[0051] [Embodiment]

[0052] Figure 1 is a perspective view of a vehicle 100 to which the body structure 2 according to the application embodiment is applied, Figure 2 is a cross-sectional view of a wire harness assembly 1 including the body structure 2. As Figure 1 , Figure 2As shown, the vehicle body structure 2 of the present embodiment includes, for example: a vehicle body member 10 that forms the skeleton of the vehicle 100 and has a laying space portion 12 for laying a wiring harness WH provided therein; and a slit 20 that is provided on the outer wall 11 of the vehicle body member 10 and through which the wiring harness WH can be inserted from the outside into the laying space portion 12. The wiring harness assembly 1 including the vehicle body structure 2 of the present embodiment can be applied to vehicles 100 such as automobiles, and connects between various devices mounted on the vehicle 100 and is used for power supply and signal communication. In the wiring harness assembly 1, in addition to the vehicle body member 10 and the slit 20, for example, a wiring harness WH is also provided. The wiring harness WH is configured to include a wire bundle 30 (refer to Figure 5 ). In addition, the wiring harness assembly 1 may also be configured to further include connectors, bellows, wire guards, fixing members, etc.

[0053] Here, in the present embodiment, the vehicle body member 10 is, for example, a tubular sill that forms the 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 embodiment, the wiring harness WH is inserted through the slit 20 and laid in the laying space portion 12 that is the internal space portion of the vehicle body member 10. Thereby, for example, compared with the case where the wiring harness WH is laid between the vehicle 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 board and alight more smoothly. The slit 20 is provided on the vehicle 100 in a state of being covered by the fender 4.

[0054] 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 wiring harness WH, the length direction of the vehicle body member 10 (rigid member 10A), etc., and is along the vehicle longitudinal direction. The width direction Y typically corresponds to the width direction (left-right direction) of the vehicle body member 10 (rigid member 10A), etc., and is along the vehicle width direction. The height direction Z typically corresponds to the height direction (up-down direction) of the vehicle body member 10 (rigid member 10A), etc., and is along the vehicle up-down direction. In addition, unless otherwise specified, each direction used in the following description is described in the state where the wiring harness assembly 1 is assembled to the vehicle 100. In addition, in Figure 2 and Figure 8 etc., for the sake of convenience, the illustration of the multiple wires W that constitute the wire bundle 30 is simplified.

[0055] Figure 3 is a perspective view of the vehicle body member 10 of the vehicle body structure 2,Figure 4 is a top view near the wide portion 22 of the slit 20 of the vehicle body structure 2. As Figure 3 , Figure 4 shown, the vehicle body member 10 is constituted by, for example, an extruded material of a metal material, and has a cylindrical outer wall 11 having a rectangular cross-sectional shape intersecting the axial direction X. The outer wall 11 is a structure for partitioning the above-described layout space portion 12 that is the internal space portion of the vehicle body member 10. The layout space portion 12 is a space portion through which the wire harness 30 of the wire harness WH is inserted and laid out. 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.

[0056] Both the upper wall 11a and the lower wall 11b extend in a direction orthogonal to the height direction Z, and are provided 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 member 10, and the lower wall 11b constitutes the lower end portion of the vehicle body member 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 extending horizontally along the axial direction X.

[0057] Both the pair of side walls 11c, 11d extend in a direction orthogonal to the width direction Y, and are provided parallel to each other with a space therebetween in the width direction Y. The side wall 11c extends 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 member 10. The side wall 11d extends 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 member 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, 11d are formed in a flat plate shape extending horizontally along the axial direction X.

[0058] Here, in the present embodiment, among the upper wall 11a, the lower wall 11b, and the pair of side walls 11c, 11d constituting 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 member 10 from the interior space of the vehicle. The layout space portion 12 is the internal space portion of the vehicle body member 10, and the interior space of the vehicle is the external space portion of the vehicle body member 10. The slit 20 is a through hole that penetrates the upper wall 11a along the height direction Z, and connects the layout space portion 12 of the vehicle body member 10 and 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.

[0059] In addition, the slit 20 is configured to include, for example, a narrow portion 21 and a wide portion 22. The narrow portion 21 is formed to have a width ratio to the outer diameter d of the wire harness 30 (refer toFigure 2 ) The narrow opening width d1, and the wide portion 22 has an opening width d2 formed wider than the outer diameter d of the wire harness 30. The opening width d1 is the opening width of the narrow portion 21 along the width direction Y, and the opening width d2 is the opening width of the wide portion 22 along the width direction Y. In the present embodiment, the narrow 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 portion 22 is partially provided on the other end portion side of the narrow portion 21 in the axial direction X and communicates with the narrow portion 21. The wide portion 22 functions as an entrance opening when inserting a jig 5 (refer to Figures 8 - 10 ) into the slit 20, for example.

[0060] Further, in the present embodiment, the opening width d1 of the narrow 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 combined width of 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 (refer to Figure 9 ). Specifically, in the present embodiment, the plurality of wires W are configured to have equal outer diameters with each other, and the opening width d1 of the narrow portion 21 is set to the combined width of the outer diameters d3 of about 2 or 3 wires of the plurality of wires W. In addition, in the present embodiment, an example is shown in which the plurality of wires W are configured to have equal outer diameters with each other, but it is not limited to this example. For example, at least one of the plurality of wires W may be configured to have a different outer diameter from the other wires W.

[0061] Further, in the present embodiment, an example is shown 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 constituted only by the narrow portion 21. In addition, in the present embodiment, an example is shown in which the slit 20 is provided between one end portion and the other end portion of the upper wall 11a in the axial direction X, but it is not limited to this example. For example, it may be partially provided at an intermediate position between one end portion and the other end portion of the upper wall 11a in the axial direction X. Further, in the present embodiment, an example is shown in which the vehicle 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 vehicle 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 vehicle body member 10.

[0062] Figure 5 is a perspective view of a wire harness WH applicable to the vehicle body structure 2, Figure 6 is a cross-sectional view of a bundling posture maintaining portion 31 of the wire harness WH,Figure 7 It is a cross-sectional view of the portion 32 where the bundling posture of the wire harness WH can be changed. 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 covering that covers the core wire. The electric wire W is formed to linearly extend along the axial direction X respectively, and extends with substantially the same diameter with respect to 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 intersecting the axial direction X) is formed in a substantially circular shape, and the cross-sectional shape of the insulating covering is formed in a substantially annular shape, and the overall cross-sectional shape is formed in a substantially circular shape.

[0063] In addition, the wire bundle 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 bundle 30, and are portions bundled in a manner of maintaining the bundling posture. In the present embodiment, first bundling members 40 for bundling a plurality of electric wires W are respectively provided at the pair of bundling posture maintaining portions 31. The pair of first bundling members 40 can be, for example, bundling members such as bundling tapes, or tape members such as tapes, or other members. The first bundling member 40 bundles a plurality of electric wires W in a manner of maintaining the bundling posture of the wire bundle 30, in other words, the cross-sectional shape intersecting the axial direction X of the wire bundle 30 (refer to Figure 6 ).

[0064] The first bundling member 40 surrounds a plurality of electric wires W at the same position in the axial direction X of the wire bundle 30. That is, in the overlapping portions of the first bundling member 40, the inner portion and the outer overlapping portion are at the same position in the axial direction X, and the first bundling member 40 is wound around a plurality of electric wires W. A plurality of electric wires W are exposed in the interval between one and the other of the pair of first bundling members 40 of the wire bundle 30. It should be noted that in the present embodiment, an example is shown in which the first bundling member 40 is formed by surrounding winding around the periphery of a plurality of electric wires W at the same position in the axial direction X of the wire bundle 30, but it is not limited to this example. For example, it can also be formed by spiral winding around the periphery of a plurality of electric wires W at different positions in the axial direction X of the wire bundle 30.

[0065] The bundling posture variable part 32 is a part in the wire harness 30 that is located between a pair of bundling posture maintaining parts 31 in the axial direction X and can change the bundling posture. In the present embodiment, a second bundling member 50 that bundles multiple wires W more loosely than the first bundling member 40 is provided at the bundling posture variable part 32. The second bundling member 50 is provided, for example, at the central part 30b of the wire harness 30 in the axial direction X. The second bundling member 50 can be, for example, a bundling member such as a bundling band, a tape member such as a tape, or other members. The second bundling member 50 bundles the multiple wires W in such a way that the bundling posture of the wire harness 30, in other words, the cross-sectional shape (refer to Figure 7 ) intersecting the axial direction X of the wire harness 30, can be changed.

[0066] The second bundling member 50 has, for example, an inner diameter larger than the outer diameter d of the wire harness 30 (refer to Figure 2 ) and is configured to allow the radial displacement of the wire harness 30. That is, the second bundling member 50 is wound around the multiple wires W in such a way that the multiple wires W can move relative to each other and disperse. The second bundling member 50 can be formed, for example, by circumferentially winding around the multiple wires W at the same position in the axial direction X of the wire harness 30, or by helically winding around the multiple wires W at different positions in the axial direction X of the wire harness 30. Multiple wires W are exposed in the section of the wire harness 30 between the second bundling member 50 and the above-mentioned pair of first bundling members 40.

[0067] In addition, in the present embodiment, the case where the bundling posture variable part 32 bundles the multiple wires W through the second bundling member 50 is exemplified, but it is not limited to this example. For example, the second bundling member 50 may not be provided so as not to bundle the multiple wires W. That is, the bundling posture variable part 32 also includes a form in which there is no bundling member such as the second bundling member 50 itself. 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.

[0068] 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 part 12 of the vehicle body part 10 through the slit 20. The jig 5 is formed, for example, by a flexible flexure member 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 part 5f, and a second cutting part 5e.

[0069] A pair of side walls 5b are parts of the fixture 5 that hold the wire harness 30 from both sides in the width direction Y. The pair of side walls 5b both extend along a direction orthogonal to the width direction Y, and are arranged in parallel with a space therebetween in the width direction Y. One of the pair of side walls 5b constitutes the right end portion of the fixture 5, and the other of the pair of side walls 5b constitutes the left end portion of the fixture 5. The pair of side walls 5b are formed in a flat plate shape that extends horizontally along the axial direction X.

[0070] The bottom wall 5a is a part that extends in an arc shape along the outer peripheral surface of the wire harness 30 and connects the one end portions 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 fixture 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 into 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.

[0071] A pair of flange walls 5c are provided at the other end portions 5h in the height direction Z of the pair of side walls 5b, and are parts that project from the other end portions 5h along the width direction Y toward the separated side. 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.

[0072] 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 part that extends along the height direction Z over the bottom wall 5a and the other end portions 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 that faces 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 part that suppresses snagging when the fixture 5 is inserted into the slit 20.

[0073] 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 part that extends along the height direction Z over the bottom wall 5a and the pair of side walls 5b when viewed from the width direction Y (refer to Figure 10) is a portion that extends along the inclined direction between the height direction Z and the axial direction X over the bottom wall 5a and one end portion 5j of the pair of side walls 5b. The second cutting portion 5e is provided at the end portion 5j side in the axial direction X at the corner portion 5n where the bottom wall 5a intersects the pair of side walls 5b. The second cutting portion 5e has a flat end face facing the side in the axial direction X and the 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 snagging when the jig 5 is inserted into the slit 20.

[0074] Next, an example of the manufacturing method of the wire harness assembly 1 having the above structure will be described. Figure 11 is a flowchart of the manufacturing method of the wire harness assembly 1, Figure 12 is a perspective view of the wire harness assembly 1 and is a view showing the first step S1, Figure 13 is a perspective view of the wire harness assembly 1 and is a view showing the second step S2, Figure 14 is a perspective view of the wire harness assembly 1 and is a view showing the third step S3, Figure 15 is a perspective view of the wire harness assembly 1 and is a view showing the fourth step S4.

[0075] First, in the process of the first step S1, as Figure 11 , Figure 12 shown, the wire bundle 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 bundle 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 bundle 30 (axial direction X). In this case, the jig 5 is inclined so that one end portion 5j in the axial direction X approaches the slit 20 located on the other side in the height direction Z than the other end portion 5k.

[0076] 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, for example, into the wide-width part 22 of the slit 20 and is inserted obliquely with respect to the wide-width 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 one end part 5j in the axial direction X of the jig 5 is prevented from hooking on the edge part of the wide-width part 22 by this second cutting part 5e. Then, the jig 5 inserted obliquely with respect to the wide-width part 22 is pressed into the side in the axial direction X so that the pair of flange walls 5c of the jig 5 is 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-width part 22 by this first cutting part 5f.

[0077] Next, in the process of the third step S3, as Figure 11 , Figure 14 shown, by sliding the jig 5 along the narrow-width part 21 of the slit 20, the wire harness 30 is deformed or displaced so that the width is 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 is 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 side, and as the jig 5 slides and moves toward the 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.

[0078] Then, in the process of the fourth step S4, as Figure 11 , Figure 15 shown, the jig 5 is detached from the slit 20. In this case, the jig 5 is pulled out obliquely with respect to the narrow-width 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 like this, the wire harness 30 of the wire harness WH can be assembled to the laying space part 12 of the vehicle body part 10, and the wire harness assembly 1 can be manufactured. In addition, the jig 5 is not limited to Figure 9 , Figure 12 the use in the orientation along the vertical direction (height direction Z) as shown, etc., and for example, it can also be used in an orientation laid down in the horizontal direction (width direction Y or axial direction X).

[0079] As described above, in the vehicle body structure 2 of the present embodiment, a slit 20 is provided in the outer wall 11 of the vehicle body member 10. The slit 20 extends along the axial direction X, and the wire harness 30 can be inserted from the outside into the laying space portion 12. According to this structure, the vehicle body structure 2 can, for example, insert the wire harness 30 from the outside of the vehicle body member 10 into the laying space portion 12 through the slit 20 for laying. As a result, the vehicle body structure 2 can improve the laying property of the wire harness WH.

[0080] In addition, in the vehicle body structure 2 of 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 vehicle body structure 2 can, for example, make the opening width d1 of the slit 20 smaller through the narrow-width portion 21, and further can suppress the wire harness 30 from coming out of the laying space portion 12 via the slit 20, or can suppress foreign matters and the like from entering the laying space portion 12.

[0081] In addition, in the vehicle body structure 2 of 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 vehicle body structure 2 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 through the jig 5 so that the width is narrower than the opening width d1, thereby enabling the wire harness 30 to be inserted from the outside into the laying space portion 12.

[0082] In addition, in the vehicle body structure 2 of 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 wire 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.

[0083] In addition, in the vehicle body structure 2 of the present embodiment, the vehicle body member 10 is a sill that constitutes the side beam 3 of the vehicle 100. According to this structure, the vehicle body structure 2 can, for example, insert the wire harness 30 into the laying space portion 12 through the slit 20 for laying with respect to the vehicle body member 10 (the sill that constitutes the side beam 3) in a state where both ends in the axial direction X of the laying space portion 12 are closed in the vehicle 100.

[0084] In addition, in the vehicle body structure 2 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 vehicle body structure 2 can, for example, mount the wire harness 30 on the slit 20 from the interior space side of the vehicle, and further can improve the workability of the installation work of the wire harness WH.

[0085] [Modification Example]

[0086] Figure 16 is a perspective view of the wire harness WH of the wire harness assembly 1 related to the modification example, Figure 17 is a cross-sectional view of the variable bundling portion 32 of the wire harness WH related to the modification example. Figure 16 , Figure 17 The wire harness assembly 1 shown has the same structure as the wire harness assembly 1 of the above-described embodiment. Therefore, the wire harness assembly 1 can obtain the same functions and effects as the above-described embodiment based on the same structure.

[0087] However, in this modification example, as shown in Figure 16 , Figure 17 , the second bundling member 50A is composed of a stretchable bundling tape or the like, which is different from the above-described embodiment in this regard. Specifically, in this modification example, the second bundling member 50A bundles a plurality of electric wires W in a looser manner 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 a 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.

[0088] 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 in the radial direction of the wire harness 30. That is, the second bundling member 50A is wound around a plurality of electric wires W in a state where the wire harness 30 can elastically deform. In addition, Figure 17 shows the cross-sectional shape of the variable bundling portion 32 after being bundled by the second bundling member 50A when inserted (elastically deformed) with respect to the slit 20.

[0089] As described above, in the wire harness assembly 1 of this modification example, 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 in the radial direction of the wire harness 30. 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 operation of the wire harness WH.

[0090] In addition, in the above-described embodiment and the modification example, the case where the slit 20 is provided on the upper wall 11a of the vehicle body member 10 is illustrated, but it is not limited to this example. For example, it may be provided on 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.

[0091] In addition, in the above-described embodiments and the above-described modification examples, the case where the slit 20 extends along the axial direction X with respect to the outer wall 11 of the vehicle body member 10 is illustrated, but it is not limited to this example. For example, the slit 20 may be configured to include a first portion extending along the axial direction X and a second portion communicating with the first portion and extending along 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.

[0092] As described above, the embodiments and modification examples of the present invention have been illustrated, but the above-described embodiments and modification examples are merely examples and are not intended to limit the scope of the invention. The above-described 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 such as each structure, shape, etc. (structure, type, direction, form, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be appropriately changed and implemented.
