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

[0011] The wiring structure of the wire harness of 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 free 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 vehicle body, wherein at least one of the support part for the vehicle body and the support part for the movable body includes a shaft-side protector having a shaft portion and a tube holding portion, and a bearing-side protector having a bearing portion, the tube holding portion holds the corrugated tube so that their central axes coincide, the shaft-side protector is supported by the bearing-side protector so as to be rotatable around the central axis via the bearing portion and the shaft 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 of (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, because the shaft portion and the bearing portion 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 spherical members.

[0014] (2) In the wiring harness arrangement structure of (1), the tube holding portion may cover the corrugated tube, thereby making it possible to attach the tube holding portion to the outer periphery of the corrugated tube.

[0015] (3) In the wiring structure of the wire harness of (1), the corrugated tube may cover the tube holding portion, thereby making it possible to attach the corrugated tube to the 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 axis 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 of the free-moving section along the extending direction of the wire harness and covers the wire harness. This allows the bearing-side protector to protect the wire harness.

[0018] (6) In the wiring structure of any one of (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 that are separated along the axial direction. This makes it easy to retrofit 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 loosely inserted through the corrugated tube along the extending direction of the wiring member. This makes it difficult for the wiring member inside the corrugated tube to twist when the corrugated tube and the shaft-side protector rotate relative to the bearing-side protector and the corrugated tube twists.

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

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

[0023] (11) Furthermore, a support component of the present disclosure includes a wiring member and a corrugated tube sheathed on the wiring member, and is a support component that supports the vehicle body side section or the movable body side section of a wire harness having a vehicle body side section supported on the 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 a shaft side protector including a shaft 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 shaft side protector is supported by the bearing side protector so as to be rotatable around the central axis via the bearing portion and the shaft 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. Furthermore, because the shaft and bearing parts each have a cylindrical circumferential surface, the structure of the support part can be simplified and made smaller than when supported by a spherical member.

[0025] [Details of the embodiments 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 equivalent to the claims.

[0026] [Embodiment 1] Hereinafter, a wiring structure of a wire harness according to a first embodiment will be described. In this embodiment, FIG. 1 will be used to explain an example in which the movable body is a sliding door. FIG. 1 is a schematic plan view showing a wiring structure 20 of a 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 of a 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 of 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, the relationship between the wiring harness routing structure 20 and the vehicle body 10 and sliding door 12 to which the wiring structure 20 is applied will be described. Note that in Fig. 1, the wiring harness routing structure 20 shown by a solid line indicates a state in which the sliding door 12 is open, and the wiring harness routing structure 20 shown by a two-dot chain line indicates a state in which the sliding door 12 is closed. Also, in Fig. 1, some components 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 entry / exit opening 11 on its side for passengers to enter and exit the vehicle. A sliding door 12 is slidably supported on the vehicle body 10. The entry / exit opening 11 is opened and closed by the sliding door 12 sliding. The sliding door 12 includes a door panel 13 that defines the exterior 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 on a support rail that is disposed on the vehicle body 10. A weatherstrip 16 is disposed around the periphery of the entry / exit opening 11 so as to come into contact with the door panel 13 and the vehicle body 10. For example, the weatherstrip 16 is disposed in an annular shape on the outer periphery 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 (e.g., 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 component 40 that supports the wire harness 30 on the sliding door 12, and a vehicle-body support component 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 door-side devices and vehicle-body-side devices, and a corrugated tube 32 that is sheathed around the wiring member 31. The wiring member 31 may be, for example, an electric wire or an optical fiber cable. The wiring member 31 may be a single piece or multiple pieces. The corrugated tube 32 protects the wiring member 31 and bundles multiple wiring members 31 together. The corrugated tube 32 has a shape in which large-diameter cylindrical sections and small-diameter cylindrical sections, each having 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 sections and the small-diameter cylindrical sections along the extension direction. Note that in FIG. 1, the end portions of the corrugated tube 32 are depicted in a shape that conforms to the original shape of the corrugated tube 32, while the middle portion of the corrugated tube 32 is depicted in a simplified shape that omits the uneven shape. This also applies to FIG. 2 and 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 one another 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 component 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 the floor panel and is covered with 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 around the entrance / exit opening 11, through which the wire harness 30 is led out. The vehicle body support component 70 shown in FIG. 1 supports a portion of the vehicle body side section 33 that is continuous with 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 component 40. The door-side section 34 is held by the sliding door 12 and moves relative to the vehicle body 10 together with the sliding door 12 when the sliding door 12 is opened or closed. Here, a portion of the door-side section 34 is supported by the door support component 40 so as to move along a fixed path relative to the sliding door 12 when the sliding door 12 is opened or closed. The door-side section 34 is disposed between the door panel 13 and the door trim 14, thereby preventing the door-side section 34 from being exposed. A door-side harness opening is provided in the door trim 14 to allow the wire harness 30 to lead out. The door-side harness opening is provided, for example, in the lower part of the door trim 14. The free-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 more freely relative to the vehicle body 10 and the sliding door 12 than 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, thereby moving and changing its position relative to the vehicle body 10 and the sliding door 12. A 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 on 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 on the sliding door 12 by a door support part 40.

[0035] The free-floating section 35 has an exposed section 36. The exposed section 36 is a section that is exposed between the vehicle body 10 and the sliding door 12 when the sliding door 12 is open. Here, the corrugated tube 32 provided in the free-floating section 35 is exposed. For example, the exposed section 36 is a portion of the free-floating 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 occupants getting in and out of the vehicle, such as a position at the rear and below the vehicle entry / exit opening 11. However, because the exposed section 36 is exposed to the entry / exit opening 11, it is difficult to completely prevent it from being stepped on by occupants getting in and out through the entry / exit opening 11. Furthermore, because 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 load. Here, the tension on the exposed section 36 is prevented from increasing when a stepped load is applied to the exposed section 36.

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

[0038] Each part of the wiring structure 20 for the wire harness will be described in more detail. Fig. 2 is a schematic perspective view showing the wiring structure 20 for the wire harness. Fig. 3 is a schematic front view showing the 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 the closed state. Fig. 6 is a schematic front view showing the 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 manner that allows it to move freely along the extension direction. This makes the wiring member 31 less susceptible to external forces acting on the corrugated tube 32. Specifically, the wiring member 31 simply passes through the interior 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 twist. Furthermore, when the middle portion of the corrugated tube 32 is pushed in a direction intersecting the axial direction, the corrugated tube 32 bends as if pulled in the pushed direction, reducing the difference between the concave and convex portions, allowing it to stretch and deform to become longer. In this case, when the wiring member 31 is pushed by the corrugated tube 32, it moves freely along the extension direction, thereby preventing the tension applied to the wiring member 31 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 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 the rigidity of the corrugated tube 32. The cylindrical 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 cylindrical 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, the 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 in the tube holding portion 43 by fitting the annular protrusion into the inside of 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 rotatably supports the shaft portion 44. The bearing portion 47 and the shaft portion 44 each have a cylindrical circumferential surface about 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 in the direction of the central axis CA. A ring-shaped recess 49 into which the flange 45 fits is formed between the pair of restricting wall portions 48. 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, if the corrugated tube 32 is rotated directly around the central axis CA relative to the bearing-side protector 46 by torque, it may not rotate smoothly. In this case, 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 if it were rotated directly relative to the bearing-side protector 46.

[0048] Since the bearing-side protector 46 supports the shaft-side protector 41 so that it can rotate substantially only about the central axis CA, the space required for the movable body support component is reduced compared to when a spherical portion is used. Note that, due to tolerances 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 directions other than about the central axis CA.

[0049] The protective portion 51 is continuous with the bearing portion 47. The protective portion 51 covers the 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 loosely inserted through the shaft-side protector 41 and the bearing-side protector 46 along the extending 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 molded integrally using a mold, or the slider portion 54 may be molded separately from the protective wall portion 52 and then attached to the protective wall portion 52.

[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 that the distance between the first slider portion 54A and the second slider portion 54B is kept constant. .The first slider portion 54A and the second slider portion 54B are provided at positions spaced apart from each other on the outer surface of the protective wall portion 52 along the extension direction of the door-side section 34. Therefore, the protective wall portion 52 can be considered 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 extend while curving 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 component 56 is formed with a guide groove 58 that guides the slider portion 54. The guide component 56 has a plate-shaped guide body 57 that extends along the door panel 13. The guide groove 58 is formed in the guide body 57. The slider portion 54 moves along the guide groove 58 in the guide component 56. The inner peripheral edge of the guide groove 58 fits into the circumferential groove of the slider portion 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 arranged so that the slider portion 54 moves along 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 end of the stress absorption groove 62 opposite the first end 60 is located lower in the vertical direction than the first end 60. The stress absorption groove 62 extends from the first end 60 toward the front 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 only of 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 curved portion 59B1 is on the first end 60B side, and the straight portion 59B2 is on the second end 61B side. 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] Curved portion 59B1 extends in an arc shape centered at first end 60A. Here, curved portion 59B1 is shorter than a quarter-circular arc (an arc of a quadrant). Curved portion 59B1 may be longer than a quarter-circular arc. Straight portion 59B2 extends from the other end of curved portion 59B1 in a tangential direction at the other end of curved portion 59B1. Straight portion 59B2 is longer than both curved portion 59B1 and first opening / closing groove 59A. The extending direction of straight portion 59B2 and the extending direction of first opening / closing groove 59A intersect with each other. First opening / closing groove 59A is inclined more with respect to the horizontal direction than straight portion 59B2. Straight portion 59B2 extends linearly from first end 60 toward the rear of the vehicle parallel to the horizontal direction. The connecting portion between curved portion 59B1 and straight portion 59B2 is located directly below first end 60A. Curved portion 59B1 extends from the connecting portion between curved portion 59B1 and straight portion 59B2 toward the front of the vehicle beyond first end portion 60A. Straight portion 59B2 extends from the connecting portion between curved portion 59B1 and straight portion 59B2 toward the rear of the vehicle beyond first end portion 60A. First end portion 60B is located further forward of the vehicle than first end portion 60A, and second end portion 61B is located further rear of the vehicle than 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 an imaginary extension line of the first stress absorption groove 62A extending downwardly from the vehicle. The first stress absorption groove 62A and the second stress absorption groove 62B are the same length.

[0061] Because the first slider portion 54A and the second slider portion 54B are maintained 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 together while maintaining a constant distance. This distance is the distance between the first end 60A and the first end 60B. In the first open state, the first slider portion 54A is located at the first end 60A, and the second slider portion 54B is located at the first end 60B. The distance between the second end 61A and the second end 61B is the same as the distance between the first end 60A and the first end 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, which is 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 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 force 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 main body 57.

[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 in the extension direction of the first stress-absorbing groove 62A, and is also biased toward the first end portion 60 in the extension direction of the first opening / closing groove 59A.

[0065] The carbody support component 70 supports the carbody side section 33 to the carbody 10 at a position of the carbody side section 33 adjacent to the free-moving section 35. The carbody support component 70 has a tube holding portion 71. The tube holding portion 71 supports the corrugated tube 32 at a fixed position along the extension direction. The tube holding portion 71 may support the corrugated tube 32 rotatably about the central axis CA, or may support it non-rotatably. The carbody support component 70 is attached to the carbody 10 at a fixed position. This holds the carbody 10 side end of the corrugated tube 32 at a fixed position on the carbody 10. The carbody support component 70 is supported non-rotatably on the carbody 10. This holds the carbody 10 side end of the corrugated tube 32 extending from the carbody support component 70 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 and 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 and 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 component 70 positions and fixes the corrugated tube 32 along the extension direction. The wiring member 31 is not fixed to the corrugated tube 32, and therefore 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, thereby being positioned and fixed to the sliding door 12. The portion of the wiring member 31 that passes through the shaft-side protector 41 and the bearing-side protector 46 is free to move relative to the protectors 41, 46 and moves relative to the sliding door 12, and is therefore 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-moving section 35 will now be described in more detail.

[0070] When the sliding door 12 is opened or closed to change between the first open state and the closed state, 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 60B toward the second end 61B, the first slider portion 54A remains at the first end 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 in the direction of the arrow OC2A, the first slider portion 54A rotates while remaining at the first end 60A. 7, when the second slider portion 54B moves along the straight portion 59B2 in the direction of the arrow OC2B, the first slider portion 54A moves along 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 along the first opening / closing groove 59A becomes shorter than the distance that the second slider portion 54B moves along the straight portion 59B2.

[0071] In the first open state, most of the sliding door 12 is located rearward of the entry / 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 entry / exit opening 11, and as a result, 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 each positioned in the linear groove. As a result, when the first slider portion 54A is biased toward the first end 60A in the closed state, the first slider portion 54A and the second slider portion 54B easily move toward the first end 60A and the first end 60B. Slack may occur in the free movement section 35 in the closed state. Even in this case, the movement of the first slider portion 54A and the second slider portion 54B toward the first end 60A and the first end 60B makes it easier for the free movement section 35 to be in a state where it is appropriately tensioned, making it less likely for slack to occur in the free movement section 35. As a result, the portion of the free movement section 35 that extends beyond the door trim 14 in the closed state is less likely 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 released, changing the state between the first open state and the second open state, the first slider portion 54A moves along the first stress-absorbing groove 62A, and the second slider portion 54B moves along the second stress-absorbing groove 62B. The distance that the first slider portion 54A moves along the first stress-absorbing groove 62A is the same as the distance that the second slider portion 54B moves along the second stress-absorbing groove 62B. More specifically, in FIG. 7 , when the second slider portion 54B moves along the second stress-absorbing groove 62B in the direction of arrow SL2, the first slider portion 54A moves along the first stress-absorbing groove 62A in the direction of 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 tread load F is applied, can move up to the rigid part. After the exposed section 36, to which the tread load F is applied, reaches the rigid part, the rigid part supports the exposed section 36 from below, making it difficult for the tread 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 tread load F is applied, from moving below the step.

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

[0077] In the second open state, the first slider portion 54A and the second slider portion 54B are each positioned in the linear groove portion. 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 due to the urging force of the urging portion 64.

[0078] The angle between the extension direction of the first stress-absorbing 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 60 along the first stress-absorbing groove 62A and the first opening / closing groove 59A, the biasing force of the biasing portion 64 is greater when the first slider portion 54A moves along the first stress-absorbing groove 62A.

[0079] The wiring member 31 is not fixed to the corrugated tube 32 and the protectors 41, 46, and is free to move relative to the corrugated tube 32 and the protectors 41, 46 in the extension direction. During the above-described state change, 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, changing its posture to follow the corrugated tube 32 and the protectors 41, 46. At this time, the portions of the wiring member 31 that are pushed by the corrugated tube 32 and the protectors 41, 46 change as appropriate. Even in this case, the wiring member 31 moves freely relative to the corrugated tube 32 and the protectors 41, 46 in the extension direction, thereby preventing excessive tension in the portions of the wiring member 31 that are pushed by the corrugated tube 32 and the protectors 41, 46.

[0080] <Effects, etc.> According to the door support component 40 and the wiring harness routing structure 20 including the door support component 40 configured as described above, when 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. Furthermore, because the shaft portion 44 and the bearing portion 47 each have a cylindrical peripheral surface, the configuration of the door support component 40 can be simplified and the size of the door support component 40 can be reduced compared to when supported by spherical members. Furthermore, because the torque applied to the corrugated tube 32 is absorbed by the door support component 40, the configuration of the vehicle body support component 70 can be simplified and the vehicle body support component 70 can also be reduced in size.

[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 that corresponds 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 has an annular recess 49 into which the flange 45 fits. This allows the shaft-side protector 41 and the bearing-side protector 46 to have simple shapes, while allowing the shaft-side protector 41 to rotate smoothly relative to 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 of the free-moving 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] Furthermore, the wiring member 31 is loosely inserted along the extension direction of the corrugated tube 32. 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] 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] The door support component 40 also includes a guide component 56 in which a guide groove 58 is formed, and the bearing-side protector 46 has a slider portion 54 supported by the guide component 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 portion of the corrugated tube 32 that is 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, the torque applied to the corrugated tube 32 when the sliding door 12 is opened and closed can be absorbed while the corrugated tube 32 slides together with the bearing-side protector 46 and the shaft-side protector 41 relative to the sliding door 12.

[0087] [Note] FIG. 8 shows 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 component formed by combining a first divided part 141X and a second divided part 141Y, each having a shape divided along the axial direction at the portion through which the wire harness 30 passes. Similarly, the bearing-side protector 146 according to the modified example is a component formed by combining a first divided part 146X and a second divided part 146Y, each having a shape divided along the axial direction at the portion through which the wire harness 30 passes. This makes it easy to retrofit 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 may be divided in other proportions.

[0089] The divided parts 146X, 146Y of the bearing-side protector 146 have ribs at the portions that become the bearing parts 47. Recesses are formed in the ribs. The ribs and recesses of the two divided parts 146X, 146Y combine to form the restriction wall parts 48 and the insertion holes 50. Here, the protective parts 51 of the bearing-side protector 146 extend from the outer edges of the ribs, not from the peripheries of the recesses. When the shaft-side protector 141 rotates, the parts of the wiring member 31 that extend out from the shaft-side protector 141 are held by the peripheries of the insertion holes 50.

[0090] The first divided parts 141X, 146X and the second divided parts 141Y, 146Y are fixed with 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 torque from the corrugated tube 32 is applied.

[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 and 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 and 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. Alternatively, 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 harness routing structure 20. In FIG.

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

[0095] In this modified example, the movable body support component is a seat support component 240. The seat support component 240 includes the shaft-side protector 41 and a bearing-side protector 246, similar to the door support component 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 portion 54 from the bearing-side protector 46. The bearing-side protector 246 may be supported by the framework 18A of the seat 17, for example. The seat support component 240 does not include the guide component 56, the biasing component 64, etc., of the door support component 40. The seat support component 240 may include the guide component 56, the biasing component 64, etc.

[0096] When the seat 17 moves along the slide rail 19, the free-floating section 35 moves and changes its position, which may apply torque to the corrugated tube 32. The corrugated tube 32 rotates about its 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, until now, forAlthough the support component has been described as including the shaft side protector and the bearing side protector, this is not a necessary configuration. The vehicle body support component may be configured to include the shaft side protector and the bearing side protector. In this case, the movable body for The support part may or may not include a shaft side protector and a bearing side protector. for The support part and the movable body may be configured to include the shaft side protector and the bearing side protector, or the support part and the movable body may be configured to include the shaft side protector and the bearing side protector. for Both the support component and the bearing component may be configured to include a shaft-side protector and a bearing-side protector.

[0098] Furthermore, 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 contradictory. [Explanation of symbols]
