Summary of the Invention

Problems to be Solved by the Invention

[0004] In the wire harness as described above, the path restricting member is attached to the outer periphery of the exterior member covering the wire member, and further, the holding portion of the clamp is attached so as to cover the entire circumference of the path restricting member. For this reason, there is a problem that the outer shape of the wire harness becomes large in the radial direction at the attachment position of the clamp.

[0005] An object of the present disclosure is to provide a wire harness that enables miniaturization in the radial direction at the attachment position of the fixing member.

Means for Solving the Problems

[0006] The wire harness of the present disclosure includes a wire harness body having a wire member and an exterior member covering the outer periphery of the wire member, a first path restricting member attached to the outer periphery of the exterior member for restricting the path of the wire harness body, and a fixing member for fixing the first path restricting member to an attachment target. The first path restricting member has an insertion port that opens in a direction orthogonal to the length direction of the first path restricting member and extends over the entire length direction of the first path restricting member, and a first connecting portion provided partially in the circumferential direction of the first path restricting member. The fixing member has a fixing portion fixed to the attachment target and a second connecting portion connected to the first connecting portion. [Effects of the Invention]

[0009] [Description of 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 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 a fixing member for fixing the first path regulating member to an attachment target, 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 a first connecting portion provided partially in the circumferential direction of the first path regulating member, and the fixing member has a fixing portion fixed to the attachment target and a second connecting portion connected to the first connecting portion.

[0010] According to this configuration, the second connecting portion of the fixing member is connected to the first connecting portion provided partially in the circumferential direction of the first path regulating member. Therefore, it is not necessary to cover the entire circumference of the first path regulating member with the second connecting portion. Accordingly, it is possible to reduce the size in the radial direction at the attachment location of the fixing member.

[0011] [2] One of the first connecting portion and the second connecting portion is a concave portion, and the other of the first connecting portion and the second connecting portion is a convex portion that fits into the concave portion. According to this configuration, it is possible to connect the first connecting portion and the second connecting portion with a simple configuration.

[0012] [3] The cross-sectional shape orthogonal to the length direction of the first path regulating member is uniform over the entire length in the length direction of the first path regulating member, and the first connecting portion is provided over the entire length in the length direction of the first path regulating member.

[0013] According to this configuration, the first path regulating member can be formed by extrusion molding. Therefore, the first path regulating member can be easily manufactured, contributing to cost reduction. Note that the concave or convex shape of the first connecting portion of the first path regulating member also has a uniform cross-sectional shape in the length direction of the first path regulating member.

[0014] [4] The second connecting portion can be attached to the first connecting portion along the length direction of the first path restricting member from the end portion of the first connecting portion in the length direction of the first path restricting member. According to this configuration, it becomes possible to attach the second connecting portion to the first connecting portion in the length direction of the first path restricting member. As a result, the fixing member can be easily attached to the first path restricting member.

[0015] [5] The second connecting portion is connected to the first connecting portion so as to be movable in the length direction of the first path restricting member, and at least one of both end portions in the length direction of the first path restricting member is provided with a movement restricting portion that restricts the movement of the second connecting portion in the length direction of the first path restricting member.

[0016] According to this configuration, it becomes possible to suppress the fixing member from coming off the first path restricting member by the movement restricting portion. [6] The wire harness is attached to the outer periphery of the exterior member and includes a second path restricting member that restricts the path of the wire harness main body. The second path restricting member has a covering connecting portion that is connected in a manner of covering the outer periphery with respect to the end portion in the length direction of the first path restricting member, and the covering connecting portion functions as the movement restricting portion.

[0017] According to this configuration, the first path restricting member and the second path restricting member are connected in the length direction at the covering connecting portion. Therefore, the path of the wire harness main body is continuously restricted by the first path restricting member and the second path restricting member. Further, since the covering connecting portion also serves as a movement restricting portion that restricts the movement of the second connecting portion, the configuration can be simplified.

[0018] [7] The first path restricting member 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 restricts the path of a bent portion that is a bent portion in the path of the wire harness main body.

[0019] According to this configuration, the path of the straight portion is restricted by the first path restricting member, and the path of the bent portion is restricted by the second path restricting member. As a result, the paths of the straight portion and the bent portion of the wire harness main body are continuously suppressed from deviating from the desired paths respectively.

[0020] [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 shown in an exaggerated or simplified manner. Also, the dimensional ratios of each part may be different in each drawing. In addition, "orthogonal" in this specification includes not only the case of strict orthogonality but also the case of substantially orthogonality within the range where the actions and effects in the present embodiment are exhibited.

[0021] In addition, "opposing" in this specification means that surfaces or members are in a position facing each other, and includes not only the case where they are completely in a facing position but also the case where they are partially in a facing position. Also, "opposing" in this specification includes both the case where a member different from the two parts is interposed between the two parts and the case where nothing is interposed between the two parts.

[0022] In addition, the term "annular" used in the description of this specification may refer to any structure forming a loop, or a continuous shape without ends, and a generally loop-shaped structure having a gap such as a C shape. Note that the "annular" shape includes, but is not limited to, a circular shape, an elliptical shape, and a polygon having sharp or rounded corners.

[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. 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. The wire harness 10 is routed on the vehicle V such that, for example, 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.

[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, for example, several hundred volts.

[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 portion in the length direction of the wire member 20 is connected to the inverter M1 via the connector C1, and the other end portion 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 FIG. 2, the wire harness 10 has a first route restricting member 40 attached to the outer periphery of the outer member 30 and a second route restricting member 50 attached to the outer periphery of the outer member 30. The first route restricting member 40 and the second route restricting member 50 restrict the route along which the wire harness body 11 is routed. The wire harness 10 also includes a fixing member 60 for fixing the first route restricting member 40 to the vehicle V. In FIG. 1, the illustration of the first route restricting member 40, the second route restricting member 50, and the fixing member 60 is omitted.

[0027] (Configuration of the wire member 20) As shown in FIGS. 3 and 4, the wire member 20 includes, for example, one or a plurality of wires. In this embodiment, the wire member 20 includes two wires 21 and a braided member 25 that collectively surrounds the outer peripheries of the plurality of wires 21.

[0028] 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 or a single-core wire made of a single conductor can be used. As the single-core wire, for example, a columnar conductor made of a single columnar metal bar having a solid structure inside or a tubular conductor having a hollow structure inside can be used. As the core wire 22, a combination of a stranded wire, a columnar conductor, and a tubular 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 formed of, for example, a resin material having insulating properties. The cross-sectional shape of the wire 21 obtained by cutting the wire 21 by a plane orthogonal to the length direction of each wire 21, that is, the cross-sectional shape of each wire 21, can be formed into an arbitrary shape. The cross-sectional shape of each wire 21 is formed, for example, in 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 wire 21 in this embodiment is formed in a circular shape.

[0031] The braided member 25 has, for example, a cylindrical shape that collectively surrounds the outer circumferences 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 illustration is omitted, both end portions 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) The exterior member 30 has a cylindrical shape that surrounds the outer circumference of the wire member 20 over the entire circumference in the circumferential direction. The exterior member 30 of the present embodiment is formed in 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, for example, flexibility and can be easily bent. Examples of the exterior member 30 having flexibility 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 large-diameter portions 31 and small-diameter portions 32 having a smaller diameter than the large-diameter portions 31 are alternately provided along the length direction of the exterior member 30. Each of the large-diameter portion 31 and the small-diameter portion 32 has, for example, an annular shape that makes one turn along the circumferential direction of the exterior member 30. As the material of the exterior member 30, for example, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used. In FIG. 2, for the sake of simplification of 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 50) As shown in FIG. 2, each of the first path restricting member 40 and the second path restricting member 50 holds the exterior member 30. Each of the first path restricting member 40 and the second path restricting member 50 is, for example, harder than the exterior member 30. Each of the first path restricting member 40 and the second path restricting member 50 has a hardness that is difficult to bend in a direction orthogonal to the length direction of the wire harness main body 11 as compared with the exterior member 30. Thereby, each of the first path restricting member 40 and the second path restricting member 50 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 50 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] The first path restricting member 40 is partially provided in the length 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 linear portion of the path 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 more first path restricting members 40 are provided according to the path of the wire harness main body 11.

[0036] The second path restricting member 50 is partially provided in the length direction of the wire harness main body 11. The second path restricting member 50 is attached to the outer periphery of the exterior member 30, for example, at a bent portion 11B that is a bent portion of the path of the wire harness main body 11. The second path restricting member 50 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 more second path restricting members 50 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 FIGS. 3 and 4, the first path regulating member 40 covers a part of the outer circumference 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 circumference 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 as a whole. The first path regulating member 40 covers, for example, a range larger than half of the outer circumference of the exterior member 30. That is, the first path regulating member 40 covers a range larger than half of the entire outer circumference of the exterior member 30 in the circumferential direction of the exterior member 30.

[0038] 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.

[0039] 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, 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. Also, a plurality of types of the first path regulating members 40 having different dimensions in the length direction can be manufactured using a single extrusion molding machine. For example, a plurality of types of the first path regulating members 40 having different dimensions in the length direction can be manufactured 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.

[0040] As shown in FIGS. 3 and 4, 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.

[0041] 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, for example, formed 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, for example, formed in an arc shape.

[0042] The first end portion 41 and the second end portion 42 are provided on opposite sides 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.

[0043] 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.

[0044] 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 and 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 and 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 and 46 is formed, for example, in a curved shape. The cross-sectional shape of each of the protruding portions 45 and 46 in the present embodiment is formed in an arc shape. Each of the protruding portions 45 and 46 extends in the length direction of the first path regulating member 40. Each of the protruding portions 45 and 46 extends, for example, over the entire length in the length direction of the first path regulating member 40.

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

[0046] As shown in FIG. 4, 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 increases when the first path regulating member 40 elastically deforms. For example, the opening width of the insertion port 40X increases when the exterior member 30 is inserted into the insertion port 40X from a direction orthogonal to the length direction of the first path regulating member 40. When the exterior member 30 is inserted inside the first path regulating member 40, the first path regulating member 40 elastically returns to its original shape. Thereby, since the opening width of the insertion port 40X becomes smaller than the outer diameter of the exterior member 30, the first path regulating member 40 is attached to the outer periphery of the exterior member 30.

[0047] As shown in FIGS. 3 and 4, the first path regulating member 40 has a first connecting portion 47 at the connecting portion 43. The first connecting portion 47 is provided partially in the circumferential direction of the first path regulating member 40. Also, the first connecting portion 47 is provided over the entire length of the first path regulating member 40 in the longitudinal direction. A fixing member 60 is connected to the first connecting portion 47.

[0048] (Configuration of the second path regulating member 50) As shown in FIG. 2, the second path regulating member 50 is attached to the outer periphery of a part of the first path regulating member 40 in the longitudinal direction. The second path regulating member 50 is attached to the outer periphery at the end portion 40a of the first path regulating member 40 in the longitudinal direction. Also, the second path regulating member 50 is attached to the outer periphery of the exterior member 30 at the bent portion 11B. The second path regulating member 50 extends along the longitudinal direction of the exterior member 30 at the bent portion 11B. The second path regulating member 50 is bent, for example, along the shape of the bent portion 11B.

[0049] The second path regulating member 50 has a main body portion 51 and a lid portion 52. The second path regulating member 50 including the main body portion 51 and the lid portion 52 is made of, for example, metal or resin. The second path regulating member 50 of the present embodiment is made of resin. As the material of the second path regulating member 50, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used. The second path regulating member 50 can be manufactured by a well-known manufacturing method such as injection molding.

[0050] The main body portion 51 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 51 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 51 is generally semi-cylindrical as a whole. The main body portion 51 covers approximately half of the outer periphery of the exterior member 30. The main body portion 51 extends along the longitudinal direction of the exterior member 30 at the bent portion 11B. The main body portion 51 is bent along the shape of the bent portion 11B.

[0051] The second path regulating member 50 has a covering connection portion 53 including a lid portion 52 at one end in the length direction of the main body portion 51. The covering connection portion 53 is connected to the end portion 40a in the length direction of the first path regulating member 40. The covering connection portion 53 is composed of the end portion in the length direction of the main body portion 51 and the lid portion 52. The covering connection portion 53 forms an annular shape when viewed from the length direction of the wire harness main body 11. The covering connection portion 53 covers the entire circumference of the end portion 40a in the length direction of the first path regulating member 40 by the lid portion 52 and the end portion in the length direction of the main body portion 51.

[0052] The lid portion 52 is, for example, integrally formed with the main body portion 51. The lid portion 52 is connected to the main body portion 51 at a hinge portion 54, for example. The lid portion 52 is rotatable between an open position and a closed position covering the first path regulating member 40 and the exterior member 30 about the hinge portion 54 as an axis. Note that the lid portion 52 shown in FIG. 2 is in the closed position. Further, the lid portion 52 has a locking claw 55. The locking claw 55 is locked to a lock portion 56 provided on the main body portion 51 in a state where the lid portion 52 is in the closed position. Thereby, the lid portion 52 is held in the closed position.

[0053] As shown in FIG. 2, the wire harness 10 has, for example, a slide regulating member 90 that regulates the slide movement of the second path regulating member 50 with respect to the length direction of the exterior member 30. As the slide regulating member 90, for example, a resin or metal binding band, a caulking ring, an adhesive tape, or the like can be used. The slide regulating member 90 of the present embodiment is an adhesive tape. The slide regulating member 90 is wound around the end portion of the second path regulating member 50 on the side not connected to the first path regulating member 40 and the exterior member 30.

[0054] (Configuration of the fixing member 60) As shown in FIG. 4, the fixing member 60 fixes the first path restricting member 40 to the panel P that constitutes the floor portion of the vehicle V. The fixing member 60 is made of, for example, metal or resin. The fixing member 60 of the present embodiment is made of resin. As the material of the fixing member 60, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used. The fixing member 60 can be manufactured by a well-known manufacturing method such as injection molding. In the present embodiment, as an example, one fixing member 60 is provided on the first path restricting member 40, but a configuration in which a plurality of fixing members 60 are provided on the first path restricting member 40 may also be adopted.

[0055] As shown in FIGS. 3 and 4, the fixing member 60 has a fixing portion 61 fixed to the panel P and a second connecting portion 62 connected to the first connecting portion 47 of the first path restricting member 40. The fixing portion 61 has, as an example, a structure fixed to a bolt B extending from the panel P. The fixing portion 61 has an insertion hole 63 through which the bolt B is inserted. FIGS. 3 and 4 illustrate the width direction X, the depth direction Y, and the height direction Z as three directions orthogonal to each other in the fixing member 60. The bolt B is inserted along the height direction Z into the insertion hole 63.

[0056] The fixing portion 61 has a first side surface 61a facing the panel P in the mounted state on the vehicle V. The insertion hole 63 has an opening at one end side in the height direction Z on the first side surface 61a. That is, the insertion hole 63 has a bolt insertion port 64 into which the bolt B is inserted on the first side surface 61a. The insertion hole 63 of the present embodiment also has openings on both sides in the depth direction Y.

[0057] Inside the insertion hole 63, a locking portion 65 is provided that axially locks the bolt B inserted into the fixing portion 61 from the bolt insertion port 64. The locking portion 65 extends, for example, from a pair of inner wall surfaces facing each other in the width direction X in the insertion hole 63. A plurality of the locking portions 65 are arranged in parallel in the height direction Z, for example. The locking portion 65 is inclined, for example, toward the front side in the insertion direction of the bolt B as it extends inward from the pair of inner wall surfaces. The locking portion 65 is axially locked to the thread of the bolt B at its tip portion.

[0058] The fixing portion 61 has elastic pieces 66 on the first side surface 61a. The elastic pieces 66 are provided, for example, on both sides in the depth direction Y with respect to the insertion hole 63. The elastic pieces 66 elastically contact the panel P in the mounted state on the vehicle V. That is, the elastic pieces 66 apply an elastic force to the panel P. Thereby, rattling of the fixing member 60 can be suppressed.

[0059] (Configuration of the first connecting portion 47 and the second connecting portion 62) The second connecting portion 62 is, for example, a convex portion protruding from the second side surface 61b in the width direction X of the fixing portion 61. Note that the second connecting portion 62 of the present embodiment is integrally formed with the fixing portion 61.

[0060] The second connecting portion 62 has a base portion 71 extending along the width direction X from the second side surface 61b, and a pair of extending portions 72 extending bifurcated from the tip of the base portion 71. The pair of extending portions 72 extend from the base portion 71 to one side and the other side in the height direction Z, respectively. Thereby, the second connecting portion 62 has a substantially T-shaped cross-sectional shape perpendicular to the length direction of the first path regulating member 40. Further, the pair of extending portions 72, for example, have an arc-shaped cross-sectional shape perpendicular to the length direction of the first path regulating member 40 along the circumferential direction of the first path regulating member 40. Also, in the second connecting portion 62, the cross-sectional shape perpendicular to the length direction of the first path regulating member 40 is, for example, uniform in the length direction of the first path regulating member 40.

[0061] The first connecting portion 47 is a recess into which the second connecting portion 62 is fitted. The first connecting portion 47 is provided at a circumferential part of the connecting portion 43. In the connecting portion 43, the part facing the insertion port 40X is defined as the bottom portion 43a, and the parts from the bottom portion 43a to the first end portion 41 and from the bottom portion 43a to the second end portion 42 are each defined as the side portion 43b. The first connecting portion 47 is provided on one of the two side portions 43b.

[0062] In the first connecting portion 47, the cross-sectional shape perpendicular to the length direction of the first path restricting member 40 forms a substantially T shape similar to the cross-sectional shape of the second connecting portion 62. Specifically, the first connecting portion 47 has a first accommodating portion 81 in which the base portion 71 of the second connecting portion 62 is disposed, and a pair of second accommodating portions 82 in which the pair of extending portions 72 are respectively disposed. The first accommodating portion 81 extends from the outer peripheral surface of the connecting portion 43 into the connecting portion 43 along the radial direction of the first path restricting member 40. The pair of second accommodating portions 82 extend in opposite directions from the first accommodating portion 81 along the circumferential direction of the first path restricting member 40.

[0063] In the first connecting portion 47, the cross-sectional shape perpendicular to the length direction of the first path restricting member 40 is uniform in the length direction of the first path restricting member 40. The first connecting portion 47 is provided over the entire length in the length direction of the first path restricting member 40. That is, the first connecting portion 47 is open in the length direction of the first path restricting member 40 at both end faces in the length direction of the first path restricting member 40.

[0064] The second connecting portion 62 can be attached to the first connecting portion 47 along the length direction of the first path restricting member 40 from the opening at the end of the first connecting portion 47 in the length direction of the first path restricting member 40. And the second connecting portion 62 is movable in the length direction of the first path restricting member 40 in a state of being connected to the first connecting portion 47, that is, in a state where the base portion 71 and each extending portion 72 are respectively disposed in the first accommodating portion 81 and each second accommodating portion 82. Thereby, the attachment position of the fixing member 60 can be adjusted in the length direction of the first path restricting member 40.

[0065] As shown in FIG. 2, the covering connection portion 53 provided at the end portion 40a in the length direction of the first path regulating member 40 functions as a movement regulating portion that regulates the movement of the second connection portion 62 in the length direction of the first path regulating member 40. That is, the second connection portion 62 connected to the first connection portion 47 can abut against the covering connection portion 53 that covers the outer periphery of the end portion 40a of the first path regulating member 40 in the length direction of the first path regulating member 40. Thereby, the movement of the second connection portion 62 in one direction in the length direction of the first path regulating member 40 is regulated by the covering connection portion 53.

[0066] Further, in the first path regulating member 40, a movement regulating portion 91 that regulates the movement of the second connection portion 62 in the length direction of the first path regulating member 40 is attached to the end portion 40b on the side opposite to the end portion 40a. As the movement regulating portion 91, for example, a resin or metal binding band, a caulking ring, an adhesive tape, or the like can be used. The movement regulating portion 91 of the present embodiment is an adhesive tape. The movement regulating portion 91 is wound around the end portion 40b of the first path regulating member 40 and the exterior member 30.

[0067] The second connection portion 62 connected to the first connection portion 47 can abut against the movement regulating portion 91 wound around the outer periphery of the end portion 40b of the first path regulating member 40 in the length direction of the first path regulating member 40. Thereby, the movement of the second connection portion 62 in one direction in the length direction of the first path regulating member 40 is regulated by the movement regulating portion 91. Further, the movement regulating portion 91 also regulates the sliding movement of the first path regulating member 40 with respect to the length direction of the exterior member 30.

[0068] The effects of the present embodiment will be described. (1) The first path restricting member 40 has a first connecting portion 47 provided partially in the circumferential direction of the first path restricting member 40. The fixing member 60 has a fixing portion 61 fixed to the panel P and a second connecting portion 62 connected to the first connecting portion 47. According to this configuration, the second connecting portion 62 of the fixing member 60 is connected to the first connecting portion 47 provided partially in the circumferential direction of the first path restricting member 40. For this reason, it is not necessary to adopt a mode in which the second connecting portion 62 covers the entire circumference of the first path restricting member 40. Therefore, miniaturization in the radial direction at the attachment location of the fixing member 60 becomes possible.

[0069] (2) The first connecting portion 47 is a concave portion, and the second connecting portion 62 is a convex portion fitted to the first connecting portion 47. According to this configuration, it becomes possible to connect the first connecting portion 47 and the second connecting portion 62 with a simple configuration.

[0070] (3) The cross-sectional shape of the first path restricting member 40, that is, the cross-sectional shape orthogonal to the length direction, is uniform over the entire length in the length direction of the first path restricting member 40. And the first connecting portion 47 is provided over the entire length in the length direction of the first path restricting member 40. According to this configuration, the first path restricting member 40 can be formed by extrusion molding. Therefore, the first path restricting member 40 can be easily manufactured, contributing to cost reduction. Note that the concave or convex shape of the first connecting portion 47 of the first path restricting member 40 also has a uniform cross-sectional shape in the length direction of the first path restricting member 40.

[0071] (4) The second connecting portion 62 can be attached to the first connecting portion 47 along the length direction from the end portion of the first connecting portion 47 in the length direction of the first path restricting member 40. According to this configuration, it becomes possible to attach the fixing member 60 to the first connecting portion 47 in the length direction of the first path restricting member 40. As a result, the fixing member 60 can be easily attached to the first path restricting member 40.

[0072] (5) The second connecting part 62 is connected to the first connecting part 47 so as to be movable in the length direction of the first path restricting member 40. At the end part 40a in the length direction of the first path restricting member 40, a covering connecting part 53 is attached as a movement restricting part for restricting the movement of the second connecting part 62 in the length direction of the first path restricting member 40. Also, at the end part 40b in the length direction of the first path restricting member 40, a movement restricting part 91 is attached for restricting the movement of the second connecting part 62 in the length direction of the first path restricting member 40. According to this configuration, it is possible to suppress the second connecting part 62 from coming off from the end part in the length direction of the first connecting part 47 by the covering connecting part 53 and the movement restricting part 91.

[0073] (6) The wire harness 10 includes a second path restricting member 50 that is attached to the outer periphery of the exterior member 30 and restricts the path of the wire harness main body 11. The second path restricting member 50 has a covering connecting part 53 that is connected in a manner of covering the outer periphery with respect to the end part 40a in the length direction of the first path restricting member 40. And the covering connecting part 53 functions as a movement restricting part. According to this configuration, the first path restricting member 40 and the second path restricting member 50 are connected in the length direction by the covering connecting part 53. 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 50. Also, since the covering connecting part 53 also serves as a movement restricting part for restricting the movement of the second connecting part 62, simplification of the configuration is possible.

[0074] (7) The first path restricting member 40 restricts the path of a straight part 11A that is a straight part in the path of the wire harness main body 11. The second path restricting member 50 restricts the path of a bent part 11B that is a bent part in the path of the wire harness main body 11. According to this configuration, it is continuously suppressed that the path of the straight part 11A and the path of the bent part 11B of the wire harness main body 11 deviate from the desired paths respectively.

[0075] This embodiment can be implemented with the following modifications. This embodiment and the following modification examples can be implemented in combination with each other within a range where there is no technical contradiction. ·For example, as shown in FIG. 5, at the connecting portion 43 of the first path restricting member 40, the radial thickness of the portion 43x where the first connecting portion 47 is not provided may be formed to be thinner than the radial thickness of the portion 43y where the first connecting portion 47 is provided. According to such a configuration, it is possible to further contribute to the miniaturization in the radial direction at the mounting location of the fixing member 60.

[0076] ·In the above embodiment, there is one first connecting portion 47 and one second connecting portion 62 respectively, but it is not limited thereto, and a plurality of first connecting portions 47 and second connecting portions 62 may be provided respectively. For example, in the configuration shown in FIG. 6, there are two first connecting portions 47 and two second connecting portions 62 respectively. Each of the second connecting portions 62 having the same configuration is configured such that the extending portion 72 extending toward the adjacent second connecting portion 62 side among the pair of extending portions 72 is short. It is possible to suppress the range occupied by the second connecting portion 62 and the first connecting portion 47 in the circumferential direction of the first path restricting member 40 to be small.

[0077] ·The second connecting portion 62 of the above embodiment is configured to be attachable to the first connecting portion 47 along the length direction of the first path restricting member 40, but it is not limited thereto. For example, the second connecting portion 62 may be configured to be attachable to the first connecting portion 47 from the outside in the radial direction of the first path restricting member 40.

[0078] For example, in the configuration shown in FIG. 7, the second connecting portion 62 can be attached to the first connecting portion 47 from the outside in the radial direction of the first path restricting member 40. In this configuration, two first connecting portions 47 and two second connecting portions 62 are provided respectively. Each second connecting portion 62 has a first extending portion 73 and a second extending portion 74 that extend along the circumferential direction of the first path restricting member 40 from the tip of the base portion 71. The first extending portion 73 and the second extending portion 74 extend in opposite directions from the tip of the base portion 71. The first extending portion 73 is configured to be longer than the second extending portion 74 in the circumferential direction of the first path restricting member 40. And, on the inner circumferential side surface of the second extending portion 74, an inclined surface 75 is provided so that the thickness in the direction along the radial direction of the first path restricting member 40 becomes thinner toward the tip of the second extending portion 74. In this configuration, when assembling the second connecting portion 62 to the first connecting portion 47, first, from the outer peripheral side of the first path restricting member 40, the tip of the first extending portion 73 is inserted from the first accommodating portion 81 into the second accommodating portion 82. Then, the second extending portion 74 together with the base portion 71 is inserted into the first accommodating portion 81. Here, since the inclined surface 75 is formed on the second extending portion 74, it becomes easier to insert the second extending portion 74 into the inside of the first connecting portion 47. Also with such a configuration, since the second connecting portion 62 and the first connecting portion 47 are partially provided in the circumferential direction of the first path restricting member 40, it is possible to reduce the size in the radial direction at the attachment location of the fixing member 60.

[0079] ·In the first path restricting member 40 of the above embodiment, the first connecting portion 47 may be provided at the bottom 43a of the connecting portion 43. ·The concavo-convex relationship between the first connecting portion 47 and the second connecting portion 62 is not limited to the above embodiment. That is, the second connecting portion 62 may be a concave portion, and the first connecting portion 47 may be a convex portion that is fitted into the second connecting portion 62. Also with such a configuration, it is possible to connect the first connecting portion 47 and the second connecting portion 62 with a simple configuration.

[0080] ·In the above embodiment, second path restricting members 50 may be provided on both sides in the length direction of the first path restricting member 40. In this case, covering connecting portions 53 are attached to the respective end portions 40a, 40b in the length direction of the first path restricting member 40.

[0081] · As the covering connection part 53 and the movement restriction part 91 as the movement restriction parts, they are respectively configured to cover the outer circumferences of the end parts 40a and 40b of the first path restriction member 40, but it is not particularly limited thereto. As long as it is a configuration capable of restricting the movement of the second connection part 62 along the length direction of the first path restriction member 40, the movement restriction part may be provided partially in the circumferential direction of the first path restriction member 40. Further, in the above embodiment, a configuration may be adopted in which either one of the movement restriction part 91 and the covering connection part 53 is not attached to the first path restriction member 40.

[0082] · The fixing part 61 of the above embodiment was of the type fixed to the bolt B extending from the panel P, but it is not particularly limited thereto.

[0083] · The second path restriction member 50 of the above embodiment was formed to restrict the path of the bent part 11B of the wire harness main body 11, but it is not limited thereto.

In this case, the second path restriction member 50 is, for example, changed to a shape in which the bent shape in the main body part 51 extends linearly.

[0084] · The structure of the first path restriction member 40 of the above embodiment can be changed as appropriate. For example, if the first path restriction member 40 has an insertion port 40X and has a structure that can be attached to the outer circumference of the exterior member 30, other structures are not particularly limited.

[0085] · The protruding part 45 of the above embodiment may be provided at a position farther from the insertion port 40X than the tip of the first end part 41 in the circumferential direction of the first path restriction member 40. · The protruding part 46 of the above embodiment may be provided at a position farther from the insertion port 40X than the tip of the second end part 42 in the circumferential direction of the first path restriction member 40.

[0086] ·The protruding portions 45 and 46 of the above-described 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-described embodiment may be omitted.

That is, the first path restricting member 40 and the second path restricting member 50 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 50 are not attached.
