Description

Technical Field

[0001] The present disclosure relates to a wire harness.

Background Art

[0002] Conventionally, some wire harnesses include a group of electric wires routed from a vehicle body to a slide door that can be opened and closed relative to the vehicle body, and a plurality of separate covers that cover the group of electric wires (see, for example, Patent Document 1). The plurality of separate covers are arranged side by side along a connecting axis extending in the direction in which the group of electric wires extends, and are rotatably connected to each other, thereby protecting the group of electric wires while allowing the group of electric wires to bend.

[0003] Each of the separate covers has a pair of side walls, a rotating shaft portion provided near the first end of the pair of side walls, and a rotated shaft portion provided near the second end of the pair of side walls. The rotating shaft portion of an adjacent separate cover is rotatably fitted into the rotated shaft portion of the separate cover.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in the wire harness described above, there are cases where it is desirable to change the rotatable angle of a separate carrier in some parts, for example, to prevent collision with the vehicle body. In such cases, it is conceivable to change the rotatable angle of a separate carrier by changing the shape of the engagement part between adjacent separate carriers, for example, by changing the shape of a pair of side walls. However, in this case, it becomes necessary to manufacture multiple types of large parts including a pair of side walls, which presents a problem of poor manufacturability. Specifically, for example, multiple types of large molds are required to form the large parts, which leads to high costs.

[0006] The purpose of this disclosure is to provide a wire harness that can improve manufacturability. [Means for solving the problem]

[0007] The wire harness of the present disclosure comprises a group of electric wires routed from a vehicle body to a sliding door that can be opened and closed relative to the vehicle body, and a plurality of separate carriers that cover the group of electric wires and are arranged in parallel along a connecting axis in the direction of extension of the group of electric wires, and are rotatably connected to each other, wherein each of the separate carriers has a pair of side walls, a pivot shaft portion provided on the pair of side walls near the first end along the connecting axis, and a rotatable shaft portion provided on the pair of side walls near the second end along the connecting axis, into which the pivot shaft portion fits and which is connectable to the pivot shaft portion, the pivot shaft portion has a notch portion in a part of the circumferential direction on its outer circumference that determines the rotatable angle of the separate carrier, the rotatable shaft portion has a rotation restricting portion in a part of the circumferential direction that is located inside the notch, and the pivot shaft portion is formed separately from the pair of side walls and is fixed to the pair of side walls.

[0010] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. [1] The wire harness of the present disclosure comprises a group of electric wires routed from a vehicle body to a sliding door that can be opened and closed relative to the vehicle body, and a plurality of separate carriers that cover the group of electric wires and are arranged in parallel along a connecting axis in the direction of extension of the group of electric wires, and are rotatably connected to each other, wherein each of the separate carriers has a pair of side walls, a pivot shaft portion provided on the pair of side walls near the first end along the connecting axis, and a rotatable shaft portion provided on the pair of side walls near the second end along the connecting axis, into which the pivot shaft portion fits and which is connectable to the pivot shaft portion, the pivot shaft portion has a notch portion in the circumferential direction of a part of the outer circumference that determines the rotatable angle of the separate carrier, the rotatable shaft portion has a rotation restricting portion in the circumferential direction that is located inside the notch portion, and the pivot shaft portion is formed separately from the pair of side walls and is fixed to the pair of side walls.

[0011] According to this configuration, the pivot shaft portion, which has a notch that determines the rotatable angle of the separate carrier, is formed separately from the pair of side walls and is fixed to the pair of side walls. Therefore, for example, the rotatable angle of the separate carrier can be changed simply by changing the pivot shaft portion. In other words, for example, while using a large component including the pair of side walls as a common component, the rotatable angle of the separate carrier can be changed simply by changing the small component, the pivot shaft portion. This eliminates the need to manufacture multiple types of large components, for example, improving manufacturability. Specifically, for example, it eliminates the need to prepare multiple types of large molds for molding large components, thus reducing costs.

[0012] [2] In the above [1], the pair of side walls have a fixing recess, the pivot shaft has a fixing portion that fits into the fixing recess, and the fixing portion may protrude radially outward from the outer circumferential surface of the pivot shaft.

[0013] According to this configuration, the rotating shaft portion has a fixing portion that fits into a fixing recess formed in each of the pair of side walls, and the fixing portion protrudes radially outward from the outer peripheral surface of the rotating shaft portion, so that the rotating shaft portion can be firmly fixed to the pair of side walls. That is, for example, in a configuration where the fixing portion does not protrude radially outward from the outer peripheral surface of the rotating shaft portion, there is a risk that the rotating shaft portion may be damaged in a twisted manner when receiving a force that stops the rotation of the separate bearing, but this can be suppressed.

[0014] [3] In the above [1] or the above [2], the rotating shaft portion may include a front-side rotating shaft portion and a back-side rotating shaft portion respectively provided on the pair of side walls, and the front-side rotating shaft portion and the back-side rotating shaft portion may be fixed to each of the pair of side walls by different fixing structures.

[0015] According to this configuration, the rotating shaft portion includes the front-side rotating shaft portion and the back-side rotating shaft portion respectively provided on the pair of side walls, and the front-side rotating shaft portion and the back-side rotating shaft portion are fixed to each of the pair of side walls by different fixing structures, so that incorrect assembly is prevented. For example, if the fixing structures of the front-side rotating shaft portion and the back-side rotating shaft portion are completely identical, there is a risk that the angles of the two notches may be displaced by fixing the front-side rotating shaft portions to each of the pair of side walls, but this can be prevented.

[0016] [4] In any one of the above [1] to the above [3], the rotation restricting portion may be provided at a position closer to the first end portion on the rotated shaft portion. According to this configuration, the rotation restricting portion is provided at the position closer to the first end portion on the rotated shaft portion, so that it is less likely to be damaged. For example, if the rotation restricting portion is provided at a position closer to the second end portion on the rotated shaft portion, the rotation restricting portion will be connected to a portion that is easily deformed between the rotated shaft portion and the second end portion on the pair of side walls, and thus is likely to be damaged. In contrast, the rotation restricting portion is connected to the central portion that is difficult to deform on the pair of side walls, so that it is less likely to be damaged.

[0017] [5] In the above [4], the pair of side walls may have a thinned portion that is thinner than other portions between the pivoted shaft portion and the second end portion. According to this configuration, since the pair of side walls has the thinned portion thinner than other portions between the pivoted shaft portion and the second end portion, for example, the pivot shaft portion can be easily fitted to the pivoted shaft portion. In addition, in this configuration, the portion between the pivoted shaft portion and the second end portion is more easily deformed compared to a configuration that does not have the thinned portion, but since the rotation restricting portion is provided at a portion closer to the first end portion on the pivoted shaft portion, it does not easily break. That is, in the configuration having the thinned portion, the effect obtained by providing the rotation restricting portion at the portion closer to the first end portion on the pivoted shaft portion is further enhanced.

[0018] [Details of the embodiments of the present disclosure] Specific examples of the illumination system of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of description, part of the configuration may be exaggerated or simplified. In addition, the dimensional ratio of each part may differ in each drawing.

[0019] The term "perpendicular" in the present specification includes not only strictly perpendicular cases, but also substantially perpendicular cases within the range that achieves the operational effects of the present embodiment. The term "tubular" used in the description of the present specification includes not only those in which a peripheral wall is formed continuously over the entire circumference in the circumferential direction, but also those formed by combining a plurality of components into a tubular shape, and those having a notch or the like in a part of the circumferential direction such as a C-shape. The outer peripheral shape of "tubular" includes, but is not limited to, a circle, an ellipse, and a polygon having sharp or rounded corners. "Tubular" refers to a shape having a through hole in a plan view, including those where the outer peripheral shape and the inner peripheral shape of the through hole are the same, and those where the outer peripheral shape and the inner peripheral shape of the through hole are different. "Tubular" includes those having a predetermined length extending along the axial direction in which the central axis passing through the center of the through hole extends, regardless of the magnitude of the length.

[0020] In this specification, "facing" means that two surfaces or members are facing each other, and includes not only cases where they are completely facing each other, but also cases where they are partially facing each other. Furthermore, in this specification, "facing" includes both cases where another member is interposed between the two parts, and cases where nothing is interposed between the two parts.

[0021] In this specification, terms such as “first,” “second,” etc., are used solely to distinguish between subjects and do not rank them. The present invention is not limited to these examples and is shown in the claims, and all modifications within the meaning and scope equivalent to the claims are intended.

[0022] (Configuration of wire harness 20) As shown in Figures 1 to 3, the wire harness 20 includes a group of wires 21 routed from the vehicle body 30 to the sliding door 40. The group of wires 21 electrically connects a power control device (not shown) installed on the vehicle body 30 to electrical equipment (not shown) installed on the sliding door 40. The electrical equipment is, for example, a power window motor or a lock actuator, and the power control device is a device for supplying power to that electrical equipment. The vehicle body 30 has an opening 31 that can be opened and closed by the sliding door 40. The vehicle body 30 is also provided with an entry / exit step 32. The entry / exit step 32 is located in a part corresponding to the sliding door 40, and is provided in a part on the inside (upper side in Figure 1) of the opening 31, rather than the outside (lower side in Figure 1) end. The entry / exit step 32 is for the user to place their feet when getting in and out of the vehicle. The sliding door 40 is also provided so as to be able to slide forward and backward (left and right in Figure 1) of the vehicle body 30 by a mechanism (not shown). More specifically, the sliding door 40 can slide from a fully closed position (see Figure 1) towards the outside of the vehicle body 30 (lower side in Figure 1) while sliding towards the rear of the vehicle body 30 (left side in Figure 2) by a mechanism not shown, and can slide all the way to a fully open position (see Figure 3).

[0023] As shown in Figure 4, the wire harness 20 comprises a group of wires 21, multiple separate carriers 22, and rubber boots 23. Figure 4 shows a portion of the wire harness 20 in a disassembled state with one separate carrier 22 and a rubber boot 23. The group of wires 21 is made up of multiple wires bundled together, but in the figure, the individual wires are omitted and they are shown schematically as a single unit.

[0024] (Configuration of multiple separate carriers 22) Multiple separate carriers 22 are made of resin material. Multiple separate carriers 22 cover the group of electric wires 21 and are arranged side by side along a connecting axis X that runs in the direction of extension of the group of electric wires 21, while being rotatably connected to one another. The connecting axis X referred to here is the axis that runs along the group of electric wires 21 when it is in a straight state.

[0025] As shown in Figures 5 and 6, each of the multiple separate carriers 22 has a separate carrier body 50 and a carrier cover 70. The figures also show a connecting axis X, a connecting cross axis Y that intersects the connecting axis X and is perpendicular to the connecting axis X, and a parallel axis Z that is perpendicular to the connecting axis X and the connecting cross axis Y.

[0026] The separate carrier body 50 is formed in a U-shape that opens along the connecting cross axis Y, by having a back wall 51 and a pair of side walls 52 that extend opposite each other from both ends of the back wall 51. In other words, the separate carrier body 50 is formed in a U-shape when viewed along the connecting axis X.

[0027] Furthermore, the carrier cover 70, while fixed to the separate carrier body 50, has a plate-like portion 71 that closes the opening of the U-shaped separate carrier body 50. That is, the carrier cover 70 has a plate-like portion 71 that is positioned to connect the ends of a pair of side walls 52.

[0028] The separate carrier body 50 has an engaging portion 53 on each of its pair of side walls 52. The carrier cover 70 has an engaging portion 72 that is fixed to the engaging portion 53 by sliding along the connecting axis X.

[0029] More specifically, the engaging portion 72 engages with the engaged portion 53 when the carrier cover 70 is first moved along the connecting cross axis Y relative to the separate carrier body 50, and then slid along the connecting axis X, thereby fixing the carrier cover 70 to the separate carrier body 50.

[0030] Furthermore, the separate carrier body 50 has a pivot shaft portion 54 and a rotated shaft portion 55. The pivot shaft portion 54 is provided on a pair of side walls 52 near the first end 52a along the connecting axis X. The rotated shaft portion 55 is provided on a pair of side walls 52 near the second end 52b along the connecting axis X. The rotated shaft portion 55 can be connected to the pivot shaft portion 54 by fitting the pivot shaft portion 54 of an adjacent separate carrier 22 into it.

[0031] The pivot shaft portion 54 protrudes from the outer surfaces of the pair of side walls 52 along the parallel axis Z. The pivot shaft portion 54 is formed in a cylindrical shape and has a notch portion 56 in a part of the circumferential direction on its outer circumference for determining the rotatable angle of the separate carrier 22.

[0032] In this embodiment, the notch 56 is cut out over a 90° range on the outer circumferential surface of the pivot shaft portion 54. Furthermore, the notch 56 in this embodiment is cut out in a straight line from the axis center of the pivot shaft portion 54 to the outer circumference. Furthermore, the notch 56 in this embodiment is cut out so as to open toward the first end 52a of the pair of side walls 52. In addition, the pivot shaft portion 54 in this embodiment has a shaft inclined surface 57 whose height gradually decreases toward the first end 52a of the pair of side walls 52.

[0033] The rotating shaft portion 55 is a hole that penetrates a pair of side walls 52. The rotating shaft portion 55 has a rotation restricting portion 58 in a part of its circumferential direction. The rotation restricting portion 58 is positioned inside the notch 56 in the adjacent separate carrier 22.

[0034] The rotation restricting portion 58 is provided on the rotating shaft portion 55 at a point on the pair of side walls 52 near the first end 52a. That is, the rotation restricting portion 58 protrudes from the point on the rotating shaft portion 55 near the first end 52a toward the axis of the rotating shaft portion 55. In this embodiment, the rotation restricting portion 58 protrudes toward the axis from a 45° range on the inner circumferential surface of the rotating shaft portion 55.

[0035] Furthermore, the pair of side walls 52 have a thin-walled portion 59 between the pivoted shaft portion 55 and the second end portion 52b, which is thinner than the other portions. The thin-walled portion 59 is formed by recesses provided on the opposing surfaces of the pair of side walls 52. The thin-walled portion 59 is formed to gradually become thinner from the pivoted shaft portion 55 toward the second end portion 52b.

[0036] Here, as shown in Figure 5, the pivot shaft portion 54 is formed separately from a pair of side walls 52 and is fixed to the pair of side walls 52. More specifically, the pair of side walls 52 have fixing recesses 60, and the pivot shaft portion 54 has fixing portions 61 that fit into the fixing recesses 60. The fixing portions 61 protrude radially outward from the outer circumferential surface of the pivot shaft portion 54. In this embodiment, the fixing portions 61 are three fixing portions 61 that extend radially from the axis center of the pivot shaft portion 54, and each of the three fixing portions 61 is formed to protrude radially outward from the outer circumferential surface of the pivot shaft portion 54. Of course, there are three fixing recesses 60 so that the three fixing portions 61 can fit into them. The fixing portions 61 in this embodiment are fitted into the fixing recesses 60 and fixed to the fixing recesses 60 by adhesive.

[0037] Furthermore, the pivot shaft portion 54 includes a front pivot shaft portion 541 and a back pivot shaft portion 542, which are provided on each of the pair of side walls 52. The front pivot shaft portion 541 and the back pivot shaft portion 542 are fixed to each of the pair of side walls 52 by different fixing structures. In this embodiment, the front pivot shaft portion 541 and the back pivot shaft portion 542 are formed with different fixing structures by slightly different spacing between the fixing portions 61 and the circumferential width of the fixing portions 61. Of course, the fixing recesses 60 provided on each of the pair of side walls 52 are also made of different shapes according to the fixing portions 61. This configuration prevents, for example, the front pivot shaft portion 541 from being fixed to both of the pair of side walls 52.

[0038] As shown in Figures 7 and 8, the wire harness 20 of this embodiment has two types of separate carriers 22: a first separate carrier 22A (see Figure 7) and a second separate carrier 22B (see Figure 8), each with a different rotatable angle. The first separate carrier 22A has a first pivot shaft portion 54A (see Figure 7), and the second separate carrier 22B has a second pivot shaft portion 54B (see Figure 8). The notches 56A (see Figure 7) in the first pivot shaft portion 54A and the notches 56B (see Figure 8) in the second pivot shaft portion 54B have different shapes. That is, the range of the notches 56A with respect to the connecting axis X and the range of the notches 56B with respect to the connecting axis X are set to be different.

[0039] As a result, as shown in Figure 7, the first separate carrier 22A is rotatable 15° counterclockwise in the first rotation direction from a straight position, and 30° clockwise in the second rotation direction from a straight position. Furthermore, as shown in Figure 8, the second separate carrier 22B is not rotatable counterclockwise in the first rotation direction from a straight position, and is rotatable 45° clockwise in the second rotation direction from a straight position.

[0040] The multiple separate carriers 22 are arranged such that the wire harness 20 does not protrude beyond the overhang prevention line L (see Figure 3) towards the vehicle body 30 (upper side in Figure 3). The first separate carrier 22A and the second separate carrier 22B are combined to achieve this. The overhang prevention line L is, for example, a line set for each vehicle model to maintain a certain distance from the vehicle body 30.

[0041] As shown in Figure 3, in this embodiment, for example, a second separate carrier 22B (see Figure 8) is used in the intermediate range A of the wire harness 20. This prevents the wire harness 20 from protruding beyond the overhang prevention line L towards the vehicle body 30 (upper side in Figure 3). Therefore, the wire harness 20 is prevented from colliding with the vehicle body 30. In areas of the wire harness 20 other than the intermediate range A, a first separate carrier 22A (see Figure 7) is used. Of course, the combination of the first separate carrier 22A and the second separate carrier 22B may be appropriately changed according to, for example, the overhang prevention line L set for each vehicle model.

[0042] (Composition of rubber boots 23) The rubber boot 23 is made of rubber material. As shown in Figure 4, the rubber boot 23 is provided to cover a plurality of rotatably connected separate carriers 22. The rubber boot 23 is formed in a cylindrical shape and has a bellows structure by repeating indentations and protrusions in the extending direction. The rubber boot 23 is formed to be easily bent by the bellows structure, allowing the plurality of separate carriers 22 to rotate.

[0043] (Operation of this embodiment) Next, we will explain the operation of the wire harness 20 configured as described above. As shown in Figures 1 to 3, when the sliding door 40 slides forward and backward on the vehicle body 30, the wire harness 20 deforms. At this time, the group of wires 21 deforms while being protected by the separate carriers 22 as the multiple separate carriers 22 rotate relative to each other. Furthermore, by employing a first separate carrier 22A (see Figure 7) and a second separate carrier 22B (see Figure 8), the wire harness 20 is prevented from protruding beyond the overhang prevention line L (see Figure 3) towards the vehicle body 30.

[0044] (Effects of this embodiment) Next, the effects of the above embodiment are described below. (1) The pivot shaft portion 54, which has a notch 56 that determines the rotatable angle of the separate carrier 22, is formed separately from the pair of side walls 52 and is fixed to the pair of side walls 52. Therefore, for example, the rotatable angle of the separate carrier 22 can be changed simply by changing the pivot shaft portion 54. In other words, for example, the rotatable angle of the separate carrier 22 can be changed simply by changing the pivot shaft portion 54, which is a small part, while using the separate carrier body 50, which is a large part including the pair of side walls 52, as a common part. This eliminates the need to manufacture multiple types of large parts, for example, improving manufacturability. Specifically, for example, it eliminates the need to prepare multiple types of large molds for molding large parts, thus reducing costs.

[0045] (2) The pivot shaft portion 54 has a fixing portion 61 that fits into a fixing recess 60 of a pair of side walls 52, and the fixing portion 61 protrudes radially outward from the outer circumferential surface of the pivot shaft portion 54, so that the pivot shaft portion 54 can be firmly fixed to the pair of side walls 52. That is, for example, in a configuration in which the fixing portion 61 does not protrude radially outward from the outer circumferential surface of the pivot shaft portion 54, there is a risk that the pivot shaft portion 54 may break by twisting when subjected to a force that stops the rotation of the separate carrier 22, but this can be suppressed.

[0046] (3) The pivot shaft portion 54 includes a front pivot shaft portion 541 and a back pivot shaft portion 542 provided on each of the pair of side walls 52, and the front pivot shaft portion 541 and the back pivot shaft portion 542 are fixed to each of the pair of side walls 52 by different fixing structures, thereby preventing incorrect assembly. For example, if the fixing structures of the front pivot shaft portion 541 and the back pivot shaft portion 542 are exactly the same, there is a risk that the angles of the two notches 56 will be misaligned when the front pivot shaft portion 541 is fixed to each of the pair of side walls 52, but this can be prevented.

[0047] (4) The rotation restricting part 58 is provided on the rotating shaft portion 55 near the first end portion 52a, making it less susceptible to damage. For example, if the rotation restricting part 58 were provided on the rotating shaft portion 55 near the second end portion 52b, the rotation restricting part 58 would be connected to a deformable portion between the rotating shaft portion 55 and the second end portion 52b in the pair of side walls 52, making it more susceptible to damage. In contrast, the rotation restricting part 58 is connected to the central portion of the pair of side walls 52, which is less prone to deformation, making it less susceptible to damage.

[0048] (5) The pair of side walls 52 have a thin-walled portion 59 between the rotating shaft portion 55 and the second end portion 52b, which is thinner than other parts, making it easier to fit the rotating shaft portion 54 into the rotating shaft portion 55, for example. In this configuration, the portion between the rotating shaft portion 55 and the second end portion 52b is more prone to deformation compared to a configuration without the thin-walled portion 59, but the rotation restricting portion 58 is provided in the rotating shaft portion 55 closer to the first end portion 52a, so it is not prone to breakage. In other words, in a configuration with the thin-walled portion 59, the effect of providing the rotation restricting portion 58 in the rotating shaft portion 55 closer to the first end portion 52a is greater.

[0049] (Example of change) The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0050] In the above embodiment, the pair of side walls 52 have a fixing recess 60 and the pivot shaft portion 54 has a fixing portion 61 that fits into the fixing recess 60, but the invention is not limited to this. For example, the pivot shaft portion 54 may be fixed to the pair of side walls 52 by another fixing structure, even if the fixing recess 60 and the fixing portion 61 that fits into the fixing recess 60 are not present. Also, in the above embodiment, the fixing portion 61 is fixed to the fixing recess 60 by adhesive while being fitted into the fixing recess 60, but the invention is not limited to this, and for example, the fixing portion 61 may be fixed by press-fitting it into the fixing recess 60.

[0051] In the above embodiment, the fixed portion 61 is assumed to protrude radially outward from the outer circumferential surface of the pivot shaft portion 54, but this is not limited to this configuration. For example, the fixed portion 61 may not protrude radially outward from the outer circumferential surface of the pivot shaft portion 54.

[0052] In the above embodiment, the front pivot shaft portion 541 and the rear pivot shaft portion 542 are fixed to each of the pair of side walls 52 by different fixing structures, but this is not limited to this. For example, the front pivot shaft portion 541 and the rear pivot shaft portion 542 may be fixed to each of the pair of side walls 52 by the same fixing structure. That is, for example, the front pivot shaft portion 541 may be fixed to both of the pair of side walls 52.

[0053] In the above embodiment, the rotation restricting portion 58 is provided on the rotated shaft portion 55 near the first end portion 52a, but it is not limited to this, and for example, it may be provided on the rotated shaft portion 55 near the second end portion 52b. That is, the rotation restricting portion 58 may be connected by a pair of side walls 52 to the portion between the rotated shaft portion 55 and the second end portion 52b.

[0054] In the above embodiment, the pair of side walls 52 have a thin-walled portion 59 between the pivoted shaft portion 55 and the second end portion 52b, which is thinner than the other portions. However, the embodiment is not limited to this, and a configuration without a thin-walled portion 59 is also possible.

[0055] In the above embodiment, a pivot shaft portion 54 having a notch 56 is provided on each of the pair of side walls 52, but the invention is not limited to this, and the pivot shaft portion 54 having the notch 56 may be provided on only one of the pair of side walls 52.

[0056] In the above embodiment, the pivoted shaft portion 55 is a hole that penetrates a pair of side walls 52, but it may be changed to another shape as long as the pivoted shaft portion 54 can be rotatably fitted into it. For example, it may be a non-penetrating recess into which the pivoted shaft portion 54 fits.

[0057] In the above embodiment, the carrier cover 70 is fixed to the separate carrier body 50 by first moving along the connecting cross axis Y and then sliding along the connecting axis X. However, the invention is not limited to this, and other fixing structures may be used.

[0058] For example, the separate carrier body 50 may have locking claws that protrude along the connecting cross axis Y, and the carrier cover 70 may have locking holes that engage with the locking claws, and may be fixed by moving along the connecting cross axis Y relative to the separate carrier body 50.

[0059] In the above embodiment, the wire harness 20 is provided with two types of separate carriers 22, namely a first separate carrier 22A and a second separate carrier 22B, each with a different rotatable angle.
