DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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

[0010] The wiring structure of the wire harness according to the present disclosure is as follows.

[0011] (1) A wiring structure of a wire harness connecting a device provided on a vehicle body and a device provided on a sliding door, the wiring harness including a vehicle body side section supported on the vehicle body, a door side section supported on the sliding door, and a floating section between the vehicle body side section and the door side section, and a door support part supporting the door side section on the sliding door, the floating section having an exposed section exposed between the vehicle body and the sliding door when the sliding door is open, the door support part including a slider part provided on the door side section and a guide part having a guide groove for guiding the slider part, the guide groove having a first end and a second end, and a guide part extending from the first end in a direction intersecting an extension direction of the opening and closing groove. a stress absorption groove extending along the opening / closing groove, wherein when a state in which the sliding door is closed is defined as a closed state, a state in which the sliding door is open and no stepped-on load is applied to the exposed section is defined as a first open state, and a state in which the sliding door is open and a stepped-on load is applied to the exposed section is defined as a second open state, the slider portion is located at the first end of the opening / closing groove in the first open state, the opening / closing groove is provided such that the slider portion moves along the opening / closing groove from the first end to the second end when changing from the first open state to the closed state, and the stress absorption groove is provided such that the slider portion moves along the stress absorption groove when changing from the first open state to the second open state.

[0012] According to the wiring structure of the wire harness of (1), when a stepped load is applied to the exposed section, the slider portion moves along the stress absorbing groove, so that excessive stress is not applied to the wire harness. This makes it possible to prevent a large tension from being applied to the wire harness even if a stepped load is applied to the exposed section of the wire harness between the sliding door and the vehicle body.

[0013] (2) In the wiring harness arrangement structure of (1), the door support component may have a biasing portion that biases the slider portion toward the opening / closing groove along the extension direction of the stress absorption groove. This allows the slider portion to return to the first end by the biasing force of the biasing portion when the stepped-on load is released. Also, the biasing force of the biasing portion can act as a resistance against the stepped-on load.

[0014] (3) In the wiring structure of (2), a vehicle body support part that supports the vehicle body side section on the vehicle body at a position of the vehicle body side section adjacent to the free section may be provided, and the biasing part may bias the slider part toward the first end along the extension direction of the opening / closing groove, and in the closed state, the first end may be located farther from the vehicle body support part than the second end. This makes it easier for the part of the free section that is connected to the slider part to be hidden inside the sliding door in the closed state, and less likely to be exposed between the sliding door and the vehicle body.

[0015] (4) In the wiring structure of the wire harness of (3), the second end of the opening / closing groove may be located lower in the vertical direction than the first end, and the end of the stress absorption groove opposite to the first end may be located lower in the vertical direction than the first end, and the biasing portion may bias the slider portion upward in the vertical direction. This makes it easier for the biasing portion to bias the slider portion toward the first end when the slider portion moves along the opening / closing groove and when it moves along the stress absorption groove. Also, by biasing the slider portion toward the first end during the opening and closing of the sliding door, sagging of the free moving section can be suppressed.

[0016] (5) In the wiring structure of any one of (1) to (4), only one set of the slider portion and the guide groove may be provided along the extending direction of the door-side section. This makes it possible to prevent the guide part from becoming large in size in the direction along the main surface of the sliding door, compared to a case in which a plurality of guide grooves each having an opening / closing groove and a stress absorbing groove are provided in the guide part.

[0017] (6) In the wiring structure of the wire harness of (5), the slider portion has an inner slider portion and an outer slider portion that protrude from the same position along the extension direction of the door side section to opposite sides along the inside-outside direction of the vehicle, the guide part has an inner guide plate portion provided on the inside of the vehicle from the door side section and an outer guide plate portion provided on the outside of the vehicle from the door side section, and the guide groove may have an inner guide groove formed in the inner guide plate portion and into which the inner slider portion fits, and an outer guide groove formed in the outer guide plate portion and into which the outer slider portion fits. This makes it easier to prevent the slider portion from coming off the guide groove. Also, it makes it easier to make the inner slider portion and the outer slider portion into a simple shape.

[0018] (7) In the wiring harness arrangement structure of (5) or (6), a slider portion other than the slider portion may not be provided along the extending direction of the door-side section, thereby making it possible to prevent the structure of the door support component from becoming complicated.

[0019] (8) In the wiring structure of the wire harness of (5) or (6), the door support part may include a lower slider part provided below the slider part along the extension direction of the door side section, and the lower slider part may be guided along a lower edge of the guide part between the first open state and the closed state. This allows the wire harness to be guided by the slider part and the lower slider part between the first open state and the closed state. Also, since no guide groove corresponding to the lower slider part is provided, the guide part can be prevented from becoming large.

[0020] (9) In the wiring structure of any one of (1) to (8), the door support part may include a protector that covers and protects the door side section, the slider portion may be provided at an upper end of the protector, and a lower end of the protector may be a free end.

[0021] (10) In the wiring structure of any one of (1) to (4), the slider portion may have a first slider portion and a second slider portion provided at positions spaced apart from each other along the extension direction of the door-side section, the guide groove may have a first guide groove for guiding the first slider portion and a second guide groove for guiding the second slider portion, the first guide groove may have a first opening / closing groove as the opening / closing groove and a first stress absorption groove as the stress absorption groove, and the second guide groove may have a second opening / closing groove as the opening / closing groove and a second stress absorption groove as the stress absorption groove. This allows the door-side section to be guided more smoothly as the sliding door is opened and closed, and therefore the free section connected to the door-side section can also change its posture more smoothly.

[0022] (11) In the wiring harness arrangement structure of (10), the first stress absorption groove and the second stress absorption groove may be provided to extend along a straight line, thereby making it possible to smoothly guide the door-side section when a stepped-on load is applied to the exposed section.

[0023] (12) In the wiring harness arrangement structure of (10) or (11), the first opening / closing groove may be shorter than the second opening / closing groove, thereby making it possible to prevent a space required for a guide component in a sliding door from becoming large.

[0024] (13) In the wiring structure of any one of (10) to (12), the door support component may include a slider holding portion that connects the first slider portion and the second slider portion to keep a constant distance between the first slider portion and the second slider portion, thereby allowing the first slider portion and the second slider portion to move along the guide grooves while keeping a constant distance between them.

[0025] (14) In the wiring structure of the wire harness of (13), the slider holding portion may cover and protect the door-side section from a portion where the first slider portion is provided to a portion where the second slider portion is provided, thereby allowing the slider holding portion to be used as a protector for the wire harness.

[0026] (15) In the wiring structure of any one of (1) to (14), the sliding door may include a door body and a protruding portion protruding from a lower portion of the door body toward the vehicle interior, the guide part is attached to the door body at a position higher than the protruding portion, and the door support part may include a protector that covers and protects the door-side section, the protector having a first protective portion that covers a portion of the door-side section where the slider part is provided, and a second protective portion that extends downward from the first protective portion toward the vehicle interior. In this way, the guide part is accommodated above the protruding portion of the sliding door, and the second protective portion prevents the lower portion of the door-side section from contacting the protruding portion.

[0027] (16) In the wiring harness arrangement structure of any one of (1) to (15), the wire harness may include a wiring member and a corrugated tube wrapped around the wiring member, and the wiring member may be inserted through the corrugated tube in a freely movable manner along the extension direction. Since the corrugated tube is wrapped around the wiring member, a stepping load on the free-moving section is transmitted to the wiring member via the corrugated tube. At this time, since the wiring member can move freely in the extension direction relative to the corrugated tube, the wiring member can easily follow the elongation deformation of the corrugated tube. This makes it possible to suppress an increase in tension of the wiring member even if a stepping load is applied to the free-moving section.

[0028] (17) In the wiring harness arrangement structure of (16), the door support component may include a protector that covers and protects a portion of the door side section where the slider portion is provided, and one end of the corrugated tube may be supported by the protector so as to be rotatable about a central axis. When the corrugated tube changes its position as the sliding door is opened or closed, a torque about the central axis may be applied to the corrugated tube. Even in this case, the corrugated tube can absorb the torque applied to the corrugated tube by rotating about the central axis relative to the protector.

[0029] (18) Also, the wiring structure of the present disclosure is a wiring structure of a wire harness that connects a device provided in a vehicle body and a device provided in a sliding door, and includes a wire harness including a vehicle body side section supported on the vehicle body, a door side section supported on the sliding door, and a floating section between the vehicle body side section and the door side section, and a door support part that supports the door side section on the sliding door, and the floating section is in contact with the vehicle body and the sliding door when the sliding door is open. and the door support component includes a slider portion provided in the door-side section and a guide component having a groove formed therein for guiding the slider portion, a state in which the sliding door is closed is defined as a closed state, a state in which the sliding door is open is defined as an open state, the slider portion moves along the groove when changing between the open state and the closed state, and only one set of the slider portion and the groove is provided along the extending direction of the door-side section. According to this aspect, it is possible to suppress an increase in size of the guide component in the direction along the main surface of the sliding door.

[0030] (19) Also, a door support part of the present disclosure is a door support part that supports the door side section of a wire harness, the door side section being supported by a sliding door, and a floating section between the vehicle body side section and the door side section, on the sliding door, the door support part including a slider part provided on the door side section and a guide part having a guide groove for guiding the slider part, the guide groove having an opening / closing groove having a first end and a second end, and a stress absorbing groove extending from the first end in a direction intersecting an extension direction of the opening / closing groove, the floating section being provided with an exposed section that is exposed between the vehicle body and the sliding door when the sliding door is open, and the sliding door is provided with an exposed section that is exposed between the vehicle body and the sliding door when the sliding door is open, When the state in which the door is closed is defined as a closed state, the state in which the sliding door is open and no stepped-on load is applied to the exposed section is defined as a first open state, and the state in which the sliding door is open and a stepped-on load is applied to the exposed section is defined as a second open state, the first end of the opening / closing groove is the position where the slider portion is located in the first open state, the opening / closing groove is provided such that the slider portion moves from the first end toward the second end of the opening / closing groove when changing from the first open state to the closed state, and the stress absorption groove is provided such that the slider portion moves along the stress absorption groove when changing from the first open state to the second open state.

[0031] According to this door support component, when a stepped-on load is applied to the exposed section, the slider portion moves along the stress absorbing groove, so that excessive stress is not likely to be applied to the wire harness. As a result, even if a stepped-on load is applied to the exposed section of the wire harness between the sliding door and the vehicle body, it is possible to suppress a large tension from being applied to the wire harness.

[0032] [Details of the embodiment of the present disclosure] Specific examples of the wiring structure of the wire harness of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0033] [Embodiment 1] The wiring structure of the wire harness according to the first embodiment will be described below. Fig. 1 is a schematic plan view showing a wiring structure 20 of the wire harness according to the first embodiment. The front-rear direction (FRONT, REAR) and the up-down direction (UP, LOW) shown in Fig. 1 correspond to the front-rear direction and the up-down direction in the vehicle. The inside-outside direction (IN, OUT) shown in Fig. 1 corresponds to the inside-outside direction with respect to the side of the vehicle among the left-right directions in the vehicle. Specifically, Fig. 1 shows the right side of the vehicle, and the side to the left of the right side of the vehicle is the inside of the vehicle, and the side to the right of the right side of the vehicle is the outside of the vehicle.

[0034] First, a relationship between the wiring structure 20 of the wire harness and the vehicle body 10 and the sliding door 12 to which the wiring structure 20 is applied will be described. In Fig. 1, the wiring structure 20 of the wire harness shown by a solid line indicates a state in which the sliding door 12 is open, and the wiring structure 20 of the wire harness shown by a two-dot chain line indicates a state in which the sliding door 12 is closed. In Fig. 1, some members such as the sliding door 12 are shown by two-dot chain lines in both the open and closed states.

[0035] A vehicle body 10 is provided with an opening 11 for passengers to get on and off the vehicle at a side thereof. A sliding door 12 is slidably supported by the vehicle body 10. The opening 11 for passengers to get on and off is opened and closed by the sliding door 12 sliding. The sliding door 12 includes a door panel 13 that defines the appearance of the sliding door 12, and a door trim 14 that is provided on the vehicle interior side of the door panel 13. For example, a support arm 15 that supports the sliding door 12 is slidably supported by a support rail that is disposed on the vehicle body 10. A weather strip 16 is disposed around the periphery of the opening 11 for passengers to get on and off so as to come into contact with the door panel 13 and the vehicle body 10. For example, the weather strip 16 is disposed in a ring shape on the outer periphery side of the door trim 14 when the sliding door 12 is closed.

[0036] The sliding door 12 is provided with door-side devices such as a power window. The door-side devices are connected to vehicle-body-side devices (such as an ECU) provided in the vehicle body 10 via a wire harness 30. The wire harness 30 is routed across the vehicle body 10 and the sliding door 12. The wiring structure 20 for the wire harness includes the wire harness 30 that connects the vehicle-body-side devices and the door-side devices, a door support part 40 that supports the wire harness 30 on the sliding door 12, and a vehicle-body support part 70 that supports the wire harness 30 on the vehicle body 10.

[0037] The wire harness 30 includes a wiring member 31 that transmits power or signals between a door-side device and a vehicle-body-side device, and a corrugated tube 32 that is sheathed by 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 more. The corrugated tube 32 protects the wiring member 31 and bundles the multiple wiring members 31 together. The corrugated tube 32 has a shape in which large-diameter cylindrical portions and small-diameter cylindrical portions, each of which has a circular cross section, are alternately connected. The outer and inner surfaces of the corrugated tube 32 have a continuous uneven shape corresponding to the large-diameter cylindrical portions and the small-diameter cylindrical portions along the extension direction. In FIG. 1, the end portion of the corrugated tube 32 is depicted in a shape that conforms to the original shape of the corrugated tube 32 having an uneven shape, but the middle portion of the corrugated tube 32 is depicted in a simplified shape that omits the uneven shape. The same is true in FIG. 2 and the subsequent figures.

[0038] The wire harness 30 includes a vehicle body side section 33 supported by the vehicle body 10, a door side section 34 supported by the door, and a free section 35 between the vehicle body side section 33 and the door side section 34. The vehicle body side section 33, the door side section 34, and the free section 35 are different sections from each other along the extension direction of the wire harness 30.

[0039] The vehicle body side section 33 is supported on the vehicle body 10 by a vehicle body support part 70. The vehicle body side section 33 is held on the vehicle body 10 when the sliding door 12 is opened or closed. The vehicle body side section 33 is disposed, for example, above a floor panel, and is covered by a floor carpet or a floor mat to prevent it from being exposed. For example, the vehicle body 10 is provided with a vehicle body side harness opening for leading out the wire harness 30 around the entry / exit opening 11. The vehicle body support part 70 shown in FIG. 1 supports a portion of the vehicle body side section 33 that is connected to the free section 35 around the vehicle body side harness opening. The free section 35 extends to the outside of the vehicle body 10 through the vehicle body side harness opening.

[0040] The door side section 34 is a section supported by the sliding door 12 by a door support part 40. When the sliding door 12 is opened or closed, the door side section 34 is held by the sliding door 12 and moves together with the sliding door 12 relative to the vehicle body 10. Here, when the sliding door 12 is opened or closed, a part of the door side section 34 is supported by the door support part 40 so as to move along a fixed path relative to the sliding door 12. The door side section 34 is disposed between the door panel 13 and the door trim 14, so that exposure is suppressed. The door trim 14 is provided with a door side harness opening through which the wire harness 30 is led out. The door side harness opening is provided, for example, in a lower part of the door trim 14. The floating section 35 extends to the outside of the sliding door 12 through the door side harness opening.

[0041] The free-floating section 35 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, as compared with the vehicle body side section 33 and the door side section 34. When the sliding door 12 is opened or closed, the free-floating section 35 is pulled by the sliding door 12, and moves and changes its position relative to the vehicle body 10 and the sliding door 12. The corrugated tube 32 is provided in the free-floating section 35. Here, it is assumed that the free-floating section 35 moves three-dimensionally when the sliding door 12 is opened or closed, and the corrugated tube 32 can follow the three-dimensional movement of the free-floating section 35. One end of the corrugated tube 32 extends to the vehicle body side section 33 and is supported by the vehicle body 10 by a vehicle body support part 70. The other end of the corrugated tube 32 extends to the door side section 34 and is supported by the sliding door 12 by a door support part 40.

[0042] The free movement section 35 has an exposed section 36. The exposed section 36 is a 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 32 provided in the free movement section 35 is exposed. For example, the exposed section 36 is a portion of the free movement section 35 between the vehicle body side harness opening and the door side harness opening.

[0043] The exposed section 36 is exposed at a position that is least likely to interfere with passengers getting on and off, such as a position at the rear and lower part of the boarding / alighting opening 11. However, since the exposed section 36 is exposed to the boarding / alighting opening 11, it is difficult to completely prevent the exposed section 36 from being stepped on by passengers getting on and off through the boarding / alighting opening 11. In addition, since the corrugated tube 32 provided in the free section 35 is easily bent and deformed, it is difficult for the corrugated tube 32 alone to support a stepped-on load. Here, the tension applied to the exposed section 36 is prevented from increasing when a stepped-on load is applied to the exposed section 36.

[0044] In the following, a state in which the sliding door 12 is closed is referred to as a closed state. A state in which the sliding door 12 is open and no load is applied to the exposed section 36 is referred to as a first open state. The first open state is a state in which the free section 35 is in a natural state. A state in which the sliding door 12 is open and a load F is applied to the exposed section 36 is referred to as a second open state.

[0045] Each part of the wiring harness wiring structure 20 will be described in more detail. Fig. 2 is a schematic perspective view showing the wiring harness wiring structure 20. Fig. 3 is a schematic front view showing a first open state. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3. Fig. 5 is a schematic front view showing a closed state. Fig. 6 is a schematic front view showing a second open state. Fig. 7 is an explanatory diagram showing the trajectory of the slider portion 54.

[0046] In the wire harness 30, the wiring member 31 is inserted through the corrugated tube 32 in a freely movable manner along the extending direction. This makes the wiring member 31 less susceptible to the effect of an external force applied to the corrugated tube 32. Specifically, the wiring member 31 simply passes through the inside of the corrugated tube 32 and is not fixed to the corrugated tube 32. Therefore, even if the corrugated tube 32 is twisted, the wire harness 30 is less likely to be twisted. In addition, when the middle part of the corrugated tube 32 is pressed in a direction intersecting the axial direction, the corrugated tube 32 bends as if pulled in the pushed direction while reducing the difference in the concave and convex parts, and can be stretched and deformed to become longer. At this time, when the wiring member 31 is pressed by the corrugated tube 32, the wiring member 31 moves freely along the extending direction, and the tension applied to the wiring member 31 is prevented from increasing.

[0047] The door support component 40 includes a shaft side protector 41, a bearing side protector 46, a guide component 56, and a biasing portion 64.

[0048] The shaft side protector 41 includes a tubular main body 42, a tube holding portion 43, and a shaft portion 44. The shaft side protector 41 is made of resin or metal. The rigidity of the shaft side protector 41 is higher than the rigidity of the corrugated tube 32. The tubular main body 42 is formed in a cylindrical shape. The tube holding portion 43 is provided at one end along the axial direction of the tubular main body 42, and the shaft portion 44 is provided at the other end.

[0049] The tube holding portion 43 holds the corrugated tube 32. Here, an end of the corrugated tube 32 covers the tube holding portion 43. The tube holding portion 43 has an annular protrusion that protrudes from the outer periphery of the cylindrical main body 42. The corrugated tube 32 is held by the tube holding portion 43 as the annular protrusion fits inside the large diameter cylindrical portion of the corrugated tube 32.

[0050] The shaft portion 44 is a portion that is supported by the bearing-side protector 46. The shaft portion 44 has a flange 45. The flange 45 protrudes onto the outer periphery of the cylindrical main body 42 at the other end along the axial direction of the cylindrical main body 42. The flange 45 protrudes onto the outer periphery of the cylindrical main body 42 more than the annular protrusion.

[0051] The bearing side protector 46 includes a bearing portion 47, a protective portion 51, and a slider portion 54. The bearing side protector 46 is made of resin or metal. The rigidity of the bearing side protector 46 is higher than the rigidity of the corrugated tube 32.

[0052] The bearing portion 47 supports the shaft portion 44 so that it can rotate. The bearing portion 47 and the shaft portion 44 each have a cylindrical circumferential surface around the central axis CA. Here, the shaft portion 44 has a cylindrical outer circumferential surface, and the bearing portion 47 has a cylindrical inner circumferential surface. Here, the bearing portion 47 has a pair of restricting wall portions 48. The pair of restricting wall portions 48 are located on both sides of the flange 45 along the central axis CA direction. Between the pair of restricting wall portions 48 is an annular recess 49 into which the flange 45 fits. A portion of the shaft side protector 41 including the tube holding portion 43 extends from the bearing portion 47 to the outside of the bearing side protector 46. An insertion hole 50 corresponding to the cylindrical main body 42 is formed in the center of one of the pair of restricting wall portions 48. An insertion hole 50 corresponding to the wiring member 31 is formed in the center of the other of the pair of restricting wall portions 48.

[0053] An end of the corrugated tube 32 is supported by the bearing-side protector 46 via the shaft-side protector 41 so as to be rotatable about the central axis CA. The corrugated tube 32 rotates integrally with the shaft-side protector 41 about the central axis CA relative to the bearing-side protector 46. At this time, the corrugated tube 32 may not rotate at all about the central axis CA relative to the shaft-side protector 41, or may rotate slightly. The shaft-side protector 41 rotates more easily relative to the bearing-side protector 46 than the corrugated tube 32.

[0054] The corrugated tube 32 may lose its circular shape due to torque. As a result, when the corrugated tube 32 is directly rotated around the central axis CA relative to the bearing-side protector 46 by torque, it may not rotate smoothly. Here, the shaft-side protector 41 attached to the corrugated tube 32 rotates around the central axis CA relative to the bearing-side protector 46, so the corrugated tube 32 can rotate more smoothly than when it is directly rotated relative to the bearing-side protector 46.

[0055] Since the bearing-side protector 46 supports the shaft-side protector 41 so as to be rotatable substantially only about the central axis CA, the space required for the movable body support component is prevented from increasing compared to the case where a spherical portion is used. Note that, depending on the tolerance and play between the shaft portion 44 and the bearing portion 47, the shaft-side protector 41 may be able to rotate somewhat relative to the bearing-side protector 46 in a direction other than the central axis CA.

[0056] The protective portion 51 is continuous with the bearing portion 47. The protective portion 51 covers a portion of the wire harness 30 extending from the bearing portion 47. The protective portion 51 has a protective wall portion 52 that covers at least a portion of the wire harness 30 along the circumferential direction. Here, the protective portion 51 is formed in a tubular shape so that the protective wall portion 52 covers the entire circumference of the wire harness 30. The protective portion 51 may be cylindrical or may be rectangular. The protective wall portion 52 extends from the periphery of an insertion hole 50 formed in the center of the other of the pair of regulating wall portions 48.

[0057] The wiring member 31 passes through the shaft side protector 41 and the bearing side protector 46. The wiring member 31 may be inserted through the shaft side protector 41 and the bearing side protector 46 in a manner allowing it to move freely along the extension direction. This makes the wiring member 31 less susceptible to the effects of external forces acting on the shaft side protector 41 and the bearing side protector 46.

[0058] The slider portion 54 is provided in the door-side section 34. The slider portion 54 protrudes from the outer surface of the protective wall portion 52. The slider portion 54 has a columnar portion that protrudes in a columnar shape from the outer surface of the protective wall portion 52. A circumferential groove is formed on the outer surface of the columnar portion. The slider portion 54 and the protective wall portion 52 may be integrally molded using a mold, or the slider portion 54, which is molded separately from the protective wall portion 52, may be attached to the protective wall portion 52 later.

[0059] The slider portion 54 includes a first slider portion 54A and a second slider portion 54B. The first slider portion 54A and the second slider portion 54B are connected by a slider holding portion so as to keep the distance between the first slider portion 54A and the second slider portion 54B constant. Here, the slider holding portion can be regarded as a slider holding portion. The first slider portion 54A and the second slider portion 54B are provided at positions spaced apart from each other along the extension direction of the door side section 34 on the outer surface of the protective wall portion 52. Therefore, the protective wall portion 52 can be regarded as a slider holding portion. The protective wall portion 52 as a slider holding portion covers and protects the door side section 34 from the portion where the first slider portion 54A is provided to the portion where the second slider portion 54B is provided. The protective wall portion 52 extends linearly between the portion where the first slider portion 54A is provided and the portion where the second slider portion 54B is provided. The protective portion 51 may bend and extend from the portion where the first slider portion 54A is provided to the portion where the second slider portion 54B is provided.

[0060] The guide part 56 has a guide groove 58 that guides the slider part 54. The guide part 56 has a plate-shaped guide body 57 that extends along the door panel 13. The guide groove 58 is formed in the guide body 57. The slider part 54 moves along the guide groove 58 in the guide part 56. The inner peripheral edge of the guide groove 58 fits into the circumferential groove of the slider part 54. The guide groove 58 has an opening / closing groove 59 and a stress absorbing groove 62.

[0061] The opening / closing groove 59 has a first end 60 and a second end 61. The slider portion 54 is located at the first end 60 of the opening / closing groove 59 in the first open state. The opening / closing groove 59 is provided such that the slider portion 54 moves in the opening / closing groove 59 from the first end 60 toward the second end 61 when changing from the first open state to the closed state. The first end 60 is located further forward of the vehicle than the second end 61. In the open state, the second end 61 is located farther from the vehicle body support component 70 than the first end 60. In the closed state, the first end 60 is located farther from the vehicle body support component 70 than the second end 61. In the opening / closing groove 59, the second end 61 is located lower in the vertical direction than the first end 60.

[0062] The stress absorption groove 62 extends from the first end 60 in a direction intersecting the extension direction of the opening / closing groove 59. The stress absorption groove 62 is provided so that the slider portion 54 moves along the stress absorption groove 62 when changing from the first open state to the second open state. The stress absorption groove 62 has an end opposite to the first end 60 at a lower position in the vertical direction than the first end 60. The stress absorption groove 62 extends from the first end 60 forward and downward of the vehicle. The stress absorption groove 62 is shorter than the opening / closing groove 59.

[0063] The guide groove 58 has a first guide groove 58A that guides the first slider portion 54A and a second guide groove 58B that guides the second slider portion 54B. The first guide groove 58A has a first opening / closing groove 59A as the opening / closing groove 59 and a first stress absorption groove 62A as the stress absorption groove 62. The second guide groove 58B has a second opening / closing groove 59B as the opening / closing groove 59 and a second stress absorption groove 62B as the stress absorption groove 62. The first guide groove 58A is located above the second guide groove 58B.

[0064] The first opening / closing groove 59A has a first end 60A and a second end 61A. Here, the first opening / closing groove 59A is composed of only a straight portion. The first opening / closing groove 59A extends linearly from the first end 60A to the second end 61B toward the rear and downward of the vehicle. The first opening / closing groove 59A is shorter than the second opening / closing groove 59B.

[0065] The second opening / closing groove 59B has a first end 60B and a second end 61B. The second opening / closing groove 59B includes a curved portion 59B1. The second opening / closing groove 59B is configured by a combination of the curved portion 59B1 and a straight portion 59B2. In the second opening / closing groove 59B, the first end 60B side is the curved portion 59B1, and the second end 61B side is the straight portion 59B2. One end of the curved portion 59B1 is the first end 60B, one end of the straight portion 59B2 is the second end 61B, and the other end of the curved portion 59B1 and the other end of the straight portion 59B2 are continuous.

[0066] The curved portion 59B1 extends in an arc shape centered on the first end 60A. Here, the curved portion 59B1 is shorter than a quarter-circular arc (a quadrant of a circular arc). The curved portion 59B1 may be longer than a quarter-circular arc. The straight portion 59B2 extends from the other end of the curved portion 59B1 in a tangential direction at the other end of the curved portion 59B1. The straight portion 59B2 is longer than both the curved portion 59B1 and the first opening / closing groove 59A. The extending direction of the straight portion 59B2 and the extending direction of the first opening / closing groove 59A intersect with each other. The first opening / closing groove 59A is inclined more to the horizontal direction than the straight portion 59B2. The straight portion 59B2 extends linearly from the first end 60 toward the rear of the vehicle in parallel with the horizontal direction. The connecting portion between the curved portion 59B1 and the straight portion 59B2 is located directly below the first end 60A. The curved portion 59B1 extends from the connecting portion between the curved portion 59B1 and the straight portion 59B2 toward the front of the vehicle beyond the first end portion 60A. The straight portion 59B2 extends from the connecting portion between the curved portion 59B1 and the straight portion 59B2 toward the rear of the vehicle beyond the first end portion 60A. The first end portion 60B is located further forward of the vehicle than the first end portion 60A, and the second end portion 61B is located further rearward of the vehicle than the first end portion 60A.

[0067] The first stress absorption groove 62A and the second stress absorption groove 62B are provided to extend along a straight line. The second stress absorption groove 62B is located on a virtual extension line of the first stress absorption groove 62A extending downwardly of the vehicle. The first stress absorption groove 62A and the second stress absorption groove 62B have the same length.

[0068] Since the first slider portion 54A and the second slider portion 54B are held at a constant distance by the protective wall portion 52, as shown in FIG. 7, the first slider portion 54A and the second slider portion 54B move in conjunction with each other while maintaining a constant distance. The distance is the distance between the first end portion 60A and the first end portion 60B. In the first open state, the first slider portion 54A is located at the first end portion 60A, and the second slider portion 54B is located at the first end portion 60B. The distance between the second end portion 61A and the second end portion 61B is also the same as the distance between the first end portion 60A and the first end portion 60B.

[0069] The position of the bearing side protector 46 is determined by the positions of the first slider portion 54A and the second slider portion 54B, and the position of the bearing side protector 46 determines the positions of the shaft side protector 41 and the end of the corrugated tube 32. The bearing side protector 46 extends in a direction connecting the positions of the first slider portion 54A and the second slider portion 54B. The end of the corrugated tube 32 supported by the bearing side protector 46 via the shaft side protector 41 extends in the extension direction of the bearing side protector 46.

[0070] The biasing portion 64 biases the slider portion 54 toward the opening / closing groove 59 along the extension direction of the stress absorption groove 62. Here, the biasing portion 64 biases the slider portion 54 toward the first end portion 60 along the extension direction of the opening / closing groove 59. The biasing portion 64 biases the slider portion 54 in a direction between the extension direction of the opening / closing groove 59 and the extension direction of the stress absorption groove 62. The biasing portion 64 may be, for example, a spring such as a coil spring, a power spring, or a constant load spring. The slider portion 54 is provided with a biasing portion support portion 65 that supports one end of the biasing portion 64. The other end of the biasing portion 64 is supported by, for example, the guide body 57 or the like.

[0071] Here, the biasing portion 64 is connected to the first slider portion 54A. The biasing portion 64 biases the first slider portion 54A upward in the vertical direction. As a result, the first slider portion 54A is biased toward the first opening / closing groove 59A along the extension direction of the first stress absorption groove 62A, and is also biased toward the first end portion 60 along the extension direction of the first opening / closing groove 59A.

[0072] The vehicle body support part 70 supports the vehicle body side section 33 to the vehicle body 10 at a position of the vehicle body side section 33 adjacent to the free moving section 35. The vehicle body support part 70 has a tube holding part 71. The tube holding part 71 supports the corrugated tube 32 at a fixed position along the extension direction. The tube holding part 71 may support the corrugated tube 32 rotatably about the central axis CA, or may support the corrugated tube 32 non-rotatably. The vehicle body support part 70 is attached to the vehicle body 10 at a fixed position. As a result, the vehicle body 10 side end of the corrugated tube 32 is held at a fixed position on the vehicle body 10. The vehicle body support part 70 is supported non-rotatably on the vehicle body 10. As a result, the direction in which the vehicle body 10 side end of the corrugated tube 32 extends from the vehicle body support part 70 is held in a fixed direction. The vehicle body support component 70 may be rotatably supported on the vehicle body 10 to allow a pivoting movement for changing the direction in which the end of the corrugated tube 32 extends.

[0073] At each of one end and the other end of the corrugated tube 32, several periods of large diameter cylindrical portions and small diameter cylindrical portions are held by the tube holding portions 43, 71. Therefore, at each of one end and the other end of the corrugated tube 32, bending of the corrugated tube 32 is restricted by the tube holding portions 43, 71.

[0074] The vehicle body connector 37 at one end of the wiring member 31 is connected to a vehicle body device, thereby positioning and fixing the wiring member 31 to the vehicle body 10. The tube holding portion 71 of the vehicle body support part 70 positions and fixes the corrugated tube 32 along the extension direction. Since the wiring member 31 is not fixed to the corrugated tube 32, it is not positioned and fixed to the tube holding portion 71. A fixing portion for positioning and fixing the wiring member 31 to the vehicle body 10 may also be provided between the vehicle body connector 37 and the tube holding portion 71.

[0075] The door-side connector 38 at the other end of the wiring member 31 is connected to a door-side device, and thereby positioned and fixed to the sliding door 12. The portion of the wiring member 31 passing through the shaft-side protector 41 and the bearing-side protector 46 is movable relative to the protectors 41, 46 and moves relative to the sliding door 12, and is not positioned and fixed to the sliding door 12. A fixing portion for positioning and fixing the wiring member 31 to the sliding door 12 may also be provided between the door-side connector 38 and the bearing-side protector 46.

[0076] <Slider operation and deformation of the free-floating section> The operation of the slider portion 54 and the deformation of the free movement section 35 will now be described in more detail.

[0077] When the sliding door 12 is opened or closed, the first slider portion 54A moves along the first opening / closing groove 59A, and the second slider portion 54B moves along the second opening / closing groove 59B. When the second slider portion 54B moves along the curved portion 59B1 from the first end portion 60B to the second end portion 61B, the first slider portion 54A remains at the first end portion 60A until the second slider portion 54B reaches the straight portion 59B2. When the second slider portion 54B moves along the straight portion 59B2, the first slider portion 54A moves along the first opening / closing groove 59A. More specifically, in FIG. 7, when the second slider portion 54B moves along the curved portion 59B1 along the direction of the arrow OC2A, the first slider portion 54A rotates while remaining at the first end portion 60A. 7, when the second slider portion 54B moves on the straight portion 59B2 in the direction of the arrow OC2B, the first slider portion 54A moves on the first opening / closing groove 59A in the direction of the arrow OC1. At this time, due to the addition of a rotational motion, the distance that the first slider portion 54A moves on the first opening / closing groove 59A becomes shorter than the distance that the second slider portion 54B moves on the straight portion 59B2.

[0078] In the first open state, most of the sliding door 12 is located rearward of the entrance / exit opening 11, and therefore the shaft side protector 41 is located rearward of the vehicle body support component 70. At this time, the bearing side protector 46 extends in a direction connecting the first end 60A and the first end 60B, and the corrugated tube 32 extends from the shaft side protector 41 toward the front and downward of the vehicle.

[0079] In the closed state, the sliding door 12 closes the entrance / exit opening 11, and therefore the shaft-side protector 41 is located further forward in the vehicle than the vehicle body support component 70. At this time, the bearing-side protector 46 extends in a direction connecting the first slider portion 54A located near the second end 61A and the second slider portion 54B located near the second end 61B, and the corrugated tube 32 extends from the shaft-side protector 41 toward the rear and downward of the vehicle.

[0080] In the closed state, the first slider portion 54A and the second slider portion 54B are located in the linear grooves. As a result, when the first slider portion 54A is biased toward the first end portion 60A in the closed state, the first slider portion 54A and the second slider portion 54B are easily moved toward the first end portion 60A and the first end portion 60B. Here, sagging may occur in the free movement section 35 in the closed state. Even in this case, the first slider portion 54A and the second slider portion 54B move toward the first end portion 60A and the first end portion 60B, so that the free movement section 35 is easily put in a state where a moderate tension is applied, and sagging is unlikely to occur in the free movement section 35. As a result, the portion of the free movement section 35 that extends outside the door trim 14 in the closed state is unlikely to be exposed to the interior space of the vehicle.

[0081] When a stepping load F is applied to the exposed section 36 or the stepping load F is removed, and the state is changed between the first open state and the second open state, the first slider portion 54A moves along the first stress absorption groove 62A, and the second slider portion 54B moves along the second stress absorption groove 62B. The distance that the first slider portion 54A moves along the first stress absorption groove 62A is the same as the distance that the second slider portion 54B moves along the second stress absorption groove 62B. More specifically, in FIG. 7, when the second slider portion 54B moves along the second stress absorption groove 62B along the direction of the arrow SL2, the first slider portion 54A moves along the first stress absorption groove 62A along the direction of the arrow SL1.

[0082] For example, the exposed section 36 is located above a rigid part of the vehicle (such as the support arm 15 or a step portion of the vehicle). For example, the length of the stress absorbing groove 62 may be set so that the exposed section 36, to which the stepped load F is applied, can move up to the rigid part. After the exposed section 36, to which the stepped load F is applied, reaches the rigid part, the rigid part supports the exposed section 36 from below, making it difficult for the stepped load F to act as tension on the wire harness 30. The presence of the rigid part prevents the exposed section 36, to which the stepped load F is applied, from moving below the step.

[0083] The length of the stress absorbing groove 62 may take into consideration the elongation deformation of the corrugated tube 32 that is fitted to the exposed section 36. The length of the stress absorbing groove 62 can be shortened by the amount of the elongation deformation of the corrugated tube 32.

[0084] In the second open state, the first slider portion 54A and the second slider portion 54B are located in the linear grooves. As a result, in the second open state, when the stepping load F is released and the first slider portion 54A is urged toward the first end 60A, the first slider portion 54A and the second slider portion 54B are likely to move toward the first end 60A and the first end 60B. Therefore, when the stepping load F is released, the first slider portion 54A and the second slider portion 54B are likely to return to the first end 60A and the first end 60B by the urging force of the urging portion 64.

[0085] The angle between the extension direction of the first stress absorption groove 62A and the vertical direction is smaller than the angle between the extension direction of the first opening / closing groove 59A and the vertical direction. Therefore, when the first slider portion 54A moves the same distance from the first end portion 60 along the first stress absorption groove 62A and the first opening / closing groove 59A, the biasing force of the biasing portion 64 is larger when the first slider portion 54A moves along the first stress absorption groove 62A.

[0086] The wiring member 31 is not fixed to the corrugated tube 32 and the protectors 41, 46, and is movable relative to the corrugated tube 32 and the protectors 41, 46 in the extension direction. When the state is changed, the corrugated tube 32 and the protectors 41, 46 first change their posture, and the wiring member 31 is pushed by the corrugated tube 32 and the protectors 41, 46 and changes its posture to follow the corrugated tube 32 and the protectors 41, 46. At this time, the portion of the wiring member 31 that is pushed by the corrugated tube 32 and the protectors 41, 46 changes as appropriate. Even in this case, the wiring member 31 moves relative to the corrugated tube 32 and the protectors 41, 46 in the extension direction, thereby preventing the tension in the portion of the wiring member 31 that is pushed by the corrugated tube 32 and the protectors 41, 46 from becoming too large.

[0087] <Effects, etc.> According to the door support part 40 and the wiring structure 20 for the wire harness including the door support part 40 configured as described above, when a stepping load F is applied to the exposed section 36, the slider part 54 moves along the stress absorbing groove 62, so that excessive stress is not likely to be applied to the wire harness 30. As a result, even if a stepping load F is applied to the exposed section 36 of the wire harness 30 between the sliding door 12 and the vehicle body 10, it is possible to suppress a large tension from being applied to the wire harness 30.

[0088] Furthermore, the door support component 40 has a biasing portion 64 that biases the slider portion 54 toward the opening / closing groove 59 along the extension direction of the stress absorption groove 62. This allows the slider portion 54 to return to the first end portion 60 by the biasing force of the biasing portion 64 when the stepped-on load F is released. Furthermore, the biasing force of the biasing portion 64 can act as a resistance force against the stepped-on load F.

[0089] In addition, the biasing portion 64 biases the slider portion 54 toward the first end portion 60 along the extension direction of the opening / closing groove 59, and in the closed state, the first end portion 60 is located farther from the vehicle body support component 70 than the second end portion 61. As a result, the portion of the free movement section 35 connected to the slider portion 54 is easily hidden in the sliding door 12 in the closed state, and is less likely to be exposed between the sliding door 12 and the vehicle body 10. In addition, even if the space in which the free movement section 35 of the wire harness 30 can be arranged between the vehicle body 10 and the sliding door 12 in the closed state is small, the wiring structure 20 of the wire harness can be easily applied. Here, the connecting portion of the free movement section 35 of the wire harness 30 with the vehicle body side section 33 may be arranged inside the weather strip 16. In this case, when the weather strip 16 is arranged so as to double-surround the door trim 14, the space in which the free movement section 35 between the vehicle body 10 and the sliding door 12 in the closed state can be arranged is small.

[0090] In the first opening / closing groove 59A, the second end 61A is located lower than the first end 60A in the vertical direction, and in the first stress absorption groove 62A, the end opposite to the first end 60A is located lower than the first end 60A in the vertical direction, and the biasing portion 64 biases the first slider portion 54A upward in the vertical direction. This makes it easier for the biasing portion 64 to bias the first slider portion 54A toward the first end 60 when the first slider portion 54A moves along the first opening / closing groove 59A and when the first slider portion 54A moves along the first stress absorption groove 62A. In addition, the first slider portion 54A is biased toward the first end 60A during the opening and closing of the sliding door 12, so that the sagging of the free moving section 35 can be suppressed.

[0091] In addition, two sets of slider parts 54 and guide grooves 58 are provided, namely, a set of the first slider part 54A and the first guide groove 58A, and a set of the second slider part 54B and the second guide groove 58B. This allows the door side section 34 to be guided more smoothly as the sliding door 12 is opened and closed, and the position of the free moving section 35 connected to the door side section 34 can also be changed more smoothly.

[0092] In addition, the first stress absorption groove 62A and the second stress absorption groove 62B are provided to extend along a straight line, which allows the door-side section 34 to be smoothly guided when a stepped-on load F is applied to the exposed section 36.

[0093] In addition, the first opening / closing groove 59A is shorter than the second opening / closing groove 59B, which makes it possible to prevent the space required for the guide component 56 in the sliding door 12 from becoming large.

[0094] The door support component 40 also includes a slider holding portion that connects the first slider portion 54A and the second slider portion 54B to maintain a constant distance between the first slider portion 54A and the second slider portion 54B. This allows the first slider portion 54A and the second slider portion 54B to move along the guide groove 58 while maintaining a constant distance between them.

[0095] The slider holding portion covers and protects the portion of the door-side section 34 from the portion where the first slider portion 54A is provided to the portion where the second slider portion 54B is provided, thereby enabling the slider holding portion to be used as a protector.

[0096] In addition, since the corrugated tube 32 is fitted around the free moving section 35, the stepping load F on the free moving section 35 is transmitted to the wire harness 30 via the corrugated tube 32. At this time, the wire harness 30 can move freely in the extension direction relative to the corrugated tube 32 and the protector, so that the wire harness 30 can follow the elongation deformation of the corrugated tube 32. As a result, even if the stepping load F is applied to the free moving section 35, the tension of the wire harness 30 can be prevented from increasing.

[0097] Moreover, one end of the corrugated tube 32 is supported by the bearing-side protector 46 via the shaft-side protector 41 so as to be rotatable about the central axis CA. When the corrugated tube 32 changes its position as the sliding door 12 is opened or closed, a torque about the central axis CA may be applied to the corrugated tube 32. Even in this case, the corrugated tube 32 can absorb the torque applied to the corrugated tube 32 by rotating about the central axis CA relative to the protector.

[0098] [Additional Notes to Embodiment 1] FIG. 8 is a diagram showing a modified example of the shaft side protector 41 and the bearing side protector 46. In FIG.

[0099] The shaft side protector 141 according to the modified example is a part formed by combining a first divided part 141X and a second divided part 141Y, each having a shape in which the portion through which the wire harness 30 passes is divided along the axial direction. Similarly, the bearing side protector 146 according to the modified example is a part formed by combining a first divided part 146X and a second divided part 146Y, each having a shape in which the portion through which the wire harness 30 passes is divided along the axial direction. This makes it easy to later attach the shaft side protector 141 and the bearing side protector 146 to the wire harness 30 and the corrugated tube 32. The first divided parts 141X, 146X and the second divided parts 141Y, 146Y may be divided in half or in other proportions.

[0100] In the divided parts 146X, 146Y of the bearing side protector 146, a portion that becomes the bearing portion 47 has a rib. A recess is formed in the rib. The rib and recess of the two divided parts 146X, 146Y are combined to form the restricting wall portion 48 and the insertion hole 50. Here, the protective portion 51 of the bearing side protector 146 extends from the outer edge of the rib, not from the periphery of the recess. When the shaft side protector 141 rotates, the portion of the wiring member 31 that extends out from the shaft side protector 141 is held by the periphery of the insertion hole 50.

[0101] The first divided parts 141X, 146X and the second divided parts 141Y, 146Y are fixed to each other by screws, etc. The fixed parts between the first divided parts 141X, 146X and the second divided parts 141Y, 146Y have sufficient rigidity to prevent the cylindrical shape of the shaft part 44 and the bearing part 47 from collapsing even when the torque of the corrugated tube 32, etc. is applied thereto.

[0102] In this modification, the tube holding portion 143 of the shaft side protector 141 covers the corrugated tube 32. This allows the tube holding portion 143 to be attached to the outer periphery of the corrugated tube 32. The tube holding portions 143 of the separate parts 141X, 141Y have protrusions that protrude from the inner surface of the portion that will become the cylindrical main body 42. The protrusions of the two separate parts 141X, 141Y combine to form an annular protrusion that fits around the outside of the small diameter cylindrical portion.

[0103] In the bearing-side protector 146, the slider portion 54 may be provided in either the first divided part 146X or the second divided part 146Y without being divided. A divided slider portion 54 may be provided in each of the first divided part 146X and the second divided part 146Y.

[0104] In addition, although the slider portion 54 has been described above as being provided on the bearing-side protector 46, this is not a required configuration. The slider portion may be provided on the wire harness via a member separate from the bearing-side protector 46.

[0105] Further, although the door support component 40 has been described above as including the shaft side protector 41 and the urging portion 64, this is not an essential configuration. The shaft side protector 41 and the urging portion 64 may be omitted.

[0106] Although the above description has been given assuming that two sets of slider portion 54 and guide groove 58 are provided, this is not a required configuration. Only one set of slider portion and guide groove may be provided. An example in which only one set of slider portion and guide groove is provided will be described in the following embodiment 2.

[0107] [Embodiment 2] Fig. 9 is a schematic plan view showing a wiring structure 220 for a wire harness according to embodiment 2. In Fig. 9, the door support part 240 shown by a solid line is in a first open state, and the door support part 240 shown by a two-dot chain line is in a closed state. Fig. 10 is a schematic front view showing the second open state. Fig. 11 is a cross-sectional view taken along line XI-XI in Fig. 10. In the following description, the parts different from embodiment 1 will be mainly described, and the same reference numerals will be used to refer to the same items as in embodiment 1, and detailed description thereof may be omitted.

[0108] In the wiring structure 220 of the wire harness, the configuration of the door support part 240 is different from that of the door support part 40. Specifically, the door support part 240 is provided with only one set of a slider part 254 and a guide groove 258 along the extending direction of the door side section 34. The guide groove 258 here is a groove provided so that both the opening / closing groove 259 and the stress absorption groove 262 are connected to each other. Here, the guide part 256 is provided with only one guide groove 258 corresponding to the first guide groove 58A. The guide part 256 is not provided with any groove for guiding the slider part 254 of the door side section 34 other than the one guide groove 258. The slider part 254 guided by the guide groove 258 is provided at only one location along the extending direction of the door side section 34.

[0109] As shown in FIG. 11, the slider portion 254 has an inner slider portion 254A and an outer slider portion 254B that protrude from the same position along the extension direction of the door side section 34 to opposite sides along the inside-outside direction of the vehicle. The guide component 256 has an inner guide plate portion 257A provided on the vehicle inner side of the door side section 34 and an outer guide plate portion 257B provided on the vehicle outer side of the door side section 34. The guide groove 258 has an inner guide groove 258A formed in the inner guide plate portion 257A and into which the inner slider portion 254A fits, and an outer guide groove 258B formed in the outer guide plate portion 257B and into which the outer slider portion 254B fits. The inner guide groove 258A and the outer guide groove 258B correspond to the inner slider portion 254A and the outer slider portion 254B provided at the same position along the extension direction of the door side section 34. Therefore, in this case, although there are two sets of slider portions 254 and guide grooves 258 in the inside-outside direction of the vehicle, it can be considered that only one set is provided in the extension direction of the door-side section .

[0110] The guide component 256 has a connecting plate portion 257C. The connecting plate portion 257C connects the inner guide plate portion 257A and the outer guide plate portion 257B. The inner guide plate portion 257A and the outer guide plate portion 257B are connected by the connecting plate portion 257C, so that they are held at a constant interval in the inside-outside direction of the vehicle.

[0111] In this example, the door support component 240 also includes a shaft side protector 241 and a bearing side protector 246. The inner slider portion 254A and the outer slider portion 254B are provided on the protector 246. The inner slider portion 254A protrudes from the surface of the protector 246 facing the inside of the vehicle, and the outer slider portion 254B protrudes from the surface facing the outside of the vehicle.

[0112] The inner slider portion 254A and the outer slider portion 254B are not provided with recesses that fit into the periphery of the corresponding guide groove 258 of the guide plate portions 257A and 257B. The side surfaces of the inner slider portion 254A and the outer slider portion 254B are formed into a cylindrical side surface shape or a truncated cone side surface shape. Even in this case, the inner slider portion 254A fits into the inner guide groove 258A, and the outer slider portion 254B fits into the outer guide groove 258B, thereby preventing the inner slider portion 254A and the outer slider portion 254B from coming out of the corresponding guide grooves 258A and 258B.

[0113] In the wiring harness arrangement structure 220, no slider portion 254 other than the slider portion 254 that fits into the guide groove 258 is provided along the extension direction of the door side section 34. In the wiring harness arrangement structure 220, a second slider portion other than the slider portion 254 may be provided. In this case, the guide part 256 may or may not have a groove into which the second slider portion fits. However, when the guide part 256 has a groove into which the second slider portion fits, the groove may be configured not to have both the opening / closing groove 259 and the stress absorption groove 262. The groove may be configured to guide only one of the state change between the closed state and the first open state and the state change between the first open state and the second open state. The groove may be configured to have, for example, only one of the opening / closing groove 259 and the stress absorption groove 262.

[0114] The slider portion 254 is provided at the upper end of the protector 246. The lower end of the protector 246 is a free end. The protector 246 is rotatably supported by a guide part 256, with the slider portion 254 at the upper end serving as a rotation axis. The protector 246 rotates, for example, when the sliding door 12 is opened or closed, as the lower end is pulled by the wire harness 30.

[0115] In this example, the door support component 240 also includes a biasing portion 264. The biasing portion 264 biases the slider portion 254 in the same manner as the biasing portion 64. The biasing portion 264 and the slider portion 254 are connected by a connecting portion (not shown).

[0116] The sliding door 12 includes a door body 13A and a protruding portion 13B that protrudes from a lower portion of the door body 13A toward the vehicle interior. For example, the door body 13A and the protruding portion 13B are different parts of the door panel 13. The guide part 256 is attached to the door body 13A at a position above the protruding portion 13B. The protector 246 has a first protective portion 251A that covers a portion of the door side section 34 where the slider portion 254 is provided, and a second protective portion 251B that extends downward from the first protective portion 251A toward the vehicle interior. The second protective portion 251B covers a section closer to the vehicle body side connector 37 than the first protective portion 251A.

[0117] As shown in FIG. 11, the second protective portion 251B offsets the upper end and the lower end of the protector 246 in the inside-outside direction of the vehicle. For example, the second protective portion 251B may extend outside the guide part 256 in the first open state. Also, for example, the overhanging portion 13B may be located at a lower height than the second protective portion 251B in the first open state. This allows the portion of the wire harness 30 extending from the protector 246 to pass on the vehicle inner side of the overhanging portion 13B in the first open state, and the contact of the portion with the overhanging portion 13B is suppressed. Also, for example, the overhanging portion 13B may be provided at a position at the same height as the second protective portion 251B in the second open state. This allows the protector 246 to pass on the vehicle inner side of the overhanging portion 13B in the second open state, and the contact of the protector 246 with the overhanging portion 13B is suppressed.

[0118] In the example shown in FIG. 9, the supported portion 34A is provided on the door side section 34 closer to the door side connector 38 than the position where the slider portion 254 is provided. The supported portion 34A is supported by a guide part 256. As the slider portion 254 moves along the guide groove 258 and the protector 246 rotates around the slider portion 254 as a rotation axis, a portion of the door side section 34 between the portion where the slider portion 254 is provided and the supported portion 34A is deformed. The supported portion 34A may be supported by the guide part 256 so as to be rotatable around an axis along the inside-outside direction of the vehicle. The door support part 240 may have a rotation support part 66 that holds the supported portion 34A and is rotatably supported by the guide part 256.

[0119] <Effects, etc.> The wire harness routing structure 220 also provides the same effects as the above-mentioned wire harness routing structure 20, except for the effects provided by providing multiple guide grooves 58, each having an opening / closing groove 59 and a stress absorption groove 62, in the guide part 56.

[0120] Furthermore, according to the wire harness routing structure 220, since only one guide groove 258 into which the slider portion 254 fits, which has the opening / closing groove 259 and the stress absorption groove 262, is provided in the guide part 256, the size of the guide part 256 can be prevented from increasing in size in the direction along the main surface of the sliding door 12, compared to the case of embodiment 1 in which a plurality of guide grooves 58 each having the opening / closing groove 59 and the stress absorption groove 62 are provided in the guide part 56.

[0121] In addition, since the slider parts 254A, 254B and the guide grooves 258A, 258B are provided on both sides in the inside-outside direction of the vehicle, it is easy to prevent the slider parts 254A, 254B from coming off the guide grooves 258A, 258B. In addition, it is easy to make the inner slider part 254A and the outer slider part 254B into a simple shape. For example, the inner slider part 254A does not have a recess into which the periphery of the inner guide groove 258A of the inner guide plate part 257A fits. Similarly, the outer slider part 254B does not have a recess into which the periphery of the outer guide groove 258B of the outer guide plate part 257B fits.

[0122] Further, no slider portion other than the slider portion 254 that fits into the guide groove 258 is provided along the extension direction of the door-side section 34. This makes it possible to prevent the structure of the door support component 240 from becoming complicated.

[0123] Moreover, the slider portion 254 is provided at the upper end of the protector 246, and the lower end of the protector 246 is a free end. This makes it possible to prevent the door support part 240 from becoming large in size, as compared with the door support part 40 in which the slider portions 54 are provided at the upper and lower ends of the protector 41.

[0124] In addition, the sliding door 12 includes the overhanging portion 13B, the guide part 256 is located above the overhanging portion 13B, and the protector 246 has a first protective part 251A and a second protective part 251B. As a result, the guide part 256 is accommodated above the overhanging portion 13B of the sliding door 12, while the second protective part 251B prevents the lower part of the door-side section 34 from contacting the overhanging portion 13B.

[0125] [Additional Note on Embodiment 2] Fig. 12 is a schematic plan view showing a modified example of the wiring harness arrangement structure 20. Fig. 13 is a cross-sectional view taken along line XIII-XIII in Fig. 12.

[0126] 12 also has only one set of a guide groove 358 having an opening / closing groove 359 and a stress absorbing groove 362, and a slider portion 354 that fits into the guide groove 358. In the wire harness routing structure 320, a slider portion 355 that does not fit into the guide groove is provided in addition to the slider portion 354.

[0127] Specifically, the door support component 340 in the wiring structure 320 for the wire harness includes a lower slider portion 355 provided below the slider portion 354 along the extension direction of the door-side section 34. The guide component 356 is not provided with a groove into which the lower slider portion 355 fits. The lower slider portion 355 is guided along the lower edge of the guide component 356 between the first open state and the closed state. The lower edge of the guide component 356 is formed into a shape corresponding to the upper peripheral portion of the second guide groove 58B, for example. As a result, the wire harness 30 can be guided between the first open state and the closed state by the pair of the slider portion 354 and the guide groove 358, as well as the pair of the lower slider portion 355 and the lower edge of the guide component 356. Also, since no guide groove corresponding to the lower slider portion 355 is provided, the guide component 356 can be prevented from becoming large. The configuration in which the lower slider portion 355 is guided along the lower edge of the guide part 356 may be applied to the guide part 256 in the wiring structure 220 of the wire harness described above.

[0128] The present disclosure can be regarded as a wiring structure for a wire harness in which the slider portion 254 moves along the groove of the guide part 256 when the sliding door changes state between the open state and the closed state, and only one set of the slider portion 254 and the groove is provided along the extending direction of the door side section. According to this embodiment, it is possible to suppress an increase in size of the guide part 256 in the direction along the main surface of the sliding door.

[0129] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
