Abstract
Description
[Technical Field]
[0001] The present invention relates to a wire harness and a power supply device. [Background technology]
[0002] Conventionally, vehicles equipped with sliding doors are provided with a wire harness connecting the vehicle body and the sliding door. This wire harness is formed to bend in accordance with the opening and closing of the sliding door, and a wire harness equipped with a restricting member that restricts bending in a predetermined direction to a predetermined amount to prevent interference with the vehicle body or the like when bending is known (see, for example, Patent Document 1). The wire harness described in Patent Document 1 includes electric wires, a flexible corrugated tube through which the electric wires are inserted, and a bending restricting member (restricting member) disposed along the electric wires between the outer surface of the electric wires and the inner surface of the corrugated tube. For example, on an XY plane intersecting the up-down direction, the bending restricting member allows the wire harness extending in the front-rear direction to bend in an allowable direction toward the door and restricts bending in a restricted direction toward the vehicle body.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-192259 Summary of the Invention [Problem to be solved by the invention]
[0004] However, the above-described configuration of restricting the bending direction of a wire harness using a restricting member may have the following problems. For example, a wire harness may be left unattached to the corrugated tube. Furthermore, the restricting direction regulated by the restricting member varies depending on the type of wire harness. Therefore, when a completed wire harness is assembled to a vehicle body or the like, a wire harness that does not allow bending in the intended direction may be incorrectly assembled. If an assembly error or an incorrect assembly error is overlooked and later discovered, the assembly of structures related to the wire harness may need to be extensively redone, resulting in increased labor. To address these problems, a conceivable approach would be to actually bend the corrugated tube or the like before attaching the wire harness to the vehicle body and check its operation to avoid forgetting or incorrect assembly. However, checking its operation every time before assembly is cumbersome and makes it difficult to manufacture the wire harness.
[0005] An object of the present invention is to provide a wire harness and a power supply device in which the restricted bending direction can be easily confirmed. [Means for solving the problem]
[0006] In order to solve the problem and achieve the object, a wire harness includes an electric wire, a corrugated tube circumferentially covering the electric wire, a regulating member that regulates bending of the electric wire and the corrugated tube in a predetermined direction, and a holding member that holds the regulating member, wherein the regulating member includes a regulating portion that is arranged along the longitudinal direction of the electric wire within the corrugated tube and regulates the electric wire and the corrugated tube from bending more than a predetermined amount in a direction that intersects with the axial direction of the electric wire, and a held portion that protrudes outward from an end of the corrugated tube and is housed in the holding member, wherein the held portion is provided with a sign portion that allows the predetermined direction to be recognized, and the holding member is provided with a window portion that allows the sign portion to be visible from the outside. [Effects of the Invention]
[0007] According to the present invention, it is possible to provide a wire harness and a power supply device in which the restricted bending direction can be easily confirmed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0009] The wire harness 1 will be described below. For example, in a vehicle with a sliding door, the wire harness 1 constitutes a power supply device 100 together with a power source on the vehicle body side and an electrical device on the sliding door side, and connects the power source and the electrical device. In the drawings, the symbols X, Y, and Z indicate directions and are perpendicular to one another. The direction indicated by the symbol X is the axial direction of an electric wire 10 (described later) and is referred to as the "axial direction X." One side of the axial direction X is referred to as the "vehicle body side X1," and the other side is referred to as the "door side X2." The direction indicated by the symbol Y is the width direction (crossing direction) and is referred to as the "width direction Y." One side of the width direction Y is referred to as the "left side Y1," and the other side is referred to as the "right side Y2." The direction indicated by the symbol Z is the vertical direction in the vehicle and is referred to as the "vertical direction Z." One side of the vertical direction Z is referred to as the "upper side Z1," and the other side is referred to as the "lower side Z2." It should be noted that these definitions of directions are given only for the convenience of explanation and do not limit the directions when the wire harness 1 is manufactured or used.
[0010] As shown in FIG. 1, the wire harness 1 includes an electric wire 10, a corrugated tube 20, a corrugated guide 30 (a restricting member), and a rotor 40 (a holding member). In this embodiment, the rotor 40 is illustrated as being disposed at an end of the electric wire 10 on the vehicle body side X1, as shown in FIG. 1. The rotor disposed at an end of the electric wire 10 on the door side X2 has the same structure as the rotor 40, and therefore will not be illustrated or described in detail. The electric wire 10 is, for example, a covered electric wire including a core wire (not shown) and a covering circumferentially covering the core wire. A plurality of the electric wires 10 are bundled together and extend in the axial direction X, and are bendable in the width direction Y. The corrugated tube 20 is a tubular member that circumferentially covers the electric wires 10 inserted in the axial direction X, and is formed using a flexible resin material or the like. The corrugated tube 20 has large diameter portions 21 and small diameter portions 22 arranged alternately in the axial direction X, and is bellows-shaped and can be bent in the width direction Y.
[0011] A corrugated guide 30 is provided inside the corrugated tube 20 to restrict the wire 10 and the corrugated tube 20 from bending more than a predetermined amount in the width direction Y. The corrugated guide 30 is formed using a resin material and includes a held portion 31 and a restricting portion 36, as shown in FIG. 2. The held portion 31 is a portion that protrudes from the end of the corrugated tube 20 on the vehicle body side X1 toward the vehicle body side X1 (outward) and is accommodated in the rotor 40. The held portion 31 includes a main body 32 extending in the axial direction X. The main body 32 is formed in a generally C-shape and includes a generally rectangular upper wall 32a, a side wall 32b extending from an edge of the upper wall 32a on the right side Y2 to the lower side Z2, and a lower wall (not shown) facing the upper wall 32a on the lower side Z2 of the upper wall 32a. The main body 32 covers the upper side Z1, the right side Y2, and the lower side Z2 of the wire 10.
[0012] An upper surface of the upper wall 32a forms an opposing surface 33 opposing a window portion 67 of the rotor 40, which will be described later, in the up-down direction Z. A flange portion 34 is formed at an end portion of the main body portion 32 on the vehicle body side X1, protruding outward in an intersecting direction intersecting the axial direction X. A protrusion portion 35 protruding toward the vehicle body side X1 is formed at a part of the end surface of the flange portion 34 on the vehicle body side X1. The protrusion portion 35 is a portion that faces a restricting rib 65 (see FIG. 6) of the second rotor cover 60 in the axial direction X when the corrugated guide 30 is attached to the rotor 40, and is formed in the shape of a substantially rectangular protrusion.
[0013] Next, the restricting portion 36 will be described. The restricting portion 36 is a portion that restricts the electric wire 10 and the corrugated tube 20 from bending more than a predetermined amount in the width direction Y, and is molded integrally with the main body portion 32 and disposed inside the corrugated tube 20. The restricting portion 36 includes a plurality of member pieces 37 that are disposed at predetermined intervals along the longitudinal direction of the electric wire 10, and a connecting portion 38 that connects adjacent member pieces 37 to each other and extends in the longitudinal direction of the electric wire 10. Note that although two member pieces 37 are illustrated in FIG. 2, in reality, two or more member pieces 37 are provided between the vehicle body side X1 and the door side X2.
[0014] The member piece 37 is formed in a substantially C-shape and includes a pair of flat plate portions 37a formed in a plate-like shape and facing each other vertically, and a side plate portion 37b extending in the vertical direction Z and connecting right side Y2 edge portions of the pair of flat plate portions 37a. The member piece 37 covers the upper side Z1, the right side Y2, and the lower side Z2 of the electric wire 10. Of the member pieces 37 shown in FIG. 2 , the member piece 37 located on the vehicle body side X1 extends along the axial direction X. A restricting surface 37c constituting the edge portion of the door side X2 of the member piece 37 is substantially perpendicular to the axial direction X or inclined so as to be positioned closer to the vehicle body X1 as it extends toward the left side Y1. In contrast, the member piece 37 located on the door side X2 is inclined with respect to the axial direction X so that the door side X2 portion is positioned closer to the right side Y2. Therefore, a restricting surface 37d constituting the edge portion of the vehicle body side X1 of the member piece 37 on the door side X2 is inclined so as to be positioned closer to the door side X2 as it extends toward the left side Y1.
[0015] Due to this inclination, the restricting surface 37d faces the restricting surface 37c at an incline. This opposing relationship causes the restricting surfaces 37c and 37d to approach each other toward the right side (Y2) and to move farther apart toward the left side (Y1). The connecting portion 38 has a width in the up-down direction (Z) and is formed in a strip shape extending in the axial direction (X). The connecting portion 38 connects the side plate portion 37b of the member piece 37 on the vehicle body side (X1) to the side plate portion 37b of the member piece 37 on the door side (X2). The connecting portion 38 is elastically deformable in the width direction (Y). Therefore, when the wire 10 and the corrugated tube 20 are bent with the right side (Y2) facing inward from the main body portion 32 side, the connecting portion 38 bends with the right side (Y2) facing inward. In this case, the member piece 37 on the vehicle body side (X1) and the member piece 37 on the door side (X2) do not interfere with each other because the restricting surfaces 37c and 37d are displaced away from each other. Therefore, the wire 10 and the corrugated tube 20 are allowed to bend with the right side Y2 facing inward without being affected by the restricting portion .
[0016] On the other hand, when the electric wire 10 and the corrugated tube 20 are bent starting from the main body 32 side so that the left side Y1 faces inward, the connecting portion 38 bends with the left side Y1 facing inward. This bending causes the electric wire 10 and the corrugated tube 20 to bend a predetermined amount toward the left side Y1. However, at this time, the member piece 37 on the vehicle body side X1 and the member piece 37 on the door side X2 are displaced in a direction in which the restricting surfaces 37c and 37d approach each other, and eventually come into contact with each other. This contact causes interference between the member piece 37 on the vehicle body side X1 and the member piece 37 on the door side X2. This interference restricts further bending of the connecting portion 38 with the left side Y1 facing inward, and this restriction also restricts further bending of the electric wire 10 and the corrugated tube 20 with the left side Y1 facing inward.
[0017] Due to the configuration of the restricting portion 36, in this embodiment, as shown in FIG. 3A, bending of the wire 10 and the corrugated tube 20 with the right side Y2 facing inward is permitted. This state in which the wire 10 and the corrugated tube 20 are bent is referred to as a bent state. On the other hand, bending of the wire 10 and the corrugated tube 20 with the left side Y1 (predetermined direction) facing inward is permitted only to a predetermined amount. That is, bending of the wire 10 and the corrugated tube 20 with the left side Y1 (predetermined direction) facing inward is restricted to a predetermined amount or more. Here, in this embodiment, as an example, the right side Y2, in which bending is permitted, is referred to as the permitted direction, and the left side Y1, in which bending is restricted, is referred to as the restricted direction. However, since the restricting portion 36 is disposed inside the corrugated tube 20 as described above, it is difficult to recognize the permitted direction and the restricted direction after the wire harness 1 is completed. Therefore, as shown in FIG. 3B, the corrugated guide 30 is formed with a confirmation rib 39 (indicator portion) that allows the permitted direction and the restricted direction to be visually confirmed (recognized).
[0018] As shown in FIG. 2, the confirmation rib 39 is formed to protrude upward (Z1) from a position on the vehicle body side (X1) of the opposing surface 33 of the main body portion 32 to the right and extends in the axial direction (X). The end of the confirmation rib 39 on the vehicle body side (X1) is integral with the flange portion 34. In this embodiment, the confirmation rib 39 is located on the right side (Y2) of the center of the opposing surface 33, thereby indicating that the allowable direction is the right side (Y2) and the restrictive direction is the left side (Y1). This confirmation rib 39 is particularly referred to as a first rib 39a. Note that the allowable direction and restrictive direction of the bending direction of the electric wire 10 and the corrugated tube 20 can be changed by changing the orientation and arrangement of each component of the corrugated guide 30. FIG. 4(A) is a plan view of a corrugated guide 30′ of a wire harness 1′ having a bending direction different from that of the wire harness 1 shown in FIG. 1. FIG. 4(B) is a plan view of the wire harness 1′ including the corrugated guide 30′ shown in FIG. 4(A) from above.
[0019] As shown in Fig. 4(A), the corrugated guide 30' has the same configuration as the corrugated guide 30 described above, such as a main body 32 and a plurality of restricting portions 36, and these configurations are arranged in an orientation that is symmetrical to the corrugated guide 30 with respect to the axial direction X. Note that the configurations of the components of the corrugated guide 30' are the same as those of the corrugated guide 30 described above, and therefore the same reference numerals are used and their description will be omitted. Due to the shape of the corrugated guide 30', the wire harness 1' is allowed to bend with the left side Y1 of the electric wires 10' and the corrugated tube 20' facing inward, as shown in Fig. 4(B).
[0020] On the other hand, the wire 10′ and the corrugated tube 20′ are only allowed to bend inward toward the right side Y2 (predetermined direction) by a predetermined amount. That is, the wire 10′ and the corrugated tube 20′ are restricted from bending inward toward the right side Y2 (predetermined direction) by more than a predetermined amount. Therefore, for the wire 10′ and the corrugated tube 20′, the left side Y1, where bending is permitted, is the allowed direction, and the right side Y2, where bending is restricted, is the restricted direction. For this reason, the confirmation rib 39 of the corrugated guide 30′ shown in FIG. 4(A) is an indicator indicating that the allowed direction is the left side Y1 and the restricted direction is the right side Y2. This confirmation rib 39 is particularly referred to as the second rib 39b. The second rib 39b is formed to protrude upward toward the upper side Z1 from a position on the left side of the vehicle body side X1 of the opposing surface 33 of the main body portion 32 and extends in the axial direction X. The end of the second rib 39b on the vehicle body side X1 is integral with the flange portion 34.
[0021] Next, the rotor 40 will be described. As shown in FIG. 1, the rotor 40 is a component that houses and holds the corrugated guide 30. The rotor 40 is formed, for example, using a resin material and includes a first rotor cover 50 and a second rotor cover 60 that fit together. The first rotor cover 50 is a cover disposed on the lower side Z2 and includes a plate-shaped first base portion 51 extending in the axial direction X and a first side wall portion 52 extending from both ends of the first base portion 51 in the width direction Y to the upper side Z1. A first shaft portion 53 that protrudes toward the lower side Z2 is formed on the surface of the first base portion 51 facing the lower side Z2. The first shaft portion 53 is formed in a cylindrical shape. As shown in FIG. 5, a first side fixing rib 54 that protrudes toward the upper side Z1 and extends in the width direction Y is formed on the surface 51a of the first base portion 51 facing the upper side Z1. Two first side fixing ribs 54 are arranged at intervals in the width direction Y, and three first side fixing ribs 54 are arranged at intervals in the axial direction X. That is, a total of six first side fixing ribs 54 are formed.
[0022] The grooves between adjacent first side fixing ribs 54 in the axial direction X form tube locking portions 55, and the large diameter portions 21 of the corrugated tube 20 fit into and are locked into the tube locking portions 55. At this time, the first side fixing rib 54 fits between adjacent large diameter portions 21 of the corrugated tube 20 and abuts against the small diameter portions 22. As a result, the outer surface of the end portion of the corrugated tube 20 on the vehicle body side X1 engages with the inner surface of the rotor 40, and the corrugated tube 20 is fixed to the rotor 40. A flange fixing rib 56 that protrudes toward the upper side Z1 is formed on the vehicle body side X1 of the first side fixing rib 54 that is located furthest from the vehicle body side X1.
[0023] By forming the flange fixing rib 56, a fitting groove 57 is formed between the flange fixing rib 56 and the first side fixing rib 54 located closest to the vehicle body side X1. The flange portion 34 of the corrugated guide 30 fits into and is locked in the fitting groove 57. On the surface 51a facing the upper side Z1 of the first base portion 51, a substantially rectangular fitting hole 58 penetrating in the plate thickness direction is formed on the left side Y1 of the first side fixing rib 54 located on the left side Y1 and on the right side Y2 of the first side fixing rib 54 located on the right side Y2.
[0024] 1, the second rotor cover 60 is a cover disposed on the upper side Z1, and includes a plate-shaped second base portion 61 extending in the axial direction X, and second side wall portions 62 extending from both end edges of the second base portion 61 in the width direction Y to the lower side Z2. The dimension of the second base portion 61 in the width direction Y is set to be slightly smaller than the dimension of the first base portion 51 in the width direction Y. With this setting, the second rotor cover 60 fits into the first rotor cover 50 toward the lower side Z2, with the outer surface of the second side wall portion 62 aligned with the inner surface of the first side wall portion 52 of the first rotor cover 50.
[0025] A second shaft portion 63 that protrudes and extends toward the upper side Z1 is formed on the surface of the second base portion 61 facing the upper side Z1. The second shaft portion 63 is formed in a cylindrical shape. As shown in FIG. 6, a second side fixed rib 64 that protrudes toward the lower side Z2 and extends in the width direction Y is formed on the surface 61a of the second base portion 61 facing the lower side Z2. Two second side fixed ribs 64 are lined up with a gap in the width direction Y, and two second side fixed ribs 64 are lined up with a gap in the axial direction X. That is, a total of four second side fixed ribs 64 are formed. Of the multiple second side fixed ribs 64, the second side fixed rib 64 located on the vehicle body side X1 is disposed in the same position in the axial direction X as the above-mentioned flange fixed rib 56 (see FIG. 5).
[0026] With this arrangement, the surface of the second-side fixed rib 64 arranged on the vehicle body side X1 facing the door side X2 abuts against the surface of the flange portion 34 fitted in the fitting groove 57 facing the vehicle body side X1, thereby restricting displacement of the flange portion 34 toward the vehicle body side X1. Meanwhile, of the multiple second-side fixed ribs 64, the second-side fixed rib 64 located on the door side X2 is located at the same position in the axial direction X as the first-side fixed rib 54 (see FIG. 5) that is located furthest toward the door side X2 among the above-mentioned first-side fixed ribs 54. With this arrangement, the second-side fixed rib 64 located on the door side X2 fits between adjacent large-diameter portions 21 of the corrugated tube 20 and abuts against the small-diameter portion 22. Furthermore, a restricting rib 65 that protrudes downward Z2 and extends in the width direction Y is formed on the vehicle body side X1 of the second-side fixed rib 64 located on the vehicle body side X1. The restricting rib 65 is located closer to the vehicle body X1 than the tip of the protruding portion 35 of the corrugated guide 30 when the flange portion 34 of the corrugated guide 30 is engaged with the fitting groove 57.
[0027] With this arrangement, if a force that displaces the corrugated guide 30 toward the vehicle body side X1 is unintentionally applied to the corrugated guide 30, the protrusions 35 come into contact with the restricting ribs 65, thereby restricting the displacement of the corrugated guide 30 toward the vehicle body side X1. Therefore, the restricting ribs 65, together with the fitting grooves 57, function as positioning portions that determine the position of the corrugated guide 30. Fitting claws 66 that protrude toward the lower side Z2 are formed on both end edges in the width direction Y of the surface 61a of the second base portion 61 that faces the lower side Z2. When the second rotor cover 60 is fitted to the first rotor cover 50, the fitting claws 66 fit into the fitting holes 58 of the first rotor cover 50. This fitting causes the first rotor cover 50 and the second rotor cover 60 to become one unit.
[0028] A window 67 is formed in the center of the surface 61a of the second base portion 61 facing the lower side Z2, penetrating in the plate thickness direction. The window 67 is configured to allow the confirmation rib 39 to be visible from the outside. The window 67 is composed of a first window 67a that allows the first rib 39a to be visible and a second window 67b that allows the second rib 39b to be visible. By forming the window 67, the first rib 39a can be easily confirmed from the outside through the window 67 after the wire harness 1 is completed, as shown in FIGS. 3A and 3B. Furthermore, by forming the second window 67b in addition to the first window 67a, the second rib 39b can also be confirmed, as shown in FIG. 4B. That is, even when a corrugated guide 30' having a different restricting direction from that of the corrugated guide 30 is attached to the rotor 40, the restricting direction can be easily confirmed.
[0029] The wire harness 1 configured as described above is connected to the vehicle body and the sliding door by attaching the rotor 40 on the vehicle body side X1 to the vehicle body and the rotor on the door side X2 to the sliding door. The wire harness 1 bends in the width direction Y in accordance with the opening and closing of the sliding door. At this time, the rotor 40 is able to swing about the axes of the shafts (the first shaft 53 and the second shaft 63) extending in the up-down direction Z. This swinging allows the wire harness 1 to be displaced to an appropriate position in accordance with the opening and closing of the sliding door. The corrugated guide 30 also restricts the wires 10 and the corrugated tube 20 from bending more than a predetermined amount in a predetermined direction (in this embodiment, the left side Y1 in the width direction Y), thereby preventing the wire harness 1 from interfering with the vehicle body, for example.
[0030] According to the above-described embodiment, the wire harness 1 includes the electric wire 10, the corrugated tube 20 circumferentially covering the electric wire 10, and the corrugated guide 30 (restricting member) that restricts bending of the electric wire 10 and the corrugated tube 20 in the left side Y1 (predetermined direction). The wire harness 1 also includes a rotor 40 (holding member) that holds the corrugated guide 30. The corrugated guide 30 includes a restricting portion 36 that is disposed along the longitudinal direction of the electric wire 10 inside the corrugated tube 20 and restricts the electric wire 10 and the corrugated tube 20 from bending more than a predetermined amount in the width direction Y. The corrugated guide 30 also includes a held portion 31 that protrudes outward from an end of the corrugated tube 20 and is housed in the rotor 40. The held portion 31 is provided with a confirmation rib 39 (indicating portion) that allows the restricting direction to be recognized, and the rotor 40 is provided with a window portion 67 that allows the confirmation rib 39 to be visible from the outside.
[0031] According to this aspect of the invention, when the assembly of the wire harness 1 is completed, the following can be achieved. That is, the confirmation rib 39 can be easily visually confirmed from outside the rotor 40 through the window 67, and the restricted direction, which is the curvature direction of the electric wires 10 and the corrugated tube 20 restricted by the corrugated guide 30, can be easily confirmed. Therefore, it is not necessary to actually check the operation of curving the corrugated tube 20, etc., each time the wire harness 1 is assembled, and it is possible to provide a wire harness 1 in which the restricted curvature direction can be easily confirmed. Furthermore, with this configuration, by visually confirming the confirmation rib 39 through the window 67, the above-mentioned assembly omissions or incorrect assembly can be detected early without being overlooked. Therefore, the number of rework steps required for assembling structures related to the wire harness 1 can be minimized.
[0032] Furthermore, according to one aspect of the invention, by fitting the flange portion 34 of the main body portion 32 into the fitting groove 57 of the rotor 40, it is possible to prevent the corrugated guide 30 from shifting in position relative to the rotor 40. Therefore, even if vibrations or impacts are applied during transportation of the wire harness 1, it is possible to prevent the confirmation rib 39 from shifting in position, and the confirmation rib 39 can be reliably viewed through the window portion 67.
[0033] Furthermore, according to one aspect of the invention, the restriction direction restricted for each wire harness 1 can be easily confirmed by visually checking the first rib 39a through the first window 67a or the second rib 39b through the second window 67b. Therefore, for the electric wire 10 and the corrugated tube 20 (the electric wire 10' and the corrugated tube 20') having different restriction directions, the following can be done. That is, the rotor 40 corresponding to the plurality of wire harnesses 1 and 1' having different restriction directions can be standardized. Furthermore, even when this standardization is performed, it is easy to prevent incorrect assembly of the wire harnesses 1 and 1', and this standardization can reduce the manufacturing cost of the wire harnesses 1 and 1'.
[0034] According to another aspect of the present invention, a power supply device 100 can be provided that connects a vehicle body and a sliding door using a wire harness 1 whose restricted bending direction can be easily confirmed. In this case, since the holding member is configured as the rotor 40, the ends of the electric wire 10 and the corrugated tube 20 can be swung around an axis in accordance with the opening and closing of the sliding door. This swinging and the above-described bending of the electric wire 10 and the corrugated tube 20 can shape the electric wire 10 and the corrugated tube 20 appropriately. Furthermore, the electric wire 10 and the corrugated tube 20 can be displaced to appropriate positions. Therefore, the sliding door can be opened and closed smoothly.
[0035] The above-described embodiment merely illustrates one aspect of the wire harness 1 and the power supply device 100, and the embodiment is not limited thereto. For example, in the present embodiment, the allowable direction and the restricting direction of the bending direction of the wire harness 1 are set to the width direction Y. However, the allowable direction and the restricting direction may be set to various directions intersecting the axial direction X. In addition, in the above embodiment, the restricting portion 36 of the restricting member is exemplified as the restricting portion 36 of the corrugated guide 30, which is formed in a C-shape. However, the configuration of the restricting member is not limited thereto. For example, one flat portion 37a may be omitted from the restricting portion 36 to form an L-shape, and this L-shaped restricting portion may serve as the restricting portion 36. Furthermore, the restricting portion 36 may be formed using a binding cord, a tie wrap, tape, or the like. In this case, the corrugated tube 20 may be omitted.
[0036] In the above description, specific shapes of each component, such as a rectangular protrusion (protrusion 35), a substantially rectangular fitting hole 58, and a band-shaped connecting portion 38, are described. However, the terms "shape" and "shape" are merely examples of the present invention. The components of these components may have any shape as long as they function similarly to the corresponding components of the above-described embodiments. That is, the protrusion 35 may be a cylindrical protrusion, the fitting hole 58 may be a substantially circular hole, or the connecting portion 38 may be a rod-shaped member. In the above embodiment, the main body 32 and the restricting portion 36 of the corrugated guide 30 are integrally molded from a resin material. However, the corrugated guide 30 may be formed by connecting, for example, multiple resin pieces and a flexible connecting portion made of a metal leaf spring by screwing, adhesive fixing, insert molding, or the like.
[0037] Furthermore, the window portion 67 may not be configured with the first window portion 67a and the second window portion 67b that are independent of each other, but may be configured as a single window portion 67 that connects the first window portion 67a and the second window portion 67b. This window portion 67 may then function as the first window portion 67a and the second window portion 67b. Furthermore, the wire harness 1 has been described as a part of the power supply device 100 that connects a power source on the vehicle body side to an electrical device on the sliding door side, but the use of the wire harness 1 is not limited to this. In other words, the wire harness 1 can be applied to various structures that require connecting various parts together while restricting bending in a predetermined direction. [Explanation of symbols]
