Description

  The present invention relates to a power supply device that is mounted on a slide door of an automobile, for example, and constantly supplies power from the vehicle body side to the slide door side.

  FIG. 10 shows an embodiment of a conventional power supply device for a sliding door (see Patent Document 1).

  This power supply device 50 is disposed on a slide door 41 of an automobile, and has a substantially reverse fan-shaped synthetic resin protector 42 that houses a wire harness 43 bent in an arc shape, and a horizontal protector 42 provided in a lower portion of the protector. A metal guide rail 44, a slider 46 slidably engaged with the guide rail 44, and vertical and horizontal swing arms 49 provided on the slider 46 are provided.

  The protector 42 includes a protector base (substitute with reference numeral 42) and a protector cover 54. The protector base and the protector cover 54 each have a vertical base wall 51 and an outer peripheral peripheral wall 52 that are opposed to each other. The protector base is locked by the stopping means, and the protector base is fixed to the panel of the slide door 41 with a bolt or the like.

  An opening 55 for leading out the harness is provided at the front upper end of the protector base, a harness fixing plate 56 is provided at the opening edge, and a horizontally long opening 45 for leading out the harness is provided at the lower end of the protector cover 54.

JP 2001-354085 A (FIG. 1)

  However, the above-described conventional power supply apparatus includes a guide rail 44 for moving the wire harness 43 in the vehicle front-rear direction together with the slider 46 and an arm 49 for swinging the wire harness 43. However, there is a problem in that the power supply structure is enlarged in the thickness direction of the door by the amount of protrusion of the arm 49.

  In view of this, the present applicant has previously proposed a structure in which the slider is spherical, the wire harness is inserted and held in the slider, and the groove-shaped guide portion having an arcuate cross section is formed integrally with the protector (Japanese Patent Application No. 2006-17639). ). With this structure, the area around the slider has been made compact, but in order for the slider to rotate freely, for example, when the wire harness is twisted one turn when the vehicle is assembled, the harness fixing tool for the wire harness is assembled on the vehicle body side. Therefore, there is a concern that the wire harness may be twisted, and in order to prevent this, it is necessary to take time for assembly management.

  This concern may also occur when each of the power feeding devices is applied to a slide structure such as a slide door of a vehicle other than an automobile, a slide door of a machine tool, or the like instead of the automobile slide door.

  In view of the above points, the present invention provides a power feeding device that can easily and reliably prevent erroneous assembly in a state where a wire harness is twisted, and that can improve the reliability of constant power feeding. Objective.

  In order to achieve the above object, a power supply device according to claim 1 of the present invention is provided with a guide portion having an arcuate cross section in a protector that allows a wire harness to be swingably led out, and a slider is slidable on the guide portion. The slider includes an inner member that fixes the wire harness, and an outer member that has an arcuate cross section that rotatably holds the inner member. The inner member and the outer member A first rotation restricting means is provided, and the outer member is provided with a second rotation restricting means for the protector.

  With the above configuration, when the wire harness is twisted, the rotation angle between the inner member and the outer member of the slider is defined within a required range (the rotation range when the wire harness swings) by the first rotation restricting means. The rotation angle and the swing angle of the outer member with respect to the protector are regulated to be extremely small by the second rotation restricting means. The inner member rotates and swings integrally with the wire harness. The rotation is the movement in the circumferential direction of the wire harness, and the swing is the movement in the swinging direction of the wire harness. The inner member rotates the wire harness in the circumferential direction at a required angle, and the outer member only performs a sliding operation along the longitudinal direction of the guide portion.

  The power supply device according to claim 2 is the power supply device according to claim 1, wherein the first rotation restricting means has a protrusion of the inner member and a rib in the harness insertion direction of the outer member that makes the protrusion contact. It is characterized by being.

  With the above configuration, when the inner member rotates in the circumferential direction of the wire harness, the protrusion of the inner member abuts against the rib of the outer member and further rotation is prevented. The rotation range is a required rotation range when the wire harness is swung.

  A power supply device according to a third aspect is the power supply device according to the first or second aspect, wherein the second rotation restricting means is a protrusion that abuts against an inner surface of the guide portion.

  With the above configuration, the protrusion of the outer member abuts against the inner surface of the guide portion of the protector, and the rotation of the outer member is restricted to a small extent. If the protrusions are provided symmetrically with each other and the protrusions are brought into contact with the inner surfaces of the guide portions of the opposing wall portions of the protector (the wall portions of the protector base and the protector cover), the rotation angle is regulated to be extremely small. The

  According to a fourth aspect of the present invention, in the power feeding device according to the first or second aspect, the second rotation restricting means is a wall portion that protrudes from the outer member and contacts the inner surface of the protector. And

  With the above configuration, the wall portion projecting from the outer member having an arcuate cross section abuts against the inner wall surface of the protector, thereby preventing the outer member from rotating in the harness circumferential direction, and rotating the inner member in the outer member. Is regulated to the required angle by the first rotation regulating means. The wall portion is preferably flat. For example, if a rectangular cylindrical wall portion is used, the wall portion has high rigidity, and rotation regulation by contact is reliably performed.

  A power feeding device according to a fifth aspect is the power feeding device according to any one of the first to fourth aspects, wherein the guide portion is provided with a slit, and the outer member is provided with a protrusion slidably engaged with the slit. It is characterized by that.

  With the configuration described above, the protrusion of the outer member is engaged with the slit of the guide portion of the protector, thereby preventing the outer member from rotating in the circumferential direction. Further, there is no fear that the outer member, that is, the slider is detached from the guide portion. According to the fourth aspect of the present invention, when the protrusion is provided on the outer member provided with the protruding wall portion, the synergistic action of the wall portion and the protrusion can further prevent the rotation.

  According to the first aspect of the present invention, since the rotation of the wire harness in the torsional direction is performed within a predetermined range only by the inner member, and the outer member is responsible only for the sliding operation along the guide portion, the protector is assembled to the slide structure side. When the wire harness is fixed to the fixed structure side, twisting of the wire harness is suppressed to a necessary minimum, thereby reliably preventing the wire harness from being fixed to the fixed structure side in a twisted state. As a result, the worry about breakage of the wire harness is eliminated, and the reliability of constant power supply is improved.

  According to the second aspect of the present invention, the slider can be formed with a simple structure at a low cost by integrally molding the protrusion and the rib on the inner member and the outer member.

  According to the third aspect of the present invention, the twist of the wire harness can be reliably controlled at low cost with a simple structure in which the protrusion is brought into contact with the inner surface of the protector.

  According to the invention described in claim 4, since the wall portion protruding from the outer member can be reliably brought into contact with the inner surface of the protector with a large area, the rotation of the outer member can be reliably controlled. The effect described in item 1 is reliably exhibited.

  According to the invention described in claim 5, the protrusion of the outer member is engaged with the slit of the guide portion, so that the rotation of the outer member is more reliably prevented by the synergistic action with the second rotation restricting means, The effect of Claim 1 is exhibited reliably. In addition, the slider is securely engaged with the guide portion without coming off, and the reliability of constant power supply is improved.

  The protector 2 includes vertical wall portions 7 and 8 on the left and right sides (front side and rear side) in the vehicle width direction, peripheral wall portions 9 to 11 that connect the wall portions 7 and 8 at the front and rear sides, and the upper side, and a lower harness lead-out. And the front wall portion 7 is formed shorter at the lower end side than the rear wall portion 8, the opening 12 is located at the lower end of the front wall portion 7, The lower end of each of the wall portions 7 and 8 on the back side is inclined in the latter half.

  The guide portion 4 having a pair of guide grooves 4 ′ is linearly formed by integral resin molding so as to oppose the front and rear wall portions 7, 8, and bulges outward to guide portion 4. The outer wall (groove wall) 21 having an arcuate vertical cross section protrudes outward from the outer surfaces of the wall portions 7 and 8 on the front side and the back side.

  In the center of the guide portion 4 in the width direction, a slit 20 is provided through the groove wall 21 from the front end to the rear end of the guide groove 4 ′. The slit 20 may be provided in any one of the guide portions 4 (in this example, the guide portion 4 of the front wall 7) (in this case, there will be one protrusion of a slider in FIG. 8 described later), and both guide portions 4 are provided. You may provide in (each guide part of the front wall 7 and the back wall 8).

  The front wall 7 of the protector 2 is resin-molded separately from the protector base, which is the back wall 8 as a protector cover, and is joined to each other by locking means and fixing means via the peripheral walls 9-11. Is done. The opening edge 7a of the wall 7 on the front side is curved outward, and the wire harness 3 is bent without difficulty along the opening edge 7a toward the vehicle body.

  The wire harness 3 is introduced obliquely rearward and downward from the hole 14 of the upper wall, which is the horizontal peripheral wall portion 11 on the upper side of the protector 2, and is folded obliquely forward and upward between the upper wall 11 and the middle of the protector 2 in the height direction. As a result, the curved portion 5 continues to the guide portion 4 and is routed downward from the guide portion 4 through the opening 12 to the vehicle body side. The diagonally downward harness portion 15 and the folded harness portion 5b are arranged along a substantially J-shaped inclined guide wall 16 and are fixed to the guide wall 16 and the rear side by a fixing means (fixing portion) 17 such as a band. It is fixed to the wall 8. The diagonally downward harness portion 15 follows a harness portion (not shown) led out to the outside of the protector 2, and the led harness portion is connected to an auxiliary device such as an electrical component on the slide door side.

  The upper half of the protector 2 is formed thinner than the lower half, the guide part 4 is provided in the lower half, and a substantially spherical slider 6 is slidably engaged with a pair of opposed guide grooves 4 ′. A wire harness 3 is routed through 6. An inner member 23 of the slider 6 is fixed to the outer periphery of the wire harness 3.

  The outer member 24 of the slider 6 is slidable in the longitudinal direction of the guide portion 4 as shown by an arrow B in FIG. 1, and the inner member 23 of the slider 6 is guided around the axis of the wire harness 3 as shown by an arrow C. It can rotate within a certain range, and can swing (swing) within a certain range as indicated by an arrow D together with the harness portion 18 on the vehicle body side from the slider 6.

  2 is an exploded perspective view of the slider 6, FIG. 3 is an exploded front view of the slider 6, and FIGS. 4A and 4B are a side view and a front view of the slider 6, respectively.

  As shown in FIGS. 2 and 3, the inner member 23 of the slider 6 is formed in a substantially spherical shape and has an outer peripheral surface 31 having a circular arc cross section, and the front and rear ends in the harness insertion direction are cut out in a plane in the harness orthogonal direction (notch). A short cylindrical protrusion 26 (first rotation restricting means) for stopping is provided at two positions 180 degrees (symmetric) at the center position in the harness insertion direction on the outer peripheral surface.

  The inner member 23 is formed so that it can be divided into two parts (the dividing surface is indicated by reference numeral 27 in FIG. 3), and the locking claw 29 of one divided inner 23a, which is the locking means (FIG. 3), and the other split inner 23b are possible. They are fixed to each other with a flexible locking frame 28. The locking means is not limited to this.

  A harness insertion hole 30 is opened in the notch surfaces 25 at both ends of the inner member 23, and the corrugated tube 18, which is a protective tube of the wire harness 3, is fixed in one opening of the hole 30, and from the other opening of the hole 30. The electric wire part 5 (FIG. 1) of the wire harness 3 is derived. It is preferable that the electric wire part 5 is covered with a flexible reticulated tube or the like to prevent scattering. An annular rib (not shown) is provided in one opening of the hole 30, and a circumferential concave groove 18a (FIG. 3) of the corrugated tube 18 is engaged and fixed to the rib. The corrugated tube 18 may be oval in cross section (flat type) or circular. In the case of a corrugated tube having an oval cross section, the harness insertion hole 30 of the inner member 23 is also formed in an oval cross section.

  The outer member 24 of the slider 6 can be divided into two parts, and each of the divided outer parts 24 a and 24 b has an outer peripheral surface 32 and an inner peripheral surface 33 having a circular arc cross section, and the inner peripheral surface 33 is substantially the same as the outer peripheral surface 31 of the inner member 23. The inner member 23 is supported with the same radius of curvature so that it can be smoothly rotated and swung. The length of the outer member 24 in the harness insertion direction is slightly shorter than the length of the inner member 23, and both end portions of the inner member 23 protrude from the outer member 24 in the harness insertion direction in the assembled state of FIG. 4.

  Circumferential ribs 35 (first rotation restricting means) project from the inner edges of the openings 34 at both ends of each divided outer 24a, 24b, and the center position of the inner peripheral surface 33 of each divided outer 24a, 24b. Thus, ribs 36 (first rotation restricting means) project in the axial direction (harness insertion direction), and the axial ribs 36 are orthogonal to the circumferential ribs 35 and continue integrally. There are no obstacles such as ribs at the dividing positions (dividing surfaces) 37 (FIG. 3) of the outer members 24a, 24b, and the protrusions 26 on the outer periphery of the inner member 23 pass through the dividing position 37 in the circumferential direction. It can move smoothly from the outer 24a to the other divided outer 24b.

  When the protrusion 26 of the inner member 23 abuts on the circumferential rib 35, the swing angle of the inner member 23 (wire harness 3) is defined, and the protrusion 26 of the inner member 23 abuts on the axial rib 36. Thus, the rotation angle, that is, the twist angle of the inner member 23 (wire harness 3) is defined.

  The position of the axial ribs 36 is not limited to the center, and the number and thickness of the axial ribs 36 are not limited to the example of FIG. It is set accordingly. The same applies to the circumferential ribs 35.

  Both split outers 24a, 24b are fixed to each other by locking means outside the split surfaces 37 on both sides. As a locking means, a flexible locking frame 38 is provided on one side of one split outer 24a, a locking projection 39 and a substantially U-shaped protruding wall 40 on the outside thereof are provided on the other side, A locking projection 39 that engages with the locking frame 38 of one split outer 24a and a substantially U-shaped protruding wall 40 on the outside thereof are provided on one side of the split outer 24b. A locking frame 38 that engages with the locking projection 39 of the split outer 24a is provided. Each substantially U-shaped protruding wall 40 engages with the outside of each locking frame 38. The projecting wall 40 is composed of a pair of projecting pieces 40a and a connecting portion 40b orthogonal to each other. A hole 38 a is provided inside the locking frame 38.

  The locking frame 38 and the protruding wall 40 protrude radially outward from the outer peripheral surface 32 of each divided outer 24a, 24b. As shown in FIG. 4, the locking projection 39 engages with the hole 38 a of the locking frame 38, the protruding wall 40 joins to the outer peripheral surface of the locking frame 38, and one large block (two on both sides). A shaped protrusion (second rotation restricting means) 60 is formed.

  The protrusion 60 acts as a contact portion with respect to the protector 2 (FIG. 1), prevents the outer member 24 from rotating and swinging, and the longitudinal direction of the guide portion 4 (FIG. 1) of the protector 2 on the outer member 24. Only the sliding movement to is allowed. It is preferable that the outer surface 60 a of the protrusion 60 has a curved shape along the outer surface 32 of the outer member 24.

  5A and 5B show that when the outer member 24 of the slider 6 is about to rotate in the guide portion 4 of the protector 2, each protrusion 60 of the outer member 24 is formed in the guide groove 4 ′ of each guide portion 4. It shows a state in which the rotation and the swing are restricted by contacting the inner surface or the like. The slider 6 is located on the front end side of the guide portion 4 when the slide door of FIG. 1 is fully opened.

5A, one protrusion 60 ₁ of the outer member 24 of the slider 6 abuts on the curved inner surface of the guide part 4 of the protector base 8, and the other protrusion 60 ₂ is the protector cover 7 (FIG. 1). The guide portion 4 is in contact with the curved inner surface. From this state, the outer member 24 slightly rotates in the circumferential direction, and as shown in FIG. 5B, one protrusion 60 ₁ comes into contact with the inner surface of the guide part 4 of the protector cover 7 and the other protrusion 60 ₂ Further contact with the inner surface of the guide portion 4 of the protector base 8 prevents further rotation of the outer member 24.

5A, the lower end surface 60a of _one protrusion 60 _{1 is in contact with} the lower end 4c of the guide portion 4 of the protector base 8, and the upper end surface 60b of the other protrusion 60 ₂ is the guide of the protector cover 7. By abutting the upper end 4d of the portion 4, the swinging of the outer member 24 in one direction is prevented, and when the head is slightly swung in the other direction as shown in FIG. 60 ₁ of the upper end 60b abuts against the upper end 4b of the guide portion 4 of the protector cover 7, that the other projection 60 ₂ of the lower end 60a abuts against the lower end 4c of the guide portion 4 of the protector base 8, the outer member 24 Further swinging is prevented. Even if the protrusions 60 are not a pair but one, the same effect can be obtained.

  6 to 9 show another embodiment (more precisely, two embodiments) of the power feeding device according to the present invention. Since the configuration other than the slider 61 is the same as that in FIG. 1, the same components as those in FIG.

  As shown in FIG. 6, the power feeding device 1 ′ has a vertical cross-sectional arc shape on a rectangular protector 2 made of synthetic resin that is arranged vertically (vertically placed) on a door inner panel of a sliding door and fixed with bolts or the like. A guide portion 4 having a pair of opposed guide grooves (groove portions) 4 ′ is integrally molded with resin, and a slider 61 comprising a substantially spherical inner member 23 and an outer member 24 ′ made of synthetic resin is formed in the pair of guide grooves 4 ′. In which the wire harness 3 is fixed to the inner member 23 of the slider 61, and the outer member 24 ′ having a circular arc cross section has a rectangular box shape. A wall portion (second rotation restricting means) 62 is integrally provided, and the box-shaped wall portion 62 is brought into contact with the inner wall surface of the protector 2 to restrict the rotation and swing of the outer member 24 '. is there.

  FIGS. 7A and 7B show a front view and a side view of the slider 61. A rectangular box-shaped wall portion 62 is formed to protrude from the upper end of the substantially spherical outer member 24 ′, and FIG. As shown in FIG. 7B, the width of the long side 63 of the box-shaped wall 62 is approximately the same as the outer diameter of the outer member 24 ', and the width of the short side 64 of the box-shaped wall 62 is the outer member. It is smaller than the outer diameter of 24 'and slightly smaller than the thickness of the space in the protector 2 of FIG.

  As shown in FIG. 9, the box-shaped wall portion 62 is provided with a horizontally-long rectangular hole 65 for inserting a harness, and the hole 65 follows the hole for inserting the harness of the inner member 23. The corrugated tube portion of the wire harness 3 is fixed in the portion, and the electric wire portion 5 of the wire harness 3 can swing along the protector 2 in the hole 65 of the box-shaped wall portion 62.

  As shown in FIG. 7, the outer member 24 ′ and the box-shaped wall portion 62 can be integrally divided into two parts. The divided members include a locking frame piece 66, a locking projection 67, and a locking frame 69 in the through hole 68. They are fixed to each other by locking means such as locking protrusions. The type of the locking means can be set as appropriate. The locking means 66 and 67 of the outer member 24 'are not large but small as in the previous example (FIG. 4). The structure of the inner member 23 is the same as that of the previous example. The inner surface 23 has a protrusion 26 (FIG. 2) on the outer peripheral surface 31 (FIG. 2), and the protrusion 26 is a rib 35, 36 on the inner peripheral surface of the outer member 24 ′ (FIG. 2). Can be contacted. Since other configurations are the same as those of the previous example, description thereof is omitted.

  The slider 61 ′ in FIG. 8 has a pair of left and right protrusions 71 symmetrically provided on the outer peripheral surface 32 of the outer member 24 ′ of the slider 61 in FIG. 7, and protrudes into the slit 20 provided in the guide portion 4 of the protector 2 as shown in FIG. The difference is that 71 is slidably engaged. Other configurations are the same. The protrusion 71 is formed to project in the outer diameter direction of the outer member 24 ′ perpendicular to the harness insertion direction. The protrusion 71 is short cylindrical or hemispherical.

The box-shaped wall 62 of the slider 61 ′ abuts against the inner wall surface 72 of the protector 2 as shown in FIG. The rotation in the direction (arrow C direction in FIG. 6) is prevented. One wide surface 63 ₁ of the box-shaped wall 62 abuts on the inner wall surface 72 of the protector base 8, and the other surface 63 _{2 of} the box-shaped wall 62 is the inner wall surface of the protector cover 7 (see FIG. 6). 62 abuts.

  Further, the circumferential rotation of the outer member 24 ′ is also prevented by the protrusion 71 of the outer member 24 ′ engaging with the slit 20 of the guide portion 4 of the protector 2. Due to the engagement between the protrusion 71 and the slit 20, the swinging of the outer member 24 'is suppressed. In addition, due to the engagement between the protrusion 71 and the slit 20, the concern that the outer member 24 ′ is pulled out from the guide portion 4 (guide groove 4 ′) is eliminated.

  It is also effective to provide the outer member protrusion 72 of FIG. 8 on the outer peripheral surface 32 of the outer member 24 of FIG. In this case, in FIG. 1, the protrusion 32 of the outer member 24 is slidably and rotatably engaged with the slit 20 of the guide portion 4, so that the rotation of the outer member 24 is restricted and the swinging is also restricted to some extent. The

  Below, operation | movement of the wire harness 3 at the time of opening and closing of a sliding door is demonstrated.

  As shown in FIGS. 1 and 6, when the sliding door is fully opened (in the protector 2 on the left side in the drawing), the wire harness 3 is extended back and forth while curving upward in a low mountain shape with a large radius. The height (for example, the vertical distance from the slider 6 to the curved top 5c) can be kept low. The slider 6 is located at the front end 4a of the guide groove 4 '. The length of the imaginary straight line connecting the slider 6 and the fixed portion 17 is several times longer than the height from the imaginary straight line to the curved top 5c, and the curved portion 5 close to a flat shape is formed. The protector 2 is made compact (low profile) in the height direction by arranging the curved portion 5 of the wire harness 3 in a flat shape in the protector.

  The harness portion 18 in front of the slider 6 is positioned slightly downward from the horizontal at the transition portion while being pulled forward with the harness support 19 as a fulcrum. When the slide door is fully opened, the protector 2 is separated from the vehicle body together with the slide door, and the harness portion 18 at the transition portion is drawn obliquely forward in plan view from the protector 2 to the harness fixture 19.

  When the sliding door is fully closed (in the protector 2 on the right side in the figure), the wire harness 3 is bent (bent) in a shape close to a loop shape with a small radius and is pulled rearward over the harness fixture 19 to be positioned horizontally. To do. The top portion 5c of the substantially loop-shaped (substantially horizontal U-shaped) curved portion 5 rotates upward with the lower fixing portion 17 as a fulcrum and is positioned higher than when the sliding door is fully closed (the left protector in the figure). To do. The slider 6 is positioned at the rear end 4b of the guide groove 4 ′, and the height of the slider 6 and the harness fixture 19 is substantially equal, and the harness portion 18 from the slider 6 to the harness support 19 does not sag and is the shortest distance horizontally. To position.

  Since the harness portion 18 does not hang down, the harness portion 18 is reliably prevented from being caught between the sliding door and the vehicle body, and the harness portion 18 is positioned at the shortest distance so that the harness portion 18 is shortened and reduced. Cost is increased. Within the protector, the wire harness 3 is accommodated in a substantially loop shape and is absorbed by the extra length.

  The length of the curved portion 5 in the protector (the length of the harness from the fixed portion 17 to the slider 6) does not change between when the slide door is fully closed and when it is fully open. Similarly, the length of the harness portion 18 from the slider 6 to the harness support 19 does not change.

  When the slider 6 moves along the guide groove 4 ′, the wire harness 3 is pulled out from the lower part of the front end of the protector 2 to the harness support 19 in the vicinity of the front end 4a of the guide groove 4 ′ when the slide door is fully opened. When the door is fully closed, the wire harness 3 is drawn horizontally from the rear end 4b of the guide groove 4 'horizontally through the protector 2 to the harness support 19 from the rear end of the protector 2.

  The bending portion 5 of the wire harness 3 in the protector changes smoothly from a low mountain shape to a substantially loop shape as the slider 6 moves, so that the sliding door can be opened and closed with the harness support 19 as the center. Can be supported.

  When the sliding door is fully closed (in the right protector 2 in the figure), the bending center point of the substantially loop-shaped curved portion (bending portion) 5 of the wire harness 3 is located in the vicinity of the upper side of the slider 6 in the protector. The fixing portion 17 of the wire harness 5 is located in the upper half of the protector 2, and the horizontal harness portion 18 toward the slider 6 and the harness fixture 19 is located in the lower half of the protector 2.

  A gap 24 about the radius of the substantially loop-shaped curved portion 5 is vacated between the fixed portion 17 and the horizontal harness portion 18. The wire harness 3 in the protector is extended in the door opening / closing direction (front-rear direction) when the sliding door is fully closed, and is shortened in the door opening / closing direction when the sliding door is fully opened. As the sliding door is opened and closed, the wire harness 3 expands and contracts in the door opening and closing direction in the protector.

  The length of the harness portion 18 led out from the right protector 2 to the harness fixture 19 when the sliding door is fully closed is shorter than the length of the left harness portion 18 when the sliding door is fully opened. Is derived from the protector 2 in a substantially straight rearward direction.

  In the half-open state of the sliding door, the slider 6 is positioned approximately in the center in the longitudinal direction of the guide groove 4 ′, and the slider 6 and the harness support 19 are positioned so as to face each other in the left and right direction (vehicle width direction). The bending portion 5 of the harness 3 has a substantially intermediate diameter between the bending radius of the bending portion 5 when the left sliding door is fully opened and the bending radius of the bending portion 5 when the right sliding door is fully closed.

  In each of the above embodiments, the inner member 23 and the outer member 24 of the slider 6 are both formed in a substantially spherical shape. For example, the inner member 23 is formed in a cylindrical shape, and the outer member 24 is formed in a substantially spherical shape. It is also possible to provide a projection (for example, reference numeral 26 in FIG. 2) on a cylindrical inner member (not shown), and to provide ribs 35 and 36 for abutting the projection 26 on the inner peripheral surface of the outer member 24.

  Further, in the embodiment of FIG. 1, as the first rotation restricting means, the inner member 23 is provided with the protrusion 26, and the outer member 24 is provided with the ribs 35 and 36 in the XY directions (circumferential direction and axial direction). However, for example, the protrusion (26) can be provided on the outer member (24), and the ribs (35, 36) can be provided on the inner member (23). Further, the configuration of the first rotation restricting means can be appropriately set as necessary.

  Further, in the embodiment of FIG. 1 described above, the outer member 24 is provided with the block-shaped protrusion 60 as the second rotation restricting means, but instead of the block-shaped protrusion 60, a pin (not shown) is provided. Or a part of the outer peripheral surface 32 of the outer member 24 can be changed from an arc shape to a flat shape to form a contact wall (not shown).

  Further, in the embodiment of FIG. 6 described above, the outer member 24 ′ is provided with the rectangular box-shaped wall 62 as the second rotation restricting means, but instead of the rectangular box-shaped wall 62, a triangular shape or the like is provided. A box-shaped wall (not shown) is provided, two plate-like walls (not shown) are provided opposite to each other, not in a box shape, or facing upward (outer harness insertion direction) from the outer member 24 '. Two or four pins (not shown) can be provided in a protruding manner.

  Moreover, although the said electric power feeder was applied to the sliding door of the motor vehicle in the said embodiment, the said electric power feeder is applicable also to the sliding door in the sliding door of other vehicles other than a motor vehicle, other manufacturing apparatuses, etc. These sliding doors are collectively referred to as a sliding structure, and the vehicle body and the apparatus main body are collectively referred to as a fixed structure.
