Description

[Technical Field]

[0001] The present disclosure relates to a wiring member and a wire harness. [Background technology]

[0002] Conventionally, some wire harnesses used in vehicles such as hybrid cars and electric cars electrically connect electrical devices that receive power from a high-voltage battery (see, for example, Patent Document 1). The wire harness includes at least one electric wire that electrically connects the electrical devices. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-171952 Summary of the Invention [Problem to be solved by the invention]

[0004] Meanwhile, vehicles such as hybrid cars and electric cars are equipped with a low-voltage battery that can supply a voltage lower than that of the high-voltage battery, in addition to the high-voltage battery. Generally, a high-voltage battery is often located toward the rear of a vehicle. The electrical devices that receive power from the high-voltage battery are divided into those located toward the rear of the vehicle and those located toward the front of the vehicle. The electrical devices located toward the rear of the vehicle and those located toward the front of the vehicle are electrically connected by electric wires routed, for example, under the floor of the vehicle.

[0005] Generally, the power of the low-voltage battery is supplied to electrical devices via an electrical connection box such as a fuse box, a junction box, a relay box, etc. The electrical connection box is often located near the front of the vehicle, while the low-voltage battery is sometimes located near the rear of the vehicle, and sometimes located near the front of the vehicle.

[0006] When the low-voltage battery is located toward the rear of the vehicle, the electric wires electrically connecting the low-voltage battery and the electrical junction box are sometimes routed through the vehicle interior. However, routing the electric wires through the vehicle interior can be problematic due to issues such as electromagnetic noise and limited routing space. Therefore, it is desirable to route the electric wires electrically connecting the low-voltage battery and the electrical junction box through the underfloor of the vehicle, alongside the electric wires electrically connecting electrical devices that receive power from the high-voltage battery.

[0007] An object of the present disclosure is to provide a wiring member and a wire harness that can easily route electric wires used to supply power from a low-voltage battery along electric wires used to supply power from a high-voltage battery. [Means for solving the problem]

[0008] The routing member of the present disclosure comprises a first accommodating member having a first tubular member through which a first electric wire passes, and a second accommodating member having a second tubular member different from the first tubular member through which a second electric wire different from the first electric wire passes, wherein the first accommodating member has at least one first connecting portion integrally formed with the first tubular member, and the second accommodating member has at least one second connecting portion integrally formed with the second tubular member, and the second connecting portion is connected to the first connecting portion to maintain a state in which the second tubular member is arranged along the first tubular member together with the first connecting portion.

[0009] The wire harness of the present disclosure is a wire harness including the above-mentioned routing member, at least one first electric wire passing through the first tubular member, and at least one second electric wire passing through the second tubular member. [Effects of the Invention]

[0010] According to the wiring member and wire harness of the present disclosure, the wires used to supply power from the low-voltage battery can be easily routed along the wires used to supply power from the high-voltage battery. [Brief explanation of the drawings]

[0012] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The wiring member of the present disclosure includes: [1] A wiring member comprising: a first accommodating member having a first tubular member through which a first electric wire passes; and a second accommodating member having a second tubular member different from the first tubular member through which a second electric wire different from the first electric wire passes, wherein the first accommodating member has at least one first connecting portion integrally formed with the first tubular member, and the second accommodating member has at least one second connecting portion integrally formed with the second tubular member, and the second connecting portion is connected to the first connecting portion to maintain a state in which the second tubular member is arranged along the first tubular member together with the first connecting portion.

[0013] According to this configuration, by connecting the first connecting portion and the second connecting portion, the second tubular member can be easily arranged along the first tubular member. Therefore, the second electric wire passing through the second tubular member can be easily routed along the first electric wire passing through the first tubular member. For example, the electric wire used to supply power from the low-voltage battery (e.g., the second electric wire) can be easily routed along the electric wire used to supply power from the high-voltage battery (e.g., the first electric wire).

[0014] In addition, when it is not necessary to route the second electric wire along the first electric wire, it is possible to use only the first accommodating member out of the first and second accommodating members by not connecting the second connecting portion to the first connecting portion. In other words, it is possible to choose whether or not to use the second accommodating member. Therefore, it is possible to use different routing members depending on whether the second electric wire is routed along the first electric wire or whether only the required electric wire (for example, the first electric wire) is routed.

[0015] [2] Preferably, each of the first tubular member and the second tubular member has enough rigidity to maintain its own shape. This configuration facilitates handling of the first and second accommodating members. Consequently, handling of the wiring member is also facilitated. Furthermore, the strength of each of the first and second tubular members can be increased compared to when the first and second tubular members do not have the rigidity required to maintain their shape. Therefore, the first and second tubular members can more easily protect the first and second electric wires from foreign objects that come into contact with the wire harness including the wiring member.

[0016] [3] It is preferable that the first tubular member has a rectangular cross-section whose height is lower than its width, and the second tubular member has a rectangular cross-section whose height is lower than its width or whose width and height are equal, and that the first tubular member and the second tubular member are aligned in the width direction of the first tubular member and arranged so that the height direction of the first tubular member is parallel to the height direction of the second tubular member.

[0017] According to this configuration, it is possible to prevent the routing member from becoming large in the height direction of the first tubular member. [4] It is preferable that the second tubular member be within the height range of the first tubular member along the height direction of the first tubular member.

[0018] According to this configuration, the routing member can be made thinner in the height direction of the first tubular member compared to when the second tubular member has a portion that is positioned outside the height range of the first tubular member.

[0019] [5] It is preferable that the internal space of the first tubular member has a width that allows a plurality of the first electric wires to be arranged side by side along the width direction of the first tubular member. According to this configuration, when there are multiple first electric wires passing through the first tubular member, the height of the first tubular member can be prevented from increasing compared to when the multiple first electric wires are arranged so as to overlap in the height direction of the first tubular member, which contributes to making the wiring member thinner in the height direction of the first tubular member.

[0020] [6] It is preferable that each of the first connecting portion and the second connecting portion is within the height range of the first tubular member and within the height range of the second tubular member along the height direction of the first tubular member.

[0021] According to this configuration, it is possible to prevent the routing member from becoming large in size in the height direction of the first tubular member. [7] It is preferable that the first tubular member has a first side wall at one end of the first tubular member in the width direction of the first tubular member, the second tubular member has a second side wall opposite the first side wall, and each of the first connecting portion and the second connecting portion is located between the first side wall and the second side wall in the width direction of the first tubular member.

[0022] This configuration can prevent at least one of the first connecting portion and the second connecting portion from having a complicated shape and can prevent at least one of the first connecting portion and the second connecting portion from becoming large.

[0023] [8] It is preferable that the first tubular member has a first side wall at one end of the first tubular member in the width direction of the first tubular member, the second tubular member has a second side wall opposite to the first side wall, and the connection between the first connecting portion and the second connecting portion is located at the middle of the first side wall in the height direction of the first tubular member and at the middle of the second side wall in the height direction of the second tubular member.

[0024] This configuration can prevent the first tubular member and the second tubular member from rotating relative to each other around the connector, thereby preventing vibration of at least one of the first tubular member and the second tubular member.

[0025] [9] It is preferable that the first connecting portion protrudes from the first side wall toward the second side wall, the second connecting portion protrudes from the second side wall toward the first side wall, and the first connecting portion and the second connecting portion are overlapped in the height direction of the first tubular member.

[0026] According to this configuration, when connecting the first connecting portion and the second connecting portion, it is sufficient to connect the first connecting portion and the second connecting portion that are overlapped in the height direction of the first tubular member, so that the first connecting portion and the second connecting portion can be easily connected.

[0027]

[10] It is preferable that the first connecting portion has a first bolt hole penetrating in the height direction of the first tubular member, the second connecting portion has a second bolt hole penetrating in the height direction of the second tubular member, and the first bolt hole and the second bolt hole of the second connecting portion that is superimposed on the first connecting portion having the first bolt hole are aligned in the height direction of the first tubular member.

[0028] According to this configuration, the first connecting portion and the second connecting portion can be more easily connected by using the bolts that are passed through the first bolt holes and the second bolt holes and the nuts that are fitted onto the bolts.

[11] It is preferable that the first tubular member has a first side wall at one end of the first tubular member in the width direction of the first tubular member, and the second tubular member has a second side wall facing the first side wall and in face contact with the first side wall.

[0029] According to this configuration, when the first electric wire passing through the first tubular member generates heat due to the passage of current, the heat of the first electric wire is transferred to the first tubular member and then from the first side wall to the second tubular member. Therefore, the heat of the first electric wire can be dissipated from the second tubular member as well, thereby improving the heat dissipation performance of the wiring member.

[0030]

[12] It is preferable that the first tubular member has a first connecting side wall at one end of the first tubular member in the height direction of the first tubular member, and the second tubular member has a second connecting side wall at one end of the second tubular member in the height direction of the second tubular member, the first connecting portion is integrally formed with the first connecting side wall, the second connecting portion is integrally formed with the second connecting side wall, and the first connecting portion and the second connecting portion are overlapped in the width direction of the first tubular member or the length direction of the first tubular member.

[0031] According to this configuration, when connecting the first connecting part and the second connecting part, it is sufficient to connect the first connecting part and the second connecting part that are overlapped in the width direction or the length direction of the first tubular member, so that the first connecting part and the second connecting part can be easily connected.

[0032]

[13] It is preferable that the first connecting portion has a first bolt hole passing through the first connecting portion in the direction in which the first connecting portion and the second connecting portion overlap, and the second connecting portion has a second bolt hole passing through the second connecting portion in the direction in which the first connecting portion and the second connecting portion overlap, and that the first bolt hole and the second bolt hole of the second connecting portion that is overlapped on the first connecting portion having the first bolt hole are aligned in the direction in which the first connecting portion and the second connecting portion overlap.

[0033] According to this configuration, the first connecting portion and the second connecting portion can be more easily connected by using the bolts that are passed through the first bolt holes and the second bolt holes and the nuts that are fitted onto the bolts. The wire harness of the present disclosure includes:

[14] A wire harness comprising the above-mentioned routing member, at least one first electric wire passing through the first tubular member, and at least one second electric wire passing through the second tubular member.

[0034] This configuration can achieve the same effects as the above-mentioned wiring member. [Details of the embodiments of the present disclosure] Specific examples of the wiring member and wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, some components may be exaggerated or simplified. In this specification, "parallel" does not only mean strictly perpendicular, but also includes roughly parallel within the scope of the present embodiment's effects. In this specification, "orthogonal" does not only mean strictly perpendicular, but also includes roughly perpendicular within the scope of the present embodiment's effects. In this specification, "vertical" does not only mean strictly perpendicular, but also includes roughly perpendicular within the scope of the present embodiment's effects. In the drawings, the dimensional ratios of components may differ from the actual ones or from those in other drawings. The present invention is not limited to these examples, but is defined by the claims, and all modifications within the meaning and scope of the claims are intended to be included.

[0035] First Embodiment Hereinafter, a first embodiment of the wiring member and the wire harness will be described. (Configuration of wire harness 10) 1, a wire harness 10 is mounted on a vehicle V, such as a hybrid vehicle or an electric vehicle. The wire harness 10 electrically connects two or more electrical devices M1, M2, M3, and M4. The wire harness 10 is routed such that, for example, a portion of its length passes under the floor of the vehicle V.

[0036] 2, the wire harness 10 includes at least one first electric wire 20, at least one second electric wire 30 different from the first electric wire 20, and a routing member 40. The wire harness 10 includes, for example, two first electric wires 20, a first electric wire 20a and a first electric wire 20b. The wire harness 10 also includes, for example, one second electric wire 30.

[0037] (Configuration of the first electric wire 20) 3, each of the first electric wire 20a and the first electric wire 20b has an electrically conductive core wire 21 and an insulating coating 22 that covers the outer periphery of the core wire 21. Note that FIG. 3 is a cross-sectional view taken along line 3-3 in FIG. 2.

[0038] The core wire 21 may be, for example, a stranded wire made by twisting together a plurality of metal wires, a columnar conductor made of a single metal rod with a solid interior, or a tubular conductor with a hollow interior. Alternatively, the core wire 21 may be a combination of at least two of the stranded wire, columnar conductor, and tubular conductor. The core wire 21 may be made of, for example, a copper-based or aluminum-based metal material.

[0039] In each of the first electric wires 20a, 20b, the insulating coating 22 is, for example, cylindrical and covers the entire outer periphery of the core wire 21. The insulating coating 22 is made of, for example, a resin material having insulating properties.

[0040] The cross-sectional shape of each of the first electric wires 20a, 20b is, for example, a flat rectangular shape with a height shorter than its width. For example, the cross-sectional shape of the first electric wire 20a and the cross-sectional shape of the first electric wire 20b are the same shape and size. Note that the cross-sectional shape of each of the first electric wires 20a, 20b may be any of a rectangular shape other than a rectangular shape with a height shorter than its width, a polygonal shape other than a rectangular shape, a circle, an ellipse, a rounded rectangle, and any other shape.

[0041] The first electric wire 20a and the first electric wire 20b may be the same type of electric wire or different types of electric wire. For example, the first electric wire 20a and the first electric wire 20b are the same type of electric wire. Each of the first electric wires 20a, 20b may be, for example, a shielded electric wire that has an electromagnetic shielding structure itself, or a non-shielded electric wire that does not have an electromagnetic shielding structure itself. For example, each of the first electric wires 20a, 20b is a non-shielded electric wire.

[0042] As shown in FIG. 1 , one end of each of the first electric wires 20a, 20b is connected to an electric device M1, and the other end of each of the first electric wires 20a, 20b is connected to an electric device M2. The electric device M1 is, for example, an inverter provided toward the rear of the vehicle V. The electric device M1 is arranged, for example, near a trunk room of the vehicle V. The electric device M2 is, for example, a motor provided forward of the vehicle V relative to the electric device M1. This motor is a wheel drive motor that provides power for traveling the vehicle. The electric device M2 is, for example, arranged in an engine room of the vehicle V. Note that, for example, an electric device M5 is arranged near the rear of the vehicle V, for example, in a position near the electric device M1. The electric device M5 is arranged, for example, near the trunk room of the vehicle V. The electric device M5 is, for example, a high-voltage battery capable of supplying a voltage of 100 volts or more. The electric device M1 is electrically connected to the electric device M5.

[0043] (Configuration of the second wire 30) As shown in FIG. 3, the second electric wire 30 has a conductive core wire 31 and an insulating coating 32 that covers the outer periphery of the core wire 21.

[0044] The core wire 31 may be, for example, a stranded wire made by twisting together multiple metal wires, a columnar conductor made of a single metal rod with a solid interior, or a hollow tubular conductor. Alternatively, the core wire 31 may be a combination of at least two of the stranded wire, columnar conductor, and tubular conductor. The core wire 31 may be made of, for example, a copper-based or aluminum-based metal material.

[0045] The insulating coating 32 is, for example, cylindrical and covers the entire outer periphery of the core wire 31. The insulating coating 32 is made of, for example, a resin material having insulating properties. The outer shape of the second electric wire 30 in cross section is, for example, a flat rectangular shape with a height shorter than its width. Note that the outer shape of the second electric wire 30 in cross section may be any of a rectangular shape other than a rectangular shape with a height shorter than its width, a polygonal shape other than a rectangular shape, a circle, an ellipse, a rounded rectangle, and any other shape. The second electric wire 30 is, for example, thinner than each of the first electric wires 20a, 20b. That is, the outer shape of the second electric wire 30 in cross section is, for example, smaller than each of the first electric wires 20a, 20b.

[0046] The second electric wire 30 may be, for example, a shielded electric wire that has an electromagnetic shielding structure itself, or a non-shielded electric wire that does not have an electromagnetic shielding structure itself. For example, the second electric wire 30 is a non-shielded electric wire.

[0047] As shown in FIG. 1 , one end of the second electric wire 30 is connected to an electric device M3, and the other end of the second electric wire 30 is connected to an electric device M4. The electric device M3 is, for example, a low-voltage battery provided toward the rear of the vehicle V. The low-voltage battery is a battery that can supply a lower voltage (for example, a voltage of 12 volts) than the high-voltage battery. The electric device M3 is, for example, disposed near the trunk of the vehicle V. The electric device M4 is, for example, an electric junction box provided further forward on the vehicle V than the electric device M3. Examples of the electric junction box include a relay box, a fuse box, and a junction box. The electric device M4 is, for example, disposed in the engine compartment of the vehicle V.

[0048] (Configuration of wiring member 40) As shown in FIGS. 2 and 3, the routing member 40 includes a first housing member 41 and a second housing member 51. As shown in FIG.

[0049] (Configuration of the first housing member 41) The first accommodating member 41 has a first tubular member 42 and at least one first connecting portion 43 that is provided integrally with the first tubular member 42 .

[0050] The first tubular member 42 has a tubular shape. The first tubular member 42 is configured, for example, by a metal pipe. The material of the first tubular member 42 can be, for example, aluminum or an aluminum alloy. Note that the material of the first tubular member 42 may be a metal material other than aluminum or an aluminum alloy. The first tubular member 42 has, for example, rigidity that allows it to maintain its own shape.

[0051] Here, a direction along the central axis X1 of the first tubular member 42 is defined as the length direction X11 of the first tubular member 42. Also shown in the figure are a first axis Y1 that is perpendicular to the central axis X1, and a second axis Z1 that is perpendicular to the central axis X1 and is also perpendicular to the first axis Y1. A direction along the first axis Y1 is defined as the width direction Y11 of the first tubular member 42. Furthermore, a direction along the second axis Z1 is defined as the height direction Z11 of the first tubular member 42. The width direction Y11 is a direction perpendicular to the length direction X11. The height direction Z11 is a direction perpendicular to the length direction X11 and also perpendicular to the width direction Y11.

[0052] The first tubular member 42 has, for example, a rectangular cross-section whose height is shorter than its width. Note that the term "rectangular shape" used in this description can refer to a rectangle with rounded corners as well as a rectangle with sharp corners. The cross-section of the first tubular member 42 is a cross section perpendicular to the central axis X1. The width of the first tubular member 42 is the length of the first tubular member 42 in the width direction Y11. The height of the first tubular member 42 is the length of the first tubular member 42 in the height direction Z11.

[0053] The first electric wire 20a and the first electric wire 20b pass through the first tubular member 42. A portion of the length of each of the first electric wires 20a and 20b is housed inside the first tubular member 42. The internal space S1 of the first tubular member 42 has a width that allows a plurality of first electric wires 20 to be arranged side by side along the width direction Y11. For example, the internal space S1 has a width W1 that allows the first electric wire 20a and the first electric wire 20b to be arranged side by side along the width direction Y11. The first electric wire 20a is arranged inside the first tubular member 42 so that the height direction of the first electric wire 20a is aligned with the height direction Z11 of the first tubular member 42. Similarly, the first electric wire 20b is arranged inside the first tubular member 42 so that the height direction of the first electric wire 20b is aligned with the height direction Z11 of the first tubular member 42. Therefore, each of the first electric wires 20a, 20b passing through the first tubular member 42 is thin in the height direction Z11 and wide in the width direction Y11 in the cross section of the wire harness 10.

[0054] The first tubular member 42 has, for example, four side walls 42a, 42b, 42c, and 42d. Of the four side walls 42a to 42d, two side walls 42a and 42b are located at both ends of the first tubular member 42 in the width direction Y11. The remaining two side walls 42c and 42d are located at both ends of the first tubular member 42 in the height direction Z11. The side wall 42c connects an end of the side wall 42a in the height direction Z11 to an end of the side wall 42b in the height direction Z11. The side wall 42d connects an end of the side wall 42a in the opposite direction to the height direction Z11 to an end of the side wall 42b in the opposite direction to the height direction Z11. The first tubular member 42 has the side wall 42a at one end of the first tubular member 42 in the width direction Y11. The side wall 42a corresponds to the "first side wall." Of the two side walls 42a, 42b at both ends of the first tubular member 42 in the width direction Y11, the side wall 42a is located closer to the rear in the width direction Y11 than the side wall 42b. The side wall 42a has, for example, a flat plate shape perpendicular to the width direction Y11.

[0055] The first accommodating member 41 has, for example, a plurality of first connecting portions 43 integrally provided on the side wall 42a. The first connecting portions 43 are provided, for example, on the first tubular member 42 at a plurality of locations at intervals of several tens of centimeters (for example, at intervals of 50 to 100 cm) along the longitudinal direction X11.

[0056] Each of the first connecting portions 43 protrudes, for example, from the side wall 42a along the first axis Y1 in the direction opposite to the width direction Y11. Each of the first connecting portions 43 has, for example, a flat plate shape perpendicular to the height direction Z11. Each of the first connecting portions 43 has, for example, a first mating surface 43a. The first mating surface 43a is, for example, one of both end surfaces of the first connecting portion 43 in the height direction Z11 that is located toward the rear in the height direction Z11. The first mating surface 43a is located midway between the side wall 42a in the height direction Z11. The first mating surface 43a has, for example, a flat shape perpendicular to the height direction Z11.

[0057] Each of the first connecting portions 43 may have a first bolt hole 44 penetrating therethrough in the height direction Z11. The first accommodating member 41 is arranged, for example, in a manner in which at least a portion of the first tubular member 42 in the longitudinal direction X11 passes under the floor of the vehicle V. Therefore, each of the first electric wires 20a and the first electric wires 20b passing through the first tubular member 42 is arranged, for example, in a manner in which a portion of the length direction passes under the floor of the vehicle V. Furthermore, the first tubular member 42 is attached to the vehicle V, for example, such that the height direction Z11 is aligned with the up-down direction of the vehicle V.

[0058] (Configuration of second accommodating member 51) The second accommodating member 51 has a second tubular member 52 that is different from the first tubular member 42 and at least one second connecting portion 53 that is provided integrally with the second tubular member 52 .

[0059] The second tubular member 52 has a tubular shape. The second tubular member 52 is made of, for example, a metal pipe. The material of the second tubular member 52 can be, for example, aluminum or an aluminum alloy. Note that the material of the second tubular member 52 may be a metal material other than aluminum or an aluminum alloy. The second tubular member 52 has, for example, rigidity that allows it to maintain its own shape.

[0060] Here, a direction along the central axis X2 of the second tubular member 52 is defined as the length direction X21 of the second tubular member 52. Also shown in the figure are a first axis Y2 that is perpendicular to the central axis X2, and a second axis Z2 that is perpendicular to the central axis X2 and perpendicular to the first axis Y2. A direction along the first axis Y2 is defined as the width direction Y21 of the second tubular member 52. Furthermore, a direction along the second axis Z2 is defined as the height direction Z21 of the second tubular member 52. The width direction Y21 is a direction perpendicular to the length direction X21. The height direction Z21 is a direction perpendicular to the length direction X21 and also perpendicular to the width direction Y21.

[0061] The second tubular member 52 has, for example, a rectangular cross-section whose height is shorter than its width or whose width and height are equal. The second tubular member 52 has, for example, a rectangular cross-section whose height is shorter than its width. The width of the second tubular member 52 is the length of the second tubular member 52 in the width direction Y21. The height of the second tubular member 52 is the length of the second tubular member 52 in the height direction Z21. The height of the second tubular member 52 is, for example, equal to the height of the first tubular member 42. The width of the second tubular member 52 is, for example, narrower than the width of the first tubular member 42.

[0062] The second electric wire 30 passes through the second tubular member 52. A longitudinal portion of the second electric wire 30 is housed inside the second tubular member 52. The second electric wire 30 is disposed inside the second tubular member 52 such that the height direction of the second electric wire 30 is aligned with the height direction Z21 of the second tubular member 52. Therefore, in the cross section of the wire harness 10, the second electric wire 30 passing through the second tubular member 52 is thin in the height direction Z21 and wide in the width direction Y21.

[0063] The second tubular member 52 has, for example, four side walls 52a, 52b, 52c, and 52d. Of the four side walls 52a to 52d, two side walls 52a and 52b are located at both ends of the second tubular member 52 in the width direction Y21. The remaining two side walls 52c and 52d are located at both ends of the second tubular member 52 in the height direction Z21. The side wall 52c connects an end of the side wall 52a in the height direction Z21 to an end of the side wall 52b in the height direction Z21. The side wall 52d connects an end of the side wall 52a in the opposite direction to the height direction Z21 to an end of the side wall 52b in the opposite direction to the height direction Z21. The side wall 52b corresponds to the "second side wall." Of the two side walls 52a, 52b at both ends of the second tubular member 52 in the width direction Y21, the side wall 52b is located closer to the front in the width direction Y21 than the side wall 52a. The side wall 52b has, for example, a flat plate shape perpendicular to the width direction Y21.

[0064] The second accommodating member 51 has, for example, a plurality of second connecting portions 53 that are integrally provided on the side wall 52b. The second accommodating member 51 has, for example, the same number of second connecting portions 53 as the first connecting portions 43. The second connecting portions 53 are provided, for example, at a plurality of locations on the second tubular member 52 at intervals of several tens of centimeters (for example, intervals of 50 to 100 cm) along the longitudinal direction X21.

[0065] Each of the second connecting portions 53 protrudes from the side wall 52b in the width direction Y21 along the first axis Y2, for example. Each of the second connecting portions 53 has a flat plate shape perpendicular to the height direction Z21, for example. Each of the second connecting portions 53 has a thickness equal to that of the first connecting portion 43, for example. Each of the second connecting portions 53 has a second mating surface 53a, for example. The second mating surface 53a is, for example, one of both end surfaces of the second connecting portion 53 in the height direction Z21 that is located closer to the front in the height direction Z21. The second mating surface 53a is located midway between the side wall 52b in the height direction Z21. The second mating surface 53a has a flat plate shape perpendicular to the height direction Z21, for example.

[0066] Each of the second connecting portions 53 may have a second bolt hole 54 penetrating therethrough in the height direction Z21. The second accommodating member 51 is connected to the first accommodating member 41 by connecting each second connecting portion 53 to each first connecting portion 43. Note that the connection between each first connecting portion 43 and each second connecting portion 53 may be performed before attaching the first accommodating member 41 to the vehicle V, or may be performed after attaching the first accommodating member 41 to the vehicle V.

[0067] The first tubular member 42 and the second tubular member 52 are arranged side by side in the width direction Y11 and such that the height direction Z11 of the first tubular member 42 and the height direction Z21 of the second tubular member 52 are parallel to each other. Furthermore, for example, the second accommodating member 51 is arranged such that the side wall 52b of the second tubular member 52 faces the side wall 42a of the first tubular member 42. That is, the second tubular member 52 may have a side wall 52b facing the side wall 42a. The side wall 42a and the side wall 52b face each other in the width direction Y11. Therefore, each first connecting portion 43 protrudes from the side wall 42a toward the side wall 52b. Furthermore, each second connecting portion 53 protrudes from the side wall 52b toward the side wall 42a.

[0068] Each first connecting portion 43 and each second connecting portion 53 are overlapped in the height direction Z11, for example. Each second connecting portion 53 is overlapped with each first connecting portion 43 with the second mating surface 53a abutting against the first mating surface 43a. The first bolt hole 44 and the second bolt hole 54 of the second connecting portion 53 overlapped with the first connecting portion 43 having the first bolt hole 44 are aligned in the height direction Z11. That is, in the overlapping first connecting portion 43 and second connecting portion 53, the first bolt hole 44 and the second bolt hole 54 are aligned in the overlapping direction with their penetration directions in the same direction. A bolt 61 is inserted into the first bolt hole 44 and the second bolt hole 54 aligned in the height direction Z11. The overlapping first connecting portion 43 and second connecting portion 53 are connected by a bolt 61 and a nut 62 fitted onto the bolt 61.

[0069] Each second connecting portion 53 is connected to each first connecting portion 43 and maintains the state in which the second tubular member 52 is arranged along the first tubular member 42 together with each first connecting portion 43. Each of the first connecting portion 43 and the second connecting portion 53 has sufficient rigidity to maintain the state in which the second tubular member 52 is arranged along the first tubular member 42.

[0070] By connecting each second coupling portion 53 to each first coupling portion 43, at least a portion of the second tubular member 52 in the longitudinal direction X21 is routed along the first tubular member 42. For example, the second tubular member 52 is routed along the first tubular member 42 that passes under the floor of the vehicle V, in a manner in which at least a portion of the second tubular member 52 in the longitudinal direction X21 passes under the floor of the vehicle V. The second electric wire 30 that penetrates the second tubular member 52 is routed such that at least a portion of the second electric wire 30 in its longitudinal direction is routed along the first electric wires 20a, 20b. For example, the second electric wire 30 is routed such that a portion of the second electric wire 30 in its longitudinal direction passes under the floor of the vehicle V. Furthermore, the first electric wire 20a, the first electric wire 20b, and the second electric wire 30 are arranged in a line, for example, along the width direction Y11.

[0071] When the second housing member 51 is connected to the first housing member 41, the second tubular member 52 is, for example, contained within the height range A1 of the first tubular member 42 along the height direction Z11. Therefore, the position in the height direction Z11 of the end face of the second tubular member 52 in the height direction Z21 is the same as the position in the height direction Z11 of the end face of the first tubular member 42 in the height direction Z11, or is located more rearward in the height direction Z11 than the end face of the first tubular member 42 in the height direction Z11. Furthermore, the position in the height direction Z11 of the end face of the second tubular member 52 on the opposite side to the height direction Z21 is the same as the position in the height direction Z11 of the end face of the first tubular member 42 on the opposite side to the height direction Z11, or is located more forward in the height direction Z11 than the end face of the first tubular member 42 on the opposite side to the height direction Z11.

[0072] In this state, for example, the first connecting portion 43 and the second connecting portion 53 each fall within a height range A1 of the first tubular member 42 and a height range A2 of the second tubular member 52 along the height direction Z11. In this state, for example, the first connecting portion 43 and the second connecting portion 53 each fall between the side wall 42a and the side wall 52b in the width direction Y11. In this state, for example, the connecting body 63 between the first connecting portion 43 and the second connecting portion 53 is located at the middle of the side wall 42a in the height direction Z11 and at the middle of the side wall 52b in the height direction Z21. In other words, the center of the connecting body 63 in the height direction Z11 and the center of the side wall 42a in the height direction Z11 may be located at the same position in the height direction Z11. The center of the connector 63 in the height direction Z21 and the center of the side wall 52b in the height direction Z21 may be located at the same position in the height direction Z21. The center of the connector 63 in the height direction Z11 or the height direction Z21 corresponds to, for example, the first mating surface 43a and the second mating surface 53a.

[0073] The effects of this embodiment will be described. (1-1) The routing member 40 includes a first accommodating member 41 having a first tubular member 42 through which the first electric wire 20 passes, and a second accommodating member 51 having a second tubular member 52 different from the first tubular member 42 through which a second electric wire 30 different from the first electric wire 20 passes. The first accommodating member 41 has at least one first coupling portion 43 provided integrally with the first tubular member 42. The second accommodating member 51 has at least one second coupling portion 53 provided integrally with the second tubular member 52. The second coupling portion 53 is coupled to the first coupling portion 43 and, together with the first coupling portion 43, maintains a state in which the second tubular member 52 is arranged along the first tubular member 42.

[0074] According to this configuration, by connecting the first connecting portion 43 and the second connecting portion 53, the second tubular member 52 can be easily arranged along the first tubular member 42. Therefore, the second electric wire 30 passing through the second tubular member 52 can be easily routed along the first electric wire 20 passing through the first tubular member 42. For example, the second electric wire 30 used to supply power from the low-voltage battery can be easily routed along the first electric wire 20 used to supply power from the high-voltage battery.

[0075] Note that, for example, when both the electric device M3 and the electric device M4 connected to the electric device M3 are arranged in a location closer to the front of the vehicle V, such as in the engine compartment, the second electric wire 30 does not need to be routed along the first electric wire 20. In this way, when the second electric wire 30 does not need to be routed along the first electric wire 20, it is possible to use only the first accommodating member 41 out of the first accommodating member 41 and the second accommodating member 51 by not connecting the second connecting portion 53 to the first connecting portion 43. In other words, it is possible to select whether or not to use the second accommodating member 51. Therefore, it is possible to use the routing member 40 in two cases: when the second electric wire 30 is routed along the first electric wire 20, and when, for example, only the first electric wire 20 is routed as a required electric wire.

[0076] (1-2) Each of the first tubular member 42 and the second tubular member 52 has rigidity sufficient to maintain its own shape. This configuration facilitates handling of the first housing member 41 and the second housing member 51. Consequently, handling of the routing member 40 becomes easier. Furthermore, the strength of each of the first tubular member 42 and the second tubular member 52 can be increased compared to when the first tubular member 42 and the second tubular member 52 do not have rigidity sufficient to maintain its own shape. Therefore, the first tubular member 42 and the second tubular member 52 can easily protect the first electric wire 20 and the second electric wire 30 from foreign objects that come into contact with the wire harness 10 including the routing member 40. For example, when the first tubular member 42 and the second tubular member 52 are routed to pass under the floor of the vehicle V, the first electric wire 20 and the second electric wire 30 can be protected from flying stones.

[0077] (1-3) The first tubular member 42 has a rectangular cross-section with a height that is shorter than its width. The second tubular member 52 has a rectangular cross-section with a height that is shorter than its width or with the width and height being equal. The first tubular member 42 and the second tubular member 52 are arranged side by side in the width direction Y11 of the first tubular member 42 and such that the height direction Z11 of the first tubular member 42 and the height direction Z21 of the second tubular member 52 are parallel to each other.

[0078] This configuration can prevent the routing member 40 from becoming large in the height direction Z11 of the first tubular member 42. Therefore, by arranging the routing member 40 under the floor of the vehicle V so that the height direction Z11 is along the up-down direction of the vehicle V, the space required for arranging the routing member 40 in the up-down direction of the vehicle V can be narrowed.

[0079] (1-4) The second tubular member 52 is contained within the height range A1 of the first tubular member 42 along the height direction Z11 of the first tubular member 42. According to this configuration, the routing member 40 can be made thinner in the height direction Z11 compared to when the second tubular member 52 has a portion that is disposed outside the height range A1 of the first tubular member 42 in the height direction Z11.

[0080] (1-5) The internal space S1 of the first tubular member 42 has a width W1 that allows a plurality of first electric wires 20 to be arranged side by side along the width direction Y11 of the first tubular member 42. According to this configuration, when a plurality of first electric wires 20 penetrate the first tubular member 42, the height of the first tubular member 42 can be prevented from increasing compared to when the plurality of first electric wires 20 are arranged so as to overlap in the height direction Z11 of the first tubular member 42. This can therefore contribute to making the routing member 40 thinner in the height direction Z11.

[0081] (1-6) Each of the first connecting portion 43 and the second connecting portion 53 is located within a height range A1 of the first tubular member 42 and within a height range A2 of the second tubular member 52 along the height direction Z11 of the first tubular member 42. This configuration can prevent the routing member 40 from becoming larger in size in the height direction Z11.

[0082] (1-7) The first tubular member 42 has a side wall 42a at one end of the first tubular member 42 in the width direction Y11 of the first tubular member 42. The second tubular member 52 has a side wall 52b facing the side wall 42a. The first connecting portion 43 and the second connecting portion 53 are each located between the side wall 42a and the side wall 52b in the width direction Y11. This configuration makes it possible to prevent at least one of the first connecting portion 43 and the second connecting portion 53 from having a complex shape or from becoming large.

[0083] (1-8) The first tubular member 42 has a side wall 42a at one end of the first tubular member 42 in the width direction Y11 of the first tubular member 42. The second tubular member 52 has a side wall 52b facing the side wall 42a. A connector 63 between the first connecting portion 43 and the second connecting portion 53 is located at the middle of the side wall 42a in the height direction Z11 and at the middle of the side wall 52a in the height direction Z21.

[0084] This configuration can prevent the first tubular member 42 and the second tubular member 52 from rotating relatively around the connector 63. Therefore, it is possible to prevent at least one of the first tubular member 42 and the second tubular member 52 from vibrating.

[0085] (1-9) The first connecting portion 43 protrudes from the side wall 42a toward the side wall 52b. The second connecting portion 53 protrudes from the side wall 52b toward the side wall 42a. The first connecting portion 43 and the second connecting portion 53 are overlapped in the height direction Z11.

[0086] According to this configuration, when connecting the first connecting portion 43 and the second connecting portion 53, it is sufficient to connect the first connecting portion 43 and the second connecting portion 53 that are superimposed in the height direction Z11. Therefore, the first connecting portion 43 and the second connecting portion 53 can be easily connected.

[0087] (1-10) The first connecting portion 43 has a first bolt hole 44 penetrating in the height direction Z11. The second connecting portion 53 has a second bolt hole 54 penetrating in the height direction Z21. The first bolt hole 44 and the second bolt hole 54 of the second connecting portion 53 that is superimposed on the first connecting portion 43 having the first bolt hole 44 are aligned in the height direction Z11.

[0088] According to this configuration, the first connecting portion 43 and the second connecting portion 53 can be more easily connected using a bolt 61 that is passed through the first bolt hole 44 and the second bolt hole 54 and a nut 62 that is fitted onto the bolt 61.

[0089] (1-11) The wire harness 10 includes a routing member 40, at least one first electric wire 20 passing through a first tubular member 42, and at least one second electric wire 30 passing through a second tubular member 52.

[0090] According to this configuration, by connecting the first connecting portion 43 and the second connecting portion 53, the second electric wire 30 passing through the second tubular member 52 can be easily routed along the first electric wire 20 passing through the first tubular member 42. In other words, the second electric wire 30 used to supply power from the low-voltage battery can be easily routed along the first electric wire 20 used to supply power from the high-voltage battery.

[0091] Second Embodiment Hereinafter, a second embodiment of the wiring member and the wire harness will be described. In this second embodiment, the same components as or corresponding to those in the first embodiment are denoted by the same reference numerals, and the description of those components will be omitted in part or in whole.

[0092] (Wire harness 10A configuration) 4 and 5, a wire harness 10A of the second embodiment includes a wiring member 40A instead of the wiring member 40 of the first embodiment. Note that FIG. 5 is a cross-sectional view taken along line 5-5 in FIG.

[0093] (Configuration of wiring member 40A) The routing member 40A includes a first housing member 41A and a second housing member 51A. (Configuration of first storage member 41A) The first accommodating member 41A is arranged in the vehicle V in the same manner as the first accommodating member 41 of the first embodiment. The first accommodating member 41A has the first tubular member 42 of the first embodiment and at least one first connecting portion 43A provided integrally with the first tubular member 42.

[0094] The first tubular member 42 has a side wall 42c at one end of the first tubular member 42 in the height direction Z11. The side wall 42c corresponds to the "first connecting side wall." Of the two side walls 42c, 42d at both ends of the first tubular member 42 in the height direction Z11, the side wall 42c is located closer to the front in the height direction Z11 than the side wall 42d. The side wall 42a corresponds to the "first side wall."

[0095] The first housing member 41A has, for example, a plurality of first connecting portions 43A. The first connecting portions 43A are provided, for example, in a plurality of locations on the first tubular member 42 at intervals of several tens of centimeters (for example, at intervals of 50 to 100 cm) along the longitudinal direction X11. Each of the first connecting portions 43A is, for example, integrally provided with the side wall 42c. Each of the first connecting portions 43A protrudes in the height direction Z11 from, for example, an end region of the side wall 42c opposite the height direction Z11. Each of the first connecting portions 43A has, for example, a flat plate shape perpendicular to the width direction Y11. Each of the first connecting portions 43A may have a first bolt hole 44A penetrating in the width direction Y11.

[0096] (Configuration of second accommodating member 51A) The second accommodating member 51A has the second tubular member 52 of the first embodiment and at least one second connecting portion 53A provided integrally with the second tubular member 52.

[0097] The second tubular member 52 has a side wall 52c at one end of the second tubular member 52 in the height direction Z21. The side wall 52c corresponds to the "second connecting side wall." Of the two side walls 52c, 52d at both ends of the second tubular member 52 in the height direction Z21, the side wall 52c is located closer to the front in the height direction Z21 than the side wall 52d. In addition, the side wall 52b corresponds to the "second side wall."

[0098] The second accommodating member 51A has, for example, a plurality of second connecting portions 53A. Each second connecting portion 53A is provided at a position overlapping with a corresponding first connecting portion 43A in the width direction Y11. The second connecting portions 53A are provided, for example, at a plurality of locations on the second tubular member 52 at intervals of several tens of centimeters (for example, intervals of 50 to 100 cm) along the longitudinal direction X21. Each second connecting portion 53A is, for example, integrally provided with the side wall 52c. Each second connecting portion 53A protrudes in the height direction Z21 from, for example, an end region of the side wall 42c in the height direction Z21. Each second connecting portion 53A has, for example, a flat plate shape perpendicular to the width direction Y21. Each second connecting portion 53A may have a second bolt hole 54A penetrating in the width direction Y21.

[0099] The second accommodating member 51A is connected to the first accommodating member 41A by connecting each second connecting portion 53A to each first connecting portion 43A. Note that the connection between each first connecting portion 43A and each second connecting portion 53A may be performed before attaching the first accommodating member 41A to the vehicle V, or may be performed after attaching the first accommodating member 41A to the vehicle V.

[0100] The first tubular member 42 and the second tubular member 52 are arranged side by side in the width direction Y11, and are arranged such that the height direction Z11 of the first tubular member 42 and the height direction Z21 of the second tubular member 52 are parallel to each other. Therefore, the width direction Y21 of the second tubular member 52 is the same direction as the width direction Y11 of the first tubular member 42. Furthermore, for example, the second accommodating member 51 is arranged such that the side wall 52b of the second tubular member 52 faces and is in surface contact with the side wall 42a of the first tubular member 42. That is, the second tubular member 52 may have a side wall 52b that faces and is in surface contact with the side wall 42a.

[0101] Each first connecting portion 43A and each second connecting portion 53A are overlapped in the width direction Y11, for example. Each second connecting portion 53A is overlapped on each first connecting portion 43A so as to abut against each first connecting portion 43A, for example. Each first bolt hole 44A penetrates each first connecting portion 43A in the width direction Y11, so each first connecting portion 43A has a first bolt hole 44A that penetrates the first connecting portion 43A in the direction in which the first connecting portion 43A and the second connecting portion 53A overlap. Furthermore, each second bolt hole 54A penetrates each second connecting portion 53A in the width direction Y21, so each second connecting portion 53A has a second bolt hole 54A that penetrates the second connecting portion 53A in the direction in which the first connecting portion 43A and the second connecting portion 53A overlap. The first bolt hole 44A and the second bolt hole 54A of the second connecting portion 53A that is overlapped with the first connecting portion 43A having the first bolt hole 44A are aligned in the overlapping direction of the first connecting portion 43A and the second connecting portion 53A. That is, in the overlapping first connecting portion 43A and second connecting portion 53A, the first bolt hole 44A and the second bolt hole 54A are aligned in the overlapping direction with their penetration directions in the same direction. For example, the first bolt hole 44A and the second bolt hole 54A of the second connecting portion 53A that is overlapped with the first connecting portion 43A having the first bolt hole 44A are aligned in the width direction Y11. A bolt 61 is inserted into the first bolt hole 44 and the second bolt hole 54 that are aligned in the width direction Y11. The overlapping first connecting portion 43A and second connecting portion 53A are connected by a bolt 61 and a nut 62 fitted onto the bolt 61.

[0102] Each second coupling portion 53A is coupled to each first coupling portion 43A and, together with each first coupling portion 43A, maintains the state in which the second tubular member 52 is disposed along the first tubular member 42. Each of the first coupling portion 43A and the second coupling portion 53A has sufficient rigidity to maintain the state in which the second tubular member 52 is disposed along the first tubular member 42. By coupling each second coupling portion 53A to each first coupling portion 43A, at least a portion of the second tubular member 52 in the longitudinal direction X21 is arranged along the first tubular member 42.

[0103] In a state in which the second accommodating member 51 is connected to the first accommodating member 41, the second tubular member 52 is, for example, contained within the height range A1 of the first tubular member 42 along the height direction Z11. In addition, in this state, for example, each of the first connecting portion 43A and the second connecting portion 53A has a portion that is disposed outside the height range A1 of the first tubular member 42 along the height direction Z11.

[0104] According to the second embodiment, in addition to the effects (1-1) to (1-5) and (1-11) of the first embodiment, the following effects can be achieved. (2-1) The first tubular member 42 has a side wall 42a at one end of the first tubular member 42 in the width direction Y11 of the first tubular member 42. The second tubular member 52 has a side wall 52b that faces the side wall 42a and is in surface contact with the side wall 42a.

[0105] According to this configuration, when the first electric wire 20 passing through the first tubular member 42 generates heat due to the passage of electricity, the heat of the first electric wire 20 is transferred to the first tubular member 42 and then transferred from the side wall 42a to the second tubular member 52. Therefore, the heat of the first electric wire 20 can be dissipated from the second tubular member 52 as well, thereby improving the heat dissipation performance of the routing member 40A.

[0106] (2-2) The first tubular member 42 has a side wall 42c at one end of the first tubular member 42 in the height direction Z11 of the first tubular member 42. The second tubular member 52 has a side wall 52c at one end of the second tubular member 52 in the height direction Z21 of the second tubular member 52. The first connecting portion 43A is provided integrally with the side wall 42c. The second connecting portion 53A is provided integrally with the side wall 52c. The first connecting portion 43A and the second connecting portion 53A are overlapped in the width direction Y11 of the first tubular member 42.

[0107] According to this configuration, when connecting the first connecting portion 43A and the second connecting portion 53A, it is sufficient to connect the first connecting portion 43A and the second connecting portion 53A that are superimposed in the width direction Y11. Therefore, the first connecting portion 43A and the second connecting portion 53A can be easily connected.

[0108] (2-3) The first connecting portion 43A has a first bolt hole 44A penetrating the first connecting portion 43A in the direction in which the first connecting portion 43A and the second connecting portion 53A overlap. The second connecting portion 53A has a second bolt hole 54A penetrating the second connecting portion 53A in the direction in which the first connecting portion 43A and the second connecting portion 53A overlap. The first bolt hole 44A and the second bolt hole 54A of the second connecting portion 53A that is overlapped with the first connecting portion 43A having the first bolt hole 44A are aligned in the direction in which the first connecting portion 43A and the second connecting portion 53A overlap. With this configuration, the first connecting portion 43A and the second connecting portion 53A can be more easily connected using a bolt 61 that is passed through the first bolt hole 44A and the second bolt hole 54A and a nut 62 that is fitted onto the bolt 61.

[0109] The above embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other within the scope of technical compatibility. In the second embodiment, the first housing member 41A may further include at least one first connecting portion 43A integrally formed with the side wall 42d. The first connecting portion 43A protrudes in the opposite direction from the height direction Z11, for example, from an end region of the side wall 42d that is opposite the height direction Z11. The second housing member 51A may further include at least one second connecting portion 53A integrally formed with the side wall 52d. The second connecting portion 53A protrudes in the opposite direction from the height direction Z21, for example, from an end region of the side wall 42c in the height direction Z21. In this manner, the second housing member 51 can be connected to the first housing member 41 by connecting the first connecting portion 43A and the second connecting portion 53A that protrude in the height direction Z11 to each other and by connecting the first connecting portion 43A and the second connecting portion 53A that protrude in the opposite direction from the height direction Z11 to each other.

[0110] In the second embodiment, the first connecting portion 43A and the second connecting portion 53A may be overlapped in the longitudinal direction X11. In this case, the first bolt hole 44A penetrates the first connecting portion 43A in the longitudinal direction X11. Furthermore, the second bolt hole 54A penetrates the second connecting portion 53A in the longitudinal direction X21. This configuration can also achieve the same effects as those of (2-3) of the second embodiment.

[0111] In the first embodiment, the first connecting portion 43 and the second connecting portion 53 may be overlapped in the longitudinal direction X11. In this case, each of the first connecting portion 43 and the second connecting portion 53 has, for example, a flat plate shape perpendicular to the longitudinal direction X11. The first bolt hole 44 penetrates the first connecting portion 43 in the longitudinal direction X11. Furthermore, the second bolt hole 54 penetrates the second connecting portion 53 in the longitudinal direction X21.

[0112] In the second embodiment, the side wall 42a and the side wall 52b do not necessarily have to be in surface contact with each other. In the first embodiment, the connector 63 is located at the middle of the side wall 42a in the height direction Z11 and at the middle of the side wall 52b in the height direction Z21. However, the position of the connector 63 in the height direction Z11 is not limited to the position in the first embodiment.

[0113] For example, the wire harness 10B illustrated in FIG. 6 has a connector 63. In FIG. 6, the same reference numerals are used to designate components that are the same as or correspond to those in the first embodiment. The connector 63 differs from the first embodiment in the position of the connector 63 in the height direction Z11. The first connector 43 protrudes from an end region of the side wall 42a in the height direction Z11 toward the side wall 52b along the first axis Y1. The second connector 53 is located in an end region of the side wall 52b in the height direction Z21.

[0114] The vehicle V has a body panel 100. The first connecting portion 43 and the second connecting portion 53 are connected to the body panel 100 by, for example, a bolt 61 and a nut 62. In this case, the bolt 61 may be, for example, a stud bolt. The connecting body 63 between the first connecting portion 43 and the second connecting portion 53 is located in an end region of the side wall 42a in the height direction Z11 and is also located in an end region of the side wall 52b.

[0115] In this way, the attachment of the wire harness 10B to the vehicle V and the connection of the second accommodating member 51 to the first accommodating member 41 can be performed simultaneously. The first connecting portion 43 may be provided on the side wall 42b or the side wall 42d, and the second connecting portion 53 may be provided on the side wall 52a or the side wall 52d.

[0116] The shape of each of the first connecting portion 43, the second connecting portion 53, the first connecting portion 43A, and the second connecting portion 53A is not limited to a plate shape, and may be a three-dimensional shape other than a plate shape. In the first embodiment, the first connecting portion 43 and the second connecting portion 53 do not necessarily have to be connected by the bolt 61 and the nut 62. The first connecting portion 43 and the second connecting portion 53 may be connected by, for example, a fixing pin. The same applies to the first connecting portion 43A and the second connecting portion 53A in the second embodiment.

[0117] For example, a wire harness 10C illustrated in FIGS. 7 and 8 includes a routing member 40C instead of the routing member 40 of the first embodiment. In FIGS. 7 and 8, the same reference numerals are used to designate the same or corresponding components as those of the first embodiment. FIG. 8 is a cross-sectional view taken along line 8-8 in FIG. 7. The routing member 40C includes a first accommodating member 41C and a second accommodating member 51C. The first accommodating member 41C includes the first tubular member 42 of the first embodiment and at least one first coupling portion 43C integrally formed with the first tubular member 42. The second accommodating member 51C includes the second tubular member 52 of the first embodiment and at least one second coupling portion 53C integrally formed with the second tubular member 52.

[0118] The first connecting portion 43C has a plurality of connecting recesses 71 recessed in the width direction Y11 on the side wall 42a. The connecting recesses 71 are arranged at intervals in the longitudinal direction X11. Both end surfaces of each connecting recess 71 in the longitudinal direction X11 have fitting recesses 72 recessed in the longitudinal direction X11 or in the direction opposite to the longitudinal direction X11.

[0119] The second connecting portion 53C has a plurality of connecting protrusions 81 that are inserted into the connecting recesses 71. Each connecting recess 71 protrudes from the side wall 52b in the height direction Z21. The multiple connecting protrusions 81 are arranged at intervals in the longitudinal direction X21. Each connecting protrusion 81 has, on both end surfaces in the longitudinal direction X21, a fitting protrusion 82 that protrudes in the direction opposite to the longitudinal direction X21 or in the longitudinal direction X21. The second connecting portion 53C is connected to the first connecting portion 43C by fitting each fitting protrusion 82 into each fitting recess 72 and inserting each connecting protrusion 81 into each connecting recess 71.

[0120] In the first embodiment, each of the first connecting portion 43 and the second connecting portion 53 does not have to fall within the height range A1 of the first tubular member 42 in the height direction Z11. Each of the first connecting portion 43 and the second connecting portion 53 does not have to fall within the height range A2 of the second tubular member 52 in the height direction Z11.

[0121] The internal space S1 of the first tubular member 42 does not have to have a width W1 that allows multiple first electric wires 20 to be arranged side by side along the width direction Y11. The internal space S1 may have a width that allows multiple first electric wires 20 to be arranged side by side along the height direction Z11, for example.

[0122] The second tubular member 52 does not have to be within the height range A1 of the first tubular member 42 in the height direction Z11. For example, the second tubular member 52 may have a portion that is positioned outside the height range A1 of the first tubular member 42 in the height direction Z11.

[0123] The height of the second tubular member 52 may be greater than the height of the first tubular member 42. The width of the second tubular member 52 may be greater than the width of the first tubular member 42. In the above embodiments, the first tubular member 42 and the second tubular member 52 are aligned in the width direction Y11 and are arranged such that the height direction Z11 of the first tubular member 42 and the height direction Z21 of the second tubular member 52 are parallel to each other. However, the positional relationship between the first tubular member 42 and the second tubular member 52 is not limited thereto, as long as at least a portion of the second tubular member 52 in the length direction X21 is arranged along the first tubular member 42. For example, the first tubular member 42 and the second tubular member 52 may be aligned in the height direction Z11 and arranged such that the width direction Y11 of the first tubular member 42 and the width direction Y21 of the second tubular member 52 are parallel to each other. Furthermore, for example, the second tubular member 52 may be arranged at a position offset in both the height direction Z11 and the width direction Y11 relative to the first tubular member 42. Furthermore, for example, the first tubular member 42 and the second tubular member 52 may be disposed so that the height direction Z11 and the height direction Z21 intersect.

[0124] The first tubular member 42 may have a rectangular cross-section with equal width and height. The first tubular member 42 may also have a cross-section with any of the following shapes: a polygon other than a rectangle, a circle, an ellipse, a rounded rectangle, and any other shape. Similarly, the first tubular member 42 may have a cross-section with any of the following shapes: a polygon other than a rectangle, a circle, an ellipse, a rounded rectangle, and any other shape.

[0125] In the above embodiments, each of the first tubular member 42 and the second tubular member 52 does not necessarily have to have enough rigidity to maintain its own shape. In the first embodiment described above, the direction opposite to the length direction X11 may be the length direction of the first tubular member 42. Also, the direction opposite to the width direction Y11 may be the width direction of the first tubular member 42. Also, the direction opposite to the height direction Z11 may be the height direction of the first tubular member 42. The direction opposite to the length direction X21 may be the length direction of the second tubular member 52. Also, the direction opposite to the width direction Y21 may be the width direction of the second tubular member 52. Also, the direction opposite to the height direction Z21 may be the height direction of the second tubular member 52. Similar changes may be made in the second embodiment described above.

[0126] In the first embodiment, the wire harness 10 includes two first electric wires 20 and one second electric wire 30. However, the number of first electric wires 20 included in the wire harness 10 may be one or three or more. The number of second electric wires 30 included in the wire harness 10 may be multiple. The same changes may be made in the second embodiment.

[0127] The positional relationship between the electric device M1 and the electric device M2 in the vehicle V may be reversed. The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. 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.
