Embodiments for Carrying Out the Invention

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. The wire harness of the present disclosure [1] A wire harness body having a wire member and an exterior member covering the outer periphery of the wire member, a first path regulating member attached to the outer periphery of the exterior member and regulating the path of the wire harness body, and an attachment member attached to the outer periphery of a part of the length direction of the first path regulating member, wherein the first path regulating member has an insertion opening that opens in a direction orthogonal to the length direction of the first path regulating member and extends over the entire length direction of the first path regulating member, and the attachment member has a covering portion covering the outer periphery of the first path regulating member and an elastic portion disposed in a compressed state between the covering portion and at least one of the first path regulating member and the exterior member.

[0010] According to the same configuration, since the first path regulating member has a covering portion covering the outer periphery of the first path regulating member and an elastic portion disposed in a compressed state between the covering portion and at least one of the first path regulating member and the exterior member, the first path regulating member is held by the covering portion while being pressed by the elastic portion. In this way, for example, compared with a configuration in which the covering portion is composed of a receiving portion and a lid, the 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 a claw portion in a closed state, rattling between the covering portion and the first path regulating member is suppressed. That is, in a configuration having a thin hinge portion and a claw portion, rattling between the receiving portion and the lid occurs at each part of the hinge portion and the claw portion, and as a result, rattling between the covering portion and the first path regulating member is likely to occur, but this can be avoided. Therefore, rattling between the first path regulating member and the attachment member can be suppressed.

[0011] [2] Preferably, a plurality of the elastic portions are provided in the circumferential direction of the covering portion. According to the same configuration, since a plurality of the elastic portions are provided in the circumferential direction of the covering portion, the first path regulating member is held by the covering portion while being pressed at a plurality of locations by the elastic portions. Therefore, for example, rattling between the first path regulating member and the attachment member can be further suppressed.

[0012] [3] Preferably, the elastic part is an integrally formed product made of the same material as the covering part. According to this configuration, since the elastic part is an integrally formed product made of the same material as the covering part, for example, an increase in the number of parts can be suppressed and it can be easily manufactured.

[0013] [4] Preferably, the elastic part constitutes a detent part that prevents the circumferential relative rotation of the first path restricting member with respect to the covering part by engaging with the insertion port in the circumferential direction of the first path restricting member.

[0014] According to this configuration, since the elastic part constitutes a detent part, the circumferential relative rotation of the first path restricting member with respect to the covering part is prevented. [5] Preferably, the elastic part is made of metal.

[0015] According to this configuration, since the elastic part is made of metal, for example, it is possible to strongly press at least one of the first path restricting member and the exterior member. [6] The elastic part is a metal plate that can be elastically deformed into either a first state in which it is bent so as to protrude radially outward of the covering part or a second state in which it is bent so as to protrude radially inward of the covering part, and is preferably arranged in a compressed state between the covering part and at least one of the first path restricting member and the exterior member in the second state.

[0016] According to this configuration, for example, it can be manufactured by elastically deforming the elastic part from the first state to the second state after arranging the first path restricting member inside the covering part, and the manufacturing becomes easy. [7] Preferably, the covering part has a receiving part that covers a part of the circumferential direction of the first path restricting member, and a lid that is fixed to the receiving part and covers the entire circumference of the first path restricting member together with the receiving part.

[0017] According to the same configuration, since the covering portion has a structure having a receiving portion and a lid, for example, the covering portion can be retrofitted to the first path restricting member. Thereby, for example, compared with the case where the covering portion is a non-deformable cylindrical shape, etc., the assembly workability of the wire harness is improved.

[0018] [8] The mounting member is a second path restricting member that is attached to the outer periphery of the exterior member and restricts the path of the wire harness main body, and the covering portion is preferably provided at an end portion in the length direction of the second path restricting member and covers the outer periphery of an end portion in the length direction of the first path restricting member.

[0019] According to the same configuration, since the covering portion is provided at an end portion in the length direction of the second path restricting member and covers the outer periphery of an end portion in the length direction of the first path restricting member, the first path restricting member and the second path restricting member are connected in the length direction. Therefore, the path of the wire harness main body is continuously restricted by the first path restricting member and the second path restricting member.

[0020] [9] The first path restricting member preferably restricts the path of a straight portion that is a straight-line portion in the path of the wire harness main body, and the second path restricting member preferably restricts the path of a bent portion that is a bent portion in the path of the wire harness main body.

[0021] According to the same 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, the path of the straight portion and the path of the bent portion of the wire harness are continuously suppressed from deviating from the desired paths.

[0022] [Details of Embodiments of the Present Disclosure] A specific example of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, a part of the configuration may be exaggerated or simplified. Also, the dimensional ratios of each part may differ in each drawing. In the present specification, "parallel" and "orthogonal" include not only the cases of strict parallelism and orthogonality, but also the cases that are generally parallel and orthogonal within the scope where the effects of the present embodiment are achieved. Note that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0023] (Overall configuration of wire harness 10) The wire harness 10 shown in FIG. 1 is mounted on a vehicle V such as a hybrid vehicle or an electric vehicle, for example. The wire harness 10 electrically connects two or more in-vehicle devices. 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 part of the vehicle V and a high-voltage battery M2 installed behind the inverter M1 in the vehicle V. The wire harness 10 is formed in a long shape so as to extend in the front-rear direction of the vehicle V, for example. The wire harness 10 is routed in the vehicle V such that an intermediate portion in the length direction of the wire harness 10 passes through the outside of the vehicle such as under the floor of the vehicle V, for example.

[0024] The inverter M1 is connected to, for example, a motor (not shown) for driving wheels that serves as a power source for vehicle travel. The inverter M1 generates AC power from the DC power of the high-voltage battery M2 and supplies the AC power to the motor. The high-voltage battery M2 is a battery that can supply a voltage of several hundred volts, for example.

[0025] The wire harness 10 has a wire harness body 11. The wire harness body 11 has a wire member 20 and a cylindrical outer member 30 that covers the outer periphery of the wire member 20. The wire harness 10 has connectors C1 and C2 attached to both ends of the wire member 20. One end in the length direction of the wire member 20 is connected to the inverter M1 via the connector C1, and the other end in the length direction of the wire member 20 is connected to the high-voltage battery M2 via the connector C2.

[0026] As shown in FIGS. 2 and 3, the wire harness 10 has a first path restricting member 40 attached to the outer periphery of the outer member 30 and a second path restricting member 60 as an attachment member attached to the outer periphery of the outer member 30. The first path restricting member 40 and the second path restricting member 60 restrict the routing path of the wire harness body 11. In FIG. 1, the illustration of the first path restricting member 40 and the second path restricting member 60 is omitted.

[0027] (Configuration of the wire member 20) As shown in FIGS. 4 and 5, the wire member 20 is, for example, one or a plurality of wires. In this embodiment, the wire member 20 has two wires 21 and a braided member 25 that collectively surrounds the outer peripheries of the plurality of wires 21.

[0028] As shown in FIG. 5, each wire 21 is a coated wire having a conductive core wire 22 and an insulating coating 23 that surrounds the outer periphery of the core wire 22 and has insulating properties. Each wire 21 is, for example, a high-voltage wire capable of handling high voltage and large current. Each wire 21 may be, for example, a non-shielded wire that does not have an electromagnetic shielding structure by itself, or a shielded wire that has an electromagnetic shielding structure by itself. Each wire 21 in this embodiment is a non-shielded wire.

[0029] As the core wire 22, for example, a stranded wire formed by twisting a plurality of metal strands, a single-core wire made of a single conductor, or the like can be used. As the single-core wire, for example, a columnar conductor composed of a single columnar metal bar having a solid structure inside, a cylindrical conductor having a hollow structure inside, or the like can be used. As the core wire 22, a combination of a stranded wire, a columnar conductor, and a cylindrical conductor may be used. As the material of the core wire 22, for example, a metal material such as a copper-based or aluminum-based material can be used.

[0030] The insulating coating 23 covers, for example, the outer peripheral surface of the core wire 22 over the entire circumference in the circumferential direction. The insulating coating 23 is composed of, for example, a resin material having insulating properties. The cross-sectional shape obtained by cutting the electric wire 21 by a plane orthogonal to the length direction of each electric wire 21, that is, the cross-sectional shape of each electric wire 21, can be formed into an arbitrary shape. The cross-sectional shape of each electric wire 21 is formed into, for example, a circular shape, a semi-circular shape, a polygonal shape, a square shape, a flat shape, or the like. The cross-sectional shape of each electric wire 21 in the present embodiment is formed into a circular shape.

[0031] The braided member 25 has, for example, a cylindrical shape that collectively surrounds the outer peripheries of a plurality of electric wires 21 as a whole. As the braided member 25, for example, a braided wire formed by braiding a plurality of metal strands, or a braided wire formed by combining a metal strand and a resin strand can be used. As the material of the metal strand, for example, a metal material such as a copper-based or aluminum-based material can be used. Although not shown, both ends in the length direction of the braided member 25 are grounded, for example, at connectors C1, C2 (see FIG. 1).

[0032] (Configuration of the exterior member 30) As shown in FIG. 4, the exterior member 30 has a cylindrical shape that surrounds the outer periphery of the wire member 20 over the entire circumference in the circumferential direction. The exterior member 30 in the present embodiment is formed into a cylindrical shape. The exterior member 30 has, for example, a continuous peripheral wall formed over the entire circumference in the circumferential direction of the exterior member 30. The exterior member 30 seals, for example, the inside of the exterior member 30 over the entire circumference in the circumferential direction. The exterior member 30 has, for example, a function of protecting the wire member 20 from flying objects and water droplets.

[0033] The exterior member 30 has flexibility, for example, and can be easily bent. Examples of the flexible exterior member 30 include, for example, a resin corrugated tube and a rubber waterproof cover. The exterior member 30 of the present embodiment is a resin corrugated tube having a bellows shape in which the diameter repeats in a large and small manner in the length direction of the exterior member 30. That is, the exterior member 30 of the present embodiment has a bellows structure in which the large-diameter portions 31 and the small-diameter portions 32 having a smaller diameter than the large-diameter portions 31 are alternately connected along the length direction of the exterior member 30. Each of the large-diameter portion 31 and the small-diameter portion 32 forms an annular shape that wraps around once along the circumferential direction of the exterior member 30, for example. As the material of the exterior member 30, for example, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used. In FIGS. 1 to 3, for the sake of simplifying the drawing, the exterior member 30 is shown in a simplified manner.

[0034] (Configuration of the first path restricting member 40 and the second path restricting member 60) As shown in FIGS. 2 and 3, each of the first path restricting member 40 and the second path restricting member 60 holds the exterior member 30. Each of the first path restricting member 40 and the second path restricting member 60 is harder than the exterior member 30, for example. Each of the first path restricting member 40 and the second path restricting member 60 has a hardness that is difficult to bend in a direction orthogonal to the length direction of the wire harness main body 11 compared to the exterior member 30. Thereby, each of the first path restricting member 40 and the second path restricting member 60 restricts the path of the wire harness main body 11. For example, each of the first path restricting member 40 and the second path restricting member 60 assists the exterior member 30 so that the wire harness main body 11 does not deviate from a desired path due to its own weight or the like and bend.

[0035] As shown in FIG. 2, the first path restricting member 40 is partially provided in the longitudinal direction of the wire harness main body 11. The first path restricting member 40 is attached to the outer periphery of the exterior member 30, for example, at a straight portion 11A that is a straight-line portion among the paths of the wire harness main body 11. The first path restricting member 40 restricts 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 a plurality of first path restricting members 40 are provided according to the path of the wire harness main body 11.

[0036] The second path restricting member 60 is partially provided in the longitudinal direction of the wire harness main body 11. The second path restricting member 60 is attached to the outer periphery of the exterior member 30, for example, at a bent portion 11B that is a bent portion among the paths of the wire harness main body 11. The second path restricting member 60 restricts 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 bends so as to deviate from a straight line. Note that one or a plurality of second path restricting members 60 are provided according to the path of the wire harness main body 11.

[0037] (Configuration of the first path restricting member 40) As shown in FIG. 5, the first path regulating member 40 covers a part in the circumferential direction of the outer periphery of the exterior member 30 among the outer periphery of the exterior member 30. The first path regulating member 40 has a shape that covers the outer periphery of the exterior member 30 at a part in the circumferential direction of the exterior member 30. The cross-sectional shape of the first path regulating member 40 is generally C-shaped as a whole. 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 a range larger than half of the entire circumference in the circumferential direction of 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 in the length direction of the first path regulating member 40.

[0038] The first path regulating member 40 is made of, for example, metal or resin. The first path regulating member 40 of the present embodiment is made of resin. As the material of the first path regulating member 40, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used. The first path regulating member 40 can be manufactured by well-known manufacturing methods such as extrusion molding and injection molding. In the present embodiment, the first path regulating member 40 is an extruded product manufactured by extrusion molding. Therefore, by using an extrusion molding machine that extrudes the raw material of the first path regulating member 40 in the length direction, the first path regulating member 40 can be easily manufactured. Also, by using a single extrusion molding machine, a plurality of types of the first path regulating member 40 having different dimensions in the length direction can be manufactured. For example, by cutting the base material of the first path regulating member 40 formed by a single extrusion molding machine to an arbitrary length using a cutting machine, a plurality of types of the first path regulating member 40 having different dimensions in the length direction can be manufactured.

[0039] The first path regulating member 40 has an insertion port 40X that opens in a direction orthogonal to the length direction of the first path regulating member 40. The insertion port 40X extends over the entire length direction of the first path regulating member 40. The first path regulating member 40 has a first end portion 41 and a second end portion 42 that are both end portions in the circumferential direction of the first path regulating member 40 and form the insertion port 40X. The first path regulating member 40 has a connecting portion 43 that connects the first end portion 41 and the second end portion 42. In other words, the first path regulating member 40 has a connecting portion 43 formed to cover a part of the circumferential direction of the exterior member 30, a first end portion 41 and a second end portion 42 provided at both ends of the connecting portion 43, and an insertion port 40X formed by the first end portion 41 and the second end portion 42.

[0040] As shown in FIG. 5, the connecting portion 43 constitutes the main part 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 formed, for example, in a shape along 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 formed in an arc shape, for example.

[0041] The first end portion 41 and the second end portion 42 are provided on opposite sides of each other in the circumferential direction of the first path regulating member 40. The first end portion 41 and the second end portion 42 are provided apart from each other with the insertion port 40X therebetween in the circumferential direction of the first path regulating member 40. In other words, a gap between the first end portion 41 and the second end portion 42 in the circumferential direction of the first path regulating member 40 is configured as the insertion port 40X. Thus, the first path regulating member 40 is formed in a C shape having the insertion port 40X in a part of the circumferential direction of the first path regulating member 40.

[0042] The cross-sectional shapes of the tips of the first end portion 41 and the second end portion 42 are formed in a curved shape. The cross-sectional shapes of the tips of the first end portion 41 and the second end portion 42 in the present embodiment are formed in an arc shape.

[0043] The first path restricting 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 restricting 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 the present embodiment is formed in an arc shape.

[0044] As shown in FIG. 3, each of the protruding portions 45, 46 extends in the longitudinal direction of the first path restricting member 40. Each of the protruding portions 45, 46 extends, for example, over the entire length in the longitudinal direction of the first path restricting member 40.

[0045] Each of the protruding portions 45, 46 presses the exterior member 30 from the outside of the exterior member 30. The exterior member 30 is elastically sandwiched between the protruding portion 45, the protruding portion 46, and the connecting portion 43. Thereby, the connection of the first path restricting member 40 to the exterior member 30 becomes strong.

[0046] As shown in FIG. 5, the opening width of the insertion port 40X, that is, the shortest distance between the first end portion 41 and the second end portion 42, is smaller than the outer diameter of the exterior member 30. The opening width of the insertion port 40X becomes larger when the first path restricting member 40 elastically deforms. For example, the opening width of the insertion port 40X becomes larger when the exterior member 30 is inserted into the insertion port 40X from a direction orthogonal to the longitudinal direction of the first path restricting member 40. When the exterior member 30 is inserted inside the first path restricting member 40, the first path restricting member 40 elastically returns to its original shape. As a result, since the opening width of the insertion port 40X is smaller than the outer diameter of the exterior member 30, the first path restricting member 40 is attached to the outer periphery of the exterior member 30.

[0047] (Configuration of the second path restricting member 60) As shown in FIG. 2, the second path restricting member 60 is attached to the outer periphery of a part of the first path restricting member 40 in the longitudinal direction. The second path restricting member 60 is attached to the outer periphery of the end portion of the first path restricting member 40 in the longitudinal direction. Further, the second path restricting member 60 is attached to the outer periphery of the exterior member 30 at the bent portion 11B. The second path restricting member 60 extends along the longitudinal direction of the exterior member 30 at the bent portion 11B. The second path restricting member 60 is bent, for example, along the shape of the bent portion 11B.

[0048] The second path restricting member 60 includes a second path restricting main body 61 and a lid 62. The second path restricting member 60 is made of, for example, metal or resin. The second path restricting member 60 of the present embodiment is made of resin. As the material of the second path restricting member 60, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used. The second path restricting member 60 can be manufactured by a well-known manufacturing method such as injection molding.

[0049] The second path restricting main body 61 includes a main body portion 64 and a receiving portion 65. In the present embodiment, the receiving portion 65 and the lid 62 constitute a covering portion 66. 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 generally semi-cylindrical 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 longitudinal 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.

[0050] The receiving part 65 is provided at the longitudinal end of the second path restricting member 60 and at the longitudinal end of the main body part 64. The receiving part 65 covers a part of the circumferential direction of the outer periphery of the first path restricting member 40. The receiving part 65 covers a part of the circumferential direction at the longitudinal end of the first path restricting member 40. The receiving part 65 has a shape that covers the outer periphery of the first path restricting member 40 in a part of the circumferential direction. The cross-sectional shape of the receiving part 65 is generally a semi-cylindrical shape as a whole. The receiving part 65 has a semi-cylindrical shape with a larger diameter than the main body part 64. The receiving part 65 covers half of the outer periphery of the first path restricting member 40.

[0051] The receiving part 65 and the lid 62 are integrally molded products made of the same material. That is, the second path restricting member 60 of the present embodiment is an integrally molded product in which the entire part including the second path restricting main body 61 and the lid 62 is made of the same material. The lid 62 is connected to the receiving part 65 via a thin hinge part 67. Specifically, the other end in the circumferential direction of the lid 62 is connected to one end in the circumferential direction of the receiving part 65 via a thin hinge part 67. The lid 62 is rotatable about the hinge part 67 with respect to the receiving part 65. The covering part 66 is deformable between a closed state in which the receiving part 65 and the lid 62 are closed and an open state in which the receiving part 65 and the lid 62 are open. The covering part 66 covers the outer periphery of the first path restricting member 40 in the closed state.

[0052] The lid 62 has a claw part 68. Further, the receiving part 65 has an engaged part 69 with which the claw part 68 can engage. Specifically, the engaged part 69 is provided at the other end in the circumferential direction of the receiving part 65. The claw part 68 is provided at one end in the circumferential direction of the lid 62. The claw part 68 engages with the engaged part 69 when the covering part 66 is in the closed state. The lid 62 is fixed so as not to be rotatable with respect to the receiving part 65 when the claw part 68 engages with the engaged part 69. Specifically, the receiving part 65 and the lid 62 cannot relatively rotate when the claw part 68 engages with the engaged part 69, and the covering part 66 is maintained in the closed state.

[0053] The lid 62 covers the entire circumference of the first path restricting member 40 together with the receiving portion 65. Specifically, when the covering portion 66 is in the closed state, the lid 62 covers the entire circumferential direction along the outer circumference of the first path restricting member 40 together with the receiving portion 65. The lid 62 of the present embodiment covers a part of the outer circumference of the first path restricting member 40 and a portion exposed from the insertion port 40X on the outer circumference of the exterior member 30. The cross-sectional shape of the lid 62 is generally semi-cylindrical. The lid 62 has a semi-cylindrical shape with the same diameter as that of the receiving portion 65. The lid 62 covers a portion that is not covered by the receiving portion 65 in the circumferential direction along the outer circumference of the first path restricting member 40 and covers half of the circumferential direction along the outer circumference of the first path restricting member 40.

[0054] As shown in FIG. 5, the second path restricting member 60 has elastic portions 70, 71 that are arranged in a compressed state between the covering portion 66 and at least one of the first path restricting member 40 and the exterior member 30.

[0055] More specifically, a plurality of elastic portions 70, 71 are provided in the circumferential direction of the covering portion 66. Two elastic portions 70, 71 are provided. One elastic portion 70 is provided on the receiving portion 65. The other elastic portion 71 is provided on the lid 62. The elastic portions 70, 71 are provided at intervals of 180° in the circumferential direction of the covering portion 66. One elastic portion 70 is provided at the center in the circumferential direction of the receiving portion 65. The other elastic portion 71 is provided at the center in the circumferential direction of the lid 62. As shown in FIG. 4, the elastic portions 70, 71 are provided at the center in the longitudinal direction of the covering portion 66. The elastic portions 70, 71 are integrally formed products made of the same material as the covering portion 66, that is, the receiving portion 65 and the lid 62.

[0056] One of the elastic parts 70 is a pair of elastic pieces that extend from the circumferential center to both circumferential end sides on the inner surface of the receiving part 65 while protruding radially inward of the receiving part 65. The other elastic part 71 is a pair of elastic pieces that extend from the circumferential center to both circumferential end sides on the inner surface of the lid 62 while protruding radially inward of the lid 62. Further, the elastic parts 70 and 71 are shaped such that the thickness becomes thinner toward the protruding tip. One of the elastic parts 70 and the other elastic part 71 have the same shape in a no-load state and in a state where they are not bent. Note that the receiving part 65 and the lid 62 have die-cut holes 72 at positions corresponding to the elastic parts 70 and 71, and manufacturing using a mold is facilitated.

[0057] Also, the other elastic part 71 constitutes a rotation prevention part that prevents the circumferential relative rotation of the first path restricting member 40 with respect to the covering part 66 by engaging with the insertion port 40X in the circumferential direction in the first path restricting member 40. When the covering part 66 is changed from the open state to the closed state, the other elastic part 71 moves until the tip reaches the insertion port 40X along the outer periphery of the exterior member 30, and thus engages with the insertion port 40X in the circumferential direction in the first path restricting member 40. Note that when the tip of the other elastic part 71 engages with the insertion port 40X, it becomes difficult to bend further. Therefore, in the closed state of the covering part 66, one of the elastic parts 70 bends more than the other elastic part 71. In the closed state of the covering part 66, one of the elastic parts 70 is disposed in a compressed state between the receiving part 65 and the first path restricting member 40. In the closed state of the covering part 66, the other elastic part 71 is disposed in a compressed state between the lid 62 and the exterior member 30.

[0058] Further, as shown in FIG. 2, the wire harness 10 has, for example, a slide restricting member 73 that restricts the slide movement of the first path restricting member 40 with respect to the longitudinal direction of the exterior member 30. The wire harness 10 has, for example, a slide restricting member 74 that restricts the slide movement of the second path restricting member 60 with respect to the longitudinal direction of the exterior member 30. As the slide restricting members 73 and 74, for example, resin or metal binding bands, caulking rings, adhesive tapes, etc. can be used. The slide restricting members 73 and 74 of the present embodiment are adhesive tapes. The slide restricting member 73 is wound around the end of the first path restricting member 40 on the side not connected to the second path restricting member 60 and the exterior member 30. The slide restricting member 74 is wound around the end of the second path restricting member 60 on the side not connected to the first path restricting member 40 and the exterior member 30.

[0059] Next, the operation of the present embodiment will be described. Elastic portions 70 and 71 are arranged in a compressed state between the covering portion 66 of the second path restricting member 60 and at least one of the first path restricting member 40 and the exterior member 30. Therefore, the receiving portion 65 and the lid 62 that constitute the covering portion 66 maintain a state of sandwiching the first path restricting member 40. Therefore, the state in which the first path restricting member 40 and the second path restricting member 60 are connected is maintained. Therefore, the path of the wire harness main body 11 is continuously restricted.

[0060] Next, the effects of the above embodiment will be described below. (1) It has elastic parts 70, 71 arranged in a compressed state between a covering part 66 that covers the outer periphery of the first path regulating member 40 and at least one of the first path regulating member 40 and the exterior member 30. Therefore, the first path regulating member 40 is held by the covering part 66 while being pressed by the elastic parts 70, 71. By doing so, for example, compared to a configuration where the lid 62 is integrally formed with the receiving part 65 via a thin hinge part 67 and the lid 62 is locked to the receiving part 65 by the engagement of the claw part 68 in the closed state, rattling between the covering part 66 and the first path regulating member 40 is suppressed. That is, in a configuration having a thin hinge part 67 and a claw part 68, rattling occurs between the receiving part 65 and the lid 62 at each part of the hinge part 67 and the claw part 68, and as a result, rattling between the covering part 66 and the first path regulating member 40 is likely to occur, but this can be avoided. Therefore, rattling between the first path regulating member 40 and the second path regulating member 60 can be suppressed. As a result, for example, breakage of the attachment site between the first path regulating member 40 and the second path regulating member 60 can be suppressed, and thus the path of the wire harness main body 11 can be stably regulated.

[0061] (2) Since a plurality of elastic parts 70, 71 are provided in the circumferential direction in the covering part 66, the first path regulating member 40 is held by the covering part 66 while being pressed at a plurality of locations by the elastic parts 70, 71. Therefore, for example, rattling between the first path regulating member 40 and the second path regulating member 60 can be further suppressed.

[0062] (3) Since the elastic parts 70, 71 are integrally formed products made of the same material as the covering part 66, an increase in the number of parts can be suppressed and they can be easily manufactured. (4) Since the elastic part 71 constitutes an anti-rotation part, relative rotation of the first path regulating member 40 in the circumferential direction with respect to the covering part 66 is blocked.

[0063] (5) Since the covering part 66 has a configuration having a receiving part 65 and a lid 62, for example, the covering part 66 can be retrofitted to the first path regulating member 40. Thereby, for example, compared to a case where the covering part 66 is a non-deformable cylindrical shape, the assembly workability of the wire harness 10 is improved.

[0064] (6) The attachment member attached to the first path restricting member 40 is a second path restricting member 60 attached to the outer periphery of the exterior member 30 and restricting the path of the wire harness main body 11. And the covering portion 66 is provided at the longitudinal end portion of the second path restricting member 60 to cover the outer periphery of the longitudinal end portion of the first path restricting member 40, so that the first path restricting member 40 and the second path restricting member 60 are connected in the longitudinal direction. Therefore, the path of the wire harness main body 11 is continuously restricted by the first path restricting member 40 and the second path restricting member 60.

[0065] (7) 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. Thereby, the path of the straight portion 11A and the path of the bent portion 11B of the wire harness main body 11 are continuously suppressed from deviating from the desired paths respectively.

[0066] (Other embodiments) The above embodiment can be implemented with the following modifications. The above embodiment and the following modification examples can be implemented in combination with each other within a technically non - conflicting range.

[0067] · In the above embodiment, the elastic portions 70, 71 are a pair of elastic pieces protruding radially inward of the covering portion 66, but they may be changed to other shapes. For example, as shown in FIG. 6, it may be modified. One elastic part 80 in this example is made thinner than other parts of the receiving part 65 and protrudes while curving from the circumferential center in the receiving part 65 toward the radially inner side of the receiving part 65. Further, the other elastic part 81 in this example is made thinner than other parts of the lid 62 and protrudes while curving from the circumferential center in the lid 62 toward the radially inner side of the lid 62. The one elastic part 80 and the other elastic part 81 have the same shape in a state of no load and not being deflected. The receiving part 65 and the lid 62 have die-cut holes 82 at positions corresponding to the elastic parts 80 and 81, and are made easy to manufacture using a mold. And the one elastic part 80 is arranged in a compressed state between the receiving part 65 and the first path restricting member 40. The other elastic part 81 is arranged in a compressed state between the lid 62 and the exterior member 30. Even in this way, rattling between the first path restricting member 40 and the second path restricting member 60 can be suppressed.

[0068] ·In the above embodiment, the elastic parts 70 and 71 are integrally formed products made of the same material as the covering part 66, but the present invention is not limited to this. For example, they may be made of a material different from the covering part 66 or may be separate bodies.

[0069] For example, as shown in FIG. 7, it may be changed. The elastic portion 83 in this example is made of metal. The elastic portion 83 can be elastically deformed into either a first state P1 that is bent so as to protrude radially outward of the covering portion 66 or a second state P2 that is bent so as to protrude radially inward of the covering portion 66, and is a metal plate that maintains either state. That is, when an external force is applied radially outward of the covering portion 66 in the second state P2, the elastic portion 83 is bent into the first state P1 that protrudes radially outward of the covering portion 66 and that state is maintained. Further, when an external force is applied radially inward of the covering portion 66 in the first state P1, the elastic portion 83 is bent into the second state P2 that protrudes radially inward of the covering portion 66 and that state is maintained. The elastic portion 83 is, for example, in the first state P1 when the covering portion 66 is in the open state, and is in the second state P2 after the covering portion 66 is closed. Thereby, the elastic portion 83 is arranged in a compressed state between the covering portion 66 and at least one of the first path restricting member 40 and the exterior member 30 in the second state P2. The elastic portion 83 in this example is provided on the lid 62 and is arranged in a compressed state between the covering portion 66 and the exterior member 30. Further, the elastic portion 83 in this example is insert-molded into the lid 62 such that both ends are embedded in the lid 62.

[0070] By doing so, since the elastic portion 83 is made of metal, for example, it becomes possible to strongly press at least one of the first path restricting member 40 and the exterior member 30. Further, for example, it can be manufactured by elastically deforming the elastic portion 83 from the first state P1 to the second state P2 after arranging the first path restricting member 40 inside the covering portion 66, and the manufacture of the wire harness 10 becomes easy.

[0071] Also, for example, as shown in FIG. 8, it may be changed. The elastic parts 84 and 85 in this example are made of rubber. One elastic part 84 in this example is interposed between the receiving part 65 and the first path restricting member 40 and is arranged in a compressed state. The other elastic part 85 in this example is interposed between the lid 62 and the exterior member 30 and is arranged in a compressed state. Even in this case, rattling between the first path restricting member 40 and the second path restricting member 60 can be suppressed. Note that the elastic parts 84 and 85 may be changed to, for example, a metal leaf spring, a compression coil spring, or the like.

[0072] ·In the above embodiment, it is assumed that two elastic parts 70 and 71 are provided in the circumferential direction in the covering part 66, but the present invention is not limited to this, and the configuration may be changed to one or three or more provided.

[0073] ·In the above embodiment, it is assumed that the elastic part 71 constitutes a locking part that engages with the insertion port 40X in the circumferential direction of the first path restricting member 40, but the present invention is not limited to this, and the configuration may be such that it does not engage with the insertion port 40X.

[0074] ·In the above embodiment, it is assumed that the covering part 66 has a configuration having the receiving part 65 and the lid 62, but the present invention is not limited to this, and for example, the covering part 66 may be changed to a cylindrical configuration that cannot be disassembled or deformed. Further, the receiving part 65 and the lid 62 are configured such that the lid 62 is integrally formed with the receiving part 65 via a thin hinge part 67 and the lid 62 is locked to the receiving part 65 by the engagement of the claw part 68 in the closed state, but the receiving part 65 and the lid 62 fixed by other structures may be changed.

[0075] ·The second path restricting member 60 in the above embodiment is formed to restrict the path of the bent part 11B of the wire harness main body 11, but the present invention is not limited to this. For example, the second path restricting member 60 may be changed to a shape that restricts the path of the straight part 11A of the wire harness main body 11. In this case, the second path restricting member 60 is changed to, for example, a shape in which the bent shape in the main body part 64 extends linearly.

[0076] ·In the above embodiment, the attachment member attached to the first path restricting member 40 is embodied as the second path restricting 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 restricting member 40 to the vehicle V.

[0077] ·The structure of the first path restricting member 40 of the above embodiment can be appropriately changed. For example, the first path restricting member 40 has an insertion port 40X and is not particularly limited as long as it has a structure that can be attached to the outer periphery of the exterior member 30.

[0078] ·The protruding portion 45 of the above embodiment may be provided at a position farther from the insertion port 40X than the tip of the first end portion 41 in the circumferential direction of the first path restricting member 40. ·The protruding portion 46 of the above embodiment may be provided at a position farther from the insertion port 40X than the tip of the second end portion 42 in the circumferential direction of the first path restricting member 40.

[0079] ·The protruding portions 45 and 46 of the above embodiment may be partially provided in the longitudinal direction of the first path restricting member 40. ·At least one of the protruding portions 45 and 46 of the above embodiment may be omitted.

[0080] ·In the first path restricting member 40 of the above embodiment, the radial thickness of the connecting portion 43 may be configured to change in the circumferential direction. ·The shape of the connecting portion 43 in the first path restricting member 40 of the above embodiment is not limited to an arc shape, and can be changed to, for example, an elliptical arc shape or a U shape.

[0081] ·In the above embodiment, the first path restricting member 40 and the second path restricting member 60 are assumed to be harder than the exterior member 30, but are not limited thereto, and may have the same or lower hardness than the exterior member 30. That is, the first path restricting member 40 and the second path restricting member 60 may act so that the wire harness main body 11 is less likely to bend than the wire harness main body 11 in a state where the first path restricting member 40 and the second path restricting member 60 are not attached.
