  Hereinafter, the wire harness wiring structure part 10 which concerns on embodiment is demonstrated (refer FIG. 1). The wire harness routing structure 10 is configured to route the wire harness WH between the vehicle body 2 and the door 6 of the automobile.

  In the wiring harness WH, a plurality of electric wires for supplying power or transmitting signals to electrical devices such as a switch, a power window motor, a door lock motor, a side mirror motor, and a speaker installed in the door 6 are arranged in the routing route. Correspondingly, they are appropriately bundled. Here, the portion of the wire harness WH that extends from the vehicle body 2 to the door 6 is configured by bundling the plurality of electric wires into one. Further, the wire harness WH is branched in the door 6 and connected to various electric devices (not shown).

  For convenience of explanation, the vehicle body 2 and the door 6 will be described. The door 6 is connected to the vehicle body 2 by a door hinge 5 and an opening degree restricting unit 3 so as to be able to open and close the entrance / exit formed in the vehicle body 2. The vehicle body 2 refers to a frame portion formed of a metal member. Here, the door 6 is a front side door, and 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 (the rotation axis of the door hinge 5). In the closed state of the door 6, an end portion (a connected end portion) located on the front side of the vehicle is referred to as a front end portion, and an end portion located on the rear side is referred to as a rear end portion. In addition, for the door 6, the direction connecting the inside and outside of the vehicle may be referred to as the thickness direction.

  The opening degree restricting unit 3 (also referred to as a door check link) is a configuration for maintaining the door 6 at a predetermined opening degree (full open posture, half open posture, etc.). More specifically, the opening degree restricting part 3 has an arm part and a case part. The arm portion is formed in a rod shape in which one end portion is connected to the vehicle body 2 so as to be relatively rotatable, and a portion thinner than the other portion is formed at a plurality of positions in the longitudinal direction. The case portion is fixed to the door 6 and is formed in a casing shape having a through-hole through which the arm portion can be inserted, and has a holding portion that is pressed and urged so as to sandwich the arm portion. That is, the case part is likely to stay at a position where the sandwiching part sandwiches the thin part with respect to the inserted arm part. Then, the arm part is relatively inserted and moved with respect to the case part in conjunction with the opening / closing operation of the door 6. In a state where the sandwiching portion of the case portion is in a position sandwiching the thin portion of the arm portion, the posture of the door 6 is maintained unless an external force that can get over the thick portion is applied. In general, the position of the thin wall portion of the arm portion is set so that the posture can be maintained in the half-open posture and the fully-open posture of the door 6.

  The door 6 is formed of a door inner panel 7 formed by press molding, punching, or the like of a metal plate, a door outer panel as an exterior member provided outside the door, a synthetic resin material, and the like. It has a trim 8 as an interior member attached to the inside (see FIG. 2). Further, the door 6 is connected to the inside and outside of the wire harness WH through an introduction opening 6h that opens at an edge of the connection side (front end side) with the vehicle body 2 (an edge of the door 6 on the attachment position side of a vehicle attachment member 30 described later). It is configured so that it can be routed. Here, the introduction opening 6 h of the door 6 is formed by an opening edge opening toward the front end side of the door 6 in the recess 7 h formed in the door inner panel 7 and an edge on the front end side of the trim 8. It is an opening (see FIG. 6). The concave portion 7h is a concave portion that partially or entirely accommodates the protector P to be described later, and opens at the vehicle inner side of the door inner panel 7 and opens at the front end side of the door 6 as described above.

  Further, the vehicle body 2 is formed with a through-hole portion 2h for inserting and routing the wire harness WH inside and outside. The through-hole portion 2h is formed at a portion facing the introduction opening portion 6h in the closed state of the door 6 at the opening edge portion of the entrance / exit in plan view (see FIG. 4). The introduction opening 6h and the through hole 2h are shielded and hidden from the interior of the vehicle by the interior member attached to the vehicle body 2, the trim 8 of the door 6 and the like when the door 6 is closed.

  Moreover, the weather strip 6w for waterproofing is provided in the door 6 along the peripheral part (refer FIG. 2, FIG. 4). The weather strip 6w is an elastic member formed of rubber or the like that can be in close contact with the opening edge of the entrance / exit of the vehicle body 2 and keep a watertight state inside and outside the vehicle with the door 6 closed. And this wire harness wiring structure part 10 is comprised so that the wire harness WH may be wired from the weather strip 6w to the vehicle inside.

  Further, here, the wire harness WH is routed between the vehicle body 2 and the door 6 from the weather strip 6w (at least one of the outermost sides of the vehicle when provided in plural), so that the introduction opening 6h And the through-hole part 2h is formed inside the weather strip 6w.

  The wire harness wiring structure 10 includes the wire harness WH, the exterior member 20, the vehicle body attachment member 30, the protector P, and the grommet 60 (see FIG. 1).

  A portion of the wire harness WH including a portion spanned from the vehicle body 2 to the door 6 is covered with the exterior member 20. The exterior member 20 is a member that protects the wire harness WH from the outside and supports the wire harness WH while suppressing bending, drooping, and the like between the vehicle body 2 and the door 6.

  The exterior member 20 is formed in a cylindrical shape and protects the wire harness WH inserted through the hollow portion. More specifically, the exterior member 20 has flexibility (entirely in the extending direction) so as to bend between the vehicle body 2 and the door 6 in response to the opening / closing operation of the door 6. It is a member having rigidity capable of supporting the wire harness WH by suppressing bending and sagging with the door 6, that is, a rigidity higher than at least the wire harness WH. Here, the exterior member 20 is a corrugated tube manufactured by extrusion molding and blow molding or vacuum molding of a synthetic resin (for example, PP (polypropylene), PA (polyamide), etc.). The corrugated tube is a member in which convex ridges and concave valleys along the circumferential direction are alternately continued in the axial direction. And in the cross-sectional view parallel to the axial direction of the corrugated tube, the inner angle between the top of the peak and the side walls on both sides and the inner angle between the bottom of the valley and the side walls on both sides change in size. It expands and contracts. That is, when a force is applied in the bending direction, the corrugated tube is deformed and bent so that each inner angle of the inner peripheral portion becomes smaller and each inner angle of the outer peripheral portion becomes larger. The wire harness WH inserted through the corrugated tube as the exterior member 20 having higher rigidity than the wire harness WH is restricted by the rigidity of the exterior member 20 and the bending is suppressed.

  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). Here, it is formed in a substantially rectangular shape in section view with rounded corners. That is, it is a shape that is difficult to bend in the longitudinal direction (high rigidity) in a cross-sectional view, and is easy to bend in the short direction (high flexibility). More specifically, since the corrugated tube can be expanded and contracted in the axial direction normally at any part in the circumferential direction, the longer the distance between the inner peripheral side end part and the outer peripheral side end part, the smaller the angle change amount and the more difficult it is to bend. Note that the wire harness WH may be formed in a circular shape in cross section, or may be formed in a cross sectional shape corresponding to the internal shape of the exterior member 20.

  But the exterior member 20 should just have rigidity higher than the wire harness WH, and is not limited to the corrugated tube mentioned above. For example, the exterior member may be a flat cylinder formed of a relatively hard rubber (EPDM (ethylene propylene diene rubber), elastomer or the like).

  The exterior member 20 has one end portion fixed to the portion of the wire harness WH that is routed in the vehicle body 2 by being wound with a tape T or the like, and a vehicle body that will be described later on a portion near the one end portion. The attachment member 30 is fixed. Further, the other end portion of the exterior member 20 is fixed by being wound with a tape T or the like around a portion of the wire harness WH that is routed in the door 6 (herein, in the protector P described later), and the door together with the wire harness WH. 6 can be moved forward and backward (see FIG. 3).

  The vehicle body mounting member 30 (also referred to as an edge protector) is a member that protects the wire harness WH (exterior member 20) inserted through the through hole 2h from the peripheral edge (edge) of the through hole 2h (FIGS. 2 to 2). 5). Here, the vehicle body attachment member 30 fixes the exterior member 20 to the vehicle body 2. The vehicle body attachment member 30 is fixed to a part of the exterior member 20 near one end, and is attached to the peripheral portion of the through hole 2 h of the vehicle body 2. More specifically, the vehicle body attachment member 30 is formed so as to be attachable to the vehicle body 2 by being pressed against a through hole portion 2 h formed in the vehicle body 2. Here, it is assumed that the through-hole portion 2h is formed in a plate-like portion substantially orthogonal to the front-rear direction of the vehicle body 2 and penetrates in the front-rear direction. The vehicle body attachment member 30 includes an insertion portion 34, a plurality of locking portions 35, a presser portion 36, and an uneven fitting portion 38.

  The insertion portion 34 can be inserted into the through-hole portion 2h of the vehicle body 2 and is formed in a cylindrical shape that opens on both axial sides thereof. More specifically, the insertion part 34 is set to be slightly smaller than the through-hole part 2h with an outer shape (rectangle with a rounded cross-sectional view angle) corresponding to the through-hole part 2h. Here, the insertion portion 34 is inserted into the through-hole portion 2h toward the front of the vehicle body 2 (hereinafter, the insertion direction S) along the penetration direction of the through-hole portion 2h. In the following description, the insertion direction S of the vehicle body attachment member 30 may be used as the direction of each member according to the insertion direction S in the attachment form with respect to the vehicle body 2. That is, the insertion direction S refers to a relative direction in the relationship between the through-hole portion 2 h of the vehicle body 2 and the vehicle body attachment member 30. The inner peripheral portion of the insertion portion 34 has a shape corresponding to the outer shape of the exterior member 20 (the outer peripheral shape of the mountain portion), and is set slightly larger than the outer shape of the exterior member 20.

  At the distal end portion of the insertion portion 34, there is a locking portion 35 that can be locked from the front side in the insertion direction S with respect to the peripheral portion of the through-hole portion 2h in a state where the insertion portion 34 is inserted into the through-hole portion 2h. Is provided. The locking portions 35 are formed so as to protrude outward from a plurality of circumferential positions of the insertion portion 34 (here, four positions at equal intervals), and are respectively inserted in the insertion direction S with respect to the peripheral portion of the through-hole portion 2h. It 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 through-hole portion 2h, the locking portion 35 comes into contact with the peripheral edge of the through-hole portion 2h so that the insertion portion 34 or the locking portion 35 itself It is elastically deformed to the inner peripheral side of the insertion portion 34, elastically returns to the outer peripheral side at a position over the through-hole portion 2h, and is locked to the peripheral portion of the through-hole portion 2h.

  The presser portion 36 is provided continuously with the proximal end portion of the insertion portion 34 and is formed in a hook shape projecting to the outer peripheral side thereof. More specifically, the outer peripheral shape of the pressing portion 36 is formed larger than the through-hole portion 2h.

  And when the insertion part 34 is inserted in the through-hole part 2h, the latching | locking part 35 will latch from the insertion direction S front side with respect to the peripheral part of the through-hole part 2h, and the holding | suppressing part 36 will pass through-hole part 2h. The vehicle body mounting member 30 is fixed to the vehicle body 2 with the peripheral portion of the through hole 2h being sandwiched between the locking portion 35 and the pressing portion 36. .

  The concave / convex fitting portion 38 is a portion that is positioned so as not to be relatively movable in the axial direction of the exterior member 20 with respect to the exterior member 20 disposed in the insertion portion 34 (and the pressing portion 36). Here, the concave / convex fitting portion 38 is formed so as to be able to be fitted to the concave / convex outer shape of the corrugated tube as the exterior member 20. More specifically, the concave / convex fitting portion 38 is formed in a convex line extending in the circumferential direction protruding from the inner peripheral surface of the insertion portion 34 toward the inner peripheral side, and the valley of the exterior member 20 in the penetration direction of the insertion portion 34. A plurality are provided at intervals corresponding to the portions.

  The vehicle body attachment member 30 is configured by combining a pair of substantially U-shaped members (here, U-shapes having different lengths of opposing pieces) (see FIG. 5). Here, the vehicle body mounting member 30 is formed at one end of each of the abutting portions of the pair of substantially U-shaped members, and at the other end, and the locking portion 31 is locked. And a possible locked portion 32. More specifically, the locking portion 31 protrudes from the distal end portion of the insertion portion protruding from one end portion of the U-shaped member to the inner peripheral side of the U-shaped member, and gradually increases from the distal end side toward the proximal end side. This is a portion having a locking claw 31a formed in a substantially triangular shape in sectional view in which the protruding dimension is increased. The locking claw 31a has a locking surface facing the proximal end side. Moreover, the to-be-latched part 32 is formed in the concave shape opened in two places, the other end surface and inner peripheral surface of a U-shaped member. The locked portion 32 can be inserted into the locking portion 31 through an opening that opens at the other end surface of the U-shaped member. When the pair of U-shaped members are brought into contact with each other and the locking portion 31 is inserted into the locked portion 32, the locking surface of the locking claw 31a is the opening on the inner peripheral side of the locked portion 32. Abuts against the opening edge of each other. Thereby, the latching | locking part 31 latches to the to-be-latched part 32, and a pair of substantially U-shaped member is united. That is, by combining the pair of substantially U-shaped members with the exterior member 20 sandwiched therebetween, the uneven fitting portion 38 is fitted to the outer peripheral portion of the exterior member 20, and the vehicle body mounting member 30 is The member 20 is mounted so as not to be relatively movable in the axial direction of the exterior member 20. As a result, the wire harness WH is inserted into the insertion portion 34, and the wire harness WH covered with the exterior member 20 is in the through hole of the vehicle body 2 in a state where the vehicle body attachment member 30 is attached to the vehicle body 2. It is routed inside and outside through part 2h. The vehicle body mounting member 30 is formed such that a pair of substantially U-shaped members are connected to each other by hinges so that the pair of substantially U-shaped members can be opened and closed, and the other butted ends can be engaged with each other. Also good.

  And the vehicle body attachment member 30 is attached with respect to the peripheral part of the through-hole part 2h in the attitude | position where the exterior member 20 becomes flat along an up-down direction. As a result, the longitudinal direction of the cross-sectional view with higher rigidity of the exterior member 20 is substantially along the vertical direction, and the sagging is more reliably suppressed, and the bending of the wire harness WH covered by the exterior member 20 in the vertical direction is suppressed. be able to. Further, the vehicle body attachment member 30 is fitted into a through-hole portion 2h formed in a part below the part to which the opening degree restriction part 3 in the vehicle body 2 is connected, whereby the vehicle body of the opening degree restriction part 3 is obtained. It is attached to the vehicle body 2 at a position below the side connecting portion.

  But the vehicle body attachment member 30 is not restricted to the said shape. For example, the vehicle body mounting member 30 is maintained in the combined state by being fitted into the through-hole portion 2h in a state where the locking portion 31 and the locked portion 32 are omitted and a pair of substantially U-shaped members are abutted. May be used. Further, a flat elongated portion in which the portion for positioning the wire harness WH (an alternative portion of the concave-convex fitting portion 38) protrudes from the proximal end portion of the pressing portion 36 to the rear side in the insertion direction S along the insertion direction of the insertion portion 34. It may be formed in a rectangular shape. That is, the rear portion of the exterior member 20 disposed in the insertion portion 34 is fixed to the positioning portion by being taped together or fastened with a tie band, etc. Thus, the insertion portion 34 can be positioned in the penetrating direction. The tie band refers to a member that can adjust and maintain the circumferential dimension of the annular body in stages. When employing such a positioning portion, the vehicle body attachment member may be integrally formed by injection molding as a whole.

  The protector P is disposed in the door 6 and has a cylindrical insertion port portion 52 into which a part including the other end portion of the exterior member 20 is inserted, and the protector P of the exterior member 20 inserted from the insertion port portion 52. It is a member that accommodates the wire harness WH extending from the other end in a state having a marginal space that can be bypassed by the wire harness (see FIG. 3). Moreover, the protector P protects the wire harness WH accommodated in an inside from a peripheral member. The protector P has a housing part 40 and a guide part 50. More specifically, the protector P guides the exterior member 20 that is inserted into the guide portion 50 through the insertion port 52 by the guide portion 50 toward the housing portion 40, and from the other end of the exterior member 20. It is a member that accommodates the extended wire harness WH in the accommodation space of the accommodation portion 40 and routes it outside, that is, in the door 6 through the outlet 44. 1 and 3 show a protector P in which the insertion port 52 and the outlet 44 penetrate in a direction substantially orthogonal to each other and are formed in a substantially L shape in a side view as a whole.

  Hereinafter, the protector P will be described in more detail by focusing on the configurations of the guide unit 50 and the storage unit 40. In the following description, the protector P is viewed from the front side of the door 6 and is viewed from the vehicle inner side in a state of being disposed in the door 6.

  The guide part 50 is a cylindrical part which has the insertion port part 52 and guides the displacement path | route of the part containing the other edge part in the exterior member 20 which covers the wire harness WH. The insertion port portion 52 is a portion including one end portion of the guide portion 50. The other end portion of the guide portion 50 is continuous with one end portion of the accommodating portion 40.

  More specifically, the guide portion 50 is formed in a substantially rectangular tube shape in cross-section extending substantially linearly, and a portion including the other end portion of the exterior member 20 along a substantially linear advance / retreat path. Guide is possible. And the guide part 50 abuts on the outer peripheral part of the exterior member 20 inserted through the insertion port part 52, thereby restricting the position of the exterior member 20 in the radial direction (mainly in the vehicle exterior direction) with respect to the central axis. But the guide part 50 should just be able to insert and guide the exterior member 20, and may be formed in cylindrical shapes, such as a cross sectional view substantially elliptical shape, circular shape, or a polygon.

  Here, the relationship between the guide part 50 and the exterior member 20 is demonstrated. The exterior member 20 has a portion near one end fixed to the vehicle body 2 via the vehicle body mounting member 30, and at least a part including the other end is in the guide portion 50 when the door 6 is open. The extension dimension is set long enough to be inserted. On the other hand, the guide portion 50 only needs to be able to regulate the position of the portion including the other end of the exterior member 20 that is advanced and retracted in the door 6 when the door 6 is opened / closed mainly in the vehicle interior / exterior direction. Here, in the closed state of the door 6, the extension dimension is set such that the other end of the exterior member 20 slightly protrudes into the accommodating portion 40. But the guide part 50 may be set to the dimension which is longer than the said dimension and can be accommodated to the other edge part of the exterior member 20 in the closed state of the door 6. FIG.

  Moreover, the insertion port part 52 is formed so that it may spread toward an outer peripheral side toward one edge part (refer FIG. 3, FIG. 4). Here, the insertion port portion 52 is formed so as to gradually expand toward one end portion in all directions substantially orthogonal to the extending direction.

  The accommodating part 40 is arranged in the door 6 in a row with the guide part 50, and accommodates the wire harness WH extending from the other end of the exterior member 20 inserted into the guide part 50 in a state having a marginal space. Part. The accommodating part 40 has an accommodating space including a marginal space. The accommodating portion 40 has an outlet 44 through which the wire harness WH is pulled out from the accommodating space into the door 6.

  More specifically, the accommodating portion 40 swells the wire harness WH extending from the other end of the exterior member 20 so that the intermediate portion is separated from the first path R1 and the first path R1. However, it is formed so that it can be accommodated so as to be able to absorb the extra length by being bent between the second path R2 (see FIG. 3).

  The storage portion 40 includes a first wall portion 41 and a second wall portion 42 that are opposed to each other with the storage space in a side view. The wire harness WH accommodated in the accommodation space is disposed close to the first wall portion 41 when passing through the first route R1 and close to the second wall portion 42 when passing through the second route R2. . That is, in a state where the wire harness WH passes through the first path R1, there is a margin space on the second wall portion 42 side of the wire harness WH. Each of the first wall portion 41 and the second wall portion 42 has one end continuous to the other end of the guide portion 50 and the other end continuous to the outlet 44. More specifically, the first wall portion 41 extends so as to connect the other end portion of the guide portion 50 and the outlet 44 of the housing portion 40 on the inner peripheral side of the protector P having a substantially L shape in side view. is doing. In addition, the second wall portion 42 is spaced from the first wall portion 41 so that the wire harness WH can be bent and deformed, and is on the outer peripheral side of the substantially L-shaped protector P in side view, and the other end of the guide portion 50. It extends so as to connect the section and the outlet 44.

  If it demonstrates in relation to the opening / closing operation | movement of the door 6, in the open state of the door 6, the accommodating part 40 will allow the wire harness WH extended from the other edge part of the exterior member 20 to leave a margin space in the 2nd wall part 42 side. It accommodates in the form which passes 1st path | route R1 opened (refer FIG. 1). Moreover, the accommodating part 40 accommodates the wire harness WH in the form which passes 2nd path | route R2 in the closed state of the door 6 (refer FIG. 3). That is, the accommodating part 40 accommodates the part pushed into the accommodating space of the wire harness WH by the closing operation of the door 6 from the open position to the closed position, and absorbs the surplus length.

  The accommodating portion 40 has an in-door positioning portion 46 that can fix the wire harness WH at the outlet 44. The door positioning portion 46 is formed in a shape in which the opening edge of the outlet 44 is partially extended (here, in an L shape in cross section). Then, the wire harness WH drawn through the outlet 44 is in contact with the inside of the in-door positioning portion 46 and is fastened together with a tape T or tie band and fixed (here, fixed with a tape T). ), Positioning in the door 6 is possible. Thereby, even if the wire harness WH on the vehicle body 2 side advances or retreats in the housing portion 40 during the opening / closing operation of the door 6, it is possible to prevent the wire harness WH routed in the door 6 from being pulled or loosened. Thus, the surplus length can be absorbed more reliably in the accommodation space.

  The structure for fixing the wire harness WH to the housing portion 40 is not limited to the in-door positioning portion 46, and a plurality of holes for inserting a tie band are formed in the in-door positioning portion extending in a wall shape from the outlet 44. The wire harness WH may be fastened and fixed by inserting the tie band into the hole.

  In addition, from the viewpoint of reducing the load applied to the wire harness WH, the preferable shape of the accommodating portion 40 is as follows. Hereinafter, the shapes of the first wall portion 41 and the second wall portion 42 in a side view will be described more specifically (see FIG. 3). That is, in the open state of the door 6, the first wall portion 41 has an intermediate portion between the other end portion of the exterior member 20 and the door positioning portion 46 in the wire harness WH, and the other end portion of the exterior member 20. It is formed so as to be capable of path regulation so as to be accommodated along a path parallel to the direction connecting the door positioning part 46. In addition, the second wall portion 42 is larger than the path through which the wire harness WH passes through the line along the penetration direction of the insertion port portion 52 and the line along the penetration direction of the outlet 44 through the door positioning portion 46. It is formed so that it can be controlled to be bent (with a small bending radius). Here, the 2nd wall part 42 is formed in the shape where a curved wall part connects the guide part side wall part along the penetration direction of the insertion port part 52, and the extraction side wall part along the penetration direction of the extraction opening 44. As shown in FIG. ing. The curved wall portion is formed so as to bulge by a size smaller than the diameter of the wire harness WH in a direction partially away from the guide portion 50.

  This protector P is partially or entirely (entirely shown in FIGS. 2 and 4) in a recess 7 h formed in the door inner panel 7 in the door 6, that is, between the door inner panel 7 and the trim 8. Be contained. More specifically, the protector P is disposed in the door 6 such that the guide portion 50 is positioned on the front end side of the door 6 with respect to the accommodating portion 40 and the outlet 44 faces the upper side of the door 6. . Note that the term “facing upward” is not limited to the form facing upward in the vertical direction, but includes a form inclining upward and facing upward.

  Further, the attachment position of the protector P will be described in relation to the attachment position of the vehicle body attachment member 30 with respect to the vehicle body 2. The vehicle body attachment member 30 and the protector P are opened by the exterior member 20 between the vehicle body 2 and the door 6. Each is attached to the vehicle body 2 and disposed in the door 6 so as to be bridged below the restriction portion 3. Here, the vehicle body attachment member 30 is attached to a portion of the vehicle body 2 below the portion connected to the opening degree restriction portion 3. Moreover, the protector P is arrange | positioned in the door 6 so that the insertion port part 52 may be located under the site | part connected with the opening degree control part 3 in the door 6 (door inner panel 7). The vehicle body attachment member 30 and the protector P are attached to the vehicle body 2 or disposed in the door 6 in a positional relationship facing each other in the insertion direction S (the front-rear direction of the vehicle body 2) when the door 6 is closed (FIG. 3). FIG. 4). And in the closed state of the door 6, the wire harness WH extended between the vehicle body 2 and the door 6 is extended substantially linearly.

  Here, the protector P has the fixing | fixed part 58 which can be fitted with respect to the hole formed in the door inner panel 7 (refer FIG.2, FIG.4, FIG.12). The fixing portion 58 is formed so as to be fitted into the hole portion by pressing the protector P toward the vehicle inner side against the door inner panel 7 (in a direction in which the guide portion 50 is accommodated in the concave portion 7h). Yes. For example, the fixed portion 58 has a base shaft portion that protrudes from the side surface of the protector P, and a latching portion that is formed so as to expand from the distal end portion to the outer peripheral side and elastically deformable on the inner peripheral side. it can. Here, the fixing part 58 is provided in two places so that it may protrude from the insertion port part 52 and the accommodating part 40 of the guide part 50 among the one side surfaces of the protector P, respectively. More specifically, the fixing portion 58 protrudes toward the vehicle outer side from the side surface on the vehicle outer side of the protector P disposed in the recess 7h.

  When the fixing portion 58 is inserted into the hole formed in the door inner panel 7, the locking portion comes into contact with the peripheral edge of the hole and elastically deforms toward the inner peripheral side. It elastically returns to the outer peripheral side and engages with the peripheral edge of the hole from the outside of the vehicle. Thus, according to the protector P that can be fixed to the door inner panel 7 by the fixing portion 58, it can be easily fixed by simply pressing against the door inner panel 7.

  But the structure for fixing the protector P with respect to the door inner panel 7 should just be arrange | positioned in the door 6 with said attitude | position and position, and another fixing structure may be employ | adopted. For example, the protector P may have a shape that can be fixed to the door inner panel 7 by screwing, bolting, stud bolting, bracket fixing, or the like.

  The protector P having the housing portion 40 and the guide portion 50 can employ a configuration in which, for example, a concave first member P1 and a lid-like second member P2 are combined (see FIGS. 2 and 4). ). In addition, in FIG. 1, FIG. 3, the protector P which abbreviate | omitted the 2nd member P2 is shown. The first member P1 and the second member P2 are provided with a plurality of locking portions on one side and a plurality of locked portions on which the locking portions can be locked on the other side in order to maintain the combined state. A part may be provided. The locking portion and the locked portion are omitted in the drawing. And the protector P can be comprised by manufacturing and uniting the 1st member P1 and the 2nd member P2 by injection molding etc., respectively. The protector P may be configured by a combination of concave members or the like, or may be configured as a concave shape as a whole and 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 connected to the other end side of the guide portion 50. May be arranged.

  Moreover, the protector P should just be able to accommodate the wire harness WH inserted from the insertion port part 52 with an allowance space, and is not restricted to the said shape. For example, the wire harness WH is wound and accommodated in a ring shape, the shape having an accommodating portion that can be bypassed by changing the diameter of the ring portion, the guide portion is configured only by the insertion port portion 52, and the other end portion of the exterior member 20 A shape or the like in which a portion that guides a part of the advancing / retreating route including “” may be adopted.

  The grommet 60 has a shielding part 62, a cylindrical part 64, a water stop rib 65, and a flange part 66. Water, dust and dirt are introduced into the door 6 through the introduction opening part 6h and the insertion opening part 52 of the protector P. It is a member for suppressing sand and the like from entering (see FIGS. 6 and 7). The grommet 60 is integrally formed by, for example, injection molding a rubber material as a whole, and is more flexible than the protector P.

  The cylindrical portion 64 is a portion that covers the insertion port portion 52 of the guide portion 50. The cylindrical portion 64 is formed in a cylindrical shape (in this case, a cylindrical shape having a substantially rectangular shape in cross section) corresponding to the external shape of the insertion port portion 52, and the size thereof is the same as the external shape of the insertion port portion 52. It is set smaller (slightly smaller here). That is, the cylindrical portion 64 is covered by the insertion port portion 52 in a state where it is in overall contact with the outer peripheral surface of the insertion port portion 52 in the circumferential direction. Here, since the insertion port portion 52 is formed in a shape that expands to the outer peripheral side at one end portion, the internal space of the cylindrical portion 64 corresponds to the shape of one end portion of the insertion port portion 52. A part of the central axis extends to the outer peripheral side.

  When the trim 8 is attached to the door inner panel 7, the cylinder portion 64 covered with the insertion opening 52 is sandwiched between the door inner panel 7 and the trim 8 by the introduction opening 6 h and is both inside and outside the vehicle. It will be in the state which touched the direction. But the cylinder part 64 does not ask | require the presence or absence of the contact with respect to the door inner panel 7 and the trim 8, but it contributes also to rattling suppression of the protector P by contacting.

  The inner peripheral portion of the cylindrical portion 64 is provided with a water stop rib 65 that protrudes toward the inner peripheral side and is formed in a convex line along the circumferential direction (see FIG. 7). Here, a pair of water-stopping ribs 65 are provided at intervals in the central axis direction of the cylindrical portion 64. The water stopping rib 65 is formed in a shape that is convex in a substantially arc shape in cross section. For example, the protruding dimension of the water stop rib 65 may be set to 0.1 to 2.0 mm. And in the state where the cylinder part 64 was covered by the insertion port part 52, the rib 65 for water stop contacts with the outer peripheral surface of the insertion port part 52, and is larger than the force which the cylinder part 64 clamp | tightens the insertion port part 52. Tightened with force.

  The water stopping rib 65 may be omitted. That is, when the cylindrical portion 64 is covered with the insertion port portion 52, an effect of suppressing intrusion of water, dust, sand, and the like is obtained, and when the clamping force of the cylindrical portion 64 is sufficiently strong, The gap between the insertion port portion 52 and the outer peripheral portion can be made smaller to prevent entry of water, dust, sand, and the like.

  From the viewpoint of water stop, dustproof performance, etc., it is preferable that the cylindrical portion 64 is in close contact with the outer peripheral surface of the insertion port portion 52 over the entire circumferential direction. Here, at least a part of the insertion port portion 52 in the central axis direction is formed so that the outer peripheral portion is flat in the entire circumferential direction (see FIG. 12). That is, when the cylindrical portion 64 (preferably the water stop rib 65 provided on the cylindrical portion 64) is covered with a portion of the insertion port portion 52 whose outer peripheral portion is formed flat over the entire circumferential direction, The gap between the portion 64 and the insertion port portion 52 can be eliminated or made smaller.

  The said shape of the insertion port part 52 of the guide part 50 makes the 1st member P1 and the 2nd member P2 which comprise the protector P match | combine the end parts with the form which an outer peripheral surface becomes substantially flush, and unite | combining them. It is formed. As the shape of the abutting portion of the first member P1 and the second member P2, a form in which flat end surfaces are abutted with each other (see FIG. 8), a form in which end parts having corresponding irregularities are abutted, and the like can be adopted. In FIG. 9, the convex portion of the first member P1 overlaps the convex portion of the second member P2 from the outer peripheral side. In FIG. 10, the convex portion of the second member P2 is on the outer peripheral side of the convex portion of the first member P1. The overlapping shape is shown. According to the protector in which the butt end portion shown in FIGS. 9 and 10 is formed in the corresponding uneven shape, it is possible to more effectively suppress intrusion of water, dust, sand and the like from the butt portion.

  The shielding part 62 has an insertion opening 61 through which the exterior member 20 inserted into the insertion opening 52 of the protector P can be inserted, and is a member for closing a gap between the insertion opening 52 and the exterior member 20 ( (See FIGS. 6 and 7). More specifically, the shielding part 62 is formed in a shape protruding from the entire one end of the cylindrical part 64 toward the inner peripheral side. The shielding part 62 is formed in a flat shape along a direction substantially orthogonal to the central axis of the cylindrical part 64. Further, the shielding part 62 is provided side by side in the circumferential direction with a plurality of slits formed from the opening edge part of the insertion opening part 61 toward the outer peripheral side, and each tip part opens the opening edge part of the insertion opening part. A plurality of shielding pieces 63 are formed. That is, the shielding piece 63 has a base end portion that is continuous with one end portion of the cylindrical portion 64 and a distal end portion that is a free end. Since the plurality of shielding pieces 63 can be elastically deformed independently of each other, they are elastically deformed according to their respective contact states with respect to the exterior member 20 to follow the advance / retreat operation of the exterior member 20 more flexibly. As described above, the grommet 60 is formed by molding a rubber material. Due to the shape and material described above, the opening edge portion of the insertion opening 61 of the shielding portion 62 is easily elastically deformed in the direction of the central axis of the cylindrical portion 64.

  Further, the insertion opening 61 of the shielding part 62 is set so as to open the same as or smaller than the cross-sectional shape of the exterior member 20. Here, the insertion opening 61 is set to be slightly smaller than the cross-sectional shape of the exterior member 20. That is, the front end portions of the plurality of shielding pieces 63 are pressed against the outer peripheral portion of the exterior member 20 inserted through the insertion opening 61 and maintained in an elastically deformed state. Further, the plurality of shielding pieces 63 are elastically deformed in the direction of the central axis of the cylindrical portion 64 with the forward and backward movement of the exterior member 20 inserted through the insertion opening 61, and the distal ends are formed on the exterior member 20. The state in contact with the outer periphery is maintained. And the state where each front-end | tip part of the some shielding piece 63 contacted with respect to the outer peripheral part of the exterior member 20 penetrated by the insertion opening part 61 is maintained, and the insertion port part 52 of the protector P, and an exterior member The gap with 20 is closed.

  But the shielding part 62 should just be able to block the clearance gap between the insertion port part 52 and the exterior member 20, and is not restricted to the shape which has the some shielding piece 63. FIG. For example, the shielding portion may be formed in a shape that protrudes from the one end portion of the cylindrical portion 64 toward the inner peripheral side and continues in the circumferential direction. In this case, the insertion opening of the shielding portion may be set to have the same shape and size as the outer shape of the exterior member 20 (the mountain portion).

  The flange portion 66 is a portion that is formed in a flange shape that extends from the outer peripheral portion of one end portion of the cylindrical portion 64 to the outer peripheral side, and covers the introduction opening 6h of the door 6 (see FIGS. 6 and 7). The flange 66 has a shape corresponding to the introduction opening 6h formed inside the recess 7h and the trim 8 of the door inner panel 7, and is formed larger than the introduction opening 6h. More specifically, the flange portion 66 is set to a size that covers the introduction opening 6 h and overlaps the peripheral edge portion constituted by the door inner panel 7 and the trim 8 from the front end side of the door 6. .

  The collar portion 66 is provided with a first door contact portion 66a and a second door contact portion 66b. The first door contact portion 66 a and the second door contact portion 66 b are portions that are in close contact with the peripheral edge portion of the introduction opening 6 h of the door 6 from the front end side of the door 6. More specifically, the first door contact portion 66a is a ridge along the peripheral edge portion of the introduction opening 6h that protrudes from the flange portion 66 in a direction from one end portion of the cylindrical portion 64 toward the other end portion. Is formed. Further, the second door contact portion 66b extends from one end portion of the tubular portion 64 to the other end portion along a peripheral edge portion of the introduction opening 6h from a portion of the flange portion 66 on the outer peripheral side of the first door contact portion 66a. It is formed in the shape of an umbrella that protrudes while expanding toward the outer periphery.

  The first door contact portion 66a abuts along the peripheral edge portion of the introduction opening 6h while the cylindrical portion 64 is put on the insertion port portion 52 of the protector P disposed on the door 6, and the second door. The close contact portion 66b is elastically deformed so as to expand to the outer peripheral side, and is brought into surface contact with the peripheral portion of the introduction opening 6h along the peripheral portion on the outer peripheral side of the first door close contact portion 66a. The first door contact portion 66a and the second door contact portion 66b are fixed at a fixed position with respect to the guide portion 50 by the force with which the cylindrical portion 64 tightens the insertion port portion 52, and are arranged at the peripheral portion of the introduction opening 6h. It is pressed against. Thereby, the introduction opening 6h of the door 6 is shielded.

  However, the grommet is not limited to the shape described above. Hereinafter, the grommet 160 which concerns on a modification is demonstrated (refer FIGS. 11-13). Parts of the grommet 160 having the same shape as the grommet 60 are given the same reference numerals.

  The grommet 160 has a covering opening 169 (see FIGS. 11 and 12). The opening portion 169 for covering is a portion for improving workability when the grommet 160 is attached to the insertion opening 52 of the protector P. In the grommet 160, the covering opening 169 is formed by abutting a pair of butted end portions 169a and 169b along at least the tube portion 164 along the central axis direction of the tube portion 164. FIG. 11 shows an example in which the covering opening 169 is formed over the entire grommet 160 in the central axis direction of the cylindrical portion 164. But the opening part for covering may be formed in the part of the other edge part side from the collar part in the cylinder part 164. FIG. Even in this case, the covering opening portion is formed by being cut from the other end portion so that the other end portion of the cylindrical portion 164 is cut open.

  The grommet 160 can be opened and widened by separating the pair of butt end portions 169a and 169b at the position of the covering opening portion 169. That is, when the grommet 160 is attached to the insertion port portion 52 of the protector P, the insertion port portion 52 is inserted into the cylindrical portion 164 through the opening portion opened at the other end of the cylindrical portion 164 and the covering opening portion 169. Accommodate. Thereby, the mounting workability with respect to the protector P of the grommet 160 can be improved.

  Moreover, the opening part 169 for covering is formed in the site | part in the vehicle interior / exterior direction with respect to the insertion port part 52 in the grommet 160 (here inside side). The opening portion 169 for covering is formed in a shape in which one butt end portion 169a located above is overlapped with the other butt end portion 169b located below from the outer peripheral side. In other words, the covering opening 169 is formed by cutting the cylindrical portion 164 into a shape that is inclined downward from the inner peripheral side toward the outer peripheral side. Thereby, penetration | invasion of water etc. can be suppressed, improving the mounting | wearing workability | operativity of the grommet 160 with respect to the protector P. FIG.

  The grommet 160 may be formed in the same manner as the grommet 60, and then a covering opening 169 may be formed using a cutting blade, or a mold corresponding to the shape of the grommet 160 having the covering opening 169. It may be molded using. And since the shape at the time of shaping | molding the grommet 160 formed in this way is maintained, it is suppressed that the covering opening part 169 opens with dead weight. The grommet 160 may be wound around the tape T after being attached to the insertion opening 52.

  However, the opening portion 169 for covering is not limited to the case where the opening portion 169 is formed in a portion of the cylindrical portion 164 located on the side of the insertion port portion 52 on the vehicle inner side. For example, the opening portion for covering may be formed in a portion located below the insertion port portion 52 in the cylindrical portion. Also in this case, the grommet mounting workability with respect to the protector P can be improved in the same manner as in the case where one of the butt end portions 169a positioned above is overlapped with the other butt end portion 169b positioned below from the outer peripheral side. While improving, the penetration | invasion of water etc. can be suppressed.

  The grommet 160 has a positioning hole 168 (see FIGS. 12 and 13). The positioning hole portion 168 is a portion for suppressing the displacement of the cylindrical portion 164 with respect to the insertion port portion 52 and maintaining the state where the cylindrical portion 164 is covered by the insertion port portion 52. The positioning hole 168 is formed in the cylindrical portion 164 in a hole shape into which the fixing portion 58 is inserted in a state where the cylindrical portion 164 is covered by the insertion port portion 52. More specifically, the peripheral portion of the positioning hole 168 is fixed to the fixing portion 58 in a state where the base shaft portion that protrudes from one side surface of the insertion port portion 52 of the protector P in the fixing portion 58 is inserted into the positioning hole 168. The cylindrical portion 164 is prevented from being displaced by abutting on the base shaft portion in a direction substantially orthogonal to the axial direction of the base shaft portion. The size of the positioning hole 168 may be set to be approximately the same as the outer shape of the cross-sectional shape of the base shaft portion of the fixed portion 58.

  When the cylindrical portion 164 is put on the insertion port portion 52 in a state where the fixing portion 58 is inserted into the positioning hole 168, the cylindrical portion 164 can be prevented from being detached from the insertion port portion 52. Further, when the fixing portion 58 inserted into the positioning hole portion 168 is fitted into the hole portion formed in the door inner panel 7, the space between the door inner panel 7 and the side surface of the protector P (insert port portion 52). In this state, a part of the cylindrical portion 164 of the grommet 160 formed of a rubber material is interposed. Thereby, the noise by the rattling of the protector P with respect to the door inner panel 7 by the vibration etc. at the time of opening and closing of the door 6 and vehicle travel can be suppressed.

  Note that the positioning hole may be provided in the grommet 60 where the covering opening is not formed (not shown). In this case, the grommet 60 is more reliably positioned with respect to the insertion opening 52.

  Moreover, the rib for water stop may be provided in the cylinder part 164 of the grommet 160 shown in FIGS. 11-13 (illustration omitted). That is, by winding the cylindrical portion 164 with the tape T, the water stopping rib can be brought into close contact with the outer peripheral surface of the insertion port portion 52 by the tightening force.

  Further, the grommet 60 has been described so far with the example in which the grommet 60 has the flange portion 66, but the flange portion 66 may be omitted. That is, the cylindrical portion 64 is covered with the insertion opening 52, so that intrusion of water, dust, sand and the like into the protector P can be suppressed, and when the cylindrical portion 64 is covered with the guide portion 50, the introduction opening 6h. Even when the gap between the guide portion 50 is shielded by the cylinder portion 64 or when the gap between the cylinder portion 64 and the peripheral edge of the introduction opening 6h and the cylinder portion 64 is sufficiently small, Intrusion of dust and sand is suppressed. But when the clearance gap between the opening edge part of the introduction opening part 6h and the cylinder part 64 is large, it is preferable that the collar part 66 is provided.

  The wire harness routing structure 10 is a modularized assembly of the wire harness WH, the exterior member 20, the vehicle body mounting member 30, the protector P, and the grommet 60 that are routed from the vehicle body 2 into the door 6 before the vehicle is assembled. It is good to keep. That is, the exterior member 20 is covered with the wire harness WH, and the vehicle body attachment member 30 is attached to a portion near one end of the exterior member 20, and one end and the other end of the exterior member 20 are connected to each part. A wire T is wound around the extended wire harness WH and fixed. Further, the grommet 60 is attached to the insertion opening 52 of the protector P. A portion including the other end of the exterior member 20 is disposed in the guide portion 50 of the protector P in a state where the insertion opening 61 of the grommet 60 is passed through, and extends from the other end of the exterior member 20. The wire harness WH may be accommodated in the accommodating portion 40 and the portion pulled out from the outlet 44 may be fixed to the in-door positioning portion 46 by tape T winding.

  So far, the example in which the water stop rib 65 is provided in the grommet 60 has been described. However, in order to improve the waterproof and dustproof performance between the insertion port portion 52 and the cylindrical portion 64, the cylindrical portion 64 or the insertion portion is inserted. At least one of the mouth portions 52 is formed in a convex line extending in the circumferential direction protruding toward the inner peripheral side or the outer peripheral side, and the water stop is in contact with the outer peripheral surface of the insertion port portion 52 or the inner peripheral surface of the cylindrical portion 64. What is necessary is just to have a rib for use. FIG. 14 shows an example in which a water stop rib 255 is provided in the insertion port 252 of the guide 250. In this case, the water stop rib 255 is in close contact with the inner peripheral portion of the cylindrical portion 264 of the grommet 260 formed of a rubber material. That is, the water stop rib 255 is a portion for improving the adhesion between the outer peripheral portion of the insertion port portion 252 and the cylindrical portion 264 of the grommet 260. In addition, a water-stopping rib may be provided in both the insertion opening and the grommet tube.

  Moreover, although the wire harness wiring structure part 10 was demonstrated to the example applied to the door 6 as a front side door until now, it is applicable also to the other door connected with the vehicle body 2 by the hinge. For example, when applied to a rear side door, the wire harness WH is bridged between a center pillar (a pillar between the front side door and the rear side door) and the rear side door. That is, a hole is formed in the center pillar, and the vehicle body attachment member 30 is attached thereto.

  According to the wire harness wiring structure unit 10 according to the first embodiment, the tubular exterior member 20 having higher rigidity than the wire harness WH covers a portion of the wire harness WH that is bridged between the vehicle body 2 and the door 6. At the same time, the vehicle body mounting member 30 is fixed to a part of the exterior member 20 near one end. For this reason, it is possible to smoothly introduce the wire harness WH between the vehicle body 2 and the door 6 into the guide portion 50 while suppressing the drooping and bending of the wire harness WH. Further, the guide portion 50 disposed in the door 6 guides a part of the displacement path including the other end of the exterior member 20 inserted through the insertion port portion 52, and is connected to the guide portion 50 in the door 6. In order to accommodate the wire harness WH extending from the other end of the exterior member 20 in a state having a marginal space that can be bypassed, the door 6 of the wire harness WH accompanying the opening / closing operation of the door 6 is accommodated. The advancing and retreating operations can be performed smoothly. In addition, the cylindrical portion 64 of the grommet 60 is put on the insertion port portion 52, the shielding portion 62 closes the gap between the insertion port portion 52 and the exterior member 20, and the flange portion 66 covers the introduction opening 6 h of the door 6. Intrusion of water, dust, sand and the like into the door 6 can be suppressed.

  In addition, the entire portion of the wire harness wiring structure 10 existing between the through hole 2 h of the vehicle body 2, the introduction opening 6 h of the door 6 and the insertion opening 52 of the guide 50 is covered with the grommet 60. Therefore, it contributes to the prevention of abnormal noise due to vibrations when the door 6 is opened and closed and when the vehicle is running.

  Further, the outer peripheral portion of the exterior member 20 moves back and forth in the protector P while being in contact with the shielding portion 62 located on the inner peripheral side from the insertion port portion 52 of the protector P. Since the grommet 60 is formed of a rubber material that is more flexible than the protector P, the sound generated at the time of contact can be reduced as compared with the case where the outer peripheral portion of the exterior member 20 contacts the insertion port 52.

  The shielding part 62 of the grommet 60 is provided side by side in the circumferential direction with a slit formed from the opening edge part of the insertion opening part 61 toward the outer peripheral side, and each tip part is an opening edge of the insertion opening part 61. A plurality of shielding pieces 63 are formed. For this reason, with respect to the operation in which the exterior member 20 inserted through the insertion opening 61 advances and retreats into the protector P through the insertion opening 52, the shielding portion 62 can be deformed in a more flexible manner. It is possible to suppress the intrusion of water, dust, sand, and the like into the door 6 while making the forward and backward movement of the wire harness WH accompanying the opening / closing operation into the door 6 smoother.

  Further, since the insertion opening 61 of the shielding part 62 is set to be smaller than the cross-sectional shape of the exterior member 20, a state in which the gap between the insertion port 52 of the protector P and the exterior member 20 is blocked when the door 6 is opened and closed. It can be maintained more reliably.

  In addition, since the insertion port portion 52 has at least a portion of the outer peripheral portion in the central axis direction formed flat over the entire circumferential direction, the inner peripheral portion of the cylindrical portion 64 is the outer periphery of the portion of the insertion port portion 52. By contacting the part, the gap between the cylinder part 64 and the insertion port part 52 can be made smaller, and intrusion of water, dust, sand and the like can be suppressed.

  Further, the vehicle body attachment member 30 is configured to be positioned by positioning the one end side portion of the exterior member 20 covering the wire harness WH by the concave / convex fitting portion 38 and simply pressing the through-hole portion 2h from one side. Therefore, the wire harness WH can be easily routed to the vehicle body 2 side.

  Moreover, since the wire harness wiring structure part 10 has wired the wire harness WH between the door inner panel 7 and the trim 8, it can save the effort which inserts and wires the wire harness WH through a 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.
