Description

  The present invention relates to a harness routing structure for routing, for example, a wire harness for power feeding from a sliding door of an automobile to a vehicle body without interference, and a power feeding device including the same.

  6 to 7 show an embodiment of a conventional harness wiring structure and a power supply device including the same (see Patent Document 1).

  This power supply device 61 is for a sliding door of an automobile, and has a horizontally long guide member 63 provided on the sliding door 62, a slider 64 slidably engaged with a rail portion of the guide member 63, and a vertical to the slider 64. A swinging member 65 (FIG. 7) supported in such a manner as to be swingable in a horizontal direction by a shaft portion, and bent and arranged in a substantially U shape inside the guide member 63. From the swinging member 65 to the vehicle body ( And a caterpillar-shaped harness exterior member 66 made of a synthetic resin, which is arranged so as to be bent over (not shown).

  The exterior member 66 is covered with a tube 67 between the slide door 62 and the vehicle body (crossover portion). A plurality of electric wires (wire harnesses) 68 (FIG. 7) are inserted inside the exterior member 66 and the slider 64.

By opening the slide door 62 in the direction of arrow A (rear of the vehicle) from the state of FIG. 6, the slider 64 moves relative to the front along the guide member 63, and the wire harness 68 and the exterior member 66 move inside the guide member 63. Elongates in an approximate J shape. When the sliding door 62 is opened and closed, the wire harness 68 expands and contracts together with the exterior member 66, so that the harness surplus length is absorbed.
Japanese Patent Laying-Open No. 2003-25850 (FIGS. 2 and 4)

  However, the conventional harness wiring structure and the power supply device 61 including the same have a problem that the cost is high because the caterpillar-shaped exterior member 66 is complicated and expensive.

  Therefore, a power supply device for a sliding door using an inexpensive synthetic resin protective tube as an exterior member of a wire harness was examined. In that case, the protective tube can be bent in any direction (direction restricting property). Therefore, there is a concern that the protective tube may interfere with the vehicle body when the sliding door (62) is fully opened and may be rubbed or damaged.

  Further, in the embodiment shown in FIG. 7, there is a concern that the durability of the wire harness 68 may be lowered because the upper and lower harness portions are bent or twisted in a substantially V shape with the slider 64 as a fulcrum.

  Each of the above-mentioned concerns is not limited to the slide door (62) of the automobile, but also when the power supply apparatus is applied to a slide structure such as a slide door of a vehicle other than an automobile or a slide door of a processing machine. It can happen.

  In view of the above points, the present invention eliminates the concern of causing interference between the protective tube and the vehicle body when the slide structure is fully opened when an inexpensive protective tube is used as the exterior member of the wire harness. It is an object of the present invention to provide a harness wiring structure with good durability and a power supply device including the same.

  In order to achieve the above object, a harness routing structure according to claim 1 of the present invention includes a guide rail disposed on a slide structure, a slider slidably engaged with the guide rail, and the wire harness extending from the slider. In the harness routing structure in which the wire harness is routed to the fixed structure, the wire harness is inclined so as to be gradually separated from the fixed structure and is led out from the slider in the sliding structure opening direction, and is folded and fixed. It is routed on the structure side.

  With the above configuration, the wire harness is inclined from the slider toward the outside of the fixed structure, so that the folded portion of the wire harness is separated from the fixed structure when the slide structure is fully opened. Thus, interference between the wire harness and the fixed structure is prevented. In addition, since the wire harness is bent while being bent outward from the slider with a large radius, the bending stress applied to the bent portion of the wire harness is reduced. Further, since the wire harness is inclined outward, the wire harness is pressed against the slide structure side (guide rail side), and the swing trajectory of the wire harness is stabilized with the fixed structure when the slide structure is opened and closed. . For example, an automobile slide door is used as a slide structure, and a vehicle body is used as a fixed structure. The guide rail may be arranged in the case or may be arranged directly on the slide structure.

  The harness routing structure according to claim 2 is characterized in that, in the harness routing structure according to claim 1, the guide rail is arranged so as to be gradually separated from the fixed structure in the sliding structure opening direction. And

  With the above configuration, the slider is disposed to be inclined outward along the inclination of the guide rail (inclination that gradually separates from the slide structure), whereby the wire harness is gradually separated from the fixed structure. And is derived from the slider. Since the guide rail itself is inclined outward, the slider is positioned at one end side (end in the closing direction) of the guide rail when the slide structure is opened, and the other end side (end in the opening direction) of the guide rail when closed. And the slider moves away from the fixed structure when closed, so that interference between the wire harness and the fixed structure when closed is also prevented. Further, since the guide rail is inclined outward, the force with which the wire harness is pressed outward (on the slide structure side) is increased, and the swing trajectory of the wire harness is further stabilized when the slide structure is opened and closed. The shape of the guide rail is not limited to a linear shape, and may be, for example, a substantially corrugated shape or a substantially crank shape including front and rear straight portions and an intermediate inclined portion.

  The harness routing structure according to claim 3 is characterized in that, in the harness routing structure according to claim 1, the wire harness is routed on the slider so as to be gradually separated from the fixed structure. .

  With the above configuration, the wiring harness is routed in an inclined manner so as to gradually move away from the fixed structure within the slider, so that the harness portion that is led back from the slider when the slide structure is fully opened is separated from the fixed structure. To do. By disposing the guide rail straight rather than in an inclined shape, the waste of space associated with the inclined arrangement of the guide rail is eliminated.

  According to a fourth aspect of the present invention, there is provided a power feeding apparatus including the harness wiring structure according to any one of the first to third aspects.

  By the said structure, the electric power feeder with which the effect in the harness wiring structure in any one of the said Claims 1-3 is show | played is provided. The power feeding device is mounted on, for example, a slide door of an automobile as a slide structure, and a wire harness is routed from the slide door to a vehicle body as a fixed structure, thereby preventing interference between the wire harness and the vehicle body. As a power feeding device, a guide rail may be arranged in the case to form a unit.

  According to the first aspect of the present invention, the wire harness is inclined outwardly from the slider and is routed away from the fixed structure, so that the wire harness is fixed to the slide structure when the slide structure is fully opened. Interference with the structure is prevented, whereby the wire harness is not worn or damaged, and the reliability of constant power supply from the fixed structure to the slide structure is improved. In addition, since an inexpensive protective tube can be used instead of the conventional expensive caterpillar-shaped exterior member as the exterior member of the wire harness, the harness wiring structure and the power supply device using the same are simplified and reduced in cost. Is done. Moreover, the bending durability of the wire harness is improved by bending the wire harness while bending it with a large radius from the slider. Furthermore, the wire harness is pressed against the slide structure side, whereby the trajectory of the wire harness is stabilized, and the reliability of the constant power supply to the slide structure is further improved.

  According to the invention described in claim 2, the interference between the wire harness and the fixed structure when the slide structure is opened is prevented, and the wire harness and the fixed structure when the slide structure is closed. By preventing this interference, the wire harness is more reliably prevented from being worn or damaged, and the reliability of the constant power supply from the fixed structure to the slide structure is further improved.

  According to the third aspect of the present invention, it is possible to prevent interference between the wire harness and the fixed structure when the slide structure is opened, and to obtain a compact harness routing structure without the inclination of the guide rail. Can do.

  According to invention of Claim 4, the same effect as the harness wiring structure in any one of Claims 1-3 is show | played, for example as an electric power feeder for motor vehicles.

  FIG. 1 shows a basic structure of a harness wiring structure according to the present invention and a power feeding device including the harness wiring structure, and FIG. 2 shows a structure of a slider portion of the power feeding device.

  As shown in FIG. 1, the power feeding device 1 is mounted vertically on a sliding door (sliding structure) of an automobile, and has a rectangular case 2 made of synthetic resin and a lower side inside the case 2. A guide rail 3 provided horizontally and a slider 4 slidably engaged with the guide rail 3 are provided.

  The wire harness 5 includes a plurality of insulation-coated wires 17 and a synthetic resin corrugated tube (protective tube) 18 covering the wires. The slider 4 has a portion (not shown) that is slidably engaged with the guide rail 3 in the case 2 on the wall portion 24 on the back side. The guide rail 3 is plate-shaped and is fixed to the back wall 8 of the case 2 so that the thickness direction coincides with the vehicle width direction, and the engaging portion of the slider 4 is slidably engaged with the groove portion 3a at the center in the height direction. ing.

  In the case 4, the wire harness 5 is bent and arranged from a substantially U shape to a J shape, and the wire harness 5 is folded back by the slider 4 (the folded portion is indicated by reference numeral 14) and held in parallel vertically. The lower harness portion 32 (FIG. 2) protrudes from the horizontally long lower opening 11 of the case 4 and is led out from the slider 4 to the vehicle body (fixed structure) side as a horizontal harness portion 6. The harness portion 6 is smoothly bent with a relatively large radius along the curved harness guide portion 7 at the outlet of the slider 4 (the bent portion is indicated by reference numeral 36).

  The case 2 is formed in a thin shape, and has a front wall 8 and a vertical wall 8 on the back side (left and right) (the front wall is not shown) and upper and side walls 9 and 10. And it can be divided into a base part on the back side and a cover part on the front side. The shape of the case 2 can be appropriately set as necessary. In the specification, front and rear are directions that coincide with the front and rear of the vehicle.

  One end side of the U-shaped harness portion 12 is fixed at the upper front end of the case 2 (the fixing portion is denoted by reference numeral 13), and the other end side of the U-shaped harness portion 12 is the upper half portion 15 of the slider 4 (FIG. 2). ) And is folded back in a U-shape from the top to the bottom outside the front end of the slider 4, and is held and fixed at the lower half 16 of the slider 4, while the vehicle body from the rear opening 22 of the lower half 16. To the side. The upper half portion 15 of the slider 4 is a portion for introducing the wire harness 5 into the case 2, and the lower half portion 16 is a portion for leading the wire harness 5 to the outside, both of which are referred to as a harness holding portion.

  The corrugated tube 18 of the wire harness 5 is a relatively inexpensive existing protective tube in which circumferential concave grooves 19 and ridges 20 (FIG. 2) are alternately arranged in the longitudinal direction of the tube to give good flexibility. . In the example of FIG. 1, a corrugated tube 18 having an oval cross section (flat type) is used, and the corrugated tube 18 in the case 2 is disposed in a horizontally long cross section so as to give a vertical bending property. The corrugated tube 18 on the side is arranged in a vertically long cross section so as to impart flexibility in the front-rear direction.

  As shown in FIG. 2 (longitudinal sectional view), the slider 4 includes a horizontal partition wall 21 in the middle in the height direction, upper and lower rectangular harness holding parts 15 and 16 including the partition wall 21, and a lower harness holding part. A curved harness guide portion 7 (FIG. 1) formed following the side wall near the vehicle body in the rear opening 22 of the portion 16 is provided. In FIG. 2, reference numeral 35 indicates the upper wall of the slider 4, and 28 indicates the lower wall.

  The upper and lower harness holding portions 15 and 16 are divided into upper and lower portions from the intermediate partition wall 21 and are coupled to each other by a locking means (not shown) such as a locking frame piece and a locking projection. The upper harness holding portion 15 has a rear opening 26 in the middle portion in the longitudinal direction of the partition wall 21.

  Each of the upper and lower harness holding portions 15 and 16 is provided with an arc-shaped rib 30 for fixing the harness on the inner surface on the front end side, and each rib 30 is a groove in the corrugated tube 18 of the upper and lower harness portions 31 and 32. By engaging with 19, the upper and lower harness portions 31, 32 are fixed (held) in parallel. By fixing the upper and lower harness portions 31 and 32 back to back, the stress acting on the folded portion 14 and the vicinity thereof is dispersed and the life of the wire harness 5 is increased.

  The U-shaped folded portions 14 protruding from the front ends of the upper and lower corrugated tubes 18 can be covered with a cover portion 33 on the front end side of the slider 4 as indicated by a chain line. The upper harness portion 31 continues to the bent portion 34 in the vertical direction of the wire harness 5 in the case 2, and the lower harness portion 32 is led out toward the vehicle body side.

  In FIG. 1, a case 2 of the power feeding device 1 is fixed to a sliding inner door, for example, a metal inner panel, covered and protected by a synthetic resin door trim (not shown), and horizontally extending from the lower end side of the door trim to the slider 4. The harness portion 6 is routed to the vehicle body side through the transition space (crossover portion) between the door and the vehicle body, and the end portion of the corrugated tube 18 is held by the harness fixing tool on the vehicle body side to fix the harness. It is connected to a wire harness on the vehicle body side (power supply side) through the tool. A harness portion (electric wire) 17 led out from the upper side of the case 2 is connected to each auxiliary machine such as an electrical component in the slide door.

  1 is a state when the left sliding door of the vehicle is opened rearward of the vehicle, and the slider 4 is positioned on the front end side of the guide rail 3 and is led out from the slider 4 to the vehicle body side. The harness portion 6 swings while being pulled forward with the harness fixture on the vehicle body side as a fulcrum.

  When the sliding door is slid forward and closed from the state of FIG. 1, the slider 4 moves to the rear end side of the guide rail 3, and the harness portion 6 toward the vehicle body side is a harness support on the vehicle body side (not shown). Z)) swinging backwards about the fulcrum and extending almost straight. When the sliding door is fully closed, it approaches the vehicle body and comes into close contact. Case 2 also moves integrally along the same path as the sliding door.

  Since the time during which the slide door is closed is absolutely longer than the time during which the slide door is open, the harness portion 6 is stretched almost straight so that the wire harness 5 is not burdened when the slide door is closed.

  FIG. 3 shows a first embodiment of a harness wiring structure according to the present invention and a power feeding device using the same. Since the basic form is the same as in the power supply apparatus of FIG. 1, the same components as those in FIG.

  In FIG. 3 (plan view), reference numeral 44 denotes an automobile slide door (slide structure), 45 denotes a vehicle body (fixed structure), 1 ′ denotes a power supply device mounted on the slide door 44, and 2 denotes a power supply device 1 ′. , 4 is a slider slidably engaged with a guide rail 3 ′ in the case 2, 5 is a wire harness, and 47 is a harness fixture on the vehicle body side.

  The slide door 44 slides rearward along an upper and lower guide mechanism (not shown) and is spaced apart from the vehicle body 45 to be fully opened. The sliding door 44 is brought into close contact with the vehicle body by sliding forward and closing.

  In the embodiment of FIG. 3, the horizontal guide rail 3 ′ in the case 2 is gradually separated from the vehicle body 45 from the front end 3 a to the rear end 3 b in the vehicle width direction (sliding door thickness direction or case thickness). It is characterized by being arranged in a slanted direction.

The heights of the front end 3a and the rear end 3b of the guide rail 3 'are the same or substantially the same. The horizontal distance L ₂ from a vertical panel surface 44a of the slide door 44 to the guide rail rear end 3b is greater than the horizontal distance L ₁ from the panel surface 44a to the guide rail front end 3a. The guide rail 3 'is formed linearly in the front-rear direction.

  Since the guide rail 3 ′ is inclined in the vehicle width direction, the slider 4 engaged with the guide rail 3 ′ is similarly inclined in the vehicle width direction. That is, the slider 4 is inclined in the direction away from the vehicle body 45 from the front end 4a to the rear end 4b, and the slider rear end 4b is located slightly outside the vehicle front end 4a.

  As described above, the rear end 4b of the slider 4, that is, the end on the harness lead-out side, is positioned outwardly along the guide rail 3 'inclined outward, so that the wire harness 5 is shown by the solid line in FIG. As shown, the harness part 5a led out from the slider 4 is inclined to the outside of the vehicle, passes through the substantially U-shaped bent part 36 from the harness part 5a, and the harness support tool in the vicinity of the step part 46 of the vehicle body 45. The harness portion 6 that continues to 47 is routed in a state of being separated from the vehicle body 45 to the outside. A corrugated tube 18 (FIG. 1) made of synthetic resin is attached to the wire harness 5 in the same manner as in the embodiment of FIG.

  When the guide rail 3 is arranged without tilting in the vehicle width direction as in the basic form of FIG. 1, the harness portion 5a led out from the slider 4 faces back as shown by the chain line in FIG. There is a concern that the harness portion 6 that continues to the vehicle body side through the substantially U-shaped bent portion 36 may interfere with the rear end portion 43 of the entrance / exit of the vehicle body 45. By tilting the guide rail 3 ′ in the vehicle width direction in the first embodiment, interference between the wire harness 5 and the vehicle body 45 when the sliding door is fully opened is prevented.

  As the slide door 44 is slid forward from the fully opened state of FIG. 3 and closed, the slider 4 slides along the guide rail 3 ′ toward the rear of the rail, and is more fully open than in the fully opened state of FIG. 3. By further separating from the vehicle body 45 to the outside of the vehicle width, interference between the wire harness 5 and the vehicle body 45 is prevented, the slide door 44 comes close to the vehicle body 45 side immediately before being fully closed, and the wire harness 5 is connected to the vehicle. The body-side harness support 47 is stretched substantially straight while being pulled backward with the fulcrum as a fulcrum. In this manner, the inclined guide rail 3 ′ prevents interference between the wire harness 5 and the vehicle body 45 during the sliding door closing process.

  Further, since the harness portion 5a is led out from the slider 4 as shown by the solid line in FIG. 3, the bending radius of the bent portion (folded portion) 36 increases, and the bending stress applied to the bent portion 36 is increased. The bending durability of the wire harness 5 is improved. Further, the harness portion 5a is always pushed outwardly while being inclined outwardly and is pressed against the slide door 44 side (guide rail 3 ′ side), so that the wire harness 5 is bent and traced between the wire body 5 and the vehicle body 45 (crossover). The swing trajectory at the portion 50) is stabilized, flapping of the wire harness 5 and complicated bending and bending are prevented, thereby preventing interference with the vehicle body 45 and improving the reliability of constant power supply. The stability of the trajectory due to the pressing of the wire harness 5 is promoted by the fact that the guide rail 3 ′ is inclined outward as it goes rearward.

  In the case of the embodiment of FIG. 3, when the size (thickness) of the slider 4 is the same as that of the slider 4 of FIG. 1, the thickness of the case 2 is equal to the guide rail 3 ′ disposed diagonally in the case thickness direction. , A little thicker than case 2 in FIG.

  The shape of the guide rail 3 ′ is not limited to a straight line, and may be a substantially wave shape or a substantially crank shape (not shown) with front and rear straight portions and an intermediate inclined portion, for example. The rear straight portion is positioned on the outer side in the vehicle width direction than the front straight portion. A connecting portion between the inclined portion and the straight portion is smoothly formed in a curved shape, and the slider 4 can smoothly advance and retract. When the slider 4 is positioned at the middle inclined portion, the rear end 4b of the slider 4 is swung outward in the vehicle width direction, and the wire harness 5 is routed in the same form as the solid line in FIG.

  Further, instead of arranging the guide rail 3 ′ in an inclined manner in the case 2 of the power feeding device 1 ′, the power feeding device 1 in the form of FIG. 1 (the guide rail 3 is arranged in parallel with the vertical inner and outer walls of the case 2. It is also possible to dispose the case 2 on the slide door 44 so as to be inclined outward in the vehicle width direction (the rear end 2b of the case 2 is positioned on the outer side in the vehicle width direction with respect to the front end 2a). However, in this case, it is necessary to form an inclined attachment portion on the slide door itself.

  4 to 5 show a second embodiment of a harness routing structure according to the present invention and a power feeding apparatus including the harness routing structure. Since the basic form is the same as in the power supply apparatus of FIG. 1, the same components as those in FIG.

  In FIG. 4 (plan view), reference numeral 44 denotes an automobile slide door (slide structure), 45 denotes a vehicle body (fixed structure), 1 ″ denotes a power supply device mounted on the slide door 44, and 2 denotes a case of the power supply device. 4 'is a slider slidably engaged with the guide rail 3 in the case, 5 is a wire harness, and 47 is a harness fixture on the vehicle body side.

  In the present embodiment, the guide rail 3 is disposed horizontally in the case 2 of the power feeding device 1 ″ and in parallel with the inner and outer walls 8 and 8 ′ of the case 2 and the slide door 44 and is slidably engaged with the guide rail 3. In the slider 4 ′ made of synthetic resin, the wire harness 5 is arranged in an inclined manner so as to be gradually separated outward in the vehicle width direction from the front to the rear.

The horizontal distance L ₃ to the front end 3a of the guide rail 3 from the panel surface 44a of the slide door 44 is the same as the horizontal distance L ₃ to the rear end 3b of the guide rail 3, the front end 3a of the guide rail 3 from the vehicle body 45 The horizontal distance to the rear end 3b is the same.

  As shown in FIG. 5, the wire harness 5 is routed while being inclined in the slider thickness direction in the lower half portion 16 ′ of the slider 4 ′ (the harness inclined portion is indicated by reference numeral 32 ′). As shown, it is routed on the vehicle body side while being smoothly bent with a relatively large radius from the inclined portion 32 'through the curved harness guide portion 7 on the rear opening 22 side.

  An inclined harness insertion hole 26 and a straight harness insertion hole 27 on the front end side are formed on the inner side of the slider 4 ′. The inclined harness insertion hole 26 continues to the rear opening 22, and the rear opening 22 extends vertically. It is covered with the wall part 28 and the outer wall part 24, and the harness guide part 7 is located inside. A harness holding (fixing) rib 30 projects from the harness insertion hole 27 on the front end side, and the concave groove 19 of the corrugated tube 18 (FIG. 2) of the wire harness 5 is engaged with the rib 30.

  The slider 4 'can be divided vertically, and the wire harness 5 is inserted into the harness insertion holes 26 and 27 in the divided state, and the upper and lower divided sliders are locked and fixed to each other by locking means. When the sliding door 44 is fully closed, the harness portion 6 of the wire harness 5 is extended rearward substantially straight and without slack, as shown by a chain line in FIG. In the upper half portion 15 of the slider 4 ′, the upper harness portion 31 is arranged in parallel with the lower harness portion 32 as shown in FIG. 2. The upper harness portion 31 does not need to be inclined in the vehicle width direction, and is linearly routed in the front-rear direction and continues to the harness portion in the case 2. A corrugated tube 18 made of synthetic resin is attached to the wire harness 5 as in the embodiment of FIG.

  In this manner, the wire harness 5 is tilted while being swayed outward in the vehicle width direction in the slider 4 ′ and routed rearward (the harness inclined portion is indicated by reference numeral 32 ′), and as indicated by the solid line in FIG. Furthermore, the harness portion 5a led out from the slider 4 'is inclined and positioned outside the vehicle, and the harness portion 6 that continues from the harness portion 5a through the substantially U-shaped bent portion 36 to the harness support 47 of the vehicle body 45 is provided. It is routed in a state of being separated from the vehicle body 45 to the outside.

  When the guide rail 3 is arranged without inclination in the vehicle width direction as in the basic form of FIG. 1, as shown by the chain line in FIG. 4, the harness portion 5a led out from the slider 4 faces back and the harness portion 5a There is a concern that the harness portion 6 that continues to the vehicle body side through the substantially U-shaped bent portion 36 may interfere with the rear end portion 43 of the entrance / exit of the vehicle body 45. By arranging the harness 5 to be inclined outward in the vehicle width direction, interference between the wire harness 5 and the vehicle body 45 when the sliding door is fully opened is prevented.

  As the slide door 44 is slid forward and closed from the fully opened state of FIG. 4, the slider 4 ′ slides along the guide rail 3 toward the rear side of the rail, and the slide door 44 immediately before fully closed. Thus, in the vicinity of the vehicle body side, the wire harness 5 is stretched substantially straight while being pulled rearward with the harness support 47 on the vehicle body side as a fulcrum. Since the wire harness 5 is maintained without being bent for a long time when the slide door is fully closed, the durability (life) of the wire harness 5 is improved.

  Also, as shown in the solid line in FIG. 4, the harness portion 5 a is led out from the slider 4 so as to be inclined outward, whereby the bending radius of the bent portion (folded portion) 36 increases, and the bending stress applied to the bent portion 36 is increased. The bending durability of the wire harness 5 is improved. Further, the harness portion 5a is always pressed outward while being inclined outwardly and is pressed against the slide door 44 side (guide rail 3 side). 50), the swing trajectory of the wire harness 5 is stabilized, and the wire harness 5 is prevented from flapping and complicated bending and bending. This also prevents interference with the vehicle body 45 and improves the reliability of constant power supply.

  In each of the above embodiments, the wire harness 5 is routed in a substantially U shape within the case 2, but the wire harness 5 is looped, chevron-shaped, or swingable (pendulum-shaped) within the case. It is also possible to route. In this case, the case 2 may be a square instead of a rectangle.

  In the above embodiment, the wire harness 5 is expanded and contracted in the case using the case 2, but the guide rails 3 and 3 ′ are directly attached to the panel surface 44 a of the slide door 44 without using the case 2. It is also possible to arrange.

  Moreover, in each said embodiment, although the corrugated tube 18 was used as a harness exterior member (protective tube), a net-like tube, another resin tube, an elastic tube, etc. other than that were used, or without using a protective tube. It is also possible to use a plurality of electric wires 17 in a state of being partially bundled with a tape, a band or the like. The protective tubes other than the corrugated tube 18 can be fixed to the sliders 4 and 4 'through, for example, sharp protrusions, welds, or other adapters, without depending on the ribs 30 in FIG. .
