[0003] [Patent Document 1] JP 2011-151906 A Summary of the Invention [Problem to be solved by the invention]

[0004] When the wiring structure between the car body and the sliding body has an exterior member, the inventor of the present application has considered disposing a biasing member having rigidity inside the exterior member. Here, when the biasing member is curved in the narrow space between the car body and the sliding body, the biasing member is likely to have a tapered shape at the curved portion. If the curved portion has a tapered shape, this leads to a decrease in the bending radius of the electric wire.

[0005] An object of the present invention is to provide a wiring structure that can suppress the tapered shape of a biasing member. [Means for solving the problem]

[0006] The wiring structure of the present invention includes a first fixing portion fixed to a rail extending in the vehicle front-rear direction and disposed on the vehicle body of the vehicle, a second fixing portion fixed to a slide body that moves along the vehicle front-rear direction with respect to an opening provided in the roof of the vehicle body, a first end portion held by the first fixing portion, a second end portion held by the second fixing portion, a cylindrical exterior member having the above, an electric wire inserted through the exterior member, a biasing member inserted through the exterior member and having a curved portion that curves in the vehicle front-rear direction at a position between the first end portion and the second end portion, and a support structure that supports the biasing member. The support structure has at least one of a first support structure that forms a first arc portion in the curved portion and a second support structure that forms a second arc portion in the curved portion. The first arc portion is formed in a portion of the curved portion along the rail and has an arc shape that protrudes downward in the vehicle vertical direction. The second arc portion is formed in a portion of the curved portion along the slide body and has an arc shape that protrudes upward in the vehicle vertical direction.

Effect of the Invention

[0007] The wiring structure according to the present invention has a support structure that supports a biasing member. The support structure has at least one of a first support structure that forms a first arc portion in the curved portion and a second support structure that forms a second arc portion in the curved portion. The first arc portion is formed in a portion of the curved portion along the rail and has an arc shape that protrudes downward in the vehicle vertical direction. The second arc portion is formed in a portion of the curved portion along the slide body and has an arc shape that protrudes upward in the vehicle vertical direction. According to the wiring structure of the present invention, by forming at least one of the first arc portion and the second arc portion, there is an effect that the tapered shape of the biasing member can be suppressed.

In FIG. 3, the cross-section III-III of FIG. 4 is shown.

[0011] As shown in Fig. 1, a wiring structure 1 of the embodiment is applied to a sunroof 200 of a vehicle 100. The vehicle 100 is, for example, an automobile equipped with a power source such as a motor or an engine. The vehicle 100 has a vehicle body 110. The vehicle body 110 has a roof 120 that covers the passenger compartment. The roof 120 has an opening 120a that opens upward.

[0012] The vehicle 100 has a sunroof 200 that opens and closes the opening 120a. The sunroof 200 has a sliding body 210, a rail 220, and a wiring structure 1. The sliding body 210 is a member that slides along the vehicle front-rear direction X with respect to the opening 120a. The sliding body 210 of this embodiment is a plate-like member that closes or opens the opening 120a. The sliding body 210 may be glass that is configured to be able to transmit light.

[0013] The sunroof 200 has a mechanism such as a link mechanism that moves the sliding body 210 along a predetermined path, and a drive source such as a motor that operates the mechanism. The sunroof 200 moves the sliding body 210 between a fully closed position where the opening 120a is closed and a fully open position where the opening 120a is opened. Figure 1 shows the sliding body 210 in the fully closed position. Figure 2 shows the sliding body 210 in the fully open position.

[0014] The rail 220 is fixed to the vehicle body 110. The rail 220 is disposed on a lower side Y2 of the sliding body 210 and extends in the vehicle front-rear direction X. The rail 220 supports a mechanism that moves the sliding body 210 and guides this mechanism in the vehicle front-rear direction X. The rail 220 further supports the exterior member 30 and forms a first extension portion 31 in the exterior member 30.

[0015] The sunroof 200 of this embodiment moves the sliding body 210 along a path AR0 shown in Fig. 2. The movement of the sliding body 210 along the path AR0 includes movement along the vehicle front-rear direction X and movement along the vehicle up-down direction Y. When the sliding body 210 moves from the fully closed position to the fully open position, as shown by the arrow AR1 in Fig. 2, the sliding body 210 moves toward the upper side Y1 in the vehicle up-down direction Y and toward the rear side X2 in the vehicle front-rear direction X.

[0016] Conversely, when the slide body 210 moves from the fully open position to the fully closed position, the slide body 210 moves toward the front side X1 in the vehicle longitudinal direction X and moves toward the lower side Y2 in the vehicle vertical direction Y.

[0017] 1 to 3, the wiring structure 1 has a first fixing portion 10, a second fixing portion 20, an exterior member 30, an electric wire W, and a biasing member 50. The exterior member 30 and the electric wire W configure a wire harness that is wired between the vehicle body 110 and the slide body 210.

[0018] The first fixed part 10 is a member fixed to the vehicle body 110 of the vehicle 100. The first fixed part 10 of the present embodiment is fixed to a rail 220. The first fixed part 10 may be a protector that protects the electric wire W. The first fixed part 10 is molded, for example, from an insulating synthetic resin. The first fixed part 10 has a space in which the electric wire W is routed, and has a holding structure that holds the exterior member 30.

[0019] The second fixing part 20 is a member fixed to the sliding body 210 of the sunroof 200. The second fixing part 20 may be a protector that protects the electric wires W. The second fixing part 20 is molded, for example, from an insulating synthetic resin. The second fixing part 20 has a space in which the electric wires W are routed, and has a holding structure that holds the exterior member 30.

[0020] The exterior member 30 is a cylindrical member that is elastically deformable. The exterior member 30 is, for example, a member called a corrugated tube. The exterior member 30 is molded, for example, from an insulating synthetic resin. The exterior member 30 may have a bellows shape.

[0021] The exterior member 30 has a first end 30a held by the first fixing part 10 and a second end 30b held by the second fixing part 20. The first fixing part 10 holds the first end 30a such that the exterior member 30 extends from the first fixing part 10 along the rail 220 in the vehicle front-rear direction X. The first fixing part 10 of the present embodiment holds the first end 30a such that the exterior member 30 extends from the first fixing part 10 toward the front side X1.

[0022] The second fixing portion 20 holds the second end portion 30b such that the exterior member 30 extends from the second fixing portion 20 along the slide body 210 in the vehicle front-rear direction X. The second fixing portion 20 of the present embodiment holds the second end portion 30b such that the exterior member 30 extends from the second fixing portion 20 toward the front side X1.

[0023] An electric wire W and a biasing member 50 are inserted into the exterior member 30. The electric wire W is, for example, a coated electric wire having a twisted wire and a coating. The electric wire W may be a flat wiring material, a printed circuit body, or other circuit body. The electric wire W drawn out from the first end portion 30a is connected to a power source or a control device arranged in the vehicle body 110. The electric wire W drawn out from the second end portion 30b is connected to a load arranged on the side of the sliding body 210. The load arranged on the sliding body 210 may be, for example, a lighting device, a light control film arranged on the glass of the sliding body 210, or other electric load.

[0024] As shown in Figs. 1 and 2, the exterior member 30 has curved portions 33, 34 that are curved in the vehicle front-rear direction X between the first end portion 30a and the second end portion 30b. The curved portions 33, 34 are formed by a biasing member 50. The curved portion 33 shown in Fig. 1 is a curved portion formed in the exterior member 30 when the sliding body 210 is in the fully closed position. The curved portion 33 has a radius R1. The curved portion 34 shown in Fig. 2 is a curved portion formed in the exterior member 30 when the sliding body 210 is in the fully open position. The curved portion 34 has a radius R2. The electric wire W on which the curved portions 33, 34 are formed has a U-shape or a J-shape.

[0025] 1, when the sliding body 210 is in the fully closed position, the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y is a first distance L1. The radius R1 of the curved portion 33 is half the first distance L1.

[0026] 2, when the sliding body 210 is in the fully open position, the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y is a second distance L2. The radius R2 of the curved portion 34 is half the second distance L2.

[0027] In the sunroof 200 of this embodiment, the second distance L2 in the fully open position is greater than the first distance L1 in the fully closed position. Therefore, the radius R1 of the curved portion 33 when the sliding body 210 is in the fully closed position is smaller than the radius R2 of the curved portion 34 when the sliding body 210 is in the fully open position. Also, the radius R1 when the sliding body 210 is in the fully closed position is smaller than the radius of the curved shape formed in the biasing member 50 when the sliding body 210 is in another position. In other words, the magnitude of the radius of the curved shape formed in the biasing member 50 is minimum when the sliding body 210 is in the fully closed position.

[0028] The second end 30b of the exterior member 30 moves together with the slider 210. At this time, the exterior member 30 follows the movement of the second fixing portion 20 while gradually changing the position where the curved shape is formed.

[0029] The biasing member 50 of this embodiment is a member that presses the exterior member 30 toward the sliding body 210. The biasing member 50 of this embodiment is a plate-shaped member that is elastically deformable. The biasing member 50 is made of metal or resin. The biasing member 50 extends from the first end 30a to the second end 30b of the exterior member 30.

[0030] As shown in Fig. 3, the cross-sectional shape of the exterior member 30 of this embodiment is rectangular. The shape of the urging member 50 illustrated is a substantially flat plate shape. In the urging member 50, the cross-sectional shape perpendicular to the axial direction of the urging member 50 is rectangular. The urging member 50 extends from one end to the other end in the width direction H in the internal space of the exterior member 30. The urging member 50 faces each of the multiple electric wires W in the vehicle up-down direction Y. In other words, the urging member 50 has a width capable of supporting the multiple electric wires W.

[0031] The urging member 50 in Fig. 3 is disposed on the outer side with respect to the electric wire W. Therefore, at the curved portions 33, 34, the urging member 50 is located on the radially outer side with respect to the electric wire W. As shown in Fig. 3, the urging member 50 contacts the exterior member 30 and applies pressing forces F1, F2 to the exterior member 30 at the contact surface.

[0032] 4, the exterior member 30, the electric wire W, and the biasing member 50 are arranged in a curved U-shape or J-shape. That is, the biasing member 50 extends from the first fixed portion 10 to the second fixed portion 20 in a state in which the biasing member 50 has a curved portion 54.

[0033] The biasing member 50 bent to have the curved portion 54 applies pressing forces F1 and F2 to the exterior member 30. The pressing force F1 is a force in the vehicle up-down direction Y, and presses the exterior member 30 toward the rail 220. The pressing force F2 is a force in the vehicle up-down direction Y, and presses the exterior member 30 toward the slide body 210. The pressing forces F1 and F2 are restoring forces generated in the bent biasing member 50.

[0034] The pressing force F1 forms a first extending portion 31 in the exterior member 30. The pressing force F2 forms a second extending portion 32 in the exterior member 30. As shown in Fig. 2 etc., the second extending portion 32 is a portion extending along a vehicle interior side surface 210a of the sliding body 210. The vehicle interior side surface 210a is a surface facing the lower side Y2.

[0035] The biasing member 50 of this embodiment is configured to press the exterior member 30 toward the sliding body 210 when the sliding body 210 is in the fully closed position and when the sliding body 210 is in the fully open position. In other words, the biasing member 50 has a rigidity that can constantly press the exterior member 30 toward the sliding body 210 and keep it in contact with it. Therefore, the wiring structure 1 of this embodiment can stabilize the shape of the exterior member 30. For example, the biasing member 50 can keep the exterior member 30 in contact with the sliding body 210 against an external force such as vibration generated during driving.

[0036] As described below, the wiring structure 1 of this embodiment is configured to suppress the tapered shape of the urging member 50. First, the tapered shape formed on the urging member will be described.

[0037] 5 shows a tapered shape formed in the biasing member 150 of the comparative example. The biasing member 150 of the comparative example has a plate shape similar to the biasing member 50 of the embodiment. The biasing member 150 is formed with a curved portion 151 and a straight portion 152. The straight portion 152 is a portion that extends linearly, and is formed along each of the slide body 210 and the rail 220.

[0038] The curved portion 151 has a tip portion 151a and two end portions 151b. The tip portion 151a is a central portion of the curved portion 151, and has a convex shape facing the vehicle front-rear direction X. The end portions 151b are end portions of the curved portion 151 in the vehicle up-down direction Y, and are portions that connect to the straight portion 152. The curved portion 151 has a tapered shape. More specifically, the shape of the curved portion 151 is such that the bending radius becomes smaller from the end portions 151b toward the tip portion 151a.

[0039] 5 shows an imaginary circle IC. The imaginary circle IC is a circle whose diameter is the distance L0 from the rail 220 to the slide body 210 in the vehicle up-down direction Y. The bending radius of the tip end 151a is smaller than the radius of the imaginary circle IC. In the curved portion 151 having a tapered shape, the bending radius of the tip end 151a is smaller than the bending radius of the end end 151b.

[0040] A possible reason why the curved portion 151 is tapered is the reaction force acting on the end portion 151b. In the biasing member 150 shown in FIG. 5, the straight portion 152 is supported by the slide body 210 and the rail 220. In this case, the end portion 151b is a portion whose shape gradually changes from a straight shape to an arc shape. In the following description, the range in which the shape of the biasing members 50, 150 gradually changes from a straight shape to an arc shape is simply referred to as the "gradual change range."

[0041] As shown by the arrow AR3 in Fig. 5, a force acts on the end portion 151b in the vehicle vertical direction Y, which tends to make the end portion 151b closer to a straight shape. This force tends to make the bending radius of the end portion 151b larger than the radius of the imaginary circle IC. As a result, it is considered that a tapered shape is formed in which the bending radius of the tip portion 151a is smaller than the radius of the imaginary circle IC.

[0042] Fig. 6 shows the curved portion 54 formed in the urging member 50 of this embodiment. Note that in Fig. 6, the electric wire W and the exterior member 30 are omitted in order to explain the shape of the curved portion 54. The curved portion 54 formed in the urging member 50 of this embodiment has a first arc portion 55 and a second arc portion 56.

[0043] The first arc portion 55 is formed in a portion of the curved portion 54 that is along the rail 220. The first arc portion 55 has a convex arc shape toward the lower side Y2 in the vehicle vertical direction Y. In other words, the first arc portion 55 faces the rail 220 and is curved toward the rail 220. The first arc portion 55 has an apex 55a that is the lower end of the curved portion 54.

[0044] The first arc portion 55 has inclined portions 55b and 55c on both the front side X1 and the rear side X2 with respect to the vertex 55a. The first inclined portion 55b is located on the front side X1 with respect to the vertex 55a. The second inclined portion 55c is located on the rear side X2 with respect to the vertex 55a. The first inclined portion 55b and the second inclined portion 55c are inclined so as to go upward toward the upper side Y1 as they move away from the vertex 55a. That is, the two inclined portions 55b and 55c are inclined with respect to the rail 220 and move away from the rail 220 as they move away from the vertex 55a. The first inclined portion 55b and the second inclined portion 55c each have an arc shape.

[0045] The biasing member 50 has a first extending portion 51 that extends linearly from the first arc portion 55 toward the first fixing portion 10. The boundary 55d between the first arc portion 55 and the first extending portion 51 is located on the rear side X2 with respect to the vertex 55a.

[0046] By forming the second inclined portion 55c in the biasing member 50, the creep range shifts to the side of the first extending portion 51. In other words, the creep range includes the portion on the rear side X2 with respect to the vertex 55a in the biasing member 50. As a result, the bending radius of the first inclined portion 55b becomes close to the radius of the virtual circle IC determined by the distance L0, and the tapered shape in the curved portion 54 is suppressed.

[0047] The second arc portion 56 is formed in a portion along the slide body 210 in the curved portion 54. The second arc portion 56 has an arc shape convex toward the upper side Y1 in the vehicle vertical direction Y. That is, the second arc portion 56 faces the vehicle compartment side surface 210a of the slide body 210 and is curved toward the vehicle compartment side surface 210a. The second arc portion 56 has a vertex 56a that is the upper end of the curved portion 54.

[0048] The second arc portion 56 has inclined portions 56b, 56c on both the front side X1 and the rear side X2 with respect to the apex 56a. The first inclined portion 56b is located on the front side X1 with respect to the apex 56a. The second inclined portion 56c is located on the rear side X2 with respect to the apex 56a. The first inclined portion 56b and the second inclined portion 56c are inclined toward the lower side Y2 as they move away from the apex 56a. In other words, the two inclined portions 56b, 56c are each inclined with respect to the surface 210a on the passenger compartment side, and move away from the surface 210a on the passenger compartment side as they move away from the apex 56a. The first inclined portion 56b and the second inclined portion 56c each have an arc shape.

[0049] The biasing member 50 has a second extending portion 52 that extends linearly from the second arc portion 56 toward the second fixed portion 20. A boundary 56d between the second arc portion 56 and the second extending portion 52 is located on the rear side X2 relative to the apex 56a.

[0050] By forming the second inclined portion 56c in the urging member 50, the gradual change range is shifted toward the second extending portion 52. In other words, the gradual change range includes a portion X2 rearward of the apex 56a in the urging member 50. As a result, the bending radius of the first inclined portion 56b becomes close to the radius of the imaginary circle IC determined by the distance L0, and the tapered shape of the curved portion 54 is suppressed.

[0051] The wiring structure 1 of this embodiment has a support structure 4 that forms a first arc portion 55 and a second arc portion 56. The support structure 4 of this embodiment has both a first support structure 41 and a second support structure 42, which will be described later.

[0052] As will be described with reference to Fig. 7, the first arc portion 55 is formed by a first support structure 41. The illustrated first support structure 41 is provided on the first fixed portion 10. The first support structure 41 has a support surface 11. The support surface 11 is a surface of the first fixed portion 10, and faces an upper side Y1 in the vehicle vertical direction Y. The support surface 11 is spaced apart from the rail 220, and is located on the upper side Y1 with respect to the rail 220.

[0053] The support surface 11 supports a first end 50a of the urging member 50. The first end 50a is an end corresponding to the first end 30a of the exterior member 30. The first end 50a may be fixed to the support surface 11 by a fixing member 12. The fixing member 12 may be an adhesive tape or a band member such as a cable tie. The support surface 11 supports the first end 50a at a position spaced apart from the rail 220. This forms a first arc portion 55 and a first extension portion 51 in the urging member 50. The relative position of the support surface 11 with respect to the rail 220 is determined so that a first arc portion 55 having an appropriate shape can be formed.

[0054] 7 shows the biasing member 50 when the sliding body 210 is in the fully open position. In this case, the curved portion 54 of the biasing member 50 forms the curved portion 34 in the fully open position in the exterior member 30. Since the tapered shape of the curved portion 54 is suppressed in the fully open position, a decrease in the bending durability of the electric wire W is suppressed.

[0055] As will be described with reference to FIG. 8, the second arc portion 56 is formed by the second support structure 42. The illustrated second support structure 42 is provided on the second fixed portion 20. The second support structure 42 has a support surface 21 and a clamping portion 22. The support surface 21 is a surface of the second fixed portion 20, and faces the lower side Y2 in the vehicle vertical direction Y. The support surface 21 is spaced apart from the slide body 210, and is located on the lower side Y2 with respect to the slide body 210. The support surface 21 is an inclined surface inclined with respect to the vehicle longitudinal direction X. The support surface 21 is inclined so as to move away from the slide body 210 as it approaches the rear side X2 in the vehicle longitudinal direction X.

[0056] The support surface 21 supports the second end 50b of the urging member 50. The second end 50b is an end corresponding to the second end 30b of the exterior member 30. A part of the second end 50b is clamped by the clamping portion 22. The clamping portion 22 holds the second end 50b by clamping it from both sides in the vehicle up-down direction Y. The clamping portion 22 clamps, for example, a portion of the second end 50b on the rear side X2.

[0057] The support surface 21 supports the second end portion 50b at a position spaced apart from the sliding body 210. This forms a second arc portion 56 and a second extension portion 52 in the urging member 50. The relative position of the support surface 21 with respect to the sliding body 210 is determined so as to form the second arc portion 56 having an appropriate shape.

[0058] 8 shows the biasing member 50 when the sliding body 210 is in the fully closed position. In this case, the curved portion 54 of the biasing member 50 forms the curved portion 33 in the fully closed position in the exterior member 30. In the fully closed position, the distance between the rail 220 and the sliding body 210 in the vehicle up-down direction Y is narrowest. By suppressing the tapered shape of the curved portion 54 in the fully closed position, a decrease in the bending durability of the electric wire W is suppressed.

[0059] The support surface 21 can regulate the inclination angle of the second extension portion 52. Furthermore, the support surface 21 can stabilize the shape of the second extension portion 52 and suppress vibration of the second extension portion 52. The portion having the support surface 21 may be formed of rubber or the like capable of absorbing vibration.

[0060] As shown in Fig. 7, the wiring structure 1 of this embodiment is configured to form both a first arc portion 55 and a second arc portion 56 in the curved portion 54 when the sliding body 210 is in the fully open position. The second support structure 42 is configured to be able to form the second arc portion 56 when the sliding body 210 is in the fully open position. For example, the position of the clamping portion 22 shown in Fig. 8 in the vehicle up-down direction Y is determined so that the second arc portion 56 can be formed in the fully open position.

[0061] When the sliding body 210 moves, the urging member 50 may move away from the support surface 21 as shown in Fig. 9. For example, when the sliding body 210 moves toward the rear side X2 from the fully closed position toward the fully open position, the curved portion 54 of the urging member 50 moves away from the second fixed portion 20. At this time, the second end portion 50b of the urging member 50 may move away from the support surface 21. The clamping portion 22 can hold the second end portion 50b at a position away from the sliding body 210 and form a second arc portion 56 in the curved portion 54.

[0062] As shown in Fig. 8, the wiring structure 1 of this embodiment is configured to form both a first arc portion 55 and a second arc portion 56 in the curved portion 54 when the sliding body 210 is in the fully closed position. The first support structure 41 is configured to be able to form the first arc portion 55 when the sliding body 210 is in the fully closed position. For example, the position of the support surface 11 shown in Fig. 7 in the vehicle up-down direction Y is determined to be able to form the first arc portion 55 in the fully closed position.

[0063] The support structure 4 may be configured to form both the first arc portion 55 and the second arc portion 56 when the sliding body 210 is in any position from the fully closed position to the fully open position. Such a support structure 4 is realized by the first support structure 41 and the second support structure 42 as described above. For example, the second support structure 42 configured to be able to form the second arc portion 56 when the sliding body 210 is in the fully open position can always form the second arc portion 56 when the sliding body 210 is in any position from the fully closed position to the fully open position. For example, the first support structure 41 configured to be able to form the first arc portion 55 when the sliding body 210 is in the fully closed position can always form the first arc portion 55 when the sliding body 210 is in any position from the fully closed position to the fully open position.

[0064] The support surface 11 of the first support structure 41 may be an inclined surface inclined with respect to the rail 220. In this case, the support surface 11 is inclined so as to move away from the rail 220 toward the rear side X2 in the vehicle front-rear direction X. The support surface 21 of the second support structure 42 does not have to be inclined with respect to the slide body 210.

[0065] The first support structure 41 may be a member separate from the first fixed portion 10. For example, a first support member having a support surface 11 may be provided adjacent to the first fixed portion 10. The first support member may have a fixed member 12. The second support structure 42 may be a member separate from the second fixed portion 20. For example, a second support member having a support surface 21 may be provided adjacent to the second fixed portion 20. The second support member may have a clamping portion 22.

[0066] The support structure 4 may have only one of the first support structure 41 and the second support structure 42. For example, the support structure 4 may have the first support structure 41 and not have the second support structure 42. In this case, the second extension portion 52 can extend while contacting the sliding body 210. For example, the support structure 4 may have the second support structure 42 and not have the first support structure 41.

[0067] As described above, the wiring structure 1 of the present embodiment includes the first fixing portion 10, the second fixing portion 20, the exterior member 30, the electric wire W, the biasing member 50, and the support structure 4. The first fixing portion 10 is fixed to the rail 220. The rail 220 is disposed on the vehicle body 110 of the vehicle 100 and extends in the vehicle front-rear direction X. The second fixing portion 20 is fixed to the slide body 210. The slide body 210 extends along the vehicle front-rear direction X with respect to the opening 120a provided in the roof 120 of the vehicle body 110. The exterior member 30 is a cylindrical member having a first end portion 30a held by the first fixing portion 10 and a second end portion 30b held by the second fixing portion 20. The electric wire W and the biasing member 50 are inserted into the exterior member 30.

[0068] The urging member 50 has a curved portion 54 that curves toward the vehicle front-rear direction X at a position between the first end 30a and the second end 30b. The support structure 4 supports the urging member 50. The support structure 4 has at least one of a first support structure 41 and a second support structure 42. The first support structure 41 forms a first arc portion 55 in the curved portion 54. The second support structure 42 forms a second arc portion 56 in the curved portion 54.

[0069] The first arc portion 55 is formed in a portion of the curved portion 54 that is aligned with the rail 220, and has a convex arc shape toward the lower side Y2 in the vehicle vertical direction Y. The second arc portion 56 is formed in a portion of the curved portion 54 that is aligned with the slide body 210, and has a convex arc shape toward the upper side Y1 in the vehicle vertical direction Y. The wiring structure 1 of the present embodiment can suppress the tapered shape of the curved portion 54 of the urging member 50 by forming at least one of the first arc portion 55 and the second arc portion 56 in the curved portion 54 of the urging member 50.

[0070] The first arc portion 55 of this embodiment has a vertex 55a which is the lower end of the curved portion 54, and a pair of inclined portions 55b, 55c formed on both sides of the vertex 55a in the vehicle front-rear direction X. The pair of inclined portions 55b, 55c are inclined toward the upper side Y1 in the vehicle vertical direction Y as they move away from the vertex 55a. The first arc portion 55 having such a shape can prevent the curved portion 54 from tapering.

[0071] The second arc portion 56 of the present embodiment has a vertex 56a which is the upper end of the curved portion 54, and a pair of inclined portions 56b, 56c formed on both sides of the vertex 56a in the vehicle longitudinal direction X. The pair of inclined portions 56b, 56c are inclined toward the lower side Y2 in the vehicle vertical direction Y as they move away from the vertex 56a. The second arc portion 56 having such a shape can prevent the curved portion 54 from tapering.

[0072] The sliding body 210 of this embodiment moves between a fully closed position where the opening 120a is closed and a fully open position where the opening 120a is opened. The support structure 4 has both a first support structure 41 and a second support structure 42. The first support structure 41 is configured so that the first arc portion 55 can be formed when the sliding body 210 is in any position from the fully closed position to the fully open position. The second support structure 42 is configured so that the second arc portion 56 can be formed when the sliding body 210 is in any position from the fully closed position to the fully open position. The first arc portion 55 and the second arc portion 56 are always formed, so that the tapered shape of the curved portion 54 is appropriately suppressed.

[0073] The arrangement and structure of the first support structure 41 and the second support structure 42 are not limited to the arrangement and structure exemplified in the embodiment. The exterior member 30 is not limited to a so-called corrugated tube. The exterior member 30 may be a braided tube or other members used as exterior members.

[0074] The urging member 50 may be disposed on the inner side with respect to the electric wire W. That is, the urging member 50 may be disposed on the inner side in the radial direction of the electric wire W at the curved portions 33, 34. The urging member 50 is not limited to a plate-shaped member. The urging member 50 may be a round bar having a circular cross-sectional shape, or may be a rod-shaped member having a polygonal cross-sectional shape.
