Description

  The present invention relates to a protective material for a flat harness and a flat harness that is externally covered with the protective material for a flat harness, and more specifically, the protective material for a flat harness can be easily externally attached to the flat harness. The flat harness can be reliably protected without being exposed from the material.

2. Description of the Related Art Conventionally, a wire harness routed in an automobile is externally covered with a protective material such as a corrugated tube made of synthetic resin in order to prevent damage to an electric wire due to interference with peripheral components.
The corrugated tube is a bellows-like cylindrical body in which annular crests and troughs are alternately provided in the axial direction, and can be freely bent according to the bending when it is routed at a bent portion. Therefore, it is effective as a protective material for the wire harness.
Further, by forming the slit 2 as shown in FIG. 12 in the longitudinal direction of the corrugated tube 1, so-called split-shaped corrugated tube 1, the slit 2 is opened and the direction perpendicular to the wire harness W / H is perpendicular. The corrugated tube 1 can be easily attached to the wire harness W / H simply by covering the corrugated tube 1 from the side (see JP-A-11-289630).

On the other hand, a harness routed between a movable member such as a sliding door and the vehicle body is routed with an extra length so that it is folded back in a U shape between the vehicle body and the movable member. Can be followed. As described above, a flat harness in which a strip-shaped conductor is covered with an insulating resin material has been widely used as a harness that is routed in a site that needs to bend and extend repeatedly following the movement of the movable member. .
However, when the split-shaped corrugated tube is used as a protective material for such a flat harness, the slit of the corrugated tube is opened at the time of bending, so that the flat flat harness is easily exposed or dropped off. There is.
In order to prevent such a problem, it is necessary to add a mechanism for preventing the flat harness from being exposed and dropped, such as providing a lock on the slit of the corrugated tube, which increases the number of parts. There is a problem that assembly man-hours increase.
Furthermore, since the corrugated tube has a bellows shape in which the peaks and valleys are continuous as described above, the protective material is considerably larger than the flat harness inserted inside, between the sliding door and the vehicle body, etc. There is also a problem that it is difficult to route in a narrow space.

Japanese Patent Laid-Open No. 11-289630

  The present invention has been made in view of the above problems, and can easily prevent the flat harness from being exposed or dropped from the protective material while allowing the protective material to be easily packaged on the flat harness. The problem is that it can be protected with a minimum size.

In order to solve the above-mentioned problem, the first invention is made of a resin-made strip-like material having flexibility, and the first hinge part and the second part are provided at two places in the middle part in the width direction orthogonal to the length direction. The hinge portion extends continuously in the length direction, and is divided into three in the width direction by the first hinge portion and the second hinge portion, and the first folding portion, the center placement portion, and the second folding portion are Provided,
In a state where the flat harness is placed on the central placement portion, the first folding portion is folded and covered with the flat harness, and the second folding portion is folded and covered with the first folding portion. A protective material for flat harnesses is provided.

As described above, the first hinge portion and the second hinge portion are continuously extended in the length direction at two positions in the middle portion in the width direction of the belt-shaped material, and the width direction is determined by the first and second hinge portions. The three-folded flat harness protective material is composed of a first folding part, a central mounting part, and a second folding part. Therefore, a flat harness is mounted on the central mounting portion, and the first folding portion and the second folding portion are sequentially folded from both sides of the long side of the flat harness. The exterior to the harness is completed, and the outer surface of the flat harness can be completely covered with the flat harness protective material.
In addition, when the flat harness externally covered with the protective material for the flat harness is bent following the movement of a movable member such as a sliding door, the surfaces of the first and second folding parts are bent toward the internal flat harness by bending stress. Since it is in a pressed state, it is also possible to prevent the flat harness from being exposed or falling off due to the opening of the first and second folding parts.

Furthermore, by making the protective material for flat harnesses into a folding structure as described above, the flat harness can be thinned along the outer flat harness, and the periphery of the flat harness can be protected with a minimum size. Therefore, even in a narrow routing space, it is possible to easily route without interfering with peripheral parts.
In addition, even if the flat harness mounted in a center mounting part is one sheet, you may be in the state which laminated | stacked several sheets, and the width direction of a 1st, 2nd hinge part is sufficient according to the number of flat harnesses mounted. The length may be adjusted as appropriate.

In addition, as described above, by forming the flat harness protective material from a flexible resin strip, the flat harness covered with the flat harness protective material is connected to a movable member such as a slide door and the vehicle body. Even when it is bridged between the two, the bending / extending operation can be smoothly repeated following the movement of the movable member.
The resin for forming the belt-shaped material is not particularly limited as long as it has flexibility, for example, rubber such as ethylene-propylene rubber (EPDM), various elastomers, and the like can be used. In particular, an olefin elastomer is preferably used.
Also, the widths of the first folding part, the center mounting part and the second folding part may all be equal, or the width of the first folding part may be slightly smaller than the width of the second folding part. Good.

Furthermore, in order to fold the first and second folding portions more smoothly, the first and second hinge portions may be formed in a thin shape.
Further, the width of the first hinge part interposed between the first folding part and the central mounting part is at least longer than the thickness of the flat harness so that the flat harness can be sandwiched between the first folding part and the central mounting part. On the other hand, the width of the second hinge part interposed between the second folding part and the central mounting part is such that the flat harness and the first folding part are sandwiched between the second folding part and the central mounting part. It has at least a length equal to or more than the thickness of the flat harness and the first folding part so that it can be inserted.

Further, the first hinge part and the second hinge part are formed of a resin having flexibility in comparison with the first and second folding parts and the central mounting part, or the first hinge part, It is preferable that the second hinge part and the center mounting part are formed of a resin having flexibility as compared with the first and second folding parts.
As described above, the first and second hinge portions in the protective material for the flat harness are molded with a resin that is more flexible than the first and second folding portions and the central mounting portion, or the first hinge portion, By forming the 2 hinge part and the central mounting part with a resin having flexibility as compared with the first and second folding parts, the protective material for the flat harness can be bent more easily, and the sliding door or the like can be moved. The followability to the member can be further improved. Moreover, by setting it as the said structure, folding of the said 1st, 2nd folding part becomes easy, and the exterior workability | operativity to a flat harness can be improved further.

  As the resin forming the first and second hinge parts, for example, a resin whose hardness is lowered by changing the blending ratio of the olefin-based elastomer forming the first and second folding parts and the central mounting part is used. Preferably used. Thus, the said protective material for flat harnesses which consists of two types of resin from which hardness differs can be shape | molded, for example by two-color extrusion molding.

  In addition, the first hinge portion and the second hinge portion may have a curved or inclined cross section perpendicular to the longitudinal direction, or a curved shape having a corrugated inner surface or the entire length in the longitudinal direction. It is preferable to be inclined.

As described above, when the cross section perpendicular to the length direction is curved in the entire length in the length direction of the first hinge portion and the second hinge portion, the flexibility at the time of bending of the protective material for the flat harness is increased. Can do.
Further, as described above, when the cross section perpendicular to the length direction is inclined in the entire length in the length direction of the first hinge portion and the second hinge portion, the length in the width direction of the protective material for the flat harness is increased. It can be kept short.
Further, when the cross section perpendicular to the length direction of the first hinge part and the second hinge part in the length direction is a curved or inclined shape having a corrugation on the inner surface side, a protective material for a flat harness When the flat harness externally mounted is bent, the shift generated between the inner peripheral surface and the outer peripheral surface is easily absorbed, and a smoother bending operation is possible.

Further, in a state where the first and second folding parts are folded on the central mounting part, in a cross section orthogonal to the length direction, a curved shape in which one surface side is a concave surface and the other surface side is a convex surface may be used.
That is, each of the first and second folding parts and the central mounting part has a flat harness mounted on the central mounting part so that a cross section perpendicular to the length direction is curved in the entire length in the length direction. In the state where the first and second folding portions are folded and placed, the curved surface has a concave surface on one side and a convex surface on the other side.
With this configuration, when the flat harness covered with the protective material for the flat harness is bent, the flat harness can be bent at a certain bending angle, and a smoother bending operation that follows the movement of the movable member is possible.
The radius of curvature of the curved shape of the cross section perpendicular to the length direction is the radius of curvature of the bent portion when the flat harness covered with the protective material for flat harness is bent between the fixed member and the movable member. Is preferably about twice as large.

  In addition, the required region of the band-shaped material that is externally folded and folded on a flat harness is further covered with a cylindrical boot formed of a resin harder than the band-shaped material, or the first folded portion and the surface thereof are covered. A leaf spring is interposed between the second folding parts, or a guide plate formed of a high-hardness resin is bonded to the outer surface of the central mounting part and / or the outer surface of the second folding part, which is the outer surface of the folded state. It is preferable.

When a flat harness covered with a protective material for a flat harness is bridged between a movable member such as a sliding door and a vehicle body and bent according to the movement of the movable member, for example, In order to prevent interference with a part, it may be necessary to regulate the bending angle of the flat harness in a predetermined region.
However, according to the said structure, the cylindrical boot, guide plate, or leaf | plate spring shape | molded with resin harder than the protective material for flat harnesses is suitably arrange | positioned in the area | region which needs to regulate the bending angle of a flat harness. As a result, the bending angle of the flat harness can be appropriately regulated, and the flat harness can smoothly follow the movement of the movable member, and interference between the flat harness and peripheral components can be effectively prevented.

  According to a second aspect of the present invention, there is provided a flat harness characterized in that the flat harness is sheathed with the protective material for a flat harness of the first aspect of the invention and wired in an automobile.

  In particular, the flat harness is routed between the sliding door and the vehicle body, and is bent according to the opening / closing operation of the sliding door. It is preferable that the tubular boot, the leaf spring, or the guide plate is attached to the harness protective material, and the tubular boot or the guide plate is provided with a slit or a thin portion in the length direction.

When the flat harness is routed between the sliding door and the vehicle body, the flat harness is curved following the opening / closing operation of the sliding door. In particular, when the sliding door is fully opened, the fixed end side of the flat harness with the vehicle body is greatly bent in the door opening direction, so that the flat harness may interfere with the vehicle body if the bending angle of the curved region is too large. Therefore, regulating the bending angle of the flat harness on the fixed end side with the vehicle body is important in terms of preventing interference with the vehicle body.
According to the above configuration, since the cylindrical boot, the leaf spring or the guide plate is attached to the protective material for the flat harness in the region where the bending angle needs to be regulated, the bending angle of the flat harness is appropriately regulated. Thus, the flat harness can smoothly follow the opening / closing operation of the slide door, and the interference between the flat harness and the vehicle body can be effectively prevented.

  In addition, as described above, the degree of restriction of the bending angle can be appropriately adjusted by providing the cylindrical boot or the guide plate with slits or thin portions in the length direction. In other words, in a region where it is necessary to sufficiently restrict the bending angle, the interval between the slits or thin portions provided in the length direction is widened, while in a region where the restriction of the bending angle may be relaxed, it is provided in the length direction. It is also possible to gradually increase the flexibility by narrowing the interval between the slits or the thin wall portion.

As described above, according to the present invention, the first hinge portion and the second hinge portion are continuously extended in the length direction at two locations in the intermediate portion in the width direction of the belt-like material, and the first and second Since the protective material for a three-fold flat harness comprising a first folding part, a central mounting part, and a second folding part, which is divided into three in the width direction by two hinge parts, a flat harness is attached to the central mounting part. And the exterior of the flat harness protective material to the flat harness is completed by a simple operation of sequentially folding the first and second folding parts from both sides of the long side of the flat harness. Can be completely covered with the flat harness protective material.
Further, when the flat harness externally covered with the protective material for the flat harness is bent following the movement of a movable member such as a sliding door, the surfaces of the first and second folding parts are bent by the internal flat harness side. Therefore, it is possible to prevent the flat harness from being exposed or falling off by opening the first and second folding parts.

  Furthermore, by making the protective material for flat harnesses into a folding structure as described above, the flat harness can be thinned along the outer flat harness, and the periphery of the flat harness can be protected with a minimum size. Therefore, even in a narrow routing space, it is possible to easily route without interfering with peripheral parts.

  In addition, as described above, by forming the flat harness protective material from a flexible resin strip, the flat harness covered with the flat harness protective material is connected to a movable member such as a slide door and the vehicle body. Even when it is bridged between the two, the bending / extending operation can be smoothly repeated following the movement of the movable member.

  Furthermore, as described above, the first and second hinge portions in the protective material for the flat harness are molded with a resin that is more flexible than the first and second folding portions and the central placement portion, or the first hinge portion. By forming the second hinge part and the central mounting part with a resin having flexibility compared to the first and second folding parts, the flat harness protective material can be bent more easily, such as a sliding door. The followability to the movable member can be further improved, the first and second folding parts can be easily folded, and the exterior workability to the flat harness can be further improved.

  Further, as described above, in the entire length in the length direction of the first hinge portion and the second hinge portion, if the cross section orthogonal to the length direction is curved, the flexibility when the protective material for the flat harness is bent is obtained. Can be increased. On the other hand, when the cross section orthogonal to the length direction of the first hinge portion and the second hinge portion is inclined, the length in the width direction of the protective material for the flat harness can be suppressed to be short. Furthermore, if the cross section orthogonal to the length direction of the first hinge portion and the second hinge portion is a curved shape or an inclined shape with a corrugation on the inner surface side, the flat harness sheathed with the protective material for the flat harness is bent. At this time, the deviation generated between the inner peripheral surface and the outer peripheral surface is easily absorbed, and a smoother bending operation is possible.

  Further, as described above, in the first and second folded states, when the cross section perpendicular to the length direction is a curved shape with the concave surface on one side and the convex surface on the other side, it is covered with a protective material for a flat harness. When the flat harness is bent, the flat harness can be bent at a certain bending angle, and a smoother bending operation following the movement of the movable member is possible.

  In addition, as described above, a cylindrical boot, a guide plate, or a leaf spring, which is molded with a resin having a higher hardness than the protective material for the flat harness, is appropriately disposed only in a region where the bending angle of the flat harness needs to be regulated. By making the flat harness smoothly follow the movement of movable members such as sliding doors, the bending angle of the flat harness can be properly regulated, effectively preventing interference between the flat harness and peripheral components. Can do.

Embodiments of the present invention will be described with reference to the drawings.
1 to 6 show a first embodiment of the present invention, in which a flat harness protective material 10 is externally mounted on a flat harness 20 that is routed between a slide door 30 and a vehicle body 31.
As shown in FIGS. 1 and 2, the flat harness protective material 10 is made of an olefin-based elastomer resin band-like material 11, and has a thin-walled shape at two locations in the middle in the width direction orthogonal to the length direction. The first hinge part 12 and the second hinge part 13 are continuously extended in the length direction, and the strip 11 is divided into three in the width direction by the first hinge part 12 and the second hinge part 13, A first folding part 14, a central mounting part 15, and a second folding part 16 are provided. The central placement portion 15 is a portion on which the flat harness 20 (one flat harness 20 in the present embodiment) is placed, and the first folding portion 14 is folded and placed on the central placement portion 15. A portion that covers the flat harness 20, the second folding portion 16, is a portion that is folded and covers the first folding portion 14. In addition, the 1st hinge part 12 and the 2nd hinge part 13 in this embodiment make the cross section orthogonal to this length direction curved shape in the full length of a length direction.
Moreover, although the 1st hinge part 12 and the 2nd hinge part 13 are formed from the olefin-type elastomer like the 1st folding part 14, the center mounting part 15, and the 2nd folding part 16, it changes a compounding ratio. Accordingly, the flexibility is enhanced as the hardness is lower than the hardness of the olefin-based elastomer that forms the first folding portion 14, the center placement portion 15, and the second folding portion.

Furthermore, the width of the first hinge portion 12 is longer than the thickness of the flat harness 20 so that the flat harness 20 can be sandwiched between the first folding portion 14 and the center placement portion 15. The width of the second hinge part 13 is equal to the thickness of the flat harness 20 and the first folding part 14 so that the flat harness 20 and the first folding part 14 can be sandwiched between the second folding part 16 and the central mounting part 15. It is longer.
In the present embodiment, the width of the central mounting portion 15 is approximately the same as the width of the flat harness 20 to be mounted, and the width of the first folding portion 14 is slightly smaller than the width of the second folding portion 16. .

  As described above, the present embodiment uses two types of olefin-based elastomers having different hardnesses between the first and second hinge portions 12 and 13 and the first and second folding portions 14 and 16 and the central mounting portion 15. The flat harness protective material 10 in the form is formed by two-color extrusion molding.

  As shown in FIG. 2 (A), the flat harness 20 is externally mounted on the flat harness 20 after the flat harness 20 is placed on the central placement portion 15 of the flat harness protector 10. As shown in FIG. 2 (B), the first folding part 14 is put on the flat harness 20 that is folded and placed, and further, as shown in FIG. 2 (C), the second folding part 16 is folded and the first folding part. 14 is completed.

Next, the flat harness 20 covered with the protective material 10 for flat harness is routed in a U shape between the slide door 30 and the vehicle body 31 of the automobile as shown in FIG. Specifically, the flat cable 20 is extended and wired in the horizontal direction, folded back into a U shape, provided with a bent portion 20a, and an extra length is provided between the vehicle body 31 and the slide door 30.
As shown in FIG. 3, the flat harness 20 covered with the flat harness protective material 10 is routed in a posture with the second folding portion 16 as the outer peripheral side, and as shown in FIG. The flat harness 20 covered with the protective material 10 is covered with a cylindrical boot 17 formed of a resin having a hardness higher than that of the belt-like material 11 in the fixed end region A with the vehicle body side support member 33. As a result, the bending angle of the region A after routing can be regulated. As shown in FIGS. 4 and 5, the cylindrical boot 17 is provided with slits 17 a in the length direction, and the distance between the slits 17 a is reduced as the distance from the fixed end with the vehicle body side support member 33 increases. Yes.

  The end portion 17b of the cylindrical boot 17 is fitted and fixed to the vehicle body side support member 33, and one end of the flat harness 20 covered with the flat harness protection material 10 is fixed to the vehicle body side support member 33 with a clip or the like. Then, a connector (not shown) connected to the terminal is connected to the connector of the wire harness terminal routed to the vehicle body 31, and the other end of the flat harness 20 is fixed to the sliding door side support member 32 with a clip or the like. The connector (not shown) is connected to the connector of the door harness terminal arranged in the slide door 30.

  P1 of FIG. 6 shows the fully open state of the slide door 30, and P3 shows the fully closed state. Moreover, P2 has shown the half-open state which is the intermediate | middle stage. The flat harness 20 covered with the flat harness protective material 10 follows the opening / closing operation of the slide door 30, and the bent portion 20 a also moves in the opening / closing direction of the slide door 30.

As described above, the first hinge portion 12 and the second hinge portion 13 are continuously extended in the length direction at two locations in the intermediate portion in the width direction of the belt-like material 11, and the first and second hinge portions 12 are extended. , 13 is a three-folded flat harness protective material 10 composed of a first folding section 14, a central mounting section 15, and a second folding section 16 that are divided into three in the width direction. The flat harness 20 is placed on the flat harness 20, and the first folding portion 14 and the second folding portion 16 are sequentially folded from both long side sides of the flat harness 20 to the flat harness 20 of the protective material 10 for flat harness. Thus, the outer surface of the flat harness 20 can be completely covered with the flat harness protective material 10.
Further, when the flat harness 20 covered with the protective material 10 for flat harness is bent following the opening / closing operation of the slide door 30, the surfaces of the first and second folding portions 14 and 16 are bent by the internal flat harness. Since it will be in the state pressed by 20 side, it will also prevent that the 1st, 2nd folding parts 14 and 16 open and the flat harness 20 will be exposed or will fall out.

  Furthermore, by making the flat harness protective material 10 into a folded structure as described above, the flat harness 20 can be thinned along the exterior flat harness 20, and the periphery of the flat harness 20 can be protected with a minimum size. Therefore, even in a narrow routing space, it is possible to easily route without interfering with the vehicle body.

  Further, as described above, by forming the flat harness protective material 10 from the flexible olefin-based elastomer strip 11, the flat harness 20 covered with the flat harness protective material 10 is connected to the slide door 30. Even when it is bridged between the vehicle body 31, the bending / extending operation can be smoothly repeated following the opening / closing operation of the slide door 30.

  Furthermore, as described above, the first and second hinge portions 12 and 13 in the protective material 10 for the flat harness are made of a flexible resin having a lower hardness than the first and second folding portions 14 and 16 and the central placement portion 15. By molding, the flat harness protective material 10 can be bent more easily, and the followability to the slide door 30 can be further improved. Further, by making the first and second hinge portions 12 and 13 more flexible, the first and second folding portions 14 and 16 can be easily folded, and the exterior workability to the flat harness 20 is further improved. Can be improved.

  Further, as described above, the flat harness protective material 10 is bent by making the cross section orthogonal to the length direction curved in the entire length of the first hinge portion 12 and the second hinge portion 13 in the length direction. You can increase the flexibility of the time.

  Further, as described above, a cylindrical shape formed of a resin harder than the protective material 10 for the flat harness in the fixed end side region A with the vehicle body side support member 33 that needs to regulate the bending angle of the flat harness 20. By covering the boot 17 with the protective material 10 for the flat harness, the bending angle of the flat harness 20 can be appropriately regulated while causing the flat harness 20 to smoothly follow the opening / closing operation of the sliding door 30, and in particular, the sliding door. It is possible to effectively prevent the flat harness 20 from interfering with the vehicle body 31 when fully opened.

  Further, as described above, by providing the slit 17a in the length direction of the cylindrical boot 17, the degree of restriction of the bending angle can be adjusted as appropriate. In other words, in the region near the fixed end with respect to the vehicle body side support member 33 that needs to sufficiently restrict the bending angle, the interval of the slit 17a provided in the length direction is widened, while the bending angle is regulated as the distance from the fixed end increases. In a region where it is possible to relax, flexibility can be gradually increased by narrowing the interval between the slits 17a provided in the length direction.

  In the second embodiment, as shown in FIG. 7, the first and second hinge portions 12 and 13 have a curved vertical cross section that is not thin, and the number of flat harnesses that are placed on the central placement portion 15 is the number of stacked flat harnesses. It is the same as that of 1st Embodiment except the point made into 4 sheets.

  Even if the number of laminated flat harnesses is increased as in the second embodiment, the same effect as in the first embodiment can be obtained.

  In the third embodiment, as shown in FIG. 8, the third embodiment is the same as the second embodiment except that the cross section perpendicular to the length direction of the first and second hinge portions 12 and 13 is inclined.

  In the third embodiment, the flexibility at the time of bending of the protective material 10 for the flat harness is slightly inferior to that of the second embodiment, but the other effects are the same as those of the second embodiment. By making the 1st, 2nd hinge parts 12 and 13 into an inclined vertical cross section, the length of the width direction of the protective material 10 for flat harnesses can be restrained shorter than 2nd Embodiment.

  In the fourth embodiment, as shown in FIG. 9, the first and second hinge portions 12 and 13 are inclined except for the cross section orthogonal to the length direction, and the inner surfaces are corrugated. The same as the third embodiment.

  Also in the fourth embodiment, the same effect as that of the third embodiment is obtained, and further, the deviation generated between the inner peripheral surface and the outer peripheral surface at the time of bending of the flat harness 20 sheathed with the protective material 10 for flat harness is bent. Absorption is facilitated, and a smoother bending operation is possible.

  In the fifth embodiment, as shown in FIG. 10, the lengths in the width direction of the first and second folding portions 14 and 16 and the center placement portion 15 are made substantially the same, and the first and second folding portions 14 are also made. 16 and the central mounting portion 15 in the entire length in the length direction, a cross section perpendicular to the length direction is formed in a curved shape, and the flat harness 20 is mounted on the central mounting portion 15 to thereby form the first and second portions. In the state where the folding parts 14 and 16 are folded, it is the same as that of the fourth embodiment except that one surface side is a concave surface and the other surface side is a convex surface. In addition, as the curvature radius of the curved shape of the vertical cross section of the 1st, 2nd folding parts 14 and 16 and the center mounting part 15, the flat harness 20 sheathed with the protective material 10 for flat harnesses is the sliding door 30 and the vehicle body 31. It is about twice the radius of curvature of the bent part when it is bent and routed.

  In the fifth embodiment, not only the same effects as in the fourth embodiment can be obtained, but also the flat harness 20 covered with the flat harness protective material 10 can be bent at a certain bending angle when the flat harness 20 is bent. A smoother bending operation following the movement of 30 is possible.

  In the sixth embodiment, in place of the cylindrical boot 17, the guide plate 18 provided with a thin portion 18 a in the length direction is bonded to the outer surface of the central mounting portion 15 as shown in FIG. This is the same as in the first embodiment. The material of the guide plate 18 is the same as that of the cylindrical boot 17, and the installation position of the thin portion 18 a is the same as the slit 17 a of the cylindrical boot 17, and the thin portion 18 a as the distance from the fixed end to the vehicle body side support member 33 increases. The interval between them is narrowed.

  Also in the sixth embodiment, as in the first embodiment, the bending angle of the flat harness 20 can be appropriately regulated while causing the flat harness 20 to smoothly follow the opening / closing operation of the sliding door 30, and in particular, the sliding door 30. It is possible to effectively prevent the flat harness 20 from interfering with the vehicle body 31 when fully opened.
