[0043] [Implementation Method]

Figure 3 Show Figure 4 III-III section.

[0045] like Figure 1 As shown, the wiring structure 1 of the embodiment is 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.

[0046] 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.

[0047] 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.

[0048] The rail 220 is fixed to the vehicle body 110. The rail 220 is disposed on the lower side Y2 relative to the slider 210 and extends in the vehicle front-rear direction X. The rail 220 supports a mechanism that moves 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] The first fixing portion 10 is a component fixed to the vehicle body 110 of the vehicle 100. The first fixing portion 10 of the present embodiment is fixed to the rail 220. The first fixing portion 10 may also be a protector for protecting the electric wire W. The first fixing portion 10 is molded, for example, from 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 component 30.

[0053] 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 component 30.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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 of a glass disposed on the sliding body 210, or other electrical loads.

[0058] like Figure 1 and Figure 2 As shown, the exterior member 30 has curved portions 33 and 34 curved in the vehicle front-rear direction X between the first end portion 30 a and the second end portion 30 b . The curved portions 33 and 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 2The curved portion 34 shown is a curved portion formed on 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.

[0059] 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.

[0060] like Figure 2 As 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 size of the second distance L2.

[0061] 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 the smallest.

[0062] 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.

[0063] The urging member 50 of this embodiment is a member that presses the exterior member 30 toward the slider 210. The urging member 50 of this embodiment is a plate-shaped member that can be elastically deformed. The urging member 50 is formed of metal or resin. The urging member 50 extends from the first end 30a of the exterior member 30 to the second end 30b.

[0064] 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 force member 50 of the example is a substantially flat plate shape. In the force member 50, the cross-sectional shape perpendicular to the axial direction of the force member 50 is a rectangle. The force 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 force member 50 is respectively opposed to the plurality of wires W in the vehicle vertical direction Y. In other words, the force member 50 has a width capable of supporting the plurality of wires W.

[0065] Figure 3 The force applying member 50 is arranged outside the wire W. Therefore, in the curved portions 33 and 34, the force applying member 50 is located outside the wire W in the radial direction. Figure 3 As shown, the urging member 50 is in contact with the exterior member 30 , and applies pressing forces F1 and F2 to the exterior member 30 at the contact surface.

[0066] 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 .

[0067] The force applying member 50 bent to have the curved portion 54 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 bent force applying member 50.

[0068] 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 FIGS. 1 and 1 , the second extension portion 32 is a portion extending along the vehicle cabin side surface 210 a of the slider 210. The vehicle cabin side surface 210 a is a surface facing the lower side Y2.

[0069] 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 can always press the outer member 30 toward the sliding body 210 so that the outer member 30 and the sliding body 210 are 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, for example, overcome external forces such as vibration generated during driving and make the outer member 30 and the sliding body 210 contact.

[0070] As described below, the wiring structure 1 of the present embodiment is configured to suppress the tapered shape in the urging member 50. First, the tapered shape formed in the urging member will be described.

[0071] exist Figure 5 2 shows the tapered shape of the urging member 150 formed in the comparative example. The urging member 150 of the comparative example has the same plate shape as the urging member 50 of the embodiment. 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.

[0072] 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 toward the vehicle front-rear direction X. The terminal portion 151b is the end portion 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 radius of curvature decreases as it approaches the front end portion 151a from the terminal portion 151b.

[0073] exist Figure 5 , an imaginary circle IC is shown. 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 radius of curvature 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 radius of curvature of the front end portion 151a is smaller than the radius of curvature of the terminal end portion 151b.

[0074] The reason why the curved portion 151 is formed into a tapered shape is considered to be the reaction force acting on the distal end portion 151b. Figure 5 In the force applying member 150 shown, the straight portion 152 is supported by the sliding body 210 and the rail 220. In this case, the end portion 151b becomes a portion whose shape gradually changes from a straight line shape to an arc shape. In the following description, the range in which the shape of the force applying member 50, 150 gradually changes from a straight line shape to an arc shape is simply referred to as a "gradual change range".

[0075] like Figure 5 As shown by the middle arrow AR3, a force in the vehicle vertical direction Y that tends to approach a straight line shape acts on the terminal portion 151b. Due to this force, the radius of curvature of the terminal portion 151b tends to be larger than the radius of the imaginary circle IC. As a result, it is considered that a tapered shape is formed in which the radius of curvature of the front end portion 151a is smaller than the radius of the imaginary circle IC.

[0076] exist Figure 6 The bent portion 54 formed in the urging member 50 of this embodiment is shown in FIG. Figure 6 In the figure, 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 the present embodiment includes a first arc portion 55 and a second arc portion 56.

[0077] The first arc portion 55 is formed in a portion of the curved portion 54 along the rail 220. The first arc portion 55 has an arc shape that is convex toward the lower side Y2 in the vehicle vertical direction Y. That is, the first arc portion 55 faces the rail 220 and curves toward the rail 220. The first arc portion 55 has a vertex 55a as the lower end of the curved portion 54.

[0078] The first arc portion 55 has inclined portions 55b and 55c on both sides of the front side X1 and the rear side X2 relative to the vertex 55a. The first inclined portion 55b is located at the front side X1 relative to the vertex 55a. The second inclined portion 55c is located at the rear side X2 relative to the vertex 55a. The first inclined portion 55b and the second inclined portion 55c are inclined in a manner of being away from the vertex 55a and toward the upper side Y1. That is, the two inclined portions 55b and 55c are respectively inclined relative to the rail 220, and are away from the rail 220 as they are away from the vertex 55a. The first inclined portion 55b and the second inclined portion 55c each have an arc shape.

[0079] The urging member 50 includes a first extending portion 51 extending linearly from the first arc portion 55 toward the first fixing portion 10. A boundary 55d between the first arc portion 55 and the first extending portion 51 is located at the rear side X2 relative to the apex 55a.

[0080] By forming the second inclined portion 55c in the urging member 50, the gradual change range is shifted to the first extension portion 51 side. In other words, the gradual change range includes a portion of the urging member 50 that is closer to the rear side X2 than the vertex 55a. As a result, the radius of curvature of the first inclined portion 55b becomes close to the radius of the imaginary circle IC determined by the distance L0, and the tapering shape of the curved portion 54 is suppressed.

[0081] The second arc portion 56 is formed in a portion of the curved portion 54 along the slider 210. The second arc portion 56 has an arc shape that is convex toward the upper side Y1 in the vehicle vertical direction Y. That is, the second arc portion 56 faces the surface 210a on the vehicle cabin side of the slider 210 and curves toward the surface 210a on the vehicle cabin side. The second arc portion 56 has a vertex 56a as the upper end of the curved portion 54.

[0082] The second arc portion 56 has inclined portions 56b and 56c on both sides of the front side X1 and the rear side X2 relative to the vertex 56a. The first inclined portion 56b is located at the front side X1 relative to the vertex 56a. The second inclined portion 56c is located at the rear side X2 relative to the vertex 56a. The first inclined portion 56b and the second inclined portion 56c are inclined in a manner of being moved away from the vertex 56a toward the lower side Y2. That is, the two inclined portions 56b and 56c are respectively inclined relative to the surface 210a on the vehicle compartment side, and are moved away from the surface 210a on the vehicle compartment side as they move away from the vertex 56a. The first inclined portion 56b and the second inclined portion 56c each have an arc shape.

[0083] The urging member 50 includes a second extending portion 52 extending linearly from the second arc portion 56 toward the second fixing portion 20. A boundary 56d between the second arc portion 56 and the second extending portion 52 is located at the rear side X2 relative to the apex 56a.

[0084] By forming the second inclined portion 56c in the urging member 50, the gradual change range is shifted to the second extension portion 52 side. In other words, the gradual change range includes a portion of the urging member 50 that is closer to the rear side X2 than the vertex 56a. As a result, the radius of curvature of the first inclined portion 56b becomes close to the radius of the imaginary circle IC determined by the distance L0, and the tapering shape of the curved portion 54 is suppressed.

[0085] The wiring structure 1 of the present embodiment includes the support structure 4 forming the first arc portion 55 and the second arc portion 56. The support structure 4 of the present embodiment includes both the first support structure 41 and the second support structure 42 described below.

[0086] As reference Figure 7 As described above, the first arc portion 55 is formed by the first support structure 41. The first support structure 41 of the example is provided on the first fixing portion 10. The first support structure 41 has a support surface 11. The support surface 11 is a surface of the first fixing portion 10, and faces the upper side Y1 in the vehicle vertical direction Y. The support surface 11 is separated from the rail 220 and is located on the upper side Y1 relative to the rail 220.

[0087] The support surface 11 supports the first end 50a of the force-applying 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 also be fixed to the support surface 11 by a fixing member 12. The fixing member 12 may be an adhesive tape or a belt member such as a binding tape. The support surface 11 supports the first end 50a at a position away from the rail 220. Thus, a first arc portion 55 and a first extension portion 51 are formed in the force-applying member 50. The relative position of the support surface 11 with respect to the rail 220 is determined so that the first arc portion 55 of an appropriate shape can be formed.

[0088] Figure 7 The urging member 50 is shown when the slider 210 is in the fully open position. In this case, the curved portion 54 of the urging member 50 forms the curved portion 34 in the fully open position of the exterior member 30. By suppressing the tapered shape of the curved portion 54 in the fully open position, the bending durability of the wire W is suppressed from being reduced.

[0089] As reference Figure 8 As described above, the second arc portion 56 is formed by the second supporting structure 42. The second supporting structure 42 of the example is provided on the second fixing portion 20. The second supporting structure 42 has a supporting surface 21 and a clamping portion 22. The supporting surface 21 is a surface of the second fixing portion 20, and faces the lower side Y2 in the vehicle vertical direction Y. The supporting surface 21 is separated from the sliding body 210 and is located at the lower side Y2 relative to the sliding body 210. The supporting surface 21 is an inclined surface inclined with respect to the vehicle front-rear direction X. The supporting surface 21 is inclined in a manner that moves away from the sliding body 210 as it moves toward the rear side X2 in the vehicle front-rear direction X.

[0090] The support surface 21 supports the second end portion 50b of the force application member 50. The second end portion 50b is an end portion corresponding to the second end portion 30b of the exterior member 30. A portion of the second end portion 50b is clamped by the clamping portion 22. The clamping portion 22 clamps the second end portion 50b from both sides in the vehicle vertical direction Y to hold the second end portion 50b. The clamping portion 22 clamps, for example, a portion on the rear side X2 of the second end portion 50b.

[0091] The support surface 21 supports the second end portion 50b at a position away from the slider 210. Thus, the second arc portion 56 and the second extension portion 52 are formed in the urging member 50. The relative position of the support surface 21 to the slider 210 is determined so that the second arc portion 56 of an appropriate shape can be formed.

[0092] Figure 8 The urging member 50 is shown when the slider 210 is in the fully closed position. In this case, the curved portion 54 of the urging member 50 forms the curved portion 33 in the fully closed position on the exterior member 30. In the fully closed position, the interval between the rail 220 and the slider 210 in the vehicle vertical direction Y is the narrowest. By suppressing the tapered shape of the curved portion 54 in the fully closed position, the reduction in the bending durability of the wire W is suppressed.

[0093] The support surface 21 can restrict the inclination angle of the second extension portion 52. In addition, 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 that can absorb vibration.

[0094] like Figure 7 As shown, the wiring structure 1 of this embodiment is configured such that the curved portion 54 forms both the first arc portion 55 and the second arc portion 56 when the slider 210 is in the fully open position. The second support structure 42 is configured to form the second arc portion 56 when the slider 210 is in the fully open position. Figure 8 The position of the clamping portion 22 shown is determined so as to form the second arc portion 56 in the fully open position.

[0095] When the sliding body 210 moves, the force applying member 50 may also Fig. 9 For example, when the slider 210 moves toward the rear side X2 from the fully closed position toward the fully open position, the curved portion 54 of the force applying member 50 is separated from the second fixing portion 20. At this time, the second end portion 50b of the force applying member 50 may also be separated from the supporting surface 21. The clamping portion 22 holds the second end portion 50b at a position away from the slider 210, and the second arc portion 56 can be formed at the curved portion 54.

[0096] like Figure 8As shown, the wiring structure 1 of this embodiment is configured such that the curved portion 54 forms both the first arc portion 55 and the second arc portion 56 when the sliding body 210 is in the fully closed position. The first supporting structure 41 is configured such that the first arc portion 55 can be formed when the sliding body 210 is in the fully closed position. Figure 7 The position of the support surface 11 shown is determined so as to form the first arc portion 55 in the fully closed position.

[0097] The support structure 4 may also 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 implemented by the first support structure 41 and the second support structure 42 as described above. For example, the second support structure 42 configured 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 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.

[0098] In addition, the support surface 11 of the first support structure 41 may be an inclined surface inclined relative to the rail 220. In this case, the support surface 11 is inclined so as to be 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 may not be inclined relative to the slider 210.

[0099] The first supporting structure 41 may also be a component different from the first fixing portion 10. For example, a first supporting component having a supporting surface 11 may be provided adjacent to the first fixing portion 10. The first supporting component may also include a fixing component 12. The second supporting structure 42 may also be a component different from the second fixing portion 20. For example, a second supporting component having a supporting surface 21 may be provided adjacent to the second fixing portion 20. The second supporting component may also include a clamping portion 22.

[0100] The support structure 4 may include only one of the first support structure 41 and the second support structure 42. For example, the support structure 4 may include the first support structure 41 and not include the second support structure 42. In this case, the second extension portion 52 may extend while contacting the sliding body 210. For example, the support structure 4 may include the second support structure 42 and not include the first support structure 41.

[0101] 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 force applying member 50, and the support structure 4. The first fixing portion 10 is fixed to the rail 220. The rail 220 is arranged 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 sliding body 210. The sliding body 210 extends in 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 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 force applying member 50 are inserted through the exterior member 30.

[0102] The force applying member 50 has a curved portion 54 curved toward the vehicle front-rear direction X at a position between the first end portion 30a and the second end portion 30b. The support structure 4 supports the force applying 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 at the curved portion 54. The second support structure 42 forms a second arc portion 56 at the curved portion 54.

[0103] The first arc portion 55 is formed at a portion of the curved portion 54 along the rail 220 and has an arc shape that is convex toward the lower side Y2 in the vehicle vertical direction Y. The second arc portion 56 is formed at a portion of the curved portion 54 along the slider 210 and has an arc shape that is convex toward the upper side Y1 in the vehicle vertical direction Y. The wiring structure 1 of the present embodiment forms at least one of the first arc portion 55 and the second arc portion 56 at the curved portion 54 of the urging member 50, thereby suppressing the tapered shape of the curved portion 54 of the urging member 50.

[0104] The first arc portion 55 of the present embodiment has a vertex 55a as 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 so as to be away from the vertex 55a toward the upper side Y1 in the vehicle vertical direction Y. The first arc portion 55 having such a shape can suppress the tapering shape of the curved portion 54.

[0105] The second arc portion 56 of the present embodiment has a vertex 56a as 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 front-rear direction X. The pair of inclined portions 56b, 56c are inclined so as to be away from the vertex 56a toward the lower side Y2 in the vehicle vertical direction Y. The second arc portion 56 having such a shape can suppress the tapering shape of the curved portion 54.

[0106] 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. The support structure 4 includes a first support structure 41 and a second support structure 42. The first support structure 41 is configured to form a first arc portion 55 when the slider 210 is in any position from the fully closed position to the fully open position. The second support structure 42 is configured to form a second arc portion 56 when the slider 210 is in any position from the fully closed position to the fully open position. By always forming the first arc portion 55 and the second arc portion 56, the tapering shape of the curved portion 54 can be appropriately suppressed.

[0107] The arrangement and structure of the first support structure 41 and the second support structure 42 are not limited to those 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 another member used as an exterior member.

[0108] The urging member 50 may be arranged inside the wire W. That is, the urging member 50 may be arranged inside the wire W in the radial direction in the curved portions 33 and 34. The urging member 50 is not limited to a plate-shaped member. The urging member 50 may be a round rod with a circular cross-sectional shape or a rod-shaped member with a polygonal cross-sectional shape.

[0109] The contents disclosed in the above-mentioned embodiments can be executed in combination as appropriate.
