[0053] Hereinafter, the implementation manners and modification examples related to the present invention will be described in detail based on the drawings. In addition, the present invention is not limited to the following implementation manners and modification examples. Further, among the components in the following implementation manners and modification examples, there are components that can be easily replaced by those skilled in the art, or components that are substantially the same.

[0054] In addition, the same components are included in the implementation manners and modification examples disclosed below. Therefore, hereinafter, the same reference numerals will be assigned to these same components, and repeated descriptions will be omitted. In addition, in this specification, ordinal numbers are only used to distinguish elements, components, parts, positions, directions, etc., and do not represent order or priority.

[0055] [Implementation manner]

[0056] Figure 1 is a perspective view of a vehicle 100 to which the wire harness assembly 1 according to the implementation manner is applied, Figure 2 is a cross-sectional view of the wire harness assembly 1. Figure 1 , Figure 2 The wire harness assembly 1 of the present implementation manner shown in is applicable to vehicles 100 such as automobiles, and connects between various devices mounted on the vehicle 100 for power supply and signal communication. The wire harness assembly 1 of the present implementation manner includes, for example: a wire harness WH; a rigid member 10A having a predetermined rigidity and provided with a laying space portion 12 inside for laying the wire harness WH; and a slit 20 provided on the outer wall 11 of the rigid member 10A and capable of inserting the wire harness WH into the laying space portion 12 from the outside. The wire harness WH is configured to include a wire bundle 30 formed by bundling a plurality of conductive wires W (refer to Figure 5 ). In addition, the wire harness assembly 1 may also be configured to include connectors, bellows, grommets, fixing members, etc. in addition to this.

[0057] Here, in the present implementation manner, the rigid member 10A is constituted by a body member 10 that constitutes the skeleton of the vehicle 100. The body member 10 is, for example, a tubular sill that constitutes the lower side beam 3 of the vehicle 100, and is mounted on the vehicle 100 in a state where both end portions in the axial direction X of the laying space portion 12 are closed. Moreover, in the present implementation manner, the wire harness WH is inserted and laid in the laying space portion 12 that is the internal space portion of the body member 10 via the slit 20. Thus, for example, compared with the case of laying the wire harness WH between the body member 10 and the fender 4, the position of the fender 4 can be set lower, and further, the opening area of the boarding and alighting opening of the vehicle 100 can be enlarged to enable passengers to get on and off more smoothly. The slit 20 is provided on the vehicle 100, for example, in a state of being covered by the fender 4.

[0058] In addition, in the following description, among the first direction, the second direction, and the third direction that intersect each other, the first direction is referred to as the "axial direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the axial direction X, the width direction Y, and the height direction Z are substantially orthogonal to each other. The axial direction X typically corresponds to the extending direction of the wire harness WH, the length direction of the vehicle body component 10 (rigid component 10A), etc., and extends along the longitudinal direction of the vehicle. The width direction Y typically corresponds to the width direction (left - right direction) of the vehicle body component 10 (rigid component 10A), etc., and extends along the width direction of the vehicle. The height direction Z typically corresponds to the height direction (up - down direction) of the vehicle body component 10 (rigid component 10A), etc., and extends along the up - down direction of the vehicle. In addition, each direction used in the following description is described as the direction in the state where the wire harness assembly 1 is assembled to the vehicle 100 unless otherwise specified. In addition, in Figure 2 and Figure 8 etc., for convenience, the illustration of the multiple wires W that constitute the wire harness 30 is simplified.

[0059] Figure 3 is a perspective view of the vehicle body component 10 of the wire harness assembly 1, Figure 4 is a plan view near the wide portion 22 of the slit 20 of the wire harness assembly 1. As Figure 3 , Figure 4 shown, the vehicle body component 10 is made of, for example, an extruded material of a metallic material, and has an outer wall 11 with a rectangular tubular cross - sectional shape that intersects the axial direction X. The outer wall 11 is a structure for partitioning the above - mentioned laying space portion 12 that is the internal space portion of the vehicle body component 10. The laying space portion 12 is a space portion for inserting and laying the wire harness 30 of the wire harness WH. The outer wall 11 is configured to include, for example, an upper wall 11a, a lower wall 11b, and a pair of side walls 11c, 11d.

[0060] Both the upper wall 11a and the lower wall 11b extend along a direction orthogonal to the height direction Z, and are arranged parallel to each other with a space therebetween in the height direction Z. The upper wall 11a constitutes the upper end portion of the vehicle body component 10, and the lower wall 11b constitutes the lower end portion of the vehicle body component 10. The upper wall 11a faces the interior space of the vehicle 100, and the lower wall 11b faces the floor of the vehicle 100. The upper wall 11a and the lower wall 11b are formed in a flat plate shape that extends horizontally along the axial direction X.

[0061] A pair of side walls 11c and 11d both extend along a direction orthogonal to the width direction Y, and are arranged in parallel with a gap therebetween in the width direction Y. The side wall 11c is arranged between one end portions in the width direction Y of the upper wall 11a and the lower wall 11b, and constitutes the right end portion of the vehicle body component 10. The side wall 11d is arranged between the other end portions in the width direction Y of the upper wall 11a and the lower wall 11b, and constitutes the left end portion of the vehicle body component 10. The side wall 11c faces the interior space of the vehicle 100, and the side wall 11d faces the frame of the vehicle 100 or the like. The pair of side walls 11c and 11d are formed in a flat plate shape that extends horizontally along the axial direction X.

[0062] Here, in the present embodiment, in the upper wall 11a, the lower wall 11b, and the pair of side walls 11c and 11d that constitute the outer wall 11, for example, a slit 20 extending along the axial direction X is provided in the upper wall 11a facing the interior space of the vehicle. The upper wall 11a is a partition wall that separates the layout space portion 12 of the vehicle body component 10 from the interior space of the vehicle. The layout space portion 12 is the internal space portion of the vehicle body component 10, and the interior space of the vehicle is the external space portion of the vehicle body component 10. The slit 20 is a through hole that penetrates the upper wall 11a along the height direction Z, and communicates the layout space portion 12 of the vehicle body component 10 with the interior space of the vehicle. Thus, the wire harness 30 of the wire harness WH can be inserted into the layout space portion 12 from the interior space side of the vehicle via the slit 20. In the present embodiment, the upper wall 11a is an example of the first wall portion.

[0063] In addition, the slit 20 is configured to include, for example, a narrow-width portion 21 and a wide-width portion 22. The narrow-width portion 21 has an opening width d1 formed to be narrower than the outer diameter d of the wire harness 30 (refer to Figure 2 ), and the wide-width portion 22 has an opening width d2 formed to be wider than the outer diameter d of the wire harness 30. The opening width d1 is the opening width of the narrow-width portion 21 along the width direction Y, and the opening width d2 is the opening width of the wide-width portion 22 along the width direction Y. In the present embodiment, the narrow-width portion 21 is provided between one end portion and the other end portion of the upper wall 11a in the axial direction X, and penetrates the upper wall 11a along the axial direction X. The wide-width portion 22 is partially provided on the other end portion side of the narrow-width portion 21 in the axial direction X and communicates with the narrow-width portion 21. The wide-width portion 22 functions as an entrance opening when inserting a jig 5 (refer to Figures 8 - 10 ) described later into the slit 20.

[0064] In addition, in the present embodiment, the opening width d1 of the narrow-width portion 21 is formed to be at least wider than the outer diameter d3 of one wire W having the largest outer diameter among the plurality of wires W constituting the wire harness 30 (refer to Figure 6 ) and the plate thickness d4 of the pair of side walls 5b of the jig 5 for inserting the wire harness 30 into the layout space portion 12 via the slit 20 (refer to Figure 9) total width. Specifically, in the present embodiment, the plurality of electric wires W are configured to have the same outer diameter as each other, and the opening width d1 of the narrow portion 21 is set to the total width of the outer diameters d3 of about two or three of the plurality of electric wires W. In addition, in the present embodiment, an example is given in which the plurality of electric wires W are each configured to have the same outer diameter as each other, but it is not limited to this example. For example, at least one of the plurality of electric wires W may be configured to have an outer diameter different from that of the other electric wires W.

[0065] In addition, in the present embodiment, an example is given in which the slit 20 is configured to include the narrow portion 21 and the wide portion 22, but it is not limited to this example. For example, the wide portion 22 may not be provided and the slit 20 may be composed only of the narrow portion 21. In addition, in the present embodiment, an example is given in which the slit 20 is provided between one end and the other end in the axial direction X of the upper wall 11a, but it is not limited to this example. For example, it may be locally provided at an intermediate position between one end and the other end in the axial direction X of the upper wall 11a. Further, in the present embodiment, an example is given in which the body member 10 has a rectangular tubular cross-sectional shape and the laying space portion 12 is configured as an enclosed internal space portion, but it is not limited to this example. For example, the body member 10 may be formed to have a substantially U-shaped cross-sectional shape, and the laying space portion 12 may not be enclosed. Further, in this case, the laying space portion 12 may be enclosed by another member different from the body member 10.

[0066] Figure 5 is a perspective view of the wire harness WH of the wire harness assembly 1, Figure 6 is a cross-sectional view of the bundling posture maintaining portion 31 of the wire harness WH, Figure 7 is a cross-sectional view of the bundling posture variable portion 32 of the wire harness WH. As Figures 5 - 7 shown, the wire harness WH has, for example, a wire bundle 30 formed by bundling a plurality of electric wires W. The electric wire W is configured to include a core wire and an insulating coating portion that covers the core wire. The electric wires W are each formed to extend linearly along the axial direction X and extend with substantially the same diameter in the axial direction X (extension direction). In addition, for example, the cross-sectional shape of the core wire of the electric wire W (the cross-sectional shape of the cross-section intersecting the axial direction X) is formed to be substantially circular, and the cross-sectional shape of the insulating coating portion is formed to be substantially annular, and the overall cross-sectional shape is formed to be substantially circular.

[0067] In addition, the wire harness 30 is configured to include, for example, a pair of bundling posture maintaining portions 31 and a bundling posture variable portion 32. The pair of bundling posture maintaining portions 31 are located at both end portions 30a in the axial direction X of the wire harness 30, and are portions bundled in a manner to maintain the bundling posture. In the present embodiment, first bundling members 40 for bundling a plurality of wires W are respectively provided at the pair of bundling posture maintaining portions 31. The pair of first bundling members 40 may be, for example, bundling members such as bundling tapes, or tape members such as tapes, or other members. The first bundling member 40 bundles the plurality of wires W in a manner to maintain the bundling posture of the wire harness 30, in other words, the cross-sectional shape (refer to Figure 6 ) that intersects the axial direction X of the wire harness 30.

[0068] The first bundling member 40, for example, surrounds the periphery of the plurality of wires W at the same position in the axial direction X of the wire harness 30. That is, the first bundling member 40 is wound around the plurality of wires W such that the portion located inside and the portion overlapping on the outside in the overlapping portion are at the same position in the axial direction X. A plurality of wires W are exposed in the interval between one of the pair of first bundling members 40 and the other. It should be noted that in the present embodiment, a case where the first bundling member 40 is formed by circumferentially winding around the periphery of the plurality of wires W at the same position in the axial direction X of the wire harness 30 is exemplified, but it is not limited to this example. For example, it may also be formed by helically winding around the periphery of the plurality of wires W at different positions in the axial direction X of the wire harness 30.

[0069] The bundling posture variable portion 32 is a portion of the wire harness 30 that is located between the pair of bundling posture maintaining portions 31 in the axial direction X and allows the bundling posture to be variable. In the present embodiment, a second bundling member 50 that loosely bundles the plurality of wires W compared to the first bundling member 40 is provided at the bundling posture variable portion 32. The second bundling member 50 is provided, for example, at the central portion 30b in the axial direction X of the wire harness 30. The second bundling member 50 may be, for example, a bundling member such as a bundling tape, or a tape member such as a tape, or other members. The second bundling member 50 bundles the plurality of wires W in a manner such that the bundling posture of the wire harness 30, in other words, the cross-sectional shape (refer to Figure 7 ) that intersects the axial direction X of the wire harness 30 is variable.

[0070] The second bundling member 50, for example, has a diameter larger than the outer diameter d of the wire harness 30 (refer to Figure 2) The inner diameter of the large diameter is configured to allow displacement of the wire harness 30 in the radial direction. That is, the second bundling member 50 is wound around the plurality of wires W in such a manner that the plurality of wires W can move relative to each other and disperse. The second bundling member 50 can be formed, for example, by winding around the periphery of the plurality of wires W at the same position in the axial direction X of the wire harness 30, or can be formed by helically winding around the periphery of the plurality of wires W at different positions in the axial direction X of the wire harness 30. A plurality of wires W are exposed in the section of the wire harness 30 between the second bundling member 50 and the pair of first bundling members 40 described above.

[0071] In addition, in the present embodiment, an example is given in which the bundling posture variable part 32 bundles the plurality of wires W by the second bundling member 50, but it is not limited to this example. For example, the second bundling member 50 may not be provided and the plurality of wires W may not be bundled. That is, the bundling posture variable part 32 also includes a form in which bundling members such as the second bundling member 50 do not exist. The bundling posture variable part 32 is also referred to as a cross-sectional shape variable part, etc., and the bundling posture maintaining part 31 is also referred to as a cross-sectional shape maintaining part, etc.

[0072] Figure 8 is an exploded perspective view of the wire harness assembly 1, Figure 9 is a perspective view of the jig 5, Figure 10 is a side view of the jig 5. As Figures 8 - 10 shown, the jig 5 is used, for example, when inserting the wire harness 30 of the wire harness WH into the laying space portion 12 of the vehicle body member 10 through the slit 20. The jig 5 is formed of a flexible flexural material such as synthetic resin, and is configured to include a bottom wall 5a, a pair of side walls 5b, a pair of flange walls 5c, a first cutting portion 5f, and a second cutting portion 5e.

[0073] The pair of side walls 5b are portions of the jig 5 that hold the wire harness 30 from both sides in the width direction Y. The pair of side walls 5b both extend in a direction orthogonal to the width direction Y, and are provided parallel to each other at intervals in the width direction Y. One of the pair of side walls 5b constitutes the right end portion of the jig 5, and the other of the pair of side walls 5b constitutes the left end portion of the jig 5. The pair of side walls 5b are formed in a flat plate shape that extends horizontally along the axial direction X.

[0074] The bottom wall 5a is a portion that extends in an arc shape along the outer peripheral surface of the wire harness 30 and connects one end portion 5g in the height direction Z of the pair of side walls 5b to each other. The bottom wall 5a has a substantially U-shaped cross section that opens toward the other side in the height direction Z. The bottom wall 5a constitutes the upper end portion of the jig 5 and holds the wire harness 30 from one side in the height direction Z. In the present embodiment, the bottom wall 5a and the pair of side walls 5b are formed in a tapered shape that is inclined such that the other end portion 5h of the bottom wall 5a in the height direction Z gradually approaches the pair of side walls 5b as it goes from the one end portion 5j side to the other end portion 5k side in the axial direction X. Thereby, the insertability of the wire harness 30 with respect to the slit 20 is improved. That is, the bottom wall 5a functions as a guide when the wire harness 30 is inserted into the slit 20.

[0075] A pair of flange walls 5c are provided at the other end portion 5h in the height direction Z of the pair of side walls 5b, and are portions that protrude from the other end portion 5h toward the separated side along the width direction Y. The pair of flange walls 5c are slidably engaged with the inner surface 11a1 (refer to Figure 12 ) on the side of the layout space portion 12 of the upper wall 11a at the peripheral portion of the slit 20. The pair of flange walls 5c extend in parallel with the upper wall 11a. The protruding amount of the pair of flange walls 5c along the width direction Y is appropriately set according to the opening widths d1, d2, etc. of the slit 20.

[0076] The first cutting portion 5f is provided at the other end portion 5k side in the axial direction X of the bottom wall 5a and the pair of side walls 5b, and is a portion that extends along the height direction Z over the bottom wall 5a and the other end portion 5h of the pair of side walls 5b when viewed from the width direction Y (refer to Figure 10 ). The first cutting portion 5f has a flat end face facing the other side in the axial direction X. The first cutting portion 5f is formed, for example, by cutting the other end portion 5k of the bottom wall 5a and the pair of side walls 5b along the height direction Z. The first cutting portion 5f is perpendicular to the pair of flange walls 5c. The first cutting portion 5f functions, for example, as a portion that suppresses hooking when the jig 5 is inserted into the slit 20.

[0077] The second cutting portion 5e is provided at the one end portion 5j side in the axial direction X of the bottom wall 5a and the pair of side walls 5b, and is a portion that extends along the height direction Z over the bottom wall 5a and the other end portion 5h of the pair of side walls 5b when viewed from the width direction Y (refer to Figure 10) The portion that extends along the inclined direction between the height direction Z and the axial direction X across one end portion 5j of the bottom wall 5a and a pair of side walls 5b. The second cutting portion 5e is provided at the corner portion 5n where the bottom wall 5a intersects with the pair of side walls 5b on the one end portion 5j side in the axial direction X. The second cutting portion 5e has a flat end face facing the one side in the axial direction X and the one side in the height direction Z. The second cutting portion 5e is formed, for example, by cutting the corner portion 5n of the bottom wall 5a and the pair of side walls 5b along the inclined direction between the height direction Z and the axial direction X. The second cutting portion 5e is inclined with respect to the pair of flange walls 5c, the first cutting portion 5f, etc. The second cutting portion 5e functions, for example, as a portion that suppresses hooking when the jig 5 is inserted into the slit 20.

[0078] Next, an example of a manufacturing method of the wire harness assembly 1 having the above structure will be described. Figure 11 It is a flowchart of the manufacturing method of the wire harness assembly 1, Figure 12 It is a perspective view of the wire harness assembly 1 and is a view showing the first step S1, Figure 13 It is a perspective view of the wire harness assembly 1 and is a view showing the second step S2, Figure 14 It is a perspective view of the wire harness assembly 1 and is a view showing the third step S3, Figure 15 It is a perspective view of the wire harness assembly 1 and is a view showing the fourth step S4.

[0079] First, in the process of the first step S1, as Figure 11 、 Figure 12 shown, the wire harness 30 formed by bundling a plurality of electric wires W is held by the jig 5. In this case, the pair of side walls 5b of the jig 5 hold the above-described bundling posture variable portion 32 of the wire harness 30 from both sides in the width direction Y, and the bundling posture variable portion 32 is deformed or displaced so as to be in a vertically long state along the height direction Z. Further, the jig 5 is inclined so that the bottom wall 5a of the jig 5 is parallel to the wire harness 30 (axial direction X). In this case, the jig 5 is inclined such that the one end portion 5j in the axial direction X is closer to the slit 20 located on the other side in the height direction Z than the other end portion 5k.

[0080] Next, in the process of the second step S2, as Figure 11 、 Figure 13As shown, the jig 5 is inserted into the slit 20 provided in the outer wall 11 of the vehicle body part 10 (rigid part 10A). In this case, the jig 5 is inserted into, for example, the wide part 22 of the slit 20 and is inserted obliquely with respect to the wide part 22. At this time, in the present embodiment, since the above-described second cutting part 5e is provided at one end part 5j in the axial direction X of the jig 5, the end part 5j in the axial direction X of the jig 5 is prevented from hooking on the edge part of the wide part 22 by this second cutting part 5e. Then, the jig 5 inserted obliquely with respect to the wide part 22 is pressed into one side in the axial direction X so that the pair of flange walls 5c of the jig 5 are restored to a posture parallel to the upper wall 11a. At this time, in the present embodiment, since the above-described first cutting part 5f is provided at the other end part 5k in the axial direction X of the jig 5, the other end part 5k in the axial direction X of the jig 5 is prevented from hooking on the edge part of the wide part 22 by this first cutting part 5f.

[0081] Next, in the process of the third step S3, as Figure 11 , Figure 14 shown, by sliding the jig 5 along the narrow part 21 of the slit 20, the wire harness 30 is deformed or displaced so as to have a width narrower than the opening width d1 of the slit 20, and the wire harness 30 is inserted into the laying space part 12 of the vehicle body part 10 from the outside. In this case, the pair of flange walls 5c of the jig 5 are slidably engaged with the peripheral part of the slit 20 on the inner surface 11a1 of the upper wall 11a. The bundling posture variable part 32 of the wire harness 30 is guided by the bottom wall 5a of the jig 5 toward the slit 20, and as the jig 5 slides in one side in the axial direction X with respect to the upper wall 11a, the bundling posture variable part 32 falls from the opening 5d between the pair of side walls 5b through the slit 20 into the laying space part 12.

[0082] Then, in the process of the fourth step S4, as Figure 11 , Figure 15 shown, the jig 5 is removed with respect to the slit 20. In this case, the jig 5 is pulled out obliquely with respect to the narrow part 21 of the slit 20. In a state where the wire harness 30 is assembled to the vehicle body part 10, the bundling posture variable part 32 at the central part 30b in the axial direction X is disposed in the laying space part 12, and the pair of bundling posture maintaining parts 31 at the both end parts 30a in the axial direction X are led out to the outside of the vehicle body part 10 through the slit 20. Through the first step S1 to the fourth step S4 in this way, the wire harness 30 of the wire harness WH can be assembled to the laying space part 12 of the vehicle body part 10 to manufacture the wire harness assembly 1. In addition, the jig 5 is not limited to Figure 9 , Figure 12 being used in the orientation along the vertical direction (height direction Z) as shown, for example, it can also be used in an orientation laid down in the horizontal direction (width direction Y or axial direction X).

[0083] As described above, in the wiring harness assembly 1 and the manufacturing method of the wiring harness assembly 1 according to the present embodiment, a slit 20 is provided on the outer wall 11 of the rigid member 10A. The slit 20 extends along the axial direction X and enables the wire harness 30 to be inserted into the laying space portion 12 from the outside. According to this structure, the wiring harness assembly 1 and the manufacturing method of the wiring harness assembly 1 can, for example, lay the wire harness 30 by inserting the wire harness 30 into the laying space portion 12 from the outside of the rigid member 10A through the slit 20. As a result, the wiring harness assembly 1 and the manufacturing method of the wiring harness assembly 1 can improve the laying property of the wire harness WH.

[0084] In addition, in the wiring harness assembly 1 according to the present embodiment, the rigid member 10A is constituted by a body member 10 that forms the skeleton of the vehicle 100. According to this structure, the wiring harness assembly 1 can, for example, lay the wire harness 30 by inserting the wire harness 30 into the laying space portion 12 through the slit 20 for a body member 10 (a sill that forms the lower side member 3) of the vehicle 100 in a state where both ends in the axial direction X of the laying space portion 12 are closed.

[0085] In addition, in the wiring harness assembly 1 according to the present embodiment, the slit 20 has a narrow-width portion 21 formed to be narrower than the outer diameter d of the wire harness 30. According to this structure, the wiring harness assembly 1 can, for example, make the opening width d1 of the slit 20 relatively small through the narrow-width portion 21, and further can suppress the wire harness 30 from coming out of the laying space portion 12 through the slit 20, or can suppress foreign matters and the like from entering the laying space portion 12.

[0086] In addition, in the wiring harness assembly 1 according to the present embodiment, the opening width d1 of the narrow-width portion 21 is formed to be at least wider than the sum of the outer diameter d3 of one wire W having the largest outer diameter among the plurality of wires W constituting the wire harness 30 and the plate thickness d4 of a pair of side walls 5b of the jig 5 for inserting the wire harness 30 into the laying space portion 12 through the slit 20. According to this structure, the wiring harness assembly 1 can, for example, ensure the insertability of the plurality of wires W with respect to the slit 20, and further deform or displace the wire harness 30 by the jig 5 so that the width is narrower than the opening width d1, thereby enabling the wire harness 30 to be inserted into the laying space portion 12 from the outside.

[0087] In addition, in the wiring harness assembly 1 according to the present embodiment, the slit 20 has a wide-width portion 22 that communicates with the narrow-width portion 21 and is formed to be wider than the outer diameter d of the wire harness 30. According to this structure, the wiring harness assembly 1 can, for example, improve the insertability of the wire harness 30 and the jig 5 with respect to the slit 20 through the wide-width portion 22.

[0088] In addition, in the wiring harness assembly 1 of the present embodiment, the slit 20 is provided in the upper wall 11a (first wall portion) of the outer wall 11 facing the interior space of the vehicle 100. According to this structure, the wiring harness assembly 1 can, for example, install the wire harness 30 from the interior space side with respect to the slit 20, and thus can improve the workability of the installation operation of the wiring harness WH.

[0089] In addition, in the wiring harness assembly 1 of the present embodiment, the wire harness 30 includes: a pair of bundling posture maintaining portions 31 located at both end portions 30a in the axial direction X and bundled in a manner to maintain the bundling posture; and a bundling posture variable portion 32 located between the pair of bundling posture maintaining portions 31 in the axial direction X and allowing the bundling posture to be variable. According to this structure, the wiring harness assembly 1 can, for example, bundle a plurality of wires W constituting the wire harness 30 into a bundle by the pair of bundling posture maintaining portions 31, and on this basis, allow deformation, displacement, etc. of the wire harness 30 through the bundling posture variable portion 32, and thus can improve the workability of the installation operation of the wiring harness WH.

[0090] In addition, in the wiring harness assembly 1 of the present embodiment, the bundling posture variable portion 32 is disposed in the layout space portion 12 of the rigid member 10A, and the pair of bundling posture maintaining portions 31 are led out to the outside of the rigid member 10A via the slit 20. According to this structure, the wiring harness assembly 1 can, for example, protect at least a part of the wiring harness WH by the bundling posture variable portion 32 disposed in the layout space portion 12, and can improve the workability of the disassembly operation of the wiring harness WH by the pair of bundling posture maintaining portions 31 led out to the outside of the rigid member 10A via the slit 20.

[0091] [Modification Example]

[0092] Figure 16 is a perspective view of the wiring harness WH of the wiring harness assembly 1 according to the modification example, Figure 17 is a cross-sectional view of the bundling posture variable portion 32 of the wiring harness WH according to the modification example. Figure 16 、 Figure 17 The shown wiring harness assembly 1 has the same structure as the wiring harness assembly 1 of the above-described embodiment. Therefore, the wiring harness assembly 1 can obtain the same functions and effects as those of the above-described embodiment based on the same structure.

[0093] However, in this modification example, as Figure 16 、 Figure 17As shown, the second bundling member 50A is different from the above-described embodiment in that it is composed of a stretchable bundling band or the like. Specifically, in this modification, the second bundling member 50A bundles a plurality of electric wires W more loosely than the first bundling member 40, and is provided at the central portion 30b in the axial direction X of the wire harness 30. The second bundling member 50A bundles the plurality of electric wires W in such a manner that the bundling posture of the wire harness 30, in other words, the cross-sectional shape (refer to Figure 17 ) intersecting the axial direction X of the wire harness 30 is variable.

[0094] The second bundling member 50A has, for example, an inner diameter equivalent to the outer diameter d of the wire harness 30 (refer to Figure 2 ), and is configured to allow deformation of the wire harness 30 along the radial direction. That is, the second bundling member 50A is wound around the plurality of electric wires W in a state where the wire harness 30 can elastically deform. Further, in Figure 17 , the cross-sectional shape at the time of insertion (elastic deformation) of the bundling posture variable portion 32 bundled by the second bundling member 50A with respect to the slit 20 is shown.

[0095] As described above, in the wire harness assembly 1 of this modification, the second bundling member 50A has an inner diameter equal to the outer diameter d of the wire harness 30, and is configured to allow deformation of the wire harness 30 along the radial direction. According to this structure, the wire harness assembly 1 can, for example, allow deformation, displacement, etc. of the wire harness 30 through the second bundling member 50A, and further improve the workability of the installation work of the wire harness WH.

[0096] It should be noted that, in the above-described embodiment and modification, the case where the rigid member 10A is constituted by the body member 10 forming the skeleton of the vehicle 100 is exemplified, but it is not limited to this example. For example, it may also be constituted by a metal exterior member that restricts the wiring path of the wire harness 30. Further, in the above-described embodiment and modification, the case where the slit 20 is provided in the upper wall 11a of the body member 10 (rigid member 10A) is exemplified, but it is not limited to this example. For example, it may also be provided in the side wall 11c on the vehicle interior space side among the pair of side walls 11c and 11d. In this case, the side wall 11c is an example of the first wall portion.

[0097] Further, in the above-described embodiment and the above modification, the case where the slit 20 extends in the axial direction X with respect to the outer wall 11 of the body member 10 (rigid member 10A) is exemplified, but it is not limited to this example. For example, the slit 20 may be configured to include a first portion extending in the axial direction X and a second portion communicating with the first portion and extending in the width direction Y. In this case, for example, the second portion is provided over the upper wall 11a of the outer wall 11 and the side wall 11c on the vehicle interior space side, so that the bundling posture maintaining portion 31 of the wire harness 30 can be led out from the side wall 11c.

[0098] The above has exemplified the embodiments and modification examples of the present invention. However, the above embodiments and modification examples are just examples and are not intended to limit the scope of the invention. The above embodiments and modification examples can be implemented in various other ways, and various omissions, substitutions, combinations, and changes can be made without departing from the gist of the invention. In addition, various specifications (structures, shapes, etc.) such as structures, shapes, etc. (structure, type, direction, form, size, length, width, thickness, height, quantity, arrangement, position, material, etc.) can be appropriately changed and implemented.
