[0012] [Description of Embodiments of the Present Disclosure]

[0013] First, embodiments of the present disclosure will be listed and described.

[0014] The wiring structure of the wiring harness of the present disclosure is as follows.

[0015] (1)A wiring structure for a wire harness that connects a device provided on a vehicle body to a device provided on a sliding door. The wiring structure of the wire harness includes: a wire harness having a vehicle body side section, a door side section, and a floating section, where the vehicle body side section is supported by the vehicle body, the door side section is supported by the sliding door, and the floating section is located between the vehicle body side section and the door side section; and a door support member that supports the door side section on the sliding door. The floating section has an exposed section that is exposed between the vehicle body and the sliding door when the sliding door is open. The door support member includes: a slider section provided on the door side section; and a guide member having a guide groove that guides the slider section. The guide groove has: an opening / closing groove having a first end and a second end; and a stress absorption groove that extends from the first end in a direction intersecting the extension direction of the opening / closing groove. When the state of closing the sliding door is set as the closed state, the state of opening the sliding door without applying a stepping load to the exposed section is set as the first open state, and the state of opening the sliding door with a stepping load applied to the exposed section is set as the second open state, the slider section is located at the first end of the opening / closing groove in the first open state. The opening / closing groove is arranged such that when changing from the first open state to the closed state, the slider section moves from the first end towards the second end in the opening / closing groove. The stress absorption groove is arranged such that when changing from the first open state to the second open state, the slider section moves along the stress absorption groove.

[0016] According to the wiring structure of the wire harness in (1), when a stepping load is applied to the exposed section, the slider section moves along the stress absorption groove, making it difficult to apply excessive stress to the wire harness. Thus, even when a stepping load is applied to the exposed section between the sliding door and the vehicle body in the wire harness, it is possible to suppress the application of a large tension to the wire harness.

[0017] (2)In the wiring structure of the wire harness in (1), it is also possible that the door support member has a biasing portion that biases the slider section towards the opening / closing groove along the extension direction of the stress absorption groove. Thus, when the stepping load is removed, the slider section can return to the first end by the action of the biasing portion. In addition, the force of the biasing portion can act as a resistance against the stepping load.

[0018] (3) In the wiring structure of the wire harness in (2), it may also be that the wiring structure of the wire harness includes a vehicle body support member that supports the vehicle body side section on the vehicle body at a position adjacent to the floating section in the vehicle body side section. The biasing portion biases the slider portion toward the first end along the extending direction of the opening / closing groove. In the closed state, the first end is located at a position farther from the vehicle body support member than the second end. Thus, in the closed state, the portion of the floating section connected to the slider portion is easily hidden inside the sliding door and is difficult to be exposed between the sliding door and the vehicle body.

[0019] (4) In the wiring structure of the wire harness in (3), it may also be that in the opening / closing groove, the second end is located at a position lower than the first end along the vertical direction, and in the stress absorption groove, the end on the side opposite to the first end is located at a position lower than the first end along the vertical direction. The biasing portion biases the slider portion upward along the vertical direction. Thus, when the slider portion moves along the opening / closing groove and when it moves along the stress absorption groove, the biasing portion can easily bias the slider portion toward the first end. In addition, during the opening and closing of the sliding door, the slider portion is biased toward the first end, thereby being able to suppress the sagging of the floating section.

[0020] (5) In the wiring structure of the wire harness according to any one of (1) to (4), it may also be that only one set of the slider portion and the guide groove is provided along the extending direction of the door side section. Thus, compared with the case where a plurality of guide grooves having an opening / closing groove and a stress absorption groove are provided in the guide member, the size of the guide member can be suppressed from increasing in the direction along the main surface of the sliding door.

[0021] (6) In the wiring structure of the wire harness in (5), it may also be that the slider portion includes an inner slider portion and an outer slider portion. The inner slider portion and the outer slider portion project from the same position along the extending direction of the door side section toward opposite sides in the vehicle's inside / outside direction. The guide member includes: an inner guide plate portion provided at a position closer to the vehicle's inside than the door side section; and an outer guide plate portion provided at a position closer to the vehicle's outside than the door side section. The guide groove includes: an inner guide groove formed in the inner guide plate portion for the inner slider portion to fit into; and an outer guide groove formed in the outer guide plate portion for the outer slider portion to fit into. Thus, it is easy to prevent the slider portion from coming off the guide groove. In addition, it is easy to make the inner slider portion and the outer slider portion into simple shapes.

[0022] (7) In the wiring structure of the wire harness in (5) or (6), it may also be that no slider portion other than the slider portion is provided along the extending direction of the door side section. Thus, the complexity of the structure of the door support member can be suppressed.

[0023] (8) In the wiring harness arrangement structure of (5) or (6), the door support member may include a lower slider portion, the lower slider portion is provided at a position lower than the slider portion along the extension direction of the door side section, and the lower slider portion is guided along the lower edge of the guide member between the first open state and the closed state. Thus, the wire harness can be guided by the slider portion and the lower slider portion between the first open state and the closed state. In addition, by not providing a guide groove corresponding to the lower slider, the size of the guide member can be suppressed.

[0024] (9) In the wiring harness wiring structure of any one of (1) to (8), the door support component may include a protector that covers and protects the door side section, the slider portion is provided at an upper end of the protector, and the lower end of the protector is a free end.

[0025] (10) In the wiring harness arrangement structure of any one of (1) to (4), the slider portion may include a first slider portion and a second slider portion, the first slider portion and the second slider portion are provided at positions separated from each other along the extension direction of the door side section, the guide groove may include: 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 including a first opening and closing groove as the opening and closing groove and a first stress absorbing groove as the stress absorbing groove, and the second guide groove including a second opening and closing groove as the opening and closing groove and a second stress absorbing groove as the stress absorbing groove. Thus, the door side section can be guided more smoothly as the sliding door is opened and closed, and the floating section connected to the door side section can also change its posture more smoothly.

[0026] (11) In the wiring harness structure of (10), the first stress absorbing groove and the second stress absorbing groove may be provided so as to extend along a straight line. Thus, when a stepping load is applied to the exposed section, the door side section can be smoothly guided.

[0027] (12) In the wiring harness arrangement structure of (10) or (11), the first opening and closing groove may be shorter than the second opening and closing groove. This can prevent an increase in the space required for the guide member in the slide door.

[0028] In the wiring structure of the wire harness according to any one of (10) to (12), it is also possible that the door support member includes a slider holding portion that connects the first slider portion and the second slider portion and maintains a constant interval between the first slider portion and the second slider portion. Thus, the first slider portion and the second slider portion can maintain a constant interval and move along the guide groove respectively.

[0029] In the wiring structure of the wire harness according to (13), it is also possible that the slider holding portion covers and protects the portion from the portion where the first slider portion is provided to the portion where the second slider portion is provided in the door side section. Thus, the slider holding portion can be used as a protector for the wire harness.

[0030] In the wiring structure of the wire harness according to any one of (1) to (14), it is also possible that the sliding door includes a door main body and a protruding portion that protrudes inward from the lower portion of the door main body. The guiding member is located above the protruding portion and is mounted on the door main body. The door support member includes a protector that covers and protects the door side section. The protector has: a first protection portion that covers the portion where the slider portion is provided in the door side section; and a second protection portion that extends downward and inward from the first protection portion. Thus, the guiding member is accommodated above the protruding portion in the sliding door, and contact between the lower portion of the door side section and the protruding portion is suppressed by the second protection portion.

[0031] In the wiring structure of the wire harness according to any one of (1) to (15), it is also possible that the wire harness includes a wiring member and a corrugated tube. The corrugated tube is externally mounted on the wiring member, and the wiring member is inserted through the corrugated tube in a manner that can float along the extending direction. By externally mounting the corrugated tube on the wiring member, the stepping load on the floating section is transmitted to the wiring member via the corrugated tube. At this time, the wiring member can float in the extending direction relative to the corrugated tube, so that the wiring member can easily follow the elongation deformation of the corrugated tube. Thus, even if a stepping load is applied to the floating section, an increase in the tension of the wiring member can be suppressed.

[0032] In the wiring structure of the wire harness according to (16), it is also possible that the door support member includes a protector that covers and protects the portion where the slider portion is provided in the door side section, and one end portion of the corrugated tube is supported by the protector in a manner that can rotate around the central axis. When the corrugated tube changes its posture as the sliding door opens and closes, a torque around the central axis may be applied to the corrugated tube. In this case, by rotating the corrugated tube around the central axis relative to the protector, the torque applied to the corrugated tube can also be absorbed.

[0033] (18) In addition, the wiring structure of the wiring harness of the present disclosure connects a device installed on a vehicle body with a device installed on a sliding door, wherein the wiring structure of the wiring harness comprises: a wiring harness including a vehicle body side section, a door side section and a floating section, wherein the vehicle body side section is supported by the vehicle body, the door side section is supported by the sliding door, and the floating section is located between the vehicle body side section and the door side section; and a door support component, which supports the door side section on the sliding door, wherein the floating section has an exposed section, and the exposed section is exposed between the vehicle body and the sliding door when the sliding door is open, and the door support component comprises: a slider portion, which is provided in the door side section; and a guide component, which forms a groove, wherein the groove guides the slider portion, sets the closed state of the sliding door to the closed state, and sets the opened state of the sliding door to the open state, wherein the slider portion moves along the groove when the state is changed 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 the size of the guide member in the direction along the main surface of the slide door.

[0034] (19) In addition, the vehicle door support component of the present disclosure supports the door side section of the wiring harness on the sliding door, the wiring harness includes a body side section, the door side section and a floating section, the body side section is supported on the body, the door side section is supported on the sliding door, and the floating section is located between the body side section and the door side section, wherein the vehicle door support component includes: a slider portion, which is arranged in the door side section; and a guide component, which forms a guide groove, and the guide groove guides the slider portion, and the guide groove has: an opening and closing groove, which has a first end and a second end; and a stress absorbing groove, which extends from the first end in a direction intersecting with the extension direction of the opening and closing groove, and an exposed section is provided in the floating section, and the exposed section is in a state where the sliding door is opened. The vehicle body is exposed between the sliding door, and when the closed state of the sliding door is set to the closed state, the open state of the sliding door and the state where no pedal load is applied to the exposed section is set to the first open state, and the open state of the sliding door and the state where a pedal load is applied to the exposed section is set to the second open state, the first end of the opening and closing groove is at the position where the slider portion is located in the first open state, and the opening and closing groove is set as follows: when changing from the first open state to the closed state, the slider portion moves from the first end portion toward the second end portion in the opening and closing groove, and the stress absorbing groove is set as follows: when changing from the first open state to the second open state, the slider portion moves along the stress absorbing groove.

[0035] According to the door support component, when a stepping load is applied to the exposed section, the slider moves along the stress absorbing groove, making it difficult to apply excessive stress to the wire harness. Thus, even if a stepping load is applied to the exposed section between the sliding door and the vehicle body in the wire harness, it is possible to suppress the application of large tension to the wire harness.

[0036] [Details of the embodiments of the present disclosure]

[0037] Specific examples of the wiring structure of the wire harness of the present disclosure are described below with reference to the drawings. In addition, the present disclosure is not limited to these examples, but is shown by the claims, and is intended to include all changes within the meaning and scope equivalent to the claims.

[0038] [Implementation Method 1]

[0039] Hereinafter, the wiring structure of the wire harness according to the first embodiment will be described. Figure 1 This is a schematic plan view showing the wiring structure 20 of the wire harness according to the first embodiment. Figure 1 The front-rear direction (front, rear) and the up-down direction (up, down) shown correspond to the front-rear direction and the up-down direction of the vehicle. Figure 1 The inside-outside direction (inside, outside) shown in FIG. 1 corresponds to the inside-outside direction relative to the side of the vehicle in the left-right direction of the vehicle. Figure 1 , the right side of the vehicle is shown, the left side of the right side of the vehicle is the vehicle interior, and the right side of the right side of the vehicle is the vehicle exterior.

[0040] First, the 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. Figure 1 In FIG. 1 , the wiring harness wiring structure 20 shown by the solid line indicates the state in which the sliding door 12 is opened, and the wiring harness wiring structure 20 shown by the double-dashed line indicates the state in which the sliding door 12 is closed. Figure 1 In the figure, for some components such as the sliding door 12, the open state and the closed state are indicated by two-dot chain lines.

[0041] In a vehicle body 10, an opening 11 for passengers to get on and off is provided on the side. A sliding door 12 is supported by the vehicle body 10 in a slidable manner. By sliding the sliding door 12, the opening 11 for getting on and off is opened and closed. The sliding door 12 includes a door panel 13 that forms the appearance of the sliding door 12 and a door interior 14 provided on the vehicle interior side of the door panel 13. For example, a support arm 15 that supports the sliding door 12 is supported by a support rail disposed on the vehicle body 10 in a slidable manner. A sealing strip 16 is disposed on the periphery of the opening 11 for getting on and off in contact with the door panel 13 and the vehicle body 10. For example, the sealing strip 16 is disposed in a ring shape on the outer peripheral side of the door interior 14 when the sliding door 12 is closed.

[0042] On the sliding door 12, there are provided door-side devices such as an electric window. The door-side device is connected to a vehicle-body-side device (such as an ECU) provided on the vehicle body 10 via a wiring harness 30. The wiring harness 30 is wired so as to extend over the vehicle body 10 and the sliding door 12. The wiring structure 20 of the wiring harness includes: a wiring harness 30 that connects the vehicle-body-side device and the door-side device; a door support member 40 that supports the wiring harness 30 on the sliding door 12; and a vehicle-body support member 70 that supports the wiring harness 30 on the vehicle body 10.

[0043] The wiring harness 30 includes: a wiring member 31 that transmits power or signals between the door-side device and the vehicle-body-side device; and a corrugated tube 32 that is externally mounted on 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 a plurality. The corrugated tube 32 protects the wiring member 31 or bundles a plurality of wiring members 31. The corrugated tube 32 has a shape in which large-diameter cylindrical portions and small-diameter cylindrical portions having circular cross-sections are alternately continuous. On the outer surface and the inner surface of the corrugated tube 32, uneven shapes corresponding to the large-diameter cylindrical portions and the small-diameter cylindrical portions are continuous along the extending direction. In addition, Figure 1 in, the end portions of the corrugated tube 32 are described as having shapes conforming to the original shape of the corrugated tube 32 having uneven shapes, but the middle portion of the corrugated tube 32 is simply described as having a shape in which the uneven shapes are omitted. In Figure 2 the same applies to the subsequent figures.

[0044] The wiring harness 30 includes: a vehicle-body-side section 33 that is supported by the vehicle body 10; a door-side section 34 that is supported by the door; and a floating section 35 that is located 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 floating section 35 are sections that are different from each other along the extending direction of the wiring harness 30.

[0045] The vehicle body side section 33 is supported by a vehicle body support member 70 on the vehicle body 10. The vehicle body side section 33 is held on the vehicle body 10 when the sliding door 12 is opened and closed. The vehicle body side section 33 is arranged, for example, at a position above the floor and is covered with a floor carpet or a floor mat to suppress exposure. For example, a vehicle body side wire harness opening is provided in the vehicle body 10 to lead the wire harness 30 to the periphery of the boarding / alighting opening 11. Figure 1 The illustrated vehicle body support member 70 supports, around the vehicle body side wire harness opening, the portion of the vehicle body side section 33 that is connected to the floating section 35. The floating section 35 extends to the outside of the vehicle body 10 through the vehicle body side wire harness opening.

[0046] The door side section 34 is a section supported by a door support member 40 on the sliding door 12. The door side section 34 is held on the sliding door 12 when the sliding door 12 is opened and closed and moves relative to the vehicle body 10 together with the sliding door 12. Here, a part of the door side section 34 is supported by the door support member 40 to move along a constant path relative to the sliding door 12 when the sliding door 12 is opened and closed. The door side section 34 is arranged between the door panel 13 and the door interior trim 14 to suppress exposure. A door side wire harness opening for leading the wire harness 30 is provided in the door interior trim 14. The door side wire harness opening is provided, for example, at the lower part of the door interior trim 14. The floating section 35 extends to the outside of the sliding door 12 through the door side wire harness opening.

[0047] The floating section 35 is not supported by the vehicle body 10 or the sliding door 12 and can move freely relative to the vehicle body 10 and the sliding door 12 compared to the vehicle body side section 33 and the door side section 34. The floating section 35 is pulled by the sliding door 12 when the sliding door 12 is opened and closed, and thus moves and changes its posture relative to the vehicle body 10 and the sliding door 12. A bellows 32 is provided in the floating section 35. Here, it is assumed that the floating section 35 makes three-dimensional movements when the sliding door 12 is opened and closed, and the bellows 32 can follow the three-dimensional movements of the floating section 35. One end of the bellows 32 extends to the vehicle body side section 33 and is supported by the vehicle body 10 through the vehicle body support member 70. The other end of the bellows 32 extends to the door side section 34 and is supported by the sliding door 12 through the door support member 40.

[0048] The floating 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 opened. Here, the bellows 32 provided in the floating section 35 is exposed. For example, the exposed section 36 is the portion of the floating section 35 between the vehicle body side wire harness opening and the door side wire harness opening.

[0049] The exposed section 36 is exposed at a position as far as possible where interference with the passengers getting on and off the vehicle is difficult, such as at the rear and below the vehicle in the opening 11 for getting on and off. However, since the exposed section 36 is exposed in the opening 11 for getting on and off, it is difficult to completely eliminate the situation where the passengers getting on and off step on it through the opening 11 for getting on and off. In addition, the bellows 32 provided in the floating section 35 is easily bent and deformed, so it is difficult to support the stepping load only by the bellows 32. Here, the tension applied to the exposed section 36 when a stepping load is applied to the exposed section 36 is suppressed from increasing.

[0050] Hereinafter, the state where the sliding door 12 is closed is set as the closed state. The state where the sliding door 12 is open and no stepping load is applied to the exposed section 36 is set as the first open state. The first open state is a state where the floating section 35 is in a natural state. The state where the sliding door 12 is open and a stepping load F is applied to the exposed section 36 is set as the second open state.

[0051] Each part of the wiring structure 20 of the wire harness will be described in more detail. Figure 2 is a schematic perspective view showing the wiring structure 20 of the wire harness. Figure 3 is a schematic front view showing the first open state. Figure 4 is along Figure 3 the cross-sectional view taken along line IV-IV. Figure 5 is a schematic front view showing the closed state. Figure 6 is a schematic front view showing the second open state. Figure 7 is an explanatory view showing the locus of the slider portion 54.

[0052] In the wire harness 30, the wiring member 31 is inserted through the bellows 32 in a manner that can float along the extending direction. Thereby, the wiring member 31 is hardly affected by the external force applied to the bellows 32. Specifically, the wiring member 31 only passes through the inside of the bellows 32 and is not fixed to the bellows 32. Therefore, even if the bellows 32 twists, it is difficult for the wire harness 30 to twist. In addition, the bellows 32 is bent in such a way that when it is pressed in a direction crossing the axial direction at the middle portion, it is pulled in the pressed direction, and the difference between the concave and convex portions becomes smaller, so that it can be elongated and deformed in a lengthened manner. At this time, when the wiring member 31 is pressed by the bellows 32, it floats along the extending direction, thereby suppressing the increase in the tension applied to the wiring member 31.

[0053] The door support member 40 includes a shaft side protector 41, a bearing side protector 46, a guide member 56, and a biasing portion 64.

[0054] The shaft-side protector 41 includes a cylindrical 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 that of the bellows 32. The cylindrical main body 42 is formed in a cylindrical shape. A tube holding portion 43 is provided at one end of the cylindrical main body 42 in the axial direction, and a shaft portion 44 is provided at the other end.

[0055] The tube holding portion 43 holds the bellows 32. Here, the end portion of the bellows 32 covers the tube holding portion 43. The tube holding portion 43 has an annular convex portion that projects outward from the outer circumference of the cylindrical main body 42. By fitting the annular convex portion into the inner side of the large-diameter cylindrical portion of the bellows 32, the bellows 32 is held by the tube holding portion 43.

[0056] The shaft portion 44 is the part supported by the bearing-side protector 46. The shaft portion 44 has a flange 45. The flange 45 projects outward from the outer circumference of the cylindrical main body 42 at the other end in the axial direction of the cylindrical main body 42. The flange 45 projects more outward from the outer circumference of the cylindrical main body 42 than the annular convex portion.

[0057] The bearing-side protector 46 includes a bearing portion 47, a protection 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 that of the bellows 32.

[0058] The bearing portion 47 supports the shaft portion 44 so as to be rotatable. The bearing portion 47 and the shaft portion 44 each have a cylindrical peripheral surface around the central axis CA. Here, the shaft portion 44 has a cylindrical outer peripheral surface, and the bearing portion 47 has a cylindrical inner peripheral 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 in the direction of the central axis CA with respect to the flange 45. An annular recess 49 for fitting the flange 45 is formed between the pair of restricting wall portions 48. The part 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 at the center of one of the pair of restricting wall portions 48. An insertion hole 50 corresponding to the wiring member 31 is formed at the center of the other of the pair of restricting wall portions 48.

[0059] The end portion of the bellows 32 is supported by the bearing-side protector 46 via the shaft-side protector 41 so as to be rotatable around the central axis CA. The bellows 32 and the shaft-side protector 41 rotate integrally around the central axis CA with respect to the bearing-side protector 46. At this time, the bellows 32 may not rotate at all around the central axis CA with respect to the shaft-side protector 41, or may rotate slightly. The shaft-side protector 41 is more easily rotatable with respect to the bearing-side protector 46 than the bellows 32.

[0060] The circular shape of the bellows 32 may be deformed due to torque. Thus, when the bellows 32 is directly rotated about 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 bellows 32 rotates about the central axis CA relative to the bearing-side protector 46, and thus can rotate more smoothly than when the bellows 32 is directly rotated relative to the bearing-side protector 46.

[0061] The bearing-side protector 46 supports the shaft-side protector 41 so that it can rotate substantially only about the central axis CA. Therefore, compared with the case of using a spherical portion, an increase in the space required for the movable body support member can be suppressed. Further, due to the tolerance, clearance, etc. between the shaft portion 44 and the bearing portion 47, the shaft-side protector 41 may be able to rotate slightly relative to the bearing-side protector 46 in addition to rotating about the central axis CA.

[0062] The protection portion 51 is continuous with the bearing portion 47. The protection portion 51 covers a portion of the wire harness 30 that extends from the bearing portion 47. The protection portion 51 has a protection wall portion 52 that covers at least a part of the wire harness 30 along the circumferential direction. Here, the protection wall portion 52 covers the entire circumference of the wire harness 30, and the protection portion 51 is formed in a cylindrical shape. The protection portion 51 may be cylindrical or square cylindrical. The protection wall portion 52 extends from the periphery of the insertion hole 50 formed at the center of the other of the pair of restriction wall portions 48.

[0063] 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 so as to be able to float along the extending direction. Thus, the wiring member 31 is less likely to be affected by the external force applied to the shaft-side protector 41 and the bearing-side protector 46.

[0064] The slider portion 54 is provided in the door-side section 34. The slider portion 54 protrudes from the outer surface of the protection wall portion 52. The slider portion 54 has a columnar portion that protrudes in a columnar shape from the outer surface of the protection wall portion 52. A circumferential groove is formed on the outer surface of the columnar portion. The slider portion 54 and the protection wall portion 52 may be integrally formed using a mold, or the slider portion 54 independently formed from the protection wall portion 52 may be later installed on the protection wall portion 52.

[0065] A first slider portion 54A and a second slider portion 54B are provided as the slider portion 54. The first slider portion 54A and the second slider portion 54B are connected by a slider holding portion so that the interval between the first slider portion 54A and the second slider portion 54B is kept constant. Here, it can be regarded as the slider holding portion. The first slider portion 54A and the second slider portion 54B are provided at positions separated from each other along the extending 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 the slider holding portion. The protective wall portion 52, which is the slider holding portion, covers and protects the section in 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 protection portion 51 may also 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.

[0066] A guide groove 58 is formed in the guide member 56, and the guide groove 58 guides the slider portion 54. The guide member 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 portion 54 moves along the guide groove 58 in the guide member 56. The inner peripheral edge of the guide groove 58 is fitted into the circumferential groove of the slider portion 54. The guide groove 58 has an opening / closing groove 59 and a stress absorption groove 62.

[0067] The opening / closing groove 59 has a first end portion 60 and a second end portion 61. The slider portion 54 is located at the first end portion 60 of the opening / closing groove 59 in the first open state. The opening / closing groove 59 is arranged such that when changing from the first open state to the closed state, the slider portion 54 moves from the first end portion 60 toward the second end portion 61 in the opening / closing groove 59. The first end portion 60 is located at a position in front of the vehicle relative to the second end portion 61. In the open state, the second end portion 61 is located at a position farther from the vehicle body support member 70 than the first end portion 60. In the closed state, the first end portion 60 is located at a position farther from the vehicle body support member 70 than the second end portion 61. In the opening / closing groove 59, the second end portion 61 is located at a position lower than the first end portion 60 along the vertical direction.

[0068] The stress absorption groove 62 extends from the first end portion 60 in a direction intersecting the extending direction of the opening / closing groove 59. The stress absorption groove 62 is arranged such that when changing from the first open state to the second open state, the slider portion 54 moves along the stress absorption groove 62. In the stress absorption groove 62, the end portion on the side opposite to the first end portion 60 is located at a position lower than the first end portion 60 along the vertical direction. The stress absorption groove 62 extends forward and downward of the vehicle from the first end portion 60. The stress absorption groove 62 is shorter than the opening / closing groove 59.

[0069] 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 an opening / closing groove 59 and a first stress absorption groove 62A as a stress absorption groove 62. The second guide groove 58B has a second opening / closing groove 59B as an opening / closing groove 59 and a second stress absorption groove 62B as a stress absorption groove 62. The first guide groove 58A is located above the second guide groove 58B.

[0070] The first opening / closing groove 59A has a first end portion 60A and a second end portion 61A. Here, the first opening / closing groove 59A is composed only of straight portions. The first opening / closing groove 59A extends linearly rearward and downward of the vehicle from the first end portion 60A toward the second end portion 61B. The first opening / closing groove 59A is shorter than the second opening / closing groove 59B.

[0071] The second opening / closing groove 59B has a first end portion 60B and a second end portion 61B. The second opening / closing groove 59B includes a curved portion 59B1. The second opening / closing groove 59B is composed of a combination of the curved portion 59B1 and a straight portion 59B2. In the second opening / closing groove 59B, the first end portion 60B side is the curved portion 59B1, and the second end portion 61B side is the straight portion 59B2. One end of the curved portion 59B1 is the first end portion 60B, one end of the straight portion 59B2 is the second end portion 61B, and the other end of the curved portion 59B1 is continuous with the other end of the straight portion 59B2.

[0072] The curved portion 59B1 extends in an arc shape centered on the first end portion 60A. Here, the curved portion 59B1 is shorter than a quarter circle (an arc of a quarter circle). The curved portion 59B1 may also be longer than a quarter circle. The straight portion 59B2 extends along the tangent direction of the other end of the curved portion 59B1 from the other end of the curved portion 59B1. The straight portion 59B2 is longer than each of the curved portion 59B1 and the first opening / closing groove 59A. The extending direction of the straight portion 59B2 is set to be a direction intersecting with the extending direction of the first opening / closing groove 59A. The first opening / closing groove 59A is inclined more with respect to the horizontal direction than the straight portion 59B2. The straight portion 59B2 extends linearly parallel to the horizontal direction rearward of the vehicle from the first end portion 60. The connecting portion of the curved portion 59B1 and the straight portion 59B2 is located directly below the first end portion 60A. The curved portion 59B1 extends forward of the vehicle from the connecting portion of the curved portion 59B1 and the straight portion 59B2 toward a position closer to the vehicle front than the first end portion 60A. The straight portion 59B2 extends rearward of the vehicle from the connecting portion of the curved portion 59B1 and the straight portion 59B2 toward a position closer to the vehicle rear than the first end portion 60A. The first end portion 60B is located in front of the vehicle compared to the first end portion 60A, and the second end portion 61B is located behind the vehicle compared to the first end portion 60A.

[0073] The first stress absorption groove 62A and the second stress absorption groove 62B are arranged to extend along a straight line. The second stress absorption groove 62B is located on the imaginary extension line obtained by hypothetically extending the first stress absorption groove 62A downward the vehicle. The first stress absorption groove 62A and the second stress absorption groove 62B have the same length.

[0074] Since the first slider portion 54A and the second slider portion 54B are held at a constant interval by the protective wall portion 52, Figure 7 as shown, the first slider portion 54A and the second slider portion 54B are interlocked while maintaining a constant interval. This interval is the interval 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 interval between the second end portion 61A and the second end portion 61B is also the same as the interval between the first end portion 60A and the first end portion 60B.

[0075] The posture 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 postures of the shaft side protector 41 and the end portions of the bellows 32 are determined by the posture of the bearing side protector 46. The bearing side protector 46 extends in the direction connecting the position of the first slider portion 54A and the position of the second slider portion 54B. The end portion of the bellows 32 supported by the bearing side protector 46 via the shaft side protector 41 extends along the extension direction of the bearing side protector 46.

[0076] 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 the 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 can be, for example, a spring such as a helical spring, a disc spring, or a constant load spring. A biasing portion support portion 65 for supporting one end of the biasing portion 64 is provided on the slider portion 54. The other end of the biasing portion 64 is supported by, for example, the guide body 57 or the like.

[0077] 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. Thereby, 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 biased toward the first end portion 60 along the extension direction of the first opening / closing groove 59A.

[0078] The vehicle body support member 70 supports the vehicle body side section 33 on the vehicle body 10 at a position adjacent to the floating section 35 in the vehicle body side section 33. The vehicle body support member 70 has a pipe holding section 71. The pipe holding section 71 supports the bellows 32 at a constant position along the extending direction. The pipe holding section 71 can support the bellows 32 so as to be rotatable about the central axis CA, or can support the bellows 32 so as not to be rotatable. The vehicle body support member 70 is installed on the vehicle body 10 at a constant position. Thereby, the vehicle body 10 side end portion of the bellows 32 is held at a constant position on the vehicle body 10. The vehicle body support member 70 is supported on the vehicle body 10 in a non-rotatable manner. Thereby, the direction in which the vehicle body 10 side end portion of the bellows 32 extends from the vehicle body support member 70 is maintained as a constant direction. The vehicle body support member 70 can also be supported on the vehicle body 10 in a rotatable manner in order to be able to perform a nodding motion for changing the extending direction of the end portion of the bellows 32.

[0079] In each of one end portion and the other end portion of the bellows 32, a plurality of large-diameter cylindrical portions and small-diameter cylindrical portions of a plurality of periodic amounts are respectively held by the pipe holding sections 43 and 71. Therefore, in each of one end portion and the other end portion of the bellows 32, the bending of the bellows 32 is restricted by the pipe holding sections 43 and 71.

[0080] The vehicle body side connector 37 at one end of the wiring member 31 is positioned and fixed to the vehicle body 10 by being connected to a vehicle body side device. The pipe holding section 71 of the vehicle body support member 70 positions and fixes the bellows 32 along the extending direction. The wiring member 31 is not fixed to the bellows 32, and thus is not positioned and fixed to the pipe holding section 71. A fixing section for positioning and fixing the wiring member 31 to the vehicle body 10 may also be provided between the vehicle body side connector 37 and the pipe holding section 71.

[0081] The door side connector 38 at the other end of the wiring member 31 is positioned and fixed to the sliding door 12 by being connected to a door side device. The portion of the wiring member 31 passing through the shaft side protector 41 and the bearing side protector 46 can float relative to the protectors 41 and 46 and move relative to the sliding door 12, and thus is not positioned and fixed to the sliding door 12. A fixing section 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.

[0082] <Regarding the operation of the slider portion and the deformation of the floating section>

[0083] The operation of the slider portion 54 and the deformation of the floating section 35 will be described in more detail.

[0084] When changing the state between the first open state and the closed state by the opening and closing operation of the sliding door 12, the first slider portion 54A moves along the first opening and closing groove 59A, and the second slider portion 54B moves along the second opening and closing groove 59B. When the second slider portion 54B moves on the curved portion 59B1 from the first end portion 60B toward the second end portion 61B, the first slider portion 54A stays at the first end portion 60A until the second slider portion 54B reaches the straight portion 59B2. When the second slider portion 54B moves in the straight portion 59B2, the first slider portion 54A moves in the first opening and closing groove 59A. More specifically, in Figure 7 when the second slider portion 54B moves in the curved portion 59B1 along the direction of the arrow OC2A, the first slider portion 54A stays at the first end portion 60A and rotates. In Figure 7 when the second slider portion 54B moves in the straight portion 59B2 along the direction of the arrow OC2B, the first slider portion 54A moves in the first opening and closing groove 59A along the direction of the arrow OC1. At this time, since a rotational movement is also applied, the distance that the first slider portion 54A moves along the first opening and closing groove 59A is shorter than the distance that the second slider portion 54B moves along the straight portion 59B2.

[0085] In the first open state, most of the sliding door 12 is located at a position rearward of the vehicle compared to the boarding and alighting opening 11. Along with this, the shaft side protector 41 is located at a position rearward of the vehicle compared to the vehicle body support member 70. At this time, the bearing side protector 46 extends in the direction connecting the first end portion 60A and the first end portion 60B, and the bellows 32 extends from the shaft side protector 41 toward the front and downward of the vehicle.

[0086] In the closed state, the sliding door 12 closes the boarding and alighting opening 11. Along with this, the shaft side protector 41 is located at a position forward of the vehicle compared to the vehicle body support member 70. At this time, the bearing side protector 46 extends in the direction connecting the first slider portion 54A near the second end portion 61A and the second slider portion 54B near the second end portion 61B, and the bellows 32 extends from the shaft side protector 41 toward the rear and downward of the vehicle.

[0087] In the closed state, the first slider portion 54A and the second slider portion 54B are respectively located in the linear groove portion. Thus, in the closed state, when a force is applied to the first slider portion 54A toward the first end portion 60A, the first slider portion 54A and the second slider portion 54B are likely to move toward the first end portion 60A and the first end portion 60B. Here, in the closed state, slack may occur in the floating section 35. In this case, by the first slider portion 54A and the second slider portion 54B moving toward the first end portion 60A and the first end portion 60B, the floating section 35 is also likely to be in a state where tension is moderately applied, and it is difficult for slack to occur in the floating section 35. Thus, in the closed state, the portion extending outward from the vehicle door interior trim 14 in the floating section 35 is difficult to be exposed to the interior space of the vehicle.

[0088] When a stepping load F is applied to or removed from the exposed section 36 to change the state 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 Figure 7 it, when the second slider portion 54B moves in the second stress absorption groove 62B in the direction of arrow SL2, the first slider portion 54A moves in the first stress absorption groove 62A in the direction of arrow SL1.

[0089] For example, the exposed section 36 is located above a rigid member (such as the support arm 15 or the step portion of the vehicle) of the vehicle. For example, the length of the stress absorption groove 62 can be set such that the exposed section 36 to which the stepping load F is applied can move to the rigid member. After the exposed section 36 to which the stepping load F is applied reaches the rigid member, the rigid member supports the exposed section 36 from below, so that it is difficult for the stepping load F to act as the tension of the wire harness 30. By having the rigid member, it is possible to prevent the exposed section 36 to which the stepping load F is applied from moving downward more than the step.

[0090] The length of the stress absorption groove 62 can also take into account the elongation deformation of the bellows 32 externally mounted on the exposed section 36. The length of the stress absorption groove 62 can be shortened corresponding to the elongation deformation of the bellows 32.

[0091] In the second open state, the first slider portion 54A and the second slider portion 54B are respectively located in the linear groove portion. Thus, in the second open state, when the stepping load F is eliminated and the first slider portion 54A is urged toward the first end portion 60A, the first slider portion 54A and the second slider portion 54B are likely to move toward the first end portion 60A and the first end portion 60B. Therefore, when the stepping load F is eliminated, the first slider portion 54A and the second slider portion 54B are likely to return to the first end portion 60A and the first end portion 60B by the action of the urging portion 64.

[0092] The angle formed by the extending direction of the first stress absorption groove 62A and the vertical direction is smaller than the angle formed by the extending direction of the first opening / closing groove 59A and the vertical direction. Therefore, regarding the action force of the urging portion 64 when the first slider portion 54A moves the same distance along the first stress absorption groove 62A and the first opening / closing groove 59A from the first end portion 60, the force is larger when moving in the first stress absorption groove 62A.

[0093] The wiring member 31 is not fixed to the bellows 32 and the protectors 41, 46 and can float along the extending direction with respect to the bellows 32 and the protectors 41, 46. When the above state changes, the bellows 32 and the protectors 41, 46 first change their postures, and the wiring member 31 is pressed by the bellows 32 and the protectors 41, 46 and changes its posture in a manner to follow the bellows 32 and the protectors 41, 46. At this time, the portions of the bellows 32 and the protectors 41, 46 that press the wiring member 31 change appropriately. Even in this case, since the wiring member 31 floats in the extending direction with respect to the bellows 32 and the protectors 41, 46, it is possible to suppress the tension of the portion of the wiring member 31 pressed by the bellows 32 and the protectors 41, 46 from becoming excessive.

[0094] <Effects, etc.>

[0095] According to the door support member 40 configured as described above and the wiring structure 20 of the wiring harness including the door support member 40, when a stepping load F is applied to the exposed section 36, the slider portion 54 moves along the stress absorption groove 62, so that it is difficult to apply an excessive stress to the wiring harness 30. Thus, even when a stepping load F is applied to the exposed section 36 between the sliding door 12 and the vehicle body 10 in the wiring harness 30, it is possible to suppress the application of a large tension to the wiring harness 30.

[0096] In addition, the door support member 40 has an urging portion 64 that urges the slider portion 54 toward the opening / closing groove 59 along the extending direction of the stress absorption groove 62. Thus, when the stepping load F is eliminated, the slider portion 54 can return to the first end portion 60 by the action of the urging portion 64. In addition, the action force of the urging portion 64 can become a resistance against the stepping load F.

[0097] In addition, the force applying portion 64 applies force to the slider portion 54 toward the first end portion 60 along the extending direction of the opening and closing groove 59, and in the closed state, the first end portion 60 is located at a position farther from the vehicle body support member 70 than the second end portion 61. As a result, the portion of the floating section 35 connected to the slider portion 54 is easily hidden in the slide door 12 in the closed state, and is difficult to be exposed from between the slide door 12 and the vehicle body 10. In addition, even in the closed state, when the space for the floating section 35 in which the wire harness 30 can be arranged between the vehicle body 10 and the slide door 12 is small, it is easy to apply the wiring structure 20 of the wire harness. Here, the connection portion of the floating section 35 of the wire harness 30 connected to the vehicle body side section 33 can also be arranged at a position closer to the inside than the weather strip 16. In this case, when the weather strip 16 is arranged in a manner of doubly surrounding the door trim 14, the space for arranging the floating section 35 between the vehicle body 10 and the slide door 12 in the closed state becomes small.

[0098] In addition, in the first opening and closing groove 59A, the second end 61A is located at a position lower than the first end 60A in the vertical direction, and in the first stress absorbing groove 62A, the end on the side opposite to the first end 60A is located at a position lower than the first end 60A in the vertical direction, and the force applying portion 64 applies force to the first slider portion 54A upward in the vertical direction. Thus, when the first slider portion 54A moves along the first opening and closing groove 59A and when the first stress absorbing groove 62A moves, the force applying portion 64 easily applies force to the first slider portion 54A toward the first end 60A. In addition, during the opening and closing of the slide door 12, the first slider portion 54A is forced toward the first end 60A, thereby suppressing the droop of the floating section 35.

[0099] In addition, two sets of the slider portion 54 and the guide groove 58 are provided, namely, a set of the first slider portion 54A and the first guide groove 58A and a set of the second slider portion 54B and the second guide groove 58B. Thus, the door side section 34 can be guided more smoothly as the sliding door 12 is opened and closed, and the floating section 35 connected to the door side section 34 can also change its posture more smoothly.

[0100] The first stress absorbing groove 62A and the second stress absorbing groove 62B are provided so as to extend along a straight line. Thus, when a stepping load F is applied to the exposed section 36 , the stepping load F can be smoothly guided to the door side section 34 .

[0101] In addition, the first opening and closing groove 59A is shorter than the second opening and closing groove 59B. This can prevent the space required for the guide member 56 from increasing in the slide door 12 .

[0102] In addition, the door support member 40 includes a slider holding portion that connects the first slider portion 54A and the second slider portion 54B and maintains a constant interval between the first slider portion 54A and the second slider portion 54B. Thereby, the first slider portion 54A and the second slider portion 54B can move along the guide groove 58 while maintaining a constant interval respectively.

[0103] The slider holding portion covers and protects the portion from the part where the first slider portion 54A is provided to the part where the second slider portion 54B is provided in the door side section 34. Thereby, the slider holding portion can be used as a protector.

[0104] In addition, by externally mounting the bellows 32 outside the floating section 35, the stepping load F on the floating section 35 is transmitted to the wire harness 30 via the bellows 32. At this time, the wire harness 30 can float in the extending direction with respect to the bellows 32 and the protector, so that the wire harness 30 can follow the elongation deformation of the bellows 32. Thereby, even when a stepping load F is applied to the floating section 35, an increase in the tension of the wire harness 30 can be suppressed.

[0105] In addition, one end portion of the bellows 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 posture of the bellows 32 changes as the sliding door 12 opens and closes, a torque about the central axis CA may be applied to the bellows 32. Even in this case, by rotating the bellows 32 about the central axis CA with respect to the protector, the torque applied to the bellows 32 can be absorbed.

[0106] [Remarks of Embodiment 1]

[0107] Figure 8 It is a figure showing a modification example of the shaft side protector 41 and the bearing side protector 46.

[0108] The modified shaft side protector 141 is a member formed by combining the first divided member 141X and the second divided member 141Y, and the first divided member 141X and the second divided member 141Y have a shape in which the portion through which the wire harness 30 passes is divided along the axial direction. Similarly, the modified bearing side protector 146 is a member formed by combining the first divided member 146X and the second divided member 146Y, and the first divided member 146X and the second divided member 146Y have a shape in which the portion through which the wire harness 30 passes is divided along the axial direction. Thereby, the post-installation of the shaft side protector 141 and the bearing side protector 146 with respect to the wire harness 30 and the bellows 32 becomes easy. The first divided members 141X, 146X and the second divided members 141Y, 146Y may be in a shape divided into halves, or may be in a shape divided in a ratio other than that.

[0109] In the split parts 146X and 146Y of the bearing-side protector 146, the part that forms the bearing part 47 has ribs. Recesses are formed on the ribs. The ribs and recesses of the two split parts 146X and 146Y are aligned to form the above-mentioned restricting wall part 48 and the insertion through-hole 50. Here, the protective part 51 of the bearing-side protector 146 extends not from the periphery of the recess in the rib but from the outer edge. When the shaft-side protector 141 rotates, the part of the wiring member 31 that extends from the shaft-side protector 141 is held by the peripheral part of the insertion through-hole 50.

[0110] The fixing parts of the first split parts 141X and 146X and the second split parts 141Y and 146Y are fixed by threads or the like. The fixing parts of the first split parts 141X and 146X and the second split parts 141Y and 146Y have rigidity such that the cylindrical shapes of the shaft part 44 and the bearing part 47 will not be deformed even when torque of the bellows 32 or the like is applied.

[0111] In addition, in this modified example, the pipe holding part 143 of the shaft-side protector 141 covers the bellows 32. Thus, the pipe holding part 143 can be installed on the outer periphery of the bellows 32. The pipe holding part 143 in the split parts 141X and 141Y has a convex part that projects toward the inner surface of the part that forms the cylindrical main body 42. The convex parts of the two split parts 141X and 141Y are aligned to form an annular convex part, which is fitted on the outside of the small-diameter cylindrical part.

[0112] In the bearing-side protector 146, the slider part 54 may not be split and may be provided on either the first split part 146X or the second split part 146Y. The split slider parts 54 may also be provided on the first split part 146X and the second split part 146Y respectively.

[0113] In addition, so far, the case where the slider part 54 is provided on the bearing-side protector 46 has been described, but this is not an essential structure. The slider part may also be provided on the wire harness via a member different from the bearing-side protector 46.

[0114] In addition, so far, it has been described that the door support member 40 includes the shaft-side protector 41 and the biasing part 64, but this is not an essential structure. The shaft-side protector 41 and the biasing part 64 may also be omitted.

[0115] In addition, so far, the case where two sets of slider parts 54 and guide grooves are provided has been described, but this is not an essential structure. Only one set of slider parts and guide grooves may also be provided. In the following Embodiment 2, an example where only one set of slider parts and guide grooves is provided will be described.

[0116] [Embodiment 2]

[0117] Figure 9is a schematic top view showing the wiring structure 220 of the wire harness according to Embodiment 2. In addition, in Figure 9 the door support member 240 shown by the solid line is in the first open state, and the door support member 240 shown by the double-dashed line is in the closed state. Figure 10 is a schematic front view showing the second open state. Figure 11 is a cross-sectional view taken along the Figure 10 XI-XI line. In the following description, the parts different from those of Embodiment 1 will be mainly described, and the same reference numerals will be given to the same matters as those of Embodiment 1, and the detailed description thereof will sometimes be omitted.

[0118] In the wiring structure 220 of the wire harness, the structure of the door support member 240 is different from the structure of the above-described door support member 40. Specifically, in the door support member 240, only one set of the slider portion 254 and the guide groove 258 is provided along the extending direction of the door side section 34. Here, the guide groove 258 is a groove provided in such a manner that the opening / closing groove 259 and the stress absorbing groove 262 are connected to each other. Here, only one guide groove 258 corresponding to the above-described first guide groove 58A is provided in the guide member 256. In the guide member 256, no groove for guiding the slider portion 254 of the door side section 34 is provided except for one guide groove 258. The slider portion 254 guided by the guide groove 258 is provided only at one position along the extending direction of the door side section 34.

[0119] As Figure 11 shown, the slider portion 254 has an inner slider portion 254A and an outer slider portion 254B that project in opposite directions from the same position along the extending direction of the door side section 34 in the vehicle's inner and outer directions. The guide member 256 has an inner guide plate portion 257A provided at a position closer to the vehicle interior than the door side section 34 and an outer guide plate portion 257B provided at a position closer to the vehicle exterior than the door side section 34. The guide groove 258 has an inner guide groove 258A formed in the inner guide plate portion 257A for engaging the inner slider portion 254A, and an outer guide groove 258B formed in the outer guide plate portion 257B for engaging the outer slider portion 254B. 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 extending direction of the door side section 34. Therefore, in this case, although there are two sets of the slider portion 254 and the guide groove 258 in the vehicle's inner and outer directions, it can be regarded as only one set being provided along the extending direction of the door side section 34.

[0120] The guide member 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, and are thus held at a constant interval along the inner and outer directions of the vehicle.

[0121] In this example, the door support member 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 vehicle interior, and the outer slider portion 254B protrudes from the surface facing the vehicle exterior.

[0122] The inner slider portion 254A and the outer slider portion 254B are not respectively provided with recesses that fit into the peripheral portions of the corresponding guide grooves 258 in the guide plate portions 257A and 257B. The side surfaces of the inner slider portion 254A and the outer slider portion 254B are formed in the shape of a cylindrical side surface or a frustum side surface. In this case, by fitting the inner slider portion 254A into the inner guide groove 258A and the outer slider portion 254B into the outer guide groove 258B, it is also possible to prevent the inner slider portion 254A and the outer slider portion 254B from coming off from the corresponding guide grooves 258A and 258B respectively.

[0123] In the wiring structure 220 of the wire harness, along the extending direction of the door side section 34, there is no slider portion 254 other than the slider portion 254 that fits into the guide groove 258. In the wiring structure 220 of the wire harness, a second slider portion other than the slider portion 254 may also be provided. In this case, a groove for fitting the second slider portion may or may not be provided in the guide member 256. However, when a groove for fitting the second slider portion is provided in the guide member 256, the groove may be configured not to have both the opening / closing groove 259 and the stress absorbing groove 262. The groove may be configured to guide only one of the state changes between the closed state and the first open state and the state change between the first open state and the second open state. For example, the groove may also be configured to have only one of the opening / closing groove 259 and the stress absorbing groove 262.

[0124] 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 the guide member 256 with the slider portion 254 at the upper end as the rotation axis. For example, when the sliding door 12 is opened and closed, the protector 246 rotates by being pulled by the wire harness 30 at the lower end.

[0125] In this example, the door support member 240 for the door also includes a biasing portion 264. The biasing portion 264 biases the slider portion 254 in the same manner as the above-described biasing portion 64. The biasing portion 264 and the slider portion 254 are connected by a connecting portion (not shown).

[0126] The sliding door 12 includes a door main body 13A and a protruding portion 13B that protrudes inward from the lower portion of the door main body 13A. For example, the door main body 13A and the protruding portion 13B are different parts of the door panel 13. The guide member 256 is located above the protruding portion 13B and is attached to the door main body 13A. The protector 246 has: a first protection portion 251A that covers the portion of the door-side section 34 where the slider portion 254 is provided; and a second protection portion 251B that extends downward and inward from the first protection portion 251A. The second protection portion 251B covers the section closer to the vehicle body-side connector 37 than the first protection portion 251A.

[0127] As Figure 11 shown, the second protection portion 251B offsets the upper and lower ends of the protector 246 in the vehicle's inside-outside direction. For example, the second protection portion 251B may extend outside the guide member 256 in the first open state. Additionally, for example, the protruding portion 13B may be located at a height lower than that of the second protection portion 251B in the first open state. Thereby, in the first open state, the portion of the wiring harness 30 extending from the protector 246 can pass through a position closer to the inside of the vehicle than the protruding portion 13B, suppressing contact between this portion and the protruding portion 13B. Additionally, for example, the protruding portion 13B may be provided at a position that becomes the same height as the second protection portion 251B in the second open state. Thereby, in the second open state, the protector 246 can pass through a position closer to the inside of the vehicle than the protruding portion 13B, suppressing contact between the protector 246 and the protruding portion 13B.

[0128] In Figure 9 the example shown, a supported portion 34A is provided at a position on the door-side connector 38 side of the door-side section 34 that is closer to the door than the position where the slider portion 254 is provided. The supported portion 34A is supported by the guide member 256. As the slider portion 254 moves along the guide groove 258 or the protector 246 rotates about the slider portion 254 as a rotation axis, the portion between the portion of the door-side section 34 where the slider portion 254 is provided and the supported portion 34A deforms. The supported portion 34A may be supported by the guide member 256 so as to be rotatable about an axis along the vehicle's inside-outside direction. The door support member 240 may also have a rotary support member 66 that holds the supported portion 34A and is rotatably supported by the guide member 256.

[0129] <Effects, etc.>

[0130] According to the wiring structure 220 of the wiring harness, effects other than the effects brought about by providing a plurality of guide grooves 58 having opening / closing grooves 59 and stress absorption grooves 62 in the guide member 56 can also be obtained, which are the same as those of the wiring structure 20 of the above-mentioned wiring harness.

[0131] In addition, according to the wiring structure 220 of the wiring harness, only one guide groove 258 for fitting the slider portion 254 and having an opening / closing groove 259 and a stress absorption groove 262 is provided in the guide member 256. Therefore, compared with the case of the first embodiment in which a plurality of guide grooves 58 having opening / closing grooves 59 and stress absorption grooves 62 are provided in the guide member 56, the enlargement of the guide member 256 can be suppressed in the direction along the main surface of the sliding door 12.

[0132] In addition, slider portions 254A and 254B and guide grooves 258A and 258B are provided on both sides in the vehicle interior / exterior direction. Therefore, it is easy to suppress the detachment of the slider portions 254A and 254B from the guide grooves 258A and 258B. In addition, it is easy to make the inner slider portion 254A and the outer slider portion 254B into simple shapes. For example, a concave portion for fitting the peripheral portion of the inner guide groove 258A in the inner guide plate portion 257A is not formed in the inner slider portion 254A. Similarly, a concave portion for fitting the peripheral portion of the outer guide groove 258B in the outer guide plate portion 257B is not formed in the outer slider portion 254B.

[0133] In addition, along the extending direction of the door side section 34, no slider portion other than the slider portion 254 fitted in the guide groove 258 is provided. Thereby, the complication of the structure of the door support member 240 can be suppressed.

[0134] In addition, 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. Therefore, compared with the door support member 40 in which slider portions 54 are provided at the upper end and the lower end of the protector 41 respectively, the enlargement of the door support member 240 can be suppressed.

[0135] In addition, the sliding door 12 includes a protruding portion 13B, the guide member 256 is located above the protruding portion 13B, and the protector 246 has a first protection portion 251A and a second protection portion 251B. Thereby, the guide member 256 is accommodated above the protruding portion 13B in the sliding door 12, and the situation where the lower part of the door side section 34 contacts the protruding portion 13B is suppressed by the second protection portion 251B.

[0136] [Supplementary Notes of Embodiment 2]

[0137] Figure 12 It is a schematic top view showing a modified example of the wiring structure 20 of the wiring harness. Figure 13 It is along Figure 12Cross-sectional view taken along line XIII-XIII.

[0138] In Figure 12 In the wiring structure 320 of the harness shown, there is also only provided a set of a guide groove 358 having an opening / closing groove 359 and a stress absorption groove 362, and a slider portion 354 fitted into the guide groove 358. In the wiring structure 320 of the harness, a slider portion 355 that is not fitted into the guide groove is provided independently of the slider portion 354.

[0139] Specifically, the door support member 340 in the wiring structure 320 of the harness includes a lower slider portion 355, and the lower slider portion 355 is provided at a position lower than the slider portion 354 along the extending direction of the door side section 34. The guide member 356 is not provided with a groove for fitting the lower slider portion 355. The lower slider 355 is guided along the lower edge of the guide member 356 between the first open state and the closed state. The lower edge of the guide member 356 is formed, for example, in a shape corresponding to the upper peripheral portion of the above-described second guide groove 58B. Thus, between the first open state and the closed state, in addition to the set of the slider portion 354 and the guide groove 358, the harness 30 can also be guided by the set of the lower slider portion 355 and the lower edge of the guide member 356. In addition, by not providing a guide groove corresponding to the lower slider portion 355, the enlargement of the guide member 356 can be suppressed. The structure in which the lower slider 355 is guided along the lower edge of the guide member 356 can also be applied to the guide member 256 in the wiring structure 220 of the above-described harness.

[0140] The present disclosure can be understood as a wiring structure of a harness. When the sliding door changes its state between the open state and the closed state, the slider portion 254 moves along the groove of the guide member 256, and there is only provided a set of the slider portion 254 and the groove along the extending direction of the door side section. According to this method, the enlargement of the guide member 256 can be suppressed in the direction along the main surface of the sliding door.

[0141] In addition, the respective structures described in the above-described embodiments and respective modification examples can be appropriately combined as long as they do not contradict each other.
