Detailed Description

(embodiment )

Fig. 1 is an explanatory view showing a portion of a vehicle 90 to which the support structure for a harness with a support member is applied, fig. 2 is a perspective view showing a harness 10 with a support member and a support structure thereof according to embodiment , and fig. 3 is a cross-sectional view showing the harness 10 with a support member and a support structure thereof according to embodiment .

The support structure for a wire harness according to the present invention is configured to support a wire harness 12 on a rod-shaped member 60 using a support member 40. In more detail, the wire harness 12 is supported by the support member 40. The support member 40 is supported by the rod member 60. Thus, the wire harness 12 is supported by the rod member 60 via the support member 40. For example, the wire harness 12 is transported to an assembly plant of a vehicle so that the support member 40 is attached thereto, that is, the wire harness 10 with the support member is attached thereto, and the support member 40 of the wire harness 10 with the support member is supported by the rod-shaped member 60 at the assembly plant. However, the wire harness 12 and the support member 40 may be transported in different forms to a vehicle assembly plant where the wire harness 12 is supported by the support member 40 and the support member 40 is supported by the rod-like member 60. In this case, the support member 40 may be supported by the rod-shaped member 60, and then the wire harness 12 may be supported by the support member 40.

Examples of the rod-shaped member 60 include a reinforcement, a frame of a vehicle body, and the like. Here, an example will be described in which the wire harness 12 is supported by a reinforcement, which is a rod-shaped member 60 having a cylindrical peripheral surface. In particular, as shown in fig. 1, the rod-shaped member 60 will be described as a reinforcement disposed on the rear surface side of the instrument panel 92 (between the instrument panel 92 and the dash panel 94) in the vehicle 90.

Fig. 4 is a perspective view showing the wire harness 12 according to the th embodiment.

The wire harness 12 includes a sheet 30 and the electric wire 14 arranged on the sheet 30. The wire 14 is stitched to the sheet 30 by thread 38. Thereby, the electric wire 14 is fixed to the sheet 30.

The sheet 30 is not particularly limited as long as it can be bent and deformed along the outer periphery of the support member 40 and can fix the electric wire 14, and the material and the manufacturing method thereof are not particularly limited, and for example, the sheet 30 may be made of synthetic resin, metal, natural fiber such as wool or cotton, or a combination thereof, and for example, a nonwoven fabric, a woven fabric, a knitted fabric, or the like may be considered as the sheet 30, and for example, in the case where the sheet 30 is made of synthetic resin, it may be formed to have a cross section of by extrusion molding or the like, and for example, in the case where the sheet 30 is made of metal, it may be formed to be foil by rolling or the like.

In the example shown in fig. 4, the sheet 30 is formed in a rectangular shape, but the sheet is not limited to this. For example, the sheet 30 may be formed in an L shape. The sheet 30 having such a shape is suitable for the case where the electric wire 14 is arranged in a bent state. Further, the sheet 30 may be formed in a T-shape, an X-shape, or the like. The sheet 30 having such a shape is suitable for a case where the electric wire 14 is branched halfway. That is, the sheet 30 may be formed in a shape corresponding to the arrangement form of the electric wire 14.

The sheet 30 may be used for purposes other than fixing the electric wire 14 and supporting the fixed electric wire 14 on the supporting member 40. Examples of the applications include protection, heat dissipation, sound insulation, and tension members.

The wires 14 include at least 1. Here, the electric wire 14 includes a plurality of (3 in the example shown in fig. 2). The plurality of wires 14 are arranged in a flat state with respect to the sheet 30. More specifically, the wires 14 are fixed in a state of being arranged in parallel while being separated from each other. However, the plurality of electric wires 14 may be fixed in a bundled state. Here, an insulated wire including a core wire and an insulation coating covering the core wire is used as the wire 14. The core wire is formed of a conductive material such as copper or aluminum. The core wire may be a single wire or a twisted wire. The insulating coating may be formed by extrusion molding of a resin or the like on the outer periphery of the core wire, or may be formed by baking of a varnish or the like applied to the outer periphery of the core wire. However, bare wires may also be used as wires.

The portion of the wire harness 12 disposed along the rod-shaped member 60 is a support target. In the example shown in fig. 4, the entire wire 14 is fixed to the sheet 30. In this case, as shown in fig. 2, the entire electric wire 14 is supported by the rod-like member 60. However, the case where the wire 14 is integrally fixed to the sheet 30 is not an essential structure. It is needless to say that the entire electric wire 14 is supported by the rod-like member 60.

Here, in the example shown in fig. 4, all of the 3 electric wires 14 are fixed to the sheet 30. However, in the case where the wire harness 12 includes a plurality of electric wires 14, the electric wires 14 that are not fixed to the sheet 30 may be included.

In the example shown in fig. 4, all of the 3 wires 14 are connected to the same connector 16. However, where the wiring harness 12 includes a plurality of wires 14, wires 14 connected to different connectors 16 may be included. For example, a terminal connected to an end of the wire 14 is inserted into and connected to a cavity 19 formed in the body portion 18 of the connector 16. The terminal is connected to the electric wire by, for example, crimping, pressure welding, or the like.

In the example shown in fig. 4, the electric wire 14 is arranged linearly. However, the electric wire 14 may be arranged in a bent manner. When the wire harness 12 includes a plurality of wires 14, the wires 14 arranged in a straight line and the wires arranged in a bent line may coexist. In this case, a plurality of wires 14 may be branched on the sheet 30. In this case, a plurality of wires 14 may be disposed at branching positions on the sheet 30 so that there is a wire crossing another wire 14.

In the example shown in fig. 4, the electric wire 14 is disposed at a position close to the center in the width direction with respect to the sheet 30. However, the path for disposing the electric wire 14 on the sheet 30 is not limited to the above path. For example, the electric wire 14 may be arranged at a position close to the end in the width direction with respect to the sheet 30. Also for example, the wires 14 may extend obliquely with respect to the sheet 30.

The end of the wire 14 is assembled to the connector 16. In a state where the present wire harness 12 is arranged at a position to be arranged in a vehicle or the like, the connector 16 is connected to the connector 16 mounted on various electrical devices of the vehicle or the like. Thus, the present harness 12 is used as a wire for electrically connecting various electrical devices mounted on a vehicle or the like.

Here, the connector 16 is also fixed to the sheet 30, and in particular, the connectors 16 connected to both ends of the electric wire 14 are fixed to the sheet 30 here, however, it is not essential that the connectors 16 be fixed to the sheet 30, and in this case, there may be a case where the portion of the connector 16 overlaps with the edge portion of the sheet 30 and the connector 16 is not fixed to the sheet 30, except for a case where the connector 16 cannot be fixed to the sheet 30 because the connector 16 is provided at the end portion of the electric wire 14 extending from the sheet 30.

In the example shown in fig. 2, the wires 14 are arranged on main surface sides of the sheet 30, and the sheet 30 has the main surface on which the wires 14 are not arranged facing the support member 40 side, however, the sheet 30 may have the main surface on which the wires 14 are arranged facing the support member 40 side, in this case, the wires 14 are sandwiched between the sheet 30 and the support member 40, and the wires 14 may be arranged so as to move from main surface sides of the sheet 30 to another main surface sides in the middle.

As a method of sewing the electric wire 14, a sewing machine may be used, and of course, the electric wire 14 may be sewn by hand, and in the case of sewing by a sewing machine, for example, a case where an upper thread and a lower thread in the sewing machine are separately prepared from the electric wire 14, or a case where the electric wire 14 is used for sides of the upper thread and the lower thread in the sewing machine, and the like are conceivable.

However, the fixing method of the electric wire 14 to the sheet 30 is not limited to the sewing. For example, the electric wire 14 may be fixed to the sheet 30 by welding, as in the wire harness 112 shown in fig. 5. In this case, the sheet 30 may be any sheet as long as the electric wire 14 can be welded. As the welding method, ultrasonic welding, laser welding, thermal welding, or the like may be used. Also, for example, the electric wire 14 may be fixed to the sheet 30 by an adhesive, an adhesive tape, or the like. The sheet 30 may be configured to have 2 or more layers, and the electric wire 14 may be fixed by being sandwiched between the 2 layers of the sheet 30.

Fig. 6 is a perspective view showing the supporting member 40 according to the th embodiment.

The support member 40 is a member for supporting the wire harness 12 to the rod-shaped member 60, the support member 40 includes the fitting portion 42, and the support member 40 includes the locking protrusion 44 as a support portion, the support member 40 is formed by injection molding or the like using a resin or the like as a material, for example, into a shape including the fitting portion 42 and the locking protrusion 44.

The fitting portion 42 is a portion formed so as to be able to fit to the outer peripheral portion of the rod-shaped member 60, more specifically, the fitting portion 42 is formed in a partial cylindrical shape that is partially open in the circumferential direction , here, the fitting portion 42 is formed in a partial cylindrical shape (cross-sectional C shape) that is partially open in the circumferential direction and has an extension that is half as large as in the circumferential direction, in other words, the fitting portion 42 is formed in a shape having an inner peripheral portion with a radius of curvature that is approximately the same as the radius of curvature of the outer peripheral portion of the rod-shaped member 60 in an angular range greater than 180 degrees.

The inner peripheral shape of the fitting portion 42 is formed to be the same as the outer peripheral shape of the rod-like member 60 or smaller (slightly smaller here) than the outer peripheral shape of the rod-like member 60. The opening of the fitting portion 42 is set smaller than the diameter of the rod-like peripheral member. The fitting portion 42 is formed to be elastically deformable so as to expand the opening portion. More preferably, the fitting portion 42 may be configured to have an inner peripheral shape that is not detached by the wire harness 12 and its own weight and is set to be small enough to be unable to rotate around the central axis of the rod-shaped member 60, with the rod-shaped member 60 being disposed inside.

When the rod-like member 60 is inserted into the fitting portion 42 through the opening portion, the opening portion is elastically deformed and expanded, and when the rod-like member 60 is disposed on the rear surface side, the fitting portion 42 is brought into a state of holding the outer peripheral portion of the rod-like member 60 by a force of elastically returning to the original shape.

The wire harness 12 supported by the support member 40 is supported so as to extend along the rod-shaped member 60 by fitting the fitting portion 42 of the wire harness 10 with the support member to the outer periphery of the rod-shaped member 60. The support member 40 and the wire harness 10 with the support member may be fitted to the rod-shaped member 60 from the side, or may be fitted to the rod-shaped member 60 from the top-bottom direction (of course, may be fitted to the rod-shaped member 60 from another direction). That is, the support member 40 and the wire harness 10 with the support member can be maintained in a posture in which the wire 14 is fitted to the rod-shaped member 60 in a direction in which the fitting is easy and the space for arranging the wire harness 12 can be secured.

The support structure of the support member 40 and the wire harness 12 uses at least -side support portions formed in the sheet material 30 and the support member 40, the support portions support the sheet material 30 arranged along the outer periphery of the fitting portion 42 at a fixed position with respect to the fitting portion 42, and specifically, the locking protrusion portions 44 are formed as the support portions.

The locking projection 44 is formed on the support member 40. The locking protrusion 44 protrudes from the fitting portion 42 toward the outer circumferential side. The locking protrusion 44 is locked in a state of penetrating the sheet 30. More specifically, the locking projection 44 includes a column portion 45 and a locking projection 46. The column portion 45 is provided so as to protrude outward from the outer peripheral surface of the fitting portion 42. The locking projection 46 is provided at the front end of the column portion 45. The locking projection 46 is formed to project radially outward from the column portion 45. The sheet material 30 is supported by the support member 40 by causing the locking projection 46 to penetrate the sheet material 30 and causing the locking projection 46 to be caught by the sheet material 30. In the example shown in fig. 6, the locking projection 46 is formed in a tapered shape such as a cone shape, but the invention is not limited thereto. The locking projection 46 may be formed in a flat plate shape such as a disc shape.

Here, as shown in fig. 4, it is preferable that a hole 32 through which the locking projection 46 can be inserted is formed in advance in the sheet material 30. This eliminates the need to pass the locking projection 46 through a portion of the sheet 30 where the hole 32 is not provided, and the shape of the locking projection 46 can be simplified. The hole 32 may be formed in a circular shape, a slit shape, or the like.

The support portions (here, the locking projections 44) are provided at a plurality of locations separated in the circumferential direction. In particular, the support portions (here, the locking projections 44) are provided so as to be able to support both circumferential end portions of the sheet 30. This makes the circumferential end of the sheet 30 less likely to rattle. The support portions (here, the locking projections 44) are provided at a plurality of locations along the longitudinal direction of the rod-shaped member 60. In particular, the support portions (here, the locking projections 44) are provided so as to be able to support both longitudinal end portions of the sheet 30. This makes the longitudinal end of the sheet 30 less likely to wobble. Therefore, in this case, 4 corners of the rectangular sheet 30 are supported by the support member 40 via support portions (here, the locking projections 44).

In this case, in the example shown in fig. 2, all of the 4 support portions are the locking projections 44. However, the support portion may be configured differently from the locking projection 44. The supporting portion having a different configuration from the locking projection 44 will be described in detail later.

According to the above-described aspect, the support portion (here, the locking protrusion portion 44) can support the wire harness 12 arranged along the outer periphery of the fitting portion 42 at a fixed position with respect to the fitting portion 42. Further, for example, the support member 40 can be supported by the rod-like member 60 in a state where the sheet 30 of the wire harness 12 is supported at a fixed position with respect to the support member 40. This is suitable for a case where the wire harness 12 is supported by the rod member 60 in a flat manner (specifically, with a small undulation with respect to the outer periphery of the rod member 60).

At this time, since the electric wire 14 is fixed to the sheet 30 and the sheet 30 is fixed to the support member 40, the electric wire 14 is supported at a fixed position with respect to the support member 40 and is hard to move. In particular, the electric wire 14 is held so as not to move relative to the fitting portion 42. This can suppress occurrence of vibration, friction, and the like in the electric wire 14. Further, the state in which the electric wire 14 is spread along the outer periphery of the fitting portion 42 is easily maintained, and thus the state in which the electric wire 14 is spread along the outer periphery of the rod-like member 60 is easily maintained even in the region adjacent to the supporting member 40 in the longitudinal direction of the rod-like member 60 in the state in which the wire harness 10 with the supporting member is supported by the rod-like member 60.

Further, the sheet 30 can be easily supported by the support member 40 by the locking projection 44. Further, the sheet 30 is easily supported at a fixed position with respect to the support member 40.

Further, since the electric wire 14 is fixed to the sheet 30 by sewing or welding, the flat wire harness 12(112) can be easily obtained.

(second embodiment)

Next, a description will be given of a wire harness with a support member and a support structure thereof according to a second embodiment, fig. 7 is a cross-sectional view showing the wire harness with a support member 210 and the support structure thereof according to the second embodiment, fig. 8 is a bottom view showing the wire harness 212 according to the second embodiment, and in the description of the present embodiment, components similar to those described so far are denoted by , and the description thereof will be omitted.

In the wire harness with a support member 210 of the second embodiment, the structure of the support portion of the portion is different from the locking protrusion 44, which is the structure of the support portion in the wire harness with a support member 10 of the embodiment.

Here, the support member 240 is provided with the locking projection 44 as 2 support portions located on the end side in the circumferential direction among the 4 support portions, and the sheet 230 is provided with the recess 34 as 2 support portions located on the other end side in the circumferential direction among the 4 support portions.

The concave portion 34 is formed on the inner peripheral side of the sheet 230. The recess 34 is formed so that an end (here, a circumferential end) of the fitting portion 42 can be inserted. At this time, the recess 34 is formed in a bag shape, i.e., in a shape having a bottom 35.

The recess 34 is formed as follows, for example. That is, first, the circumferential end of the sheet 230 is folded back. Then, the edge of the portion where the folded portion and the original portion overlap is fixed. Thus, as shown in fig. 7, the recess 34 is formed in a bottomed bag shape. However, the method of forming the recess 34 is not limited to the above method. For example, a sheet different from the sheet 230 to which the electric wire 14 is fixed may be prepared, and the sheet may be overlapped with the sheet 230 and then three edge portions of the sheet may be fixed to the sheet 30, thereby forming the concave portion 34. The edge portion may be fixed by sewing, welding, or adhesion with an adhesive or a double-sided tape.

Then, the locking projection 44 of the support member 240 is inserted into the hole 32 of the sheet material 230, the circumferential end of the sheet material 230 is supported by the support member 240, and the other circumferential end of the sheet material 230 is supported by the support member 240 by inserting the edge of the fitting portion 42 of the support member 40 on the side (the other end side) where the locking projection 44 is not provided into the recess 34.

However, the recess 34 may have a cylindrical shape without the bottom 35. Such a recess is formed, for example, by forming the recess into a bottomed bag shape by the method involving folding back described above, and then forming a slit in a portion of the bag corresponding to the bottom 35. For example, when the sheet piece is overlapped on the sheet 230 and the edge portions are fixed, only two edge portions which are portions extending in the circumferential direction are fixed.

When the recess 34 has a bottom, the front end of the fitting portion 42 of the support member 240 reaches the bottom 35 of the recess 34, and thereby the sheet 230 can be prevented from being displaced from the support member 240 by steps in the circumferential direction, and in the other , when the recess 34 has a shape without the bottom 35, it is easy to cope with a plurality of types of support members 240 having different lengths of the fitting portion 42 by the size of 1 type of sheet 230.

The case where the recess 34 is formed so as to be able to be inserted into the circumferential end of the fitting portion 42 of the support member 240 has been described, but this case is not essential. The recess 34 may be formed so as to be inserted into the longitudinal end of the support member 240. In this case, the concave portion is provided at a longitudinal end of the sheet.

According to this embodiment, the sheet 230 can be easily supported by the support member 240 by inserting the fitting portion 42 into the recess 34. In particular, the sheet 230 is easily supported at a fixed position with respect to the support member 240 by forming the recess 34 into a bag shape.

When the wire harness 210 with the support member of the present embodiment is supported by the rod-shaped member 60, as shown in fig. 7, the portion of the sheet 230 that constitutes the concave portion 34 (here, the folded portion of the sheet 230) is sandwiched between the support member 240 and the rod-shaped member 60. Thereby, the circumferential end of the sheet 230 is difficult to shake.

(third embodiment)

Next, a description will be given of a wire harness with a support member and a support structure thereof according to a third embodiment, fig. 9 is a front view showing the wire harness with a support member 310 and the support structure thereof according to the third embodiment, fig. 10 is a plan view showing the wire harness 312 according to the third embodiment, and fig. 11 is a perspective view showing the support member 340 according to the third embodiment, and in the description of the present embodiment, constituent elements similar to those described so far are denoted by symbols, and the description thereof will be omitted.

In the wire harness with a support member 310 of the third embodiment, the structure of the support portion of the portion is different from the locking protrusion 44, which is the structure of the support portion in the wire harness with a support member 10 of the embodiment.

Here, the support member 340 is provided with the locking projection 44 as 2 support portions located on the end side in the circumferential direction among the 4 support portions, and the support member 340 is provided with the connector locking portion 48 as 2 support portions located on the other end side in the circumferential direction among the 4 support portions.

More specifically, in the harness 312, the connector 316 is positioned at an end portion (here, a circumferential end portion) of the sheet member 330, the connector locking portion 48 is provided so as to protrude from the fitting portion 42 toward the outer circumferential side, the connector 316 is locked at the connector locking portion 48, as a locking structure of the connector 316, a structure in which the locking piece 50 is locked to the locking recess 23 provided at the outer circumferential side of the body portion 18 of the connector 316, which is also referred to as a so-called box structure or the like, may be employed, and it is noted that, in the example shown in fig. 9, the locking piece 50 is inserted into the locking recess 23 from the side opposite to the side where the electric wire 14 is inserted into the cavity 19, but may be inserted from the side where the electric wire 14 is inserted into the cavity 19, and more specifically, as shown in fig. 10, 2 parallel locking pieces 21 out of the box portions 20 formed in an H shape are protruded from the outer circumferential side of the body portion 18 of the connector 316, and the box portions 22 formed in an H shape are protruded from the circumferential direction between the body portion 18 of the connecting piece 21 and the connecting end portion 22, which the connecting piece 21 and the connecting end portion 49, which the connecting piece comes to function is included between the body portion 18.

When the connector 316 is locked to the connector locking portion 48, as shown in fig. 9, an end portion (here, a circumferential end portion) of the sheet member 330 is sandwiched between the connector 316 and the fitting portion 42. Thereby, the circumferential end of the sheet 330 is difficult to shake. For example, the length dimension of the base end portion 49 of the connector locking portion 48 is made shorter than the sum of the thickness dimension of the sheet material 330 and the thickness dimension of the connecting piece 22 of the connector locking portion 48, whereby the end portion of the sheet material 330 is sandwiched between the connector 16 and the fitting portion 42. However, the end of the sheet 330 may not be sandwiched between the connector 316 and the fitting portion 42.

Although the case where the connector locking portion 48 is provided at the circumferential end of the support member 340 has been described above, this case is not essential. The connector locking portion 48 may be provided at the longitudinal end of the support member 340.

According to this aspect, the sheet 330 can be easily supported by the support member 340 by locking the connector 316 to the connector locking portion 48. Further, since the end of the sheet 330 is sandwiched between the connector 316 and the fitting portion 42, the end of the sheet 330 is less likely to shake.

(fourth embodiment)

Next, a wire harness with a support member and a support structure thereof according to a fourth embodiment will be described, fig. 12 is a sectional view showing the wire harness with a support member 410 and a support structure thereof according to the fourth embodiment, fig. 13 is a perspective view showing the support member 440 according to the fourth embodiment, and fig. 14 is a perspective view showing the rod-shaped member 460 according to the fourth embodiment, and in the description of the present embodiment, components similar to those described so far are denoted by , and the description thereof will be omitted.

Here, the wire harness 410 with the support member is positioned and supported at a fixed position with respect to the rod-like member 460 by the positioning protrusion 52 provided to the support member 440.

More specifically, the positioning protrusion 52 protrudes from the fitting portion 42 toward the inner circumferential side. In response to this, the hole 62 capable of receiving the positioning protrusion 52 is formed in the rod-like member 460. When the rod-like member 460 has a cylindrical shape, the hole 62 may be a through hole.

Here, the hole 62 is formed larger than the positioning protrusion 52, and the positioning protrusion 52 and the hole 62 are formed so as not to be locked. Therefore, the positioning projection 52 is easily accommodated in the hole 62. However, the positioning projection 52 may be engaged with the hole 62, and for example, the positioning projection 52 may be pressed into the hole 62.

In the example shown in fig. 12, the positioning projecting portion 52 is formed in a truncated cone shape, and the hole 62 is formed in a cylindrical shape, and at least of the configuration in which the positioning projecting portion 52 is formed in a tapered shape and the configuration in which the hole 62 is formed in a shape that gradually expands toward the opening may be provided, whereby the positioning projecting portion 52 is easily accommodated in the hole 62.

Here, the positioning protrusion 52 is provided protruding from the inner circumferential surface near the circumferential center of the fitting portion 42. However, the positioning protrusion 52 may be provided to protrude from the inner circumferential surface of the fitting portion 42 on the circumferential end side. In particular, the positioning projection 52 may be provided at the same position as the support portion (here, the locking projection 44) in the circumferential direction.

A plurality of positioning protrusions 52 are provided at intervals in the longitudinal direction. This enables the positioning state to be maintained more reliably. In particular, after the positioning protrusion 52 is housed in the hole 62 of the rod-shaped member 460, the positioning state is stable even when the fitting portion 42 on the end portion side where there is no positioning protrusion is covered on the rod-shaped member 460. The positioning protrusion 52 is provided at a position different from the support portion (here, the locking protrusion 44) in the longitudinal direction, but may be provided at the same position as the support portion (here, the locking protrusion 44).

According to this embodiment, when the support member 440 is attached to the rod-shaped member 460, the support member 440 and the rod-shaped member 460 can be easily positioned using the positioning protrusion 52. Further, since the positioning projection 52 is received in the hole 62 after the support member 440 is attached to the rod-like member 460, the support member 440 is less likely to be displaced in the longitudinal direction and the circumferential direction with respect to the rod-like member 460, and the positioning state is easily maintained.

( -modified example of the fourth embodiment)

Fig. 15 is an explanatory diagram showing a modification of the wire harness 12.

The description has been made so far of the case where the entire portion of the wire harness 12 fixed to the sheet 30 is flat, but this need not be the case, and as shown in fig. 15, a case where the portion of the sheet 530 is rounded in the wire harness 512 is also conceivable.

Fig. 16 is an explanatory diagram illustrating another modification of the wire harness 12.

The case where the entire electric wires 14 are fixed to the sheet 30 has been described, but this need not necessarily be the case, as shown in fig. 16, it is also conceivable that there is a portion of the wire bundle 612 that is not fixed to the sheet 30 at the portion , and thus, when the portion of the electric wires 14 is not fixed to the sheet 30, the electric wires 14 are easily bent and deformed at the portion that is not fixed to the sheet 30, as shown in fig. 16, it is conceivable that the portion of the electric wires 14 that is not fixed to the sheet 30 is formed into a bundle, as shown in fig. 16, whereby the electric wires 14 are more easily bent and deformed, it is also possible that the portions of the plurality of electric wires 14 that are formed into a bundle are bundled by the bundling member 28, and as the bundling member 28, an adhesive tape, a bundling tape, or the like.

Fig. 17 is an explanatory diagram showing a modification of the wire harness 10 with the support member.

The description has been made so far of the case where the fitting portion 42 of the support member 40 is present in the entire longitudinal direction of the sheet 30, but this is not an essential configuration, and as shown in fig. 17, in the wire harness 710 with a support member, the fitting portion 742 of the support member 740 may be present only in the region of the portion in the longitudinal direction of the sheet 30, in the example shown in fig. 17, 2 support members 740 each having the fitting portion 742 formed shorter than the sheet 30 are located at both ends in the longitudinal direction of the sheet 30, and therefore, the support member 740 is not present in the middle portion in the longitudinal direction of the sheet 30, and in this case, it is conceivable that the sheet 30 is directly wound around the bar-shaped member 60.

Although the case where the 4 corners of the rectangular sheet 30 are supported by the support portions has been described above, this case is not essential. There may be a case where 1 corner, 2 corners, or 3 corners of the rectangular-shaped sheet 30 are supported by the support portion. In this case, the end portion of the sheet 30 not supported by the support portion may be sandwiched between the rod-like member 60 and the fitting portion 42, for example.

The modifications described above can also be applied to the wire harness with the support member and the support structure thereof according to the following fifth to seventh embodiments.

(fifth embodiment)

Next, a description will be given of a wire harness with a support member and a support structure thereof according to a fifth embodiment, fig. 18 is a sectional view showing the wire harness with a support member 810 and the support structure thereof according to the fifth embodiment, fig. 19 is a perspective view showing the support member 840 according to the fifth embodiment, fig. 20 is a front view showing the support member 840 according to the fifth embodiment, an imaginary line in fig. 20 shows a state where the support member 840 is elastically deformed when being assembled to the rod-shaped member 460, fig. 21 is a plan view showing the support member 840 according to the fifth embodiment, fig. 22 is a side view showing the support member 840 according to the fifth embodiment, fig. 23 is a perspective view showing the band member 70 used for the wire harness with a support member 810 according to the fifth embodiment, fig. 24 is an explanatory view showing a state where the wire harness with a support member 810 according to the fifth embodiment is manufactured, and in the description of the present embodiment, the same constituent elements as those described so far are denoted by the same reference numerals as , and description thereof is omitted.

Here, the harness 812 is supported by the support member 840 using the band member 70. Therefore, the wire harness with support member 810 and the support structure thereof according to the fifth embodiment further include the strap member 70. Here, the shapes of the wire harness 812 and the support member 840 are also changed from the shapes of the wire harness and the support member described above. The rod member 460 is the same as the rod member 460 shown in fig. 13. Therefore, here, the hole 62 is also formed in the rod-like member 460. The positional relationship among the support member 840, the wire harness 812, and the rod member 460 is the same as the positional relationship among the support member 740, the wire harness 12, and the rod member 60 in the wire harness 710 with a support member.

When the wire harness 812 is viewed, the electric wire 14 is sandwiched by the 2 sheets 30 to be formed flat as a whole. At this time, the electric wire 14 is not fixed to the sheet 30. Therefore, the electric wires 14 are maintained in a flat state by causing the electric wires 14 to be sandwiched by the 2 sheets 30 and causing the wire harness 812 to be sandwiched by the support member 840 and the belt member 70. However, the wire 14 may be fixed to the sheet 30. Also, in the example shown in fig. 18, the electric wires 14 are arranged in 2 layers, but this case is not a necessary structure. The wires 14 may be arranged in 1 layer or 3 or more layers.

The 2 sheets 30 are fixed directly or indirectly. Here, both side edge portions of the 2 sheets 30 are directly fixed to each other. Thereby, the electric wire 14 is surrounded by the 2 sheets 30. The fixing means is not particularly limited, and various fixing means can be used. As the fixing means, for example, joining or welding with an adhesive, a double-sided adhesive tape, or the like, mechanical fixing with a stopper member such as a clip, or the like can be used. As a case of indirectly fixing the 2 sheets 30, for example, a case of fixing the wires 14 to the 2 sheets 30 and fixing the wires 14 to each other may be considered.

The fitting portion 842 of the support member 840 includes a body 842a and a fitting piece 843.

The body 842a is formed in a semi-elongated cylindrical shape in which a cylinder having an oblong cross section is divided into halves, specifically, the body 842a includes a semi-cylindrical portion 842b capable of covering a half-circumference portion of the rod-shaped member 460 and an extending portion 842c extending straightly in a tangential direction from each of both end portions of the semi-cylindrical portion 842b, and in the example shown in fig. 18, the extending dimension of the extending portion 842c is set smaller than the radius of curvature of the semi-cylindrical portion 842 b.

The fitting pieces 843 are formed on the inner surfaces of the 2 extending portions 842c, and the inner surfaces of the fitting pieces 843 are formed in a curved surface shape, the inner surfaces of the fitting pieces 843 are formed to have a radius of curvature equal to the radius of curvature of the semi-cylindrical portion 842b, and the fitting pieces 843 are formed to have a size capable of covering -th of the circumference of the rod-shaped member 460, however, the area covered by the fitting pieces 843 with the rod-shaped member 460 is not limited thereto, and the fitting pieces 843 may be formed to fit the rod-shaped member 460 with the semi-cylindrical portion 842b, and may cover an area larger than -eighth of the rod-shaped member 460, or may cover an area smaller than -eighth of the circumference.

Here, the space between the distal ends of the fitting pieces 843 is an opening portion of the fitting portion 842, and the rod-like member 460 can be inserted into the inner circumferential side of the support member 840 through the opening portion. More specifically, in the support member 840, the size of the opening portion is set smaller than the diameter of the rod-like member 460. And, the opening portion can be elastically deformed to have a size equal to the diameter of the rod-like member 460. The outer surface side of the distal end portion of each fitting piece 843 is a guide surface 843a formed in a tapered shape. When the rod-shaped member 460 is inserted into the inner peripheral side of the support member 840 through the opening portion, the support member 840 is guided to be elastically deformed in a direction to increase the opening portion by the rod-shaped member 460 abutting against the guide surface 843a, as shown by the imaginary line in fig. 20.

Here, a description will be given of a case where the supporting member 840 is an -body molded article using a mold, in this case, when the fitting piece 843 is provided on the inner surface of the extending portion 842c, the through hole 842d for mold extraction is formed in the body portion 842a, the through hole 842d is provided in the semi-cylindrical portion 842b at a position overlapping with the fitting piece 843 when viewed from the extending direction of the extending portion 842c (when viewed from the top as shown in fig. 21), and in this case, the dimension of the fitting piece 843 in the axial direction is formed smaller than the dimension of the body portion 842a in the axial direction, and the fitting piece 843 is formed in the center of the extending portion 842c in the axial direction, whereby the decrease in rigidity of the supporting member 840 caused by the formation of the through hole 842d can be suppressed.

Here, a rib 842e extending in the circumferential direction is formed on the outer surface of the body 842 a. A plurality of (4 in this case) ribs 842e are provided at intervals in the axial direction of body 842 a. By providing the rib 842e, the rigidity of the support member 840 can be improved. The number, shape, size, interval, and the like of the ribs 842e may be appropriately set.

The support member 840 is provided with a support portion including, on each end side in the circumferential direction of the support member 840, an -th locking portion and a second locking portion formed so as to be capable of locking the belt member 70, the -th insertion portion 854 and the second insertion portion 856 formed so as to be capable of inserting and locking the belt member 70 are provided as the -th locking portion and the second locking portion, respectively, in the example shown in fig. 18, the -th locking portion and the second locking portion include a structure capable of locking the belt member without inserting, for example, a structure including a protrusion or the like that is locked by penetrating a plurality of holes formed in the longitudinal direction of the belt member.

The th insertion portion 854 is formed so as to be able to insert a later-described band portion 72 of the band member 70 and not to be able to insert a later-described regulating portion 74 of the same band member 70. specifically, the th insertion portion 854 is provided on the outer surface of the main body portion 842a on the circumferential end side.a th insertion hole 854 is formed in the th insertion portion 854, the cross section of the th insertion hole 854h is formed so as to be the same as or larger than (slightly larger than) the band portion 72, and the th insertion hole 854h is formed so as to extend in the extending direction of the extending portion 842 c.

The second insertion portion 856 is formed with a band locking portion 857 that is engageable with an uneven portion 73, described later, of the band portion 72 such that the band portion 72 can be inserted in orientations and cannot be inserted in orientations, specifically, the second insertion portion 856 is provided on an outer surface of the main body portion 842a on the other end side in the circumferential direction, the second insertion hole 856h is formed in the second insertion portion 856, the cross section of the second insertion hole 856h is formed larger than the band portion 72 and the insertion hole 854h, the second insertion hole 856h is formed to extend in the extending direction of the extending portion 842c, and the band locking portion 857 is formed to protrude from the inner peripheral surface of the second insertion hole 856h into the second insertion hole 856 h.

Here, the insertion hole 854h of the th insertion part 854 and the second insertion hole 856h of the second insertion part 856 are provided between the central 2 ribs 842e of the 4 ribs 842e, and the interval between the central 2 ribs 842e is formed to be the same as or larger than the width of the tape part 72, whereby the tape part 72 can be disposed between the central 2 ribs 842 e.

The band member 70 is inserted and locked to the th insertion portion 854 and the second insertion portion 856 with the wire harness 812 sandwiched between the band member and the outer peripheral surface of the support member 840, and the band member 70 includes a band portion 72 and a regulating portion 74 provided at the base end of the band portion 72.

The band portion 72 is formed in a band shape, the band portion 72 is formed with an uneven portion 73 to which the band locking portion 857 can be locked, here, the uneven portion 73 is formed on main surfaces of the band portion 72, and the uneven portion 73 is locked to the band locking portion 857 by the second insertion portion 856 in a state where the band portion 72 is inserted through the th insertion portion 854 and the second insertion portion 856.

Here, the uneven portion 73 of the belt portion 72 is locked with the belt locking portion 857 as follows.

That is, here, the concave-convex portion 858 is also formed on the contact surface of the belt locking portion 857 with the concave-convex portion 73 formed on the belt portion 72, and here, for example, at least sides (here, the concave-convex portion 858 of the belt locking portion 857) of the concave-convex portion 858 of the belt locking portion 857 and the concave-convex portion 73 of the belt portion 72 are provided with a vertical surface perpendicular to the insertion direction and an inclined surface inclined with respect to the insertion direction, and further, when the belt portion 72 is inserted into the second insertion portion 856, insertion can be advanced by steps by the contact of the inclined surface, and when the belt portion 72 is to be pulled out from the second insertion portion 856, the belt locking portion 857 can be locked to the concave-convex portion 73 of the belt portion 72 so that the belt portion 72 can be inserted toward directions and cannot be inserted toward the other directions.

At this time, the concave and convex portions 858 of the belt locking portion 857 can be selectively locked to the concave and convex portions 73 of the belt portion 72. Thereby, the belt locking portion 857 can be locked at a desired position with respect to the belt portion 72. At this time, if the distal end portion 72a of the strap portion 72 that has passed through the second insertion portion 856 is pulled with a predetermined force, for example, the force with which the harness 812 is sandwiched between the strap member 70 and the support member 840 can be set to a predetermined force.

The distal end portion 72a of the band portion 72 that has passed through the second through-hole 856 may be cut out or may not be cut out, as necessary. The cut-out is preferable because the protruding dimension of the tip end portion 72a of the band portion 72 that has passed through the second through portion 856 may interfere with surrounding members of the vehicle 90.

The cross section of the regulating portion 74 is formed larger than the cross section of the band portion 72, so that in a state where the base end of the band portion 72 is inserted through the -th insertion portion 854, the regulating portion 74 abuts against the peripheral edge of the -th insertion hole 854h in the -th insertion portion 854, and insertion of the band portion 72 in the step to the -th insertion hole 854h is regulated.

Here, the support member 840 is further provided with a positioning protrusion 52 and a belt extending direction restricting portion 859. The positioning protrusion 52 is the same as the positioning protrusion 52 of the fourth embodiment, and therefore, the description thereof is omitted.

Specifically, the belt extending direction regulating portion 859 is provided on the outlet side (here, the outside of the outlet) of the th insertion hole 854h, the outer surface of the belt extending direction regulating portion 859 is an inclined surface which is continuous with the surface on the inner peripheral side of the th insertion hole 854h and is inclined toward the outer peripheral side with respect to the axial direction of the th insertion hole 854h, and the belt portion 72 having passed through the th insertion hole 854h is guided by the inclined surface so as to extend toward the outer peripheral side with respect to the support member 840 as shown in fig. 18.

Here, in the case where the belt extending direction regulating portion 859 is not provided in the support member 840, the belt portion 72 having passed through the th insertion hole 854h may extend along the outer surface of the extending portion 842c, and in this case, the wire harness 812 is hardly sandwiched between the support member 840 and the belt member 70 on the th insertion portion 854 side.

On the other hand, by providing the belt extending direction restricting portion 859 here, even on the th insertion portion 854 side, the wire harness 812 can be easily sandwiched between the support member 840 and the belt member 70.

In order to clamp the band member 70 to the th insertion part 854 and the second insertion part 856, for example, as shown in fig. 24, the distal end part 72a of the band member 72 is inserted into the th insertion part 854, at this time, the restriction part 74 may be held in advance by a jig or the like, the wire harness 812 is arranged along the outer periphery of the support member 840 in this state, the wire harness 812 may be arranged flat, for example, before being arranged, and it is conceivable to arrange the flat wire harness 812 along the outer periphery of the support member 840 by bending, and then, the band member 72 is wound outside the wire harness 812 and the distal end part 72a of the band member 72 is inserted and clamped to the second insertion part 856, and at this time, when the distal end part 72a of the band member 72 passing through the second insertion part 856 is pulled with a predetermined force as described above, the force passing through the band member 70 and the support member 840 can be set to a predetermined force.

According to this embodiment, since the support member 840 is provided with the th insertion portion 854 and the second insertion portion 856 as support portions, into which the belt member 70 can be inserted and which can be locked in a state in which the belt member 70 is inserted, the wire harness 812 can be supported by the support member 840 using the belt member 70.

Here, since the electric wire 14 is held in a tightly bound state between the belt member 70 and the support member 840 by the belt member 70, the electric wire 14 is supported at a fixed position with respect to the support member 840 and is hard to move, and particularly, the electric wire 14 is held so as not to move with respect to the fitting portion 842. therefore, it is possible to suppress the occurrence of vibration, friction, and the like in the electric wire 14. furthermore, it is easy to maintain a state in which the electric wire 14 is spread along the outer periphery of the rod-shaped member 460, and therefore, in a state in which the wire harness 810 with the support member is supported by the rod-shaped member 460, even in a region adjacent to the support member 840 in the longitudinal direction of the rod-shaped member 460, it is easy to maintain a state in which the electric wire 14 is spread along the outer periphery of the rod-shaped member 460, particularly, in the th region and the second region separated from each other in the longitudinal direction of the rod-shaped member 460, and even in a portion between the th region and the second region, through the belt member 70, respectively, and.

In particular, since the -th insertion portion 854 is formed so that the band portion 72 can be inserted and the regulating portion 74 cannot be inserted, and the second insertion portion 856 is formed so that the band portion 72 can be inserted in directions and cannot be inserted in the other directions, the harness 812 can be supported by the support member 840 using a common binding band as the band member 70.

In addition, according to this embodiment, since the wire 14 is sandwiched by the 2 sheets 30 and is formed flat as a whole, the wire 14 can be flat even without being fixed to the sheets 30.

In this case, the th insertion portion and the second insertion portion may be formed in the same shape as the second insertion portion 856 on which the belt locking portion 857 is formed.

(sixth embodiment)

Next, a description will be given of a wire harness with a support member and a support structure thereof according to a sixth embodiment, fig. 25 is a sectional view showing the wire harness with a support member 910 and a support structure thereof according to the sixth embodiment, fig. 26 is a plan view showing the support member 940 according to the sixth embodiment, fig. 27 is a perspective view showing a band member 970 used for the wire harness with a support member 910 according to the sixth embodiment, fig. 28 is an explanatory view showing a case where the wire harness with a support member 910 according to the sixth embodiment is manufactured, and in the description of the present embodiment, components similar to those described so far are denoted by symbols, and the description thereof is omitted.

Here, the mode in which the band member 970 is locked to the th insertion part 954 and the second insertion part 956 is different from the mode in which the band member 70 is locked to the th insertion part 854 and the second insertion part 856 in the wire harness 810 with a support member of the fifth embodiment.

Specifically, the belt member 970 includes a belt portion 972 and a plurality of projecting pieces 976 provided upright on main surfaces of the belt portion 972, the projecting pieces 976 are formed at an end and an end of the belt portion 972, respectively, and the projecting pieces 976 are formed in a plurality (5 in this case) in the longitudinal direction of the belt portion 972 at an end and an end of the belt portion 972 at intervals, whereby the fastening force of the belt member 970 can be adjusted on both end sides by selectively locking the projecting pieces 976 to the insertion portion 954 and the second insertion portion 956 at an end and an end 364 of the belt portion 972, for example, when the function of adjusting the fastening force is provided only at the end of the belt portion 972, the number of the projecting pieces 976 may be different from each other end and the end of the belt portion 972, for example, when the rubber pieces 976 are formed in a shape of the belt portion 972, the belt member 84 or more.

The height of the insertion holes 954h and 956h of the first and second insertion portions 954 and 956 is set to be equal to or larger than the thickness of the belt portion 972 and smaller than the sum of the thickness of the belt portion 972 and the height of the projection piece 976, whereby the portions of the belt portion 972 where the projection piece 976 is not formed can be inserted into the insertion holes 954h and 956h of the first and second insertion portions and 956, and the portions where the projection piece 976 is formed cannot be inserted into the insertion holes 954h and 956h of the first and second insertion portions 954 and 972.

In addition, in the insertion portion 954 and the second insertion portion 956, portions from the insertion holes 954h, 956h to the portion of the outer side surface are opened, and through the openings 954a, 956a, as shown in fig. 26, portions of the belt portion 972 where the projecting pieces 976 are not formed can be introduced into the insertion holes 954h, 956h, more specifically, the width dimensions of the openings 954a, 956a are set smaller than the width dimensions of the belt portion 972, and the belt portion 972 housed in the insertion holes 954h, 956h is less likely to come off from the openings 954a, 956a, and when the belt portion 972 is housed in the insertion holes 954h, 956h, the belt portion 972 can pass through the openings 954a, 956a by being bent with a line along the longitudinal direction as a fold as shown in fig. 26, or the like.

However, each of the projecting pieces 976 may be formed to be elastically deformable so as to be bent at a height direction intermediate portion or a coupling portion coupled to the belt portion 972, and the like so as to be able to reduce the height dimension. In this case, even if the portion of the belt portion 972 where the projection piece 976 is formed is bent and deformed so that the height dimension thereof decreases as described above, the portion can be inserted through the insertion holes 954h and 956h in the axial direction.

Here, the interval between the adjacent projecting pieces 976 at each end of the belt portion 972 may be set to be equal to or larger than the size of the insertion holes 954h and 956h in the axial direction.

In order to lock the belt member 970 to the first insertion portion 954 and the second insertion portion 956, it is preferable, for example, to lock a end of the belt member 970 to the 0 insertion portion 954 as shown in fig. 28, and in this case, the 1 insertion portion 954 may be positioned between the 2 projecting pieces 976, whereby it is possible to suppress the belt member 970 from falling off from the insertion portion 954 until the other end of the belt member 970 is locked to the second insertion portion 956, and in this state, the wire harness 812 is arranged along the outer periphery of the support member 940, and the locking ends and the other may be arranged in a state where the belt member 970 is wound outside the wire harness 812 and the other end of the belt member 970 is locked to the second insertion portion 956, and in this case where the belt member 972 is made of an elastic material such as rubber, when the belt member 972 is formed of the elastic material such as rubber, it is possible to determine which of the locking ends and other insert pieces 976 are located in the vicinity of the fastening state, and when the fastening force is required to be determined in advance, which of the locking pieces 976 and the locking pieces are located in the vicinity of the fastening state is extended elastic deformation.

(seventh embodiment)

Next, a wire harness with a support member and a support structure thereof according to a seventh embodiment will be described, fig. 29 is a sectional view showing the wire harness with a support member 1010 and the support structure thereof according to the seventh embodiment, and fig. 30 is a front view showing the support member 1040 according to the seventh embodiment, and in the description of the present embodiment, components similar to those described so far are denoted by , and the description thereof will be omitted.

Here, the shape of the positioning protrusion 1052 and the shape of the hole 1062 of the rod-like member 1060 corresponding thereto are different from the shape of the positioning protrusion 52 and the shape of the hole 62 of the rod-like member 460 corresponding thereto, which have been described so far.

Specifically, and 1052b are provided as the positioning protrusions 1052, and 1052b are provided in the support member 1040 instead of and 843, the fitting positioning protrusions 1052a and 1052b are provided with inner peripheral surfaces of portions of the 2 fitting portions 1042 located on the opposite side with respect to the rod-like member 1060, and the fitting positioning protrusions 1052a and 1052b are housed in holes 1062 formed in both side portions of the rod-like member 1060, whereby the fitting portion 1042 can be fitted to the rod-like member.

In this case, the surfaces (surfaces remaining after cutting) of the fitting positioning projections 1052a and 1052b on the side of the opening portion of the support member 1040 into which the rod member 1060 is introduced are tapered guide surfaces 1053 a. accordingly, when the rod member 1060 is introduced through the opening portion toward the inner peripheral side of the support member 1040, the guide surfaces 1053a of the fitting positioning projections 1052a and 1052b can first come into contact with the rod member 1060, and as a result, as shown in fig. 30, the support member 1040 is easily elastically deformed so as to enlarge the opening portion in the middle of the fitting positioning projections 1052a and 1052b being received in the hole 1062 of the rod member 1060.

The outer peripheral side surface 1053b of the fitting positioning projections 1052a and 1052b opposite to the guide surface 1053a extends in a direction orthogonal to the introduction direction of the rod member 1060. In a state where the fitting positioning projections 1052a and 1052b are accommodated in the hole 1062 of the rod-like member 1060, the outer peripheral side surface 1053b is engaged with the inner peripheral surface of the hole 1062, whereby the fitting portion 1042 is fitted to the rod-like member 1060.

Here, it is conceivable to form the fitting positioning protrusions 1052a and 1052b as holes 1062 into which the rod-like member 1060 can be press-fitted. Thus, in a state where the fitting positioning projections 1052a and 1052b are accommodated in the hole 1062 of the rod-like member 1060, backlash is less likely to occur between the support member 1040 and the rod-like member 1060. However, as a structure for preventing the support member 1040 and the rod-like member 1060 from being loosened in a state where the fitting positioning projections 1052a and 1052b are accommodated in the hole 1062 of the rod-like member 1060, a structure other than press fitting may be considered. For example, the inner peripheral surface of the support member 1040 may be formed slightly smaller than the outer peripheral surface of the rod-like member 1060, and the support member 1040 may be fitted to the rod-like member 1060 in a state where the support member 1040 is elastically deformed to slightly enlarge the opening portion.

According to this embodiment, since the fitting positioning projections 1052a and 1052b are provided as the positioning projections 1052, the fitting structure and the positioning structure are not provided separately. Further, since the fitting structure of the positioning protrusions 1052a and 1052b and the hole 1062 for fitting is set in the side portion of the rod-like member 1060, the worker can easily recognize the positioning protrusions 1052a and 1052b and the hole 1062 for fitting, and thus can easily perform the fitting operation, as compared with the case where the fitting structure of the positioning protrusion 52 and the hole 62 is provided in the upper portion of the rod-like member 460 (the central portion of the support member 440).

Further, since the outer peripheral side surface 1053b used for locking the positioning protrusions 1052a and 1052b for fitting is perpendicular to the introduction direction of the rod-shaped member 1060, even if a force is applied in a direction to separate the rod-shaped member 1060 from the support member 1040, the opening portion is less likely to be elastically deformed so as to expand, as compared with the case where the support member 840 is fitted to the rod-shaped member 460 using the fitting piece 843 whose locking surface is formed in a shape along the outer surface of the rod-shaped member 460, and thus the fitted state is less likely to be eliminated.

(eighth embodiment)

Next, a wire harness with a support member and a support structure thereof of an eighth embodiment will be described. Fig. 31 is a cross-sectional view showing a wire harness 1110 with a support member and a support structure thereof according to an eighth embodiment.

In the wire harness with a support member 1110 of the present embodiment, the sheet 30 is omitted from the wire harness 1112 in the case where the wire harness is supported by the support member using the band member as in the fifth to seventh embodiments. In the example shown in fig. 31, the wire harness with support member 1110 is a structure in which the sheet 30 is omitted in the wire harness with support member 810 of the fifth embodiment. In the case where the sheet 30 is omitted, as shown in fig. 31, the wires 14 are directly arranged on the outer periphery of the support member 840.

At this time, a portion of the electric wire 14 in the vicinity of the portion sandwiched by the band member 70 and the support member 840 may be connected to a connector, or may be held by the sheet 30, or may be formed into a bundle in a circular sectional shape as shown in fig. 16 and held in a fixed shape. This makes it easy to align the portions of the electric wires 14 sandwiched between the band member 70 and the support member 840 along the outer periphery of the fitting portion 842. Of course, the portion of the electric wire 14 near the portion sandwiched between the band member 70 and the support member 840 may not be held in a fixed shape.

For example, in the th to fourth embodiments, only the locking protrusion 44 is described as the support portion, but this is not essential, and as the support portion, there may be a case where only the recess 34, only the connector locking portion 48, or a combination of the recess 34 and the connector locking portion 48 is described, and furthermore, at 1 corner, the support portion may be configured by a plurality of the locking protrusion 44, the recess 34, and the connector locking portion 48, and furthermore, for example, in the harness 710 with a support member shown in fig. 17, 1 of the support members 740 may be set to any of the support members 840, 940, 1040 in the fifth to seventh embodiments, and for example, it is also possible to apply the positioning protrusions 1052a, 1052b for fitting to the support member of the embodiments, and for example, it is also possible to apply the positioning protrusions 1052a, 1052b for fitting to the end side of the support member (i.e., in the support member, the fitting pieces , a) for the end side of the positioning protrusion 1052 b.

Although the present invention has been described in detail as above, the above description is illustrative in all aspects and the present invention is not limited thereto. Numerous modifications, not illustrated, can be conceived without departing from the scope of the invention.
