Modes 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 is [1] A wire harness body having a wire member, an exterior member covering the outer periphery of the wire member, and a first path restricting member attached to the outer periphery of the exterior member and restricting the path of the exterior member, and an attachment member attached to the outer periphery of a part of the first path restricting member in the longitudinal direction, wherein the first path restricting member has an insertion port that opens in a direction orthogonal to the longitudinal direction of the first path restricting member and extends over the entire longitudinal direction of the first path restricting member, the attachment member has a covering portion covering the outer periphery of the first path restricting member, the covering portion has a through hole penetrating from the outer peripheral side to the inner peripheral side of the covering portion, and the wire harness includes a filling agent filled between the wire harness body and the covering portion through the through hole.
[0010] According to this configuration, the wire harness body passing through the inside of the covering portion is in a state of being pressed against the covering portion by the filling agent filled between the covering portion and the wire harness body. Thereby, it is possible to suppress rattling between the covering portion and the wire harness body.
[0011] [2] The filling agent has entered the insertion port, and the filling agent is interposed between the outer peripheral surface of the exterior member and the inner peripheral surface of the covering portion. According to this configuration, it is possible to press the exterior member and the first path restricting member against the covering portion by the filling agent filled between the exterior member and the covering portion. Further, since the filling agent has entered the insertion port of the first path restricting member, it is possible to suppress the first path restricting member from rotating in the circumferential direction by the filling agent. Further, since the filling agent has entered the insertion port of the first path restricting member, it is possible to make the covering portion smaller in the radial direction compared to a configuration in which the filling agent is provided in contact with the outer peripheral surface of the first path restricting member.
[0012] [3] The through hole faces the insertion port in the radial direction of the covering portion. According to this configuration, it is possible to suitably allow the filling agent to enter the insertion port. [4] The through hole faces the outer peripheral surface of the first path restricting member, and the filler is interposed between the outer peripheral surface of the first path restricting member and the inner peripheral surface of the covering portion. According to this configuration, it becomes possible to press the first path restricting member against the covering portion by the filler filled between the first path restricting member and the covering portion.
[0013] [5] A part of the filler has entered the inside of the through hole. According to this configuration, it becomes possible to block the through hole with the filler. [6] The attachment member includes a main body portion that restricts the path of the exterior member, a receiving portion provided at an end of the main body portion in the length direction of the wire harness main body, and a lid portion that covers the entire circumference of the first path restricting member together with the receiving portion. The receiving portion and the lid portion constitute the covering portion. According to this configuration, it becomes possible to constitute a covering portion that covers the outer periphery of the first path restricting member by the receiving portion and the lid portion.
[0014] [7] The through hole is provided in the lid portion. According to this configuration, it becomes possible to fill the filler from the through hole provided in the lid portion. [8] The filler is made of a resin material. According to this configuration, it becomes possible to suitably press the wire harness main body against the covering portion by the filler made of the resin material.
[0015] [9] The attachment member is a second path restricting member that is attached to the outer periphery of the exterior member and restricts the path of the exterior member. The covering portion is provided at an end in the length direction of the second path restricting member and covers the outer periphery of an end in the length direction of the first path restricting member.
[0016] According to this configuration, the covering portion is provided at an end in the length direction of the second path restricting member and covers the outer periphery of an end in the length direction of the first path restricting member. Therefore, the first path restricting member and the second path restricting member are connected in the length direction. Thus, the path of the exterior member is continuously restricted by the first path restricting member and the second path restricting member.
[0017]
[10] 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.
[0018] 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 are continuously suppressed from deviating from the desired paths.
[0019] [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 the respective parts may differ in each drawing. Further, "orthogonal" in this specification includes not only cases of strict orthogonality but also cases of approximate orthogonality within the range in which the operations and effects of the present embodiment are exhibited.
[0020] Also, "opposite" in this specification means that surfaces or members are in a position facing each other, and includes not only cases where they are completely in a facing position but also cases where they are partially in a facing position. Further, "opposite" in this specification includes both cases where a member different from the two parts is interposed between the two parts and cases where nothing is interposed between the two parts.
[0021] Also, 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, circular, elliptical, and polygonal shapes having pointed or rounded corners.
[0022] (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 of the vehicle V and a high-voltage battery M2 installed behind the vehicle V relative to the inverter M1. The wire harness 10 is formed in a long shape so as to extend in the longitudinal direction of the vehicle V. The wire harness 10 is routed on 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.
[0023] 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.
[0024] The wire harness 10 has a wire harness main body 11. The wire harness main 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 main body 11 also has a first path regulating member 40 that is attached to the outer periphery of the outer member 30 and regulates the path of the outer member 30 (see FIG. 2). 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.
[0025] As shown in FIG. 2, the wire harness 10 has a second path regulating member 50 attached to the outer periphery of the outer member 30. The first path regulating member 40 and the second path regulating member 50 regulate the path along which the wire harness main body 11 is routed. In FIG. 1, the illustration of the first path regulating member 40 and the second path regulating member 50 is omitted.
[0026] (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.
[0027] 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.
[0028] 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 composed 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.
[0029] The insulating coating 23 covers, for example, the outer peripheral surface of the core wire 22 over the entire circumferential direction. The insulating coating 23 is composed of, for example, a resin material having insulating properties. The cross-sectional shape of the wire 21 cut 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.
[0030] 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 ends in the length direction of the braided member 25 are grounded, for example, at connectors C1, C2 (see FIG. 1).
[0031] (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.
[0032] 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 pattern 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 connected 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 simplicity of the drawing, the exterior member 30 is shown in a simplified manner.
[0033] (Configuration of the first path restricting member 40 and the second path restricting member 50) As shown in FIGS. 2 and 3, 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 deflect due to its own weight or the like and deviate from the desired path.
[0034] As shown in FIG. 2, 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, for example, to the outer periphery of the exterior member 30 at a straight portion 11A that is a straight 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.
[0035] 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, for example, to the outer periphery of the exterior member 30 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.
[0036] (Configuration of the first path restricting member 40) As shown in FIGS. 2 and 4, the first path restricting member 40 covers a part in the circumferential direction of the outer periphery of the exterior member 30. The first path restricting member 40 has a shape that covers the outer periphery of the exterior member 30 in a part in the circumferential direction of the exterior member 30. The cross-sectional shape of the first path restricting member 40 is generally C-shaped as a whole. The first path restricting member 40 covers, for example, a range larger than half of the outer periphery of the exterior member 30. That is, the first path restricting 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.
[0037] As shown in FIG. 2, the first path restricting member 40 extends along the length direction of the exterior member 30 in the straight portion 11A. The first path restricting member 40 is formed, for example, in a shape that linearly extends in one direction. The cross-sectional shape of the first path restricting member 40 is, for example, uniform over the entire length in the length direction of the first path restricting member 40.
[0038] The first path restricting member 40 is made of, for example, metal or resin. The first path restricting member 40 of the present embodiment is made of resin. As the material of the first path restricting member 40, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used. The first path restricting member 40 can be manufactured by well-known manufacturing methods such as extrusion molding and injection molding. In the present embodiment, the first path restricting member 40 is an extruded product manufactured by extrusion molding. Therefore, the first path restricting member 40 can be easily manufactured by using an extrusion molding machine that extrudes the raw material of the first path restricting member 40 in the length direction. Also, a plurality of types of first path restricting 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 first path restricting members 40 having different dimensions in the length direction can be manufactured by cutting the base material of the first path restricting member 40 formed by a single extrusion molding machine to an arbitrary length using a cutting machine.
[0039] As shown in FIGS. 3 and 4, the first path restricting member 40 has an insertion port 40X that opens in a direction orthogonal to the length direction of the first path restricting member 40. The insertion port 40X extends over the entire length direction of the first path restricting member 40. The first path restricting 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 restricting member 40 and form the insertion port 40X. The first path restricting 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 restricting 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] The connecting portion 43 constitutes the main part of the first path restricting member 40. The radial thickness of the connecting portion 43 is, for example, uniform in the circumferential direction of the first path restricting 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.
[0041] The first end portion 41 and the second end portion 42 are provided on opposite sides in the circumferential direction of the first path restricting 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 restricting 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 restricting member 40 is configured as the insertion port 40X. Thus, the first path restricting member 40 is formed in a C shape having the insertion port 40X in a part of the circumferential direction of the first path restricting 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 regulating member 40 has a protruding portion 45 protruding from the inner surface of the first end portion 41 and a protruding portion 46 protruding from the inner surface of the second end portion 42. Each of the protruding portions 45, 46 protrudes toward the exterior member 30 inserted inside the first path regulating member 40 and contacts the outer surface of the exterior member 30. Each of the protruding portions 45, 46 contacts the outer surface of the large diameter portion 31 of the exterior member 30. The protruding portion 45 protrudes, for example, from the inner surface of the tip of the first end portion 41. The protruding portion 46 protrudes, for example, from the inner surface of the tip of the second end portion 42. The cross-sectional shape of each of the protruding portions 45, 46 is formed, for example, in a curved shape. The cross-sectional shape of each of the protruding portions 45, 46 in the present embodiment is formed in an arc shape. Each of the protruding portions 45, 46 extends in the length direction of the first path regulating member 40. Each of the protruding portions 45, 46 extends, for example, over the entire length in the length direction of the first path regulating member 40.
[0044] 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 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.
[0045] 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 becomes larger when the first path regulating 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 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 try to return 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.
[0046] (Configuration of the second path regulating member 50) As shown in FIG. 2, the second path restricting member 50 is attached to the outer periphery of the exterior member 30 at the bent portion 11B. The second path restricting member 50 extends along the length direction of the exterior member 30 at the bent portion 11B. The second path restricting member 50 is bent, for example, along the shape of the bent portion 11B.
[0047] The second path restricting member 50 is made of, for example, metal or resin. The second path restricting member 50 of the present embodiment is made of resin. As the material of the second path restricting member 50, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used. The second path restricting member 50 can be manufactured by a well-known manufacturing method such as injection molding.
[0048] As shown in FIGS. 2, 3, and 4, the second path restricting member 50 has a main body portion 51 and a covering portion 52 that covers the end portion in the length direction of the first path restricting member 40. The main body portion 51 is formed, for example, in an elongated shape extending along the length direction of the exterior member 30 at the bent portion 11B. The main body portion 51 extends, for example, along the path of the bent portion 11B. That is, the main body portion 51 has a bent shape bent along the shape of the bent portion 11B. 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 covers, for example, about half of the outer periphery of the exterior member 30. For example, the main body portion 51 covers a range of about 180° on the outer periphery of the exterior member 30. The main body portion 51 has, for example, a substantially semi-cylindrical shape.
[0049] The covering portion 52 is provided at one end portion in the length direction of the main body portion 51. The covering portion 52 has a receiving portion 53 integrally formed at one end portion in the length direction of the main body portion 51, and a lid portion 54 that covers the receiving portion 53.
[0050] The receiving portion 53 covers a part in the circumferential direction of the outer periphery of the first path restricting member 40. The receiving portion 53 covers a part in the circumferential direction at the end portion in the longitudinal direction of the first path restricting member 40. The receiving portion 53 has a shape that covers the outer periphery of the first path restricting member 40 in a part in the circumferential direction. The cross-sectional shape of the receiving portion 53 is generally a semi-cylindrical shape as a whole. The receiving portion 53 has, for example, a semi-cylindrical shape with a larger diameter than the main body portion 51. The receiving portion 53 covers, for example, half of the outer periphery of the first path restricting member 40.
[0051] The lid portion 54, together with the receiving portion 53, covers the entire circumference of the end portion of the first path restricting member 40. Specifically, the lid portion 54, together with the receiving portion 53, covers the entire circumferential direction along the outer periphery of the end portion of the first path restricting member 40. The lid portion 54 of the present embodiment covers a part of the outer periphery of the first path restricting member 40 and a portion exposed from the insertion port 40X on the outer periphery of the exterior member 30.
[0052] The cross-sectional shape of the lid portion 54 is generally a semi-cylindrical shape as a whole. The lid portion 54 has a semi-cylindrical shape with the same diameter as that of the receiving portion 53. The lid portion 54 covers a part in the circumferential direction along the outer periphery of the first path restricting member 40 that is not covered by the receiving portion 53 and covers half of the circumferential direction along the outer periphery of the first path restricting member 40.
[0053] The lid portion 54 is, for example, separate from the receiving portion 53. The receiving portion 53 has a first connecting portion 55. The first connecting portion 55 is provided at both end portions in the circumferential direction of the receiving portion 53. The first connecting portion 55 protrudes radially outward from both end portions in the circumferential direction of the receiving portion 53.
[0054] The lid portion 54 has a second connecting portion 56. The second connecting portion 56 is provided at both circumferential ends of the lid portion 54. Each second connecting portion 56 has a groove 57 into which each first connecting portion 55 is inserted. The groove 57 extends along the length direction of the second path restricting member 50. The second connecting portion 56 is attachable to the first connecting portion 55 by a sliding movement along the length direction of the second path restricting member 50. By connecting the first connecting portion 55 and the second connecting portion 56, the receiving portion 53 and the lid portion 54 are held so as not to separate from each other.
[0055] (Configuration of the filler 60) As shown in FIG. 4, the wire harness 10 includes a filler 60 filled between the covering portion 52 and the wire harness main body 11. The filler 60 is injected from a through hole 58 provided in the lid portion 54 to the inner circumferential side of the covering portion 52. The through hole 58 is a hole that penetrates from the outer circumferential side to the inner circumferential side of the covering portion 52. The through hole 58, for example, penetrates the lid portion 54 along the radial direction of the covering portion 52. The through hole 58 is, for example, a long hole that is long in the length direction of the wire harness main body 11. The through hole 58 is provided at a position corresponding to the insertion port 40X of the first path restricting member 40. That is, the through hole 58 faces the insertion port 40X in the radial direction of the covering portion 52.
[0056] The filler 60 is made of a resin material. Examples of the resin material used for the filler 60 include ethylene copolymers such as EEA (ethylene ethyl acrylate copolymer) and EVA (ethylene vinyl acetate copolymer), and silicone materials such as one-component liquid silicone rubber. When an ethylene copolymer is used for the filler 60, for example, it is possible to inject the filler 60 from the through-hole 58 using a glue gun. When filling the filler 60, first, the molten filler 60 is injected from the through-hole 58 into the inner peripheral side of the covering portion 52. The filler 60 flows into the space between the exterior member 30 and the covering portion 52 inside the insertion port 40X of the first path restricting member 40. Note that the viscosity and injection pressure of the filler 60 are set so that the filler 60 does not cover the entire circumference inside the small-diameter portion 32 of the exterior member 30. Thereby, the space between the exterior member 30 and the covering portion 52 inside the insertion port 40X is appropriately filled with the filler 60.
[0057] After the filler 60 is filled between the exterior member 30 and the covering portion 52, it is solidified. In the solidified state, the filler 60 has a first portion 61 located in the space between the exterior member 30 and the covering portion 52 inside the insertion port 40X. The first portion 61 adheres to the inner peripheral surface of the covering portion 52, the outer peripheral surface of the exterior member 30, and the first end portion 41 and the second end portion 42 of the first path restricting member 40, respectively. The wire harness main body 11 including the exterior member 30 and the first path restricting member 40 is pressed against the inner peripheral surface of the covering portion 52 by the pressure of the first portion 61 of the filler 60. Note that the filler 60 preferably has appropriate elasticity in the solidified state.
[0058] Also, in the solidified state, the filler 60 has a second portion 62 that enters the inside of the through-hole 58. The second portion 62 adheres to the inner peripheral surface of the through-hole 58. The second portion 62 closes the through-hole 58, for example.
[0059] As shown in FIG. 2, the wire harness 10 has, for example, a first slide restricting member 71 that restricts the sliding movement of the first path restricting member 40 with respect to the longitudinal direction of the exterior member 30. Further, the wire harness 10 has, for example, a second slide restricting member 72 that restricts the sliding movement of the second path restricting member 50 with respect to the longitudinal direction of the exterior member 30. As the first slide restricting member 71 and the second slide restricting member 72, for example, a resin or metal binding band, a caulking ring, an adhesive tape, or the like can be used. The first slide restricting member 71 and the second slide restricting member 72 of the present embodiment are adhesive tapes. The first slide restricting member 71 is wound around the end portion of the first path restricting member 40 on the side not connected to the second path restricting member 50 and the exterior member 30. The second slide restricting member 72 is wound around the end portion of the second path restricting member 50 on the side not connected to the first path restricting member 40 and the exterior member 30.
[0060] The effects of the present embodiment will be described. (1) The wire harness 10 includes a filler 60 filled between the wire harness main body 11 and the covering portion 52 through the through hole 58. According to this configuration, the wire harness main body 11 passing through the inside of the covering portion 52 is pressed against the covering portion 52 by the filler 60. Thereby, it becomes possible to suppress the rattling between the covering portion 52 and the wire harness main body 11. In the above embodiment, due to the pressure of the filler 60, the receiving portion 53 and the lid portion 54 are pushed and expanded in a direction away from each other. Thereby, the rattling between the first connecting portion 55 of the receiving portion 53 and the groove 57 of the lid portion 54 is suppressed.
[0061] (2) The first part 61 of the filler 60 has entered the insertion port 40X. And the first part 61 is interposed between the outer peripheral surface of the outer member 30 and the inner peripheral surface of the covering part 52. According to this configuration, the filler 60 filled between the outer member 30 and the covering part 52 can press the outer member 30 and the first path restricting member 40 against the covering part 52. Also, since the filler 60 has entered the insertion port 40X of the first path restricting member 40, it is possible to suppress the first path restricting member 40 from rotating in the circumferential direction by the filler 60. Further, since the filler 60 has entered the insertion port 40X of the first path restricting member 40, it is possible to make the covering part 52 smaller in the radial direction compared to a configuration in which the filler 60 is provided so as to contact the outer peripheral surface of the first path restricting member 40.
[0062] (3) The through hole 58 faces the insertion port 40X in the radial direction of the covering part 52. According to this configuration, it is possible to suitably allow the filler 60 to enter the insertion port 40X. (4) A second part 62 which is a part of the filler 60 has entered the inside of the through hole 58. According to this configuration, it is possible to block the through hole 58 with the filler 60.
[0063] (5) The second path restricting member 50 includes a main body part 51 that restricts the path of the outer member 30, and a receiving part 53 provided at an end of the main body part 51 in the length direction of the wire harness main body 11. Also, the second path restricting member 50 includes a lid part 54 that covers the entire circumference of the first path restricting member 40 together with the receiving part 53. The receiving part 53 and the lid part 54 constitute the covering part 52. According to this configuration, it is possible to constitute the covering part 52 that covers the outer periphery of the first path restricting member 40 by the receiving part 53 and the lid part 54.
[0064] (6) The through hole 58 is provided in the lid part 54. According to this configuration, it is possible to fill the filler 60 from the through hole 58 provided in the lid part 54. (7) The filler 60 is made of a resin material. According to this configuration, it is possible to suitably press the wire harness main body 11 against the covering part 52 by the filler 60 made of the resin material.
[0065] (8) The mounting member attached to the first path restricting member 40 is a second path restricting member 50 that is attached to the outer periphery of the exterior member 30 and restricts the path of the exterior member 30. And the covering portion 52 is provided at the end in the length direction of the second path restricting member 50 and covers the outer periphery of the end in the length direction of the first path restricting member 40. For this reason, the first path restricting member 40 and the second path restricting member 50 are connected in the length direction. Therefore, the path of the exterior member 30 is continuously restricted by the first path restricting member 40 and the second path restricting member 50.
[0066] (9) The first path restricting member 40 restricts the path of the straight portion 11A which is a straight portion in the path of the wire harness main body 11. The second path restricting member 50 restricts the path of the bent portion 11B which is a bent portion in the path of the wire harness main body 11. According to this configuration, 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.
[0067] 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 technically non - conflicting range. · In the covering portion 52 of the above - described embodiment, the through - hole 58 for filling the filler 60 is provided in the lid portion 54, but it is not particularly limited thereto.
[0068] For example, as shown in FIG. 5, a through hole 81 for filling the filler 60 may be provided in the receiving portion 53 of the covering portion 52. As shown in the figure, the through hole 81 is a hole that penetrates from the outer peripheral side to the inner peripheral side of the covering portion 52. The through hole 81 penetrates the receiving portion 53, for example, along the radial direction of the covering portion 52. The through hole 81 is provided at a position corresponding to the outer peripheral surface of the connecting portion 43 in the first path restricting member 40. That is, the through hole 81 faces the outer peripheral surface of the connecting portion 43 in the radial direction of the covering portion 52. The filler 60 filled from the through hole 81 is interposed between the outer peripheral surface of the connecting portion 43 and the inner peripheral surface of the receiving portion 53. Even with such a configuration, the filler 60 filled between the connecting portion 43 of the first path restricting member 40 and the covering portion 52 can press the first path restricting member 40 against the covering portion 52.
[0069] ·In the above embodiment, the covering portion 52 is configured to have the receiving portion 53 and the lid portion 54, but the present invention is not limited to this. For example, the covering portion 52 may be changed to a configuration in which it is a cylindrical shape that cannot be disassembled or deformed.
[0070] Further, the lid portion 54 of the above embodiment is separate from the receiving portion 53, but is not particularly limited thereto, and the lid portion 54 may be integrally formed with the receiving portion 53. For example, in the configuration shown in FIG. 6, the lid portion 54 is integrally formed with the receiving portion 53 via a thin hinge portion 91. That is, the receiving portion 53 and the lid portion 54 are connected by the hinge portion 91. The hinge portion 91 connects one end in the circumferential direction of the receiving portion 53 and one end in the circumferential direction of the lid portion 54. A locking portion 92 is provided at the other end in the circumferential direction of the receiving portion 53. A claw portion 93 is provided at the other end in the circumferential direction of the lid portion 54.
[0071] The lid portion 54 is rotatable about the hinge portion 91 between an open position and a closed position shown in FIG. 6. When the lid portion 54 is in the closed position, the claw portion 93 is caught by the locking portion 92. Thereby, the lid portion 54 is held in the closed position. In this way, the receiving portion 53 and the lid portion 54 are connected to each other. In a state where the receiving portion 53 and the lid portion 54 are connected, the covering portion 52 forms an annular shape that collectively surrounds the outer peripheries of the end portions of the exterior member 30 and the first path restricting member 40. Even if the covering portion 52 has the configuration shown in FIG. 6, it is possible to suppress rattling between the covering portion 52 and the wire harness main body 11 due to the pressure of the filler 60.
[0072] ·In the covering portion 52 of the above-described embodiment, the concavo-convex relationship between the first connecting portion 55 and the second connecting portion 56 may be reversed. That is, the second connecting portion 56 may be inserted into the groove provided in the first connecting portion 55.
[0073] ·The shape of the through hole 58 as viewed in the penetrating direction is not limited to the above-described embodiment, and may be changed to, for example, a circular shape or a polygonal shape. ·The constituent material of the filler 60 is not limited to the above-described embodiment, and can be appropriately changed as long as it is a material having appropriate elasticity and interposed between the wire harness main body 11 and the covering portion 52.
[0074] ·In the covering portion 52 of the above-described embodiment, a plurality of through holes 58 and fillers 60 may be provided in the circumferential direction. For example, a through hole 58 may be additionally provided in the receiving portion 53, and the filler 60 may be filled from the through holes 58 of each of the lid portion 54 and the receiving portion 53.
[0075] ·The second path restricting member 50 of the above-described embodiment is formed to restrict the path of the bent portion 11B of the wire harness main body 11, but is not limited thereto. For example, the second path restricting member 50 may be changed to a shape that restricts the path of the straight portion 11A of the wire harness main body 11. In this case, the second path restricting member 50 is changed to, for example, a shape in which the bent shape in the main body portion 51 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 50, but it 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 in the above embodiment can be appropriately changed. For example, as long as the first path restricting member 40 has an insertion port 40X and a structure that can be attached to the outer periphery of the exterior member 30, other structures are not particularly limited.
[0078] · The protruding portion 45 in 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 in 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 in the above embodiment may be partially provided in the length direction of the first path restricting member 40. · At least one of the protruding portions 45 and 46 in the above embodiment may be omitted.
