[0013] As shown in Fig. 1, a wiring structure 1 of the embodiment is applied to a sunroof 200 of a vehicle 100. The vehicle 100 is, for example, an automobile equipped with a power source such as a motor or an engine. The vehicle 100 has a vehicle body 110. The vehicle body 110 has a roof 120 that covers the passenger compartment. The roof 120 has an opening 120a that opens upward.

[0014] The vehicle 100 has a sunroof 200 that opens and closes the opening 120a. The sunroof 200 has a sliding body 210, a rail 220, and a wiring structure 1. The sliding body 210 is a member that slides along the vehicle front-rear direction X with respect to the opening 120a. The sliding body 210 of this embodiment is a plate-like member that closes or opens the opening 120a. The sliding body 210 may be glass that is configured to be able to transmit light.

[0015] The sunroof 200 has a mechanism such as a link mechanism that moves the sliding body 210 along a predetermined path, and a drive source such as a motor that operates the mechanism. The sunroof 200 moves the sliding body 210 between a fully closed position where the opening 120a is closed and a fully open position where the opening 120a is opened. Figure 1 shows the sliding body 210 in the fully closed position. Figure 2 shows the sliding body 210 in the fully open position.

[0016] 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 that moves the slide body 210, and guides this mechanism in the vehicle front-rear direction X. The rail 220 further supports the exterior member 30 to form a first extension portion 31 in the exterior member 30.

[0017] The sunroof 200 of this embodiment moves the sliding body 210 along a path AR0 shown in Fig. 2. The movement of the sliding body 210 along the path AR0 includes movement along the vehicle front-rear direction X and movement along the vehicle up-down direction Y. When the sliding body 210 moves from the fully closed position to the fully open position, as shown by the arrow AR1 in Fig. 2, the sliding body 210 moves toward the upper side Y1 in the vehicle up-down direction Y and toward the rear side X2 in the vehicle front-rear direction X.

[0018] Conversely, when the slide body 210 moves from the fully open position to the fully closed position, the slide body 210 moves toward the front side X1 in the vehicle longitudinal direction X and moves toward the lower side Y2 in the vehicle vertical direction Y.

[0019] 1 to 3, the wiring structure 1 has a first fixing portion 10, a second fixing portion 20, an exterior member 30, an electric wire W, and a biasing member 50. The exterior member 30 and the electric wire W configure a wire harness that is wired between the vehicle body 110 and the slide body 210.

[0020] The first fixing part 10 is a member fixed to the vehicle 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, for example, from 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.

[0021] The second fixing part 20 is a member fixed to the sliding body 210 of the sunroof 200. The second fixing part 20 may be a protector that protects the electric wires W. The second fixing part 20 is molded, for example, from an insulating synthetic resin. The second fixing part 20 has a space in which the electric wires W are routed, and has a holding structure that holds the exterior member 30.

[0022] The exterior member 30 is a cylindrical member that is elastically deformable. The exterior member 30 is, for example, a member called a corrugated tube. The exterior member 30 is molded, for example, from an insulating synthetic resin. The exterior member 30 may have a bellows shape.

[0023] The exterior member 30 has a first end 30a held by the first fixing part 10 and a second end 30b held by the second fixing part 20. The first fixing part 10 holds the first end 30a such that the exterior member 30 extends from the first fixing part 10 along the rail 220 in the vehicle front-rear direction X. The first fixing part 10 of the present embodiment holds the first end 30a such that the exterior member 30 extends from the first fixing part 10 toward the front side X1.

[0024] The second fixing portion 20 holds the second end portion 30b such that the exterior member 30 extends from the second fixing portion 20 along the slide body 210 in the vehicle front-rear direction X. The second fixing portion 20 of the present embodiment holds the second end portion 30b such that the exterior member 30 extends from the second fixing portion 20 toward the front side X1.

[0025] An electric wire W and a biasing member 50 are inserted into the exterior member 30. The electric wire W is, for example, a coated electric wire having a twisted wire and a coating. The electric wire W may be a flat wiring material, a printed circuit body, or other circuit body. The electric wire W drawn out from the first end portion 30a is connected to a power source or a control device arranged in the vehicle body 110. The electric wire W drawn out from the second end portion 30b is connected to a load arranged on the side of the sliding body 210. The load arranged on the sliding body 210 may be, for example, a lighting device, a light control film arranged on the glass of the sliding body 210, or other electric load.

[0026] As shown in Figs. 1 and 2, the exterior member 30 has curved portions 33, 34 that are curved in the vehicle front-rear direction X between the first end portion 30a and the second end portion 30b. The curved portions 33, 34 are formed by a biasing member 50. The curved portion 33 shown in Fig. 1 is a curved portion formed in the exterior member 30 when the sliding body 210 is in the fully closed position. The curved portion 33 has a radius R1. The curved portion 34 shown in Fig. 2 is a curved portion formed in the exterior member 30 when the sliding body 210 is in the fully open position. The curved portion 34 has a radius R2. The electric wire W on which the curved portions 33, 34 are formed has a U-shape or a J-shape.

[0027] 1, when the sliding body 210 is in the fully closed position, the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y is a first distance L1. The radius R1 of the curved portion 33 is half the first distance L1.

[0028] 2, when the sliding body 210 is in the fully open position, the distance between the first end 30a and the second end 30b in the vehicle vertical direction Y is a second distance L2. The radius R2 of the curved portion 34 is half the second distance L2.

[0029] In the sunroof 200 of this embodiment, the second distance L2 in the fully open position is greater than the first distance L1 in the fully closed position. Therefore, the radius R1 of the curved portion 33 when the sliding body 210 is in the fully closed position is smaller than the radius R2 of the curved portion 34 when the sliding body 210 is in the fully open position. Also, the radius R1 when the sliding body 210 is in the fully closed position is smaller than the radius of the curved shape formed in the biasing member 50 when the sliding body 210 is in another position. In other words, the magnitude of the radius of the curved shape formed in the biasing member 50 is minimum when the sliding body 210 is in the fully closed position.

[0030] 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 fixed portion 20 while gradually changing the position where the curved shape is formed.

[0031] The biasing member 50 of the present embodiment is a member that presses the exterior member 30 toward the sliding body 210. The biasing member 50 of the present embodiment is a plate-shaped member that is elastically deformable. The biasing member 50 is made of metal or resin.

[0032] As shown in Fig. 3, the cross-sectional shape of the exterior member 30 of this embodiment is rectangular. The shape of the urging member 50 illustrated is a flat plate shape. In the urging member 50, the cross-sectional shape perpendicular to the axial direction of the urging member 50 is rectangular. The urging member 50 extends from one end to the other end in the width direction H in the internal space of the exterior member 30. The urging member 50 faces each of the multiple electric wires W in the vehicle up-down direction Y. In other words, the urging member 50 has a width capable of supporting the multiple electric wires W.

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

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

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

[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 etc., 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 facing the lower side Y2. When the cabin side surface 210a is a flat surface, the second extension portion 32 is formed in a straight line. 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 a rigidity that can constantly press the exterior member 30 toward the sliding body 210 and keep it in contact with it. Therefore, the wiring structure 1 of this embodiment can stabilize the shape of the exterior member 30. For example, the biasing member 50 can keep the exterior member 30 in contact with the sliding body 210 against an external force such as vibration generated during driving.

[0038] As described below, the wiring structure 1 of this embodiment is configured so that the electric wire W has a slack retaining portion Ws inside the exterior member 30. Fig. 5 shows the electric wire W and the biasing member 50 before being inserted into the exterior member 30. The biasing member 50 before being inserted into the exterior member 30 has a flat plate shape. The electric wire W is held by the holding portion 2 so as to have the slack retaining portion Ws. The holding portion 2 in Fig. 5 holds the electric wire W by fixing the electric wire W to the biasing member 50. The holding portion 2 holds the electric wire W by fixing at least two points of the electric wire W to the biasing member 50.

[0039] The holding portion 2 is a member capable of fixing the electric wire W to the biasing member 50, such as, for example, an adhesive tape or a cable tie. The two holding portions 2 in FIG. 5 fix the electric wire W to both ends of the biasing member 50. The length of the slack holding portion Ws of the electric wire W is longer than the length L1 between the two holding portions 2 in the biasing member 50. Therefore, the slack holding portion Ws can extend while curving along the biasing member 50 between the two holding portions 2. The slack holding portion Ws of this embodiment is a portion having slack with respect to the exterior member 30 and the biasing member 50. In other words, the slack holding portion Ws is a meandering portion having a length sufficient to meander inside the exterior member 30.

[0040] The urging member 50 and the electric wire W fixed to the urging member 50 are inserted into the exterior member 30. The exterior member 30 and the urging member 50 are held by the first fixing portion 10 and the second fixing portion 20. As a result, a curved portion 54 is formed in the urging member 50, and a curved shape corresponding to the curved portion 54 is formed in the exterior member 30.

[0041] 6 shows the electric wire W located at the curved portion 35 of the exterior member 30. The curved portion 35 is a curved portion formed by the curved portion 54 of the biasing member 50. The curved portion 35 may be the curved portion 33 when the sliding body 210 is in the fully closed position, may be the curved portion 34 when the sliding body 210 is in the fully open position, or may be a curved portion when the sliding body 210 is in another position.

[0042] Since the electric wire W has the slack retaining portion Ws inside the exterior member 30, excessive stress is unlikely to be generated in the electric wire W at the curved portion 35. The electric wire W having the slack retaining portion Ws extends while being curved inside the exterior member 30. In this case, the electric wire W forms, for example, a serpentine shape inside the exterior member 30. The electric wire shown in FIG. 6 forms a serpentine portion Wa that meanders along the support surface of the biasing member 50 inside the exterior member 30. When the exterior member 30 forms the curved portion 35, bending and twisting deformation are generated in the electric wire W having the slack retaining portion Ws.

[0043] As a comparative example, when the electric wire W does not have the slack retaining portion Ws, bending deformation mainly occurs in the electric wire W corresponding to the curved portion 35 when the exterior member 30 is deformed. In contrast, in the electric wire W of this embodiment having the slack retaining portion Ws, not only bending but also torsional deformation occurs. This relieves the stress generated in the electric wire W when following the deformation of the exterior member 30, and improves the durability of the electric wire W against bending. In addition, when the electric wire W has the slack retaining portion Ws, excessive pulling force is unlikely to act on the electric wire W when the curved portion 35 is formed. Therefore, the durability of the electric wire W is improved.

[0044] 7 to 10, a method for routing the electric wire W to the urging member 50 will be described. FIG. 7 shows an electric wire assembly 60 manufactured in a jig 300. The electric wire assembly 60 has the urging member 50, an electric wire W, and a plurality of holding portions 2. Connectors 70 are connected to both ends of the electric wire W. The electric wire assembly 60 is inserted into the exterior member 30 and attached to the vehicle body 110 together with the exterior member 30.

[0045] 7 and 8, the jig 300 has a plate-like main body 310 and a pair of support parts 320. The shape of the main body 310 is, for example, rectangular. The support parts 320 support the urging member 50 in a curved state. The support parts 320 protrude from a support surface 310a of the main body 310 in a direction perpendicular to the support surface 310a.

[0046] The shape of the support portion 320 in a plan view is substantially L-shaped. The pair of support portions 320 face each other in the width direction D of the main body 310. The support portion 320 has a support wall 321 and an opposing wall 322. The support wall 321 is a portion that supports an end portion of the urging member 50, and extends in a direction perpendicular to the width direction D. The opposing wall 322 protrudes in the width direction D relative to the support wall 321. The opposing wall 322 faces a tip surface of the urging member 50.

[0047] The method of routing the electric wire W to the urging member 50 using the jig 300 includes an installation step, an installation step, and a fixing step. The installation step is a step of supporting the urging member 50 by the jig 300. As shown in Fig. 9, the urging member 50 is set in the jig 300 in a state in which it is elastically deformed to form a substantially U-shape.

[0048] In the installation process, the worker elastically deforms the urging member 50 so as to have an arc-shaped curved portion 55. The worker causes the urging member 50 deformed to have a shape having the curved portion 55 to be supported by the jig 300. Both ends of the urging member 50 are supported by a pair of support portions 320. The urging member 50 is placed on the support surface 310a so that the end is aligned with the support wall 321. One end of the urging member 50 is supported by one support wall 321. The other end of the urging member 50 is supported by the other support wall 321. The two support walls 321 support the urging member 50 from both sides in the width direction D, and maintain the shape of the urging member 50 in a U-shape. The urging member 50 supported by the jig 300 has an outer surface 50e. The outer surface 50e is the radially outer surface of the curved portion 55. In other words, the outer surface 50e is one of the two main surfaces that the urging member 50 has, which is located on the outer side of the curved portion 55.

[0049] The wiring process is a process of wiring the electric wire W to the urging member 50 supported by the jig 300. In the wiring process, the worker wires the electric wire W along the urging member 50 from one end of the urging member 50 to the other end of the urging member 50. As shown in Fig. 10, the electric wire W is disposed along the outer surface 50e of the urging member 50. Therefore, the electric wire W is located radially outward from the curved portion 55.

[0050] The fixing step is a step of fixing the electric wire W to the urging member 50. The worker fixes the electric wire W to at least two points on the urging member 50 using the holding parts 2. The holding parts 2 are arranged on both sides of the portion of the electric wire W that is along the curved part 55. The electric wire assembly 60 in FIG. 7 has a holding part 2g arranged on one side of the curved part 55 and a holding part 2h arranged on the other side of the curved part 55. The holding parts 2g and 2h are arranged near the ends of the urging member 50. The holding parts 2g and 2h are, for example, adhesive tape or cable ties.

[0051] When the biasing member 50 is removed from the jig 300, the biasing member 50 becomes linear. As a result, a slack retaining portion Ws is formed in the electric wire W as shown in FIG. 5. According to the wiring method using the jig 300, the length of the slack retaining portion Ws can be set to an appropriate length. When the electric wire W is wired to the biasing member 50 supported by the jig 300, a slack may be added to the length of the electric wire W along the biasing member 50. That is, the electric wire W may be wired such that the length of the electric wire W along the outer surface 50e is greater than the length of the outer surface 50e.

[0052] The holding portion 2 may hold the electric wire W so as to position the slack holding portion Ws at a predetermined position of the exterior member 30. The electric wire W shown in Fig. 11 has a first holding portion Ws1 and a second holding portion Ws2 as the slack holding portion Ws. The first holding portion Ws1 is formed so as to be located at the curved portion 33 when the sliding body 210 is in the fully closed position. The second holding portion Ws2 is formed so as to be located at the curved portion 34 when the sliding body 210 is in the fully open position.

[0053] The exterior member 30 has a first portion 30c that forms a curved portion 33 when fully closed, and a second portion 30d that forms a curved portion 34 when fully open. The first portion 30c is located near the second end 30b. The second portion 30d is located near the first end 30a. The biasing member 50 has a first portion 50c that corresponds to the first portion 30c of the exterior member 30, and a second portion 50d that corresponds to the second portion 30d of the exterior member 30.

[0054] The retaining portion 2 has a first retaining portion 2a, a second retaining portion 2b, a third retaining portion 3c, and a fourth retaining portion 2d. The first retaining portion 2a and the second retaining portion 2b form a first retaining portion Ws1 in the first portion 50c. The first retaining portion 2a is disposed at one end of the first portion 50c and fixes the electric wire W to the biasing member 50. The second retaining portion 2b is disposed at the other end of the first portion 50c and fixes the electric wire W to the biasing member 50.

[0055] The third retaining portion 3c and the fourth retaining portion 2d form a second retaining portion Ws2 in the second portion 50d. The third retaining portion 3c is disposed at one end of the second portion 50d and fixes the electric wire W to the biasing member 50. The fourth retaining portion 2d is disposed at the other end of the second portion 50d and fixes the electric wire W to the biasing member 50.

[0056] The length of the first holding portion Ws1 is determined based on, for example, the value of the radius R1 of the curved portion 33 and the position of the electric wire W relative to the urging member 50. The length of the first holding portion Ws1 may be determined, for example, depending on whether the electric wire W is disposed on the radial inner side or the radial outer side relative to the urging member 50. When the electric wire W is disposed on the outer side relative to the urging member 50, the length of the first holding portion Ws1 may be greater than when the electric wire W is disposed on the inner side.

[0057] The length of the second holding portion Ws2 is determined based on, for example, the value of the radius R2 of the curved portion 34 and the position of the electric wire W relative to the urging member 50. When the electric wire W is disposed on the outer side relative to the urging member 50, the length of the second holding portion Ws2 may be greater than when the electric wire W is disposed on the inner side.

[0058] In the sunroof 200 of this embodiment, the radius R1 when fully closed is smaller than the radius R2 when fully open. In this case, the length of the first holding portion Ws1 may be set to a value larger than the length of the second holding portion Ws2.

[0059] The electric wire W in Fig. 11 has a third retaining portion Ws3, which is a slack retaining portion Ws, between the first retaining portion Ws1 and the second retaining portion Ws2. That is, the second retaining portion 2b and the third retaining portion 3c retain the electric wire W so as to form the third retaining portion Ws3 between the two retaining portions 2b and 2c. When a plurality of slack retaining portions Ws are formed in this manner, uneven distribution of the slack retaining portions Ws is suppressed.

[0060] The retaining portion 2 is not limited to a portion that fixes the electric wire W to the biasing member 50. The retaining portion 2 may hold the electric wire W at the fixing portions 10 and 20, for example. FIG. 12 shows a retaining portion 2e disposed at the first fixing portion 10 and a retaining portion 2f disposed at the second fixing portion 20. The retaining portion 2e may be a clamp integrally provided at the first fixing portion 10. The retaining portion 2f may be a clamp integrally provided at the second fixing portion 20. These clamps can hold the electric wire W and form a slack retaining portion Ws inside the exterior member 30.

[0061] The holding portion 2e may be an adhesive tape, a cable tie, or the like that fixes the electric wire W to the holding member of the first fixing portion 10. The holding portion 2f may be an adhesive tape, a cable tie, or the like that fixes the electric wire W to the holding member of the second fixing portion 20.

[0062] The holding portions 2e and 2f hold the electric wire W such that the electric wire W has a slack holding portion Ws inside the exterior member 30. That is, the holding portions 2e and 2f hold the electric wire W such that the length of the electric wire W accommodated inside the exterior member 30 is greater than the length of the exterior member 30.

[0063] When the retaining portions 2e, 2f are arranged on the fixed portions 10, 20, the wiring structure 1 does not need to have the urging member 50. Also, when the wiring structure 1 has the urging member 50, the retaining portions 2e, 2f may be arranged on the fixed portions 10, 20. In this case, the electric wire W does not need to be fixed to the urging member 50.

[0064] As described above, the wiring structure 1 of the present embodiment has the first fixing portion 10, the second fixing portion 20, the exterior member 30, the electric wire W, and the holding 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. The sliding body 210 moves along the vehicle front-rear direction X with respect to the opening 120a provided in the roof 120 of the vehicle body 110. The exterior member 30 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 is inserted into the exterior member 30. The holding portion 2 holds the electric wire W.

[0065] The first fixing portion 10 and the second fixing portion 20 hold the exterior member 30 such that a curved portion 35 is formed between the first end portion 30a and the second end portion 30b, where the exterior member 30 curves toward the vehicle front-rear direction X. The holding portion 2 holds at least two points of the electric wire W such that the electric wire W has a slack retaining portion Ws inside the exterior member 30. By having the electric wire W have the slack retaining portion Ws inside the exterior member 30, stress generated in the electric wire W when the exterior member 30 deforms is alleviated. Therefore, the wiring structure 1 of the present embodiment can improve the durability of the electric wire W against bending.

[0066] The wiring structure 1 may have a biasing member 50 that is inserted into the exterior member 30. The retaining portion 2 can form a slack retaining portion Ws in the electric wire W along the biasing member 50 by fixing the electric wire W to the biasing member 50. With this configuration, it is possible to position the slack retaining portion Ws at a desired position inside the exterior member 30.

[0067] The retaining portion 2 may be disposed in each of the first fixed portion 10 and the second fixed portion 20. In this case, the retaining portion 2e of the first fixed portion 10 and the retaining portion 2f of the second fixed portion 20 hold the electric wire W such that the electric wire W has a slack retaining portion Ws inside the exterior member 30. With this configuration, it is possible to arrange the slack retaining portion Ws over the entire length of the exterior member 30.

[0068] The sliding body 210 of this embodiment moves in the vehicle front-rear direction X between a fully closed position where the opening 120a is closed and a fully open position where the opening 120a is opened. The holding portion 2 may hold the electric wire W such that the slack holding portion Ws is located at the curved portion 33 when the sliding body 210 is in the fully closed position. The first holding portion 2a and the second holding portion 2b in FIG. 11 form a first holding portion Ws1 located at the curved portion 33. The holding portion 2 may hold the electric wire such that the slack holding portion Ws is located at the curved portion 34 when the sliding body 210 is in the fully open position. The third holding portion 3c and the fourth holding portion 2d in FIG. 11 form a second holding portion Ws2 located at the curved portion 34.

[0069] The holding portion 2 shown in FIG. 11 forms both the first holding portion Ws1 and the second holding portion Ws2, but alternatively, the holding portion 2 may form only one of the first holding portion Ws1 and the second holding portion Ws2.

[0070] The wiring method of this embodiment includes an installation step, a wiring step, and a fixing step. The installation step is a step of elastically deforming the plate-shaped biasing member 50 and supporting the biasing member 50 deformed into a shape having a curved portion 55 by the jig 300. The wiring step is a step of wiring the electric wire W to the biasing member 50 supported by the jig 300. The fixing step is a step of fixing the electric wire W by the holding portion 2 to at least two locations on the biasing member 50. In the wiring step, the electric wire W is wired to the outer surface 50e of the curved portion 55 of the biasing member 50. In the fixing step, both sides of the portion of the electric wire W along the curved portion 55 are fixed to the biasing member 50 by the holding portion 2. According to the wiring method of this embodiment, it is possible to form an appropriate slack retaining portion Ws.
