[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-151906 Summary of the Invention [Problem to be solved by the invention]

[0004] The inventors of the present application have considered disposing a rigid biasing member inside an exterior member in a wiring structure between a vehicle body and a slide body. Here, from the viewpoint of ensuring the durability of the biasing member against bending, it is preferable to reduce the rigidity of the biasing member. On the other hand, when a curved portion is formed in the exterior member and the biasing member, if the rigidity of the biasing member is low, the curved portion is likely to have a tapered shape. A tapered shape of the curved portion leads to a reduction in the bending radius of the electric wire.

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

[0006] The wiring structure of the present invention is characterized by comprising: an exterior member having a first fixed portion fixed to the body of a vehicle; a second fixed portion fixed to a sliding body that moves in the fore-and-aft direction of the vehicle relative to an opening provided in the roof of the vehicle body; a first end portion held by the first fixed portion; and a second end portion held by the second fixed portion; an electric wire inserted into the exterior member; a plate-shaped biasing member that is inserted into the exterior member and forms a curved portion that curves in the fore-and-aft direction of the vehicle between the first end portion and the second end portion of the exterior member; and a suppression portion that is provided on the biasing member and improves the rigidity of a portion that forms the curved portion to suppress a tapered shape of the biasing member at the curved portion. [Effects of the Invention]

[0007] The wiring structure according to the present invention has a suppression portion provided on the biasing member. The suppression portion improves the rigidity of the portion forming the curved portion and suppresses the tapered shape of the biasing member at the curved portion. The wiring structure according to the present invention has the effect of suppressing the tapered shape of the biasing member. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, a wiring structure according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiment. Furthermore, the components in the following embodiments include those that can be easily imagined by a person skilled in the art or those that are substantially the same.

[0010] [Embodiment] An embodiment will be described with reference to Fig. 1 to Fig. 10. This embodiment relates to a wiring structure. Fig. 1 and Fig. 2 are side views of the wiring structure according to the embodiment, Fig. 3 is a cross-sectional view of the wiring structure according to the embodiment, Fig. 4 is a side view of the wiring structure according to the embodiment, Fig. 5 is a diagram illustrating the tapered shape, and Figs. 6 to 10 are side views of the suppression section according to the embodiment. Fig. 3 shows a cross section taken along line III-III in Fig. 4.

[0011] As shown in FIG. 1, the 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 slider 210, a rail 220, and a wiring structure 1. The slider 210 is a member that slides relative to the opening 120a along the vehicle longitudinal direction X. In this embodiment, the slider 210 is a plate-like member that closes or opens the opening 120a. The slider 210 may be glass that is configured to allow light to pass through.

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

[0014] The rail 220 is fixed to the vehicle body 110. The rail 220 extends in the vehicle longitudinal direction X. The rail 220 supports a mechanism that moves the slider 210 and guides this mechanism in the vehicle longitudinal direction X. The rail 220 further supports the exterior member 30 and forms a first extending portion 31 in the exterior member 30.

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

[0016] Conversely, when the slider 210 moves from the fully open position to the fully closed position, the slider 210 moves toward the front side X1 in the vehicle longitudinal direction X and 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 constitute a wire harness that is wired between the vehicle body 110 and the sliding body 210.

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

[0019] The second fixing portion 20 is a member fixed to the sliding body 210 of the sunroof 200. The second fixing portion 20 may be a protector that protects the electric wires W. The second fixing portion 20 is molded from, for example, an insulating synthetic resin. The second fixing portion 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 an elastically deformable cylindrical member. The exterior member 30 is, for example, a member called a corrugated tube. The exterior member 30 is molded from, for example, 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 portion 10 and a second end 30b held by the second fixing portion 20. The first fixing portion 10 holds the first end 30a so that the exterior member 30 extends from the first fixing portion 10 along the rail 220 in the vehicle front-rear direction X. The first fixing portion 10 of the present embodiment holds the first end 30a so that the exterior member 30 extends from the first fixing portion 10 toward the front side X1.

[0022] The second fixing portion 20 holds the second end portion 30b so 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 so 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 through 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 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 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 curve in the vehicle longitudinal direction X between the first end 30a and the second end 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 slider 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 slider 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 at the fully open position is greater than the first distance L1 at 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. Furthermore, 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 smallest 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 slider 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.

[0030] 3, the cross-sectional shape of the exterior member 30 of this embodiment is rectangular. The illustrated biasing member 50 has a substantially flat plate shape. More specifically, the biasing member 50 has a flat plate-shaped main body 51 and ribs 52 protruding from the main body 51.

[0031] The cross section of the main body 51 perpendicular to the axial direction of the urging member 50 is rectangular. The main body 51 extends from one end to the other end in the width direction H in the internal space of the exterior member 30. The main body 51 faces each of the multiple electric wires W in the vehicle up-down direction Y. In other words, the main body 51 has a width that can support the multiple electric wires W.

[0032] The rib 52 protrudes from one of the main surfaces 51a of the main body 51 in a direction perpendicular to the main surface 51a. The illustrated rib 52 is disposed in the center of the main body 51 in the width direction H. The rib 52 is disposed, for example, on the outer main surface 51a. The outer main surface 51a is the surface of the curved portions 33, 34 that faces radially outward.

[0033] 3 is disposed on the inner side with respect to the electric wire W. Therefore, at the curved portions 33 and 34, the urging member 50 is located on the inner side in the radial direction with respect to the electric wire W. As shown in FIG. 3, the urging member 50 applies pressing forces F1 and F2 to the exterior member 30.

[0034] 4, the exterior member 30, the electric wire W, and the biasing member 50 are arranged in a U-shaped or J-shaped curve. That is, the biasing member 50 extends from the first fixed portion 10 to the second fixed portion 20 with a curved portion 54.

[0035] The biasing member 50 bent to have the curved portion 54 forms curved portions 33, 34 in the exterior member 30, and applies pressing forces F1 and F2 to the exterior member 30. The pressing force F1 is a force in the vehicle's up-down direction Y, and presses the exterior member 30 toward the rail 220. The pressing force F2 is a force in the vehicle's up-down direction Y, and presses the exterior member 30 toward the slider 210. The pressing forces F1 and F2 are restoring forces generated in the bent biasing member 50.

[0036] The pressing force F1 forms a first extension portion 31 in the exterior member 30. The pressing force F2 forms a second extension portion 32 in the exterior member 30. As shown in FIG. 2 and other figures, the second extension portion 32 is a portion that extends along the cabin-side surface 210a of the sliding body 210. The cabin-side surface 210a is a surface that faces the lower side Y2. When the cabin-side surface 210a is flat, the second extension portion 32 is formed in a linear shape. When the cabin-side surface 210a has a curved shape, the second extension portion 32 has a curved shape that follows the cabin-side surface 210a.

[0037] 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 enough rigidity to constantly press the exterior member 30 toward and keep it in contact with the sliding body 210. Therefore, the wiring structure 1 of this embodiment can stabilize the shape of the exterior member 30. The biasing member 50 can keep the exterior member 30 in contact with the sliding body 210 against external forces such as vibrations that occur during driving, for example.

[0038] As described below, the wiring structure 1 of this embodiment has a suppression portion 2 provided on the urging member 50. The suppression portion 2 improves the rigidity of the curved portion of the urging member 50 and suppresses the occurrence of a tapered shape in the curved portion.

[0039] 5 shows the tapered shape formed on the biasing member 150 of the comparative example. The biasing member 150 of the comparative example has a plate shape similar to the main body 51, and is not provided with the rib 52. 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.

[0040] The curved portion 151 has a tip portion 151a and two end portions 151b. The tip portion 151a is the center of the curved portion 151 and has a convex shape facing the vehicle longitudinal direction X. The end portions 151b are the ends of the curved portion 151 in the vehicle vertical 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 as it approaches the tip portion 151a from the end portions 151b.

[0041] 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. When the rigidity of the biasing member 150 is low, such a tapered shape is likely to be formed in the curved portion 151.

[0042] One possible way to prevent the occurrence of the tapered shape is to increase the thickness of the biasing member 150 to increase the rigidity of the biasing member 150. However, increasing the thickness of the biasing member 150 may result in a decrease in the durability of the biasing member 150 against bending.

[0043] In the wiring structure 1 of this embodiment, the ribs 52 shown in FIG. 3 ensure rigidity at the curved portion. The rigidity of the biasing member 50 provided with the ribs 52 is greater than the rigidity when the ribs 52 are not provided. In other words, the rigidity of the biasing member 50 having the ribs 52 is greater than the rigidity of the main body 51. Therefore, the tapered shape of the portion of the biasing member 50 that forms the curved portion is suppressed. The ribs 52 as the suppression portion 2 can improve the rigidity of the biasing member 50 at the curved portion, thereby suppressing the occurrence of a tapered shape of the biasing member 50 at the curved portion and suppressing the degree of the tapered shape.

[0044] In the biasing member 50 of this embodiment, the thickness of the main body 51 can be reduced by improving the rigidity with the ribs 52. Therefore, the biasing member 50 can ensure the necessary rigidity while suppressing a decrease in durability against bending.

[0045] The cross-sectional shape of the rib 52 illustrated in Fig. 3 is a tapered shape in which the dimension in the width direction H decreases with increasing distance from the main surface 51a. The cross-sectional shape of the rib 52 is, for example, approximately triangular. The cross-sectional shape of the top of the rib 52 may be curved. The cross-sectional shape of the bottom of the rib 52 may also be curved.

[0046] The rib 52 extends linearly along the axial direction of the biasing member 50. The rib 52 may be provided over the entire length of the biasing member 50, from one end to the other end of the biasing member 50. In this case, the tapered shape of the biasing member 50 is suppressed when the sliding body 210 is in the fully closed position, when the sliding body 210 is in the fully open position, and when the sliding body 210 is moving.

[0047] The position, number, and arrangement of the ribs 52 are not limited to those illustrated in Fig. 3. The ribs 52 may be arranged, for example, at the end of the biasing member 50 in the width direction H. The biasing member 50 may be provided with a plurality of ribs 52. The ribs 52 may be arranged on the main surface of the main body 51 opposite to the main surface 51a. The ribs 52 may be provided on each of the two main surfaces.

[0048] FIG. 6 shows another suppression portion 2 according to the embodiment. The suppression portion 2 in FIG. 6 is a tape member 3 wound around the urging member 50. The tape member 3 improves the rigidity of the portion of the urging member 50 around which the tape member 3 is wound. The tape member 3 is arranged, for example, at a position that forms the curved portions 33 and 34 of the urging member 50. FIG. 6 shows the tape member 3 arranged in a portion that forms the curved portion 33. In the following description, the portion of the urging member 50 that forms the curved portion 33 will be referred to as a first portion 53.

[0049] In the curved portion 33 formed when the sliding body 210 is in the fully closed position, the first portion 53 has a leading end 53a and two trailing end portions 53b. The leading end portion 53a is the central portion of the first portion 53 and has a convex shape facing the vehicle longitudinal direction X. The trailing end portions 53b are the ends of the first portion 53 in the vehicle vertical direction Y and are portions that connect to the straight portion portions 55, 56. The straight portion 55 is a portion that extends linearly along the rail 220. The straight portion 56 is a portion that extends linearly along the sliding body 210.

[0050] The tape member 3 is wound around the first portion 53 in a range including the tip portion 53a. The range in which the tape member 3 is provided around the urging member 50 includes a predetermined range from the tip portion 53a toward the straight portion 55 and a predetermined range from the tip portion 53a toward the straight portion 56. The winding range of the tape member 3 may be a symmetrical range with the tip portion 53a as the center. The tape member 3 may be wound around the urging member 50 in a spiral shape. The illustrated tape member 3 has exposed ends at the end portion 53b that connect to the straight portions 55, 56.

[0051] The angle α of the winding range of the tape member 3 with respect to the first portion 53 is, for example, an angle greater than 90°. The angle α may be 120°, 150°, or another angle.

[0052] The tape member 3 is deformable in response to the deformation of the urging member 50. The tape member 3 is configured to be, for example, stretchable. The tape member 3 improves the rigidity of the portion of the urging member 50 around which the tape member 3 is wound.

[0053] The tape member 3 improves the rigidity of the first portion 53 of the urging member 50 and can prevent the first portion 53 from tapering. The tape member 3 may be arranged in the portion of the urging member 50 that forms the curved portion 34. The portion that forms the curved portion 34 has a leading end and a trailing end similar to the leading end 53a and the trailing end 53b of the first portion 53. The tape member 3 is wrapped around a range that includes the leading end of the portion that forms the curved portion 34. The tape member 3 provided in the portion that forms the curved portion 34 can prevent the urging member 50 from tapering at the curved portion 34.

[0054] Fig. 7 shows another suppression unit 2 according to the embodiment. The suppression unit 2 in Fig. 7 is a tape member 4 that is wound around two separate locations around a portion of the urging member 50 that forms the curved portion. The tape member 4 is disposed on the first portion 53 of the urging member 50, for example.

[0055] The tape member 4 is wound around a range of the urging member 50 that includes the end portion 53b. The tape member 4 is wound, for example, spirally around the urging member 50. The two tape members 4 include a first tape member 4A and a second tape member 4B. The first tape member 4A is wound around the end portion 53b that connects to the straight portion 55. A portion of the first tape member 4A may be wound around the straight portion 55. The angle β of the winding range of the first tape member 4A with respect to the end portion 53b may be 30°, 45°, 60°, or any other angle.

[0056] The second tape member 4B is wound around the end portion 53b that connects to the straight portion 56. A portion of the second tape member 4B may be wound around the straight portion 56. The angle of the winding range of the second tape member 4B relative to the end portion 53b is, for example, the same as the angle β of the winding range of the first tape member 4A. In this way, the range in which the two tape members 4 are arranged excludes the tip portion 53a, which is the central portion of the first portion 53, and includes the two end portions 53b of the first portion 53.

[0057] As shown in FIG. 8 , when the urging member 50 forms the curved portion 33, the first tape member 4A generates a reaction force F3. The reaction force F3 has a component in the vehicle's up-down direction Y. The reaction force F3 pulls one end 53c of the tip portion 53a toward the rail 220. When the urging member 50 forms the curved portion 33, the second tape member 4B generates a reaction force F4. The reaction force F4 has a component in the vehicle's up-down direction Y and pulls the other end 53d of the tip portion 53a toward the slider 210. In other words, the reaction forces F3 and F4 are forces that pull the tip portion 53a in the vehicle's up-down direction Y and increase the bending radius of the tip portion 53a.

[0058] Therefore, the two tape members 4 can prevent the biasing member 50 from tapering at the curved portion 33. The two tape members 4 are wound around the biasing member 50 so that the tip portions 53a are exposed. That is, the rigidity of the tip portions 53a of the biasing member 50 is smaller than the rigidity of the portion around which the tape members 4 are wound. Therefore, the reaction forces F3 and F4 can effectively prevent the biasing member 50 from tapering at the curved portion 33.

[0059] The tape members 4 may be arranged at a position where the curved portion 34 of the urging member 50 is formed. The portion where the curved portion 34 is formed has a leading end and a trailing end similar to the leading end 53a and the trailing end 53b. The two tape members 4 are wrapped around the trailing end portions of the portion where the curved portion 34 is formed. The two tape members 4 are arranged so that the leading end portions of the portion where the curved portion 34 is formed are exposed.

[0060] Fig. 9 shows another suppression unit 2 according to the embodiment. The suppression unit 2 in Fig. 9 is a coating layer 5 formed on the biasing member 50. The coating layer 5 is formed of, for example, a resin coating. The coating layer 5 is deformable in response to the deformation of the biasing member 50. The coating layer 5 is, for example, an elastically deformable resin layer.

[0061] The coating layer 5 improves the rigidity of the portion of the biasing member 50 where the coating layer 5 is provided. The coating layer 5 is provided, for example, on the first portion 53 that forms the curved portion 33 of the biasing member 50. More specifically, the coating layer 5 is coated on a range of the first portion 53 that includes the tip portion 53a. The range of the biasing member 50 where the coating layer 5 is provided includes a predetermined range from the tip portion 53a toward the straight portion 55 and a predetermined range from the tip portion 53a toward the straight portion 56. The coating range may be symmetrical with the tip portion 53a as the center. The illustrated coating layer 5 has exposed ends that connect to the straight portions 55 and 56 at the end portion 53b.

[0062] The coating layer 5 is formed, for example, on a surface of the first portion 53 facing radially outward. The angle γ of the area where the coating layer 5 is formed relative to the first portion 53 is, for example, an angle greater than 90°. The angle γ may be 120°, 150°, or another angle.

[0063] The coating layer 5 improves the rigidity of the portion of the urging member 50 that forms the curved portion 33, and can prevent the urging member 50 from tapering at the curved portion 33. The coating layer 5 may be disposed on the portion of the urging member 50 that forms the curved portion 34. The portion that forms the curved portion 34 has a tip portion and a terminal portion similar to the tip portion 53a and the terminal portion 53b. The coating layer 5 is applied to a range that includes the tip portion of the portion that forms the curved portion 34. The coating layer 5 provided on the portion that forms the curved portion 34 can prevent the urging member 50 from tapering at the curved portion 34.

[0064] The coating layer 5 may be formed on the radially inner surface of the portion forming the curved portions 33, 34, or may be formed on both the radially outer and inner surfaces. The coating layer 5 may be coated in a cylindrical shape so as to surround the portion forming the curved portions 33, 34.

[0065] Fig. 10 shows another suppression unit 2 according to the embodiment. The suppression unit 2 in Fig. 10 is a coating layer 6 that is applied in two separate locations on a portion of the urging member 50 that forms the curved portion. The coating layer 6 is disposed, for example, at a position where the curved portion 33 of the urging member 50 is to be formed.

[0066] The coating layer 6 is applied to an area of ​​the biasing member 50 including the end portion 53b. The two coating layers 6 include a first coating layer 6A and a second coating layer 6B. The first coating layer 6A is formed on the end portion 53b that connects to the straight portion 55. A portion of the first coating layer 6A may be formed on the straight portion 55. The angle δ of the area where the first coating layer 6A is formed relative to the end portion 53b may be 30°, 45°, 60°, or any other angle.

[0067] The second coating layer 6B is formed on the end portion 53b that connects to the straight portion 56. A portion of the second coating layer 6B may be formed on the straight portion 56. The angle of the formation range of the second coating layer 6B relative to the end portion 53b is, for example, the same as the angle δ of the formation range of the first coating layer 6A.

[0068] The range in which the two coating layers 6 are arranged excludes the tip end 53a, which is the central portion of the first portion 53, and includes the two end ends 53b of the first portion 53. When the biasing member 50 forms the curved portion 33, the first coating layer 6A generates a reaction force F5. The reaction force F5 is a force that has a component in the vehicle's vertical direction Y. The reaction force F5 pulls one end 53c of the tip end 53a toward the rail 220.

[0069] When the biasing member 50 forms the curved portion 33, the second coating layer 6B generates a reaction force F6. The reaction force F6 has a component in the vehicle vertical direction Y, and pulls the other end 53d of the tip portion 53a toward the slide body 210. In other words, the reaction forces F5 and F6 are forces that pull the tip portion 53a in the vehicle vertical direction Y, and increase the bending radius of the tip portion 53a.

[0070] Therefore, the two coating layers 6 can prevent the biasing member 50 from tapering at the curved portion 33. The two coating layers 6 are wrapped around the biasing member 50 so as to expose the tip portion 53a. That is, the rigidity of the tip portion 53a of the biasing member 50 is smaller than the rigidity of the portion on which the coating layers 6 are formed. Therefore, the reaction forces F5 and F6 can effectively prevent the biasing member 50 from tapering at the curved portion 33.

[0071] As described above, the wiring structure 1 of this embodiment has the first fixing portion 10, the second fixing portion 20, the exterior member 30, the electric wire W, the plate-shaped biasing member 50, and the suppressing portion 2. The first fixing portion 10 is fixed to the body 110 of the vehicle 100. The second fixing portion 20 is fixed to a sliding body 210 that slides along the vehicle front-rear direction X relative to an opening 120a provided in a roof 120 of the body 110. The exterior member 30 has 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 through the exterior member 30.

[0072] The biasing member 50 forms a curved portion that curves in the vehicle longitudinal direction X between the first end 30a and the second end 30b of the exterior member 30. The suppressing portion 2 is provided in the biasing member 50 and improves the rigidity of the portion that forms the curved portion to suppress the tapering of the biasing member 50 at the curved portion. In the wiring structure 1 of this embodiment, the suppressing portion 2 can suppress the tapering of the biasing member 50 at the curved portion.

[0073] An example of the suppressing portion 2 is a rib 52 provided on the biasing member 50 and extending along the axial direction of the biasing member 50. The rib 52 can simultaneously reduce the thickness of the main body 51 of the biasing member 50 and improve the rigidity of the biasing member 50.

[0074] An example of the suppressing portion 2 is tape members 3 and 4 wound around the urging member 50. The tape members 3 and 4 improve the rigidity of the urging member 50 in the portions where the tape members 3 and 4 are provided, and can suppress the tapered shape.

[0075] An example of the suppression portion 2 is the coating layers 5, 6 formed on the biasing member 50. The coating layers 5, 6 improve the rigidity of the biasing member 50 in the portions where the coating layers 5, 6 are provided, and can suppress the tapered shape.

[0076] In this embodiment, the slider 210 moves between a fully closed position where the opening 120a is closed and a fully open position where the opening 120a is open. In the biasing member 50, the suppression unit 2 is disposed at a position where the curved portion 33 is formed when the slider 210 is in the fully closed position, or at a position where the curved portion 34 is formed when the slider 210 is in the fully open position, for example. The suppression unit 2 may be disposed at either the position where the curved portion 33 is formed or the position where the curved portion 34 is formed, or at both positions.

[0077] In the curved portion, the range in which the suppression portion 2 is arranged on the biasing member 50 is a range excluding the central portion of the portion that forms the curved portions 33, 34 and including the two end portions of the portion that forms the curved portions 33, 34. The suppression portion 2 arranged at the end portions can generate reaction forces F3, F4, F5, and F6 to suppress the tapered shape of the biasing member 50.

[0078] The exterior member 30 is not limited to a so-called corrugated tube. The exterior member 30 may be a braided tube or any other member used as an exterior member. The urging member 50 may be disposed on the outer side of the electric wire W. That is, the urging member 50 may be disposed on the radially outer side of the electric wire W at the curved portions 33, 34.

[0079] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
