[0019] [Description of Embodiments of the Present Disclosure]

[0020] First, embodiments of the present disclosure will be described below.

[0021] The wiring module for the walking part of the present disclosure is as follows.

[0022] (1) The running part wiring module includes a running part wiring member, the running part wiring member including a transmission line main body and at least one covering layer covering the transmission line main body. At least a portion of the running part wiring member is formed as an outdoor section disposed outdoors in the vehicle. In the outdoor section, an arcuate groove is formed on the outer skin of the outermost covering layer of the at least one covering layer. The arcuate groove formed on the outer skin of the running part wiring member facilitates bending of the running part wiring member.

[0023] (2) The running part wiring module of (1) may further include a plurality of fixing members, the plurality of fixing members being arranged at intervals along the extending direction of the running part wiring member to position the running part wiring member on the vehicle, wherein the arcuate groove is formed in a region between the plurality of fixing members. Thus, the portion of the running part wiring member between the fixing members is easily bent.

[0024] (3) In the running portion wiring module of (2), the plurality of fixing members may include a first fixing member and a second fixing member provided at a position downstream of the first fixing member, and the arcuate groove may be formed between the first fixing member and the second fixing member at a position closer to at least the first fixing member than a central position between the first fixing member and the second fixing member. Thus, the portion of the running portion wiring member near the first fixing member is easily bent.

[0025] (4) In the running portion wiring module of (3), a first arcuate groove and a second arcuate groove may be formed spaced apart from each other from the first fixing member in the extending direction of the running portion wiring member, and the distance between the first fixing member and the first arcuate groove may be larger than the distance between the first arcuate groove and the second arcuate groove. This can prevent the running portion wiring member from suddenly bending at a position close to the first fixing member.

[0026] (5) In any one of the running part wiring modules of (1) to (4), the thickness of the portion of the outer skin where the arcuate groove is formed may be thinner than the thickness of the other portion where the arcuate groove is not formed. Thus, the running part wiring member is locally thinned in the portion where the arcuate groove is formed, making it easier to bend.

[0027] (6) In any one of the running section wiring modules of (1) to (5), the arcuate groove may be formed in a section of the outdoor section that is repeatedly bent as the suspension swings. Thus, a structure that facilitates the bending of the running section wiring member is provided in a location where the wiring member is easily bent.

[0028] (7) In any one of the wiring modules for the running part of (1) to (6), the arcuate groove may be an annular groove. Thus, the wiring member for the running part can be easily bent at any position along the circumferential direction in the portion where the annular groove is formed.

[0029] [Details of the embodiments of the present disclosure]

[0030] The following is a reference to the attached Figure 1 While describing specific examples of the wiring module for the traveling portion of the present disclosure, the present disclosure is not limited to these examples, but is defined by the claims and includes all modifications within the meaning and scope of the equivalents to the claims.

[0031] [Implementation Method 1]

[0032] Hereinafter, the wiring module for the running part (hereinafter simply referred to as the wiring module) of the first embodiment will be described. The wiring module is a component provided for the running part of the vehicle. Figure 1 First, the structure of the traveling part of the vehicle will be described. Figure 1 It is a schematic diagram showing a configuration example of a traveling portion in a vehicle.

[0033] <Structural Example of the Running Part in a Vehicle>

[0034] The vehicle body 10 is a vehicle body in a car. Figure 1 , the figure shows the portion of the vehicle body 10 surrounding the wheel 18. The vehicle body 10 includes a floor portion 12 and a body portion 14. The floor portion 12 is the portion facing the ground. The body portion 14 is provided on the upper side of the floor portion 12 and constitutes the exterior of the vehicle body 10. The vehicle body 10 may be a monocoque in which a frame and a body, which are rigid bodies, are integrated, or it may be a structure in which a body is mounted on a frame. In the following description, the direction in which the vehicle normally travels may be referred to as the front, and the opposite direction may be referred to as the rear.

[0035] The wheels 18 are rotatably supported on the vehicle body 10. Figure 1 In the example shown, the wheel 18 is rotatably supported within the fender 16. The suspension device (Suspension: suspension) may be a device that supports the wheel 18 by any suspension method such as an axle suspension method, an independent suspension method, a torsion beam suspension method, etc. Figure 1 In the example shown, the lower arm 20 and the knuckle arm 24 support the wheel 18. More specifically, the lower arm 20 is arranged to extend in the front-to-rear direction of the vehicle body 10. Here, the base end of the lower arm 20 extends forward relative to the wheel 18. The base end of the lower arm 20 is supported by the vehicle body-side support portion 13 so that it can swing. The axis X, which serves as the center when the base end of the lower arm 20 swings, is the rotation axis X on the vehicle body 10 side when the lower arm 20 swings. In this embodiment, the rotation axis X extends along the left-right direction of the vehicle body 10. The base end of the lower arm can also be supported on the floor portion so that it can swing diagonally forward, inward, diagonally rearward, or rearward relative to the wheel. In these cases, the rotation axis on the vehicle body side when the lower arm swings can be along the left-right direction of the vehicle body, along the front-to-rear direction, or in a direction inclined relative to both the left-right and front-to-rear directions.

[0036] The top end of the lower arm 20 extends from the vehicle body side support portion 13 toward the inside of the fender 16 (here, toward the rear). A bearing 22 is provided at the top end of the lower arm 20. This bearing 22 rotatably supports the wheel 18 within the fender 16. The bearing 22 is also supported by a knuckle arm 24. The knuckle arm 24 is supported on the vehicle body 10 via a spring 26 and a shock absorber 28.

[0037] As described above, because the base end of the lower arm 20 is swingably supported by the vehicle body-side support portion 13, the lower arm 20 and the knuckle arm 24 support the wheel 18 so that it can move vertically within the fender 16. While the movement of the wheel 18 is restricted by the lower arm 20 and the knuckle arm 24, the spring 26 and the shock absorber 28 are interposed between the lower arm 20 and the knuckle arm 24 and the vehicle body 10. As the spring 26 and the shock absorber 28 absorb the impact of uneven road surfaces during driving, the wheel 18 swings vertically relative to the vehicle body 10.

[0038] A vehicle body-side device 80 is provided on the vehicle body 10 side, and a wheel-side device 90 is provided on the wheel 18 side. The vehicle body-side device 80 is incorporated into the vehicle body 10. The vehicle body-side device 80 does not move vertically with the wheel 18. The wheel-side device 90 is incorporated into the wheel 18. The wheel-side device 90 moves vertically relative to the vehicle body 10 with the wheel 18.

[0039] As wheel-side devices 90, sensors, electric brakes, and driving motors are assumed. Sensors, for example, detect the rotational speed of wheels 18. Electric brakes, which include an electric motor and other components, use electricity to brake the rotation of wheels 18. Electric brakes can be electric parking brakes used when the vehicle is parked or brakes used while the vehicle is moving. Driving motors are motors that are incorporated into wheels 18 to rotate them and are so-called in-wheel motors.

[0040] The vehicle-side device 80 is a device that transmits and receives signals to and from the wheel-side device 90 or supplies power. For example, the vehicle-side device 80 is an ECU (Electronic Control Unit) that receives signals from sensors and controls the electric brakes and the driving motor. In this embodiment, the vehicle-side device 80 is located within the vehicle body 10. However, the vehicle-side device 80 may also be located outside the vehicle body 10.

[0041] The wiring module 30 is a member that connects the vehicle body-side device 80 and the wheel-side device 90. The wiring module 30 is mounted on the vehicle in a state of being laid along a path connecting the vehicle body-side device 80 and the wheel-side device 90.

[0042] In this embodiment, a case is illustrated in which there is one vehicle-side device 80 and two wheel-side devices 90. The number of vehicle-side devices 80 and wheel-side devices 90 is not limited to this. There may be multiple vehicle-side devices 80. There may be one wheel-side device 90 or more. In addition, in this embodiment, a case is illustrated in which one end of the wiring module 30 is connected to the vehicle-side device 80. One end of the wiring module 30 may be connected to the vehicle-side device 80 via another wiring module. In addition, in this embodiment, a case is illustrated in which the other end of the wiring module 30 is connected to two wheel-side devices 90 at a single location. The other end of the wiring module 30 may branch and be connected to multiple wheel-side devices 90 at separate locations.

[0043] <Wiring Module>

[0044] Next, refer to Figures 2 to 4 The wiring module 30 will be described in detail. Figure 2 This is a schematic plan view showing the wiring module 30 according to the first embodiment. Figure 3 yes Figure 2 Magnified view of area A1. Figure 4 It is along Figure 3 Transverse cross-sectional view taken along line IV-IV. Figure 5 It is along Figure 4 A longitudinal cross-sectional view taken along line VV.

[0045] The wiring module 30 includes a running portion wiring member 40 (hereinafter simply referred to as the wiring member 40 ) and further includes a plurality of fixing members 60 , 62 , 64 , and 66 .

[0046] <Wiring Member>

[0047] The wiring member 40 connects the vehicle body device 80 and the wheel-side device 90. The wiring member 40 includes a transmission line body and at least one coating layer. The transmission line body transmits electricity or light. The transmission line body corresponds to a conductive body such as the core wire in an electric wire, or the core and coating in an optical fiber cable. The coating layer covers the transmission line body. Typically, the coating layer is a resin layer. The coating layer is formed by extruding a coating resin around the transmission line body. Here, an example is described in which the wiring member 40 includes four electric wires 41 and 44. The four electric wires 41 and 44 are composed of two electric wires 41 and two electric wires 44.

[0048] The wires 41 are, for example, power cables. The two wires 41 are the positive and negative wiring. For example, if the wiring member 40 is connected to an electric brake, the wires 41 can also be power cables for supplying power to drive the electric brake. For example, if the wiring member 40 is connected to a driving motor, the wires 41 can also be power cables for supplying power to drive the driving motor.

[0049] Wires 44 are, for example, signal lines. For example, if wiring member 40 is connected to a sensor, wires 44 may also be signal lines that output the sensor's detection signal. The two wires 44 may be a pair of wires 44 for transmitting differential signals. Alternatively, wires 44 may be signal lines that transmit control signals.

[0050] The structure of the wiring member 40 is not limited to the above-described structure. For example, the wiring member may include only power lines. In addition, for example, the wiring member may include only signal lines.

[0051] The wire 41 may be thicker than the wire 44. In this case, the conductor cross-sectional area of the wire 41 can be made larger than the conductor cross-sectional area of the wire 44, depending on the thickness of the wires 41 and 44. Therefore, as described above, it is suitable to use the wire 41 as a power line and the wire 44 as a signal line.

[0052] Wire 41 includes a core wire 42 and a sheath 43. Core wire 42 is formed from copper, a copper alloy, aluminum, or an aluminum alloy. Core wire 42 can be a collection of multiple wires (typically a twisted strand) or a single wire. Sheath 43 is formed by extruding a coating resin around core wire 42. Wire 44, like wire 41, includes a core wire 45 and a sheath 46. Each of the four wires 41 and 44 is a single-core, sheathed wire.

[0053] A sheath 47 as a coating is formed around the two electric wires 44 to form a cable 48. The sheath 47 is a resin that covers the two electric wires 44. The sheath 47 is formed by extruding a resin coating around the two electric wires 44.

[0054] A sheath 49 is formed around the two electric wires 41 and the cable 48 to form a cable 50. Thus, the wiring member 40 has a portion formed as the cable 50. The sheath 49 is a resin that covers the two electric wires 41 and the cable 48. The sheath 49 is formed by extruding a resin coating around the two electric wires 41 and the cable 48.

[0055] It is not essential that the two electric wires 44 be covered by the sheath 47. A coating layer may not be formed inside the sheath 49 and around the two electric wires 44. Alternatively, an external member such as a spirally wound tape, a corrugated tube, or a rubber tube may be provided inside the sheath 49 and around the two electric wires 44.

[0056] No sheath, exterior member, or the like is provided inside the sheath 49 and around the two electric wires 41. However, a sheath may be provided inside the sheath 49 and around the two electric wires 41. An exterior member such as a spirally wound tape, a corrugated tube, or a rubber tube may also be provided inside the sheath 49 and around the two electric wires 41.

[0057] The outermost coating layer of at least one coating layer in the wiring member 40 forms the outer sheath. The two wires 41 are provided with a coating 43 and a sheath 49 as the coating. The two wires 44 are provided with a coating 46 and sheaths 47 and 49 as the coating. For the four wires 41 and 44, the sheath 49 serves as the outer sheath. If the four wires 41 and 44 are not provided with sheaths 49, the coating 43 of the two wires 41 and the sheath 47 of the cable 48 serve as the outer sheath of the wiring member. Furthermore, if the four wires 41 and 44 are not provided with sheaths 47 and 49, the coatings 43 and 46 of the four wires 41 and 44 serve as the outer sheath of the wiring member.

[0058] Therefore, when the wiring component is a single-core wire such as an electric wire 41, the outer sheath is the outermost coating layer of the single-core wire. When the wiring component is a single-core wire such as the cable 50 described above, the outer sheath is the outermost coating layer (sheath) of the multi-core wire. In addition, the so-called multi-core wire here refers to a structure in which a single-core wire or a multi-core wire is a collection of either or both single-core wires and a multi-core wire, and the collection is concentrated by a single coating layer (sheath). A structure in which a single coating layer is extruded around multiple core wires is also a multi-core wire. When the wiring component is a wire harness, the coating layer of the wire located further outward in the wire harness is the outer sheath. In addition, the so-called wire harness refers to a structure in which a single-core wire or a multi-core wire is a collection of either or both single-core wires and a multi-core wire, and there is no sheath to concentrate the collection. For example, in the above example, when the sheath 49 is not present, the wiring component is formed into a wire harness. In addition, when the number of wires constituting the wire harness is large, wires located toward the center of the wire harness and not forming the peripheral shape of the wire harness can be produced. The covering layer of the wires that do not constitute the outer peripheral shape of the wire harness is not formed as the outer sheath.

[0059] An arcuate groove 52 is formed in the outer skin 49. The arcuate groove 52 will be described in detail later.

[0060] <Fixed parts>

[0061] The fixing components 60, 62, 64, and 66 are used to position the wiring member 40 in the vehicle. The fixing components 60, 62, 64, and 66 are arranged at intervals along the extending direction of the wiring member 40. The fixing components 60, 62, 64, and 66 include end connecting components 60, 62, a grommet 64, and a bracket 66.

[0062] The end connection components 60, 62 are components for connecting the ends of the wiring member 40 to the vehicle body side device 80 and the wheel side device 90, respectively. Here, the end connection components 60, 62 are connectors 60, 62. For example, the end connection components may be screw terminals or the like.

[0063] Connector 60 is provided at one end of wiring member 40. Connector 60 is a body-side connector that connects to vehicle-side equipment 80. Connector 62 is provided at the other end of wiring member 40. Connector 62 is a wheel-side connector that connects to wheel-side equipment 90. Connectors 60 and 62 have connector housings formed of resin or the like. For example, terminals are provided at the ends of wires 41 and 44. These terminals are inserted into cavities formed in the connector housings to form connectors 60 and 62. Connector 60 is connected to vehicle-side equipment 80, thereby connecting vehicle-side equipment 80 and wiring member 40. Connector 62 is connected to wheel-side equipment 90, thereby connecting wheel-side equipment 90 and wiring member 40. Connector 60 is connected to vehicle-side equipment 80, and connector 62 is connected to wheel-side equipment 90, thereby connecting vehicle-side equipment 80 and wheel-side equipment 90 via wiring member 40, enabling either or both power supply and communication.

[0064] The connector housings of connectors 60 and 62 are assumed to be molded separately from the wires 41 and 44. Alternatively, the connector housings of connectors 60 and 62 may be insert-molded bodies that are insert-molded with wiring member 40. In other words, the connector housings of connectors 60 and 62 may be molded by insert-molding the wires 41 and 44 and the terminals provided at the ends of the wires 41 and 44 as insert components.

[0065] At least one of the ends of the wiring member 40 and the other end may be directly connected to the vehicle-side device 80 or the wheel-side device 90 without the aid of the connectors 60 and 62. In this case, the wiring member is integrated with the vehicle-side device 80 or the wheel-side device 90. In this case, if a fixing member such as a bracket is provided on the vehicle-side device 80 or the wheel-side device 90, the fixing member serves to position and secure the wiring member. For example, the wheel-side device 90, such as a wheel speed sensor, may be integrated with the wiring member by insert molding.

[0066] Furthermore, the wires 41 and 44 are connected to the same connectors 60 and 62 at one and the other ends, respectively, but this is not a required configuration. The wires 41 and 44 may also be connected to different connectors at at least one of their one and the other ends. Furthermore, the wires 41 and 44 are connected to the same vehicle-side device 80 and wheel-side device 90 at one and the other ends, respectively, but this is not a required configuration. The wires 41 and 44 may also be connected to different devices at at least one of their one and the other ends.

[0067] A grommet 64 is provided at the middle of the length of the wiring member 40. The grommet 64 is an annular member formed of an elastic material such as rubber. The grommet 64 is fitted onto the wiring member 40. For example, an annular recess 65 is formed on the outer periphery of the grommet 64, into which the edge of the hole 17 fits. The grommet 64 is interposed between the wiring member 40 and the hole 17 or gap formed in the vehicle body 10. The grommet 64 protects the wiring member 40 and prevents water from entering the vehicle body 10.

[0068] Bracket 66 is provided in the middle of the length of wiring member 40. Bracket 66 is provided between grommet 64 and connector 62. Bracket 66 is formed by stamping a metal plate, for example. Bracket 66 includes a wiring assembly portion 67 and a vehicle assembly portion 68. Wiring assembly portion 67 is the portion that is assembled to wiring member 40. Here, wiring assembly portion 67 is assembled to wiring member 40 by undergoing plastic deformation (clamping) so as to surround wiring member 40. Vehicle assembly portion 68 is the portion that is assembled to the vehicle. Here, the vehicle assembly portion 68 is described as being assembled to a component in the vehicle that oscillates with wheel 18. An example of a component that oscillates with wheel 18 is the knuckle arm 24 that rotatably supports wheel 18. Vehicle assembly portion 68 has a threaded hole 69. For example, a bolt protrudes from knuckle arm 24. A nut is screwed into the bolt inserted through threaded hole 69. Thus, vehicle assembly portion 68 is assembled to knuckle arm 24. The bracket 66 may be attached to the wiring member 40 by a screw fastening structure or the like. The bracket 66 may be attached to the knuckle arm 24 by welding, an embedding structure or the like.

[0069] The fixing components 60, 62, 64, and 66 include vehicle body-side fixing components and wheel-side fixing components. The vehicle body-side fixing components are fixed to the vehicle body. They are fixed to a portion of the vehicle that does not swing vertically with the wheel 18. The wheel-side fixing components are fixed to the wheel 18. They are fixed to a portion that swings vertically with the wheel 18. Specifically, connector 60 and grommet 64 are vehicle body-side fixing components. Connector 62 and bracket 66 are wheel-side fixing components.

[0070] At least a portion of the wiring member 40 is formed as an outdoor section 40a. The outdoor section 40a is a section located outdoors within the vehicle. The wiring member 40 is routed outward through the hole 17 formed in the fender 16. The hole 17 can be formed in the fender 16 radially outward of the wheel 18 or inward in the vehicle width direction relative to the wheel 18. The section of the wiring member 40 from the portion outside the hole 17 to the other end connected to the wheel-side equipment 90 is the outdoor section 40a. In this embodiment, a grommet 64 is mounted in the hole 17. Therefore, the section of the wiring member 40 from the grommet 64 to the connector 62 connected to the wheel-side equipment 90 is the outdoor section 40a. However, the wiring member 40 can also be routed outward through a hole formed in the floor portion 12 of the vehicle body 10.

[0071] At least a portion of the outdoor section 40a is formed as a bending section 40b. The bending section 40b is a section that repeatedly bends as the suspension shakes. The bending section 40b is the section between the vehicle body-side fixing member and the wheel-side fixing member. The vehicle body-side fixing member is located on one side of the bending section 40b, while the wheel-side fixing member is located on the other side. Here, the bending section 40b is the section between the grommet 64 and the bracket 66.

[0072] The bending section 40b of the wiring member 40 is a portion that can bend and deform more significantly between the vehicle body 10 and the wheel 18 as a result of the wheel 18 shifting relative to the vehicle body 10. The bending section 40b is determined by factors such as the path and mounting position of the wiring member 40 in the vehicle. While a portion of the outdoor section 40a serves as the bending section 40b, the entire outdoor section 40a may also serve as the bending section 40b, or the entire wiring member 40 may serve as the bending section.

[0073] Figure 6 It is a schematic diagram explaining a state where the wiring module 30 is shaken. Figure 6 FIG. 4 shows the change in the bending mode of the bending section 40b when the wheel 18 is displaced up and down. Figure 6 In FIG. 1 , the wheel 18 indicated by the solid line is located above the wheel 18 indicated by the two-dot chain line by a height H.

[0074] Focusing on wiring member 40, hole 17 is located above connector 62. Therefore, the distance between hole 17 and connector 62 is susceptible to fluctuations due to vertical movement of wheel 18. In this case, the portion closer to connector 60 than grommet 64 is less susceptible to fluctuations in distance even when wheel 18 moves vertically, because both grommet 64 and connector 60 are fixed to the vehicle body. Similarly, the portion closer to connector 62 than bracket 66 is less susceptible to fluctuations in distance even when wheel 18 moves vertically, because both bracket 66 and connector 62 are fixed to the wheel. In contrast, the portion between grommet 64 and bracket 66 is more susceptible to fluctuations in distance corresponding to height H when wheel 18 moves vertically, because grommet 64 is fixed to the vehicle body and bracket 66 is fixed to the wheel.

[0075] In the state where the wheel 18 is located at the top ( Figure 6 In the state shown by the solid line in the figure, the distance between the guard ring 64 and the bracket 66 becomes smaller. Therefore, the bending section 40b is bent at a steep angle between the guard ring 64 and the bracket 66. In addition, in the state where the wheel 18 is located at the bottom (in the figure), the distance between the guard ring 64 and the bracket 66 becomes smaller. Figure 6 In the state shown by the two-dot chain line in the figure, the distance between the guard ring 64 and the bracket 66 increases. Therefore, the bending section 40b becomes straight or gently curved between the guard ring 64 and the bracket 66. Furthermore, the bending section 40b repeatedly bends as the wheel 18 repeatedly moves up and down.

[0076] <Arc groove>

[0077] The arcuate groove 52 is formed in the outer skin 49 of the wiring member 40 in the outdoor section 40a. Here, the portion of the wiring member 40 closer to the other end than the grommet 64 constitutes the outdoor section 40a. Furthermore, the outer skin 49 in this portion is the sheath 49. Therefore, the arcuate groove 52 is formed in the sheath 49 closer to the other end than the grommet 64. Furthermore, the arcuate groove 52 is not formed in the outer skin 49 of the wiring member 40 in the indoor section. Alternatively, the arcuate groove 52 may be formed in the outer skin 49 of the wiring member 40 in the indoor section.

[0078] The arcuate groove 52 is formed in the section between the plurality of fixing components 60, 62, 64, and 66. Here, the arcuate groove 52 is formed in the section between the bracket 66 and the connector 62. In addition, the arcuate groove 52 is formed in the section between the guard ring 64 and the bracket 66. The section between the guard ring 64 and the bracket 66 is also the bending section 40b. Therefore, the arcuate groove 52 is formed in the bending section 40b in the outdoor section 40a. The arcuate groove 52 does not need to be formed in both the section between the bracket 66 and the connector 62 and the section between the guard ring 64 and the bracket 66; it only needs to be formed in either section. When a plurality of wheel-side fixing components are provided, there are a plurality of sections between the plurality of fixing components in the outdoor section. In this case, it is sufficient that the arcuate groove is formed in at least one of the plurality of sections between the plurality of fixing components and in the outdoor section.

[0079] The arcuate groove 52 is formed between the first fixing member and the second fixing member, which is located at a position next to the first fixing member, at a position closer to at least the first fixing member than the center position between the first and second fixing members. The term "next position" may be used as viewed from either the vehicle body side end or the wheel side end.

[0080] Here, starting from the vehicle body side end, the connector 60, grommet 64, bracket 66, and connector 62 are arranged in this order. Starting from the wheel side end, the arrangement is in the reverse order. Therefore, here, the possible combinations of the first and second fixing members include a pair of the connector 60 and grommet 64, a pair of the grommet 64 and bracket 66, and a pair of the bracket 66 and connector 62. In each pair, one member serves as the first fixing member, and the other serves as the second fixing member.

[0081] Here, if Figure 2 As shown, in the set of the grommet 64 and the bracket 66, an arcuate groove 52 is formed at a position closer to the bracket 66 than the center position CP1 between the grommet 64 and the bracket 66. Furthermore, in the set of the bracket 66 and the connector 62, an arcuate groove 52 is formed at a position closer to the bracket 66 than the center position CP2 between the bracket 66 and the connector 62, and at a position closer to the connector 62. It is not necessary to provide all three of the arcuate groove 52 closer to the bracket 66 in the section between the grommet 64 and the bracket 66, and the arcuate groove 52 closer to the bracket 66 and the connector 62 in the section between the bracket 66 and the connector 62; any one or two of these may be omitted.

[0082] A first arcuate groove and a second arcuate groove are formed spaced apart from each other from the first fixing member in the direction in which the wiring member 40 extends. The distance between the first fixing member and the first arcuate groove is greater than the distance between the first arcuate groove and the second arcuate groove. In other words, the distance between the arcuate grooves 52 decreases as the distance from the first fixing member increases.

[0083] Here, if Figure 5 As shown, three arcuate grooves 52A, 52B, and 52C are formed between the guard ring 64 and the bracket 66 near the bracket 66. The three arcuate grooves 52A, 52B, and 52C are arranged in the order of arcuate groove 52A, arcuate groove 52B, and arcuate groove 52C starting from the bracket 66 side. Figure 5 The interval D1 shown is the interval between the bracket 66 and the arcuate groove 52A. Figure 5 The illustrated spacing D2 is the spacing between arcuate groove 52A and arcuate groove 52B, and the spacing D3 is the spacing between arcuate groove 52B and arcuate groove 52C. Spacing D1 is larger than spacing D2. Furthermore, spacing D2 is larger than spacing D3. Therefore, the spacing between arcuate grooves 52A, 52B, and 52C decreases as they move away from bracket 66. However, spacings D1, D2, and D3 may be the same. Alternatively, the spacing between arcuate grooves 52 may increase as they move away from bracket 66.

[0084] The thickness of the portion of the outer skin 49 where the arcuate groove 52 is formed is thinner than the thickness of the other portion where the arcuate groove 52 is not formed. Figure 4 The outer diameter D4 shown is the outer diameter of the portion of the outer skin 49 where the arcuate groove 52A is formed. Figure 4 The outer diameter D5 shown is the outer diameter of the other portion of the outer skin 49 where the arcuate grooves 52A, 52B, and 52C are not formed. The outer diameter D4 is smaller than the outer diameter D5. Therefore, the thickness of the portion of the outer skin 49 where the arcuate grooves 52A are formed is thinner than the thickness of the other portion where the arcuate grooves 52A, 52B, and 52C are not formed. The thickness of the portion where the arcuate grooves 52B and 52C are formed is also thinner than the thickness of the other portion where the arcuate grooves 52A, 52B, and 52C are not formed. However, the thickness of the portion of the outer skin 49 where the arcuate grooves 52A, 52B, and 52C are formed may be the same as or thicker than the thickness of the other portion where the arcuate grooves 52A, 52B, and 52C are not formed.

[0085] The arc groove 52 is an annular groove. Figure 4 As shown, the arcuate groove 52A is an annular groove formed over the entire circumference of the sheath 49. In the case where the wiring member is a wire harness, an arcuate groove is formed on the outer surface of all wires on the outer circumference, and when a plurality of arcuate grooves are combined to form an annular shape as a whole, it is considered an annular groove.

[0086] However, the arcuate groove 52 need not be an annular groove. For example, the arcuate groove 52 may be a semi-arc groove, or a groove with an angle greater than 0 degrees and less than 360 degrees. Furthermore, one end and the other end of the arcuate groove 52 may be located at the same position along the length of the wiring member 40. Alternatively, the arcuate groove 52 may be staggered along the length of the wiring member 40. Alternatively, the arcuate groove 52 may extend helically around the outer sheath 49.

[0087] The depth of arcuate groove 52A is greater than that of arcuate groove 52B. The depth of arcuate groove 52B is greater than that of arcuate groove 52C. In other words, the depths of arcuate grooves 52A, 52B, and 52C decrease as they move away from support 66. However, the depths of arcuate grooves 52A, 52B, and 52C may be the same. Alternatively, the depths of arcuate grooves 52A, 52B, and 52C may increase as they move away from support 66.

[0088] Arc grooves 52 similar to arc grooves 52A, 52B, and 52C are also formed between bracket 66 and connector 62 at positions near bracket 66. Arc grooves 52 similar to arc grooves 52A, 52B, and 52C are also formed between bracket 66 and connector 62 at positions near connector 62. However, arc grooves 52 formed at three locations, two locations near bracket 66 and one location near connectors 60 and 62, may be formed in a different manner.

[0089] The arcuate groove 52 can also be formed, for example, by providing an incision over the entire circumference of the sheath 49 by means of a blade. In this case, a portion of the sheath 49 may or may not be cut off. In addition, for example, the arcuate groove 52 can also be formed as follows. That is, two molds are prepared. Each mold has a pressing piece. The pressing piece is formed in a plate shape, and the inner circumference of one edge portion is formed in a semicircular arc shape. In the case where a plurality of arcuate grooves are formed in the wiring member, a plurality of pressing pieces are formed at intervals in each mold. Each pressing piece is formed to a size corresponding to the arcuate groove. In addition, when the sheath 49 is heated and softened, the wiring member 40 is clamped by the pressing pieces of the two molds. As a result, the resin in the portion of the sheath 49 where the pressing piece is placed retreats to its surroundings, and the arcuate groove 52 is formed in the portion where the pressing piece is placed. In this way, when the sheath 49 is melted to form the arcuate groove 52, as shown in FIG. Figure 5 As shown, a resin raised portion may be formed around the arc-shaped groove 52 .

[0090] <Effects of Embodiment 1, etc.>

[0091] According to the wiring module 30 configured as described above, the arcuate groove 52 formed in the outer skin 49 of the wiring member 40 facilitates bending of the wiring member 40. More specifically, the arcuate groove 52 formed in the outer skin 49 facilitates the concentration of stress on the arcuate groove 52 when the wiring member 40 is bent. As a result, the wiring member 40 is easily bent.

[0092] Furthermore, the arcuate groove 52 is formed in the section between the grommet 64 and the bracket 66. This facilitates bending in the section between the grommet 64 and the bracket 66 of the wiring member 40. The section between the grommet 64 and the bracket 66 is the bending section 40b. The arcuate groove 52 is formed in the bending section 40b of the outdoor section 40a. This facilitates bending of the wires 41 and 44 in a location where the wires 41 and 44 are prone to bending. Furthermore, the arcuate groove 52 is formed between the grommet 64 and the bracket 66 at a position closer to the bracket 66 than the center position CP1 between the grommet 64 and the bracket 66. This facilitates bending in the section of the wiring member 40 between the grommet 64 and the bracket 66 and near the bracket 66.

[0093] Furthermore, the distance D1 between the bracket 66 and the arcuate groove 52A is larger than the distance D2 between the arcuate groove 52A and the arcuate groove 52B. This prevents the wiring member 40 from being suddenly bent at a position close to the bracket 66.

[0094] Furthermore, the arcuate groove 52 is formed in the section between the bracket 66 and the connector 62. This makes the section between the bracket 66 and the connector 62 of the wiring member 40 easier to bend. The section between the bracket 66 and the connector 62 is closer to the wheel 18 and has a relatively densely packed component population. Therefore, the wiring member 40 is arranged to fill the gaps between the components. Therefore, since the section between the bracket 66 and the connector 62 is easier to bend, the wiring member 40 can be easily arranged near the wheel 18. Furthermore, the arcuate groove 52 is formed between the bracket 66 and the connector 62 at a position closer to the bracket 66 and at a position closer to the connector 62 than the center position CP2 between the bracket 66 and the connector 62. This makes the portion of the wiring member 40 between the bracket 66 and the connector 62 and near the bracket 66 easier to bend, as well as the portion near the connector 62.

[0095] The outer diameter D4 of the outer skin 49 portion where the arcuate groove 52 is formed is smaller than the outer diameter D5 of the other portion where the arcuate groove 52 is not formed. Therefore, the portion where the arcuate groove 52 is formed is locally narrowed by the wiring member 40, making it easier to bend.

[0096] Furthermore, the arcuate groove 52 is an annular groove. Therefore, the wiring member 40 can be easily bent at any position along the circumferential direction in the portion where the annular groove is formed.

[0097] [Modification]

[0098] A molded resin portion may be provided in the portion of wiring member 40 where bracket 66 is mounted. The molded resin portion is insert-molded with wiring member 40 as an insert component. The molded resin portion is provided, for example, to protect wiring member 40 during the tightening process of wiring mounting portion 67 in bracket 66. Alternatively, the wiring mounting portion in the bracket may be formed as an insert component together with wiring member 40 during molding of the molded resin portion. In this case, the molded resin portion serves as the component that mounts the bracket to wiring member 40.

[0099] When the electric wires 41 and 44 are branched in the middle, a molded resin portion may be provided at the branched portion. The bracket 66 may be attached to the molded resin portion provided at the branched portion.

[0100] The bracket 66 may be a vehicle body side fixing member. In this case, a bending section is formed between the bracket 66 and the connector 62.

[0101] Furthermore, the configurations described in the above-mentioned embodiments and modifications can be appropriately combined as long as they do not contradict each other.
