Description

Wire harness

[0001] The present disclosure relates to a wire harness.

[0002] Conventionally, there has been a wire harness that includes an electric wire member and a tubular exterior member that covers the outer periphery of the electric wire member and is provided along the extending direction of the electric wire member, and is fixed to the underside of a vehicle. The exterior member in such a wire harness has a bulging portion that bulges downward from a portion of its lower wall, and the bulging portion has a drainage hole (see, for example, Patent Document 1). In such a wire harness, even if water enters the interior of the exterior member, the water is drained through the drainage hole. Therefore, water is prevented from remaining inside the exterior member. Therefore, for example, when the electric wire member includes a braided wire, corrosion of the braided wire is suppressed.

[0003] JP 2016-96595 A

[0004] However, in the above-described wire harness, the shape of the exterior member having the bulge portion is complex. Furthermore, since the bulge portion is provided only in a part of the extending direction of the exterior member, it is necessary to fix the exterior member to the vehicle so that the bulge portion is positioned downward. In other words, it is necessary to set a slope in the exterior member so that water flows toward the bulge portion. Therefore, there is a risk that the mounting structure and mounting work of the exterior member will be complicated.

[0005] An object of the present disclosure is to provide a wire harness that has a simple configuration and is capable of suppressing water from remaining inside an exterior member.

[0006] The wire harness of the present disclosure is a wire harness including an electric wire member and an exterior member covering the outer periphery of the electric wire member and arranged along the extending direction of the electric wire member, wherein the exterior member includes an upper exterior member having an upper wall portion covering the upper side of the electric wire member and a pair of side wall portions covering the sides of the electric wire member, and a lower exterior member disposed between the pair of side wall portions and covering the lower side of the electric wire member, and the upper surface of the lower exterior member has an inclined surface that slopes downward toward the end in the width direction.

[0007] According to the wire harness of the present disclosure, it is possible to suppress water from remaining in the exterior member with a simple configuration.

[0008] Fig. 1 is a schematic diagram showing a wiring path of a wire harness in one embodiment. Fig. 2 is a partially exploded perspective view of an electric wire member and an exterior member in one embodiment. Fig. 3 is a cross-sectional view of the wire harness in one embodiment. Fig. 4 is a schematic side view of the wire harness in one embodiment. Fig. 5 is a cross-sectional view of a wire harness in another example.

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. A wire harness of the present disclosure is a wire harness including: [1] an electric wire member; and an exterior member covering an outer periphery of the electric wire member and provided along an extending direction of the electric wire member, wherein the exterior member includes an upper exterior member having an upper wall portion covering an upper side of the electric wire member and a pair of side wall portions covering lateral sides of the electric wire member, and a lower exterior member disposed between the pair of side wall portions and covering a lower side of the electric wire member, and an upper surface of the lower exterior member has an inclined surface that slopes downward toward an end portion in a width direction.

[0010] According to this configuration, the exterior member includes an upper exterior member having an upper wall portion and a pair of side walls, and a lower exterior member disposed between the pair of side walls. This allows for a gap to be provided between the widthwise end of the lower exterior member and the side walls. Furthermore, the upper surface of the lower exterior member has an inclined surface that slopes downward toward the widthwise end. Even if water seeps into the interior of the exterior member, the inclined surface directs the water toward the widthwise end of the lower exterior member. Therefore, the water is drained through the gap between the widthwise end of the lower exterior member and the side walls. This simple configuration prevents water from remaining trapped inside the exterior member, for example, without providing a slope to the exterior member.

[0011] [2] In the above [1], the inclined surface may be formed by a curved surface that is higher toward the center in the width direction of the lower exterior member. According to this configuration, since the inclined surface is formed by a curved surface that is higher toward the center in the width direction of the lower exterior member, for example, water can be effectively directed toward both ends in the width direction of the lower exterior member.

[0012] [3] In the above [1] or [2], the upper exterior member may have a pair of inner extensions that protrude from lower ends of the pair of side wall portions in a direction toward each other, below the lower exterior member, and the width of the lower exterior member may be set to be smaller than the distance between the pair of side wall portions and larger than the distance between the pair of inner extensions.

[0013] According to this configuration, the width of the lower exterior member is set to be smaller than the distance between the pair of side wall portions and larger than the distance between the pair of inner extension portions, thereby ensuring a gap between the widthwise end of the lower exterior member and the side wall portions and preventing the lower exterior member from falling off downward.

[0014] [4] In the above [3], at least one of the lower surface at the tip of the inner extension portion and the upper surface at the end in the width direction of the lower exterior member may have a separation force generating surface that generates a separation force so as to widen the gap between the pair of side wall portions when the lower exterior member is inserted into the upper exterior member.

[0015] According to this configuration, when the lower exterior member is inserted into the upper exterior member, a separating force is generated by the separating force generating surface so as to widen the gap between the pair of side wall portions, thereby improving assembly efficiency. In other words, when the lower exterior member is inserted into the upper exterior member, there is no need to apply an external force in a direction different from the insertion direction of the lower exterior member, which improves assembly efficiency.

[0016] [5] In any one of [1] to [4] above, a plurality of fixing members each having an attachment portion attached to a part of the extension direction of the exterior member and a fixing portion that can be fixed to the underside of a vehicle may be provided, and the attachment portion may have a support portion that supports the underside of the lower exterior member upward.

[0017] According to this configuration, the exterior member can be fixed to the underside of the vehicle at multiple locations in the extension direction by including multiple fixing members, each having an attachment portion attached to a portion of the exterior member in the extension direction and a fixing portion that can be fixed to the underside of the vehicle. The attachment portions have support portions that support the underside of the lower exterior member upward. Therefore, the portion of the lower exterior member supported by the support portions in the extension direction is positioned higher, and the lower exterior member curves downward as it moves away from the support portions. Therefore, even if water seeps into the interior of the exterior member, the water will flow downward due to the curvature of the lower exterior member along the extension direction. Therefore, the water will flow downward along the extension direction of the lower exterior member and be drained through the gap between the widthwise end of the lower exterior member and the side wall portion. This effectively prevents water from accumulating inside the exterior member.

[0018] [6] In any one of [1] to [5] above, each of the upper exterior member and the lower exterior member may be made of a resin material, and the cross-sectional shapes of the upper exterior member and the lower exterior member may be constant along their lengths.

[0019] According to this configuration, each of the upper exterior member and the lower exterior member is made of a resin material and has a uniform cross-sectional shape, so that they can be manufactured easily and inexpensively by extrusion molding, for example.

[0020] [7] In any one of [1] to [6] above, the electric wire member may include an electric wire and a tubular braided wire covering the outer periphery of the electric wire. According to this configuration, the electric wire member includes an electric wire and a tubular braided wire covering the outer periphery of the electric wire, and therefore the braided wire suppresses noise radiation from the electric wire. Furthermore, water is prevented from remaining inside the exterior member, which suppresses corrosion of the braided wire. Therefore, noise radiation from the electric wire can be stably suppressed.

[0021] [Details of the Embodiments of the Present Disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. In each drawing, for the convenience of explanation, some of the configurations may be exaggerated or simplified. Furthermore, the dimensional proportions of each part may differ from one drawing to another. Furthermore, the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0022] 1 electrically connects two or more electrical devices. The wire harness 10 of the present embodiment electrically connects an inverter 11 installed in the front of a vehicle V, such as a hybrid vehicle or an electric vehicle, to a high-voltage battery 12 installed behind the inverter 11 on the vehicle V.

[0023] The inverter 11 is connected to a wheel drive motor (not shown) that serves as a power source for running the vehicle. The inverter 11 generates AC power from DC power from a high-voltage battery 12 and supplies the AC power to the motor. The high-voltage battery 12 is a battery capable of supplying a voltage of, for example, several hundred volts.

[0024] The wire harness 10 is routed, for example, so as to pass under the floor of the vehicle V. Specifically, for example, the wire harness 10 is routed so as to extend from the inverter 11 to below an underfloor panel 13 of the vehicle V, further pass under the underfloor panel 13 to extend to the rear of the vehicle V, and further extend upward to the high-voltage battery 12. Note that the terms "upper" and "lower" used in describing the wire harness 10 in this embodiment refer to the upper and lower sides when the wire harness 10 is fixed to the vehicle V.

[0025] 2 and 3, the wire harness 10 includes an electric wire member 20 and an exterior member 30. Furthermore, as shown in FIGS. 3 and 4, the wire harness 10 includes a fixing member 40.

[0026] 2 and 3 , the electric wire member 20 has one or more electric wires 21 and a tubular braided wire 22 that covers the outer periphery of the electric wires 21. The electric wire member 20 of this embodiment has two electric wires 21. One end of the electric wire 21 is connected to the inverter 11, and the other end of the electric wire 21 is connected to the high-voltage battery 12. The electric wire 21 is, for example, a high-voltage wire that can handle high voltage and large current.

[0027] (Configuration of Electric Wire 21 ) Each electric wire 21 is a coated electric wire having a core wire 23 made of a conductor and an insulating coating 24 that coats the outer periphery of the core wire 23 .

[0028] The core wire 23 may be, for example, a twisted wire made by twisting together a plurality of conductive wires, or a single-core wire. The core wire 23 may be made of a metal material such as copper or aluminum. The cross section of the core wire 23 in this embodiment is formed to have a perfect circular shape.

[0029] The insulating coating 24 covers the entire outer periphery of the core wire 23. The insulating coating 24 is made of an insulating material such as a synthetic resin containing, as a main component, a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene.

[0030] (Configuration of the braided wire 22) The braided wire 22 is formed by weaving conductive wires. For example, a copper-based or aluminum-based metal material can be used as the material of the braided wire 22. The braided wire 22 of this embodiment covers two electric wires 21 together. In other words, the braided wire 22 of this embodiment is a multi-core lumped shield braided wire. Note that each figure shows a schematic diagram of the weaving of the wires of the braided wire 22. Furthermore, each end of the braided wire 22 is connected to an earth member (not shown) of a vehicle body, a metal case, or the like.

[0031] The wire member 20 including the two electric wires 21 and the braided wire 22 covering them collectively has a flat cross-sectional shape. Specifically, the cross-sectional shape of the wire member 20 of this embodiment is a flat shape in which the width direction (left-right direction in FIG. 3 ) along the direction in which the two electric wires 21 are aligned is the longitudinal direction, and the up-down direction (up-down direction in FIG. 3 ) along the direction in which the two electric wires 21 are not aligned is the lateral direction.

[0032] 2 and 3 , the exterior member 30 has an upper exterior member 31 and a lower exterior member 32. The upper exterior member 31 and the lower exterior member 32 are each made of a resin material such as polypropylene, polyamide, or polyacetal. Furthermore, the cross-sectional shape of each of the upper exterior member 31 and the lower exterior member 32 is constant throughout its length, and in this embodiment, they are extrusion-molded products.

[0033] 3 , the upper exterior member 31 has an upper wall portion 33 that covers the upper side of the wire member 20, and a pair of side wall portions 34 that extend downward from both sides of the upper wall portion 33 to cover the sides of the wire member 20. The upper exterior member 31 of this embodiment also has a pair of inner extension portions 35 that are lower than the lower exterior member 32 and protrude from the lower ends of the pair of side wall portions 34 in directions approaching each other.

[0034] (Configuration of Lower Exterior Member 32) The lower exterior member 32 is disposed between a pair of side wall portions 34 and configured to cover the lower side of the electric wire member 20, and is formed, for example, in a plate shape. The upper surface of the lower exterior member 32 has an inclined surface 36 that slopes downward toward the end in the width direction. In this embodiment, the inclined surface 36 is formed by a curved surface 37 that becomes higher toward the center in the width direction of the lower exterior member 32. In other words, the upper surface of the lower exterior member 32 is formed as the curved surface 37 that slopes higher toward the center in the width direction, and both sides of the curved surface 37 in the width direction are formed as inclined surfaces 36 that slope downward toward the end.

[0035] The width of the lower exterior member 32 is set to be smaller than the distance between the pair of side wall portions 34 and larger than the distance between the pair of inward extending portions 35. With this configuration, a gap S is formed between the end of the lower exterior member 32 in the width direction and the side wall portion 34.

[0036] Furthermore, the lower surface at the tip of the inner extension portion 35 of the upper exterior member 31 has a first separation force generating surface 38 that generates a separating force to widen the gap between the pair of side wall portions 34 when the lower exterior member 32 is inserted into the interior of the upper exterior member 31. The first separation force generating surface 38 in this embodiment is shaped to generate a separating force by forming the inner extension portion 35 in an arc shape.

[0037] Additionally, the upper surface of the widthwise end of the lower exterior member 32 has a second separation force generating surface 39 that generates a separating force so as to widen the gap between the pair of side wall portions 34 when the lower exterior member 32 is inserted into the upper exterior member 31. The second separation force generating surface 39 is formed as part of the inclined surface 36. Note that the widthwise end of the lower exterior member 32 in this embodiment is formed in an arc shape that protrudes downward.

[0038] With these configurations, when the lower exterior member 32 is moved upward relative to the upper exterior member 31 to insert the lower exterior member 32 into the upper exterior member 31, the first separating force generating surface 38 and the second separating force generating surface 39 widen the gap between the pair of side wall portions 34. When the lower exterior member 32 reaches above the inward extending portion 35, the pair of side wall portions 34 return to their shape before being widened, and the inward extending portion 35 prevents the lower exterior member 32 from falling off downward.

[0039] As shown in FIG. 3 , the downward length of the pair of side wall portions 34 is set so that, with the electric wire member 20 housed inside the exterior member 30, the end portion in the width direction of the lower exterior member 32 can be positioned above the inner extension portion 35 with a certain gap therebetween.

[0040] (Configuration of fixing member 40) As shown in Figures 3 and 4 , the fixing member 40 has an attachment portion 41 that is attached to a part of the exterior member 30 in the extending direction, and a fixing portion 42 that can be fixed to the underside of the vehicle V, specifically the underside of the underfloor panel 13 (see Figures 1 and 4 ). As shown in Figure 4 , the wire harness 10 includes a plurality of fixing members 40. Note that although Figure 4 illustrates two fixing members 40, the wire harness 10 may, of course, include three or more fixing members 40.

[0041] 3 , the mounting portion 41 has a support portion 43 that supports the lower surface of the lower exterior member 32 upward. More specifically, the mounting portion 41 of this embodiment has an upper portion 44 that covers the upper part of the upper wall portion 33, and a pair of side portions 45 that extend downward from both sides of the upper portion 44 to cover the sides of the pair of side wall portions 34. The mounting portion 41 also has a pair of lower portions 46 that extend toward each other from the lower ends of the pair of side portions 45, and a pair of support portions 43 that extend upward from the pair of lower portions 46 to support the lower surface of the lower exterior member 32 upward.

[0042] The fixing portion 42 is provided to protrude upward from the center of the upper portion 44. The fixing portion 42 is configured to be able to fit into, for example, a fixing hole (not shown) provided in the underfloor panel 13. The exterior member 30 is fixed to the underside of the underfloor panel 13 by a plurality of fixing members 40 attached at intervals in the extension direction of the exterior member 30, as shown in FIG.

[0043] With this configuration, as shown in Fig. 4, the portion of the lower exterior member 32 that is supported by the support portion 43 (see Fig. 3) is disposed at the upper end in the extension direction, and the lower exterior member 32 curves downward as it becomes farther away from the support portion 43. Note that Fig. 4 exaggerates the curved state of the lower exterior member 32 in an exaggerated schematic view.

[0044] (Operation of the embodiment) Next, an operation of the wire harness 10 configured as described above will be described. Since the exterior member 30 is formed by assembling the upper exterior member 31 and the lower exterior member 32, it can be attached to the wire member 20 afterward, for example. In other words, the upper exterior member 31 and the lower exterior member 32 can be attached to the wire member 20 from a direction perpendicular to the extending direction of the wire member 20. Furthermore, at the portion where the exterior member 30 is attached to the wire member 20, foreign objects such as flying stones are prevented from colliding with the wire member 20.

[0045] (Effects of the Embodiment) Next, the effects of the above embodiment are described below. (1) The exterior member 30 includes an upper exterior member 31 having an upper wall portion 33 and a pair of side wall portions 34, and a lower exterior member 32 disposed between the pair of side wall portions 34. This allows a gap S to be provided between the widthwise end of the lower exterior member 32 and the side wall portions 34. Furthermore, the upper surface of the lower exterior member 32 has an inclined surface 36 that slopes downward toward the widthwise end. Therefore, even if water seeps into the interior of the exterior member 30, the water will flow along the inclined surface 36 toward the widthwise end of the lower exterior member 32. Therefore, the water will be drained through the gap S between the widthwise end of the lower exterior member 32 and the side wall portions 34. Therefore, for example, it is possible to prevent water from remaining inside the exterior member 30 with a simple configuration without providing a slope to the exterior member 30.

[0046] (2) The inclined surface 36 is formed by a curved surface 37 that becomes higher toward the center of the width of the lower outer member 32. Therefore, for example, water can be effectively directed toward both ends of the width of the lower outer member 32.

[0047] (3) The upper exterior member 31 has a pair of inward extending portions 35 that protrude toward each other from the lower ends of the pair of side wall portions 34 below the lower exterior member 32. The width of the lower exterior member 32 is set to be smaller than the distance between the pair of side wall portions 34 and larger than the distance between the pair of inward extending portions 35. Therefore, a gap S can be secured between the widthwise ends of the lower exterior member 32 and the side wall portions 34, and the inward extending portions 35 can prevent the lower exterior member 32 from falling off downward.

[0048] (4) The lower surface at the tip of the inward extending portion 35 of the upper exterior member 31 has a first separating force generating surface 38 that generates a separating force to widen the gap between the pair of side wall portions 34 when the lower exterior member 32 is inserted into the upper exterior member 31. Furthermore, the upper surface at the widthwise end of the lower exterior member 32 has a second separating force generating surface 39 that generates a separating force to widen the gap between the pair of side wall portions 34 when the lower exterior member 32 is inserted into the upper exterior member 31. Therefore, when the lower exterior member 32 is inserted into the upper exterior member 31, a separating force is generated by the first separating force generating surface 38 and the second separating force generating surface 39 to widen the gap between the pair of side wall portions 34, improving assembly ease. In other words, when the lower exterior member 32 is inserted into the upper exterior member 31, there is no need to apply an external force in a direction different from the insertion direction of the lower exterior member 32, improving assembly ease.

[0049] (5) The exterior member 30 includes multiple fixing members 40, each having an attachment portion 41 attached to a portion of the exterior member 30 in the extension direction and a fixing portion 42 that can be fixed to the underside of the vehicle V. This allows the exterior member 30 to be fixed to the underside of the vehicle V at multiple locations in the extension direction. Furthermore, the attachment portions 41 have support portions 43 that support the underside of the lower exterior member 32 upward. Therefore, the portion of the lower exterior member 32 supported by the support portions 43 in the extension direction is positioned higher, and the lower exterior member 32 curves downward as it moves away from the support portions 43. Therefore, even if water seeps into the interior of the exterior member 30, the water will flow downward due to the curvature of the lower exterior member 32 along the extension direction. Therefore, the water will flow downward along the extension direction of the lower exterior member 32 and be drained through the gap S between the widthwise end of the lower exterior member 32 and the side wall portion 34. This further prevents water from remaining inside the exterior member 30.

[0050] Furthermore, in a configuration such as this embodiment in which the upper exterior member 31 has a pair of inner extending portions 35 and the width of the lower exterior member 32 is set larger than the distance between the pair of inner extending portions 35, a drainage flow path can be secured. That is, in a configuration in which the upper exterior member 31 has a pair of inner extending portions 35 and the width of the lower exterior member 32 is set larger than the distance between the pair of inner extending portions 35, there is a risk that the drainage flow path will be blocked when the lower exterior member 32 rests on the pair of inner extending portions 35. In contrast, the support portions 43 can lift the lower exterior member 32 above the pair of inner extending portions 35, thereby securing a drainage flow path.

[0051] (6) Each of the upper outer member 31 and the lower outer member 32 is made of a resin material, and the cross-sectional shapes of the upper outer member 31 and the lower outer member 32 are constant throughout their length. Therefore, the upper outer member 31 and the lower outer member 32 can be easily and inexpensively manufactured by, for example, extrusion molding.

[0052] (7) Since the electric wire member 20 includes the electric wire 21 and the tubular braided wire 22 that covers the outer periphery of the electric wire 21, the braided wire 22 suppresses noise radiation from the electric wire 21. Furthermore, water is prevented from remaining inside the exterior member 30, which suppresses corrosion of the braided wire 22. Therefore, noise radiation from the electric wire 21 can be stably suppressed.

[0053] (Modifications) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0054] In the above embodiment, the inclined surface 36 of the lower exterior member 32 is formed by a curved surface 37 that becomes higher toward the center in the width direction of the lower exterior member 32, but this is not limited to this, and the inclined surface may be changed to another inclined surface that slopes downward toward the end in the width direction.

[0055] For example, it may be modified as shown in Fig. 5. In this example, the upper surface of the lower exterior member 51 has a flat surface 52 in the center in the width direction, and inclined surfaces 53 on both sides of the flat surface 52 that slope downward toward the ends in the width direction.

[0056] In the above embodiment, the upper exterior member 31 has the inward extending portion 35, but this is not limited thereto and may be modified to a configuration that does not include the inward extending portion 35. For example, the upper exterior member 61 may be modified as shown in Fig. 5. In this example, the upper exterior member 61 has an upper wall portion 62 that covers the upper side of the wire member 20 and a pair of side wall portions 63 that extend downward from both sides of the upper wall portion 62 to cover the sides of the wire member 20, and does not include the inward extending portion 35 of the above embodiment.

[0057] In the above embodiment, the lower surface at the tip end of the inward extending portion 35 of the upper exterior member 31 has the first separation force generating surface 38, and the upper surface at the end in the width direction of the lower exterior member 32 has the second separation force generating surface 39. However, this is not limited to this. For example, a configuration may be adopted in which either the first separation force generating surface 38 or the second separation force generating surface 39 is not provided. Furthermore, for example, a configuration may be adopted in which neither the first separation force generating surface 38 nor the second separation force generating surface 39 is provided.

[0058] In the above embodiment, the mounting portion 41 of the fixing member 40 has a support portion 43 that supports the lower surface of the lower exterior member 32 upward, but this is not limited to this, and for example, the fixing member 40 may be configured not to have a support portion 43.

[0059] In the above embodiment, each of the upper exterior member 31 and the lower exterior member 32 is an extrusion molded product made of a resin material and having a constant cross-sectional shape, but this is not limited to this. For example, the cross-sectional shape of the upper exterior member 31 and / or the lower exterior member 32 may be different in part of the extension direction.

[0060] In the above embodiment, the electric wire member 20 has an electric wire 21 and a tubular braided wire 22 that covers the outer periphery of the electric wire 21, but this is not limited to this, and for example, the electric wire member 20 may have a configuration that does not have the braided wire 22.

[0061] In the above embodiment, the electric wire member 20 has two electric wires 21, but is not limited thereto and may have, for example, three or more electric wires 21. Furthermore, in the above embodiment, the core wire 23 of the electric wire 21 has a cross-sectional shape formed in a perfect circle, but is not limited thereto and may have, for example, a cross-sectional shape formed in a square.

[0062] In the above embodiment, the fixing portion 42 of the fixing member 40 is provided to protrude upward from the center of the upper portion 44 and is configured to be able to fit into a fixing hole not shown, but the fixing portion may be changed to one with a different configuration as long as it can be fixed to the underside of the vehicle V.

[0063] As in the illustrated non-limiting embodiment, the upper surface of the lower exterior member 32 may be configured to encourage liquids, such as water droplets, to move outward in the width direction of the lower exterior member 32 and to drip down from the lower exterior member 32, and may be a convex curved surface, for example, as shown in Figures 2 and 3. The lower surface of the lower exterior member 32 may be, but is not limited to, a flat surface.

[0064] As in the illustrated non-limiting embodiment, the wire harness 10 may include one or more fixing members 40 for fixing the exterior member 30 in a suspended state relative to the underside of the vehicle V. Each fixing member 40 may include a fixing portion 42 configured to be fixed to the underside of the vehicle V, an attachment portion 41 attached so as to surround a certain length position of the exterior member 30, and a support portion 43 that supports the lower surface of the lower exterior member 32 from below. As in the example shown in FIGS. 3 and 5 , when the attachment portion 41 of the fixing member 40 is attached so as to surround a certain length position of the exterior member 30, the attachment portion 41 may restrict movement of the upper exterior member 31 in the height direction relative to the attachment portion 41, and the support portion 43 may lift the lower exterior member 32 upward along the side wall portion 34 of the upper exterior member 31. Cooperation between the attachment portion 41 and the support portion 43 may form, enlarge, and / or maintain a gap S for liquid drainage between the lower exterior member 32 and the upper exterior member 31 at the longitudinal position of the exterior member 30 to which the fixing member 40 is attached. Cooperation between the attachment portion 41 and the support portion 43 may press or clamp the wire member 20 in the height direction (e.g., in the thickness direction of the wire member 20) between the upper exterior member 31 and the lower exterior member 32. The fixing member 40 may hold the upper exterior member 31, the wire member 20, and the lower exterior member 32 inside the attachment portion 41 so that they cannot move at least in the height direction.

[0065] In the illustrated non-limiting embodiment, the braided wire 22 of the wire member 20 may be the outermost surface of the wire member 20 .
