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

[0010] The routing structure of the additional wiring member of the present disclosure is as follows.

[0011] (1) An arrangement structure for an additional wiring member in an interior member facing the passenger compartment, comprising: an additional wiring member arranged on the interior member from the passenger compartment side; and an additional interior member covering the additional wiring member from the opposite side of the interior member, wherein the interior member has a joint between adjacent interior portions, and the additional interior member has a cover portion covering the additional wiring member and a retaining portion protruding from the cover portion, inserted into the joint, and held by the interior member.

[0012] According to the wiring structure for the additional wiring member of (1), the additional wiring member can be easily routed onto the interior member via the additional interior member, thereby making it easy to add wiring members to the vehicle.

[0013] (2) In the wiring structure for an additional wiring member of (1), the cover portion may be formed in a cylindrical shape to house the additional wiring member, and the holding portion may protrude outward from an outer surface of the cover portion. This makes it possible to easily add a wiring member to a vehicle by holding the additional interior member housing the additional wiring member in the interior member.

[0014] (3) In the wiring structure for the additional wiring member of (2), a slit may be formed in the cover portion along the extension direction, and the holding portion may protrude from the edge of the slit. This makes it easy to store the additional wiring member inside the cover portion through the slit. It also makes it easy to align the edge of the slit with the seam.

[0015] (4) In the wiring structure for the additional wiring member of (3), the retaining portion may have a first retaining portion protruding from a first edge of the slit and a second retaining portion protruding from a second edge of the slit, and the first retaining portion and the second retaining portion may be inserted into the joint, thereby preventing the slit from opening.

[0016] (5) In the wiring structure for an additional wiring member according to any one of (1) to (4), the additional interior member may have higher rigidity than the additional wiring member, which makes it easier to insert the holding portion into the joint.

[0017] (6) In the routing structure for an additional wiring member according to any one of (1) to (5), the additional wiring member and the additional interior member may extend along the joint. The joint portion of the interior member is originally a portion where a discontinuous design appears. By having the additional wiring member and the additional interior member extend along the joint, occupants are less likely to notice a sense of incongruity in the design due to the routing of the additional wiring member compared to a state in which the additional wiring member is not routed.

[0018] (7) In the wiring structure for the additional wiring member of (6), the joint may have a first joint and a second joint that are different from each other, the additional wiring member may have a first extending portion that extends along the first joint and a second extending portion that extends along the second joint, and the additional interior member may have a first additional interior member that holds the first extending portion at the first joint and a second additional interior member that holds the second extending portion at the second joint. This makes it easy to route the additional wiring member in the vehicle even if the same joint is not continuous from one end to the other end of the additional wiring member.

[0019] (8) In the wiring structure for an additional wiring member according to any one of (1) to (7), a shielding portion may be provided between the cover portion and the additional wiring member, thereby suppressing noise from the additional wiring member by the shielding inside the additional interior member.

[0020] [Details of the embodiments of the present disclosure] Specific examples of the wiring structure of the additional wiring member 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 following describes the wiring structure for an additional wiring member according to the first embodiment. Fig. 1 is a schematic plan view showing a part of a vehicle 10 in which a wiring structure 30 for an additional wiring member is incorporated. Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1. Fig. 4 is an explanatory diagram showing how an additional interior member 40 is inserted into a joint 16.

[0022] The vehicle 10 is, for example, an automobile. The vehicle 10 includes a passenger compartment 11 and an interior member 12 facing the passenger compartment 11. The routing structure 30 for an additional wiring member routes the additional wiring member 32 on a side closer to the interior compartment than the interior member 12. The routing structure 30 for an additional wiring member includes the additional wiring member 32 and an additional interior member 40. The additional wiring member 32 is arranged on the interior member 12 from the inside of the compartment. The additional wiring member 32 is arranged on the side closer to the interior compartment than the interior member 12. The additional interior member 40 covers the additional wiring member 32 from the side opposite the interior member 12. The interior member 12, to which the additional wiring member 32 is routed, will first be described.

[0023] The interior member 12 has an interior portion 13 facing the passenger compartment 11. The area inside the vehicle 10 relative to the interior portion 13 is the interior side, and the area outside the vehicle 10 relative to the interior portion 13 is the exterior side. An exterior member of the vehicle 10, such as a body panel, is usually located on the exterior side of the interior portion 13. The interior member 12 may be any member that has the interior portion 13. For example, the interior member 12 may be various trims such as a pillar trim 12A, a roof trim, or a door trim. Trims may be called garnishes, liners, or linings depending on the location. For example, pillar trims may be called pillar garnishes, and roof trims may be called roof linings. The interior member 12 may also be various panels such as an instrument panel 12B. For example, the interior member 12 may also be a center console, a floor carpet, or the like.

[0024] A vehicle 10 is provided with a plurality of interior portions 13 via one or more interior members 12. The plurality of interior portions 13 are portions that are molded separately from one another and then assembled after molding. The plurality of interior portions 13 are joined together so as to face different areas of the passenger compartment 11. The plurality of interior portions 13 may be provided separately in a plurality of different interior members 12. One interior member 12 may have a plurality of interior portions 13.

[0025] In the interior portion 13, the surface facing the vehicle interior 11 is the interior surface 14. The interior surface 14 may have any extent. The interior surface 14 may have a flat portion or a curved portion. The interior surface 14 may have a portion that extends in the front-rear direction and the vehicle width direction, a portion that extends in the front-rear direction and the vertical direction, or a portion that extends in the vehicle width direction and the vertical direction.

[0026] A seam 16 is provided between adjacent interior portions 13 among the multiple interior portions 13. The seam 16 is provided between the edge portions 15 of adjacent interior surfaces 14. The seam 16 may be provided between the outer edge portions of adjacent interior surfaces 14. In a portion where an opening of one interior surface 14 is closed by another interior surface 14, the seam 16 may be provided between the periphery of the opening of one interior surface 14 and the outer edge of the other interior surface 14. The additional wiring member 32 is added using the seam 16. Before the additional wiring member 32 and the additional interior member 40 are added, the seam 16 and the interior surface 14 are observable from inside the room. By adding the additional wiring member 32 and the additional interior member 40, the seam 16 and the interior surface 14 are partially or entirely covered by the additional wiring member 32 and the additional interior member 40, respectively.

[0027] Here, an example will be described in which the additional wiring member 32 is routed to the front side of the vehicle interior 11. Here, an example will be described in which the interior members 12 to which the additional wiring member 32 is routed are the front pillar trim 12A and the instrument panel 12B. The additional wiring member 32 may also be routed to the rear side or middle of the vehicle interior 11. The interior members 12 to which the additional wiring member 32 is routed may be other than the front pillar trim 12A and the instrument panel 12B.

[0028] The front pillar trim 12A is made of resin or the like. The front pillar trim 12A covers the A-pillar. The pillar is a part that supports the roof against the lower part of the vehicle body. Multiple pillars are provided in the longitudinal direction of the vehicle 10. The A-pillar is the frontmost pillar of the multiple pillars in the longitudinal direction of the vehicle 10. The side edges of the windshield (also called the windshield) extend in the height direction along the A-pillar. A pair of A-pillars and front pillar trims 12A are provided on the left and right. For example, the front pillar trim 12A has a pillar trim upper that runs along the A-pillar and a pillar trim lower 13A that is continuous with the lower end of the pillar trim upper. The pillar trim lower 13A may be longer in the longitudinal direction of the vehicle 10 than the pillar trim upper. The pillar trim lower 13A may protrude further toward the interior in the width direction of the vehicle 10 than the pillar trim upper. If the vehicle 10 is provided with a front quarter window (also called a triangular window), the A-pillar and the pillar trim upper may be divided in the front-rear direction, with the front quarter window disposed therebetween. In this case, the pillar trim lower 13A may connect the divided pillar trim upper in the front-rear direction.

[0029] The instrument panel 12B is formed from resin or the like. The instrument panel 12B is located in front of the driver's seat and passenger seat. Instruments such as a speedometer are incorporated into the instrument panel 12B. The instrument panel 12B has an upper instrument panel 13B and a lower instrument panel 13C. The upper instrument panel 13B faces upward. The upper instrument panel 13B is located between a pair of pillar trim lowers 13A. The lower instrument panel 13C faces rearward. The lower instrument panel 13C is connected to the rear edge of the upper instrument panel 13B. A center cluster, a meter cluster, etc. may be provided in a portion of the upper instrument panel 13B or the lower instrument panel 13C.

[0030] In the vehicle 10, a steering wheel 18 is provided facing rearward from the instrument panel 12B. A reinforcement 20 is provided inside the instrument panel 12B. The reinforcement 20 is an elongated member made of metal or the like. The reinforcement 20 extends in the vehicle width direction and connects the side panels of the vehicle body together.

[0031] The additional wiring member 32 is a wiring member 22 that connects electrical components mounted on the vehicle 10. The additional wiring member 32 includes, for example, at least one electric wire 33. The electric wire 33 has a core wire and a covering surrounding the core wire. The electric wire 33 may be formed by twisting a plurality of electric wires 33 together. The electric wire 33 may have a shielding layer on its outer periphery. The additional wiring member 32 may include at least one of a signal line and a power line. In addition to or instead of the electric wire 33 having a core wire covered with a covering, the additional wiring member 32 may include another wiring member, for example, an FPC (Flexible Printed Circuits) in which a circuit made of metal foil is formed on a resin film.

[0032] The positions of the connection destinations of both ends of the additional wiring member 32 are not particularly limited and can be set as appropriate. One end of the additional wiring member 32 may be connected to an additional electrical component, and the other end of the additional wiring member 32 may be connected to an existing electrical component. The existing electrical component supplies power to the additional electrical component or incorporates the additional electrical component into an existing in-vehicle network via the additional wiring member 32. One end and the other end of the additional wiring member 32 may be connected to different additional electrical components. In this case, it is preferable that wiring members for supplying power to the additional electrical component or incorporating the additional electrical component into the existing in-vehicle network are provided separately from the additional wiring member 32. Here, it is described that one end of the additional wiring member 32 is connected to an additional electrical component arranged on the roof, and the other end of the additional wiring member 32 is connected to an existing electrical component arranged outside the vehicle cabin relative to the instrument panel 12B. The existing electrical component may be, for example, an ECU (electronic control unit).

[0033] 1 omits one end and the other end of the additional wiring member 32. One end of the additional wiring member 32 is guided, for example, along a pillar to the roof. The other end of the additional wiring member 32 is guided, for example, in front of the passenger seat, toward a lower opening of the instrument panel 12B, and is drawn through the opening to the outside of the instrument panel 12B. Connectors for connecting to electrical components may be provided at the one end and the other end of the additional wiring member 32.

[0034] The path of the intermediate portion of the additional wiring member 32 is set appropriately depending on the positions of the connection destinations of both ends. Here, the intermediate portion of the additional wiring member 32 is arranged on the front pillar trim 12A and the instrument panel 12B from the interior side. In the present disclosure, even when the additional wiring member 32 is arranged along the seam 16, it is considered to be arranged on the interior member 12. The intermediate portion of the additional wiring member 32 is held at the seam 16 by the additional interior member 40. Here, the intermediate portion of the additional wiring member 32 and the additional interior member 40 extend along the seam 16.

[0035] The additional interior member 40 has a cover portion 42 and a holding portion 44. The cover portion 42 covers the additional wiring member 32. The holding portion 44 protrudes from the cover portion 42. The holding portion 44 is inserted into the joint 16 and held by the interior member 12.

[0036] The cover portion 42 is formed in a tubular shape. In the example shown in Fig. 2, the cover portion 42 is cylindrical, but the cover portion 42 may be in a rectangular tubular shape, for example. The cover portion 42 accommodates the additional wiring member 32. A slit 43 is formed in the cover portion 42 along the extending direction.

[0037] The retaining portion 44 protrudes outward from the outer surface of the cover portion 42. The retaining portion 44 protrudes from the edge of the slit 43. The tip portion of the retaining portion 44 is shaped to become thinner as it approaches the tip, and the tip portion of the retaining portion 44 may be provided with an inclined surface that is inclined in the direction of protrusion from the cover portion 42 (the vertical direction in Figure 2). This makes it easier to insert the tip portion of the retaining portion 44 into the seam 16. The base end portion of the retaining portion 44 may be continuous with a constant thickness along the protruding direction. This makes it easier for the retaining portion 44 inserted into the seam 16 to remain in the seam 16.

[0038] The retaining portion 44 extends over the entire length in the extension direction of the cover portion 42. The retaining portion 44 may be provided only on a portion of the cover portion 42 in the extension direction. In the example shown in FIG. 2 , the protruding dimension of the retaining portion 44 is shorter than the depth dimension of the seam 16 (the thickness dimension of the interior portion 13). The protruding dimension of the retaining portion 44 may be the same as or longer than the depth dimension of the seam 16 (the thickness dimension of the interior portion 13). The retaining portion 44 may pass through the seam 16 and protrude further outside the room than the interior member 12.

[0039] A space free of components extends around the opening of the joint 16 on the outdoor side. The area around the opening of the joint 16 on the outdoor side may be covered with components. In this case, the joint 16 is groove-shaped, and the component on the outdoor side of the joint 16 becomes the component at the bottom of the groove. The component on the outdoor side of the joint 16 may be part of the interior component 12, or may be a component separate from the interior component 12.

[0040] The retaining portion 44 has a first retaining portion 44A and a second retaining portion 44B. The first retaining portion 44A protrudes from a first edge of the slit 43. The second retaining portion 44B protrudes from a second edge of the slit 43. The first retaining portion 44A and the second retaining portion 44B extend parallel to each other from the cover portion 42. The first retaining portion 44A and the second retaining portion 44B are inserted into the seam 16.

[0041] The additional interior member 40 is made of, for example, resin. The additional interior member 40 is a molded product made using a mold. The additional interior member 40 is configured as a single component that includes a cover portion 42 and a holding portion 44. The additional interior member 40 may have higher rigidity than the additional wiring member 32. For example, the additional interior member 40 can be made higher rigidity than the additional wiring member 32 by being made of a relatively hard resin such as polypropylene (PP).

[0042] The additional interior member 40 may include a first part including the cover portion 42 and a second part including the holding portion 44. The additional interior member 40 may include a first part including the cover portion 42 and the holding portion 44, and a second part that serves as a reinforcing material for the holding portion 44. In this case, the second part may have higher rigidity than the first part.

[0043] The retaining portion 44 may be held by being press-fitted into the seam 16. For example, as shown in FIG. 4 , the width dimension of the seam 16 (the distance between adjacent interior portions 13) before the retaining portion 44 is inserted may be smaller than the thickness of the retaining portion 44. When the retaining portion 44 is inserted, the seam 16 may be deformed to widen or the retaining portion 44 may be deformed to become thinner. Such deformation increases the frictional force between the interior portion 13 that forms the seam 16 and the retaining portion 44, thereby holding the retaining portion 44 in place.

[0044] The retaining portion 44 may be locked to the seam 16. For example, the retaining portion 44 may have a tip locking portion that penetrates the seam and locks onto the surface of the interior portion 13 opposite the interior surface 14. Alternatively, for example, a recess may be formed in the wall portion that forms the seam, and the retaining portion may have a locking protrusion that fits into the recess to lock.

[0045] The seam 16 has a first seam and a second seam that are different from each other. The additional wiring member 32 has a first extending portion that extends along the first seam and a second extending portion that extends along the second seam. The additional interior member 40 has a first additional interior member that holds the first extending portion at the first seam and a second additional interior member that holds the second extending portion at the second seam.

[0046] Here, the intermediate portion of the additional wiring member 32 has an extension portion 34A extending from one end to the other end along a seam 16A between an edge 15A of the interior surface 14A of the pillar trim lower 13A and an edge 15B of the interior surface 14B of the instrument panel upper 13B, and an extension portion 34B extending along a seam 16B between an edge 15B of the interior surface 14B of the instrument panel upper 13B and an edge 15C of the interior surface 14C of the instrument panel lower 13C. One of the seam 16A and the seam 16B is an example of a first seam, and the other is an example of a second seam. One of the extension portion 34A and the extension portion 34B is an example of a first extension portion, and the other is an example of a second extension portion.

[0047] Here, seam 16A and seam 16B are provided in different sets of interior members 12. The first seam and second seam may be provided in the same set of interior members so as to extend in different directions. For example, in the case where the first interior part has an opening and the second interior part is a lid that covers the opening, the first seam and second seam may be considered to be the portions that extend and curve along the outer edge of the lid and the periphery of the opening.

[0048] The additional interior member 40A covers the extending portion 34A from the side opposite the pillar trim lower 13A and the upper instrument panel 13B. The additional interior member 40B covers the extending portion 34B from the side opposite the upper instrument panel 13B and the lower instrument panel 13C. One of the additional interior member 40A and the additional interior member 40B is an example of a first additional interior member, and the other is an example of a second additional interior member.

[0049] Here, the additional interior member 40A and the additional interior member 40B have the same cross-sectional shape. The additional interior member 40A and the additional interior member 40B may have cross-sectional shapes different from each other. For example, the additional interior member 40A and the additional interior member 40B may be made by cutting a long base material having a continuous same cross-sectional shape to lengths according to the joints 16A and 16B.

[0050] The additional interior member 40A may cover the entire portion of the extending portion 34A that is disposed along the seam 16A, or may cover only a portion of it. In FIG. 1, the additional interior member 40A covers the middle portion of the extending portion 34A that is disposed along the seam 16A, excluding both end portions. The additional interior member 40B may cover the entire portion of the extending portion 34B that is disposed along the seam 16B, or may cover only a portion of it. In FIG. 1, the additional interior member 40B covers the middle portion of the extending portion 34B that is disposed along the seam 16B, excluding both end portions. In this embodiment, the additional wiring member 32 has a bent portion 35 between the extending portions 34A and 34B. The bent portion 35 is bent and disposed between the additional interior member 40A and the additional interior member 40B so as to fit along the corner of the instrument panel upper 13B.

[0051] The interior portions 13 adjacent to each other via the seam 16 may be considered as a first interior portion and a second interior portion. For example, in the example shown in FIG. 2, one of the pillar trim lower 13A and the instrument panel upper 13B is an example of the first interior portion, and the other is an example of the second interior portion. Also, for example, in the example shown in FIG. 3, one of the instrument panel upper 13B and the instrument panel lower 13C is an example of the first interior portion, and the other is an example of the second interior portion. In this case, the seam 16 can be considered to be provided between the first interior portion and the second interior portion. Each of the first interior portion and the second interior portion faces the passenger compartment 11.

[0052] The first interior portion has a first interior surface facing the vehicle interior 11 and a first side surface extending from an edge of the first interior surface in a direction opposite the vehicle interior 11. The second interior portion has a second interior surface facing the vehicle interior 11 adjacent to the first interior surface and a second side surface extending from an edge of the second interior surface in a direction opposite the vehicle interior. A seam 16 is formed between the first side surface and the second side surface. Typically, the first side surface and the second side surface face each other. The first interior surface and the second interior surface may extend along the same plane, as shown in FIG. 2. The first interior surface and the second interior surface may extend along planes that intersect each other, as shown in FIG. 3.

[0053] Here, a first side portion of the cover portion 42 is located on the first interior surface, and a second side portion of the cover portion 42 is located on the second interior surface. A first protruding piece may be provided that protrudes from the outer surface of the cover portion 42 toward the first interior surface. The first protruding piece may be in contact with the first interior surface. A second protruding piece may be provided that protrudes from the outer surface of the cover portion 42 toward the second interior surface. The second protruding piece may be in contact with the second interior surface.

[0054] Here, the routing structure 30 for the additional wiring member further includes a shield portion 50. The shield portion 50 is provided between the cover portion 42 and the additional wiring member 32. The shield portion 50 may be attached to the inner surface of the cover portion 42. The shield portion 50 may be attached to the cover portion 42. The shield portion 50 may be incorporated into the cover portion 42. For example, the cover portion 42 may be insert molded using the shield portion 50 as an insert component. Even in this case, since the outer surface of the cover portion 42 is located outside the shield portion 50, the shield portion 50 can be considered to be provided between the cover portion 42 and the additional wiring member 32. The shield portion 50 may be a metal foil such as aluminum foil, or may be a braided wire.

[0055] A trunk line of a wiring member 22 is routed along the reinforcement 20 on the exterior side of the instrument panel 12B. The wiring member 22 is also called an instrument panel wire harness or an instrument panel harness. The wiring member 22 includes electric wires 23 connected to electric components arranged around the instrument panel 12B. The electric wires 23 may have a configuration similar to that of the electric wires 33. The electric components to which the wiring member 22 is connected may be, for example, an ECU arranged on the exterior side of the instrument panel 12B. Furthermore, the electric components may be, for example, meters, operation switches, audio electric components, etc., mounted on the instrument panel 12B. The wiring member 22 may include electric wires connected via connectors or the like to electric wires included in an engine room harness, door harness, roof harness, floor harness, etc. (so-called electric wires for wire-to-wire connection). The number of electric wires 23 included in the wiring member 22 is not particularly limited, and may be greater than the number of electric wires 33 included in the additional wiring member 32. For example, the number of electric wires 23 included in the wiring member 22 may be several tens or more, or several hundreds or more. The wiring member 22 may be provided with a plurality of branches.

[0056] The intermediate portion of the additional wiring member 32 may extend parallel to the intermediate portion of the wiring member 22 toward a connection destination located in the same space as the connection destination of the wiring member 22. In this case, the intermediate portion of the wiring member 22 may be routed further exterior than the interior member 12, and the intermediate portion of the additional wiring member 32 may be routed further interior than the interior member 12. The intermediate portion of the wiring member 22 may be disposed in the space between the interior member 12 and an exterior member located further exterior than the interior member 12. The interior member 12 may separate the wiring member 22 and the additional wiring member 32. For example, the connection destination of the additional wiring member 32 and the connection destination of the wiring member 22 may both be located within the roof trim, the wiring member 22 may be routed further exterior than the front pillar trim 12A and the instrument panel 12B, and the additional wiring member 32 may be routed further interior than the front pillar trim 12A and the instrument panel 12B.

[0057] It is assumed that the additional wiring member 32 is routed in the vehicle 10 after the wiring member 22 has been routed. For example, the wiring member 22 may be incorporated into the vehicle 10 during the manufacturing stage of the vehicle 10, and the additional wiring member 32 may be incorporated into the vehicle 10 after the manufacturing stage of the vehicle 10. Also, for example, the wiring member 22 may be incorporated into the vehicle 10 at a stage before the vehicle 10 is delivered to the user as a new vehicle, and the additional wiring member 32 may be incorporated into the vehicle 10 at a stage after the vehicle 10 is delivered to the user as a new vehicle.

[0058] <Effects, etc.> According to the routing structure 30 for the additional wiring member configured as described above, the additional wiring member 32 can be easily routed onto the interior member 12 via the additional interior member 40. This makes it possible to easily add the wiring member 22 to the vehicle 10.

[0059] The instrument panel 12B or the front pillar trim 12A, which are the interior member 12, cover the wiring member 22, and the additional wiring member 32 is arranged along a path separate from that of the wiring member 22. Therefore, the additional wiring member 32 can be added without modifying the existing wiring member 22. Because there is no need to modify the existing wiring member 22, it is possible to prevent the position of the wiring member 22 from being changed and the influence of noise from increasing.

[0060] The present disclosure can also be regarded as a wiring system for a vehicle 10 that includes a wiring structure 30 for an additional wiring member located on the passenger compartment side of the interior member 12 and a wiring structure for a wiring member 22 located on the passenger compartment side of the interior member 12. When another electrical component is to be added to an existing vehicle 10, such a wiring system is suitable as a system for easily adding an additional wiring member 32 for the electrical component.

[0061] Moreover, the cover portion 42 is formed in a cylindrical shape and houses the additional wiring member 32, and the holding portion 44 protrudes outward from the outer surface of the cover portion 42. This makes it possible to easily add the wiring member 22 to the vehicle 10 by holding the additional interior member 40 that houses the additional wiring member 32 in the interior member 12.

[0062] Furthermore, a slit 43 is formed in the cover portion 42 along the extension direction, and the holding portion 44 protrudes from the edge of the slit 43. This makes it easy to store the additional wiring member 32 inside the cover portion 42 through the slit 43. It also makes it easy to align the edge of the slit 43 with the seam 16.

[0063] Furthermore, the retaining portion 44 has a first retaining portion 44A that protrudes from a first edge of the slit 43 and a second retaining portion 44B that protrudes from a second edge of the slit 43, and the first retaining portion 44A and the second retaining portion 44B are inserted into the seam 16. This prevents the slit 43 from opening.

[0064] Furthermore, the additional interior member 40 has higher rigidity than the additional wiring member 32. This makes it easier to insert the holding portion 44 into the joint 16.

[0065] Furthermore, the additional wiring member 32 and the additional interior member 40 extend along the seam 16. The portion of the interior member 12 at the seam 16 is originally a portion where a discontinuous design appears. Because the additional wiring member 32 and the additional interior member 40 extend along the seam 16, occupants are less likely to feel uncomfortable with the design due to the routing of the additional wiring member 32 compared to a state in which the additional wiring member 32 is not routed.

[0066] Furthermore, the joint 16 has a joint 16A and a joint 16B that are different from each other, the additional wiring member 32 has an extending portion 34A that extends along the joint 16A and an extending portion 34B that extends along the joint 16B, and the additional interior member 40 has an additional interior member 40A that holds the extending portion 34A at the joint 16A and an additional interior member 40B that holds the extending portion 34B at the joint 16B. This makes it easy to route the additional wiring member 32 in the vehicle 10 even if the same joint 16 is not continuous from one end to the other end of the additional wiring member 32.

[0067] Furthermore, the wiring structure 30 for the additional wiring member includes a shield portion 50 provided between the cover portion 42 and the additional wiring member 32. This allows noise from the additional wiring member 32 to be suppressed by the shield inside the additional interior member 40.

[0068] [Note] Up to now, it has been described that the cover portion 42 is formed in a cylindrical shape and houses the additional wiring member 32, and that the holding portion 44 protrudes outward from the outer surface of the cover portion 42, but this is not a required configuration. For example, the cover portion 42 may be formed in a plate shape that covers the additional wiring member 32, and the holding portion 44 may protrude from the main surface of the cover portion 42 that faces the interior member 12.

[0069] Although it has been described above that the slit 43 is formed in the cover portion 42 and the holding portion 44 protrudes from the edge of the slit 43, this is not a required configuration. For example, the cover portion 42 does not need to have the slit 43 formed along the extension direction. Also, for example, the holding portion 44 may protrude from a portion of the cover portion 42 other than the edge of the slit 43.

[0070] Furthermore, although the retaining portion 44 has been described above as having a first retaining portion 44A and a second retaining portion 44B, and the first retaining portion 44A and the second retaining portion 44B being inserted into the seam 16, this is not a required configuration. For example, the retaining portion 44 may have only one of the first retaining portion 44A and the second retaining portion 44B. Also, for example, if the retaining portion 44 has the first retaining portion 44A and the second retaining portion 44B, only one of the first retaining portion 44A and the second retaining portion 44B may be inserted into the seam 16.

[0071] Furthermore, although the additional interior member 40 has been described above as having higher rigidity than the additional wiring member 32, this is not an essential configuration. For example, the rigidity of the additional interior member 40 may be the same as or lower than the rigidity of the additional wiring member 32.

[0072] Furthermore, although the additional wiring member 32 and the additional interior member 40 have been described above as extending along the seam 16, this is not a required configuration. For example, the additional wiring member 32 and the additional interior member 40 may extend so as to cross the seam 16. In this case, the cover portion 42 may be provided at the portion crossing the seam 16 and at portions before and after it, and the retaining portion 44 may be provided partially at the portion of the cover portion 42 crossing the seam 16. Furthermore, the additional wiring member 32 and the additional interior member 40 do not have to extend along multiple seams 16.

[0073] Furthermore, although the wiring structure 30 for the additional wiring member has been described so far as including the shield portion 50 provided between the cover portion 42 and the additional wiring member 32, this is not an essential configuration. The shield portion 50 does not have to be provided.

[0074] 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]
