[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 includes [1] a wire harness body having a wire member, an exterior member covering the outer periphery of the wire member, and a first path regulating member attached to the outer periphery of the exterior member for regulating the path of the exterior member; and an attachment member attached to the outer periphery of a part of the length direction of the first path regulating member, wherein the first path regulating member has an insertion opening that opens in a direction orthogonal to the length direction of the first path regulating member and extends over the entire length direction of the first path regulating member, the attachment member has a covering portion covering the outer periphery of the first path regulating member and a pressing member attached to the covering portion, the covering portion has a fixing hole penetrating from the outer peripheral side to the inner peripheral side of the covering portion, the pressing member has a fixing portion fixed to the fixing hole and a protruding portion protruding from the fixing portion to the inner peripheral side of the covering portion, and the protruding portion is in contact with the wire harness body and presses the wire harness body against the inner peripheral surface of the covering portion.

[0010] According to this configuration, the wire harness body passing through the inside of the covering portion is pressed against the inner peripheral surface of the covering portion by the pressing member fixed to the fixing hole of the covering portion. Thereby, it is possible to suppress rattling between the covering portion and the wire harness body.

[0011] [2] The protruding portion enters the insertion opening, and the protruding portion is in contact with the outer peripheral surface of the exterior member and presses the exterior member. According to this configuration, the protruding portion that contacts the exterior member can press the exterior member and the first path restricting member against the inner peripheral surface of the covering portion. Further, since the protruding portion enters the insertion opening of the first path restricting member, both circumferential ends of the first path restricting member that forms the insertion opening can be circumferentially engaged with the protruding portion of the pressing member. Therefore, it is possible to suppress the first path restricting member from rotating in the circumferential direction by the protruding portion.

[0012] [3] The protruding portion contacts the outer peripheral surface of the first path restricting member and presses the first path restricting member. According to this configuration, the protruding portion that contacts the first path restricting member can press the first path restricting member against the inner peripheral surface of the covering portion.

[0013] [4] The pressing member is a screw having a male screw portion that is screwed into the fixing hole, and a part of the male screw portion constitutes the protruding portion. According to this configuration, it is possible to configure a pressing member that presses the wire harness main body by a simple operation of screwing the screw into the fixing hole until the tip of the male screw portion abuts against the wire harness main body.

[0014] [5] The fixing portion is press-fitted and fixed into the fixing hole. According to this configuration, it is possible to configure a pressing member that presses the wire harness main body by a simple operation of press-fitting the fixing portion of the pressing member into the fixing hole.

[0015] [6] A plurality of fixing holes are provided. The pressing member is attached to some of the plurality of fixing holes, and some of the plurality of fixing holes are open fixing holes that are not attached with the pressing member and are in an open state.

[0016] According to this configuration, it is possible to select a fixing hole for attaching the pressing member from a plurality of fixing holes. As a result, the degree of freedom in attaching the pressing member is improved. Further, it is possible to discharge water that has entered between the covering portion and the wire harness main body to the outside of the covering portion through the open fixing hole.

[0017] [7] The attachment member includes a main body portion that regulates 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 regulating member together with the receiving portion. The receiving portion and the lid portion constitute the covering portion. According to this configuration, it is possible to form a covering portion that covers the outer circumference of the first path regulating member by the receiving portion and the lid portion.

[0018] [8] The fixing hole is provided in the lid portion. According to this configuration, it is possible to attach a pressing member to the fixing hole provided in the lid portion.

[0019] [9] The attachment member is a second path regulating member that is attached to the outer circumference of the exterior member and regulates the path of the exterior member. The covering portion is provided at an end in the length direction of the second path regulating member and covers the outer circumference of the end in the length direction of the first path regulating member.

[0020] According to this configuration, the covering portion is provided at an end in the length direction of the second path regulating member and covers the outer circumference of the end in the length direction of the first path regulating member. Therefore, the first path regulating member and the second path regulating member are connected in the length direction. Thus, the path of the exterior member is continuously regulated by the first path regulating member and the second path regulating member.

[0021]

[10] The first path regulating member regulates the path of a straight portion that is a straight portion in the path of the wire harness main body, and the second path regulating member regulates the path of a bent portion that is a bent portion in the path of the wire harness main body.

[0022] 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 respectively.

[0023] [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, the term "orthogonal" in this specification includes not only the case of strict orthogonality but also the case of approximate orthogonality within the range where the actions and effects in the present embodiment are achieved.

[0024] In addition, the term "opposite" 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, the term "opposite" 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.

[0025] 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.

[0026] (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 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 body such as under the floor of the vehicle V.

[0027] 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.

[0028] 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. Further, the wire harness body 11 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 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.

[0029] 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 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.

[0030] (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.

[0031] 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.

[0032] 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.

[0033] The insulating coating 23 covers, for example, the outer peripheral surface of the core wire 22 over the entire circumference in the circumferential direction. The insulating coating 23 is composed of, for example, a resin material having insulating properties. The cross-sectional shape of the wire 21 cut by a plane orthogonal to the longitudinal 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 into, for example, a circular shape, a semi-circular shape, a polygonal shape, a square shape, a flat shape, or the like. The cross-sectional shape of each wire 21 in this embodiment is formed into a circular shape.

[0034] 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 not shown, both ends in the length direction of the braided member 25 are grounded, for example, at connectors C1, C2 (see FIG. 1).

[0035] (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.

[0036] The exterior member 30 has, for example, flexibility and can be easily bent. Examples of the flexible exterior member 30 include, for example, a resin corrugated tube and a rubber waterproof cover. The exterior member 30 of the present embodiment is a resin corrugated tube having a bellows shape in which the diameter repeats in a large and small 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 diameter smaller than that of 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.

[0037] (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 makes it 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.

[0038] 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 to the outer periphery of the exterior member 30, for example, at a straight portion 11A which 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 the first path restricting member 40 may be provided singly or in plural according to the path of the wire harness main body 11.

[0039] 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 which 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 the second path restricting member 50 may be provided singly or in plural according to the path of the wire harness main body 11.

[0040] (Configuration of the first path restricting member 40) As shown in FIGS. 2 and 4, the first path regulating member 40 covers a part in the circumferential direction of the outer periphery of the exterior member 30. The first path regulating member 40 has a shape that covers the outer periphery of the exterior member 30 in a part in the circumferential direction of the exterior member 30. The cross-sectional shape of the first path regulating member 40 is generally C-shaped as a whole. The first path regulating member 40 covers, for example, a range larger than half of the outer periphery of the exterior member 30. That is, the first path regulating member 40 covers a range larger than half of the entire circumference in the circumferential direction of the outer periphery of the exterior member 30.

[0041] 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 linearly extends 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.

[0042] 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.

[0043] 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.

[0044] The connecting portion 43 constitutes the main part of the first path regulating member 40. The radial thickness of the connecting portion 43 is, for example, uniform in the circumferential direction of the first path regulating member 40. The cross-sectional shape of the connecting portion 43 is formed, for example, in a shape along the outer surface of the exterior member 30. The cross-sectional shapes of the first end portion 41, the second end portion 42, and the connecting portion 43 are formed, for example, in an arc shape.

[0045] 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, the 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.

[0046] 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.

[0047] The first path restricting member 40 has a convex portion 45 protruding from the inner surface of the first end portion 41 and a convex portion 46 protruding from the inner surface of the second end portion 42. Each of the convex portions 45, 46 protrudes toward the exterior member 30 inserted inside the first path restricting member 40 and contacts the outer surface of the exterior member 30. Each of the convex portions 45, 46 contacts the outer surface of the large-diameter portion 31 of the exterior member 30. The convex portion 45 protrudes, for example, from the inner surface at the tip of the first end portion 41. The convex portion 46 protrudes, for example, from the inner surface at the tip of the second end portion 42. The cross-sectional shape of each of the convex portions 45, 46 is formed, for example, in a curved shape. The cross-sectional shape of each of the convex portions 45, 46 in the present embodiment is formed in an arc shape. Each of the convex portions 45, 46 extends in the length direction of the first path restricting member 40. Each of the convex portions 45, 46 extends, for example, over the entire length in the length direction of the first path restricting member 40.

[0048] Each of the convex 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 convex portion 45, the convex portion 46, and the connecting portion 43. Thereby, the connection of the first path restricting member 40 to the exterior member 30 becomes strong.

[0049] 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 restricting member 40 elastically deforms. For example, the opening width of the insertion port 40X becomes larger when the exterior member 30 is inserted into the insertion port 40X from a direction orthogonal to the length direction of the first path restricting member 40. When the exterior member 30 is inserted inside the first path restricting member 40, the first path restricting member 40 elastically returns to 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 restricting member 40 is attached to the outer periphery of the exterior member 30.

[0050] (Configuration of the second path restricting 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.

[0051] 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.

[0052] 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 that extends 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 that is 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.

[0053] 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 formed integrally with one end portion in the length direction of the main body portion 51 and a lid portion 54 that covers the receiving portion 53.

[0054] The receiving part 53 covers a part in the circumferential direction of the outer periphery of the first path restricting member 40. The receiving part 53 covers a part in the circumferential direction at the end in the longitudinal direction of the first path restricting member 40. The receiving part 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 part 53 is generally a semi-cylindrical shape. The receiving part 53 has, for example, a semi-cylindrical shape with a larger diameter than the main body part 51. The receiving part 53 covers, for example, half of the outer periphery of the first path restricting member 40.

[0055] The lid part 54, together with the receiving part 53, covers the entire circumference of the end of the first path restricting member 40. Specifically, the lid part 54, together with the receiving part 53, covers the entire circumferential direction along the outer periphery of the end of the first path restricting member 40. The lid part 54 in the present embodiment covers a part of the outer periphery of the first path restricting member 40 and a part exposed from the insertion port 40X on the outer periphery of the exterior member 30.

[0056] The cross-sectional shape of the lid part 54 is generally a semi-cylindrical shape. The lid part 54 has a semi-cylindrical shape with the same diameter as that of the receiving part 53. The lid part 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 part 53 and covers half of the circumferential direction along the outer periphery of the first path restricting member 40.

[0057] The lid part 54 is, for example, separate from the receiving part 53. The receiving part 53 has a first connecting part 55. The first connecting part 55 is provided at both ends in the circumferential direction of the receiving part 53. The first connecting part 55 protrudes radially outward from both ends in the circumferential direction of the receiving part 53.

[0058] The cover portion 54 has a second connecting portion 56. The second connecting portions 56 are provided at both circumferential ends of the cover 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 cover portion 54 are held so as not to separate from each other.

[0059] (Configuration of the screw 60) As shown in FIG. 4, the second path restricting member 50 has a screw 60 as a pressing member attached to the covering portion 52. The cover portion 54 of the present embodiment has a fixing hole 58 to which the screw 60 is attached from the outer peripheral side of the covering portion 52. The fixing hole 58 penetrates from the outer peripheral side to the inner peripheral side of the covering portion 52. The fixing hole 58 penetrates the cover portion 54 along, for example, the radial direction of the covering portion 52. The fixing hole 58 is provided at a position corresponding to the insertion port 40X of the first path restricting member 40. That is, the fixing hole 58 faces the insertion port 40X in the radial direction of the covering portion 52. An internal thread (not shown) is formed on the inner peripheral surface of the fixing hole 58. The fixing hole 58 penetrates from the outer peripheral side to the inner peripheral side of the covering portion 52. Therefore, it is possible to attach the screw 60 from the outer peripheral side of the covering portion 52 to the fixing hole 58 in a state where the receiving portion 53 and the cover portion 54 are assembled annularly to cover the entire circumference of the wire harness body 11.

[0060] The screw 60 has a male screw portion 61. The male screw portion 61 has a spiral thread on the outer peripheral surface of a cylinder or a cone. The male screw portion 61 is screwed and fixed to the fixing hole 58. The male screw portion 61 has a fixing portion 62 fixed to the fixing hole 58 and a protruding portion 63 protruding from the fixing portion 62 to the inner peripheral side of the covering portion 52. The fixing portion 62 is a portion of the male screw portion 61 located inside the fixing hole 58.

[0061] The protruding portion 63 is a portion that protrudes from the fixing hole 58 to the inner peripheral side of the covering portion 52 in the male screw portion 61. The protruding portion 63 has entered the insertion port 40X of the first path regulating member 40. That is, the protruding portion 63 is located between the first end portion 41 and the second end portion 42 of the first path regulating member 40. Thereby, the first end portion 41 and the second end portion 42 can be engaged with the protruding portion 63 in the circumferential direction. And the tip of the protruding portion 63 is in contact with the outer peripheral surface of the exterior member 30 exposed from the insertion port 40X and presses the exterior member 30. By the pressing of this screw 60, the connecting portion 43 of the first path regulating member 40 is pressed against the inner peripheral surface of the receiving portion 53.

[0062] As shown in FIG. 2, the wire harness 10 has, for example, a first slide regulating member 71 that regulates the slide movement of the first path regulating member 40 with respect to the length direction of the exterior member 30. Further, the wire harness 10 has, for example, a second slide regulating member 72 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 first slide regulating member 71 and the second slide regulating 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 regulating member 71 and the second slide regulating member 72 of the present embodiment are adhesive tapes. The first slide regulating member 71 is wound around the end of the first path regulating member 40 on the side not connected to the second path regulating member 50 and the exterior member 30. The second slide regulating member 72 is wound around the end of the second path regulating member 50 on the side not connected to the first path regulating member 40 and the exterior member 30.

[0063] The effects of this embodiment will be described. (1) The second path restricting member 50 as a mounting member has a covering portion 52 that covers the outer periphery of the first path restricting member 40, and a screw 60 as a pressing member attached to the covering portion 52. The covering portion 52 has a fixing hole 58 that penetrates from the outer peripheral side to the inner peripheral side of the covering portion 52. The screw 60 has a fixing portion 62 fixed to the fixing hole 58 and a protruding portion 63 that protrudes from the fixing portion 62 to the inner peripheral side of the covering portion 52. And the protruding portion 63 is in contact with the wire harness body 11 and presses the wire harness body 11 against the inner peripheral surface of the covering portion 52.

[0064] According to this configuration, the wire harness body 11 passing through the inside of the covering portion 52 is pressed against the inner peripheral surface of the covering portion 52 by the screw 60 fixed to the fixing hole 58 of the covering portion 52. Thereby, it becomes possible to suppress the rattling between the covering portion 52 and the wire harness body 11. In the above embodiment, when the screw 60 presses the wire harness body 11 against the inner peripheral surface of the covering portion 52, the receiving portion 53 and the lid portion 54 are pushed and expanded in the direction in which they separate. 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. As a result, for example, damage to the attachment site between the first path restricting member 40 and the second path restricting member 50 can be suppressed, and thus the path of the wire harness body 11 can be stably restricted.

[0065] (2) The protruding portion 63 has entered the insertion port 40X. And the protruding portion 63 is in contact with the outer peripheral surface of the exterior member 30 and presses the exterior member 30. According to this configuration, it becomes possible to press the exterior member 30 and the first path restricting member 40 against the inner peripheral surface of the covering portion 52 by the protruding portion 63 that contacts the exterior member 30. Further, the protruding portion 63 has entered the insertion port 40X of the first path restricting member 40. For this reason, the first end portion 41 and the second end portion 42 of the first path restricting member 40 that form the insertion port 40X can be engaged with the protruding portion 63 in the circumferential direction. Therefore, it becomes possible to suppress the first path restricting member 40 from rotating in the circumferential direction by the protruding portion 63.

[0066] (3) The pressing member that presses the wire harness body 11 is a screw 60 having a male screw portion 61 that screws into the fixing hole 58. And a part of the male screw portion 61 constitutes a protruding portion 63.

[0067] According to this configuration, until the tip of the male screw portion 61 abuts against the wire harness body 11, by a simple operation of screwing the screw 60 into the fixing hole 58, it becomes possible to configure a pressing member that presses the wire harness body 11.

[0068] (4) The second path restricting member 50 includes a main body portion 51 that restricts the path of the exterior member 30, and a receiving portion 53 provided at an end of the main body portion 51 in the length direction of the wire harness body 11. Further, the second path restricting member 50 includes a lid portion 54 that covers the entire circumference of the first path restricting member 40 together with the receiving portion 53. The receiving portion 53 and the lid portion 54 constitute a covering portion 52. According to this configuration, it becomes possible to configure a covering portion 52 that covers the outer circumference of the first path restricting member 40 by the receiving portion 53 and the lid portion 54.

[0069] (5) The fixing hole 58 is provided in the lid portion 54. According to this configuration, it becomes possible to attach the screw 60 to the fixing hole 58 provided in the lid portion 54. (6) The attachment member attached to the first path restricting member 40 is the second path restricting member 50 that is attached to the outer circumference of the exterior member 30 and restricts the path of the exterior member 30. And the covering portion 52 is provided at an end in the length direction of the second path restricting member 50 and covers the outer circumference 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.

[0070] (7) 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 respectively.

[0071] 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 above embodiment, the fixing hole 58 is configured to face the insertion port 40X of the first path restricting member 40 in the radial direction. However, the present invention is not limited to this, and the fixing hole 58 may be provided so as to face the outer peripheral surface of the connecting portion 43 in the first path restricting member 40 in the radial direction.

[0072] · In the covering portion 52 of the above embodiment, the fixing hole 58 is provided in the lid portion 54. However, the present invention is not limited to this, and the fixing hole 58 may be provided in the receiving portion 53. · In the above embodiment, the pressing member for pressing the wire harness main body 11 and the screw 60 are used. However, the present invention is not particularly limited thereto, and the configuration of the pressing member can be appropriately changed.

[0073] For example, in the configuration shown in FIG. 5, as the pressing member 80 for pressing the wire harness main body 11, a pin - shaped member instead of a screw is used. The pressing member 80 has a fixing portion 81 fixed to the fixing hole 58x formed in the covering portion 52, and a protruding portion 82 protruding from the fixing portion 81 to the inner peripheral side of the covering portion 52. The fixing portion 81 has the same shape as the fixing hole 58x when viewed from the penetrating direction of the fixing hole 58x. The fixing portion 81 is press - fitted and fixed in the fixing hole 58x. The shapes of the fixing hole 58x and the fixing portion 81 when viewed from the penetrating direction are, for example, circular, elliptical, polygonal, etc.

[0074] The protruding portion 82 contacts the wire harness main body 11 and presses the wire harness main body 11 against the inner peripheral surface of the covering portion 52. Specifically, the protruding portion 82 enters the insertion port 40X. And the protruding portion 82 contacts the outer peripheral surface of the exterior member 30 and presses the exterior member 30. Due to the pressing of this screw 60, the connecting portion 43 of the first path restricting member 40 is pressed against the inner peripheral surface of the receiving portion 53.

[0075] Even with such a configuration, effects substantially the same as those of the above-described embodiment can be obtained. Also, according to the configuration shown in FIG. 5, the pressing member 80 has a fixing portion 81 that is press-fitted and fixed into the fixing hole 58x. Therefore, by a simple operation of press-fitting the fixing portion 81 into the fixing hole 58x, it becomes possible to press the wire harness main body 11 against the covering portion 52 by the pressing member 80.

[0076] · The protruding portion 63 of the screw 60 in the above-described embodiment enters the insertion port 40X of the first path restricting member 40 and contacts the outer peripheral surface of the exterior member 30, but it is not particularly limited to this, and the protruding portion 63 may be configured to contact the outer peripheral surface of the first path restricting member 40.

[0077] For example, in the configuration shown in FIG. 6, the fixing hole 58 is provided in the receiving portion 53 of the covering portion 52. The fixing hole 58 is located radially outside the connecting portion 43 of the first path restricting member 40. That is, the fixing hole 58 is radially opposed to the connecting portion 43. And in the screw 60 screwed into the fixing hole 58, the protruding portion 63, which is a part including the tip of the male screw portion 61, contacts the outer peripheral surface of the connecting portion 43 of the first path restricting member 40 and presses the connecting portion 43.

[0078] According to this configuration, the protruding portion 63 that contacts the first path restricting member 40 can press the first path restricting member 40 against the inner peripheral surface of the covering portion 52. That is, even with such a configuration, the wire harness main body 11 is pressed against the inner peripheral surface of the covering portion 52 by the screw 60, and as a result, it is possible to suppress the rattling between the covering portion 52 and the wire harness main body 11. In the configuration shown in FIG. 6, it is possible to replace the screw 60 and the fixing hole 58 with the pressing member 80 and the fixing hole 58x in the configuration shown in FIG. 5.

[0079] · In the covering portion 52 of the above embodiment, the number of the fixing holes 58 is one, but it is not particularly limited thereto, and a plurality of fixing holes 58 may be provided in the covering portion 52. For example, in the configuration shown in FIG. 7, a plurality of fixing holes 58 are provided in the receiving portion 53. The plurality of fixing holes 58 are arranged, for example, along the length direction of the wire harness main body 11. In FIG. 7, for the sake of simplifying the drawing, the surface shape of the exterior member 30 is simplified and illustrated.

[0080] Screws 60 are attached to some of the plurality of fixing holes 58, which are fixing holes 58y. And among the plurality of fixing holes 58, the fixing holes 58 to which the screws 60 are not attached are open fixing holes 58z in an open state. In the example of FIG. 7, the number of the fixing holes 58 is two, one of which is the fixing hole 58y and the other is the open fixing hole 58z, but the numbers of the fixing hole 58y and the open fixing hole 58z can be changed as appropriate. The open fixing hole 58z is a hole similar to the fixing hole 58y although the screw 60 is not attached thereto, and a screw 60 can be screwed into the hole.

[0081] In the screw 60 screwed into the fixing hole 58y, the protruding portion 63, which is a part including the tip of the male screw portion 61, contacts the outer peripheral surface of the connecting portion 43 in the first path restricting member 40 and presses the connecting portion 43 in the same manner as the configuration shown in FIG. 6. Thereby, the first path restricting member 40 is pressed against the inner peripheral surface of the covering portion 52.

[0082] According to this configuration, it becomes possible to select the fixing hole 58 for attaching the screw 60 from among a plurality of fixing holes 58. As a result, the degree of freedom in attaching the screw 60 is improved. Also, it becomes possible to discharge the water that has entered between the covering portion 52 and the wire harness main body 11 to the outside of the covering portion 52 through the open fixing hole 58z. In the configuration shown in FIG. 7, when the screw 60 presses the outer peripheral surface of the connecting portion 43, a clearance S is created between the outer peripheral surface of the connecting portion 43 and the inner peripheral surface of the covering portion 52. Then, it becomes possible to discharge the water that has entered the clearance S to the outside of the covering portion 52 through the open fixing hole 58z.

[0083] In addition, in the configuration shown in FIG. 7, the screw 60 and the fixing hole 58 can be replaced with the pressing member 80 and the fixing hole 58x in the configuration shown in FIG. 5. Also, the arrangement of the plurality of fixing holes 58 is not limited to the above configuration, and the plurality of fixing holes 58 may be arranged side by side, for example, along the circumferential direction of the wire harness main body 11. Further, in the example shown in FIG. 7, the plurality of fixing holes 58 are provided in the receiving portion 53, but not limited thereto, the plurality of fixing holes 58 may be provided in the lid portion 54. Or, the fixing holes 58 may be provided in each of the receiving portion 53 and the lid portion 54.

[0084] ·In the above embodiment, the covering portion 52 is configured to have the receiving portion 53 and the lid portion 54, but is not limited thereto. For example, the covering portion 52 may be changed to a configuration that is a non-detachable and non-deformable cylindrical shape.

[0085] Also, the lid portion 54 in 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. 8, 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 circumferential end of the receiving portion 53 and one circumferential end of the lid portion 54. A lock portion 92 is provided at the other circumferential end of the receiving portion 53. A claw portion 93 is provided at the other circumferential end of the lid portion 54.

[0086] The lid portion 54 is rotatable about the hinge portion 91 as an axis between an open position and a closed position shown in FIG. 8. 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. 8, it is possible to suppress rattling between the covering portion 52 and the wire harness body 11 by the pressing of the screw 60.

[0087] Also, in the above-described configuration, rattling occurs between the receiving portion 53 and the lid portion 54 due to the clearance between the thin hinge portion 91 and the claw portion 93. As a result, rattling between the covering portion 52 and the first path restricting member 40 is more likely to occur. For this reason, by providing the screw 60 in the above-described configuration, the rattling suppression effect by the screw 60 can be obtained more remarkably. In the configuration shown in FIG. 8, the screw 60 and the fixing hole 58 can be replaced with the pressing member 80 and the fixing hole 58x in the configuration shown in FIG. 5.

[0088] · The penetrating direction of the fixing hole 58 is not limited to the direction along the radial direction of the covering portion 52. As long as the fixing hole 58 penetrates from the outer peripheral side to the inner peripheral side of the covering portion 52, the penetrating direction of the fixing hole 58 does not have to be the direction along the radial direction.

[0089] · 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.

[0090] · 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 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 body 11. In this case, the second path restricting member 50 is changed to a shape in which the bent shape in the main body portion 51 extends linearly, for example.

[0091] ·In the above-described 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.

[0092] ·The structure of the first path restricting member 40 of the above-described embodiment can be appropriately changed. For example, the first path restricting member 40 has an insertion port 40X and is attachable to the outer periphery of the exterior member 30. Other structures are not particularly limited as long as it has such a structure.

[0093] ·The convex portion 45 of the above-described 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 convex portion 46 of the above-described 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.

[0094] ·The convex portions 45 and 46 of the above-described embodiment may be partially provided in the length direction of the first path restricting member 40. ·At least one of the convex portions 45 and 46 of the above-described embodiment may be omitted.

[0095] ·The shape of the connecting portion 43 in the first path restricting member 40 of the above-described embodiment is not limited to an arc shape, and can be changed to, for example, an elliptical arc shape or a U shape. ·In the above-described embodiment, the first path restricting member 40 and the second path restricting member 50 are assumed to be harder than the exterior member 30, but it is not limited thereto, and they may have the same or lower hardness than the exterior member 30. That is, the first path restricting member 40 and the second path restricting member 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.

[0096] · The exterior member 30 of the above embodiment may be, for example, one in which a metal layer containing a metal material is provided on the outer surface of a corrugated tube made of resin. · The exterior member 30 of the above embodiment is not limited to a corrugated tube, and may be, for example, an exterior member that does not have a large-diameter portion 31 and a small-diameter portion 32.
