[0013] [Description of Embodiments of the Present Disclosure]

[0014] First, embodiments of the present disclosure will be listed and described.

[0015] The wiring structure of the wiring harness of the present disclosure is as follows.

[0016] A wiring structure of a wiring harness that connects a device provided on a vehicle body and a device provided on a movable body, where the movable body slides relative to the vehicle body. The wiring structure of the wiring harness includes: a wiring harness including a wiring member and a corrugated tube, the corrugated tube being externally mounted on the wiring member. The wiring harness has a vehicle body side section, a movable body side section, and a floating section. The vehicle body side section is supported by the vehicle body, the movable body side section is supported by the movable body, and the floating section is located between the vehicle body side section and the movable body side section; a vehicle body support member that supports the corrugated tube in the vehicle body side section on the vehicle body; and a movable body support member that supports the corrugated tube in the movable body side section on the movable body. At least one of the vehicle body support member and the movable body support member includes a shaft side protector and a bearing side protector. The shaft side protector has a shaft portion and a tube holding portion, and the bearing side protector has a bearing portion. The tube holding portion holds the corrugated tube with the central axes aligned. The shaft side protector is supported by the bearing side protector in a rotatable manner about the central axis via the bearing portion and the shaft portion, each having a cylindrical peripheral surface around the central axis. The bearing side protector is supported by the vehicle body or the movable body.

[0017] According to the wiring structure of the wiring harness in (1), when a torque about the central axis is applied to the corrugated tube, the corrugated tube is subjected to the torque and rotates about the central axis relative to the bearing side protector via the shaft side protector, thereby being able to absorb the torque. In addition, since the shaft portion and the bearing portion each have a cylindrical peripheral surface, compared with the case of supporting using spherical members, the structure of the support member can be simplified and the support member can be reduced in size.

[0018] (2) In the wiring structure of the wiring harness in (1), it may also be that the tube holding portion covers the corrugated tube. Thus, the tube holding portion can be mounted on the outer periphery of the corrugated tube.

[0019] (3) In the wiring structure of the wiring harness in (1), it may also be that the corrugated tube covers the tube holding portion. Thus, the corrugated tube can be mounted on the outer periphery of the tube holding portion.

[0020] (4) In the wiring structure of the wire harness according to any one of (1) to (3), it is also possible that the tube holding portion has a concavo-convex shape corresponding to the concavo-convex of the bellows, the shaft portion has a flange, the flange projects along the radial direction of the central axis compared with the tube holding portion, and an annular recess is formed in the bearing portion, and the flange is fitted into the annular recess. Thus, the shaft-side protector and the bearing-side protector can be made into simple shapes, and the shaft-side protector can rotate smoothly relative to the bearing-side protector.

[0021] (5) In the wiring structure of the wire harness according to any one of (1) to (4), it is also possible that the bearing-side protector has a protection portion, the protection portion is continuous with the bearing portion on the side opposite to the floating section along the extension direction of the wire harness, and covers the wire harness. Thus, the wire harness can be protected by the bearing-side protector.

[0022] (6) In the wiring structure of the wire harness according to any one of (1) to (5), it is also possible that the shaft-side protector and the bearing-side protector are respectively components formed by combining a first split member and a second split member, and the first split member and the second split member have a shape split along the axial direction. Thus, it becomes easy to install the shaft-side protector and the bearing-side protector relative to the wire harness and the bellows later.

[0023] (7) In the wiring structure of the wire harness according to any one of (1) to (6), it is also possible that the wiring member is inserted through the bellows in a manner capable of floating along the extension direction. Thus, when the bellows and the shaft-side protector rotate relative to the bearing-side protector and the bellows twists, the wiring member inside the bellows is difficult to twist.

[0024] (8) In the wiring structure of the wire harness according to any one of (1) to (7), it is also possible that the movable body is a sliding door. Thus, the torque applied to the bellows during the opening and closing of the sliding door can be absorbed by the shaft-side protector and the bearing-side protector.

[0025] (9) In the wiring structure of the wire harness in (8), it is also possible that the movable body support member includes the shaft-side protector, the bearing-side protector, and a guide member, the guide member is formed with a guide groove, the bearing-side protector has a slider portion, and the slider portion is supported by the guide member in a manner capable of sliding along the guide groove as the sliding door opens and closes. Thus, when the sliding door opens and closes, the portion of the bellows mounted on the shaft-side protector slides along the guide groove together with the bearing-side protector and the shaft-side protector. In this way, even when the bellows slides relative to the sliding door together with the bearing-side protector and the shaft-side protector and torque is applied to the bellows, the torque applied to the bellows during the opening and closing of the sliding door can be absorbed.

[0026] In the wiring structure of the wiring harness according to any one of (1) to (7), the movable body may be a seat. Thereby, the torque applied to the bellows when the seat slides can be absorbed by the shaft side protector and the bearing side protector.

[0027] (11) In addition, the support member of the present disclosure supports the vehicle body side section or the movable body side section in the wiring harness on the vehicle body or the movable body. The wiring harness includes a wiring member and a bellows, the bellows is externally mounted on the wiring member, the wiring harness is provided with the vehicle body side section, the movable body side section, and a floating section. The vehicle body side section is supported on the vehicle body, the movable body side section is supported on the movable body that slides relative to the vehicle body, and the floating section is located between the vehicle body side section and the movable body side section. Among them, the support member includes: a shaft side protector including a shaft portion and a tube holding portion; and a bearing side protector including a bearing portion. The tube holding portion holds the bellows in a manner that the central axes coincide. The shaft side protector is supported on the bearing side protector in a rotatable manner around the central axis via the bearing portion and the shaft portion each having a cylindrical peripheral surface around the central axis, and the bearing side protector is supported on the vehicle body or the movable body.

[0028] According to the support member of (11), when a torque around the central axis is applied to the bellows, the bellows receives this torque and rotates around the central axis relative to the bearing side protector via the shaft side protector, thereby being able to absorb this torque. In addition, since the shaft portion and the bearing portion each have a cylindrical peripheral surface, compared with the case of supporting using spherical members, the structure of the support member can be simplified, and the support member can be reduced in size.

[0029] [Details of the embodiments of the present disclosure]

[0030] A specific example of the wiring structure of the wiring harness of the present disclosure will be 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.

[0031] [Embodiment 1]

[0032] Hereinafter, the wiring structure of the wiring harness of Embodiment 1 will be described. In the present embodiment, Figure 1 An example in which the movable body is a sliding door will be used for description. Figure 1 It is a schematic plan view showing the wiring structure 20 of the wiring harness. Figure 1 The shown front-rear direction (front, rear) and up-down direction (up, down) correspond to the front-rear direction and up-down direction of the vehicle. Figure 1 The shown inner-outer direction (inner, outer) corresponds to the inner-outer direction in the left-right direction of the vehicle with respect to the side surface of the vehicle. Specifically, inFigure 1 In [description], the right side part of the vehicle is shown. The left side of the right side surface of the vehicle is the inner side of the vehicle, and the right side of the right side surface of the vehicle is the outer side of the vehicle.

[0033] First, the relationship between the wiring structure 20 of the wiring harness and the vehicle body 10 and the sliding door 12 to which the wiring structure 20 is applied will be described. In addition, in Figure 1 [description], the wiring structure 20 of the wiring harness shown by the solid line indicates the state where the sliding door 12 is open, and the wiring structure 20 of the wiring harness shown by the double-dot dash line indicates the state where the sliding door 12 is closed. In addition, in Figure 1 [description], for some components such as the sliding door 12, both the open state and the closed state are indicated by the double-dot dash line.

[0034] In the vehicle body 10, an opening 11 for passengers to get on and off is provided on the side surface. The sliding door 12 is supported by the vehicle body 10 in a slidable manner. By sliding the sliding door 12, the opening 11 for passengers to get on and off is opened and closed. The sliding door 12 includes a door panel 13 forming the appearance of the sliding door 12 and a door interior 14 provided on the inner side of the door panel 13. For example, a support arm 15 supporting the sliding door 12 is supported by a support rail arranged on the vehicle body 10 in a slidable manner. A sealing strip 16 is arranged on the periphery of the opening 11 for passengers to get on and off in contact with the door panel 13 and the vehicle body 10. For example, the sealing strip 16 is arranged in a ring shape on the outer peripheral side of the door interior 14 in the state where the sliding door 12 is closed.

[0035] On the sliding door 12, for example, a door side device such as an electric window is provided. This door side device is connected to a vehicle body side device (such as an ECU, etc.) 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 connecting the vehicle body side device and the door side device; a door support member 40 supporting the wiring harness 30 on the sliding door 12; and a vehicle body support member 70 supporting the wiring harness 30 on the vehicle body 10.

[0036] The wiring harness 30 includes: a wiring member 31 transmitting power or signals between the door side device and the vehicle body side device; and a corrugated pipe 32 externally covering the wiring member 31. The wiring member 31 is, for example, an electric wire or an optical fiber cable, etc. The wiring member 31 can be one or a plurality. The corrugated pipe 32 protects the wiring member 31 or collects a plurality of wiring members 31. The corrugated pipe 32 has a shape in which a large-diameter cylindrical portion and a small-diameter cylindrical portion having circular cross-sections are alternately continuous. On the outer surface and the inner surface of the corrugated pipe 32, the concave and convex shapes corresponding to the large-diameter cylindrical portion and the small-diameter cylindrical portion are continuous along the extending direction. In addition, in Figure 1In this case, the end portion in the bellows 32 is described as a shape that conforms to the original shape of the bellows 32 having a concavo-convex shape, while the middle portion of the bellows 32 is simply described as a shape in which the concavo-convex shape is omitted. In Figure 2 The same applies to the subsequent figures.

[0037] 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 floating section 35 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 wire harness 30.

[0038] The vehicle body side section 33 is supported by the vehicle body 10 through a vehicle body support member 70. The vehicle body side section 33 is held by the vehicle body 10 when the sliding door 12 is opened and closed. The vehicle body side section 33 is disposed, 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 through which the wire harness 30 is led out to the periphery of the boarding / alighting opening 11 is provided in the vehicle body 10. Figure 1 The illustrated vehicle body support member 70 supports, at the periphery of 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 outward from the vehicle body 10 through the vehicle body side wire harness opening.

[0039] The door side section 34 is a section supported by the sliding door 12 through a door support member 40. The door side section 34 is held by 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 disposed between the door panel 13 and the door trim 14 to suppress exposure. A door side wire harness opening through which the wire harness 30 is led out is provided in the door trim 14. The door side wire harness opening is provided, for example, at the lower part of the door trim 14. The floating section 35 extends outward from the sliding door 12 through the door side wire harness opening.

[0040] The 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. 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.

[0041] The floating section 35 has an exposed section 36. The exposed section 36 is the section that is exposed between the vehicle body 10 and the sliding door 12 when the sliding door 12 is open. Here, the bellows 32 provided in the floating section 35 is exposed. For example, the exposed section 36 is the portion between the vehicle body side wire harness opening and the door side wire harness opening in the floating section 35.

[0042] The exposed section 36 is exposed at a position as much as possible where it is difficult to interfere with the occupants getting on and off the vehicle, such as at the rear and lower positions in the boarding and alighting opening 11. However, since the exposed section 36 is exposed in the boarding and alighting opening 11, it is difficult to completely eliminate the situation where the occupants getting on and off the vehicle step on it through the boarding and alighting opening 11. 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 becoming large.

[0043] 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 the 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.

[0044] 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 sectional view taken along line IV-IV of 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 trajectory of the slider portion 54.

[0045] In the wire harness 30, the wiring member 31 is inserted through the corrugated tube 32 in a manner that allows it to float along the extending direction. Thus, the wiring member 31 is hardly affected by the external force applied to the corrugated tube 32. Specifically, the wiring member 31 only 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 twists, it is difficult for the wire harness 30 to twist. In addition, the corrugated tube 32 bends in such a way that when it is pressed in a direction crossing the axial direction at the middle part, it is pulled in the pressed direction, and the difference between the concave and convex parts 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 corrugated tube 32, it floats along the extending direction, thereby suppressing the tension applied to the wiring member 31 from becoming large.

[0046] 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.

[0047] 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 corrugated tube 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 along the axial center direction, and a shaft portion 44 is provided at the other end.

[0048] The tube holding portion 43 holds the corrugated tube 32. Here, the end portion of the corrugated tube 32 covers the tube holding portion 43. The tube holding portion 43 has an annular convex portion protruding toward the outer periphery of the cylindrical main body 42. By fitting the annular convex portion inside the large-diameter tube portion of the corrugated tube 32, the corrugated tube 32 is held by the tube holding portion 43.

[0049] 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 protrudes toward the outer periphery of the cylindrical main body 42 at the other end along the axial center direction of the cylindrical main body 42. The flange 45 protrudes more largely toward the outer periphery of the cylindrical main body 42 than the annular convex portion.

[0050] 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 corrugated tube 32.

[0051] 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 respectively located on both sides along the central axis CA direction 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 portion including the tube holding portion 43 in the shaft side protector 41 extends from the bearing portion 47 to the outside of the bearing side protector 46. An insertion through 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 through hole 50 corresponding to the wiring member 31 is formed at the center of the other of the pair of restricting wall portions 48.

[0052] The end 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 rotates around the central axis CA with the shaft side protector 41 integrally with respect to the bearing side protector 46. At this time, the bellows 32 may not rotate around the central axis CA with respect to the shaft side protector 41 at all, or may rotate slightly. The shaft side protector 41 is more likely to rotate with respect to the bearing side protector 46 than the bellows 32.

[0053] The circular shape of the bellows 32 may be deformed due to torque. Thus, when the bellows 32 is directly rotated around the central axis CA with respect to the bearing side protector 46 by torque, it may not rotate smoothly. Here, since the shaft side protector 41 attached to the bellows 32 rotates around the central axis CA with respect to the bearing side protector 46, it can rotate more smoothly than when the bellows 32 is directly rotated with respect to the bearing side protector 46.

[0054] The bearing side protector 46 supports the shaft side protector 41 so as to be substantially only rotatable around the central axis CA, so that it is possible to suppress the case where the space required for the movable body support member becomes large compared with the case of using a spherical portion. In addition, it may be that the shaft side protector 41 can rotate slightly with respect to the bearing side protector 46 in addition to rotating around the central axis CA due to the tolerance, clearance, etc. between the shaft portion 44 and the bearing portion 47.

[0055] The protection portion 51 is continuous with the bearing portion 47. The protection portion 51 covers the portion of the wire harness 30 extending 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 through hole 50 formed at the center of the other of the pair of restricting wall portions 48.

[0056] The wiring member 31 passes through the shaft side protector 41 and the bearing side protector 46. The wiring member 31 can also be inserted through the shaft side protector 41 and the bearing side protector 46 in a manner that allows it to float along the extending direction. Thus, the wiring member 31 is less likely to be affected by the external forces applied to the shaft side protector 41 and the bearing side protector 46.

[0057] 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 can be integrally formed using a mold, or the slider portion 54 formed independently of the protection wall portion 52 can be later installed on the protection wall portion 52.

[0058] 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 to keep the interval between the first slider portion 54A and the second slider portion 54B 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 protection wall portion 52. Therefore, the protection wall portion 52 can be regarded as the slider holding portion. The protection wall portion 52 as 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 protection 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 can also be bent and extended from the portion where the first slider portion 54A is provided to the portion where the second slider portion 54B is provided.

[0059] A guide groove 58 for guiding the slider portion 54 is formed in the guide member 56. The guide member 56 has a plate-shaped guide main body 57 that extends along the door panel 13. The guide groove 58 is formed in the guide main body 57. The slider portion 54 moves along the guide groove 58 in the guide member 56. The inner periphery 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.

[0060] 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 in the opening / closing groove 59 from the first end portion 60 toward the second end portion 61. The first end portion 60 is located at a position more forward of the vehicle than 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.

[0061] 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 from the first end portion 60 toward the front and downward of the vehicle. The stress absorption groove 62 is shorter than the opening / closing groove 59.

[0062] 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 that serves as the opening / closing groove 59 and a first stress absorption groove 62A that serves as the stress absorption groove 62. The second guide groove 58B has a second opening / closing groove 59B that serves as the opening / closing groove 59 and a second stress absorption groove 62B that serves as the stress absorption groove 62. The first guide groove 58A is located at a position higher than the second guide groove 58B.

[0063] 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 from the first end portion 60A toward the second end portion 61B to the rear and downward of the vehicle. The first opening / closing groove 59A is shorter than the second opening / closing groove 59B.

[0064] 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 constituted by 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.

[0065] The curved portion 59B1 extends in an arc shape centered on the first end portion 60A. Here, the curved portion 59Bl is shorter than a quarter arc (the arc of a quarter circle). The curved portion 59B1 may also be longer than a quarter arc. The straight portion 59B2 extends from the other end of the curved portion 59B1 in the tangential direction of the other end of the curved portion 59B1. The straight portion 59B2 is longer than the curved portion 59B1 and the first opening / closing groove 59A respectively. The extending direction of the straight portion 59B2 and the extending direction of the first opening / closing groove 59A are set to be in a mutually intersecting direction. The first opening / closing groove 59A is inclined more greatly with respect to the horizontal direction than the straight portion 59B2. The straight portion 59B2 extends linearly in parallel with the horizontal direction from the first end portion 60 toward the rear of the vehicle. 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 from the connecting portion of the curved portion 59B1 and the straight portion 59B2 toward the front of the vehicle with respect to the first end portion 60A. The straight portion 59B2 extends from the connecting portion of the curved portion 59B1 and the straight portion 59B2 toward the rear of the vehicle with respect to 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.

[0066] The first stress absorption groove 62A and the second stress absorption groove 62B are provided so as 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 toward the vehicle. The first stress absorption groove 62A and the second stress absorption groove 62B have the same length.

[0067] Since the first slider portion 54A and the second slider portion 54B are held at a constant interval by the protection wall portion 52, as Figure 7 shown, the first slider portion 54A and the second slider portion 54B interlock 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.

[0068] 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 portions of the bellows 32 supported by the shaft side protector 41 via the bearing side protector 46 extend along the extending direction of the bearing side protector 46.

[0069] The biasing portion 64 biases the slider portion 54 toward the opening / closing groove 59 along the extending direction of the stress absorbing groove 62. Here, the biasing portion 64 biases the slider portion 54 toward the first end portion 60 along the extending direction of the opening / closing groove 59. The biasing portion 64 biases the slider portion 54 in the direction between the extending direction of the opening / closing groove 59 and the extending direction of the stress absorbing groove 62. The biasing portion 64 may be, for example, a helical spring, a disc spring, or a constant load spring. A biasing portion support portion 65 that supports 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.

[0070] 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 extending direction of the first stress absorbing groove 62A, and is biased toward the first end portion 60 along the extending direction of the first opening / closing groove 59A.

[0071] 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 tube holding portion 71. The tube holding portion 71 supports the bellows 32 at a constant position along the extending direction. The tube holding portion 71 may support the bellows 32 so as to be rotatable about the central axis CA, or may support the bellows 32 so as not to be rotatable. The vehicle body support member 70 is attached to the vehicle body 10 at a constant position. As a result, 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 by the vehicle body 10 in a non-rotatable manner. As a result, 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 may be supported by the vehicle body 10 in a rotatable manner in order to be able to perform a nodding operation for changing the extending direction of the end portion of the bellows 32.

[0072] In each of one end portion and the other end portion of the bellows 32, a large-diameter cylinder portion and a small-diameter cylinder portion of a plurality of periodic quantities are respectively held by the tube holding portions 43 and 71. Accordingly, 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 tube holding portions 43 and 71.

[0073] 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 tube holding portion 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 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 side connector 37 and the tube holding portion 71.

[0074] 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. A 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 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.

[0075] <Regarding the operation of the slider portion and the deformation of the floating range>

[0076] The operation of the slider portion 54 and the deformation of the floating range 35 will be described in more detail.

[0077] When the state is changed 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 in 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 7In this case, when the second slider portion 54B moves in the linear portion 59B2 in the direction of arrow OC2B, the first slider portion 54A moves in the first opening / closing groove 59A in the direction of arrow OC1. At this time, since a rotational motion is also applied, the distance that the first slider portion 54A moves along the first opening / closing groove 59A is shorter than the distance that the second slider portion 54B moves along the linear portion 59B2.

[0078] In the first open state, most of the sliding door 12 is located at a position rearward of the vehicle compared to the boarding / 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.

[0079] In the closed state, the sliding door 12 closes the boarding / 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.

[0080] In the closed state, the first slider portion 54A and the second slider portion 54B are respectively located in the linear groove portions. 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 easily 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 also easily becomes 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 14 in the floating section 35 is difficult to be exposed to the vehicle interior space.

[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 Figure 7In the embodiment, when the second slider portion 54B moves in the second stress absorbing groove 62B along the direction of arrow SL2 , the first slider portion 54A moves in the first stress absorbing groove 62A along the direction of arrow SL1 .

[0082] For example, the exposed section 36 is located above a rigid component 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 can be set so that the exposed section 36 to which the pedal load F is applied can move to the rigid component. After the exposed section 36 to which the pedal load F is applied reaches the rigid component, the rigid component supports the exposed section 36 from below, so that the pedal load F is less likely to act as a tension of the wire harness 30. By having a rigid component, the exposed section 36 to which the pedal load F is applied is suppressed from moving downward from the step.

[0083] The length of the stress absorbing groove 62 may also be determined in consideration of the elongation and deformation of the bellows 32 attached to the exposed section 36. The length of the stress absorbing groove 62 may be shortened in accordance with the elongation and deformation of the bellows 32.

[0084] In the second open state, the first slider portion 54A and the second slider portion 54B are respectively located in the linear groove portion. Therefore, in the second open state, when the pedal load F is eliminated and the first slider portion 54A is forced toward the first end portion 60A, 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. Therefore, when the pedal load F is eliminated, the first slider portion 54A and the second slider portion 54B are easily returned to the first end portion 60A and the first end portion 60B by the force of the force applying portion 64.

[0085] The angle formed by the extending direction of the first stress absorbing groove 62A and the vertical direction is smaller than the angle formed by the extending direction of the first opening and closing groove 59A and the vertical direction. Therefore, the force applied by the force applying portion 64 when the first slider portion 54A moves the same distance from the first end portion 60 along the first stress absorbing groove 62A and the first opening and closing groove 59A is greater when the slider portion 54A moves in the first stress absorbing groove 62A.

[0086] The wiring member 31 is not fixed to the bellows 32 and the protectors 41 and 46, and can float along the extending direction relative to the bellows 32 and the protectors 41 and 46. When the above state changes, first, the bellows 32 and the protector 46 change their postures, and the wiring member 31 is pressed by the bellows 32 and the protectors 41 and 46 and changes its posture in a manner following the bellows 32 and the protectors 41 and 46. At this time, the portions of the bellows 32 and the protectors 41 and 46 that press the wiring member 31 change appropriately. Even in this case, since the wiring member 31 floats in the extending direction relative to the bellows 32 and the protectors 41 and 46, it is possible to prevent the tension of the portion of the wiring member 31 pressed by the bellows 32 and the protectors 41 and 46 from becoming excessive.

[0087] <Effects, etc.>

[0088] According to the door support member 40 configured as described above and the wiring structure 20 of the wire harness including the door support member 40, when a torque about the central axis CA is applied to the bellows 32, the bellows 32 receives this torque and rotates about the central axis CA relative to the bearing-side protector 46 via the shaft-side protector 41, thereby being able to absorb this torque. In addition, since the shaft portion 44 and the bearing portion 47 each have a cylindrical peripheral surface, compared with the case of being supported by a spherical member, the structure of the door support member 40 can be simplified, and the door support member 40 can be reduced in size. Further, since the torque applied to the bellows 32 is absorbed by the door support member 40, the structure of the vehicle body support member 70 can be simplified, and the size of the vehicle body support member 70 can also be reduced.

[0089] In addition, the bellows 32 covers the pipe holding portion 43 of the shaft-side protector 41. Thereby, the bellows 32 can be mounted on the outer periphery of the pipe holding portion 43.

[0090] In addition, the pipe holding portion 43 has a concavo-convex shape corresponding to the concavo-convex of the bellows 32, the shaft portion 44 has a flange 45 that protrudes radially along the central axis CA more than the pipe holding portion 43, and an annular recess 49 for fitting the flange 45 is formed in the bearing portion 47. Thereby, the shaft-side protector 41 and the bearing-side protector 46 can be made into a simple shape, and the shaft-side protector 41 can rotate smoothly relative to the bearing-side protector 46.

[0091] In addition, the bearing-side protector 46 has a protection portion 51 that is continuous with the bearing portion 47 on the side opposite to the floating section 35 along the extending direction of the wire harness 30 and covers the wire harness 30 (here, the door-side section 34). Thereby, the door-side section 34 of the wire harness 30 can be protected by the bearing-side protector 46.

[0092] In addition, the wiring member 31 is inserted through the bellows 32 in such a manner as to be able to float along the extending direction. Thus, when the bellows 32 and the shaft-side protector 41 rotate relative to the bearing-side protector 46 and the bellows 32 is twisted, it is difficult for the wiring member 31 inside the bellows 32 to be twisted.

[0093] In addition, the movable body is the sliding door 12. Therefore, it is possible to absorb the torque applied to the bellows 32 when the sliding door 12 is opened and closed.

[0094] In addition, the door support member 40 includes a guide member 56 formed with a guide groove 58, and the bearing-side protector 46 has a slider portion 54 which is supported by the guide member 56 in such a manner as to be able to slide along the guide groove 58 as the sliding door 12 is opened and closed. Thus, when the sliding door 12 is opened and closed, the portion of the bellows 32 attached to the shaft-side protector 41 slides along the guide groove 58 together with the bearing-side protector 46 and the shaft-side protector 41. In this way, even when the bellows 32 slides relative to the sliding door 12 together with the bearing-side protector 46 and the shaft-side protector 41 and torque is applied to the bellows 32, it is possible to absorb the torque applied to the bellows 32 when the sliding door 12 is opened and closed.

[0095] [Supplementary Note]

[0096] Figure 8 It is a diagram showing a modified example of the shaft-side protector 41 and the bearing-side protector 46.

[0097] The shaft-side protector 141 of the modified example is a member formed by combining a first divided member 141X and a 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 wiring harness 30 passes is divided along the axial direction. Similarly, the bearing-side protector 146 of the modified example is a member formed by combining a first divided member 146X and a 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 wiring harness 30 passes is divided along the axial direction. Thus, it becomes easier to mount the shaft-side protector 141 and the bearing-side protector 146 relative to the wiring harness 30 and the bellows 32. 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 other ratios.

[0098] In the divided 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 divided parts 146X and 146Y are aligned to form the above-mentioned restricting wall part 48 and the insertion through-hole 50. Here, the protection 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.

[0099] The fixing parts of the first divided parts 141X and 146X and the second divided parts 141Y and 146Y are fixed by threads or the like. The fixing parts of the first divided parts 141X and 146X and the second divided 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.

[0100] In addition, in this modification 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 divided 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 divided parts 141X and 141Y are aligned to form an annular convex part, which is fitted on the outside of the small-diameter cylindrical part.

[0101] In the bearing-side protector 146, the slider part 54 may not be divided and may be provided on either the first divided part 146X or the second divided part 146Y. The divided slider parts 54 may also be provided on the first divided part 146X and the second divided part 146Y respectively.

[0102] Figure 9 It is a schematic plan view showing a modification example of the wiring structure 20 of the wiring harness.

[0103] In the wiring structure 220 of the wiring harness of the modification example, the movable body is the seat 17 on which the occupant sits. The seat 17 has a frame 18A and a seat cushion 18B. The seat 17 is supported so as to be slidable relative to the slide rail 19 laid on the floor. The sliding direction of the seat 17 is usually the longitudinal direction of the vehicle, but it may also be other directions. The body supporting member 70 is supported on the floor. In the wiring structure 220 of the wiring harness, the wiring harness 230 connects the vehicle body side equipment and the seat side equipment. The wiring harness 230 has a seat side connector 238. The floating section 35 in the wiring harness 230 extends between the floor and the seat 17.

[0104] In this modification example, the support member for the movable body is the support member 240 for the seat. The support member 240 for the seat includes the shaft side protector 41 and the bearing side protector 246 in the same manner as the above-described support member 40 for the door. The bearing side protector 246 can also be configured, for example, to include a portion supported by the seat 17, instead of omitting the slider portion 54 from the above-described bearing side protector 46. The bearing side protector 246 can also be supported by the frame 18A of the seat 17, for example. In addition, the support member 240 for the seat does not include the guide member 56 and the biasing portion 64 in the above-described support member 40 for the door. The support member 240 for the seat can also include the guide member 56 and the biasing portion 64, etc.

[0105] When the seat 17 moves along the slide rail 19, the floating section 35 moves and changes its posture, and torque can be applied to the bellows 32. The bellows 32 rotates relative to the bearing side protector 246 about the central axis via the shaft side protector 41, thereby being able to absorb torque. Thus, the torque applied to the bellows 32 when the seat 17 slides can be absorbed.

[0106] In addition, heretofore, the case where the movable body side support member includes the shaft side protector and the bearing side protector has been described, but this is not an essential structure. The body support member can also be configured to include the shaft side protector and the bearing side protector. In this case, the movable body side support member can include the shaft side protector and the bearing side protector, or can not include the shaft side protector and the bearing side protector. That is, it can be configured such that only one of the body support member and the movable body side support member includes the shaft side protector and the bearing side protector, or it can be configured such that both the body support member and the movable body side support member include the shaft side protector and the bearing side protector.
