[0020] [Description of embodiments of this disclosure]

[0021] First, the implementation methods of this disclosure are listed and explained.

[0022] [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 the outer periphery of a connecting portion of the path limiting member, the path limiting member having: a first main body portion covering a portion of the outer periphery of the outer member; and a first insertion port opening in a direction orthogonal to the length direction of the first main body portion and extending along the entire length direction of the first main body portion, the assembly member having a covering portion covering the outer periphery of the connecting portion, the connecting portion having a first engaging portion provided on the first main body portion, and the covering portion having a second engaging portion engaging with the first engaging portion in the circumferential direction of the wire harness body.

[0023] 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. At this time, a first engaging portion is provided in the first main body portion of the connecting portion, and a second engaging portion is provided in the covering portion that engages with the first engaging portion in the circumferential direction of the wire harness body. By interlocking these first and second engaging portions, relative movement of the path limiting member relative to the assembly member in the circumferential direction of the wire harness body can be suppressed. That is, by interlocking the first and second engaging portions, circumferential rotation of the path limiting member relative to the assembly member can be suppressed. Therefore, misalignment of the path limiting member relative to the assembly member in the circumferential direction of the wire harness body can be suppressed, and the positional accuracy of the path limiting member relative to the assembly member can be improved.

[0024] [2] Preferably, one of the first engaging portion and the second engaging portion is a recess, and the other of the first engaging portion and the second engaging portion is a protrusion that engages with the recess. According to this structure, the first engaging portion and the second engaging portion engage with each other in the circumferential direction of the wire harness body through the interlocking of the first engaging portion and the second engaging portion. Thus, relative movement of the path limiting member relative to the assembly member can be suppressed in the circumferential direction of the wire harness body.

[0025] [3] Preferably, the first engaging portion extends along the length direction of the wire harness body, and the second engaging portion extends along the length direction of the wire harness body. According to this structure, the first engaging portion extends along the length direction of the wire harness body, and the second engaging portion extends along the length direction of the wire harness body. Therefore, even if, for example, the connecting portion and the covering portion are misaligned in the length direction of the wire harness body, the first engaging portion and the second engaging portion can be properly engaged in the circumferential direction of the wire harness body. Thus, relative movement of the path limiting member relative to the assembly member in the circumferential direction of the wire harness body can be appropriately suppressed.

[0026] [4] Preferably, the first engaging portion extends along the entire length of the connecting portion in the longitudinal direction, and the second engaging portion extends along the entire length of the covering portion in the longitudinal direction. According to this structure, the first engaging portion extends along the entire length of the connecting portion, and the second engaging portion extends along the entire length of the covering portion in the longitudinal direction. Therefore, even in cases where, for example, the connecting portion and the covering portion are misaligned in the longitudinal direction of the wire harness body, the first engaging portion and the second engaging portion can be properly engaged in the circumferential direction of the wire harness body. Thus, relative movement of the path limiting member relative to the assembly member can be appropriately suppressed in the circumferential direction of the wire harness body.

[0027] [5] Preferably, the first engaging portion is a recess provided on the outer surface of the first main body, and the second engaging portion is a protrusion protruding from the inner surface of the assembly member toward the path limiting member and engaging with the recess. The recess does not penetrate the first main body. According to this structure, the recesses and protrusions engage with each other in the circumferential direction of the wire harness body by engaging with the recess that does not penetrate the first main body and the protrusion provided on the inner surface of the assembly member. Thus, relative movement of the path limiting member relative to the assembly member can be suppressed in the circumferential direction of the wire harness body.

[0028] [6] Preferably, the path limiting member has: a first end and a second end, disposed at both circumferential ends of the first main body and forming the first insertion port; a first protrusion, protruding from the inner surface of at least one of the first end and the second end and capable of contacting the outer surface of the outer component; and a second protrusion, protruding from the inner surface of the portion of the first main body in which the recess is provided and capable of contacting the outer surface of the outer component. According to this structure, the path limiting member has a first protrusion that protrudes from the inner surface of at least one of the first end and the second end and is capable of contacting the outer surface of the outer component. Using this first protrusion, for example, the outer component can be pressed from the outside of the outer component. Therefore, the path limiting member can be appropriately prevented from falling off the outer component through the first insertion port. In addition, the path limiting member has a second protrusion that protrudes from the inner surface of the first main body and is capable of contacting the outer surface of the outer component. Therefore, both the first protrusion and the second protrusion can be made to contact the outer surface of the outer component. This can suppress the swaying of the path limiting component relative to the external component.

[0029] [7] 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 length direction, and the covering portion is provided at the end of the second path limiting member in the length direction. According to this structure, the first path limiting member and the second path limiting member are partially overlapped in the length direction of the wire harness body. Specifically, in the length direction of the wire harness body, the connecting portion provided at the end of the first path limiting member in the length direction and the covering portion provided at the end of the second path limiting member in the length direction are overlapped. Furthermore, by the first engaging portion provided at the connecting portion and the second engaging portion provided at the covering portion engaging with each other, the relative movement of the first path limiting member relative to the second path limiting member in the circumferential direction of the wire harness body can be suppressed. Therefore, the misalignment of the first path limiting member relative to the second path limiting member in the circumferential direction of the wire harness body can be suppressed, and the positional accuracy of the first path limiting member relative to the second path limiting member can be improved.

[0030] [8] Preferably, the first path limiting member limits the path of the straight portion, which is a straight section forming a straight line 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 section in the path of the wire harness body. According to this structure, the first path limiting member limits the path of the straight portion, and the second path limiting member limits the path of the bent portion. Therefore, it is possible to prevent the paths of the straight portion and the bent portion from deviating from their desired paths.

[0031] [9] Preferably, the assembly member is a fixing member having the covering portion and a fixing portion connected to and fixed to the vehicle body, the covering portion surrounding and holding the wiring harness body and the path limiting member. According to this structure, the wiring harness body and the path limiting member are held by the covering portion, and the fixing portion connected to the covering portion is fixed to the vehicle body. Therefore, by fixing the fixing portion to the vehicle body, the wiring harness body and the path limiting member can be fixed to the vehicle body.

[0032]

[10] 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 and a cover portion connected to the second main body portion. According to this structure, although the covering portion is formed as an annular ring, by having a second main body portion and a cover portion as the covering portion, the assembly component including the covering portion can be subsequently assembled to the connecting portion and the outer component. This improves the ease of assembly of the wire harness.

[0033] [Details of the embodiments of this disclosure]

[0034] The following is a reference to the appendix. Figure 1Specific examples of the wire harness disclosed herein will be described. In the accompanying drawings, for ease of explanation, parts of the structure are sometimes exaggerated or simplified. Furthermore, the dimensional ratios of the various parts may differ in the various drawings. The terms "orthogonal" and "full length" as used in this specification include not only cases where they are strictly orthogonal and of full length, but also cases where they are approximately orthogonal and of full length within the range that achieves the effect of this embodiment. Furthermore, the term "cylindrical" as used in this specification includes not only a cylindrical shape with a continuous circumferential wall, but also shapes formed by combining multiple components to form a cylindrical shape, and shapes such as a C-shape with a notch in a portion of the circumference. In addition, the shape of "cylindrical" includes, but is not limited to, circles, ellipses, and polygons with pointed or rounded corners. Furthermore, the term "ring-shaped" as used in this specification sometimes refers to any structure forming a ring, or a continuous shape without ends, and a structure with a gap, generally a ring shape, such as a C-shape. Furthermore, the shape of "ring-shaped" includes, but is not limited to, circles, ellipses, and polygons with pointed or rounded corners.

Additionally, "opposite" in this specification includes both cases where a component different from the two parts is sandwiched between the two parts, and cases where nothing is sandwiched between the two parts. 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.

[0035] (Overall structure of wire harness 10)

[0036] 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.

[0037] 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.

[0038] The wiring harness 10 has a wiring harness body 11. The wiring harness body 11 has a wire member 20 and a cylindrical outer casing 30 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.

[0039] like Figure 2 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.

[0040] (Structure of electrical component 20)

[0041] like Figure 3 and Figure 4 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] (Structure of external component 30)

[0048] 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, the outer casing 30 is sealed throughout its entire circumference. The outer casing 30 has the function of protecting the wire component 20 from, for example, flying objects or water droplets.

[0049] The outer component 30 is flexible and can be easily bent. Examples of flexible outer components 30 include resin corrugated tubes and rubber waterproof caps. In this embodiment, the outer component 30 is a resin corrugated tube with an annular protrusion 31 and an annular recess 32 alternately connected along the length of the outer component 30. Each of the annular protrusion 31 and an annular recess 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 The external component 30 is shown in a simplified diagram.

[0050] (Structure of the first path limiting member 40 and the second path limiting member 50)

[0051] 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. For example, the first path limiting member 40 and the second path limiting member 50 each assist the outer member 30 to prevent the wire harness body 11 from deviating from the desired path due to its own weight or other deflections. The first path limiting member 40 and the second path limiting member 50 are each locally provided along the length direction of the wire harness body 11. Furthermore, one or more of the first path limiting member 40 and the second path limiting member 50 are provided depending on the path of the wire harness body 11.

[0052] The first path limiting member 40 is, for example, fitted to the outer periphery of the outer component 30 in the straight section 11A, where the straight section 11A is a straight portion forming a straight line in the path of the wire harness body 11. The first path limiting member 40 limits the path of the wire harness body 11 in the straight section 11A. Here, the straight section 11A is a portion where the path of the wire harness body 11 extends in a straight line in one direction. The second path limiting member 50 is, for example, fitted to the outer periphery of the outer component 30 in the bending section 11B, where the bending section 11B is a bent portion in the path of the wire harness body 11. The second path limiting member 50 limits the path of the wire harness body 11 in the bending section 11B. Here, the bending section 11B is a portion where the path of the wire harness body 11 is bent in a two-dimensional or three-dimensional manner.

[0053] (Structure of the first path restriction component 40)

[0054] 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 periphery of the outer member 30. 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 generally C-shaped. The cross-sectional shape of the first path limiting member 40 is, for example, the same along its entire length. Figure 2 As shown, the first path limiting member 40 extends, for example, along the path of the straight portion 11A, and is formed into a shape that extends in a straight line in one direction.

[0055] The first path limiting member 40 is made of, for example, metal or resin. In this embodiment, the first path limiting member 40 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used as the material for the first path limiting member 40. The first path limiting member 40 can be manufactured, for example, by extrusion molding, injection molding, etc.

[0056] The first path limiting member 40 has a first insertion port 40X that opens in a direction orthogonal to the length direction of the first path limiting member 40. The first path limiting member 40 has a first end portion 41 and a second end portion 42 forming the first insertion port 40X, the first end portion 41 and the second end portion 42 being the two circumferential ends of the first path limiting member 40. The first path limiting member 40 has a first main body portion 43 connecting the first end portion 41 and the second end portion 42. In other words, the first path limiting member 40 has: a first main body portion 43 that covers a portion of the circumferential direction of the outer fitting member 30; a first end portion 41 and a second end portion 42 provided at the two ends of the first main body portion 43; and a first insertion port 40X formed through the first end portion 41 and the second end portion 42.

[0057] like Figure 4 As shown, the first main body portion 43 constitutes the main part of the first path limiting member 40. The radial thickness of the first main body portion 43 is the same as that of the first path limiting member 40 in the circumferential direction. The cross-sectional shape of the first main body portion 43 is formed, for example, along the shape of the outer surface of the outer member 30. The cross-sectional shapes of the first end portion 41, the second end portion 42, and the first main body portion 43 are formed, for example, arcuate.

[0058] The first end 41 and the second end 42 are disposed opposite to each other in the circumferential direction of the first main body 43. The first end 41 and the second end 42 are disposed separately from each other in the circumferential direction of the first main body 43, separated by the first insertion port 40X. In other words, in the circumferential direction of the first path limiting member 40, the gap between the first end 41 and the second end 42 is formed as the first insertion port 40X. Thus, the first path limiting member 40 is formed in a C-shape with the first insertion port 40X in a portion of the circumferential direction of the first main body 43.

[0059] The first end 41 has a tip 41A. The second end 42 has a tip 42A. Tips 41A and 42A form a first insertion port 40X. Tips 41A and 42A 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 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.

[0060] The first path limiting member 40 has, for example, a first protrusion 45 protruding from the inner surfaces of the first end 41 and the second end 42. Each first 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 first protrusion 45 contacts, for example, the outer surface of the annular protrusion 31 of the outer member 30. The two first protrusions 45 protrude from the inner surfaces of the top ends 41A and 42A, for example. The cross-sectional shape of each first protrusion 45 is, for example, formed as a curved shape. In this embodiment, the cross-sectional shape of each first protrusion 45 is formed as a semi-circular shape. Each first protrusion 45 extends in the longitudinal direction of the first path limiting member 40. Each first protrusion 45 extends, for example, along the entire length of the first path limiting member 40 in the longitudinal direction.

[0061] The first path limiting member 40 has, for example, one or more (two in this embodiment) second protrusions 46 protruding from the inner surface of the first main body 43. Each second protrusion 46 protrudes from the inner surface of the first main body 43 toward the outer member 30 and can contact the outer surface of the outer member 30. Each second protrusion 46, for example, contacts the outer surface of the annular protrusion 31 of the outer member 30. The two second protrusions 46 are spaced apart from each other circumferentially from the first path limiting member 40. The cross-sectional shape of each second protrusion 46 is formed as a curved shape. The cross-sectional shape of each second protrusion 46 in this embodiment is, for example, formed as a semi-circular shape. Each second protrusion 46 extends along the entire length of the first path limiting member 40, for example.

[0062] Each of the first protrusions 45 and each of the second protrusions 46 presses against the outer member 30 from the outside of the outer member 30, for example. The outer member 30 is elastically clamped by each of the first protrusions 45 and each of the second protrusions 46, for example. As a result, the connection between the first path limiting member 40 and the outer member 30 becomes secure. Therefore, movement of the first path limiting member 40, which is fitted to the outer periphery of the outer member 30, in the longitudinal direction of the outer member 30 can be suppressed.

[0063] Because each of the first protrusions 45 and each of the second protrusions 46 is in contact with the outer surface of the outer component 30, a gap is generated between the inner surface of the first main body 43 and the outer surface of the outer component 30. This gap is generated along the entire length of the first path limiting component 40.

[0064] The opening width of the first insertion port 40X, that is, the shortest distance between the first end 41 and the second end 42, is, for example, less than the outer diameter of the outer component 30. Figure 3As shown, the first insertion port 40X extends along the entire length of the first main body portion 43. That is, the first insertion port 40X is formed such that it opens in a direction orthogonal to the length direction of the first main body portion 43 and opens at both ends in the length direction of the first main body portion 43.

[0065] By inserting the outer component 30 into the first insertion port 40X 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 first insertion port 40X. 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 first insertion port 40X 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.

[0066] 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.

[0067] like Figure 4 As shown, the connecting portion 47 has one or more recesses 48 serving as the first engaging portion. In this embodiment, the connecting portion 47 has two recesses 48. Each recess 48 is provided on the outer surface of the first main body portion 43 in the connecting portion 47. Each recess 48 is, for example, provided on the outer surface of the portion of the first main body portion 43 where each second protrusion 46 is provided. Each recess 48 is, for example, provided at a position where it overlaps with each second protrusion 46 in the radial direction of the first path limiting member 40. Each recess 48 is formed such that it is recessed from the outer surface of the first main body portion 43 towards the radially inward side of the first path limiting member 40. Each recess 48 is a recess that does not penetrate the first main body portion 43 radially. The cross-sectional shape of each recess 48 is formed as a curved shape. In this embodiment, the cross-sectional shape of each recess 48 is formed as a semi-circular shape. Figure 3 As shown, each recess 48 extends, for example, along the length direction of the wire harness body 11. Each recess 48 extends, for example, along the entire length direction of the connecting portion 47. Each recess 48 extends, for example, along the entire length direction of the first main body portion 43.

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

[0069] like Figure 2As shown, 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. The second path limiting member 50 can be manufactured, for example, by injection molding.

[0070] The second path limiting member 50 has a second main body portion 51 and a covering portion 60 that covers a portion of the first path limiting member 40 along its length. The second main body portion 51, for example, has a bent shape that bends along the path of the bending portion 11B. The second main body portion 51 covers a portion of the circumferential direction of the outer periphery of the outer member 30. For example, the second main body portion 51 covers approximately half of the outer periphery of the outer member 30. The cross-sectional shape of the second main body portion 51 is, for example, formed along the shape of the outer surface of the outer member 30. The cross-sectional shape of the second main body portion 51 is, for example, formed as an arc or a U-shape. The second main body portion 51 is, for example, formed as a generally semi-cylindrical shape.

[0071] The second main body portion 51 has a third end portion 53 and a fourth end portion 54, which are the two circumferential ends of the second main body portion 51. The second main body portion 51 has a second insertion port 51X formed through the third end portion 53 and the fourth end portion 54. The second insertion port 51X is an opening between the third end portion 53 and the fourth end portion 54. The second insertion port 51X opens in a direction orthogonal to the length direction of the second main body portion 51. The second insertion port 51X extends along the entire length direction of the second main body portion 51. That is, the second insertion port 51X opens in a direction orthogonal to the length direction of the second main body portion 51, and opens at both ends in the length direction of the second main body portion 51. The opening width of the second insertion port 51X, that is, the shortest distance between the third end portion 53 and the fourth end portion 54, is, for example, equal to or larger than the outer diameter of the first path limiting member 40. The external component 30 and the first path limiting component 40 are inserted into the second insertion port 51X in a direction orthogonal to the length direction of the second path limiting component 50.

[0072] The covering portion 60 is provided, for example, at one end of the second path limiting member 50 in the longitudinal direction. The covering portion 60 is provided, for example, overlapping the connecting portion 47 in the radial direction of the outer member 30.

[0073] like Figure 4 As shown, the covering portion 60 covers the outer periphery of the connecting portion 47. The covering portion 60 is, for example, formed as an annular ring that surrounds the outer periphery of the connecting portion 47 and the outer periphery of the outer fitting member 30 on which the connecting portion 47 is fitted, throughout the entire circumference.

[0074] The covering portion 60 has a covering body portion 61 and a cover portion 62 connected to the covering body portion 61. The covering body portion 61 is the end portion of the second body portion 51 in the longitudinal direction. The covering body portion 61 is a part of the second 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, a shape corresponding to the outer surface of the outer component 30. The cross-sectional shape of the inner surface of the cover portion 62 is, for example, an arc shape or an elliptical arc shape. The cover portion 62 is, for example, formed as a generally semi-elliptical cylinder.

[0075] like Figure 2 As shown, the cover 62 partially covers the second insertion port 51X of the second main body 51 in the length direction of the second path limiting member 50. For example, the cover 62 only covers the second insertion port 51X of the main body 51 in the length direction of the second main body 51.

[0076] like Figure 3 As shown, the covering portion 60 has, for example, 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.

[0077] 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 member 30 and the connecting part 47. In the closed position, the cover 62 covers the second insertion port 51X in the covering body 61 and the first insertion port 40X in the connecting part 47.

[0078] The covering portion 60 has one or more protrusions 68 serving as the second engaging portion. In this embodiment, the covering portion 60 has two protrusions 68. Each protrusion 68 is formed to engage with each recess 48 in the circumferential direction of the wire harness body 11. Each protrusion 68 is, for example, provided on the inner surface of the covering body portion 61. Each protrusion 68, for example, protrudes from the inner surface of the covering body portion 61 toward the first body portion 43 of the connecting portion 47. Each protrusion 68 is, for example, formed to engage with each recess 48. The cross-sectional shape of each protrusion 68 is, for example, a curved shape. The cross-sectional shape of each protrusion 68 is, for example, a semi-circular shape.

[0079] like Figure 3As shown, each protrusion 68 extends, for example, along the length direction of the wire harness body 11. Each protrusion 68 is longer in the length direction of the wire harness body 11 than in the circumferential direction. Each protrusion 68 is formed, for example, such that its dimension along the length direction of the wire harness body 11 is more than twice its dimension along the circumferential direction. Each protrusion 68 extends, for example, along the entire length of the covering portion 60. Each protrusion 68 is provided only in the second main body portion 51, covering the main body portion 61. Each protrusion 68 is provided partially in the circumferential direction covering the main body portion 61.

[0080] like Figure 4 As shown, when the protrusion 68 and the recess 48 are engaged, the recess 48 and the protrusion 68 engage with each other in the circumferential direction of the harness body 11. Specifically, when the protrusion 68 and the recess 48 are engaged, the inner surface of the recess 48 and the side surface of the protrusion 68 engage with each other in the circumferential direction of the harness body 11. Therefore, the first path limiting member 40 and the second path limiting member 50 become less likely to move relative to each other in the circumferential direction of the harness body 11. As a result, the first path limiting member 40 can be prevented from rotating circumferentially within the second path limiting member 50. Furthermore, when the protrusion 68 and the recess 48 are engaged, the first path limiting member 40 is positioned relative to the second path limiting member 50 in the circumferential direction of the harness body 11. Therefore, the orientation of the first path limiting member 40 relative to the second path limiting member 50, specifically the orientation of the first insertion port 40X, can be adjusted in the circumferential direction of the harness body 11. In other words, the circumferential position of the first insertion port 40X in the first path limiting member 40 is positioned by the recess 48 and the protrusion 68 that engages with the recess 48. In this embodiment, when the protrusion 68 engages with the recess 48, the circumferential position of the first insertion port 40X in the first path limiting member 40 is set towards the cover portion 62 in the covering portion 60. Here, when the connecting portion 47 is engaged with the inner side of the covering body portion 61, a portion of the circumferential direction of the connecting portion 47 protrudes outward (upper side in the figure) from the third end portion 53 and the fourth end portion 54 of the covering body portion 61, that is, from the inner surface side of the cover portion 62. Furthermore, the first end portion 41, the second end portion 42, and the first insertion port 40X in the connecting portion 47 are positioned at a position that protrudes towards the inner surface side of the cover portion 62 from the third end portion 53 and the fourth end portion 54 of the covering body portion 61.

[0081] (Structure of restricting components 71 and 72)

[0082] like Figure 2As shown, the wire harness 10 has, for example, a limiting member 71 that restricts the movement of the first path limiting member 40 relative to the outer member 30, and a limiting member 72 that restricts the movement of the second path limiting member 50 relative to the outer member 30. The limiting members 71 and 72 can be, for example, resin or metal strapping, tightening rings, adhesive tape, etc. In this embodiment, the limiting members 71 and 72 are adhesive tape.

[0083] The limiting member 71 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 to the outer surface of the outer member 30 in the longitudinal direction. The limiting member 71 is wound around the outer member 30 from the end of the first path limiting member 40 in the longitudinal direction. This suppresses movement of the first path limiting member 40 relative to the outer member 3 in both the longitudinal and circumferential directions of the wire harness body 11. The limiting member 72 is formed, for example, by fixing the end of the second path limiting member 50 located on the side opposite to the covering portion 60 to the outer surface of the outer member 30 in the longitudinal direction. The limiting member 72 is wound around the outer member 30 from the end of the second path limiting member 50 in the longitudinal direction. 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.

[0084] Next, the function of this embodiment will be explained.

[0085] Along the length of the wire harness body 11, a connecting portion 47 at the end of the first path limiting member 40 and a covering portion 60 at the end of the second path limiting member 50 are provided overlappingly. In this case, a recess 48 is provided in the first main body portion 43 of the connecting portion 47. Furthermore, a protrusion 68 is provided in the covering portion 60 that engages with the recess 48 in the circumferential direction of the wire harness body 11. Through the interlocking of these recesses 48 and protrusions 68, relative movement of the first path limiting member 40 relative to the second path limiting member 50 in the circumferential direction of the wire harness body 11 can be suppressed.

[0086] Next, the effects of this embodiment will be explained.

[0087] (1) A recess 48 is provided in the first main body portion 43 of the connecting portion 47, and a protrusion 68 is provided in the covering portion 60 that engages with the recess 48 in the circumferential direction of the wire harness body 11. According to this structure, because it achieves the aforementioned effect, circumferential rotation of the first path limiting member 40 relative to the second path limiting member 50 can be suppressed. Therefore, misalignment of the first path limiting member 40 relative to the second path limiting member 50 in the circumferential direction of the wire harness body 11 can be suppressed. Therefore, the positional accuracy of the first path limiting member 40 relative to the second path limiting member 50 can be improved. Here, in this embodiment, the second path limiting member 50 is fixed to the outer member 30 of the wire harness body 11 by a limiting member 72. Therefore, relative movement of the second path limiting member 50 relative to the wire harness body 11 in the circumferential direction of the wire harness body 11 can be 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 can be improved. As a result, the first path limiting member 40 can be appropriately configured in the circumferential direction of the wire harness body 11 in a manner that covers the desired portion of the wire harness body 11.

[0088] Because the rotation of the first path limiting member 40 relative to the second path limiting member 50 can be suppressed in the circumferential direction of the wire harness body 11, for example, the rotation of the first path limiting member 40 due to vibrations such as those caused by the vehicle V during travel can be suppressed. Therefore, the first insertion port 40X, which exposes a portion of the outer component 30 in the circumferential direction, can be prevented from oriented in an undesirable direction in the circumferential direction. For example, it can be suppressed that the first insertion port 40X is undesirably oriented in a direction opposite to the ground due to vibrations such as those caused by the vehicle V during travel. As a result, for example, the protective performance of the first path limiting member 40, which protects the outer component 30 from flying stones and the like, can be suppressed, and consequently, the durability of the wire harness 10 can be suppressed.

[0089] (2) The first insertion port 40X of the first path limiting member 40 opens in a direction orthogonal to the length direction of the first main body 43 and extends along the entire length of the first main body 43. Therefore, after end processing such as assembling connectors C1, C2, etc., at the ends of the wire member 20 in the length direction, the first path limiting member 40 can be assembled to the outer member 30 through the first insertion port 40X. This allows for the subsequent installation of the first path limiting member 40, thus improving the assembly workability of the wire harness 10.

[0090] (3) The first engaging portion of the first path limiting member 40 is a recess 48 that does not penetrate the first main body portion 43. Furthermore, the second engaging portion of the second path limiting member 50 is a protrusion 68 that engages with the recess 48. According to this structure, by engaging the protrusion 68 with the recess 48, the recesses 48 and the protrusion 68 can engage with each other in the circumferential direction of the wire harness body 11.

[0091] (4) The recess 48 is formed such that it extends along the entire length of the wire harness body 11 and covers the entire length of the connecting portion 47. Similarly, the protrusion 68 is formed such that it extends along the entire length of the wire harness body 11 and covers the entire length of the covering portion 60. With this structure, even if, for example, the connecting portion 47 and the covering portion 60 are slightly misaligned along the length of the wire harness body 11, the recess 48 and the protrusion 68 can be properly engaged in the circumferential direction of the wire harness body 11. This appropriately suppresses circumferential rotation of the first path limiting member 40 relative to the second path limiting member 50.

[0092] (5) The first path limiting member 40 has a first protrusion 45 that protrudes from the inner surfaces of the first end 41 and the second end 42 and can contact the outer surface of the outer member 30. According to this structure, for example, the first protrusion 45 can be used to press the outer member 30 from the outside of the outer member 30. Therefore, the first path limiting member 40 can be appropriately prevented from falling off the outer member 30 through the first insertion port 40X. Furthermore, the first path limiting member 40 has a second protrusion 46 that protrudes from the inner surface of the first main body portion 43 and can contact the outer surface of the outer member 30. According to this structure, both the first protrusion 45 and the second protrusion 46 can contact the outer surface of the outer member 30. Thus, the wobbling of the first path limiting member 40 relative to the outer member 30 can be suppressed.

[0093] (6) Along the length of the harness body 11, the first path limiting member 40 and the second path limiting member 50 are partially overlapped. In this overlapping portion, the recess 48 and the protrusion 68 engage with each other circumferentially in the harness body 11. According to this structure, the relative misalignment of the first path limiting member 40 and the second path limiting member 50 can be suppressed by using the recess 48 provided on the first path limiting member 40 itself and the protrusion 68 provided on the second path limiting member 50 itself. Therefore, compared with the case where the relative misalignment of the first path limiting member 40 and the second path limiting member 50 is suppressed by using additional members, the number of parts can be reduced.

[0094] (7) The covering portion 60 has a covering body portion 61 and a cover portion 62 connected to the covering body portion 61. The covering body portion 61 is part of the second body portion 51 in the second path limiting member 50. The covering portion 60 is formed as an annulus that centrally surrounds the connecting portion 47 and the outer member 30. According to this structure, although the covering portion 60 is set as an annulus that surrounds the connecting portion 47 and the outer member 30, it is divided into a covering body portion 61 and a cover portion 62, so that the second path limiting member 50 including the covering portion 60 can be subsequently installed on the first path limiting member 40 and the outer member 30. As a result, the assembly workability of the wire harness 10 can be further improved.

[0095] (Second Implementation)

[0096] Next, according to Figures 5-7 A second embodiment of the wire harness will be described. Furthermore, in this embodiment, the differences from the first embodiment will be mainly described, and the same reference numerals will be used to label structures identical to those in the first embodiment. Sometimes, part or all of the description may be omitted.

[0097] like Figure 5 As shown, the wiring harness 10A has a fixing member 80, which holds the first path limiting member 40 and is fixed to the body V1 of the vehicle V. The fixing member 80 is, for example, a member that holds and fixes the first path limiting member 40, which is mounted on the exterior member 30, to the mounting surface V2 of the body V1. In this embodiment, the mounting surface V2 is the surface outside the passenger compartment below the floor of the vehicle V, and is the surface facing the ground. The fixing member 80 is, for example, provided in the middle portion of the first path limiting member 40 in the longitudinal direction.

[0098] (Structure of the first path restriction component 40)

[0099] The first path limiting member 40 has a connecting portion 49 that connects to the fixing member 80. The connecting portion 49 is, for example, located in the middle portion along the length direction of the first path limiting member 40. The connecting portion 49 is, for example, located at the center along the length direction of the first path limiting member 40. The connecting portion 49 has a recess 48 located in the first main body portion 43.

[0100] (Structure of fixed component 80)

[0101] The fixing member 80 is made of, for example, metal or resin. In this embodiment, the fixing member 80 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used as the material for the fixing member 80. The fixing member 80 is manufactured, for example, by injection molding.

[0102] The fixing member 80 has, for example, a fixing part 81 that is fixed to the vehicle body V1 and a covering part 90 that covers the outer periphery of the connecting part 49 of the first path limiting member 40. The fixing part 81 is connected to the covering part 90. The covering part 90 surrounds and holds the wiring harness body 11 and the first path limiting member 40.

[0103] like Figure 6 As shown, the fixing member 80 has a fixing part 81 and a covering part 90 arranged in a direction intersecting the length direction of the wire harness body 11. The fixing member 80 is, for example, a single component in which the fixing part 81 and the covering part 90 are formed as one piece.

[0104] The fixing part 81 is formed in a columnar shape, for example. In this embodiment, the fixing part 81 is formed in a quadrangular prism shape. Figure 5 As shown, the fixing part 81 has a fixing hole 82 that extends through the fixing part 81 in a direction orthogonal to the mounting surface V2 (vertical direction in the figure). The fixing part 81 has one or more (two in this embodiment) locking parts 83. The two locking parts 83 are provided on both sides of the fixing hole 82 in the length direction of the wire harness body 11.

[0105] like Figure 7 As shown, the covering portion 90, for example, surrounds the outer periphery of the connecting portion 49. The covering portion 90 is formed, for example, as an annular shape that surrounds the outer periphery of the connecting portion 49 and the outer periphery of the outer fitting member 30 on which the connecting portion 49 is fitted, throughout the entire circumference.

[0106] The covering portion 90, for example, has a second main body portion 91 and a cover portion 92. The second main body portion 91 is connected to the fixing portion 81, for example. For example, the fixing portion 81 is integrally formed at one end of the second main body portion 91 in the circumferential direction. The second main body portion 91, for example, covers a portion of the circumferential direction of the first path limiting member 40 in the outer periphery of the first path limiting member 40. The second main body portion 91, for example, covers a portion of the first main body portion 43 in the outer periphery of the connecting portion 49 in the circumferential direction of the wire harness body 11. The cross-sectional shape of the second main body portion 91 is, for example, formed along the outer surface of the first main body portion 43. The cross-sectional shape of the second main body portion 91 is, for example, formed as an arc or a U-shape.

[0107] like Figure 6 As shown, the second main body 91 has a second insertion port 91X that opens in a direction orthogonal to the length direction of the second main body 91. The second insertion port 91X extends along the entire length of the second main body 91. The opening width of the second insertion port 91X 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 second insertion port 91X in a direction orthogonal to the length direction of the second main body 91.

[0108] The cover portion 92, for example, has a cover body portion 93 that covers a portion of the outer periphery of the connecting portion 49, and an extension portion 94 provided at one circumferential end of the cover body portion 93. The cross-sectional shape of the inner surface of the cover body portion 93 is, for example, formed to correspond to the shape of the outer surface of the outer member 30 or the first path limiting member 40. The cross-sectional shape of the inner surface of the cover body portion 93 is, for example, formed to be an arc shape or an elliptical arc shape. The extension portion 94 has a communicating hole 95 that can communicate with the fixing hole 82 of the fixing portion 81. The extension portion 94 has a claw portion 96 that can engage with the locking portion 83 of the fixing portion 81.

[0109] The cover portion 92 is connected to the second main body portion 91, for example, by means of a hinge portion 97. Specifically, the other end of the second main body portion 91 in the circumferential direction and the other end of the cover body portion 93 in the cover portion 92 in the circumferential direction are connected by means of a hinge portion 97. The second main body portion 91 and the cover portion 92 are integrally formed parts by means of the hinge portion 97.

[0110] The second main body 91 and the cover 92 can rotate relative to each other about the hinge 97. The cover 92 can rotate about the hinge 97 as an axis. Figure 6 The opening position shown is the same as Figure 7 Rotate between the indicated closed positions. For example... Figure 7 As shown, with the cover 92 in the closed position, the claw 96 of the extension 94 hooks onto the locking part 83 of the fixing part 81. The claw 96 and the locking part 83 engage with each other, thus holding the cover 92 in the closed position. In this way, the second main body 91 and the cover 92 are connected. With the second main body 91 and the cover 92 connected, the covering part 90 forms an annulus that centrally surrounds the outer periphery of the outer member 30 and the connecting part 49. That is, the cover 92 is held in the closed position by rotating relative to the second main body 91, thereby surrounding and holding the first path limiting member 40 and the wire harness body 11 together with the second main body 91. Figure 5 As shown, when the cover 92 is in the closed position, the communication hole 95 provided in the extension 94 communicates with the fixing hole 82 of the fixing part 81.

[0111] The fixing member 80 is fixed to the vehicle body V1, for example, with the outer surface of the cover 92 facing the mounting surface V2 of the vehicle body V1. The fixing member 80 is also fixed to the vehicle body V1 with the outer surface of the cover 92 in contact with the mounting surface V2. For example, a fixing piece V3 is provided on the mounting surface V2, extending in a direction perpendicular to the mounting surface V2 and in the ground direction (lower in the figure). The fixing piece V3 passes through the connecting hole 95 and the fixing hole 82 and engages with the edge of the fixing hole 82, thereby fixing the fixing member 80 to the mounting surface V2.

[0112] like Figure 7 As shown, the covering portion 90 has a protrusion 98 serving as a second engaging portion. The covering portion 90 of this embodiment has two protrusions 98. Each protrusion 98 is formed to engage with each recess 48 in the circumferential direction of the wire harness body 11. Each protrusion 98 is, for example, provided on the inner surface of the second body portion 91. Each protrusion 98, for example, protrudes from the inner surface of the second body portion 91 toward the first body portion 43 of the connecting portion 49. Each protrusion 98, for example, is formed to engage with each recess 48. The cross-sectional shape of each protrusion 98 is, for example, a curved shape. The cross-sectional shape of each protrusion 98 is, for example, a semi-circular shape.

[0113] like Figure 6As shown, each protrusion 98 extends, for example, along the length direction of the wire harness body 11. Each protrusion 98 is longer in the length direction of the wire harness body 11 than in the circumferential direction. Each protrusion 98 is formed, for example, such that its dimension along the length direction of the wire harness body 11 is more than twice its dimension along the circumferential direction. Each protrusion 98 extends, for example, along the entire length of the covering portion 90. The protrusions 98 are partially provided in the circumferential direction of the second main body portion 91.

[0114] like Figure 7 As shown, when the protrusion 98 and the recess 48 are engaged, the recess 48 and the protrusion 98 engage with each other in the circumferential direction of the harness body 11. Specifically, when the protrusion 98 and the recess 48 are engaged, the inner surface of the recess 48 and the side surface of the protrusion 98 engage with each other in the circumferential direction of the harness body 11. As a result, the first path limiting member 40 and the fixing member 80 are less likely to move relative to each other in the circumferential direction of the harness body 11. As a result, the first path limiting member 40 can be prevented from rotating circumferentially in the harness body 11 inside the covering portion 90 of the fixing member 80. In addition, when the protrusion 98 and the recess 48 are engaged, the first path limiting member 40 is positioned relative to the covering portion 90 in the circumferential direction of the harness body 11. As a result, the orientation of the first path limiting member 40 relative to the covering portion 90, specifically the orientation of the first insertion port 40X, can be adjusted in the circumferential direction of the harness body 11. In other words, the circumferential position of the first insertion port 40X in the first path limiting member 40 is positioned by the recess 48 and the protrusion 98 that engages with the recess 48. In this embodiment, when the protrusion 98 engages with the recess 48, the circumferential position of the first insertion port 40X in the first path limiting member 40 is set towards the cover portion 92 of the covering portion 90. Therefore, in the state where the connecting portion 49 is engaged with the inner side of the covering portion 90, the first insertion port 40X is positioned towards the mounting surface V2 (see reference 40X). Figure 5 ( ) side, so that the first insertion port 40X faces the side opposite to the ground.

[0115] like Figure 5 As shown, the wiring harness 10A has, for example, a limiting member 71 that restricts the movement of the first path limiting member 40 relative to the outer component 30. The limiting member 71 is provided, for example, at both ends of the first path limiting member 40 in the longitudinal direction.

[0116] Next, the function of this embodiment will be explained.

[0117] By holding the first path limiting member 40, which is mounted on the outer component 30, to the fixing member 80, and fixing the fixing member 80 to the vehicle body V1, the outer component 30 and the first path limiting member 40 can be fixed to the vehicle body V1. At this time, a recess 48 is provided in the first main body portion 43 of the connecting portion 49 of the first path limiting member 40. In addition, a protrusion 98 is provided in the covering portion 90 of the fixing member 80, which engages with the recess 48 in the circumferential direction of the wire harness body 11. By the mutual engagement of these recesses 48 and protrusions 98, the movement of the first path limiting member 40 relative to the fixing member 80 in the circumferential direction of the wire harness body 11 can be suppressed.

[0118] The embodiment described above can achieve the same effect as the first embodiment.

[0119] (Other implementation methods)

[0120] The above embodiments can be implemented with the following modifications. The above embodiments and the following modifications can be combined with each other within the scope of technical inconsistency.

[0121] In the above embodiments, the shape, formation position, and number of the recess 48 as the first engaging portion and the protrusions 68 and 98 as the second engaging portions can be appropriately changed. For example, as long as the first engaging portion and the second engaging portion have a structure that allows them to engage with each other in the circumferential direction of the wire harness body 11, other structures are not particularly limited.

[0122] The connecting portions 47 and 49 may have one or more recesses 48. Similarly, the covering portions 60 and 90 may have one or more protrusions 68 and 98.

[0123] In the first embodiment described above, a protrusion 68 is provided on the inner surface of the covering body portion 61, but this is not a limitation; the protrusion 68 may also be provided on the inner surface of the cover portion 62. In this case, when the protrusion 68 provided on the inner surface of the cover portion 62 engages with the recess 48 of the first path limiting member 40, the circumferential position of, for example, the first insertion port 40X in the first path limiting member 40 is positioned toward the covering body portion 61 side of the covering portion 60. Similarly, the protrusion 98 of the second embodiment described above may also be provided on the inner surface of the cover body portion 93.

[0124] In the above embodiments, the structure is configured such that the first engaging portion is a recess 48, and the second engaging portion is a protrusion 68 or 98, with the first and second engaging portions fitting together in a concave-convex manner, or their concave-convex relationship can be reversed. In this case, for example, the protrusion protruding from the outer surface of the connecting portion 47 as the first engaging portion is provided on the first main body portion 43, and the recessed portion as the second engaging portion, which fits into the protrusion, is provided on the covering portions 60 or 90.

[0125] In the above embodiments, the first engaging portion that engages with the protrusions 68 and 98 is provided as a recess 48 that does not radially penetrate the first path limiting member 40, but this is not a limitation. For example, the first engaging portion may also be provided as a through hole that radially penetrates the first path limiting member 40.

[0126] In the above embodiments, the recess 48 is formed in such a way that it extends along the entire length of the first main body portion 43, but it is not limited to this. For example, the recess 48 may be provided partially along the length of the first main body portion 43. For example, the recess 48 may be provided only in the connecting portions 47 and 49 along the length of the first main body portion 43.

[0127] In the above embodiments, the recess 48 is formed in such a way that it extends along the entire length of the connecting portions 47 and 49, but it is not limited to this. For example, the recess 48 may be provided only partially along the length of the connecting portions 47 and 49.

[0128] In the above embodiments, the recess 48 is formed in a manner that extends continuously along the length direction of the connecting portions 47 and 49, but it is not limited to this. For example, the recess 48 may also be provided in a manner that extends discontinuously along the length direction of the connecting portions 47 and 49. That is, the recess 48 may also be provided partially at predetermined intervals along the length direction of the connecting portions 47 and 49.

[0129] In the above embodiments, the protrusions 68 and 98 are formed in such a way that they extend along the entire length of the covering portions 60 and 90, but this is not a limitation. For example, the protrusions 68 and 98 may be provided partially along the length of the covering portions 60 and 90.

[0130] In the above embodiments, the protrusions 68 and 98 may also be provided in a manner that extends intermittently along the length direction of the covering portions 60 and 90.

[0131] In the above embodiments, the first engaging portion and the second engaging portion are specifically designed as a concave-convex fitting structure, but are not limited thereto. For example, as long as there is a structure that allows the first engaging portion and the second engaging portion to engage in the circumferential direction of the wire harness body 11, both the first engaging portion and the second engaging portion may be designed as convex portions.

[0132] In the first embodiment described above, 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, connecting portions 47 with recesses 48 may also be provided at both ends of the first path limiting member 40 in the longitudinal direction.

[0133] The structure of the first path limiting member 40 in each of the above embodiments can be appropriately modified. For example, as long as the first path limiting member 40 has a first main body portion 43 and a first insertion port 40X, and has a structure that can be assembled to the outer periphery of the outer component 30, other structures are not particularly limited.

[0134] In the above embodiments, each second protrusion 46 is disposed on the inner surface of the portion of the first main body 43 in the circumferential direction where the recess 48 is formed, but this is not a limitation. For example, the second protrusion 46 and the recess 48 may be disposed in a staggered position in the circumferential direction of the first main body 43.

[0135] Alternatively, each second protrusion 46 may be provided locally along the length direction of the first path limiting member 40.

[0136] Alternatively, at least one of the two second protrusions 46 can be omitted.

[0137] Alternatively, each of the first protrusions 45 may be positioned in the circumferential direction of the first path limiting member 40 at a position further away from the first insertion port 40X than the top ends 41A and 42A.

[0138] Each first protrusion 45 may also be provided locally along the length direction of the first path limiting member 40.

[0139] Alternatively, at least one of the two first protrusions 45 can be omitted.

[0140] It can also be configured such that the radial thickness of the first main body 43 varies in the circumferential direction.

[0141] The first path limiting member 40 is not limited to a member installed under the floor of the vehicle V. The first path limiting member 40 can be any part that extends in a straight line along the path of the wiring harness body 11, for example, it can also be a member installed inside the carriage of the vehicle V.

[0142] The structure of the second path limiting member 50 in the first embodiment described above can be appropriately modified. For example, as long as the second path limiting member 50 has the following structure: having a second engaging portion that can engage with the first engaging portion, and having a covering portion 60 that covers the connecting portion 47, other structures are not particularly limited.

[0143] In the second path limiting member 50, the second main body 51 and the cover 62 are formed as one piece, but this is not a limitation; the second main body 51 and the cover 62 can also be separated. That is, the second main body 51 and the cover 62 can also be separate parts.

[0144] The cover 62 in the second path limiting member 50 can also be omitted.

[0145] The bending shape in the second main body 51 can be appropriately changed. For example, the bending shape in the second main body 51 can also be changed to a straight-line extension shape.

[0146] In the second path limiting member 50, a cover portion connected to the second main body 51 other than the covering main body 61 may also be provided.

[0147] At least one of the limiting members 71 and 72 in the first embodiment described above may also be omitted.

[0148] In the first embodiment described above, 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 only limitation; they may also be of equal or less hardness than 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.

[0149] The structure of the fixing member 80 in the second embodiment described above can be appropriately modified. For example, as long as the fixing member 80 has the following structure: having a second engaging portion that can engage with the first engaging portion, and having a covering portion 90 that covers the connecting portion 49, other structures are not particularly limited.

[0150] In the covering portion 90, the second main body portion 91 and the cover portion 92 are formed as one piece, but this is not a limitation; the second main body portion 91 and the cover portion 92 can also be separated. Furthermore, even when the second main body portion 91 and the cover portion 92 are separate components, it is still necessary for the cover portion 92 to be able to connect to the second main body portion 91, and in the state of being connected to the second main body portion 91, to be able to surround and retain the first path limiting member 40 together with the second main body portion 91.

[0151] The covering portion 90 is configured to have a second main body portion 91 and a cover portion 92, and can be subsequently assembled to the first path limiting member 40, but is not limited thereto. For example, the covering portion 90 may be configured to be immovable when the cover portion 92 is closed. In this case, the fixing member 80 cannot be subsequently assembled to the first path limiting member 40; specifically, it cannot be assembled from a direction orthogonal to the length direction of the first path limiting member 40, but rather the first path limiting member 40 must be assembled to the fixing member 80 by passing through it in the length direction.

[0152] The structure of the fixing part 81 can be appropriately modified. For example, the fixing member 80 in the second embodiment described above is fixed to the vehicle body V1 by a fixing piece V3 extending from the mounting surface V2 toward the ground, but it is not limited to this and can also be fixed by other structures. For example, the fixing member 80 can also be fixed to the mounting surface V2 by means of other mounting brackets. For example, the fixing member 80 can also be configured to have a mounting part that is mounted to a mounting hole formed in the mounting surface V2, and the fixing member 80 is fixed to the mounting surface V2 by fitting the mounting part into the mounting hole.

[0153] The fixing member 80 can also be fixed to the vehicle body V1 with the outer surface of the cover portion 92 of the covering portion 90 facing the mounting surface V2, but it is not limited to this. For example, the fixing member 80 can also be fixed to the vehicle body V1 with the outer surface of the second main body portion 91 of the covering portion 90 facing the mounting surface V2.

[0154] In the second embodiment described above, two or more fixing members 80 may also be provided in the length direction of the first path limiting member 40.

[0155] In the first embodiment described above, the assembly member having the covering portion 60 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 60.

[0156] In the second embodiment described above, the assembly member having the covering portion 90 is specifically embodied as the fixing member 80, but it is not limited to this. For example, the assembly member may also be embodied as a structure having only the covering portion 90.

[0157] At least one of the two limiting members 71 in the second embodiment described above may also be omitted.

[0158] The outer component 30 may be, for example, an outer component having a metal layer containing a metallic material disposed on the outer surface of a resin bellows.

[0159] The outer component 30 is not limited to a bellows; for example, it can also be an outer component without the annular protrusion 31 and the annular recess 32.

[0160] The outer component 30 may also be an outer component having a slit extending in the length direction of the outer component 30.

[0161] 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.

[0162] 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 can also be embodied as a metal foil.

[0163] The braided component 25 in the wire component 20 can also be omitted.

[0164] 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.

[0165] 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.

[0166] The multiple on-board devices electrically connected by wiring harness 10 and 10A are specifically embodied as inverter M1 and high-voltage battery M2, but are not limited thereto. The multiple on-board devices electrically connected by wiring harness 10 and 10A are not specifically limited as long as they are electrical devices mounted on vehicle V.

[0167] 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.
