Description
Technical Field
The present invention relates to a grommet for closing a wire through hole through which a power supply wire of a vehicle body panel passes, and a wire harness having the grommet.
Background
Conventionally, various grommet have been proposed (see JP 2016-. As such a grommet, there is a conventional grommet as shown in fig. 13 to 16B. In fig. 13 to 16B, the electric wire through-hole 2 is formed in the vehicle body panel 1. The wire W passes through the wire through hole 2. The conventional grommet 100 is attached to the outer periphery of the electric wire W. The conventional grommet 100 includes: a grommet body 101, the grommet body 101 being formed of a flexible material (such as a rubber material); and an inner protector 110, the inner protector 110 being disposed inside the grommet body 101, and being formed of a material having higher rigidity than that of the grommet body 101.
The lip 102 is formed on the abutment surface side of the grommet main body 101 with the vehicle body panel 1. The inner protector 110 is provided with a plurality of panel locking claws 111 at intervals in the circumferential direction. The grommet 100 is attached to the vehicle body panel 1 by sandwiching the outer peripheral edge of the wire through hole 2 of the vehicle body panel 1 with the panel locking claw 111 and the lip 102. The clamping force of the panel locking claw 111 and the lip 102 on the vehicle body panel 1 brings the lip 102 into close contact with the outer peripheral edge of the wire passing hole 2 of the vehicle body panel 1.
The wire holding cylindrical portion 103 is formed on the side of the grommet main body 101 opposite to the contact surface of the vehicle body panel 1. The tape T is wound around the wire holding cylindrical portion 103 and the portion of the electric wire W led out from the wire holding cylindrical portion 103 to the outside. The inner surface of the wire holding cylindrical portion 103 is in close contact with the outer periphery of the wire W.
Thus, for example, the grommet 100 attached from one side of the vehicle body panel 1 makes the wire through-hole 2 for routing the electric wire W through the space 3 of one side and the space 4 of the other side of the vehicle body panel 1 waterproof.
As shown in fig. 16A, the electric wires W drawn out from the electric wire through-holes 2 to the other side of the vehicle body panel 1 need to be routed in a desired wiring path, in other words, in a wiring path capable of avoiding interference with the peripheral component 140 and ensuring a necessary gap G with the peripheral component 140. Therefore, in the conventional grommet 100, winding the tape T on the electric wire W and mounting the clip 120 on the tape T to fix the clip 120 to the vehicle body (not shown) causes the path of the electric wire W to be forcibly restricted to a desired path.
Disclosure of Invention
However, in the conventional grommet 100, in order to obtain a wiring path capable of avoiding interference of the electric wire W with the peripheral member 140 and securing a necessary gap G with the peripheral member 140, the clip 120 as a vehicle body fixing member is required, and an operation for fixing the clip 120 to the vehicle body is extremely difficult and troublesome.
Specifically, as shown in fig. 16A, when it is necessary to shorten the length L from the vehicle body panel 1 to the clip 120 in order to secure the interval G between the peripheral member 140 and the electric wire W, since a large tension from the electric wire W acts on the clip 120, the winding fixing position of the tape T may be shifted by aging, and the predetermined gap G may not be secured.
The present application has been made to solve the above problems, and an object of the present application is to provide a grommet capable of routing electric wires to a desired path without requiring a vehicle body fixing part and performing difficult and troublesome work, and a wire harness having the grommet.
A grommet for closing an electric wire through hole through which an electric wire of a vehicle body panel passes according to an aspect of the present application includes: a grommet main body for covering the electric wire at one side of the vehicle body panel and making close contact with a peripheral edge of the electric wire through-hole; an inner protector formed of a material having higher rigidity than the grommet main body and disposed inside the grommet main body; and a path regulating member fixed to the inner protector, the path regulating member regulating a path of the electric wire drawn to the other side of the body panel.
With the grommet according to the aspect of the present application, the path regulating member is attached to the grommet, and the path regulating member regulates the path of the electric wire drawn out to the other side of the vehicle body panel, so that the electric wire can be routed to a desired path. As described above, in the grommet according to the aspect of the present application, the vehicle body fixing part is not required, and furthermore, the electric wire can be routed to a desired path without performing difficult and complicated work.

Detailed Description
A grommet according to some embodiments will be described with reference to the accompanying drawings.
First embodiment
Fig. 1 to 5B illustrate a grommet 10 according to a first embodiment.
As shown in fig. 3, 5A and 5B, a circular electric wire through-hole 2 is formed in a vehicle body panel 1. The wires W of the wire harness penetrate the wire through-holes 2, thereby routing the wires through the space 3 on one side of the body panel 1 to the space 4 on the other side of the body panel 1. The wire harness includes a grommet 10 attached to the outer periphery of the electric wire W. The wire through-hole 2 of the body panel 1 is closed by a grommet 10.
Next, the configuration of the grommet 10 will be described in detail.
The grommet 10 is attached to the electric wire through hole 2 from the space 3 on the vehicle body panel 1 side. The grommet 10 includes: a grommet body 11 formed of a flexible material (e.g., a rubber material); an inner protector 20 that is disposed inside the grommet body 11 and is formed of a material having higher rigidity than the grommet body 11; and a path regulating member 30 fixed to the inner protector 20.
The grommet main body 11 has a cylindrical shape capable of routing the electric wire W inside. The grommet body 11 includes the following integrally provided: a large-diameter cylindrical portion 12 having an inner engagement groove 13 on an inner peripheral side of the large-diameter cylindrical portion 12; a lip 15, the lip 15 being provided on the vehicle body panel 1 side of the large-diameter cylindrical portion 12; and a wire holding cylindrical portion 19, the wire holding cylindrical portion 19 being provided on the opposite side of the large diameter cylindrical portion 12 from the vehicle body panel 1 side. The large-diameter cylindrical portion 12 has a larger diameter than the wire through-hole 2. The inner engagement groove 13 is formed over the entire circumference of the large-diameter cylindrical portion 12. The outer periphery of the inner protector 20 is fitted to the inner fitting groove 13. Thus, the grommet main body 11 and the inner protector 20 are fixed to each other. The grommet main body 11, particularly the large-diameter cylindrical portion 12, is maintained in shape by the inner protector 20.
The lip portion 15 protrudes from the outer peripheral edge surface of the large-diameter cylindrical portion 12 on the vehicle body panel 1 side. The lip 15 includes an inner peripheral lip 16 and an outer peripheral lip 17. The inner and outer peripheral lips 16 and 17 are continuously formed over the entire circumference of the large-diameter cylindrical portion 12.
Before the grommet 10 is attached to the wire through-hole 2, the inner peripheral lip 16 protrudes from the root portion toward the center axis direction. The tip end side of the inner peripheral lip 16 is inclined in a direction opening outward with respect to the center axis. The outer peripheral lip 17 protrudes in a direction opening outward with respect to the center axis direction. In a state where the grommet 10 is attached to the wire through hole 2, the inner peripheral lip portion 16 and the outer peripheral lip portion 17 are elastically deformed in a direction inclined to the outer peripheral surface of the large-diameter cylindrical portion 12, and brought into close contact with the peripheral surface of the wire through hole 2 of the vehicle body panel 1. Thereby, water or the like is prevented from entering the grommet 10 from the gap between the surface on the vehicle body panel 1 side and the lip 15. In fig. 2 and 3, the inner peripheral lip 16 and the outer peripheral lip 17 illustrate a state before the grommet 10 is attached to the wire through-hole 2.
The wire holding cylindrical portion 19 has an inner diameter slightly smaller than or substantially the same as the outer diameter of the wire W. The wire holding cylindrical portion 19 abuts on the outer peripheral surface of the wire W by a predetermined length, and a tape (not shown) is wound around the outer peripheral surface of the wire holding cylindrical portion 19. Thus, water or the like is prevented from entering the grommet 10 from the gap between the inner surface of the wire holding cylindrical portion 19 and the outer peripheral surface of the wire W.
The wire holding cylindrical portion 19 is formed of a flexible material (e.g., a rubber material). Thereby, the electric wire holding cylindrical portion 19 can be bent and deformed together with the electric wire W, and the electric wire W led out to the space 4 of the other side (the attaching side of the grommet 10) of the vehicle body panel 1 can be routed in a desired path within the range of bending and deformation.
The inner protector 20 is formed by a pair of inner members 21 assembled with each other. Each inner part 21 comprises: an inner body portion 22 having a semicircular shape when viewed from above; and a flange portion 28 that projects outwardly from the inner body portion 22. The inner body portion 22 includes: a semicircular sidewall 23; an upper regulating wall portion 24 provided from the semicircular side wall 23 toward the inner peripheral side; and a lower regulating wall portion 25 provided at a lower position spaced from the upper regulating wall portion 24. An engagement groove 26 having a semicircular arc shape and surrounded by the upper regulation wall portion 24 and the lower regulation wall portion 25 is formed in the inner body portion 22. In a state where the pair of inner members 21 are coupled, the two engagement grooves 26 are formed in a circumferential groove shape.
A cutout portion 27 having a triangular shape when viewed from above is formed in the upper regulating wall portion 24. In a state where the pair of inner members 21 are coupled, the two cutout portions 27 are formed in a rectangular cutout shape.
The locking portions 29 are provided near the respective joining surfaces of the respective inner members 21. In a state where the coupling surfaces of the pair of inner members 21 are in contact with each other, the pair of inner members 21 are locked to each other by the lock portions 29 of the pair of inner members 21.
The plurality of panel locking claws 29A are provided at intervals on the outer peripheral surface of the semicircular side wall 23. The distal end side of each panel locking claw 29A is elastically deformable in a direction approaching the semicircular side wall 23. The plurality of panel locking claws 29A of the inner protector 20 sandwich the vehicle body panel 1 with the lip 15 of the grommet main body 11. This clamping force attaches the grommet 10 to the electric wire through-hole 2 of the vehicle body panel 1.
The path regulating member 30 is formed of a material having rigidity capable of maintaining at least its own form when the electric wire W is accommodated inside. The path regulating member 30 is a cylindrical body for accommodating the electric wire W therein. The path regulating member 30 extends along the desired routing direction of the electric wire W. Specifically, the path regulating member 30 is bent at a portion close to the base end portion fixed to the inner protector 20, and linearly extends in an oblique direction from the bent portion to the tip end.
The path regulating member 30 includes: a path regulating body 31; a cover 33, the cover 33 being connected to the path regulating body 31 by a hinge 32; and a base flange portion 34, the base flange portion 34 being attached to the path regulating body 31 and the base end portion of the cover 33. The path regulating body 31 includes a substantially U-shaped wall surface portion extending in a desired arrangement direction of the wires W. The wire housing chamber 35 is formed in a U-shaped wall portion of the path regulating body 31. The cover 33 is provided so that the electric wire accommodation chamber 35 can be opened with the hinge portion 32. In the closed position of the path regulating member 30, the path regulating member 30 is locked by the respective locking portions 36 of the path regulating body 31 and the cover 33.
In the path regulating member 30, the base flange portion 34 is fitted into the circumferential fitting groove 26 of the inner protector 20 (the coupled pair of inner body portions 22), and the distal end side of the base flange portion 34 protrudes outward from the pair of cutout portions 27 having the quadrangular shape of the inner protector 20 (the coupled pair of upper regulating wall portions 24). The path regulating member 30 is prevented from rotating with respect to the inner protector 20 by the notch portion 27, and the path regulating member 30 is fixed in a protruding state in a predetermined direction by the engagement groove 26. In other words, the path regulating member 30 extends in the predetermined direction in the space 4 on the other side of the vehicle body panel 1, and regulates the path of the electric wire W drawn out to the space 4 on the other side of the vehicle body panel 1. As shown in fig. 5A, the path regulating member 30 lays the electric wire W in a wiring path capable of avoiding interference with the peripheral member 140 and ensuring a necessary gap G with the peripheral member 140.
In the path regulating member 30, the base flange portion 34 is fitted into the fitting groove 26 of the inner protector 20 without any clearance. The path regulating member 30 is not displaced in the horizontal direction or in the swinging direction. By extension, the wiring path of the internal electric wire W is uniquely specified.
Next, the assembling steps of the grommet 10 will be described.
First, the electric wire W is accommodated in the path regulating member 30. In other words, as shown in fig. 4A, with the cover 33 opened, the electric wire W is routed in the path regulating body 31, and then the cover 33 is closed.
Next, the path regulating member 30 is attached to the inner protector 20. That is, as shown in fig. 4B, the base flange portion 34 of the path regulating member 30 is set between the pair of inner members 21, and the pair of inner members 21 are joined while the base flange portion 34 is fitted into the fitting grooves 26 of the pair of inner members 21 (see fig. 4C).
Next, the inner protector 20 is fitted to the grommet main body 11 through which the electric wire W passes. That is, as shown in fig. 4D, the large-diameter cylindrical portion 12 of the grommet main body 11 is elastically deformed in the expanding direction, and the flange portion 28 of the inner protector 20 is fitted into the inner fitting groove 13 of the grommet main body 11. Thereby, the grommet 10 is attached to the electric wire W.
Next, the electric wire W is passed through the electric wire through hole 2 of the vehicle body panel 1, and the grommet 10 is pushed into the electric wire through hole 2 from the space 3 on the side of the vehicle body panel 1 with the path regulating member 30 as the insertion tip side. Then, the path regulating member 30 protrudes from the wire through hole 2 into the space 4 on the other side of the vehicle body panel 1, and then, the inner protector 20 enters the wire through hole 2. Here, although the respective panel locking claws 29A of the inner protector 20 hit the peripheral edge of the wire through hole 2, the respective panel locking claws 29A are elastically deformed and allow the inner protector 20 to be inserted into the wire through hole 2. When the inner protector 20 is inserted to the insertion completion position, the respective panel locking claws 29A are elastically restored and locked to the peripheral edge of the vehicle body panel 1 on the opposite side of the electric wire passing hole 2. The vehicle body panel 1 is sandwiched by the plurality of panel locking claws 29A and the lip 15 of the grommet main body 11. This clamping force attaches the grommet 10 to the electric wire through-hole 2 of the vehicle body panel 1.
As described above, the grommet 10 according to the first embodiment includes: a grommet main body 11 for covering the electric wire W at one side of the vehicle body panel 1 and making close contact with the periphery of the electric wire through-hole 2; an inner protector 20 formed of a material having a higher rigidity than the grommet body 11, and disposed inside the grommet body 11; and a path regulating member 30, the path regulating member 30 being fixed to the inner protector 20, the path regulating member 30 regulating a path of the electric wire W drawn to the other side of the body panel 1. Thus, the path regulating member 30 is attached to the grommet 10, and the path regulating member 30 regulates the path of the electric wire W drawn out to the other side of the vehicle body panel 1, so that the electric wire W can be routed in a desired path. More specifically, as shown in fig. 5A, the electric wires W drawn out to the other side of the vehicle body panel 1 can be routed in a routing path that can avoid interference with the peripheral component 140 and ensure a necessary gap G with the peripheral component 140. As described above, in the grommet 10 according to the first embodiment, a vehicle body fixing member (e.g., a clip) as in the conventional grommet 100 is not required, and furthermore, the electric wire W can be routed in a desired path without performing difficult and troublesome work.
The path regulating member 30 is a cylindrical body for accommodating the electric wire W therein. That is, as shown in fig. 16B, in the conventional grommet 100, the electric wire W drawn out to the other side of the vehicle body panel 1 is regulated only by the position of the clip 120, and further, there is a gap from the electric wire W in the electric wire insertion path 110a in the inner protector 100. For this reason, there is a degree of freedom in the wiring path from the inner protector 110 to the position of the clip 120, and the wiring path may be shifted as indicated by a dotted line, so that the wiring path is not uniquely specified. As a result, a situation occurs in which the wire W cannot secure the necessary gap G with the peripheral component 140. On the other hand, in the grommet 10 according to the first embodiment, as shown in fig. 5B, in the electric wire W drawn out to the other side of the vehicle body panel 1, the path regulating member 30 is supported by the inner protector 20 almost without a gap, and in a section from the inner protector 20 to the tip end of the path regulating member 30, the wiring path of the electric wire W is uniquely specified without any degree of freedom due to the path regulating member 30. For this reason, the wire W can reliably secure the necessary gap G with the peripheral component 140.
The path regulating member 30 is a cylindrical body for accommodating the electric wire W therein. Therefore, the path regulating member 30 has a function of protecting the electric wire W.
Second embodiment
Fig. 6 to 12C illustrate a grommet 10A according to a second embodiment.
As shown in fig. 6 to 9C, similarly to the grommet 10 according to the first embodiment, the grommet 10A according to the second embodiment includes a grommet body 11, an inner protector 20, and a path regulating member 40, but only the configuration of the path regulating member 40 is different. Although the path regulating member 30 of the grommet 10 according to the first embodiment cannot change the wiring path of the electric wire W, the path regulating member 40 of the grommet 10A according to the second embodiment can change the wiring path of the electric wire W.
The path regulating member 40 is a cylindrical body for accommodating the electric wire W therein. In detail, the path regulating member 40 includes the fixed-side path regulating portion 41 and the movable-side path regulating portion 51 linked to the fixed-side path regulating portion 41 by the first hinge portion 50, and these are included in one member. The fixed-side path regulating section 41 includes: a fixed-side path regulating body 42; a fixed side cover 44 connected to the fixed side path regulating main body 42 by a second hinge 43; and a base flange portion 45, the base flange portion 45 being attached to the base end portions of the fixed-side path regulating body 42 and the fixed-side cover 44. The movable-side path regulating portion 51 includes a movable-side path regulating body 52 and a movable cover 54 connected to the movable-side path regulating body 52 by a third hinge portion 53.
The fixed-side path regulating portion 41 is curved in an arc shape when viewed from the closed surface side of the fixed-side cover 44. The movable-side path regulating unit 51 has a linear shape.
As shown in fig. 8, in the side surface portions of the distal end sides (portions connecting the movable-side path regulating portions 51) of both the fixed-side path regulating body 42 and the fixed-side cover 44, four first positioning holes (positioning fixing portions) 46 are provided at positions shifted left and right at regular intervals in the direction of laying the paths of the electric wires W. In the upper surface portion of the fixed-side path regulating body 42, four first positioning claws (positioning fixing portions) 47 are provided at intervals in the direction in which the paths of the electric wires W are arranged. Each of the first positioning holes 46 and a corresponding one of the first positioning claws 47 are set at a position offset with respect to the direction of laying of the path of the electric wire W, not at the same position.
On the other hand, in a side surface portion of the base end side (a portion connecting the fixed-side path regulating portion 41) of each of the movable-side path regulating body 52 and the movable-side cover 54, a second positioning claw (positioning fixing portion) 57 is provided, and the positions of the second positioning claws 57 of each of the movable-side path regulating body 52 and the movable-side cover 54 are shifted from each other in the right and left direction. In the upper surface portion of the movable-side path regulating body 52, two second positioning holes (positioning fixing portions) 56 are provided at intervals in the routing direction of the path of the electric wire W. The second positioning claw 57 and one of the second positioning holes 56 are set at positions offset in the direction of laying of the path of the electric wire W, and the second positioning claw 57 and the other second positioning hole 56 are provided at the same position in the direction of laying of the path of the electric wire W.
The second positioning claws 57 located on the left and right sides of the movable-side path regulating portion 51 can be selectively fitted into the four left and right first positioning holes 46 of the fixed-side path regulating portion 41, and in the same manner, the two second positioning holes 56 of the movable-side path regulating portion 51 can be selectively fitted into one or two of the four first positioning claws 47 of the fixed-side path regulating portion 41. In other words, selection of the positioning holes 46 and 56 and the positioning pawls 47 and 57 allows selection of four connection positions, and selection of these connection positions changes the connection angle (inclination angle) of the movable-side path regulating portion 51 with respect to the fixed-side path regulating portion 41.
For example, as shown in fig. 9A to 9C, fitting the second positioning claws 57 of the movable-side path regulating portion 51 into the first positioning holes 46 on the farthest distal end side of the fixed-side path regulating portion 41 makes the connection angle of the extending direction of the path regulating member 40 with respect to the surface of the vehicle body panel 1 "a" degree. Further, as shown in fig. 10A to 10C, the second positioning claws 57 of the movable-side path regulating portion 51 are fitted into the second first positioning holes 46 from the distal end side of the fixed-side path regulating portion 41 such that the connection angle of the extending direction of the path regulating member 40 with respect to the surface of the vehicle body panel 1 is "b" degrees (b > a).
In addition, in the grommet 10A according to the second embodiment, similarly to the grommet 10 according to the first embodiment, the path regulating member 40 is formed of a material having rigidity capable of at least maintaining its own shape while accommodating the electric wire W. The fixed-side path regulating body 42 and the movable-side path regulating body 52 include U-shaped wall surface portions extending in a desired arrangement direction of the wires W. A fixed-side wire housing chamber 48 is formed in the U-shaped wall surface portion of the fixed-side path regulating body 42. A movable-side wire housing chamber 58 is formed in the U-shaped wall surface portion of the movable-side path regulating body 52. The fixed-side cover 44 is provided so that the fixed-side electric wire accommodation chamber 48 can be opened with the second hinge portion 43. The movable-side cover 54 is provided so that the movable-side wire housing chamber 58 can be opened with the third hinge portion 53. In the closed position of the path regulating member 40, the fixed-side path regulating body 42 and the fixed-side cover 44 and the movable-side path regulating body 52 and the movable-side cover 54 are locked to each other by the locking portions 59.
Since the configurations of the grommet body 11 and the inner protector 20 of the grommet 10A according to the second embodiment are the same as those of the grommet body 11 and the inner protector 20 according to the first embodiment, the same parts in the drawings are denoted by the same reference numerals, and the description thereof will be omitted.
Next, the assembling steps of the grommet 10A according to the second embodiment will be described.
As shown in fig. 11A, with the fixed side cover 44 and the movable side cover 54 opened, the second positioning claws 57 and the second positioning holes 56 of the movable side path regulating body 52 are fitted into the optional first positioning holes 46 and the first positioning claws 47 of the fixed side path regulating body 42, respectively, and the connection position, i.e., the connection angle is determined. For example, in fig. 11A, the second positioning claws 57 and the second positioning holes 56 of the movable-side path regulating body 52 are fitted into the first positioning holes 46 and the first positioning claws 47 of the farthest distal end side of the fixed-side path regulating body 42, respectively, and the connection angle with the smallest inclination is determined.
Next, the electric wires W are routed in the fixed-side path regulating body 42 and the movable-side path regulating body 52, and the fixed-side cover 44 is closed with respect to the fixed-side path regulating body 42 as shown in fig. 11B.
Next, as shown in fig. 11C, the movable side cover 54 is closed with respect to the movable side path regulating main body 52. Thereby, as shown in fig. 11D, the second positioning claws 57 of the movable side cover 52 are fitted into the first positioning holes 46 of the fixed side cover 44.
The subsequent assembly steps are the same as those of the grommet 10 according to the first embodiment. That is, in the grommet 10A according to the second embodiment, as shown in fig. 12A and 12B, the path regulating member 40 is fixed to the inner protector 20. Next, as shown in fig. 12C, the inner protector 20 is fitted into the grommet body 11 through which the electric wire W passes. Thus, the grommet 10A is attached to the electric wire W. Next, when the grommet 10A according to the second embodiment is attached to the electric wire through hole 2 of the vehicle body panel 1 by the same steps as the grommet 10 according to the first embodiment, the assembling step is completed.
Similarly to the grommet 10 according to the first embodiment, the grommet 10A according to the second embodiment includes: a grommet main body 11 for covering the electric wire W at one side of the vehicle body panel 1 and making close contact with the periphery of the electric wire through-hole 2; an inner protector 20 formed of a material having a higher rigidity than the grommet body 11, and disposed inside the grommet body 11; and a path regulating member 40, the path regulating member 40 being fixed to the inner protector 20, the path regulating member 40 regulating a path of the electric wire W drawn to the other side of the body panel 1. Thus, the path regulating member 40 is attached to the grommet 10A, and the path regulating member 40 regulates the path of the electric wire W drawn out to the other side of the vehicle body panel 1, so that the electric wire W can be routed in a desired path. More specifically, the electric wire W drawn out to the other side of the vehicle body panel 1 can be routed in a routing path that can avoid interference with peripheral components (not shown) and ensure a necessary clearance with the peripheral components. As described above, the vehicle body fixing part (e.g., clip) as in the conventional grommet 100 is not required, and furthermore, the electric wire W can be routed in a desired path without performing difficult and troublesome work.
The path regulating member 40 is provided so that the path of the electric wire W can be changed. Therefore, even if the arrangement or the like of peripheral components (not shown) in the space 4 on the other side of the vehicle body panel 1 is changed, it is possible to solve without newly creating the path regulating member 40.
The path regulating member 40 includes a fixed-side path regulating portion 41 fixed to the inner protector 20 and a movable-side path regulating portion 51 coupled to the fixed-side path regulating portion 41. In the fixed-side path regulating portion 41 and the movable-side path regulating portion 51, a plurality of positioning fixing portions (positioning holes 46 and 56 and positioning claws 47 and 57) for changing the path of the electric wire W are provided. Therefore, selecting one of the plurality of positioning fixing portions enables the path of the electric wire W to be easily changed, and the operability is good.
The path regulating member 40 is formed of one member. Therefore, the operability and the like of the wire routing are good.
Modification example
In various embodiments, inner protector 20 includes a pair of inner members 21 that are separate from one another, but may include a pair of inner members that are interconnected by a hinge. When a pair of inner members are connected to each other, workability is better.
In each embodiment, the cutout portion 27 of the inner protector 20 is formed in a quadrangular shape when viewed from above, but any shape may be adopted as long as the shape prevents rotation of the path regulating members 30 and 40.
In the second embodiment, the path regulating member 40 is configured to be able to change the angle of the wiring path of the electric wire W to four different angles, but may be configured to be able to change the angle to two, three, five or more different angles. In addition, the angle of the wiring path of the electric wire W may be continuously changed.
In the second embodiment, the path regulating member 40 is formed of one member, but may be formed of two or more members.
