{First embodiment}
The wire harness according to the first embodiment will be described. This embodiment demonstrates the form which embed | buried the linear member in the protection cylinder part. FIG. 1 is a schematic perspective view showing a mounting portion of the protective cylinder portion 30 of the wire harness 10, FIG. 2 is a schematic front view showing the mounting portion, and FIG. 3 is arranged and fixed to the vehicle. It is explanatory drawing which shows a state.

  The wire harness 10 includes a wire harness main body 12, a linear member 20, and a protective cylinder portion 30.

  The wire harness main body 12 is configured by binding a plurality of electric wires. More specifically, the wire harness main body 12 has a configuration in which a plurality of electric wires are bundled while being branched according to a wiring form to a vehicle to be arranged. In FIG. 1 etc., the linear path | route control part 14 is shown among the wire harness main-body parts 12. FIG. But the wire harness main-body part 12 may be comprised with the single electric wire which does not necessarily need to branch. Further, another optical cable or the like may be bound to the wire harness main body 12. The linear member 20 and the protection cylinder part 30 are arrange | positioned in the path | route control part 14 which is a part of this wire harness main-body part 12. As shown in FIG. In addition, the path | route control part 14 should just be at least one part of the wire harness main-body part 12, and may be a part of the wire-harness main-body part 12, or the whole.

  The linear member 20 is formed into a member that can be plastically deformed and that maintains the path regulating portion 14 and the protective cylinder part 30 in a shape along a certain path after plastic deformation. As the linear member 20, a metal wire such as an iron wire, a copper wire, a stainless steel wire, or an alloy wire thereof, or a resin that exhibits a certain degree of rigidity after plastic deformation can be used. There may be at least one linear member 20, and in this embodiment, two linear members 20 are provided on the outer periphery of the route restriction portion 14 so as to sandwich the central axis of the route restriction portion 14.

  In order for the linear member 20 to maintain the path regulating portion 14 in a shape after bending deformation, it is necessary to have a certain degree of rigidity after bending deformation due to plastic deformation. Usually, one or a plurality of (two in the present embodiment) linear members 20 disposed in the path restriction portion 14 as a whole are route restriction portions 14 and protective cylinders of the wire harness main body 12 after bending deformation. It is preferable that the portion 30 has rigidity exceeding a force for returning to the original shape. Thus, the rigidity that each linear member 20 should have after plastic deformation is the material, thickness, and number of the linear member 20, and the thickness, the number of wires, and the wire material of the path restriction portion 14 to be regulated. These are set experimentally and empirically in accordance with the regulated shape (bending deformation amount), the material of the protective cylinder portion 30, the thickness, and the like. For example, when the route restriction portion 14 to be restricted is thick and the number of electric wires is large, the force that the route restriction portion 14 after bending deformation tries to return to becomes large. In such a case, the linear member 20 may be made of a material having greater rigidity or a large diameter, or a large number of linear members 20 may be used.

  The protective cylinder 30 is formed in a cylindrical shape that can be bent and covers the path restricting portion 14. Here, the protection cylinder part 30 is a member which exhibits a cylinder shape in the state before covering the path | route control part 14. FIG. More specifically, the protective cylinder part 30 is constituted by a so-called corrugated tube in which a large diameter part 32a and a small diameter part 32b are alternately connected via a step part. Since the protective cylinder portion 30 is easily elastically deformed at a step portion between the large diameter portion 32a and the small diameter portion 32b, it has a property of being easily bent and deformed as a whole. In addition, the protection cylinder part 30 should just have the property of the grade which can be bent and deformed by human power, such as an operator.

  A split groove 31 is formed on one side of the protective cylinder 30 along the extending direction. Then, the protective cylinder part 30 is split open by the split groove 31 so that the path restricting portion 14 of the wire harness main body part 12 can be easily arranged in the protective cylinder part 30. A tie band or an adhesive tape is wound around the outer periphery of the protective cylinder part 30 in a state where the path restricting portion 14 of the wire harness main body part 12 is disposed in the protective cylinder part 30, thereby the protective cylinder part 30. Maintains the state of covering the path restricting portion 14 of the wire harness main body 12. The split groove 31 of the protection cylinder part 30 may be maintained in a closed state by another lock structure or the like.

  In addition, the protection cylinder part does not need to be the above corrugated tubes, The cylinder shape etc. with which the same diameter part continues along a longitudinal direction may be sufficient. For example, heat-resistant pipes such as PVC (polyvinyl chloride) tubes, PVC split tubes (one side of the PVC tube cut along the extending direction), vinyl tubes, Irax tubes (trademark), etc. A tube, a glass varnish tube, a polyethylene tube, a heat shrinkable tube, or the like can be used. When a heat-shrinkable tube is used as the protective cylinder, the path-restricting part and the linear member are inserted into the heat-shrinkable tube before heat-shrinking, and the heat-shrinkable tube is heat-shrinked in this state, The structure which clamp | tightens and integrates a linear member may be sufficient. Further, for example, the protective cylinder portion may be a member formed of an elastomer such as rubber, for example, a rubber member such as a grommet formed of rubber or the like, or a member formed in a bellows tubular shape by rubber or the like.

  The linear member 20 is fixed to the protective cylinder part 30 in a posture along the extending direction of the protective cylinder part 30. Here, the linear member 20 is embedded in the protective cylinder portion 30. More specifically, a ridge 34 is formed on the side of the protective cylinder 30 along the extending direction. The protruding portion 34 is formed in an elongated protruding portion extending along the extending direction of the protective cylinder portion 30 so as to eliminate the unevenness difference between the large diameter portion 32a and the small diameter portion 32b. The linear member 20 is embedded in the ridge 34. The linear member 20 does not need to be completely embedded in the protective cylinder portion 30. The linear member 20 may be partially exposed as long as the linear member 20 can be fixed to the protective cylinder portion 30.

  For example, the linear member 20 can be embedded in the linear member 20 by insert molding when the protective cylinder 30 is molded. For example, when the molten resin is extruded into a cylindrical shape and vacuumed with a vacuum mold or the like to form the protective cylinder 30, the linear member 20 is combined with the molten resin extruded into a cylindrical shape. It is good to extrude and embed the said linear member 20 in the molten resin extruded to a cylindrical shape, and to vacuum-mold this. Alternatively, the molten resin extruded into a cylindrical shape may be sucked and molded into a vacuum mold in which the linear member 20 is disposed.

  The protection cylinder part 30 (protection cylinder part with a linear member) to which the linear member 20 is fixed as described above is attached and fixed to the path regulation part 14 of the wire harness main body part 12 as follows. That is, the path regulating portion 14 of the wire harness main body 12 is disposed in the protective cylinder 30 so that the protective cylinder 30 is split by the split groove 31 of the protective cylinder 30. Thereafter, a tie band is attached to the outer periphery of the protective cylinder part 30 or an adhesive tape is wound around the protective cylinder part 30 so as to prevent the protective cylinder part 30 from opening. At this time, preferably, an adhesive tape or the like is wound around the end portion of the protective cylinder portion 30 and a part of the wire harness main body portion 12 extending from the end portion, so that a part of the protective cylinder portion 30 and the wire harness main body portion 12 is provided. Are positioned and fixed along the extending direction. Further, if necessary, a vehicle fixing component 50 for fixing to the vehicle body 60 is attached and fixed to the outer periphery of the protective cylinder portion 30 (see FIG. 3, see a fixture 340B of a fourth embodiment described later on the vehicle body fixing component). ). The vehicle fixing component 50 is, for example, a component in which a clamp portion 52 that can be inserted and fixed in an attachment hole 60 h to the vehicle body 60 and a tie band portion 54 that can be wound and fixed to the outer peripheral portion of the protective cylinder portion 30 are integrated. is there. Here, the vehicle fixing component 50 is fixed to one end of the protective cylinder 30.

  The handling of the linear member 20 from the manufacturing stage of the wire harness 10 to the stage of assembling the wire harness 10 to the vehicle body 60 will be described.

  First, in order to simplify the wire harness assembly drawing board and the manufacturing process as much as possible, it is preferable to arrange the wire harness main body 12 in a straight line at the stage of manufacturing the wire harness 10 without bending. For this reason, it is preferable to attach the protection cylinder part 30 and the linear member 20 to the said path | route control part 14 in the state which arrange | positioned the path | route control part 14 of the wire harness 10 linearly.

  In the storage and transportation stage until the wire harness 10 is manufactured and assembled to the vehicle body 60, it is preferable that the wire harness 10 is made as small as possible so that the accommodation number per unit volume can be increased as much as possible. For this reason, it is preferable that the path restricting portion 14 of the wire harness 10 is arranged in a straight line so that a large number of wire harnesses 10 can be stacked and accommodated even in the storage and transport stages.

  When assembling the wire harness 10 to the vehicle body 60, the operator bends and deforms the route restriction portion 14 of the wire harness 10 by human power or the like according to the arrangement route of the wire harness 10 in the vehicle body 60. For example, as shown in FIG. 13, in the vehicle body 60, when an arrangement path 62 that is surrounded and bent by the portions 60a and 60b is formed, a shape corresponding to the arrangement path 62 (here, substantially Z-shaped) ), The path regulating portion 14 is bent and deformed together with the protective cylinder portion 30 and the linear member 20. Then, the path restriction portion 14 of the wire harness 10 is maintained in a shape corresponding to the path restriction portion 14 due to the rigidity of the linear member 20. Then, the wire harness 10 is fixed to the vehicle body 60 by inserting and fixing the clamp portion 52 of the vehicle fixing component 50 fixed to the wire harness 10 arranged in the arrangement path 62 into the mounting hole 60h of the vehicle body 60. .

  Thus, in the state where the wire harness 10 is fixed to the vehicle body 60, the path restricting portion 14 of the wire harness 10 is maintained in a certain bent state by the linear member 20, and therefore, contact with the vehicle body side portions 60a and 60b. Is suppressed. Further, the route restriction portion 14 is also surrounded by the protective cylinder portion 30, so that direct contact with the vehicle body side portions 60 a and 60 b is suppressed.

  According to the wire harness 10 and the protective cylinder with a linear member configured as described above, the path regulating portion 14 and the linear member 20 of the wire harness main body 12 can be bent and deformed according to a desired path shape. it can. When these are bent and deformed, the path regulating portion 14 can be maintained in the shape after the bending deformation by the rigidity of the linear member 20, and the bending can be regulated for the wiring paths having various shapes. For this reason, unlike the structure using the conventional protector, it is not necessary to design and start a mold according to each wiring route and to manufacture a protector which is a resin molded product having a shape according to the route. For this reason, the path | route regulation of the wire harness main-body part 12 can be performed as low-cost as possible. But even if the protector similar to the past is used in a part of wire harness 10, there is no problem.

  Further, when a conventional protector is used, a dedicated drawing board or the like for bending the path restricting portion 14 of the wire harness 10 to be accommodated in the protector may be required in the manufacturing stage of the wire harness 10. On the other hand, since the said protection cylinder part 30 and the linear member 20 can be easily assembled | attached with respect to the wire harness 10 of a linear state, there is no need of the drawing board in which such special consideration was made. . This also contributes to cost reduction of the wire harness 10. In addition, the wire harness 10 to which the protective cylinder portion 30 and the linear member 20 are applied can be stored and transported in a state where the path regulating portion 14 is in a straight line, so that the accommodation efficiency and the transport efficiency can be improved. .

  Moreover, the linear member 20 can be arrange | positioned along the path | route control part 14 by attaching the protection cylinder part 30 to the path | route control part 14, and those attachment work becomes easy. And since the linear member 20 is embed | buried and integrated in the said protection cylinder part 30, the protection cylinder part with a linear member can be handled as one component.

  4 and 5 are diagrams showing a modification according to the embodiment.

  That is, in the said embodiment, although the protective cylinder part 30 demonstrated that it was a member which exhibits a cylindrical shape in the state before covering the path | route control part 14, it is not necessarily the case. In this modification, the protective cylinder portion 30 </ b> B is a sheet-like member in a state before covering the path restriction portion 14, and has a cylindrical shape in a state where the path restriction portion 14 is covered.

  That is, the protective cylinder 30B is a sheet-shaped member 30Ba that can be bent and formed of polyvinyl chloride, urethane, or the like before being wound around the path regulating portion 14. The sheet-like member 30Ba has a spread that can be wound in a state of covering the entire path regulating portion 14 at least once. Here, the sheet-like member 30Ba has a rectangular sheet shape, but is not necessarily required, and may be another polygonal shape or a circular sheet shape. Further, the linear member 20 is embedded in one side portion of the sheet-like member 30Ba. The configuration in which the linear member 20 is embedded in the sheet-like member 30Ba can be realized, for example, by extruding the linear member 20 together with the resin forming the sheet-like member 30Ba when the sheet-like member 30Ba is extruded. . The linear member 20 may be embedded in an intermediate portion instead of one side portion of the sheet-like member 30Ba. A plurality of linear members 20 may be embedded in the sheet-like member 30Ba.

  In addition, a joint portion 30Bb such as an adhesive layer is provided on one main surface of the other side of the sheet-like member 30Ba (see a region with a mesh line in FIG. 4). Then, in a state where the path regulating portion 14 is disposed along one side of the sheet-like member 30Ba, the other side of the sheet-like member 30Ba is covered with the path regulating portion 14 so that the sheet-like member 30Ba is covered with the path regulating portion. 14 Then, when the joining portion 30Bb is fixed to the outer peripheral surface of the sheet-like member 30Ba, a protective cylinder portion 30B having a cylindrical shape is formed in a state of covering the path restricting portion 14. The tubular shape may be maintained as the protective tubular portion 30B by wrapping an adhesive tape or the like around the tubular outer periphery of the sheet-like member 30Ba covering the route restricting portion 14.

  Also in this modified example, the path regulating portion 14, the linear member 20, and the protective cylinder portion 30B are bent and deformed according to a desired path shape, and then the linear member 20 as described in the above embodiment. Due to the rigidity, the path regulating portion 14 can be maintained in the shape after bending deformation. For this reason, the path | route regulation of the wire harness 10 can be performed at as low a cost as possible.

{Second Embodiment}
A wire harness according to the second embodiment will be described. This embodiment demonstrates the form which inserted and fixed the linear member in the clamping part formed in the protection cylinder part. FIG. 6 is a schematic perspective view showing a mounting portion of the protective cylinder 130 in the wire harness 110, and FIG. 7 is a schematic front view showing the mounting portion. In the description of the present embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The wire harness 110 includes a wire harness main body 12, a linear member 20, and a protective cylinder 130.

  Similarly to the protective cylinder part 30, the protective cylinder part 130 includes a cylindrical main body part 132 formed in a so-called corrugated tube shape in which a large diameter part 132a and a small diameter part 132b are alternately connected via a step part. Have. However, as described in the above embodiment, the cylinder main body 132 does not have to be formed in the shape of a corrugated tube, and may be a cylinder member formed of an elastomer such as another resin tube or rubber. . The protection cylinder part 130 should just be formed with the material which can maintain the shape of the clamping part 134. FIG.

  A clamping part 134 is formed on the outer periphery of the tube main body part 132. The sandwiching portion 134 is configured to be able to sandwich and fix the linear member 20. Here, the clamping part 134 is supporting the linear member 20 in the fixed position along the circumferential direction of the cylinder main-body part 132. FIG. Further, in the extending direction of the linear member 20, the sandwiching portion 134 supports the linear member 20 with a force that allows movement of the linear member 20 by applying a force in that direction. ing.

  More specifically, the sandwiching portion 134 has a protruding shape that protrudes outward from the outer periphery of the tube main body 132, and is formed to extend along the extending direction of the tube main body 132. The sandwiching part 134 has a pair of sandwiching pieces 135 disposed adjacent to each other, and the linear member 20 can be disposed on the inward portion of the base end part 135a of the pair of sandwiching pieces 135. A sandwiching recess 135b is formed. Here, the base end portion 135a is formed in a lateral V-shape with the bent portion facing outward, so that the sandwiching recess 135b is formed in the inward portion, but the shape is not necessarily required. Moreover, it forms in the guide surface 135d which inclines so that the inward surface of the front-end | tip part 135c of a pair of clamping piece 135 may spread sequentially toward outward. Here, the guide surface 135d is formed by forming the entire distal end portion 135c into a shape that expands outward, but the shape is not necessarily required.

  The linear member 20 is fixed by the holding portion 134 as follows. That is, the linear member 20 is pushed between the pair of holding pieces 135 while being pressed against the pair of guide surfaces 135d. Thereby, the pair of sandwiching pieces 135 are elastically deformed so as to open, and the linear member 20 is disposed in the pair of sandwiching recesses 135b. Thereafter, when the pair of sandwiching pieces 135 are closed by elastic restoring force, the linear member 20 is sandwiched by the pair of sandwiching pieces 135, and the linear member 20 is fixed to the cylinder main body portion 132 via the sandwiching portion 134. .

  Note that a plurality of the holding portions 134 and the linear members 20 may be provided around the tube main body portion 132. In the present embodiment, the sandwiching portion 134 and the linear member 20 are provided at two locations facing each other around the tube main body portion 132.

  Also by the wire harness 110 and the protective cylinder portion 130 with a linear member according to the second embodiment, the path regulating portion 14 and the linear member 20 of the wire harness main body 12 are bent and deformed according to a desired path shape, Thereafter, the path regulating portion 14 can be maintained in the shape after bending deformation by the rigidity of the linear member 20. For this reason, the path | route regulation of the wire harness main-body part 12 can be performed as low-cost as possible similarly to the said 1st Embodiment.

  Further, according to the wire harness 110 and the protective cylinder portion 130 with a linear member according to the second embodiment, the linear member 20 is supported in a state of being movable along the longitudinal direction with respect to the sandwiching portion 134. Therefore, when the protective cylinder part 130 is bent, the position of the linear member 20 in the longitudinal direction with respect to the cylinder main body part 132 can be adjusted. For this reason, the protection cylinder part 130 can be bent smoothly. This effect will be described in more detail in the following modification.

  8 and 9 are diagrams showing a modification according to the present embodiment.

  That is, in the said embodiment, although the clamping part 134 was formed so that it might extend continuously along the extension direction on the outer periphery of the cylinder main body part 132, it is not necessarily required. In the protective cylinder part 130B according to this modification, a plurality of clamping parts 134B are provided on the outer periphery of the cylinder main body part 132 at intervals along the extending direction thereof. Each sandwiching part 134B is configured to be fixed so as to sandwich the linear member 20 with the same configuration as the sandwiching part 134. In this modification, an example is shown in which five sandwiching portions 134B are provided along the extending direction of the tube main body 132, but the number thereof is appropriately determined depending on the length of the tube main body 132, the degree of bending, and the like. Is set.

  Each clamping part 134B may be a part of the clamping part 134 that has been partially excised, or may be a part that has been molded from the beginning.

  Also by this modification, the same effect as the above embodiment can be obtained. In addition, since the clamping part 134B is provided with a gap along the extending direction of the tube main body part 132, the linear member 20 can easily move along the longitudinal direction with respect to the clamping part 134B. . For this reason, for example, when the protective cylinder portion 130B is bent so as to draw a gentle S-shape, the length dimension L1 of the linear member 20 disposed along the inner portion is the inner portion of the bent portion. The linear member 20 can be moved along the longitudinal direction with respect to the sandwiching portion 134B so as to be shortened (see arrow A1). On the other hand, in the outer portion of the bent portion, the linear member 20 is placed in the longitudinal direction with respect to the sandwiching portion 134B so that the length dimension L2 of the linear member 20 disposed along the outer portion becomes longer. Can be moved along (see arrow A2). For this reason, while moving the linear member 20 along the extending direction of the cylinder main body 132 according to the length dimension of the inner part of the bending deformation portion of the protective cylinder part 130B, the length dimension of the outer part, etc. The protective cylinder part 130B can be bent, and the protective cylinder part 130B can be smoothly bent and deformed.

  In addition, this effect can be acquired also by the above-mentioned protection cylinder part 130. FIG. But since the protection cylinder part 130B which concerns on this modification can support the linear member 20 so that it can move more freely along the longitudinal direction, it can bend and deform the protection cylinder part 130B more smoothly. it can.

  Note that the sandwiching portions 134 and 134B may be provided on the inner peripheral side of the tube main body portion 132.

  Further, the sandwiching portions 134 and 134B are in a sheet shape that can be bent and deformed before being wound around the route restricting portion 14, and are cylinders that cover the route restricting portion while being wound around the route restricting portion 14.

{Third embodiment}
A wire harness according to the third embodiment will be described. This embodiment demonstrates the form which fixed the linear member to the path | route control part with the fixing tape wound around the outer periphery of the protection cylinder part. FIG. 10 is a schematic perspective view showing a mounting portion of the protective cylinder portion 230 in the wire harness 210. In the description of the present embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  That is, the protective cylinder part 230 is formed in a so-called corrugated tube shape, like the protective cylinder part 30, in which a large diameter part 232 a and a small diameter part 232 b are alternately connected via a step part. As described in the above embodiment, the protective cylinder portion 230 does not need to be formed in the shape of a corrugated tube, but is a resin member, a shrinkable tube by heat, a cylindrical member formed by an elastomer such as rubber, or the like. There may be.

  On the outer periphery of the protective cylinder part 230, the linear member 20 is disposed along the extending direction of the protective cylinder part 230. There may be one or more linear members 20. Here, two linear members 20 are provided on the outer periphery of the protective cylinder part 230 so as to sandwich the central axis of the protective cylinder part 230.

  A fixing tape 240 is wound around the protective cylinder 230 and the linear member 20 disposed on the outer periphery thereof. As the fixing tape 240, an adhesive tape or a self-bonding tape is used. The fixing tape 240 may be configured to be wound with a gap (so-called rough winding) without being overlapped in the width direction, or may be wound while being partially overlapped in the width direction. (So-called half wrap winding) may be used. Alternatively, the fixing tape 240 may be separately wound at a plurality of locations along the longitudinal direction of the protective cylinder 230, and the linear member 20 may be separately fixed to the protective cylinder 230. That is, the fixing tape 240 may be wound around the protective cylinder part 230 and the linear member 20 so as to fix the linear member 20 to the protective cylinder part 230.

  According to the wire harness 210 according to the third embodiment, the path regulating portion 14 and the linear member 20 of the wire harness main body 12 are bent and deformed according to a desired path shape, and then the rigidity of the linear member 20 is increased. The path regulating portion 14 can be maintained in the shape after bending deformation. For this reason, the path | route regulation of the wire harness main-body part 12 can be performed as low-cost as possible similarly to the said 1st Embodiment.

  That is, the protective cylinder portion 230B is a sheet-like member 230Ba that can be bent and deformed, which is formed of polyvinyl chloride, urethane, or the like before being wound around the path regulating portion 14. The sheet-like member 230Ba has the same configuration as that of the sheet-like member 30Ba described in the modification of the first embodiment except that the linear member 20 is not embedded.

  And after winding sheet-like member 230Ba around the path | route control part 14 and forming in the cylindrical protection cylinder part 230B, the linear member 20 follows the extension direction of the protection cylinder part 230B on the outer periphery of the said protection cylinder part 230B. Arranged. And the fixing tape 240 is wound around the outer periphery similarly to the above, and, thereby, the linear member 20 is being fixed with respect to the protection cylinder part 230B. The fixing tape 240 can not only fix the linear member 20 to the protective cylinder portion 230B, but can also serve to maintain the shape in which the sheet-like member 230Ba is wound around the path regulating portion 14.

  Also in this modified example, the path regulating portion 14, the linear member 20, and the protective cylinder portion 30B are bent and deformed according to a desired path shape, and then the linear member 20 as described in the above embodiment. Due to the rigidity, the path regulating portion 14 can be maintained in the shape after bending deformation. For this reason, the path | route regulation of the wire harness 10 can be performed at as low a cost as possible.

  In addition, the said linear member 20 may be provided in the inner peripheral side of the protection cylinder parts 230 and 230B. In this case, the linear member 20 may be disposed inside the path regulating portion 14 or may be disposed on the outer periphery thereof.

The engaged portion 349 includes a pair of side wall portions 349a projecting on both sides of the outer surface of the other end portion of the arc-shaped portion 344, and a retaining piece 349b formed so as to span between the tip portions of the pair of side wall portions 349a. The engaging portion 348 is inserted into the hole portion 349h surrounded by the other end portion of the arc-shaped portion 344, the pair of side wall portions 349a, and the retaining piece 349b. Further, when the engaging portion 348 is inserted into the engaged portion 349 and the protruding portion 348b exceeds the retaining piece 349b, the projecting portion 348b is retained and locked to the retaining piece 349b. Thereby, the other end portions of the pair of arc-shaped portions 343 and 344 are connected and fixed, and the pair of arc-shaped portions 343 and 344 maintain an annular shape surrounding the protective cylinder portion 330.

  And the protection cylinder part 330 and the linear member 20 are arrange | positioned between a pair of open arc-shaped parts 343,344. Thereafter, while the linear member 20 is disposed in the groove portions 343g and 344g, the pair of arc-shaped portions 343 and 344 are closed, and the engaging portion 348 and the engaged portion 349 are connected and fixed. As a result, the fixing member 340 is mounted around the protective cylinder 330 so as to fix the linear member 20 to the outer periphery of the protective cylinder 330.

  The fixed main body portion 342B is configured to be deformable from a state in which the protective cylinder portion 330 can be disposed inside to a state in which the protective cylinder portion 330 is surrounded. More specifically, the fixed main body portion 342B is formed in an elastically deformable belt shape, and the protective cylinder portion 330 can be disposed therein in a state of drawing a straight line or a relatively large arc. In a state of being deformed in an annular shape, it can be deformed so as to surround the protective cylinder portion 330.

  The engaged portion 349B is formed at one end portion of the fixed main body portion 342B. Here, the engaged portion 349B is formed in a substantially rectangular parallelepiped shape, and a hole portion 349Bh into which the fixed main body portion 342B can be inserted is formed. A projecting portion 349Ba that can be engaged with the engaging portion 348B is formed on the inner peripheral portion of the hole portion 349Bh. Further, the fixed main body portion 342B extends from one end portion of the engaged portion 349B.

  The engaging portion 348B is formed in a ridge shape extending in the width direction on one main surface (outer surface) of the other end portion of the fixed main body portion 342B. A plurality of engaging portions 348B are formed at intervals along the extending direction of the fixed main body portion 342B, and each engaging portion 348B can be engaged with the engaged portion 349B.

  Groove portions 349Bg and 342Bg in which the linear member 20 can be disposed are formed on one main surface of the engaged portion 349B and the fixed main body portion 342B (portion facing the inner periphery in a state of surrounding the protective cylinder portion 330). Has been. Here, the number of the groove portions 349Bg and 342Bg may be one or more depending on the number of the linear members 20 arranged. The groove portions 349Bg and 342Bg may be omitted.

{Modifications}
In addition, the structure which arrange | positions a linear member along a wire harness main-body part is not restricted to the said example. That is, if the path restriction part of the wire harness main body part is covered with the protection cylinder part and the linear member is disposed along the extending direction of the protection cylinder part, the path restriction part is formed by the protection cylinder part. While protecting, it is possible to regulate the path of the wire harness at as low a cost as possible. For example, the linear member may be provided inside the protective cylinder part itself (see the first embodiment), or may be provided on either the inner peripheral side or the outer peripheral side of the protective cylinder part. Further, the linear member does not need to be directly fixed to the protective cylinder portion. For example, even if the linear member is disposed inside the wire member so as to be surrounded by the electric wire constituting the route restricting portion. Good.

  Moreover, in the said embodiment, although the linear member is provided over the whole extension direction of a protection cylinder part, it is not necessarily required. When route regulation is requested for a part of the wire harness main body part covered by the protective cylinder part, a linear member may be provided only in the part.

  Further, the protective cylinder portion itself may be omitted in a portion where protection is not necessarily required. In this case, for example, the electric wire and the linear member constituting the path restriction portion of the wire harness main body are combined together (the linear member may be inside or outside the path restriction portion). What is necessary is just to bind by fixing tapes, such as an adhesive tape, or binding tools, such as a tie band. That is, if a linear member is disposed and attached to the route restriction portion of the wire harness main body along the extending direction, the route of the wire harness can be restricted as low as possible. In this case, the linear member may be a member that can be plastically deformed and exhibits rigidity that can maintain the path restriction portion in a shape along a certain path after plastic deformation.

  Further, the linear member meanders or skews with respect to the axial direction of the path regulating portion or the protective cylinder portion in a state of being arranged along the extending direction of the path regulating portion or the protective cylinder portion. It may be.

  In addition, each structure demonstrated by each said embodiment and each modification can be suitably combined unless it mutually contradicts. For example, in the longitudinal direction of the protective cylinder portion, a configuration in which the linear member is embedded, a configuration in which the linear member is sandwiched and fixed, and a configuration in which the linear member is fixed with a fixing tape or a fixture may be combined.
