Description
[Technical Field]
[0001] The present disclosure relates to a wire harness. [Background technology]
[0002] BACKGROUND ART Conventionally, a wire harness is known that includes an electric wire member and a pipe that covers the outer periphery of the electric wire member to protect the electric wire member and regulate the path of the electric wire member (see, for example, Patent Document 1). The pipe described in Patent Document 1 is composed of a pair of divided bodies, and can be attached from the outside of the electric wire member by placing the electric wire member along one of the divided bodies and then welding the divided bodies together. Therefore, even if the pipe is long, the wire harness does not require the complicated work of passing the electric wire member through the pipe. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-84547 Summary of the Invention [Problem to be solved by the invention]
[0004] However, in the above-described wire harness, the segments must be welded together to form a single unit, which requires, for example, a welding device, making it difficult to manufacture. While it is possible to fix the segments together using a locking structure such as a claw, this would make the structure of the segments more complicated.

[0009] [Description of the 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 to be attached to a vehicle, comprising: an electric wire member; a first path regulating member attached to the electric wire member; and a second path regulating member attached to the first path regulating member, wherein the first path regulating member has a first main body portion covering a part of the outer periphery of the electric wire member; and a first insertion opening formed by both circumferential ends of the first main body portion, opening in a direction perpendicular to the longitudinal direction of the first path regulating member and extending over the entire longitudinal direction of the first path regulating member, and configured to allow the electric wire member to be inserted; and the second path regulating member has a second main body portion covering a part of the outer periphery of the first main body portion and covering the first insertion opening so as to block it; and a second insertion opening formed by both circumferential ends of the second main body portion, opening in a direction perpendicular to the longitudinal direction of the second path regulating member and extending over the entire longitudinal direction of the second path regulating member, and configured to allow the first path regulating member to be inserted.
[0010] According to this configuration, a portion of the outer periphery of the electric wire member is covered by the first main body portion of the first path regulating member. Furthermore, a portion of the outer periphery of the electric wire member that is not covered by the first main body portion and corresponds to the first insertion opening is covered by the second main body portion of the second path regulating member. This covers the entire periphery of the electric wire member, protecting it and restricting its path. The first path regulating member can be attached to the electric wire member through the first insertion opening. The second path regulating member can be attached to the first path regulating member through the second insertion opening. That is, the first path regulating member and the second path regulating member can be easily attached to the electric wire member from the outside. Therefore, for example, there is no need to use a welding device or the like, and complicated work such as passing the electric wire member through a pipe is also unnecessary, improving manufacturability.
[0011] [2] It is preferable that the second path regulating member is thicker than the first path regulating member, and that when attached to the vehicle, the second insertion opening is configured to open in the direction opposite to the direction of gravity.
[0012] According to this configuration, since the second path-regulating member, which is thicker than the first path-regulating member, is arranged in the direction of gravity, for example, when the wire harness is arranged to pass under the floor of a vehicle, the electric wire members are less likely to be damaged by flying stones from the ground. Also, since the first path-regulating member is thinner than the second path-regulating member, for example, it is easier to reduce the weight of the wire harness. Therefore, for example, it is possible to achieve weight reduction while maintaining the protective function of the electric wire members.
[0013] [3] The first path regulating member is preferably made of resin. According to this configuration, the first path regulating member is made of resin, which makes it lighter than a metal member, for example. Furthermore, the first path regulating member can be manufactured by extrusion molding, which improves manufacturability.
[0014] [4] The second path-regulating member is preferably made of resin. According to this configuration, the second path regulating member is made of resin, which allows for a lighter weight than, for example, a metal member. Furthermore, the second path regulating member can be manufactured by extrusion molding, which improves manufacturability.
[0015] [5] Preferably, the second path regulating member has protruding portions that protrude from both circumferential ends of the second main body portion and come into contact with the first path regulating member. According to this configuration, the second path regulating member has protrusions that protrude from both circumferential ends of the second main body portion and contact the first path regulating member, thereby strongly preventing the second path regulating member from detaching from the first path regulating member through the second insertion opening.
[0016] [6] It is preferable that the second main body portion has a surface contact portion at a position spaced from the protrusion portion, which covers a portion of the outer periphery of the first main body portion and makes surface contact with a portion of the outer periphery of the first main body portion. According to this configuration, the cross-sectional area of the wire harness can be made smaller than in a configuration in which, for example, protrusions are provided at locations other than both circumferential ends of the second main body portion and only point or line contact is made with the first main body portion, which is advantageous in reducing the wiring space for the wire harness.
[0017] [7] It is preferable that the wire member has a flat cross section, and the first insertion opening and the second insertion opening are open in the short direction of the cross section of the wire member. According to this configuration, for example, it is possible to reduce the dimension of the wire harness along the short direction of the cross section of the electric wire member. That is, it is possible to make the wire harness thinner. Therefore, it is advantageous for reducing the wiring space of the wire harness.
[0018] [8] It is preferable that the electric wire member has an electric wire and a braided member covering the outer periphery of the electric wire, and that the first path-control member directly contacts the braided member to prevent movement of the electric wire member inside the first path-control member.
[0019] According to this configuration, the electric wire member is prevented from moving inside the first path restricting member, which makes it possible to prevent the electric wire member from being damaged due to movement, for example.
[0020] [Details of the embodiments 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 configuration may be exaggerated or simplified. Furthermore, the dimensional ratios of each part may differ from one drawing to another. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In this specification, "orthogonal" does not only refer to a strict orthogonal case, but also includes a roughly orthogonal case within the scope of the effects of the present embodiment. Furthermore, in this specification, "circle" and "arc" do not only refer to a strict circle or arc, but also include a roughly circle or arc within the scope of the effects of the present embodiment.
[0021] (Overall configuration of the wire harness 10) 1 electrically connects two or more electrical devices. The wire harness 10 electrically connects an inverter 11 installed in the front of a vehicle V, such as a hybrid vehicle or an electric vehicle, to a high-voltage battery 12 installed behind the inverter 11 on the vehicle V. The wire harness 10 is routed, for example, so as to pass under the floor of the vehicle V. For example, a middle portion of the wire harness 10 in the longitudinal direction is routed so as to pass outside the passenger compartment of the vehicle V, such as under the floor of the vehicle V.
[0022] The inverter 11 is connected to a wheel drive motor (not shown) that serves as a power source for running the vehicle. The inverter 11 generates AC power from DC power from a high-voltage battery 12 and supplies the AC power to the motor. The high-voltage battery 12 is a battery capable of supplying a voltage of, for example, several hundred volts.
[0023] 2 and 3 , the wire harness 10 includes an electric wire member 20 that electrically connects the above-mentioned electric devices to each other. The wire harness 10 also includes a first path regulating member 30 attached to the outer periphery of the electric wire member 20 and a second path regulating member 40 attached to the outer periphery of the first path regulating member 30. The first path regulating member 30 and the second path regulating member 40 protect the electric wire member 20 and regulate the path along which the electric wire member 20 is routed, for example, under the floor of the vehicle V. The first path regulating member 30 and the second path regulating member 40 act to make the electric wire member 20 less likely to bend than the electric wire member 20 in a state where the first path regulating member 30 and the second path regulating member 40 are not attached, thereby suppressing deviation of the electric wire member 20 from the path.
[0024] (Configuration of the electric wire member 20) The electric wire member 20 has one or more electric wires 21 and a braided member 24 that collectively covers the outer periphery of the electric wires 21. The electric wire member 20 of this embodiment has two electric wires 21. One end of the electric wire member 20 is connected to the inverter 11 via a connector C1, and the other end of the electric wire member 20 is connected to the high-voltage battery 12 via a connector C2. The electric wire member 20 is formed in an elongated shape so as to extend in the fore-and-aft direction of the vehicle V, for example. The electric wire 21 is, for example, a high-tension electric wire that can handle high voltages and large currents. Note that the electric wire 21 may be, for example, a non-shielded electric wire that does not have an electromagnetic shielding structure itself, or a shielded electric wire that has an electromagnetic shielding structure itself.
[0025] (Configuration of electric wire 21) Each of the electric wires 21 is a coated electric wire having a core wire 22 made of a conductor and an insulating coating 23 that coats the outer periphery of the core wire 22 .
[0026] (Configuration of core wire 22) The core wire 22 can be, for example, a stranded wire made by twisting together multiple metal wires, a columnar conductor made of a single columnar metal rod with a solid interior, or a tubular conductor with a hollow interior. The core wire 22 can also be a combination of multiple types of conductors, such as a stranded wire, a columnar conductor, and a tubular conductor. Examples of columnar conductors include a single core wire and a bus bar. The core wire 22 of this embodiment is a stranded wire. The core wire 22 can be made of, for example, a copper-based or aluminum-based metal material.
[0027] The cross-sectional shape of the core wire 22 cut along a plane perpendicular to the length direction of the core wire 22, i.e., the length direction of the electric wire 21 (hereinafter referred to as the cross-sectional shape) can be any shape. The cross-sectional shape of the core wire 22 is formed into, for example, a circular shape, a semicircular shape, a polygonal shape, a square shape, a flat shape, etc. The cross-sectional shape of the core wire 22 in this embodiment is formed into a circular shape.
[0028] (Configuration of insulating coating 23) The insulating coating 23, for example, covers the entire outer periphery of the core wire 22. The insulating coating 23 is made of an insulating material such as a synthetic resin. For example, the material of the insulating coating 23 may be a synthetic resin containing a polyolefin resin, such as cross-linked polyethylene or cross-linked polypropylene, as a main component. Furthermore, the material of the insulating coating 23 may be one type of material alone, or two or more types of materials may be used in appropriate combination.
[0029] (Configuration of braided member 24) The braided member 24 has, for example, a cylindrical shape that collectively covers the outer peripheries of the plurality of electric wires 21. For example, the braided member 24 is provided so as to cover the outer peripheries of the electric wires 21 over substantially the entire length of the electric wires 21. The braided member 24 may be a braided wire formed by weaving a plurality of metal wires or a braided wire formed by combining metal wires and resin wires. The metal wires may be made of, for example, a copper-based or aluminum-based metal material. Although not shown in the drawings, the braided member 24 is connected to earth at, for example, each of the connectors C1, C2.
[0030] The electric wire member 20, which includes two electric wires 21 and a braided member 24 that covers them collectively, has a flat cross-sectional shape. Specifically, the cross-sectional shape of the electric wire member 20 is a flat shape having a longitudinal direction (left-right direction in FIG. 2 ) along the direction in which the electric wires 21 are lined up, and a lateral direction (up-down direction in FIG. 2 ) that is perpendicular to the longitudinal direction and along the direction in which the electric wires 21 are not lined up.
[0031] (Configuration of the first path regulating member 30) 2 and 3 , the first path restriction member 30 is attached to the electric wire member 20 while covering a part of the outer periphery of the electric wire member 20. The first path restriction member 30 extends along the longitudinal direction of the electric wire member 20. The first path restriction member 30 of the present embodiment is attached to the outer periphery of a portion of the routing path of the electric wire member 20, such as under the floor of the vehicle V, where the electric wire member 20 extends linearly.
[0032] The first path regulating member 30 is made of resin. Examples of materials that can be used for the first path regulating member 30 include synthetic resins such as polypropylene, polyamide, and polyacetal. The first path regulating member 30 can be manufactured by well-known manufacturing methods, such as extrusion molding and injection molding. The first path regulating member 30 of this embodiment has a uniform cross-sectional shape. The first path regulating member 30 of this embodiment is an extrusion-molded product manufactured by extrusion molding. Therefore, the first path regulating member 30 can be easily manufactured by using an extruder that extrudes the raw material of the first path regulating member 30 in the longitudinal direction. Furthermore, a single extruder can be used to manufacture multiple types of first path regulating members 30 with different longitudinal dimensions. For example, multiple types of first path regulating members 30 with different longitudinal dimensions can be manufactured by cutting the base material of the first path regulating member 30 formed by a single extruder to any desired length using a cutting machine.
[0033] The first path restricting member 30 has a first main body portion 31 and a first insertion opening 32. The first main body portion 31 is formed to cover a portion of the outer periphery of the electric wire member 20. The first main body portion 31 is formed to cover a range of the outer periphery of the electric wire member 20 that is greater than half of the entire circumferential circumference of the electric wire member 20. The first insertion opening 32 is formed by both circumferential end portions 33 of the first main body portion 31, opens in a direction perpendicular to the longitudinal direction of the first path restricting member 30, extends over the entire longitudinal direction, and is configured to allow the electric wire member 20 to be inserted therein. The first insertion opening 32 opens in the short direction of the cross-sectional shape of the electric wire member 20. The first main body portion 31 of the present embodiment has a flat first flat portion 34 that covers upper portions of two electric wires 21 that are arranged horizontally when the wire harness 10 is attached to the vehicle V, and arc-shaped first arc portions 35 that extend from both ends of the first flat portion 34 and cover side portions of the electric wires 21. The tip ends of the first arcuate portion 35 are circumferentially opposite ends 33 of the first main body portion 31, forming the first insertion opening 32. The first path regulating member 30 is configured so that the inner surface of the first main body portion 31 comes into direct contact with the braided member 24, thereby preventing movement of the wire member 20 inside the first path regulating member 30.
[0034] The opening width of the first insertion opening 32, that is, the shortest distance between both circumferential ends 33 of the first main body portion 31, is smaller than the width of the wire member 20 in the longitudinal direction (left-right direction in FIG. 2) in its cross-sectional shape.
[0035] When the electric wire member 20 is inserted into the first insertion opening 32 in a direction perpendicular to the longitudinal direction, the first path regulating member 30 is elastically deformed, and the opening width of the first insertion opening 32 is increased. When the electric wire member 20 is inserted into the first path regulating member 30, the first path regulating member 30 elastically returns to its original shape. As a result, the opening width of the first insertion opening 32 decreases, and the electric wire member 20 is accommodated in the first path regulating member 30, and the first path regulating member 30 is attached to the electric wire member 20.
[0036] (Configuration of the second path regulating member 40) 2 and 3 , the second path-regulating member 40 is attached to the first path-regulating member 30 while covering a portion of the outer periphery of the first path-regulating member 30. The second path-regulating member 40 extends along the longitudinal direction of the electric wire member 20. The second path-regulating member 40 of the present embodiment is attached to the same position as the first path-regulating member 30, for example, to the outer periphery of a portion of the routing path of the electric wire member 20, such as under the floor of the vehicle V, where the electric wire member 20 extends linearly.
[0037] The second path regulating member 40 is made of resin. Examples of materials that can be used for the second path regulating member 40 include synthetic resins such as polypropylene, polyamide, and polyacetal. The second path regulating member 40 can be manufactured by well-known manufacturing methods, such as extrusion molding and injection molding. The second path regulating member 40 of this embodiment has a uniform cross-sectional shape. The second path regulating member 40 of this embodiment is an extrusion-molded product manufactured by extrusion molding. Therefore, the second path regulating member 40 can be easily manufactured by using an extruder that extrudes the raw material of the second path regulating member 40 in the longitudinal direction. Furthermore, a single extruder can be used to manufacture multiple types of second path regulating members 40 with different longitudinal dimensions. For example, multiple types of second path regulating members 40 with different longitudinal dimensions can be manufactured by cutting the base material of the second path regulating member 40 formed by a single extruder to any desired length using a cutting machine.
[0038] The second path restricting member 40 has a second main body portion 41 and a second insertion opening 42. The second main body portion 41 covers a portion of the outer periphery of the first main body portion 31 and closes the first insertion opening 32. The second insertion opening 42 is formed by both circumferential end portions 43 of the second main body portion 41, opens in a direction perpendicular to the longitudinal direction of the second path restricting member 40, extends over the entire longitudinal direction, and is configured to allow the first path restricting member 30 to be inserted therein. The second insertion opening 42 opens in the short direction of the cross-sectional shape of the electric wire member 20. The second main body portion 41 of the present embodiment has a flat second flat portion 44 that covers lower portions of two electric wires 21 arranged horizontally when the wire harness 10 is attached to the vehicle V, and arc-shaped second arc portions 45 that extend from both ends of the second flat portion 44 and cover side portions of the electric wires 21. The tip ends of the second arcuate portion 45 are circumferentially opposite end portions 43 of the second main body portion 41, forming the second insertion opening 42. As a result, the second insertion opening 42 is set to open in the opposite direction to the direction of gravity when the wire harness 10 is attached to the vehicle V. The second path restricting member 40 is formed thicker than the first path restricting member 30. In other words, the second main body portion 41 is formed thicker than the first main body portion 31.
[0039] The second path regulating member 40 also has protrusions 46. The protrusions 46 protrude from both circumferential end portions 43 of the second main body portion 41 and come into contact with the first path regulating member 30. The cross-sectional shape of the protrusions 46 is formed, for example, in a curved shape. In this embodiment, the cross-sectional shape of the protrusions 46 is formed in an arc shape. The protrusions 46 extend in the length direction of the second path regulating member 40. The protrusions 46 extend, for example, over the entire length of the second path regulating member 40 in the length direction.
[0040] The protrusion 46 presses the first path regulating member 30 from the outside. In this embodiment, the protrusion 46 comes into contact with the first arc portion 35 of the first main body portion 31 and presses the first arc portion 35 from the outside. The second path regulating member 40 is attached to the first path regulating member 30 by elastically sandwiching the first path regulating member 30 between the second main body portion 41 and the protrusion 46.
[0041] Furthermore, the second main body portion 41 has, at a portion spaced apart from the protruding portion 46, a surface contact portion 47 that covers part of the outer periphery of the first main body portion 31 and comes into surface contact with part of the outer periphery of the first main body portion 31. In other words, the second main body portion 41 does not have any protruding portions at portions other than both end portions 43 in the circumferential direction of the second main body portion 41, and the second arc portion 45 at a portion spaced apart from the protruding portion 46 is the surface contact portion 47 that comes into surface contact with the first arc portion 35.
[0042] The opening width of the second insertion opening 42, that is, the shortest distance between both circumferential ends 43 of the second main body portion 41, is smaller than the width of the first main body portion 31 in the longitudinal direction (left-right direction in FIG. 2) in its cross-sectional shape.
[0043] When the first path regulating member 30 attached to the electric wire member 20 is inserted into the second insertion opening 42 from a direction perpendicular to the longitudinal direction, the second path regulating member 40 is elastically deformed, and the opening width of the second insertion opening 42 is increased. When the first path regulating member 30 is inserted into the second path regulating member 40, the second path regulating member 40 elastically returns to its original shape. As a result, the opening width of the second insertion opening 42 is reduced, and the first path regulating member 30 is accommodated in the second path regulating member 40, and the second path regulating member 40 is attached to the first path regulating member 30.
[0044] Next, the operation of this embodiment will be described. According to the wire harness 10 of the present embodiment, the first path-regulating member 30 can be later attached to the electric wire member 20 through the first insertion opening 32. In other words, the first path-regulating member 30 can be assembled to the electric wire member 20 from a direction perpendicular to the longitudinal direction of the electric wire member 20. Furthermore, the second path-regulating member 40 can be later attached to the first path-regulating member 30 through the second insertion opening 42. In other words, the second path-regulating member 40 can be assembled to the first path-regulating member 30 from a direction perpendicular to the longitudinal direction of the first path-regulating member 30. Therefore, for example, after the connectors C1, C2 are attached to both ends of the electric wire member 20, the first path-regulating member 30 and the second path-regulating member 40 can be later attached to the electric wire member 20.
[0045] Furthermore, at the portion where the first path regulating member 30 and the second path regulating member 40 are attached to the electric wire member 20, for example, foreign objects are prevented from colliding with the electric wire member 20, and bending of the wire harness 10 is suppressed even if vibration or some external force is applied.
[0046] The effects of this embodiment will be described. (1) A portion of the outer periphery of the electric wire member 20 is covered by the first main body portion 31 of the first path regulating member 30. Furthermore, a portion of the outer periphery of the electric wire member 20 that is not covered by the first main body portion 31 and corresponds to the first insertion opening 32 is covered by the second main body portion 41 of the second path regulating member 40. This covers and protects the entire outer periphery of the electric wire member 20, and regulates its path. The first path regulating member 30 can be attached to the electric wire member 20 through the first insertion opening 32. The second path regulating member 40 can be attached to the first path regulating member 30 through the second insertion opening 42. That is, the first path regulating member 30 and the second path regulating member 40 can be easily attached to the electric wire member 20 from the outside. Therefore, for example, there is no need to use a welding device or the like, and complicated work such as passing the electric wire member 20 through a pipe is also unnecessary, resulting in improved manufacturability.
[0047] (2) Since the second path-regulating member 40, which is thicker than the first path-regulating member 30, is disposed in the direction of gravity, for example, when the wire harness 10 is disposed to pass under the floor of the vehicle V, the wire members 20 are less likely to be damaged by flying stones from the ground. Furthermore, since the first path-regulating member 30 is thinner than the second path-regulating member 40, for example, it is easier to reduce the weight of the wire harness 10. Therefore, for example, it is possible to achieve weight reduction while maintaining the protective function of the wire members 20.
[0048] (3) Because the first path regulating member 30 is made of resin, it can be made lighter than, for example, a metal member. In addition, the first path regulating member 30 can be manufactured by extrusion molding, which improves manufacturability.
[0049] (4) Because the second path regulating member 40 is made of resin, it can be made lighter than, for example, a metal member. In addition, the second path regulating member 40 can be manufactured by extrusion molding, which improves manufacturability.
[0050] (5) The second path regulating member 40 has protrusions 46 that protrude from both circumferential ends 43 of the second main body portion 41 and contact the first path regulating member 30, thereby strongly preventing the second path regulating member 40 from detaching from the first path regulating member 30 through the second insertion opening 42.
[0051] (6) The second main body portion 41 has, at a position separated from the protruding portion 46, a surface contact portion 47 that covers a part of the outer periphery of the first main body portion 31 and is in surface contact with a part of the outer periphery of the first main body portion 31. Therefore, the cross-sectional area of the wire harness 10 can be made smaller than in a configuration in which, for example, protruding portions are provided at positions other than both circumferential end portions 43 of the second main body portion 41 and only make point contact or line contact with the first main body portion 31. This is advantageous in reducing the routing space of the wire harness 10.
[0052] (7) The wire member 20 has a flat cross-sectional shape, and the first insertion opening 32 and the second insertion opening 42 are open in the short direction of the cross-sectional shape of the wire member 20. Therefore, for example, it is possible to reduce the dimension of the wire harness 10 along the short direction of the cross-sectional shape of the wire member 20. That is, it is possible to make the wire harness 10 thinner. This is advantageous in reducing the routing space of the wire harness 10.
[0053] (8) The electric wire member 20 includes an electric wire 21 and a braided member 24 that covers the outer periphery of the electric wire 21, and the first path restricting member 30 is configured to be in direct contact with the braided member 24 to prevent movement of the electric wire member 20 inside the first path restricting member 30. Therefore, the electric wire member 20, more specifically, the electric wire 21 and the braided member 24, are prevented from moving inside the first path restricting member 30. Therefore, for example, it is possible to prevent the electric wire member 20 from being damaged due to movement of the electric wire member 20.
[0054] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

If the second path-restricting member 40 is made of metal in this way, it is possible to suppress an increase in the temperature of the electric wire member 20, for example, when the electric wire member 20 is disposed in a position close to a heat source of the vehicle V.
[0059] In the above embodiment, the second path regulating member 40 has the protruding portions 46 that protrude from both circumferential end portions 43 of the second main body portion 41 and come into contact with the first path regulating member 30. However, this is not limited thereto, and the second path regulating member 40 may be configured without the protruding portions 46. Furthermore, the second path regulating member 40 may be configured to have protruding portions that protrude from portions of the second main body portion 41 other than both circumferential end portions 43 and come into contact with the first path regulating member 30. Furthermore, the protruding portions 46 may be provided partially in the length direction of the second path regulating member 40.
[0060] In the above embodiment, the second main body portion 41 has a surface contact portion 47 that makes surface contact with a portion of the outer periphery of the first main body portion 31, but this is not limited to this, and the second main body portion 41 may be configured not to have a surface contact portion 47.
[0061] In the above embodiment, the electric wire member 20 has a flat cross-sectional shape, but this is not limited thereto, and the electric wire member 20 may have another cross-sectional shape, such as a circular shape. In this case, the number of electric wires 21 included in the electric wire member 20 may be changed to one or three or more. In this case, it is also preferable to change the shapes of the first path regulating member 30 and the second path regulating member 40 according to the shape of the electric wire member.
[0062] In the above embodiment, the first insertion opening 32 and the second insertion opening 42 are open in the short direction of the cross-sectional shape of the wire member 20, but this is not limited thereto, and for example, they may be configured to open in the longitudinal direction of the cross-sectional shape of the wire member 20.
[0063] In the above embodiment, the electric wire member 20 has the braided member 24, but this is not limitative and the electric wire member 20 may not have the braided member 24. In the above embodiment, the electric wire member 20 is configured to have the braided member 24 on the outermost side, but this is not limitative. For example, the electric wire member 20 may be configured to have another exterior member on the outermost side.
[0064] In the above embodiment, the first path-controlling member 30 is in direct contact with the braided member 24 to prevent movement of the wire member 20 inside the first path-controlling member 30, but this is not limited to this, and the first path-controlling member 30 may be configured not to be in direct contact with the braided member 24.
[0065] The first path regulating member 30 and the second path regulating member 40 in the above embodiment are not limited to being provided under the floor of the vehicle V. The first path regulating member 30 and the second path regulating member 40 may be provided, for example, inside the passenger compartment of the vehicle V, as long as they are a linearly extending portion of the routing path of the electric wire member 20.
