[0010] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described.

[0011] The wiring structure of the wire harness according to the present disclosure is as follows.

[0012] (1) A wiring structure for a wire harness that connects a device provided on a vehicle body and a device provided on a movable body that slides relative to the vehicle body, the wiring harness including a wiring member and a corrugated tube sheathed on the wiring member, the wire harness having a vehicle body side section supported on the vehicle body, a movable body side section supported on the movable body, and a floating section between the vehicle body side section and the movable body side section, a vehicle body support part that supports the corrugated tube in the vehicle body side section on the vehicle body, and a movable body that supports the corrugated tube in the movable body side section on the movable body. and a support part for a movable body, wherein at least one of the support part for the vehicle body and the support part for the movable body includes an axle side protector having an axle portion and a tube holding part, and a bearing side protector having a bearing portion, the tube holding part holds the corrugated tube so that their central axes coincide, the axle side protector is supported by the bearing side protector for rotation around the central axis via the bearing part and the axle portion, each of which has a cylindrical circumferential surface around the central axis, and the bearing side protector is supported by the vehicle body or the movable body.

[0013] According to the wiring structure of the wire harness in (1), when torque around the central axis is applied to the corrugated tube, the corrugated tube receives the torque and rotates around the central axis relative to the bearing-side protector via the shaft-side protector, thereby absorbing the torque. In addition, since the shaft and the bearing each have a cylindrical circumferential surface, the structure of the support parts can be simplified and the support parts can be made smaller than when supported by a spherical member.

[0014] (2) In the wiring harness arrangement structure of (1), the tube holding portion may cover the corrugated tube, whereby the tube holding portion can be attached to an outer periphery of the corrugated tube.

[0015] (3) In the wiring harness arrangement structure of (1), the corrugated tube may cover the tube holding portion, whereby the corrugated tube can be attached to an outer periphery of the tube holding portion.

[0016] (4) In the wiring structure of any one of (1) to (3), the tube holding portion may have an uneven shape corresponding to the unevenness of the corrugated tube, the shaft portion may have a flange that protrudes radially from the central shaft beyond the tube holding portion, and the bearing portion may have an annular recess into which the flange fits. This allows the shaft side protector and the bearing side protector to have simple shapes, while allowing the shaft side protector to rotate smoothly relative to the bearing side protector.

[0017] (5) In the wiring structure of any one of (1) to (4), the bearing-side protector may have a protective portion that is continuous with the bearing portion on the opposite side to the free section along the extension direction of the wire harness and covers the wire harness. This makes it possible to protect the wire harness by the bearing-side protector.

[0018] (6) In any one of the wiring harness arrangement structures (1) to (5), the shaft side protector and the bearing side protector may each be a component formed by combining a first divided component and a second divided component having a shape divided along the axial direction. This makes it easy to later attach the shaft side protector and the bearing side protector to the wire harness and the corrugated tube.

[0019] (7) In the wiring harness arrangement structure of any one of (1) to (6), the wiring member may be inserted through the corrugated tube in a freely movable manner along an extension direction of the wiring member, so that when the corrugated tube and the shaft side protector rotate relative to the bearing side protector and the corrugated tube twists, the wiring member inside the corrugated tube is less likely to twist.

[0020] (8) In the wiring harness arrangement structure of any one of (1) to (7), the movable body may be a sliding door, whereby torque applied to the corrugated tube when the sliding door is opened or closed can be absorbed by the shaft side protector and the bearing side protector.

[0021] In the wiring structure of the wire harness of (9) and (8), the movable body support part may include the shaft side protector, the bearing side protector, and a guide part having a guide groove formed therein, and the bearing side protector may have a slider part supported by the guide part so as to be slidable along the guide groove as the sliding door is opened and closed. In this way, when the sliding door is opened and closed, the part of the corrugated tube attached to the shaft side protector slides along the guide groove together with the bearing side protector and the shaft side protector. In this way, even if torque is applied to the corrugated tube while the corrugated tube slides relative to the sliding door together with the bearing side protector and the shaft side protector, the torque applied to the corrugated tube when the sliding door is opened and closed can be absorbed.

[0022] (10) In the wiring harness arrangement structure of any one of (1) to (7), the movable body may be a seat. In this way, torque applied to the corrugated tube when the seat slides can be absorbed by the shaft side protector and the bearing side protector.

[0023] (11) Furthermore, a support part of the present disclosure includes a wiring member and a corrugated tube sheathed on the wiring member, and is a support part that supports the vehicle body side section or the movable body side section of a wire harness, the wire harness having a vehicle body side section supported on a vehicle body, a movable body side section supported on a movable body that slides relative to the vehicle body, and a free section between the vehicle body side section and the movable body side section, on the vehicle body or the movable body, and includes an axle side protector including an axle portion and a tube holding portion, and a bearing side protector including a bearing portion, wherein the tube holding portion holds the corrugated tube so that their central axes coincide, and the axle side protector is supported by the bearing side protector rotatably around the central axis via the bearing portion and the axle portion, each of which has a cylindrical circumferential surface around the central axis, and the bearing side protector is supported by the vehicle body or the movable body.

[0024] According to the support part of (11), when torque around the central axis is applied to the corrugated tube, the corrugated tube receives the torque and rotates around the central axis relative to the bearing-side protector via the shaft-side protector, thereby absorbing the torque. In addition, since the shaft portion and the bearing portion each have a cylindrical circumferential surface, the structure of the support part can be simplified and the support part can be made smaller than when supported by a spherical member.

[0025] [Details of the embodiment of the present disclosure] Specific examples of the wiring structure of the wire harness of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0026] [Embodiment 1] The wiring structure of the wire harness according to the first embodiment will be described below. In this embodiment, FIG. 1 will be used as an example in which the movable body is a sliding door. FIG. 1 is a schematic plan view showing a wiring structure 20 of the wire harness. The front-rear direction (FRONT, REAR) and the up-down direction (UP, LOW) shown in FIG. 1 correspond to the front-rear direction and the up-down direction in the vehicle. The inside-outside direction (IN, OUT) shown in FIG. 1 corresponds to the inside-outside direction with respect to the side of the vehicle among the left-right directions in the vehicle. Specifically, FIG. 1 shows the right side of the vehicle, and the side to the left of the right side of the vehicle is the inside of the vehicle, and the side to the right of the right side of the vehicle is the outside of the vehicle.

[0027] First, a relationship between the wiring structure 20 of the wire harness and the vehicle body 10 and the sliding door 12 to which the wiring structure 20 is applied will be described. In Fig. 1, the wiring structure 20 of the wire harness shown by a solid line indicates a state in which the sliding door 12 is open, and the wiring structure 20 of the wire harness shown by a two-dot chain line indicates a state in which the sliding door 12 is closed. In Fig. 1, some members such as the sliding door 12 are shown by two-dot chain lines in both the open and closed states.

[0028] A vehicle body 10 is provided with an opening 11 for passengers to get on and off the vehicle at a side thereof. A sliding door 12 is slidably supported by the vehicle body 10. The opening 11 for passengers to get on and off is opened and closed by the sliding door 12 sliding. The sliding door 12 includes a door panel 13 that defines the appearance of the sliding door 12, and a door trim 14 that is provided on the vehicle interior side of the door panel 13. For example, a support arm 15 that supports the sliding door 12 is slidably supported by a support rail that is disposed on the vehicle body 10. A weather strip 16 is disposed around the periphery of the opening 11 for passengers to get on and off so as to come into contact with the door panel 13 and the vehicle body 10. For example, the weather strip 16 is disposed in a ring shape on the outer periphery side of the door trim 14 when the sliding door 12 is closed.

[0029] The sliding door 12 is provided with door-side devices such as a power window. The door-side devices are connected to vehicle-body-side devices (such as an ECU) provided in the vehicle body 10 via a wire harness 30. The wire harness 30 is routed across the vehicle body 10 and the sliding door 12. The wiring structure 20 for the wire harness includes the wire harness 30 that connects the vehicle-body-side devices and the door-side devices, a door support part 40 that supports the wire harness 30 on the sliding door 12, and a vehicle-body support part 70 that supports the wire harness 30 on the vehicle body 10.

[0030] The wire harness 30 includes a wiring member 31 that transmits power or signals between a door-side device and a vehicle-body-side device, and a corrugated tube 32 that is sheathed by the wiring member 31. The wiring member 31 is, for example, an electric wire or an optical fiber cable. The wiring member 31 may be one or more. The corrugated tube 32 protects the wiring member 31 and bundles the multiple wiring members 31 together. The corrugated tube 32 has a shape in which large-diameter cylindrical portions and small-diameter cylindrical portions, each of which has a circular cross section, are alternately connected. The outer and inner surfaces of the corrugated tube 32 have a continuous uneven shape corresponding to the large-diameter cylindrical portions and the small-diameter cylindrical portions along the extension direction. In FIG. 1, the end portion of the corrugated tube 32 is depicted in a shape that conforms to the original shape of the corrugated tube 32 having an uneven shape, but the middle portion of the corrugated tube 32 is depicted in a simplified shape that omits the uneven shape. The same is true in FIG. 2 and the subsequent figures.

[0031] The wire harness 30 includes a vehicle body side section 33 supported by the vehicle body 10, a door side section 34 supported by the door, and a free section 35 between the vehicle body side section 33 and the door side section 34. The vehicle body side section 33, the door side section 34, and the free section 35 are different sections from each other along the extension direction of the wire harness 30.

[0032] The vehicle body side section 33 is supported on the vehicle body 10 by a vehicle body support part 70. The vehicle body side section 33 is held on the vehicle body 10 when the sliding door 12 is opened or closed. The vehicle body side section 33 is disposed, for example, above a floor panel, and is covered by a floor carpet or a floor mat to prevent it from being exposed. For example, the vehicle body 10 is provided with a vehicle body side harness opening for leading out the wire harness 30 around the entry / exit opening 11. The vehicle body support part 70 shown in FIG. 1 supports a portion of the vehicle body side section 33 that is connected to the free section 35 around the vehicle body side harness opening. The free section 35 extends to the outside of the vehicle body 10 through the vehicle body side harness opening.

[0033] The door side section 34 is a section supported by the sliding door 12 by a door support part 40. When the sliding door 12 is opened or closed, the door side section 34 is held by the sliding door 12 and moves together with the sliding door 12 relative to the vehicle body 10. Here, when the sliding door 12 is opened or closed, a part of the door side section 34 is supported by the door support part 40 so as to move along a fixed path relative to the sliding door 12. The door side section 34 is disposed between the door panel 13 and the door trim 14, so that exposure is suppressed. The door trim 14 is provided with a door side harness opening through which the wire harness 30 is led out. The door side harness opening is provided, for example, in a lower part of the door trim 14. The floating section 35 extends to the outside of the sliding door 12 through the door side harness opening.

[0034] The free-floating section 35 is not supported by the vehicle body 10 and the sliding door 12, and can move freely relative to the vehicle body 10 and the sliding door 12, as compared with the vehicle body side section 33 and the door side section 34. When the sliding door 12 is opened or closed, the free-floating section 35 is pulled by the sliding door 12, and moves and changes its position relative to the vehicle body 10 and the sliding door 12. The corrugated tube 32 is provided in the free-floating section 35. Here, it is assumed that the free-floating section 35 moves three-dimensionally when the sliding door 12 is opened or closed, and the corrugated tube 32 can follow the three-dimensional movement of the free-floating section 35. One end of the corrugated tube 32 extends to the vehicle body side section 33 and is supported by the vehicle body 10 by a vehicle body support part 70. The other end of the corrugated tube 32 extends to the door side section 34 and is supported by the sliding door 12 by a door support part 40.

[0035] The free movement section 35 has an exposed section 36. The exposed section 36 is a section that is exposed between the vehicle body 10 and the sliding door 12 when the sliding door 12 is open. Here, the corrugated tube 32 provided in the free movement section 35 is exposed. For example, the exposed section 36 is a portion of the free movement section 35 between the vehicle body side harness opening and the door side harness opening.

[0036] The exposed section 36 is exposed at a position that is least likely to interfere with passengers getting on and off, such as a position at the rear and lower part of the boarding / alighting opening 11. However, since the exposed section 36 is exposed to the boarding / alighting opening 11, it is difficult to completely prevent the exposed section 36 from being stepped on by passengers getting on and off through the boarding / alighting opening 11. In addition, since the corrugated tube 32 provided in the free section 35 is easily bent and deformed, it is difficult for the corrugated tube 32 alone to support a stepped-on load. Here, the tension applied to the exposed section 36 is prevented from increasing when a stepped-on load is applied to the exposed section 36.

[0037] In the following, a state in which the sliding door 12 is closed is referred to as a closed state. A state in which the sliding door 12 is open and no load is applied to the exposed section 36 is referred to as a first open state. The first open state is a state in which the free section 35 is in a natural state. A state in which the sliding door 12 is open and a load F is applied to the exposed section 36 is referred to as a second open state.

[0038] Each part of the wiring harness wiring structure 20 will be described in more detail. Fig. 2 is a schematic perspective view showing the wiring harness wiring structure 20. Fig. 3 is a schematic front view showing a first open state. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3. Fig. 5 is a schematic front view showing a closed state. Fig. 6 is a schematic front view showing a second open state. Fig. 7 is an explanatory diagram showing the trajectory of the slider portion 54.

[0039] In the wire harness 30, the wiring member 31 is inserted through the corrugated tube 32 in a freely movable manner along the extending direction. This makes the wiring member 31 less susceptible to the effect of an external force applied to the corrugated tube 32. Specifically, the wiring member 31 simply passes through the inside of the corrugated tube 32 and is not fixed to the corrugated tube 32. Therefore, even if the corrugated tube 32 is twisted, the wire harness 30 is less likely to be twisted. In addition, when the middle part of the corrugated tube 32 is pressed in a direction intersecting the axial direction, the corrugated tube 32 bends as if pulled in the pushed direction while reducing the difference in the concave and convex parts, and can be stretched and deformed to become longer. At this time, when the wiring member 31 is pressed by the corrugated tube 32, the wiring member 31 moves freely along the extending direction, and the tension applied to the wiring member 31 is prevented from increasing.

[0040] The door support component 40 includes a shaft side protector 41, a bearing side protector 46, a guide component 56, and a biasing portion 64.

[0041] The shaft side protector 41 includes a tubular main body 42, a tube holding portion 43, and a shaft portion 44. The shaft side protector 41 is made of resin or metal. The rigidity of the shaft side protector 41 is higher than the rigidity of the corrugated tube 32. The tubular main body 42 is formed in a cylindrical shape. The tube holding portion 43 is provided at one end along the axial direction of the tubular main body 42, and the shaft portion 44 is provided at the other end.

[0042] The tube holding portion 43 holds the corrugated tube 32. Here, an end of the corrugated tube 32 covers the tube holding portion 43. The tube holding portion 43 has an annular protrusion that protrudes from the outer periphery of the cylindrical main body 42. The corrugated tube 32 is held by the tube holding portion 43 as the annular protrusion fits inside the large diameter cylindrical portion of the corrugated tube 32.

[0043] The shaft portion 44 is a portion that is supported by the bearing-side protector 46. The shaft portion 44 has a flange 45. The flange 45 protrudes onto the outer periphery of the cylindrical main body 42 at the other end along the axial direction of the cylindrical main body 42. The flange 45 protrudes onto the outer periphery of the cylindrical main body 42 more than the annular protrusion.

[0044] The bearing side protector 46 includes a bearing portion 47, a protective portion 51, and a slider portion 54. The bearing side protector 46 is made of resin or metal. The rigidity of the bearing side protector 46 is higher than the rigidity of the corrugated tube 32.

[0045] The bearing portion 47 supports the shaft portion 44 so that it can rotate. The bearing portion 47 and the shaft portion 44 each have a cylindrical circumferential surface around the central axis CA. Here, the shaft portion 44 has a cylindrical outer circumferential surface, and the bearing portion 47 has a cylindrical inner circumferential surface. Here, the bearing portion 47 has a pair of restricting wall portions 48. The pair of restricting wall portions 48 are located on both sides of the flange 45 along the central axis CA direction. Between the pair of restricting wall portions 48 is an annular recess 49 into which the flange 45 fits. A portion of the shaft side protector 41 including the tube holding portion 43 extends from the bearing portion 47 to the outside of the bearing side protector 46. An insertion hole 50 corresponding to the cylindrical main body 42 is formed in the center of one of the pair of restricting wall portions 48. An insertion hole 50 corresponding to the wiring member 31 is formed in the center of the other of the pair of restricting wall portions 48.

[0046] An end of the corrugated tube 32 is supported by the bearing-side protector 46 via the shaft-side protector 41 so as to be rotatable about the central axis CA. The corrugated tube 32 rotates integrally with the shaft-side protector 41 about the central axis CA relative to the bearing-side protector 46. At this time, the corrugated tube 32 may not rotate at all about the central axis CA relative to the shaft-side protector 41, or may rotate slightly. The shaft-side protector 41 rotates more easily relative to the bearing-side protector 46 than the corrugated tube 32.

[0047] The corrugated tube 32 may lose its circular shape due to torque. As a result, when the corrugated tube 32 is directly rotated around the central axis CA relative to the bearing-side protector 46 by torque, it may not rotate smoothly. Here, the shaft-side protector 41 attached to the corrugated tube 32 rotates around the central axis CA relative to the bearing-side protector 46, so the corrugated tube 32 can rotate more smoothly than when it is directly rotated relative to the bearing-side protector 46.

[0048] Since the bearing-side protector 46 supports the shaft-side protector 41 so as to be rotatable substantially only about the central axis CA, the space required for the movable body support component is prevented from increasing compared to the case where a spherical portion is used. Note that, depending on the tolerance and play between the shaft portion 44 and the bearing portion 47, the shaft-side protector 41 may be able to rotate somewhat relative to the bearing-side protector 46 in a direction other than the central axis CA.

[0049] The protective portion 51 is continuous with the bearing portion 47. The protective portion 51 covers a portion of the wire harness 30 extending from the bearing portion 47. The protective portion 51 has a protective wall portion 52 that covers at least a portion of the wire harness 30 along the circumferential direction. Here, the protective portion 51 is formed in a tubular shape so that the protective wall portion 52 covers the entire circumference of the wire harness 30. The protective portion 51 may be cylindrical or may be rectangular. The protective wall portion 52 extends from the periphery of an insertion hole 50 formed in the center of the other of the pair of regulating wall portions 48.

[0050] The wiring member 31 passes through the shaft side protector 41 and the bearing side protector 46. The wiring member 31 may be inserted through the shaft side protector 41 and the bearing side protector 46 in a manner allowing it to move freely along the extension direction. This makes the wiring member 31 less susceptible to the effects of external forces acting on the shaft side protector 41 and the bearing side protector 46.

[0051] The slider portion 54 is provided in the door-side section 34. The slider portion 54 protrudes from the outer surface of the protective wall portion 52. The slider portion 54 has a columnar portion that protrudes in a columnar shape from the outer surface of the protective wall portion 52. A circumferential groove is formed on the outer surface of the columnar portion. The slider portion 54 and the protective wall portion 52 may be integrally molded using a mold, or the slider portion 54, which is molded separately from the protective wall portion 52, may be attached to the protective wall portion 52 later.

[0052] The slider portion 54 includes a first slider portion 54A and a second slider portion 54B. The first slider portion 54A and the second slider portion 54B are connected by a slider holding portion so as to keep the distance between the first slider portion 54A and the second slider portion 54B constant. Here, the slider holding portion can be regarded as a slider holding portion. The first slider portion 54A and the second slider portion 54B are provided at positions spaced apart from each other along the extension direction of the door side section 34 on the outer surface of the protective wall portion 52. Therefore, the protective wall portion 52 can be regarded as a slider holding portion. The protective wall portion 52 as a slider holding portion covers and protects the door side section 34 from the portion where the first slider portion 54A is provided to the portion where the second slider portion 54B is provided. The protective wall portion 52 extends linearly between the portion where the first slider portion 54A is provided and the portion where the second slider portion 54B is provided. The protective portion 51 may bend and extend from the portion where the first slider portion 54A is provided to the portion where the second slider portion 54B is provided.

[0053] The guide part 56 has a guide groove 58 that guides the slider part 54. The guide part 56 has a plate-shaped guide body 57 that extends along the door panel 13. The guide groove 58 is formed in the guide body 57. The slider part 54 moves along the guide groove 58 in the guide part 56. The inner peripheral edge of the guide groove 58 fits into the circumferential groove of the slider part 54. The guide groove 58 has an opening / closing groove 59 and a stress absorbing groove 62.

[0054] The opening / closing groove 59 has a first end 60 and a second end 61. The slider portion 54 is located at the first end 60 of the opening / closing groove 59 in the first open state. The opening / closing groove 59 is provided such that the slider portion 54 moves in the opening / closing groove 59 from the first end 60 toward the second end 61 when changing from the first open state to the closed state. The first end 60 is located further forward of the vehicle than the second end 61. In the open state, the second end 61 is located farther from the vehicle body support component 70 than the first end 60. In the closed state, the first end 60 is located farther from the vehicle body support component 70 than the second end 61. In the opening / closing groove 59, the second end 61 is located lower in the vertical direction than the first end 60.

[0055] The stress absorption groove 62 extends from the first end 60 in a direction intersecting the extension direction of the opening / closing groove 59. The stress absorption groove 62 is provided so that the slider portion 54 moves along the stress absorption groove 62 when changing from the first open state to the second open state. The stress absorption groove 62 has an end opposite to the first end 60 at a lower position in the vertical direction than the first end 60. The stress absorption groove 62 extends from the first end 60 forward and downward of the vehicle. The stress absorption groove 62 is shorter than the opening / closing groove 59.

[0056] The guide groove 58 has a first guide groove 58A that guides the first slider portion 54A and a second guide groove 58B that guides the second slider portion 54B. The first guide groove 58A has a first opening / closing groove 59A as the opening / closing groove 59 and a first stress absorption groove 62A as the stress absorption groove 62. The second guide groove 58B has a second opening / closing groove 59B as the opening / closing groove 59 and a second stress absorption groove 62B as the stress absorption groove 62. The first guide groove 58A is located above the second guide groove 58B.

[0057] The first opening / closing groove 59A has a first end 60A and a second end 61A. Here, the first opening / closing groove 59A is composed of only a straight portion. The first opening / closing groove 59A extends linearly from the first end 60A to the second end 61B toward the rear and downward of the vehicle. The first opening / closing groove 59A is shorter than the second opening / closing groove 59B.

[0058] The second opening / closing groove 59B has a first end 60B and a second end 61B. The second opening / closing groove 59B includes a curved portion 59B1. The second opening / closing groove 59B is configured by a combination of the curved portion 59B1 and a straight portion 59B2. In the second opening / closing groove 59B, the first end 60B side is the curved portion 59B1, and the second end 61B side is the straight portion 59B2. One end of the curved portion 59B1 is the first end 60B, one end of the straight portion 59B2 is the second end 61B, and the other end of the curved portion 59B1 and the other end of the straight portion 59B2 are continuous.

[0059] The curved portion 59B1 extends in an arc shape centered on the first end 60A. Here, the curved portion 59B1 is shorter than a quarter-circular arc (a quadrant of a circular arc). The curved portion 59B1 may be longer than a quarter-circular arc. The straight portion 59B2 extends from the other end of the curved portion 59B1 in a tangential direction at the other end of the curved portion 59B1. The straight portion 59B2 is longer than both the curved portion 59B1 and the first opening / closing groove 59A. The extending direction of the straight portion 59B2 and the extending direction of the first opening / closing groove 59A intersect with each other. The first opening / closing groove 59A is inclined more to the horizontal direction than the straight portion 59B2. The straight portion 59B2 extends linearly from the first end 60 toward the rear of the vehicle in parallel with the horizontal direction. The connecting portion between the curved portion 59B1 and the straight portion 59B2 is located directly below the first end 60A. The curved portion 59B1 extends from the connecting portion between the curved portion 59B1 and the straight portion 59B2 toward the front of the vehicle beyond the first end portion 60A. The straight portion 59B2 extends from the connecting portion between the curved portion 59B1 and the straight portion 59B2 toward the rear of the vehicle beyond the first end portion 60A. The first end portion 60B is located further forward of the vehicle than the first end portion 60A, and the second end portion 61B is located further rearward of the vehicle than the first end portion 60A.

[0060] The first stress absorption groove 62A and the second stress absorption groove 62B are provided to extend along a straight line. The second stress absorption groove 62B is located on a virtual extension line of the first stress absorption groove 62A extending downwardly of the vehicle. The first stress absorption groove 62A and the second stress absorption groove 62B have the same length.

[0061] Since the first slider portion 54A and the second slider portion 54B are held at a constant distance by the protective wall portion 52, as shown in FIG. 7, the first slider portion 54A and the second slider portion 54B move in conjunction with each other while maintaining a constant distance. The distance is the distance between the first end portion 60A and the first end portion 60B. In the first open state, the first slider portion 54A is located at the first end portion 60A, and the second slider portion 54B is located at the first end portion 60B. The distance between the second end portion 61A and the second end portion 61B is also the same as the distance between the first end portion 60A and the first end portion 60B.

[0062] The position of the bearing side protector 46 is determined by the positions of the first slider portion 54A and the second slider portion 54B, and the position of the bearing side protector 46 determines the positions of the shaft side protector 41 and the end of the corrugated tube 32. The bearing side protector 46 extends in a direction connecting the positions of the first slider portion 54A and the second slider portion 54B. The end of the corrugated tube 32 supported by the bearing side protector 46 via the shaft side protector 41 extends in the extension direction of the bearing side protector 46.

[0063] The biasing portion 64 biases the slider portion 54 toward the opening / closing groove 59 along the extension direction of the stress absorption groove 62. Here, the biasing portion 64 biases the slider portion 54 toward the first end portion 60 along the extension direction of the opening / closing groove 59. The biasing portion 64 biases the slider portion 54 in a direction between the extension direction of the opening / closing groove 59 and the extension direction of the stress absorption groove 62. The biasing portion 64 may be, for example, a spring such as a coil spring, a power spring, or a constant load spring. The slider portion 54 is provided with a biasing portion support portion 65 that supports one end of the biasing portion 64. The other end of the biasing portion 64 is supported by, for example, the guide body 57 or the like.

[0064] Here, the biasing portion 64 is connected to the first slider portion 54A. The biasing portion 64 biases the first slider portion 54A upward in the vertical direction. As a result, the first slider portion 54A is biased toward the first opening / closing groove 59A along the extension direction of the first stress absorption groove 62A, and is also biased toward the first end portion 60 along the extension direction of the first opening / closing groove 59A.

[0065] The vehicle body support part 70 supports the vehicle body side section 33 to the vehicle body 10 at a position of the vehicle body side section 33 adjacent to the free moving section 35. The vehicle body support part 70 has a tube holding part 71. The tube holding part 71 supports the corrugated tube 32 at a fixed position along the extension direction. The tube holding part 71 may support the corrugated tube 32 rotatably about the central axis CA, or may support the corrugated tube 32 non-rotatably. The vehicle body support part 70 is attached to the vehicle body 10 at a fixed position. As a result, the vehicle body 10 side end of the corrugated tube 32 is held at a fixed position on the vehicle body 10. The vehicle body support part 70 is supported non-rotatably on the vehicle body 10. As a result, the direction in which the vehicle body 10 side end of the corrugated tube 32 extends from the vehicle body support part 70 is held in a fixed direction. The vehicle body support component 70 may be rotatably supported on the vehicle body 10 to allow a pivoting movement for changing the direction in which the end of the corrugated tube 32 extends.

[0066] At each of one end and the other end of the corrugated tube 32, several periods of large diameter cylindrical portions and small diameter cylindrical portions are held by the tube holding portions 43, 71. Therefore, at each of one end and the other end of the corrugated tube 32, bending of the corrugated tube 32 is restricted by the tube holding portions 43, 71.

[0067] The vehicle body connector 37 at one end of the wiring member 31 is connected to a vehicle body device, thereby positioning and fixing the wiring member 31 to the vehicle body 10. The tube holding portion 71 of the vehicle body support part 70 positions and fixes the corrugated tube 32 along the extension direction. Since the wiring member 31 is not fixed to the corrugated tube 32, it is not positioned and fixed to the tube holding portion 71. A fixing portion for positioning and fixing the wiring member 31 to the vehicle body 10 may also be provided between the vehicle body connector 37 and the tube holding portion 71.

[0068] The door-side connector 38 at the other end of the wiring member 31 is connected to a door-side device, and thereby positioned and fixed to the sliding door 12. The portion of the wiring member 31 passing through the shaft-side protector 41 and the bearing-side protector 46 is movable relative to the protectors 41, 46 and moves relative to the sliding door 12, and is not positioned and fixed to the sliding door 12. A fixing portion for positioning and fixing the wiring member 31 to the sliding door 12 may also be provided between the door-side connector 38 and the bearing-side protector 46.

[0069] <Slider operation and deformation of the free-floating section> The operation of the slider portion 54 and the deformation of the free movement section 35 will now be described in more detail.

[0070] When the sliding door 12 is opened or closed, the first slider portion 54A moves along the first opening / closing groove 59A, and the second slider portion 54B moves along the second opening / closing groove 59B. When the second slider portion 54B moves along the curved portion 59B1 from the first end portion 60B to the second end portion 61B, the first slider portion 54A remains at the first end portion 60A until the second slider portion 54B reaches the straight portion 59B2. When the second slider portion 54B moves along the straight portion 59B2, the first slider portion 54A moves along the first opening / closing groove 59A. More specifically, in FIG. 7, when the second slider portion 54B moves along the curved portion 59B1 along the direction of the arrow OC2A, the first slider portion 54A rotates while remaining at the first end portion 60A. 7, when the second slider portion 54B moves on the straight portion 59B2 in the direction of the arrow OC2B, the first slider portion 54A moves on the first opening / closing groove 59A in the direction of the arrow OC1. At this time, due to the addition of a rotational motion, the distance that the first slider portion 54A moves on the first opening / closing groove 59A becomes shorter than the distance that the second slider portion 54B moves on the straight portion 59B2.

[0071] In the first open state, most of the sliding door 12 is located rearward of the entrance / exit opening 11, and therefore the shaft side protector 41 is located rearward of the vehicle body support component 70. At this time, the bearing side protector 46 extends in a direction connecting the first end 60A and the first end 60B, and the corrugated tube 32 extends from the shaft side protector 41 toward the front and downward of the vehicle.

[0072] In the closed state, the sliding door 12 closes the entrance / exit opening 11, and therefore the shaft-side protector 41 is located further forward in the vehicle than the vehicle body support component 70. At this time, the bearing-side protector 46 extends in a direction connecting the first slider portion 54A located near the second end 61A and the second slider portion 54B located near the second end 61B, and the corrugated tube 32 extends from the shaft-side protector 41 toward the rear and downward of the vehicle.

[0073] In the closed state, the first slider portion 54A and the second slider portion 54B are located in the linear grooves. As a result, when the first slider portion 54A is biased toward the first end portion 60A in the closed state, the first slider portion 54A and the second slider portion 54B are easily moved toward the first end portion 60A and the first end portion 60B. Here, sagging may occur in the free movement section 35 in the closed state. Even in this case, the first slider portion 54A and the second slider portion 54B move toward the first end portion 60A and the first end portion 60B, so that the free movement section 35 is easily put in a state where a moderate tension is applied, and sagging is unlikely to occur in the free movement section 35. As a result, the portion of the free movement section 35 that extends outside the door trim 14 in the closed state is unlikely to be exposed to the interior space of the vehicle.

[0074] When a stepping load F is applied to the exposed section 36 or the stepping load F is removed, and the state is changed between the first open state and the second open state, the first slider portion 54A moves along the first stress absorption groove 62A, and the second slider portion 54B moves along the second stress absorption groove 62B. The distance that the first slider portion 54A moves along the first stress absorption groove 62A is the same as the distance that the second slider portion 54B moves along the second stress absorption groove 62B. More specifically, in FIG. 7, when the second slider portion 54B moves along the second stress absorption groove 62B along the direction of the arrow SL2, the first slider portion 54A moves along the first stress absorption groove 62A along the direction of the arrow SL1.

[0075] For example, the exposed section 36 is located above a rigid part of the vehicle (such as the support arm 15 or a step portion of the vehicle). For example, the length of the stress absorbing groove 62 may be set so that the exposed section 36, to which the stepped load F is applied, can move up to the rigid part. After the exposed section 36, to which the stepped load F is applied, reaches the rigid part, the rigid part supports the exposed section 36 from below, making it difficult for the stepped load F to act as tension on the wire harness 30. The presence of the rigid part prevents the exposed section 36, to which the stepped load F is applied, from moving below the step.

[0076] The length of the stress absorbing groove 62 may take into consideration the elongation deformation of the corrugated tube 32 that is fitted to the exposed section 36. The length of the stress absorbing groove 62 can be shortened by the amount of the elongation deformation of the corrugated tube 32.

[0077] In the second open state, the first slider portion 54A and the second slider portion 54B are located in the linear grooves. As a result, in the second open state, when the stepping load F is released and the first slider portion 54A is urged toward the first end 60A, the first slider portion 54A and the second slider portion 54B are likely to move toward the first end 60A and the first end 60B. Therefore, when the stepping load F is released, the first slider portion 54A and the second slider portion 54B are likely to return to the first end 60A and the first end 60B by the urging force of the urging portion 64.

[0078] The angle between the extension direction of the first stress absorption groove 62A and the vertical direction is smaller than the angle between the extension direction of the first opening / closing groove 59A and the vertical direction. Therefore, when the first slider portion 54A moves the same distance from the first end portion 60 along the first stress absorption groove 62A and the first opening / closing groove 59A, the biasing force of the biasing portion 64 is larger when the first slider portion 54A moves along the first stress absorption groove 62A.

[0079] The wiring member 31 is not fixed to the corrugated tube 32 and the protectors 41, 46, and is movable relative to the corrugated tube 32 and the protectors 41, 46 in the extension direction. When the state is changed, the corrugated tube 32 and the protectors 41, 46 first change their posture, and the wiring member 31 is pushed by the corrugated tube 32 and the protectors 41, 46 and changes its posture to follow the corrugated tube 32 and the protectors 41, 46. At this time, the portion of the wiring member 31 that is pushed by the corrugated tube 32 and the protectors 41, 46 changes as appropriate. Even in this case, the wiring member 31 moves relative to the corrugated tube 32 and the protectors 41, 46 in the extension direction, thereby preventing the tension in the portion of the wiring member 31 that is pushed by the corrugated tube 32 and the protectors 41, 46 from becoming too large.

[0080] <Effects, etc.> According to the door support part 40 and the wiring structure 20 of the wire harness including the door support part 40 configured as described above, when a torque about the central axis CA is applied to the corrugated tube 32, the corrugated tube 32 receives the torque and rotates about the central axis CA relative to the bearing-side protector 46 via the shaft-side protector 41, thereby absorbing the torque. Since the shaft portion 44 and the bearing portion 47 each have a cylindrical peripheral surface, the structure of the door support part 40 can be simplified and the door support part 40 can be made smaller than when supported by a spherical member. Furthermore, since the torque applied to the corrugated tube 32 is absorbed by the door support part 40, the structure of the vehicle body support part 70 can be simplified and the vehicle body support part 70 can be made smaller.

[0081] In addition, the corrugated tube 32 covers the tube holding portion 43 of the shaft side protector 41. This allows the corrugated tube 32 to be attached to the outer periphery of the tube holding portion 43.

[0082] Furthermore, the tube holding portion 43 has an uneven shape corresponding to the unevenness of the corrugated tube 32, the shaft portion 44 has a flange 45 that protrudes radially from the tube holding portion 43 along the central axis CA, and the bearing portion 47 is formed with an annular recess 49 into which the flange 45 fits. This allows the shaft side protector 41 to rotate smoothly relative to the bearing side protector 46 while maintaining a simple shape for the shaft side protector 41 and the bearing side protector 46.

[0083] The bearing-side protector 46 has a protective portion 51 that is continuous with the bearing portion 47 on the opposite side to the free section 35 along the extending direction of the wire harness 30 and covers the wire harness 30 (here, the door-side section 34). This allows the bearing-side protector 46 to protect the door-side section 34 of the wire harness 30.

[0084] Moreover, the wiring member 31 is inserted through the corrugated tube 32 so as to be freely movable along the extending direction thereof. As a result, when the corrugated tube 32 and the shaft-side protector 41 rotate relative to the bearing-side protector 46 and the corrugated tube 32 twists, the wiring member 31 inside the corrugated tube 32 is less likely to twist.

[0085] In addition, the movable body is the sliding door 12. This makes it possible to absorb the torque applied to the corrugated tube 32 when the sliding door 12 is opened or closed.

[0086] Moreover, the door support part 40 includes a guide part 56 in which a guide groove 58 is formed, and the bearing-side protector 46 has a slider part 54 supported by the guide part 56 so as to be slidable along the guide groove 58 as the sliding door 12 is opened and closed. As a result, when the sliding door 12 is opened and closed, the part of the corrugated tube 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 if torque is applied to the corrugated tube 32 while the corrugated tube 32 slides relative to the sliding door 12 together with the bearing-side protector 46 and the shaft-side protector 41, the torque applied to the corrugated tube 32 when the sliding door 12 is opened and closed can be absorbed.

[0087] [Note] FIG. 8 is a diagram showing a modified example of the shaft side protector 41 and the bearing side protector 46. In FIG.

[0088] The shaft side protector 141 according to the modified example is a part formed by combining a first divided part 141X and a second divided part 141Y, each having a shape in which the portion through which the wire harness 30 passes is divided along the axial direction. Similarly, the bearing side protector 146 according to the modified example is a part formed by combining a first divided part 146X and a second divided part 146Y, each having a shape in which the portion through which the wire harness 30 passes is divided along the axial direction. This makes it easy to later attach the shaft side protector 141 and the bearing side protector 146 to the wire harness 30 and the corrugated tube 32. The first divided parts 141X, 146X and the second divided parts 141Y, 146Y may be divided in half or in other proportions.

[0089] In the divided parts 146X, 146Y of the bearing side protector 146, a portion that becomes the bearing portion 47 has a rib. A recess is formed in the rib. The rib and recess of the two divided parts 146X, 146Y are combined to form the restricting wall portion 48 and the insertion hole 50. Here, the protective portion 51 of the bearing side protector 146 extends from the outer edge of the rib, not from the periphery of the recess. When the shaft side protector 141 rotates, the portion of the wiring member 31 that extends out from the shaft side protector 141 is held by the periphery of the insertion hole 50.

[0090] The first divided parts 141X, 146X and the second divided parts 141Y, 146Y are fixed to each other by screws, etc. The fixed parts between the first divided parts 141X, 146X and the second divided parts 141Y, 146Y have sufficient rigidity to prevent the cylindrical shape of the shaft part 44 and the bearing part 47 from collapsing even when the torque of the corrugated tube 32, etc. is applied thereto.

[0091] In this modification, the tube holding portion 143 of the shaft side protector 141 covers the corrugated tube 32. This allows the tube holding portion 143 to be attached to the outer periphery of the corrugated tube 32. The tube holding portions 143 of the separate parts 141X, 141Y have protrusions that protrude from the inner surface of the portion that will become the cylindrical main body 42. The protrusions of the two separate parts 141X, 141Y combine to form an annular protrusion that fits around the outside of the small diameter cylindrical portion.

[0092] In the bearing-side protector 146, the slider portion 54 may be provided in either the first divided part 146X or the second divided part 146Y without being divided. A divided slider portion 54 may be provided in each of the first divided part 146X and the second divided part 146Y.

[0093] FIG. 9 is a schematic plan view showing a modified example of the wiring structure 20 of the wire harness.

[0094] In the wiring structure 220 of the modified example, the movable body is the seat 17 on which an occupant sits. The seat 17 has a framework 18A and a cushion 18B. The seat 17 is supported slidably on a slide rail 19 laid on the floor. The sliding direction of the seat 17 is generally the front-rear direction of the vehicle, but may be other directions. The vehicle body support part 70 is supported on the floor. In the wiring structure 220 of the wire harness, the wire harness 230 connects the vehicle body side device and the seat side device. The wire harness 230 has a seat side connector 238. The floating section 35 of the wire harness 230 extends between the floor and the seat 17.

[0095] In this modification, the movable body support part is a seat support part 240. The seat support part 240 includes the shaft side protector 41 and a bearing side protector 246, similar to the door support part 40. The bearing side protector 246 may be configured to include a portion supported by the seat 17, for example, instead of omitting the slider part 54 from the bearing side protector 46. The bearing side protector 246 may be supported by the skeleton 18A of the seat 17, for example. The seat support part 240 does not include the guide part 56 and the urging part 64, etc., of the door support part 40. The seat support part 240 may include the guide part 56 and the urging part 64, etc.

[0096] When the seat 17 moves along the slide rail 19, the free moving section 35 moves and changes its position, and torque may be applied to the corrugated tube 32. The corrugated tube 32 rotates about the central axis relative to the bearing side protector 246 via the shaft side protector 41, thereby absorbing the torque applied to the corrugated tube 32 when the seat 17 slides.

[0097] In addition, although the movable body side support part has been described so far as including the shaft side protector and the bearing side protector, this is not a required configuration. The vehicle body support part may be configured to include the shaft side protector and the bearing side protector. In this case, the movable body side support part may or may not include the shaft side protector and the bearing side protector. In other words, only one of the vehicle body support part and the movable body side support part may be configured to include the shaft side protector and the bearing side protector, or both the vehicle body support part and the movable body side support part may be configured to include the shaft side protector and the bearing side protector.

[0098] Also, the bearing portion of the bearing-side protector may be provided on a slider that moves along the slide rail.

[0099] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually inconsistent. [Explanation of symbols]
