[0062] [Implementation Method]

[0063] Reference Figures 1 to 10 , an embodiment is described. This embodiment relates to a wiring structure. Figure 1 and Figure 2 is a side view of a wiring structure according to an embodiment of the present invention, Figure 3 is a cross-sectional view of a wiring structure according to an embodiment of the present invention, Figure 4 is a side view of a wiring structure according to an embodiment of the present invention, Figure 5 This is a diagram to explain the tapered shape. Figures 6 to 10 It is a side view of the suppression part involved in embodiment. Figure 3 Show Figure 4 III-III section.

[0064] like Figure 1 As shown, the wiring structure 1 of the embodiment can be applied to a sunroof 200 of a vehicle 100. The vehicle 100 is, for example, a car 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 covering a vehicle interior. The roof 120 has an opening 120a that opens upward.

[0065] The vehicle 100 has a sunroof 200 for opening and closing an opening 120a. The sunroof 200 has a sliding body 210, a rail 220, and a wiring structure 1. The sliding body 210 is a component that slides relative to the opening 120a along the vehicle front-rear direction X. The sliding body 210 of this embodiment is a plate-shaped component that closes the opening 120a or opens the opening 120a. The sliding body 210 may also be a glass structured to allow light to pass through.

[0066] The sunroof 200 has a mechanism such as a link mechanism that moves the slide 210 along a predetermined path, and a driving source such as a motor that operates the mechanism. The sunroof 200 moves the slide 210 between a fully closed position that closes the opening 120a and a fully open position that opens the opening 120a. Figure 1 2 shows the sliding body 210 in the fully closed position. Figure 2 The slide body 210 is shown in the fully open position.

[0067] The rail 220 is fixed to the vehicle body 110 . The rail 220 extends in the vehicle front-rear direction X. The rail 220 supports a mechanism for moving the slider 210 and guides the mechanism in the vehicle front-rear direction X. The rail 220 also supports the exterior member 30 and forms a first extension portion 31 on the exterior member 30 .

[0068] The sunroof 200 of this embodiment allows the sliding body 210 to move along the Figure 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 in FIG. Figure 2 As indicated by the middle arrow AR1 , the slider 210 moves toward the upper side Y1 in the vehicle up-down direction Y, and moves toward the rear side X2 in the vehicle front-rear direction X.

[0069] In contrast, when the slider 210 moves from the fully open position toward the fully closed position, the slider 210 moves toward the front side X1 in the vehicle front-rear direction X and toward the lower side Y2 in the vehicle up-down direction Y.

[0070] like Figures 1 to 3 As shown, the wiring structure 1 includes a first fixing portion 10, a second fixing portion 20, an exterior member 30, electric wires W, and a biasing member 50. The exterior member 30 and the electric wires W constitute a wire harness routed between the vehicle body 110 and the slider 210.

[0071] The first fixing portion 10 is a member fixed to the vehicle body 110 of the vehicle 100. The first fixing portion 10 may also be a protector for protecting the electric wire W. The first fixing portion 10 is molded of, for example, an insulating synthetic resin. The first fixing portion 10 has a space for laying the electric wire W and has a holding structure for holding the exterior member 30.

[0072] The second fixing portion 20 is a component fixed to the sliding body 210 of the sunroof 200. The second fixing portion 20 may also be a protector for protecting the electric wire W. The second fixing portion 20 is molded of, for example, an insulating synthetic resin. The second fixing portion 20 has a space for laying the electric wire W and has a holding structure for holding the exterior member 30.

[0073] The exterior member 30 is an elastically deformable cylindrical member. The exterior member 30 is, for example, a member called a bellows. The exterior member 30 is molded from, for example, an insulating synthetic resin. The exterior member 30 may also have a bellows shape.

[0074] 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 first fixing portion 10 holds the first end portion 30a in a manner 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 portion 30a in a manner that the exterior member 30 extends from the first fixing portion 10 toward the front side X1.

[0075] 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 slider 210 in the vehicle longitudinal direction X. The second fixing portion 20 of this 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.

[0076] The outer member 30 has an electric wire W and a force-applying member 50 inserted therethrough. The electric wire W is, for example, a coated electric wire having a twisted wire and a coating layer. The electric wire W may be a flat wiring material, a printed circuit body, or other circuit bodies. The electric wire W led out from the first end 30a is connected to a power source or a control device disposed on the vehicle body 110. The electric wire W led out from the second end 30b is connected to a load disposed on the side of the sliding body 210. The load disposed on the sliding body 210 may be, for example, a lighting device, a dimming film disposed on the glass of the sliding body 210, or other electrical loads.

[0077] like Figure 1 and Figure 2 As shown, the exterior member 30 includes a curved portion 33 and a curved portion 34 that are curved in the vehicle front-rear direction X between the first end portion 30 a and the second end portion 30 b. The curved portion 33 and the curved portion 34 are formed by the urging member 50 . Figure 1 The curved portion 33 shown is a curved portion formed on the exterior member 30 when the slider 210 is in the fully closed position. The curved portion 33 has a radius R1. Figure 2 The curved portion 34 shown is a curved portion formed in the exterior member 30 when the slider 210 is in the fully open position. The curved portion 34 has a radius R2. The electric wire W formed with the curved portions 33 and 34 has a U-shape or a J-shape.

[0078] like Figure 1 As shown, when the slider 210 is in the fully closed position, the distance between the second end 30b and the first end 30a along the vehicle vertical direction Y is the first distance L1. The radius R1 of the curved portion 33 is half the first distance L1.

[0079] like Figure 2As shown, when the slider 210 is in the fully open position, the distance between the second end 30b and the first end 30a along the vehicle vertical direction Y is the second distance L2. The radius R2 of the curved portion 34 is half the second distance L2.

[0080] In the sunroof 200 of the present 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. In addition, the radius R1 when the sliding body 210 is in the fully closed position is smaller than the radius of the curved shape formed on the force applying member 50 when the sliding body 210 is in other positions. In other words, when the sliding body 210 is in the fully closed position, the radius of the curved shape formed on the force applying member 50 is minimized.

[0081] The second end portion 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.

[0082] The urging member 50 of the present embodiment is a member that presses the exterior member 30 toward the slider 210. The urging member 50 of the present embodiment is a plate-shaped member that is elastically deformable. The urging member 50 is formed of metal or resin.

[0083] like Figure 3 As shown, the cross-sectional shape of the exterior member 30 of the present embodiment is a rectangle. The shape of the urging member 50 of the example is a substantially flat plate shape. More specifically, the urging member 50 includes a flat plate-shaped main body 51 and ribs 52 protruding from the main body 51 .

[0084] In the main body 51, the cross-sectional shape of the force applying member 50 perpendicular to the axial direction is a rectangle. The main body 51 extends from one end to the other end in the internal space of the exterior member 30 in the width direction H. The main body 51 is opposed to the plurality of wires W in the vehicle vertical direction Y. In other words, the main body 51 has a width capable of supporting the plurality of wires W.

[0085] The rib 52 bulges from one main surface 51a of the main body 51 in a direction perpendicular to the main surface 51a. The rib 52 of the example is arranged at the center of the width direction H of the main body 51. The rib 52 is arranged, for example, on the outer main surface 51a. The outer main surface 51a is a surface facing radially outward in the curved portion 33 or the curved portion 34.

[0086] Figure 3 The force applying member 50 is arranged on the inner side relative to the wire W. Therefore, in the curved portion 33 and the curved portion 34, the force applying member 50 is located on the inner side relative to the wire W in the radial direction. Figure 3As shown, the urging member 50 applies pressing forces F1 and F2 to the exterior member 30 .

[0087] like Figure 4 As shown, the exterior member 30 , the electric wire W, and the urging member 50 are arranged in a state bent in a U-shape or a J-shape. That is, the urging member 50 extends from the first fixing portion 10 to the second fixing portion 20 with a bent portion 54 .

[0088] The force applying member 50 that is bent so as to have the bent portion 54 forms the bent portion 33 and the bent portion 34 on the exterior member 30, and applies a pressing force F1 and a pressing force F2 to the exterior member 30. The pressing force F1 is a force in the vehicle vertical direction Y, and presses the exterior member 30 toward the rail 220. The pressing force F2 is a force in the vehicle vertical direction Y, and presses the exterior member 30 toward the slider 210. The pressing forces F1 and F2 are restoring forces generated by the force applying member 50 after being bent.

[0089] The pressing force F1 forms a first extension portion 31 on the exterior member 30. The pressing force F2 forms a second extension portion 32 on the exterior member 30. Figure 2 As shown in the figure, the second extension portion 32 is a portion extending along the surface 210a on the vehicle compartment side of the sliding body 210. The surface 210a on the vehicle compartment side is a surface facing the lower side Y2. When the surface 210a on the vehicle compartment side is a plane, the second extension portion 32 is formed in a straight line. When the surface 210a on the vehicle compartment side has a curved shape, the second extension portion 32 has a curved shape along the surface 210a on the vehicle compartment side.

[0090] The force applying member 50 of the present embodiment is configured to press the outer 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 opened position. In other words, the force applying member 50 has a rigidity that enables the outer member 30 to always be pressed toward the sliding body 210 and in contact. Therefore, the wiring structure 1 of the present embodiment can stabilize the shape of the outer member 30. The force applying member 50 can make the outer member 30 contact the sliding body 210 by overcoming external forces such as vibration generated during driving, for example.

[0091] As described below, the wiring structure 1 of the present embodiment includes the suppression portion 2 provided in the urging member 50. The suppression portion 2 increases the rigidity of the bent portion of the urging member 50 and suppresses the occurrence of a tapered shape in the bent portion.

[0092] exist Figure 52 shows a tapered shape formed in the urging member 150 of the comparative example. The urging member 150 of the comparative example has the same plate shape as the main body 51, and is not provided with the rib 52. The urging member 150 is formed with a curved portion 151 and a straight portion 152. The straight portion 152 is a portion extending in a straight line, and is formed along the sliding body 210 and the rail 220, respectively.

[0093] The curved portion 151 has a front end portion 151a and two terminal portions 151b. The front end portion 151a is the central portion of the curved portion 151 and has a convex shape facing the vehicle front-rear direction X. The terminal portion 151b is the end of the curved portion 151 in the vehicle up-down direction Y and is a portion connected to the straight portion 152. The curved portion 151 has a tapered shape. More specifically, the shape of the curved portion 151 is a shape in which the bending radius decreases as it approaches the front end portion 151a from the terminal portion 151b.

[0094] exist Figure 5 , an imaginary circle IC is shown in FIG. The imaginary circle IC is a circle whose diameter is the distance L0 from the rail 220 to the slider 210 in the vehicle vertical direction Y. The bending radius of the front end portion 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 front end portion 151a is smaller than the bending radius of the terminal portion 151b. When the rigidity of the force-applying member 150 is small, such a tapered shape is easily formed in the curved portion 151.

[0095] As a means of suppressing the occurrence of the tapered shape, it is conceivable to increase the thickness of the urging member 150 to increase the rigidity of the urging member 150. On the other hand, if the thickness of the urging member 150 is increased, the durability of the urging member 150 against bending may be reduced.

[0096] In the wiring structure 1 of this embodiment, Figure 3 The rib 52 shown in the figure ensures the rigidity of the bent portion. The rigidity of the force applying member 50 provided with the rib 52 is greater than the rigidity of the case where the rib 52 is not provided. In other words, the rigidity of the force applying member 50 having the rib 52 is higher than the rigidity of the main body 51. Therefore, in the force applying member 50, the tapered shape of the portion forming the bent portion is suppressed. The rib 52 as the suppression portion 2 can improve the rigidity of the force applying member 50 at the bent portion and suppress the occurrence of the tapered shape of the force applying member 50 at the bent portion and suppress the degree of the tapered shape.

[0097] In the urging member 50 of the present embodiment, the thickness of the main body 51 can be reduced by improving the rigidity with the ribs 52. Therefore, it is possible to ensure the necessary rigidity while suppressing a decrease in the durability of the urging member 50 against bending.

[0098] Figure 3The cross-sectional shape of the rib 52 shown in the example is a tapered shape in which the dimension in the width direction H decreases as it moves away from the main surface 51a. The cross-sectional shape of the rib 52 is, for example, roughly triangular. The cross-sectional shape of the top of the rib 52 may be a curved shape. In addition, the cross-sectional shape of the hem of the rib 52 may also be a curved shape.

[0099] The rib 52 extends linearly along the axial direction of the urging member 50. The rib 52 may be provided over the entire length of the urging member 50 from one end to the other end of the urging member 50. In this case, the tapering shape of the urging member 50 is suppressed when the sliding body 210 is in the fully closed position, when the sliding body 210 is in the fully opened position, and when the sliding body 210 is moving.

[0100] In addition, the position of the ribs 52, the number of the ribs 52, and the arrangement of the ribs 52 are not limited to Figure 3 The positions, numbers and arrangements shown are exemplified. The rib 52 may be arranged, for example, at an end portion of the urging member 50 in the width direction H. A plurality of ribs 52 may be provided on the urging member 50. The rib 52 may be arranged on a main surface of the main body 51 on the opposite side to the main surface 51a. The rib 52 may be provided on both main surfaces.

[0101] exist Figure 6 2 shows another suppressing unit 2 of the embodiment. Figure 6 The restraining part 2 is a belt member 3 wound around the urging member 50. The belt member 3 increases the rigidity of the portion of the urging member 50 where the belt member 3 is wound. The belt member 3 is disposed, for example, at a position where the curved portion 33 and the curved portion 34 are formed in the urging member 50. Figure 6 2 shows the belt member 3 disposed at the portion where the curved portion 33 is formed. In the following description, the portion where the curved portion 33 is formed in the urging member 50 is referred to as a first portion 53.

[0102] In the curved portion 33 formed when the slider 210 is in the fully closed position, the first portion 53 has a front end portion 53a and two terminal portions 53b. The front end portion 53a is the central portion of the first portion 53 and has a convex shape facing the vehicle front-rear direction X. The terminal portion 53b is the end portion of the first portion 53 in the vehicle up-down direction Y and is connected to the straight portions 55 and 56. The straight portion 55 is a portion extending in a straight line along the rail 220. The straight portion 56 is a portion extending in a straight line along the slider 210.

[0103] The belt member 3 is wound around the range including the front end portion 53a in the first portion 53. The range in which the belt member 3 is provided to the force applying member 50 includes a predetermined range from the front end portion 53a toward the straight portion 55 and a predetermined range from the front end portion 53a toward the straight portion 56. The winding range of the belt member 3 may be a symmetrical range with the front end portion 53a as the center. The belt member 3 may be wound in a spiral shape with respect to the force applying member 50. The belt member 3 in the example exposes the end portion of the terminal portion 53b connected to the straight portions 55 and 56.

[0104] The angle α of the winding range of the belt member 3 with respect to the first portion 53 is, for example, an angle larger than 90°. The angle α may be 120°, 150°, or other angles.

[0105] The belt member 3 can be deformed following the deformation of the urging member 50. The belt member 3 is, for example, configured to be stretchable. The belt member 3 increases the rigidity of the portion of the urging member 50 around which the belt member 3 is wound.

[0106] The belt member 3 can improve the rigidity of the first portion 53 of the urging member 50 and suppress the tapered shape of the first portion 53. The belt member 3 can also be arranged in the portion of the urging member 50 where the curved portion 34 is formed. The portion where the curved portion 34 is formed has a front end portion and a terminal portion that are the same as the front end portion 53a and the terminal portion 53b of the first portion 53. The belt member 3 is wound around a range including the front end portion of the portion where the curved portion 34 is formed. The belt member 3 provided in the portion where the curved portion 34 is formed can suppress the tapered shape of the urging member 50 at the curved portion 34.

[0107] exist Figure 7 2 shows another suppressing unit 2 of the embodiment. Figure 7 The restraining portion 2 is a belt member 4 wound in two locations about a portion forming a curved portion in the urging member 50. The belt member 4 is disposed in the first portion 53 of the urging member 50, for example.

[0108] The belt component 4 is wound around a range including the terminal portion 53b in the force-applying component 50. The belt component 4 is, for example, wound in a spiral shape relative to the force-applying component 50. The two belt components 4 include a first belt component 4A and a second belt component 4B. The first belt component 4A is wound around the terminal portion 53b connected to the straight portion 55. A portion of the first belt component 4A may also be wound around the straight portion 55. An angle β of the winding range of the first belt component 4A relative to the terminal portion 53b may be 30°, 45°, 60°, or other angles.

[0109] The second belt member 4B is wound around the terminal portion 53b connected to the straight portion 56. A portion of the second belt member 4B may be wound around the straight portion 56. The angle of the winding range of the second belt member 4B relative to the terminal portion 53b is, for example, the same as the angle β of the winding range of the first belt member 4A. In this way, the range in which the two belt members 4 are arranged is the range including the two terminal portions 53b of the first portion 53, excluding the front end portion 53a as the central portion of the first portion 53.

[0110] like Figure 8 As shown, when the force applying member 50 forms the curved portion 33, the first belt member 4A generates a reaction force F3. The reaction force F3 is a force having a component in the vehicle vertical direction Y. The reaction force F3 pulls one end 53c of the front end portion 53a toward the rail 220. When the force applying member 50 forms the curved portion 33, the second belt member 4B generates a reaction force F4. The reaction force F4 is a force having a component in the vehicle vertical direction Y, and pulls the other end 53d of the front end portion 53a toward the sliding body 210. That is, the reaction force F3 and the reaction force F4 are forces that pull the front end portion 53a in the vehicle vertical direction Y, and are forces that increase the bending radius of the front end portion 53a.

[0111] Therefore, the two belt members 4 can suppress the tapered shape of the urging member 50 in the curved portion 33. The two belt members 4 are wound around the urging member 50 in such a manner that the front end portions 53a are exposed. That is, in the urging member 50, the rigidity of the front end portion 53a is lower than the rigidity of the portion around which the belt members 4 are wound. Therefore, the tapered shape of the urging member 50 in the curved portion 33 can be effectively suppressed by the reaction forces F3 and F4.

[0112] In addition, the belt member 4 may be arranged at a position where the curved portion 34 is formed in the urging member 50. The portion forming the curved portion 34 has a front end portion and a terminal portion similar to the front end portion 53a and the terminal portion 53b. The two belt members 4 are wound around the terminal portion of the portion forming the curved portion 34. The two belt members 4 are arranged so that the front end portion of the portion forming the curved portion 34 is exposed.

[0113] exist Fig. 9 2 shows another suppressing unit 2 of the embodiment. Fig. 9 The suppression portion 2 is a coating layer 5 formed on the urging member 50. The coating layer 5 is formed of, for example, a resin coating. The coating layer 5 can deform following the deformation of the urging member 50. The coating layer 5 is, for example, an elastically deformable resin layer.

[0114] The coating 5 improves the rigidity of the portion of the force-applying member 50 where the coating 5 is provided. The coating 5 is provided, for example, on the first portion 53 of the force-applying member 50 that forms the curved portion 33. More specifically, the coating 5 is applied to the range of the first portion 53 including the front end portion 53a. The range in which the coating 5 is provided on the force-applying member 50 includes a prescribed range from the front end portion 53a toward the straight portion 55, and a prescribed range from the front end portion 53a toward the straight portion 56. The coating range may also be a symmetrical range centered on the front end portion 53a. The exemplary coating 5 exposes the end portion of the terminal portion 53b connected to the straight portions 55 and 56.

[0115] The coating layer 5 is formed on the radially outward surface of the first portion 53, for example. The angle γ of the coating layer 5 to the first portion 53 is, for example, greater than 90°. The angle γ may be 120°, 150°, or other angles.

[0116] The coating 5 can improve the rigidity of the portion of the force applying member 50 that forms the curved portion 33, thereby suppressing the tapered shape of the force applying member 50 at the curved portion 33. The coating 5 can also be disposed on the portion of the force applying member 50 that forms the curved portion 34. The portion that forms the curved portion 34 has a front end portion and a terminal end portion that are the same as the front end portion 53a and the terminal end portion 53b. The coating 5 is applied to a range including the front end portion of the portion that forms the curved portion 34. The coating 5 disposed on the portion that forms the curved portion 34 can suppress the tapered shape of the force applying member 50 at the curved portion 34.

[0117] The coating layer 5 may be formed on the radially inner surface of the portion forming the curved portion 33 or 34, or may be formed on both the radially outer surface and the inner surface. The coating layer 5 may also be applied in a cylindrical shape so as to surround the portion forming the curved portion 33 or 34.

[0118] exist Fig.10 2 shows another suppressing unit 2 of the embodiment. Fig.10 The suppression portion 2 is a coating 6 applied to two portions of the portion forming the curved portion of the urging member 50. The coating 6 is disposed, for example, at a position in the urging member 50 where the curved portion 33 is formed.

[0119] The coating layer 6 is applied to the range including the terminal portion 53b of the force applying member 50. 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 terminal portion 53b connected to the straight portion 55. A portion of the first coating layer 6A may also be formed on the straight portion 55. The angle δ of the formation range of the first coating layer 6A relative to the terminal portion 53b may be 30°, 45°, 60°, or other angles.

[0120] The second coating layer 6B is formed at the terminal portion 53b connected to the straight portion 56. A part of the second coating layer 6B may be formed at the straight portion 56. The angle of the formation range of the second coating layer 6B with respect to the terminal portion 53b is, for example, the same as the angle δ of the formation range of the first coating layer 6A.

[0121] The range where the two coating layers 6 are arranged is a range excluding the front end portion 53a as the central portion of the first portion 53 and including the two terminal portions 53b of the first portion 53. When the force applying member 50 forms the curved portion 33, the first coating layer 6A generates a reaction force F5. The reaction force F5 is a force having a component in the vehicle up-down direction Y. The reaction force F5 pulls one end 53c of the front end portion 53a toward the rail 220.

[0122] When the force applying member 50 forms the curved portion 33, the second coating layer 6B generates a reaction force F6. The reaction force F6 is a force having a component in the vehicle vertical direction Y, and pulls the other end 53d of the front end portion 53a toward the sliding body 210. That is, the reaction force F5 and the reaction force F6 are forces that pull the front end portion 53a in the vehicle vertical direction Y, and are forces that increase the bending radius of the front end portion 53a.

[0123] Therefore, the two coatings 6 can suppress the tapered shape of the urging member 50 at the bent portion 33. The two coatings 6 are wound around the urging member 50 in such a manner that the front end portion 53a is exposed. That is, in the urging member 50, the rigidity of the front end portion 53a is lower than the rigidity of the portion formed with the coating 6. Therefore, the tapered shape of the urging member 50 at the bent portion 33 can be effectively suppressed by the reaction forces F5 and F6.

[0124] 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 plate-shaped force member 50, and the suppression portion 2. The first fixing portion 10 is fixed to the vehicle body 110 of the vehicle 100. The second fixing portion 20 is fixed to the sliding body 210, and the sliding body 210 slides along the vehicle front-rear direction X relative to the opening portion 120a provided in the roof 120 of the vehicle body 110. The exterior member 30 includes the first end portion 30a held by the first fixing portion 10 and the second end portion 30b held by the second fixing portion 20. The electric wire W and the force member 50 are inserted through the exterior member 30.

[0125] The urging member 50 forms a curved portion between the first end portion 30a and the second end portion 30b of the exterior member 30, which is curved toward the vehicle front-rear direction X. The suppressing portion 2 is provided on the urging member 50, and the rigidity of the portion forming the curved portion is increased to suppress the tapered shape of the urging member 50 at the curved portion. In the wiring structure 1 of the present embodiment, the tapered shape of the urging member 50 at the curved portion can be suppressed by the suppressing portion 2.

[0126] An example of the suppressing portion 2 is a rib 52 provided on the urging member 50 and extending in the axial direction of the urging member 50. The rib 52 can achieve both a reduction in thickness of the main body 51 of the urging member 50 and an improvement in the rigidity of the urging member 50.

[0127] An example of the suppressing portion 2 is the belt members 3 and 4 wound around the urging member 50. The belt members 3 and 4 can increase the rigidity of the portion of the urging member 50 where the belt members 3 and 4 are provided, thereby suppressing the tapered shape.

[0128] An example of the suppression portion 2 is the coating layers 5 and 6 formed on the urging member 50. The coating layers 5 and 6 can improve the rigidity of the portion of the urging member 50 where the coating layers 5 and 6 are provided, thereby suppressing the tapered shape.

[0129] The slider 210 of this embodiment moves between a fully closed position in which the opening 120a is closed and a fully open position in which the opening 120a is opened. In the force-applying member 50, the position where the suppressing portion 2 is arranged is, for example, a position where the curved portion 33 is formed when the slider 210 is in the fully closed position, or a position where the curved portion 34 is formed when the slider 210 is in the fully open position. The suppressing portion 2 may be arranged at either the position in which the curved portion 33 is formed or the position in which the curved portion 34 is formed, or may be arranged at both positions.

[0130] In the curved portion, the range in which the suppression portion 2 is arranged in the urging member 50 is a range excluding the central portion of the portion forming the curved portion 33 and the curved portion 34 and including the two terminal portions of the portion forming the curved portion 33 and the curved portion 34. The suppression portion 2 arranged at the terminal portion can generate reaction forces F3, F4, F5, and F6 to suppress the tapered shape in the urging member 50.

[0131] In addition, the outer component 30 is not limited to the so-called corrugated tube. The outer component 30 may be a braided tube or a component used as another outer component. The force applying component 50 may also be arranged outside the wire W. That is, the force applying component 50 may also be arranged outside the wire W in the radial direction in the curved portion 33 and the curved portion 34.

[0132] The contents disclosed in the above-mentioned embodiments can be executed in combination as appropriate.
