[0021] [Explanation of Embodiments of the Present Disclosure]

[0022] First, an embodiment of the present disclosure will be explained.

[0023] [1] A wire harness of the present disclosure has: a wire harness main body having an electric wire member and an outer covering member that covers an outer periphery of the electric wire member; a path restricting member that is fitted to an outer periphery of the outer covering member and restricts a path of the wire harness main body; and a fitting member that is fitted to an outer periphery of a portion of the path restricting member in a length direction, the path restricting member having: a first main body portion that covers a portion of the outer periphery of the outer covering member; and an insertion opening that is opened in a direction orthogonal to the length direction of the first main body portion and extends over an entire length of the length direction of the first main body portion, the path restricting member having a connection portion that is connected to the fitting member, the fitting member having a covering portion that covers an outer periphery of the connection portion, the covering portion having a restricting wall that is engageable with an end surface of the length direction of the path restricting member in the length direction of the wire harness main body.

[0024] According to this structure, the connection portion of the path restricting member and the covering portion of the fitting member are disposed in overlap in the length direction of the wire harness main body. At this time, the restricting wall that is engageable with the end surface of the length direction of the path restricting member is provided to the covering portion. Therefore, by engaging the end surface of the length direction of the path restricting member with the restricting wall, positioning of the path restricting member with respect to the fitting member can be easily performed when the path restricting member is fitted to the fitting member. Thus, workability when the path restricting member is fitted to the fitting member can be improved. Further, assembly workability of the wire harness can be improved.

[0025] [2] Preferably, the covering portion is formed in a ring shape that surrounds the outer periphery of the connecting portion and the outer periphery of the portion of the outer member to which the connecting portion is fitted, the covering portion has a second body portion that covers a part of the outer periphery of the first body portion, and a cover portion that is connected to the second body portion.

[0026] According to this structure, although the covering portion is provided in a ring shape, the covering portion is divided into the second body portion and the cover portion, so that the fitting member including the covering portion can be attached to the path restricting member and the outer member. Thus, the assembly workability of the wire harness can be improved.

[0027] [3] Preferably, the restricting wall has a body-side restricting wall that protrudes from the inner surface of the second body portion toward the radially inner side of the covering portion, and a cover-side restricting wall that protrudes from the inner surface of the cover portion toward the radially inner side of the covering portion.

[0028] According to this structure, in the case where the path restricting member is inserted into the second body portion first, the lengthwise end surface of the path restricting member can be engaged with the body-side restricting wall. Also, in the case where the cover portion is inserted into the path restricting member first, the lengthwise end surface of the path restricting member can be engaged with the cover-side restricting wall. Thus, the positioning of the path restricting member with respect to the fitting member can be easily performed regardless of which one of the second body portion and the cover portion the path restricting member is inserted into first.

[0029] [4] Preferably, the second body portion has a first receiving opening that opens in a direction orthogonal to the lengthwise direction of the second body portion, the body-side restricting wall is formed so as to extend over the entire circumference of the second body portion in the circumferential direction of the covering portion, the body-side restricting wall has a second receiving opening that opens in a direction orthogonal to the lengthwise direction of the second body portion and that communicates with the first receiving opening, and the opening width of the second receiving opening is smaller than the opening width of the first receiving opening, and the opening width of the second receiving opening is smaller than the outer diameter of the path restricting member.

[0030] According to this structure, the opening width of the second receiving opening provided in the body-side restricting wall is formed to be smaller than the outer diameter of the path restricting member. Thus, in the case where the path restricting member is inserted into the covering portion, the lengthwise end surface of the path restricting member can be properly engaged with the body-side restricting wall. Thus, the positioning of the path restricting member with respect to the fitting member can be properly performed.

[0031] [5] Preferably, the path restricting member has a first end portion and a second end portion, the first end portion and the second end portion being both end portions of the first body portion in the circumferential direction, the insertion port being formed, the cover portion has a protruding portion protruding from an inner surface of the cover portion toward the insertion port, the protruding portion being contactable with at least one of the first end portion and the second end portion in the circumferential direction of the path restricting member.

[0032] According to this structure, the protruding portion of the cover portion is contactable with at least one of the first end portion and the second end portion forming the insertion port in the circumferential direction of the path restricting member. Therefore, the protruding portion and the first end portion or the second end portion are engaged in the circumferential direction of the path restricting member. Thus, the circumferential rotation of the path restricting member relative to the cover portion can be appropriately suppressed.

[0033] [6] Preferably, the outer member is a bellows having a bellows structure in which annular convex portions and annular concave portions are alternately connected in the length direction of the outer member, the protruding portion has a protruding part that enters the annular concave portion.

[0034] According to this structure, the protruding portion has a protruding part that enters the annular concave portion of the bellows. Therefore, the movement of the bellows relative to the fitting member in the length direction of the bellows can be suppressed.

[0035] [7] Preferably, an interference amount is provided between the outer periphery of the path restricting member and the inner periphery of the cover portion.

[0036] According to this structure, the path restricting member and the inner periphery of the cover portion are fitted with an interference amount. That is, when the path restricting member is fitted to the inside of the cover portion, the outer peripheral surface of the path restricting member and the inner peripheral surface of the cover portion are in contact with an interference amount. Thus, the path restricting member fitted to the inside of the cover portion is held in a state in which the inner surface of the cover portion presses the path restricting member toward the radially inner side of the cover portion. Therefore, the path restricting member can be suppressed from wobbling in the inside of the cover portion. In addition, the relative movement of the path restricting member relative to the cover portion in the length direction of the wire harness body can be appropriately suppressed. As a result, the misalignment of the path restricting member relative to the cover portion in the length direction of the wire harness body can be appropriately suppressed, and the path restricting member can be appropriately suppressed from coming off the cover portion.

[0037] [8] Preferably, when the path restricting member is provided as a first path restricting member, the fitting member is a second path restricting member having a path restricting portion that fits to the outer periphery of the outer member and restricts the path of the wire harness body, the connecting portion is provided to an end portion in the length direction of the first path restricting member, the second path restricting member is continuously formed with the covering portion and the path restricting portion in the length direction of the wire harness body, the covering portion is provided to an end portion in the length direction of the second path restricting member, and the restricting wall is provided to an end portion in the length direction of the covering portion that is connected to the path restricting portion.

[0038] According to this structure, the restricting wall is provided to an end portion in the length direction of the covering portion that is connected to the path restricting portion. By the restricting wall, the amount of insertion of the first path restricting member in the length direction of the wire harness body relative to the second path restricting member can be restricted. Therefore, the insertion of the first path restricting member into the path restricting portion of the second path restricting member in the length direction of the wire harness body can be suppressed.

[0039] [9] Preferably, the first path restricting member restricts the path of a straight portion, the path of the straight portion being a portion of the path of the wire harness body that is straight, and the second path restricting member restricts the path of a bent portion, the path of the bent portion being a portion of the path of the wire harness body that is bent.

[0040] According to this structure, the path of the straight portion is restricted by the first path restricting member, and the path of the bent portion is restricted by the second path restricting member. Thereby, the path of the straight portion and the path of the bent portion can be suppressed from deviating from the desired paths, respectively.

[0041] [Details of the embodiments of the present disclosure]

[0042] A specific example of a wire harness of the present disclosure will be described below with reference to the drawings. In the drawings, a part of a structure is sometimes enlarged or simplified for the sake of convenience in explanation. In addition, the dimensional ratios of the parts are sometimes different in the drawings. In the present specification, "orthogonal", "parallel", and "full length" include not only cases of being strictly orthogonal, parallel, and full length, but also cases of being approximately orthogonal, parallel, and full length, within a range in which the effects in the present embodiment function. In the present specification, the term "equal" includes not only cases of being exactly equal, but also cases in which the objects to be compared have some difference from each other due to dimensional tolerances and the like. In addition, the "cylindrical" used in the explanation of the present specification includes not only a shape in which a peripheral wall is continuously formed all around in the circumferential direction, but also a shape in which a plurality of members are combined to form a cylindrical shape, or a shape in which a notch or the like is provided in the circumferential direction, such as a C-shaped. Further, the shape of the "cylindrical" includes a circular shape, an elliptical shape, and a polygonal shape with sharp corners or rounded corners, but is not limited thereto. In addition, the term "annular" used in the explanation of the present specification sometimes refers to an arbitrary structure that forms a ring, or a continuous shape without an end, and a structure that is generally annular, such as a C-shaped, with a gap. Further, the shape of the "annular" includes a circular shape, an elliptical shape, and a polygonal shape with sharp corners or rounded corners, but is not limited thereto. In addition, "facing" in the present specification means a position in which surfaces or members face each other, and includes not only a position in which they completely face each other, but also a position in which they partially face each other. In addition, "facing" in the present specification includes both a case in which a different member is interposed between the two parts, and a case in which nothing is interposed between the two parts. Further, the present application is not limited to these examples, but is shown by the claims, and includes all modifications within the meaning and range equivalent to the claims.

[0043] (Overall structure of wire harness 10)

[0044] Figure 1 The wire harness 10 illustrated is mounted on a vehicle V such as a hybrid vehicle, an electric vehicle, or the like. The wire harness 10 electrically connects two or more vehicle-mounted devices to each other. The vehicle-mounted device is an electrical device mounted on the vehicle V. The wire harness 10, for example, electrically connects an inverter M1 provided at a front portion of the vehicle V and a high-voltage battery M2 provided at a rear portion of the vehicle V further than the inverter M1. The wire harness 10 is formed in a long size, for example, in a manner extending in a front-rear direction of the vehicle V. The wire harness 10 is laid out in the vehicle V, for example, in a manner that a middle portion in a length direction of the wire harness 10 passes outside the vehicle cabin, under a floor of the vehicle V, or the like.

[0045] The inverter M1 is connected to an electric motor for driving wheels, which is not illustrated, that is a power source for running the vehicle, for example. The inverter M1 generates alternating current from direct current of the high-voltage battery M2, and supplies the alternating current to the electric motor. The high-voltage battery M2 is a battery capable of supplying a voltage of several hundred volts, for example.

[0046] 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.

[0047] like Figure 2 and Figure 3 As shown, the wire harness 10 has a first path limiting member 40 mounted on the outer periphery of the outer component 30 and a second path limiting member 50 mounted on the outer periphery of the outer component 30. The first path limiting member 40 and the second path limiting member 50 limit the routing path of the wire harness body 11. Furthermore, in Figure 1 The illustrations of the first path limiting member 40 and the second path limiting member 50 are omitted.

[0048] (Structure of electrical component 20)

[0049] 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.

[0050] like Figure 4 Each wire 21 is a covered wire having a core wire 22 and an insulating covering 23. The core wire 22 is conductive, and the insulating covering 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.

[0051] 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.

[0052] 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.

[0053] The cross-sectional shape of each wire 21, which is the shape of the cross section cut by a plane orthogonal to the length direction of each wire 21, can be any shape. For example, the cross-sectional shape of each wire 21 can be formed as a circle, a semi-circle, a polygon, a square, a flat shape, etc. In this embodiment, the cross-sectional shape of each wire 21 is formed as a circle.

[0054] 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.

[0055] (Structure of external component 30)

[0056] like Figure 3 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 on the entire circumference of the outer casing 30. For example, the outer casing 30 is sealed on the entire circumference of the outer casing 30. For example, the outer casing 30 has the function of protecting the wire component 20 from flying objects and water droplets.

[0057] The outer component 30 is flexible, for example, and can be easily bent. Examples of flexible outer components 30 include resin bellows and rubber waterproof caps. In this embodiment, the outer component 30 is a resin bellows with a corrugated structure in which annular protrusions 31 and annular recesses 32 are alternately connected along the length of the outer component 30. Each of the annular protrusions 31 and annular recesses 32 forms an annulus around the circumference of the outer component 30. As a material for the outer component 30, synthetic resins such as polyolefins, polyamides, polyesters, and ABS resins can be used. Furthermore, in Figure 1 and Figure 2 In order to simplify the accompanying drawings, the external component 30 is shown in a simplified manner.

[0058] (Structure of the first path limiting member 40 and the second path limiting member 50)

[0059] like Figure 2As shown, the first path limiting member 40 and the second path limiting member 50 each hold the outer member 30. The first path limiting member 40 and the second path limiting member 50 are, for example, more rigid than the outer member 30. The first path limiting member 40 and the second path limiting member 50 each have a rigidity that makes them less prone to bending in a direction orthogonal to the length direction of the wire harness body 11 compared to the outer member 30. Therefore, the first path limiting member 40 and the second path limiting member 50 each restrict the path of the wire harness body 11. For example, the first path limiting member 40 and the second path limiting member 50 each assist the outer member 30 so that the wire harness body 11 does not deviate from the desired path due to its own weight or other deflections. The outer member 30 is, for example, less prone to bending than when the first path limiting member 40 and the second path limiting member 50 are not attached.

[0060] The first path limiting member 40 is partially provided along the length of the wire harness body 11. For example, the first path limiting member 40 is fitted to the outer periphery of the outer member 30 in a straight portion 11A, which is a straight section in the path of the wire harness body 11. The first path limiting member 40 restricts the path of the wire harness body 11 in the straight portion 11A. Here, the straight portion 11A is the portion of the wire harness body 11 whose path extends straight in one direction. Furthermore, one or more first path limiting members 40 are provided according to the path of the wire harness body 11.

[0061] The second path limiting member 50 is partially provided along the length of the wire harness body 11. For example, the second path limiting member 50 is fitted to the outer periphery of the outer member 30 at a bend 11B, which is a portion of the wire harness body 11 that bends in its path. The second path limiting member 50 restricts the path of the wire harness body 11 within the bend 11B. Here, the bend 11B is a portion of the wire harness body 11 where the path bends in a two-dimensional or three-dimensional shape. Furthermore, one or more second path limiting members 50 are provided depending on the path of the wire harness body 11.

[0062] (Structure of the first path restriction component 40)

[0063] like Figure 4 As shown, the first path limiting member 40 partially covers the circumferential periphery of the outer member 30. The first path limiting member 40 is formed in a cylindrical shape that partially covers the circumferential periphery of the outer member 30. The cross-sectional shape of the first path limiting member 40 is generally C-shaped. The first path limiting member 40 covers, for example, an area larger than half the circumference of the outer member 30. The cross-sectional shape of the first path limiting member 40 is, for example, the same along its entire length. Figure 2 As shown, the first path limiting member 40 extends, for example, along the path of the straight portion 11A, and is formed in a shape that extends in a straight line in one direction.

[0064] The first path limiting member 40 is made of, for example, metal or resin. In this embodiment, the first path limiting member 40 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used as the material for the first path limiting member 40. The first path limiting member 40 can be manufactured, for example, by known manufacturing methods such as extrusion molding or injection molding.

[0065] like Figure 3 As shown, the first path limiting member 40 has a first main body portion 41 that partially covers the outer periphery of the outer component 30, and an insertion port 42 that opens in a direction orthogonal to the length direction of the first main body portion 41. The first path limiting member 40 has a first end portion 43 and a second end portion 44, which are the two ends of the first main body portion 41 in the circumferential direction, forming the insertion port 42.

[0066] like Figure 4 As shown, the first main body portion 41 constitutes the main part of the first path limiting member 40. The radial thickness of the first main body portion 41 is, for example, the same in the circumferential direction of the first path limiting member 40. The cross-sectional shape of the first main body portion 41 is, for example, formed along the outer surface of the outer member 30. The cross-sectional shape of the first main body portion 41 is, for example, formed as an arc.

[0067] The first end 43 and the second end 44 are disposed on opposite sides of each other in the circumferential direction of the first main body 41. The first end 43 and the second end 44 are disposed separately from each other in the circumferential direction of the first main body 41 through the insertion port 42. In other words, in the circumferential direction of the first path limiting member 40, the gap between the first end 43 and the second end 44 constitutes the insertion port 42. Thus, the first path limiting member 40 is formed in a C-shape with the insertion port 42 partially present in the circumferential direction of the first main body 41.

[0068] The opening width of the insertion port 42, that is, the shortest distance between the first end 43 and the second end 44, is, for example, less than the outer diameter of the outer component 30. Figure 3 The insertion port 42 extends along the entire length of the first main body portion 41. That is, the insertion port 42 is formed such that it opens in a direction orthogonal to the length direction of the first main body portion 41 and opens at both ends of the length direction of the first main body portion 41.

[0069] By inserting the outer component 30 into the insertion port 42 in a direction orthogonal to the length direction of the first path limiting member 40, the first path limiting member 40 elastically deforms, increasing the opening width of the insertion port 42. When the outer component 30 is inserted into the interior of the first path limiting member 40, the first path limiting member 40 elastically returns to its original shape. Thus, the opening width of the insertion port 42 becomes smaller than the outer diameter of the outer component 30, and therefore the first path limiting member 40 is fitted onto the outer periphery of the outer component 30.

[0070] Furthermore, when the outer component 30 is inserted into the first path limiting member 40, the opening width of the insertion port 42 may not return to its original width, i.e., the width when the outer component 30 is not inserted. Specifically, the elastic deformation of the first main body 41 that would return to its original shape is hindered by the outer component 30, so the opening width of the insertion port 42 may sometimes become slightly larger than the original width. In addition, when the outer component 30 is inserted into the first path limiting member 40, due to the pressing of the first path limiting member 40, the outer component 30 becomes flexed, so the opening width of the insertion port 42 may sometimes return to its original width. That is, the opening width of the insertion port 42 when the outer component 30 is inserted into the first path limiting member 40 becomes based on the rigidity, flexibility, etc. of the outer component 30 and the first path limiting member 40.

[0071] like Figure 4 As shown, the first end 43 has a tip 43A. The second end 44 has a tip 44A. Tips 43A and 44A form an insertion port 42. Tips 43A and 44A are formed in a curved shape when viewed from the length direction of the first path limiting member 40. That is, the cross-sectional shape of tips 43A and 44A is formed in a curved shape.

[0072] The first path limiting member 40 has, for example, protrusions 45 extending from the inner surfaces of the first end 43 and the second end 44. Each protrusion 45 protrudes toward the outer member 30 inserted into the first path limiting member 40 and can contact the outer surface of the outer member 30. Each protrusion 45, for example, contacts the outer surface of the annular protrusion 31 of the outer member 30. Two protrusions 45, for example, protrude from the inner surfaces of the top ends 43A and 44A. The cross-sectional shape of each protrusion 45 is, for example, formed as a curved shape. In this embodiment, the cross-sectional shape of each protrusion 45 is formed as a semi-circular shape. Each protrusion 45 extends along the entire length of the first path limiting member 40.

[0073] The projections 45 press the outer member 30, for example, from the outside of the outer member 30. The outer member 30 is elastically sandwiched by the two projections 45 and the first body portion 41. Thus, the connection of the first path restriction member 40 to the outer member 30 becomes firm. Therefore, the first path restriction member 40 fitted to the outer periphery of the outer member 30 can be inhibited from moving in the length direction of the outer member 30.

[0074] As shown in FIG. 1, the first path restriction member 40 is fitted to the outer periphery of the outer member 30 in the bent portion 11B. The first path restriction member 40 is bent along the shape of the bent portion 11B. The first path restriction member 40 is, for example, metal or resin. The first path restriction member 40 of the present embodiment is resin. As the material of the first path restriction member 40, for example, a synthetic resin such as polypropylene, polyamide, polyacetal, or the like can be used. The first path restriction member 40 can be manufactured, for example, by a known manufacturing method such as injection molding. Figure 3 As shown in FIG. 1, the first path restriction member 40 has a connection portion 47 that is connected to the second path restriction member 50. The connection portion 47 is provided, for example, at one end portion in the length direction of the first path restriction member 40. The connection portion 47 has an end surface 47A in the length direction of the first path restriction member 40.

[0075] (Structure of the second path restriction member 50)

[0076] As shown in FIG. 1, the second path restriction member 50 is fitted to the outer periphery of the outer member 30 in the bent portion 11B. The second path restriction member 50 is bent along the shape of the bent portion 11B. The second path restriction member 50 is, for example, metal or resin. The second path restriction member 50 of the present embodiment is resin. As the material of the second path restriction member 50, for example, a synthetic resin such as polypropylene, polyamide, polyacetal, or the like can be used. The second path restriction member 50 can be manufactured, for example, by a known manufacturing method such as injection molding. Figure 2 As shown in FIG. 1, the second path restriction member 50 has a connection portion 47 that is connected to the second path restriction member 50. The connection portion 47 is provided, for example, at one end portion in the length direction of the first path restriction member 40. The connection portion 47 has an end surface 47A in the length direction of the first path restriction member 40.

[0077] The second path restriction member 50 has a covering portion 51 that covers a part of the length direction of the first path restriction member 40, and a path restriction portion 70 that is fitted to the outer periphery of the outer member 30. In the second path restriction member 50, for example, the covering portion 51 and the path restriction portion 70 are continuously formed in the length direction of the wire harness body 11. The second path restriction member 50 is, for example, a single member in which the covering portion 51 and the path restriction portion 70 are formed in one body. The covering portion 51 is provided, for example, at one end portion in the length direction of the second path restriction member 50. The covering portion 51 has a second body portion 52 and a cover portion 56 that is connected to the second body portion 52. The path restriction portion 70 has a third body portion 71. The third body portion 71 is continuously formed in one body with the second body portion 52.

[0078] (Structure of the covering portion 51)

[0079] As shown in FIG. 1, the covering portion 51 is provided, for example, so as to overlap the connection portion 47 in the radial direction of the outer member 30. That is, in the wire harness 10, one end portion in the length direction of the first path restriction member 40 and one end portion in the length direction of the second path restriction member 50 are provided so as to overlap each other in the length direction of the wire harness body 11. Figure 2

[0080] ​The covering portion 51, for example, surrounds the outer periphery of the connecting portion 47 of the first path limiting member 40. The covering portion 51 is formed, for example, annular, surrounding the outer periphery of the connecting portion 47 and the outer periphery of the outer member 30 in the portion where the connecting portion 47 is assembled. The covering portion 51 extends along the path of the straight portion 11A, for example, and is formed in a shape that extends in a straight line in one direction.

[0081] like Figure 4 As shown, the second main body portion 52, for example, partially covers the circumferential portion of the outer periphery of the outer member 30. The second main body portion 52, for example, partially covers the circumferential portion of the outer periphery of the first path limiting member 40. The second main body portion 52 is formed in a cylindrical shape that partially covers the circumferential portion of the first path limiting member 40. The second main body portion 52, for example, covers the outer periphery of the first main body portion 41 within the first path limiting member 40. The second main body portion 52, for example, covers an area larger than half the outer periphery of the first main body portion 41. The cross-sectional shape of the inner surface of the second main body portion 52 is, for example, formed to correspond to the shape of the outer surface of the first main body portion 41. The cross-sectional shape of the inner surface of the second main body portion 52 is, for example, formed to be a curved shape. The cross-sectional shape of the inner surface of the second main body portion 52 is generally U-shaped.

[0082] The second main body portion 52 has a third end portion 53 and a fourth end portion 54, which are the two circumferential ends of the second main body portion 52. The second main body portion 52 has a first receiving opening 55 formed by the third end portion 53 and the fourth end portion 54. The first receiving opening 55 is an opening between the third end portion 53 and the fourth end portion 54. Figure 3 As shown, the first receiving opening 55 opens in a direction orthogonal to the length direction of the second main body 52. ​​The first receiving opening 55 extends along the entire length of the second main body 52. ​​The opening width of the first receiving opening 55, that is, the shortest distance between the third end 53 and the fourth end 54, is, for example, equal to or larger than the outer diameter of the first path limiting member 40. The outer fitting member 30 and the first path limiting member 40 are inserted into the first receiving opening 55 in a direction orthogonal to the length direction of the second path limiting member 50.

[0083] The cover portion 56 is integrally formed with the second main body portion 52, for example. The cross-sectional shape of the inner surface of the cover portion 56 is, for example, formed to correspond to the shape of the outer surface of the outer component 30. The cross-sectional shape of the inner surface of the cover portion 56 is, for example, formed to correspond to the shape of the outer surface of the first path limiting member 40. The cross-sectional shape of the inner surface of the cover portion 56 is, for example, formed into an elliptical arc or an oblong arc. The cover portion 56 is, for example, formed into a generally semi-elliptical cylinder. Here, "oblong" in this specification refers to a shape composed of two parallel lines of approximately equal length and two semicircles.

[0084] The cover 56 covers the first receiving opening 55 of the second main body 52. ​​For example, the cover 56 covers the first receiving opening 55 only in the covering portion 51 in the longitudinal direction of the second path limiting member 50. In other words, the cover 56 is only provided in the covering portion 51 in the second path limiting member 50, and not in the path limiting portion 70.

[0085] The covering portion 51, for example, has a hinge portion 57 that connects the second main body portion 52 and the cover portion 56. The hinge portion 57 connects one circumferential end of the second main body portion 52 (here, the third end portion 53) and one circumferential end of the cover portion 56. One or more (two in this embodiment) locking portions 58 are provided at the other circumferential end of the second main body portion 52 (here, the fourth end portion 54). One or more (two in this embodiment) claw portions 59 are provided at the other circumferential end of the cover portion 56.

[0086] The second main body 52 and the cover 56 can rotate relative to each other about the hinge 57. The cover 56 can rotate about the hinge 57 as an axis. Figure 3 The opening position shown is the same as Figure 2 Rotate between the indicated closed positions. For example... Figure 4 As shown, with the cover 56 in the closed position, the claw 59 hooks onto the locking part 58. Thus, the cover 56 remains in the closed position. In this way, the second main body 52 and the cover 56 are connected to each other. With the second main body 52 and the cover 56 connected, the covering part 51 forms an annular ring that centrally surrounds the outer periphery of the outer component 30 and the connecting part 47. In the closed position, the cover 56 covers the first receiving opening 55 of the second main body 52. ​​For example, in the closed position, the cover 56 covers the insertion opening 42 in the connecting part 47.

[0087] In this embodiment, when the cover 56 is in the closed position, the inner surface of the cover 56 does not contact the outer surface of the first path limiting member 40. That is, a gap is created between the inner surface of the cover 56 and the outer surface of the first path limiting member 40. This gap, for example, is created along the entire length of the covering portion 51 in the longitudinal direction.

[0088] like Figure 3As shown, the covering portion 51, for example, has a limiting wall 60, which can engage with the end face 47A of the first path limiting member 40 in the longitudinal direction along the length of the wire harness body 11. The limiting wall 60, for example, protrudes radially inward from the inner surface of the covering portion 51. The limiting wall 60, for example, extends circumferentially along the covering portion 51. The limiting wall 60, for example, extends throughout the entire circumference of the covering portion 51. The limiting wall 60 is provided at one end of the covering portion 51 in the longitudinal direction.

[0089] The limiting wall 60 has, for example, a body-side limiting wall 61 formed on the inner surface of the second body portion 52 and a cover-side limiting wall 62 formed on the inner surface of the cover portion 56. The body-side limiting wall 61 and the cover-side limiting wall 62 are provided at the same position relative to each other, for example, in the length direction of the wire harness body 11.

[0090] like Figure 5 As shown, the main body side limiting wall 61 protrudes radially inward from the inner surface of the second main body portion 52. The main body side limiting wall 61 extends, for example, throughout the entire circumference of the second main body portion 52 in the circumferential direction of the covering portion 51. The cross-sectional shape of the inner surface of the main body side limiting wall 61 is formed to be the same as the cross-sectional shape of the inner surface of the second main body portion 52. In this embodiment, the cross-sectional shape of the inner surface of the main body side limiting wall 61 is formed in a U-shape. The cross-sectional shape of the inner surface of the main body side limiting wall 61 is, for example, formed to be one size smaller than the cross-sectional shape of the inner surface of the second main body portion 52. Furthermore, in Figure 5 The diagram of the wire component 20 is omitted.

[0091] The main body side limiting wall 61 has a second receiving opening 63 that opens in a direction orthogonal to the length direction of the second main body portion 52. The second receiving opening 63 communicates with the first receiving opening 55. The first receiving opening 55 and the second receiving opening 63 extend along the entire length of the second main body portion 52. The opening width of the second receiving opening 63 is smaller than the opening width of the first receiving opening 55. The opening width of the second receiving opening 63 is, for example, smaller than the outer diameter of the first path limiting member 40.

[0092] like Figure 3 As shown, the main body side limiting wall 61 is provided, for example, at one of the two ends of the second main body portion 52 in the longitudinal direction, at the end connected to the third main body portion 71. The main body side limiting wall 61 extends, for example, along the longitudinal direction of the wire harness body 11. The main body side limiting wall 61 extends, for example, from the end of the second main body portion 52 throughout the entire longitudinal direction of the third main body portion 71. For example, a step is formed at the boundary between the inner surface of the second main body portion 52 and the inner surface of the third main body portion 71 due to the main body side limiting wall 61.

[0093] like Figure 6As shown, the end face 61A of the main body side limiting wall 61 in the longitudinal direction is opposite to the first main body portion 41 of the first path limiting member 40 in the longitudinal direction of the wire harness main body 11, and can contact the first main body portion 41. The end face 61A of the main body side limiting wall 61 in the longitudinal direction is opposite to the end face 47A of the first path limiting member 40 in the longitudinal direction of the wire harness main body 11, and can contact the end face 47A.

[0094] like Figure 5 As shown, the cover-side limiting wall 62 protrudes radially inward from the inner surface of the cover portion 56. The cover-side limiting wall 62 extends, for example, throughout the entire circumference of the cover portion 56 in the circumferential direction of the covering portion 51. The cross-sectional shape of the inner surface of the cover-side limiting wall 62 is, for example, formed to correspond to the shape of the outer surface of the first path limiting member 40. The cross-sectional shape of the inner surface of the cover-side limiting wall 62 is, for example, formed in a circular arc shape or an elliptical arc shape. In this embodiment, the cross-sectional shape of the inner surface of the cover-side limiting wall 62 is formed in a semi-elliptical arc shape.

[0095] Side limiting wall 62, for example, in wire harness body 11 (see reference) Figure 3 It is positioned along the length of the first path limiting member 40 opposite to the first end 43 and the second end 44, and can contact those first ends 43 and the second end 44.

[0096] like Figure 3 As shown, the limiting wall 60, which is composed of the main body-side limiting wall 61 and the cover-side limiting wall 62, restricts the movement of the first path limiting member 40 in the length direction of the wire harness body 11 by contacting the end face 47A of the first path limiting member 40 in the length direction. For example, the limiting wall 60 restricts the movement of the first path limiting member 40 in such a way that the first path limiting member 40 is not inserted into the path limiting part 70.

[0097] like Figure 4 As shown, the covering portion 51 has, for example, a protrusion 65. The protrusion 65 protrudes from the inner surface of the covering portion 51 toward the insertion port 42 of the first path limiting member 40 inserted into the interior of the covering portion 51. The protrusion 65 protrudes in such a manner that it is disposed inside the insertion port 42. The protrusion 65 can contact the first end portion 43 and the second end portion 44 in the circumferential direction of the first path limiting member 40.

[0098] For example, a protrusion 65 is provided on the inner surface of the cover portion 56. The protrusion 65 protrudes from the inner surface of the cover portion 56 toward the first receiving opening 55. Therefore, when the protrusion 65 is disposed inside the insertion opening 42, the insertion opening 42 faces the cover portion 56 in the covering portion 51.

[0099] like Figure 3As shown, the protrusion 65 extends, for example, along the length direction of the wire harness body 11. The protrusion 65 extends, for example, along the entire length of the covering portion 51. The protrusion 65 is partially provided, for example, in the circumferential direction of the cover portion 56. The protrusion 65 is provided, for example, in the middle portion of the circumferential direction of the cover portion 56. Partially, the protrusion 65 forms, for example, a cover-side limiting wall 62. For example, a protrusion 65 provided at one end of the covering portion 51 in the length direction forms a cover-side limiting wall 62.

[0100] like Figure 6 As shown, the protrusion 65 has, for example, a protrusion 66 that enters the annular recess 32 of the outer component 30. The protrusion 66 is provided further protruding from the protruding top surface of the protrusion 65. Multiple protrusions 66 are provided in the longitudinal direction of the wire harness body 11. In this embodiment, four protrusions 66 are provided in the longitudinal direction of the wire harness body 11, each entering a different annular recess 32.

[0101] (Structure of path restriction unit 70)

[0102] like Figure 2 As shown, the third main body 71 of the path limiting portion 70 extends, for example, along the path of the bending portion 11B. That is, the third main body 71 has a bent shape that follows the shape of the bending portion 11B. The third main body 71, for example, partially covers the circumferential periphery of the outer member 30. The third main body 71 is formed in a cylindrical shape that partially covers the circumferential periphery of the outer member 30. The third main body 71, for example, covers an area larger than half the circumference of the outer member 30. The cross-sectional shape of the inner surface of the third main body 71 is, for example, formed to correspond to the shape of the outer surface of the outer member 30. The cross-sectional shape of the inner surface of the third main body 71 is, for example, formed to be a curved shape. The cross-sectional shape of the inner surface of the third main body 71 is generally U-shaped.

[0103] The third main body 71 has a second receiving opening 63 that opens in a direction orthogonal to the length direction of the third main body 71. The second receiving opening 63 extends along the entire length direction of the third main body 71. The second receiving opening 63 communicates with the first receiving opening 55. The receiving opening formed by the first receiving opening 55 and the second receiving opening 63 extends along the entire length direction of the second path limiting member 50. That is, the receiving opening formed by the first receiving opening 55 and the second receiving opening 63 opens in a direction orthogonal to the length direction of the second path limiting member 50, and opens at both ends of the length direction of the second path limiting member 50.

[0104] The opening width of the second housing opening 63 is, for example, equal to or greater than the outer diameter of the outer member 30. In the second housing opening 63, the outer member 30 is inserted in a direction orthogonal to the length direction of the second path restriction member 50. Further, the first path restriction member 40 is not inserted in the inside of the third body portion 71.

[0105] (Structure of fixing members 81, 82)

[0106] The wire harness 10 has, for example, a fixing member 81 that fixes the first path restriction member 40 to the outer periphery of the outer member 30. The wire harness 10 has, for example, a fixing member 82 that fixes the second path restriction member 50 to the outer periphery of the outer member 30. As the fixing members 81, 82, for example, a resin-made or metal-made binding strap, a fastening ring, a tape, or the like can be used. The fixing members 81, 82 of the present embodiment are tapes.

[0107] The fixing member 81 is formed, for example, in a manner that an end portion of the first path restriction member 40 provided on the side opposite to the connection portion 47 is fixed to the outer surface of the outer member 30. The fixing member 81 is wound, for example, from the outer surface of the end portion of the first path restriction member 40 in the length direction to the outer surface of the outer member 30. Thereby, the movement of the first path restriction member 40 relative to the outer member 30 can be suppressed in the length direction and the circumferential direction of the wire harness body 11. The fixing member 82 is formed, for example, in a manner that an end portion of the second path restriction member 50 provided on the side opposite to the covering portion 51 is fixed to the outer surface of the outer member 30. The fixing member 82 is wound, for example, from the outer surface of the end portion of the second path restriction member 50 in the length direction to the outer surface of the outer member 30. Thereby, the movement of the second path restriction member 50 relative to the outer member 30 can be suppressed in the length direction and the circumferential direction of the wire harness body 11.

[0108] Next, the effects of the present embodiment will be described.

[0109] In the length direction of the wire harness body 11, the connection portion 47 of the first path restriction member 40 and the covering portion 51 of the second path restriction member 50 are provided so as to overlap. At this time, the restriction wall 60 that can be engaged with the end surface 47A of the first path restriction member 40 in the length direction is provided in the covering portion 51. Therefore, by engaging the end surface 47A with the restriction wall 60, the positioning of the first path restriction member 40 relative to the second path restriction member 50 can be easily performed when the first path restriction member 40 is fitted to the second path restriction member 50.

[0110] Next, the effects of the present embodiment will be described.

[0111] (1) The restriction wall 60 that can be engaged with the end surface 47A of the length direction of the first path restriction member 40 is provided at the cover portion 51 of the second path restriction member 50. According to this structure, by engaging the end surface 47A with the restriction wall 60, the positioning of the first path restriction member 40 with respect to the second path restriction member 50 can be easily performed when the first path restriction member 40 is fitted to the second path restriction member 50. Thus, the workability when the first path restriction member 40 is fitted to the second path restriction member 50 can be improved. Further, the assembly workability of the wire harness 10 can be improved.

[0112] (2) In addition, by engaging the end surface 47A with the restriction wall 60, the relative movement of the first path restriction member 40 with respect to the second path restriction member 50 in the length direction of the wire harness body 11 can be suppressed. Thus, the misalignment of the first path restriction member 40 with respect to the second path restriction member 50 in the length direction of the wire harness body 11 can be suppressed. As a result, the positional accuracy of the first path restriction member 40 with respect to the second path restriction member 50 can be improved. Here, in the present embodiment, the second path restriction member 50 is fixed to the outer cover member 30 of the wire harness body 11 by the fixing member 82. Thus, the movement of the second path restriction member 50 with respect to the wire harness body 11 in the length direction of the wire harness body 11 can be suppressed. Therefore, by improving the positional accuracy of the first path restriction member 40 with respect to the second path restriction member 50, the positional accuracy of the first path restriction member 40 with respect to the wire harness body 11 can be improved. As a result, the first path restriction member 40 can be appropriately disposed at the desired position of the wire harness body 11, here, the straight portion 11A, and the path of the straight portion 11A can be appropriately restricted by the first path restriction member 40. In other words, the positional deviation of the first path restriction member 40 with respect to the wire harness body 11 from the straight portion 11A can be appropriately suppressed.

[0113] (3) The insertion opening 42 of the first path restriction member 40 is opened in a direction orthogonal to the length direction of the first path restriction member 40 and extends over the entire length in the length direction of the first path restriction member 40. Thus, the first path restriction member 40 can be fitted to the outer cover member 30 from the insertion opening 42 after the end processing of fitting the connectors C1, C2 to the end portions in the length direction of the wire member 20 or the like is performed. In this way, the first path restriction member 40 can be installed later, and thus the assembly workability of the wire harness 10 can be improved.

[0114] (4) The cover portion 51 is formed in a ring shape that collectively surrounds the connection portion 47 and the exterior member 30. The cover portion 51 has a second body portion 52 that covers a part of the outer periphery of the first body portion 41, and a lid portion 56 that is connected to the second body portion 52. According to this structure, although the cover portion 51 is provided in a ring shape that surrounds the connection portion 47 and the exterior member 30, the cover portion 51 is divided into the second body portion 52 and the lid portion 56, so that the second path restriction member 50 including the cover portion 51 can be attached to the first path restriction member 40 and the exterior member 30. Thus, the assembly workability of the wire harness 10 can be further improved.

[0115] (5) The restriction wall 60 has a body-side restriction wall 61 that protrudes from the inner surface of the second body portion 52, and a lid-side restriction wall 62 that protrudes from the inner surface of the lid portion 56. According to this structure, in the case where the first path restriction member 40 is inserted into the second body portion 52 first, the lengthwise end surface 47A of the first path restriction member 40 can be engaged with the body-side restriction wall 61. Also, in the case where the first path restriction member 40 is inserted into the lid portion 56 first, the lengthwise end surface 47A of the first path restriction member 40 can be engaged with the lid-side restriction wall 62. Thus, in either case where the first path restriction member 40 is inserted into either the second body portion 52 or the lid portion 56 first, the positioning of the first path restriction member 40 with respect to the second path restriction member 50 can be easily performed.

[0116] (6) The second receiving opening 63 provided in the body-side restriction wall 61 is formed to have a smaller opening width than the outer diameter of the first path restriction member 40. Thus, in the case where the first path restriction member 40 is inserted into the cover portion 51, the lengthwise end surface 47A of the first path restriction member 40 can be properly engaged with the body-side restriction wall 61. Thus, the positioning of the first path restriction member 40 with respect to the second path restriction member 50 can be properly performed.

[0117] (7) The cover portion 51 has a protrusion portion 65 that can contact at least one of the first end portion 43 and the second end portion 44 that form the insertion opening 42 in the circumferential direction of the first path restriction member 40. Thus, in the circumferential direction of the first path restriction member 40, the protrusion portion 65 and the first end portion 43 or the second end portion 44 are engaged. By these engagements, the relative movement of the first path restriction member 40 with respect to the cover portion 51 in the circumferential direction can be suppressed. That is, by the mutual engagement of the protrusion portion 65 and the first end portion 43 or the second end portion 44, the circumferential rotation of the first path restriction member 40 with respect to the cover portion 51 can be suppressed. Thus, the misalignment of the first path restriction member 40 with respect to the cover portion 51 in the circumferential direction can be suppressed, and the positional accuracy of the first path restriction member 40 with respect to the cover portion 51 can be improved.

[0118] (8) The protruding portion 65 has a protruding portion 66 that enters the annular recessed portion 32 of the outer member 30, and thus movement of the outer member 30 relative to the second path regulating member 50 in the length direction of the outer member 30 is suppressed.

[0119] (9) A limiting wall 60 is provided at an end portion of the two end portions in the length direction of the cover portion 51 that is connected to the path regulating portion 70. By the limiting wall 60, the amount of insertion of the first path regulating member 40 relative to the second path regulating member 50 in the length direction of the wire harness main body 11 is suppressed. Thus, insertion of the first path regulating member 40 into the path regulating portion 70 of the second path regulating member 50 in the length direction of the wire harness main body 11 is suppressed. That is, excessive insertion of the first path regulating member 40 relative to the second path regulating member 50 in the length direction of the wire harness main body 11 is suppressed.

[0120] (10) The path of the straight portion 11A is regulated by the first path regulating member 40, and the path of the bent portion 11B is regulated by the second path regulating member 50. Thus, deviation of the path of the straight portion 11A and the path of the bent portion 11B from the desired paths is suppressed.

[0121] (11) The first path regulating member 40 has a protruding portion 45 that protrudes from the inner surface of at least one of the first end portion 43 and the second end portion 44 so as to be in contact with the outer surface of the outer member 30. By the protruding portion 45, the outer member 30 can be pressed, for example, from the outside of the outer member 30. Thus, the first path regulating member 40 can be appropriately prevented from coming off the outer member 30 through the insertion opening 42.

[0122] (Other Embodiments)

[0123] The above-described embodiments can be implemented by being changed as follows. The above-described embodiments and the following changed examples can be implemented in combination with each other within a range in which there is no technical contradiction.

[0124] • In the above-described embodiments, a gap is formed between the inner surface of the cover portion 56 and the outer surface of the first path regulating member 40, but this is not limiting.

[0125] For example Figure 7 As illustrated in FIG. 13, the inner surface of the cover portion 56 can be brought into close contact with the outer surface of the first path regulating member 40. For example, the inner surface of the cover portion 56 can be formed so as to press the outer surface of the first path regulating member 40 toward the radial inner side of the cover portion 51.

[0126] For example Figure 8As illustrated, an interference amount can also be provided between the outer periphery of the first path restriction member 40 and the inner periphery of the cover portion 51. For example, the minimum inner diameter d2 of the cover portion 51 can be formed to be smaller than the maximum outer diameter d1 of the first path restriction member 40 before the first path restriction member 40 is fitted to the outer periphery of the outer cover member 30 and inserted into the inside of the cover portion 51. In this case, the opening width of the insertion port 42 of the first path restriction member 40 in a state where the first path restriction member 40 is inserted into the inside of the outer cover member 30 becomes slightly larger than the original width, i.e., the width when the outer cover member 30 is not inserted. For example, the outer diameter of the first path restriction member 40 in a state where the first path restriction member 40 is inserted into the inside of the outer cover member 30 becomes larger than the outer diameter when the outer cover member 30 is not inserted by an amount of the protruding amount of the protruding portion 45. Thus, the maximum outer diameter d1 of the first path restriction member 40 before the first path restriction member 40 is fitted to the outer periphery of the outer cover member 30 and inserted into the inside of the cover portion 51 becomes the outer diameter of the portion passing through the protruding portion 45. Further, the minimum inner diameter d2 of the cover portion 51 is the inner diameter of the cover portion 51 at a position corresponding to the maximum outer diameter d1. The minimum inner diameter d2 is set to be smaller than the maximum outer diameter d1 by an amount of the protruding amount of the protruding portion 45, for example.

[0127] By thus setting the maximum outer diameter d1 and the minimum inner diameter d2, the first path restriction member 40 fitted to the outer periphery of the outer cover member 30 is fitted to the inner periphery of the cover portion 51 in a manner having an interference amount. For example Figure 7 As illustrated, when the cover portion 56 is held in the closed position in a state where the outer cover member 30 and the first path restriction member 40 are accommodated in the inside of the cover portion 51, the first path restriction member 40 is fitted to the inner periphery of the cover portion 51 in a manner having an interference amount. Thus, the inner peripheral surface of the cover portion 51 and the outer peripheral surface of the first path restriction member 40 are in contact in a state having an interference amount. In this modification, the inner peripheral surface of the cover portion 51 and the outer peripheral surface of the first path restriction member 40 are in contact in a state having an interference amount only at a plurality of positions separated in the circumferential direction of the cover portion 51. Thus, the first path restriction member 40 fitted to the inside of the cover portion 51 is held in a state where the inner surface of the cover portion 51 presses the first path restriction member 40 toward the radial inner side of the cover portion 51 at all times. Thus, the first path restriction member 40 can be inhibited from shaking in the inside of the cover portion 51. Further, the relative movement of the first path restriction member 40 with respect to the cover portion 51 in the length direction of the wire harness body 11 can be appropriately inhibited. As a result, the first path restriction member 40 can be appropriately inhibited from being misaligned with respect to the cover portion 51 in the length direction of the wire harness body 11, and the first path restriction member 40 can be appropriately inhibited from coming off the cover portion 51. Further, the relative movement of the first path restriction member 40 with respect to the cover portion 51 in the circumferential direction of the wire harness body 11 can also be appropriately inhibited.

[0128] Further, in Figure 7 and Figure 8 , the illustration of the electric wire member 20 is omitted.

[0129] • The structure of the second path restriction member 50 of the above embodiment can be appropriately changed.
