Fig. 10 shows the X-X section of Fig. 9 .

FIG1 shows a sliding seat 10 to which a wiring structure 1 for a sliding seat of the present embodiment is applied. The sliding seat 10 is arranged in a vehicle 100. The sliding seat 10 is a seat in the rear row of the vehicle 100, for example, a seat in the third row from the front. As shown in FIG9 and the like, the wiring structure 1 for a sliding seat of the present embodiment is a wiring structure for electrically connecting the body side of the vehicle 100 to the sliding seat 10 using a wiring harness 2. The wiring harness 2 has, for example, a cylindrical outer casing and a plurality of wires housed inside the outer casing. The plurality of wires include, for example, a power line and a signal line.

As shown in FIG. 1 , a vehicle 100 has an interior component 5. The interior component 5 is a component constituting a side wall of a vehicle compartment in the vehicle 100. The interior component 5 is fixed to the inner surface side relative to the vehicle body panel, for example. The interior component 5 may also be a component formed of resin. The interior component 5 extends along the vehicle front-rear direction X and the vehicle up-down direction H. The interior component 5 is supported by, for example, a floor component 102.

The sliding seat 10 of the present embodiment is configured to be able to slide along the vehicle front-rear direction X. The sliding seat 10 has a sliding body 7, a seat cushion 8, a seat back 9, and a sliding member 11. The vehicle 100 has a track 101 for guiding the sliding body 7. The track 101 is arranged on the outside of the vehicle relative to the interior 5 and is fixed to the vehicle body. The track 101 extends along the vehicle front-rear direction X. The sliding body 7 is supported by the track 101 so as to be able to slide. That is, the sliding body 7 is supported by the vehicle body of the vehicle 100 in a manner that it can slide along the vehicle front-rear direction X. The sliding member 11 is supported by the track arranged on the floor member 102 so as to be able to slide freely.

The sliding seat 10 of the present embodiment is configured to enable the seat cushion 8 to be popped up. The seat cushion 8 is connected to the sliding body 7 in a manner that allows relative rotation with respect to the sliding body 7. The rotation axis of the seat cushion 8 is along the vehicle front-rear direction X. FIG. 2 shows the sliding seat 10 in which the seat cushion 8 is popped up. In the following description, the state in which the seat cushion 8 is popped up in the sliding seat 10 is simply referred to as the "pop-up state". In addition, in the sliding seat 10, the state in which the seat cushion 8 is unfolded so that the occupant can sit on it is simply referred to as the "expanded state". In the unfolded state, the seat surface of the seat cushion 8 faces the upper side in the vehicle up-down direction H, and the seat back 9 is erected.

When the seat cushion 8 is popped up, first, the seat back 9 falls down, and the seat back 9 is integrated with the seat cushion 8. Thereafter, the seat cushion 8 and the seat back 9 stand up toward the interior 5. The sliding seat 10 is in the popped up state by rotating the seat cushion 8 relative to the slider 7. In the popped up state, the back surface of the seat back 9 faces the interior 5. In the popped up state, the back surface of the seat back 9 may also contact the interior 5.

The sliding body 7 has a sliding member 70 shown in FIG. 3 and an armrest 73 shown in FIG. 4 . As shown in FIG. 3 , the sliding member 70 has a main body 71 and a pair of supporting parts 72, 72. The main body 71 is slidably supported on the rail 101. The interior component 5 has an opposing portion 5a that is opposed to the rail 101 in the vehicle up-down direction H. A through hole 50 is formed in the opposing portion 5a. The through hole 50 penetrates the opposing portion 5a along the plate thickness direction. In addition, the through hole 50 has a width that the main body 71 can be inserted through, and extends along the vehicle front-rear direction X. The main body 71 protrudes from the through hole 50 toward the upper side of the vehicle.

The support portion 72 protrudes upward from the main body 71. The pair of support portions 72, 72 are opposed to each other in the vehicle front-rear direction X. A support hole 72a is formed in the support portion 72. The support hole 72a is a recess or a hole formed along the vehicle front-rear direction X. The support hole 72a rotatably supports the rotation axis of the seat cushion 8. A bearing that supports the rotation axis of the seat cushion 8 may also be provided in the support hole 72a.

The interior component 5 has a groove-shaped recessed portion 51 extending along the front-rear direction X of the vehicle. The recessed portion 51 is recessed toward the opposite side to the sliding body 7 side. In other words, the recessed portion 51 is recessed toward the outer side of the vehicle along the vehicle width direction Y. The recessed portion 51 is configured corresponding to the moving range of the sliding member 70. The recessed portion 51 is opposite to the supporting portion 72 in the vehicle width direction Y. That is, the rotation axis of the seat cushion 8 is opposite to the recessed portion 51. An opening portion 52 for leading out the wiring harness 2 is provided in the recessed portion 51. The opening portion 52 connects the space inside the vehicle than the interior component 5 and the space outside the vehicle than the interior component 5 along the vehicle width direction Y. The armrest 73 is connected to the sliding member 70. The armrest 73 covers the sliding member 70, for example, from the upper side of the vehicle up-down direction H.

As shown in FIG. 1 and other figures, the winding device 3 is arranged outside the vehicle with respect to the interior part 5. The winding device 3 is arranged, for example, at a position opposite to the recessed portion 51. The winding device 3 is fixed to the vehicle body 100. As shown in FIG. 5, the winding device 3 includes a main body 30, a cylindrical portion 31, and a lead-out portion 32. The main body 30, the cylindrical portion 31, and the lead-out portion 32 are formed of, for example, an insulating synthetic resin.

The main body 30 is a frame that accommodates the wire harness 2. The shape of the main body 30 is, for example, a cylindrical shape with both ends of the axial direction closed. A winding mechanism for winding the wire harness 2 is arranged inside the main body 30. The winding mechanism includes, for example, a rotating body and a spring around which the wire harness 2 is wound. The winding device 3 can wind the wire harness 2 and extract the wire harness 2 using the winding mechanism.

The cylindrical portion 31 is formed in a cylindrical shape and extends from the main body 30. The opening 31a of the cylindrical portion 31 is open in the vehicle width direction Y. The wire harness 2 is led out from the inside of the main body 30 through the cylindrical portion 31. The winding device 3 is arranged in a manner that the opening 31a and the opening portion 52 of the interior component 5 are opposite. Therefore, the wire harness 2 led out from the opening 31a is inserted into the opening portion 52 along the vehicle width direction Y. The lead-out portion 32 is an outlet portion for leading out the electric wires on the vehicle body side. The electric wires on the vehicle body side are electrically connected to the wire harness 2 inside the main body 30. The electric wires on the vehicle body side are led out from the lead-out portion 32 and connected to a power source and a control device.

As shown in FIG6 , a holding member 4 is provided on the sliding body 7. The holding member 4 is a member that holds the wire harness 2 and moves along the vehicle front-rear direction X together with the sliding body 7. The holding member 4 of this embodiment is fixed to the armrest 73. A portion of the holding member 4 protrudes from the side surface 73a of the armrest 73 toward the vehicle width direction Y. The wire harness 2 is inserted into the internal space of the armrest 73 via the holding member 4 and is held by the holding member 4.

As shown in Fig. 7 and Fig. 8, the holding member 4 has a main body 40 and a cover 41. The main body 40 and the cover 41 are formed of, for example, an insulating synthetic resin. As shown in Fig. 8, the main body 40 has a bottom wall 42, a first side wall 43, and a second side wall 44. The bottom wall 42, the first side wall 43, and the second side wall 44 are formed as one body. The bottom wall 42, the first side wall 43, and the second side wall 44 form a passage 45 of the wiring harness 2. The bottom wall 42 is a wall portion that supports the wiring harness 2 from below.

The first side wall 43 and the second side wall 44 stand up from the edge of the bottom wall 42 and face each other in the vehicle front-rear direction X. The first side wall 43 has a straight portion 43a and a curved portion 43b. The straight portion 43a extends in a straight line along the vehicle width direction Y. The base end 43c of the curved portion 43b is connected to the straight portion 43a. The curved portion 43b is curved in a manner that moves away from the second side wall 44 as it moves from the base end 43c of the curved portion 43b toward the top end 43d.

The second side wall 44 has a straight portion 44a and a curved portion 44b. The straight portion 44a extends straight along the vehicle width direction Y. The straight portion 44a is opposite to the straight portion 43a of the first side wall 43 and is parallel to the straight portion 43a. The base end 44c of the curved portion 44b is connected to the straight portion 44a. The curved portion 44b is curved in a manner that moves away from the first side wall 43 as it moves from the base end 44c of the curved portion 44b toward the top end 44d.

Thus, the first side wall 43 and the second side wall 44 are tapered so that the interval between the curved portions 43b and 44b increases toward the top ends 43d and 44d of the curved portions 43b and 44b. Therefore, the width of the passage 45 increases toward the end 45a in the vehicle width direction Y.

The cover 41 is a member that engages with the main body 40 and covers the channel 45 from the upper side. The cover 41 includes a covering portion 46 and an engaging portion 47. The covering portion 46 and the engaging portion 47 are formed as one body. The covering portion 46 is a portion that covers the channel 45 from the upper side. The covering portion 46 includes a rectangular portion 46a and a tapered portion 46b. The rectangular portion 46a is substantially rectangular in shape when viewed from above. The rectangular portion 46a is formed to cover the range from the straight portion 43a of the first side wall 43 to the straight portion 44a of the second side wall 44.

The shape of the tapered portion 46b when viewed from above is a tapered shape whose width increases as it moves away from the rectangular portion 46a in the vehicle width direction Y. The tapered portion 46b is formed to cover the range from the curved portion 43b of the first side wall 43 to the curved portion 44b of the second side wall. The engaging portion 47 engages with the main body 40 to fix the cover 41 to the main body 40. The cover 41 has a holding portion 49 that holds the wire harness 2. The holding portion 49 protrudes from the covering portion 46 in the vehicle width direction Y.

The retaining member 4 has a cylindrical portion 48 formed by a main body 40 and a cover 41. As shown in FIG. 7 , the width W1 of the cylindrical portion 48 in the vehicle front-rear direction X increases as it moves toward the opening 48a along the vehicle width direction Y. The wire harness 2 is inserted into the cylindrical portion 48 and is retained by the retaining member 4. The wire harness 2 is fixed to the retaining portion 49, for example, using a belt or a strap component. That is, the retaining portion 49 retains the wire harness 2 via the belt or the strap component. The wire harness 2 may also be retained by being clamped between the bottom wall 42 of the main body 40 and the rectangular portion 46a of the cover 41. In this case, at least one of the bottom wall 42 and the cover 41 may also have a protrusion or a rib for pressing the wire harness 2.

The holding member 4 is arranged so that the opening 48a faces the recessed portion 51 of the interior member 5. That is, the tubular portion 48 is arranged so that the width W1 in the vehicle front-rear direction X increases as it approaches the interior member 5 along the vehicle width direction Y. The tubular portion 48 has a curved shape that does not cause excessive bending stress to be generated in the wire harness 2.

9 to 11 show the sliding seat 10 and the wiring harness 2 in the unfolded state. The position of the sliding seat 10 shown in FIG. 9 and the like is the rearmost position in the movable range in the vehicle front-rear direction X. In the following description, regarding the position of the sliding seat 10, the rearmost position in the movable range is referred to as the "rear end position", and the frontmost position in the movable range is referred to as the "front end position". At the rear end position, as shown in FIG. 10, the retaining component 4 is opposite to the opening portion 52 in the vehicle width direction Y. That is, in the vehicle width direction Y, the opening portion 52 is coaxial with the cylindrical portion 48 of the retaining component 4. The top end 48b of the retaining component 4 is located on the same surface as the wall surface 5b of the interior component 5. Therefore, the retaining component 4 can shield the wiring harness 2 from the occupant, making the wiring harness 2 inconspicuous.

As shown in FIGS. 9 to 11, the wire harness 2 led out from the winding device 3 is inserted through the interior part 5 toward the vehicle interior. As shown in FIG. 9, the interior part 5 has a cylindrical portion 53 protruding toward the vehicle width direction Y. The cylindrical portion 53 protrudes toward the cylindrical portion 31 of the winding device 3. The opening 52 is provided at the top end of the cylindrical portion 53. The shape of the cylindrical portion 53 when viewed from above is a tapered shape in which the width in the vehicle front-rear direction X becomes smaller as it moves toward the cylindrical portion 31 along the vehicle width direction Y.

As shown in FIG. 10 , the wire harness 2 is led out from the opening portion 52 toward the vehicle interior via the recessed portion 51. The wire harness 2 that passes through the interior component 5 is inserted into the cylindrical portion 48 of the retaining component 4, and is then laid out in the space inside the armrest 73. As shown in FIG. 9 , the end of the wire harness 2 is fixed to the fixing portion 80 of the seat cushion 8. Each wire of the wire harness 2 is connected to a device disposed on the sliding seat 10. The end of each wire can also be connected to a connector. In this case, each wire is connected to the device of the sliding seat 10 via a connector.

As shown in FIG. 9 , the wiring path of the wire harness 2 in the sliding seat 10 is bent. More specifically, the wire harness 2 includes a first portion 21, a second portion 22, and a bent portion 23. The first portion 21 is a portion extending from the retaining member 4 toward the seat cushion 8 in the vehicle width direction Y. The second portion 22 is a portion extending in the vehicle front-rear direction X and fixed to the seat cushion 8. The bent portion 23 connects the first portion 21 and the second portion 22.

The holding member 4 holds the first portion 21 so that the first portion 21 extends along the vehicle width direction Y. As shown in FIG. 11 , the first portion 21 of the present embodiment extends parallel to the vehicle width direction Y. The fixing portion 80 holds the second portion 22 so that the second portion 22 extends along the vehicle front-rear direction X. The fixing portion 80 is, for example, arranged in front of the vehicle with respect to the first portion 21. In this case, the second portion 22 extends from the curved portion 23 toward the front of the vehicle. The second portion 22 of the present embodiment extends parallel to the vehicle front-rear direction X.

As shown in Fig. 9 , when the sliding seat 10 is in the expanded state, the shape of the curved portion 23 in a plan view is substantially an arc shape. The shape of the curved portion 23 is determined so as not to generate excessive bending stress on each electric wire of the wire harness 2 .

FIG. 12 shows the sliding seat 10 at the front end position. When the sliding seat 10 slides forward in the vehicle front-rear direction X, the holding member 4 moves forward together with the armrest 73. The holding member 4 moves forward while holding the wire harness 2, and the wire harness 2 is led out from the winding device 3. The led-out wire harness 2 extends inside the recess 51 of the interior member 5 along the vehicle front-rear direction X. Therefore, the led-out wire harness 2 is difficult to be seen from the occupant, and the wire harness 2 is not easy to interfere with the armrest 73 and the like.

As shown in FIG. 12 , the wire harness 2 includes a first portion 26 and a second portion 27. The first portion 26 and the second portion 27 are formed between the sliding seat 10 and the opening 52 of the interior 5. The first portion 26 is a portion that protrudes from the cylindrical portion 48 toward the recess 51 along the vehicle width direction Y. The second portion 27 is a portion that extends from the recess 51 along the vehicle front-rear direction X. A curved portion 28 is formed between the first portion 26 and the second portion 27. The wire harness 2 of this embodiment includes the first portion 26, and follows the movement of the sliding seat 10 while forming the second portion 27.

The second portion 27 of the present embodiment extends from a position 51a in the recess 51 that is opposite to the cylindrical portion 48 to the opening 52. As a mechanism for extending the second portion 27 in the recess 51, for example, the holding member 4 holds the wire harness 2. In the holding member 4, the wire harness 2 protrudes the cylindrical portion 48 toward the recess 51. In addition, the holding member 4 holds the wire harness 2 in a manner that presses the wire harness 2 against the bottom surface 51b of the recess 51. The wire harness 2 pressed toward the bottom surface 51b forms the second portion 27 and the curved portion 28, and extends in the recess 51.

As a mechanism for extending the second portion 27 in the recessed portion 51, a curved portion 53a is provided in the cylindrical portion 53 of the interior member 5. The curved portion 53a is curved so that the width of the cylindrical portion 53 increases as it approaches the sliding seat 10 in the vehicle width direction Y. A curved portion 29 that is curved along the curved portion 53a is formed in the wire harness 2. The curved portion 53a of the cylindrical portion 53 guides the wire harness 2 inserted from the opening 52 to the bottom surface 51b. Therefore, the second portion 27 of the wire harness 2 can extend along the bottom surface 51b.

When the sliding seat 10 slides rearward, the winding device 3 winds up the excess length of the wire harness 2. That is, the winding device 3 applies tension to the wire harness 2 extending in the recess 51. Thus, the wire harness 2 can follow the movement of the sliding seat 10 while the second portion 27 is extended in the recess 51.

13 and 14 show the sliding seat 10 and the harness 2 in a pop-up state. The sliding seat 10 of the present embodiment is configured to be able to pop up at a rear end position. As shown in FIG. 13 , in the pop-up state, the fixing portion 80 of the seat cushion 8 is located above the first portion 21 in the vehicle vertical direction H. That is, the seat cushion 8 is relatively rotated relative to the slider 70 in such a manner that the fixing portion 80 moves upward relative to the first portion 21.

When the seat cushion 8 is popped up, the fixing portion 80 moves upward while bending the first portion 21 of the wire harness 2. As a result, the second bent portion 24 is formed in the first portion 21. That is, in the popped-up state, the second bent portion 24 is formed on the wire harness 2 in addition to the bent portion 23. The wiring structure 1 for a sliding seat is preferably constructed so that it is not easy to generate axial stress on the wire harness 2 when it is popped up. For example, the rotating mechanism that rotates the seat cushion 8 is preferably constructed so that it is not easy to generate tensile stress on the first portion 21 when the seat cushion 8 rotates. For example, at least one of the armrest 73 and the seat cushion 8 may also have a space portion that allows the wire harness 2 to be bent and deformed. For example, a space portion may also be provided around the portion where the second bent portion 24 is formed in a manner that does not constrain the wire harness 2.

The above-mentioned wiring structure 1 for a sliding seat can make the wire harness 2 follow the movement of the sliding seat 10 along the vehicle front-rear direction X. Furthermore, the wiring structure 1 for a sliding seat can make the wire harness 2 follow the pop-up of the seat cushion 8. Thus, the wiring structure 1 for a sliding seat can make the wire harness 2 appropriately follow the sliding seat 10 with a pop-up mechanism.

In addition, by providing the wire harness 2 with the bent portion 23, it is possible to reduce the bending load on each electric wire of the wire harness 2. By providing the wire harness 2 with the bent portion 23, the wire harness composed of a plurality of electric wires is allowed to twist when forming the second bent portion 24. As a result, the bending load on each electric wire is reduced compared to a case where the wire harness 2 does not have the bent portion 23.

As described above, the wiring structure 1 for a sliding seat according to the present embodiment includes: a recessed portion 51 provided in the interior member 5 constituting the side wall of the vehicle compartment; an opening portion 52 disposed in the recessed portion 51; a cylindrical portion 48; a wire harness 2; and a winding device 3. The recessed portion 51 extends in the vehicle front-rear direction X and is recessed toward the vehicle outer side. The opening portion 52 connects a space on the vehicle outer side than the interior member 5 with a space on the vehicle inner side than the interior member 5.

The cylindrical portion 48 is disposed on the sliding seat 10 that slides along the interior 5 in the vehicle front-rear direction X. The cylindrical portion 48 is opposed to the recessed portion 51 and opens toward the recessed portion 51. The wire harness 2 is inserted into the cylindrical portion 48 from the opening 52 via the recessed portion 51 and connected to the sliding seat 10. According to the wiring structure 1 for the sliding seat involved in this embodiment, by routing the wire harness 2 in the recessed portion 51, it is possible to prevent the wire harness 2 from interfering with the sliding seat 10.

The wire harness 2 of the present embodiment has a first portion 26 protruding from the cylindrical portion 48 toward the recess 51 along the vehicle width direction Y, and follows the movement of the sliding seat 10 while forming a second portion 27 extending in the recess 51 along the vehicle front-rear direction X. For example, in the present embodiment, the wire harness 2 is held by the holding member 4. The wire harness 2 protrudes from the cylindrical portion 48 toward the recess 51 in the vehicle width direction Y, and abuts against the bottom surface 51b of the recess 51 to be bent toward the vehicle front-rear direction X. Thus, the first portion 26 protruding from the cylindrical portion 48 toward the recess 51 and the second portion 27 extending in the recess 51 along the vehicle front-rear direction X are formed.

The second portion 27 of the present embodiment extends from a position 51a of the recessed portion 51 that faces the cylindrical portion 48 to the opening 52. Therefore, the wire harness 2 is less likely to interfere with the sliding seat 10.

The sliding seat 10 of the present embodiment includes an armrest 73 facing the recessed portion 51. The cylindrical portion 48 is fixed to the armrest 73. By arranging the recessed portion 51 at a position facing the armrest 73, the recessed portion 51 is covered by the armrest 73 and is not easily visible.

The tip 48b of the cylindrical portion 48 of the present embodiment protrudes from the sliding seat 10 toward the recessed portion 51. According to this structure, the path of the wire harness 2 is stabilized, and the wire harness 2 is unlikely to escape from the recessed portion 51 to the outside.

The shape of the cylindrical portion 48 of the present embodiment is a tapered shape in which the width W1 in the vehicle front-rear direction X increases toward the recessed portion 51 along the vehicle width direction Y. This can reduce the bending load applied to the wire harness 2.

[First Modification of Embodiment]

A first variant of the embodiment will be described. FIG. 15 is a perspective view of a wiring structure for a sliding seat according to the first variant of the embodiment, and FIG. 16 is a top view of a wiring structure for a sliding seat according to the first variant of the embodiment. The first variant of the embodiment is different from the above-described embodiment in that, for example, the winding device 3 is disposed on the sliding seat 10.

As shown in FIGS. 15 and 16 , the wiring structure 1 for a sliding seat according to the first variant of the embodiment includes: a recess 51 provided in the interior member 5 ; an opening 52 arranged in the recess 51 ; a cylindrical portion 6 arranged in the sliding seat 10 ; a wire harness 2 ; and a winding device 3 .

The winding device 3 is disposed on the seat cushion 8 of the sliding seat 10. The winding device 3 can be housed inside the seat cushion 8. The wire harness 2 protrudes from the winding device 3 in the vehicle width direction Y. The winding device 3 can wind the wire harness 2 and unwind the wire harness 2.

The cylindrical portion 6 is a cylindrical component and is arranged on the sliding seat 10. The cylindrical portion 6 is opposite to the recessed portion 51 in the vehicle width direction Y and is open toward the recessed portion 51. The shape of the cylindrical portion 6 is a tapered shape in which the width in the vehicle front-rear direction X increases toward the recessed portion 51 along the vehicle width direction Y. The wire harness 2 of the first modified example is not fixed to the cylindrical portion 6. In other words, the cylindrical portion 6 does not hold the wire harness 2 and allows the wire harness 2 to pass freely.

An opening 52 is disposed in the recess 51. The opening 52 is disposed, for example, at the center of the recess 51 in the vehicle front-rear direction X. The sliding seat 10 is configured so that the seat cushion 8 can be flipped up at a position where the cylindrical portion 6 and the opening 52 face each other.

The wire harness 2 is inserted into the cylindrical portion 6 through the recess 51 from the opening 52 and connected to the sliding seat 10. As shown in FIG16, the interior component 5 has a retaining member 55. The retaining member 55 is arranged at the opening 52. The retaining member 55 has a cylindrical portion 56 and a retaining portion 57. The cylindrical portion 56 and the retaining portion 57 are formed of, for example, insulating synthetic resin.

The cylindrical portion 56 is cylindrical in shape and extends in the vehicle width direction Y. One end of the cylindrical portion 56 opens toward the opening portion 52. The wire harness 2 is inserted into the cylindrical portion 56 from the opening portion 52 along the vehicle width direction Y. The retaining portion 57 protrudes from the other end of the cylindrical portion 56. The wire harness 2 is fixed to the retaining portion 57 by a belt or a tie member. The wire harness 2 drawn out from the cylindrical portion 56 is connected to a power source and a control device.

Similar to the wire harness 2 of the above-mentioned embodiment, the wire harness 2 of the first modified example follows the movement of the sliding seat 10 along the vehicle front-rear direction X. The wire harness 2 follows the movement of the sliding seat 10 while forming the second portion 27 extending in the recess 51. For example, when the sliding seat 10 moves toward the rear end position, as shown in FIG. 12, the wire harness 2 forms the second portion 27 from the retaining member 55 toward the rear of the vehicle. The second portion 27 extends in the recess 51 along the vehicle front-rear direction X. The winding device 3 delivers the wire harness 2 or winds the wire harness 2 in accordance with the movement of the sliding seat 10.

[Second Modification of Embodiment]

17 is a cross-sectional view of a wiring structure for a sliding seat according to a second modification of the embodiment. The second modification of the embodiment is different from the above-described embodiment in that the tip 48b of the cylindrical portion 48 is inserted into the recess 51.

As shown in FIG. 17 , the top end 48b of the cylindrical portion 48 of the second modified example is located inside the recess 51. That is, the top end 48b of the cylindrical portion 48 moves in the internal space of the recess 51 in the vehicle front-rear direction X. With such a structure, the wire harness 2 is not easily removed from the recess 51. In addition, the first portion 26 of the wire harness 2 is covered by the cylindrical portion 48, so that the wire harness 2 is not easily noticeable. In addition, in the wiring structure 1 for a sliding seat involved in the above-mentioned first modified example, the top end 6a of the cylindrical portion 6 may be inserted into the recess 51.

[Third Modification of Embodiment]

The shape and arrangement of the holding member 4 and the cylindrical portion 6 are not limited to the illustrated shape and arrangement. For example, the sliding seat 10 may not have a pop-up mechanism. In this case, the holding member 4 and the cylindrical portion 6 may be arranged on the seat cushion 8. The recessed portion 51 of the interior member 5 may also be provided at a position opposite to the seat cushion 8.

The contents disclosed in the above-mentioned embodiments and modifications can be implemented in combination as appropriate.
