In addition, the present invention is not limited to the following implementation manners and modified examples. Further, among the components in the following implementation manners and modified examples, there are components that can be easily replaced by those skilled in the art, or components that are substantially the same.
[0044] In addition, the same components are included in the implementation manners and modified examples disclosed below. Therefore, hereinafter, these same components are denoted by common reference numerals, and repeated descriptions are omitted. Further, in this specification, ordinal numbers are only used to distinguish elements, components, parts, positions, directions, etc., and do not represent order or priority.
[0045] [Implementation manners]
[0046] Figure 1 It is a perspective view of the vehicle 100 to which the wire harness WH according to the implementation manner is applied, Figure 2 It is a cross-sectional view of the wire harness assembly 1 including the wire harness WH. Figure 1 , Figure 2The wire harness assembly 1 of the present embodiment shown is applicable to vehicles 100 such as automobiles, connects between various devices mounted on the vehicle 100, and is used for power supply and signal communication. The wire harness assembly 1 of the present embodiment includes, for example: a wire harness WH; a mounting member 10A having a predetermined rigidity and provided with a wiring space portion 12 for laying the wire harness WH therein; and a slit 20 provided on the outer wall 11 of the mounting member 10A and capable of inserting the wire harness WH from the outside into the wiring space portion 12. 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 be configured to further include connectors, bellows, grommets, fixing members, etc.
[0047] Here, in the present embodiment, the mounting member 10A is constituted by a body member 10 that forms the skeleton of the vehicle 100. The body member 10 is, for example, a tubular sill that forms a 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 wiring space portion 12 are closed. Moreover, in the present embodiment, the wire harness WH is inserted through the slit 20 and laid in the wiring space portion 12 that is the internal space portion of the main body member 10. Thus, for example, compared with the case where the wire harness WH is laid 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 covered by the fender 4.
[0048] 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 body member 10 (mounting member 10A), etc., and is along the vehicle front-rear direction. The width direction Y typically corresponds to the width direction (left-right direction) of the body member 10 (mounting 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 body member 10 (mounting member 10A), etc., and is along the vehicle up-down direction. 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 the convenience of explanation, the illustration of the plurality of wires W constituting the wire bundle 30 is simplified.
[0049] Figure 3 is a perspective view of the body member 10 of the wire harness assembly 1, Figure 4It is a top view near the wide-width portion 22 of the slit 20 of the wire harness assembly 1. As Figure 3 , Figure 4 shown, the body part 10 is made of, for example, an extruded material of a metal material, and has an outer wall 11 with a rectangular tubular cross-sectional shape intersecting the axial direction X. The outer wall 11 is a structure for partitioning the above-mentioned wiring space portion 12 which is the internal space portion of the body part 10. The wiring 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.
[0050] Both the upper wall 11a and the lower wall 11b extend along a direction orthogonal to the height direction Z, and are provided at intervals in the height direction Z and parallel to each other. The upper wall 11a constitutes the upper end portion of the body part 10, and the lower wall 11b constitutes the lower end portion of the body part 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.
[0051] Both the pair of side walls 11c, 11d extend along a direction orthogonal to the width direction Y, and are provided at intervals in the width direction Y and parallel to each other. The side wall 11c is provided 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 body part 10. The side wall 11d is provided 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 body part 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, etc. The pair of side walls 11c, 11d are formed in a flat plate shape extending horizontally along the axial direction X.
[0052] Here, in the present embodiment, a slit 20 extending along the axial direction X is provided in, for example, the upper wall 11a which is one of the upper wall 11a, the lower wall 11b, and the pair of side walls 11c, 11d constituting the outer wall 11. The upper wall 11a is a partition wall separating the wiring space portion 12 of the body part 10 from the interior space. The wiring space portion 12 is the internal space portion of the body part 10, and the interior space is the external space portion of the body part 10. The slit 20 is a through hole penetrating the upper wall 11a along the height direction Z, and connects the wiring space portion 12 of the body part 10 with the interior space. Thus, the wire harness 30 of the wire harness WH can be inserted into the wiring space portion 12 from the interior space side via the slit 20. In the present embodiment, the upper wall 11a is an example of the first wall portion.
[0053] 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 a width formed to be smaller than the outer diameter d of the wire harness 30 (refer to Figure 2)The narrow opening width d1, 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 across 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.
[0054] 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 combined thickness d4 of the pair of side walls 5b of the jig 5 for inserting the wire harness 30 into the wiring 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-width 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 given in which the plurality of wires W are respectively 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 an outer diameter different from that of the other wires W.
[0055] In addition, in the present embodiment, an example is given in which the slit 20 is configured to include the narrow-width portion 21 and the wide-width portion 22, but it is not limited to this example. For example, the slit 20 may be composed of only the narrow-width portion 21 without the wide-width portion 22. In addition, in the present embodiment, an example is given in which the slit 20 is provided across 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 also 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. Furthermore, in the present embodiment, an example is given in which the vehicle body member 10 has a rectangular tubular cross-sectional shape and the wiring space portion 12 is configured as a closed internal space portion, but it is not limited to this example. For example, the vehicle body member 10 may also be formed to have a substantially U-shaped cross-sectional shape, the wiring space portion 12 is not closed, and in this case, the wiring space portion 12 may also be closed by another member different from the vehicle body member 10.
[0056] Figure 5 is a perspective view of the wire harness WH, Figure 6 is a cross-sectional view of the bundling posture maintaining portion 31 of the wire harness WH, Figure 7It 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 coating covering the core wire. The electric wire W is formed to extend linearly along the axial direction X respectively, and extends with substantially the same diameter in the axial direction X (extension direction). In addition, the cross-sectional shape of the core wire of the electric wire W (the cross-sectional shape intersecting the axial direction X) is formed to be substantially circular, and the cross-sectional shape of the insulating coating is formed to be substantially annular, and the overall cross-sectional shape is formed to be substantially circular.
[0057] 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 of the wire bundle 30 in the axial direction X, 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 provided at the pair of bundling posture maintaining portions 31 respectively. 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, maintaining the cross-sectional shape of the cross-section of the wire bundle 30 intersecting the axial direction X (refer to Figure 6 ).
[0058] 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, for example. That is, the first bundling member 40 is wound around a plurality of electric wires W such that the inner portion and the outer overlapping portion are at the same position in the axial direction X in the overlapping portion. A plurality of electric 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 surrounding a plurality of electric wires W at the same position in the axial direction X of the wire bundle 30 is exemplified, but it is not limited to this example. For example, it can also be formed by helically winding around a plurality of electric wires W at different positions in the axial direction X of the wire bundle 30.
[0059] 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 a plurality of wires W in a looser manner 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 a plurality of 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 7 ) of the wire harness 30 intersecting the axial direction X can be changed.
[0060] 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 wire harness 30 to shift along the radial direction. That is, the second bundling member 50 is wound around a 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 circumferential winding around a plurality of wires W at the same position in the axial direction X of the wire harness 30, or can be formed by helical winding around a 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 interval between the second bundling member 50 and the above-mentioned pair of first bundling members 40 of the wire harness 30.
[0061] In addition, in the present embodiment, a case where the bundling posture variable part 32 bundles a plurality of wires W by 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 and a 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.
[0062] 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 wiring space part 12 of the main 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.
[0063] A pair of side walls 5b are parts 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 arranged parallel to each other with a gap 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.
[0064] 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 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 bottom wall 5a gradually approaches the other end portion 5h in the height direction Z of 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.
[0065] 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 parts that project from the other end portion 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 wiring space portion 12 side of the upper wall 11a at the peripheral portion of the slit 20. The pair of flange walls 5c extend parallel to 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.
[0066] 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 across 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 in the axial direction X 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 jig 5 is inserted into the slit 20.
[0067] 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 across 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) a 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.
[0068] Next, an example of a 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.
[0069] 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. In addition, 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 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.
[0070] 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 (mounting part 10A). In this case, the jig 5 is inserted into, for example, 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 in 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-width part 22 by this first cutting part 5f.
[0071] 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 wiring 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 in 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 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 wiring space part 12.
[0072] 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-width part 21 of the slit 20, for example. 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 wiring 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 such first step S1 to fourth step S4, the wire harness 30 of the wire harness WH can be assembled to the wiring 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 being used in the orientation along the vertical direction (height direction Z) as shown in Figure 9 , Figure 12 etc., and for example, it can also be used in an orientation lying horizontally in the horizontal direction (width direction Y or axial direction X).
[0073] As described above, in the wire harness WH of the present embodiment, the wire bundle 30 is configured to include: 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 capable of varying the bundling posture. According to this structure, the wire harness WH can, for example, bundle a plurality of wires W constituting the wire bundle 30 into a single bundle by using the pair of bundling posture maintaining portions 31, and allow deformation, displacement, etc. of the wire bundle 30 through the bundling posture variable portion 32. As a result, the wire harness WH can improve the workability of the installation work.
[0074] In addition, the wire harness WH of the present embodiment includes: a first bundling member 40 respectively provided at the pair of bundling posture maintaining portions 31 and bundling a plurality of wires W; and a second bundling member 50 provided at the bundling posture variable portion 32 and bundling the plurality of wires W in a manner looser than the first bundling member 40. According to this structure, the wire harness WH can, for example, more easily form a pair of bundling posture maintaining portions 31 and a bundling posture variable portion 32 in the wire bundle 30 by the first bundling member 40 and the second bundling member 50.
[0075] In addition, in the wire harness WH of the present embodiment, the second bundling member 50 has an inner diameter larger than the outer diameter d of the wire bundle 30 and is configured to allow the wire bundle 30 to be displaced along the radial direction. According to this structure, the wire harness WH can, for example, allow displacement, deformation, etc. of the wire bundle 30 through the second bundling member 50, and further improve the workability of the installation work of the wire harness WH.
[0076] [Modification Example]
[0077] Figure 16 is a perspective view of the wire harness WH according to the modification example, Figure 17 is a cross-sectional view of the bundling posture variable portion 32 of the wire harness WH according to the modification example. Figure 16 , Figure 17 The wire harness WH shown has the same structure as the wire harness WH of the above-described embodiment. Therefore, the wire harness WH can obtain the same functions and effects as those of the above-described embodiment based on this same structure.
[0078] 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 formed of a stretchable bundling band or the like. Specifically, in this modified 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, that is, the cross-sectional shape (refer to Figure 17 ) intersecting the axial direction X of the wire harness 30 is variable.
[0079] 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 the wire harness 30 to deform along the radial direction. 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. Further, in Figure 17 , the cross-sectional shape of the variable bundling posture portion 32 after being bundled by the second bundling member 50A with respect to when inserted into the slit 20 (during elastic deformation) is shown.
[0080] As described above, in the wire harness WH of this modified 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 the wire harness 30 to deform along the radial direction. According to this structure, the wire harness WH 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.
[0081] It should be noted that, in the above-described embodiment and modified example, an example where the mounting member 10A is constituted by the body member 10 forming the skeleton of the vehicle 100 is shown, 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 modified example, an example where the slit 20 is provided in the upper wall 11a of the body member 10 (mounting member 10A) is shown, 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.
[0082] Further, in the above-described embodiment and the above-described modified example, an example where the slit 20 extends in the axial direction X with respect to the outer wall 11 of the body member 10 is shown, but it is not limited to this example. For example, the slit 20 may also 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 across 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.
