[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0010] The wiring member of the present disclosure is as follows.

[0011] (1) A wiring member includes an electric wire including a bent portion arranged along a bending path, a bracket including a holding portion that holds the electric wire, and a vehicle fixing portion that protrudes outward from the holding portion, wherein the holding portion has a bend holding portion that holds the bent portion of the electric wire, and the bend holding portion has an inner wall portion located more inward than the electric wire along the bending path, and an outer wall portion located more outward than the electric wire. The bracket is a rigid member having rigidity sufficient to withstand fixing to a vehicle by the vehicle fixing portion. The electric wire is maintained in a bent shape by the inner wall portion and the outer wall portion provided on the bracket. This allows the wiring member to be more reliably maintained in a bent state even when the reaction force is large.

[0012] (2) The wiring member of (1) may further include a resin molded portion that is insert-molded with at least the bent portion and the bent retaining portion as insert target portions, and the vehicle fixing portion may be located outside the resin molded portion. This allows the electric wire to be fixed to the bracket by the resin molded portion, and prevents friction between the electric wire and the retaining portion. Also, the entire periphery of the electric wire can be protected by the resin molded portion. Furthermore, the bent retaining portion is prevented from being exposed, and the bent retaining portion is prevented from damaging surrounding components.

[0013] (3) In the wiring member of (2), the bending retaining portion may further have a connecting wall portion connecting the inner wall portion and the outer wall portion, and the resin of the resin molding portion may be interposed between the bending portion and the connecting wall portion, thereby suppressing friction between the bending portion and the connecting wall portion.

[0014] (4) In any one of the wiring members (1) to (3), the electric wire may be a multi-core electric wire having a plurality of electric core wires and a sheath covering the plurality of electric core wires, the bent portion being provided at the position of the sheath, and the plurality of electric core wires extending from an end of the sheath to be connected to a plurality of devices located in the undercarriage of a vehicle. The multi-core electric wire is an integrated electric core wire for a plurality of devices in the undercarriage, and the presence of the plurality of electric core wires at the sheath position increases the reaction force. Even in this case, the electric wire is maintained in a bent shape by the inner wall portion and the outer wall portion provided on the bracket.

[0015] (5) In the wiring member of any one of (1) to (4), the electric wire may further include a straight portion disposed along a straight path adjacent to the bent portion along the extension direction of the electric wire, the retaining portion may further have a straight retaining portion that retains the straight portion, and the vehicle fixing portion may be provided on the straight retaining portion. When the wiring member is attached to a vehicle, the wiring member vibrates with the vehicle fixing portion as a fixed point. Even in this case, by providing the vehicle fixing portion on the straight retaining portion, the bent portion is more likely to be maintained in a bent state by the bend retaining portion.

[0016] (6) In the wiring member of (5), the straight holding portion may have a first wall portion, a second wall portion, and a third wall portion, the first wall portion covering the electric wire from the same side as the inner wall portion or the outer wall portion, the second wall portion and the third wall portion protruding from both ends of the first wall portion and facing each other across the electric wire, and the vehicle fixing portion may extend from the second wall portion. This changes the orientation of the opening of the holding portion between the bent holding portion and the straight holding portion, making it possible to firmly hold the electric wire on all four sides during vibration, etc.

[0017] (7) In the wiring member of (6), the vehicle fixing portion may have a first extending portion extending from the second wall portion to face the first wall portion, and a distance between the first extending portion and the first wall portion may be larger than a distance between the inner wall portion and the outer wall portion. This allows the electric wire to be accommodated in the straightness holding portion through a gap between the first extending portion and the first wall portion.

[0018] (8) In the wiring member according to any one of (1) to (7), at least one of the inner wall portion and the outer wall portion may be provided continuously along the bending path, thereby achieving high rigidity in the bending retention portion.

[0019] (9) In the wiring member of any one of (1) to (8), at least one of the inner wall portion and the outer wall portion may be provided discontinuously along the bending path, thereby reducing the weight of the bracket.

[0020] (10) In the wiring member of any one of (1) to (9), one of the inner wall portion and the outer wall portion may be provided continuously along the bending path, and the other may be provided intermittently along the bending path. This allows the wall portion provided continuously along the bending path to increase the rigidity of the bending retention portion, while the wall portion provided intermittently along the bending path to reduce the weight of the bracket.

[0021] [Details of the embodiments of the present disclosure] Specific examples of wiring members according to the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0022] [Embodiment 1] The following describes the wiring member according to embodiment 1. Fig. 1 is a plan view showing a wiring member 10 according to embodiment 1. Fig. 2 is a perspective view showing a bracket 30.

[0023] The wiring member 10 includes an electric wire 20 and a bracket 30 .

[0024] The wiring member 10 may include a single electric wire or multiple electric wires. Here, an example will be described in which the wiring member 10 includes multiple electric wires. Here, an example will be described in which the wiring member 10 includes a multi-core electric wire 20 in which multiple electric wires are integrated. The multi-core electric wire 20 has multiple core electric wires 22 and a sheath 25. The sheath 25 covers the multiple core electric wires 22. The multiple core electric wires 22 are integrated by the sheath 25. The multiple core electric wires 22 are bundled together by the sheath 25 in the portion where the sheath 25 is provided. The multi-core electric wire 20 can be treated as a single electric wire at the position of the sheath 25. Hereinafter, the multi-core electric wire 20 may be simply referred to as an electric wire 20.

[0025] The core wire 22 is a coated wire. The core wire 22 includes a core wire 23 and a coating 24 that covers the core wire 23 (see FIG. 4). The core wire 23 is a conductive wire made of copper, a copper alloy, aluminum, an aluminum alloy, or the like. The core wire 23 may be a solid wire or a twisted wire. The coating 24 is an insulating coating made of resin or the like, and is formed by extrusion coating the resin around the core wire 23, for example. The coating 24 is made of polyethylene, for example.

[0026] The sheath 25 is an insulating coating made of resin or the like. The sheath 25 is formed by extrusion coating the resin around the plurality of core wires 22. The sheath 25 is made of, for example, polyurethane. The sheath 25 may be omitted.

[0027] It is assumed that the wiring member 10 will be disposed along a curved path in a vehicle or the like. For this reason, the multi-core electric wire 20 includes a bent portion 12 disposed along the bending path. Here, the bent portion 12 is provided at the position of the sheath 25. The electric wire 20 further includes a straight portion 14 disposed along a straight path adjacent to the bent portion 12 along the extension direction of the electric wire 20.

[0028] The shape into which the wiring member 10 is bent is determined by the positional relationship of the portion to which the end of the wiring member 10 is attached, the layout of any obstructions in the portion where the wiring member 10 is disposed, and the like.

[0029] The sheath 25 has an end portion that exposes the plurality of core electric wires 22 at a middle position in the direction in which the plurality of core electric wires 22 extend. As shown in Fig. 1 , the plurality of core electric wires 22 extend from the end portion of the sheath 25 and are connected to a plurality of devices 80 located in the undercarriage of a vehicle. The plurality of core electric wires 22 extending from the end portion of the sheath 25 usually branch into a plurality of wires and extend toward the devices 80 to be connected. Here, an example will be described in which the wiring member 10 includes four core electric wires 22. The four core electric wires 22 extending from the end portion of the sheath 25 branch into two wires: two core electric wires 22A and two core electric wires 22B.

[0030] The two core electric wires 22A are, for example, power supply lines that transmit electric power. For example, the core electric wires 22A may be power supply lines that supply electric power to an EPB (Electric Parking Brake) or an EMB (Electro-Mechanical Brake). In the example shown in Fig. 1, the tip ends of the core electric wires 22A are connected to a device 80 via a connector 28.

[0031] The two core electric wires 22B are, for example, signal wires that transmit signals. For example, the core electric wires 22B may be signal wires that transmit signals from a sensor that detects the wheel speed in an ABS (Anti-Lock Brake System). In the example shown in Fig. 1, the tip of the core electric wire 22B is integrated with the sensor (device 80).

[0032] The two core electric wires 22B may be covered with a sheath 26 at a midpoint in the extending direction to form a cable 27. The two core electric wires 22B may extend from the end of the sheath 25 as cable 27. The sheath 25 may appear to cover three wires: two core electric wires 22 and one cable 27.

[0033] The other end of the electric wire 20 may extend to the vehicle body side and may be connected to a device such as an electronic control unit arranged in the vehicle body.

[0034] The bracket 30 includes a holding portion 31 and a vehicle fixing portion 40. The bracket 30 is made of, for example, metal. The bracket 30 may also be made of hard resin. The bracket 30 is formed by bending and deforming a plate material such as a metal plate. The bracket 30 may also be a molded product formed by injection molding or the like.

[0035] The holding portion 31 holds the electric wire 20. The holding portion 31 has a bent holding portion 32. Here, the holding portion 31 further has a straight holding portion 36. The straight holding portion 36 is continuous with one end of the bent holding portion 32.

[0036] The bending holding portion 32 holds the bent portion 12 of the electric wire 20. The bending holding portion 32 has an inner wall portion 33 and an outer wall portion 34. The inner wall portion 33 is located more inward than the electric wire 20 in the bending path. The outer wall portion 34 is located more outward than the electric wire 20 in the bending path. The distance between the inner wall portion 33 and the outer wall portion 34 is the same as or larger than the diameter of the electric wire 20. Here, the distance between the inner wall portion 33 and the outer wall portion 34 is slightly larger than the diameter of the electric wire 20. At least one of the inner wall portion 33 and the outer wall portion 34 is provided continuously along the bending path. Here, both of the inner wall portion 33 and the outer wall portion 34 are provided continuously along the bending path.

[0037] The bending holding portion 32 further has a connecting wall portion 35. The connecting wall portion 35 connects the inner wall portion 33 and the outer wall portion 34. The connecting wall portion 35 is also provided continuously along the bending path. In the bending holding portion 32, the electric wire 20 is covered on three sides by the inner wall portion 33, the outer wall portion 34, and the connecting wall portion 35.

[0038] The straight holding portion 36 holds the straight portion 14 of the electric wire 20. The straight holding portion 36 has a first wall portion 37, a second wall portion 38, and a third wall portion 39. The first wall portion 37 covers the electric wire 20 from the same side as the inner wall portion 33 or the outer wall portion 34. Here, the first wall portion 37 covers the electric wire 20 from the same side as the inner wall portion 33. The second wall portion 38 and the third wall portion 39 protrude from both ends of the first wall portion 37. The second wall portion 38 and the third wall portion 39 face each other with the electric wire 20 therebetween. Either the second wall portion 38 or the third wall portion 39 covers the electric wire 20 from the same side as the connecting wall portion 35. Of the second wall portion 38 and the third wall portion 39, one wall portion from which the vehicle fixing portion 40 extends is the second wall portion 38, and the other wall portion is the third wall portion 39. Here, the second wall portion 38 covers the electric wire 20 from the same side as the connecting wall portion 35. The third wall portion 39 covers the electric wire 20 from the side opposite to the second wall portion 38 and the connecting wall portion 35. In the straightness holding portion 36, the electric wire 20 is covered from three sides by the first wall portion 37, the second wall portion 38, and the third wall portion 39.

[0039] The bent holding portion 32 and the straight holding portion 36 are continuous. Here, the connecting wall portion 35 and the second wall portion 38 are continuous. Here, the first wall portion 37 and the inner wall portion 33 are spaced apart in the extending direction of the electric wire 20. The first wall portion 37 is provided on a part of the second wall portion 38 along the extending direction of the electric wire 20. The first wall portion 37 may be continuous with the inner wall portion 33. The first wall portion 37 may be provided on the entire second wall portion 38 along the extending direction of the electric wire 20. The second wall portion 38 may be spaced apart from the connecting wall portion 35.

[0040] The opening of the bending holding portion 32 and the opening of the straight holding portion 36 are oriented in different directions. In each of the bending holding portion 32 and the straight holding portion 36, the electric wire 20 is covered on three sides by the wall portions. Two wall portions of the bending holding portion 32 and two wall portions of the straight holding portion 36 cover the electric wire 20 from the same side. The remaining wall portion of the bending holding portion 32 and the remaining wall portion of the straight holding portion 36 cover the electric wire 20 from different sides. Specifically, the inner wall portion 33 of the bending holding portion 32 and the first wall portion 37 of the straight holding portion 36 cover the electric wire 20 from the same side. The connecting wall portion 35 of the bending holding portion 32 and the second wall portion 38 of the straight holding portion 36 cover the electric wire 20 from the same side. The outer wall portion 34 of the bending holding portion 32 and the third wall portion 39 of the straight holding portion 36 cover the electric wire 20 from different sides. The bent holding portion 32 opens on the opposite side (the front side of the paper in FIG. 1) from the connecting wall portion 35. The straight holding portion 36 opens on the opposite side (the upper side of the paper in FIG. 1) from the first wall portion 37.

[0041] The vehicle fixing portion 40 protrudes outward from the retaining portion 31. The vehicle fixing portion 40 is provided on a portion of the retaining portion 31 along its extension direction. Here, the vehicle fixing portion 40 is provided on the straight retaining portion 36. The vehicle fixing portion 40 is not provided on the bent retaining portion 32. The vehicle fixing portion 40 extends from the second wall portion 38 of the straight retaining portion 36. The vehicle fixing portion 40 has a first extending portion 41 and a second extending portion 42. The first extending portion 41 extends from the second wall portion 38 to face the first wall portion 37. The second extending portion 42 extends from the first extending portion 41 to move away from the retaining portion 31. A screw hole 43 is formed in the second extending portion 42. The vehicle fixing portion 40 is fixed to the attachment location on the vehicle by a screw. The vehicle fixing portion 40 may also be fixed to the attachment location by other means such as welding or a fitting structure.

[0042] The distance between the first extending portion 41 and the first wall portion 37 is larger than the diameter of the electric wire 20. The distance between the first extending portion 41 and the first wall portion 37 is larger than the distance between the inner wall portion 33 and the outer wall portion 34. Since the second wall portion 38 is longer than the connecting wall portion 35 in the width direction of the electric wire 20, the distance between the first extending portion 41 and the first wall portion 37 is larger than the distance between the inner wall portion 33 and the outer wall portion 34.

[0043] The protruding dimension of the third wall portion 39 from the first wall portion 37 may be smaller than the protruding dimension of the second wall portion 38 from the first wall portion 37. The protruding dimension of the third wall portion 39 from the first wall portion 37 may be smaller than the protruding dimension of the connecting wall portion 35 from the inner wall portion 33. The protruding dimension of the first extending portion 41 from the second wall portion 38 may be smaller than the protruding dimension of the first wall portion 37 from the second wall portion 38. As a result, the opening in the straight holding portion 36 becomes wider, and the electric wire 20 can be easily accommodated in the straight holding portion 36 through the opening.

[0044] The bracket 30 may have through holes 44 formed therein for removing weight. In the example shown in Fig. 2, the through holes 44 are formed in the connecting wall portion 35 and the second wall portion 38. The through holes 44 in the connecting wall portion 35 are formed in the middle portion (here, the center portion) of the connecting wall portion 35 along the extension direction of the electric wire 20. The through holes 44 in the second wall portion 38 are formed in both end portions of the second wall portion 38 along the extension direction of the electric wire 20.

[0045] For example, the electric wire 20 is fixed to the bracket 30 in a state where it is held along the inner wall portion 33 of the bracket 30. Such a fixing manner is not particularly limited and can be set as appropriate. For example, as shown in Fig. 1, the electric wire 20 may be fixed to the bracket 30 by wrapping a binding member 60 such as an adhesive tape or a cable tie around the electric wire 20 and the bracket 30. Also, for example, the inner surface of the holding portion 31 and the outer surface of the electric wire 20 may be bonded with an adhesive or the like.

[0046] <Effects, etc.> According to the wiring member 10 configured as described above, the bracket 30 is a rigid member having enough rigidity to withstand being fixed to the vehicle by the vehicle fixing portion 40. The inner wall portion 33 and the outer wall portion 34 provided on the bracket 30 keep the wires 20 in a bent shape. This makes it possible to more reliably keep the wiring member 10 in a bent state even if the reaction force becomes large.

[0047] For example, consider a case where the initial state of the electric wire 20 is a straight state, and the electric wire 20 is held by the bending holding portion 32 in a state bent more than the initial state. In this case, the electric wire 20 tries to return to a direction in which the bending angle becomes gentler, and therefore, the reaction force of the electric wire 20 trying to return to the initial state acts on both ends of the outer wall portion 34, the middle portion of the inner wall portion 33, etc.

[0048] Also, for example, consider a case where the initial state of the electric wire 20 is a bent state and the electric wire 20 is held by the bending holding portion 32 in a state in which the bend is gentler than the initial state. In this case, the electric wire 20 tries to return to a direction in which the bend angle becomes sharper, and therefore, the reaction force of the electric wire 20 trying to return to the initial state acts on both ends of the inner wall portion 33, the middle portion of the outer wall portion 34, etc.

[0049] In either of the above two cases, the reaction force of the electric wire 20 attempting to return to its initial state can be received by the inner wall portion 33 and the outer wall portion 34. Therefore, even if the reaction force becomes large, the wiring member 10 can be more reliably maintained in the bent state.

[0050] Furthermore, since there is no large flange or the like on the inner peripheral side of the inner wall portion 33, a large space can be secured on the inner peripheral side of the inner wall portion 33. Therefore, even if the path of the wiring member 10 in the vehicle is such that peripheral members are located on the inner peripheral side of the inner wall portion 33, interference of the wiring member 10 with the peripheral members is suppressed.

[0051] Furthermore, the multi-core electric wire 20 is an integrated electric core wire 22 for a plurality of devices in the undercarriage, and the presence of a plurality of electric core wires 22 at the position of the sheath 25 increases the reaction force. Even in this case, the electric wire 20 is maintained in a bent shape by the inner wall portion 33 and the outer wall portion 34 provided on the bracket 30.

[0052] When the wiring member 10 is attached to a vehicle, the wiring member 10 vibrates with the vehicle fixing portion 40 as a fixed point. Even in this case, since the vehicle fixing portion 40 is provided on the straight holding portion 36, the bent portion 12 is likely to be held in a bent state by the bent holding portion 32.

[0053] Furthermore, the first wall 37 of the straight holding portion 36 covers the electric wire 20 from the same side as the inner wall 33 or the outer wall 34, and the second wall 38 and the third wall 39 protrude from both ends of the first wall 37 and face each other across the electric wire 20. This changes the orientation of the opening of the holding portion 31 between the bent holding portion 32 and the straight holding portion 36, making it possible to firmly hold the electric wire 20 on all four sides during vibration, etc.

[0054] The vehicle fixing portion 40 also has a first extending portion 41 extending from the third wall portion 39 so as to face the first wall portion 37, and the distance between the first extending portion 41 and the first wall portion 37 is greater than the distance between the inner wall portion 33 and the outer wall portion 34. This allows the electric wire 20 to be accommodated in the straight holding portion 36 through the gap between the first extending portion 41 and the first wall portion 37.

[0055] In addition, at least one of the inner wall portion 33 and the outer wall portion 34 is provided continuously along the bending path, thereby obtaining high rigidity in the bending holding portion 32. Here, both the inner wall portion 33 and the outer wall portion 34 are provided continuously along the bending path, thereby obtaining high rigidity in the bending holding portion 32.

[0056] [Embodiment 2] A wiring member according to a second embodiment will be described. Fig. 3 is a plan view showing a wiring member 110 according to the second embodiment. Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3. Fig. 5 is a cross-sectional view taken along line VV in Fig. 3. In the description of this embodiment, components similar to those described so far are designated by the same reference numerals, and description thereof will be omitted.

[0057] The wiring member 110 further includes a resin molded portion 50 in addition to the electric wire 20 and the bracket 30. The resin molded portion 50 is insert-molded with at least the bent portion 12 and the bent retaining portion 32 as insert target portions. The vehicle fixing portion 40 is located outside the resin molded portion 50. By including the resin molded portion 50 in the wiring member 110, the electric wire 20 can be fixed to the bracket 30 by the resin molded portion 50, and rubbing between the electric wire 20 and the retaining portion 31 is suppressed. Furthermore, the entire periphery of the electric wire 20 can be protected by the resin molded portion 50. Furthermore, exposure of the bent retaining portion 32 is suppressed, and damage to surrounding components by the bent retaining portion 32 is suppressed.

[0058] The resin molded part 50 includes a main body part 51. The main body part 51 covers the bracket 30 and the electric wires 20. The main body part 51 has a curved covering part 52 and a straight covering part 53. The resin molded part 50 further includes electric wire covering parts 54 and 55. The electric wire covering parts 54 and 55 cover only the electric wires 20 out of the bracket 30 and the electric wires 20.

[0059] The bending covering portion 52 extends in a bent state. The bending covering portion 52 covers the bending portion 12 and the bending holding portion 32. The bending covering portion 52 does not need to cover the entire bending portion 12 and the bending holding portion 32, but it is sufficient if it covers at least a part of the bending portion 12 and the bending holding portion 32.

[0060] The straight covering portion 53 extends linearly, continuing from the bent covering portion 52. The straight covering portion 53 covers the straight portion 14 and the straight holding portion 36. The straight covering portion 53 does not need to cover all of the straight portion 14 and the straight holding portion 36, but only needs to cover at least a portion of the straight holding portion 36. The vehicle fixing portion 40 is provided outside the straight covering portion 53. The tip of the second wall portion 38 protrudes laterally from the straight covering portion 53. The first extending portion 41 and the second extending portion 42 are exposed.

[0061] The wire covering portion 54 covers the wires 20 extending from one end of the bracket 30. The wire covering portion 55 covers the wires 20 extending from the other end of the bracket 30. The wire covering portion 54 is continuous with the bent covering portion 52, and the wire covering portion 55 is continuous with the straight covering portion 53. The wire covering portions 54 and 55 extend linearly.

[0062] The main body 51 is formed in a rectangular tube shape, and the wire covering parts 54, 55 are formed in a cylindrical shape. The main body 51 may be formed in a cylindrical shape or the like. The wire covering parts 54, 55 may be formed in a rectangular tube shape or the like.

[0063] In the wire covering portion 54, the thickness of the base end portion connected to the bent covering portion 52 is thicker than the thickness of the tip end portion from which the electric wire 20 extends. Because the base end portion of the wire covering portion 54 is connected to the end portion of the bent covering portion 52, it may receive a larger reaction force from the bent portion 12 than the tip end portion. In the wire covering portion 54, the base end portion is thicker than the tip end portion, so it is easier to withstand the reaction force from the bent portion 12. Here, in the wire covering portion 54, the thickness gradually increases from the tip end portion to the base end portion. The portion including the tip end portion may have a constant first thickness, and the portion including the base end portion may have a constant second thickness that is thicker than the first thickness.

[0064] The wire covering portion 55 has the same thickness at its base end portion connected to the straight covering portion 53 and its tip end portion from which the wire 20 extends. Because the base end portion of the wire covering portion 55 is connected to the end portion of the straight covering portion 53, there is unlikely to be a large difference in the reaction force received from the wire 20 between the base end portion and the tip end portion of the wire covering portion 55. Therefore, even if the wire covering portion 55 has a constant thickness, the wire 20 can be firmly held.

[0065] Since the reaction force of the electric wire 20 is mainly received by the bracket 30, the resin molded portion 50 is prevented from receiving a large reaction force of the electric wire 20. Therefore, the resin molded portion 50 has fewer thick portions that can receive a large reaction force of the electric wire 20. This reduces the weight and size of the wiring member 110 on which the resin molded portion 50 is provided.

[0066] The bracket 30 described above is a rigid member formed of metal, hard resin, or the like. Therefore, the bracket 30 has high rigidity and is suitable for maintaining the desired bending shape. However, there may be cases where the wiring member 10 is disposed in a narrow space where the holding portion 31 of the bracket 30 may come into contact with surrounding components. In this case, if the holding portion 31 of the bracket 30 is exposed, there is a risk of damaging the surrounding components that it comes into contact with.

[0067] The resin molded portion 50 as described above is formed of a resin such as polyurethane resin. Polyurethane resin has excellent impact resistance and is suitable for protecting the electric wire 20 and surrounding components that come into contact with the resin molded portion 50, but it is easily deformed. Therefore, when the bent portion 12 of the electric wire 20 is held by the resin molded portion 50, it may be difficult to hold the intended bent shape when the electric wire 20 inside tries to return to its original shape.

[0068] In such a case, the wiring member 110 including the bracket 30 and the resin molded portion 50 is more effective. That is, in the wiring member 110, the bracket 30 can hold the electric wire 20 in a desired bent shape, while the resin molded portion 50 can protect the electric wire 20 and surrounding components in contact with the electric wire 20.

[0069] The resin molded portion 50 as described above can be integrally formed by insert molding using an injection mold, for example, with the holding portion 31 and the portion of the electric wire 20 held by the holding portion 31 as an insert target portion. In other words, the resin molded portion 50 is a molded part.

[0070] As shown in FIG. 4 , the resin of the resin molded portion 50 may be interposed between the bent portion 12 and the connecting wall portion 35, so that the electric wire 20 does not come into contact with the connecting wall portion 35. This prevents the bent portion 12 and the connecting wall portion 35 from rubbing against each other. For example, when the resin molded portion 50 is molded, the electric wire 20 may be supported in a state where it is floating above the connecting wall portion 35. For example, a pin-shaped jig that supports the electric wire 20 may be passed through the through hole 44 of the bracket 30. A hole corresponding to the pin-shaped jig may be formed in the resin molded portion 50. However, the electric wire 20 may come into contact with the connecting wall portion 35.

[0071] [Note] FIG. 6 is a plan view showing a bracket 230 according to a first modified example.

[0072] In bracket 230 according to the first modified example, the shape of bending retaining portion 232 differs from the shape of bending retaining portion 32. In bending retaining portion 232, both inner wall portion 233 and outer wall portion 234 are provided discontinuously along the bending path. In this way, by providing at least one of inner wall portion 233 and outer wall portion 234 discontinuously along the bending path, bracket 30 is made lighter.

[0073] The inner wall portion 233 includes a plurality of small wall portions 33a. The plurality of small wall portions 33a are provided at intervals along the extending direction of the electric wire 20. A slit 33b is formed between the plurality of small wall portions 33a.

[0074] The outer wall portion 234 includes a plurality of small wall portions 34a. The plurality of small wall portions 34a are provided at intervals along the extension direction of the electric wire 20. A slit 34b is formed between the plurality of small wall portions 34a.

[0075] The number and size of the small wall portions 33a, 34a along the extension direction of the electric wire 20 can be set as appropriate. The number and size of the slits 33b, 34b along the extension direction of the electric wire 20 can be set as appropriate. For example, in the example shown in FIG. 6 , the slits 33b of the inner wall portion 233 and the slits 34b of the outer wall portion 234 are provided at the same position along the extension direction of the electric wire 20. The slits 33b of the inner wall portion 233 and the slits 34b of the outer wall portion 234 may be provided at different positions along the extension direction of the electric wire 20. The slits 33b of the inner wall portion 233 and the slits 34b of the outer wall portion 234 may have different width dimensions along the extension direction of the electric wire 20.

[0076] FIG. 7 is a plan view showing a bracket 330 according to the second modified example.

[0077] In bracket 330 according to the second modification, the shape of bending retaining portion 332 differs from the shapes of bending retaining portions 32, 232. In bending retaining portion 332, one of inner wall portion 233 and outer wall portion 34 is provided continuously along the bending path, and the other is provided intermittently along the bending path. As a result, the rigidity of bending retaining portion 32 is increased by the wall portion provided continuously along the bending path, while the weight of bracket 330 can be reduced by the wall portion provided intermittently along the bending path.

[0078] In the example shown in FIG. 7 , the outer wall portion 34 is provided continuously along the bending path, similar to the outer wall portion 34 of the bracket 30. Moreover, the inner wall portion 233 is provided intermittently along the bending path, similar to the inner wall portion 233 of the bracket 230. The inner wall portion 33 may be provided continuously along the bending path, and the outer wall portion 234 may be provided intermittently along the bending path. In the wall portion provided intermittently along the bending path, the number and size of each small wall portion 33a along the extension direction of the electric wire 20 can be set as appropriate. In the wall portion provided intermittently along the bending path, the number and size of each slit 33b along the extension direction of the electric wire 20 can be set as appropriate.

[0079] These brackets 230 and 330 can be applied to both Embodiments 1 and 2. That is, in the wiring member 10 of Embodiment 1, the brackets 230 and 330 may be applied instead of the bracket 30. In the wiring member 110 of Embodiment 2, the brackets 230 and 330 may be applied instead of the bracket 30.

[0080] Furthermore, although it has been described up to this point that the retaining portion 31 has the straight retaining portion 36 and the vehicle fixing portion 40 is provided on the straight retaining portion 36, this is not an essential configuration. Also, for example, the retaining portion 31 does not have to have the straight retaining portion 36. Also, for example, the vehicle fixing portion 40 may be provided on the bent retaining portion 32.

[0081] Furthermore, although the straight holding portion 36 has been described above as having the first wall portion 37, the second wall portion 38, and the third wall portion 39, this is not a required configuration. For example, the third wall portion 39 may be omitted from the straight holding portion 36, and the straight holding portion 36 may be configured with only the first wall portion 37 and the second wall portion 38. Furthermore, for example, the three sides on which the straight holding portion 36 covers the electric wire 20 may be the same as the three sides on which the bending holding portion 32 covers the electric wire 20. In place of the third wall portion 39, the straight holding portion 36 may be provided with a fourth wall portion that covers the electric wire 20 from the same side as the outer wall portion 34. In this case, the vehicle fixing portion 40 may extend from the first wall portion 37 or the fourth wall portion.

[0082] The wiring members 10, 110 may be used as composite harnesses including multiple types of electric wires 20. As described above, if the core electric wires 22A are power wires and the core electric wires 22B are signal wires, the wiring members 10, 110 are composite harnesses including a power wire (core electric wire 22A) and a signal wire (core electric wire 22B). In particular, if the wiring members 10, 110 include a power wire (core electric wire 22A) for an electric brake and a signal wire (core electric wire 22B) for vehicle speed detection, the wiring members 10, 110 are composite harnesses for a brake.

[0083] Furthermore, the wiring member 10, 110 may have six or more core electric wires 22. For example, two or three or more core electric wires 22 for ADS (Active Damper Suspension) may be added. The added core electric wires 22 may be power wires or signal wires. Power wires are often set to have a larger allowable current value than signal wires. For this reason, power wires are often thicker than signal wires. Therefore, if the added core electric wire 22 is a power wire, the reaction force of the electric wire 20 is larger than if the added core electric wire 22 is a signal wire. For this reason, if the added core electric wire 22 is a power wire, the bracket 30 can hold the bent portion 12 more effectively.

[0084] The configurations described in the above embodiments and modifications can be combined as appropriate as long as they are not mutually contradictory.
