Further, there is an example in which the first wiring member 20 includes a high-voltage power supply line and the second wiring member 30 includes a lower-voltage power supply line. Here, the first wiring member 20 includes a power supply line, the second wiring member 30 is a cable for in-vehicle LAN communication, and particularly here, the second wiring member 30 is a high-speed that conforms to the Ethernet (registered trademark) standard. The description will be made assuming that the cable is for communication. The first wiring member 20 and the second wiring member 30 are spaced apart to reduce the influence of the noise.

The sheet-like interval maintaining member 40 is formed in a shape in which sheet-like portions are continuous along the extending direction of the first wiring member 20 and the second wiring member 30. A plurality of first holding portions 42 and a plurality of second holding portions 46 are formed in the sheet-like interval maintaining member 40. A plurality of portions of the first wiring member 20 that are spaced along the extending direction are disposed in the plurality of first holding portions 42 to hold the first wiring member 20, and the second wiring Among the members 30, a plurality of positions spaced apart along the extending direction are disposed in the plurality of second holding portions 46, and the second wiring member 30 is held. Thereby, the 1st wiring member 20 and the 2nd wiring member 30 are hold | maintained in parallel state at intervals.

More specifically, the sheet-like interval maintaining member 40 is formed in an elongated sheet shape. It is preferable that the sheet-like interval maintaining member 40 is formed of a sheet-like member that is rigid to the extent that the interval can be maintained between the first wiring member 20 and the second wiring member 30. In consideration of the manufacturing process described later, the sheet-like interval maintaining member 40 is formed of a sheet-like member that can be bent and deformed, and more preferably, the sheet-like interval maintaining member 40 can be bent without being broken. It is preferable that it is formed by. Examples of such a sheet-like member include a PP (polypropylene) sheet, a PVC (polyvinyl chloride) sheet, or a PET (polyethylene terephthalate) sheet, such as a resin sheet material in which the inside is uniformly filled with a resin, a plastic cardboard, and the like. A hollow plate material or the like can be used. Moreover, the sheet-like member which gave the rigidity by pressing and hardening a nonwoven fabric etc. can also be used. Further, as the sheet-like member, a member provided with conductivity by metal vapor deposition, metal plating, or the like may be used.

In the present embodiment, the sheet-like interval maintaining member 40 is formed in a rectangular sheet shape extending on one plane.

The plurality of first holding portions 42 are formed so as to be arranged in a line at intervals along the extending direction of the sheet-like interval maintaining member 40. Each first holding part 42 is formed in a hole shape penetrating the one main surface and the other main surface of the sheet-like interval maintaining member 40. In a state where the first wiring member 20 is disposed in the first holding portion 42, the peripheral portion of the first holding portion 42 surrounds the entire periphery of the first wiring member 20 without a break. As a shape of the 1st holding | maintenance part 42, it is assumed that it is shapes, such as a round hole and an elliptical hole.

The first wiring member 20 passes through the plurality of first holding portions 42, that is, passes from one main surface side of the sheet-like interval maintaining member 40 to the other main surface side and the other main portion of the sheet-like interval maintaining member 40. Passing from the surface side to the one main surface side is alternately repeated along the direction in which the plurality of first holding portions 42 are arranged, and alternately disposed on the one surface side and the other main surface side of the sheet-like interval maintaining member 40. The Here, the sheet-like interval maintaining member 40 is formed in a rectangular sheet shape extending on one plane, and the first wiring member 20 passes through the plurality of first holding portions 42 alternately in the opposite direction, and the sheet It arrange | positions so that it may meander on both surfaces side of the shape space | interval maintenance member 40.

The plurality of second holding portions 46 are formed so as to be arranged in a line at intervals along the extending direction of the sheet-like interval maintaining member 40. Each of the second holding portions 46 is formed in a hole shape penetrating the one main surface and the other main surface of the sheet-like interval maintaining member 40. In a state where the second wiring member 30 is disposed in the second holding portion 46, the peripheral portion of the second holding portion 46 surrounds the entire periphery of the second wiring member 30 without any breaks. As a shape of the 2nd holding | maintenance part 46, it is assumed that it is shapes, such as a round hole and an elliptical hole. In addition, when the 1st holding | maintenance part 42 or the 2nd holding | maintenance part 46 is formed in the hole shape long in one direction, it is preferable that the longitudinal direction corresponds with the longitudinal direction of the sheet-like space | interval maintenance member 40.

The second wiring member 30 passes through the plurality of second holding portions 46, that is, passes from one main surface side of the sheet-like interval maintaining member 40 to the other main surface side and the other main portion of the sheet-like interval maintaining member 40. Passing from the surface side to the one main surface side is alternately repeated along the direction in which the plurality of second holding portions 46 are arranged, and alternately disposed on the one surface side and the other main surface side of the sheet-like interval maintaining member 40. The Here, the sheet-like interval maintaining member 40 is formed in a rectangular sheet shape extending on one plane, and the second wiring member 30 alternately passes through the plurality of second holding portions 46 in the opposite direction, The sheet-like interval maintaining member 40 is disposed so as to meander on both sides.

The plurality of first holding portions 42 and the plurality of second holding portions 46 are formed at positions spaced in the width direction of the sheet-like interval maintaining member 40. Therefore, the first wiring member 20 held by the plurality of first holding portions 42 and the second wiring member 30 held by the plurality of second holding portions 46 are spaced in the width direction of the sheet-like interval maintaining member 40. Is held open.

In the present embodiment, the plurality of first holding portions 42 and the plurality of second holding portions 46 are repeatedly formed at substantially the same periodic intervals. The first wiring member 20 and the second wiring member 30 are disposed on one main surface side of the sheet-like interval maintaining member 40 at substantially the same position in the longitudinal direction of the sheet-like interval maintaining member 40, and the sheet at the same substantially same position. It is disposed on the other main surface side of the shape interval maintaining member 40. That is, the first wiring member 20 and the second wiring member 30 are arranged to meander at substantially the same cycle. However, the first wiring member 20 and the second wiring member 30 are separately arranged on one main surface side and the other main surface side of the sheet-like interval maintaining member 40 at substantially the same position in the longitudinal direction of the sheet-like interval maintaining member 40. Similarly, the sheet-like interval maintaining member 40 may be arranged separately at one main surface side and the other main surface side at substantially the same position. That is, the 1st wiring member 20 and the 2nd wiring member 30 may be arrange | positioned so that it may meander with a substantially reverse period shift | offset | difference.

The sheet-like interval maintaining member 40 is formed with a plurality of folds 41 in the extending direction. The plurality of folds 41 are formed at positions where the plurality of first holding portions 42 can be disposed so as to overlap each other and the plurality of second holding portions 46 can be disposed so as to overlap each other. More specifically, the fold line 41 is a fold line 41 along the width direction of the sheet-like interval maintaining member 40, and the fold line 41 after being mountain-folded along the extending direction of the sheet-like interval maintaining member 40 The folds 41 after the valley fold are alternately formed. Each fold 41 is located between each of the plurality of first holding portions 42 and between each of the plurality of second holding portions 46 in the extending direction of the sheet-like interval maintaining member 40. When the sheet-like interval maintaining members 40 are alternately folded along the fold lines 41, the plurality of first holding portions 42 overlap to form a continuous opening, and the plurality of second holding portions 46 overlap. To form a continuous opening (described in detail later).

While the first wiring member 20 is held by the plurality of first holding portions 42 and the second wiring member 30 is held by the plurality of second holding portions 46, the first wiring member 20, the second wiring member A bundling member 50 such as an adhesive tape is wound around the 30 and the sheet-like interval maintaining member 40 and held in an integrated form.

The sheet-like interval maintaining member 40 may be provided in the entire extending direction of the first wiring member 20 and the second wiring member 30 or may be provided in a part of the extending direction.

According to the wire harness 10 or the sheet-like interval maintaining member 40 configured as described above, the first wiring member 20 held by the plurality of first holding portions 42 of the sheet-like interval maintaining member 40 and the plurality of second holding portions. The second wiring member 30 held at 46 is maintained in a state of being spaced according to the distance between the first holding part 42 and the second holding part 46. The interval between the first wiring member 20 and the second wiring member can be easily adjusted by appropriately adjusting the distance between the first holding portion 42 and the second holding portion 46 in the sheet-like interval maintaining member 40. For this reason, the 1st wiring member 20 and the 2nd wiring member 30 can be arrange | positioned with a desired spatial distance between them.

As a method for suppressing the influence of electromagnetic noise between the wiring members, it is assumed to use a shielded wire having a metal braid or the like formed on the outer periphery. However, the use of such a shielded wire is expensive. In contrast, in the wire harness 10, the influence of noise is suppressed by providing a spatial distance between the first wiring member 20 and the second wiring member 30. Thereby, the influence of the noise between the 1st wiring member 20 and the 2nd wiring member 30 can be reduced, suppressing a cost increase. Of course, shielded wires may be adopted as the wires constituting the first wiring member 20 and the second wiring member 30, or a shield layer may be provided between them.

Moreover, since the 1st wiring member 20 is alternately arrange | positioned on the one main surface and the other main surface of the sheet-like space | interval maintenance member 40 via the some 1st holding | maintenance part 42, it is more reliably in a fixed position. Kept. In addition, the second wiring member 30 is also alternately disposed on one main surface and the other main surface of the sheet-like interval maintaining member 40 via the plurality of second holding portions 46, so that the second wiring member 30 is more reliably held at a certain position. Be drunk. As a result, the 1st wiring member 20 and the 2nd wiring member 30 can be arrange | positioned at intervals more reliably.

Further, since the plurality of first holding portions 42 and the plurality of second holding portions 46 are formed at positions spaced in the width direction of the sheet-like interval maintaining member 40, the width direction of the sheet-like interval maintaining member 40 In FIG. 1, the first wiring member 20 and the second wiring member 30 can be more reliably disposed with a space therebetween.

Moreover, since the 1st wiring member 20 and the 2nd wiring member 30 are arrange | positioned so that it may meander on the both surface sides of the sheet-like space | interval maintenance member 40, the straight state (here flat surface) of the sheet-like space maintenance member 40 is arrange | positioned. State). For this reason, the sheet-like interval maintaining member 40 can be used without being bent so much, and the amount of use (length dimension) can be reduced.

In addition, since the plurality of first holding portions 42 and the plurality of second holding portions 46 are formed in a hole shape surrounding the entire periphery of the first wiring member 20 or the second wiring member 30, the first wiring member 20 and The second wiring member 30 is unlikely to be detached from the plurality of first holding portions 42 or the plurality of second holding portions 46. For this reason, the 1st wiring member 20 and the 2nd wiring member 30 can be maintained in a fixed position more reliably.

Further, if the sheet-like interval maintaining member 40 is the fold line 41, a plurality of first holding portions 42 can be arranged to overlap each other, and a plurality of second holding portions 46 can be arranged to overlap each other. it can. As will be described later, the first wiring member 20 can be easily disposed in the plurality of first holding portions 42, and the second wiring member 30 can be easily disposed in the plurality of second holding portions 46. Can do.

<About the manufacturing method of the wire harness 10>

The creases 41 are along the width direction of the sheet-like member 40B1, and are provided at equal intervals in the extending direction of the sheet-like member 40B1. As a result, the sheet-like member 40B1 is folded at the fold line 41 and folded into a plurality of layers. A plurality of first holding portions 42 and a plurality of second holding portions 46 are formed on the sheet-like member 40B1 by a punching die 60. Since the sheet-like member 40B1 is folded into a plurality of layers, the plurality of first holding portions 42 can be formed in a single operation by a single punching operation using the punching die 60. Similarly, the plurality of first holding members The portions 42 can be formed in a lump.

The sheet-like interval maintaining member 40B2 in which the plurality of first holding portions 42 and the plurality of second holding portions 46 are formed is as shown in FIG. In this sheet-like interval maintaining member 40B2, it is folded at a plurality of folds 41, and a plurality of first holding portions 42 are arranged so as to be positioned substantially on the same straight line, and a plurality of second The holding portions 46 are arranged so as to overlap with each other so as to be positioned on substantially the same straight line. In this manner, the step of folding the sheet-like interval maintaining member 40B2 so as to overlap the plurality of first holding portions 42 and the plurality of second holding portions 46 is performed (step (b) )). In addition, in the said process, after forming the 1st holding | maintenance part 42 and the 2nd holding | maintenance part 46, you may fold sheet-like space | interval maintenance member 40B2.

Then, the one end portion of the first wiring member 20 is passed through the plurality of first holding portions 42 with respect to the folded sheet-like interval maintaining member 40B2, and the one end portion of the second wiring member 30 is passed through the plurality of first holding portions 42. 2 Pass through the holding part 46 (step (b)). Then, as shown in FIG. 6, the first wiring member 20 extends to both sides through the plurality of first holding portions 42 of the folded sheet-like interval maintaining member 40B2, and the second wiring member 30 is folded. It will be in the state extended to the both sides through several 2nd holding | maintenance parts 46 of sheet-like space | interval maintenance member 40B2.

Next, the first wiring member 20 is disposed in the plurality of first holding portions 42, and the second wiring member 30 is disposed in the second holding portion 46, and is folded in a sheet shape. The distance maintaining member 40B2 is extended (see the arrow in FIG. 6). That is, the both ends of the sheet-like interval maintaining member 40B2 are gripped and stretched so as to be pulled toward both ends of the first wiring member 20 and the second wiring member 30 (step (c)). Then, the sheet-like interval maintaining member 40B2 is pulled to form the sheet-like interval maintaining member 40 until the sheet-like interval maintaining member 40B2 extends on substantially the same plane. When the wiring member 20, the second wiring member 30, and the sheet-like interval maintaining member 40 are bundled, the wire harness 10 is manufactured.

According to the manufacturing method of the wire harness 10 and the sheet-like interval maintaining member 40B2 configured as described above, in the folded sheet-like interval maintaining member 40B2, a plurality of first holding portions 42 are disposed to overlap each other. Since the plurality of second holding portions 46 are folded and arranged, the first wiring member 20 can be easily arranged in the plurality of first holding portions 42, and the plurality of second wiring members 30 are arranged. The second holding part 46 can be easily arranged. And the 1st wiring member 20 and the 2nd wiring member 30 can be maintained in the state which opened the space | interval over comparatively long dimension by extending the folded sheet | seat form space | interval maintenance member 40B2.

<About modification>
Based on the above embodiment, various modifications will be described.

7 and 8 are views showing a wire harness 110 according to a first modification. In the wire harness 110, the first wiring member 120 corresponding to the first wiring member 20 and the second wiring member 130 corresponding to the second wiring member 30 are arranged in a straight line. The sheet-like interval maintaining member 140 corresponding to the sheet-like interval maintaining member 40 is formed in a bent shape so as to meander through a plurality of curved portions 141. Here, the sheet-like interval maintaining member 140 has a curved portion 141 that bends toward one main surface side of the sheet-like interval maintaining member 140 and the other main surface side of the sheet-like interval maintaining member 140. The curved portions 141 that bend so as to be convex are formed in a shape alternately arranged along the extending direction of the sheet-like interval maintaining member 140. Further, the first holding portion 42 and the second holding portion 46 are formed at the boundary portions of the curved portions 141 at intervals along the width direction of the sheet-like interval maintaining member 140. The first wiring member 20 is held by the plurality of first holding portions 42, and the second wiring member 30 is held by the plurality of second holding portions 46, thereby allowing the first wiring member 20 and the second wiring to be held. The members are held in parallel with a gap. The first wiring members 20 and the second wiring members 30 are disposed on the inner peripheral side portions of the curved portions 141 and extend in a straight line state.

In the first modification, like the wire harness 210 shown in the second modification shown in FIG. 9, the first holding part 242 corresponding to the first holding part 42 and the second holding part corresponding to the second holding part 46. The position of the portion 246 is perpendicular to the width direction of the sheet-like interval maintaining member 240 corresponding to the sheet-like interval maintaining member 140 and the extending direction of the first wiring member 20 and the second wiring member 30 (sheet-like shape). It is preferable to shift the distance maintaining member 240 in the thickness direction).

Thereby, the 1st wiring member 20 and the 2nd wiring member 30 are shifted and arranged in the up-and-down direction of sheet-like space maintenance member 240, too. For this reason, the interval S2 between the first wiring member 20 and the second wiring member 30 can be made larger than the interval S1 when they are provided without being displaced in the vertical direction, and the influence of noise is further increased. Can be reduced.

In addition, an intermediate aspect between the above embodiment and the first modification, that is, the first wiring member 20 and the second wiring member 30 meander to a more gentle degree than in the above embodiment, and a sheet-like interval maintaining member. 140 may meander to a gentler degree than the case of the first modified example, and these may be combined with a half-cycle shift from each other. Further, the first wiring member 20, the second wiring member 30, or the sheet-like interval maintaining member 140 may meander at a steeper angle (for example, zigzag).

FIG. 10 is a schematic perspective view showing a wire harness 310 according to a third modification (however, FIG. 10 shows a form in the middle of manufacture). In this wire harness 310, instead of the first holding portion 42, a first holding portion 342 is formed that surrounds the periphery of the first wiring member 20 and is formed in a concave shape in which a part of the periphery is divided. . More specifically, the first holding portion 342 is formed with holes penetrating on both sides of the sheet-like interval maintaining member 340 corresponding to the sheet-like interval maintaining member 40, and around the hole. Among them, the sheet-like interval maintaining member 340 is divided on one side edge side and connected to the outside. Further, in place of the second holding portion 46, a second holding portion 346 is formed which has a concave shape that surrounds the periphery of the second wiring member 30 and is partially cut off. More specifically, the second holding portion 346 is formed with holes penetrating on both sides thereof on the other side portion of the sheet-like interval maintaining member 340 corresponding to the sheet-like interval maintaining member 40 and around the hole. Among them, the sheet-like interval maintaining member 340 is divided on the other side edge side and connected to the outside.

For this reason, the first wiring member 20 can be disposed in each first holding portion 342 through the divided portions outside the plurality of first holding portions 342 in a state where the sheet-like interval maintaining member 340 is folded, Similarly, the second wiring member 30 can be disposed in each second holding portion 346 through a divided portion outside the plurality of second holding portions 346. Even in these cases, in the form of the wire harness 310, the first wiring member 20 is held in each first holding portion 342, and the second wiring member 30 is held by each second holding portion 346. . For this reason, the 1st wiring member 20 and the 2nd wiring member 30 can be easily arrange | positioned in each 1st holding | maintenance part 342 and each 2nd holding | maintenance part 346. In particular, since it is not necessary to pass the end portions of the first wiring member 20 and the second wiring member 30 through the holes, this is effective when a connector or the like is connected to these end portions.

FIG. 11 is a schematic perspective view showing a wire harness 410 according to a fourth modified example (however, FIG. 11 shows a form in the middle of manufacture). In the wire harness 410, a second holding portion 346B is formed instead of the second holding portion 346 in the wire harness 310. The second holding part 346B differs from the second holding part 346 in that the second holding part 346B is divided not at the side of the sheet-like interval maintaining member 340B corresponding to the sheet-like interval maintaining member 340 but at the fold 41 side. Is connected to the outside. For this reason, the 2nd wiring member 30 is arrange | positioned in each 2nd holding | maintenance part 346B from the fold 41 side of the folded sheet-like space | interval maintenance member 340. FIG. Thereby, the same effect as the said 3rd modification can be obtained.

The shape of the first holding portion 342 and the second holding portion 346 and 346B and the shape of the divided portion are not particularly limited, and therefore, the first holding portion 342 and the second holding portion 346B are opened to the side of the sheet-like interval maintaining member 340 or the fold 41 side. The shape may be a concave shape that is recessed in a shape, a shape that is recessed in a semicircular shape, or the like. However, in order to suppress the drop-off of the first wiring member 20 and the second wiring member 30, the divided portions of the first holding part 342 and the second holding parts 346 and 346B are the first wiring member 20 or It is preferable that the second wiring member 30 is formed to be narrower than the portion where the second wiring member 30 is disposed.

12 and 13 are views showing a wire harness 510 according to a fifth modification. The wire harness 510 includes a third wiring member 550 arranged in parallel with the first wiring member 20 and the second wiring member 30. The sheet-like interval maintaining member 540 corresponding to the sheet-like interval maintaining member 40 includes a plurality of third holding portions that hold the third wiring member 550 between the first wiring member 20 and the second wiring member 30. 548 is formed. That is, the third holding part 548 is formed between the first holding part 42 and the second holding part 46 in the width direction of the sheet-like interval maintaining member 540. The third holding member 548 is disposed in a state where the sheet-like interval maintaining member 540 is folded, and the third wiring member 550 is disposed in the same manner as the first wiring member 20 and the second wiring member 30. Is passed through the plurality of third holding portions 548. Thereafter, the sheet-like interval maintaining member 540 is extended. Accordingly, the third wiring member 550 is disposed in the third holding portion 548 at a plurality of positions spaced apart in the longitudinal direction of the third wiring member 550, so that the third wiring member 550 is connected to the first wiring member 20 and the second wiring member 30. Held between. The wire harness 510 is manufactured by binding the binding member 50 such as an adhesive tape around the first wiring member 20, the second wiring member 30, the third wiring member 550, and the sheet-like interval maintaining member 540. .

According to this modification, in addition to the operational effects of the above embodiment, the third wiring member 550 is disposed between the first wiring member 20 and the second wiring member 30, so that the third wiring member 550 In addition, the first wiring member 20 and the second wiring member 30 can be maintained in a state of being more reliably spaced apart.

The third wiring member 550 is less affected by noise on the second wiring member 30 than the first wiring member 20, and is affected by noise received from the first wiring member 20 rather than the second wiring member 30. Is preferably small. As such a combination of the first wiring member 20, the second wiring member 30, and the third wiring member 550, for example, the first wiring member 20 is a high-voltage power supply line, and the second wiring member 30 is a signal. And a combination in which the third wiring member 550 is a low-voltage power supply line. Further, for example, the first wiring member 20 is a power supply line, the second wiring member 30 is a signal line that is susceptible to noise such as a signal line for high-speed communication, and the third wiring member 550 is a signal for a sensor. A combination that is a signal line that is not easily affected by noise, such as a line or a signal line for low-speed communication, can be considered.

14 and 15 are views showing a wire harness 610 according to a sixth modification. The wire harness 610 has a configuration in which a side extension cover 642 is extended on one side of a portion 640P corresponding to the sheet-like interval maintaining member 40 as the sheet-like interval maintaining member 640. The side extension cover portion 642 is bent so as to cover the first wiring member 20 and the second wiring member 30, and in this state, a binding member 650 such as an adhesive tape is wound around the outer periphery thereof.

According to the fifth modification, the first wiring member 20 and the second wiring member 30 can be covered and protected by the laterally extending portion of the sheet-like interval maintaining member 640. Since one side portion of the side extension cover portion 642 is connected to one side portion of the portion 640P, the side extension cover portion 642 can be easily wound around the first wiring member 20 and the second wiring member 30.

But in the said embodiment etc., it is made to cover the 1st wiring member 20 and the 2nd wiring member 30 with a member different from the sheet-like space | interval maintenance member 40, for example, a urethane sheet, a closely wound adhesive tape, etc. Also good.

16 and 17 are diagrams showing a wire harness 710 according to a seventh modification. In the wire harness 710, the first wiring member 20 is thicker than the second wiring member 30. Since the first wiring member 20 includes a power supply line, particularly a high-voltage power supply line, the first wiring member 20 is generally thicker than the second wiring member 30. The wire harness 710 includes a sheet-like interval maintaining member 640 corresponding to the sheet-like interval maintaining member 40. The sheet-like interval maintaining member 640 is formed with a plurality of first holding portions 42 and a plurality of second holding portions 46, but the plurality of first holding portions 42 is less than the plurality of second holding portions 46. Numbers are formed.

More specifically, during the production of the wire harness 710, the sheet-like interval maintaining member 740 is folded as follows. That is, the sheet-like interval maintaining member 740 is formed with folds 741a that are convex on one main surface side of the sheet-like interval maintaining member 740 and folds 741b1 and 741b2 that are convex on the other main surface side. Thus, the sheet-like interval maintaining member 740 is folded so as to be folded. The fold line 741a is disposed at a position where it overlaps substantially on the same line on the one main surface side of the sheet-like interval maintaining member 740. A part of the folds 741b1 and 741b2 is arranged at a position substantially overlapping on the other main surface side of the sheet-like interval maintaining member 740, and the other folds 741b2 are more than the folds 741b1a. Is also disposed at a position overlapping the substantially same line at a position away from the fold line 741a. Preferably, the folds 741b1 and 741b2 are provided with folds 741b2 at a constant period. And the sheet-like space | interval maintenance member 740 is folded in the state which the crease | fold 741b2 protruded outward rather than the crease | fold 741b1.

The first holding portion 42 is formed so as to pass through the portion between the fold line 741a and the fold line 741b2 with respect to the folded sheet-like interval maintaining member 740. For this reason, the 1st holding | maintenance part 42 is provided corresponding to the both sides of the crease | fold 741b2 in the extension direction of the sheet-like space | interval maintenance member 740. FIG.

The 2nd holding | maintenance part 46 is formed with respect to the folded sheet-like space | interval maintenance member 740 so that the part between the crease | fold 741a and the crease | fold 741b1 may be penetrated. For this reason, the 2nd holding | maintenance part 46 is provided corresponding to the both sides of the crease | fold 741a in the extension direction of the sheet-like space | interval maintenance member 740. FIG. Since the number of folds 741b2 is partial with respect to the number of folds 741b1 and 741b2, it is smaller than the number of folds 741a.

The first wiring member 20 is disposed through the plurality of first holding portions 42, and the second wiring member 30 is disposed through the plurality of second holding portions 46. In this state, when the sheet-like interval maintaining member 740 is extended, as shown in FIG. 17, the first wiring member 20 is held at a fixed position by a relatively small number of first holding portions 42, and the second wiring member 30. Is held at a fixed position by a relatively large number of second holding portions 46.

According to this modification, the relatively thick first wiring member 20 that is difficult to bend freely is held by a relatively small number of first holding portions 42. For this reason, the operation | work which arrange | positions the 1st wiring member 20 in the 1st holding | maintenance part 42 can be decreased, and the manufacture operation | work of the wire harness 710 can be made easy. Further, the second wiring member 30 that is relatively thin and easily bent can be held as constant as possible by being held by a relatively large number of the second holding portions 46. Thereby, the space | interval of the 1st wiring member 20 and the 2nd wiring member 30 can be maintained in the state opened more reliably.

Further, in the folded sheet-like interval maintaining member 740, by changing the folding position between the fold lines 741b1 and 741b2, the plurality of first holding portions 42 are linearly continued, and the plurality of second intervals are maintained. Since the holding portions 46 can be arranged continuously in a straight line, it is possible to easily form them and arrange the

wiring members

20 and 30.

In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts. For example, the first holding unit 42 and the second holding unit 46, and the first holding unit 342 and the second holding unit 346 may be combined. Further, a larger number (for example, four or more) of wiring members may be held by the sheet-like interval maintaining member.

Although the present invention has been described in detail as described above, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
