91 protrudes outward (outward) of the belt portion 80 beyond the third end face 80C in the third direction W. Each first protrusion 91 protrudes to the left of the third end face 80C in the third direction W. Each second protrusion 92 protrudes outward of the belt portion 80 beyond the fourth end face 80D in the third direction W. Each second protrusion 92 protrudes to the right of the fourth end face 80D in the third direction W. The plurality of first protrusions 91 are spaced apart from each other in the first direction L of the belt portion 80. The plurality of second protrusions 92 are spaced apart from each other in the first direction L of the belt portion 80. Each first protrusion 91 and each second protrusion 92 are located at different positions in the first direction L of the belt portion 80. For example, in the first direction L of the belt portion 80, a plurality of first protrusions 91 and a plurality of second protrusions 92 are arranged alternately. Each of the first protrusions 91 and each of the second protrusions 92 is not provided at the second end 82 of the belt portion 80.

[0095] Each first protrusion 91 extends along the third direction W. Each first protrusion 91 has a base end portion 91A connected to the belt portion 80, and a top end portion 91B disposed in the third direction W on the side opposite to the base end portion 91A. Each first protrusion 91 is formed in a cantilever shape with the base end portion 91A as the fixed end and the top end portion 91B as the free end. Each first protrusion 91 is spring-like. Each first protrusion 91 is configured to elastically deform in a manner that the top end portion 91B deviates from the base end portion 91A in the second direction T. Each first protrusion 91 is configured, for example, to be able to flex in the second direction T through elastic deformation.

[0096] like Figure 5 As shown, the base end portion 91A of each first protrusion 91 is connected, for example, to the second end face 80B of the belt portion 80. The base end portion 91A protrudes, for example, from the second end face 80B of the belt portion 80 toward the second direction T. The base end portion 91A is integrally formed with the belt portion 80.

[0097] like Figure 6 As shown, the top end portion 91B of each first protrusion 91 has, for example, a wide portion 91C. The width of the wide portion 91C along the first direction L is wider than the width of the first protrusion 91 along the first direction L of the portion excluding the wide portion 91C. The dimension of the wide portion 91C along the first direction L is larger than the dimension of the base end portion 91A along the first direction L. The top surface of the top end portion 91B is, for example, located at a position farther from the third end surface 80C than the side surface of the locking portion 85.

[0098] like Figure 5As shown, the tip portion 91B of each first protrusion 91 can contact the outer surface of the path limiting member 40. For example, the wide portion 91C of the tip portion 91B can contact the outer surface of the path limiting member 40. For example, the end face of the tip portion 91B facing the outer member 30 in the second direction T contacts the outer surface of the path limiting member 40. The tip portion 91B contacts the outer surface of the end portion 48 of the path limiting member 40, for example. When the thickness of the belt portion 80 is thinner than the thickness of the path limiting member 40, the first protrusion 91 contacts the outer surface of the path limiting member 40 in a state of elastic deformation.

[0099] like Figure 6 As shown, each second protrusion 92 has the same structure as the first protrusion 91, except that its protrusion direction is opposite to that of each first protrusion 91; therefore, detailed description is omitted here. Each second protrusion 92 extends in the third direction W in a direction opposite to that of the first protrusion 91. Each second protrusion 92 has a base end portion 92A, which is the same as the base end portion 91A; a top end portion 92B, which is the same as the top end portion 91B; and a wide portion 92C, which is the same as the wide portion 91C.

[0100] The locking portion 85, for example, has a cross-sectional shape larger than that of the belt portion 80. The locking portion 85, for example, protrudes outward in the third direction W compared to the third end face 80C and the fourth end face 80D of the belt portion 80. Figure 2 As shown, the locking part 85 protrudes outward in the second direction T from the second end face 80B of the belt part 80. The locking part 85 is, for example, formed in a cuboid shape.

[0101] like Figure 5 As shown, the locking part 85 has an insertion hole 86 into which the strap part 80 can be inserted. The insertion hole 86 is formed, for example, so that the second end 82 of the strap part 80 can be inserted. A locking claw 87 is provided, for example, on the inner surface of the insertion hole 86. The locking claw 87 is formed to engage with a locking groove 83 provided on the strap part 80. In the movement limiting member 70, the strap part 80 is locked to the locking part 85 by engaging the locking claw 87 of the locking part 85 with one of the plurality of locking grooves 83 provided on the strap part 80. In the movement limiting member 70, for example, the size of the inner circumference of the movement limiting member 70 can be varied by adjusting the degree of insertion of the strap part 80 relative to the locking part 85. Therefore, by adjusting the degree of insertion of the strap part 80 relative to the locking part 85, the size of the inner circumference of the movement limiting member 70 can be made to match the size of the outer circumference of the outer member 30. In addition, in the movement limiting member 70, for example, the tightness of the belt 80 on the external member 30 can be adjusted according to the degree of insertion of the belt 80 relative to the locking part 85.

[0102] With the second end 82 of the belt portion 80 inserted into the insertion hole 86 of the locking portion 85, the movement limiting member 70 is wound around the outer periphery of the outer member 30. The movement limiting member 70 is provided, for example, such that the end face 48A of the path limiting member 40 in the length direction of the outer member 30 is adjacent to the end face 48A in the length direction of the outer member 30. At this time, the third end face 80C of the belt portion 80 faces the end face 48A in the length direction of the outer member 30 and can engage with the end face 48A. The belt portion 80 is wound around the outer periphery of the outer member 30 such that the protrusion 90 provided on the first end face 80A of the belt portion 80 engages with the annular recess 32 of the outer member 30. The belt portion 80 is wound around the outer periphery of the outer member 30 such that the first end face 80A exposed from the protrusion 90 contacts the outer surface of the annular protrusion 31. At this time, the band 80 is wrapped around the outer periphery of the outer member 30, for example, with the top end 91B of each first protrusion 91 overlapping the path limiting member 40 in the radial direction of the outer member 30. Each first protrusion 91 is in contact with the outer surface of the end 48 of the path limiting member 40, for example, in a state of elastic deformation by flexing radially outward of the outer member 30 in the second direction T. For example, each first protrusion 91 is provided in such a way that it presses against the path limiting member 40 from the outside of the path limiting member 40. Furthermore, the locking part 85 is provided, for example, in the circumferential direction of the outer member 30 at a portion corresponding to the insertion port 40X of the path limiting member 40.

[0103] (Structure with limiting component 100)

[0104] like Figure 2 As shown, the wire harness 10 includes, for example, a limiting member 100 that restricts the movement of the path limiting member 50 relative to the outer member 30. The limiting member 100 can be, for example, a resin or metal cable tie, a tightening ring, or adhesive tape. In this embodiment, the limiting member 100 is adhesive tape. The limiting member 100 is formed, for example, by fixing the end of the path limiting member 50 located on the side opposite to the covering portion 60 in the longitudinal direction to the outer surface of the outer member 30. The limiting member 100 is wound around the outer member 30, for example, from the end of the path limiting member 50 in the longitudinal direction. Thus, movement of the path limiting member 50 relative to the outer member 30 can be suppressed in both the longitudinal and circumferential directions of the wire harness body 11.

[0105] Next, the function of this embodiment will be explained.

[0106] A movement limiting member 70 is provided to restrict the relative movement of the path limiting member 40 relative to the outer component 30 in the longitudinal direction of the outer component 30. The movement limiting member 70 has a protrusion 90 that engages with the annular recess 32 of the outer component 30, and a third end face 80C that engages with the end face 48A of the path limiting member 40 in the longitudinal direction. According to this structure, by engaging the protrusion 90 of the movement limiting member 70 with the annular recess 32 of the outer component 30, the protrusion 90 engages with the inner side surface of the annular recess 32 or the side surface of the annular protrusion 31 in the longitudinal direction of the outer component 30. Therefore, the relative movement of the movement limiting member 70 relative to the outer component 30 in the longitudinal direction of the outer component 30 can be suppressed. Furthermore, because the third end face 80C of the movement limiting member 70 is configured to engage with the end face 48A of the path limiting member 40 in the longitudinal direction of the path limiting member 40, the movement of the path limiting member 40 in the longitudinal direction of the outer component 30 can be restricted by this movement limiting member 70. Therefore, relative movement of the path limiting member 40 relative to the outer component 30 and the movement limiting member 70 can be suppressed in the length direction of the outer component 30.

[0107] Next, the effects of this embodiment will be explained.

[0108] (1) A movement limiting member 70 is provided, which has a protrusion 90 that engages with the annular recess 32 of the outer member 30 and a third end face 80C that engages with the end face 48A of the path limiting member 40 in the longitudinal direction. According to this structure, because of the aforementioned function, misalignment of the movement limiting member 70 relative to the outer member 30 in the longitudinal direction of the outer member 30 can be suppressed. Furthermore, misalignment of the path limiting member 40 relative to both the outer member 30 and the movement limiting member 70 in the longitudinal direction of the outer member 30 can be suppressed. Therefore, the positional accuracy of the path limiting member 40 relative to the outer member 30 can be improved, and consequently, the positional accuracy of the path limiting member 40 relative to the wire harness body 11 can be improved. As a result, the path limiting member 40 can be appropriately positioned at the desired location of the wire harness body 11, specifically for the straight section 11A, and the path of the straight section 11A can be appropriately restricted using the path limiting member 40. In other words, deviation of the path limiting member 40 from the straight section 11A relative to the wire harness body 11 can be appropriately suppressed.

[0109] (2) In addition, the movement of the path limiting member 40 in the length direction of the outer component 30 can be suppressed, so that the path limiting member 40 caused by the movement can be appropriately suppressed from disengaging from the path limiting member 50.

[0110] (3) The insertion port 40X of the path limiting member 40 opens in a direction orthogonal to the length direction of the path limiting member 40 and extends along the entire length of the path limiting member 40. Therefore, after end processing such as assembling connectors C1, C2, etc., at the ends of the wire member 20 in the length direction, the path limiting member 40 can be assembled to the outer member 30 through the insertion port 40X. This allows for the subsequent installation of the path limiting member 40, thus improving the assembly workability of the wire harness 10.

[0111] (4) The movement limiting member 70 is a strapping band having a strap portion 80 and a locking portion 85. According to this structure, the movement limiting member 70, acting as a strapping band, can limit the relative movement of the path limiting member 40 relative to the outer component 30 in the longitudinal direction of the outer component 30. In the strapping band, because the strap portion 80 can be easily wrapped around the outer periphery of the outer component 30, the assembly workability of the wire harness 10 can be improved.

[0112] (5) The tape portion 80 is sized to not engage with the annular recess 32. Therefore, the tape portion 80 can be wound around the outer surface of the outer member 30 in a state where the first end face 80A of the tape portion 80 contacts the outer surface of the outer member 30, specifically the outer surface of the annular protrusion 31. As a result, the radial movement restriction member 70 of the outer member 30 can be easily positioned, and the tape portion 80 can be stably wound around the outer surface of the outer member 30.

[0113] (6) A first protrusion 91 is provided on the movement limiting member 70, protruding outward from the third end face 80C of the belt portion 80 and capable of contacting the outer surface of the path limiting member 40. This first protrusion 91 allows the path limiting member 40 to be covered from the outside. Therefore, movement of the path limiting member 40 across the movement limiting member 70 in the longitudinal direction of the outer member 30 can be appropriately suppressed. Thus, misalignment of the path limiting member 40 relative to the outer member 30 in the longitudinal direction of the outer member 30 can be appropriately suppressed.

[0114] (7) The first protrusion 91 can elastically deform such that its tip 91B deviates from its base end 91A in a second direction T. Therefore, even if, for example, the size of the path limiting member 40 changes, the tip 91B of the first protrusion 91 can properly contact the outer surface of the path limiting member 40 by changing the amount of elastic deformation of the first protrusion 91. In other words, by changing the amount of elastic deformation of the first protrusion 91, a single movement limiting member 70 can be shared for various path limiting members 40 with different sizes. Here, for example, when the thickness of the path limiting member 40 changes, the size of the path limiting member 40 changes. Therefore, by configuring the first protrusion 91 to be elastically deformable, a single movement limiting member 70 can be shared for various path limiting members 40 with different thicknesses.

[0115] (8) The movement limiting member 70 has a plurality of first protrusions 91 spaced apart from each other in the first direction L of the belt portion 80. The top end portion 91B of each first protrusion 91 has a wide portion 91C, the dimension of the wide portion 91C along the first direction L being larger than the dimension of the base end portion 91A along the first direction L, and can contact the outer surface of the path limiting member 40. According to this structure, the outer surface of the path limiting member 40 is covered by the wide portions 91C of the plurality of first protrusions 91. Therefore, within a wide range in the circumferential direction of the outer member 30, that is, in the first direction L, the plurality of first protrusions 91 can cover the path limiting member 40 from the outside. As a result, movement of, for example, the path limiting member 40 across the movement limiting member 70 in the longitudinal direction of the outer member 30 can be more appropriately suppressed.

[0116] (9) The movement limiting member 70 has a first protrusion 91 and a second protrusion 92 that protrude toward both sides of the belt portion 80 in the third direction W. Therefore, when the movement limiting member 70 is assembled to the outer periphery of the outer component 30, the constraint of the orientation of the belt portion 80 in the third direction W can be eliminated. Even if the movement limiting member 70 is assembled to the outer surface of the outer component 30 in a manner that, for example, the fourth end face 80D of the belt portion 80 is opposite to the end face 48A in the longitudinal direction of the path limiting member 40, the second protrusion 92 can contact the outer surface of the path limiting member 40. As a result, the assembly workability of the movement limiting member 70 can be improved, and thus the assembly workability of the wire harness 10 can be improved.

[0117] (10) A plurality of engaging grooves 83 are provided at the second end 82 of the belt portion 80, and engaging claws 87 are provided on the inner surface of the insertion hole 86 of the locking portion 85. According to this structure, by inserting the second end 82 of the belt portion 80 into the insertion hole 86 of the locking portion 85, and engaging the engaging claws 87 of the locking portion 85 with one of the engaging grooves 83, the belt portion 80 can be locked to the locking portion 85. At this time, by changing the degree of insertion of the belt portion 80 relative to the locking portion 85, the size of the inner circumference of the movement limiting member 70 can be made consistent with the external size of the outer component 30. In other words, by adjusting the degree of insertion of the belt portion 80 relative to the locking portion 85, a single movement limiting member 70 can be used for various outer components 30 with different external sizes.

[0118] (11) The second end 82 of the belt portion 80, which has a locking groove 83 in the first direction L, does not have a protrusion 90. Therefore, the engagement of the locking groove 83 and the locking claw 87 can be prevented from being blocked by the protrusion 90.

[0119] (12) The thickness of the belt portion 80 is made thinner than the thickness of the path limiting member 40. According to this structure, the following can be prevented: due to the provision of the movement limiting member 70, the wire harness 10 becomes larger in the radial direction of the outer component 30.

[0120] (13) The path limiting member 40 has a protrusion 45 that protrudes from the inner surfaces of the ends 41 and 42 and contacts the outer surface of the outer member 30. According to this structure, for example, the outer member 30 is pressed from the outside of the outer member 30 by the protrusion 45. Therefore, the path limiting member 40 can be appropriately prevented from disengaging from the outer member 30 through the insertion port 40X.

[0121] (Other implementation methods)

[0122] 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.

[0123] • The structure of the movement limiting member 70 in the above embodiments can be appropriately modified. For example, as long as the movement limiting member 70 has a first engaging portion that engages with the annular recess 32 and a second engaging portion that engages with the end face 48A in the length direction of the path limiting member 40, other structures are not particularly limited.

[0124] ·For example Figure 8 As shown, the second protrusion 92 in the movement limiting member 70 can also be omitted. In this modified example, the movement limiting member 70 only has a first protrusion 91 that protrudes outward from the third end face 80C of the belt portion 80.

[0125] ·For example Figure 9As shown, the first protrusion 91 and the second protrusion 92 in the movement limiting member 70 can also be omitted. Even in this case, the third end face 80C of the belt portion 80 can be engaged with the end face 48A of the path limiting member 40 in the length direction of the outer member 30. Therefore, misalignment of the path limiting member 40 relative to the outer member 30 can be suppressed in the length direction of the outer member 30.

[0126] ·For example Figure 10 As shown, the movement limiting member 70 may also have multiple protrusions 90. For example, multiple (two in this case) protrusions 90 may be provided on the first end face 80A of the belt portion 80. The multiple protrusions 90 are provided at intervals from each other, for example, in the third direction W. The multiple protrusions 90 are formed to engage with mutually different annular recesses 32. For example, two protrusions 90 are formed to engage with two adjacent annular recesses 32 in the longitudinal direction of the outer member 30.

[0127] According to this structure, the two protrusions 90 respectively engage with the two annular recesses 32, and in the longitudinal direction of the outer component 30, the two protrusions 90 engage with the side of the annular protrusions 31. Therefore, relative movement of the movement limiting member 70 relative to the outer component 30 can be appropriately suppressed in the longitudinal direction of the outer component 30. Thus, misalignment of the movement limiting member 70 relative to the outer component 30 can be appropriately suppressed in the longitudinal direction of the outer component 30.

[0128] In the above embodiments, the cross-sectional shape of the strip portion 80 and the protrusion 90 may also be formed into a T-shape, but it is not limited to this. The cross-sectional shape of the strip portion 80 and the protrusion 90 can be appropriately changed.

[0129] ·For example Figure 11 As shown, the cross-sectional shape of the belt portion 80 and the protrusion 90 can also be formed into an L-shape. In this modified example, the movement limiting member 70 has a protrusion 90 at its end in the third direction W on the side of the fourth end face 80D of the first end face 80A of the belt portion 80. For example, one end face of the protrusion 90 in the third direction W is formed to be flush with the fourth end face 80D of the belt portion 80. Even in this case, the protrusion 90 engages with the annular recess 32. In addition, the third end face 80C of the belt portion 80 is formed to engage with the end face 48A of the path limiting member 40 in the length direction of the outer member 30. As a result, misalignment of the movement limiting member 70 relative to the outer member 30 in the length direction of the outer member 30 can be suppressed, and misalignment of the path limiting member 40 relative to the outer member 30 can also be suppressed.

[0130] ·For example Figure 12As shown, the movement limiting member 70 may also have a protrusion 93 that protrudes outward from the third end face 80C of the belt portion 80 in the third direction W. The protrusion 93 protrudes, for example, from the third end face 80C toward a direction (here, to the right) in the third direction W. The protrusion 93 is partially provided on the third end face 80C of the belt portion 80 in the second direction T. The protrusion 93 is provided at an end of the third end face 80C of the belt portion 80 on the side of the second end face 80B in the second direction T. For example, one end face of the protrusion 93 in the second direction T is formed to be flush with the second end face 80B. The protrusion 93 is, for example, at an end face of the belt portion 80 excluding the second end face 82 (see reference) in the first direction L. Figure 6 The portion other than the path limiting member 40 is formed in a manner that extends continuously. The protrusion 93 is formed, for example, to contact the outer surface of the end 48 of the path limiting member 40. In this modified example, the thickness of the strip portion 80 is greater than the thickness of the path limiting member 40. In this modified example, the dimension of the protrusion 90 along the third direction W is equal to the dimension of the strip portion 80 along the third direction W.

[0131] According to this structure, the protrusion 90 engages with the annular recess 32, and the third end face 80C of the band 80 is formed to engage with the end face 48A of the path limiting member 40 in the length direction of the outer member 30. Thus, misalignment of the movement limiting member 70 relative to the outer member 30 in the length direction of the outer member 30 can be suppressed, and misalignment of the path limiting member 40 relative to the outer member 30 can also be suppressed. Furthermore, a protrusion 93 is provided on the movement limiting member 70 that contacts the outer surface of the path limiting member 40. Because the protrusion 93 can cover the path limiting member 40 from the outside, movement of the path limiting member 40 across the movement limiting member 70 in the length direction of the outer member 30 can be appropriately suppressed.

[0132] • The cross-sectional shape of the strip 80 and the protrusion 90 can also be formed into an I-shape. For example, it can also be from... Figure 12 The protrusion 93 is omitted from the shown movement restriction member 70.

[0133] ·For example Figure 13 As shown, it can also be set from Figure 12The movement limiting member 70 shown has a protrusion 94 protruding from the fourth end face 80D of the belt portion 80 toward a direction (to the left) in the third direction W. The protrusion 94 is partially provided on the fourth end face 80D of the belt portion 80 in the second direction T, for example. The protrusion 94 is provided at the end of the fourth end face 80D of the belt portion 80 on the side of the first end face 80A in the second direction T. For example, one end face of the protrusion 94 in the second direction T is formed to be flush with the first end face 80A. The protrusion 94 extends, for example, along the first direction L. The protrusion 94 extends, for example, along the entire length of the belt portion 80 in the first direction L. The protrusion 94 is formed to be able to contact the outer surface of the annular protrusion 31, for example. The dimension of the protrusion 94 along the second direction T is smaller than the dimension of the belt portion 80 along the second direction T. For example, the dimension of the protrusion 94 along the second direction T can be equal to or greater than the dimension of the belt portion 80 along the second direction T. Furthermore, the protrusion 94 can also be a part of the belt portion 80.

[0134] • The protrusion 90 may extend continuously along the first direction L of the belt portion 80, but this is not a limitation. For example, the protrusion 90 may extend discontinuously along the first direction L of the belt portion 80. That is, the protrusion 90 may be provided partially at predetermined intervals along the first direction L of the belt portion 80.

[0135] • The wide portion 91C in the first protrusion 91 can also be omitted. For example, the first protrusion 91 can be formed such that its width along the first direction L extends the entire length of the first protrusion 91 in the third direction W. Furthermore, the second protrusion 92 can also be modified.

[0136] Alternatively, the engaging slot 83 can be set on the first end face 80A.

[0137] • In the movement restriction member 70, the following structure may also be provided: the third engaging part of the belt part 80 is provided as the engaging groove 83, the fourth engaging part of the locking part 85 is provided as the engaging claw 87, and the third engaging part and the fourth engaging part engage with each other, but these concave and convex relationships may also be reversed.

[0138] • The limiting member 100 can also be changed to the movement limiting member 70. That is, the movement limiting member 70 can also be used as a movement limiting member that limits the relative movement of the path limiting member 50 relative to the outer member 30 in the length direction of the outer member 30.

[0139] • Restriction component 100 can also be omitted.

[0140] • The movement restriction member 70 can be embodied as a strap with a band portion 80 and a locking portion 85, but is not limited to this. For example, the movement restriction member 70 can also be changed to a ring member with a fixed inner circumference.

[0141] • The structure of the path limiting member 50 in the above embodiment can be appropriately modified. For example, the bending shape in the main body 51 can be appropriately modified. For example, the cross-sectional shape of the inner surface of the main body 51 can be appropriately modified.

[0142] • In the path limiting member 50, the main body 51 (covering the main body 61) and the cover 62 are formed as one piece, but this is not a limitation; the main body 51 and the cover 62 can also be separated. That is, the main body 51 and the cover 62 can also be separate parts.

[0143] • The cover 62 in the path limiting component 50 can also be omitted.

[0144] • In the path limiting member 50, a cover portion that is connected to the main body 51 other than the main body 61 may also be provided.

[0145] • The path limiting member 50 may also be omitted. In this case, a movement limiting member 70 may be provided at each of the ends 47 and 48 on both sides of the path limiting member 40 in the length direction.

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

[0147] Alternatively, each protrusion 45 may be positioned circumferentially on the path limiting member 40 at a position further away from the insertion port 40X than the top end 41A of the end 41.

[0148] • Protrusions 45 may also be provided locally along the length of the path limiting member 40.

[0149] • At least one of the two protrusions 45 can also be omitted.

[0150] • In the path limiting member 40, a second protrusion may also be provided, protruding from the inner surface of the connecting portion 43 and contacting the outer surface of the outer component 30. With 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 path limiting member 40 can be suppressed.

[0151] • In the path limiting member 40, a groove extending along the length direction may also be provided on the outer surface of the connecting portion 43. According to this structure, the connecting portion 43 can easily deform outwards from the groove, thereby easily enlarging the insertion port 40X. As a result, it can help improve the assemblability of the path limiting member 40.

[0152] • The radial thickness of the connecting part 43 can also vary in the circumferential direction.

[0153] • The cross-sectional shape of the connecting part 43 is not limited to a circular arc shape, but can be changed to, for example, an elliptical arc shape, a U-shaped shape, etc.

[0154] In the above embodiments, the path limiting members 40 and 50 are harder than the outer member 30, but this is not the case; they may also be of equal or less hardness than the outer member 30. That is, the path limiting members 40 and 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 path limiting members 40 and 50.

[0155] • The outer component 30 may be, for example, an outer component having a metal layer containing a metal material disposed on the outer surface of a resin bellows.

[0156] In the above embodiment, the outer component 30 is specifically embodied as a corrugated pipe made of resin, but it is not limited to this. For example, the outer component 30 is not limited to a corrugated pipe as long as it has a corrugated shape with annular protrusions 31 and annular recesses 32 alternately connected in the length direction of the outer component 30. In addition, the corrugated shape with annular protrusions 31 and annular recesses 32 alternately connected may only be provided in a portion of the length direction of the outer component 30.

[0157] • The outer component 30 may also be an outer component having a slit extending in the length direction of the outer component 30.

[0158] • 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.

[0159] • In the wire component 20, the electromagnetic shielding component is embodied as a braided component 25, but it is not limited to this. For example, the electromagnetic shielding component in the wire component 20 may also be embodied as a metal foil.

[0160] • The braided component 25 in the wire component 20 can also be omitted.

[0161] • 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 be one or more.

[0162] • 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.

[0163] • 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 are not particularly limited as long as they are electrical devices mounted on the vehicle V.

[0164] The embodiments disclosed herein are illustrative in all respects and not restrictive. The scope of the invention is not shown by the foregoing but by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
