Description

Technical Field

[0001] This invention relates to wire harnesses. Background Technology

[0002] Conventionally, vehicles such as automobiles have wiring harnesses that electrically connect power sources (such as secondary batteries) and electrical components on the vehicle body side to switches and electrical components on the sliding door side. These wiring harnesses are routed by laying the main body of the harness between the vehicle body and the sliding door, and the routing path of the main body of the harness changes in conjunction with the opening and closing action of the sliding door. Such wiring harnesses are disclosed, for example, in Patent Document 1 described below.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2011-19386 Summary of the Invention

[0006] The technical problem that the invention aims to solve

[0007] Furthermore, in a vehicle, the sliding mechanism responsible for the sliding action of the sliding door is assembled between the sliding door and the vehicle body. For example, in a vehicle, a linkage mechanism mounted between the sliding door and the vehicle body is considered as the sliding mechanism. Moreover, in this vehicle, it is considered to route the wiring harness body along the linkage mechanism. In this case, the wiring harness body follows the movement of the linkage mechanism, but it is not preferable to overload the wiring harness body due to excessive bending or the like.

[0008] Therefore, the object of the present invention is to provide a wire harness that enables the wire harness body to follow the movement of the linkage mechanism without overload.

[0009] Technical means for solving problems

[0010] The wiring harness of the present invention is characterized by comprising: a wiring harness body having: a first wiring portion, the first wiring portion being routed to a linkage mechanism, the linkage mechanism connecting a vehicle body to a sliding door and causing the sliding door to reciprocate relative to the vehicle body in a sliding direction; a second wiring portion, the second wiring portion being routed at a position closer to the vehicle body than the first wiring portion; and a third wiring portion, the third wiring portion being routed at a position closer to the sliding door than the first wiring portion; and a wiring harness fixing member, the wiring harness fixing member fixing a fixing portion of the third wiring portion to a fixing portion, the fixing portion being not The linkage mechanism includes: a configuration for relative displacement with respect to the sliding door; and a wiring harness guide that restricts the wiring path of the third wiring portion. The linkage mechanism comprises: a first arm member, one end of which is connected to the vehicle body side and the first wiring portion is routed to the other end of the first arm member; a second arm member, one end of which is connected to the sliding door side; and a first rotation axis, which has an axial direction orthogonal to the sliding direction and allows for a first relative rotation between the vehicle body and the one end of the first arm member. The linkage mechanism includes a second rotation axis, parallel to the first rotation axis, which allows for a second relative rotation between the other end of the first arm component where the wiring harness guide is fixed and the other end of the second arm component; and a third rotation axis, parallel to both the first and second rotation axes, which allows for a third relative rotation between the sliding door and one end of the second arm component. The linkage mechanism causes the sliding door to reciprocate relative to the vehicle body in the sliding direction along an orthogonal plane orthogonal to the first, second, and third rotation axes. The wiring harness guide guides the third wiring portion toward the fixed portion on the sliding door side. The fixed portion is located relative to the wiring harness guide in a direction intersecting the orthogonal plane. When the relative rotation position of the second arm component relative to the sliding door about the third rotation axis is at the center of the swing amplitude of the third relative rotation, the fixed portion on the sliding door side is located on the plane where the centers of the second and third rotation axes are respectively located and relative to the wiring harness guide in a direction intersecting the orthogonal plane.

[0011] Invention Effects

[0012] In the wiring harness of this invention, since the fixed portion on the sliding door side is provided on the aforementioned plane and in a direction intersecting the orthogonal plane with respect to the wiring harness guide, the third wiring portion can bend and deform with the same amount of deformation when the second arm member rotates relative to the sliding door about the third rotation axis from the center position of the third relative rotation amplitude to one end and from the center position of the swing amplitude to the other end. Therefore, when the second arm member rotates relative to the sliding door about the third rotation axis, the bending deformation of the third wiring portion can be minimized. Therefore, the wiring harness of this invention can make the wiring harness body follow the movement of the linkage mechanism without overload when the linkage mechanism performs the third relative rotation.

[0049] The embodiments of the wire harness according to the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the present invention is not limited to this embodiment.

[0050] [Implementation Method]

[0051] based on Figures 1 to 11 One embodiment of the wire harness involved in this invention will be described.

[0052] Figures 1 to 11 The symbol 1 indicates the wiring harness in this embodiment.

[0053] For example, in vehicles such as automobiles, there exists a sliding door 520 that is capable of reciprocating in a sliding direction relative to the vehicle body 510. Figures 1 to 11 The vehicle is equipped with a linkage mechanism 600 to enable the sliding door 520 to slide (reciprocating movement in the sliding direction). This linkage mechanism 600 connects the vehicle body 510 to the sliding door 520 and causes the sliding door 520 to reciprocate relative to the vehicle body 510 in the sliding direction. Figures 1 to 11 The linkage mechanism 600 shown here causes the sliding door 520 on the side of the vehicle to slide along the front-rear direction of the vehicle.

[0054] The linkage mechanism 600 is mounted between the vehicle body 510 and the sliding door 520, so that the sliding door 520 is in the fully closed position. Figures 1 to 4 ) and fully open position ( Figure 5 and Figure 6 The linkage mechanism 600 is displaced relative to the vehicle body 510 via the sliding door 520 at a predetermined half-open position. Figure 7 as well as Figure 8 The linkage mechanism 600 is displaced relative to the vehicle body 510 between the fully closed and fully open positions. The linkage mechanism 600 includes: a first arm member 610, which connects one end 611 to the side of the vehicle body 510; and a second arm member 620, which connects one end 621 to the side of the sliding door 520. Figures 1 to 11 ).

[0055] Furthermore, the linkage mechanism 600 includes: a first rotation axis 631, which enables a first relative rotation between the vehicle body 510 and one end 611 of the first arm member 610; a second rotation axis 641, parallel to the first rotation axis 631, enabling a second relative rotation between the other end 612 of the first arm member 610 and the other end 622 of the second arm member 620; and a third rotation axis 651, parallel to the first rotation axis 631 and the second rotation axis 641, enabling a third relative rotation between the sliding door 520 and one end 621 of the second arm member 620. Figures 1 to 11 The first rotating shaft 631, the second rotating shaft 641, and the third rotating shaft 651 are respectively axial in a direction orthogonal to the sliding direction. The first rotating shaft 631, the second rotating shaft 641, and the third rotating shaft 651 shown here are respectively axial in a direction orthogonal to the sliding direction (vehicle front-to-back direction) and the vehicle width direction (i.e., vehicle vertical direction).

[0056] The linkage mechanism 600 causes the sliding door 520 to reciprocate in the sliding direction along an orthogonal plane (hereinafter referred to as the "operating plane of the linkage mechanism 600") Pm that is orthogonal to the first rotation axis 631, the second rotation axis 641, and the third rotation axis 651. Figure 4 and Figure 10 ).

[0057] In this linkage mechanism 600, the output torque of the rotary machine (not shown) which serves as the drive source is transmitted to the first rotating shaft 631.

[0058] For example, the first rotating shaft 631 shown here is fixed to one end 611 of the first arm component 610 in a manner without relative displacement, and operates integrally with the first arm component 610. Furthermore, the linkage mechanism 600 shown here includes a bearing component 632, which is fixed to the vehicle body 510 and rotatably supports the first rotating shaft 631. Figures 1 to 11 The bearing component 632 is fixed to the body side of the vehicle body 510 in a manner without relative displacement. In this linkage mechanism 600, a first rotation shaft 631 and a bearing component 632 are provided as a connecting member that allows the fixed portion 510a of the vehicle body 510 and one end 611 of the first arm component 610 to rotate freely relative to each other. Therefore, the linkage mechanism 600 allows the first arm component 610 to rotate relative to the fixed portion 510a of the vehicle body 510 about the first rotation shaft 631.

[0059] Additionally, for example, in the linkage mechanism 600 shown here, a bearing portion 642 that rotatably supports the second rotating shaft 641 is provided at the other end 612 of the first arm member 610. Figures 1 to 11Furthermore, in the linkage mechanism 600 shown here, a bearing portion 643 that rotatably supports the second rotating shaft 641 is provided at the other end 622 of the second arm member 620. Figures 1 to 11 Therefore, the first arm component 610 and the second arm component 620 are connected to each other via the second rotating shaft 641, bearing portion 642, and bearing portion 643 in a manner that allows them to rotate relative to each other about the second rotating shaft 641. Alternatively, in this linkage mechanism 600, the second rotating shaft 641 can be fixed to one of the other end 612 of the first arm component 610 and the other end 622 of the second arm component 620 without relative displacement.

[0060] The third rotating shaft 651 is supported by a bearing portion provided at least one of the end portion 621 of the second arm member 620 and the fixed portion 520a of the sliding door 520. For example, in the linkage mechanism 600 shown here, the bearing portion 652 that rotatably supports the third rotating shaft 651 is provided at the end portion 621 of the second arm member 620. Figures 1 to 11 Furthermore, the fixed portion 520a of the sliding door 520 shown here is formed as a bearing portion that rotatably supports the third rotation axis 651. Therefore, the second arm member 620 and the sliding door 520 are connected to each other via the third rotation axis 651, the bearing portion 652 and the fixed portion 520a in a manner that allows them to rotate relative to each other about the third rotation axis 651.

[0061] When the sliding door 520 is in the fully closed position, the first arm component 610 shown here is configured to extend in the sliding direction (vehicle longitudinal direction). Figures 1 to 4 Furthermore, when the sliding door 520 is opened from its fully closed position, the linkage mechanism 600 causes the first arm component 610 to rotate relative to the vehicle body 510 about the first rotation axis 631 toward the exterior side of the vehicle. Figures 1 to 11 ).

[0062] Furthermore, regardless of the position of the sliding door 520, the second arm member 620 shown here extends further into the vehicle interior than the second rotation axis 641, and provides a axial support for the third rotation axis 651 in front of its extension. That is, regardless of the position of the sliding door 520, the third rotation axis 651 shown here is positioned closer to the vehicle interior than the second rotation axis 641. Therefore, the fixed portion 520a of the sliding door 520 protrudes from, for example, the inner panel 520b of the sliding door 520 to a position closer to the vehicle interior than the second rotation axis 641, and provides a axial support for the third rotation axis 651 in front of its protrusion. The linkage mechanism 600 causes the second arm member 620 to rotate relative to the sliding door 520 about the third rotation axis 651 within a range of a third relative rotation swing amplitude Wθ. Figure 9 ).

[0063] When the sliding door 520 is in the fully closed position, the linkage mechanism 600 positions the second arm component 620 at one end of the third relative rotational swing amplitude Wθ. Figures 1 to 4 , Figure 9 as well as Figure 10 When the sliding door 520 is in the fully open position, the linkage mechanism 600 positions the second arm component 620 at the other end of the third relative rotational swing amplitude Wθ. Figure 5 , Figure 6 as well as Figure 11 ).

[0064] When the sliding door 520 moves from the fully closed position to the predetermined half-open position, the linkage mechanism 600 moves the second arm component 620 from one end of the third relative rotational swing amplitude Wθ to the other end. When the sliding door 520 moves from its half-open position to the fully closed position, the linkage mechanism 600 moves the second arm component 620 from the other end of the third relative rotational swing amplitude Wθ to one end. Figures 1 to 4 as well as Figures 7 to 10 For example, when the linkage mechanism 600 moves the sliding door 520 from the fully closed position to the fully open position, it causes the first arm member 610 to rotate relative to the vehicle body 510 about a first rotation axis 631. Simultaneously, the second arm member 620, located at one end of the third relative rotation swing amplitude Wθ relative to the sliding door 520, rotates relative to the first arm member 610 about a second rotation axis 641 and relative to the sliding door 520 about a third rotation axis 651, thereby causing the second arm member 620 to reach the other end of the third relative rotation swing amplitude Wθ relative to the sliding door 520. By operating in this way, the linkage mechanism 600 moves the sliding door 520 from the fully closed position to a predetermined half-open position. Furthermore, the predetermined half-open position of the sliding door 520 referred to here is the position of the sliding door 520 relative to the vehicle body 510 when the second arm member 620 is displaced from one end of the third relative rotation swing amplitude Wθ to the other end.

[0065] Next, the linkage mechanism 600 causes the first arm component to continue rotating relative to the vehicle body 510 about the first rotation axis 631, and while maintaining the second arm component 620 at the other end of the swing amplitude Wθ of the third relative rotation relative to the sliding door 520, it causes the first arm component 610 to rotate relative to the second arm component 620 about the second rotation axis 641. Figures 5 to 8 as well as Figure 11 That is, when the sliding door 520 is between a predetermined half-open position and a fully open position, the linkage mechanism 600 maintains the second arm component 620 positioned at the other end of a third relative rotational swing amplitude Wθ. Through this action, the linkage mechanism 600 moves the sliding door 520 from the predetermined half-open position to the fully open position.

[0066] On the other hand, when the sliding door 520 is moved from the fully open position to the fully closed position, the linkage mechanism 600 causes the first arm member 610 to rotate relative to the vehicle body 510 about the first rotation axis 631 (in the opposite direction to the opening action), and in a state where the second arm member 620 is at the other end of the swing amplitude Wθ of the third relative rotation relative to the sliding door 520, the first arm member 610 is rotated relative to the second arm member 620 about the second rotation axis 641 (in the opposite direction to the opening action). Figures 5 to 8 as well as Figure 11 Through this action, the linkage mechanism 600 moves the sliding door 520 from the fully open position to the predetermined half-open position.

[0067] Next, the linkage mechanism 600 causes the first arm component to continue rotating relative to the vehicle body 510 about the first rotation axis 631, while simultaneously causing the second arm component 620, located at the other end of the third relative rotation swing amplitude Wθ relative to the sliding door 520, to rotate relative to the first arm component 610 about the second rotation axis 641 (opposite to the opening action) and relative to the sliding door 520 about the third rotation axis 651 (opposite to the opening action), thereby causing the second arm component 620 to reach one end of the swing amplitude Wθ relative to the sliding door 520. Figures 1 to 4 as well as Figures 7 to 10 Through this action, the linkage mechanism 600 moves the sliding door 520 from the half-open position to the fully closed position.

[0068] In this embodiment, the wiring harness 1 is mounted on the vehicle to electrically connect a first electrical connection object 511 provided on the vehicle body 510 to a second electrical connection object 521 provided on the sliding door 520. Figure 1 ).

[0069] The first electrical connection object 511 is a component located on the vehicle body 510 side, such as a power source (secondary battery, etc.) or electrical components. For example, the electrical components on the vehicle body 510 side include audio equipment associated with the speaker of the sliding door 520, a drive mechanism for driving the power seat, etc. On the other hand, the second electrical connection object 521 is a component located on the sliding door 520, such as an electrical component or a switch. For example, the electrical components of the sliding door 520 include a drive mechanism for driving the power window, a speaker, etc. Furthermore, the switches of the sliding door 520 include switches for operating the power window, switches for operating the power seat, etc.

[0070] The wiring harness 1 is routed between the first electrical connection object 511 and the second electrical connection object 521. Figure 1 Furthermore, the wiring harness 1 is routed to the linkage mechanism 600 and follows the movement of the linkage mechanism 600.

[0071] The wire harness 1 includes a wire harness body 10, which serves as a wiring component for electrically connecting a first electrical connection object 511 to a second electrical connection object 521. Figures 1 to 11 The main body 10 of the wiring harness may consist of a single wire bundle consisting of multiple wires, or it may be entirely covered by an external component such as a corrugated pipe, or it may be partially covered by one or more external components. Additionally, the wiring harness 1 may also include a communication line for transmitting and receiving signals between the vehicle body 510 side and the sliding door 520 side.

[0072] In this wire harness 1, one end of the wire harness body 10 is directly or indirectly electrically connected to a first electrical connection object 511, and the other end of the wire harness body 10 is directly or indirectly electrically connected to a second electrical connection object 521. For example, the wire harness 1 includes: a first connector 21 assembled at one end of the wire harness body 10, allowing the wire harness body 10 to be directly or indirectly electrically connected to the first electrical connection object 511; and a second connector 22 assembled at the other end of the wire harness body 10, allowing the wire harness body 10 to be directly or indirectly electrically connected to the second electrical connection object 521. Figures 1 to 11 ).

[0073] The wiring harness body 10 includes: a first wiring portion 11, which is wired to the linkage mechanism 600; a second wiring portion 12, which is wired at a position closer to the vehicle body 510 than the first wiring portion 11; and a third wiring portion 13, which is wired at a position closer to the sliding door 520 than the first wiring portion 11. Figures 1 to 11 ).

[0074] The first wiring portion 11 is wired to the other end 612 of the first arm component 610. Figures 1 to 11 For example, the first wiring portion 11 is routed along the first arm member 610 to the other end 612 of the first arm member 610. The first wiring portion 11 shown here extends along the first arm member 610 between one end 611 and the other end 612. The first wiring portion 11 may be fixed to the first arm member 610 at one end 611 using a wire harness fastener (hereinafter referred to as an "arm-side fastener") (not shown), or it may not be fixed at one end 611. Furthermore, the arm-side fastener may be, for example, a clamp or clip that retains the shape of both the first wiring portion 11 and the first arm member 610 (e.g., a flat portion), or a resin tape that winds the first wiring portion 11 and the first arm member 610 together.

[0075] For example, in the wiring harness body 10, when the first wiring portion 11 is routed between one end 611 and the other end 612 of the first arm member 610, the second wiring portion 12 is the portion routed further towards the vehicle body 510 than the one end 611 of the first arm member 610. Figures 1 to 11 In the wiring harness body 10, the first connector 21 at the end of the second wiring section 12 is electrically connected directly or indirectly to the first electrical connection object 511 on the vehicle body 510 side.

[0076] The second wiring section 12 may be directly or indirectly fixed to the vehicle body 510, or it may not be fixed to the vehicle body 510 in this way. When the second wiring section 12 is fixed to the vehicle body 510, for example, a wire harness fastener (hereinafter referred to as "first wire harness fastener") is used for this fixation (illustration omitted). The first wire harness fastener is, for example, a clamp or clip that is provided with a shape-holding device for the second wiring section 12 and the vehicle body 510 or a component fixed to the vehicle body 510 (e.g., a flat plate portion).

[0077] Additionally, the third wiring section 13 is the portion of the wiring harness body 10 that is routed to the side of the sliding door 520 at the other end 612 of the first arm member 610. Figures 1 to 11 In the wire harness body 10, the second connector 22 at the end of the third wiring section 13 is directly or indirectly electrically connected to the second electrical connection object 521.

[0078] The third wiring portion 13 is fixed to the fixed portion 522 on the sliding door 520 side between the end of the second electrical connection object 521 side and the end of the first wiring portion 11 side. The fixed portion 522 is arranged in a manner that does not cause relative displacement with respect to the sliding door 520. Figure 1 The fixed portion 522 on the sliding door 520 side can be a part provided on the sliding door 520, or it can be a part of other components fixed in a manner that does not have relative displacement with respect to the sliding door 520. The linkage mechanism 600 includes a wire harness fixing member (hereinafter referred to as "second wire harness fixing member") 30, which fixes the fixing portion 13a between the end of the second electrical connection object 521 side and the end of the first wire harness 11 side in the third wiring portion 13 to the fixed portion 522 on the sliding door 520 side. Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 as well as Figure 10 For example, the second wiring harness fixing member 30 refers to a clamp or clip that is provided with a shape-holding clamp for the fixing part 522 provided for the fixing part 13a of the third wiring part 13 and the through hole provided in the sliding door 520 (e.g., a part formed as a flat plate).

[0079] Furthermore, the linkage mechanism 600 includes a wire harness guide 40, which is fixed to the other end 612 of the first arm member 610 and restricts the wiring path of the third wiring section 13. Figures 1 to 11 The wiring harness guide 40 is a guide member that guides the third wiring portion 13 toward the fixed portion 522 on the sliding door 520 side. The fixed portion 522 is located relative to the wiring harness guide 40 in a direction intersecting with the operating plane Pm of the linkage mechanism 600. The wiring harness guide 40 is fixed relative to the other end 612 of the first arm member 610 in a manner without relative displacement, guiding the third wiring portion 13 from the end on the first wiring portion 11 side toward the fixed portion 522 on the sliding door 520 side.

[0080] When the second arm component 620 is at the center of the swing amplitude Wθ of the third relative rotation relative to the sliding door 520 about the third rotation axis 651, the fixed part 522 on the sliding door 520 side is located on the plane (hereinafter referred to as the "imaginary plane") Pi where the centers of the second rotation axis 641 and the third rotation axis 651 are respectively, and is provided relative to the wire harness guide 40 in a direction intersecting the action plane Pm of the linkage mechanism 600. Figure 1 as well as Figure 10 ).

[0081] The wiring harness guide 40 has: an inlet 41 for introducing a first wiring portion 11 that is wired along the first arm member 610 to the other end 612 of the first arm member 610; an outlet 42 for leading out a third wiring portion 13 toward the fixed portion 522 on the sliding door 520 side; and a guide space 43 for guiding the first wiring portion 11 introduced from the inlet 41 and guiding the third wiring portion 13 to the outlet 42. Figure 2 The main body of the wire harness guide 40 shown here is formed in an L-shaped cylindrical shape, and the internal space of the wire harness guide 40 is used as an L-shaped guide space 43 for guiding the first wiring portion 11 and the third wiring portion 13. Furthermore, the wire harness guide 40 opens its outlet 42 axially in the first rotation axis 631 and the second rotation axis 641, so that the third wiring portion 13 faces the fixed portion 522 on the side of the sliding door 520 located in front of the outlet 42. The wire harness guide 40, for example, leads out the third wiring portion 13 along the axis of the second rotation axis 641. Therefore, the outlet 42 is provided on the axis of the second rotation axis 641, and the third wiring portion 13 is led out along this axis.

[0082] The fixed portion 522 on the sliding door 520 side is positioned relative to the wiring harness guide 40 in an area above or below the vehicle. For example, when the second arm member 620 is at the center of the third relative rotational swing amplitude Wθ relative to the sliding door 520 about the third rotation axis 651, the fixed portion 522 is positioned relative to the wiring harness guide 40 in an area above or below the vehicle. When the second arm member 620 is at this center position, the fixed portion 522 shown here is positioned relative to the wiring harness guide 40 in an area above the vehicle. Specifically, when the second arm member 620 is at the center position of the third relative rotational swing amplitude Wθ, the fixed portion 522 is positioned relative to the wiring harness guide 40 in an area above the vehicle, and the fixing portion 13a of the third wiring portion 13, which is positioned relative to the wiring harness guide 40, can be fixed using the second wiring harness fixing member 30. For example, when the second arm component 620 is in the center position of the third relative rotation swing amplitude Wθ, the third wiring portion 13 is led out from the outlet 42 of the wiring harness guide 40 toward the vehicle, and the fixing portion 13a located above the vehicle than the outlet 42 is fixed to the fixed portion 522 on the side of the sliding door 520 by the second wiring harness fixing member 30.

[0083] The end of the third wiring section 13 on the first wiring section 11 side is constrained in the configuration of the wire harness guide 40, which follows the movement and position of the first arm member 610, and the fixing part 13a of the third wiring section 13 is constrained in the position of the fixed part 522 on the sliding door 520 side. Therefore, when the second arm member 620 is rotated relative to the sliding door 520 about the third rotation axis 651, the position of the fixed part 522 of the wire harness guide 40 relative to the sliding door 520 side moves in a manner linked to the displacement of the other end 622 of the second arm member 620 (the other end 612 of the first arm member 610). Therefore, the third wiring section 13 can follow the displacement of the wire harness guide 40 and bend with suppressed deformation between the wire harness guide 40 and the fixing part 13a. Figure 9 as well as Figure 10 That is, the harness 1 can make the harness body 10 follow the movement of the linkage mechanism 600 without overload.

[0084] Specifically, since the fixed portion 522 on the sliding door 520 side is positioned on the imaginary plane Pi and in a direction intersecting the operating plane Pm of the linkage mechanism 600 relative to the wiring harness guide 40, the third wiring portion 13 can bend and deform with the same amount of deformation when the second arm member 620 rotates relative to the sliding door 520 about the third rotation axis 651 from the center position of the third relative rotation swing amplitude Wθ to one end and from the center position of the swing amplitude Wθ to the other end. Therefore, when the second arm member 620 rotates relative to the sliding door 520 about the third rotation axis 651, the wiring harness 1 can minimize the bending deformation of the third wiring portion 13. Therefore, when the linkage mechanism 600 performs the third relative rotation, the wiring harness 1 can make the wiring harness body 10 follow the movement of the linkage mechanism 600 without overload.

[0085] Furthermore, when the first arm component 610 and the second arm component 620 rotate relative to each other about the second rotation axis 641, the first wiring portion 11 rotates about the third wiring portion 13 in conjunction with the movement of the first arm component 610. Therefore, the third wiring portion 13 can suppress the amount of deformation between the wire harness guide 40 and the fixing portion 13a and undergo torsional deformation about its own axis. Figure 11 That is, the harness 1 can make the harness body 10 follow the movement of the linkage mechanism 600 without overload.

[0086] Specifically, since the third wiring portion 13 extends from the wire harness guide 40 along the axis of the second rotation axis 641, it can undergo torsional deformation along or near the axis of the second rotation axis 641. Therefore, in this third wiring portion 13, compared to the case where it extends from the wire harness guide 40 at a position away from the axis of the second rotation axis 641, torsional deformation with suppressed deformation can be performed. Therefore, when the first arm member 610 and the second arm member 620 rotate relative to each other about the second rotation axis 641, the wire harness 1 can cause the wire harness body 10 to follow the movement of the linkage mechanism 600 without overload.

[0087] Furthermore, the second arm component 620 shown here extends along the vehicle width direction when it is at the center of the third relative rotational swing amplitude Wθ relative to the sliding door 520 about the third rotational axis 651, and the second rotational axis 641 and the third rotational axis 651 are arranged in this vehicle width direction. Therefore, the imaginary plane Pi shown here refers to the plane that is orthogonal to the vehicle width direction and the vehicle vertical direction and the vehicle front-rear direction (sliding direction) when the second arm component 620 is at this center position. In addition, the second arm component 620 rotates relative to one end and the other end of the axial swing amplitude Wθ of the third relative rotational axis 651 of the sliding door 520 from the center position of the third relative rotational swing amplitude Wθ by the same angle.

[0088] As shown above, the wiring harness 1 of this embodiment can make the wiring harness body 10 follow the movement of the linkage mechanism 600 without overload, thus improving the durability of the wiring harness body 10.
