[0018] [Description of Embodiments of the Present Disclosure]

[0019] First, embodiments of the present disclosure are listed for description.

[0020] The wiring module for a vehicle door and the method for manufacturing the wiring module for a vehicle door of the present disclosure are as follows.

[0021] (1) A wiring module for a vehicle door, comprising: a surface component for a vehicle door, which is assembled to a door panel of a vehicle; a wiring component, which is arranged on a main surface of the surface component for the vehicle door; and a retaining component, which is formed to cover the main surface of the surface component for the vehicle door and the wiring component and is directly bonded to at least the main surface of the surface component for the vehicle door, and retains the wiring component in a state of being arranged on the main surface of the surface component for the vehicle door.

[0022] The wiring component can be attached to the planar member for a vehicle door by means of the holding member directly joined to the planar member for a vehicle door. A new technique for attaching the wiring component for a vehicle door to the planar member for a vehicle door can be provided.

[0023] Here, the planar member for a vehicle door is a planar member whose dimension in the thickness direction is smaller than its dimension in the surface direction.

[0024] (2) Preferably, the wiring member is accommodated in a holding groove formed on the main surface of the door planar member. This is because the wiring member can be prevented from falling out of the holding groove by the holding member.

[0025] (3) Preferably, the wiring component includes a plurality of electric wires, and the retaining grooves are formed in parallel on the door surface component, and the electric wires are received one by one in the retaining grooves. This is because the electric wires can be retained in parallel. In addition, this is because the retaining component can be made thinner.

[0026] (4) Preferably, the door planar member includes a wall portion that partitions a region where the holding member is provided, and the outer edge of the holding member is in contact with the wall portion. This is because it is possible to suppress leakage of resin when the holding member is formed by injecting resin.

[0027] (5) Preferably, the holding member is made of a foamed resin and also serves as a sound insulator. This is because it is not necessary to separately provide a member for fixing the wiring member and a sound insulator.

[0028] (6) Preferably, the holding member entirely covers at least a portion of the main surface where the wiring member is disposed, because the wiring member disposed on the main surface can be held over the entire length.

[0029] (7) In addition, the manufacturing method of the wiring module for a vehicle door disclosed in the present invention comprises the following steps: step (a) of arranging the wiring component on the main surface of the surface component for a vehicle door assembled to the vehicle door panel; and step (b) of injecting a softened resin material onto the main surface of the surface component for the vehicle door and the wiring component after the above step (a) and making the resin material directly bonded to at least the above main surface. The wiring component can be mounted on the surface component for the vehicle door by directly bonding the injected resin to the surface component for the vehicle door. A new technology for mounting the wiring component for the vehicle door on the surface component for the vehicle door can be provided.

[0030] [Details of the embodiments of the present disclosure]

[0031] Hereinafter, a specific example of the wiring module for a vehicle door and a method for manufacturing the same will be described with reference to the drawings. The present invention is not limited to these examples but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0032] [Implementation Method]

[0033] Hereinafter, a wiring module for a vehicle door and a method for manufacturing the same according to an embodiment will be described. Figure 1 It is a schematic side view showing the vehicle door 10 in which the vehicle door wiring module 20 according to the embodiment is assembled. Figure 2 It is along Figure 1 A cross-sectional view taken along line II-II. Figure 3 It is along Figure 1 A cross-sectional view taken along line III-III. Figure 4 It is a schematic perspective view showing a portion of the wiring member 40 extending outward from the door planar member 22 . Figure 5 It is a schematic perspective view showing a portion of the wiring member 40 extending outward from the door planar member 22 . Figure 6 2 is an explanatory diagram showing a method for manufacturing a wiring module 20 for a vehicle door according to an embodiment. Figure 1 In FIG. 1 , the holding member 50 covering the wiring member 40 is indicated by a two-dot chain line.

[0034] The vehicle door 10 is formed in a flat shape as a whole, and is a part of the vehicle that is opened and closed in a manner that can separate the interior of the vehicle from the exterior of the vehicle. The vehicle door 10 is assumed to be a driver's seat side door, a passenger seat side door, a rear seat door, etc. The vehicle door 10 includes a door panel 12 and a door wiring module 20.

[0035] The door panel 12 includes an outer panel (not shown) and an inner panel 14. The outer panel is provided at the portion of the door 10 facing the outside of the vehicle, and is the portion that constitutes the appearance of the vehicle together with the vehicle body. The inner panel 14 is provided at the vehicle compartment side of the outer panel. Between the inner panel 14 and the outer panel, a space for storing windows and the like is usually formed. Windows that are exposed to the rainwater environment are accommodated in this space, and a slit-shaped opening is formed above the space for the windows to enter and exit. Therefore, this space is a space that water may invade. In addition, this space is a space that may be connected to the outside space, and therefore, it is also a space that wind noise from the outside may invade. On the other hand, an opening 15 for accessing the above-mentioned space when the door 10 is manufactured or maintained is provided on the inner panel 14. Preferably, the opening 15 is blocked during normal use of the vehicle and the like. Here, a wiring module 20 for the door is installed in a manner that blocks the opening 15.

[0036] The door wiring module 20 includes a door planar member 22, a wiring member 40, and a holding member 50. The wiring member 40 is held by the door planar member 22 by the holding member 50. Therefore, by assembling the door planar member 22 to the door 10, the wiring member 40 is also assembled to the door 10.

[0037] In this example, the surface member 22 for the vehicle door is a member that is assembled between the door panel 12 and the design decoration part (not shown) in the vehicle door 10. The surface member 22 for the vehicle door is not particularly limited as long as it is assembled between the door panel 12 and the design decoration part in the vehicle door 10, and various surface members can be used. The following describes the case where the surface member 22 for the vehicle door is an interior decoration.

[0038] The vehicle door 10 of this example also includes a design portion. The design portion is a portion of the vehicle door 10 that faces the inner side of the vehicle interior and constitutes the interior appearance of the vehicle. For example, a door handle, an operating unit for vehicle-mounted equipment, etc. are mounted on the design portion.

[0039] The door surface member 22 is provided as a member for more completely separating the cabin space from the outside space together with the inner panel 14. The door surface member 22 is a surface member. In addition, the surface member mentioned here refers to a member that is expanded in two dimensions and has a thickness dimension that is smaller than the dimension in the surface direction (two directions orthogonal to the thickness direction), and does not necessarily need to be flat in the front-back direction (thickness direction), and may also have concave and convex in the front-back direction.

[0040] The door surface member 22 includes a main plate portion 24 and a storage space forming portion 28. The door surface member 22 is assembled to the inner panel 14 by screw fastening, a locking structure, etc., in a state where it is located at a predetermined position to block the opening 15 of the inner panel 14.

[0041] The main board portion 24 is a portion that is expanded in a plate shape to a size that can block the opening 15. In addition, a speaker assembly hole 25 for assembling a speaker is formed on the main board portion 24. It is not necessary to form the speaker assembly hole 25 on the door surface member 22. For example, it is also possible to form a structure in which the speaker assembly hole is formed on the inner plate 14, and the door surface member 22 is assembled to the inner plate 14 in an area other than the portion where the speaker is assembled. The storage space forming portion 28 is formed in a container shape that opens to one main surface side (vehicle compartment side) of the main board portion 24 and protrudes to the other main surface side (outside) of the main board portion 24. The storage space forming portion 28 is formed in a container shape that is smaller than the opening 15. In a state where the door surface member 22 is embedded in the opening 15 of the inner plate 14, the storage space forming portion 28 is arranged on the inner side of the opening 15. In addition, the opening edge of the storage space forming portion 28 and the peripheral edge of the opening 15 are blocked by the main board portion 24. For example, if the portion of the peripheral edge of the main plate portion 24 that overlaps with the inner plate 14 is fastened to the inner plate 14 by screws or the like, the gap therebetween can be closed as much as possible.

[0042] A part or all of the electric components 16, 17, 18 can be assembled in the storage space forming portion 28 of the door surface member 22, and the electric components 16, 17, 18 are assembled to the door 10. Here, the electric components 17, 18 are assembled. As the electric components 17, 18, a motor for opening and closing a window, an actuator for locking and unlocking the door 10, various switches, etc. can be envisioned.

[0043] The planar member 22 for a vehicle door has a retaining groove 30 formed on its main surface for accommodating the wiring member 40. The retaining groove 30 retains at least a portion of the wiring member 40 along the extension direction. By accommodating and retaining the wiring member 40 in the retaining groove 30, the wiring member 40 is wired and retained in the planar member 22 for a vehicle door. The retaining groove 30 is formed corresponding to the wiring form of the wiring member 40. Here, the retaining groove 30 is formed on both the main board portion 24 and the accommodating space forming portion 28, but it can be formed only on the main board portion 24, or it can be formed only on the accommodating space forming portion 28. The retaining groove 30 is formed to be the same as the wires 41, 42, 43 or larger than the wires 41, 42, 43. Therefore, the entire periphery of the wires 41, 42, 43 is accommodated in the retaining groove 30. However, the retaining groove 30 can also be formed to be smaller than the wires 41, 42, 43. In this case, parts of the electric wires 41 , 42 , and 43 may protrude from the opening of the holding groove 30 .

[0044] The surface component 22 for the vehicle door has a good rigidity that is not easy to bend in the front and back directions. Therefore, when the surface component 22 for the vehicle door is assembled to the vehicle door panel 12, it is easy to maintain the expanded shape because the edge and the like are not easy to bend, so that the assembly becomes easy. For example, the surface component 22 for the vehicle door is formed with higher rigidity than the retaining component 50. The surface component 22 for the vehicle door is a component molded by a mold using, for example, resin or metal as a material. The surface component 22 for the vehicle door can be a structure formed by pouring molten material into a mold, or a structure formed by stamping a plate using a mold.

[0045] The wiring component 40 is provided in the vehicle door 10, and is an electric wiring connected to the electrical components 16, 17, 18 assembled in the vehicle door 10. The wiring component 40 of the vehicle door 10 is usually connected to the vehicle at the hinge side of the vehicle door 10, and branches when going from the front side to the rear side of the vehicle door 10 to be connected to various electrical components 16, 17, 18. Here, the wiring component 40 includes a plurality of electric wires 41, 42, 43. As the electric wires 41, 42, 43, covered electric wires in which a coating is formed around a core wire composed of a conductor can be used. The core wire can be a single core wire or a stranded wire.

[0046] Here, a plurality of electric wires 41, 42, 43 are assembled in parallel at one end of each. It is assumed that one end of the plurality of electric wires 41, 42, 43 extends from the hinge side of the door 10 from the door 10 in a bundled state, is introduced into the vehicle body, and is connected to other connectors in the vehicle body via a common connector or the like. The electric wire 41 extends longest relative to the electric wires 42, 43, and the electric wires 42, 43 are branched in the middle of the extension direction of the electric wire 41. Connectors 44, 45, 46 are installed at the other end of each of the electric wires 41, 42, 43. The electric wires 41, 42, 43 are connected to the electrical components 16, 17, 18 via the connectors 44, 45, 46.

[0047] The electric wires 41, 42, 43 are individually held in the plurality of holding grooves 30. Here, the plurality of holding grooves 30 are formed in parallel in a number corresponding to the plurality of electric wires 41, 42, 43. As the electric wires 41, 42, 43 branch, the holding grooves 30 also branch.

[0048] More specifically, the electric wire 41 is held along a constant path from the middle part of the front edge of the main board portion 24 in the vertical direction, through the main surface of the front side of the main board portion 24, the main surface of the bottom of the storage space forming portion 28, and the main surface of the rear side of the main board portion 24, to the middle part of the rear edge of the main board portion 24 in the vertical direction. The electric wire 42 is held on the upper side of the electric wire 41, along a constant path from the middle part of the front edge of the main board portion 24 in the vertical direction, through the main surface of the front side of the main board portion 24, to the main surface of the bottom of the storage space forming portion 28. The electric wire 43 is held on the lower side of the electric wire 41, along a constant path from the middle part of the front edge of the main board portion 24 in the vertical direction, through the main surface of the front side of the main board portion 24, to the main surface of the bottom of the storage space forming portion 28.

[0049] The electric wire 41 extends from the rear end of the door surface member 22 and is connected to the electric component 16. The electric component 16 is a component assembled to the rear of the door 10, and can be, for example, a motor for locking and unlocking the door. The electric wires 42 and 43 branch from the electric wire 41 in the storage space forming portion 28, and are connected to the electric components 17 and 18 in the storage space forming portion 28. In addition, the electric wire 42 and the electric wire 43 branch at the same position in the middle portion of the extension direction of the electric wire 41, but can also branch at different positions.

[0050] In the present embodiment, the plurality of electric wires 41, 42, 43 are individually accommodated in the holding groove 30, but the plurality of electric wires 41, 42, 43 may all be accommodated in a common holding groove and held. In addition, the plurality of electric wires 41, 42, 43 may be divided into a plurality of groups, and a number of holding grooves corresponding to the plurality of groups may be formed, and the plurality of electric wires 41, 42, 43 may be accommodated in a plurality of holding grooves for each of the plurality of groups and held.

[0051] The holding member 50 is a member that holds the wiring member 40 in a state of being arranged on the main surface of the door surface member 22. The holding member 50 is formed to cover the main surface of the door surface member 22 and the wiring member 40 and is directly bonded to at least the main surface of the door surface member 22. Here, the state of direct bonding refers to a state of direct close contact without an intervening object such as an adhesive. The holding member 50 may or may not be in contact with the wires 41, 42, 43. Alternatively, the holding member 50 may be directly bonded to the wires 41, 42, 43 at the portion where the holding member 50 contacts the wires 41, 42, 43.

[0052] The holding member 50 is directly bonded to the entire portion of the door surface member 22 that is in contact with the door surface member 22. The holding member 50 is formed of a foamed resin such as polyurethane foam as a material. Alternatively, the holding member 50 may be formed of a resin other than a foamed resin (referred to as a non-foamed resin) as a material. The holding member 50 may be a single layer or multiple layers formed of the same material.

[0053] The retaining member 50 also serves as a soundproofing member. A soundproofing member is a member that reduces sound. The soundproofing member may be a structure that functions as a sound absorbing member or a structure that functions as a sound insulating member. The sound absorbing member has a space when observing the cross section in the thickness direction. The sound absorbing member reduces the reflection of sound as much as possible by, for example, absorbing incident sound energy. For example, by forming the retaining member 50 with a foaming resin such as polyurethane foam as a material, the retaining member 50 can also serve as a sound absorbing member. The sound insulating member does not have a space when observing the cross section in the thickness direction. The sound insulating member, for example, isolates sound as much as possible by absorbing or reflecting sound energy. For example, by forming the retaining member 50 with a resin such as a resin that is not a foaming resin (referred to as a non-foaming resin) as a material, the retaining member 50 can also serve as a sound insulating member. The retaining member 50 is formed into a double-layer structure with a layer made of a foaming resin and a layer made of a non-foaming resin, and has both the function of a sound absorbing member and the function of a sound insulating member.

[0054] The holding member 50 covers the entire surface of at least the portion of the main surface of the door planar member 22 where the wiring member 40 is disposed. The entire surface mentioned here means covering the entire portion of at least the middle portion of the main surface of the door planar member 22 where the wiring member 40 is disposed. Figure 1 In the example shown, the holding member 50 covers the entire portion of at least the portion of the main surface of the door planar member 22 where the wiring member 40 is arranged, except for the end of the wiring member 40 and the portion of the wiring member 40 located at the edge of the door planar member 22. However, as long as the holding member 50 can hold the wiring member 40, the area covering the wiring member 40 may be appropriately set, and may be a portion.

[0055] The holding member 50 is provided in the storage space forming portion 28 of the surface member 22 for a vehicle door. The surface member 22 for a vehicle door includes a wall portion 29 that partitions the area where the holding member 50 is provided. Here, a portion of the inner surface that constitutes the storage space forming portion 28 in the surface member 22 for a vehicle door becomes the wall portion 29 that partitions the area where the holding member 50 is provided. At least a portion of the outer edge of the holding member 50 is in contact with the wall portion 29. At least a portion of the peripheral portion of the holding member 50 extends along the wall portion 29. However, the wall portion 29 may not be formed in the surface member 22 for a vehicle door. In addition, the outer edge portion of the holding member 50 may not reach the wall portion 29.

[0056] The electrical component 17 assembled on the surface member 22 for a vehicle door is covered by the retaining member 50. The electrical components 17 and 18 assembled on the surface member 22 for a vehicle door in this way may also be the electrical components 17 covered by the retaining member 50. For example, the electrical component 17 connected to the electric wire 42 before the retaining member 50 is formed may also be covered by the retaining member 50. The electrical component 18 assembled on the surface member 22 for a vehicle door may not be covered by the retaining member 50. The electrical components 17 and 18 assembled on the surface member 22 for a vehicle door in this way may also be the electrical components 18 not covered by the retaining member 50. For example, the electrical component 18 connected to the electric wire 43 after the retaining member 50 is formed may not be covered by the retaining member 50. Of course, the electrical component connected to the electric wire before the retaining member is formed may not be covered by the retaining member. When there is an electric component 18 not covered by the holding member 50 among the electric components assembled on the door surface member 22, the electric component 18 not covered by the holding member 50 can be separated by a mold or the like in a manner that prevents the surrounding from entering the resin when the holding member 50 is formed, so that it can be made not covered by the holding member 50. The electric components assembled on the door surface member 22 may all be covered by the holding member 50, or may not be covered by the holding member 50, or the electric components covered by the holding member 50 and the electric components not covered by the holding member 50 may coexist.

[0057] Here, the holding member 50 is formed to block the opening of the holding groove 30 on the side opposite to the bottom thereof, thereby preventing the electric wires 41, 42, 43 in the holding groove 30 from falling out. In addition, the holding member 50 may enter the holding groove 30 or may not enter the holding groove 30. When the holding member 50 enters the holding groove 30, it may fill the entire holding groove from the opening to the bottom of the holding groove 30, or may fill only a portion of the opening side. When the holding member 50 fills only a portion of the opening side, it may reach the electric wires 41, 42, 43 or may not reach the electric wires 41, 42, 43.

[0058] The holding member 50 may also hold the portion of the electric wires 41, 42, 43 that is not accommodated in the holding groove 30. When the holding member 50 holds the electric wires 41, 42, 43 located on the flat surface of the door surface member 22, in the portion of the holding member 50 that is directly bonded to the door surface member 22, the thickness of the layer of the holding member 50 that is directly bonded to the door surface member 22 is preferably greater than the thickness of the electric wires 41, 42, 43.

[0059] At the outer edge of the retaining member 50, there are electric wires 41, 42, 43 extending from the retaining member 50. One end of the electric wires 41, 42, 43 is a portion extending toward the door hinge. One end of the electric wires 41, 42, 43 extends outward from the front edge of the door surface member 22. The other end of the electric wire 41 is connected to the electrical component 16 of the door surface member 22 that is not provided on the door 10. The other end of the electric wire 41 extends outward from the rear edge of the door surface member 22. The other end of the electric wire 43 extends from the retaining member 50 inside the wall portion 29. For example, the other end of the electric wire 43 is connected to the electrical component 18 after the retaining member 50 is formed, and therefore, the other end of the electric wire 43 extends from the retaining member 50.

[0060] The thickness dimension of the holding member 50 is not particularly limited as long as it can hold the wiring member 40. When the holding member 50 also serves as a sound insulator, the sound insulation performance is improved if the thickness dimension of the holding member 50 is large. Figure 2 In the example shown, the thickness dimension of the holding member 50 is the same as the depth dimension of the receiving space forming portion 28 (the height dimension of the wall portion 29). Of course, the thickness dimension of the holding member 50 may be smaller than the depth dimension of the receiving space forming portion 28 (the height dimension of the wall portion 29), or may be larger than the depth dimension of the receiving space forming portion 28. The holding member 50 may also be formed to be the same as or not to protrude more than the portion protruding most outwardly in the main surface of the door planar member 22. This is because the thickness dimension of the door wiring module 20 can be suppressed from increasing.

[0061] Alternatively, when there is a portion extending from the storage space forming portion 28 to the main board portion 24, such as one end of the electric wires 41, 42, 43 and the other end of the electric wire 41, an inclined surface gently inclined from the main surface of the bottom of the storage space forming portion 28 to the main surface of the main board portion 24 is formed, and the electric wire is arranged in this portion. In addition, in the portion of the main board portion 24 where the electric wires 41, 42, 43 extend outward, there may be an extension portion 26 that is recessed than the surrounding portion. The extension portion 26 may be covered by the holding member 50 or may not be covered by the holding member 50.

[0062] The portion of the electric wires 41, 42, 43 not held by the holding member 50 on the main surface of the door surface member 22 may be held by other holding portions or may not be held by other holding portions. Figure 3 In the example shown, the anti-detachment portion 32 is formed. The anti-detachment portion 32 is a portion formed to narrow the opening 15 or block the opening 15 to prevent the electric wires 41, 42, 43 from detaching from the opening 15. The anti-detachment portion 32 is a portion formed by, for example, crushing a protruding portion 33 formed so as to protrude to the side opposite to the bottom at the peripheral edge of the opening portion on the side opposite to the bottom in the holding groove 30. The protruding portion 33 is melted and crushed by heat, for example, by being pressed against the heating member 60.

[0063] <Manufacturing method>

[0064] A method for manufacturing the door wiring module 20 will be described. The method for manufacturing the door wiring module 20 includes the following steps (a) and (b).

[0065] Step (a) is a step of arranging a wiring component 40 on the main surface of the door surface component 22 assembled to the door panel 12 of the vehicle. As a result, the wiring component 40 is in a desired wiring state. Step (b) is a step of injecting softened resin material B onto the main surface of the door surface component 22 and the wiring component 40 after step (a), and directly bonding the resin material B to at least the main surface of the door surface component 22. In step (b), the resin material B solidifies in a state of being directly bonded to the main surface of the door surface component 22, thereby forming the above-mentioned retaining component 50, which retains the wiring component 40 on the main surface of the door surface component 22.

[0066] Regarding step (a), here, the wiring member 40 is arranged on the main surface of the main plate portion 24 and the storage space forming portion 28 of the door surface member 22. At this time, the wiring member 40 is arranged along the holding groove 30 formed in the door surface member 22. The wiring member 40 is held in the holding groove 30 to maintain a predetermined wiring state.

[0067] In step (b), the resin material B is injected from the injection port 70, for example, and then in a softened state, it contacts the main surface of the door surface member 22. The resin material B is a material that can be directly bonded to the main surface of the door surface member 22 by contacting the main surface of the door surface member 22 in a softened state. Here, by using a foamed resin as the resin material B, the holding member 50 can also serve as a soundproofing member.

[0068] When the resin material B is injected, the periphery of the injection area is partitioned by the wall portion 29, the mold, etc. In this way, it is possible to suppress the injection of the resin material B into the portion where the resin material B is not intended to be injected. The portion where the resin material B reaches the wall portion 29, the mold, etc. becomes the outer edge portion of the holding member 50. In the portion where the resin material B reaches the wall portion 29, it is directly bonded to the wall portion 29. In addition, in the case where the viscosity of the resin material B is high, the resin material B may not enter the holding groove 30. In addition, in the case where the viscosity of the resin material B is low, the resin material B may enter the holding groove 30.

[0069] When a predetermined amount of resin material B is injected, its surface portion (the surface on the side opposite to the side in contact with the main surface of the door surface member 22) may be smooth or not. If the resin material B is smooth, the surface portion of the holding member 50 can be made flat. In addition, there may be a mold covering the upper portion of the injection area separated by the wall portion 29, the mold, etc. In this case, the surface portion of the holding member 50 is formed into a shape corresponding to the shape of the inner surface of the covering mold.

[0070] According to the present disclosure, the wiring member 40 can be attached to the door planar member 22 via the holding member 50 directly joined to the door planar member 22. A new technique for attaching the wiring member 40 for the door 10 to the planar member for the door 10 can be provided.

[0071] A holding groove 30 for accommodating the electric wires 41, 42, 43 is formed, and the holding member 50 covers the holding groove 30, so that the wiring member 40 can be prevented from being detached from the groove by the holding member 50. Since a plurality of holding grooves 30 are formed, the electric wires 41, 42, 43 can be held in a parallel state. In addition, the electric wires 41, 42, 43 can be prevented from protruding from the holding groove 30, and the holding member 50 can be made thinner.

[0072] The door planar member 22 includes the wall portion 29 that partitions the region where the holding member 50 is provided. The outer edge of the holding member 50 is in contact with the wall portion 29 , so that leakage of the resin material B can be suppressed when the resin material B is injected to form the holding member 50 .

[0073] The holding member 50 is formed of a foamed resin and also serves as a sound insulator. Therefore, it is not necessary to separately provide a member for fixing the wiring member 40 and a sound insulator.

[0074] Since the holding member 50 entirely covers at least the portion of the main surface where the wiring member 40 is arranged, the holding member 50 can hold the wiring member 40 arranged on the main surface over the entire length.

[0075] [Note]

[0076] In the embodiment, the door surface member 22 of the door wiring module 20 is an example of an interior decoration, but this is not necessarily a structure. The door surface member of the door wiring module 20 can be a surface member assembled to the door 10, for example, it can also be a design decoration.

[0077] The holding groove 30 may not be formed in the door planar member 22. In this case, the electric wires 41, 42, 43 may be arranged in an overlapping manner on the door planar member 22, or may be arranged in a non-overlapping manner.

[0078] In addition, the respective configurations described in the above-mentioned embodiment and the respective modifications can be appropriately combined as long as they do not contradict each other.
