In view of the above-mentioned problems, it is an object of the present invention to provide a harness wiring structure and a connection holding member that can easily correspond to a desired wire harness wiring route.

In the present invention, the wire harness is formed into a cylindrical shape in which a convex outer circumferential convex portion along the circumferential direction and a concave outer circumferential concave portion along the circumferential direction are arranged alternately in the axial direction, and the wire harness is disposed inside the wire harness. A harness wiring structure is provided with a corrugated tube through which the corrugated tube is inserted, and a linear restriction member through which the corrugated tube is inserted and which restricts the corrugated tube in a straight line. A connecting holding member is provided inside the member over the entire length thereof, and is disposed at both ends of the straight line regulating member to straddle the boundary between the corrugated tube and the straight line regulating member, and the connecting holding member is provided with: The harness wiring structure includes a locking portion that locks with at least one of the outer circumferential recess and the outer circumferential convex portion.

Further, the present invention provides a corrugated gate which is formed into a cylindrical shape in which circumferentially extending convex outer circumferential convex portions and circumferentially concave outer circumferential concave portions are arranged alternately in the axial direction, and into which a wire harness is inserted. The linear regulating member is arranged to straddle the boundary between the corrugated tube and the end of the linear regulating member that regulates the linear shape by inserting the tube from one end to the other end, and engages with at least one of the outer circumferential recess and the outer circumferential convex portion. It is a connection holding member having a locking part.

The material of the straight line regulating member is not particularly limited as long as it is a straight tubular body into which a corrugated tube can be inserted, and includes, for example, resin and metal. Further, the straight line regulating member includes not only one piece formed of a tubular body, but also one made of a plurality of parts combined to form a tubular body.

The connection holding member may be configured to allow the corrugated tube to be inserted therein, and for example, may be formed in a U-shape when viewed from the axial direction of the corrugated tube, or may be formed in an annular cylindrical shape. Including cases where it is formed. In addition, the said connection holding member is not only the case where it is a separate body from the said straight line regulating member, but may be comprised integrally.

According to this invention, at both ends of the linear regulating member into which the corrugated tube is inserted, the locking portion of the connection holding member is connected to the outer circumferential concave portion and the outer circumferential convex portion of the corrugated tube so as to straddle the corrugated tube and the linear regulating member. By locking at least one of the parts, the straight line regulating member can be held between the connecting and holding members that are locked and fixed to the corrugated tube. Thereby, movement of the linear regulating member in the axial direction can be easily restricted by the connecting and holding member.

In this way, a corrugated tube having a predetermined length in the axial direction according to the wiring route of the wire harness is inserted through the straight line regulating member corresponding to the length of the straight part of the wiring route, and the straight line regulating member is By arranging the linear regulating member at a desired position on the corrugated tube and locking and fixing the connection holding member to both ends of the linear regulating member, the linear regulating member can be easily arranged and fixed at a desired position on the wiring path of the wire harness. Therefore, it is possible to provide a harness routing structure that can protect the curved portion of the wiring route with the corrugated tube and protect the desired location while regulating the straight line with the straight line regulating member, corresponding to the wiring route of the wire harness. .

In addition, if the position of the linear regulating member that is locked and fixed to the corrugated tube via the connection holding member is out of the desired position on the wiring route, the connection holding member and the corrugated tube are released. However, it is only necessary to move the linear regulating member along the axial direction and lock and fix the corrugated tube and the connection holding member again, and the linear regulating member can be easily adjusted to a desired position on the wiring route.

As an aspect of the present invention, the connection holding member may be formed in a cylindrical shape surrounding the outer periphery of the corrugated tube.
According to this invention, since the connection holding member can surround the outer periphery of the corrugated tube, it is possible to prevent the connection holding member from falling off from the corrugated tube. Thereby, the connection holding members can be more reliably arranged at both ends of the linear regulating member, and the movement of the linear regulating member relative to the corrugated tube can be reliably regulated within a predetermined range.

Further, as an aspect of the present invention, at least one of the connecting and holding members includes a base portion having an opening into which the corrugated tube can be inserted, and a cover portion that covers the opening, and the cover portion is arranged with respect to the base portion. A pivoting portion may be provided to pivotally connect the two.

According to the present invention, since the corrugated tube can be inserted into the base portion through the opening, the connection holding member can be easily retrofitted to the corrugated tube, and the locking portion can be reliably engaged with at least one of the outer circumferential recess and the outer circumferential convex portion. Can be stopped. Further, by pivoting the cover portion relative to the base portion and closing the opening, it is possible to prevent the connection and holding member from falling off from the corrugated tube.

Furthermore, by simply separating the cover part from the base part using the pivoting part as a pivot axis, the opening can be easily opened, and the locking of the connection holding member to the corrugated tube can be easily released. Therefore, even after the connection and holding member is assembled to the boundary between the corrugated tube and the linear regulating member, the position of the linear regulating member relative to the corrugated tube can be easily adjusted.

Further, as an aspect of the present invention, the connection holding member may include a regulating member holding portion that holds the linear regulating member.
The regulating member holding portion may hold the linear regulating member by contacting the entire circumference of the outer peripheral surface of the linear regulating member, or may partially contact the linear regulating member in the axial and circumferential directions. , including the case where the straight line regulating member is clamped.

According to this invention, the connection holding member can be locked and fixed to the corrugated tube and can also hold the linear regulating member, so that relative movement of the linear regulating member with respect to the corrugated tube can be more reliably prevented. In this way, since the position of the connection holding member can be controlled with respect to both the corrugated tube and the linear regulating member, it is possible to prevent the linear regulation member from moving along the axial direction and colliding with the connection holding member. Therefore, it is possible to prevent abnormal noise from occurring between the connection holding member and the straight line regulating member.
Furthermore, by holding the linear regulating member with the coupling and holding member, rotation of the coupling and holding member with respect to the linear regulating member can be prevented.

Furthermore, since the regulating member holding portion holds the linear regulating member by coming into contact with the outer circumferential surface of the linear regulating member, it is possible to prevent foreign matter from entering between the connection holding member and the linear regulating member. Thereby, it is possible to suppress damage to the corrugated tube inserted through the straight line regulating member and the wire harness inserted through the inside of the corrugated tube.

Moreover, as an aspect of the present invention, the connection holding member may include a corrugated tube holding part that holds the corrugated tube by contacting at least one of the outer circumferential convex part and the outer circumferential recessed part.
Holding the corrugated tube by coming into contact with at least one of the outer circumferential convex portion or the outer circumferential concave portion mentioned above refers to the case where the corrugated tube is held by a locking portion that holds the corrugated tube by engaging with the outer circumferential concave portion. , including a case where the corrugated tube is held on the inner circumferential surface of a connecting holding member that holds the corrugated tube by contacting the outer circumferential convex portion.

According to this invention, since a step is formed between the corrugated tube holding section and the regulating member holding section, the linear regulating member is arranged so as to abut the step at the boundary between the corrugated tube holding section and the regulating member holding section. can. Thereby, the straight line regulating member can be held by the connection holding member more reliably.

Moreover, as an aspect of the present invention, a plurality of the locking portions may be provided in the axial direction, and may be formed in a portion of the circumferential direction.
According to this invention, a plurality of locking portions provided in the axial direction are locked to at least one of the outer circumferential recess and the outer circumferential convex portion, so that the connection holding member can be reliably locked and fixed to the corrugated tube. Therefore, it is possible to prevent the connection holding member and the corrugated tube from unintentionally being unlocked and the connection holding member falling off from the corrugated tube. Further, by forming the locking portion in a portion in the circumferential direction, the material cost can be saved compared to the case where the locking portion is provided in the entire circumferential direction.

Moreover, as an aspect of the present invention, the locking portions adjacent in the axial direction may be provided at different positions in the circumferential direction.
The above-mentioned positions that are different from each other in the circumferential direction include not only the case where the locking portions adjacent in the axial direction do not overlap with each other in the circumferential direction, but also the case where they partially overlap in the circumferential direction.

According to this invention, since the locking portion can lock the corrugated tube from different directions in the circumferential direction, the connecting and holding member can be stably locked and fixed to the corrugated tube. Therefore, compared to the case where the corrugated tube is provided all around in the circumferential direction, material costs can be saved, and the connecting and holding member can stably hold the corrugated tube.

Further, as an aspect of the present invention, the connecting and holding member may be provided with a fixing portion that is fixed to a fixing location on the fixed member.
The fixing portion includes, for example, an anchor that is inserted into an insertion hole provided in a vehicle body panel and fixed therein, a bolt hole that is inserted and fixed with a stud bolt provided on the vehicle, and the like.

According to this invention, the connection holding member can be fixed at a predetermined location in the vehicle. Therefore, the wire harness can be routed along a desired route. Note that by moving the position of the connection holding member with respect to the corrugated tube along the axial direction, it is also possible to absorb tolerances between the fixing location and the connection holding member.

According to the present invention, it is possible to provide a harness wiring structure and a connection holding member that can easily correspond to a desired wire harness wiring route.

The end portions on the right side Ya of the inner circumferential surface of the pipe-side main body portion 811 formed in this manner are spaced apart from each other by an interval shorter than the inner diameter of the pipe-side main body portion 811. In other words, on the inner circumferential surface of the right side Ya end of the pipe side main body part 811, a pair of pipe stopper parts 814 arranged at an interval shorter than the outer diameter of the straight pipe 30 are provided in the vertical direction Z. They are provided in pairs. Note that, as shown in FIG. 8B, the pipe retaining portion 814 is configured to be at the same height as the corrugated retaining portion 714 on the right side Ya of the corrugated retaining portion 714.

As shown in FIGS. 5 and 8(b), the third opening forming part 812 extends from the upper side Za of the pipe side main body part 811 toward the right side Ya, similarly to the first opening forming part 712. . The upper end surface of this third opening forming part 812 is on the left side Yb of the pipe-side main body part 811 as it goes toward the right side Ya, and from the upper end surface of the right side Ya of the pipe side main body part 811 to the upper side Za. It protrudes so as to be inclined toward the corrugated gate, and is configured to be flat on the right side Ya of the portion corresponding to the corrugated retaining portion 714. That is, the upper end surface of the upper side Za of the third opening forming part 812 is configured to be flush with the upper end surface of the first opening forming part 712 (the end surface of the upper side Za). The third opening forming portion 812 configured in this manner has a thicker plate than the pipe-side base 81 and has higher rigidity than the end portion of the pipe-side main body portion 811.

On the other hand, unlike the third opening forming part 812, the fourth opening forming part 813 extending from the lower side Zb of the pipe side main body part 811 toward the right side Ya is different from the third opening forming part 812 in that the plate thickness at the base end part is equal to that of the pipe side base. 81. The pivot portion 53 provided in the second opening forming portion 713 is provided continuously along the longitudinal direction X on the lower end surface of the fourth opening forming portion 813 (the end surface of the lower side Zb). Note that the lower end surface of the fourth opening forming part 813 is flush with the lower end surface of the second opening forming part 713.

Further, on the inside of the third opening forming portion 812 and the fourth opening forming portion 813 in the vertical direction Z, as viewed from the longitudinal direction Slanted pipe guide portions 815 are respectively formed. This pipe guide section 815 is flush with the corrugated guide section 715 (see FIG. 4(b), FIG. 5, and FIG. 8(b)).

As shown in FIGS. 4 to 8, the fixing portion 60 includes an anchor placement portion 61 provided on the opposite side of the opening S in the base 51, and an anchor 62 protruding from the anchor placement portion 61 toward the upper side Za. has been done.

The anchor arrangement section 61 includes a substantially rectangular parallelepiped arrangement main body 611 that is integrally formed with the base 51 on the opposite side of the opening S in the base 51, and an upper reinforcing section that extends from the upper side Za of the arrangement section main body 611 toward the base 51. portion 612 and a lower reinforcing portion 613 extending from the lower side Zb of the placement portion main body 611 toward the base 51.

As shown in FIGS. 4(a) and 4(b), the arrangement portion main body 611 has a substantially square columnar shape that is connected to the outer peripheral surface of the left side Yb of the base 51 at the center in the longitudinal direction X of the base 51. It is a pedestal. The length of the arrangement main body 611 along the longitudinal direction X is approximately half the length of the base 51 along the longitudinal direction It is configured to be shorter than the outer diameter of the Further, the length of the placement portion main body 611 along the vertical direction Z is approximately the same as the outer diameter of the base 51. Note that the end surface of the upper side Za of the arrangement portion main body 611 is flush with the first opening forming portion 712 and the third opening forming portion 812.

The upper reinforcing part 612 is a reinforcing member having the same width as the width in the longitudinal direction X of the arrangement part main body 611, and as shown in FIGS. It extends toward the side Ya and is in contact with the outer circumferential surface of the base 51. Further, the upper reinforcing portion 612 and the third opening forming portion 812 are connected by a reinforcing extension portion 614 formed narrowly with respect to the upper reinforcing portion 612 (see FIG. 4).

In this way, the reinforcing extension part 614 that connects the upper reinforcing part 612 and the third opening forming part 812 has its lower end connected to the outer circumferential surface of the base 51. By working together, deformation of the left side Yb of the base 51 can be suppressed.

The lower reinforcing portion 613 extending from the lower Zb end of the placement portion main body 611 toward the right side Ya is a reinforcing member having the same width as the width in the longitudinal direction X of the placement portion main body 611. As shown in FIGS. 7 and 8, the arrangement portion main body 611 and the outer circumferential surface of the base 51 are connected. This lower reinforcing portion 613 is connected to the left side Yb of the base 51, and can suppress deformation of the left side Yb of the base 51 at the lower side Zb.

In this way, the upper reinforcing part 612 and the reinforcing extension part 614 extend along the width direction Y from the arrangement part main body 611 to the first opening forming part 712 and the third opening forming part 812, whereas the lower reinforcing part 613 does not extend from the placement portion main body 611 to the second opening forming portion 713 and the fourth opening forming portion 813, and is connected to the base 51 at a position corresponding to the center portion of the base 51 in the width direction Y. Further, as described above, since the first opening forming part 712 and the third opening forming part 812 are thicker than the second opening forming part 713 and the fourth opening forming part 813, the corrugate 20 and the straight pipe 30 into the base 51, the second opening forming part 713 and the fourth opening forming part 813 are bent toward the lower side Zb compared to the first opening forming part 712 and the third opening forming part 812. Become.

As shown in FIGS. 4 to 8, the anchor 62 includes a fixed shaft portion 621 extending from the anchor arrangement portion 61 toward the upper side Za, and a pair of fixed shaft portions 621 extending along the longitudinal direction X from the tip of the fixed shaft portion 621. It consists of a locking arm 622. Note that an umbrella-shaped panel contact portion 623 is provided at the upper end portion of the locking arm 622.
As shown in FIG. 6(a), the locking arm 622 has a distal end connected to the distal end of the fixed shaft portion 621, and gradually extends from the fixed shaft portion 621 from the distal end side to the proximal end side of the fixed shaft portion 621. They are spaced apart.

The panel contact portion 623 is formed into a substantially oval shape when viewed from the vertical direction Z, and comes into contact with the surface of the body panel P when the anchor 62 is inserted into the anchor hole P1 of the body panel P. Further, since the panel contact portion 623 is inclined toward the upper side Za as it is separated from the fixed shaft portion 621, the connecting holder 40 can be stably supported with respect to the body panel P by its elastic force (see FIG. 12). ).

The connecting holder 40 configured as described above can be attached to both ends of the straight pipe 30 with the corrugated wire 20 through which the wire harness 10 is inserted, inserted over the entire length of the straight pipe 30. Relative movement of the straight pipe 30 with respect to the corrugated gate 20 can be restricted. Hereinafter, details will be given regarding the attachment method for attaching the connecting holders 40 to both ends of the straight pipe 30 through which the corrugated gate 20 is inserted, and the harness wiring structure 1 in which the connecting holders 40 are assembled to both ends of the straight pipe 30 through which the corrugated gate 20 is inserted. Describe.

First, the wire harness 10 is inserted through the corrugated gate 20. Then, insert the corrugated pipe 20 over the entire length of the straight pipe 30, adjust the position of the straight pipe 30 with respect to the corrugated pipe 20 at a location where you want to regulate the straight line in the wiring route of the wire harness 10, and insert the straight pipe 30 into the straight pipe 30. A connecting holder 40 is attached so as to straddle the corrugate 20 and the straight pipe 30 at both end portions.

Specifically, at both ends of the straight pipe 30, with the cover 52 open to the base 51, each connecting holder 40 is arranged so that the anchor 62 faces in a predetermined direction (upper side Za), The straight pipe 30 is inserted into the pipe side main body part 811 through the opening S formed between the third opening forming part 812 and the fourth opening forming part 813, and the first opening forming part 712 and the second opening forming part The corrugate 20 is inserted into the corrugate side main body part 711 through the opening S formed between the corrugate body part 713 and the corrugate body part 711 .

At this time, by placing the straight pipe 30 along the pipe guide portion 815, the straight pipe 30 can be easily guided to the pipe side main body portion 811, and the straight pipe 30 can be easily guided to the pipe side main body portion 811. Can be inserted. Moreover, although the opening S of the pipe-side main body part 811 is narrower than the outer diameter of the straight pipe 30 due to the pair of pipe stopper parts 814, the opening S of the pipe-side main body part 811 is narrower than the outer diameter of the straight pipe 30. Since the opening forming portion 813 deforms toward the lower side Zb so as to widen the opening S, the straight pipe 30 can be inserted into the pipe side main body portion 811.

The straight pipe 30 inserted into the pipe-side main body part 811 in this manner can be held by the pipe-side main body part 811 having an inner circumferential surface with an inner diameter equal to the outer diameter of the straight pipe 30. In addition, since the fourth opening forming part 813 returns to its original position after inserting the straight pipe 30 into the pipe side main body part 811, the pair of pipe stopper parts 814 allow the straight pipe 30 to pass through the opening S. It is possible to prevent it from falling off from the portion 811. Therefore, the straight pipe 30 can be temporarily fixed to the pipe-side main body part 811.

In addition, by bringing the end of the straight pipe 30 into contact with the step D formed between the corrugated holding part 70 and the pipe holding part 80 in the pipe side main body part 811, the straight pipe in the pipe side main part 811 The straight pipe 30 can be placed at a position where the pipe 30 can be held securely. Therefore, the straight pipe 30 can be reliably held by the connecting holder 40.

Similarly, from the opening S formed between the first opening forming part 712 and the second opening forming part 713, along the longitudinal direction The corrugate 20 is inserted into the corrugate side main body part 711 so that the outer peripheral recesses 22 are arranged in parallel. At this time, by placing the corrugate 20 along the corrugate guide portion 715, the corrugate 20 can be easily guided to the corrugate side main body portion 711, so that the corrugate 20 can be easily inserted into the corrugate side main body portion 711.

Furthermore, although the opening S of the corrugated main body part 711 is narrower than the outer diameter of the outer circumferential convex part 21 due to the pair of corrugated retaining parts 714, by pushing the straight pipe 30 into the pipe side main part 811, the fourth Since the second opening forming part 713 configured integrally with the opening forming part 813 also deforms toward the lower side Zb, the corrugate 20 can be reliably and easily inserted into the corrugate side main body part 711. In addition, by pushing the corrugate 20 into the corrugate side main body part 711, the corrugate 20 is deformed toward the lower side Zb so that the diameter of the corrugate 20 is reduced or the second opening forming part 713 widens the opening S, so that the corrugate removal prevention part Even when the distance between the corrugated corrugated holes 714 is narrower than the outer diameter of the outer circumferential convex portion 21, the corrugated corrugated portion 20 can be inserted into the corrugated corrugated body portion 711.

In this way, in the corrugate 20 inserted into the corrugate side main body part 711, the outer peripheral recess 22 of the corrugate 20 exposed from the end of the straight pipe 30 fits into the first locking part 73. Furthermore, the outer circumferential recess 22 that is two spaces apart in the longitudinal direction X from the outer circumferential recess 22 that is fitted into the first locking part 73 fits into the second locking part 74 . Thereby, the connection holder 40 is locked to the corrugated gate 20 (see FIG. 11).

In addition, since the second opening forming part 713 returns to its original position after inserting the corrugate 20 into the corrugate side main body part 711, the pair of corrugate slip-off prevention parts 714 prevent the corrugate 20 from falling out from the corrugate side main body part 711 via the opening S. This can be prevented. Therefore, the corrugate 20 can be temporarily fixed to the corrugate side main body part 711.

Then, with the corrugated gate 20 and the straight pipe 30 inserted into the base 51, the cover 52 is pivoted via the pivot portion 53, and the locking piece 55 and the insertion portion 54 are locked. As a result, the third locking part 75 and the fourth locking part 76 provided on the inner peripheral surface of the corrugated side cover 72 are inserted so as to fit into the outer peripheral recess 22, and the inner peripheral surface of the corrugated side cover 72 The outer peripheral convex portion 21 can be held between the surface and the inner peripheral surface of the corrugated main body portion 711. Further, the straight pipe 30 can be held between the inner circumferential surface of the pipe-side cover 82 and the inner circumferential surface of the pipe-side main body portion 811.

In this way, by closing the opening S of the base 51 with the cover 52, the outer periphery of the corrugated gate 20 and the straight pipe 30 is surrounded by the cylindrical connecting holder 40 (FIGS. 1 and 2). reference). Thereby, the corrugates 20 and 30 can be prevented from slipping out from the connection holder 40.

At both ends of the straight pipe 30 through which the corrugate 20 is inserted, the connection holder 40 fixed to the boundary between the corrugate 20 and the straight pipe 30 is connected to the corrugate 20 as shown in FIGS. 10 and 11. The straight pipe 30 can be held and fixed to the straight pipe 30 .

As a result, the two connecting holders 40 latched and fixed to the corrugate 20 can sandwich the straight pipe 30 (see FIG. 10), and the straight pipe 30 moves relative to the corrugate 20 in the longitudinal direction X. This can definitely be prevented. Therefore, unintended displacement of the straight pipe 30 with respect to the corrugated gate 20 can be prevented, and the straight pipe 30 can be reliably fastened at a location where straightness is desired to be restricted in the wiring route of the wire harness 10.

In addition, as shown in FIG. 11, the connecting holder 40 attached to both ends of the straight pipe 30 grips the straight pipe 30 with a pipe-side main body part 811 and a pipe-side cover 82, and also holds the straight pipe 30 at the first locking position. Since the corrugate 20 is locked and fixed by the portion 73 , the second locking portion 74 , the third locking portion 75 , and the fourth locking portion 76 , the position of the straight pipe 30 with respect to the corrugate 20 is restricted. This can prevent the straight pipe 30 from moving along the axial direction (longitudinal direction This can be prevented.

In this way, it is possible to prepare the harness wiring structure 1 in which the relative position of the straight pipe 30 with respect to the corrugate 20 is regulated at a desired position in the corrugate 20 through which the wire harness 10 is inserted via the connection holder 40. Then, the anchor 62 in the harness wiring structure 1 is inserted into the anchor hole P1 of the body panel P (see FIG. 12).

As a result, the pair of locking arms 622 can be locked to the edge of the anchor hole P1, and the panel contact portion 623 is brought into contact with the surface of the body panel P. By sandwiching P, the harness wiring structure 1 can be stably fixed to the body panel P.

In this way, the harness wiring structure 1 has a cylindrical shape in which the wire harness 10, the circumferentially protruding outer circumferential protrusions 21, and the circumferentially concave outer circumferential recesses 22 are alternately arranged in the longitudinal direction X. It is provided with a corrugate 20 which is formed into a shape and into which the wire harness 10 is inserted, and a straight pipe 30 through which the corrugate 20 is inserted and which regulates the corrugate 20 in a straight line. A portion of the corrugate 20 is disposed inside the straight pipe 30 over the entire length thereof, and a connecting holder is disposed at both ends of the straight pipe 30 to straddle the boundary between the corrugate 20 and the straight pipe 30. 40, and the connecting holder 40 has a first locking portion 73, a second locking portion 74, a third locking portion 75, and a fourth locking portion 76 that lock with the outer peripheral recess 22.

The connection holder 40 is formed into a cylindrical shape in which circumferentially protruding outer circumferential convex portions 21 and circumferentially concave outer circumferential concave portions 22 are alternately arranged in the longitudinal direction The corrugate 20 is inserted from one end to the other end of the straight pipe 30 and the boundary between the corrugate 20 and the end of the straight pipe 30 is inserted, and the corrugate 20 is inserted into the corrugate 20 from one end to the other. It has a first locking part 73, a second locking part 74, a third locking part 75, and a fourth locking part 76 that lock with at least one of them.

The harness wiring structure 1 configured in this manner has the first locking of the connecting holder 40 so as to straddle the corrugate 20 and the straight pipe 30 at both ends of the straight pipe 30 into which the corrugate 20 is inserted. portion 73 , second locking portion 74 , third locking portion 75 , and fourth locking portion 76 are locked in outer circumferential recess 22 of corrugate 20 . Therefore, the straight pipe 30 can be held between the connecting holders 40 that are locked and fixed to the corrugated gate 20, and the movement of the straight pipe 30 in the longitudinal direction X can be easily restricted by the connecting holders 40.

In this way, the corrugated gate 20 having a predetermined length in the longitudinal direction By arranging the pipe 30 at a desired position in the corrugated gate 20 and locking and fixing the connecting holders 40 to both ends of the straight pipe 30, the straight pipe 30 can be easily moved to a desired position on the wiring route of the wire harness 10. It can be placed in Therefore, in the corrugated pipe 20 and the straight pipe 30 through which the wire harness 10 is inserted, the straight pipe 30 can be easily arranged at a location where straight lines are restricted. 10 can be curved. That is, the harness wiring structure 1 can be easily made to correspond to the wiring route of the wire harness 10.

Furthermore, if the position of the straight pipe 30 that is locked and fixed to the corrugated gate 20 via the connecting holder 40 is out of the desired position on the wiring route, the connecting holder 40 and the corrugated gate 20 are not locked together. If the straight pipe 30 is released, the straight pipe 30 is moved along the longitudinal direction X, and the corrugated gate 20 and the connecting holder 40 are locked and fixed again, the straight pipe 30 can be easily adjusted to a desired position on the wiring route. can.

Moreover, since the connecting holder 40 (holding part 50) is formed in a cylindrical shape that surrounds the outer periphery of the corrugated gate 20, the connecting holder 40 (holding part 50) can surround the outer periphery of the corrugated gate 20, so that it can be removed from the corrugated gate 20. It is possible to prevent the connecting holder 40 from falling off. Thereby, the connection holders 40 can be arranged at both ends of the straight pipe 30 more reliably, and the movement of the straight pipe 30 with respect to the corrugated pipe 20 can be reliably restricted within a predetermined range.

Furthermore, the connecting holder 40 (holding part 50) provided at both ends of the straight pipe 30 is composed of a base 51 having an opening S into which the corrugated gate 20 can be inserted, and a cover 52 covering the opening S. A pivot portion 53 is provided to pivotally connect the cover 52 to the pivot portion 53 .

As a result, the corrugate 20 can be inserted into the base 51 (corrugate side base 71) through the opening S, so the connection holder 40 can be easily retrofitted to the corrugate 20, and the first locking portion 73 and the second locking portion can be reliably connected. The third locking portion 74 , the third locking portion 75 , and the fourth locking portion 76 can be locked to at least one of the outer circumferential recess 22 and the outer circumferential convex portion 21 . Moreover, by pivoting the cover 52 with respect to the base 51 and closing the opening S, the connection holder 40 can be prevented from falling off from the corrugated gate 20.

Further, by simply separating the cover 52 from the base 51 using the pivoting portion 53 as a pivot axis, the opening S can be easily opened, and the locking of the connecting holder 40 to the corrugated gate 20 can be easily released. Therefore, even after the connection holder 40 is assembled to the boundary between the corrugated pipe 20 and the straight pipe 30, the position of the straight pipe 30 with respect to the corrugated pipe 20 can be easily adjusted.

Furthermore, since the connecting holder 40 (holding section 50) is provided with the pipe holding section 80 that holds the straight pipe 30, the holding section 50 (corrugate holding section 70) can be locked and fixed to the corrugated gate 20, and can also be held straight. Since the pipe 30 can be held, relative movement of the straight pipe 30 with respect to the corrugated gate 20 can be more reliably prevented. Therefore, unintentional displacement of the straight pipe 30 with respect to the corrugated gate 20 can be prevented, and the straight pipe 30 can be reliably held at a desired position on the wiring route.

Moreover, since the position of the connecting holder 40 (holding part 50) can be controlled with respect to both the corrugated gate 20 and the straight pipe 30, the straight pipe 30 moves along the longitudinal direction X and the connecting holder 40 (holding part 50) This can prevent collisions with Therefore, it is possible to prevent abnormal noise from occurring between the connecting holder 40 (holding part 50) and the straight pipe 30.
Furthermore, by holding the straight pipe 30 with the connecting holder 40, rotation of the connecting holder 40 with respect to the straight pipe 30 can be prevented.

In addition, since the pipe holding portion 80 holds the straight pipe 30 by contacting the outer circumferential surface of the straight pipe 30, foreign matter is prevented from entering between the connection holder 40 and the straight pipe 30. can. Thereby, damage to the corrugate 20 inserted into the straight pipe 30 and the wire harness 10 inserted into the corrugate 20 can be suppressed.

Furthermore, the connection holder 40 (holding part 50) has a first locking part 73 and a third locking part 75 that come into contact with the outer circumferential recess 22 and hold the corrugate 20. As a result, a step D is formed between the pipe holding part 80 and the first locking part 73 and third locking part 75 provided at the end of the corrugated holding part 70, so that the corrugated holding part 70 and the pipe holding part 70 are connected to each other. The straight pipe 30 can be arranged so as to abut the step D at the boundary with the section 80. Therefore, the straight pipe 30 can be held in the connecting holder 40 more reliably.

Moreover, the first locking part 73, the second locking part 74, the third locking part 75, and the fourth locking part 76 are provided in plurality in the longitudinal direction X, and are formed in a part of the circumferential direction. As a result, the first locking portion 73, the second locking portion 74, the third locking portion 75, and the fourth locking portion 76, which are provided in plurality in the longitudinal direction X, are locked in the outer circumferential recess 22. , the connecting holder 40 can be reliably locked and fixed to the corrugated gate 20. Therefore, it is possible to prevent the connection holder 40 and the corrugated gate 20 from unintentionally being unlocked and the connection holder 40 falling off from the corrugated gate 20. In addition, by forming the first locking part 73, the second locking part 74, the third locking part 75, and the fourth locking part 76 in a part of the circumferential direction, compared to the case where they are provided all around the circumferential direction, You can also save on material costs.

Furthermore, the first locking part 73, the second locking part 74, the third locking part 75, and the fourth locking part 76 that are adjacent to each other in the longitudinal direction X are provided at mutually different positions in the circumferential direction. As a result, the first locking portion 73, the second locking portion 74, the third locking portion 75, and the fourth locking portion 76 can lock the corrugate 20 from different directions in the circumferential direction. The connection holder 40 can be stably locked and fixed. Therefore, the material cost can be saved compared to the case where it is provided all around the circumference, and the connecting holder 40 can stably hold the corrugate 20.

Furthermore, since the connecting holder 40 is provided with an anchor 62 that is fixed to the anchor hole P1 in the body panel P, the connecting holder 40 can be fixed to the anchor hole P1 in the vehicle. Therefore, the wire harness 10 can be routed along a desired route. In addition, by moving the position of the connection holder 40 with respect to the corrugated gate 20 along the longitudinal direction X, the tolerance between the anchor hole P1 and the connection holder 40 can also be absorbed.

Although the fixing portion corresponds to the anchor 62, the present invention is not limited to only the configuration of the above-described embodiments, and many embodiments can be obtained.

For example, in the present embodiment, the first locking portion 73, the second locking portion 74, the third locking portion 75, and the fourth locking portion 76 provided on the corrugated side main body portion 711 and the corrugated side cover 72 are as follows: Although the corrugate 20 and the connection holder 40 are locked by fitting into the outer circumferential recess 22, the structure is not limited to this. For example, the corrugated main body part 711 has an inner circumferential surface with an inner diameter approximately equal to the outer diameter of the outer circumferential recess 22, and instead of ribs protruding from the inner circumferential surfaces of the corrugated main body part 711 and the corrugated cover 72, an outer circumferential convex A recess into which the section 21 fits may be provided on the inner circumferential surface of the corrugated main body 711 and the corrugated cover 72, or the above-mentioned recess or inner surface may be provided on the inner circumferential surface of the corrugated main body 711 and the corrugated cover 72. Both ribs protruding from the circumferential surface may be provided.

Further, in this embodiment, a first locking portion 73 and a third locking portion 75 are provided at the boundary between the corrugated holding portion 70 and the pipe holding portion 80. That is, the first locking portion 73 and the third locking portion 75 are provided at the end of the corrugated holding portion 70 on the pipe holding portion 80 side. However, the first locking part 73 and the third locking part 75 may be provided closer to the corrugate holding part 70 than the end of the corrugated holding part 70 on the pipe holding part 80 side. In this case, the inner diameter of the inner circumferential surface of the corrugated body section 711 is attached to the pipe holding section 80 side of the first locking section 73 and the third locking section 75 so as to hold the outer circumferential surface of the outer circumferential convex section 21. By making the outer diameter equal to the outer diameter of the outer peripheral convex portion 21, a step D can be formed at the boundary between the corrugated holding portion 70 and the pipe holding portion 80.

Further, at the boundary between the corrugated pipe 20 and the straight pipe 30, the outer circumferential surface of the straight pipe 30 and the outer circumferential surface of the corrugated pipe 20 may be wrapped with a tape member so as to straddle the boundary. In this case, the movement of the straight pipe 30 in the axial direction with respect to the corrugate 20 can be more reliably restricted, and the water-tightness between the corrugate 20 and the straight pipe 30 can be improved.

Further, in this embodiment, the straight pipe 30 having a cylindrical shape is illustrated as an example of the straight line regulating member, but it may be a tubular body other than a cylindrical shape.
