In this case, there is room for further improvement in terms of improving the workability of the attachment work.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a jig capable of improving the workability of attachment work.

Means for Solving the Problems

[0006] To achieve the above object, the jig according to the present invention includes a pair of side walls that hold a wire bundle in which a plurality of wires extending along the axial direction are bundled from both sides in the width direction intersecting the axial direction, and an outer peripheral surface of the wire bundle. A bottom wall that extends in an arc shape along the wall and connects one end portion in the height direction intersecting the axial direction and the width direction of the pair of side walls, and the pair of side walls are provided on the outer wall of the mounting member at the other end portion in the height direction. It is configured to be insertable into the wire routing space portion of the mounting member through a slit, and the bottom wall and the pair of side walls are arranged from one end side in the axial direction toward the other end side, and the bottom wall is the pair of side walls. It is formed in a tapered shape that gradually approaches the other end portion in the height direction, and on the other end side in the axial direction, a first cut portion extending along the height direction is provided across the bottom wall and the other end portion in the height direction of the pair of side walls when viewed from the width direction.

Effect of the Invention

[0007] In the jig according to the present invention, the bottom wall and the pair of side walls are formed in a tapered shape in which the bottom wall gradually approaches the other end portion in the height direction of the pair of side walls as it goes from one end side in the axial direction to the other end side, and on the other end side in the axial direction, a width is provided. A first cut portion extending along the height direction is provided across the bottom wall and the other end portion in the height direction of the pair of side walls when viewed from the direction. With this configuration, the jig can, for example, prevent the other end portions in the axial direction of the bottom wall and the pair of side walls from being caught by the slit of the mounting member due to the first cut portion. As a result, the jig has the effect of improving the workability of the mounting operation.

Best Mode for Carrying Out the Invention

[0009] Hereinafter, embodiments and modifications according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiments and modifications. In addition, the components in the following embodiments and modifications include those that can be replaced by those skilled in the art and are easy to replace, or those that are substantially the same.

[0010] In addition, the embodiments and modifications disclosed below include similar components. Therefore, in the following, the same reference numerals are given to those similar components, and redundant descriptions are omitted. Note that in this specification, ordinal numbers are used only for distinguishing parts, members, parts, positions, directions, etc., and do not indicate order or priority.

[0011] [Embodiment] FIG. 1 is a perspective view of a vehicle 100 to which a wire harness assembly WH according to an embodiment is applied, and FIG. 2 is a cross-sectional view of a wire harness assembly 1 to which a jig 5 according to the embodiment is applied. The wire harness assembly 1 of the present embodiment shown in FIGS. 1 and 2 is applied to a vehicle 100 such as an automobile, and is used to connect between each device mounted on the vehicle 100 and 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 provided with a wiring space portion 12 having a predetermined rigidity and in which the wire harness WH is wired, and a slit 20 provided on the outer wall 11 of the mounting member 10A and allowing the wire harness WH to be inserted into the wiring space portion 12 from the outside. The wire harness WH includes a wire bundle 30 (see FIG. 5) in which a plurality of conductive wires W are bundled. Note that the wire harness assembly 1 may further include a connector, a corrugated tube, a grommet, a fixture, and the like.

[0012] Here, in the present embodiment, the attachment member 10A is constituted by a body member 10 that forms the framework of the vehicle 100. The body member 10 is, for example, a cylindrical rocker that forms the side sill 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. And in the present embodiment, a wire harness WH is inserted and routed through a slit 20 into the wiring space portion 12 as the internal space portion of the body member 10. Thereby, for example, compared with the case where the wire harness WH is routed between the body member 10 and the scuff plate 4, the position of the scuff plate 4 can be set lower, and as a result, the opening area of the entrance / exit of the vehicle 100 can be widened and the passengers can get on and off more smoothly. The slit 20 is installed in the vehicle 100 in a state covered by the scuff plate 4, for example.

[0013] 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 longitudinal direction of the body member 10 (attachment 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 (attachment 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 (attachment member 10A), etc., and is along the vehicle up-down direction. Also, each direction used in the following description will be described as the direction in a state where the wire harness assembly 1 is assembled to the vehicle 100 unless otherwise specified. In FIGS. 2, 8, etc., for the sake of convenience, the illustration of the plurality of electric wires W constituting the wire bundle 30 is simplified.

[0014] FIG. 3 is a perspective view of the body member 10 of the wire harness assembly 1, and FIG. 4 is a plan view of the vicinity of the wide portion 22 of the slit 20 of the wire harness assembly 1. As shown in FIGS. 3 and 4, the body member 10 is formed 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-described wire routing space portion 12 as the internal space portion of the body member 10. The wire routing space portion 12 is a space portion through which the wire bundle 30 of the wire harness WH is inserted and routed. The outer wall 11 includes, for example, an upper wall 11a, a lower wall 11b, and a pair of side walls 11c and 11d.

[0015] Both the upper wall 11a and the lower wall 11b extend along 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 body member 10, and the lower wall 11b constitutes the lower end portion of the 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.

[0016] Both the pair of side walls 11c and 11d extend along 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 spans 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 member 10. The side wall 11d spans 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 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 and 11d are formed in a flat plate shape extending horizontally along the axial direction X.

[0017] Here, in the present embodiment, among the upper wall 11a, the lower wall 11b, and the pair of walls 11c and 11d that constitute the outer wall 11, for example, in the upper wall 11a facing the passenger compartment space, a slit 20 extending along the axial direction X is provided. The upper wall 11a is a partition wall that separates the wiring space portion 12 of the body member 10 from the passenger compartment space. The wiring space portion 12 is an internal space portion of the body member 10, and the passenger compartment space is an external space portion of the body member 10. The slit 20 is a through-hole that penetrates the upper wall 11a along the height direction Z, and communicates the wiring space portion 12 of the body member 10 with the passenger compartment space. Thereby, the wire bundle 30 of the wire harness WH can be inserted into the wiring space portion 12 from the passenger compartment space side through the slit 20. In the present embodiment, the upper wall 11a is an example of the first wall portion.

[0018] Further, 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 narrower than the outer diameter d (see FIG. 2) of the wire bundle 30, and the wide-width portion 22 has an opening width d2 formed wider than the outer diameter d of the wire bundle 30. The opening width d1 is the opening width along the width direction Y of the narrow-width portion 21, and the opening width d2 is the opening width along the width direction Y of the wide-width portion 22. In the present embodiment, the narrow-width portion 21 is provided across 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 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, for example, as an entrance opening when inserting a jig 5 (see FIGS. 8 to 10) described later into the slit 20.

[0019] Further, in the present embodiment, the opening width d1 of the narrow portion 21 is formed wider than the sum of the outer diameter d3 of one of the wires W having the largest outer diameter among the plurality of wires W constituting the wire bundle 30 (see FIG. 6) and the plate thickness d4 of the pair of side walls 5b of the jig 5 for inserting the wire bundle 30 into the wiring space portion 12 via the slit 20 (see FIG. 9). Specifically, in the present embodiment, the plurality of 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 wires W. In the present embodiment, the case where the plurality of wires W are configured to have the same outer diameter as each other is exemplified, but the present invention 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.

[0020] Further, in the present embodiment, the slit 20 is exemplified as being configured to include the narrow portion 21 and the wide portion 22, but the present invention is not limited to this example. For example, the slit 20 may be configured only by the narrow portion 21 without the wide portion 22. Further, in the present embodiment, the slit 20 is exemplified as being provided across one end portion and the other end portion in the axial direction X of the upper wall 11a, but the present invention is not limited to this example. For example, the slit 20 may be partially provided at an intermediate position between one end portion and the other end portion in the axial direction X of the upper wall 11a. Further, in the present embodiment, the body member 10 is exemplified as having a rectangular tubular cross-sectional shape and being configured as a closed internal space portion of the wiring space portion 12, but the present invention 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 wiring space portion 12 may not be closed. Further, in this case, the wiring space portion 12 may be closed by another member different from the body member 10.

[0021] FIG. 5 is a perspective view of the wire harness WH, FIG. 6 is a cross-sectional view of the binding posture maintaining portion 31 of the wire harness WH, and FIG. 7 is a cross-sectional view of the binding posture variable portion 32 of the wire harness WH. As shown in FIGS. 5 to 7, the wire harness WH has, for example, a wire bundle 30 in which a plurality of electric wires W are bundled. The electric wire W is composed of a core wire and an insulating coating covering the core wire. The electric wires W each linearly extend along the axial direction X and are formed to extend with substantially the same diameter with respect to the axial direction X (extending direction). Further, the electric wire W is formed such that, for example, the cross-sectional shape of the core wire (the cross-sectional shape intersecting the axial direction X) is substantially circular, and the cross-sectional shape of the insulating coating is substantially annular, and the overall cross-sectional shape is substantially circular.

[0022] Further, the wire bundle 30 is composed of, for example, a pair of binding posture maintaining portions 31 and a binding posture variable portion 32. The pair of binding 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 so as to maintain the binding posture. In the present embodiment, a first binding member 40 for bundling a plurality of electric wires W is provided in each of the pair of binding posture maintaining portions 31. The pair of first binding members 40 may be, for example, a binding member such as a binding band, a tape member such as an adhesive tape, or other members. The first binding member 40 binds a plurality of electric wires W so as to maintain the binding posture of the wire bundle 30, in other words, the cross-sectional shape (see FIG. 6) intersecting the axial direction X of the wire bundle 30.

[0023] The first bundling member 40 circulates around a plurality of electric wires W at the same position in the axial direction X of the wire bundle 30. That is, the first bundling member 40 is wound around the plurality of electric wires W such that, at the overlapping portions, the inner portion and the outer overlapping portion are at the same position in the axial direction X. The wire bundle 30 has a plurality of electric wires W exposed in the section between one and the other of the pair of first bundling members 40. In the present embodiment, the case where the first bundling member 40 is formed by a circumferential winding that circulates around the plurality of electric wires W at the same position in the axial direction X of the wire bundle 30 is illustrated, but the present invention is not limited to this example. For example, it may be formed by a spiral winding that circulates around the plurality of electric wires W at different positions in the axial direction X of the wire bundle 30.

[0024] The bundling posture variable portion 32 is located between the pair of bundling posture maintaining portions 31 in the axial direction X of the wire bundle 30 and is the portion where the bundling posture is variable. In the present embodiment, the bundling posture variable portion 32 is provided with a second bundling member 50 that bundles the plurality of electric wires W more loosely than the first bundling member 40. The second bundling member 50 is provided, for example, at the central portion 30b in the axial direction X of the wire bundle 30. The second bundling member 50 may be, for example, a bundling member such as a bundling band, a tape member such as an adhesive tape, or other members. The second bundling member 50 bundles the plurality of electric wires W such that the bundling posture of the wire bundle 30, in other words, the cross-sectional shape (see FIG. 7) intersecting the axial direction X of the wire bundle 30, is variable.

[0025] The second bundling member 50 has an inner diameter larger than the outer diameter d (see FIG. 2) of the wire bundle 30, and is configured to allow displacement along the radial direction of the wire bundle 30. That is, the second bundling member 50 is wound around a plurality of wires W so that the plurality of wires W can move relative to each other and become loose. The second bundling member 50 may be formed, for example, by circumferentially winding around the plurality of wires W at the same position in the axial direction X of the wire bundle 30, or may be formed by helically winding around the plurality of wires W at different positions in the axial direction X of the wire bundle 30. A plurality of wires W are exposed in the section of the wire bundle 30 between the second bundling member 50 and the pair of first bundling members 40 described above.

[0026] In addition, in the present embodiment, the bundling posture variable portion 32 is exemplified by the case where the plurality of wires W are bundled by the second bundling member 50, but is not limited to this example. For example, the plurality of wires W may not be bundled without providing the second bundling member 50. That is, the bundling posture variable portion 32 includes a form in which there is no bundling member itself such as the second bundling member 50. The bundling posture variable portion 32 is also referred to as a cross-sectional shape variable portion or the like, and the bundling posture maintaining portion 31 is also referred to as a cross-sectional shape maintaining portion or the like.

[0027] FIG. 8 is an exploded perspective view of the wire harness assembly 1, FIG. 9 is a perspective view of the jig 5, and FIG. 10 is a side view of the jig 5. As shown in FIGS. 8 to 10, the jig 5 is used, for example, when inserting the wire bundle 30 of the wire harness WH into the wiring space portion 12 of the body member 10 through the slit 20. The jig 5 is formed of a flexible member such as synthetic resin, and includes a bottom wall 5a, a pair of side walls 5b, a pair of flange walls 5c, a first cut portion 5f, and a second cut portion 5e.

[0028] The pair of side walls 5b are the portions of the jig 5 that hold the wire bundle 30 from both sides in the width direction Y. Both of the pair of side walls 5b extend along a direction orthogonal to the width direction Y, and are provided in parallel with each other at an interval 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.

[0029] The bottom wall 5a extends in an arc shape along the outer peripheral surface of the wire bundle 30, and is the portion that connects the one end portions 5g in the height direction Z of the pair of side walls 5b. The bottom wall 5a has a substantially U-shaped cross section that is open 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 bundle 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 inclines 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 one end portion 5j side to the other end portion 5k side in the axial direction X. Thereby, the insertability of the wire bundle 30 into the slit 20 is enhanced. That is, the bottom wall 5a functions as a guide when the wire bundle 30 is inserted into the slit 20.

[0030] The 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 the portions that protrude toward the sides that are separated from each other along the width direction Y from the other end portion 5h. The pair of flange walls 5c are slidably locked to the peripheral edge portion of the slit 20 on the inner surface 11a1 (see FIG. 12) of the upper wall 11a on the wiring space portion 12 side. 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.

[0031] The first cut portion 5f is provided on 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 extending along the height direction Z across the bottom wall 5a and the other end portion 5h of the pair of side walls 5b in a line of sight from the width direction Y (see FIG. 10). The first cut portion 5f has a flat end face facing the other side in the axial direction X. The first cut 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 cut portion 5f is perpendicular to the pair of flange walls 5c. The first cut portion 5f functions, for example, as a portion for suppressing snagging during insertion into the slit 20 of the jig 5.

[0032] The second cut portion 5e is provided on 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 extending along the inclination direction between the height direction Z and the axial direction X across the bottom wall 5a and the one end portion 5j of the pair of side walls 5b in a line of sight from the width direction Y (see FIG. 10). The second cut portion 5e is provided at the corner portion 5n where the bottom wall 5a and the pair of side walls 5b intersect on the one end portion 5j side in the axial direction X. The second cut portion 5e has a flat end face facing one side in the axial direction X and one side in the height direction Z. The second cut 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 inclination direction between the height direction Z and the axial direction X. The second cut portion 5e is inclined with respect to the pair of flange walls 5c, the first cut portion 5f, etc. The second cut portion 5e functions, for example, as a portion for suppressing snagging during insertion into the slit 20 of the jig 5.

[0033] Next, an example of a manufacturing method of the wire harness assembly 1 having the above configuration will be described. FIGS. 11 is a flowchart of the manufacturing method of the wire harness assembly 1, FIG. 12 is a perspective view of the wire harness assembly 1 showing the first step S1, FIG. 13 is a perspective view of the wire harness assembly 1 showing the second step S2, FIG. 14 is a perspective view of the wire harness assembly 1 showing the third step S3, and FIG. 15 is a perspective view of the wire harness assembly 1 showing the fourth step S4.

[0034] First, in the process of the first step S1, as shown in FIGS. 11 and 12, a wire bundle 30 in which a plurality of electric wires W are bundled is held by a jig 5. In this case, the pair of side walls 5b of the jig 5 hold the above-described binding posture variable portion 32 of the wire bundle 30 from both sides in the width direction Y, and the binding 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 tilted 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 tilted 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.

[0035] Next, in the process of the second step S2, as shown in FIGS. 11 and 13, the jig 5 is inserted into the slit 20 provided in the outer wall 11 of the body member 10 (mounting member 10A). In this case, the jig 5 is inserted into, for example, the wide portion 22 of the slit 20 and is inserted obliquely with respect to the wide portion 22. At this time, in the present embodiment, since the second cut portion 5e described above is provided at one end portion 5j in the axial direction X of the jig 5, the one end portion 5j in the axial direction X of the jig 5 is prevented from being caught by the edge portion of the wide portion 22 by the second cut portion 5e. Then, the jig 5 inserted obliquely with respect to the wide portion 22 is pushed into one side in the axial direction X, and the posture of the jig 5 is returned so that the pair of flange walls 5c of the jig 5 is parallel to the upper wall 11a. At this time, in the present embodiment, since the first cut portion 5f described above is provided at the other end portion 5k in the axial direction X of the jig 5, the other end portion 5k in the axial direction X of the jig 5 is prevented from being caught by the edge portion of the wide portion 22 by the first cut portion 5f.

[0036] Next, in the process of the third step S3, as shown in FIGS. 11 and 14, by sliding the jig 5 along the narrow portion 21 of the slit 20, the wire harness 30 is deformed or displaced so as to be narrower than the opening width d1 of the slit 20, and the wire harness 30 is inserted into the wiring space portion 12 of the body member 10 from the outside. In this case, the pair of flange walls 5c of the jig 5 is slidably locked to the peripheral edge portion of the slit 20 on the inner surface 11a1 of the upper wall 11a. The bundling posture variable portion 32 of the wire harness 30 is guided to the slit 20 side by the bottom wall 5a of the jig 5, and as the jig 5 slides axially X to one side with respect to the upper wall 11a, the bundling posture variable portion 32 drops from the opening 5d between the pair of side walls 5b through the slit 20 into the wiring space portion 12.

[0037] Then, in the process of the fourth step S4, as shown in FIGS. 11 and 15, the jig 5 is removed from the slit 20. In this case, the jig 5 is pulled out obliquely with respect to the narrow portion 21 of the width of the slit 20, for example. When the wire harness 30 is assembled to the body member 10, the variable bundling posture portion 32 at the central portion 30b in the axial direction X of the wire harness 30 is routed in the wiring space portion 12, and the pair of bundling posture maintaining portions 31 at both ends 30a in the axial direction X are pulled out to the outside of the body member 10 through the slit 20. By the first step S1 to the fourth step S4 as described above, the wire harness 30 of the wire harness WH can be assembled to the wiring space portion 12 of the body member 10, and the wire harness assembly 1 can be manufactured. Note that the jig 5 is not limited to being used in the direction along the vertical direction (height direction Z) as shown in FIGS. 9 and 12, and may be used, for example, in a direction laid horizontally (width direction Y or axial direction X).

[0038] As described above, in the jig 5 of the present embodiment, the bottom wall 5a and the pair of side walls 5b are formed in a tapered shape in which the bottom wall 5a gradually approaches the other end 5h in the height direction Z of the pair of side walls 5b as it goes from one end 5j side to the other end 5k side in the axial direction X, and at the other end 5k side in the axial direction X, a first cut portion 5f extending along the height direction Z is provided across the bottom wall 5a and the other end 5h in the height direction Z of the pair of side walls 5b as viewed from the width direction Y. With this configuration, the jig 5 can suppress, for example, the other end 5k in the axial direction X of the bottom wall 5a and the pair of side walls 5b from being caught by the slit 20 of the body member 10 (attachment member 10A). As a result, the jig 5 can improve the workability of the attachment work.

[0039] In addition, in the jig 5 of the present embodiment, the pair of side walls 5b are provided at the other end portion 5h in the height direction Z, project toward the sides spaced apart from each other along the width direction Y, and have a pair of flange walls 5c that are slidably locked to the inner surface 11a1 on the wiring space portion 12 side of the outer wall 11. With this configuration, the jig 5 can be slid with respect to the inner surface 11a1 of the outer wall 11 by the pair of flange walls 5c, for example, and thus the workability of the attachment work of the wire bundle 30 can be further improved.

[0040] In addition, in the jig 5 of the present embodiment, the bottom wall 5a and the pair of side walls 5b are provided at a corner portion 5n where the bottom wall 5a and the pair of side walls 5b intersect on one end portion 5j side in the axial direction X, and include a second cut portion 5e that extends along the inclination direction between the height direction Z and the axial direction X across the bottom wall 5a and one end portion 5j in the axial direction X of the pair of side walls 5b as viewed from the width direction Y. With this configuration, the jig 5 can suppress, for example, the catching of the one end portion 5j side of the jig 5 in the axial direction X with respect to the slit 20 by the second cut portion 5e, and thus the workability of the attachment work can be further improved.

[0041] [Modification Example] FIG. 16 is a perspective view of a wire harness WH according to a modification example, and FIG. 17 is a cross-sectional view of a binding posture variable portion 32 of the wire harness WH according to the modification example. The wire harness WH shown in FIGS. 16 and 17 has the same configuration as the wire harness WH of the above-described embodiment. Therefore, the wire harness WH can obtain the same operations and effects as those of the above-described embodiment based on the same configuration.

[0042] However, in this modification example, as shown in FIGS. 16 and 17, the second binding member 50A is different from the above-described embodiment in that it is constituted by an elastic binding band or the like. Specifically, in this modification example, the second binding member 50A loosely bundles a plurality of electric wires W more loosely than the first binding member 40, and is provided at the central portion 30b in the axial direction X of the wire bundle 30. The second binding member 50A binds a plurality of electric wires W so that the binding posture of the wire bundle 30, in other words, the cross-sectional shape (see FIG. 17) intersecting the axial direction X of the wire bundle 30 becomes variable.

[0043] The second bundling member 50A has an inner diameter equivalent to the outer diameter d (see FIG. 2) of the wire harness 30, and is configured to allow deformation along the radial direction of the wire harness 30. That is, the second bundling member 50A is wound around a plurality of wires W in a state where the wire harness 30 can be elastically deformed. Note that FIG. 17 shows a cross-sectional shape at the time of insertion (elastic deformation) into the slit 20 of the deformable bundling portion 32 bundled by the second bundling member 50A.

[0044] As described above, in the wire harness WH of this modification, the second bundling member 50A has an inner diameter equivalent to the outer diameter d of the wire harness 30, and is configured to allow deformation along the radial direction of the wire harness 30. With this configuration, the wire harness WH can, for example, allow deformation and displacement of the wire harness 30 by the second bundling member 50A, and thus the workability of the attachment operation of the wire harness WH can be improved.

[0045] In the above-described embodiments and modifications, the attachment member 10A is exemplified as being constituted by the body member 10 that constitutes the framework of the vehicle 100, but is not limited to this example. For example, it may be constituted by a metal exterior member that regulates the routing path of the wire harness 30. Also, in the above-described embodiments and modifications, the case where the slit 20 is provided in the upper wall 11a of the body member 10 (attachment member 10A) is exemplified, but is not limited to this example. For example, it may be provided in the side wall 11c located on the vehicle interior space side of the pair of side walls 11c and 11d. In this case, the side wall 11c is an example of the first wall portion.

[0046] In the above-described embodiment and the above-described modification, the case where the slit 20 is provided to extend along the axial direction X with respect to the outer wall 11 of the body member 10 has been illustrated. However, the present invention 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, by providing the second portion across the upper wall 11a and the side wall 11c on the vehicle interior space side of the outer wall 11, the bundling posture maintaining portion 31 of the wire harness 30 can be drawn out from the side wall 11c.

[0047] As described above, the embodiments and modifications of the present invention have been illustrated. However, the above-described embodiments and modifications are merely examples and are not intended to limit the scope of the invention. The above-described embodiments and modifications can be implemented in various other forms, and various omissions, replacements, combinations, and changes can be made without departing from the gist of the invention. Further, each configuration, shape, etc. of the specifications (structure, type, direction, form, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be appropriately changed and implemented.
