[0006] Problems to be Solved by the Invention

[0007] However, sometimes multiple wires arranged and laid under the floor branch and extend in the middle part in the longitudinal direction. In this case, it is necessary to fix the branched and extended parts of each wire to the vehicle, and thus the number of fixing parts of each wire to the vehicle may increase. Therefore, there is room for improvement in improving the workability during the laying of the wire harness.

[0008] An object of the present disclosure is to improve the workability during the laying of the wire harness.

[0010] The wire harness of the present disclosure is laid in a vehicle, and the vehicle is equipped with a pipe for liquid flow under the floor. The wire harness includes: a first wire member laid side by side with the pipe; a second wire member laid between the first wire member and the pipe. The second wire member has: a conductor formed by stranding a plurality of conductive wire rods; and a metal pipe housing the conductor. The second wire member has: a first section extending along the first wire member; a second section extending along the pipe at a position farther from the first wire member than the first section in the arrangement direction of the pipe and the first wire member; and a third section extending between the first section and the second section.

[0021] [Description of the Embodiment of the Present Disclosure]

[0022] First, the embodiments of the present disclosure will be listed and described.

[0023] The wire harness of the present disclosure,

[0024] [1] is disposed in a vehicle, and the vehicle is equipped with a pipe for liquid circulation under the floor. The wire harness includes: a first wire member disposed in alignment with the pipe; and a second wire member disposed between the first wire member and the pipe. The second wire member has: a conductor formed by stranding a plurality of wire materials having conductivity; and a metal pipe for housing the conductor. The second wire member has: a first section extending along the first wire member; a second section extending along the pipe at a position farther from the first wire member than the first section in the arrangement direction of the pipe and the first wire member; and a third section extending between the first section and the second section. The pipe extends so as to include the third section.

[0025] When laying a wire member having a portion extending along the first wire member and a portion extending along the pipe, if it is difficult for the wire member to maintain its own shape, there is a possibility that the wire member increases the fixed parts to the vehicle.

[0026] In this regard, according to the above configuration, the second wire member has a tube extending in a manner including the third section, so it is easy to maintain its shape along its laying path. Therefore, it is also possible not to fix the second wire member to the vehicle in the third section. Thus, the workability during the laying of the wire harness can be improved.

[0027] [2]Preferably, the second wire member is fixed to the first wire member in the first section.

[0028] According to this configuration, the second wire member is fixed to the first wire member in the first section where it extends along the first wire member. Therefore, when fixing the wire harness to the vehicle in the first section, compared with the case of fixing the first wire member and the second wire member to the vehicle separately, the fixing members and fixing parts for fixing the wire harness to the vehicle can be reduced. Thus, the workability during the laying of the wire harness can be improved.

[0029] [3]Preferably, the second wire member is fixed to the pipe in the second section.

[0030] According to this configuration, the second wire member is fixed to the pipe in the second section where it extends along the pipe. Therefore, when fixing the wire harness to the vehicle in the second section, compared with the case of fixing the pipe and the second wire member to the vehicle separately, the fixing members and fixing parts for fixing the wire harness to the vehicle can be reduced. Thus, the workability during the laying of the wire harness can be improved.

[0031] [4]Preferably, a wire-side fixing member is provided, which fixes the first wire member and the second wire member together to a fixing object of the vehicle, and the wire-side fixing member is provided in the first section.

[0032] According to this configuration, since the wire-side fixing member is provided in the first section, the first wire member and the second wire member are fixed together to the fixing object in the first section. Therefore, compared with the case of fixing the first wire member and the second wire member to the fixing object separately in the first section, the fixing members and fixing parts for fixing the wire harness to the vehicle can be reduced. Thus, the workability during the laying of the wire harness can be improved.

[0033] [5]Preferably, the wire-side fixing member has: a main holding portion that holds the first wire member; and a sub-holding portion that holds the second wire member. The main holding portion has a main insertion opening that opens in a direction orthogonal to the longitudinal direction of the first wire member and can insert the first wire member. The sub-holding portion has a sub-insertion opening that opens in a direction orthogonal to the longitudinal direction of the second wire member and can insert the second wire member. In the state of being fixed to the fixing object, the sub-insertion opening opens in a direction not facing the fixing object.

[0034] According to this configuration, for the sub-holding portion of the wire-side fixing member that fixes the first wire member in a fixed state to the fixing object, the second wire member can be installed later. Thus, compared with the case of fixing an integrated component in which the first wire member and the second wire member are assembled in the fixing member to the fixing object, the workability during the wiring harness layout can be improved.

[0035] [6] Preferably, a pipe-side fixing member is provided, which fixes the pipe and the second wire member together to the fixing object of the vehicle, and the pipe-side fixing member is provided in the second section.

[0036] According to this configuration, since the pipe-side fixing member is provided in the second section, the pipe and the second wire member are fixed together to the fixing object in the second section. Therefore, compared with the case of fixing the pipe and the second wire member to the fixing object separately in the second section, the fixing members and fixing parts for fixing the wiring harness to the vehicle can be reduced. Thus, the workability during the wiring harness layout can be improved.

[0037] [7] Preferably, the pipe-side fixing member has: a main holding portion that holds the pipe; and a sub-holding portion that holds the second wire member. The main holding portion of the pipe-side fixing member has a main insertion opening that opens in a direction orthogonal to the longitudinal direction of the pipe and can insert the pipe. The sub-holding portion of the pipe-side fixing member has a sub-insertion opening that opens in a direction orthogonal to the longitudinal direction of the second wire member and can insert the second wire member. In the state of being fixed to the fixing object, the sub-insertion opening of the pipe-side fixing member opens in a direction not facing the fixing object.

[0038] According to this configuration, for the sub-holding portion of the pipe-side fixing member that fixes the pipe in a fixed state to the fixing object, the second wire member can be installed later. Thus, compared with the case of fixing an integrated component in which the pipe and the second wire member are assembled in the fixing member to the fixing object, the workability during the wiring harness layout can be improved.

[0039] [8] Preferably, in the state of the vehicle laid out in a horizontal state, the lowermost portion of the second wire member is above the lowermost portion of the first wire member.

[0040] According to this configuration, in the wiring harness of the vehicle laid out in a horizontal state, the first wire member is below the second wire member. Thus, by providing the second wire member, the distance from the ground to the lowest portion of the vehicle with the wiring harness laid out, that is, the so-called minimum ground clearance, can be prevented from becoming smaller.

[0041] [9]Preferably, in a state where the vehicle is disposed in a horizontal state, the lowermost portion of the second wire member is positioned above the lowermost portion of the pipe.

[0042] According to this configuration, in the wiring harness of the vehicle disposed in a horizontal state, the pipe is positioned below the second wire member. Thus, by providing the second wire member, it is possible to suppress a decrease in the distance from the ground to the lowest portion of the vehicle provided with the wiring harness, that is, the so-called minimum ground clearance.

[0043] [Details of Embodiments of the Present Disclosure]

[0044] Hereinafter, a specific example of the wiring harness of the present disclosure will be described with reference to the Figure 1 drawings. In each drawing, for convenience of explanation, a part of the configuration may be enlarged or simplified and shown. In addition, the dimensional ratios of the respective parts may be different in each drawing. Furthermore, the present disclosure is not limited to these examples, but is shown in the claims and is intended to include all modifications within the meaning and scope equivalent to the claims. In the present specification, "orthogonal" includes not only the case where it is strictly orthogonal, but also the case where it is substantially orthogonal within the range where the effects of the present embodiment are achieved.

[0045] [Configuration of Vehicle V]

[0046] Referring to Figure 1 and Figure 2 , first, the vehicle V provided with the wiring harness 10 of the present embodiment will be described. The vehicle V is, for example, a hybrid vehicle, an electric vehicle, or the like.

[0047] A cylindrical pipe 90 through which a liquid flows is assembled under the floor of the vehicle V. The pipe 90 of the present embodiment is, for example, a brake pipe that is used to apply hydraulic pressure to a caliper (not shown) of each wheel W to brake each wheel W by allowing brake fluid to flow inside. The pipe 90 is formed of a metal material such as an aluminum-based material, for example.

[0048] Here, Figure 1 the left-right direction in Figure 2 is the vehicle front-rear direction, Figure 1 the up-down direction in Figure 2 is the vehicle width direction, and Figure 2 the up-down direction in

[0049] The pipe line 90 is laid out from the master cylinder 91 to the calipers of the respective wheels W in such a way that a part of it in the longitudinal direction thereof passes under the floor of the vehicle V.

[0050] The pipe line 90 extends along the Y-axis direction at a position biased to the left from the central part in the X-axis direction in the vehicle V, and branches at positions corresponding to the respective wheels W in the Y-axis direction and extends toward the respective calipers.

[0051] (Overall structure of the wire harness 10)

[0052] As Figure 1 and Figure 2 shown, the wire harness 10 includes a first wire member 20 that electrically connects the first machine M1 and the second machine M2 mounted on the vehicle V, and a second wire member 30 that electrically connects the third machine M3 and the fourth machine M4. In addition, the wire harness 10 includes a wire-side fixing member 40 for fixing the first wire member 20 and the second wire member 30 to the vehicle V, and a plurality of pipe-side fixing members 70 for fixing the pipe line 90 and the second wire member 30 to the vehicle V.

[0053] The first wire member 20 is laid out from the first machine M1 along the Y-axis direction to the second machine M2 in such a way that a part of it in the longitudinal direction thereof passes under the floor of the vehicle V. The first wire member 20 is laid out in parallel with the pipe line 90.

[0054] As an example of the first machine M1 and the second machine M2, the first machine M1 is an inverter disposed at the front part of the vehicle V, and the second machine M2 is a high-voltage battery disposed at the rear part of the vehicle V. The first machine M1 as the inverter is connected to, for example, an electric motor for driving wheels (not shown) that serves as a power source for vehicle running. The inverter generates alternating current power from the direct current power of the high-voltage battery and supplies the alternating current power to the electric motor. The second machine M2 as the high-voltage battery is, for example, a battery capable of supplying a voltage of 100 volts or more.

[0055] The second wire member 30 is laid out from the third machine M3 to the fourth machine M4 in such a way that a part of it in the longitudinal direction thereof passes under the floor of the vehicle V. The second wire member 30 is laid between the first wire member 20 and the pipe line 90. As an example of the third machine M3 and the fourth machine M4, the third machine M3 is a relay box disposed at the front part of the vehicle V, and the fourth machine M4 is a low-voltage battery disposed at the rear part of the vehicle V. The relay box distributes the voltage of the low-voltage battery to various machines mounted on the vehicle V.

[0056] (Structure of the first wire member 20)

[0057] As Figure 3As shown, the first wire member 20 has two first wires 21 and a metal tube 24 that houses each first wire 21. The first wire 21 has a first conductor 22 and a first insulating coating portion 23 that coats the outer periphery of the first conductor 22.

[0058] The first conductor 22 is a columnar single-core wire with a solid structure inside. As the material of the first conductor 22, metal materials such as copper-based and aluminum-based can be used. The first conductor 22 is formed, for example, by extrusion molding.

[0059] The cross-sectional shape of the first conductor 22 that is orthogonal to the length direction, i.e., the cross-sectional shape, can be set to any shape. The cross-sectional shape of the first conductor 22 can be formed, for example, into a circular shape, a semi-circular shape, a polygonal shape, a square shape, or a flat shape.

[0060] The first insulating coating portion 23 coats the outer peripheral surface of the first conductor 22 over the entire circumference, for example. The first insulating coating portion 23 is made of a resin material such as a cross-linked polyethylene-based material, for example. The first insulating coating portion 23 is formed, for example, by extrusion molding for the first conductor 22.

[0061] The tube 24 forms a long cylindrical shape as a whole. The outer diameter of the tube 24 is larger than the outer diameter of the pipeline 90. The tube 24 is a member that protects the first wire 21 from flying objects and water droplets, for example.

[0062] As the material of the tube 24, metal materials such as copper-based and aluminum-based can be used. The tube 24 of this embodiment has rigidity that can maintain its shape by itself.

[0063] Here, "rigidity" in this specification refers to the degree of difficulty of deformation of an object with respect to bending force and the like. And "rigidity that can maintain its shape by itself" means the property that an object is not likely to sag due to its own weight.

[0064] In addition, the first wire 21 is not housed in the tube 24 over the entire longitudinal direction, but near both ends of the first wire 21 connected to the first machine M1 and the second machine M2, it is covered with an outer covering member that is softer than the tube 24. In addition, at both ends, a conductor such as a stranded wire that is softer than the first conductor 22 is connected to the first conductor 22. In addition, as the above-mentioned outer covering member, for example, a wire sleeve, a corrugated pipe, etc. can be cited.

[0065] (Configuration of the second wire member 30)

[0066] As Figure 3 shown, the second wire member 30 has a second wire 31 and a metal tube 34 that houses the second wire 31. The second wire 31 has a second conductor 32 and a second insulating coating portion 33 that coats the outer periphery of the second conductor 32. The second conductor 32 is an example of a conductor.

[0067] The second conductor 32 is a stranded wire formed by stranding a plurality of conductive wire rods. As the material of the second conductor 32, metallic materials such as copper-based and aluminum-based materials can be used.

[0068] The cross-sectional shape of the second conductor 32 orthogonal to the length direction, that is, the cross-sectional shape, can be set to any shape. The cross-sectional shape of the second conductor 32 can be formed into, for example, a circular shape, a semi-circular shape, a polygonal shape, a square shape, or a flat shape.

[0069] The second insulating coating portion 33 covers the outer peripheral surface of the second conductor 32 over the entire circumference, for example. The second insulating coating portion 33 is formed of a resin material such as a crosslinked polyethylene-based material, for example. The second insulating coating portion 33 can be formed by extrusion molding for the second conductor 32, for example.

[0070] The tube 34 is formed in a long cylindrical shape as a whole. The outer diameter of the tube 34 is smaller than the outer diameter of the pipeline 90 and the outer diameter of the tube 24 of the first wire member 20. The tube 34 is a member that protects the second wire 31 from flying objects and water droplets, for example.

[0071] As the material of the tube 34, metallic materials such as copper-based and aluminum-based materials can be used. The tube 34 of the present embodiment has rigidity that can maintain its shape by itself.

[0072] As shown Figure 2 The second wire member 30 has: a first section 30A that extends along the first wire member 20; and a second section 30B that extends along the pipeline 90 at a position farther from the first wire member 20 than the first section 30A in the arrangement direction of the pipeline 90 and the first wire member 20. In addition, the second wire member 30 has a third section 30C that extends between the first section 30A and the second section 30B.

[0073] In the present embodiment, the first section 30A is provided on the front side of the vehicle V, and the second section 30B is provided on the rear side of the vehicle V. The third section 30C is located between the front and rear wheels W in the Y-axis direction. The third section 30C extends obliquely so as to be located more to the left as it goes further to the rear side of the vehicle V.

[0074] The tube 34 of the present embodiment extends at least in the first section 30A, the second section 30B, and the third section 30C.

[0075] More specifically, the second wire 31 is not entirely housed in the tube 34 in the longitudinal direction, but near both ends of the second wire 31 connected to the third machine M3 and the fourth machine M4, it is covered with an exterior member that is softer than the tube 34. In addition, as the above exterior member, for example, a wire sleeve, a corrugated pipe, etc. can be cited.

[0076] (Configuration of the wire-side fixing member 40)

[0077] like Figure 4 and Figure 5 As shown, the wire-side fixing member 40 includes a fixing portion 41 fixed to the assembly surface Pa of the panel P, which constitutes the floor portion of the vehicle V; a main retaining portion 51 that retains the first wire member 20; and a secondary retaining portion 61 that retains the second wire member 30. The main retaining portion 51 and the secondary retaining portion 61 are integrally provided on both sides of the fixing portion 41 in the X-axis direction. The wire-side fixing member 40 is a resin molded article formed by injection molding. The panel P is an example of a fixed object.

[0078] The wire-side fixing member 40 fixes the first wire member 20 and the second wire member 30 together to the panel P in the first section 30A. The wire-side fixing member 40 fixes the second wire member 30 to the first wire member 20 in the first section 30A.

[0079] like Figure 5 As shown, the assembly surface Pa of the panel P is configured to be substantially horizontal when the vehicle V is in a horizontal state. A column portion Pb, for example, formed of a stud bolt, projects vertically from the assembly surface Pa.

[0080] like Figure 4 and Figure 5 As shown, an insertion hole 42 into which the post portion Pb is inserted is formed on the upper surface of the fixing portion 41. Furthermore, a pair of contact portions 43 are protrudingly provided around the insertion hole 42 on the upper surface of the fixing portion 41 to contact the assembly surface Pa. The contact portions 43 face each other across the insertion hole 42.

[0081] The fixing portion 41 has a plurality of locking pieces 44 that lock in the protruding direction of the pillars Pb inserted into the fixing portion 41 through the insertion hole 42. The locking pieces 44 lock with the pillars Pb, thereby fixing the fixing portion 41 to the assembly surface Pa.

[0082] (Configuration of the Main Holding Unit 51)

[0083] The main holding portion 51 has an arc-shaped holding surface 52 along the outer peripheral surface of the first electric wire member 20. The outer peripheral surface of the first electric wire member 20 is held by the holding surface 52.

[0084] The main holding portion 51 has a main insertion opening 53 that opens in a direction perpendicular to the longitudinal direction of the first electric wire member 20 and into which the first electric wire member 20 can be inserted. When the wire-side fixing member 40 is fixed to the panel P, the main insertion opening 53 opens in a direction facing the panel P. The first electric wire member 20 is inserted into the main insertion opening 53 from a direction perpendicular to its longitudinal direction.

[0085] A holding piece 54 is formed at the upper end of the main holding part 51, and the holding piece 54 extends toward the central axis of the first wire member 20 held on the holding surface 52. The tip of the holding piece 54 has a circular arc cross-section recessed in a direction away from the first wire member 20 held on the holding surface 52. The tip of the holding piece 54 holds the first wire member 20 held on the holding surface 52 from above.

[0086] The main insertion port 53 of the present embodiment is constituted by the side surface 54a of the holding piece 54 and the side surface 51a of the main holding part 51 opposed to the side surface 54a in the X-axis direction. The side surface 54a of the holding piece 54 and the side surface 51a of the main holding part 51 are inclined so as to approach each other as they face the holding surface 52 side.

[0087] The opening width of the main insertion port 53 in the X-axis direction, that is, the interval between the side surface 54a of the holding piece 54 and the side surface 51a of the main holding part 51, is formed smaller than the outer diameter of the tube 24 of the first wire member 20. When the first wire member 20 is inserted into the main insertion port 53, the opening width is increased by the elastic deformation of the holding piece 54, so that the first wire member 20 is inserted into the main insertion port 53. At this time, the first wire member 20 is guided toward the holding surface 52 by the side surface 54a of the holding piece 54 and the side surface 51a of the main holding part 51.

[0088] (Configuration of the sub-holding part 61)

[0089] The sub-holding part 61 has an arc-shaped holding surface 62 along the outer peripheral surface of the second wire member 30. In addition, the sub-holding part 61 has a sub-insertion port 63 that opens in a direction orthogonal to the longitudinal direction of the second wire member 30 and into which the second wire member 30 can be inserted. In a state where the wire-side fixing member 40 is fixed to the panel P, the sub-insertion port 63 opens in a direction not facing the panel P. In the present embodiment, the wire-side fixing member 40 is fixed to the panel P such that the sub-insertion port 63 opens to the left. The second wire member 30 is inserted into the sub-insertion port 63 from a direction orthogonal to its longitudinal direction.

[0090] A pair of holding pieces 64 are formed at one end of the sub-holding part 61 in the X-axis direction, and the pair of holding pieces 64 extend toward the central axis of the second wire member 30 held on the holding surface 62. The tip of each holding piece 64 has a circular arc cross-section recessed in a direction away from the second wire member 30 held on the holding surface 62. The tip of each holding piece 64 holds the second wire member 30 held on the holding surface 62 from one side in the X-axis direction.

[0091] The sub-insertion port 63 of the present embodiment is constituted by the side surfaces 64a of the respective holding pieces 64 opposed to each other in the Z-axis direction. Each side surface 64a is inclined so as to approach each other as it faces the holding surface 62 side.

[0092] The opening width in the Z-axis direction of the sub-insertion port 63, that is, the interval between the side surfaces 64a of the respective holding pieces 64, is formed smaller than the outer diameter of the tube 34 of the second wire member 30. When the second wire member 30 is inserted into the sub-insertion port 63, the above-mentioned opening width becomes larger due to the elastic deformation of the respective holding pieces 64, so that the second wire member 30 is inserted into the sub-insertion port 63. At this time, the second wire member 30 is guided by the side surfaces 64a of the respective holding pieces 64 toward the holding surface 62.

[0093] As Figure 5 shown, in the wiring harness 10 fixed to the panel P of the vehicle V in a horizontal state, the lowermost part of the second wire member 30 is located above the lowermost part of the first wire member 20. That is, the height H2 of the second wire member 30 measured from the ground G is higher than the height H1 of the first wire member 20 measured from the ground G.

[0094] (Configuration of the pipe-side fixing member 70)

[0095] The pipe-side fixing member 70 has the same configuration as the wire-side fixing member 40. Therefore, in the description of the pipe-side fixing member 70, the same reference numerals are given to the same configurations as those of the wire-side fixing member 40. In addition, for the configurations corresponding to those of the wire-side fixing member 40, reference numerals obtained by adding "30" to the reference numerals "5*" representing the configurations of the wire-side fixing member 40 are given as "8*", whereby repeated descriptions are sometimes omitted.

[0096] As Figure 6 shown, the pipe-side fixing member 70 has: a fixing portion 41 fixed to the assembling surface Pa of the panel P of the vehicle V; a main holding portion 81 for holding the pipe 90; and a sub-holding portion 61 for holding the second wire member 30.

[0097] The pipe-side fixing member 70 is a member for fixing the pipe 90 and the second wire member 30 to the panel P together in the second section 30B. By using the pipe-side fixing member 70, the second wire member 30 is fixed to the pipe 90 in the second section 30B. As Figure 2 shown, in the present embodiment, two pipe-side fixing members 70 are provided at intervals in the Y-axis direction.

[0098] In the present embodiment, the pipe-side fixing member 70 is fixed to the panel P in such a manner that the sub-insertion port 63 opens to the right.

[0099] In the wiring harness 10 fixed to the panel P of the vehicle V in a horizontal state, the lowermost part of the second wire member 30 is located above the lowermost part of the pipe 90. That is, the height H2 of the second wire member 30 measured from the ground G is higher than the height H3 of the pipe 90 measured from the ground G.

[0100] As described above, in the wiring harness 10 on the panel P of the vehicle V fixed in the horizontal state, among the heights H1 to H3 of the first wire member 20, the second wire member 30, and the pipe 90 from the ground G, the relationship H1 < H3 < H2 holds.

[0101] (Fixing step of the wiring harness 10)

[0102] Next, the steps of fixing the wiring harness 10 of the present embodiment to the panel P will be described.

[0103] First, the fixing step of the wiring harness 10 in the first section 30A will be described.

[0104] First, the first wire member 20 is assembled to the main holding portion 51 of the wire-side fixing member 40. At this time, with respect to the main insertion port 53 of the main holding portion 51, the first wire member 20 is inserted from a direction orthogonal to its longitudinal direction. At this time, the first wire member 20 abuts against the side surface 54a of the holding piece 54 and the side surface 51a of the main holding portion 51 that form the main insertion port 53. As a result, the holding piece 54 flexes so as to retreat from the first wire member 20. And when the first wire member 20 is inserted to the position held by the holding surface 52, the holding piece 54 elastically restores, and thus the first wire member 20 is held by the holding surface 52 and the holding piece 54.

[0105] After the first wire member 20 is assembled to the main holding portion 51 of the wire-side fixing member 40, the fixing portion 41 of the wire-side fixing member 40 is fixed to the column portion Pb. At this time, each abutting portion 43 of the fixing portion 41 abuts against the assembling surface Pa.

[0106] Next, the second wire member 30 is assembled to the sub-holding portion 61 of the wire-side fixing member 40. At this time, with respect to the sub-insertion port 63 of the sub-holding portion 61, the second wire member 30 is inserted from a direction orthogonal to its longitudinal direction, more specifically from the left side. At this time, the second wire member 30 abuts against the side surfaces 64a of the respective holding pieces 64 that form the sub-insertion port 63. As a result, the respective holding pieces 64 flex so as to retreat from the second wire member 30. And when the second wire member 30 is inserted to the position held by the holding surface 62, the respective holding pieces 64 elastically restore, and thus the second wire member 30 is held by the holding surface 62 and the respective holding pieces 64.

[0107] In this way, in the first section 30A, the first wire member 20 and the second wire member 30 are fixed to the panel P together.

[0108] Next, regarding the fixing step of the wiring harness 10 in the second section 30B, the description will be centered on the differences from the fixing step of the wiring harness 10 in the above-mentioned first section 30A.

[0109] First, assemble the pipeline 90 to the main holding part 81 of the pipeline-side fixing member 70. At this time, for the main insertion port 83 of the main holding part 81, insert the pipeline 90 from a direction orthogonal to its longitudinal direction. At this time, the pipeline 90 abuts against the side surface 84a of the holding piece 84 constituting the main insertion port 83 and the side surface 81a of the main holding part 81. Thereby, the holding piece 84 flexes in a manner of retreating from the pipeline 90. And when the pipeline 90 is inserted to the position held by the holding surface 82, the holding piece 84 elastically restores, so that the pipeline 90 is held by the holding surface 82 and the holding piece 84.

[0110] After assembling the pipeline 90 to the main holding part 81 of the pipeline-side fixing member 70, fix the fixing part 41 of the pipeline-side fixing member 70 to the column part Pb. At this time, each abutting part 43 of the fixing part 41 abuts against the assembling surface Pa.

[0111] Next, assemble the second wire member 30 to the sub-holding part 61 of the pipeline-side fixing member 70. In subsequent steps, it is the same as the fixing step of the second wire member 30 in the first section 30A. However, the second wire member 30 is inserted from the right side of the sub-holding part 61.

[0112] In this way, in the second section 30B, the pipeline 90 and the second wire member 30 are fixed to the panel P together.

[0113] In this way, in the present embodiment, for the wire-side fixing member 40 holding the first wire member 20 and the pipeline-side fixing member 70 holding the pipeline 90, the second wire member 30 can be installed later.

[0114] Explain the functions and effects of the present embodiment.

[0115] (1) The wire harness 10 includes: a first wire member 20 arranged side by side with the pipeline 90; and a second wire member 30 arranged between the first wire member 20 and the pipeline 90. The second wire member 30 has: a first section 30A extending along the first wire member 20; a second section 30B extending along the pipeline 90 at a position farther from the first wire member 20 than the first section 30A in the arrangement direction of the pipeline 90 and the first wire member 20; and a third section 30C extending between the first section 30A and the second section 30B. The metal pipe 34 constituting the second wire member 30 extends in a manner including the third section 30C.

[0116] When laying a wire member having a part extending along the first wire member 20 and a part extending along the pipeline 90, in the case where it is difficult for the above-mentioned wire member to maintain its own shape, it is possible that the wire member increases the fixed parts to the vehicle V.

[0117] In this regard, according to the above configuration, since the second wire member 30 has the tube 34 extending in a manner including the third section 30C, it is easy to maintain its shape along its laying path. Thus, it is not necessary to fix the second wire member 30 to the vehicle V in the third section 30C. Therefore, the workability during the laying of the wire harness 10 can be improved.

[0118] (2) The second wire member 30 is fixed to the first wire member 20 in the first section 30A.

[0119] According to such a configuration, the second wire member 30 is fixed to the first wire member 20 in the first section 30A that extends along the first wire member 20. Therefore, when fixing the wire harness 10 to the vehicle V in the first section 30A, compared with the case of fixing the first wire member 20 and the second wire member 30 to the vehicle V separately, the fixing members and fixing parts for fixing the wire harness 10 to the vehicle V can be reduced. Therefore, the workability during the laying of the wire harness 10 can be improved.

[0120] (3) The second wire member 30 is fixed to the pipe 90 in the second section 30B.

[0121] According to such a configuration, the second wire member 30 is fixed to the pipe 90 in the second section 30B that extends along the pipe 90. Therefore, when fixing the wire harness 10 to the vehicle V in the second section 30B, compared with the case of fixing the pipe 90 and the second wire member 30 to the vehicle V separately, the fixing members and fixing parts for fixing the wire harness 10 to the vehicle V can be reduced. Therefore, the workability during the laying of the wire harness 10 can be improved.

[0122] (4) The wire-side fixing member 40 is provided in the first section 30A.

[0123] According to such a configuration, since the wire-side fixing member 40 is provided in the first section 30A, the first wire member 20 and the second wire member 30 are fixed to the panel P together in the first section 30A. Therefore, compared with the case of fixing the first wire member 20 and the second wire member 30 to the panel P separately in the first section 30A, the fixing members and fixing parts for fixing the wire harness 10 to the vehicle V can be reduced. Therefore, the workability during the laying of the wire harness 10 can be improved.

[0124] (5) The wire-side fixing member 40 has: a main holding portion 51 that holds the first wire member 20; and a sub-holding portion 61 that holds the second wire member 30. The main holding portion 51 has a main insertion port 53 into which the first wire member 20 can be inserted. The sub-holding portion 61 of the wire-side fixing member 40 has a sub-insertion port 63 into which the second wire member 30 can be inserted. In the state of being fixed to the panel P, the sub-insertion port 63 of the wire-side fixing member 40 opens in a direction not facing the panel P.

[0125] According to such a configuration, for the sub-holding portion 61 of the wire-side fixing member 40 that fixes the state of the first wire member 20 to the panel P, the second wire member 30 can be installed later. Thus, compared with the case of fixing an integrated member in which the first wire member 20 and the second wire member 30 are assembled to the fixing member to the panel P, the workability during the routing of the wire harness 10 can be improved.

[0126] (6) The pipe-side fixing member 70 is provided in the second section 30B.

[0127] According to such a configuration, since the pipe-side fixing member 70 is provided in the second section 30B, the pipe 90 and the second wire member 30 are fixed to the panel P together in the second section 30B. Therefore, compared with the case of fixing the pipe 90 and the second wire member 30 to the panel P separately in the second section 30B, the number of fixing members and fixing portions for fixing the wire harness 10 to the vehicle V can be reduced. Thus, the workability during the routing of the wire harness 10 can be improved.

[0128] (7) The pipe-side fixing member 70 has: a main holding portion 81 that holds the pipe 90; and a sub-holding portion 61 that holds the second wire member 30. The main holding portion 8l has a main insertion port 83 into which the pipe 90 can be inserted. The sub-holding portion 61 of the pipe-side fixing member 70 has a sub-insertion port 63 into which the second wire member 30 can be inserted. In the state of being fixed to the panel P, the sub-insertion port 63 of the pipe-side fixing member 70 opens in a direction not facing the panel P.

[0129] According to such a configuration, for the sub-holding portion 61 of the pipe-side fixing member 70 that fixes the state of the pipe 90 to the panel P, the second wire member 30 can be installed later. Thus, compared with the case of fixing an integrated member in which the pipe 90 and the second wire member 30 are assembled to the fixing member to the panel P, the workability during the routing of the wire harness 10 can be improved.

[0130] (8) In the state of the vehicle V being routed in a horizontal state, the lowermost portion of the second wire member 30 is located above the lowermost portion of the first wire member 20.

[0131] According to such a configuration, in the wire harness 10 of the vehicle V routed in a horizontal state, the first wire member 20 is located below the second wire member 30. Thus, by providing the second wire member 30, it is possible to prevent the distance from the ground G to the lowest portion of the vehicle V in which the wire harness 10 is routed, that is, the so-called minimum ground clearance, from becoming smaller.

[0132] (9) In the state of the vehicle V being routed in a horizontal state, the lowermost portion of the second wire member 30 is located above the lowermost portion of the pipe 90.

[0133] With such a configuration, in the wiring harness 10 of the vehicle V disposed in a horizontal state, the pipe 90 is below the second wire member 30. Thus, by providing the second wire member 30, it is possible to prevent the distance from the ground G to the lowest part of the vehicle V provided with the wiring harness 10, that is, the so-called minimum ground clearance, from becoming smaller.
