It is not limited to. For example, the protection part and the vehicle body fixing part may be integrally formed. That is, a configuration including a protection portion that covers the outer peripheral portion of the wire harness 42 and a vehicle body fixing portion that is continuously provided on the vehicle body 10 side of the protection portion and can be fixed to the vehicle body hole 11 of the vehicle body 10 is adopted. be able to.

<Protector>
The protector 60 is a part that accommodates the wire harness 42 that is advanced and retracted in the door 20 in accordance with the opening / closing operation of the door 20 so as to be able to absorb the extra length and protects it from the outside (see FIGS. 8 to 11). The protector 60 is disposed in the door 20 between the door trim 26 and the door inner panel 22 outside the vehicle compartment from the door trim 26 (see FIGS. 5 and 6). The protector 60 includes an insertion port portion 62 and a surplus length absorbing portion 64. Hereinafter, the protector 60 may be described using the front-rear direction and the vertical direction in a state where the protector 60 is disposed on the door 20 (see FIG. 1). The front-rear direction of the door 20 is the front-rear direction in the closed state of the door 20, and substantially coincides with the front-rear direction of the vehicle.

  The insertion port portion 62 is a portion that opens in front of the door 20 and into which the wiring portion 40 is inserted (see FIGS. 2 and 3). Here, a portion including the end portion on the door 20 side of the protection portion 44 is inserted into the insertion port portion 62. The insertion port 62 is formed in a cylindrical shape. More specifically, the insertion port 62 is formed in a substantially rectangular shape (here, each corner is rounded) in a cross-sectional view orthogonal to the central axis. And the insertion port part 62 restrict | limits the movement of the wiring part 40 (mainly protection part 44) inserted inside in the direction orthogonal to a central axis, and guides it to the surplus length absorption part 64 side.

  Further, the insertion port portion 62 is formed in a shape that gradually expands toward the vehicle exterior side as the wall portion outside the vehicle interior approaches the opening end (see FIGS. 5 and 6). According to such a shape of the insertion port portion 62, the advance / retreat operation of the protection portion 44 into the protector 60 becomes smoother.

  The protector 60 aligns the central axis of the insertion port 62 along the front-rear direction of the door 20 (although it may be tilted within a range that does not hinder the smooth advancement and retraction operation of the wiring unit 40). It is arranged in the door 20 in a posture that opens toward the front of the door 20. FIG. 1 shows an example in which the protector 60 is disposed at a position below the speaker 90. The protector 60 is set to have a shape and a size that fit within a region on the door inner panel 22 side from the vehicle interior side end of the speaker 90 (see FIGS. 5 and 6). Further, the protector 60 is disposed so that the insertion opening 62 is located inside (or behind) the introduction opening 21 of the door 20.

  The surplus length absorbing portion 64 is a portion that accommodates an extra space that can be bent by bending the wire harness 42 that extends from the end of the protective portion 44 on the door 20 side (see FIGS. 2 to 4). The extra length absorbing portion 64 is formed continuously behind the insertion port portion 62. The surplus length absorbing portion 64 has an accommodation space including a margin space communicating with the internal space of the insertion port portion 62 inside thereof. Further, the surplus length absorbing portion 64 has an outlet portion 68 through which the wire harness 42 inserted through the insertion port portion 62 is pulled out into the door 20.

  The surplus length absorbing portion 64 is accommodated by bending the wire harness 42 of the wiring portion 40 between the first route R1 and the second route R2 bulging and detouring with respect to the first route R1 in the accommodation space. It is made possible. More specifically, the surplus length absorbing portion 64 has a first wall portion 641, a second wall portion 642, and a third wall that surround the accommodation space in a side view (as seen from the side as seen from the vehicle interior side). A portion 643 is included. The first route R1 is a route along the second wall portion 642, and the second route R2 is a route along the first wall portion 641 and the third wall portion 643. Hereinafter, the shape in the side view of the 1st wall part 641, the 2nd wall part 642, and the 3rd wall part 643 is demonstrated.

  The first wall portion 641 is a wall portion that continues to the upper wall portion of the insertion port portion 62 and extends in the front-rear direction of the door 20 at a position above the accommodation space. The wall portion extending from the insertion port portion 62 formed of the upper wall portion of the insertion port portion 62 and the first wall portion 641 to the surplus length absorption portion 64 includes a retracting portion 644 that swells upward. The retracting portion 644 is provided in a portion on the rear side of the door 20 in the front-rear direction with respect to the position of the end portion on the door 20 side of the protection portion 44 in the opened state of the door 20. Here, the retracting portion 644 is continuous with a part of the first wall portion 461, more specifically, behind the upper wall portion of the insertion port portion 62, and a portion above the position of the outlet portion 68 described later. It is provided over the range to include.

  The second wall portion 642 is a wall portion that continues to the lower wall portion of the insertion port portion 62 and extends rearward and downward. That is, the second wall portion 642 extends to the front and lower position of the accommodation space. More specifically, the second wall portion 642 is formed in a shape extending from the rear end portion of the insertion port portion 62 rearward along the front-rear direction of the door 20 and curved in the middle and extending downward along the vertical direction. Has been.

  The third wall portion 643 is a wall portion that is continuous with the rear end portion of the first wall portion 641 and bulges backward and then extends downward and forward. That is, the third wall portion 643 extends to a position behind and below the accommodation space. More specifically, the third wall portion 643 extends downward from the rear end portion of the first wall portion 641 while slightly inflating backward, and extends downward along the vertical direction, and then tilts forward and downward therefrom. It is formed in a shape extending (or curved).

  That is, the third wall portion 643 is provided at a site on the rear side of the door 20 with respect to the insertion port portion 62, and the wire harness 42 that is entered in accordance with the closing operation of the door 20 is disposed on the lower side and on the front side of the door 20. It constitutes a rear wall that can be bent. Then, when the door 20 is closed, the wire harness 42 that enters the surplus length absorbing portion 64 through the insertion port portion 62 is bent and deformed along the third wall portion 643 and contacts the third wall portion 643. In the case of contact, bending is regulated along this shape.

  In addition, the third wall portion 643 is a rear portion of the surplus length absorbing portion 64 from the viewpoint of reducing the load applied to the bundled electric wires 43 of the wire harness 42 that is bent and deformed with the closing operation of the door 20. In this case, it is preferable that the first wall portion 641 is set to have a shape with a gap as large as possible. Further, the rear end portion of the third wall portion 643 is located behind the position of the end portion on the door 20 side of the protective portion 44 that enters the surplus length absorbing portion 64 in the closed state of the door 20, and The interval may be set to be larger than the bending radius of the bundled electric wires 43 of the wire harness 42 or larger.

  The lower end portion of the second wall portion 642 and the lower end portion of the third wall portion 643 exist with a gap in the front-rear direction of the door 20, and the portion that forms this gap is the outlet portion 68. That is, the outlet portion 68 is set at a position that is shifted in the vertical direction (downward here) with respect to the insertion port portion 62. The outlet portion 68 is set so as to open downward (here, downward along the vertical direction).

  The outlet portion 68 has a harness fixing portion 69 whose opening edge extends partially (here, in a substantially L shape) (see FIGS. 2 and 10). The harness fixing portion 69 includes a flat portion that extends along a direction orthogonal to the front-rear direction of the door 20. Here, the harness fixing portion 69 includes a portion extending downward from the lower end portion of the second wall portion 642 as the flat portion.

  Then, in a state where the wire harness 42 is aligned with the outlet portion 68, the wire harness 42 is bundled together with the outlet portion 68 by the binding member 96, so that a part of the wire harness 42 is connected to the outlet portion 68. Fixed. Thereby, the wire harness 42 can be prevented from being pulled out of the protector 60 or being drawn into the protector 60 in accordance with the opening / closing operation of the door 20, and the extra length can be absorbed more smoothly. As the binding member 96, an adhesive tape, a binding band, a string, a wire, or the like can be used.

  Further, the insertion port portion 62 and the outlet portion 68 of the protector 60 are set at positions shifted from the door 20 toward the outside of the vehicle interior. Here, the outlet portion 68 is set at a position on the vehicle interior side of the door 20 with respect to the insertion port portion 62. The surplus length absorbing portion 64 extends from the insertion port portion 62 side to the outlet port portion 68 side in the exterior of the door as it goes from the insertion port portion 62 side to the outlet port 68 side in the vertical direction of the door 20. The site | part formed in the shape which moves gradually toward is included. Here, a part of the extra length absorbing portion 64 is formed in a shape that gradually moves downward toward the vehicle interior side of the door 20.

  More specifically, the curved portion and the portion extending downward of the second wall portion 642 extend while shifting from the vehicle interior side to the vehicle interior side. In addition, a portion of the third wall portion 643 that extends downward and forward extends while shifting from the vehicle interior side to the vehicle interior side. In other words, at least a part of the pair of wall portions opposed to each other in the vehicle interior / exterior direction of the extra length absorption portion 64 is inclined (or from the insertion port portion 62 side to the outlet portion 68 side) in the vehicle interior / exterior direction (or A curved shape. The surplus length absorbing portion 64 causes the pair of wall portions to direct the wire harness 42 routed in the surplus length absorbing portion 64 from the insertion port portion 62 side to the outlet port portion 68 side in the vehicle interior and exterior direction. Are restricted to the path of transition. Preferably, the surplus length absorbing portion 64 is formed in a shape having a pair of wall portions capable of gradually guiding the wire harness 42 in a closed state of the door 20 to a route toward the outlet portion 68 side in the vehicle interior / exit direction. It is good to be.

  And in the open state of the door 20, the protection part 44 has evacuated from the inside of the surplus length absorption part 64, and the wire harness 42 is the 1st path | route bent along the 2nd wall part 642 in the accommodation space. It is routed through R1 (see FIG. 3). At this time, there is a margin space on the side of the first wall portion 641 and the third wall portion 643 of the wire harness 42 passing through the first route R1.

  When the door 20 is closed from the open state, the protection part 44 is inserted into the extra length absorption part 64 toward the rear of the door 20 (see FIG. 4). At this time, a portion of the wire harness 42 near the pull-out port portion 68 extends in the vertical direction of the door 20, and tries to push the portion closer to the vehicle body 10 upward by its own rigidity. As a result, the end of the protective portion 44 on the door 20 side is pushed upward when entering the surplus length absorbing portion 64, and the upper portion is located inside the retracting portion 644 of the first wall portion 641. Pass through space.

  And as the protection part 44 enters the surplus length absorption part 64, the wire harness 42 extended from the door 20 side end part of the protection part 44 is bent downward and forward from the form bent downward. It will change to the form that was made. That is, the wire harness 42 extended from the end portion on the door 20 side of the protection portion 44 gradually approaches the third wall portion 643. When the door 20 is in a closed state, a portion of the wire harness 42 that extends from the end of the protective portion 44 on the door 20 side is bent along the third wall portion 643 and arranged through the second path R2. It is searched (see FIG. 2).

  Thus, the extra length of the wire harness 42 accompanying the closing operation of the door 20 can be absorbed by bending the wire harness 42 and changing the path to the second path R2 longer than the first path R1. Further, when the door 20 is opened from the closed state, the protective portion 44 is retracted from the surplus length absorbing portion 64, and the wire harness 42 is bent along the second wall portion 642 from the second path R2. The route is changed to the first route R1.

  Here, the attachment structure with respect to the door 20 of the protector 60 is demonstrated. The protector 60 is formed so as to be attachable by pressing it against the door inner panel 22 of the door 20 toward the outside of the passenger compartment. Here, the protector 60 has the fixing | fixed part 78 which can be fitted with respect to the hole formed in the door inner panel 22 (refer FIG. 5, FIG. 6). For example, the fixing portion 78 includes a base shaft portion that protrudes from the outer end surface of the passenger compartment on the outer surface of the protector 60 (herein, a first member 601 described later), and a disc spring-like shape that projects from the base end portion to the outer peripheral side. A structure having a pressing portion and a locking portion which is provided so as to protrude from the distal end portion of the base shaft portion toward the outer peripheral side and can be elastically deformed toward the inner peripheral side can be employed. That is, by inserting the fixing portion 78 from the vehicle interior side toward the vehicle exterior side with respect to the hole portion, the locking portion comes into contact with the peripheral edge portion of the hole portion and elastically deforms toward the inner peripheral side. If it exceeds the part, it will be elastically restored to the outer peripheral side and locked to the opening edge of the hole from the outside of the passenger compartment. Further, the presser portion is locked from the vehicle interior side with respect to the peripheral edge portion of the hole portion. In addition, the protector 60 may be fixed to the door inner panel 22 by screwing or the like, or may be fixed to the door trim 26.

  The protector 60 described above may be configured by combining a first member 601 and a second member 602 (see FIGS. 9 to 11). For example, as the first member 601 and the second member 602, a combination of a concave member and a lid member divided in the vehicle interior / exterior direction of the door 20, a combination of a pair of concave members, or the like can be employed. And the protector 60 can obtain the 1st member 601 and the 2nd member 602 by pouring a synthetic resin material into a metal mold, injection molding, and combining them. The first member 601 and the second member 602 are preferably formed so that a plurality of locked portions or locking portions are provided in the vicinity of the butt end portion of each member so that the combined state can be maintained.

<Wiring harness layout in the protector>
In the wire harness routing structure 30, in order to reduce the load applied to the wire harness 42 due to the opening / closing operation of the door 20, the wire harness 42 is twisted in a bundle of a plurality of electric wires 43 in the protector 60. It is routed (see Fig. 2 and Fig. 3). Hereinafter, the twist form of the wire harness 42 will be described.

  In the wire harness 42, at least a part of a portion that is bent and deformed in the surplus length absorbing portion 64 in accordance with the opening / closing operation of the door 20 is routed in a form in which a plurality of bundled electric wires 43 are twisted. Here, in the wire harness 42, a plurality of bundle-shaped electric wires 43 are twisted in a range extending from the end portion on the door 20 side of the protective portion 44 to the outlet portion 68. The twisted form of the bundle-like electric wires 43 is determined by the form of the bundle-like electric wires 43 in the end part on the door 20 side of the protection part 44 and the outlet part 68. That is, the postures of the bundled electric wires 43 around the virtual axis along the extending direction of the wire harness 42 are different between the end portion on the door 20 side of the protection portion 44 and the form in the outlet portion 68.

  Here, the wire harness 42 is held in a flat shape at a portion where a plurality of bundled electric wires 43 extend from an end portion of the protective portion 44 on the door 20 side. More specifically, since the protection part 44 has a flat shape along the vertical direction, the plurality of bundled electric wires 43 in the wire harness 42 extending from the end on the door 20 side are flattened on the protection part 44. The flat shape corresponding to the various outlet shapes is maintained. That is, the plurality of bundled electric wires 43 are held in a flat shape along the vertical direction. However, the plurality of bundle-shaped electric wires 43 may be fixed to the flat shape by tape-wrapping the end portion on the door 20 side of the protective portion 44 so that the flat shape is more reliably maintained. . In the wire harness 42, a plurality of bundled electric wires 43 are held in a flat shape by the outlet portion 68. More specifically, the harness fixing portion 69 of the outlet portion 68 is formed in a flat shape along a direction orthogonal to the front-rear direction of the door 20 (see FIGS. 2 and 10). The wire harness 42 is fixed to the harness fixing portion 69 by a binding member 96 in a form in which a plurality of electric wires 43 are arranged along the rear surface of the door 20. Therefore, the plurality of bundle-shaped electric wires 43 are held in a flat shape along the flat harness fixing portion 69 along the vertical direction of the door 20 and the outside of the vehicle interior.

  Further, the twisting direction of the plurality of bundled electric wires 43 is drawn from the insertion port portion 62 side (vehicle compartment outer side) in the vehicle interior / exterior direction of the door 20 as viewed from the extending direction of the wire harness 42 (vehicle body 10 side). It is set to turn around (to the right) toward the exit 68 (the vehicle interior side). That is, a portion of the wire harness 42 from the end on the door 20 side of the protective portion 44 to the outlet portion 68 is bent from the insertion port portion 62 side toward the outlet portion 68 side in the vehicle interior / exterior direction. While twisted. This twist direction is set corresponding to the configuration of the protector 60 in which the outlet portion 68 is located on the vehicle interior side of the door 20 with respect to the insertion port portion 62. In this case, the plurality of bundle-like electric wires 43 extend while being twisted by approximately 90 degrees in a flat shape between the end portion on the door 20 side of the protection portion 44 and the outlet portion 68 (harness fixing portion 69). doing. More specifically, the plurality of bundled electric wires 43 are twisted mainly at a position on the rear side of the end portion of the protective portion 44 on the door 20 side. That is, the wire harness 42 is bent mainly in the thickness direction of the plurality of bundle-shaped electric wires 43 extending in a flat shape, and the portion near the outlet portion 68 extends in a flat shape along the outside of the vehicle interior. doing.

  According to the wire harness wiring structure portion 30 according to the first embodiment, the wire harness 42 in the wiring portion 40 partially fixed to the vehicle body 10 is from the insertion port portion 62 of the protector 60 disposed in the door 20. It is inserted and stored in a surplus space that can be bent and detoured in the extra length absorbing portion 64 of the protector 60 and pulled out from the outlet portion 68. This wire harness 42 is routed in a form in which at least a part of a portion bent in the extra length absorbing portion 64 is twisted by unbundling a plurality of bundled electric wires 43. For this reason, each electric wire 43 in the plurality of electric wires 43 of the wire harness 42 is bent on the inner peripheral side or the outer peripheral side when the wire harness 42 enters and is bent into the accommodating portion with the closing operation of the door 20. It extends without bias. Thereby, the compression and expansion | extension load concerning each electric wire 43 by the difference of the extension distance of the inner peripheral side in the bending form of the wire harness 42 and the extension distance of an outer peripheral side are reduced. And the load concerning the wire harness 42 bent and deformed with the opening / closing operation | movement of the door 20 can be reduced.

  Further, the insertion port portion 62 and the outlet port portion 68 are set at positions shifted in the vehicle interior / exterior direction and the vertical direction of the door 20, and the surplus length absorption portion 64 is arranged from the insertion port portion 62 side in the vertical direction of the door 20. It is formed in a shape that gradually moves from the insertion port 62 side toward the outlet port 68 side in the vehicle interior / exterior direction of the door 20 toward the outlet port 68 side. For this reason, the wire harness 42 is absorbed in the surplus length while being deformed also in the twisting direction by entering the surplus length absorbing portion 64 accompanying the closing operation of the door 20. Thereby, the extra length can be absorbed more smoothly by the wire harness 42.

  Further, the twist direction of the plurality of bundled electric wires 43 is set around the direction from the insertion port 62 side to the outlet port 68 side in the vehicle interior / exterior direction of the door 20 when viewed from the extending direction of the wire harness 42. ing. For this reason, the wire harness 42 is absorbed into the extra length while being twisted and deformed in a direction in which the twist of the bundled electric wires 43 is loosened by entering the extra length absorbing portion 64 accompanying the closing operation of the door 20. Thereby, the surplus length can be absorbed more smoothly by reducing the load related to the bending deformation of the wire harness 42.

  In the wire harness 42, a plurality of bundled electric wires 43 are held in a flat shape by the outlet portion 68. For this reason, the portion close to the outlet portion 68 of the wire harness 42 in the surplus length absorbing portion 64 is more reliably maintained in a flat shape, and the load applied to the bending deformation can be reduced in a portion near this portion. It can absorb excess length.

  Further, the wire harness 42 includes a protective portion 44 that covers an outer peripheral portion of a portion spanned between the vehicle body 10 and the door 20 and includes a portion including the end portion on the door 20 side inserted into the insertion port portion 62. The wire harness 42 is held in a flat shape at a portion where a plurality of bundled electric wires 43 extend from the end of the protective portion 44 on the door 20 side. For this reason, the portion of the wire harness 42 extending from the protective portion 44 that is close to the end portion on the door 20 side of the protective portion 44 is more reliably maintained in a flat shape, and the load applied to the bending deformation in the portion near this portion is maintained. Can be reduced. Thereby, the extra length can be absorbed more smoothly by the wire harness 42.

  Further, the surplus length absorbing portion 64 enters the wire harness 42 entering the rear side portion of the door 20 with respect to the insertion port portion 62 with the closing operation of the door 20 on the one side in the vertical direction of the door 20 and on the front side of the door 20. Includes a rear wall portion (third wall portion 643) that can be bent. For this reason, the U-turn can be used to absorb the extra length of the wire harness 42 in a narrower space.

  Further, since the outlet portion 68 is opened downward in the vertical direction of the door 20, the portion of the wire harness 42 bent in a U-turn form in the surplus length absorbing portion 64 accompanying the opening / closing operation of the door 20 is one. The wiring distance of the wire harness 42 to the rear side of the protector 60 in the door 20 can be shortened as much as possible.

  The wire harness 42 is a portion where a plurality of bundled electric wires 43 extend from the end of the protective portion 44 on the door 20 side, and is held in a flat shape along the vertical direction of the door 20, and the outlet portion 68. Thus, the door 20 is held in a flat shape along the outside of the vehicle interior. Thereby, the wire harness 42 is maintained in a more flat shape in a portion extending between the end portion on the door 20 side of the protection portion 44 and the outlet portion 68, and the flat shape portion Twisted. For this reason, the load concerning the wire harness 42 bent and deformed with the opening / closing operation | movement of the door 20 can be reduced more.

  In addition, the wall portion of the protector 60 that extends from the insertion port portion 62 to the extra length absorbing portion 64 in the front-rear direction of the door 20 at the upper end in the vertical direction of the door 20 A retracting portion 644 that swells upward in the vertical direction is included in a portion on the rear side from the position of the end portion on the door 20 side of the protection portion 44 in the open state of 20. For this reason, even if the protection part 44 is pushed upward and downward due to the rigidity of the wire harness 42 that is advanced and retracted into the protector 60 in accordance with the opening / closing operation of the door 20, the protection part 44 is swelled upward. However, the sliding force on the inner surface of the protector 60 can be suppressed. Thereby, while the advance / retreat operation | movement of the wire harness 42 with respect to the protector 60 accompanying the opening / closing operation | movement of the door 20 can be suppressed, abnormal noise can be suppressed.

  Up to now, the twist amount of the wire harness 42 has been described as being approximately 90 degrees, but the present invention is not limited to this. That is, the amount of twist of the wire harness 42 is such that when the bundled electric wires 43 are bent, the extension or compression force applied due to the difference in the extension dimension between the inner and outer circumferences can be suppressed, and the bundled electric wires 43. It should be set to such an extent that can be freely deformed.

  In addition, the protector 60 has been described so far that the outlet portion 68 faces downward. However, when the outlet portion 68 is arranged so as to face upward, the protector 60 is reversed in the vehicle interior / exterior direction. A protector formed in a shape may be employed. That is, in the protector, the wall portion extending from the insertion opening 62 to the surplus length absorbing portion 64 in the front-rear direction of the door 20 at the lower end of the door 20 opens the door 20 in the front-rear direction of the door 20. A retracting portion 644 that swells downward is included in a portion on the rear side from the position of the end portion on the door 20 side of the protection portion 44 in the state. Further, the surplus length absorbing portion 64 bends the wire harness 42 that enters the rear portion of the door 20 with respect to the insertion port portion 62 with the closing operation of the door 20 to the front side of the door 20 above the door 20. Includes a controllable rear wall. Further, the surplus length absorbing portion 64 is formed in a shape that gradually transitions from the outside of the passenger compartment toward the inside of the passenger compartment in the outside of the passenger compartment of the door 20 as it goes from the lower side to the upper side in the vertical direction of the door. Including site.

  Further, the protector 60 disposed on the right side door of the vehicle has been described. However, when the protector 60 is disposed on the left side door, the protector 60 is formed in an inverted shape in the vehicle interior / exterior direction as described above. A protector should be used.

  Further, the example in which the wire harness 42 is routed through the lower portion of the speaker 90 has been described so far. However, when it is difficult to secure a wiring space for the wire harness 42 below the speaker 90, the speaker 90 is disposed. You may route the wire harness 42 above. In this case, the protector 60 is disposed at a position above the speaker 90. The vehicle body hole 11 and the introduction opening 21 are also formed at positions above the speaker 90, respectively.

  Moreover, although the wire harness wiring structure part 30 was demonstrated in the example applied to the door 20 as a front side door, you may apply to the rear side door etc. which are connected with the vehicle body 10 and the hinge part 15. FIG. In this case, the wire harness 42 is bridged between the center pillar (the pillar between the front side door and the rear side door) and the rear side door. That is, the vehicle body hole 11 is formed in the center pillar, and the vehicle body fixing portion 50 is fixed thereto. And the introduction opening part 21 is formed in the front side edge part of a rear side door, and the protector 60 is arrange | positioned in a rear side door.

Second Embodiment
Hereinafter, the wire harness wiring structure part 130 which concerns on 2nd Embodiment is demonstrated (refer FIG. 12). Of the wire harness routing structure portion 130, the configuration different from the wire harness routing structure portion 30 according to the first embodiment is only the routing configuration of the protector 160 and the wire harness 42 inside thereof, and the same configuration. The description will be omitted and will be given the same reference numerals.

  The protector 160 includes an insertion port portion 62 and a surplus length absorbing portion 164 (see FIGS. 13 to 16).

  The surplus length absorbing portion 164 is a portion that accommodates the wire harness 42 that extends from the end portion on the door 20 side of the protective portion 44 with a margin space that can be bypassed (see FIG. 17). The extra length absorbing portion 164 is formed continuously behind the insertion port portion 62.
