[0008] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. [1] A wire harness disclosed herein includes a wire harness main body having electric wire members and an exterior member surrounding an outer periphery of the electric wire members, a path regulating member attached to the outer periphery of the exterior member and regulating a path of the wire harness main body, and a movement regulating member attached to the outer periphery of the exterior member and regulating relative movement of the path regulating member with respect to the exterior member in a longitudinal direction of the exterior member, the exterior member having a bellows shape in which annular convex portions and annular concave portions are alternately connected in the longitudinal direction of the exterior member, the path regulating member has an insertion port that opens in a direction perpendicular to the longitudinal direction of the path regulating member and extends over the entire longitudinal length of the path regulating member, and the movement regulating member has a first engagement portion that fits into the annular concave portion and a second engagement portion that is engageable with an end face of the path regulating member in the longitudinal direction.

[0009] According to this configuration, a movement restricting member is provided that restricts the relative movement of the path restricting member with respect to the exterior member in the length direction of the exterior member. The movement restricting member is provided with a first engagement portion that fits into the annular recess and a second engagement portion that can engage with an end face in the length direction of the path restricting member. According to this, the first engagement portion fits into the annular recess, so that the first engagement portion can be engaged with an inner side surface of the annular recess or a side surface of the annular protrusion in the length direction of the exterior member. This restricts the relative movement of the movement restricting member with respect to the exterior member in the length direction of the exterior member. Therefore, it is possible to restrict the positional deviation of the movement restricting member with respect to the exterior member in the length direction of the exterior member. Furthermore, in the length direction of the exterior member, the end face in the length direction of the path restricting member is engaged with the second engagement portion. This restricts the relative movement of the path restricting member with respect to the exterior member and the movement restricting member in the length direction of the exterior member. Therefore, it is possible to restrict the positional deviation of the path restricting member with respect to the exterior member in the length direction of the exterior member. As a result, it is possible to improve the positional accuracy of the path restricting member with respect to the exterior member, and to improve the positional accuracy of the path restricting member with respect to the wire harness main body. Therefore, the path restricting member can appropriately restrict the path of the wire harness main body at a desired position.

[0010] [2] The movement restricting member is a cable tie having a band portion extending in a first direction along the circumferential direction of the exterior member, having a thickness in a second direction along the radial direction of the exterior member, and having a width in a third direction along the length direction of the exterior member, and a lock portion integral with the band portion and provided at a first end of the band portion in the first direction, and the band portion has a first end face facing the outer surface of the exterior member in the second direction and a second end face provided on the opposite side of the first end face in the second direction, and the first engagement portion is preferably a convex portion protruding from the first end face toward the exterior member. According to this configuration, the cable tie having the band portion and the lock portion can restrict the relative movement of the path restricting member with respect to the exterior member in the length direction of the exterior member. In the cable tie, the band portion can be easily wrapped around the outer periphery of the exterior member, thereby improving the assembling workability of the wire harness. Furthermore, the protrusion provided on the first end surface of the band portion fits into the annular recess, so that the protrusion and the exterior member are engaged with each other in the length direction of the exterior member, thereby making it possible to suitably suppress relative movement of the movement restricting member with respect to the exterior member in the length direction of the exterior member.

[0011] [3] In the third direction, it is preferable that the size of the band portion is larger than the size of the convex portion, and the band portion is formed to a size that cannot be fitted into the annular concave portion. According to this configuration, since the band portion is formed to a size that cannot be fitted into the annular concave portion, the first end face of the band portion can be brought into contact with the outer surface of the exterior member, specifically the outer surface of the annular convex portion. This makes it easy to position the movement restricting member in the radial direction of the exterior member, and allows the band portion to be stably wrapped around the outer surface of the exterior member.

[0012] [4] It is preferable that the band portion has a third end face facing the end face in the length direction of the path regulating member in the third direction and a fourth end face provided on the opposite side to the third end face in the third direction, and the second engagement portion is the third end face. According to this configuration, the end face in the length direction of the path regulating member is engaged with the third end face of the band portion in the length direction of the exterior member. This suppresses relative movement of the path regulating member with respect to the exterior member and the movement suppressing member in the length direction of the exterior member. Therefore, it is possible to suppress positional deviation of the path regulating member with respect to the exterior member in the length direction of the exterior member.

[0013] [5] It is preferable that the movement restricting member has a protrusion that protrudes outward from the band portion beyond the third end face of the band portion in the third direction, and the protrusion is capable of contacting the outer surface of the path restricting member. According to this configuration, the movement restricting member is provided with a protrusion that protrudes outward from the third end face of the band portion and is capable of contacting the outer surface of the path restricting member. This protrusion can cover the path restricting member from the outside. For this reason, for example, the path restricting member can be suitably prevented from moving over the movement restricting member in the length direction of the exterior member. Therefore, it is possible to suitably prevent the path restricting member from being displaced relative to the exterior member in the length direction of the exterior member.

[0014] [6] The protrusion extends along the third direction and has a base end that is one end in the third direction and is connected to the band portion, and a tip end that is provided on the opposite side of the base end in the third direction, and the protrusion is preferably elastically deformable so that the tip end is displaced in the second direction relative to the base end. According to this configuration, the tip end of the protrusion is elastically deformable so that it is displaced in the second direction relative to the base end of the protrusion. For this reason, even if the external size of the path regulating member is changed, for example, the elastic deformation amount of the protrusion can be changed so that the tip end of the protrusion can be suitably brought into contact with the external surface of the path regulating member. In other words, by changing the elastic deformation amount of the protrusion, one type of movement regulating member can be used in common for multiple types of path regulating members having different external sizes.

[0015] [7] The movement restricting member preferably has a plurality of the protrusions, and the plurality of protrusions are preferably provided at intervals from one another in the first direction of the band portion. According to this configuration, the outer surface of the path restricting member is covered by the plurality of protrusions provided at intervals from one another in the first direction of the band portion. Therefore, the outer surface of the path restricting member can be covered by the plurality of protrusions over a wide range in the circumferential direction of the exterior member. This makes it possible to more suitably prevent, for example, the path restricting member from climbing over the movement restricting member and moving in the length direction of the exterior member. Therefore, it is possible to more suitably prevent the path restricting member from being displaced relative to the exterior member in the length direction of the exterior member.

[0016] [8] It is preferable that the tip end of the protrusion has a wide portion having a dimension larger than the base end of the protrusion along the first direction, and the wide portion is capable of contacting the outer surface of the path regulating member. According to this configuration, the outer surface of the path regulating member is covered by the wide portion. Therefore, the outer surface of the path regulating member can be covered by the wide portion over a wide range in the circumferential direction of the exterior member. This makes it possible to more suitably prevent, for example, the path regulating member from climbing over the movement restricting member and moving in the length direction of the exterior member. Therefore, it is possible to more suitably prevent the path regulating member from being displaced relative to the exterior member in the length direction of the exterior member.

[0017] [9] When the protrusion is the first protrusion, it is preferable that the movement restricting member has a second protrusion that protrudes outward from the band portion in the third direction beyond the fourth end face of the band portion, and the second protrusion extends in the opposite direction to the first protrusion in the third direction and is capable of contacting the outer surface of the path restricting member. According to this configuration, a first protrusion and a second protrusion are provided that protrude on both sides of the band portion in the third direction. Therefore, when the movement restricting member is attached to the outer periphery of the exterior member, the restriction on the orientation of the band portion in the third direction can be eliminated. For example, even if the movement restricting member is attached to the outer surface of the exterior member so that the fourth end face of the band portion faces the end face in the length direction of the path restricting member, the second protrusion can be brought into contact with the outer surface of the path restricting member. This improves the ease of installation of the movement restricting member, and thus improves the ease of assembly of the wire harness.

[0018]

[10] The band portion has the first end to which the lock portion is connected and a second end provided on the opposite side of the first end in the first direction, the second end has a plurality of third engagement portions provided at intervals in the first direction of the band portion, the lock portion has an insertion hole into which the second end of the band portion can be inserted and a fourth engagement portion provided on the inner surface of the insertion hole and engageable with the third engagement portion, and it is preferable that the first engagement portion is not provided on the second end. According to this configuration, the band portion can be locked to the lock portion by inserting the second end of the band portion into the insertion hole of the lock portion and engaging the fourth engagement portion of the lock portion with one of the third engagement portions. At this time, the size of the inner circumference of the movement restricting member can be matched to the size of the outer shape of the exterior member by changing the degree of insertion of the band portion into the lock portion. In other words, one type of movement restricting member can be used for multiple types of exterior members having different outer shapes by adjusting the degree of insertion of the band portion into the lock portion. Furthermore, the first engagement portion is not provided at the second end of the band portion where the third engagement portion is provided, which prevents the first engagement portion from interfering with the engagement between the third engagement portion and the fourth engagement portion.

[0019] [Details of the embodiment of the present disclosure] Specific examples of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, some of the configurations may be exaggerated or simplified. In addition, the dimensional ratio of each part may differ in each drawing. In this specification, "orthogonal" does not only mean strictly orthogonal, but also includes roughly orthogonal within the scope of the action and effect of this embodiment. In addition, "cylindrical" as used in the description of this specification includes not only those in which a peripheral wall is formed continuously around the entire circumference, but also those in which a plurality of parts are combined to form a cylindrical shape, and those having a notch in a part of the circumference such as a C-shape. The shape of "cylindrical" includes, but is not limited to, a circle, an ellipse, and a polygon with sharp or rounded corners. In addition, the term "annular" as used in the description of this specification may refer to any structure that forms a loop, or a continuous shape without ends, as well as a generally loop-shaped structure with a gap such as a C-shape. In addition, the shape of "annular" includes, but is not limited to, a circle, an ellipse, and a polygon with sharp or rounded corners. In addition, "facing" in this specification refers to surfaces or members being in front of each other, and includes not only the case where they are completely in front of each other, but also the case where they are partially in front of each other. In addition, in this specification, "facing" includes both the case where a member other than the two parts is interposed between the two parts, and the case where nothing is interposed between the two parts. Note that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0020] (Overall configuration of the wire harness 10) A wire harness 10 shown in FIG. 1 is mounted on a vehicle V such as a hybrid vehicle or an electric vehicle. The wire harness 10 electrically connects two or more in-vehicle devices to each other. The in-vehicle devices are electrical devices mounted on the vehicle V. The wire harness 10 electrically connects, for example, an inverter M1 installed at the front of the vehicle V and a high-voltage battery M2 installed behind the inverter M1 on the vehicle V. The wire harness 10 is formed in an elongated shape so as to extend, for example, in the front-rear direction of the vehicle V. The wire harness 10 is routed in the vehicle V so that, for example, a middle portion of the length of the wire harness 10 passes outside the passenger compartment, such as under the floor of the vehicle V.

[0021] The inverter M1 is connected to, for example, a wheel drive motor (not shown) that serves as a power source for driving the vehicle. The inverter M1 generates AC power from DC power of a high-voltage battery M2 and supplies the AC power to the motor. The high-voltage battery M2 is, for example, a battery capable of supplying a voltage of several hundred volts.

[0022] The wire harness 10 has a wire harness main body 11. The wire harness main body 11 has an electric wire member 20 and a cylindrical exterior member 30 that surrounds the outer periphery of the electric wire member 20. The wire harness 10 has connectors C1, C2 attached to both ends of the electric wire member 20. One end in the length direction of the electric wire member 20 is connected to the inverter M1 via the connector C1, and the other end in the length direction of the electric wire member 20 is connected to the high-voltage battery M2 via the connector C2.

[0023] 2 and 3, the wire harness 10 has a path regulating member 40 attached to the outer periphery of the exterior member 30, and a path regulating member 50 attached to the outer periphery of the exterior member 30. Each of the path regulating members 40, 50 regulates a route along which the wire harness main body 11 is routed. The wire harness 10 has a movement regulating member 70 that regulates movement of the path regulating member 40. Note that the path regulating members 40, 50 and the movement regulating member 70 are not shown in FIG. 1.

[0024] (Configuration of the electric wire member 20) As shown in FIGS. 4 and 5, the electric wire member 20 has, for example, one or more electric wires 21 (two in this embodiment) and a braided member 25 that collectively surrounds the outer periphery of the multiple electric wires 21.

[0025] As shown in Fig. 4, each electric wire 21 is a covered electric wire having a conductive core wire 22 and an insulating covering 23 that surrounds the outer periphery of the core wire 22 and has insulating properties. Each electric wire 21 is, for example, a high-tension electric wire that can handle high voltage and large current. Each electric wire 21 may be, for example, a non-shielded electric wire that does not have an electromagnetic shield structure itself, or a shielded electric wire that has an electromagnetic shield structure itself. Each electric wire 21 in this embodiment is a non-shielded electric wire.

[0026] The core wire 22 may be, for example, a stranded wire made of a plurality of metal wires stranded together, or a single core wire made of a single conductor. The single core wire may be, for example, a columnar conductor made of a single metal rod having a solid interior structure, or a tubular conductor having a hollow interior structure. The core wire 22 may be a combination of a stranded wire, a columnar conductor, and a tubular conductor. The material of the core wire 22 may be, for example, a copper-based or aluminum-based metal material.

[0027] The insulating coating 23, for example, covers the entire outer circumferential surface of the core wire 22. The insulating coating 23 is made of, for example, a resin material having insulating properties. The cross-sectional shape of each electric wire 21 cut by a plane perpendicular to the length direction of each electric wire 21, that is, the transverse cross-sectional shape of each electric wire 21, can be formed into any shape. The transverse cross-sectional shape of each electric wire 21 is formed into, for example, a circular shape, a semicircular shape, a polygonal shape, a square shape, a flat shape, or the like. The transverse cross-sectional shape of each electric wire 21 in this embodiment is formed into a circular shape.

[0028] The braided member 25 has, for example, a cylindrical shape that collectively surrounds the outer circumference of the plurality of electric wires 21. As the braided member 25, for example, a braided wire in which a plurality of metal wires are woven, or a braided wire in which metal wires and resin wires are combined and woven, can be used. As the material of the metal wires, for example, a copper-based or aluminum-based metal material can be used. Although not shown in the drawings, both ends of the braided member 25 in the length direction are earthed, for example, by connectors C1 and C2 (see FIG. 1).

[0029] (Configuration of exterior member 30) The exterior member 30 has a tubular shape surrounding the outer periphery of the electric wire member 20 over the entire circumferential direction. The exterior member 30 of this embodiment is formed in a cylindrical shape. For example, the exterior member 30 has a peripheral wall formed continuously over the entire circumferential direction of the exterior member 30. For example, the exterior member 30 is sealed over the entire circumferential direction of the exterior member 30. The exterior member 30 has a function of protecting the electric wire member 20 from flying objects and water droplets, for example.

[0030] The exterior member 30 has, for example, flexibility and can be easily bent. Examples of the flexible exterior member 30 include a corrugated tube made of resin and a waterproof cover made of rubber.

[0031] As shown in FIG. 5, the exterior member 30 of this embodiment is a corrugated tube made of resin and has a bellows shape with diameters that repeatedly increase and decrease in the length direction of the exterior member 30. That is, the exterior member 30 of this embodiment has a bellows structure in which annular convex portions 31 and annular concave portions 32 are alternately arranged along the length direction of the exterior member 30. Each of the annular convex portions 31 and the annular concave portions 32 forms, for example, a ring that goes around once along the circumferential direction of the exterior member 30. As the material of the exterior member 30, for example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin can be used. In addition, in FIG. 1 to FIG. 3, the exterior member 30 is illustrated in a simplified form in order to simplify the drawings.

[0032] (Configuration of path regulating members 40 and 50) As shown in FIG. 2 and FIG. 3, each of the path regulating members 40, 50 holds the exterior member 30. Each of the path regulating members 40, 50 is, for example, harder than the exterior member 30. Each of the path regulating members 40, 50 has a hardness that makes it difficult to bend in a direction perpendicular to the length direction of the wire harness main body 11 compared to the exterior member 30. As a result, each of the path regulating members 40, 50 regulates the path of the wire harness main body 11. For example, each of the path regulating members 40, 50 assists the exterior member 30 so that the wire harness main body 11 does not bend due to its own weight or the like and deviate from a desired path. Each of the path regulating members 40, 50 is provided partially in the length direction of the wire harness main body 11. Note that each of the path regulating members 40, 50 is provided in a single or multiple number depending on the path of the wire harness main body 11.

[0033] The path regulating 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 path regulating member 40 regulates the path of the wire harness main body 11 at the straight portion 11A. Here, the straight portion 11A is a portion where the path of the wire harness main body 11 extends linearly in one direction. The path regulating 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 path regulating member 50 regulates the path of the wire harness main body 11 at the bent portion 11B. Here, the bent portion 11B is a portion where the path of the wire harness main body 11 is bent in a two-dimensional or three-dimensional manner.

[0034] (Configuration of the path regulating member 40) As shown in FIG. 4, the path regulating member 40 covers a part of the outer periphery of the exterior member 30 in the circumferential direction of the exterior member 30. The path regulating member 40 is tubular and covers the outer periphery of the exterior member 30 in a part of the circumferential direction of the exterior member 30. The path regulating member 40 covers, for example, a range larger than half of the outer periphery of the exterior member 30. That is, the path regulating member 40 covers, for example, a range larger than half of the entire circumferential direction of the exterior member 30 in the outer periphery of the exterior member 30. The cross-sectional shape of the path regulating member 40 is generally C-shaped. The cross-sectional shape of the path regulating member 40 is uniform over the entire length of the path regulating member 40 in the length direction, for example. As shown in FIG. 3, the path regulating member 40 extends along the path of the straight portion 11A and is formed in a shape that extends linearly in one direction.

[0035] The path regulating member 40 is made of, for example, metal or resin. The path regulating member 40 of the present embodiment is made of resin. As the material of the path regulating member 40, for example, synthetic resin such as polypropylene, polyamide, polyacetal, etc. The path regulating member 40 can be manufactured by a well-known manufacturing method such as extrusion molding or injection molding.

[0036] The path regulating member 40 has an insertion opening 40X that opens in a direction perpendicular to the length direction of the path regulating member 40. The path regulating member 40 has an end portion 41 and an end portion 42 that are both ends of the path regulating member 40 in the circumferential direction and form the insertion opening 40X. The path regulating member 40 has a connecting portion 43 that connects the end portion 41 and the end portion 42. In other words, the path regulating member 40 has the connecting portion 43 that covers a part of the exterior member 30 in the circumferential direction, the end portion 41 and the end portion 42 that are provided at both ends of the connecting portion 43, and the insertion opening 40X formed by the end portion 41 and the end portion 42.

[0037] 4, the connecting portion 43 constitutes a main portion of the path regulating member 40. The radial thickness of the connecting portion 43 is, for example, uniform in the circumferential direction of the path regulating member 40. The cross-sectional shape of the connecting portion 43 is, for example, formed into a shape that follows the outer surface of the exterior member 30. The cross-sectional shape of the end portion 41, the end portion 42, and the connecting portion 43 is, for example, formed into an arc shape.

[0038] The end portion 41 and the end portion 42 are provided on opposite sides of the path regulating member 40 in the circumferential direction. The end portion 41 and the end portion 42 are provided apart from each other in the circumferential direction of the path regulating member 40 with the insertion opening 40X therebetween. In other words, a gap between the end portion 41 and the end portion 42 in the circumferential direction of the path regulating member 40 is configured as the insertion opening 40X. In this manner, the path regulating member 40 is formed in a C-shape having the insertion opening 40X at a part of the circumferential direction of the path regulating member 40.

[0039] The end portion 41 has a tip 41A. The end portion 42 has a tip 42A. The tips 41A, 42A form the insertion opening 40X. In other words, the tips 41A, 42A form the inner surface of the insertion opening 40X. The tips 41A, 42A are formed in a curved shape, for example, when viewed from the longitudinal direction of the path regulating member 40. That is, the cross-sectional shape of the tips 41A, 42A is formed in a curved shape. The cross-sectional shape of the tips 41A, 42A in this embodiment is formed in a semicircular shape.

[0040] The path regulating member 40 has, for example, protruding portions 45 protruding from the inner surfaces of the end portions 41 and 42. Each protruding portion 45 protrudes toward the exterior member 30 inserted inside the path regulating member 40 and can contact the outer surface of the exterior member 30. Each protruding portion 45 contacts, for example, the outer surface of the annular convex portion 31 of the exterior member 30. Each protruding portion 45 protrudes, for example, from the inner surfaces of the tips 41A and 42A. The cross-sectional shape of each protruding portion 45 is formed, for example, in a curved shape. The cross-sectional shape of each protruding portion 45 of this embodiment is formed in a semicircular shape. Each protruding portion 45 extends in the length direction of the path regulating member 40. Each protruding portion 45 extends, for example, over the entire length of the path regulating member 40 in the length direction.

[0041] Each protrusion 45, for example, presses the exterior member 30 from the outside of the exterior member 30. The exterior member 30 is, for example, elastically sandwiched between the two protrusions 45 and the connecting portion 43. This makes the connection of the path regulating member 40 to the exterior member 30 strong. Therefore, the path regulating member 40 attached to the outer periphery of the exterior member 30 is suppressed from moving in the length direction of the exterior member 30.

[0042] An opening width of the insertion opening 40X, i.e., the shortest distance between the end 41 and the end 42, is smaller than, for example, the outer diameter of the exterior member 30. As shown in Fig. 3, the insertion opening 40X extends along the longitudinal direction of the path regulating member 40. The insertion opening 40X extends over the entire longitudinal length of the path regulating member 40. In other words, the insertion opening 40X is formed so as to open in a direction perpendicular to the longitudinal direction of the path regulating member 40 and to open at both ends of the path regulating member 40 in the longitudinal direction.

[0043] By inserting the exterior member 30 into the insertion opening 40X from a direction perpendicular to the length direction of the path regulating member 40, the path regulating member 40 is elastically deformed, and the opening width of the insertion opening 40X becomes larger. When the exterior member 30 is inserted inside the path regulating member 40, the path regulating member 40 elastically returns to its original shape. As a result, the opening width of the insertion opening 40X becomes smaller than the outer diameter of the exterior member 30, and the path regulating member 40 is attached to the outer periphery of the exterior member 30.

[0044] The path regulating member 40 has an end portion 47 and an end portion 48 which are both ends in the length direction of the path regulating member 40. The end portion 48 has an end face 48A of the path regulating member 40 in the length direction. (Configuration of the path regulating member 50) 2 and 3, the path regulating member 50 is bent along the shape of the bending portion 11B. The path regulating member 50 is made of, for example, metal or resin. The path regulating member 50 of the present embodiment is made of resin. As the material of the path regulating member 50, for example, synthetic resin such as polypropylene, polyamide, polyacetal, etc. can be used. The path regulating member 50 can be manufactured by, for example, injection molding, etc.

[0045] The path regulating member 50 has a main body portion 51 and a covering portion 60 that covers a portion of the path regulating member 40 in the longitudinal direction. The main body portion 51 has, for example, a bent shape bent along the path 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, approximately half of the outer periphery of the exterior member 30. The main body portion 51 has, for example, a substantially semi-cylindrical shape.

[0046] The main body 51 has an end 53 and an end 54, which are both ends in the circumferential direction of the main body 51. The main body 51 has an insertion opening 51X formed by the end 53 and the end 54. The insertion opening 51X is an opening between the end 53 and the end 54. The insertion opening 51X opens in a direction perpendicular to the longitudinal direction of the path regulating member 50. The insertion opening 51X extends over the entire length of the path regulating member 50 in the longitudinal direction. The opening width of the insertion opening 51X, that is, the shortest distance between the end 53 and the end 54, is, for example, equal to the outer diameter of the exterior member 30 or larger than the outer diameter of the exterior member 30. The exterior member 30 and the path regulating member 40 are inserted into the insertion opening 51X along a direction perpendicular to the longitudinal direction of the path regulating member 50.

[0047] The covering portion 60 is provided, for example, at one end in the longitudinal direction of the path regulating member 50. The covering portion 60 covers, for example, the outer periphery of the end portion 47 of the path regulating member 40. The covering portion 60 has a covering main body portion 61 which is an end portion in the longitudinal direction of the main body portion 51, and a lid portion 62 connected to the covering main body portion 61. The covering main body portion 61 is a part of the main body portion 51. The lid portion 62 is, for example, formed integrally with the covering main body portion 61. The cross-sectional shape of the inner surface of the lid portion 62 is formed, for example, in a shape that follows the outer surface of the exterior member 30. The lid portion 62 is formed, for example, in a substantially semi-elliptical cylindrical shape.

[0048] 3, the lid portion 62 partially covers the insertion opening 51X of the main body portion 51 in the length direction of the path regulating member 50. For example, the lid portion 62 covers the insertion opening 51X only in the covering main body portion 61 in the length direction of the main body portion 51.

[0049] The covering portion 60 has, for example, a hinge portion 63 connecting the covering main body portion 61 and the lid portion 62. The hinge portion 63 connects one circumferential end of the covering main body portion 61 and one circumferential end of the lid portion 62. One or more lock portions 64 are provided at the other circumferential end of the covering main body portion 61. One or more claw portions 65 are provided at the other circumferential end of the lid portion 62.

[0050] The lid portion 62 can rotate about the hinge portion 63 between an open position shown in FIG. 3 and a closed position shown in FIG. 2. As shown in FIG. 4, when the lid portion 62 is in the closed position, the claw portion 65 is hooked on the lock portion 64. This holds the lid portion 62 in the closed position. In this manner, the covering body portion 61 and the lid portion 62 are connected to each other. When the covering body portion 61 and the lid portion 62 are connected to each other, the covering portion 60 forms a ring shape that collectively surrounds the outer periphery of the exterior member 30 and the end portion 47 of the path regulating member 40. When in the closed position, the lid portion 62 covers the insertion opening 51X in the covering body portion 61 and the insertion opening 40X in the end portion 47.

[0051] (Configuration of movement restricting member 70) As shown in Fig. 2, the movement restricting member 70 is attached to the outer periphery of the exterior member 30. The movement restricting member 70 restricts the relative movement of the path restricting member 40 with respect to the exterior member 30 in the length direction of the exterior member 30. The movement restricting member 70 is provided in the vicinity of the end portion 48 of the path restricting member 40 in the length direction of the wire harness main body 11. The movement restricting member 70 is, for example, a metal or resin cable tie. The movement restricting member 70 in this embodiment is a resin cable tie. Examples of materials that can be used for the movement restricting member 70 include polypropylene, polyether ether ketone, and fluororesin.

[0052] The movement restricting member 70 has a band portion 80 and a lock portion 85 provided at one end in the longitudinal direction of the band portion 80. The movement restricting member 70 is, for example, a single component in which the band portion 80 and the lock portion 85 are integrally formed.

[0053] The band portion 80 is formed into a long and narrow flat plate shape with a rectangular cross section as a whole. The band portion 80 is wrapped around the outer surface of the exterior member 30. The band portion 80 extends in a first direction L along the circumferential direction of the exterior member 30, has a thickness in a second direction T along the radial direction of the exterior member 30, and has a width in a third direction W along the length direction of the exterior member 30.

[0054] The band portion 80 has a first end 81 and a second end 82, which are both ends of the band portion 80 in the first direction L. The first end 81 is connected to the lock portion 85. The second end 82 is provided on the opposite side of the band portion 80 from the first end 81 in the first direction L. The band portion 80 has a first end face 80A and a second end face 80B, which are both end faces of the band portion 80 in the second direction T, and a third end face 80C and a fourth end face 80D, which are both end faces of the band portion 80 in the third direction W. When the band portion 80 is wrapped around the outer surface of the exterior member 30, the first end face 80A is an inner face facing the outer surface of the exterior member 30, and the second end face 80B is an outer face provided on the opposite side of the first end face 80A in the second direction T. When the band portion 80 is wrapped around the outer surface of the exterior member 30, the third end face 80C is an end face opposite the longitudinal end face 48A of the path regulating member 40, and the fourth end face 80D is an end face provided on the opposite side to the third end face 80C in the third direction W.

[0055] As shown in FIG. 5, the cross-sectional shape of the band portion 80 is, for example, rectangular. The band portion 80 is, for example, formed to have a size such that it cannot be fitted into the annular recess 32. For example, the dimension of the band portion 80 along the third direction W is, for example, formed to have a size such that it cannot be fitted into the annular recess 32. The dimension of the band portion 80 along the second direction T (i.e., the thickness of the band portion 80) is, for example, smaller than the dimension of the path regulating member 40 along the second direction T (i.e., the thickness of the path regulating member 40). The thickness of the band portion 80 may be equal to or greater than the thickness of the path regulating member 40.

[0056] As shown in FIG. 6, the band portion 80 has a plurality of engagement grooves 83. Each engagement groove 83 is provided, for example, in the second end surface 80B at the second end portion 82. Each engagement groove 83 is formed so as to be recessed from the second end surface 80B. Each engagement groove 83 extends along the third direction W of the band portion 80. The plurality of engagement grooves 83 are provided at intervals from each other in the first direction L of the band portion 80. The plurality of engagement grooves 83 are provided, for example, only in the second end portion 82 in the first direction L of the band portion 80. In other words, in the movement restricting member 70 of this embodiment, the portion of the band portion 80 in the first direction L where the engagement grooves 83 are formed is referred to as the second end portion 82.

[0057] 5, the movement restricting member 70 has a protrusion 90 as a first engagement portion. The protrusion 90 is provided, for example, on a first end surface 80A of the band portion 80. The protrusion 90 protrudes from the first end surface 80A of the band portion 80 toward the exterior member 30. The protrusion 90 protrudes from the first end surface 80A of the band portion 80 along the second direction T. The cross-sectional shape of the protrusion 90 is, for example, rectangular.

[0058] The protrusion 90 is formed so as to be able to fit into the annular recess 32 of the exterior member 30. By fitting into the annular recess 32, the protrusion 90 engages with the inner side surface of the annular recess 32 or the side surface of the annular protrusion 31 in the length direction of the exterior member 30. This restricts relative movement of the movement restricting member 70 with respect to the exterior member 30 in the length direction of the exterior member 30.

[0059] As shown in Figures 6 and 7, the convex portion 90 extends, for example, along the first direction L of the band portion 80. The convex portion 90 is provided, for example, partially in the first direction L of the band portion 80. The convex portion 90 is provided, for example, in a middle portion of the band portion 80 in the first direction L. The convex portion 90 is not provided at the second end portion 82 of the band portion 80. That is, the convex portion 90 is not provided at the first end face 80A of the band portion 80 in the first direction L where the engagement groove 83 is provided. The convex portion 90 is not provided, for example, at the first end portion 81 of the band portion 80.

[0060] The protrusion 90 is, for example, partially provided in the third direction W of the band portion 80. The protrusion 90 has, for example, a width extending in the third direction W of the band portion 80. The dimension of the protrusion 90 along the third direction W is smaller than the dimension of the band portion 80 along the third direction W. As shown in FIG. 5 , the dimension of the protrusion 90 along the third direction W is formed to be large enough to fit into the annular recess 32.

[0061] As shown in FIG. 6, the movement restricting member 70 has, for example, one or more (three in this embodiment) first protrusions 91 and one or more (three in this embodiment) second protrusions 92. Each first protrusion 91 protrudes outward (outward) from the band part 80 in the third direction W beyond the third end face 80C. Each first protrusion 91 protrudes leftward in the figure beyond the third end face 80C in the third direction W. Each second protrusion 92 protrudes outward from the band part 80 in the third direction W beyond the fourth end face 80D. Each second protrusion 92 protrudes rightward in the figure beyond the fourth end face 80D in the third direction W. The first protrusions 91 are provided at intervals from each other in the first direction L of the band part 80. The second protrusions 92 are provided at intervals from each other in the first direction L of the band part 80. The first protrusions 91 and the second protrusions 92 are provided at different positions from each other in the first direction L of the band portion 80. For example, a plurality of first protrusions 91 and a plurality of second protrusions 92 are provided alternately in the first direction L of the band portion 80. The first protrusions 91 and the second protrusions 92 are not provided at the second end 82 of the band portion 80.

[0062] Each of the first protrusions 91 extends along the third direction W. Each of the first protrusions 91 has a base end 91A connected to the band portion 80 and a tip end 91B provided on the opposite side of the base end 91A in the third direction W. Each of the first protrusions 91 is formed in a cantilever shape with the base end 91A as a fixed end and the tip end 91B as a free end. Each of the first protrusions 91 has spring properties. Each of the first protrusions 91 is configured to be elastically deformable so that the tip end 91B is displaced in the second direction T relative to the base end 91A. Each of the first protrusions 91 is configured to be able to bend in the second direction T due to elastic deformation, for example.

[0063] 5, a base end 91A of each first protrusion 91 is connected to, for example, the second end surface 80B of the band portion 80. The base end 91A protrudes, for example, from the second end surface 80B of the band portion 80 in the second direction T. The base end 91A is, for example, formed integrally and continuously with the band portion 80.

[0064] 6, the tip end 91B of each first protrusion 91 has, for example, a wide portion 91C. The wide portion 91C is formed to have a width along the first direction L that is wider than the first protrusion 91 in a portion other than the wide portion 91C. The dimension of the wide portion 91C along the first direction L is greater than the dimension of the base end 91A along the first direction L. The tip end surface of the tip end 91B is provided at a position farther from the third end surface 80C than the side surface of the lock portion 85, for example.

[0065] 5, the tip portion 91B of each first protrusion 91 can come into contact with the outer surface of the path regulating member 40. For example, the wide portion 91C of the tip portion 91B can come into contact with the outer surface of the path regulating member 40. For example, of both end faces of the tip portion 91B in the second direction T, the end face facing the exterior member 30 comes into contact with the outer surface of the path regulating member 40. The tip portion 91B comes into contact with, for example, the outer surface of the end portion 48 of the path regulating member 40. For example, when the thickness of the band portion 80 is thinner than the thickness of the path regulating member 40, the first protrusion 91 comes into contact with the outer surface of the path regulating member 40 with the tip portion 91B in an elastically deformed state.

[0066] 6, each second protrusion 92 has a similar structure to the first protrusion 91 except that the protrusion direction is opposite to that of each first protrusion 91, and therefore a detailed description thereof will be omitted here. Each second protrusion 92 extends in the opposite direction to the first protrusion 91 in the third direction W. Each second protrusion 92 has a base end 92A similar to the base end 91A, a tip end 92B similar to the tip end 91B, and a wide portion 92C similar to the wide portion 91C.

[0067] The locking portion 85 is formed, for example, to have a larger cross-sectional shape than the band portion 80. For example, the locking portion 85 protrudes outward from the third end face 80C and the fourth end face 80D of the band portion 80 in the third direction W. As shown in Fig. 2, the locking portion 85 protrudes outward from the second end face 80B of the band portion 80 in the second direction T. The locking portion 85 is formed, for example, in a rectangular parallelepiped shape.

[0068] As shown in FIG. 5, the locking portion 85 has an insertion hole 86 into which the band portion 80 can be inserted. The insertion hole 86 is formed so that, for example, the second end 82 of the band portion 80 can be inserted. For example, an engagement claw 87 is provided on the inner surface of the insertion hole 86. The engagement claw 87 is formed so as to be able to engage with an engagement groove 83 provided in the band portion 80. In the movement restricting member 70, the band portion 80 is locked to the locking portion 85 by engaging the engagement claw 87 of the locking portion 85 with one of the multiple engagement grooves 83 provided in the band portion 80. In the movement restricting member 70, for example, the size of the inner circumference of the movement restricting member 70 can be changed by adjusting the degree of insertion of the band portion 80 into the locking portion 85. Therefore, the size of the inner circumference of the movement restricting member 70 can be adjusted to the size of the outer circumference of the exterior member 30 by adjusting the degree of insertion of the band portion 80 into the locking portion 85. Furthermore, in the movement restricting member 70, the degree to which the band portion 80 fastens the exterior member 30 can be adjusted according to the degree to which the band portion 80 is inserted into the lock portion 85, for example.

[0069] The movement restricting member 70 is wound around the outer periphery of the exterior member 30 in a state where the second end 82 of the band portion 80 is inserted into the insertion hole 86 of the lock portion 85. The movement restricting member 70 is provided, for example, so that the band portion 80 is adjacent to the end face 48A of the path restricting member 40 in the longitudinal direction of the exterior member 30. At this time, the third end face 80C of the band portion 80 faces the end face 48A in the longitudinal direction of the exterior member 30 and can be engaged with the end face 48A. The band portion 80 is wound around the outer periphery of the exterior member 30 so that the convex portion 90 provided on the first end face 80A of the band portion 80 fits into the annular recess 32 of the exterior member 30. The band portion 80 is wound around the outer periphery of the exterior member 30 so that the first end face 80A exposed from the convex portion 90 contacts the outer surface of the annular convex portion 31. At this time, the band portion 80 is wound around the outer periphery of the exterior member 30 such that, for example, the tip portion 91B of each first protrusion 91 overlaps with the path regulating member 40 in the radial direction of the exterior member 30. Each first protrusion 91 is in contact with the outer surface of the end portion 48 of the path regulating member 40 in a state in which it is elastically deformed so as to bend radially outward of the exterior member 30 in the second direction T. For example, each first protrusion 91 is provided so as to press the path regulating member 40 from the outside of the path regulating member 40. Note that the lock portion 85 is provided, for example, in a portion corresponding to the insertion opening 40X of the path regulating member 40 in the circumferential direction of the exterior member 30.

[0070] (Configuration of the regulating member 100) As shown in FIG. 2, the wire harness 10 has a restricting member 100 that restricts the movement of the path regulating member 50 relative to the exterior member 30. For example, a resin or metal cable tie, a crimping ring, or an adhesive tape can be used as the restricting member 100. The restricting member 100 in this embodiment is an adhesive tape. The restricting member 100 is formed, for example, so that an end of the path regulating member 50 in the length direction, which is provided on the opposite side to the covering portion 60, is fixed to the outer surface of the exterior member 30. For example, the restricting member 100 is wrapped around the exterior member 30 from the end of the path regulating member 50 in the length direction. This makes it possible to restrict the movement of the path regulating member 50 relative to the exterior member 30 in the length direction and circumferential direction of the wire harness main body 11.

[0071] Next, the operation of this embodiment will be described. A movement restricting member 70 is provided to restrict the relative movement of the path restricting member 40 with respect to the exterior member 30 in the length direction of the exterior member 30. The movement restricting member 70 has a protrusion 90 that fits into the annular recess 32 of the exterior member 30, and has a third end surface 80C that can engage with the end surface 48A in the length direction of the path restricting member 40. According to this configuration, the protrusion 90 of the movement restricting member 70 fits into the annular recess 32 of the exterior member 30, so that the protrusion 90 engages with the inner side surface of the annular recess 32 or the side surface of the annular protrusion 31 in the length direction of the exterior member 30. Therefore, the relative movement of the movement restricting member 70 with respect to the exterior member 30 in the length direction of the exterior member 30 is suppressed. In addition, the third end surface 80C of the movement restricting member 70 is provided to be able to engage with the end surface 48A in the length direction of the path restricting member 40, so that the movement restricting member 70 restricts the movement of the path restricting member 40 in the length direction of the exterior member 30. Therefore, in the length direction of the exterior member 30, the relative movement of the path restriction member 40 with respect to the exterior member 30 and the movement restriction member 70 is suppressed.

[0072] Next, the effects of this embodiment will be described. (1) The movement restricting member 70 is provided, which has a protrusion 90 that fits into the annular recess 32 of the exterior member 30 and a third end surface 80C that can engage with the end surface 48A in the length direction of the path restricting member 40. This configuration provides the above-mentioned effects, and therefore can suppress the movement restricting member 70 from being displaced relative to the exterior member 30 in the length direction of the exterior member 30. Furthermore, the movement restricting member 40 can be suppressed from being displaced relative to the exterior member 30 and the movement restricting member 70 in the length direction of the exterior member 30. Therefore, the positional accuracy of the path restricting member 40 relative to the exterior member 30 can be improved, and thus the positional accuracy of the path restricting member 40 relative to the wire harness main body 11 can be improved. As a result, the path restricting member 40 can be suitably disposed at a desired position of the wire harness main body 11, here, at the straight portion 11A, and the path of the straight portion 11A can be suitably restricted by the path restricting member 40. In other words, the installation position of the path restricting member 40 relative to the wire harness main body 11 can be suitably suppressed from being deviated from the straight portion 11A.

[0073] (2) Furthermore, since movement of the path regulating member 40 in the length direction of the exterior member 30 can be suppressed, detachment of the path regulating member 40 from the path regulating member 50 due to the movement can be suitably suppressed.

[0074] (3) The insertion opening 40X of the path regulating member 40 opens in a direction perpendicular to the longitudinal direction of the path regulating member 40 and extends over the entire longitudinal length of the path regulating member 40. This makes it possible to attach the path regulating member 40 to the exterior member 30 through the insertion opening 40X after performing terminal processing such as attaching the connectors C1, C2 to the longitudinal ends of the electric wire member 20. In this manner, since the path regulating member 40 can be attached later, it is possible to improve the workability of assembling the wire harness 10.

[0075] (4) The movement restricting member 70 is a cable tie having a band portion 80 and a lock portion 85. According to this configuration, the movement restricting member 70, which is a cable tie, can restrict the relative movement of the path restricting member 40 with respect to the exterior member 30 in the length direction of the exterior member 30. With the cable tie, the band portion 80 can be easily wrapped around the outer periphery of the exterior member 30, thereby improving the workability of assembling the wire harness 10.

[0076] (5) The band portion 80 is formed to have a size that prevents it from fitting into the annular recess 32. Therefore, the band portion 80 can be wrapped around the outer surface of the exterior member 30 with the first end surface 80A of the band portion 80 in contact with the outer surface of the exterior member 30, specifically, the outer surface of the annular protrusion 31. This makes it easy to position the movement restricting member 70 in the radial direction of the exterior member 30, and also makes it possible to stably wrap the band portion 80 around the outer surface of the exterior member 30.

[0077] (6) The movement restricting member 70 is provided with a first protruding portion 91 that protrudes outward from the third end surface 80C of the band portion 80 and is capable of contacting the outer surface of the path restricting member 40. The first protruding portion 91 can cover the path restricting member 40 from the outside of the path restricting member 40. This makes it possible to preferably prevent the path restricting member 40 from climbing over the movement restricting member 70 and moving in the length direction of the exterior member 30, for example. This makes it possible to preferably prevent the path restricting member 40 from being misaligned with respect to the exterior member 30 in the length direction of the exterior member 30.

[0078] (7) The first protrusion 91 is elastically deformable such that the tip end 91B is displaced in the second direction T relative to the base end 91A. Therefore, even if the external size of the path regulating member 40 is changed, the tip end 91B of the first protrusion 91 can be suitably brought into contact with the external surface of the path regulating member 40 by changing the amount of elastic deformation of the first protrusion 91. In other words, by changing the amount of elastic deformation of the first protrusion 91, one type of movement regulating member 70 can be used in common for a plurality of types of path regulating members 40 having different external sizes. Here, for example, when the thickness of the path regulating member 40 is changed, the external size of the path regulating member 40 is changed. Therefore, by configuring the first protrusion 91 to be elastically deformable, one type of movement regulating member 70 can be used in common for a plurality of types of path regulating members 40 having different thicknesses.

[0079] (8) The movement restricting member 70 has a plurality of first protrusions 91 provided at intervals from each other in the first direction L of the band portion 80. The tip end 91B of each of the first protrusions 91 has a dimension along the first direction L larger than that of the base end 91A and has a wide portion 91C that can contact the outer surface of the path restricting member 40. According to this configuration, the outer surface of the path restricting member 40 is covered by the wide portions 91C of the plurality of first protrusions 91. Therefore, the path restricting member 40 can be covered from the outside of the path restricting member 40 in the circumferential direction of the exterior member 30, that is, in a wide range in the first direction L. This makes it possible to more suitably suppress, for example, the path restricting member 40 from climbing over the movement restricting member 70 and moving in the length direction of the exterior member 30.

[0080] (9) The movement restricting member 70 has a first protruding portion 91 and a second protruding portion 92 that protrude from both sides of the band portion 80 in the third direction W. Therefore, when the movement restricting member 70 is attached to the outer periphery of the exterior member 30, the restriction on the orientation of the band portion 80 in the third direction W can be eliminated. For example, even if the movement restricting member 70 is attached to the outer surface of the exterior member 30 so that the fourth end surface 80D of the band portion 80 faces the end surface 48A of the path restricting member 40 in the longitudinal direction, the second protruding portion 92 can be brought into contact with the outer surface of the path restricting member 40. This improves the ease of attachment of the movement restricting member 70, and ultimately improves the ease of assembly of the wire harness 10.

[0081] (10) A plurality of engagement grooves 83 are provided on the second end 82 of the band portion 80, and an engagement claw 87 is provided on the inner surface of the insertion hole 86 of the lock portion 85. According to this configuration, the second end 82 of the band portion 80 is inserted into the insertion hole 86 of the lock portion 85, and the engagement claw 87 of the lock portion 85 is engaged with one of the plurality of engagement grooves 83, thereby locking the band portion 80 to the lock portion 85. At this time, by changing the degree of insertion of the band portion 80 into the lock portion 85, the size of the inner circumference of the movement restricting member 70 can be matched to the size of the outer shape of the exterior member 30. In other words, by adjusting the degree of insertion of the band portion 80 into the lock portion 85, one type of movement restricting member 70 can be used in common for a plurality of types of exterior members 30 having different outer shapes.

[0082] (11) The second end 82 of the band portion 80, where the engagement groove 83 is provided, does not have the protrusion 90 in the first direction L. This prevents the engagement between the engagement groove 83 and the engagement claw 87 from being hindered by the protrusion 90.

[0083] (12) The thickness of the band portion 80 is formed to be thinner than the thickness of the path restricting member 40. According to this configuration, an increase in size of the wire harness 10 in the radial direction of the exterior member 30 caused by providing the movement restricting member 70 can be suppressed.

[0084] (13) The path regulating member 40 has the protruding portions 45 that protrude from the inner surfaces of the end portions 41 and 42 and contact the outer surface of the exterior member 30. According to this configuration, for example, the protruding portions 45 press the exterior member 30 from the outside of the exterior member 30. This makes it possible to suitably suppress detachment of the path regulating member 40 from the exterior member 30 through the insertion opening 40X.

[0085] (Other embodiments) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.

[0086] The structure of the movement restricting member 70 in the above embodiment can be modified as appropriate. For example, as long as the movement restricting member 70 has a first engagement portion that fits into the annular recess 32 and a second engagement portion that can engage with the end surface 48A of the path restricting member 40 in the longitudinal direction, other structures are not particularly limited.

[0087] 8, the second protrusion 92 of the movement restricting member 70 may be omitted. The movement restricting member 70 of this modified example has only a first protrusion 91 that protrudes outward beyond the third end surface 80C of the band portion 80.

[0088] 9, for example, the first protrusion 91 and the second protrusion 92 of the movement restricting member 70 may be omitted. Even in this case, the third end surface 80C of the band portion 80 can be engaged with the end surface 48A in the length direction of the path restricting member 40 in the length direction of the exterior member 30. Therefore, it is possible to suppress the path restricting member 40 from being misaligned with respect to the exterior member 30 in the length direction of the exterior member 30.

[0089] 10, the movement restricting member 70 may have a plurality of protrusions 90. For example, a first end surface 80A of the band portion 80 may be provided with a plurality of (here, two) protrusions 90. The plurality of protrusions 90 are provided, for example, at intervals from each other in the third direction W. The plurality of protrusions 90 are formed, for example, so as to be able to fit into different annular recesses 32 from each other. For example, two protrusions 90 are formed so as to be able to fit into two annular recesses 32 adjacent to each other in the length direction of the exterior member 30.

[0090] According to this configuration, the two protrusions 90 are fitted into the two annular recesses 32, respectively, and the two protrusions 90 are engaged with the side surfaces of the annular protrusion 31 in the length direction of the exterior member 30. This makes it possible to suitably suppress the movement of the movement restricting member 70 relative to the exterior member 30 in the length direction of the exterior member 30. Therefore, it is possible to suitably suppress the positional deviation of the movement restricting member 70 relative to the exterior member 30 in the length direction of the exterior member 30.

[0091] In the above embodiment, the cross-sectional shape of the band portion 80 and the protruding portion 90 is T-shaped, but is not limited to this. The cross-sectional shapes of the band portion 80 and the protruding portion 90 can be changed as appropriate. For example, as shown in FIG. 11, the cross-sectional shape of the band portion 80 and the convex portion 90 may be formed in an L-shape. In the movement restricting member 70 of this modified example, the convex portion 90 is provided at the end of the first end face 80A of the band portion 80 on the fourth end face 80D side in the third direction W. For example, one end face of the convex portion 90 in the third direction W is formed flush with the fourth end face 80D of the band portion 80. Even in this case, the convex portion 90 is fitted into the annular recess 32. In addition, the third end face 80C of the band portion 80 is formed so as to be engageable with the end face 48A in the length direction of the path restricting member 40 in the length direction of the exterior member 30. As a result, it is possible to suppress the movement restricting member 70 from being displaced relative to the exterior member 30 in the length direction of the exterior member 30, and to suppress the path restricting member 40 from being displaced relative to the exterior member 30.

[0092] For example, as shown in FIG. 12, the movement restricting member 70 may have a protruding portion 93 that protrudes outward from the third end face 80C of the band portion 80 in the third direction W. The protruding portion 93 protrudes, for example, from the third end face 80C toward one direction (here, rightward) in the third direction W. The protruding portion 93 is, for example, partially provided on the third end face 80C of the band portion 80 in the second direction T. The protruding portion 93 is provided on an end of the third end face 80C of the band portion 80 on the second end face 80B side in the second direction T. For example, one end face of the protruding portion 93 in the second direction T is formed flush with the second end face 80B. The protruding portion 93 is formed so as to extend continuously to a portion other than the second end face 82 (see FIG. 6) of the band portion 80 in the first direction L. The protruding portion 93 is formed so as to be able to come into contact with, for example, the outer surface of the end 48 of the path restricting member 40. The thickness of the band portion 80 in this modified example is formed to be thicker than the thickness of the path regulating member 40. In this modified example, the dimension of the convex portion 90 along the third direction W is equal to the dimension of the band portion 80 along the third direction W.

[0093] According to this configuration, the convex portion 90 is fitted into the annular recess 32, and the third end surface 80C of the band portion 80 is formed to be able to engage with the end surface 48A in the longitudinal direction of the path regulating member 40 in the longitudinal direction of the exterior member 30. As a result, it is possible to suppress the movement regulating member 70 from being displaced relative to the exterior member 30 in the longitudinal direction of the exterior member 30, and it is also possible to suppress the path regulating member 40 from being displaced relative to the exterior member 30. Furthermore, the movement regulating member 70 is provided with a protrusion 93 that contacts the outer surface of the path regulating member 40. Since the protrusion 93 can cover the path regulating member 40 from the outside of the path regulating member 40, it is possible to suitably suppress the path regulating member 40 from climbing over the movement regulating member 70 and moving in the longitudinal direction of the exterior member 30.

[0094] The cross-sectional shape of the band portion 80 and the protrusion 90 may be formed into an I-shape. For example, the protrusion 93 may be omitted from the movement restricting member 70 shown in FIG. For example, as shown in FIG. 13, a protrusion 94 may be provided protruding from the fourth end face 80D of the band portion 80 of the movement restricting member 70 shown in FIG. 12 toward one direction (here, leftward) in the third direction W. The protrusion 94 is provided, for example, partially on the fourth end face 80D of the band portion 80 in the second direction T. The protrusion 94 is provided on an end of the fourth end face 80D of the band portion 80 on the first end face 80A side in the second direction T. For example, one end face of the protrusion 94 in the second direction T is formed flush with the first end face 80A. The protrusion 94 extends, for example, along the first direction L. The protrusion 94 extends, for example, over the entire length of the band portion 80 in the first direction L. The protrusion 94 is formed, for example, so as to be able to come into contact with the outer surface of the annular protrusion 31. The dimension of the protrusion 94 along the second direction T is formed smaller than the dimension of the band portion 80 along the second direction T. For example, the dimension of the protrusion 94 along the second direction T may be equal to the dimension of the band portion 80 along the second direction T, or may be greater than the dimension of the band portion 80 along the second direction T. The protrusion 94 may be a part of the band portion 80.

[0095] Although the protrusions 90 extend continuously along the first direction L of the band portion 80, the present invention is not limited to this. For example, the protrusions 90 may be provided so as to extend intermittently along the first direction L of the band portion 80. In other words, the protrusions 90 may be provided partially at predetermined intervals in the first direction L of the band portion 80.

[0096] The wide portion 91C of the first protruding portion 91 may be omitted. For example, the first protruding portion 91 may be formed so that the width along the first direction L is uniform over the entire length of the first protruding portion 91 in the third direction W. The second protruding portion 92 can also be modified in a similar manner.

[0097] The engagement groove 83 may be provided on the first end surface 80A. In the movement restricting member 70, the third engagement portion of the band portion 80 is the engagement groove 83, and the fourth engagement portion of the lock portion 85 is the engagement claw 87, so that the third engagement portion and the fourth engagement portion engage with each other, but this concave-convex relationship may be reversed.

[0098] The restricting member 100 may be changed to a movement restricting member 70. That is, the movement restricting member 70 may be used as a movement restricting member that restricts the relative movement of the path restricting member 50 with respect to the exterior member 30 in the length direction of the exterior member 30.

[0099] The restricting member 100 may be omitted. Although the movement restricting member 70 has been embodied as a cable tie having the band portion 80 and the lock portion 85, the movement restricting member 70 is not limited to this. For example, the movement restricting member 70 may be changed to a ring member having a fixed size of the inner circumference of the movement restricting member 70.

[0100] The structure of the path regulating member 50 in the above embodiment can be modified as appropriate. For example, the bent shape of the main body portion 51 can be modified as appropriate. For example, the cross-sectional shape of the inner surface of the main body portion 51 can be modified as appropriate.

[0101] In the path regulating member 50, the main body portion 51 (coating main body portion 61) and the lid portion 62 are integrally formed with each other, but this is not limited thereto, and the main body portion 51 and the lid portion 62 may be separate. In other words, the main body portion 51 and the lid portion 62 may be separate parts.

[0102] The cover portion 62 of the path regulating member 50 may be omitted. In the path control member 50, a lid portion connected to the main body portion 51 other than the covering main body portion 61 may be provided.

[0103] The path regulating member 50 may be omitted. In this case, movement regulating members 70 may be provided at both ends 47, 48 of the path regulating member 40 in the longitudinal direction. The structure of the path regulating member 40 in the above embodiment can be modified as appropriate. For example, as long as the path regulating member 40 has an insertion opening 40X and has a structure that allows it to be attached to the outer periphery of the exterior member 30, other structures are not particularly limited.

[0104] Each protrusion 45 may be provided at a position farther away from the insertion opening 40X than the tip 41A of the end portion 41 in the circumferential direction of the path regulating member 40. The protrusions 45 may be provided partially in the longitudinal direction of the path regulating member 40 .

[0105] At least one of the two protrusions 45 may be omitted. The path regulating member 40 may be provided with a second protruding portion that protrudes from the inner surface of the connecting portion 43 and contacts the outer surface of the exterior member 30. With this configuration, it is possible to bring both the protruding portion 45 and the second protruding portion into contact with the outer surface of the exterior member 30. This makes it possible to suppress rattling of the path regulating member 40.

[0106] In the path regulating member 40, a groove extending along the length direction may be provided on the outer surface of the connecting portion 43. With this configuration, the connecting portion 43 can be easily deformed toward the outer periphery from the groove, which makes it possible to easily widen the insertion opening 40X. As a result, this can contribute to improving the assembling of the path regulating member 40.

[0107] The radial thickness of the connecting portion 43 may be configured to vary in the circumferential direction. The cross-sectional shape of the connecting portion 43 is not limited to a circular arc shape, but may be changed to, for example, an elliptical arc shape or a U-shape.

[0108] In the above embodiment, the path regulating members 40, 50 are harder than the exterior member 30, but this is not limiting, and the path regulating members 40, 50 may have a hardness equal to or less than that of the exterior member 30. In other words, the path regulating members 40, 50 do not need to be harder than the exterior member 30 as long as they act to make the wire harness main body 11 less likely to bend than the wire harness main body 11 in a state in which the path regulating members 40, 50 are not attached.

[0109] The exterior member 30 may be, for example, a metal layer containing a metal material provided on the outer surface of a corrugated tube made of resin. In the above embodiment, the exterior member 30 is embodied as a corrugated tube made of resin, but is not limited to this. For example, the exterior member 30 is not limited to a corrugated tube as long as it has a bellows shape in which the annular protrusions 31 and the annular recesses 32 are alternately connected in the length direction of the exterior member 30. In addition, the bellows shape in which the annular protrusions 31 and the annular recesses 32 are alternately connected may be provided only in a portion of the exterior member 30 in the length direction.

[0110] The exterior member 30 may have a slit extending in the longitudinal direction of the exterior member 30 . Although each of the electric wires 21 is a high-voltage electric wire, the present invention is not limited to this. For example, each of the electric wires 21 may be a low-voltage electric wire.

[0111] In the electric wire member 20, the electromagnetic shielding member is embodied as the braided member 25, but is not limited thereto. For example, the electromagnetic shielding member in the electric wire member 20 may be embodied as a metal foil. The braid member 25 in the electric wire member 20 may be omitted.

[0112] Although the electric wire member 20 includes two electric wires 21, the present invention is not limited to this. The number of electric wires 21 may be one, or three or more. The relative positions of the inverter M1 and the high-voltage battery M2 in the vehicle V are not limited to those in the above embodiment, and may be changed as appropriate depending on the vehicle configuration.

[0113] Although the multiple on-board devices electrically connected by the wire harness 10 are embodied as the inverter M1 and the high-voltage battery M2, the multiple on-board devices electrically connected by the wire harness 10 are not limited to this. The multiple on-board devices electrically connected by the wire harness 10 are not particularly limited as long as they are electrical devices mounted on the vehicle V.

[0114] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, not by the above meaning, and is intended to include all modifications within the meaning and scope of the claims.
