FIG. 8 shows the VIII-VIII cross-section of FIG. 7.

[0012] As shown in FIG. 1, the cable structure 1 of this embodiment is mounted on a vehicle 100 such as an automobile. The cable structure 1 has a protector 2, a rotating member 3, an exterior member 5, and an electric wire W. The cable structure 1 connects the vehicle body 110 and the sliding door 120 of the vehicle 100. The sliding door 120 moves relative to the vehicle body 110 along the first direction X. The first direction X is the longitudinal direction of the vehicle 100. The sliding door 120 slides, for example, by the operation of a link mechanism that connects the vehicle body 110 and the sliding door 120. The sliding door 120 may slide while being guided by a rail disposed on the vehicle body 110.

[0013] The protector 2 is disposed on the sliding door 120 and held by the sliding door 120. The protector 2 is molded, for example, from an insulating synthetic resin. The protector 2 rotatably supports the rotating member 3. The rotating member 3 has a cylindrical portion 31 that holds an end portion of the exterior member 5. The tip of the cylindrical portion 31 protrudes outward from the protector 2.

[0014] On the vehicle body 110, a body protector 130 corresponding to the protector 2 is arranged. The body protector 130 is formed of, for example, an insulating synthetic resin. The body protector 130 rotatably supports a rotating member 140. The rotating member 140 has a cylindrical portion 141 that holds an end portion of the exterior member 5. The cylindrical portion 141 projects outward from the body protector 130. When the sliding door 120 opens and closes, the protector 2 and the exterior member 5 move in the first direction X. The cylindrical portion 141 rotates while following the movement of the protector 2 and the exterior member 5.

[0015] The sliding door 120 faces the vehicle body 110 in the second direction Y. The second direction Y is the vehicle width direction of the vehicle 100. In the following description, on the second direction Y, the side of the vehicle body 110 with respect to the sliding door 120 is referred to as the vehicle body side Y1, and the side of the sliding door 120 with respect to the vehicle body 110 is referred to as the door side Y2.

[0016] The electric wire W is routed from the vehicle body 110 to the sliding door 120. More specifically, the electric wire W is inserted through the rotating member 140, the exterior member 5, the rotating member 3, and the protector 2 from the body protector 130 and drawn out toward the sliding door 120. The exterior member 5 is a flexible cylindrical protective member, for example, a corrugated tube. The exterior member 5 extends from the rotating member 140 of the vehicle body 110 to the rotating member 3 of the sliding door 120.

[0017] The sliding door 120 moves between the fully closed position P1 and the fully open position P3. In FIG. 1, the protector 2A shows the protector 2 when the sliding door 120 is in the fully closed position P1, and the protector 2C shows the protector 2 when the sliding door 120 is in the fully open position P3. Also, the protector 2B shows the protector 2 when the sliding door 120 is in the half-open position P2. Also, the rotating members 3A, 3B, 3C show the rotating member 3 when the sliding door 120 is in each position P1, P2, P3.

[0018] The fully closed position P1 is the front end X1 of the sliding door 120 in the range of movement along the first direction X. The fully open position P3 is the rear end X2 of the sliding door 120 in the range of movement along the first direction X. The fully closed position P1 is the position of the sliding door 120 when it closes the opening of the vehicle 100. The fully open position P3 is the position of the sliding door 120 when it opens the opening.

[0019] The sliding door 120 moves from the fully closed position P1, through the half-open position P2, to the fully open position P3. When the sliding door 120 is in the fully closed position P1, the electric wire W and the exterior member 5 extend from the protector 2A toward the rear X2 along the first direction X. The cylindrical portion 31 of the rotating member 3A protrudes from the protector 2A toward the rear X2.

[0020] When the sliding door 120 is in the fully closed position P1, the exterior member 5 and the electric wire W curve toward the door side Y2. In other words, the wiring structure 1 of this embodiment is configured to curve the electric wire W and the exterior member 5 toward the door side Y2 when the sliding door 120 is in the fully closed position P1. The curved electric wire W and exterior member 5 apply a force F1 to the rotating member 3.

[0021] The wiring structure 1 of this embodiment includes a drive structure 10 that moves the position of the rotating member 3 so that the bending radius formed in the electric wire W when the sliding door 120 is in the fully open position P3 is not too small, as will be described below.

[0022] As shown in Figure 2, the protector 2 has a body 6 and a cover 7. The body 6 and cover 7 are molded from, for example, an insulating synthetic resin. The body 6 and cover 7 face each other in the vehicle's vertical direction Z. When the cover 7 is assembled to the body 6, a space is formed to accommodate the rotating member 3 and the electric wire W.

[0023] The rotating member 3 has a main body 8 and a cover 9. The main body 8 and the cover 9 are molded from, for example, an insulating synthetic resin. The main body 8 and the cover 9 face each other in the vehicle's vertical direction Z. When the cover 9 is assembled to the main body 8, a passage is formed through which the electric wire W is inserted.

[0024] The cylindrical portion 31 of the rotating member 3 has a substantially rectangular cylindrical shape. The cylindrical portion 31 has a bottom wall 31a, a top wall 31b, and a pair of side walls 31c, 31d. The bottom wall 31a and the top wall 31b face each other in the vehicle's vertical direction Z. The side walls 31c, 31d face each other in a direction perpendicular to the vehicle's vertical direction Z. The bottom wall 31a, the top wall 31b, and the pair of side walls 31c, 31d form a passage with a rectangular cross-sectional shape. The electric wire W is inserted through the cylindrical portion 31 and routed through the cable routing path 20 of the protector 2.

[0025] The rotating member 3 has a rotating shaft 32, a sub-shaft 33, and a guide boss 34. The rotating shaft 32 is the main rotating shaft of the rotating member 3 and is rotatably supported by the protector 2. The sub-shaft 33 is a secondary rotating shaft of the rotating member 3. The sub-shaft 33 is inserted into the first groove 23 of the protector 2, which will be described later. The guide boss 34 is guided by the protector 2 when the rotating member 3 rotates.

[0026] The rotating shaft 32, the sub-shaft 33, and the guide boss 34 are located at the axial end of the rotating member 3. More specifically, the rotating shaft 32, the sub-shaft 33, and the guide boss 34 are located at the end of the protector 2 from which the electric wire is drawn out toward the cable routing 20.

[0027] The rotation axis 32 has a rotation axis 32A located on the bottom wall 31a and a rotation axis 32B located on the top wall 31b. The two rotation axes 32A and 32B are located on the same axis. Rotation axis 32A protrudes from the bottom wall 31a toward the side opposite to the top wall 31b. Rotation axis 32B protrudes from the top wall 31b toward the side opposite to the bottom wall 31a.

[0028] The sub-axis 33 has a sub-axis 33A located on the bottom wall 31a and a sub-axis 33B located on the top wall 31b. The two sub-axis 33A and 33B are located on the same axis. Sub-axis 33A protrudes from the bottom wall 31a toward the side opposite to the top wall 31b. Sub-axis 33B protrudes from the top wall 31b toward the side opposite to the bottom wall 31a. The sub-axis 33 is positioned spaced apart from the rotation axis 32. That is, sub-axis 33A protrudes from a position spaced apart from the rotation axis 32A on the bottom wall 31a. Sub-axis 33B protrudes from a position spaced apart from the rotation axis 32B on the top wall 31b.

[0029] The guide boss 34 has a guide boss 34A located on the bottom wall 31a and a guide boss 34B located on the top wall 31b. The two guide bosses 34A and 34B are located on the same axis. Guide boss 34A protrudes from the bottom wall 31a toward the side opposite to the top wall 31b. Guide boss 34B protrudes from the top wall 31b toward the side opposite to the bottom wall 31a. The guide boss 34 is spaced apart from the rotation axis 32 and is located on the side opposite to the rotation axis 32 toward the sub-axis 33. In other words, the rotation axis 32 is located between the sub-axis 33 and the guide boss 34.

[0030] The protector 2 has a cable routing path 20, a recess 22, a first groove 23, and a second groove 24. The cable routing path 20 is formed in the body 6 of the protector 2. The cable routing path 20 is a groove that extends along a first direction X, which is the longitudinal direction of the vehicle. The recess 22 rotatably supports the rotation axis 32 of the rotating member 3. The first groove 23 extends in an arc around the recess 22 and guides the sub-axis 33 of the rotating member 3. The second groove 24 extends in an arc around the recess 22 and guides the guide boss 34 of the rotating member 3. The second groove 24 is located on the opposite side of the recess 22 from the side of the first groove 23. In other words, the recess 22 is located between the first groove 23 and the second groove 24.

[0031] The drive structure 10 of this embodiment includes a rotating shaft 32, a sub-shaft 33, a recess 22, and a first groove 23. The drive structure 10 may further include a guide boss 34 and a second groove 24. The drive structure 10 may further include an electric wire W and an outer covering member 5.

[0032] As shown in Figure 3, the shape of the rotation axis 32 when viewed from the axial direction of the rotation axis 32 is approximately rectangular. The rotation axis 32 has two sides 32s. The two sides 32s are aligned along the axial direction of the rotation axis 32 and are positioned on either side with the central axis of the rotation axis 32 in between. The shape of the sides 32s in a cross section perpendicular to the axis of the rotation axis 32 is an arc shape centered on the axis of the rotation axis 32. The sides 32s are rotatably supported by the recess 22 of the protector 2. The rotation axis 32 has a longitudinal length L1. Length L1 is the distance from the center of one side 32s to the center of the other side 32s.

[0033] The shape of the illustrated sub-axis 33 is cylindrical or cylindrical. That is, the cross-sectional shape of the sub-axis 33 in a section perpendicular to the axis of the sub-axis 33 is circular. The sub-axis 33 is positioned perpendicular to the line connecting the two sides 32s with respect to the axis of rotation 32. That is, the line connecting the central axis of the axis of rotation 32 and the sub-axis 33 is perpendicular to the line connecting the centers of the two sides 32s.

[0034] The illustrated shape of the guide boss 34 is approximately a triangular prism. The guide boss 34 has a side surface 34s. The side surface 34s faces away from the side of the rotation axis 32. That is, the side surface 34s faces outward in the radial direction with respect to the rotation axis 32. The cross-sectional shape of the guide boss 34 in a cross section perpendicular to the axis of the guide boss 34 is approximately a triangle with its vertex facing the rotation axis 32. The distance from the rotation axis 32 to the guide boss 34 is shorter than the distance from the rotation axis 32 to the sub-axis 33.

[0035] The arrangement and shape of the rotating shaft 32B, sub-shaft 33B, and guide boss 34B located on the cover 9 of the rotating member 3 are the same as the arrangement and shape of the rotating shaft 32A, sub-shaft 33A, and guide boss 34A of the main body 8.

[0036] As shown in Figures 4 and 5, the body 6 of the protector 2 has a bottom wall 61 and a pair of side walls 62a and 62b. The pair of side walls 62a and 62b are erected from the widthwise ends of the bottom wall 61. The bottom wall 61 and the pair of side walls 62a and 62b form a groove-shaped cable routing path 20 through which the electric wires W are routed. The protector 2 is fixed to the sliding door 120 with the side wall 62a facing the vehicle body side Y1.

[0037] The cable routing 20 has an inlet 20a and an outlet 20b. The inlet 20a is the end through which the electric wire W is pulled out toward the vehicle body 110. In the illustrated protector 2, the rear end X2 of the cable routing 20 is the inlet 20a. The outlet 20b is the end through which the electric wire W is pulled out toward the sliding door 120. In the illustrated protector 2, the front end X1 of the cable routing 20 is the outlet 20b.

[0038] The recess 22, the first groove 23, and the second groove 24 are located at the entrance portion 20a of the cable routing 20. The side wall 62a on the vehicle body side Y1 is provided in a range that does not interfere with the rotating member 3 which rotates while being supported by the protector 2. With the protector 2 fixed to the sliding door 120, the first groove 23 is located on the vehicle body side Y1 relative to the recess 22. The second groove 24 is located on the door side Y2 relative to the recess 22.

[0039] The protector 2 of this embodiment has recesses 22, namely a recess 22A located in the main body 6 and a recess 22B located in the cover 7. The protector 2 also has first grooves 23, namely a first groove 23A located in the main body 6 and a first groove 23B located in the cover 7. The protector 2 also has a second groove 24, namely a second groove 24A located in the main body 6.

[0040] As shown in Figures 4 and 5, the recess 22 has a first recess 25 and a guide recess 26. The recess 22A of the main body 6 is a through hole that penetrates the bottom wall 61. In this specification, the position of the rotating shaft 32 when it is rotatably supported by the first recess 25 is referred to as the "first position". In other words, the first recess 25 supports the rotating shaft 32 of the rotating member 3 in the first position.

[0041] Furthermore, in this specification, the position of the rotating shaft 32 when it is housed and locked in the guide recess 26 is referred to as the "second position". The guide recess 26 guides the rotating shaft 32 of the rotating member 3 to the second position and locks the rotating shaft 32 in the second position. The second position is at a position Y1 on the vehicle body side than the first position.

[0042] When the recess 22 is viewed from above, the shape of the first recess 25 is an arc shape. The first recess 25 has an inner diameter D1. The inner diameter D1 corresponds to the length L1 of the rotation axis 32. The value of the inner diameter D1 is equal to or slightly greater than the length L1 of the rotation axis 32. That is, the value of the inner diameter D1 is set so that the rotation axis 32 can be rotatably supported.

[0043] The guide recess 26 extends radially outward from the first recess 25. Here, the radial direction is the radial direction centered on the central axis of the first recess 25. The guide recess 26 extends toward the vehicle body side Y1 from the first recess 25. The guide recess 26 has a width W1. The value of the width W1 is smaller than the value of the inner diameter D1 and smaller than the value of the length L1 of the rotating shaft 32. Also, the value of the width W1 is larger than the length of the shorter side in the cross-section of the rotating shaft 32. The value of the width W1 is set to allow the rotating shaft 32 to enter the guide recess 26 when the rotational position of the rotating shaft 32 is at a predetermined position.

[0044] The first groove 23 is positioned concentrically with the first recess 25. That is, the first groove 23 extends circumferentially about the central axis of the first recess 25. The first groove 23 has a first end 23s and a second end 23e. The first end 23s is the position of the sub-shaft 33 when the sliding door 120 is in the fully closed position. The illustrated first end 23s is the rear X2 end of the first groove 23. The second end 23e is the end that locks the sub-shaft 33 as the sliding door 120 moves toward the fully open position. The illustrated second end 23e is the front X1 end of the first groove 23. The first groove 23 has an arc-shaped guide surface 23g that guides the sub-shaft 33.

[0045] The second groove 24 is positioned concentrically with the first recess 25. That is, the second groove 24 extends in the circumferential direction about the central axis of the first recess 25. The second groove 24 has a first end 24s and a second end 24e. The first end 24s is the position of the guide boss 34 when the sliding door 120 is in the fully closed position. The illustrated first end 24s is the front end X1 of the second groove 24. The second end 24e is the position of the guide boss 34 when the sliding door 120 is in the fully closed position. The second end 24e is the rear end X2 of the second groove 24. The second groove 24 has an arc-shaped guide surface 24g that guides the guide boss 34.

[0046] As shown in Figure 6, the cover 7 of the protector 2 has a top wall 71. The top wall 71 faces the bottom wall 61 of the main body 6 in the vehicle vertical direction Z. The top wall 71 covers the cable routing 20 from above, forming a rectangular tubular passage. The top wall 71 is provided with a recess 22B and a first groove 23B. The recess 22B faces the recess 22A of the main body 6. The first groove 23B faces the first groove 23A of the main body 6. The position and shape of the recess 22B and the first groove 23B correspond to the position and shape of the recess 22A and the first groove 23A. The cover 7 may also be provided with a second groove 24B corresponding to the second groove 24A.

[0047] Figure 7 shows the wiring structure 1 when the sliding door 120 is in the fully closed position. That is, the rotating member 3 in Figure 7 corresponds to the rotating member 3A shown in Figure 1. The cylindrical portion 31 of the rotating member 3 protrudes from the protector 2 toward the rear side X2 in the first direction X. The electric wire W is drawn out from the rotating member 3 inside the protector 2 and extends from the inlet portion 20a to the outlet portion 20b of the wiring path 20. The electric wire W drawn out from the outlet portion 20b is connected to the device of the sliding door 120.

[0048] Figure 8 shows the VIII-VIII section of Figure 7. When the sliding door 120 is in the fully closed position, the rotation axis 32 of the rotating member 3 is located in the first recess 25 of the recess 22. In this embodiment, the wiring structure 1 is configured such that when the sliding door 120 is in the fully closed position P1, the exterior member 5 and the electric wire W press the rotating member 3 toward the protector 2 by a force F1 (see Figure 1). The force F1 is a force directed toward the door side Y2. The rotation axis 32 of the rotating member 3 is positioned in the first recess 25 by the force F1. The rotational position of the rotation axis 32 when the sliding door 120 is in the fully closed position is a rotational position in which the rotation axis 32 cannot enter the guide recess 26.

[0049] As shown in Figure 8, when the sliding door 120 is in the fully closed position, the sub-shaft 33 is located at the first end 23s of the first groove 23, and the guide boss 34 is located at the first end 24s of the second groove 24.

[0050] When the sliding door 120 slides from the fully closed position to the fully open position, the pivot shaft 32 rotates in the first position while being supported by the first recess 25. At this time, the sub-shaft 33 moves along an arc-shaped path toward the front X1 while being guided by the first groove 23. The guide boss 34 moves along an arc-shaped path toward the rear X2 while being guided by the second groove 24.

[0051] When the rotating member 3 rotates relative to the protector 2, the rotation angle θ of the rotating member 3 changes. In this specification, the rotation angle θ of the rotating member 3 has a reference angle, a first angle θ1, and a second angle θ2. In Figure 8, the cylindrical portion 31 is shown by a dashed line when the rotation angle θ of the rotating member 3 is the reference angle. When the sliding door 120 is in the fully closed position, the cylindrical portion 31 protrudes from the protector 2 toward the rear side X2 in the first direction X. That is, the cylindrical portion 31 extends from the rotation axis 32 toward the side opposite to the cable routing 20. The value of the rotation angle θ at this time is set to 0, which is the reference angle. The positive direction of the rotation angle θ is, for example, the counterclockwise direction in Figure 8. In this case, the rotation angle θ increases as the sliding door 120 slides from the fully closed position to the fully open position.

[0052] Figure 9 shows the wiring structure 1 when the rotation angle θ of the rotating member 3 is the first angle θ1. At this time, the position of the sliding door 120 is between the fully closed position and the fully open position. The cylindrical portion 31 of the rotating member 3 protrudes from the protector 2 toward the vehicle body side Y1 and slightly toward the front side X1. In other words, the cylindrical portion 31 protrudes diagonally forward from the protector 2. The electric wire W is curved inside the protector 2 to form a roughly V shape.

[0053] Figure 10 shows the cross-section of Figure 9. The cross-sectional position in Figure 10 is the same as the cross-sectional position in Figure 8. When the rotation angle θ is the first angle θ1, the sub-shaft 33 is positioned at the second end 23e of the first groove 23, as shown in Figure 10. The second end 23e of the first groove 23 locks the sub-shaft 33. This restricts the rotational movement of the rotation shaft 32 in the first recess 25.

[0054] The longitudinal axis of the cross-section of the rotating shaft 32 is aligned with the extending direction of the guide recess 26. In other words, the longitudinal axis of the cross-section of the rotating shaft 32 is aligned with the vehicle width direction. The rotating shaft 32 has one side 32s facing the entrance of the guide recess 26. The width W1 of the guide recess 26 is greater than the width of the rotating shaft 32 in the short side direction. That is, when the rotating shaft 32 is in the rotation position shown in Figure 10, the guide recess 26 can accommodate the rotating shaft 32. The guide boss 34 is located between the first end 24s and the second end 24e.

[0055] As the sliding door 120 slides further towards the fully open position from the position corresponding to Figure 10, the rotating member 3 rotates around the sub-axis 33 as its center of rotation. As a result, the rotating shaft 32 moves from the first recess 25 to the guide recess 26, as shown by arrow AR1 in Figure 10. In other words, the drive structure 10 of this embodiment moves the rotating shaft 32 from the first position to the second position when the rotation angle θ of the rotating member 3 increases beyond the first angle θ1.

[0056] Figure 11 shows the cable routing structure 1 when the rotation angle θ of the rotating member 3 is the second angle θ2. The second angle θ2 is a larger angle than the first angle θ1. The exemplified second angle θ2 is the rotation angle θ when the sliding door 120 is in the fully open position. In other words, the rotating member 3 in Figure 11 corresponds to the rotating member 3C shown in Figure 1. The cylindrical portion 31 of the rotating member 3 protrudes from the protector 2 toward the vehicle body side Y1 and toward the front side X1. In other words, the second angle θ2 is the rotation angle θ in which the cylindrical portion 31 and the cable routing path 20 form an acute angle.

[0057] Figure 12 shows a cross-section of Figure 11. The cross-sectional position in Figure 12 is the same as the cross-sectional position in Figure 8. When the rotation angle θ is the second angle θ2, as shown in Figure 12, the rotating shaft 32 enters deep into the guide recess 26 and is housed in the guide recess 26. The wall of the vehicle body side Y1 in the guide recess 26 locks the rotating shaft 32. The position of the rotating shaft 32 in Figure 12 is the second position where it is housed and locked in the guide recess 26. The second position of the rotating shaft 32 is at a position of vehicle body side Y1 than the first position in Figure 10. When the rotating shaft 32 is in the second position, the sub-shaft 33 is located at the second end 23e of the first groove 23, and the guide boss 34 has reached the second end 24e of the second groove 24.

[0058] Figure 13 shows the interior of the protector 2 when the rotation angle θ is the second angle θ2. The central axis 32x of the rotation shaft 32 is offset from the central axis 25x of the first recess 25. The central axis 32x of the rotation shaft 32 is offset from the central axis 25x of the first recess 25 toward the vehicle body side Y1 and also offset toward the rear side X2. In Figure 13, the dashed line indicates the position of the rotating member 3 when the rotation angle θ is the first angle θ1.

[0059] In the wiring structure 1 of this embodiment, when the rotation angle θ changes from the first angle θ1 to the second angle θ2, the position of the rotation axis 32 moves toward the vehicle body side Y1. This makes it less likely that the bending radius of the electric wire W will be too small. Figure 14 shows a comparative example of the rotating member 103. In the comparative example of the rotating member 103, the center of rotation is fixed to the central axis 25x of the first recess 25. That is, while the sliding door 120 slides from the fully closed position to the fully open position, the rotating member 103 rotates in the first position with the central axis 25x as the center of rotation.

[0060] Figure 14 shows the path Tr1 of the electric wire W in this embodiment and the path Tr100 of the electric wire W in a comparative example. Both paths Tr1 and Tr100 are the paths of the electric wire W when the sliding door 120 is in the fully open position.

[0061] As shown in Figure 12, path Tr1 of this embodiment is the path of the electric wire W when the rotation axis 32 of the rotating member 3 is in the second position. Path Tr100 of the comparative example is the path of the electric wire W when the rotation center of the rotating member 103 does not move from the central axis 25x. As shown in Figure 14, path Tr1 of this embodiment has a larger bending radius compared to path Tr100 of the comparative example. In other words, the wiring structure 1 of this embodiment can prevent the bending radius of the electric wire W from being too small when the sliding door 120 is in the fully open position.

[0062] When the sliding door 120 slides from the fully open position to the fully closed position, the drive structure 10 moves the rotating shaft 32 from the second position to the first position. When the sliding door 120 slides from the state shown in Figure 12 toward the fully closed position, a force is generated that moves the rotating shaft 32 from the guide recess 26 toward the first recess 25. This force is based, for example, on the reaction force of the electric wire W and the reaction force of the exterior member 5. The reaction forces of the electric wire W and the exterior member 5 press the rotating member 3 toward the door side Y2. At this time, the second end 23e of the first groove 23 locks the sub-shaft 33, causing the rotating member 3 to rotate around the sub-shaft 33 as the center of rotation. This rotation causes the rotating shaft 32 to move from the guide recess 26 to the first recess 25. That is, the rotating shaft 32 moves from the second position to the first position.

[0063] When the rotation angle θ of the rotating member 3 reaches the first angle θ1, the rotating shaft 32 is housed in the first recess 25 and positioned in the first position. This allows the first recess 25 to rotatably support the rotating shaft 32. As the sliding door 120 slides further toward the fully closed position, the rotating member 3 rotates around the rotating shaft 32 as its center of rotation. When the rotating shaft 32 is positioned in the first position, the rotating member 3 is housed in the back of the protector 2 when viewed from the vehicle body side Y1. In other words, the rotating member 3 is positioned in a location that is difficult to see when viewed from the vehicle body side Y1. This improves the appearance of the cable routing structure 1.

[0064] As described above, the wiring structure 1 of this embodiment includes an electric wire W routed between the vehicle body 110 and the sliding door 120 of the vehicle 100, a protector 2, a rotating member 3, and a drive structure 10. The protector 2 is positioned on the sliding door 120 and has a wiring path 20 through which the electric wire W is routed. The wiring path 20 of the protector 2 extends in the longitudinal direction of the vehicle. The rotating member 3 has a rotating shaft 32 and a cylindrical portion 31 through which the electric wire W is inserted. The rotating member 3 is positioned at the entrance portion 20a of the wiring path 20. The entrance portion 20a is the portion of the wiring path 20 through which the electric wire W is pulled out toward the vehicle body 110.

[0065] The drive structure 10 moves the rotating shaft 32 in the vehicle width direction between a first position and a second position according to the rotation angle θ when the rotating member 3 rotates relative to the protector 2. The rotation angle θ has a reference angle which is the minimum angle, a first angle θ1, and a second angle θ2 which is the maximum angle. The reference angle is the rotation angle θ when the sliding door 120 is in the fully closed position and the cylindrical portion 31 extends from the rotating shaft 32 toward the side opposite to the cable routing 20.

[0066] The second angle θ2 is the rotation angle θ at which the cylindrical section 31 and the cable routing 20 form an acute angle when the sliding door 120 is in the fully open position. The first angle θ1 is the rotation angle θ between the reference angle and the second angle θ2.

[0067] The drive structure 10 is configured to position the rotating shaft 32 in a first position when the rotation angle θ is less than or equal to a first angle θ1. The drive structure 10 is configured to move the rotating shaft 32 from the first position to a second position when the rotation angle θ increases beyond the first angle θ1. In the vehicle width direction, the second position is at a position Y1 on the vehicle body side than the first position. The wiring structure 1 of this embodiment can suppress the bending radius of the electric wire W from being too small.

[0068] The drive structure 10 of this embodiment includes a sub-shaft 33 provided on the rotating member 3, a recess 22, and a first groove 23. The recess 22 is provided on the protector 2 and rotatably supports the rotating shaft 32. The first groove 23 is a groove that guides the sub-shaft 33. The sub-shaft 33 is a shaft portion located at a position spaced apart from the rotating shaft 32 on the rotating member 3.

[0069] The recess 22 has a first recess 25 positioned in a first position and a guide recess 26 that guides the rotation shaft 32 from the first position to a second position. The shape of the first recess 25 in a cross section perpendicular to the axial direction of the rotation shaft 32 is an arc shape. The guide recess 26 extends radially outward from the first recess 25. The first groove 23 extends in an arc shape concentric with the first recess 25. When the rotation angle θ exceeds a first angle θ1, the first groove 23 locks the sub-shaft 33 and moves the rotation shaft 32 from the first recess 25 to the guide recess 26. Such a drive structure 10 can appropriately move the rotation shaft 32 by utilizing the movement of the rotating member 3.
