[0035] Referring to the accompanying drawings, the embodiments (implementations) for carrying out the present invention will be described in detail. The present invention is not limited to the contents described in the following embodiments. Furthermore, the constituent elements described below include contents readily conceived by those skilled in the art and substantially the same contents. Moreover, the structures described below can be appropriately combined. Furthermore, various omissions, substitutions, or modifications to the structure can be made without departing from the spirit of the present invention.

[0036] [Implementation Method]

[0037] The wiring harness layout structure 1, the linkage sliding door SD, and the wiring harness WH involved in the embodiment will be described with reference to the accompanying drawings.

[0038] In the following description, the first direction among the intersecting first, second, and third directions will be referred to as the "extension direction X", the second direction as the "width direction Y", and the third direction as the "height direction Z (intersecting direction Z)". The extension direction X, width direction Y, and height direction Z intersect each other, typically orthogonally. The extension direction X is, for example, along the extension direction (length direction) of the main link arm 11, which will be described later. The width direction Y is, for example, along the direction of the short side of the main link arm 11. The height direction Z is along the vehicle height direction (vehicle height direction) of the vehicle, and also along the vertical direction. The sliding direction S of the door body D is along the extension direction X of the main link arm 11 when the door body D is closed, which here is equivalent to the direction along the entire length of the vehicle body B. In other words, the sliding direction S of the door body D is a direction that intersects the rotation axis of the main link arm 11 (rotation axis portions 12a and 13a, described later), typically orthogonal to the rotation axis. Unless otherwise specified, all directions used in the following description refer to the directions in the assembled state of the parts.

[0039] The wiring harness layout structure 1 is applied to a vehicle, supporting the door body D so that it can slide relative to the vehicle body B along the sliding direction S (the entire length of the vehicle body B), and electrically connecting the connection objects BC1 of the equipment, connectors, etc., located on the side of the vehicle body B to the connection objects DC1 of the equipment, connectors, etc., located on the side of the door body D. For example... Figures 1 to 4 As shown, the wiring harness layout structure 1 includes wiring W, a main linkage mechanism 10, a secondary linkage mechanism 20, a cover 30, and a binding component 40. Wiring W, cover 30, and binding component 40 constitute the wiring harness WH. In other words, the wiring harness WH can be described as having wiring W, cover 30, and binding component 40. Furthermore, the door body D, main linkage mechanism 10, secondary linkage mechanism 20, cover 30, binding component 40, and wiring W constitute the linkage-type sliding door SD. In other words, the linkage-type sliding door SD can be described as having door body D, main linkage mechanism 10, secondary linkage mechanism 20, cover 30, binding component 40, and wiring W.

[0040] Here, the wiring harness layout structure 1 does not use a conventional sliding guide rail. Instead, it is a layout structure in which the door body D is slidably moved relative to the vehicle body B along the sliding direction S by the main linkage mechanism 10 and the secondary linkage mechanism 20 supporting the door body D and rotating the main linkage arm 11 and the secondary linkage arm 21 (described later). The wiring harness layout structure 1 will be described in detail below.

[0041] Wiring W connects connection object BC1 located on the B side of the vehicle body and connection object DC1 located on the D side of the door body. Wiring W is configured to include power lines for supplying power and communication lines for communication. For example, wiring W is laid between the vehicle body B and the door body D, connecting connection object BC1 on the B side of the vehicle body, including connectors and equipment, to connection object DC1 on the D side of the door body, including connectors and equipment.

[0042] The main linkage mechanism 10, together with the secondary linkage mechanism 20, supports the door body D so that it can slide relative to the vehicle body B. The main linkage mechanism 10 is configured to include a main linkage arm 11, a first connecting part 12, and a second connecting part 13.

[0043] The main linkage arm 11 is a component that supports the door body D so that it can slide relative to the vehicle body B. The main linkage arm 11 includes a first arm 11a and a second arm 11b.

[0044] The first arm 11a is a metal component that extends along the extension direction X and is formed into a long strip. The first arm 11a is, for example, formed with a curved portion that bends from the vehicle body B side towards the door body D side. However, the first arm 11a is not limited to such a curved shape as long as it can support the door body D and allow it to slide relative to the vehicle body B. The first arm 11a includes a bottom portion 11h and a pair of sidewall portions 11i. The bottom portion 11h is the portion located on one side (lower side) in the height direction Z, and is formed into a long strip and a flat plate along the extension direction X. The pair of sidewall portions 11i are each formed into a long strip and a flat plate along the extension direction X, and are erected from both ends of the bottom portion 11h in the width direction Y along the height direction Z, and are arranged at fixed intervals along the width direction Y. The other side (upper side) of the bottom portion 11h of the first arm 11a in the height direction Z is open, and both ends in the extension direction X are closed. The first arm 11a thus constructed will accommodate the wiring W laid between the B side of the vehicle body and the D side of the door body in the groove 11d, which will be described later, formed by the bottom part 11h and a pair of side wall parts 11i.

[0045] The second arm 11b is configured the same as the first arm 11a described above. That is, the second arm 11b is a metal component that extends along the extension direction X and is formed into a long strip shape. The second arm 11b is, for example, formed with a curved portion that bends from the vehicle body B side to the door body D side. However, the second arm 11b is not limited to such a curved shape as long as it can support the door body D and allow it to slide relative to the vehicle body B. The second arm 11b is arranged side by side with the first arm 11a along the height direction Z. The second arm 11b is configured to include a bottom portion 11m and a pair of sidewall portions 11n. The bottom portion 11m is the portion located on one side (the lower side) in the height direction Z, and is formed into a long strip and a flat plate along the extension direction X. The pair of sidewall portions 11n are each formed into a long strip and a flat plate along the extension direction X, and are erected from both ends of the bottom portion 11m in the width direction Y along the height direction Z, and are arranged at fixed intervals along the width direction Y. The second arm 11b has an opening on the other side (upper side) of the bottom part 11m in the height direction Z, and the two ends in the extension direction X are closed. The second arm 11b configured in this way can accommodate the wiring W laid between the vehicle body B side and the door body D side in the groove 11e, which will be described later, formed by the bottom part 11m and a pair of side wall parts 11n.

[0046] Next, the first connecting part 12 will be explained. For example... Figure 2 As shown, the first connecting part 12 connects one end of the main connecting rod arm 11 in the extension direction X to the vehicle body B in a rotatable manner, and is configured to include a rotating shaft part 12a and a bearing part 12b.

[0047] The rotating shaft portion 12a supports one end of the main connecting rod arm 11 in the X-direction of its extension direction in a rotatable manner. The rotating shaft portion 12a is rod-shaped, extends along the Z-direction of its height, and is inserted into a hole (cylindrical hole) at one end of the main connecting rod arm 11 in the X-direction of its extension direction. Specifically, the rotating shaft portion 12a is inserted into holes at one end of the first arm 11a and one end of the second arm 11b in the X-direction of its extension direction in the main connecting rod arm 11. The rotating shaft portion 12a is provided with a stop (not shown) for maintaining a fixed distance between the first arm 11a and the second arm 11b in the Z-direction of its height. This stop prevents the first arm 11a and the second arm 11b from shifting position in the Z-direction of its height. The rotating shaft portion 12a, extending along the Z-direction of its height, supports one end of the first arm 11a and one end of the second arm 11b in a manner that allows rotation about the rotating shaft portion 12a. Alternatively, the structure that prevents the first arm 11a and the second arm 11b from shifting positions can be any structure other than the stop mentioned above.

[0048] The bearing portion 12b connects the rotating shaft portion 12a to the vehicle body B. The bearing portion 12b is configured to include a fixing plate 12c and a pair of support plates 12d.

[0049] The mounting plate 12c is a part that is fixed to the vehicle body B. The mounting plate 12c is formed in the shape of a flat plate, extends along the height direction Z, and is fixed to the vehicle body B.

[0050] A pair of support plates 12d support the rotating shaft portion 12a. The pair of support plates 12d are each formed as a flat plate, erected from both ends of the fixed plate 12c in the height direction Z along the width direction Y, and arranged at fixed intervals along the height direction Z. The rotating shaft portion 12a is disposed between one support plate 12d and the other support plate 12d. Each pair of support plates 12d has a hole for the rotating shaft portion 12a to pass through; one end of the rotating shaft portion 12a passes through the hole of one support plate 12d, and the other end passes through the hole of the other support plate 12d. Anti-detachment portions are provided at both ends of the rotating shaft portion 12a through which the pair of support plates 12d pass. With the bearing portion 12b configured as described above supporting both ends of the rotating shaft portion 12a inserted into the first arm 11a and the second arm 11b by the pair of support plates 12d, the fixed plate 12c is fixed to the vehicle body B.

[0051] Next, the second connecting part 13 will be explained. For example... Figure 2 As shown, the second connecting part 13 connects the other end of the main connecting rod arm 11 in the extension direction X to the door body D in a rotatable manner, and is configured the same as the first connecting part 12. That is, the second connecting part 13 is configured to include a rotating shaft part 13a and a bearing part 13b.

[0052] The rotating shaft portion 13a supports the other end of the main connecting rod arm 11 in the extension direction X in a rotatable manner. The rotating shaft portion 13a is rod-shaped, extends along the height direction Z, and is inserted into a hole (cylindrical hole) at the other end of the main connecting rod arm 11 in the extension direction X. Specifically, the rotating shaft portion 13a is inserted into holes in the main connecting rod arm 11 at the other end of the extension direction X of the first arm 11a and the other end of the extension direction X of the second arm 11b. The rotating shaft portion 13a is provided with a stop (not shown) for maintaining a fixed distance between the first arm 11a and the second arm 11b in the height direction Z. This stop prevents the first arm 11a and the second arm 11b from shifting position in the height direction Z. The rotating shaft portion 13a, extending along the height direction Z, supports the other end of the first arm 11a and the other end of the second arm 11b in a manner that allows rotation about the rotating shaft portion 13a. Alternatively, the structure that prevents the first arm 11a and the second arm 11b from shifting positions can be any structure other than the stop mentioned above.

[0053] The bearing section 13b connects the rotating shaft section 13a to the door body D. The bearing section 13b is configured to include a fixing plate 13c and a pair of support plates 13d.

[0054] The fixing plate 13c is the part that is fixed to the door body D. The fixing plate 13c is formed in the shape of a flat plate, extends along the height direction Z, and is fixed to the door body D.

[0055] A pair of support plates 13d support the rotating shaft portion 13a. The pair of support plates 13d are each formed as a flat plate, erected from both ends of the fixed plate 13c in the height direction Z along the width direction Y, and arranged at fixed intervals along the height direction Z. The rotating shaft portion 13a is disposed between one support plate 13d and the other support plate 13d. Each pair of support plates 13d has a hole through which the rotating shaft portion 13a is inserted; one end of the rotating shaft portion 13a is inserted into the hole of one support plate 13d, and the other end of the rotating shaft portion 13a is inserted into the hole of the other support plate 13d. The rotating shaft portion 13a inserted into the pair of support plates 13d has anti-detachment portions at both ends. With the bearing portion 13b configured as described above supporting the two ends of the rotating shaft portion 13a inserted into the first arm 11a and the second arm 11b by the pair of support plates 13d, the fixed plate 13c is fixed to the door body D.

[0056] The main linkage arm 11, configured as described above, can rotate relative to the vehicle body B and the door body D respectively, and together with the secondary linkage mechanism 20, supports the door body D so that it can slide relative to the vehicle body B along the sliding direction S.

[0057] Next, the secondary linkage mechanism 20 will be described. The secondary linkage mechanism 20 is arranged side-by-side with the main linkage mechanism 10 along the height direction Z. In this example, it is located below the main linkage mechanism 10 in the height direction Z, and together with the main linkage mechanism 10, it supports the door body D so that it can slide relative to the vehicle body B. The secondary linkage mechanism 20 is configured to include a secondary linkage arm 21, a first connecting portion 22, and a second connecting portion 23.

[0058] The secondary connecting rod arm 21 is arranged side by side with the main connecting rod arm 11 along the height direction Z, such as... Figure 3 As shown, it is configured to include a first arm 21a.

[0059] The first arm 21a is a metal component that extends along the extension direction X and is formed into a long strip. The first arm 21a may be formed in a straight line along the extension direction X, for example. However, the first arm 21a is not limited to such a straight line shape as long as it can support the door body D and allow it to slide relative to the vehicle body B. The first arm 21a is configured to include a bottom portion 21c and a pair of side wall portions 21d. The bottom portion 21c is the portion located on one side (lower side) in the height direction Z, and is formed into a long strip and a flat plate along the extension direction X. The pair of side wall portions 21d are each formed into a long strip and a flat plate along the extension direction X, and are erected from both ends of the bottom portion 21c in the width direction Y along the height direction Z, and are arranged at fixed intervals along the width direction Y. The other side (upper side) of the bottom portion 21c of the first arm 21a in the height direction Z is open, and both ends in the extension direction X are closed. The first arm 21a configured in this way can accommodate the wiring W laid between the B side of the vehicle body and the D side of the door body in the groove 21b, which will be described later, formed by the bottom part 21c and a pair of side wall parts 21d.

[0060] Next, the first connecting part 22 will be explained. For example... Figure 3 As shown, the first connecting part 22 connects one end of the secondary connecting rod arm 21 in the extension direction X to the vehicle body B in a rotatable manner, and is configured to include a rotating shaft part 22a and a bearing part 22b.

[0061] The rotating shaft portion 22a supports one end of the secondary connecting rod arm 21 in the X-direction of its extension direction in a rotatable manner. The rotating shaft portion 22a is rod-shaped, extends along the Z-direction of its height, and is inserted into a hole (cylindrical hole) at one end of the secondary connecting rod arm 21 in the X-direction of its extension direction. Specifically, the rotating shaft portion 22a is inserted into a hole in the secondary connecting rod arm 21 at one end of the first arm 21a in the X-direction of its extension direction. The rotating shaft portion 22a, extending along the Z-direction of its height, supports one end of the first arm 21a in a manner that allows it to rotate about the rotating shaft portion 22a.

[0062] The bearing section 22b connects the rotating shaft section 22a to the vehicle body B. The bearing section 22b is configured to include a fixed plate 22c and a pair of support plates 22d.

[0063] The mounting plate 22c is the part that is fixed to the vehicle body B. The mounting plate 22c is formed in the shape of a flat plate, extends along the height direction Z, and is fixed to the vehicle body B.

[0064] A pair of support plates 22d support the rotating shaft portion 22a. The pair of support plates 22d are each formed as a flat plate, erected from both ends of the fixed plate 22c in the height direction Z along the width direction Y, and arranged at fixed intervals along the height direction Z. The rotating shaft portion 22a is disposed between one support plate 22d and the other support plate 22d. Each pair of support plates 22d has a hole through which the rotating shaft portion 22a is inserted; one end of the rotating shaft portion 22a is inserted into the hole of one support plate 22d, and the other end of the rotating shaft portion 22a is inserted into the hole of the other support plate 22d. Anti-detachment portions are provided at both ends of the rotating shaft portion 22a through which the pair of support plates 22d are inserted. With the bearing portion 22b configured as described above supporting both ends of the rotating shaft portion 22a inserted into the first arm 21a by the pair of support plates 22d, the fixed plate 22c is fixed to the vehicle body B.

[0065] Next, the second connecting part 23 will be explained. For example... Figure 3 As shown, the second connecting part 23 rotatably connects the other end of the extension direction X of the secondary connecting rod arm 21 to the door body D, and is configured the same as the first connecting part 22. That is, the second connecting part 23 is configured to include a rotating shaft part 23a and a bearing part 23b.

[0066] The rotating shaft portion 23a supports the other end of the secondary connecting rod arm 21 in the X-direction of its extension direction in a rotatable manner. The rotating shaft portion 23a is rod-shaped, extends along the height direction Z, and is inserted into a hole (cylindrical hole) at the other end of the secondary connecting rod arm 21 in the X-direction of its extension direction. Specifically, the rotating shaft portion 23a is inserted into a hole in the secondary connecting rod arm 21 at the other end of the first arm 21a in the X-direction of its extension direction. The rotating shaft portion 23a, extending along the height direction Z, supports the other end of the first arm 21a in a manner that allows it to rotate around the rotating shaft portion 23a.

[0067] The bearing section 23b connects the rotating shaft section 23a to the door body D. The bearing section 23b is configured to include a fixing plate 23c and a pair of support plates 23d.

[0068] The fixing plate 23c is the part that is fixed to the door body D. The fixing plate 23c is formed in the shape of a flat plate, extends along the height direction Z, and is fixed to the door body D.

[0069] A pair of support plates 23d support the rotating shaft portion 23a. The pair of support plates 23d are each formed as a flat plate, erected from both ends of the fixed plate 23c in the height direction Z along the width direction Y, and arranged at fixed intervals along the height direction Z. The rotating shaft portion 23a is disposed between one support plate 23d and the other support plate 23d. Each pair of support plates 23d has a hole for the rotating shaft portion 23a to be inserted through; one end of the rotating shaft portion 23a is inserted through the hole of one support plate 23d, and the other end is inserted through the hole of the other support plate 23d. The rotating shaft portion 23a inserted into the pair of support plates 23d has anti-detachment portions at both ends. With the bearing portion 23b configured as described above supporting both ends of the rotating shaft portion 23a inserted into the first arm 21a by the pair of support plates 23d, the fixed plate 23c is fixed to the door body D.

[0070] The secondary linkage arm 21, configured as described above, can rotate relative to the vehicle body B and the door body D respectively, and together with the main linkage arm 11, supports the door body D so that it can slide relative to the vehicle body B.

[0071] The wiring harness layout structure 1, which is used to lay the wiring W in the linkage sliding door SD as described above, includes: slots 11d and 11e provided in the main linkage arm 11; slot 21b provided in the secondary linkage arm 21; cover 30; and binding member 40.

[0072] The groove 11d is disposed in the first arm 11a of the main connecting rod arm 11, and is the area formed by the bottom part 11h of the first arm 11a and a pair of sidewall parts 11i. The groove 11d is formed in a groove shape along the extending direction X in the first arm 11a, and the cross-section of the groove 11d is formed in a rectangular shape (see reference). Figure 5 The groove 11d has a receiving space that can accommodate the wiring W. The wiring W, which is laid along the first arm 11a between the vehicle body B side and the door body D side, can be accommodated in the receiving space. In this example, an example is shown in which the wiring W is actually accommodated in the receiving space.

[0073] The groove 11e is disposed in the second arm 11b of the main connecting rod arm 11, and is the area formed by the bottom portion 11m of the second arm 11b and a pair of sidewall portions 11n. The groove 11e is formed in a groove shape along the extending direction X in the second arm 11b, and the cross-section of the groove 11e is formed in a rectangular shape (see reference). Figure 5 The groove 11e has a receiving space that can accommodate the wiring W. The wiring W, which is laid along the second arm 11b between the vehicle body B side and the door body D side, can be accommodated in the receiving space. In this example, an example is shown in which the wiring W is not accommodated in the receiving space.

[0074] The groove 21b is provided in the first arm 21a of the secondary connecting rod arm 21, and is a region formed by the bottom part 21c of the first arm 21a and a pair of side wall parts 21d. The groove 21b is formed in a groove shape along the extending direction X in the first arm 21a, and the cross-section of the groove 21b is rectangular. The groove 21b has a receiving space capable of accommodating the wiring W. The wiring W laid along the first arm 21a between the vehicle body B side and the door body D side can be accommodated in the receiving space. In this example, an example is shown where the wiring W is not accommodated in the receiving space.

[0075] Next, the cover portion 30 will be described. The cover portion 30, for example, closes the opening of the slot portion 11d of the main connecting rod arm 11, such as... Figure 4 As shown, it is configured to include a closing part 31 and a holding part 32.

[0076] The closing portion 31 closes the opening of the groove 11d. It is formed in a long strip and flat shape along the extending direction X, and is slightly larger than the opening of the groove 11d. The closing portion 31 closes the opening of the groove 11d by covering it along the height direction Z. For example, the closing portion 31 closes the remaining portion of the opening of the groove 11d when the portion for leading the wiring W contained in the groove 11d outward, i.e., a part of the opening of the groove 11d, is open. That is, the closing portion 31 does not close the portion for leading the wiring W in the groove 11d outward. Specifically, the closing portion 31 closes the remaining portion of the opening of the groove 11d when the portion for leading the wiring W in the groove 11d to the vehicle body B side on one side of the extending direction X of the groove 11d and the portion for leading the wiring W in the groove 11d to the door body D side on the other side of the extending direction X of the groove 11d are open.

[0077] The retaining part 32 retains the wiring W and has a pair of wall parts 32a (see reference). Figure 5 A pair of wall portions 32a are each formed in an elongated and flat shape along the extending direction X. They are erected from both sides of the closing portion 31 of the cover portion 30 in the width direction Y and along the height direction Z toward the groove portion 11d, and are arranged at a fixed interval along the width direction Y. The interval between the wall portions 32a on one side and the wall portions 32a on the other side in the width direction Y is less than or equal to the diameter of the wiring W. The pair of wall portions 32a hold the wiring W by clamping it between the wall portions 32a on one side and the wall portions 32a on the other side.

[0078] Next, the bundling component 40 will be described. The bundling component 40 is a component that bundles and secures the wiring W to the cover portion 30. For example... Figure 5As shown, the binding member 40 is formed in the shape of a strip and is inserted into a hole provided on the closing portion 31 side of the holding portion 32 along the width direction Y. Furthermore, the binding member 40 is inserted into the gap between the wire W held by the holding portion 32 and the closing portion 31, and the holding portion 32 and the wire W are bound together by the inserted binding member 40, thereby fixing the wire W to the holding portion 32. The binding member 40 is provided at two locations at certain intervals along the extending direction X of the cover portion 30, fixing the wire W to the holding portion 32 on one side and the other side of the extending direction X of the cover portion 30.

[0079] The wiring harness WH, as described above, comprises wiring W, a cover 30, and a binding member 40. For example, with the wiring W, cover 30, and binding member 40 assembled together, the wiring harness WH is assembled into the slot 11d of the main link arm 11 of the vehicle body B, and is distributed throughout the vehicle body B and the door body D. This improves the assemblability of the wiring harness WH to the vehicle body B. Specifically, the cover 30 is assembled into the slot 11d of the first arm 11a while the wiring W is held by the holding part 32 and fixed to the holding part 32 by the binding member 40. At this time, the cover 30 is fixed to the slot 11d, for example, by locking the locking part (not shown) provided in the cover 30 into the locking part (not shown) provided in the slot 11d. Furthermore, the wiring W is accommodated in the receiving space of the groove 11d of the first arm 11a, and is laid along the first arm 11a with the opening of the groove 11d closed by the cover 30, so as to electrically connect the connection object BC1 on the B side of the vehicle body and the connection object DC1 on the D side of the door body.

[0080] The wiring harness layout structure 1, configured as described above, rotates the main linkage arm 11 via a drive unit (not shown) including a motor, etc., installed on the vehicle body B. The drive unit is connected to the rotation shaft of the main linkage arm 11 via a gear, etc., that transmits rotational force. By rotating this rotation shaft, the main linkage arm 11 rotates. The wiring harness layout structure 1 uses the drive unit to rotate the main linkage arm 11, causing the main linkage arm 11 and the secondary linkage arm 21 to rotate relative to the vehicle body B and the door body D, respectively. This causes the door body D to slide relative to the vehicle body B from a fully closed position along the sliding direction S to a fully open position, or from a fully open position along the sliding direction S to a fully closed position. In other words, the main linkage arm 11, by being rotated by the drive unit, rotates relative to the vehicle body B and the door body D, respectively, with the rotation shaft portion 12a of the first connecting portion 12 and the rotation shaft portion 13a of the second connecting portion 13 as its rotation axes. At this time, since the main linkage arm 11 rotates using the drive unit, the secondary linkage arm 21 rotates relative to the vehicle body B and the door body D, respectively, with the rotation axis 22a of the first connection 22 and the rotation axis 23a of the second connection 23 as the rotation axis. Moreover, during the rotation of the main linkage arm 11, the wiring W, which is laid along the main linkage arm 11 and housed in the receiving space of the slot 11d, also electrically connects the connection object BC1 on the vehicle body B side and the connection object DC1 on the door body D side.

[0081] As described above, the wiring harness layout structure 1 according to the embodiment includes at least a main connecting arm 11 and wiring W. One end of the main connecting arm 11 is rotatably connected to the vehicle body B, and the other end of the main connecting arm 11 is rotatably connected to the door body D. The main connecting arm 11 can rotate relative to both the vehicle body B and the door body D, and supports the door body D so that it can slide relative to the vehicle body B. The wiring W is laid along the main connecting arm 11, connecting the connection object on the vehicle body B side to the connection object on the door body D side. Moreover, the main connecting arm 11 includes a groove 11d, which is formed in a groove shape along the extending direction X of the main connecting arm 11 and can accommodate the wiring W.

[0082] According to this structure, the wiring harness routing structure 1 can ensure sufficient space for routing the wiring harness W between the vehicle body B and the door body D through the slot 11d of the main connecting arm 11. Furthermore, by accommodating the wiring harness W between the vehicle body B and the door body D within the slot 11d of the main connecting arm 11, the wiring harness routing structure 1 can prevent the wiring harness W from being exposed to the outside, thus reducing the risk of the wiring harness W getting snagged compared to conventional cases where the wiring harness W is exposed to the outside. As a result, the wiring harness routing structure 1 can properly route the wiring harness W between the vehicle body B and the door body D.

[0083] The wiring harness arrangement structure 1 also includes a cover 30 that closes the opening on the Z side of the groove 11d, which intersects the extension direction X. According to this structure, with the wiring W housed in the groove 11d of the main connecting arm 11, the cover 30 closes the opening of the groove 11d, thus protecting the wiring W. Furthermore, the cover 30 allows the wiring W to be externally concealed, resulting in a more aesthetically pleasing appearance. Additionally, by designing the cover 30 for the main connecting arm 11, the separate design of the main connecting arm 11 can be omitted.

[0084] In the wire harness routing structure 1, the cover 30 is configured to include: a closing portion 31 that closes the opening of the slot 11d; and a holding portion 32 that is provided in the closing portion 31 and holds the wiring W. According to this structure, by assembling the cover 30, which holds the wiring W using the holding portion 32, into the slot 11d of the main connecting rod arm 11, the wire harness routing structure 1 can accommodate the wiring W in the slot 11d and route it. That is, the wire harness routing structure 1 can simultaneously perform the operation of closing the opening of the slot 11d and the operation of accommodating the wiring W in the slot 11d and routing it.

[0085] The wiring harness layout structure 1 also includes a strapping member 40 formed in the shape of a strip, which straps the cover 30 and the wiring W and fixes the wiring W to the cover 30. According to this structure, even after the wiring W is accommodated in the groove 11d and laid out, the wiring harness layout structure 1 can maintain the state of fixing the wiring W to the cover 30, and can suppress the wiring W from shaking in the groove 11d due to vibrations generated when the door body D is opened and closed.

[0086] The linkage-type sliding door SD includes a door body D assembled to the vehicle body B, a main linkage arm 11, and wiring W. The main linkage arm 11 is configured to include a groove 11d, which is formed in a groove shape along the extending direction X of the main linkage arm 11 and is capable of accommodating the wiring W. According to this structure, the linkage-type sliding door SD can ensure the wiring W is laid between the vehicle body B and the door body D through the groove 11d of the main linkage arm 11, and the wiring W can be properly laid between the vehicle body B and the door body D.

[0087] The wiring harness WH has wiring W, which is laid along the main link arm 11 to connect the connection object BC1 on the B side of the vehicle body to the connection object DC1 on the D side of the door body, and is accommodated in the groove 11d of the main link arm 11, which is formed into a groove along the extending direction X. According to this structure, by accommodating the wiring W in the groove 11d of the main link arm 11, the wiring harness WH can be properly laid between the vehicle body B and the door body D.
