This wire harness routing structure 10 routes the wire harness WH from the vehicle body 2 to the door 6. Here, the vehicle body 2 includes an interior member such as an instrument panel 3 formed of a resin in addition to a frame portion formed of a metal member.

  The wire harness WH is configured by appropriately bundling a plurality of electric wires for supplying power or transmitting signals to electric devices such as a power window and a door lock mounted on the door 6 corresponding to the routing route. (See FIGS. 2 and 5). Here, what is routed from the vehicle body 2 to the door 6 in the wire harness WH is a portion where a plurality of electric wires are bundled together. And the wire harness WH branches in the door 6 and is connected to various electric equipment.

  The door 6 is connected to the vehicle body 2 by a door hinge 5 so that the doorway of the vehicle body 2 can be opened and closed (see FIGS. 1 and 4). For convenience of explanation, it is assumed that the door 6 is connected to the vehicle body 2 so as to change its posture around an axis along the vertical direction.

  Waterproof weather strips 2w and 6w are attached to the vehicle body 2 and the door 6 along the peripheral edge of the door 6 or the opening edge of the entrance / exit of the vehicle body 2 (opening edge of the frame 4), respectively. (See FIGS. 1, 2, 4, and 5). The weather strips 2w and 6w are formed of rubber or the like that can be kept in a watertight state in the vehicle interior and exterior in close contact with the opening edge of the frame 4 of the vehicle body 2 or the peripheral edge of the door 6 with the door 6 closed. It is a member.

  The wire harness WH is routed between the vehicle body 2 and the door 6 from the weather strips 2w and 6w to the vehicle interior side (see FIGS. 1 and 4). In this example, the wire harness WH is bridged from the side of the instrument panel 3 of the vehicle body 2 to the front side end of the vehicle body 2 of the front side door and routed between the vehicle body 2 and the door 6. explain. In addition, the instrument panel 3 does not indicate only a portion that covers the instruments, but includes an interior member (also referred to as a dashboard) in the vicinity thereof (in front of the front row seat).

  A vehicle body side hole 3 h for inserting the wire harness WH into the instrument panel 3 is formed on the side of the instrument panel 3 of the vehicle body 2. The vehicle body side hole 3h is formed on the vehicle interior side with respect to the weather strips 2w and 6w. The door 6 has a door inner panel 7 made of a metal material and a trim 8 as an interior member made of a resin material or the like. A door-side recess for inserting the wire harness WH into the door 6 is formed in one or both of the door inner panel 7 and the trim 8 at a portion of the door 6 on the front end side of the vehicle body 2. Here, door side recesses 7h, 8h are formed in both the door inner panel 7 and the trim 8. The wire harness WH is bridged from the vehicle body 2 side through the vehicle body side hole 3h to the door 6 side, and routed between the door inner panel 7 and the trim 8 through the door side recesses 7h and 8h (FIG. 3, 6 and FIG. 10), and is branched and connected to various electric devices (see FIG. 2 and FIG. 5). The portion of the vehicle body 2 in which the vehicle body side hole 3h is formed and the portion of the door 6 in which the door side recesses 7h and 8h are formed face the vehicle body 2 or the door 6 with the door 6 closed. It is difficult to see from the passenger compartment.

  The wire harness routing structure unit 10 includes an exterior member 20, an attachment member 30, a housing unit 40, a guide unit 50, and a flexible soundproof member 60 (see FIGS. 1 and 4).

  A portion of the wire harness WH that extends from the vehicle body 2 to the door 6 is covered with an exterior member 20. The exterior member 20 is a member that protects the wire harness WH from the outside in a state where the wire harness WH is inserted, and supports the wire harness WH while suppressing dripping between the vehicle body 2 and the door 6.

  The exterior member 20 is formed in a cylindrical shape, and protects in a state where the wire harness WH is inserted. More specifically, the exterior member 20 is a member having flexibility so as to bend between the vehicle body 2 and the door 6 corresponding to the opening / closing operation of the door 6. Here, the exterior member 20 is a corrugated tube manufactured by extrusion molding and vacuum molding or blow molding of an elastomer such as synthetic resin or synthetic rubber. The exterior member 20 is formed in a flat shape (for example, a flat shape such as a substantially elliptical shape or a substantially rectangular shape in cross section). In addition, the wire harness WH itself is also bundled in a flat shape, and the exterior member 20 is good to be formed in the flat shape corresponding to the external shape of the wire harness WH.

  But the exterior member 20 is not restricted to the said corrugated tube. For example, as the exterior member, a protector manufactured in a rectangular tube shape or a cylindrical shape by injection molding resin with a mold may be used. In this case, it is preferable that one end of the exterior member is attached to the vehicle body side via a hinge so that the exterior member can be operated corresponding to the opening / closing operation of the door 6.

  One end side portion of the exterior member 20 is fixed to the vehicle body 2 via the attachment member 30, and the other end portion is a free end.

  The attachment member 30 is a member that attaches one end of the exterior member 20 that is sheathed to the wire harness WH to the vehicle body 2 so as to route the wire harness WH to the vehicle body 2 side. The attachment member 30 is configured such that one end side portion of the exterior member 20 is fixed and can be attached to the vehicle body 2. Here, the attachment member 30 is attached to the vehicle body side hole 3h for insertion of the wire harness WH formed on the side of the instrument panel 3. More specifically, the attachment member 30 is configured to be attachable by pressing from one side (here, the door side) against the vehicle body side hole 3h. The mounting member 30 includes a fitting portion 32 that can be fitted into the vehicle body side hole 3h, and a positioning portion 38 that can position one end side portion of the exterior member 20 (FIGS. 7 and 8). reference).

  The fitting part 32 has an insertion part 34 and a pressing part 36. The insertion portion 34 is formed in a cylindrical shape that can be inserted into the vehicle body side hole portion 3h and that allows the exterior member 20 to be inserted inside. The insertion portion 34 is inserted from the door side into the vehicle body side hole portion 3h (hereinafter, this direction is referred to as an insertion direction S). A locking portion 35 that can be locked to the vehicle body side hole 3h in a state where the insertion portion 34 is inserted into the vehicle body side hole 3h is provided at the distal end portion of the insertion portion 34. The locking portions 35 are formed so as to protrude outward from a plurality of circumferential positions of the insertion portion 34 (here, four locations at equal intervals), and are each inserted in the insertion direction with respect to the peripheral portion of the vehicle body side hole 3h. S has a locking surface that can be contacted from the front side. More specifically, the locking portion 35 is formed so that the protruding dimension gradually increases from the distal end side to the proximal end side of the insertion portion 34. When each of the locking portions 35 is inserted into the vehicle body side hole 3h, the insertion portion 34 or the locking portion 35 itself is elastically deformed toward the inner peripheral side of the insertion portion 34, so that the vehicle side hole At the position over the portion 3h, the elastic return to the outer peripheral side is achieved and the peripheral portion of the vehicle body side hole 3h is locked.

  The presser portion 36 is provided continuously with the proximal end portion of the insertion portion 34, and is formed in a hook shape that protrudes to the outer peripheral side thereof. The presser portion 36 can come into surface contact with the peripheral portion of the vehicle body side hole 3h from the rear side in the insertion direction S. That is, the outer peripheral shape of the presser portion 36 is formed larger than the vehicle body side hole portion 3h.

  When the insertion portion 34 is inserted into the vehicle body side hole 3h, the presser portion 36 is in the state where the locking portion 35 is locked from the front side in the insertion direction S with respect to the peripheral portion of the vehicle body side hole 3h. Surface contact is made from the rear side in the insertion direction S to the peripheral edge of the side hole 3h. As a result, the peripheral edge portion of the vehicle body side hole 3h is sandwiched between the locking portion 35 and the pressing portion 36, and the fitting portion 32 is engaged with the vehicle body side hole 3h.

  The positioning portion 38 is formed so as to protrude in a plate shape toward the rear in the insertion direction S from the inner peripheral portion of the base end portion of the fitting portion 32 (base end portion of the pressing portion 36). Then, in a state where the wire harness WH is inserted into the fitting portion 32, the wire harness WH is fastened to the positioning portion 38 with a tape T or a tie band to fix the wire harness WH to the attachment member 30. Fixed against. The tie band refers to a member that can change and retain the circumferential dimension of the annular body by selectively locking the locking portion to a plurality of locked portions. In FIG. 8, the form wound with the tape T is shown. Further, a protrusion for preventing the tape T or the tie band from being removed may be formed at the tip of the positioning portion 38. That is, a portion that protrudes from the distal end portion of the positioning portion 38 toward the outer peripheral side of the fitting portion 32 may be provided.

  The positioning portion 38 is not limited to a shape protruding toward the rear in the insertion direction S of the fitting portion 32, and is inserted along the route corresponding to the route of the exterior member 20 inserted through the fitting portion 32. You may protrude in the direction inclined with respect to the direction S.

  The mounting member 30 may be integrally formed by injection molding a resin material.

  But the attachment member 30 is not restricted to the said form. For example, the attachment member 30 may be configured to be fitted to the outer peripheral portion of the corrugated tube as the exterior member 20 and to be attachable to the vehicle body side hole 3h in this fitted state. More specifically, a pair of blocks having a shape in which the fitting portion 32 of the mounting member 30 is halved are connected to each other by hinges so that the ends can be opened and closed. A configuration in which concave and convex surfaces corresponding to the outer peripheral shape of the corrugated tube are continuously formed in the insertion direction S at each inner peripheral portion so as to be fitted to each other can be adopted. That is, the corrugated tube can be fitted and positioned by sandwiching the corrugated tube between the pair of blocks, and in this state, the corrugated tube is fitted and attached to the vehicle body side hole 3h. According to this configuration of the mounting member, the mounting position is adjusted in the subsequent assembly process even if the wire harness WH and the exterior member 20 are not inserted before the vehicle assembly of the wire harness routing structure 10. Can be attached while. Thus, from the viewpoint of adjusting the mounting position in the vehicle assembly process, it is preferable to employ a fitting structure using a hinge as the mounting member.

  Further, the attachment member 30 only needs to be attachable to the vehicle body 2 and fix the exterior member 20, and is not limited to the resin molded product as described above, and may be a grommet formed of an elastomer such as synthetic rubber. Good.

  The accommodating portion 40 is configured to be able to accommodate the extra length so that the wire harness WH extending from the other end portion of the exterior member 20 can be detoured (wrapped here) so as to absorb the extra length (see FIGS. 2 and 5). Moreover, the guide part 50 is formed in the groove shape or the cylinder shape extended so that the other end side part made into the free end among the exterior members 20 toward the accommodating part 40 can be inserted and guided. Here, the accommodating part 40 and the guide part 50 are shape | molded as the protector P of one part.

  More specifically, the guide part 50 has an entrance through which the other end side portion of the wire harness WH can be inserted at one end, and the other end is continuous with one end of the accommodating part 40. The housing portion 40 has a housing space in which one end portion is continuous with the guide portion 50 and can be housed by winding a wire harness WH extending from the other end portion of the exterior member 20 inserted into the guide portion 50. It is formed in a shape. That is, the accommodating space of the accommodating portion 40 communicates with the other end side of the internal space of the guide portion 50 extending toward the accommodating portion 40. Further, the accommodating portion 40 is formed with an outlet 42 through which the wound wire harness WH can be drawn into the door 6. That is, the protector P guides the exterior member 20 inserted into the guide portion 50 toward the housing portion 40, and winds the wire harness WH extending from the other end portion of the exterior member 20 in the housing portion 40. Accommodates and extends outward through the outlet 42.

  In the protector P, in the closed state of the door 6, the guide portion 50 extends along the front-rear direction of the vehicle body 2 through the door-side recess 7 h, and the guide portion 50 is on the front side of the vehicle body 2 with respect to the housing portion 40. It is arrange | positioned between the door inner panel 7 and the trim 8 so that it may be located. More specifically, the position of one end portion of the guide portion 50 is behind the vehicle body side hole portion 3h in the front-rear direction of the vehicle body 2 with the door 6 closed.

  Further, the protector P is configured to be fixed to the door inner panel 7 at the above position. As this configuration, a configuration having a clamp structure that can be fitted to a hole formed in the door inner panel 7 or a configuration having a bracket structure that can be fixed by screwing can be employed. The protector P can be applied to both the left and right doors 6 of the automobile by providing a structure that can be fixed to the door inner panel 7 on both sides thereof, and is excellent in versatility and contributes to cost reduction.

  Hereinafter, the structure of each of the guide part 50 and the accommodating part 40 will be described in more detail.

  The guide part 50 is formed in a cylindrical shape (here, a rectangular cylindrical shape in a cross-sectional view) having an internal space larger than the exterior member 20. But the guide part 50 should just be able to insert and guide the exterior member 20, and may be formed in the shape of a groove or a cylinder such as a substantially elliptical shape in cross section, a circle, or a polygon other than a rectangle.

  This guide part 50 is formed so that one end side part may spread as it goes to one edge part. That is, when the door 6 is opened and closed, the exterior member 20 is interlocked with the door 6 while being bent about a substantially vertical axis of the vehicle body 2 between the vehicle body 2 and the door 6. And the exterior member bent about the axis | shaft of a substantially up-down direction by employ | adopting the shape (refer FIG. 1, FIG. 4) which the one end part of the guide part 50 spread in the width direction (here inside and outside direction of the door 6). 20 can be smoothly guided into the guide unit 50.

  Further, the attachment member 30 and one end portion of the guide portion 50 are provided at positions shifted in the substantially vertical direction of the vehicle body 2. That is, the exterior member 20 has a height difference between the one end side portion fixed to the mounting member 30 and the other end side portion inserted into the guide portion 50, and a step in the substantially vertical direction of the vehicle body 2 at a position between them. (See FIGS. 2 and 5). For example, the exterior member 20 may be bridged with a step of 30 mm or more. This configuration is for dispersing the force applied to the wire harness WH spanned between the vehicle body 2 and the door 6.

  That is, when the exterior member 20 extends on the horizontal plane and is bent on the horizontal plane according to the opening / closing operation of the door 6, it is assumed that a part of the exterior member 20 is bent with a bend. In this case, the wire harness WH inside the exterior member is also bent at a part, and there is a fear that a force is applied concentrated on the part. On the other hand, when the exterior member 20 is configured to extend with a step in the height direction, as shown in FIG. 9, when the door 6 is opened and closed, the exterior member 20 is around the axis of the vehicle body 2 in the substantially vertical direction. When bent to the center, the inner wire harness WH twists around the central axis at a portion extending in the substantially vertical direction of the vehicle body 2. For this reason, the force applied to the wire harness WH inside the exterior member 20 when the door 6 is opened and closed is distributed in the bending direction around the substantially vertical axis of the vehicle body 2 and the twisting direction around the central axis. Further, the force applied in the twisting direction acts in a wider range in the extending direction of the wire harness WH than the force applied in the bending direction. For this reason, in the wire harness WH, the location where force acts is also dispersed. Thereby, the deformation amount of the wire harness WH in the bending direction is reduced, and the load applied to a part can be reduced. In FIG. 9, the exterior member 20 in the closed state of the door 6 is shown by a solid line, and the exterior member 20 in the opened state of the door 6 is shown by a two-dot chain line, and the wire harness WH when the door 6 is opened from the closed state is shown. The twist direction is indicated by an arrow W.

  Here, the attachment member 30 is provided at a position higher than one end portion of the guide portion 50. In other words, the vehicle body side hole 3h is provided at a position higher than the door side recesses 7h, 8h. But the attachment member 30 and the one end part of the guide part 50 may be provided in the same height position, but when it says from a viewpoint which disperse | distributes the force added to the said wire harness WH, it is the attachment member 30 and the guide part 50. The height position with respect to one end may be shifted.

  As described above, corresponding to the configuration in which the attachment member 30 and one end portion of the guide portion 50 are shifted in the substantially vertical direction of the vehicle body 2, the one end side portion of the guide portion 50 is substantially vertical in the vehicle body 2. It is formed so as to spread at least toward the mounting member 30 in the direction. That is, since the exterior member 20 extends in an inclined direction from the guide portion 50 side (here, the lower side) toward the attachment member 30 side (here, the upper side) in the substantially vertical direction of the vehicle body 2, It is preferable to spread in (upper side).

  Here, the guide part 50 is formed in a trumpet shape in which the entire circumferential direction of the one end side portion extends toward the one end edge (see FIGS. 1, 2, 4, and 5). As a result, the protector P can be applied to both the left and right doors, and can also be applied to a case where one end portion of the guide portion 50 is provided at a higher position than the mounting member 30. Also contribute. Moreover, the one end side part of the guide part 50 has spread so that a smooth curve may be drawn.

  Here, the relationship between the guide part 50 and the exterior member 20 is demonstrated. The exterior member 20 is inserted into the guide portion 50 at least when the door 6 is in an open state with one end side portion fixed to an attachment member 30 attached to the vehicle body 2. It is preferable that the extension dimension is set to be as long as possible. On the other hand, when the door 6 is in the closed state, the guide portion 50 may be set to have a long extension dimension that can accommodate the other end portion of the exterior member 20 entering inward to the other end portion. As described above, the other end portion of the exterior member 20 moves while being guided in the extending direction in the guide portion 50 when the door 6 is opened and closed. The forward / backward movement amount of the other end portion of the exterior member 20 with respect to the guide portion 50 varies depending on the opening / closing mode of the door 6, but when the door member 6 is moved, for example, 100 mm, the extension dimension of the guide portion 50 is set to be larger than 100 mm. However, the guide portion 50 may be shorter than the above dimensions, and the other end of the exterior member 20 may protrude into the accommodating portion 40 beyond the other end of the guide portion 50 when the door 6 is closed. The wire harness WH extending from the other end of the wire 20 is preferably set so as not to prevent the wire harness WH from being wound in the housing portion 40.

  The accommodating part 40 is formed so that it can be accommodated by winding the wire harness WH that enters the accommodating space when the door 6 is closed. Here, the wire harness WH can be housed by winding it once. Preferably, the accommodating part 40 is large enough to wind the wire harness WH without bending it in the accommodating space. Further, the inner width dimension (inner / outer dimension of the door 6) of the accommodating portion 40 can intersect the wound wire harness WH, that is, larger than twice the diameter of the wire harness WH (here, slightly larger). Is set. In FIGS. 1 and 4, the accommodating portion 40 and the guide portion 50 are represented by substantially the same width dimension (inside and outside direction dimensions of the door 6), but the guide portion 50 corresponds to the outer shape of the exterior member 20. The cross-sectional shape may be formed and may be set to a width dimension smaller than the accommodating portion 40.

  A winding shaft portion 44 is provided in the housing portion 40. The winding shaft portion 44 is formed in a columnar shape (here, a columnar shape) extending in the width direction of the housing portion 40. The wire harness WH accommodated in the accommodating portion 40 is wound around the winding shaft portion 44. More specifically, the winding shaft part 44 should just be provided in the outer peripheral side with the space | interval which can arrange | position the wire harness WH with respect to the inner peripheral part of the accommodating part 40. FIG.

  Further, the outlet 42 of the housing part 40 opens at a position facing the communication part with the guide part 50 in the housing part 40. The outlet 42 is formed with an in-door positioning part 43 having a shape in which the opening edge partly extends.

  Then, the wire harness WH pulled out from the outlet 42 is fastened and fixed to the in-door positioning portion 43 with a tape T winding or a tie band, so that the wire harness WH is placed inside the door 6 outside the housing portion 40. 6 is positioned. For this reason, even if the wire harness WH on the vehicle body 2 side advances and retreats in the housing portion 40 when the door 6 is opened and closed, it is possible to suppress the occurrence of pulling or slacking with respect to the wire harness WH routed in the door 6. . In FIGS. 2 and 5, the tape T is wound.

  In addition, as a configuration for fixing the wire harness WH to the housing portion 40, with respect to the annular member provided with a plurality of claw portions protruding radially inward so as to be elastically deformable in the radial direction, It is possible to adopt a configuration that allows the plurality of claw portions to be elastically deformed radially inward by fitting the outer fitting member. The annular member may be fixed to the outlet 42. That is, the wire harness WH can be fixed to the accommodating portion 40 by fitting the outer fitting member to the annular member while the wire harness WH is inserted through the annular member.

  For example, the protector P having the housing portion 40 and the guide portion 50 may employ a configuration in which a concave member and a lid-like member are combined. 2, 3, 5, and 6 show the protector P from which the lid-like member is omitted. Then, the protector P can be obtained by combining the concave member and the lid-like member by pouring a resin material into a mold, injection molding, and combining them. However, the protector P may be formed in a concave shape as a whole and configured so that the opening is closed by the trim 8.

  However, the accommodating portion 40 and the guide portion 50 are not limited to being formed as a one-piece protector P, and a separate accommodating portion 40 is provided on the other end side of the guide portion 50 to guide the It is only necessary that the exterior member 20 is guided by the portion 50 toward the housing portion 40.

  Moreover, the protector P is not restricted to the said structure, A structure like the protector Pa shown in FIG. 11 can also be employ | adopted. The protector Pa has a guide portion 50 and a housing portion 40a, and the wire harness WH is inserted from the entrance / exit of the guide portion 50, and the extra length is absorbed in the housing portion 40a, and is opened in a direction substantially orthogonal to the entrance / exit. It can be pulled out into the door 6 through the outlet 42a. The accommodating portion 40a has one wall surface formed in a gentle curved surface from the guide portion 50 toward the outlet 42a, and the other wall surface swelled in a direction away from the guide portion 50 and then toward the outlet 42a. doing. And the accommodating part 40 can accommodate the accommodated wire harness WH between the path | route (solid line of FIG. 11) along one wall surface, and the path | route (two-dot chain line of FIG. 11) along the other wall surface. It is. That is, the wire harness WH accommodated in the accommodating portion 40a is accommodated in a shape approaching the path along one wall surface when the surplus length is relatively small, and the path along the other wall surface as the surplus length increases. It is housed in a shape that approaches. Also in this configuration, the wire harness WH can be fixed to the accommodating portion 50 by being taped to the door side positioning portion 43a and fastened by a tie band. Further, the wire harness WH can be fixed to the housing portion 50 also by a combination of the annular member having the plurality of claw portions and the external fitting member.

  The flexible soundproof member 60 is a member for suppressing the generation of noise due to the exterior member 20 inserted between the door inner panel 7 and the trim 8 being rubbed against the door inner panel 7 or the trim 8. That is, the exterior member 20 is inserted into the door 6 (inside the guide portion 50) through the door-side recesses 7h and 8h when the door 6 is opened and closed. There is a risk of coming into contact with the side recesses 7h, 8h. And since these door side recessed parts 7h and 8h are a part of the door inner panel 7 formed with a metal material or the trim 8 formed with a resin material, they are comparatively hard and will contact and rub against the exterior member 20. An abnormal noise occurs.

  The flexible soundproof member 60 is provided on one end side of the guide portion 50, and the exterior member 20 is inserted through the outer periphery of the exterior member 20. That is, the other end portion of the exterior member 20 is inserted into the door 6 through the flexible soundproof member 60.

  The flexible soundproof member 60 is formed of a material (here, an elastomer such as synthetic rubber) that is softer than the door inner panel 7 and the trim 8. That is, the flexible soundproofing member 60 is formed of a material such that the sound when the exterior member 20 contacts and rubs is smaller than the sound when the door inner panel 7 and the trim 8 contact and rub. For this reason, in terms of soundproof performance, the flexible soundproof member 60 is preferably formed of a more flexible material.

  Here, the flexible soundproof member 60 has a slit through which the exterior member 20 can be inserted, and is provided so as to close the door-side recess 8 h of the trim 8. The flexible soundproof member 60 is provided in a posture in which the slit extends in the front-rear direction of the vehicle body 2 with the door 6 closed. More specifically, in the flexible soundproofing member 60, the pair of facing pieces facing each other across the slit is easily elastically deformed, and the inserted exterior member 20 can easily push and retract the pair of facing pieces to advance and retreat. . For example, the pair of opposed pieces may be formed so as to be thin and have a thickness dimension that decreases toward the leading end side facing the pair. In addition, the flexible soundproof member 60 may have a wide slit so as not to prevent the exterior member 20 from moving back and forth in the guide portion 50 (not caught by the exterior member 20). On the other hand, the exterior member 20 is preferably hard (not easily bent) to such an extent that the flexible soundproof member 60 can be pushed away and moved back and forth in the guide portion 50. As described above, since the flexible soundproof member 60 is provided so as to close the door side recess 8h of the trim 8, the door side recess 8h is blocked and the inside of the door 6 is difficult to see, and the appearance of the door 6 in the open state is visible. Will also improve.

  The exterior member 20 is inserted into the guide portion 50 in the door 6 through the slit of the flexible soundproof member 60, and moves in the extension direction in the door 6 (guide portion 50) while moving in the slit when the door 6 is opened and closed. Will be moved forward and backward.

  However, the flexible soundproof member 60 is not limited to the shape in which the slit is formed. For example, in the flexible soundproof member, a plurality of substantially triangular portions in which the tip portion located at the one point is a free end are arranged in the circumferential direction by being cut radially with respect to the thin rubber. Shape can be adopted. Then, the flexible soundproofing member may be provided on the trim 8 so as to close the door-side recess 8h, and may be provided so as to insert the exterior member 20 by spreading the distal ends of a plurality of substantially triangular portions. In addition, the flexible soundproofing member may be formed in a brush shape with hair, flexible resin, rubber, or the like, and may be provided so that the exterior member 20 is inserted between the tip portions.

  The flexible soundproof member 60 may be provided on the protector P. For example, the protector is provided with an extension portion for attaching a flexible soundproofing member extending to one end side of the guide portion 50, the flexible soundproofing member is provided at the extension portion, and the wire harness WH is inserted into the guide portion 50 through the flexible soundproofing member. You may comprise so that it may insert. In this case, the flexible soundproofing member is preferably provided at substantially the same position as that when the trim 8 is attached to the door-side recess 8h. Specifically, the door-side recess 8h is disposed inside the trim 8 (the door inner panel 7). It is good to be provided so as to close from the side.

  The wire harness routing structure 10 can modularize the wire harness WH, the exterior member 20, the mounting member 30, and the protector P that are routed from the vehicle body 2 into the door 6, and can be assembled before the vehicle is assembled. . That is, the wire harness WH is disposed in the exterior member 20 and is disposed in the guide portion 50 and the accommodating portion 40 of the protector P and fixed to the in-door positioning portion 43, and one end side portion of the exterior member 20 is attached to the mounting member. It may be inserted into 30 and fixed. The flexible soundproof member 60 can also be assembled in a state where the exterior member 20 is inserted before the vehicle is assembled. Moreover, when a flexible soundproof member is provided in a protector, the whole wire harness routing structure part can be modularized more easily.

  The wire harness routing structure portion 10 is not limited to the case where the attachment member 30 is attached to the vehicle body side hole portion 3h formed in the side portion of the instrument panel 3. For example, as shown in FIG. 12, a vehicle body side hole 4h may be formed in a part of the frame 4a of the vehicle body 2a, and the attachment member 30 may be attached to the vehicle body side hole 4h. That is, in this case, the wire harness WH is bridged between the frame 4 a of the vehicle body 2 and the door 6.

  Moreover, although the wire harness arrangement | positioning structure part 10 was demonstrated by the example applied between the vehicle body 2 and the front side door as the door 6 until now, it is applicable also to a rear side door. In this case, the wire harness WH 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, a vehicle body side hole is formed in the center pillar, and an attachment member is attached here.

  According to the wire harness arrangement structure unit 10 according to the above configuration, the exterior member 20 that is externally mounted on the wire harness WH is guided by the guide unit 50 toward the housing unit 40 that absorbs the extra length of the wire harness WH. Yes. Furthermore, the guide part 50 is formed so that the one end side part on the opposite side to the accommodating part 40 may spread as it goes to one end edge part. For this reason, by guiding the exterior member 20 to the guide portion 50, the wire harness WH routed between the vehicle body 2 and the door 6 can be more smoothly interlocked with the opening / closing operation of the door 6.

  Further, the attachment member 30 and one end of the guide portion 50 are provided at positions shifted in the substantially vertical direction of the vehicle body 2. That is, the wire harness WH in the exterior member 20 extending between the mounting member 30 and one end of the guide portion 50 is on a plane where both end portions are different in the substantially vertical direction of the vehicle body 2 when the door 6 is opened and closed. Therefore, the portion extending and displaced in the substantially vertical direction of the vehicle body 2 in the meantime is deformed not only in the bending deformation but also in the twisting direction. Thereby, the force applied to the wire harness WH can be dispersed, and local load can be suppressed. And since the one end side part of the guide part 50 is formed so that it may spread at least to the attachment member 30 side among the substantially up-down directions of the vehicle body 2, the wire harness in the exterior member 20 extended and displaced also in a substantially up-down direction. WH can be more smoothly interlocked with the opening / closing operation of the door 6.

  Further, the flexible soundproofing member 60 is provided on one end side of the guide portion 50 and is inserted through the exterior member 20 so as to contact the outer peripheral portion of the exterior member 20, so that the flexible soundproof member 60 advances and retracts into the guide portion 50 when the door 6 is opened and closed. The exterior member 20 to be rubbed against the door inner panel 7 and the trim 8 (particularly, the door-side recesses 7h and 8h) can be prevented from generating abnormal noise.

  In addition, the attachment member 30 is positioned by positioning the one end side portion of the exterior member 20 that is externally mounted on the wire harness WH by the positioning portion 38, and the fitting portion 32 is fitted by simply pressing the vehicle body side hole portion 3h from one side. Since it is comprised so that it may match, wiring harness WH can be easily routed to the vehicle body 2 side.

  Further, since the exterior member 20 is formed in a flat shape and is provided in a flat posture along the vertical direction of the vehicle body 2, it can be arranged in a narrow space in the inside and outside of the door 6 and is disposed in the door 6. The guide part 50 and the accommodating part 40 to be made can also be made flat, and can be applied even in the case of the door 6 in which the space between the door inner panel 7 and the trim 8 is narrow.

  Moreover, since the wire harness wiring structure part 10 has wired the wire harness WH to the vehicle interior side from the weather strips 2w and 6w, the member for water-stopping, such as a grommet, is abbreviate | omitted, and a number of parts and assembly man-hours Reduction, cost reduction associated with this, and work efficiency can be improved. In addition, according to the structure which does not use a grommet, preparing the cover for preventing a grommet deformation | transformation at the time of transportation and packing can be abbreviate | omitted. It also contributes to theft prevention. Moreover, the expansion work of the grommet at the time of letting the wire harness WH pass can also be abbreviate | omitted compared with the case where it attaches to the door 6 side with a grommet.

  In addition, since the wire harness routing structure unit 10 routes the wire harness WH between the door inner panel 7 and the trim 8, it can save the trouble of routing the wire harness WH through the through hole. Assembling work can be performed in the exposed work space, so that assembling performance can be improved and work efficiency can be improved.
