[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 in a part 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 covering a part of the circumferential direction of the first path regulating member, a lid covering the entire periphery of the first path regulating member together with the receiving portion, a first fixing portion provided at both circumferential ends of the receiving portion, a second fixing portion provided at both circumferential ends of the lid, and a fixing member attached to the overlapping first fixing portion and the second fixing portion and preventing the first fixing portion and the second fixing portion from being separated, and the receiving portion and the lid sandwich the first path regulating member.

[0010] According to this configuration, the first fixing portion is provided at both ends of the receiving portion in the circumferential direction, and the second fixing portion is provided at both ends of the lid in the circumferential direction. A fixing member is attached to the overlapped first fixing portion and second fixing portion, and the fixing member prevents the first fixing portion and the second fixing portion from being separated. In this way, rattling between the receiving portion and the lid is suppressed compared to a configuration in which, for example, the lid is integrally molded 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 first path regulating member can be sandwiched between the receiving portion and the lid without rattling, and rattling between the first path regulating member and the mounting member can be suppressed.

[0011] [2] It is preferable that the fixing member is attachable to the overlapping first fixing portion and the second fixing portion by sliding movement along the length of the mounting member.

[0012] According to this configuration, since the fixing member is attached by sliding movement along the length direction of the mounting member, it is possible to firmly prevent, for example, the first fixing part and the second fixing part from being separated. That is, for example, in a configuration in which the fixing member is attached while being bent from the radial outside of the mounting member, the fixing member is designed to be easily bent, which may cause the fixing member to easily come off from the first fixing part and the second fixing part, but this can be avoided.

[0013] [3] It is preferable that at least one of the first fixing portion and the second fixing portion has an engaging protrusion that allows the fixing member to be attached while engaging in a direction to remove the fixing member from the attached state, thereby preventing the fixing member from falling off.

[0014] According to this configuration, at least one of the first fixing portion and the second fixing portion has an engaging protrusion that allows the fixing member to be attached while engaging in the direction of removing it from the attached state to prevent the fixing member from falling off, thereby preventing the fixing member from falling off.

[0015] [4] It is preferable that the engaging protrusions are provided on both sides of the fixing member in the attached state in the longitudinal direction of the mounting member. According to this configuration, the engaging protrusions are provided on both sides of the fixing member in the attached state in the longitudinal direction of the mounting member, so that, for example, the fixing member can be attached from either side in the longitudinal direction of the mounting member.

[0016] [5] It is preferable that the fixing member is attachable to the overlapping first fixing portion and the second fixing portion from a radially outer side of the mounting member. According to this configuration, the fixing member is attached from the radially outer side of the mounting member, which makes it easy to attach the fixing member, for example.

[0017] [6] 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.

[0018] 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.

[0019] [7] 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.

[0020] 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 main body from deviating from the desired paths.

[0021] [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.

[0022] (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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] (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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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).

[0031] (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.

[0032] 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.

[0033] (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.

[0034] 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.

[0035] 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.

[0036] (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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] (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.

[0047] The second path regulating member 60 includes a second path regulating body 61 , a cover 62 , and a fixing member 63 . The second path regulating body 61, the lid 62, and the fixing member 63 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, the lid 62, and the fixing member 63 are made of resin. As materials for the second path regulating body 61, the lid 62, and the fixing member 63, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used. The second path regulating body 61, the lid 62, and the fixing member 63 can be manufactured by a well-known manufacturing method such as injection molding.

[0048] 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.

[0049] 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.

[0050] The receiving portion 65 has a first fixing portion 66. The first fixing portion 66 is provided at both ends of the receiving portion 65 in the circumferential direction. The first fixing portion 66 protrudes radially outward from both ends of the receiving portion 65 in the circumferential direction. As shown in FIG. 6, the first fixing portion 66 has a first mating surface 67 that is a plane continuous with the end surface in the circumferential direction of the receiving portion 65 and is along the radial direction of the second path regulating member 60. The first fixing portion 66 also has a first inclined surface 68 that is a surface on the opposite side to the first mating surface 67 and is more distant from the first mating surface 67 as it approaches the radial outside of the second path regulating member 60. The first inclined surface 68 has an engaging protrusion 69. As shown in FIG. 5, two engaging protrusions 69 are provided in the length direction of the receiving portion 65. The engaging protrusions 69 are provided in the receiving portion 65 toward the ends of the receiving portion 65 in the length direction. The engaging protrusions 69 are spherical. More specifically, the engaging protrusion 69 has a shape in which less than half of a sphere is cut off along one flat surface.

[0051] The lid 62, together with the receiving portion 65, covers the entire circumference of the first path regulating member 40. More specifically, the lid 62, together with the receiving portion 65, covers the entire circumferential direction along the outer periphery of the first path regulating member 40. The lid 62 of this embodiment covers a part of the outer periphery of the first path regulating member 40 and a part of the outer periphery of the exterior member 30 exposed from the insertion opening 40X. The cross-sectional shape of the lid 62 is semicylindrical as a whole. The lid 62 has a semicylindrical shape with the same diameter as the diameter of the receiving portion 65. The lid 62 covers a part of the circumferential direction along the outer periphery of the first path regulating member 40 that is not covered by the receiving portion 65, and covers half of the circumferential direction along the outer periphery of the first path regulating member 40.

[0052] The lid 62 has a second fixing portion 70. The second fixing portion 70 is provided at both ends of the lid 62 in the circumferential direction. The second fixing portion 70 protrudes radially outward from both ends of the lid 62 in the circumferential direction. As shown in FIG. 6, the second fixing portion 70 has a second mating surface 71 that is a plane continuous with the end surface in the circumferential direction of the lid 62 and is along the radial direction of the second path regulating member 60. The second fixing portion 70 also has a second inclined surface 72 that is a surface opposite to the second mating surface 71 and is more distant from the second mating surface 71 as it moves toward the radial outside of the second path regulating member 60. The second inclined surface 72 has an engaging protrusion 73. As shown in FIG. 5, two engaging protrusions 73 are provided in the length direction of the lid 62. The engaging protrusions 73 are provided in the lid 62 toward the ends of the lid 62 in the length direction. The engaging protrusions 73 are spherical. Specifically, the engaging protrusion 73 has a shape in which less than half of a sphere is cut off along a single plane.

[0053] The receiving portion 65 and the lid 62 are configured to cover the entire circumference of the first path regulating member 40 and sandwich the first path regulating member 40 when the first fixing portion 66 and the second fixing portion 70 are overlapped and the first mating surface 67 and the second mating surface 71 are overlapped.

[0054] The fixing member 63 is attached to the overlapped first fixing portion 66 and second fixing portion 70 to prevent the first fixing portion 66 and the second fixing portion 70 from being separated. In detail, the fixing member 63 has a fixing connecting portion 74, a first claw 75 protruding from one end of the fixing connecting portion 74 and capable of contacting the first inclined surface 68, and a second claw 76 protruding from the other end of the fixing connecting portion 74 and capable of contacting the second inclined surface 72. The first claw 75 and the second claw 76 are formed so as to protrude from both ends of the fixing connecting portion 74 and to be closer to each other toward the tip side. The fixing member 63 prevents the first fixing portion 66 and the second fixing portion 70 from being separated by sandwiching the overlapped first fixing portion 66 and the second fixing portion 70 with the first claw 75 and the second claw 76.

[0055] The fixing member 63 is attached to the first fixing portion 66 and the second fixing portion 70, which are overlapped with each other, by sliding movement along the length direction of the first path regulating member 40. As shown in FIG. 5, the fixing member 63 is attached between the engaging protrusions 69, 73 in the length direction of the second path regulating member 60. In other words, the engaging protrusions 69, 73 are provided on both sides of the fixing member 63 in the attached state in the length direction of the second path regulating member 60. Here, the engaging protrusions 69, 73 allow the fixing member 63 to be attached by sliding movement along the length direction of the second path regulating member 60. That is, the engaging protrusions 69, 73 protrude to an extent that the first claw 75 and the second claw 76 of the fixing member 63 can get over when the fixing member 63 is attached, by the fixing member 63 being slightly bent, for example. In addition, the engaging protrusions 69, 73 engage with the fixing member 63 in the direction of removing the attached fixing member 63, thereby preventing the fixing member 63 from falling off. In other words, the engaging protrusions 69, 73 engage with the fixed member 63 to such an extent that the attached fixed member 63 does not slide along the length direction of the second path regulating member 60 even if a small force such as vibration is applied to the second path regulating member 60.

[0056] As shown in FIG. 2, the wire harness 10 has a slide restricting member 77 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 78 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 77 and 78, for example, a resin or metal cable tie, a crimping ring, or an adhesive tape can be used. The slide restricting members 77 and 78 in this embodiment are adhesive tapes. The slide restricting member 77 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 78 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.

[0057] Next, the operation of this embodiment will be described. The receiving portion 65 and the lid 62 are maintained in a state in which the first path regulating member 40 is sandwiched between them by the fixing member 63. Thus, the first path regulating member 40 and the second path regulating member 60 are maintained in a connected state. Thus, the path of the wire harness main body 11 is continuously regulated.

[0058] Next, the effects of the above embodiment will be described below. (1) The first fixing portion 66 is provided at both circumferential ends of the receiving portion 65, and the second fixing portion 70 is provided at both circumferential ends of the lid 62. The fixing member 63 is attached to the overlapping first fixing portion 66 and second fixing portion 70, and the fixing member 63 prevents the first fixing portion 66 and the second fixing portion 70 from being separated. In this way, rattling between the receiving portion 65 and the lid 62 is suppressed compared to a configuration in which the lid 62 is integrally molded with the receiving portion 65 via a thin hinge portion and the lid 62 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 62 is likely to occur at each portion of the hinge portion and the claw portion, but this can be avoided. Therefore, in this embodiment, the first path regulating member 40 can be sandwiched between the receiving portion 65 and the lid 62 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.

[0059] (2) Since the fixing member 63 is attached by sliding movement along the length direction of the second path regulating member 60, it is possible to firmly prevent, for example, the first fixing portion 66 and the second fixing portion 70 from being separated. That is, for example, in a configuration in which the fixing member is attached while being bent from the radially outer side of the second path regulating member 60, the fixing member is designed to be easily bent, which may cause the fixing member to easily come off the first fixing portion 66 and the second fixing portion 70, but this can be avoided.

[0060] (3) The first fixing portion 66 and the second fixing portion 70 have engaging protrusions 69, 73 that allow the fixing member 63 to be attached while engaging in the direction of removing the fixing member 63 from the attached state, thereby preventing the fixing member 63 from falling off.

[0061] (4) Since the engaging protrusions 69, 73 are provided on both sides of the fixing member 63 in the attached state in the longitudinal direction of the second path regulating member 60, for example, it becomes possible to attach the fixing member 63 from either side in the longitudinal direction of the second path regulating member 60.

[0062] (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.

[0063] (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.

[0064] (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.

[0065] In the above embodiment, the first fixing portion 66 and the second fixing portion 70 have engaging protrusions 69, 73, but this is not limited to this, and a configuration in which only one of the first fixing portion 66 and the second fixing portion 70 has these protrusions, or a configuration in which neither of them has these protrusions, may be used.

[0066] In the above embodiment, the engagement protrusions 69, 73 are provided on both sides of the fixing member 63 in the attached state in the longitudinal direction of the second path regulating member 60, but this is not limited to this and may be changed to another configuration.

[0067] 7, for example, the engaging protrusions 69, 73 may be provided only on one side of the fixing member 63 in the attached state in the longitudinal direction of the second path regulating member 60, and a restricting portion 80 that does not allow the fixing member 63 to be attached on the other side of the fixing member 63 may be provided. The restricting portion 80 extends in the circumferential direction of the second path regulating member 60 from the ends of the first fixing portion 66 and the second fixing portion 70. In this way, the fixing member 63 can be attached to the overlapped first fixing portion 66 and the second fixing portion 70 only from one side in the longitudinal direction of the second path regulating member 60, and the restricting portion 80 restricts the fixing member 63 from slipping out to the other side in the longitudinal direction of the second path regulating member 60.

[0068] In the above embodiment, the fixing member 63 is attachable to the overlapping first fixing portion 66 and second fixing portion 70 by sliding movement along the length direction of the second path regulating member 60, but this is not limited to the above and the fixing member 63 may be configured to be attachable from another direction.

[0069] For example, as shown in Figs. 8 and 9, the fixing member 90 may be modified. The fixing member 90 of this example is attachable to the overlapped first fixing portion 66 and second fixing portion 70 from the radially outer side of the second path regulating member 60, and is attached from the radially outer side of the second path regulating member 60. The angle of the first inclined surface 68 of the first fixing portion 66 and the angle of the second inclined surface 72 of the second fixing portion 70, and the shape and material of the fixing member 90 are changed to a configuration in which the fixing member 90 can be attached while being bent from the radially outer side of the second path regulating member 60. In this example, the engaging protrusions 69 and 73 of the above embodiment are eliminated, and a restricting portion 91 is provided. The restricting portion 91 extends from both ends of the first fixing portion 66 and the second fixing portion 70 in the length direction of the second path regulating member 60 in the circumferential direction of the second path regulating member 60. In this example, the restricting portion 91 is provided around the entire circumference of the second path regulating member 60.

[0070] In this way, the fixing member 90 is attached from the radial outside of the second path regulating member 60, which, for example, facilitates attachment of the fixing member 90. In addition, in this way, the restricting portion 91 firmly restricts sliding movement of the receiving portion 65, the lid 62, and the fixing member 90 in the length direction of the second path regulating member 60.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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, but this is not limited thereto. For example, the electric wire 21 may be a low-voltage electric wire.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.
