DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The wire harness of the present disclosure includes: [1] A wire harness main body having an electric wire member and an exterior member covering an outer periphery of the electric wire member; a first path regulating member attached to the outer periphery of the exterior member and regulating a path of the wire harness main body; and an attachment member attached to the outer periphery of the first path regulating member at a portion of its longitudinal direction, wherein the first path regulating member has an insertion opening that opens in a direction perpendicular to the longitudinal direction of the first path regulating member and extends over the entire longitudinal direction of the first path regulating member, and the attachment member has a receiving portion that covers a portion of the circumferential direction of the first path regulating member, and a flexible band that, together with the receiving portion, covers the entire circumference of the first path regulating member and binds the receiving portion and the first path regulating member together.

[0010] According to this configuration, the receiving portion and the first path regulating member are bound together by a flexible band that covers the entire circumference of the first path regulating member together with the receiving portion that covers a portion of the circumference of the first path regulating member. In this way, rattling between the receiving portion and the first path regulating member is suppressed compared to a configuration in which, for example, a lid is integrally formed with the receiving portion via a thin hinge portion, and the lid is locked to the receiving portion by engagement of the claw portion in the closed state. That is, in a configuration having a thin hinge portion and claw portion, rattling between the receiving portion and the lid is likely to occur at each portion of the hinge portion and the claw portion, but this can be avoided. Therefore, the receiving portion and the band can hold the first path regulating member without rattling, and rattling between the first path regulating member and the attachment member can be suppressed.

[0011] [2] The band is a cable tie having a flexible strip portion and a lock portion provided at the longitudinal end of the strip portion for restricting movement of the strip portion in the removal direction, which is the opposite direction to the direction in which the strip portion is passed through, when the strip portion is passed through. It is preferable that the cable tie is attached so as to cover the entire circumferential direction of the receiving portion and to cover the entire circumference of the first path regulating member together with the receiving portion.

[0012] According to this configuration, since the band is a cable tie having a belt-shaped portion and a locking portion, for example, a well-known one can be used and is easy to obtain. In addition, since the cable tie is attached so as to cover the entire circumference of the first path regulating member together with the receiving portion while covering the entire circumferential direction of the receiving portion, it is possible to tie the first path regulating member in a tightening manner, and rattling between the receiving portion and the first path regulating member can be effectively suppressed.

[0013] [3] It is preferable that the receiving portion has an engaging portion capable of engaging with the strip portion in the longitudinal direction of the receiving portion. According to this configuration, since the receiving portion has an engaging portion that can engage with the band-shaped portion in the length direction of the receiving portion, it is possible to prevent the band-shaped portion from shifting in the length direction of the receiving portion, and therefore it is possible to stably prevent rattling between the receiving portion and the first path regulating member.

[0014] [4] It is preferable that the engagement portion is provided at both circumferential ends of the receiving portion. According to this configuration, the engaging portions are provided at both circumferential ends of the receiving portion, so that the band-shaped portion can be effectively prevented from shifting in the length direction of the receiving portion.

[0015] [5] It is preferable that the band extends from one circumferential end of the receiving portion and is fixed at the other end to bind the receiving portion and the first path regulating member together. [6] It is preferable that the band is integrally molded with the receiving portion.

[0016] According to this configuration, since the band is integrally molded with the receiving portion, the number of parts can be reduced compared to a configuration in which the band and the receiving portion are separate. [7] It is preferable that the mounting member is a second path regulating member attached to the outer periphery of the exterior member and regulating the path of the wire harness main body, and the receiving portion is provided at a longitudinal end of the second path regulating member and covers a circumferential portion of the longitudinal end of the first path regulating member.

[0017] According to this configuration, the receiving portion is provided at the end of the second path regulating member in the longitudinal direction and covers a part of the circumferential direction at the end of the first path regulating member in the longitudinal direction, so that the first path regulating member and the second path regulating member are connected in the longitudinal direction. Thus, the path of the wire harness main body is continuously regulated by the first path regulating member and the second path regulating member.

[0018] [8] It is preferable that the first path regulating member regulates the path of a straight portion, which is a straight portion in the path of the wire harness main body, and the second path regulating member regulates the path of a bent portion, which is a bent portion in the path of the wire harness main body.

[0019] According to this configuration, 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 continuously preventing the paths of the straight portion and the bent portion of the wire harness from deviating from the desired paths.

[0020] [Details of the embodiment of the present disclosure] Specific examples of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, some of the configuration may be exaggerated or simplified. In addition, the dimensional ratio of each part may differ in each drawing. In this specification, "parallel" and "orthogonal" do not only mean strictly parallel or orthogonal, but also include roughly parallel or orthogonal within the range in which the action and effect of this embodiment is achieved. Note that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0021] (Overall configuration of the wire harness 10) A wire harness 10 shown in FIG. 1 is mounted on a vehicle V such as a hybrid vehicle or an electric vehicle. The wire harness 10 electrically connects two or more in-vehicle devices to each other. The in-vehicle devices are electrical devices mounted on the vehicle V. The wire harness 10 electrically connects, for example, an inverter M1 installed at the front of the vehicle V and a high-voltage battery M2 installed behind the inverter M1 on the vehicle V. The wire harness 10 is formed in an elongated shape so as to extend, for example, in the front-rear direction of the vehicle V. The wire harness 10 is routed in the vehicle V so that, for example, a middle portion of the length of the wire harness 10 passes outside the passenger compartment, such as under the floor of the vehicle V.

[0022] The inverter M1 is connected to, for example, a wheel drive motor (not shown) that serves as a power source for driving the vehicle. The inverter M1 generates AC power from DC power of a high-voltage battery M2 and supplies the AC power to the motor. The high-voltage battery M2 is, for example, a battery capable of supplying a voltage of several hundred volts.

[0023] The wire harness 10 has a wire harness main body 11. The wire harness main body 11 has an electric wire member 20 and a cylindrical exterior member 30 that covers the outer periphery of the electric wire member 20. The wire harness 10 has connectors C1, C2 attached to both ends of the electric wire member 20. One end in the length direction of the electric wire member 20 is connected to the inverter M1 via the connector C1, and the other end in the length direction of the electric wire member 20 is connected to the high-voltage battery M2 via the connector C2.

[0024] 2 and 3, the wire harness 10 has a first path regulating member 40 attached to the outer periphery of the exterior member 30, and a second path regulating member 60 as an attachment member attached to the outer periphery of the exterior member 30. The first path regulating member 40 and the second path regulating member 60 regulate the route along which the wire harness main body 11 is routed. Note that the first path regulating member 40 and the second path regulating member 60 are not shown in FIG.

[0025] (Configuration of the electric wire member 20) As shown in Figures 4 and 6, the electric wire member 20 may be, for example, one or more electric wires, and in this embodiment, it has two electric wires 21 and a braided member 25 that collectively surrounds the outer periphery of the multiple electric wires 21.

[0026] As shown in Fig. 6, each electric wire 21 is a covered electric wire having a conductive core wire 22 and an insulating covering 23 that surrounds the outer periphery of the core wire 22 and has insulating properties. Each electric wire 21 is, for example, a high-tension electric wire that can handle high voltage and large current. Each electric wire 21 may be, for example, a non-shielded electric wire that does not have an electromagnetic shield structure itself, or a shielded electric wire that has an electromagnetic shield structure itself. Each electric wire 21 in this embodiment is a non-shielded electric wire.

[0027] The core wire 22 may be, for example, a stranded wire made of a plurality of metal wires stranded together, or a single core wire made of a single conductor. The single core wire may be, for example, a columnar conductor made of a single metal rod having a solid interior structure, or a tubular conductor having a hollow interior structure. The core wire 22 may be a combination of a stranded wire, a columnar conductor, and a tubular conductor. The material of the core wire 22 may be, for example, a copper-based or aluminum-based metal material.

[0028] The insulating coating 23, for example, covers the entire outer circumferential surface of the core wire 22. The insulating coating 23 is made of, for example, a resin material having insulating properties. The cross-sectional shape of each electric wire 21 cut by a plane perpendicular to the length direction of each electric wire 21, that is, the transverse cross-sectional shape of each electric wire 21, can be formed into any shape. The transverse cross-sectional shape of each electric wire 21 is formed into, for example, a circular shape, a semicircular shape, a polygonal shape, a square shape, a flat shape, or the like. The transverse cross-sectional shape of each electric wire 21 in this embodiment is formed into a circular shape.

[0029] The braided member 25 has, for example, a cylindrical shape that collectively surrounds the outer circumference of the plurality of electric wires 21. As the braided member 25, for example, a braided wire in which a plurality of metal wires are woven, or a braided wire in which metal wires and resin wires are combined and woven, can be used. As the material of the metal wires, for example, a copper-based or aluminum-based metal material can be used. Although not shown in the drawings, both ends of the braided member 25 in the length direction are earthed, for example, by connectors C1 and C2 (see FIG. 1).

[0030] (Configuration of exterior member 30) As shown in Fig. 4, the exterior member 30 has a tubular shape surrounding the outer periphery of the electric wire member 20 over the entire circumferential direction. The exterior member 30 of this embodiment is formed in a cylindrical shape. For example, the exterior member 30 has a peripheral wall formed continuously over the entire circumferential direction of the exterior member 30. For example, the exterior member 30 seals the inside of the exterior member 30 over the entire circumferential direction. The exterior member 30 has a function of protecting the electric wire member 20 from flying objects and water droplets, for example.

[0031] The exterior member 30 is, for example, flexible and easily bendable. Examples of the flexible exterior member 30 include, for example, a resin corrugated tube and a rubber waterproof cover. The exterior member 30 of this embodiment is a resin corrugated tube having a bellows shape in which the diameters are repeatedly increased and decreased in the length direction of the exterior member 30. That is, the exterior member 30 of this embodiment has a bellows structure in which large diameter parts 31 and small diameter parts 32 having a diameter smaller than the large diameter parts 31 are alternately provided along the length direction of the exterior member 30. Each of the large diameter parts 31 and the small diameter parts 32 is, for example, an annular shape that goes around once along the circumferential direction of the exterior member 30. As the material of the exterior member 30, for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin can be used. In addition, in Figs. 1 to 3, the exterior member 30 is illustrated in a simplified form in order to simplify the drawings.

[0032] (Configuration of the first path regulating member 40 and the second path regulating member 60) As shown in Fig. 2 and Fig. 3, each of the first path regulating member 40 and the second path regulating member 60 holds the exterior member 30. Each of the first path regulating member 40 and the second path regulating member 60 is, for example, harder than the exterior member 30. Each of the first path regulating member 40 and the second path regulating member 60 has a hardness that makes it difficult to bend in a direction perpendicular to the length direction of the wire harness main body 11 compared to the exterior member 30. As a result, each of the first path regulating member 40 and the second path regulating member 60 regulates the path of the wire harness main body 11. For example, each of the first path regulating member 40 and the second path regulating member 60 assists the exterior member 30 so that the wire harness main body 11 does not bend due to its own weight or the like and deviate from a desired path.

[0033] As shown in FIG. 2, the first path regulating member 40 is provided partially in the length direction of the wire harness main body 11. The first path regulating member 40 is attached to the outer periphery of the exterior member 30, for example, at a straight portion 11A that is a straight portion of the path of the wire harness main body 11. The first path regulating member 40 regulates the path of the wire harness main body 11 at the straight portion 11A. Here, the straight portion 11A is a portion where the path of the wire harness main body 11 extends linearly in one direction. Note that one or more first path regulating members 40 are provided depending on the path of the wire harness main body 11.

[0034] The second path regulating member 60 is provided partially in the length direction of the wire harness main body 11. The second path regulating member 60 is attached to the outer periphery of the exterior member 30 at, for example, a bent portion 11B which is a bent portion of the path of the wire harness main body 11. The second path regulating member 60 regulates the path of the wire harness main body 11 at the bent portion 11B. Here, the bent portion 11B is a portion where the path of the wire harness main body 11 is bent so as to deviate from a straight line. Note that one or more second path regulating members 60 are provided depending on the path of the wire harness main body 11.

[0035] (Configuration of the first path regulating member 40) As shown in FIG. 6, the first path regulating member 40 covers a part of the outer periphery of the exterior member 30 in the circumferential direction of the exterior member 30. The first path regulating member 40 has a shape that covers the outer periphery of the exterior member 30 in a part of the circumferential direction of the exterior member 30. The cross-sectional shape of the first path regulating member 40 is generally C-shaped. The first path regulating member 40 covers, for example, a range larger than half of the outer periphery of the exterior member 30. That is, the first path regulating member 40 covers, for example, a range larger than half of the entire circumferential direction of the exterior member 30 in the outer periphery of the exterior member 30. As shown in FIG. 2, the first path regulating member 40 extends along the length direction of the exterior member 30 in the straight portion 11A. The first path regulating member 40 is formed, for example, in a shape that extends linearly in one direction. The cross-sectional shape of the first path regulating member 40 is, for example, uniform over the entire length of the first path regulating member 40 in the length direction.

[0036] The first path regulating member 40 is made of, for example, metal or resin. The first path regulating member 40 of this embodiment is made of resin. As the material of the first path regulating member 40, for example, synthetic resin such as polypropylene, polyamide, polyacetal, etc. can be used. The first path regulating member 40 can be manufactured by a well-known manufacturing method such as extrusion molding or injection molding. In this embodiment, the first path regulating member 40 is an extrusion molded product manufactured by extrusion molding. Therefore, the first path regulating member 40 can be easily manufactured by using an extrusion molding machine that extrudes the raw material of the first path regulating member 40 in the length direction. In addition, a single extrusion molding machine can be used to manufacture multiple types of first path regulating members 40 with different length dimensions. For example, a cutting machine can be used to cut the base material of the first path regulating member 40 formed by a single extrusion molding machine at any length to manufacture multiple types of first path regulating members 40 with different length dimensions.

[0037] The first path regulating member 40 has an insertion opening 40X that opens in a direction perpendicular to the length direction of the first path regulating member 40. The insertion opening 40X extends over the entire length direction of the first path regulating member 40. The first path regulating member 40 has a first end 41 and a second end 42 that are both ends of the first path regulating member 40 in the circumferential direction and form the insertion opening 40X. The first path regulating member 40 has a connecting portion 43 that connects the first end 41 and the second end 42. In other words, the first path regulating member 40 has the connecting portion 43 formed so as to cover a part of the circumferential direction of the exterior member 30, the first end 41 and the second end 42 provided at both ends of the connecting portion 43, and the insertion opening 40X formed by the first end 41 and the second end 42.

[0038] 6, the connecting portion 43 constitutes a main portion of the first path regulating member 40. The radial thickness of the connecting portion 43 is, for example, uniform in the circumferential direction of the first path regulating member 40. The cross-sectional shape of the connecting portion 43 is, for example, formed into a shape that follows the outer surface of the exterior member 30. The cross-sectional shapes of the first end portion 41, the second end portion 42, and the connecting portion 43 are, for example, formed into an arc shape.

[0039] The first end 41 and the second end 42 are provided on opposite sides of the first path regulating member 40 in the circumferential direction. The first end 41 and the second end 42 are provided apart from each other in the circumferential direction of the first path regulating member 40, sandwiching the insertion opening 40X therebetween. In other words, a gap between the first end 41 and the second end 42 in the circumferential direction of the first path regulating member 40 is configured as the insertion opening 40X. In this manner, the first path regulating member 40 is formed in a C-shape having the insertion opening 40X at a portion of the circumferential direction of the first path regulating member 40.

[0040] The cross-sectional shape of the tip of the first end portion 41 and the second end portion 42 is formed into a curved shape. In this embodiment, the cross-sectional shape of the tip of the first end portion 41 and the second end portion 42 is formed into an arc shape.

[0041] The first path regulating member 40 has a protruding portion 45 protruding from the inner surface of the first end portion 41 and a protruding portion 46 protruding from the inner surface of the second end portion 42. Each of the protruding portions 45, 46 protrudes toward the exterior member 30 inserted inside the first path regulating member 40 and contacts the outer surface of the exterior member 30. Each of the protruding portions 45, 46 contacts the outer surface of the large diameter portion 31 of the exterior member 30. The protruding portion 45 protrudes, for example, from the inner surface of the tip of the first end portion 41. The protruding portion 46 protrudes, for example, from the inner surface of the tip of the second end portion 42. The cross-sectional shape of each of the protruding portions 45, 46 is formed, for example, in a curved shape. The cross-sectional shape of each of the protruding portions 45, 46 in this embodiment is formed in an arc shape.

[0042] 3, each of the protrusions 45, 46 extends in the length direction of the first path regulating member 40. Each of the protrusions 45, 46 extends, for example, over the entire length of the first path regulating member 40 in the length direction.

[0043] The protruding portions 45, 46 press the exterior member 30 from the outside of the exterior member 30. The exterior member 30 is elastically sandwiched between the protruding portions 45, 46, and the connecting portion 43. This makes the connection of the first path regulating member 40 to the exterior member 30 strong.

[0044] As shown in FIG. 6, the opening width of the insertion opening 40X, that is, the shortest distance between the first end 41 and the second end 42, is smaller than the outer diameter of the exterior member 30. The opening width of the insertion opening 40X becomes larger as the first path regulating member 40 elastically deforms. For example, the opening width of the insertion opening 40X becomes larger as the exterior member 30 is inserted into the insertion opening 40X from a direction perpendicular to the length direction of the first path regulating member 40. When the exterior member 30 is inserted into the first path regulating member 40, the first path regulating member 40 elastically returns to its original shape. As a result, the opening width of the insertion opening 40X becomes smaller than the outer diameter of the exterior member 30, and the first path regulating member 40 is attached to the outer periphery of the exterior member 30.

[0045] (Configuration of the second path regulating member 60) 2, the second path regulating member 60 is attached to the outer periphery of a portion of the first path regulating member 40 in the longitudinal direction. The second path regulating member 60 is attached to the outer periphery of an end portion of the first path regulating member 40 in the longitudinal direction. The second path regulating member 60 is also attached to the outer periphery of the exterior member 30 at the bent portion 11B. The second path regulating member 60 extends along the longitudinal direction of the exterior member 30 at the bent portion 11B. The second path regulating member 60 is bent, for example, to follow the shape of the bent portion 11B.

[0046] The second path regulation member 60 has a second path regulation body 61 and a binding band 62 serving as a band. The second path regulating body 61 and the cable tie 62 constituting the second path regulating member 60 are each made of, for example, metal or resin. In this embodiment, the second path regulating body 61 and the cable tie 62 are made of resin. As the material for the second path regulating body 61 and the cable tie 62, for example, a synthetic resin such as polypropylene, polyamide, or polyacetal can be used. The second path regulating body 61 and the cable tie 62 can be manufactured by a well-known manufacturing method such as injection molding.

[0047] The second path regulation body 61 has a body portion 64 and a receiving portion 65 . The main body portion 64 covers a part of the outer periphery of the exterior member 30 in the circumferential direction of the exterior member 30. The main body portion 64 has a shape that covers the outer periphery of the exterior member 30 in a part of the circumferential direction of the exterior member 30. The cross-sectional shape of the main body portion 64 is a semi-cylindrical shape as a whole. The main body portion 64 covers half of the outer periphery of the exterior member 30. As shown in FIG. 2, the main body portion 64 extends along the length direction of the exterior member 30 at the bent portion 11B. The main body portion 64 is bent along the shape of the bent portion 11B.

[0048] The receiving portion 65 is provided at the end of the second path regulating member 60 in the length direction, which is also the end of the main body portion 64 in the length direction. The receiving portion 65 covers a part of the circumferential direction of the first path regulating member 40 among the outer periphery of the first path regulating member 40. The receiving portion 65 covers a part of the circumferential direction at the end of the length direction of the first path regulating member 40. The receiving portion 65 is shaped to cover the outer periphery of the first path regulating member 40 in a part of the circumferential direction of the first path regulating member 40. The cross-sectional shape of the receiving portion 65 is a semi-cylindrical shape as a whole. The receiving portion 65 is shaped as a semi-cylindrical shape with a diameter larger than that of the main body portion 64. The receiving portion 65 covers half of the outer periphery of the first path regulating member 40.

[0049] As shown in Figs. 2 to 6, the receiving portion 65 has an engagement portion 66. The engagement portion 66 is provided at both circumferential ends of the receiving portion 65. The engagement portion 66 protrudes radially outward from both circumferential ends of the receiving portion 65. As shown in Fig. 5, two engagement portions 66 are provided in the length direction of the receiving portion 65. As shown in Fig. 6, the engagement portion 66 has a through hole 67. The through hole 67 penetrates in the tangent direction of an arc along the outer circumferential surface of the receiving portion 65. The through holes 67 in both circumferential engaging portions 66 of the receiving portion 65 have parallel penetration directions.

[0050] The cable tie 62 covers the entire periphery of the first path regulating member 40 together with the receiving portion 65 and ties the receiving portion 65 and the first path regulating member 40 together. More specifically, the cable tie 62 has a flexible belt-like portion 68 and a locking portion 69 provided at an end in the longitudinal direction of the belt-like portion 68. The locking portion 69 restricts the movement of the belt-like portion 68 in the removal direction, which is the opposite direction to the passing direction, while the belt-like portion 68 is in the passed state, thereby locking the belt-like portion 68.

[0051] The cable tie 62 is attached so that the band-shaped portion 68 is passed through the through hole 67 of the engagement portion 66 to cover the entire circumferential direction of the receiving portion 65 and to cover the entire circumference of the first path regulating member 40 together with the receiving portion 65. In other words, the cable tie 62 covers the entire circumferential direction along the outer periphery of the first path regulating member 40 together with the receiving portion 65. The cable tie 62 also ties the receiving portion 65 and the first path regulating member 40 together so that the first path regulating member 40 does not separate from the receiving portion 65. The engagement portion 66 is also capable of engaging with the band-shaped portion 68 in the length direction of the second path regulating member 60, which is the length direction of the receiving portion 65. The engagement portion 66 suppresses the band-shaped portion 68 from shifting in the length direction of the second path regulating member 60, which is the length direction of the receiving portion 65. The end portion of the band-shaped portion 68 that passes through the lock portion 69 becomes unnecessary. 2, 5 and 6, which show the state after the cable tie 62 has been attached, the tip portion of the belt-like portion 68 has been cut off.

[0052] As shown in FIG. 2, the wire harness 10 has a slide restricting member 70 that restricts the sliding movement of the first path restricting member 40 in the length direction of the exterior member 30. The wire harness 10 has a slide restricting member 71 that restricts the sliding movement of the second path restricting member 60 in the length direction of the exterior member 30. As the slide restricting members 70 and 71, for example, a resin or metal cable tie, a crimping ring, or an adhesive tape can be used. The slide restricting members 70 and 71 in this embodiment are adhesive tapes. The slide restricting member 70 is wound around an end of the first path restricting member 40 on a side not connected to the second path restricting member 60 and the exterior member 30. The slide restricting member 71 is wound around an end of the second path restricting member 60 on a side not connected to the first path restricting member 40 and the exterior member 30.

[0053] Next, the operation of this embodiment will be described. The receiving portion 65 and the first path regulating member 40 are tied together by the cable tie 62. This maintains the first path regulating member 40 and the second path regulating member 60 in a connected state. This allows the path of the wire harness main body 11 to be continuously regulated.

[0054] Next, the effects of the above embodiment will be described below. (1) The receiving portion 65 and the first path regulating member 40 are bound by a flexible cable tie 62 that covers the entire circumference of the first path regulating member 40 together with the receiving portion 65 that covers a part of the circumference of the first path regulating member 40. In this way, rattling between the receiving portion 65 and the first path regulating member 40 is suppressed compared to a configuration in which, for example, a lid is integrally formed with the receiving portion 65 via a thin hinge portion, and the lid is locked to the receiving portion 65 by engagement of the claw portion in the closed state. That is, in a configuration having a thin hinge portion and claw portion, rattling between the receiving portion 65 and the lid is likely to occur at each portion of the hinge portion and the claw portion, but this can be avoided. Therefore, the receiving portion 65 and the cable tie 62 can hold the first path regulating member 40 without rattling, and rattling between the first path regulating member 40 and the second path regulating member 60 can be suppressed. As a result, for example, damage to the attachment portion between the first path regulating member 40 and the second path regulating member 60 can be suppressed, and the path of the wire harness main body 11 can be stably regulated.

[0055] (2) The band that fastens the receiving portion 65 and the first path regulating member 40 is the cable tie 62 having the belt-shaped portion 68 and the locking portion 69, and therefore, for example, a well-known band can be used and is easily available. In addition, the cable tie 62 is attached so as to cover the entire circumference of the first path regulating member 40 together with the receiving portion 65 while covering the entire circumferential direction of the receiving portion 65, and therefore can fasten and fasten the entire circumference of the first path regulating member 40. Therefore, rattling between the receiving portion 65 and the first path regulating member 40 can be effectively suppressed.

[0056] (3) The receiving portion 65 has the engaging portion 66 that is engageable with the band-shaped portion 68 in the length direction of the second path regulating member 60, which is also the length direction of the receiving portion 65, and therefore can prevent the band-shaped portion 68 from shifting in the length direction of the receiving portion 65. Therefore, rattling between the receiving portion 65 and the first path regulating member 40 can be stably prevented.

[0057] (4) The engaging portions 66 are provided at both circumferential ends of the receiving portion 65, so that the band-shaped portions 68 can be effectively prevented from shifting in the length direction of the receiving portion 65. (5) The attachment member attached to the first path-regulating member 40 is the second path-regulating member 60 that is attached to the outer periphery of the exterior member 30 and regulates the path of the wire harness main body 11. The receiving portion 65 is provided at an end portion in the longitudinal direction of the second path-regulating member 60 and covers a part of the circumferential direction at the end portion in the longitudinal direction of the first path-regulating member 40, so that the first path-regulating member 40 and the second path-regulating member 60 are connected in the longitudinal direction. Thus, the path of the wire harness main body 11 is continuously regulated by the first path-regulating member 40 and the second path-regulating member 60.

[0058] (6) The path of the straight portion 11A of the wire harness main body 11 is restricted by the first path restricting member 40, and the path of the bent portion 11B of the wire harness main body 11 is restricted by the second path restricting member 60. This continuously prevents the paths of the straight portion 11A and the bent portion 11B of the wire harness main body 11 from deviating from the desired paths.

[0059] (Other embodiments) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.

[0060] In the above embodiment, the engagement portion 66 has a through hole 67, but it does not have to have a through hole 67 as long as it is capable of engaging with the band-shaped portion 68 in the longitudinal direction of the second path regulating member 60 and in the longitudinal direction of the receiving portion 65.

[0061] For example, it may be modified as shown in Fig. 7. In this example, the engaging portions 80 protrude from the outer peripheral surface of the receiving portion 65, and a pair are provided so as to be aligned in the length direction of the receiving portion 65. In this example, the pair of engaging portions 80 are provided so as to be aligned in the length direction of the receiving portion 65, i.e., two pairs. The band-shaped portion 68 is disposed so as to pass between the pair of engaging portions 80. In this manner, it is possible to prevent the band-shaped portion 68 from being shifted in the length direction of the receiving portion 65.

[0062] Furthermore, the engagement portion 80 in this example is provided at a circumferential intermediate portion of the receiving portion 65, rather than at both circumferential ends of the receiving portion 65. In this manner, the engagement portions 66, 80 may be provided at a circumferential intermediate portion of the receiving portion 65.

[0063] Additionally, the engagement portions 66, 80 may be provided over the entire circumferential surface of the receiving portion 65. Furthermore, any number of engaging portions 66, 80 may be provided in the circumferential direction of the receiving portion 65, such as three or more.

[0064] In the above embodiment, the receiving portion 65 has the engaging portions 66, 80. However, the present invention is not limited to this and may be configured so as not to have the engaging portions 66, 80. In the above embodiment, the second path regulating member 60 is configured to have two cable ties 62, but is not limited to this and may be configured to have one or three or more cable ties 62. Of course, the number of engagement portions 66, 80 may be changed depending on the number of cable ties 62.

[0065] In the above embodiment, the band is a cable tie 62 having a belt-shaped portion 68 and a locking portion 69, but the band may be changed to another flexible band that can tie together the receiving portion 65 and the first path regulating member 40 while covering the entire circumference of the first path regulating member 40 together with the receiving portion 65.

[0066] For example, the band may extend from one circumferential end of the receiving portion 65 and be fixed at the other end to bind the receiving portion 65 and the first path regulating member 40 together. Specifically, for example, as shown in FIG. 8, the band 81 may be modified. In this example, the band 81 is integrally molded with the receiving portion 82. That is, the band 81 is an integrally molded product with the receiving portion 82. The receiving portion 82 in this example does not have the engagement portion 66. The band 81 extends from one end of the receiving portion 82 in the circumferential direction. The band 81 is thinner and more flexible than the receiving portion 82. A band lock portion 83 is provided at the other end of the receiving portion 82 in the circumferential direction. The band lock portion 83 restricts the movement of the band 81 in the removal direction, which is the opposite direction to the passing direction, when the band 81 is passed through, thereby locking the band 81. The band 81 is passed through the band lock portion 83 while covering the entire circumference of the first path regulating member 40 together with the receiving portion 82, and binds the receiving portion 82 and the first path regulating member 40 together.

[0067] In this way, the band 81 can fasten the receiving portion 82 and the first path regulating member 40 with a short length. That is, the required length can be made shorter than, for example, the cable tie 62 or the like that is attached so as to cover the entire circumferential direction of the receiving portion 65 and to cover the entire circumference of the first path regulating member 40 together with the receiving portion 65 as in the above embodiment. Also, because the band 81 is integrally molded with the receiving portion 82, the number of parts can be reduced, for example, compared to a separate configuration.

[0068] The second path regulating member 60 in the above embodiment is formed to regulate the path of the bent portion 11B of the wire harness main body 11, but is not limited thereto. For example, the second path regulating member 60 may be changed to a shape that regulates the path of the straight portion 11A of the wire harness main body 11. In this case, for example, the bent shape of the main body portion 64 of the second path regulating member 60 is changed to a shape that extends linearly.

[0069] In the above embodiment, the attachment member attached to the first path regulating member 40 is embodied as the second path regulating member 60, but is not limited thereto. For example, the attachment member may be embodied as a vehicle attachment member for attaching the first path regulating member 40 to the vehicle V.

[0070] The structure of the first path regulating member 40 in the above embodiment can be modified as appropriate. For example, as long as the first path regulating member 40 has an insertion opening 40X and has a structure that allows it to be attached to the outer periphery of the exterior member 30, other structures are not particularly limited.

[0071] The protrusion 45 of the above embodiment may be provided at a position farther from the insertion opening 40X than the tip of the first end 41 in the circumferential direction of the first path regulating member 40. The protrusion 46 in the above embodiment may be provided at a position farther from the insertion opening 40X than the tip of the second end 42 in the circumferential direction of the first path regulating member 40.

[0072] The protruding portions 45 and 46 in the above embodiment may be provided partially in the length direction of the first path regulating member 40 . At least one of the protruding portions 45, 46 in the above embodiment may be omitted.

[0073] In the first path control member 40 of the above embodiment, the radial thickness of the connecting portion 43 may be configured to vary in the circumferential direction. The shape of the connecting portion 43 of the first path regulating member 40 in the above embodiment is not limited to a circular arc shape, but may be changed to, for example, an elliptical arc shape or a U-shape.

[0074] In the above embodiment, the first path regulating member 40 and the second path regulating member 60 are harder than the exterior member 30, but the present invention is not limited to this and may have a hardness equal to or less than that of the exterior member 30. In other words, the first path regulating member 40 and the second path regulating member 60 may act to make the wire harness main body 11 less likely to bend than the wire harness main body 11 in a state in which the first path regulating member 40 and the second path regulating member 60 are not attached.

[0075] The exterior member 30 in the above embodiment may be, for example, a metal layer containing a metal material provided on the outer surface of a corrugated tube made of resin. The exterior member 30 in the above embodiment is not limited to a corrugated tube, and may be, for example, an exterior member that does not have the large diameter portion 31 and the small diameter portion 32.

[0076] The exterior member 30 in the above embodiment may have a slit extending in the length direction of the exterior member 30. In the above embodiment, the electric wire 21 is a high-voltage electric wire. However, the present invention is not limited to this. For example, the electric wire 21 may be a low-voltage electric wire.

[0077] In the electric wire member 20 of the above embodiment, the electromagnetic shielding member is embodied as the braided member 25, but the present invention is not limited to this. For example, the electromagnetic shielding member in the electric wire member 20 may be embodied as a metal foil.

[0078] The braided member 25 in the electric wire member 20 of the above embodiment may be omitted. In the above embodiment, the electric wire member 20 includes two electric wires 21, but is not limited to this. The number of electric wires 21 may be one, or three or more.

[0079] The relative positions of the inverter M1 and the high-voltage battery M2 in the vehicle V are not limited to those in the above embodiment, and may be changed as appropriate depending on the vehicle configuration. In the above embodiment, the multiple on-board devices electrically connected to the wire harness 10 are embodied as the inverter M1 and the high-voltage battery M2, but are not limited thereto. The multiple on-board devices electrically connected to the wire harness 10 are not particularly limited as long as they are electrical devices mounted on the vehicle V.

[0080] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, not by the above meaning, and is intended to include all modifications within the meaning and scope of the claims.
