Problems to be Solved by the Invention

[0004] However, when the wiring jig member described in Patent Document 1 is mounted in a state where electric wires are arranged, it can become extremely large. For example, when the arrangement jig member described in Patent Document 1 is mounted on the door portion (lower part of the side glass) on the side surface of a vehicle in a state where electric wires are arranged, in reality, a wiring jig member of about the size of the door portion is required, resulting in an extremely large size.

[0005] The present disclosure provides a wiring jig member, a wire harness, and a method for mounting a wire harness on a vehicle that can be mounted on a vehicle together with electric wires while suppressing an increase in size.

Means for Solving the Problems

[0006] The wiring jig member according to this disclosure is a wiring jig member formed in a sheet shape by compressing fiber pieces, comprising a plurality of regularly arranged protrusions and a plate-like portion connecting the plurality of protrusions, wherein electric wires can be placed between the plurality of protrusions, and the plate-like portion has an easy-cut portion for easy cutting.

[Modes for carrying out the invention]

[0011] The present disclosure will be described below in accordance with preferred embodiments. However, the present disclosure is not limited to the embodiments shown below and may be modified as appropriate without departing from the spirit of the disclosure. Furthermore, in the embodiments shown below, some illustrations and descriptions of certain components are omitted. It goes without saying that, to the extent that the omitted technical details do not contradict the content described below, publicly known or well-known technologies are applied as appropriate.

[0012] FIG. 1 is a top view of a wiring jig member according to the present disclosure, FIG. 2 is a side view of the wiring jig member according to the present disclosure, and FIG. 3 is a partially enlarged view of the wiring jig member according to the present disclosure.

[0013] The wiring jig member 1 shown in FIGS. 1 and 2 is formed in a sheet shape by pressing fiber pieces. As the fiber pieces, pieces of paper made from fibers and pieces of fibers that can be raw materials for woolen fabrics such as animal hair can be used. Such a wiring jig member 1 is a so-called pulp mold or felt and has a predetermined rigidity.

[0014] The wiring jig member 1 according to the present embodiment includes a plurality of convex portions 10, a plate-like portion 20, and an easily cut-off portion 30. The plurality of convex portions 10 are regularly arranged in the sheet-shaped wiring jig member 1 and protrude in the sheet normal direction. In the example shown in FIGS. 1 and 2, the plurality of convex portions 10 have a frustum of a square pyramid shape. The frustum of a square pyramid forming each convex portion 10 is a frustum of a square pyramid, and each side of the square frustum is arranged parallel to the sides of the square frustum of the other convex portions 10. In particular, since the other convex portions 10 are arranged at 90-degree intervals around each convex portion 10, each convex portion 10 has a structure that is rotationally symmetric by 90 degrees in the top view shown in FIG. 1, which is preferable from the viewpoint of sandwiching the electric wire W described later.

[0015] The plate-like portion 20 is a portion connecting between the plurality of convex portions 10. The easily cut-off portion 30 is formed in the plate-like portion 20 and is for facilitating cutting of the wiring jig member 1 at the forming site. As shown in FIG. 3, the easily cut-off portion 30 is configured to have intermittently formed linear cuts. The cuts are formed so as to penetrate the front and back of the plate-like portion 20.

[0016] More specifically, the easy-cut portion 30 is composed of two first cuts 31 connected to the sheet edge of the wiring jig member 1, and a plurality of second cuts 32 intermittently provided between the two first cuts 31. Here, it is preferable that the length of the first cuts 31 is 1 mm or more greater than the thickness T of the plate-like portion 20 shown in Figure 2. Furthermore, it is preferable that the spacing and length of the second cuts 32 be determined such that the proportion of the second cuts 32 that occupies between the first cuts 31 is 50% or more. That is, it is preferable that the proportion of the length L shown in Figure 3 that occupies is 50% or more. Note that, as shown in Figure 1, two easy-cut portions 30 are formed on the wiring jig member 1, but there may be one or three or more.

[0017] Since the wiring jig member 1 described above has an easy-cut section 30, it can be cut at the easy-cut section 30, and the electric wire W (see Figure 5) can be placed in the cut state and each part can be mounted on the vehicle.

[0018] Figure 4 is a plan view showing a wire harness using the wiring jig member 1 shown in Figures 1 to 3. As shown in Figure 4, the wiring jig member 1 allows for the placement of electric wires W1 to W3 between the protrusions 10. Therefore, the wire harness WH can have the electric wires W1 to W3 placed on the wiring jig member 1 and is further divided into multiple (four) parts before being mounted on the vehicle door. Thus, the wiring jig member 1 according to this embodiment has a divided structure, which helps to keep it from becoming too large. The wire harness WH also has a first fixing part 2 and a second fixing part 3 for fixing the electric wires W1 to W3 placed between the protrusions 10.

[0019] First, in the divided first part (second jig member) P1 of the wiring jig member 1, the first electric wire W1 is arranged between the protrusions 10 in a bent state. Specifically, the first electric wire W1 is arranged in the first part P1 sandwiched between the six protrusions 10. Furthermore, the first part P1 has a second fixing part 3 at its sheet end (preferably both ends; the same applies hereinafter), and the first electric wire W1 is fixed by the second fixing part 3.

[0020] Similarly, in the first part P1, the second electric wire W2 is arranged between the protrusions 10 in a bent state. The second electric wire W2 is arranged in the first part P1 sandwiched between the six protrusions 10. Furthermore, the first part P1 has a second fixing part 3 at its sheet end, and the second electric wire W2 is fixed by the second fixing part 3.

[0021] In the second part (first jig member) P2, the first electric wire W1 is positioned in a straight line between the protrusions 10. The first electric wire W1 is positioned in the second part P2 sandwiched between the four protrusions 10. Furthermore, the second part P2 has a first fixing part 2 at its sheet end, and the first electric wire W1 is fixed by the first fixing part 2.

[0022] In the third part (first jig member, second jig member) P3, the second electric wire W2 is positioned in a straight line between the protrusions 10. The second electric wire W2 is positioned in the third part P3 sandwiched between the four protrusions 10. The third part P3 also has a first fixing part 2 at its sheet end, and the second electric wire W2 is fixed by the first fixing part 2.

[0023] Furthermore, in the third section P3, the third electric wire W3 is arranged in a straight line between the protrusions 10. The third electric wire W3 is positioned in the third section P3 sandwiched between the six protrusions 10. In addition, the third section P3 has a second fixing part 3 at its sheet end, and the third electric wire W3 is fixed by the second fixing part 3.

[0024] In the fourth part (first jig member) P4, the third electric wire W3 is positioned in a straight line between the protrusions 10. The third electric wire W3 is positioned in the fourth part P4 sandwiched between the four protrusions 10. Furthermore, the fourth part P4 has a first fixing part 2 at its sheet end, and the third electric wire W3 is fixed by the first fixing part 2.

[0025] Figure 5 is a schematic diagram showing an example of the first fixing part 2 shown in Figure 4. In the following explanation, if one of the first to third wires W1 to W3 is not specified, it will simply be referred to as wire W.

[0026] As shown in Figure 5, the first fixing part 2 secures the electric wire W to the second to fourth parts P2 to P4 (see Figure 4) with adhesive 2a. The fixing with adhesive 2a firmly secures the electric wire W to the first fixing part 2. On the other hand, the first fixing part 2 has temporary fixing marks TF where the electric wire W is temporarily fixed to the second to fourth parts P2 to P4 with staples 2b. As shown in Figure 5, the staples 2b are fixed to the plate-like part 20 in a state where they are floating above the diameter DI of the electric wire W. Therefore, when temporary fixing is performed only by staples 2b and fixing with adhesive 2a is not performed, the second to fourth parts P2 to P4 can move along the electric wire W. On the other hand, when fixing with adhesive 2a is performed, the second to fourth parts P2 to P4 cannot move along the electric wire W.

[0027] Figure 6 is a schematic diagram showing an example of the second fixing part 3 shown in Figure 4. As shown in Figure 6, the second fixing part 3 fixes the electric wire W to the first and third parts P1 and P3 (see Figure 4) with adhesive 2a. The fixing with adhesive 2a firmly secures the electric wire W to the second fixing part 3. Therefore, the first and third parts P1 and P3 become immovable along the electric wire W due to the fixing with adhesive 2a. The second fixing part 3 does not have any temporary fixing marks TF such as staples 2b.

[0028] Note that in Figure 5, temporary fixing is not limited to leaving the staple 2b floating; it may also be done by loosely tightening a cable tie, etc. Furthermore, the fixing shown in Figures 5 and 6 is not limited to adhesive 2a; it may also be done by using staple 2b without any floating, tape, or tightly tightened cable ties, etc.

[0029] Figure 7 is a schematic diagram showing another example of the first fixing part 2. In this example, temporary fixing is performed by a staple 2b in a floating state, similar to the example shown in Figure 5, and fixing may be performed by tightening the staple 2b so that it does not float. In this case, the staple 2b will have a separate bend 2c for temporary fixing and a bend 2d for fixed fixing, as shown in Figure 7, with the bend 2d becoming the temporary fixing mark TF.

[0030] Next, a method for mounting the wire harness WH according to this disclosure in a vehicle will be described. Figure 8 is a process diagram showing the method for mounting the wire harness WH in a vehicle, where (a) shows the first step, (b) shows the second and third steps, (c) shows the fourth step, and (d) shows the fifth step.

[0031] First, as shown in Figure 8(a), a wiring jig member 1 is prepared, and the electric wires W are placed between the protrusions 10 of the wiring jig member 1 (first step). At this time, each electric wire W is placed between the protrusions 10 while straddling the easy-cut portion 30. Here, the first and second electric wires W1 and W2 are placed in a bent state at the portion that will become the first portion P1 after cutting.

[0032] Next, as shown in Figure 8(b), the electric wire W is temporarily fixed to the second to fourth parts P2 to P4 (second step). Here, in the following drawings, the temporary fixing part where only temporary fixing has been performed is indicated by reference numeral 4. In this state, the second part P2 is slidable relative to the first electric wire W1. Also, the third part P3 becomes slidable relative to the second electric wire W2, and the fourth part P4 becomes slidable relative to the third electric wire W3.

[0033] Furthermore, the electric wires W are fixed to the first and third parts P1 and P3, forming the second fixing part 3 (third step). As a result, the first and second electric wires W1 and W2 are fixed immovably to the first part P1, and the third electric wire W3 is fixed immovably to the third part P3.

[0034] Next, the wiring jig member 1 is cut off by the easy-cut section 30 (fourth step). As a result, the wiring jig member 1 is divided into first to fourth parts P1 to P4, as shown in Figure 8(c).

[0035] Subsequently, as shown in Figure 8(d), the cut-off first part P1 is mounted on the vehicle. Furthermore, the second part P2 is moved along the first electric wire W1 and, after moving, is fixed to the first electric wire W1. As a result, the second part P2 is fixed immovably to the first electric wire W1, forming the first fixed part 2. Then, the second part P2 is mounted on the vehicle.

[0036] Furthermore, the third part P3 is moved along the second wire W2 and then fixed to the second wire W2. This fixes the third part P3 immovably to the second wire W2, forming the first fixing part 2. Then, the third part P3 is mounted on the vehicle.

[0037] Furthermore, the fourth part P4 is moved along the third wire W3 and then fixed to the third wire W3. This fixes the fourth part P4 immovably to the third wire W3, forming the first fixing part 2. Then, the fourth part P4 is mounted on the vehicle.

[0038] Based on the above, the vehicle mounting of the wire harness WH using the wiring jig member 1 according to this embodiment is completed. In addition, the second part P2 may be mounted on the vehicle with the temporary fixing part 4 still attached, and then the first fixing part 2 may be formed by filling the temporary fixing part 4 with adhesive 2a or the like. The same applies to the third and fourth parts P3 and P4. Furthermore, each part P1 to P4 of the wiring jig member 1 may be mounted on the vehicle by means such as clips or tape as appropriate.

[0039] Next, with reference to Figure 9, a preferred example of temporary fastening with staples 2b will be described. Figure 9 is a diagram showing the details of temporary fastening with staples 2b. Figure 10 is a diagram showing the details of staples 2b, where (a) shows the state before temporary fastening and (b) shows the state after temporary fastening.

[0040] In the example shown in Figure 9, two Yazaki Corporation CIUVS0.35 wires were used for the electric wire W. The wiring jig component 1 was made by compressing needle felt N-spec 10mm in a mold (the mold was made and manufactured by Taisei Corporation). The thickness T of the plate-like part 20 of the wiring jig component 1 (see Figure 2) is 5mm, and the staples 2b were attached using a Fujiwara Sangyo Co., Ltd. SMT-1 3-in-1 multi-tacker.

[0041] In the example shown in Figure 9, staples 2b were used with various values ​​for the first height H1 (which corresponds to the needle length shown in Figure 10), the needle width WI, and the thickness TH of the needle itself. Furthermore, the height of staples 2b after temporary fastening (second height H2) was adjusted, and staples 2b were also differentiated by whether or not a return C was provided.

[0042] First, the first height H1 of staple 2b was 6mm for items 1-8, 8mm for items 9-16, and 10mm for items 17-26. The width WI was 12mm for all staple 2b. The thickness TH was 0.7mm for items 1-4, 9-12, and 17-21, and 1.2mm for items 5-8, 13-16, and 22-26.

[0043] Furthermore, these staples 2b were fastened to the plate-shaped part 20 of the wiring jig member 1 by changing the presence or absence of the return C and the second height H2 using a tacker. The return C was absent in items 1-8, 11, 12, 15, 16, 21, and 26, and present in items 9, 10, 13, 14, 17-20, and 22-25. The second height H2 was 0 mm in items 1, 5, 9, 13, 17, and 22, 1 mm in items 2, 6, 10, 14, 18, and 23, and 2 mm in items 3, 7, 11, 15, 19, and 24. The second height H2 was 3 mm in items 4, 8, 12, 16, 20, and 25, and 4 mm in items 21 and 26.

[0044] Then, we performed evaluations of the sliding of the wire W, damage to the wire W, and the release of staple 2b for these components. For the sliding of the wire W, "◎" was given if the worker could easily slide the wire W while grasping the wiring jig member 1, and "×" if sliding was difficult. For the damage to the wire W, "◎" was given if no deformation of the wire W or damage to the insulation occurred due to sliding after temporary fastening, "〇" was given if deformation or damage occurred but was within an acceptable range, and "×" was given if unacceptable deformation or damage occurred. For the release of staple 2b, after temporary fastening, "◎" was given if the wire W was pulled vertically (normal to the wiring jig member 1) with a force of 0.2N and staple 2b did not move more than 1mm, and "〇" was given if it moved more than 1mm but did not come off. "×" was given if staple 2b came off.

[0045] As a result, items 1, 5, 9, 13, 17, and 22, where the second height H2 is 0 mm, received a "×" in both the wire W sliding evaluation and the wire W damage evaluation. Therefore, it was found that when using staple 2b during temporary fixing, a gap is necessary.

[0046] Furthermore, some of the items with a second height H2 of 1 mm (items 2 and 6) were slightly scratched during sliding, resulting in a "○" rating in the damage evaluation to the electrical wire W.

[0047] Furthermore, among items 1-8 where the first height H1 is short at 6mm, items 2-4, 7, and 8, where the second height H2 is high, indicate that the staples 2b are not deeply embedded in the wiring jig member 1, and no return C is formed. Therefore, the staple 2b release evaluation for these items was "○". Similarly, among items 9-16 where the first height H1 is 8mm, items 12 and 16, where the second height H2 is high, also received a "○" for staple 2b release evaluation for the same reason. From the above, it was found that it is preferable for the value obtained by subtracting the second height H2 from the first height H1 to be 6mm or more. In particular, it was found that a return C is not necessary if this value is 6mm or more. Furthermore, all items with a return C received a "◎" for staple 2b release evaluation. Therefore, although there is an exception in item 6, it was found that if this value is less than 6mm, the staple 2b only needs to have a return C.

[0048] Furthermore, it was found that changing the thickness (TH) had little effect on the evaluation.

[0049] Furthermore, it is preferable that the multiple protrusions 10 of the wiring jig member 1 can hold the electric wire W to some extent by clamping, even without the fixing parts 2 and 3. Moreover, it is preferable that the holding force of the electric wire W by clamping of the protrusions 10 is not too high from the viewpoint of sliding.

[0050] Figure 11 is a chart showing the holding force when the conditions of the protrusion 10 and the wire bundle are changed. Figure 12 is a configuration diagram showing the wiring arrangement in the wiring jig member 1, where (a) is a plan view and (b) is a side view.

[0051] In the example shown in Figure 11, the wire bundle was formed by roughly winding a predetermined number of Yazaki Corporation's CIUVS0.35 wires with 0.09 mm thick polyvinyl chloride tape. The wiring jig member 1 was created by compressing needle felt N-spec 10 mm in a mold (the mold was made and manufactured by Taisei Corporation). Various protrusions 10 were formed by heating and pressing rods of predetermined diameters and shapes.

[0052] In the example shown in Figure 11, the wiring jig member 1 used had different protrusion distances CL, protrusion diameters CD, protrusion depths DE, and thicknesses T as shown in Figure 12(b). Furthermore, the wiring jig member 1 used both cylindrical and truncated square pyramidal shapes for the protrusions 10. Note that when the protrusion 10 is truncated square pyramidal, the protrusion diameter CD is the length of one side at the point where the truncated square pyramid touches the plate-like portion 20.

[0053] First, the shape of the protrusion 10 was cylindrical for items 27-31 and 37-65, and truncated square pyramidal for items 32-36. The distance CL between the protrusions was 10 mm for items 27-36 and 52-65, and 5 mm for items 37-51.

[0054] Furthermore, the diameter CD of the protrusion was 14 mm in all cases. The depth DE of the protrusion was 16 mm for items 27-41 and 52-65, 5 mm for items 42-46, and 8 mm for items 47-51. The thickness T was 8 mm for items 27-61 and 10 mm for items 62-65.

[0055] The wire bundles in items 27-51 and 62-65 consisted of 5 wires with a diameter of 3-5 mm, items 52-56 consisted of 40 wires with a diameter of 7-11 mm, and items 57-61 consisted of 50 wires with a diameter of 8-12 mm.

[0056] These wire bundles were arranged to form one of the paths 1 to 5 shown in Figure 12(a). Wire bundles numbered 27, 32, 37, 42, 47, 52, 57, and 62 formed path 1, and wire bundles numbered 28, 33, 38, 43, 48, 53, 58, and 63 formed path 2. Wire bundles numbered 29, 34, 39, 44, 49, 54, 59, and 64 formed path 3, and wire bundles numbered 30, 35, 40, 45, 50, 55, and 60 formed path 4. Wire bundles numbered 31, 36, 41, 46, 51, 56, 61, and 65 formed path 5.

[0057] For the wiring jig members 1 and wire bundles described in items 27 to 65 above, we measured the pull-out load and evaluated the holding force. The pull-out load was measured when the wire bundle was pulled out without any gaps in the direction normal to the wiring jig member 1. The holding force was measured by turning the wire bundle upside down while it was placed on the wiring jig member 1, and evaluating whether the wire bundle did not fall as "strong" and whether it fell as "weak".

[0058] First, items 27-29 had pull-out loads of 0.22N, 0.17N, and 0.21N respectively, indicating a "strong" holding force. Next, items 30 and 31 had pull-out loads of 0.10N and 0.07N respectively, indicating a "weak" holding force. Furthermore, items 32-34 had pull-out loads of 0.28N, 0.16N, and 0.20N respectively, indicating a "strong" holding force. Items 35 and 36 had pull-out loads of 0.11N and 0.05N respectively, indicating a "weak" holding force.

[0059] For items 37-43, the pull-out loads were 0.58N, 0.56N, 0.65N, 0.53N, 0.30N, 0.18N, and 0.17N respectively, and the holding force was "strong". For items 44-46, the pull-out loads were 0.09N, 0.05N, and 0.06N respectively, and the holding force was "weak".

[0060] For items 47-55, the pull-out loads were 0.37N, 0.34N, 0.39N, 0.25N, 0.16N, 3.10N, 2.70N, 3.10N, and 2.60N respectively, and the holding force was "strong". For item 56, the pull-out load was 0.46N and the holding force was "weak".

[0061] For items 57-60 and 62-64, the pull-out loads were 4.40N, 3.58N, 4.01N, 4.12N, 0.24N, 0.22N, and 0.22N respectively, indicating a "strong" holding force. For items 61 and 65, the pull-out loads were 0.76N and 0.09N respectively, indicating a "weak" holding force.

[0062] As described above, it was found that by adopting the same configuration as above to achieve a "strong" holding force, it is possible to minimize the number of, for example, the first fixing part 2 and the second fixing part 3. Specifically, it was found that to achieve a "strong" holding force, the value obtained by dividing the pull-out load by the number of parts should be 0.032 N / part or more.

[0063] Furthermore, when sliding operations were performed on items 27 to 60, it was found that the pull-out load was preferably 0.50 N or less in the bent state (paths 1 to 4) and preferably 3.00 N or less in the straight state (path 5). A force greater than the pull-out load is required during the sliding operation. Therefore, it was found that the sliding operation efficiency can be improved by lowering the pull-out load.

[0064] Figure 13 is a chart showing the pull-out load and holding force based on the distance CL between the protrusions, the number of protrusions that are clamped, and whether the electric wire W is straight or bent. Figure 14 is a plan view showing the arrangement of the electric wire W shown in Figure 13, where (a) shows the first arrangement, (b) shows the second arrangement, (c) shows the third arrangement, (d) shows the fourth arrangement, (e) shows the fifth arrangement, and (f) shows the sixth arrangement.

[0065] In the example shown in Figure 13, the wire bundle used consisted of five Yazaki Corporation CIUVS0.35 wires roughly wrapped with 0.09 mm thick polyvinyl chloride tape, with a wire bundle diameter of 3 to 5 mm. The wiring jig component 1 was created by compressing needle felt N-spec 10 mm in a mold (the mold was created and manufactured by Taisei Corporation). The protrusion 10 was formed by heating and pressing a rod with a round tip of a predetermined diameter.

[0066] In the example shown in Figure 13, the distance CL between the protrusions of the wiring jig member 1 was varied. The diameter CD of the protrusions was standardized to 14 mm, and the shape of the protrusions 10 was standardized to a cylindrical shape. The depth DE of the protrusions was also standardized to 16 mm.

[0067] For items 66-68, the number of linearly clamping protrusions was set to "2" as shown in Figure 14(a). For items 69-71, the number of linearly clamping protrusions was set to "4" as shown in Figure 14(b). For items 72-74, the number of linearly clamping protrusions was set to "6" as shown in Figure 14(c).

[0068] For items 75-77, the wire bundles were arranged in a bent shape as shown in Figure 14(d), and the number of clamping protrusions was set to "3". For items 78-80, the wire bundles were arranged in a bent shape as shown in Figure 14(e), and the number of clamping protrusions was set to "5". For items 81-83, the wire bundles were arranged in a bent shape as shown in Figure 14(f), and the number of clamping protrusions was set to "7".

[0069] For the wiring jig components 1 and wire bundles described in items 66 to 83 above, the pull-out load was measured and the holding force was evaluated. The pull-out load and holding force evaluation were the same as described above.

[0070] First, items 66, 67, 69, and 72 had pull-out loads of 0.04N, 0.09N, 0.06N, and 0.06N respectively, indicating a "weak" holding force. On the other hand, items 68, 70, 71, 73, and 74 had pull-out loads of 0.14N, 0.21N, 0.45N, 0.24N, and 0.60N respectively, indicating a "strong" holding force.

[0071] Furthermore, for items 75, 76, and 78, the pull-out loads were immeasurable, 0.07N, and 0.13N respectively, indicating a "weak" holding force. For items 77, 79-83, the pull-out loads were 0.65N, 0.39N, 0.71N, 0.23N, 0.41N, and 0.81N respectively, indicating a "strong" holding force.

[0072] In the examples from items 66 to 83, it was found that to achieve a "strong" holding force, the value obtained by dividing the pull-out load by the number of pieces should be 0.032 N / piece or more. Furthermore, it was found that for the subsequent sliding operation, it is preferable that the pull-out load be 3.00 N or less in items 66 to 74, and 0.50 N or less in items 75 to 84.

[0073] In this way, the wiring jig member 1 according to this embodiment allows for the placement of electric wires W between the multiple protrusions 10, and the plate-like portion 20 has an easy-cut portion 30 for easy cutting. Therefore, the wiring jig member 1 is mounted on the vehicle side so that it is cut as appropriate by the easy-cut portion 30 and the various portions P1 to P4 are scattered. As a result, the wiring jig member 1 does not need to be the size corresponding to the entire area of ​​the vehicle mounting location. Thus, it is possible to provide a wiring jig member 1 that can be mounted on a vehicle together with electric wires W while keeping the size down.

[0074] Furthermore, the wire harness WH according to this embodiment has a first fixing portion 2 with a temporary fixing mark TF on one side that has been cut off at the easy-cut portion 30, and a second fixing portion 3 on the other side that does not have a temporary fixing mark TF. Therefore, the electric wire W was initially temporarily fixed on one side, and it can be said that one side was movable along the electric wire W. In this case, with the electric wire W fixed to the other side, the parts P1 to P4 can be mounted in a scattered manner by moving one side along the electric wire W to a location corresponding to the vehicle mounting state. Thus, it is possible to provide a wire harness WH using a wiring jig member 1 that can be mounted on a vehicle together with the electric wire W while suppressing the increase in size.

[0075] Furthermore, in the second to fourth sections P2 to P4, the electric wire W, which is fixed by the first fixing section 2, is arranged in a straight line. Therefore, compared to cases where there are bends, the second to fourth sections P2 to P4 can move more smoothly along the electric wire W when temporarily fixed. Consequently, the ease of wiring can be improved.

[0076] Furthermore, the number of protrusions 10 that grip the electric wire W is fewer in the second to fourth sections P2 to P4, which have temporary fixing marks TF, than in the first and third sections P1 and P3, which do not have temporary fixing marks TF. As a result, the second to fourth sections P2 to P4 have relatively few points where they grip the electric wire W, making it easier to move smoothly along the electric wire W when it is in a temporarily fixed state. Therefore, the ease of wiring can be improved.

[0077] Furthermore, according to the vehicle mounting method for the wire harness WH of this embodiment, the electric wire W is temporarily fixed to the second to fourth parts P2 to P4 and then fixed to the first and third parts P1 and P3. Next, the easily cut portion 30 is cut off, and the second to fourth parts P2 to P4 are moved along the electric wire W and then fixed immovably to the electric wire W before being mounted on the vehicle. As a result, the wiring jig member 1 does not need to be the size corresponding to the entire area of ​​the vehicle mounting location, and the cut second to fourth parts P2 to P4 are moved along the electric wire W to a location corresponding to the vehicle mounting state, so that each part P1 to P4 is mounted in a scattered state. Therefore, it is possible to provide a vehicle mounting method for a wire harness WH using a wiring jig member 1 that can be mounted on a vehicle together with the electric wire W while suppressing the increase in size.
