[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The wiring module of the present disclosure is as follows.

[0011] (1) A wiring module comprising: a wiring member including a first section, a second section, and a third section that are different from one another along the extension direction; a first rigid member attached to the first section; and a second rigid member attached to the second section; wherein a portion including the first section and the first rigid member is designated as a first section, a portion including the second section and the second rigid member is designated as a second section, and a portion including the third section is designated as a third section; the first section, the second section, and the third section are different from one another; the third section has a section located between the first section and the second section; the third section has foldable bendability; the rigidity of the first rigid member is higher than the rigidity of the second rigid member; and the second section is easier to bend than the first section and harder to bend than the third section.

[0012] According to the wiring module (1), by folding the third section at a portion located between the first and second sections, the wiring module can be folded so that the first and second sections, each provided with a rigid member, overlap. Because the first section is more difficult to bend than the second and third sections, the folded wiring module is less likely to bend when the first section is held while being carried in, making the wiring module easier to carry. When the second section of the wiring module in its folded state after carrying in is unfolded with the first section in a predetermined position, the second section is provided with a second rigid member, making it easier to unfold. Furthermore, because the second section is easier to bend than the first section, a portion of the unfolded second section that deviates from the predetermined path can be easily deformed to follow the predetermined path. These features facilitate carrying in the wiring module and arranging it along the predetermined path.

[0013] (2) In the wiring module of (1), the first section may include a section disposed on a vehicle floor, the second section may include a section disposed along a pillar of the vehicle, and the third section may include a section disposed along a wheelhouse of the vehicle. This makes it easy to carry in the wiring modules disposed on the vehicle floor and in sections adjacent to the floor and to arrange them along a predetermined route.

[0014] (3) The wiring module of (2) further includes a silencer covering the floor of the vehicle, the silencer including a wiring arrangement portion on which the first section is arranged and which serves as the first rigid member, and a main body portion that is continuous with the wiring arrangement portion and is more flexible than the wiring arrangement portion. This allows the silencer to provide rigidity to the first section while integrating the silencer and the wiring member.

[0015] (4) In the wiring module of (3), before being attached to the vehicle, the silencer may be foldable along a fold provided on the main body portion, and by folding at the third portion, the second portion located outside the silencer may be wrapped in the folded silencer. Because the silencer is foldable, the wiring module can be made compact, making it easier to insert the wiring module into the vehicle through a side opening for a side door or a rear opening of the vehicle. Furthermore, because the portion located outside the silencer can be folded at the third portion and wrapped in the folded silencer, sagging and getting caught on the wiring member during transportation of the wiring module are suppressed, making it easier to transport the wiring module.

[0016] (5) In the wiring module of (4), the fold may be provided in a middle portion along the longitudinal direction of the vehicle so as to extend in the left-right direction of the vehicle, the third portion may be provided at the position of the fold, and the first portion may be provided on each of the front and rear sides of the vehicle, sandwiching the fold. This makes it easy to transport the silencer through a side opening for a vehicle side door so that the left-right direction of the silencer coincides with the left-right direction of the vehicle. This makes it easy to position the silencer on the floor after transport.

[0017] (6) In the wiring module of (4), the fold may be provided in a middle portion along the left-right direction of the vehicle so as to extend in the front-rear direction of the vehicle. This makes it easy to provide the first portion continuously and without interruption from the front end to the rear end of the silencer in the front-rear direction of the vehicle.

[0018] (7) In the wiring module of any one of (1) to (6), the second rigid member may be a resin sheet material, which allows the second rigid member to be easily formed.

[0019] (8) In the wiring module of any one of (1) to (7), the wiring member may include a plurality of linear transmission members, the third portion may include an adhesive tape that binds the plurality of linear transmission members, and the second rigid member may have a higher rigidity than the adhesive tape. This allows the third section of the wiring member to be protected by the adhesive tape. Also, the second section of the wiring member may be protected by the second rigid member that has a higher rigidity than the adhesive tape.

[0020] [Details of the embodiments of the present disclosure] Specific examples of the wiring module of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0021] [Embodiment 1] The wiring module according to the first embodiment will be described below. Fig. 1 is a schematic perspective view showing a vehicle 10 in which a wiring module 20 is arranged and a route of a wiring member 30 in the vehicle 10. Fig. 2 is a plan view showing the wiring module 20 according to the first embodiment. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 2. Fig. 5 is a cross-sectional view taken along line VV in Fig. 2.

[0022] The wiring module 20 includes a wiring member 30, a first rigid member 40, and a second rigid member 50. The first rigid member 40 and the second rigid member 50 are attached to the wiring member 30 at different positions. The wiring module 20 is arranged along a predetermined path in the vehicle 10. In this embodiment, the wiring module 20 is described as being arranged on the floor 11 of the vehicle 10 and in the vicinity thereof.

[0023] First, a description will be given of the vehicle 10 in which the wiring module 20 is disposed. The vehicle 10 includes a floor 11, a roof 12, and pillars 13. The floor 11 and the roof 12 are spaced apart in the height direction of the vehicle 10. The floor 11 extends downward in the passenger compartment. The roof 12 extends upward in the passenger compartment. The pillars 13 extend in the height direction at the outer edges along the left-right direction of the vehicle 10, connecting the floor 11 and the roof 12. Note that in the example shown in FIG. 1, only the side edges of the roof 12 are shown, and other parts of the roof 12 are omitted.

[0024] 1 illustrates a vehicle 10 having pillars 13 including A-pillar 13A, B-pillar 13B, and C-pillar 13C. If the passenger seat located furthest forward in vehicle 10 is defined as seat 1, A-pillar 13A is provided in front of seat 1. If the passenger seat next to seat 1 in the longitudinal direction of vehicle 10 is defined as seat 2, B-pillar 13B is provided between seat 1 and seat 2, and C-pillar 13C is provided behind seat 2.

[0025] The vehicle 10 is provided with a side opening 14A through which a passenger in the first seat gets in and out, and a side opening 14B through which a passenger in the second seat gets in and out. The side opening 14A is an opening surrounded by the floor 11, the roof 12, the A-pillar 13A, and the B-pillar 13B. The side opening 14B is an opening surrounded by the floor 11, the roof 12, the B-pillar 13B, and the C-pillar 13C. Side doors (not shown) are attached to the side openings 14A and 14B in an openable and closable manner.

[0026] The vehicle 10 is also provided with a rear opening 15 and a wheel house 16. A rear window or a rear door (not shown) is attached to the rear opening 15. The width of the rear opening 15 is usually larger than the width of the side openings 14A and 14B. The wheel house 16 is a portion for accommodating wheels. In the example shown in FIG. 1, the wheel house 16 for accommodating rear wheels is depicted as such a wheel house 16. The wheel house 16 is provided behind the side opening 14B.

[0027] In this example, the wiring module 20 has a portion arranged along the floor 11, a portion arranged along the B-pillar 13B, and a portion arranged along the wheel house 16. The portions of the B-pillar 13B and the wheel house 16 where the wiring module 20 is arranged are curved. The wiring module 20 is arranged in a curved shape so as to fit along the curved portions of the B-pillar 13B and the wheel house 16.

[0028] The wiring member 30 in this embodiment is also called a floor harness and is arranged on the floor 11 and its surrounding area. The wiring member 30 extends, for example, from a battery, an ECU, etc. arranged in the front of the vehicle 10, toward each device arranged in the rear of the vehicle 10, while branching out. The wiring member 30 includes a plurality of linear transmission members 31. The plurality of linear transmission members 31 connect the devices of the vehicle 10 to each other. The linear transmission member 31 transmits electricity or light. The linear transmission member 31 has a transmission line body and a coating that covers the transmission line body. Here, the linear transmission member 31 is described as being a coated electric wire having a conductor core wire 31a and a coating 31b. The linear transmission member 31 may be an optical fiber cable. A connector 32, for example, is provided at an end of the linear transmission member 31.

[0029] The wiring member 30 includes a first section 33, a second section 34, and a third section 35. The first section 33, the second section 34, and the third section 35 are different sections along the extension direction. The first rigid member 40 is attached to the first section 33. The first section 33 is the section to which the first rigid member 40 is attached. In this embodiment, the first section 33 includes a section that is disposed on the floor 11 of the vehicle 10. The second rigid member 50 is attached to the second section 34. The second section 34 is the section to which the second rigid member 50 is attached. In this embodiment, the second section 34 includes a section that is disposed along the pillar 13 of the vehicle 10. Neither the first rigid member 40 nor the second rigid member 50 is attached to the third section 35. The third section 35 includes a section located between the first section 33 and the second section 34. Furthermore, in this embodiment, the third section 35 has a section located between two first sections 33, a section located between two second sections 34, and a section located between two first sections 33 and arranged along the wheelhouse 16 of the vehicle 10.

[0030] In the wiring module 20, a portion including the first section 33 and the first rigid member 40 is defined as the first portion 21, a portion including the second section 34 and the second rigid member 50 is defined as the second portion 22, and a portion including the third section 35 is defined as the third portion 23. The first portion 21, the second portion 22, and the third portion 23 are different portions of the wiring module 20. The third portion 23 has flexibility that allows it to be folded. The second portion 22 is more flexible than the first portion 21 and less flexible than the third portion 23.

[0031] The difference in ease of bending will be described in more detail with reference to Fig. 6. Fig. 6 is a diagram for explaining the difference in ease of bending among the first region 21, the second region 22, and the third region 23.

[0032] FIG. 6 shows the first portion 21, the second portion 22, and the third portion 23, each with one end supported. The other end of each of the first portion 21, the second portion 22, and the third portion 23 hangs down differently. The third portion 23 is bent near the support position and hangs down significantly at the other end. The first portion 21 and the second portion 22 are not bent. The first portion 21 remains straight, while the second portion 22 is bent. Both the first portion 21 and the second portion 22 may remain straight. In this case, when the other ends of the first portion 21 and the second portion 22 are pressed, the second portion 22 should bend with a smaller force than the first portion 21. Both the first portion 21 and the second portion 22 may be bent. In this case, the second portion 22 should bend more than the first portion 21.

[0033] The rigidity of the first rigid member 40 is higher than the rigidity of the second rigid member 50. For example, the first rigid member 40 has enough rigidity to maintain a linear shape even when the weight of the linear transmission member 31 is applied. In this embodiment, a protector 40 is provided as the first rigid member 40. The protector 40 includes a protector main body 41 and a lid 42. The protector main body 41 has a bottom plate and a side plate, and the portion surrounded by the bottom plate and the side plate is formed in a groove shape. The linear transmission member 31 fits into this groove. The lid 42 closes the upper opening of the groove.

[0034] The rigidity of the second rigid member 50 is lower than the rigidity of the first rigid member 40. For example, the second rigid member 50 has a rigidity that allows it to maintain a linear shape when no external force is applied, and a flexibility that allows it to bend when pressed. The second rigid member 50 may have a rigidity that allows it to maintain a linear shape even when the weight of the linear transmission member 31 is applied, or may have a rigidity that allows it to bend due to the weight of the linear transmission member 31. The second rigid member 50 only needs to have a rigidity that prevents it from bending due to the weight of the linear transmission member 31.

[0035] In this embodiment, the second rigid member 50 is a resin sheet material 50. Such resin is, for example, POM (polyacetal resin). In the example shown in FIG. 4, the linear transmission member 31 is sandwiched between two sheet materials 50, but the linear transmission member 31 may be attached to a single sheet material 50. Furthermore, the second rigid member 50 may be a member other than the resin sheet material 50. For example, the second rigid member may be a thin metal sheet or the like. Furthermore, for example, the second rigid member may be a tubular member or the like.

[0036] In this embodiment, the third region 23 includes an adhesive tape 60 that binds the plurality of linear transmission members 31 together. The third region 23 is bendable together with the adhesive tape 60. The second rigid member 50 has higher rigidity than the adhesive tape 60. However, the third region 23 does not necessarily have to include the adhesive tape 60. The plurality of linear transmission members 31 may be bound by a binding member other than the adhesive tape 60. Such a binding member may be a flexible resin sheet or a cable tie. The third region 23 may have portions where no exterior member is provided and the plurality of linear transmission members 31 are exposed.

[0037] The first section 33, the second section 34, and the third section 35 include intermediate sections that are not the ends of the wiring member 30. The ends of the wiring member 30 may have flexibility similar to that of the third section 23, so as to bend when connecting the connector 32. The ends of the wiring member 30 may be integrated with the first rigid member 40 or the second rigid member 50, and may be restricted from bending. In this case, the connector 32 provided at the end may be a standby connector.

[0038] In this embodiment, a plurality of (here, three) first sections 33 are provided. The three first sections 33 may be referred to as first sections 33A, 33B, and 33C in order from the front along the longitudinal direction of the vehicle 10. The first sections 33A and 33B are disposed in front of the wheel house 16 on the floor 11, and the first section 33C is disposed behind the wheel house 16. Portions of the first region 21 corresponding to the first sections 33A, 33B, and 33C are referred to as first regions 21A, 21B, and 21C.

[0039] In this embodiment, a plurality of (here, two) second sections 34 are provided. The two second sections 34 may be referred to as second sections 34A and 34B in order from bottom to top along the height direction of the vehicle 10. Portions of the second region 22 corresponding to the second sections 34A and 34B are referred to as second regions 22A and 22B.

[0040] In this embodiment, a plurality of (here, three) third sections 35 are provided. Of the three third sections 35, third section 35A is a section between first section 33A and second section 34A. A branching portion is located in third section 35A, and third section 35A also includes a section between first section 33A and first section 33B. Third section 35B is a section between first section 33B and first section 33C, and is a section disposed along wheel house 16. Third section 35C is a section between second section 34A and second section 34B, and is a section disposed along B-pillar 13B. Portions of third region 23 corresponding to third sections 35A, 35B, and 35C are referred to as third regions 23A, 23B, and 23C.

[0041] The section behind the first section 33C and the section above the second section 34B may be the first section, the second section, or the third section.

[0042] The third section 35 includes a bending path section. The bending path section is a section that is bent and arranged along a bending path in the vehicle 10. Because the third portion 23 is made to be easily bendable, it is also easy to bend along the bending path section. Here, the third section 35B is a bending path section that is bent and arranged along the wheelhouse 16. Also, here, the third section 35A is a bending path section that is bent and arranged from the floor 11 toward the B-pillar 13B.

[0043] The third section 35 may include a folding section. The folding section is a section that is arranged linearly in the vehicle 10 but is made easy to bend so as to be folded when transporting the wiring module 20. For example, the section between the first section 33A and the first section 33B in the third section 35A may be the folding section.

[0044] The paths of the first section 33 and the second section 34 are closer to a straight line than the path of the curved path section. The path of the first section 33 is closer to a straight line than the path of the second section 34. Here, the path of the first section 33 is a straight path.

[0045] The first section 33 and the second section 34 are longer than the third section 35 between the first section 33A and the second section 34. The first section 33 and the second section 34 are continuous with each other over a certain length (for example, a length of 100 mm or more, a length of 200 mm or more, or a length of 300 mm or more).

[0046] The second portion 22 includes a portion that is bent and arranged. The second portion 22 is arranged so as to follow the gently curved pillar 13 (the portion with a large radius of curvature). The second portion 22 has flexibility that allows it to be bent together with the second rigid member 50. The attachment of the second portion 22 will be described in more detail with reference to FIG. 7. FIG. 7 is a diagram illustrating the attachment of the second portion 22.

[0047] As shown by the imaginary lines in Figure 7, the second portion 22 is roughly positioned on the B-pillar 13B, where it is to be positioned, while maintaining a somewhat straight shape. In this state, the fixing member 70 provided on the second portion 22 is spaced apart from the B-pillar 13B. When the fixing member 70 is moved toward fixing to the B-pillar 13B, the second portion 22 bends, as shown by the solid lines in Figure 7, and the fixing member 70 is fixed to the B-pillar 13B, thereby maintaining the second portion 22 in a bent state. As a result, the second portion 22 is positioned in a curved shape along the curved B-pillar 13B.

[0048] The location where second part 22 is arranged may be a cylindrical member made of metal or the like that has high rigidity and extends while curving, and second part 22 may be arranged to pass through the interior of the cylindrical member. In this case, second part 22 slides along the inner surface of the cylindrical member when passing through the interior of the cylindrical member. At this time, second part 22 bends due to the force from the inner surface of the cylindrical member, and is positioned inside the cylindrical member as it is, thereby being arranged in a curved shape along the curving cylindrical member.

[0049] The third region 23 includes a portion that is bent. The third region 23 bends more than the second region 22. The third region 23 has flexibility. The third region 23 is disposed so as to follow the wheelhouse 16 (a portion with a smaller radius of curvature) that curves more tightly than the pillar 13.

[0050] FIG. 8 is a diagram showing the wiring module 20 in a folded state.

[0051] The wiring module 20 is folded by being bent at the third region 23. At this time, the wiring module 20 may be folded so that the first region 21 and the second region 22 extend parallel to each other and overlap each other, as shown in Fig. 8. In the wiring module 20, an end of the wiring member 30 may be temporarily fixed to the first region 21 with adhesive tape 60 or the like.

[0052] The folded wiring module 20 is transported while being gripped at the first portion 21, thereby preventing the portion extending from the gripped position from sagging. In the wiring member 30, the section from the connector 32A at the front of the vehicle 10 to the branching portion below the B-pillar 13B is the section that has the greatest number of linear transmission members 31 and is the heaviest. In this embodiment, the first rigid member 40 is provided in this section. As a result, when this section is gripped while the wiring module 20 is in a folded state, the first rigid member 40 supports this section, making it easier to grip the wiring module 20.

[0053] The folded wiring module 20 is carried onto the floor 11 inside the vehicle 10 through the side openings 14A, 14B or the rear opening 15. The folded wiring module 20 is unfolded on the floor 11, and each portion is arranged along a predetermined path. At this time, the first portion 21 and the second portion 22 can be unfolded while maintaining a linear shape, which facilitates unfolding.

[0054] <Effects, etc.> According to the wiring module 20 configured as described above, by folding the third region 23 at a portion located between the first section 33 and the second section 34, the wiring module 20 can be folded so that the first region 21 and the second region 22, each provided with a rigid member, overlap. Because the first region 21 is more difficult to bend than the second region 22 and the third region 23, the folded wiring module 20 is carried in while being held at the first region 21, making the wiring module 20 less likely to bend and facilitating carrying. When the second region 22 is unfolded with the first region 21 of the folded wiring module 20 in a predetermined position after carrying, the second region 22 is provided with the second rigid member 50, which facilitates unfolding. Furthermore, because the second region 22 is more bendable than the first region 21, a portion of the unfolded second region 22 that deviates from the predetermined path can be easily deformed to follow the predetermined path. These features facilitate carrying in the wiring module 20 and arranging it along the predetermined path.

[0055] Furthermore, the first section 33 has a section that is arranged on the floor 11 of the vehicle 10, the second section 34 has a section that is arranged along the pillar 13 of the vehicle 10, and the third section 35 has a section that is arranged along the wheelhouse 16 of the vehicle 10. This makes it easy to carry in the wiring module 20 that is arranged on the floor 11 of the vehicle 10 and in the section adjacent to the floor 11 and arrange it along a predetermined route.

[0056] The second rigid member 50 is a resin sheet material 50. This allows the second rigid member 50 to be easily formed.

[0057] Furthermore, the wiring member 30 includes a plurality of linear transmission members 31, the third portion 23 includes an adhesive tape 60 that binds the plurality of linear transmission members 31, and the second rigid member 50 has higher rigidity than the adhesive tape 60. As a result, the third section 35 of the wiring member 30 is protected by the adhesive tape 60. Furthermore, the second section 34 of the wiring member 30 is protected by the second rigid member 50, which has higher rigidity than the adhesive tape 60.

[0058] [Embodiment 2] A wiring module according to a second embodiment will be described. Fig. 9 is a plan view showing a wiring module 120 according to the second embodiment. Fig. 10 is a cross-sectional view taken along line XX in Fig. 9. Fig. 11 is a diagram showing the wiring module 120 folded up. In the following description, components similar to those described so far are designated by the same reference numerals, and description thereof will be omitted.

[0059] The wiring module 120 of this embodiment differs from the above-described wiring module 20 in that it includes a silencer 140 instead of the protector 40. The silencer 140 covers the floor 11 of the vehicle 10. In the wiring module 120 of this embodiment, a part of the silencer 140 is configured as a first rigid member 141. The silencer 140 may be a member having countless fibers. The silencer 140 may be nonwoven fabric, felt, or the like. The silencer 140 may be foamed resin, or the like.

[0060] The silencer 140 includes a wiring arrangement portion 141 and a main body portion 144. The wiring arrangement portion 141 is a portion where the first section 33 is arranged and becomes the first rigid member 141. The main body portion 144 is a portion that is continuous with the wiring arrangement portion 141 and is more flexible than the wiring arrangement portion 141. The wiring arrangement portion 141 and the main body portion 144 may be formed from the same material. The rigidity of the wiring arrangement portion 141 may be made higher than the rigidity of the main body portion 144 by, for example, heat-pressing a portion of a base material having uniform rigidity. Furthermore, the base material may have portions with different thicknesses, and the rigidity of the thicker portions may be made higher than the rigidity of the thinner portions.

[0061] The wiring arrangement portion 141 in this embodiment has two clamping pieces 142, 143 that clamp the wiring member 30 from above and below. The upper clamping piece 142 is formed by folding back a portion that extends outward in the left-right direction of the vehicle 10 more than the lower clamping piece 143. Note that the silencer 140 may be arranged so that the clamping piece 142 is located below the clamping piece 143. The two clamping pieces 142, 143 are fixed by a fixing member 70. In the width direction of the vehicle 10, the wiring member 30 is located outside the fixing member 70, and the connecting portion of the two clamping pieces 142, 143 is located outside the wiring member 30.

[0062] Here, the fixing member 70 is a clamp including a base 71, a shaft 72, and a locking portion 73. However, the fixing member 70 is not limited to a clamp as long as it can secure the two clamping pieces 142, 143. For example, the fixing member 70 may be an adhesive, a rivet, or a tag pin-like member. The shaft 72 connects the base 71 and the locking portion 73. The shaft 72 penetrates the two clamping pieces 142, 143. The base 71 is located above the clamping piece 142 and is hooked onto the clamping piece 142. The locking portion 73 is located below the clamping piece 143 and is hooked onto the clamping piece 143. When the silencer 140 of the wiring module 120 is placed on the floor 11, the locking portion 73 may be locked to the floor 11. In other words, the fixing member 70 may also serve as a vehicle fixing member. The fixing member 70 does not have to be fixed to the vehicle 10. The vehicle fixing member may or may not be provided separately from the fixing member 70.

[0063] A surface of the wiring arrangement portion 141 that comes into contact with the wiring member 30 may be provided with a plurality of grooves. The plurality of grooves are provided at intervals along the path of the wiring member 30. Each of the plurality of grooves extends in a direction intersecting the extension direction of the wiring member 30. A convex portion is formed between two grooves, and the convex portion can function as an anti-slip portion for the wiring member 30.

[0064] Before being attached to the vehicle 10, the silencer 140 can be folded along fold lines 146 provided on the main body portion 144. By folding the wiring module 120 at the third region 23, the second region 22 located outside the silencer 140 can be wrapped in the folded silencer 140. Specifically, first, the second region 22 located outside the silencer 140 is folded at the third region 23 between the first region 21 and the second region 22 and positioned on the silencer 140. In this state, the wiring member 30 is further folded at the third region 23 between the two first regions 21 on the silencer 140, and the silencer 140 is folded at the fold lines 146, so that the second region 22 is wrapped in the folded silencer 140. Similarly, here, the third portion 23, the first portion 21C, and portions further to the rear that are located outside the silencer 140 can also be wrapped in the folded silencer 140. The size of the silencer 140 before folding is such that it cannot pass through the side openings 14A and 14B, and the size of the silencer 140 after folding is such that it can pass through the side openings 14A and 14B. Therefore, the wiring module 120 before folding has a size that does not allow it to pass through the side openings 14A and 14B, and the folded wiring module 120 has a size that allows it to pass through the side openings 14A and 14B.

[0065] The fold 146 is provided in the middle along the longitudinal direction of the vehicle 10, extending in the left-right direction of the vehicle 10, with the third portion 23 provided at the position of the fold 146 and the first portion 21 provided on each of the front and rear sides of the vehicle 10, sandwiching the fold 146. A groove may be provided in the fold 146 area. The groove extends along the fold 146. By providing a groove in the fold 146 area, the fold 146 becomes easier to identify. Furthermore, the silencer 140 can be easily folded at the fold 146.

[0066] In the wiring module 120 of this embodiment, the wiring member 30 disposed on the left side of the vehicle 10 and the wiring member 30 disposed on the right side are integrated via the silencer 140.

[0067] With this wiring module 120, the same effects as those of the wiring module 20 of the first embodiment can be obtained.

[0068] The wiring module 120 also includes a silencer 140 that covers the floor 11 of the vehicle 10, and the silencer 140 includes a wiring arrangement portion 141 in which the first section 33 is arranged and which becomes the first rigid member 141, and a main body portion 144 that is continuous with the wiring arrangement portion 141 and is more flexible than the wiring arrangement portion 141. This makes it possible to integrate the silencer 140 and the wiring member 30, while imparting rigidity to the first section 33 with the silencer 140.

[0069] Furthermore, before being attached to the vehicle 10, the silencer 140 is foldable along folds 146 provided on the main body portion 144, and by folding the wiring module 120 at the third portion 23, the second portion 22 located on the outside of the silencer 140 can be wrapped in the folded silencer 140. Because the silencer 140 is foldable, the wiring module 120 can be made compact, and the wiring module 120 can be easily inserted into the vehicle 10 through the side openings 14A and 14B for the side doors or the rear opening 15 of the vehicle 10. Furthermore, because the portion located on the outside of the silencer 140 can be folded at the third portion 23 and wrapped in the folded silencer 140, sagging and getting caught on the wiring member 30 are suppressed when the wiring module 120 is transported, and transportation of the wiring module 120 becomes easier.

[0070] Furthermore, the fold 146 is provided in the middle along the front-rear direction of the vehicle 10 so as to extend in the left-right direction of the vehicle 10, with the third portion 23 provided at the position of the fold 146 and the first portion 21 provided on each of the front and rear sides of the vehicle 10, sandwiching the fold 146. This makes it easy to carry the silencer 140 through the side openings 14A, 14B for the side doors of the vehicle 10 so that the left-right direction of the silencer 140 coincides with the left-right direction of the vehicle 10. This makes it easy to position the carried-in silencer 140 on the floor 11.

[0071] [Modification of the second embodiment] Fig. 12 is a plan view showing a modified example of the wiring module 120 according to embodiment 2. Fig. 13 is a cross-sectional view taken along line XIII-XIII in Fig. 12.

[0072] 12, the direction of the fold 246 of the silencer 240 differs from the direction of the fold 146 of the silencer 140 in the above-described wiring module 120. Specifically, the fold 246 is provided in the middle along the left-right direction of the vehicle 10 so as to extend in the front-rear direction of the vehicle 10. This makes it easy to provide the first section 21 continuously and without interruption from the front end to the rear end of the silencer 240 in the front-rear direction of the vehicle 10.

[0073] Similar to the wiring arrangement portion 141, the wiring module 220's first rigid member, the wiring arrangement portion 241, also has two clamping pieces 242, 243 that sandwich the wiring member 30 from above and below. In the wiring module 220, the arrangement of the two clamping pieces 242, 243 differs from the arrangement of the two clamping pieces 142, 143 in the wiring module 120. Specifically, the upper clamping piece 242 is formed by folding back a portion of the silencer 240 that is positioned more inward in the left-right direction of the vehicle 10 than the lower clamping piece 243. A long hole 245 that is long in the front-rear direction of the vehicle 10 remains in the portion of the silencer 240 that remains after the upper clamping piece 242 is folded back. A seat slide rail 17 may be disposed in the long hole 245. The two clamping pieces 242, 243 are also fixed by the fixing member 70. In the width direction of the vehicle 10, the wiring member 30 is located outside the connecting portion of the two clamping pieces 242, 243, and the fixing member 70 is located outside the wiring member 30. A plurality of fixing members 70 are provided at intervals in the front-rear direction of the vehicle 10. A portion of the wiring member 30 that branches off from a portion along the floor 11 and faces the B-pillar 13B extends outward from between the plurality of fixing members 70 toward the outside of the silencer 240. Note that the silencer 240 may be arranged so that the clamping piece 242 is located lower than the clamping piece 243.

[0074] [Note] Up to now, it has been described that the first section 33 has a section disposed on the floor 11 of the vehicle 10, the second section 34 has a section disposed along the pillar 13 of the vehicle 10, and the third section 35 has a section disposed along the wheelhouse 16 of the vehicle 10, but this is not a required configuration. The wiring member 30 may be disposed in a location on the vehicle 10 other than the floor 11 or its vicinity.

[0075] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually contradictory. [Explanation of symbols]
