[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described.

[0010] The wiring structure of the wire harness in this disclosure is as follows:

[0011] (1) A wire harness routing structure for connecting a first device provided on the vehicle body and a second device provided on a slide structure, comprising: a wire harness including a section between a portion supported on the vehicle body and a portion supported on the slide structure, wherein the bending state of the wire harness changes due to the sliding movement of the slide structure; and a restricting component for restricting the bending state of the section, wherein the restricting component comprises: a support member attached to the slide structure; a first arm rotatably supported on the support member around a first rotation axis; and the first arm The wire harness routing structure comprises a second arm rotatably supported around a second rotation axis, a first biasing member that biases the first arm in one direction along the rotational direction around the first rotation axis, and a second biasing member that biases the second arm in one direction along the rotational direction around the second rotation axis, wherein both the first and second rotation axes are located on one side with respect to the wire harness, and the first arm or the second arm has a contact surface that contacts the wire harness from the one side to restrict the bending of the wire harness.

[0012] According to the wire harness routing structure of (1), since both the first and second rotation axes are located on one side of the wire harness, it is not necessary to route the wire harness between the first and second rotation axes, and the wire harness can be routed in an easy manner.

[0013] (2) In the wire harness routing structure of (1), the slide structure moves between a first slide position and a second slide position relative to the vehicle body, at the first slide position the first arm and the second arm take a first rotational position, at the second slide position the first arm and the second arm take a second rotational position, at a third slide position between the first slide position and the second slide position the first arm and the second arm take a third rotational position, and the first biasing member and the second biasing member may be biased in the direction from the first rotational position to the third rotational position. This enhances the effect of suppressing wire harness slack at the third slide position, which is intermediate between the first slide position and the second slide position.

[0014] (3) In the wire harness routing structure of (2), the sliding structure is a sliding door of a vehicle, the first and second rotating shafts extend in the vehicle width direction, in the first rotation position the first and second rotating shafts are aligned in the vertical direction, and in the third rotation position the first and second rotating shafts are aligned in the front-rear direction and the wire harness may be placed on the contact surface. This makes it possible to route the wire harness by placing it on the contact surface in the third rotation position, thus facilitating the routing of the wire harness.

[0015] (4) In the wire harness routing structure of (3), the restricting component may have a restricting wall located to the side of the wire harness in the vehicle width direction. This makes it less likely for the wire harness to separate from the contact surface along the vehicle width direction when the first arm and the second arm change their orientation.

[0016] (5) In the wiring harness routing structure of (4), the regulation wall has a first wall portion provided on the support member and a second wall portion provided on the second arm. The first wall portion may extend from a portion of the support member that supports the first rotation axis and regulate a portion of the wiring harness along the first arm. Thereby, it is possible to suppress the wiring harness from separating from the first arm and the second arm.

[0017] (6) In the wiring harness routing structure of any one of (2) to (5), when the dimension from the first rotation axis to the tip of the second arm is taken as the rotation radius, in the posture change between the first rotation posture and the third rotation posture, the rotation radius in the third rotation posture may be maximum. Thereby, in the third rotation posture, the effect of suppressing the slack of the wiring harness is enhanced.

[0018] (7) In the wiring harness routing structure of (6), in an initial stage where the first arm and the second arm change their posture from the third rotation posture toward the first rotation posture, the rotation amount of the second arm may be larger than the rotation amount of the first arm. Thereby, since the second arm rotates larger than the first arm first, it is possible to suppress the posture change in the state where the rotation radius is maximum.

[0019] (8) In the wiring harness routing structure of (6) or (7), the dimension from the second rotation axis to the tip of the second arm may be larger than the dimension from the first rotation axis to the second rotation axis. Thereby, the difference between the torque applied to the first arm and the torque applied to the second arm can be reduced, and the posture change in the state where the rotation radius is maximum can be suppressed.

[0020] (9) In the wiring harness routing structure of any one of (6) to (8), the biasing force of the first biasing member may be larger than the biasing force of the second biasing member. Thereby, the second arm becomes easier to rotate than the first arm, and the posture change in the state where the rotation radius is maximum can be suppressed.

[0021] [Details of the embodiments of this disclosure] Specific examples of the wire harness routing structure of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited to these examples and is intended to include all modifications within the meaning and scope of the claims as indicated by the claims.

[0022] [Embodiment 1] The following describes the wiring harness routing structure according to Embodiment 1. The wiring harness routing structure is a wiring harness routing structure that connects equipment installed on the vehicle body and equipment installed on a sliding structure. In this embodiment, an example in which the sliding structure is a sliding door is described. The sliding structure may be a member other than a sliding door, such as a sliding seat.

[0023] Figure 1 is a schematic plan view showing the wire harness routing structure 20 according to Embodiment 1. The front-rear direction (FRONT, REAR) shown in Figure 1 and other figures corresponds to the front-rear direction of the vehicle. The in-out direction (IN, OUT) shown in Figure 1 and other figures corresponds to the in-out direction relative to the side of the vehicle within the left-right direction of the vehicle. Specifically, Figure 1 shows the left side of the vehicle, with the area to the right of the left side of the vehicle (bottom of the paper) being the interior of the vehicle, and the area to the left of the left side of the vehicle (top of the paper) being the exterior of the vehicle. The up-down direction (UP, LOW) shown in Figure 2, which will be described later, corresponds to the up-down direction of the vehicle.

[0024] First, the relationship between the wire harness routing structure 20 and the vehicle body 10 and sliding door 12 to which the routing structure 20 is applied will be explained. In Figure 1, the wire harness routing structure 20 shown by a solid line indicates the state in which the sliding door 12 is open, and the wire harness routing structure 20 shown by a dashed-dot line indicates the state in which the sliding door 12 is closed. In addition, in Figure 1, some components such as the sliding door 12 are shown by dashed-dot lines in both the open and closed states.

[0025] The vehicle body 10 is provided with an entry / exit opening 11 on its side for occupants to get in and out. The sliding door 12 is slidably supported on the vehicle body 10. The entry / exit opening 11 is opened and closed by the sliding of the sliding door 12. The sliding door 12 includes a door panel 13 that forms the exterior of the sliding door 12 and a door trim 14 provided on the interior side of the door panel 13. For example, a door arm 15 that supports the sliding door 12 is slidably supported on a support rail arranged on the vehicle body 10. A weatherstrip 16 is arranged around the periphery of the entry / exit opening 11 so as to contact the door panel 13 and the vehicle body 10. For example, the weatherstrip 16 is arranged in an annular shape on the outer circumference of the door trim 14 when the sliding door 12 is closed.

[0026] The sliding door 12 is equipped with door-side equipment, such as a power window. This door-side equipment is connected to body-side equipment (such as an ECU) installed on the vehicle body 10 via a wire harness 30. The body-side equipment is an example of a first type of equipment, and the door-side equipment is an example of a second type of equipment. The wire harness 30 is routed to span the vehicle body 10 and the sliding door 12. The wire harness routing structure 20 includes a wire harness 30 connecting the body-side equipment and the door-side equipment, a restricting component 40 attached to the sliding door 12, and a vehicle body support component 90 that supports the wire harness 30 on the vehicle body 10.

[0027] The wire harness 30 includes a wiring member 31 that transmits power or signals between the door-side equipment and the vehicle body-side equipment, and an outer covering member that surrounds the wiring member 31. The wiring member 31 is, for example, an electric wire or an optical fiber cable. The wiring member 31 may be one or multiple. The outer covering member protects the wiring member 31 or bundles multiple wiring members 31 together. Here, the outer covering member includes a corrugated tube 33. The corrugated tube 33 has a shape in which large-diameter cylindrical sections and small-diameter cylindrical sections, each with a circular cross-section, are alternately continuous. The outer and inner surfaces of the corrugated tube 33 have a continuous uneven shape along the extending direction, corresponding to the large-diameter cylindrical sections and small-diameter cylindrical sections. In Figure 1, the ends of the corrugated tube 33 are depicted in a shape that matches the original shape of the corrugated tube 33 with its uneven shape, but the middle section of the corrugated tube 33 is depicted in a simplified shape that omits the uneven shape. The same applies to Figures 2 and onward.

[0028] The wire harness 30 includes a first section 34 supported by the vehicle body 10, a second section 35 supported by the door, and a movable section 36 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 sections along the extending direction of the wire harness 30.

[0029] The first section 34 is supported by the vehicle body 10 by a vehicle body support component 90. The first section 34 is held by the vehicle body 10 when the sliding door 12 is opened and closed. The first section 34 is positioned above the floor panel, for example, and its exposure is suppressed by being covered by a floor carpet or floor mat. For example, the vehicle body 10 is provided with a vehicle body-side harness opening around the entrance / exit opening 11 through which a wire harness 30 is routed. The vehicle body support component 90 shown in Figure 1 supports the portion of the first section 34 that is connected to the movable section 36 around the vehicle body-side harness opening. The movable section 36 extends to the outside of the vehicle body 10 through the vehicle body-side harness opening.

[0030] The second section 35 is a section supported by the sliding door 12 by a restricting component 40. The second section 35 is held by the sliding door 12 and moves with the sliding door 12 relative to the vehicle body 10 when the sliding door 12 is opened and closed. Here, a portion of the second section 35 is supported by the restricting component 40 to move along a certain path relative to the sliding door 12 when the sliding door 12 is opened and closed. The second section 35 is positioned between the door panel 13 and the door trim 14 to minimize exposure. The door trim 14 is provided with a door-side harness opening through which the wire harness 30 is routed. The door-side harness opening is provided, for example, at the bottom of the door trim 14. The free section 36 extends to the outside of the sliding door 12 through the door-side harness opening.

[0031] 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. When the sliding door 12 is opened and closed, the movable section 36 is pulled by the sliding door 12, causing it to move and change its orientation relative to the vehicle body 10 and the sliding door 12. A corrugated tube 33 is provided in the movable section 36. Here, the movable section 36 is assumed to move in three dimensions when the sliding door 12 is opened and closed, and the corrugated tube 33 is capable of following the three-dimensional movement of the movable section 36. One end of the corrugated tube 33 extends to the first section 34 and is supported by the vehicle body 10 by a vehicle body support component 90. The other end of the corrugated tube 33 extends to the second section 35 and is supported by the sliding door 12 by a restricting component 40.

[0032] Here, the movable section 36 has an exposed section. The exposed section is the section that is exposed between the vehicle body 10 and the sliding door 12 when the sliding door 12 is open. Here, the corrugated tube 33 provided in the movable section 36 is exposed. For example, the exposed section is the part of the movable section 36 between the vehicle body side harness opening and the door side harness opening. The exposed section is the part of the passenger entry / exit opening 11 that is exposed in a position that is as unlikely to interfere with passenger entry and exit as possible, such as at the rear and lower part of the vehicle, but which may be stepped on by the passenger.

[0033] In the following, the closed state of the sliding door 12 is referred to as the closed state. The open state of the sliding door 12 is referred to as the open state. The sliding door 12 moves between a first sliding position P1 and a second sliding position P2 relative to the vehicle body 10. The position of the sliding door 12 between the first sliding position P1 and the second sliding position P2 is referred to as the third sliding position P3. The first sliding position P1 is the closed position of the sliding door 12. The second sliding position P2 is the fully open position of the sliding door 12. The third sliding position P3 is the half-open position of the sliding door 12.

[0034] The wire harness 30 includes a section between the portion supported by the vehicle body 10 and the portion supported by the sliding structure 12, in which the bending state changes due to the sliding movement of the sliding structure 12. In this section, the portion of the second section 35 that is housed in the restricting component 40 and the free section 36 are the sections in which the bending state changes due to the sliding movement of the sliding structure 12. The restricting component 40 restricts the bending state of this section.

[0035] The parts of the wire harness routing structure 20 will be described in more detail. Figure 2 is a schematic perspective view showing the wire harness routing structure 20 according to Embodiment 1. Figure 3 is a schematic front view showing the wire harness routing structure 20 according to Embodiment 1. Figure 4 is an exploded perspective view showing the restricting component 40 according to Embodiment 1. Figure 5 is an exploded perspective view showing the first arm 50 and the second arm 60. Figure 6 is an exploded view showing the holding part of the wire harness 30.

[0036] The regulating component 40 comprises a support member 41, a first arm 50, a second arm 60, a first biasing member 70, and a second biasing member 72. The support member 41 is attached to the slide structure 12. The first arm 50 is rotatably supported by the support member 41 around a first rotation axis. The second arm 60 is rotatably supported by the first arm 50 around a second rotation axis. The first biasing member 70 biases the first arm 50 in one direction along the rotational direction around the first rotation axis. The second biasing member 72 biases the second arm 60 in one direction along the rotational direction around the second rotation axis. Here, the first and second rotation axes extend in the vehicle width direction.

[0037] The wire harness 30 includes a first end on the first section 34 side and a second end on the second section 35 side. A first connector 37 is provided at the first end, and a second connector 38 is provided at the second end. Here, the second connector 38 is located outside the support member 41. The second connector 38 is positioned within the sliding door 12, away from the support member 41. The second connector may be held by the support member 41.

[0038] The outer casing of the wire harness 30 includes a fiber tube 32. The fiber tube 32 is a member formed from a fibrous fabric, such as a knitted or woven fabric, into a tubular shape. The fiber tube 32 is more easily bent than the corrugated tube 33. The fiber tube 32 is provided on the second end side of the wire harness 30, extending from the end of the corrugated tube 33. Here, the end of the corrugated tube 33 is located inside the support member 41. Instead of the fiber tube 32, adhesive tape or the like may be provided as the outer casing. Also, the outer casing does not need to be provided on the second end side of the corrugated tube 33.

[0039] In the wire harness 30, the wiring member 31 is inserted into the corrugated tube 33 so as to be able to move freely along the direction of extension. This makes the wiring member 31 less susceptible to the effects of external forces acting on the corrugated tube 33. Specifically, the wiring member 31 only passes through the inside of the corrugated tube 33 and is not fixed to the corrugated tube 33. Therefore, even if the corrugated tube 33 twists, twisting is less likely to occur in the wire harness 30. Furthermore, when the middle section of the corrugated tube 33 is pushed in a direction intersecting the axial direction, it bends as if being pulled in the direction of the push, and the difference between the uneven parts decreases, allowing it to stretch and deform to become longer. At this time, when the wiring member 31 is pushed by the corrugated tube 33, its free movement along the direction of extension suppresses an increase in the tension acting on the wiring member 31.

[0040] The wiring member 31 may be fixed to the fiber tube 32 so as not to move along its extending direction. The wiring member 31 may also be fixed together with the end of the fiber tube 32 by fastening with adhesive tape or cable ties or other fastening materials.

[0041] The support member 41 has a base 42A and a cover 42B. The base 42A and cover 42B may be made of resin, for example. The base 42A and cover 42B may be injection molded products, for example. The base 42A and cover 42B may be configured to maintain their joined state by a locking structure integrally provided with the base 42A and cover 42B. Alternatively, the base 42A and cover 42B may be configured to maintain their joined state by a fastening structure using fastening members such as bolts. Each of the base 42A and cover 42B has a main plate portion 43. At least one of the base 42A and cover 42B has an outer wall portion 44 and a shaft portion 45. The outer wall portion 44 and shaft portion 45 may be present on both the base 42A and cover 42B, or on only one of them.

[0042] The main plate portion 43 is formed in a plate shape. The main plate portion 43 of the base 42A covers the first arm 50 and the second arm 60 from one axial side. The main plate portion 43 of the cover 42B covers the first arm 50 and the second arm 60 from the other axial side.

[0043] The outer wall portion 44 protrudes axially from the outer edge of the main plate portion 43. The outer wall portion 44 is not provided around the entire circumference of the outer edge of the main plate portion 43. The outer wall portion 44 is provided on a part of the outer edge of the main plate portion 43. Another part of the outer edge of the main plate portion 43 is an opening without the outer wall portion 44. Here, the outer wall portion 44 is provided above and behind the main plate portion 43. The inner surface of the outer wall portion 44 above the main plate portion 43 is a curved surface corresponding to the outer surface of the wire harness 30. The support member 41 has two openings 44A and 44B. The wire harness 30 extending from the first end enters the interior of the support member 41 through the lower opening 44A. The wire harness 30 extending from the second end enters the interior of the support member 41 through the upper opening 44B.

[0044] The shaft portion 45 protrudes from the inner surface of the main plate portion 43. The shaft portion 45 engages with the engaging portion 51 of the first arm 50.

[0045] The support member 41 has a spring support portion 46. The spring support portion 46 supports one end of the first biasing member 70. When the biasing member 70 is a torsion coil spring, the spring support portion 46 is usually provided on either the base 42A or the cover 42B.

[0046] The support member 41 has a harness holding portion 47. The harness holding portion 47 holds the wire harness 30. The portion of the wire harness 30 that is held by the harness holding portion 47 is designated as the held portion 35A. In this case, the door-side end of the corrugated tube 33 is designated as the held portion 35A. The held portion 35A is positioned along the front-rear, up-down, and inward-outward directions by being held by the harness holding portion 47. The harness holding portion 47 is provided inside the opening 44B of the main plate portion 43. The positions of the opening 44B and the harness holding portion 47 are not limited to the above-described positions and can be set as appropriate.

[0047] The harness holding portion 47 has a cylindrical portion 48 and a recess 49 provided on the inner surface of the cylindrical portion 48. The recess 49 is formed to be continuous in an annular shape around the axis of the cylindrical portion 48. Here, the harness holding portion 47 holds an intervening member 80 that is externally mounted on the corrugated tube 33. The harness holding portion 47 holds the corrugated tube 33 so that it can rotate around an axis along the extending direction via the intervening member 80. The intervening member 80 holds the corrugated tube 33 so that it cannot rotate around an axis along the extending direction, and the harness holding portion 47 holds the intervening member 80 so that it can rotate around an axis along the extending direction. Alternatively, the harness holding portion 47 may hold the corrugated tube 33 so that it can rotate around an axis along the extending direction without the intervening member 80.

[0048] The intervening member 80 is interposed between the corrugated tube 33 and the support member 41. The intervening member 80 may be considered a component of the outer casing member, similar to the corrugated tube 33, or it may be considered a component of the restricting part 40, similar to the support member 41. With the intervening member 80 provided, the outer casing member rotates more smoothly around an axis along the extending direction compared to the case where the harness holding part 47 rotatably holds the corrugated tube 33.

[0049] The intervening member 80 includes a first mounting portion 81 attached to the wire harness 30 and a second mounting portion 84 attached to the support member 41. Here, the second mounting portion 84 is supported by the support member 41 so as to be rotatable around an axis along the extending direction of the wire harness 30 relative to the support member 41. The first mounting portion 81 is attached to the wire harness 30 so as not to be rotatable around an axis along the extending direction of the wire harness 30 relative to the wire harness 30. Therefore, the intervening member 80, together with the wire harness 30, is rotatable around the support member 41 around an axis along the extending direction of the wire harness 30. When a torsional force is applied to the wire harness 30 when the sliding door 12 is opened or closed, the intervening member 80 can release the torsional force by rotating around the support member 41 around an axis along the extending direction of the wire harness 30. This suppresses twisting of the wire harness 30 when the sliding door 12 is opened or closed.

[0050] The first mounting portion 81 clamps the corrugated tube 33. The first mounting portion 81 has a cylindrical portion 82 and a protruding portion 83. The protruding portion 83 is provided on the inner surface of the cylindrical portion 82. The protruding portion 83 corresponds to the protrusions and recesses of the corrugated tube 33. The protruding portion 83 has a convex portion 83a and a concave portion 83b. The convex portion 83a fits into the concave portion of the corrugated tube 33, and the convex portion of the corrugated tube 33 fits into the concave portion 83b. This restricts the movement of the corrugated tube 33 along the extending direction relative to the intervening member 80.

[0051] The second mounting portion 84 has a protrusion 86. The protrusion 86 is provided on the outer surface of the cylindrical portion 82. The protrusion 86 fits into a recess 49 of the harness holding portion 47 of the support member 41. For example, the recess 49 is formed to be slightly larger than the protrusion 86 so that there is a gap between the inner surface of the recess 49 and the outer surface of the protrusion 86. This allows the support member 41 and the intervening member 80 to rotate around an axis along the extending direction of the wire harness 30. The protrusion 86 has a larger protrusion dimension than the protrusion 83a in the recessed portion 83. This makes it easier to configure the protrusion 86 to catch more reliably in the extending direction while ensuring a gap between the protrusion 86 and the recess 49. The second mounting portion may have another cylindrical portion extending from one end of the cylindrical portion 82, and the protrusion 86 may be provided on this other cylindrical portion. For example, this other cylindrical portion may be formed to be thinner than the cylindrical portion 82, and a fiber material tube 32 may be passed through it.

[0052] The first arm 50 has an engaging portion 51, a shaft portion 52, and a routing surface 53. The first arm 50 may be made of, for example, resin. The first arm 50 may be, for example, an injection molded product. The engaging portion 51 engages with the shaft portion 45. The portion where the engaging portion 51 and the shaft portion 45 engage is the first rotation axis. The shaft portion 52 rotatably supports the second arm 60. The engaging portion 51 is provided at one end of the first arm 50, and the shaft portion 52 is provided at the other end. The routing surface 53 is the outer surface of the first arm 50 between the engaging portion 51 and the shaft portion 52. The wire harness 30 is routed along the routing surface 53.

[0053] The first arm 50 has two spring support portions 54 and 55. The spring support portion 54 supports the other end of the first biasing member 70. The spring support portion 55 supports one end of the second biasing member 72.

[0054] The second arm 60 has an engaging portion 61, a tip portion 62, and a routing surface 63. The second arm 60 may be made of, for example, resin. The second arm 60 may be, for example, an injection-molded product. The engaging portion 61 engages with the shaft portion 52. The portion where the engaging portion 61 and the shaft portion 52 engage is formed as the second rotation axis. The engaging portion 61 is provided at one end of the second arm 60. The tip portion 62 is the other end of the second arm 60. The routing surface 63 is the outer surface of the second arm 60. The wire harness 30 is routed along the routing surface 63.

[0055] Both the first and second rotation axes are located on one side relative to the wire harness 30. Viewed from the axial direction, both shaft portions 45 and 52 are located on the same side relative to the wire harness 30. Specifically, at the third slide position P3, both shaft portions 45 and 52 are located below the wire harness 30 which is placed on the routing surfaces 53 and 63.

[0056] The second arm 60 has a spring support portion 64. The spring support portion 64 supports the other end of the second biasing member 72.

[0057] The support member 41 restricts the axial movement (in this case, inward and outward direction) of the rotation axis between the first arm 50 and the second arm 60. The main plate portion 43 of the base 42A and cover 42B restricts the inward and outward movement of the first arm 50 and the second arm 60.

[0058] The main plate portion 43 has an arc-shaped outer edge portion 43A. The arc-shaped outer edge portion 43A is part of a circle centered on the shaft portion 45. The radius of this circle is the radius of curvature of the arc-shaped outer edge portion 43A. The radius of curvature of the arc-shaped outer edge portion 43A is the same as or greater than the distance between the shaft portion 45 and the shaft portion 52. In any rotational position, the shaft portion 52 is located inside the arc-shaped outer edge portion 43A and is covered by the main plate portion 43.

[0059] The radius of curvature of the arc-shaped outer edge portion 43A is smaller than the sum of the distance between the shaft portion 45 and the shaft portion 52 and the distance from the shaft portion 52 to the tip portion 62. The tip portion 62 is located outside the arc-shaped outer edge portion 43A in any rotational position. Here, the tip portion 62 is located outside the arc-shaped outer edge portion 43A in any rotational position. The radius of curvature of the arc-shaped outer edge portion 43A may be equal to or greater than the sum of the distance between the shaft portion 45 and the shaft portion 52 and the distance from the shaft portion 52 to the tip portion 62. The tip portion 62 is located inside the arc-shaped outer edge portion 43A in any rotational position and may be covered by the main plate portion 43.

[0060] Here, the first biasing member 70 and the second biasing member 72 are each torsion coil springs S. The first biasing member 70 and the second biasing member 72 may each be springs other than torsion coil springs S. The torsion coil spring S includes a spring body SB and hook portions SF1 and SF2 provided at both ends of the spring body SB. The spring body SB is made of wire extending in a coil shape. The hook portions SF1 and SF2 extend from the ends of the spring body SB in a direction different from the circumferential direction of the coil.

[0061] The shaft portion 45 is passed through the spring body SB of the torsion coil spring S which forms the first biasing member 70. Here, the shaft portion 45 of the base 42A is triple-cylindrical, but it may also be double-cylindrical with only the innermost shaft and the outermost annular portion, or only the innermost shaft portion. The engaging portion 51 is double-cylindrical, but it may also be only the cylinder that fits into the innermost shaft portion of the shaft portion 45. The cylinder portion of the engaging portion 51 fits into the cylinder portion of the shaft portion 45. The shaft portion 45 of the cover 42B may be a cylinder portion of any of the cylindrical specifications of the base 42A, or it may fit into the cylinder portion of the engaging portion 51. When the shaft portion 45 is double-cylindrical or more, the spring body SB is housed between the outer cylinder portion of the engaging portion 51 and the outermost cylinder portion of the shaft portion 45, and when the shaft portion 45 is only the innermost shaft portion, the spring body SB may be exposed. The hook portion SF1 of the torsion coil spring S forming the first biasing member 70 is hooked onto and supported by the spring support portion 46 of the support member 41. The hook portion SF2 at the other end of the torsion coil spring S forming the first biasing member 70 is hooked onto and supported by the spring support portion 54 of the first arm 50. The hook portion SF1 hooked onto the support member 41 does not move even when the first arm 50 rotates. The hook portion SF2 hooked onto the first arm 50 moves in the circumferential direction as the first arm 50 rotates. As a result, the spring body SB expands and contracts when the first arm 50 rotates.

[0062] The shaft portion 52 is passed through the spring body SB of the torsion coil spring S which forms the second biasing member 72. Here, the shaft portion 52 is triple-tubular, but it may also be double-tubular, consisting only of the innermost shaft and the outermost annular portion, or it may also be just the innermost shaft portion. The engaging portion 61 is double-tubular, but it may also be just the tube that fits onto the innermost shaft portion of the shaft portion 52. The tube portion of the engaging portion 61 fits onto the tube portion of the shaft portion 52. If the shaft portion 52 is double-tubular or more, the spring body SB is housed between the outer tube portion of the engaging portion 61 and the outermost tube portion of the shaft portion 52, and if the shaft portion 52 consists only of the innermost shaft portion, the spring body SB may be exposed. The hook portion SF1 of the torsion coil spring S which forms the second biasing member 72 is hooked onto and supported by the spring support portion 55 of the first arm 50. The hook portion SF2 at the other end of the torsion coil spring S, which forms the second biasing member 72, is hooked onto and supported by the spring support portion 64 of the second arm 60. When the second arm 60 rotates relative to the first arm 50, the hook portion SF1 hooked onto the first arm 50 and the hook portion SF2 hooked onto the second arm 60 move relative to each other in the circumferential direction. As a result, the spring body SB expands and contracts when the second arm 60 rotates.

[0063] The biasing direction of the first biasing member 70 and the biasing direction of the second biasing member 72 are the same when viewed from the axial direction. This biasing direction lifts the tips of each arm 50, 60 upward and forward of the vehicle. In Figure 3, this is a counterclockwise direction around the first and second rotation axes, respectively.

[0064] The second arm 60 is restricted from rotating by more than a predetermined angle relative to the first arm 50 in the direction biased by the second biasing member 72. As shown in the third slide position P3 in Figure 3, the cable routing surface 53 of the first arm 50 and the cable routing surface 63 of the second arm 60 do not rotate in the direction biased by the second biasing member 72 more than the orientation in which they extend linearly. Such rotation restriction may be achieved, for example, by abutting one end of the cable routing surface 53 with one end of the cable routing surface 63.

[0065] Each of the cable routing surfaces 53 and 63 is formed such that its center in the width direction is slightly lower than both ends in the width direction. Each of the cable routing surfaces 53 and 63 may also be a flat surface in the width direction.

[0066] The cable routing surface 63 has an arc-shaped extension portion 63A and a linear extension portion 63B. The tip portion 62 of the second arm 60 is formed in a circular shape when viewed from the axial direction. The outer surface of the tip portion 62 is the arc-shaped extension portion 63A. The linear extension portion 63B is the outer surface of the portion of the second arm 60 from the center of the circle of the tip portion 62 to the shaft portion 52. The cable routing surface 53 of the first arm 50 is continuous with the linear extension portion 63B and extends linearly in the same way as the linear extension portion 63B.

[0067] As the slide structure 12 slides, the tension pulling the wire harness 30 toward the other side (vehicle body side) along the direction of movement changes. This change in tension occurs because the sliding movement of the slide structure 12 changes the positional relationship between the support member 41 and the vehicle body support part 90, thereby changing the path of the wire harness 30 between them. As the tension changes, the first arm 50 and the second arm 60 rotate. When the tension changes, the difference between the tension and the biasing force provided by the biasing members 70 and 72 changes. When the tension becomes greater than the biasing force, the first arm 50 and the second arm 60 move downward against the biasing force. When the biasing force becomes greater than the tension, the first arm 50 and the second arm 60 move upward due to the biasing force.

[0068] When the sliding door 12 is in the third sliding position P3, slack occurs between the retained portion 35A of the wire harness 30 and the portion supported by the vehicle body support component 90, or the tension is low even if no slack occurs. At this time, the biasing force is greater than the tension. As the door moves from this state toward the first sliding position P1 or the second sliding position P2, the slack between the retained portion 35A of the wire harness 30 and the vehicle body support component 90 disappears, and eventually the tension becomes greater than the biasing force.

[0069] The biasing members 70 and 72 may always bias the arms 50 and 60 in the same direction, regardless of the position of the sliding door 12. For example, the spring body SB may always be in either a compressed or extended state compared to its natural length, regardless of the position of the sliding door 12.

[0070] As shown in Figure 3, at the first slide position P1, the first arm 50 and the second arm 60 assume a first rotational position RP1. At the second slide position P2, the first arm 50 and the second arm 60 assume a second rotational position RP2. Here, the second rotational position RP2 is a different position from the first rotational position RP1. At the third slide position P3, the first arm 50 and the second arm 60 assume a third rotational position RP3. The first biasing member 70 and the second biasing member 72 bias the first arm 50 and the second arm 60 in the direction from the first rotational position RP1 to the third rotational position RP3.

[0071] As the slide structure 12 slides relative to the vehicle body 10, the bending state of the wire harness 30 changes. The bending state of the wire harness 30 changes according to the rotational orientation of the first arm 50 and the second arm 60. At the third slide position P3, the wire harness 30 extends linearly in the front-rear direction from the opening 44B to the tip 62 of the second arm 60. Therefore, at the third slide position P3, the position of the first bend in the portion extending toward the vehicle body beyond the opening 44B is located at the arc-shaped extension portion 63A. As the slide structure moves from the third slide position P3 toward the first slide position P1 or the second slide position P2, the position of the first bend in the portion extending toward the vehicle body beyond the opening 44B approaches the opening 44B.

[0072] In the second sliding position P2, a stepping load may be applied to the portion of the wire harness 30 between the tip 62 and the vehicle body support component 90. When this stepping load is applied, the wire harness 30 attempts to extend linearly between the opening 44B and the position where the stepping load is applied. In the second rotational position RP2, the wire harness 30 is bent between the opening 44B and the tip 62 of the second arm 60, so it can be bent and deformed to extend linearly between the opening 44B and the position where the stepping load is applied. At this time, the first arm 50 and the second arm 60 are in a position that has been rotated by, for example, the first arm 50 from the third rotational position RP3. In other words, the first arm 50 and the second arm 60 are in a position that extends straight forward and downward from the first rotation axis.

[0073] The wire harness 30 abuts against the first arm 50, the second arm 60, or both. The first arm 50 or the second arm 60 has a contact surface that abuts against the wire harness 30. The contact surface abuts against the wire harness 30 from one side (the side with the axis of rotation) and restricts the bending of the wire harness 30. The position of the contact surface may change depending on the rotational orientation of the first arm 50 and the second arm 60.

[0074] In the first rotational position RP1, the first rotation axis and the second rotation axis are aligned vertically. In the first rotational position RP1, the outer surface of the shaft portion 52 and the arc-shaped extension portion 63A, etc., can become contact surfaces. In the first rotational position RP1, the contact surfaces strike the wire harness 30 from above.

[0075] In the second rotational position RP2, the first and second rotational axes are aligned in the front-to-back direction. In the second rotational position RP2, the cable routing surface 53, the outer surface of the shaft portion 52, and the arc-shaped extension portion 63A can become contact surfaces. The wire harness 30 is placed on the contact surface. In the second rotational position RP2, the contact surface strikes the wire harness 30 from below.

[0076] In the third rotational position RP3, the first and second rotational axes are aligned in the front-to-back direction. In the third rotational position RP3, the cable routing surface 53, the linearly extending portion 63B, and the arc-shaped extending portion 63A can become contact surfaces. In the third rotational position RP3, the wire harness 30 is placed on the contact surface. In the third rotational position RP3, the contact surface contacts the wire harness 30 from below.

[0077] In the first rotational position RP1 and the second rotational position RP2, a bend exists in the wire harness 30 between the opening 44B and the tip portion 62, in the portion facing the linearly extending wiring surface 53 and the linearly extending portion 63B. Therefore, the bend in the wire harness 30 may have a portion that is separated from the wiring surface 53 and the linearly extending portion 63B.

[0078] In Figure 3, the reference numeral M1 at the third slide position P3 indicates the location along the extending direction of the wire harness 30 where the tip 62 of the wire harness 30 makes contact with the wire harness 30 in the third rotational position RP3. The reference numeral M1 at the first slide position P1 and the second slide position P2 in Figure 3 is applied to the same location on the wire harness 30 as the reference numeral M1 at the third slide position P3. As can be seen from the changes in the location of reference numeral M1 at each slide position in Figure 3, the position in which the wire harness 30 contacts the tip 62 changes with the sliding movement. The change in the contact position with respect to the tip 62 is due to the occurrence of a bend in the portion of the wire harness 30 that faces the routing surface 53 and the linearly extending portion 63B.

[0079] Specifically, in the third rotational position RP3, the wire harness 30 extends along the shortest path from the opening 44B to the tip 62. In contrast, in the first rotational position RP1 and the second rotational position RP2, a bend occurs in the wire harness 30 between the opening 44B and the tip 62, causing the wire harness 30 to extend a longer distance from the opening 44B to the tip 62 than the shortest path. Therefore, in the third rotational position RP3 and in the first rotational position RP1 or the second rotational position RP2, the portion of the wire harness 30 that abuts the tip 62 may shift in the direction of extension of the wire harness 30. Since the wire harness 30 is not constrained by the routing surfaces 53, 63 and is movable relative to the routing surfaces 53, 63, this shift can occur. The length of this shift may be, for example, about 50 mm to 200 mm. The length of this displacement may be, for example, approximately the same as the dimension between the first rotation axis and the second rotation axis (dimension D2 in Figure 7, described later) (approximately 0.5 to 1.5 times).

[0080] The radius of rotation is defined as the distance from the first axis of rotation to the tip of the second arm 60. This radius of rotation can be considered as the radius of rotation of the arm component including the first arm 50 and the second arm 60. The radius of rotation may change as the second arm 60 rotates relative to the first arm 50. In Figure 3, the radius of rotation R1 is the radius of rotation in the first rotational position RP1. The radius of rotation R2 is the radius of rotation in the second rotational position RP2. The radius of rotation R3 is the radius of rotation in the third rotational position RP3. In the change of position between the first rotational position RP1 and the third rotational position RP3, the radius of rotation R3 is largest in the third rotational position RP3.

[0081] In the initial stage of the first arm 50 and the second arm 60 changing their attitude from the third rotational attitude RP3 to the first rotational attitude RP1, the amount of rotation of the second arm 60 is greater than the amount of rotation of the first arm 50. In other words, the second arm 60 rotates more than the first arm 50. This prevents the first arm 50 and the second arm 60 from rotating at a rotational radius R3. If they rotate at a large rotational radius, it may be necessary to create a large space for the first arm 50 and the second arm 60 to avoid interference with surrounding parts. Conversely, if they rotate at a small rotational radius, the space required for the first arm 50 and the second arm 60 to avoid interference with surrounding parts can be reduced.

[0082] For example, if the biasing force of the first biasing member 70 is greater than that of the second biasing member 72, the second arm 60 can rotate more than the first arm 50. Specifically, the force applied from the wire harness 30 to the tip 62 becomes the main component of the torque that rotates the first arm 50 and the second arm 60. Since the first rotation axis is further from the tip 62 than the second rotation axis, the torque of the first arm 50 is greater than the torque of the second arm 60. Even in this case, by making the biasing force of the first biasing member 70 greater than that of the second biasing member 72, the first arm 50 can be made less likely to rotate than the second arm 60.

[0083] The restricting component 40 has a restricting wall RW located to the side of the wire harness 30 in the vehicle width direction. The restricting wall RW has a first wall portion provided on the support member 41. The first wall portion extends from the part of the support member 41 that supports the first rotation axis and restricts the portion of the wire harness 30 that runs along the first arm 50. Here, the main plate portion 43 of the support member 41 functions as the first wall portion 43. The first wall portion 43 does not follow the rotation of the arms 50 and 60.

[0084] [First variation] The regulated component in the first modified example will now be described. Figure 7 is a schematic front view showing the regulated component 140 in the first modified example. In the following description, components similar to those described above will be denoted by the same reference numerals and their descriptions will be omitted.

[0085] In the regulated part 140, the shape of the second arm 160 is different from the shape of the second arm 60. The second arm 160 is formed to be longer than the second arm 60. By making the second arm 160 longer in this way, the difference between the torque of the first arm 50 and the torque of the second arm 160 can be reduced.

[0086] For example, in the example shown in Figure 7, the dimension D1 from the second rotation axis to the tip 62 of the second arm 160 is larger than the dimension D2 from the first rotation axis to the second rotation axis. The larger the dimension D1, the smaller the torque difference can be. The smaller the dimension D1, the easier it is for the wire harness 30 to conform to the arm 160. In light of these factors, for example, dimension D1 may be about 1.5 to 2.5 times the dimension D2.

[0087] [Second variation] The regulated parts relating to the second modified example will now be explained. Figure 8 is a schematic perspective view showing the regulated part 240 relating to the second modified example.

[0088] The restricting wall RW of the restricting component 240 has a second wall portion 65 provided on the second arm 60 in addition to the first wall portion 43. In the restricting component 240, the second wall portion 65 is provided on both sides of the wire harness 30. As a result, both sides of the wire harness 30 are restricted by the second wall portion 65 even at the position of the second arm 60. The second wall portion 65 follows the rotation of the arm 60.

[0089] The second wall portion 65 is formed in a fan shape when viewed from the axial direction. The second wall portion 65 may have a shape other than a fan shape. The second wall portion 65 is provided at the connecting portion between the arc-shaped extending portion 63A and the linear extending portion 63B. One second wall portion 65 is located on both sides of the arc-shaped extending portion 63A and the linear extending portion 63B. The second wall portion 65 may be provided only on the arc-shaped extending portion 63A, or only on the linear extending portion 63B. The portion of the second wall portion 65 provided on the arc-shaped extending portion 63A and the portion provided on the linear extending portion 63B may be provided at positions far apart from each other.

[0090] Here, the restrictive wall RW is molded separately from the second arm 60 and attached to the second arm 60. The restrictive wall RW may also be provided integrally with the second arm 60. The second arm 60 may be a molded product that includes the restrictive wall RW.

[0091] The above-mentioned restricting component 40 does not have a second wall portion 65. Even in this case, the door panel 13 on the exterior side of the wire harness 30 or the door trim 14 on the interior side can serve as a substitute for the second wall portion 65. In the restricting component 240, one of the two second wall portions 65 may be omitted, and the door panel 13 or door trim 14 may function as a substitute for the second wall portion 65.

[0092] Figure 9 is a schematic perspective view showing a modified example of a control wall RW.

[0093] As shown in Figure 9, the restricting wall RW may have a connecting wall portion 66 that connects the ends of the second wall portions 65. In this case, even at the position of the second wall portion 65, the entire circumference of the wire harness 30 can be surrounded by the routing surface 63 of the second arm 60, the connecting wall portion 66, and the two second wall portions 65. Alternatively, the restricting wall RW may be configured to have one second wall portion 65 and a connecting wall 66. In this case, the restricting wall RW will be L-shaped when viewed from the direction of extension of the wire harness 30.

[0094] <Effects, etc.> With the wire harness routing structure 20 configured as described above, since both the first and second rotational shafts are located on one side relative to the wire harness 30, it is not necessary to route the wire harness 30 between the first and second rotational shafts, and the wire harness 30 can be routed easily.

[0095] Furthermore, since the wire harness routing structure 20 includes a first arm 50 and a second arm 60, the wire harness 30 conforms more easily to the arms 50 and 60 compared to the case where only one arm is provided. In particular, when the bent portion of the wire harness 30 is located in a linearly extending portion of the routing surfaces 53 and 63, such as in the first rotational position RP1 or the second rotational position RP2, the conformity of the wire harness 30 to the arms 50 and 60 is improved compared to the case where only one arm is provided.

[0096] Furthermore, the first biasing member 70 and the second biasing member 72 bias the first arm 50 and the second arm 60 in a direction from the first rotational position RP1 to the third rotational position RP3. As a result, the effect of suppressing slack in the wire harness 30 is enhanced at the third slide position P3, which is intermediate between the first slide position P1 and the second slide position P2.

[0097] Furthermore, in the third rotational position RP3, the first and second rotational axes are aligned in the front-to-back direction, and the wire harness 30 is placed on the contact surface. This allows the wire harness 30 to be routed by placing it on the contact surface in the third rotational position RP3, making the routing of the wire harness 30 easier.

[0098] Furthermore, the restricting parts 40, 140, and 240 have restricting walls RW located to the sides of the wire harness 30 in the vehicle width direction. This makes it less likely for the wire harness 30 to separate from the contact surface along the vehicle width direction when the first arm 50 and the second arm 60 change their orientation.

[0099] Furthermore, the restricting wall RW of the restricting component 240 has a first wall portion 43 provided on the support member 41 and a second wall portion 65 provided on the second arm 60. This prevents the wire harness 30 from separating from the first arm 50 and the second arm 60.

[0100] Furthermore, as shown in Figure 3, the turning radius R3 is maximum in the third rotational position RP3 during the attitude change between the first rotational position RP1 and the third rotational position RP3. This enhances the effect of suppressing slack in the wire harness 30 in the third rotational position RP3.

[0101] Furthermore, in the initial stage when the first arm 50 and the second arm 60 change their attitude from the third rotational attitude RP3 to the first rotational attitude RP1, the amount of rotation of the second arm 60 is greater than the amount of rotation of the first arm 50. As a result, the second arm 60 rotates more than the first arm 50, which suppresses the attitude change at the maximum rotational radius.

[0102] For example, the biasing force of the first biasing member 70 is greater than that of the second biasing member 72. This makes the second arm 60 easier to rotate than the first arm 50, and suppresses changes in posture when the rotation radius is at its maximum.

[0103] Furthermore, for example, in the regulated part 140, the dimension D1 from the second rotation axis to the tip 62 of the second arm 160 is larger than the dimension D2 from the first rotation axis to the second rotation axis. This reduces the difference between the torque applied to the first arm 50 and the torque applied to the second arm 160, thereby suppressing changes in posture when the rotation radius is at its maximum.

[0104] [Note] The restrictive parts 40, 140, and 240 are formed so that the same type of part can be applied to either the left or right sliding door 12. The restrictive parts 40, 140, and 240 are formed in a symmetrical shape except for parts where asymmetry does not cause functional problems. Parts where asymmetry does not cause functional problems include, for example, parts related to the holding of the biasing members 70 and 72.

[0105] Furthermore, the configurations described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other. [Explanation of Symbols]
