[0034] [Description of embodiments of this disclosure]

[0035] First, embodiments of this disclosure will be described.

[0036] The wiring structure of the wire harness disclosed herein is as follows.

[0037] (1) A wiring structure for a wire harness that connects a device disposed on a vehicle body to a device disposed on a sliding structure, wherein the wiring structure comprises: a wire harness including a first section, a second section, and a movable section, the first section being supported on the vehicle body, the second section being supported on the sliding structure, and the movable section being located between the first section and the second section; and a support member that supports the second section on the sliding structure, the support member comprising: a protective member for receiving the second section; and an arm capable of rotating about an axis. The arm is supported by the protective member for rotation; and a force-applying member applies force to the arm, the arm having: a shaft having the rotation axis; a holding portion holding the second section; a connecting portion connecting the shaft portion and the holding portion and extending radially; and a pressing portion extending from the shaft portion in a direction different from the connecting portion and pressing the portion of the second section closer to the floating section than the holding portion, the force-applying member applying force to the arm about the rotation axis in a direction that houses the portion closer to the floating section than the holding portion within the protective member.

[0038] According to the wiring structure of the wire harness in (1), since the arm has a holding part and a pressing part, when the arm rotates, the part held by the holding part and the part pressed by the pressing part in the second section can easily maintain a fixed radius of curvature. As a result, the pulling out and receiving of the wire harness in the sliding structure can be carried out as smoothly as possible.

[0039] (2) In the wiring structure of the wire harness in (1), the second section may include: a holding portion held by the holding portion; an end portion of the second section; and an extension portion located between the holding portion and the end portion, wherein the connecting portion covers the extension portion in such a way that the extension portion can move in the extension direction. Thus, the extension portion can move within the connecting portion, thereby increasing the wire harness capacity within the protective member while ensuring that the wire harness is pulled out and stored as smoothly as possible.

[0040] (3) In the wiring structure of the wire harness in (2), the pressing part may cover the extension part in such a way that the extension part can move in the extension direction. Thus, the extension part can move in the pressing part, thereby increasing the capacity of the wire harness within the protective member while making the pulling out and receiving of the wire harness as smooth as possible.

[0041] (4) In the wiring structure of any one of (1) to (3), the connecting portion and the pressing portion may be continuous along the circumferential direction of the axis. Thus, in the area continuous with the connecting portion, the pressing portion can press the wire harness.

[0042] (5) In the wiring structure of any one of (1) to (3), the connecting portion and the pressing portion may be separated from each other circumferentially along the axis. Thus, the pressing portion can press the wire harness at a position separated from the connecting portion, while reducing the size of the arm.

[0043] (6) In the wiring structure of any one of (1) to (5), the wiring harness may include: a wiring component; a first outer component externally mounted to the wiring component at an end of the second section closer to the portion held by the retaining part; and a second outer component externally mounted to the wiring component at a portion of the vehicle body closer to the portion held by the retaining part, wherein the first outer component is more flexible than the second outer component. Thus, even if the wiring harness within the protective member has an outer component, it can be smoothly bent during pull-out and retraction.

[0044] (7) In the wiring structure of any one of (1) to (6), the wiring harness may include: a wiring component; and an outer component externally mounted on the wiring component in the portion from the moving section to the retaining portion, the retaining portion holding the outer component in a manner rotatable about an axis along the extending direction. When the sliding structure moves, a torsional force may be applied to the outer component in the moving section. By holding the outer component in a manner rotatable about an axis along the extending direction by the retaining portion, the outer component is less prone to torsion.

[0045] (8) In the wiring structure of the wire harness in (7), the outer component may have: a bellows; and a clamping member externally mounted on the bellows, wherein the retaining portion holds the clamping member in a manner rotatable about the axis along the extension direction, and the clamping member rotates integrally with the bellows about the axis along the extension direction. Thus, compared to the case where the retaining portion holds the bellows in a rotatable manner, the outer component can rotate smoothly about the axis along the extension direction.

[0046] (9) In the wiring structure of any one of (1) to (8), the wire harness may include a first end on the first interval side and a second end on the second interval side, the second end being located outside the protective member, the wire harness including: a protective member fixing portion, fixed to the protective member between the portion held by the retaining portion and the second end; and a second end-side extension portion, extending from the protective member from the protective member fixing portion and close to the second end. Thus, when the wire harness is pulled out and received, the change in length of the second end-side extension portion can be suppressed.

[0047] (10) In the wiring structure of any one of (1) to (8), the wiring harness may include a first end on the first interval side and a second end on the second interval side, the second end being fixed to the protective member. Thus, in the sliding structure, by configuring the protective member, most of the wiring harness can be routed within the sliding structure.

[0048] (11) In the wiring structure of any of (1) to (10), the force-applying member may be a torsion spring or a helical spring. Thus, the force-applying member can be easily set up.

[0049] [Details of the embodiments of this disclosure]

[0050] Hereinafter, specific examples of the wiring structure of the wire harness of this disclosure will be described with reference to the accompanying drawings. Furthermore, this disclosure is not limited to these examples, but is shown in the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0051] [Implementation Method 1]

[0052] The wiring structure of the wiring harness in Embodiment 1 will be described below. The wiring structure of the wiring harness is the wiring structure that connects the equipment installed on the vehicle body to the equipment installed on the sliding structure. In this embodiment, an example of a sliding door as the sliding structure will be described. The sliding structure may also be a component other than a sliding door, such as a sliding seat.

[0053] Figure 1 This is a schematic top view showing the wiring structure 20 of the wire harness in Embodiment 1. Figure 1 The front and rear directions (front and rear) shown correspond to the front and rear directions of the vehicle. Figure 1 The inward and outward directions (inward and outward) shown correspond to the inward and outward directions relative to the side of the vehicle in the left-right direction. Specifically, Figure 1 The image shows the left side of the vehicle. The area to the right (bottom of the paper) of the left side of the vehicle is the inner side, and the area to the left (top of the paper) of the left side is the outer side. (The following will be discussed further.) Figure 5 The up and down directions shown correspond to the up and down directions of the vehicle.

[0054] First, the wiring harness structure 20 and the relationship between the wiring harness structure 20 and the vehicle body 10 and sliding door 12 to which it is applied will be explained. Furthermore, in Figure 1 In the diagram, the wiring structure 20 of the wire harness shown in solid lines represents the open state of the sliding door 12, while the wiring structure 20 of the wire harness shown in double-dotted lines represents the closed state of the sliding door 12. Additionally, in... Figure 1 In the diagram, some components, such as the sliding door 12, are shown with double-dotted lines regardless of whether they are in the open or closed state.

[0055] An opening 11 for passengers to board and alight is provided on the side of the vehicle body 10. A sliding door 12 is supported on the vehicle body 10 in a slidable manner. The opening 11 is opened and closed by sliding the sliding door 12. The sliding door 12 includes a door panel 13, which forms the exterior of the sliding door 12; and a door interior panel 14, which is disposed on the interior side of the door panel 13. For example, the door arm 15 supporting the sliding door 12 is supported in a slidable manner on a support rail disposed on the vehicle body 10. A sealing strip 16 is disposed around the periphery of the opening 11 in a manner that contacts the door panel 13 and the vehicle body 10. For example, the sealing strip 16 is disposed in a ring shape on the outer periphery of the door interior panel 14 when the sliding door 12 is closed.

[0056] A door-side device, such as a power window, is provided on the sliding door 12. This door-side device is connected to a body-side device (such as an ECU) provided on the vehicle body 10 via a wiring harness 30. The wiring harness 30 is routed across the vehicle body 10 and the sliding door 12. The wiring structure 20 of the wiring harness includes: the wiring harness 30, connecting the body-side device and the door-side device; a support member 40, supporting the wiring harness 30 on the sliding door 12; and a body support member 70, supporting the wiring harness 30 on the vehicle body 10.

[0057] The wiring harness 30 includes: a wiring component 31 for transmitting power or signals between door-side equipment and vehicle-side equipment; and an external component mounted on the wiring component 31. The wiring component 31 may be, for example, an electrical wire or optical fiber. The wiring component 31 can be a single component or multiple components. The external component protects the wiring component 31 or bundles multiple wiring components 31 together. Here, the external component includes a bellows 33. The bellows 33 has a shape with alternating continuous large-diameter cylindrical sections and small-diameter cylindrical sections, each with a circular cross-section. On the outer and inner surfaces of the bellows 33, the concave and convex shapes corresponding to the large-diameter and small-diameter cylindrical sections are continuous along the extending direction. Furthermore, in... Figure 1 In the design, the ends of the bellows 33 are depicted according to the original shape of the bellows 33 with its concave and convex shapes, but the middle part of the bellows 33 is simplified and the concave and convex shapes are omitted. Figure 2 The same applies to the subsequent diagrams.

[0058] The wiring harness 30 includes: a first section 34 supported on the vehicle body 10; a second section 35 supported on the door; and a movable section 36 located between the first section 34 and the second section 35. The first section 34, the second section 35, and the movable section 36 are different from each other along the extension direction of the wiring harness 30.

[0059] The first section 34 is supported on the body 10 by a body support member 70. The first section 34 is held on the body 10 when the sliding door 12 is opened and closed. The first section 34 is, for example, positioned above the floor panel and covered by a carpet or floor mat to suppress exposure. For example, the body 10 is provided with a body-side wiring harness opening for leading the wiring harness 30 to the periphery of the passenger / passenger opening 11. Figure 1 The body support member 70 shown supports the portion of the first section 34 connected to the movable section 36 around the periphery of the opening for the wiring harness on the body side. The movable section 36 extends to the outside of the body 10 through the opening for the wiring harness on the body side.

[0060] The second section 35 is supported by the support member 40 on the sliding door 12. The second section 35 is held on the sliding door 12 and moves relative to the vehicle body 10 together with the sliding door 12 when the sliding door 12 is opened and closed. Here, a portion of the second section 35 is supported by the support member 40 so that it can move relative to the sliding door 12 along a fixed path when the sliding door 12 is opened and closed. The second section 35 is positioned between the door panel 13 and the door interior panel 14, thus preventing exposure. An opening for the door-side wiring harness 30 is provided on the door interior panel 14. The door-side wiring harness opening is, for example, located at the lower part of the door interior panel 14. The movable section 36 extends to the outside of the sliding door 12 through this door-side wiring harness opening.

[0061] The movable section 36 is not supported by the vehicle body 10 and the sliding door 12, and can move freely relative to the vehicle body 10 and the sliding door 12 compared to the first section 34 and the second section 35. The movable section 36 is stretched by the sliding door 12 when the sliding door 12 opens and closes, thereby moving and changing its posture relative to the vehicle body 10 and the sliding door 12. A bellows 33 is provided in the movable section 36. Here, assuming that the movable section 36 undergoes three-dimensional movement when the sliding door 12 opens and closes, the bellows 33 can follow the three-dimensional movement of the movable section 36. One end of the bellows 33 extends to the first section 34 and is supported by the vehicle body support member 70 on the vehicle body. The other end of the bellows 33 extends to the second section 35 and is supported by the sliding door 12 by the support member 40.

[0062] Here, the movable section 36 has an exposed section. The exposed section is the area between the vehicle body 10 and the sliding door 12 when the sliding door 12 is open. Here, the bellows 33 provided in the movable section 36 is exposed. For example, the exposed section is the part between the opening for the vehicle side wiring harness and the opening for the door side wiring harness in the movable section 36. Although the exposed section is exposed in a position such as behind and below the passenger boarding / alighting opening 11 that is as close as possible to avoid interference when passengers board and alight, it is still a part that may be stepped on by passengers.

[0063] Hereinafter, the closed state of sliding door 12 is defined as the closed state. The open state of sliding door 12 is defined as the open state. Sometimes, the state in which the exposed section is not stepped on and the moving section 36 is in a natural state in the open state is referred to as the first open state. In addition, sometimes, a load F that would be applied to the exposed section when stepped on (refer to...) is applied in the open state. Figure 6 The state of ) is called the second open state.

[0064] A more detailed description is given of each part of the wiring structure 20 of the wire harness. Figure 2 This is a front view showing the wiring structure 20 of the wire harness in Embodiment 1. Figure 3 This is an exploded perspective view showing the support member 40 of Embodiment 1. Furthermore, in Figure 3 In the diagram, the cover 43 shown by the imaginary line indicates a state in which it is installed in the correct orientation relative to the main body 42, while the cover 43 shown by the solid line indicates a state in which it has been rotated 180 degrees from the state shown by the imaginary line. Figure 4 It is along Figure 3 A cross-sectional view along line IV-IV. Figure 5 and Figure 6 This is an explanatory diagram showing the deformation of the wire harness 30 as the sliding structure 12 moves. Figure 5 It's a 3D image. Figure 6 This is the main view. Figure 5 and Figure 6 The diagram shows the wiring structure 20 in each of the following states: closed (CS), intermediate (IS), and open (OS). Figure 5 and Figure 6 The intermediate state IS shown is, for example, the state in which the protective member 41 and the body support member 70 are in the same position in the front-rear direction.

[0065] The support member 40 includes a protective member 41, an arm 50, and a force-applying member 60. The protective member 41 houses the second section 35. The arm 50 is supported on the protective member 41 in a manner that allows it to rotate about a rotation axis. The force-applying member 60 applies force to the arm 50.

[0066] The wiring harness 30 includes: a first end located on the side of the first section 34; and a second end located on the side of the second section 35. A first connector 37 is provided at the first end, and a second connector 38 is provided at the second end. The second connector 38 is located outside the protective member 41. The second connector 38 is disposed within the sliding door 12 in a position separate from the protective member 41.

[0067] The second section 35 has a holding portion 35A, a first extension portion 35B, and a second extension portion 35C. The holding portion 35A is the portion held by the arm 50. The first extension portion 35B is the portion extending from the holding portion 35A toward the first end side. The second extension portion 35C is the portion extending from the holding portion 35A toward the second end side. The second extension portion 35C has an intermediate extension portion 35D and a second end side extension portion 35E. The intermediate extension portion 35D is the portion of the second extension portion 35C that is housed within the protective member 41. The second end side extension portion 35E is the portion of the second extension portion 35C that extends outside the protective member 41. The second section 35 extends from the holding portion 35A through the intermediate extension portion 35D and the second end side extension portion 35E to the second end 38.

[0068] The second section 35 has a loop portion 35L. The loop portion 35L is the portion where the wire harness 30 is wired in a loop shape. Here, the loop portion 35L is provided in the second extension portion 35C. Here, the loop portion 35L is provided in the middle extension portion 35D. At the end of the loop portion 35L, there is a cross portion 35I where the wire harness 30 crosses. The loop portion 35L is the portion that extends in a loop from one side where it overlaps at the cross portion 35I to the other side where it overlaps at the cross portion 35I.

[0069] The wire harness 30 may also include a protective member fixing portion, which is fixed to the protective member 41 between the ring portion 35L and the second end portion 38. For example, the wire harness 30 may be fixed to the protective member 41 at the insertion portion 47. The second end side extension portion 35E extends from the protective member 41 from the protective member fixing portion and approaches the second end portion 38.

[0070] The outer casing of the wiring harness 30 includes a fiber tube 32. The fiber tube 32 is a tubular component formed from a fibrous fabric such as knitted or woven fabric. The fiber tube 32 is an example of a first outer casing component mounted on the wiring harness 31 at the ring portion 35L. The corrugated tube 33 is an example of a second outer casing component mounted on the wiring harness 31 on the vehicle body side, closer to the ring portion 35L. Alternatively, the corrugated tube 33 is an example of an outer casing component mounted on the wiring harness 31 from the traveling section 36 to the holding portion 52. The first outer casing component may not be a fiber tube 32. For example, the first outer casing component may be adhesive tape.

[0071] The fiber tube 32, which serves as the first outer component, is more flexible than the bellows 33, which serves as the second outer component. Here, the ring portion 35L can be bent with a smaller radius of curvature than the floating range 36. By attaching the fiber tube 32, which is more flexible than the bellows 33, to the ring portion 35L, it is less likely to hinder the bending of the ring portion 35L.

[0072] In the wiring harness 30, the wiring member 31 is inserted into the bellows 33 in a manner that allows it to move along the extension direction. Therefore, the wiring member 31 is less susceptible to external forces applied to the bellows 33. Specifically, the wiring member 31 passes only through the interior of the bellows 33 and is not fixed to it. Therefore, even if the bellows 33 twists, the wiring harness 30 is less prone to twisting. Furthermore, when the bellows 33 is pressed at its middle portion in a direction intersecting the axial direction, it bends in a stretched manner along the pressed direction while the difference between the concave and convex portions decreases, resulting in elongation deformation. At this time, when the wiring member 31 is pressed by the bellows 33, it moves along the extension direction, thereby suppressing the increase in tension applied to the wiring member 31.

[0073] The wiring component 31 can also be fixed in a manner that prevents it from moving along the extension direction with the fiber optic tube 32. The wiring component 31 can be fixed together with the end of the fiber optic tube 32 by binding with binding components such as adhesive tape or cable ties.

[0074] The protective member 41 houses the second section 35. The protective member 41 houses the ring portion 35L. The protective member 41 consists of two parts: a main body 42 and a cover 43. The main body 42 and the cover 43 can be made of resin, for example. The main body 42 and the cover 43 can be injection molded, for example. The main body 42 and the cover 43 can be configured to maintain their combined state through a locking structure integrally formed with the main body 42 and the cover 43. Alternatively, the main body 42 and the cover 43 can be configured to maintain their combined state through a fastening structure using bolts or other fastening members. The main body 42 and the cover 43 each have a main plate portion 44, a peripheral wall portion 45, a bearing portion 46, and a spring support portion 48. The bearing portion 46 and the spring support portion 48 can exist in both the main body 42 and the cover 43, or only in one of them.

[0075] The main plate portion 44 is formed in the shape of a circular plate. The main plate portion 44 of the main body 42 covers the ring portion 35L from one axial side. The main plate portion 44 of the cover 43 covers the ring portion 35L from the other axial side.

[0076] The peripheral wall portion 45 protrudes axially from the outer periphery of the main board portion 44. The peripheral wall portion 45 is not provided along the entire circumference of the outer periphery of the main board portion 44. The peripheral wall portion 45 is provided on a portion of the main board portion 44 along the circumferential direction. Another portion of the main board portion 44 along the circumferential direction becomes an opening without the peripheral wall portion 45. The portion extending from the first extension portion 35B toward the moving section 36 extends through this opening to the outside of the protective member 41. Here, this opening is provided at the lower edge of the main board portion 44. Here, an area of ​​more than a quarter of the circumference is designated as the opening. As the sliding door 12 opens and closes, the position of the wiring harness 30 extending from the opening changes.

[0077] The bearing portion 46 supports the shaft portion 51 of the arm 50. Here, the shaft portion 51 is concave, and the bearing portion 46 is convex. The bearing portion 46 protrudes from the center of the inner surface of the main plate portion 44. Alternatively, the shaft portion 51 may be convex and the bearing portion 46 may be concave.

[0078] The spring support portion 48 supports one end of the force-applying member 60. Here, the spring support portion 48 has: a pair of wall portions protruding from the outer surface of the peripheral wall portion 45; and a support shaft connecting the pair of wall portions. One end of the force-applying member 60 is engaged with the support shaft.

[0079] The protective member 41 has a through portion 47. The through portion 47 is provided on the main body 42 or the cover 43. The through portion 47 protrudes into the inner surface of the main body portion 44. The through portion 47 is formed in the shape of a tunnel along the radial direction.

[0080] Arm 50 has a shaft portion 51, a retaining portion 52, a connecting portion 53, and a pressing portion 54. Arm 50 may be made of resin, for example. Arm 50 may be an injection-molded product, for example. Arm 50 may also be composed of multiple parts, like the main body 42 and cover 43 of the protective member 41. In particular, the retaining portion 52 and connecting portion 53, which are cylindrical or square, may also be composed of a groove-shaped component and a cover-shaped component, and can be installed on the wire harness 30 from the side.

[0081] The shaft portion 51 has a rotating shaft. The rotating shaft extends in a horizontal direction. The shaft portion 51 is located inside the ring portion 35L. The shaft portion 51 is formed into a cylindrical shape with openings at both ends. Through the openings at both ends, the bearing portion 46 of the main body 42 and the bearing portion 46 of the cover 43 are fitted into the shaft portion 51.

[0082] The retaining portion 52 retains the second section 35. The retaining portion 52 retains the portion of the second section 35 that extends along the outer side of the ring portion 35L. The retaining portion 52 retains the retained portion 35A. Here, the retaining portion 52 retains the bellows 33. The retaining portion 52 has a protrusion 52a and a recess 52b. The protrusion 52a engages with the recess 52b of the bellows 33, and the protrusion 52a of the bellows 33 engages with the recess 52b. Thus, the movement of the bellows 33 relative to the retaining portion 52 in the extending direction is restricted.

[0083] The retaining portion 52 can also hold the bellows 33 in a manner that allows it to rotate about an axis along the extension direction. For example, the protrusions 52a and recesses 52b can be formed to be smaller than the protrusions and recesses of the bellows 33, thereby allowing the bellows 33 to rotate about an axis along the extension direction within the retaining portion 52. Alternatively, for example, the retaining portion 52 can also hold the bellows 33 in a manner that allows it to rotate about an axis along the extension direction via a clamping member. In this case, the clamping member holds the bellows 33 in a manner that prevents it from rotating about an axis along the extension direction, and the retaining portion 52 holds the clamping member in a manner that allows it to rotate about an axis along the extension direction.

[0084] The retaining part 52 is located at the same height as or higher than the rotation axis. When the sliding door 12 opens and closes, the arm 50 rotates by 180 degrees or less, and the area at the same height as or higher than the shaft 51 is the moving area of ​​the retaining part 52. Furthermore, as long as a portion of the retaining part 52 is located higher than the lower end of the shaft 51, it can also be considered that the retaining part 52 is located at the same height as or higher than the rotation axis.

[0085] exist Figure 6 In the example shown, the retaining part 52 is at the same height as the rotation axis in the closed state CS and the intermediate state IS, and is located on opposite sides of the rotation axis. In the closed state CS, the retaining part 52 is located at the same position as the rotation axis or in a position slightly forward of the rotation axis. In the intermediate state IS, the retaining part 52 is located slightly backward of the rotation axis. The retaining part 52 moves within the region between the position in the closed state CS and the position in the intermediate state IS.

[0086] The connecting portion 53 connects the shaft portion 51 to the retaining portion 52. The connecting portion 53 extends radially from the shaft portion 51.

[0087] The pressing part 54 extends radially from the shaft part 51 in a direction different from the direction in which the connecting part 53 extends. The pressing part 54 presses the first extension part 35B in the second section 35.

[0088] Here, the pressing portion 54 is formed in a fan shape. The pressing portion 54 is wider than the connecting portion 53 in the circumferential direction. The pressing portion 54 is connected to the connecting portion 53 in the circumferential direction. The area of ​​the connecting portion 53 and the pressing portion 54 in the circumferential direction is greater than 90 degrees and less than 180 degrees. Here, the area of ​​the connecting portion 53 and the pressing portion 54 in the circumferential direction is about 130 degrees. The pressing portion 54 may also have a portion that presses the first extension portion 35B at a position that is separated from the connecting portion 53 by more than 90 degrees in the circumferential direction.

[0089] The pressing part 54 can be configured to always press the first extension portion 35B during opening and closing. The pressing part 54 can also be configured to press the first extension portion 35B in a partial state during opening and closing. For example, the pressing part 54 may be in the state where it moves the most in the direction in which force is applied to the holding part 52 (here,...). Figure 6 In the intermediate state (IS) shown, press the first extension portion 35B. In the open state (OS) or closed state (CS), the pressing part 54 may not need to press the first extension portion 35B.

[0090] exist Figure 6In the example shown, the portion of the pressing part 54 located circumferentially away from the connecting part 53 does not press the first extension portion 35B in the open state OS or the closed state CS. In the open state OS or the closed state CS, the peripheral wall portion 45 does not have a portion opposite to the portion of the pressing part 54 located circumferentially away from the connecting part 53. In the open state OS or the closed state CS, the first extension portion 35B extends from the end of the peripheral wall portion 45 between the end of the peripheral wall portion 45 and the circumferential middle portion of the pressing part 54 to the outside of the protective member 41 and away from the pressing part 54.

[0091] The connecting portion 53 and the pressing portion 54 cover the second extension portion 35C in such a way that the second extension portion 35C can move in the extension direction. At the portions where the connecting portion 53 and the pressing portion 54 intersect with the ring portion 35L, the ring portion 35L can move in the extension direction. The inner surfaces of the connecting portion 53 and the pressing portion 54 do not have the uneven shape found on the inner surface of the holding portion 52. Furthermore, the hollow portions of the connecting portion 53 and the pressing portion 54 are formed with a diameter larger than the diameter of the wiring member 31 in the ring portion 35L without clamping the wiring member 31.

[0092] Here, the connecting portion 53 and the pressing portion 54 are cylindrical or square-shaped, and a portion of the ring portion 35L passes through the connecting portion 53 and the pressing portion 54. The connecting portion 53 and the pressing portion 54 have: a pair of main wall portions covering the ring portion 35L from both axial sides; an inner peripheral wall portion covering the inner peripheral side of the ring portion 35L; and an outer peripheral wall portion covering the outer peripheral side of the ring portion 35L. One of the pair of main wall portions contacts the main plate portion 44 of the main body 42, and the other main wall portion is opposite to the main plate portion 44 of the cover 43. The outer surface of the shaft portion 51 constitutes the inner peripheral wall portion. The outer surface of the inner peripheral side of the retaining portion 52 constitutes the outer peripheral wall portion. The outer peripheral wall portion of the pressing portion 54 presses the first extension portion 35B so that the first extension portion 35B does not bend towards the inner peripheral side. The outer peripheral wall portion of the connecting portion 53 separates the internal space of the retaining portion 52 from the internal space of the connecting portion 53. Alternatively, one of the pair of main wall portions can be omitted, and the connecting portion 53 and the pressing portion 54 can be formed into a groove. In this case, one of the pair of main plate portions 44 becomes the cover of the groove.

[0093] Arm 50 has a spring support portion 55 and a guide groove 56. The spring support portion 55 supports one end of the force-applying member 60. The spring support portion 55 protrudes towards the outer periphery of the protective member 41. The spring support portion 55 is connected to the outer periphery of the retaining portion 52. The spring support portion 55 has a receiving portion and a support shaft. The receiving portion has a bottom wall and a pair of side walls, and is formed in a groove shape. The outer surface of the bottom wall is connected to the outer surface of the retaining portion 52. The support shaft is configured to connect the pair of side walls at one end of the receiving portion. A portion of the force-applying member 60 is housed in the receiving portion, and one end of the force-applying member 60 is engaged with the support shaft.

[0094] A guide groove 56 is provided between the spring support portion 55 and the retaining portion 52. The guide groove 56 is formed in the portion connecting the spring support portion 55 and the retaining portion 52. The end of the peripheral wall portion 45 is fitted into the guide groove 56. Thus, when the arm 50 rotates, the spring support portion 55 can move stably along the outer periphery of the protective member 41. Here, guide grooves 56 are formed on both axial sides of the arm 50. The peripheral wall portion 45 of the main body 42 and the peripheral wall portion 45 of the cover 43 are respectively fitted into the guide grooves 56.

[0095] The force-applying member 60 applies force to the arm 50 in a direction about the rotational axis, with the portion of the retaining part 52 closer to the floating section 36 housed within the protective member 41. The force-applying member 60 also applies force to the arm 50 in a direction about the rotational axis that increases the size of the ring portion 35L. The force-applying member 60 is a helical spring 60. The helical spring 60 includes a spring body 61 and hook portions 62 and 63 provided at both ends of the spring body 61. The spring body 61 is a coiled wire. The spring body 61 extends along the outer periphery of the protective member 41. A portion of the spring body 61 is housed in the receiving portion of the spring support portion 55 of the arm 50. The hook portion 62 is engaged with the support shaft of the spring support portion 55 of the arm 50 and is supported. The hook portion 63 is engaged with the support shaft of the spring support portion 48 of the protective member 41 and is supported. The hook portion 63 does not move even when the arm 50 rotates. The hook portion 62 moves circumferentially as the arm 50 rotates. Thus, the spring body 61 extends and retracts when the arm 50 rotates.

[0096] The force-applying component 60 can also apply force to the arm 50 in the same direction throughout the opening and closing of the sliding door 12. For example, even in the state of maximum excess length ( Figure 5 In the intermediate state (IS), the spring body 61 can also be in a state of being longer than its natural length.

[0097] When the sliding structure 12 slides relative to the vehicle body 10 between positions 1 and 2, the length of the sliding section 36 and the size of the ring 35L change. When the length of the sliding section 36 decreases, the size of the ring 35L increases. When the length of the sliding section 36 increases, the size of the ring 35L decreases. The size of the ring 35L can be considered as the length of the section housed in the protective member 41. Specifically, an increase in the size of the ring 35L is equivalent to an increase in the length of the section housed in the protective member 41 within the wiring harness 30, and a decrease in the size of the ring 35L is equivalent to a decrease in the length of the section housed in the protective member 41 within the wiring harness 30.

[0098] At the intermediate position between position 1 and position 2, the length of the moving interval 36 is the shortest, and the size of the loop 35L is the largest. At at least one of positions 1 and 2, the length of the moving interval 36 is the longest, and the size of the loop 35L is the smallest. Here, at position 1, the length of the moving interval 36 is the longest, and the size of the loop 35L is the smallest. At position 2, the length of the moving interval 36 is the length between the longest length at position 1 and the shortest length at the intermediate position, and the size of the loop 35L is the size between the smallest size at position 1 and the largest size at the intermediate position.

[0099] When the sliding structure 12 slides relative to the vehicle body 10 from the first position toward the middle position, the length of the moving section 36 becomes shorter and the size of the ring 35L becomes larger. When the sliding structure 12 slides relative to the vehicle body 10 from the middle position toward the second position, the length of the moving section 36 becomes longer and the size of the ring 35L becomes smaller.

[0100] When the sliding structure 12 slides relative to the vehicle body 10 from the second position toward the middle position, the length of the moving section 36 becomes shorter and the size of the ring 35L becomes larger. When the sliding structure 12 slides relative to the vehicle body 10 from the middle position toward the first position, the length of the moving section 36 becomes longer and the size of the ring 35L becomes smaller.

[0101] In the first open state, the retaining portion 52 of the arm 50 is in the intermediate position. Therefore, the arm 50 can rotate in the direction in which the wire harness 30 is pulled out from the protective member 41. In the first open state, when a load F is applied, the arm 50 rotates, and the wire harness 30 is pulled out from the protective member 41, thus entering the second open state. The position of the retaining portion 52 of the arm 50 in the second open state is the same as the position of the retaining portion 52 of the arm 50 in the closed state CS, or a position that is closer to the position of the retaining portion 52 of the arm 50 in the closed state than the position of the retaining portion 52 of the arm 50 in the first open state.

[0102] <Effects, etc.>

[0103] Based on the wiring structure 20 of the wire harness as described above, the arm 50 has a holding part 52 and a pressing part 54. When the arm 50 rotates, the portion pressed by the pressing part 54 and the portion between the holding part 35A in the second section 35 can easily maintain a fixed radius of curvature. As a result, the pulling out and receiving of the wire harness 30 in the sliding door 12 can be carried out as smoothly as possible.

[0104] Here, let's consider starting from... Figure 6The diagram shows the case where the intermediate state IS transitions to the closed state CS and the wire harness 30 is pulled out. In this case, a tensile force is applied to the wire harness 30, such that the first end 37 is stretched rearward. Additionally, a force-applying member 60 applies a force to the held portion 35A. If the tensile force is greater than the applied force, the arm 50 rotates, and the wire harness 30 is smoothly pulled out. However, if the applied force is greater than the tensile force, the arm 50 does not rotate, and the first extension portion 35B bends near the held portion 35A, making it possible to pull out the wire harness 30. In this case, the first extension portion 35B, bent near the held portion 35A, may interfere with the second extension portion 35C, making it difficult to pull out the wire harness 30.

[0105] In this respect, when the pressing part 54 is provided as disclosed herein, even if the applied force is greater than the tensile force, the bending position of the first extension portion 35B can be moved away from the holding portion 35A. This suppresses interference between the first extension portion 35B and the second extension portion 35C, allowing the wire harness 30 to be pulled out smoothly. Furthermore, in addition to the force on the holding portion 52 due to the stretching of the holding portion 35A, the force on the pressing part 54 from the portion abutting against the first extension portion 35B also becomes a force that causes the arm 50 to rotate against the force applied by the force-applying member 60. Therefore, the arm 50 easily rotates against the force applied by the force-applying member 60, allowing the wire harness 30 to be pulled out smoothly.

[0106] In addition, from Figure 6 When the wire harness 30 is accommodated during the transition from the open state OS or the closed state CS to the intermediate state IS, the first extension portion 35B is accommodated along the outer surface of the pressing portion 54. This suppresses interference between the first extension portion 35B and the second extension portion 35C, allowing the wire harness 30 to be accommodated smoothly.

[0107] Additionally, when the holding part 52 moves to a position higher than the rotation axis during the rotation of the arm 50, Figure 6 In the intermediate state IS shown, the portion of the first extension 35B located above the held portion 35A may sag. Even in this case, the sag of the first extension 35B can be suppressed by providing the pressing part 54. As a result, the pulling out and receiving of the wire harness 30 can be carried out smoothly.

[0108] Furthermore, the connecting portion 53 and the pressing portion 54 cover the second extension portion 35C in such a way that the second extension portion 35C can move in the extension direction. As a result, the second extension portion 35C can move in the connecting portion 53 and the pressing portion 54, thereby increasing the capacity of the wire harness 30 within the protective member 41 while making the pulling out and receiving of the wire harness 30 as smooth as possible.

[0109] Furthermore, the connecting portion 53 and the pressing portion 54 are connected circumferentially along the shaft portion 51. Thus, in the area continuous with the connecting portion 53, the pressing portion 54 can press the wire harness 30.

[0110] Furthermore, the fiber tube 32 externally mounted on the second extension portion 35C is more flexible than the corrugated tube 33 externally mounted on the first extension portion 35B to the moving section 36. Thus, even with the external component provided on the second extension portion 35C, the wire harness 30 can be bent smoothly during pull-out and retraction.

[0111] Furthermore, the retaining part 52 holds the bellows 33 in a manner that allows it to rotate about an axis along the extending direction. Here, when the sliding structure 12 slides, a torsional force may be applied to the bellows 33 at the moving section 36. By holding the bellows 33 in a manner that allows it to rotate about an axis along the extending direction, the bellows 33 is less prone to torsion.

[0112] Additionally, the wire harness 30 includes: a protective member fixing portion, which is fixed to the protective member 41 between the retained portion 35A and the second end portion 38; and a second end-side extension portion 35E, which extends from the protective member 41 from the protective member fixing portion and approaches the second end portion 38. Thus, when the wire harness 30 is pulled out and received, the length of the second end-side extension portion 35E can be suppressed from changing.

[0113] In addition, the force-applying component 60 is a helical spring 60. Therefore, the force-applying component 60 can be easily installed.

[0114] [Postscript]

[0115] Figure 7 This is a front view showing the wiring structure 120 of the wire harness in the first modified example.

[0116] In this modified example, the structure of the second section 135 of the wiring harness 130 differs from the structure of the second section 35 of the wiring harness 30 described above. Specifically, in the wiring harness 130, the second end-side extension 35E is omitted, and the second end 38 is fixed to the protective member 41. Thus, in the sliding door 12, by configuring the protective member 41, most of the wiring harness 130 is routed within the sliding door 12.

[0117] In this case, the protective element 41 may also include a connector support portion that supports the second connector 38. Additionally, in Figure 7 In the example shown, a trunk harness 180 connected to the second connector 38 is provided in the sliding door 12. The trunk harness 180 includes: a trunk connector 182 connected to the second connector 38; and a trunk wiring member 181 extending from the trunk connector 182. In the sliding door 12, the second connector 38, supported by the protective member 41, can also be directly connected to the connector of the device inside the sliding door 12.

[0118] Figure 8 This is a front view showing the wiring structure 220 of the wire harness in the second variation. Figure 9 This is an exploded perspective view showing the support member 240 of the second modified example.

[0119] In this modified example, the shape of the support member 240 differs from that of the support member 40 described above. In this modified example, the force-applying member 260 in the support member 240 is a torsion spring 260. In this case, similarly to the case of the coil spring 60, the force-applying member 260 can be easily installed.

[0120] The torsion spring 260 also includes a spring body 261 and hook portions 262 and 263 disposed at both ends of the spring body 261. The spring body 261 is formed of wire in a coil shape. The spring body 261 is coaxially arranged with the shaft portion 251. The diameter of the spring body 261 is larger than that of the shaft portion 251. The shaft portion 251 is disposed inside the spring body 261. The hook portion 262 extends the wire in a straight line from one end of the coil-shaped spring body 261. The hook portion 263 extends the wire in an L-shape from the other end of the coil-shaped spring body 261.

[0121] The arm 250 and the protective member 241 in the support member 240 have a structure corresponding to the torsion spring 260.

[0122] The shaft portion 251 of the arm 250 has: a hole 251A for the bearing portion 46 of the main body 242 of the protective member 241 to pass through; and a first annular groove 251B for receiving the bearing portion 246 of the cover 243 of the protective member 241. Both the bearing portion 46 and the bearing portion 246 may exist, or only the bearing portion 246 may exist. Both the hole 251A and the first annular groove 251B may exist, or only the first annular groove 251B may exist. The first annular groove 251B is provided on the outer periphery of the hole 251A.

[0123] Arm 250 has a receiving portion for a spring body 261 that houses a torsion spring 260. Here, the second annular groove 257, which is provided on the outer periphery of the first annular groove 251B, serves as the receiving portion for the spring body 261.

[0124] The spring support portion 255 of the arm 250 supports the hook portion 262, which extends in a straight line. The spring support portion 255 is formed as a straight groove extending outward from the second annular groove 257. The spring support portion 255 is provided on a part of the wall of the connecting portion 53. The spring support portion 255 is provided on the first wall portion located on the bottom side of the second annular groove 257, which is one of the pair of wall portions constituting the connecting portion 53. The second wall portion located on the opening side of the second annular groove 257, which is one of the pair of wall portions constituting the connecting portion 53, has a through hole for the hook portion 262 to pass through when the spring body 261 is received into the second annular groove 257 from the opening side of the second annular groove 257.

[0125] The spring support portion 255 of arm 250 differs from the spring support portion 55 of arm 50 in that it does not protrude toward the outer periphery of the retaining portion 52. Therefore, the support member 240 can be more compact in the radial direction than the support member 40.

[0126] Arm 250 does not have guide groove 56. Therefore, the peripheral wall 45 of the main body 242 in the protective member 241 and the peripheral wall 45 of the cover 243 can make their ends contact each other.

[0127] The bearing portion 246 of the cover 243 in the protective member 241 is formed into a cylindrical shape with a diameter larger than that of the bearing portion 46 of the main body 242. The bearing portion 246 is fitted into the first annular groove 251B.

[0128] The spring support portion 248 of the protective member 241 supports the hook portion 263, which extends in a straight line. The spring support portion 248 is provided on the cover 243. The spring support portion 248 is formed by an L-shaped groove on the inner surface of the main plate portion 44 of the cover 243. Alternatively, an annular groove for receiving the end of the spring body 261 along the axial direction may be formed on the inner surface of the main plate portion 44 of the cover 243. This annular groove is provided on the outer peripheral side of the bearing portion 246. The groove of the spring support portion 248 can extend outward from this annular groove.

[0129] The insertion portion 247 in the protective member 241 differs from the insertion portion 47 and is not located on the main board portion 44 of the main body 242. The insertion portion 247 is located on the peripheral wall portion 45 of the main body 242 or the cover 243. The through hole formed in a part of the peripheral wall portion 45 of the main body 242 or the cover 243 is designated as the insertion portion 247.

[0130] The insertion portion 247 includes a protruding tab 247A that protrudes outward from the periphery of the through hole. The protruding tab 247A is bundled together with a binding member BD such as a strapping tape or adhesive tape to the wire harness 30. Thus, the base end of the second end-side extension portion 35E is fixed to the protective member 241.

[0131] The protective member 241 may also include a limiting protrusion 249. The limiting protrusion 249 protrudes inwardly from a portion of the peripheral wall portion 45. The limiting protrusion 249 contacts the retaining portion 52 to inhibit further rotation of the arm 250. Here, the limiting protrusion 249 contacts the arm 250 rotating in the direction in which the force is applied by the force-applying member 260. The limiting protrusion 249 contacts the arm 250 in its intermediate state with the maximum excess length. The limiting protrusion 249 may also contact the arm 250 rotating in the opposite direction to the direction in which the force is applied by the force-applying member 260.

[0132] Figure 10 This is a front view showing the wiring structure 320 of the wire harness in the third variation.

[0133] In this variation, the shape of arm 350 differs from that of arms 50 and 250 described above. The pressing portion 354 of arm 350 is not continuous with the connecting portion 53 along the circumferential direction of the shaft portion 251. The pressing portion 354 and the connecting portion 53 are separated from each other along the circumferential direction of the shaft portion 251. Therefore, the pressing portion 354 can press the wire harness 30 at a position separated from the connecting portion 53, while simultaneously reducing the size of arm 350. The pressing portion 354 has a shape formed by removing the end of the pressing portion 54 along the circumferential direction from the end of the pressing portion 53. In the circumferential direction, the dimensions of the pressing portion 354 are approximately the same as those of the connecting portion 53. The structure of arm 350, except for the pressing portion 354, is the same as that of arm 250 described above.

[0134] Figure 11 This is a front view showing the wiring structure 420 of the wire harness in the fourth variation.

[0135] In this modified example, the shape of arm 450 differs from that of arms 50, 250, and 350 described above. The pressing portion 454 of arm 450 extends from the shaft portion 251 towards the side opposite to the connecting portion 53. Like the pressing portion 354 of arm 350, the pressing portion 454 is not continuous with the connecting portion 53 in the circumferential direction. Like the pressing portion 354, the pressing portion 454 is positioned circumferentially separate from the connecting portion 53. Similar to the pressing portion 354, the dimensions of the pressing portion 454 are approximately the same as those of the connecting portion 53 in the circumferential direction. The structure of arm 450, except for the position of the pressing portion 454, is the same as that of arm 350 described above.

[0136] Figure 12 This is a front view showing the wiring structure 520 of the wire harness in the fifth variation.

[0137] In this modified example, the path of the second section 535 of the wire harness 530 is different from that of the wire harness 30 described above. The second section 535 of the wire harness 530 does not have the aforementioned loop portion 35L and cross portion 35I. After extending from the holding portion 35A, the second extension portion 535C of the second section 535 makes a U-shaped turn and enters the connecting portion 53. After exiting the connecting portion 53, it extends to the insertion portion 247 while circling around the shaft portion 251 and passing through the pressing portion 54.

[0138] exist Figure 12 In the example shown, a torsion spring 260 is used as the force-applying component, but a coil spring 60, etc., could also be used. Additionally, in Figure 12 In the example shown, the following was used Figure 10 The arm shown is 350, but arms 250, 450, etc. can also be used.

[0139] Figure 13 This is an exploded perspective view of the support member 640 in the sixth modified example. Figure 14 This is a rear view showing the support member 640 of the sixth modified example. Figure 15 It is along Figure 14 A cross-sectional view of the XV-XV line.

[0140] In support member 640, the way the protective member 641 supports the arm 650 differs from the previous support methods. Specifically, the arm 650 is supported only by either the body 642 or the cover 643 of the protective member 641. Here, the arm 650 is supported only by the cover 643 of the protective member 641. Furthermore, support member 640 is described using the same torsion spring 260 as support member 240, but it can also be applied to examples using a coil spring 60.

[0141] like Figure 13 As shown, the main body 642 does not have a bearing portion 46 on its main plate portion 644. Instead, the bearing portion 646 on the cover 643 is formed to be longer than the bearing portion 246 on the cover 243 in order to independently support the shaft portion 251. The bearing portion 646 has: a central portion 646A, which fits into a hole 251A in the shaft portion 251; and a cylindrical portion 646B, which fits into a first annular groove 251B in the shaft portion 251. The central portion 646A is longer than the cylindrical portion 646B in the axial direction. Here, the central portion 646A has approximately the same length in the axial direction as the hole 251A.

[0142] like Figure 13 As shown, on the main plate portion 644 of the body 642 of the protective member 641, a through hole 644h is formed instead of the bearing portion 46 at the position where the bearing portion 46 is provided. Figure 14As shown, the diameter of the through hole 644h is larger than the diameter of the central portion 646A and also larger than the diameter of the hole portion 251A. This prevents the end face of the central portion 646A from abutting against the main plate portion 644 of the body 642.

[0143] like Figure 15 As shown, the arm 650 is axially separated from the unsupported side of the body 642 and cover 643 (here, the body 642) by a distance D. The size of this distance D is not particularly limited, and for example, it can be the same as or slightly smaller than the thickness of the main plate portion 644.

[0144] like Figure 14 As shown, the pressing portion 654 of arm 650 extends in the same direction as the pressing portion 354 of arm 350 described above. Figure 13 As shown, the pressing portion 654 and connecting portion 653 of the arm 650 are not cylindrical like the pressing portion 354 and connecting portion 53, but are formed into a groove shape. This facilitates the passage of the ring portion 35L through the pressing portion 654 and connecting portion 653. This groove shape has: a bottom surface extending radially from the shaft portion 251; and a pair of side surfaces extending axially from both ends of the radially extending bottom surface. The bottom surface is located near the side of the main body 642 and cover 643 that does not provide axial support for the arm 650 (here, the main body 642). The bottom surface of this groove shape presses the ring portion 35L along one axial direction. The main plate portion 44 of the side of the main body 642 and cover 643 that provides axial support for the arm 650 (here, the cover 643) presses the ring portion 35L along the other axial direction.

[0145] Figure 16 This is an exploded perspective view showing the support member 740 in the seventh modified example. Furthermore, Figure 16 From along the axial direction and Figure 13 A diagram viewed from the opposite side. Figure 17 This is a rear view showing the support member 740 of the seventh modified example. Figure 18 It is along Figure 17 A cross-sectional view of the XVIII-XVIII line.

[0146] In the support member 740, the way the protective member 741 supports the arm 750 is the same as the way the protective member 641 supports the arm 650. That is, the arm 750 is supported only by either the body 742 or the cover 743 of the protective member 741. Here, the arm 650 is supported only by the cover 643 of the protective member 641.

[0147] The main body 742 differs from the aforementioned main body 642 in that it does not have a through hole 644h formed in the main board portion 744. Therefore, in Figure 17In the rear view shown, the shaft portion 751 of the arm 750 and the bearing portion 746 of the cover 743 are not observed. Neither the through hole 644h nor the bearing portion 46 is provided in the main plate portion 744. The center of both the inner and outer surfaces of the main plate portion 744 are flat surfaces.

[0148] The cover 743 differs from the cover 743 in that the axial length of the central portion 746A of the bearing portion 746 is shorter than the axial length of the central portion 646A described above. The axial length of the central portion 746A is slightly shorter than the length of the hole portion 251A of the arm 750. As a result, the end face of the central portion 746A is prevented from abutting against the main plate portion 744 of the body 742.

[0149] Arm 750 differs from arm 650 in that it has a recess 751C in the shaft portion 751. The surface opposite to the main plate portion 744 (here, body 742) of arm 750 that is not supported by the shaft is designated as the opposing surface. The recess 751C is formed around the opening of the opposing surface in the hole portion 251A. Here, the recess 751C may have an inclined surface that slopes from the opposing surface toward the center of the hole portion 251A, or it may be a groove without an inclination. The recess 751C may also be formed such that the diameter of the opening portion of the opposing surface in the hole portion 251A is larger than that of other portions. The end face of the central portion 746A of the bearing portion 746 may not reach the opposing surface. The end face of the central portion 746A of the bearing portion 746 may also be located at the position of the recess 751C.

[0150] Figure 19 This is a diagram showing the wiring structure 820 of the wire harness in the 8th variation. Figure 20 This is an exploded perspective view showing the support member 840 of the 8th modified example. Figure 21 This is a schematic cross-sectional view showing the wiring structure 820 of the wire harness in the eighth variation. Figure 21 In the middle, only the clamping component 890 is shown in cross-section. Figures 19 to 21 The description of cover 243 is omitted from the various diagrams.

[0151] In the wiring structure 820 of the wire harness, in the open state OS, the holding portion 852 of the arm 850 is located rearward of the center of the rotation axis in the front-to-back direction. Therefore, compared with the case where the holding portion 852 of the arm 850 is located forward of the center of the rotation axis, in the open state OS, when a load F is applied to the travel range 36 of the wire harness 30, the amount of wire harness 30 pulled out can be increased. Figure 19 The center line CL shown is a line that passes through the center of the rotation axis of the arm 850 in the open state OS and is parallel to the vertical direction. In the open state OS, the holding part 852 of the arm 850 is located behind the center line CL.

[0152] For example, the position of the protector 841 in the most relaxed intermediate state of the wiring harness 30 in the intermediate state IS can be closer to the position of the protector 841 in the open state OS than the position of the protector 841 in the closed state CS in the front-rear direction. For example, in the front-rear direction, the position of the body support member 70 can be located at a position further rearward than the center of the position of the protector 841 in the open state OS and the position of the protector 841 in the closed state CS.

[0153] In the support member 840, the shapes of the protective member 841 and arm 850 differ from those of the protective member 41 and arm 50 described above. The protective member 841 and arm 850, like the protective member 241 and arm 250 described above, are formed in a shape where force is applied by the torsion spring 260. Alternatively, the protective member 841 and arm 850 may also be formed in a shape where force is applied by the coil spring 60, similar to the protective member 41 and arm 50 described above.

[0154] The wiring structure 820 of the wire harness includes a clamping member 890. As described above, the clamping member 890 is located between the bellows 33 and the arm 850. The clamping member 890 can be considered as a component of the outer casing, just like the bellows 33, or as a component of the support member 840, just like the arm 850. By providing the clamping member 890, the outer casing can rotate smoothly about an axis along the extension direction, compared to the case where the retaining part 852 holds the bellows 33 in a rotatable manner.

[0155] The clamping member 890 includes a wire harness mounting portion 891 mounted on the wire harness 30 and an arm mounting portion 894 mounted on the arm 850. Here, the arm mounting portion 894 is supported on the arm 850 in a manner that allows it to rotate relative to the arm 850 about an axis extending along the direction of the wire harness 30. The wire harness mounting portion 891 is mounted on the wire harness 30 in a manner that prevents it from rotating relative to the wire harness 30 about an axis extending along the direction of the wire harness 30. Therefore, the clamping member 890, together with the wire harness 30, can rotate relative to the arm 850 about an axis extending along the direction of the wire harness 30. When a torsional force is applied to the wire harness 30 during the opening and closing of the sliding door 12, the clamping member 890 rotates relative to the arm 850 about an axis extending along the direction of the wire harness 30, thereby releasing the torsional force. This suppresses the twisting of the wire harness 30 during the opening and closing of the sliding door 12.

[0156] The wire harness mounting portion 891 clamps the corrugated tube 33. The wire harness mounting portion 891 has a cylindrical portion 892 and a concave-convex portion 893. The concave-convex portion 893 is provided on the inner surface of the cylindrical portion 892. The concave-convex portion 893 corresponds to the concave-convex portion of the corrugated tube 33. The concave-convex portion 893 has a protrusion 893a and a recess 893b. The protrusion 893a and the recess 893b have the same structure as the protrusion 52a and the recess 52b of the holding portion 52 of the arm 50 described above.

[0157] The arm mounting portion 894 has a cylindrical portion 895 and a protrusion 896. The protrusion 896 is provided on the outer surface of the cylindrical portion 895. The retaining portion 852 of the arm 850 has a recess 852b for engaging the protrusion 896. For example, the recess 852b is formed to be slightly larger than the protrusion 896 so that a gap is created between the inner surface of the recess 852b and the outer surface of the protrusion 896. As a result, the arm 850 and the clamping member 890 can rotate about an axis along the extension direction of the wire harness 30. The protrusion dimension of the protrusion 896 is larger than that of the protrusion 893a in the concave-convex portion 893. This makes it easy to ensure the gap between the protrusion 896 and the recess 852b while also making the protrusion 896 more reliably engaged in the extension direction.

[0158] The clamping member 890 is installed with the wiring harness mounting portion 891 positioned relative to the arm mounting portion 894 along the extension direction of the wiring harness 30, closer to the vehicle body 10. In the open state OS, the wiring harness mounting portion 891 of the clamping member 890, like the holding portion 852 of the arm 850, is located rearward in the longitudinal direction relative to the center of the rotation axis. Figure 19 As shown, in the open state OS, the wire harness mounting part 891 of the clamping member 890 is located behind the center line CL.

[0159] The cylindrical portion 895 of the arm mounting portion 894 is thinner than the cylindrical portion 892 of the wire harness mounting portion 891. The retaining portion 852 of the arm 850 covers the cylindrical portion 895, but does not cover the cylindrical portion 892. The bellows 33 is not located inside the retaining portion 852 of the arm 850. Therefore, compared to the case where the bellows 33 is located inside the retaining portion 852 of the arm 850, the retaining portion 852 of the arm 850 can be miniaturized in both the rotational axis direction and the radial direction.

[0160] The clamping member 890 can also be configured such that the protrusion 896 of the arm mounting portion 894 is provided on the outer surface of the cylindrical portion 892 of the wire harness mounting portion 891. The clamping member 890 can also be mounted such that the arm mounting portion 894 is located on the vehicle body 10 side, along the extension direction of the wire harness 30, compared to the wire harness mounting portion 891. In these cases, the bellows 33 can also be configured to be located inside the holding portion 852 of the arm 850.

[0161] like Figure 21 As shown, the clamping member 890 is held in the arm 850 in a direction that intersects the tangent direction of the circle centered on the rotation center. This prevents the rotation radius of the clamping member 890 from exceeding the rotation radius of the arm 850, thereby preventing the support member 840 from becoming radially enlarged. Figure 21In the example shown, the angle between the tangent direction of the circle and the extension direction of the clamping member 890 is 15 degrees. For example, the angle between the tangent direction of the circle and the extension direction of the clamping member 890 can be greater than 0 degrees and less than 20 degrees.

[0162] The retaining portion 852 of the arm 850 is composed of a first portion 852X and a second portion 852Y. The first portion 852X and the second portion 852Y are formed such that the retaining portion 852 is divided into two halves along the axial direction. The first portion 852X is integrally formed with the connecting portion 653. The second portion 852Y is separate from the first portion 852X. The second portion 852Y may also be integrally formed with the first portion 852X via a hinge or the like. The second portion 852Y is mounted to the first portion 852X by fastening or the like.

[0163] The insertion portion 847 in the main body 842 of the protective member 841 is not a hole, but a slot. This facilitates the insertion of the wire harness 30 into the insertion portion 847. The insertion portion 847 is provided by interrupting a portion of the peripheral wall portion 45 of the main body 842. At the position of the insertion portion 847, a slot-shaped insertion portion 847 is provided by omitting a portion of the peripheral wall portion 45, including the end protruding from the main board portion 44. Here, the insertion portion 847 is positioned such that the peripheral wall portion 45 is completely absent. The upper opening of the slot-shaped insertion portion 847 can be blocked by a cover (not shown).

[0164] The inner peripheral wall 854a of the pressing portion 654 of the arm 850 protrudes further outward relative to the rotation center than the inner peripheral wall of the connecting portion 653. Therefore, in the closed state CS, it is possible to prevent the overlap of the loop portion 35L of the wire harness 30 from lengthening in the extending direction. Here, the inner peripheral wall of the connecting portion 653 is the outer peripheral surface of the shaft portion 251. The inner peripheral wall 854a of the pressing portion 654 protrudes further outward than the outer peripheral surface of the shaft portion 251.

[0165] Furthermore, the structures described in the above embodiments and variations can be appropriately combined within a range that does not contradict each other.
