A first harness outlet 60 is formed by at least one end (front end) of the restriction wall 57 and the upper wall portion 58a of the base wall 58. A horizontally long second harness outlet 61 is formed between the other end (rear end) of the restriction wall 57 and the side wall 58b or the lower wall 58c of the base wall 58.

  The restriction wall 57 is formed so as to restrict the position of the bending portion 53 of the wire harness 3 urged by the elastic member 52. In this embodiment, it is formed in an arc shape that faces upward. On the second harness outlet 61 side of the restriction wall 57, an extension portion 62 that extends straight behind the slide door 1 is coupled. Mounting flanges 63 and 64 for the inner panel 8 are formed on the outer edge of the restriction wall 57 and the outer edge of the extension 62. The protector body 54 is fastened and fixed by bolts 65 and 65 via mounting flanges 63 and 64. It should be noted that the locking member 34 (see FIG. 2) may be provided on the mounting flange 64.

  The base wall 58 forms a first harness outlet 60 and a second harness outlet 61, and a bolt 65 is fastened to a mounting flange 66 provided on the base wall 58 in the same manner as the mounting flanges 63 and 64. It is like that.

  The fixed wall 59 is disposed in parallel to the restriction wall 57 in the vicinity of the first harness outlet 60, and is formed so that the corrugated tube 19 can be inserted and fixed. That is, on the fixed wall 59, for example, two locking projections 67 and 67 which are fitted into the groove of the corrugated tube 19 are formed. Two locking projections 67, 67 are also formed on the opposing regulating wall 57 (the number of locking projections 67 is an example).

  As shown in FIG. 4, the cover 55 includes a cover-side substrate portion 68 that faces the substrate portion 56, a curved peripheral wall 69 that extends along the restriction wall 57, and a short side wall 70 that extends along the base wall 58. . One end side of the peripheral wall 69 and the side wall 70 contributes to the formation of the first harness outlet 60 (see FIG. 5), and the other end side contributes to the formation of the second harness outlet 61 (see FIG. 5). On the other end side edge portion, a flange portion 71 protruding outward is formed. The collar portion 71 has a curved surface (not shown) with which the door-side wire harness 3 led out from the second harness outlet 61 contacts via the corrugated tube 19. Since the curved flange 71 does not come into sliding contact with the door-side wire harness 3 at the edge when the sliding door 1 is opened and closed, the movement of the derived door-side wire harness 3 (including the corrugated tube 19) is made smooth. In addition, the door-side wire harness 3 (including the corrugated tube 19) is prevented from being damaged and the durability is improved. Further, the door-side wire harness 3 is bent downward along the curved flange 71 and led out to the vehicle body 2 side so as not to interfere with the lower end of the door trim (not shown) of the slide door 1. Rubbing with the lower end of the is prevented.

  The cover 55 is assumed to be engaged with the protector main body 54 from the vehicle body 2 side using appropriate means. For example, a locking portion (not shown) is provided on the outer peripheral surface of the restriction wall 57 of the protector body, and an engaging portion (not shown) for the locking portion is provided on the peripheral wall 69 of the cover 55.

  Next, an operation when the slide door 1 is opened and closed will be described. 4 and 5, when the slide door 1 is in a closed state (closed state), the bending portion 53 is urged by the elastic member 52 and is arranged along the regulating wall 57 (curved during traveling). The part 53 does not flutter and no sound or vibration is generated). The door-side wire harness 3 (including the corrugated tube 19) is led out from the second harness outlet 61 in the portion of the extension portion 61.

  When the slide door 1 is operated from this state and the slide door 1 is in an open state (open state), the door-side wire harness 3 (corrugated tube) moved to the front of the vehicle body 2 through the second harness outlet 61. 7), as shown in FIG. 7, the bending portion 53 contracts against the urging force of the elastic member 52 in the middle of the movement (see the phantom line in FIG. 5), and the second harness is removed on the base wall 58 side. Derived from the outlet 61. Since the biasing force of the elastic member 52 is generated, the door-side wire harness 3 (including the corrugated tube 19) does not hang down below the vehicle body 2.

  As described above with reference to FIGS. 1 to 7, the door-side wire harness 3 and the protector 9 (50) are provided, and the extra length of the door-side wire harness 3 required for opening and closing the slide door 1 is described. The power supply device 10 (51) for a sliding door for an automobile in which the minute portion is a curved portion 20 (53) and this is accommodated in the protector 9 (50) simplifies the configuration and improves the assemblability. In addition, the space occupied by the power feeding device 10 (51) is determined in consideration of the range of movement of the bending portion 20 (53) relative to the inner panel 8, thereby saving space.

  In addition, it goes without saying that the present invention can be variously modified without departing from the spirit of the present invention. In addition, derived from the present invention, it is also conceivable to integrally form the protector main body (protective member main body) on the inner panel.

  8 to 12, the embodiment shown in FIGS. 4 to 5 has been improved so that the swing of the wire harness 3 accompanying the opening and closing of the slide door 1 can be performed more smoothly and without generation of abnormal noise or the like. A power supply device 51 'for a sliding door for automobiles is shown. The same components as those in FIGS. 4 to 5 are denoted by the same reference numerals, and detailed description thereof is omitted.

  The power feeding device 51 ′ of the present embodiment includes an inclined contact portion 72 and an inclined sliding member that smoothly contacts or slides the door-side wire harness 3 on the front and rear end sides of a protector (curved portion protecting member) 50 made of synthetic resin. The contact portions 73 to 75 are formed.

  That is, as shown in FIGS. 8 to 10, a vertical side wall of a substantially inverted U-shaped base wall 58 ′ below the first harness outlet 60 on the front end side of the protector body 54 ′ fixed to the inner panel 8. An inclined contact portion 72 is formed from the portion 58b ′ (FIG. 10) to the substantially block-shaped lower wall portion 58c ′.

  The inclined contact portion 72 is, for example, a tapered inclined surface (inclined contact surface) in the same direction as the lower end portion of the upper tube fixing wall 59, and this inclined contact surface 72 is the protector main body 54 '. Located inside. The lower wall portion 58c 'of the base wall 58' is formed in a substantially block shape with an increased volume. The side wall portion 58b 'of the base wall 58' is formed shorter than the side wall portion 58b of the embodiment of FIG. The substantially block-shaped lower wall portion 58c 'can be formed hollow rather than solid. In this case also, of course, it has an inclined contact surface 72 and an inclined sliding surface 73 described later.

When the wire harness 3 to the fully open state of the sliding door 1 as shown in FIG. 9 is inclined while curving smaller pulled forward as chain line 3 _1, it abuts against the obliquely along the inclined contact surface 72, impact The power is relaxed and the generation of abnormal noise is prevented. For example, when the wire harness 3 is brought into contact with the side wall portion 58b of the inclined contact surface 72 without the base wall 58 (see FIG. 5) in the state of chain line 3 _1, perpendicular wire harness 3 ₁ with respect to the longitudinal direction There is a concern that it will hit the side wall 58b and generate an impact sound. The inclined contact surface 72 eliminates this concern. By wire harness 3 is slanted to the surface contact with the inclined contact surface 72 as the chain line 3 _1, the impact force acting on the wire harness 3 ₁ is reduced, Ya addition to the wire harness 3 ₁ variant of noise Damage is prevented. Wire harness 3 ₁ is derived from the second harness outlet 61 of the lower to the vehicle body.

A first harness outlet 60 on the front side is formed by the long upper wall portion 58a of the substantially inverted U-shaped base wall 58 'and the curved protruding portion of the upper regulating wall 57. As chain line 3 ₃ of Figure 9, the wire harness 3 to the fully closed sliding door 1 is pulled rearward located along the rear extension portion 62 of the protector body 54 ', the second harness outlet 61 of the lower Derived to the vehicle body side. The wire harness 3 is fixed to a fixed position on the vehicle body side, that is, the vertical wall 17 on the rear end side of the step 16 (FIG. 8) in this embodiment.

  As shown in FIGS. 9 and 10, an inclined sliding contact portion (inclined sliding contact surface) 73 facing the vehicle body is formed on the lower end side of the lower wall portion 58c ′ of the base wall 58 ′ of the protector body 54 ′. Has been. The inclined slidable contact surface 73 continues to intersect the inclined contact surface 72, and tapers from the horizontal lower end surface 58d (FIG. 10) of the lower wall portion 58c 'to the vertical side surface 58e near the vehicle body. It is formed in a shape.

The slanted sliding surface 73, when the chain line 3 ₂ as the fully open time, for example, the wire harness 3 of the sliding door 1 in Figure 9 projecting forward from the strongly pulled protector body 54 'forward, the wire harness 3 ₂ is smoothly led forward without being caught, and when the wire harness 3 returns from the chain line 3 ₂ state to the chain line 3 ₁ state when the sliding door 1 is closed, the wire harness 3 ₂ is smoothly pulled backward without being caught. It serves to move. By moving (swinging) the wire harness 3 ₂ without being caught, abnormal noise, wear or damage to the wire harness 3 ₂ are prevented. The wire harness 3 includes a corrugated tube 19 or other protective tube. Even in the case where the protective tube 19 is not used, the above-described effect is similarly achieved.

  As shown in FIG. 8, the protector body 54 ′ includes a substantially semicircular vertical substrate portion 56, a regulation wall 57 around the substrate portion 56, the base wall 58 ′, and a rearward extension portion 62, and the front side thereof The first harness outlet 60 has a wide second harness outlet 61 on the lower side. The protector body 54 'is fixed to the inner panel 8 with bolts 65 or other locking means. A front portion of the wire harness 3 is led out from the first harness outlet 60, and the electric wire 18 in the front portion is connected to an electrical component or the like (not shown) in the slide door 1 by the connector 4. Further, the rear portion of the wire harness 3 is led out from the lower second harness outlet 61 and is connected to the vehicle body side wire harness 6 by connectors 5 and 7. In FIG. 8, reference numeral 64 is a mounting flange, and 15 is a hinge roller.

  In FIG. 8, a cover 55 'is attached to the protector main body 54', and is fixed to the protector main body 54 'with one touch by a locking means or the like (not shown). The cover 55 ′ has a vertical board portion 68, a peripheral wall 69, a front lower side wall 70, a rear extension 76, and a reverse vertical cross section that forms the first harness outlet 60 between the peripheral wall 69 and the side wall 70. A character-like forwardly protruding portion 77 and a curved flange 71 on the lower end side of the board portion 68 are provided, and inclined sliding contact portions 74 for guiding the wire harness are provided at the front end lower portion and the rear end lower portion, respectively. , 75 are formed.

  The front-side inclined sliding contact portion 74 is formed by notching the substrate portion 68 and the flange portion 71 in a tapered shape obliquely downward from the lower end side of the side wall 70 toward the rear. The inclined sliding contact portion 74 is preferably formed linearly or continuously in a curved shape on the substrate portion 68 and the flange portion 71. In the case where the flange portion 71 is greatly curved and serves also as a part of the substrate portion 68, the inclined sliding contact portion 74 may be provided only on the flange portion 71.

It can be moved backward smoothly without being caught along the slanted sliding contact portion 74 of the wire harness 3 ₂ protruding from the inside of the side wall 70 to the front cover 55 as the chain line 3 ₂ '(FIG. 8) in FIG. 9 . As a result, an increase in operating force when the slide door 1 is closed can be prevented, operability can be improved, and scratching can be prevented. The caught wire harness 3 _2, there is a concern that results in increased or rubbing sound operation force.

  The front inclined sliding contact portion 74 is positioned substantially opposite to the front inclined sliding contact portion 72 on the protector main body 54 ′ side, and the synergistic effect of both inclined sliding contact portions 72 and 74 damages the wire harness 3. Deterioration of the attachment and the operability of the sliding door 1 is surely prevented.

  The inner surface of the front side wall 70 of the cover 55 'is located along the front side of the base wall 58' of the protector body 54 ', and at least the side wall 58b' of the base wall 58 ', the inclined contact part 72 or the inclined contact. The upper half side of the portion 72 is accommodated inside the side wall 70.

  As shown in FIG. 8, the rear inclined sliding contact portion 75 is formed at the rear end portion of the rear extension 76 of the cover 55 ′. As shown in the enlarged view of the main part in FIG. 11, the rear sloping sliding contact portion 75 is inclined diagonally downward from the upper wall 78 of the rear extension 76 toward the front, and the vertical substrate portion 79 and the curved saddle. The portion 71 is cut out in a curved or tapered shape. Thus, it is preferable that the collar part 71 is also notched integrally. In the case where the rear inclined sliding contact portion 75 has a curved shape, the center of bending is located at the upper front portion of the rear extension 76 and is curved outward from the rear end 78a of the upper wall 78. The inclined sliding contact portion 75 follows the curved flange portion 71, and the second harness outlet 61 (FIG. 8) is located inside the flange portion 71.

The rear end of the rear extension portion 76 is opened, the wire harness 3 as chain line 3 ₃ of Figure 9 are derived from the extension portion 76 to the rear. The rear end of the upper wall 78 of the extension 76 is curved upward, the wire harness 3 ₃ along the curved portion 78b from the extension portion 76 is obtained by a bendable smoothly upwards.

Wire harness 3 derived rearward from the rear extension 62 to fully closed sliding door 1 as dashed line 3 ₃ of FIG. _{9. 3,} sloped side of the cover 55 of Figure 8 'during operation opening the sliding door 1 It is smoothly guided without being caught obliquely downward from above along the sliding contact portion 75, and moves while sliding forward along the curved flange 71. Since it is possible to wire harnesses 3 ₃ moves forward without being caught, increasing the opening operation force of the sliding door 1 is prevented, with smooth opening operation is performed, Ya scratches or deformation by being caught in the wire harness 3 ₃ Generation of abnormal noise is prevented.

As shown in the chain line of FIG. 11 and FIG. It is also possible to form by cutting into a curved shape. According to this, prevents snagging of the rear outer corner portions 78c of the upper wall 18 (FIG. 11) the wire harness 3 ₃ (FIG. 9) is, it is possible to further move smoothly the wire harness 3 _3.

  The cover 55 'and the protector body 54' can be integrally formed of a synthetic resin material. In that case, the peripheral wall 69 of the cover 55 ′ and the regulating wall 57, which is the peripheral wall of the protector body 54 ′, are integrated, and the upper wall 78 of the rear extension 76 of the cover 55 ′ and the rear extension 62 of the protector main body 54 ′. The inclined contact portion 72 and the inclined slidable contact portions 73 to 75 are formed on the base wall 58 ′ and the rear extension 76 of the protector 50 ′ by integrating with the wall. Moreover, it is also possible to apply the inclined contact portion 72 and the inclined sliding contact portions 73 to 75 to the protector 9 of the embodiment of FIG. In each of the above embodiments, the protectors 9, 50, 50 'can be arranged on the vehicle body side.

  FIG. 13 shows another embodiment of the protector (curved portion protection member).

  The protector 81 includes a protector main body (protective member main body) 82 made of a synthetic resin and a cover (not shown). The protector main body 82 has a first harness outlet 83 at the upper front end of the protector main body 82, and the front portion of the protector main body 82. On the side, a substantially loop-shaped bending restriction wall (bending restriction portion) 88 for the elastic member 85 and the wire harness 86 (including the corrugated tube 87) is provided inside the curved restriction wall 84, and the first harness The outlet 83 is provided with a harness fixing portion (fixing portion) 89 for fixing the corrugated tube 87 on the outer periphery of the wire harness.

  The restriction wall 84 is an outer peripheral wall orthogonal to the outer periphery of the board portion 90, and includes a short inclined straight portion 84a that follows the first harness outlet 83, a substantially arc-shaped curved portion 84b that follows the straight portion 84a, and a rear side. And a hem portion 84c. The harness fixing portion 89 is formed integrally with the straight portion 84a.

  Further, the bending regulating wall 88 is positioned adjacent to the rear of the harness fixing portion 89, and has a substantially semicircular upper half 88a and a substantially bow shape that extends forward from the rear end side of the upper half 88a. The lower half 88b is curved. “Front and rear” means “front and rear” of the vehicle. The front end side of the lower half portion 88 b is inclined substantially linearly downward and intersects the front end wall 91 in the vertical direction of the protector body 82. The bending restriction wall 88 is erected from the base plate portion 90 at the same height as the outer peripheral wall 84 and the front end wall 91.

  A portion on the front end side of the upper half portion 88a adjacent to the harness fixing portion 89 has a short vertical straight portion 88c, and a base end portion of a metal leaf spring which is an elastic member 85 is a bracket below the straight portion 88c. It is fixed to the substrate part 90 with a metal-like fixture 92. A cutout portion (not shown) is provided at the base end portion of the elastic member 85, the fixing portion 93 at the center of the fixture 92 is engaged in the cutout portion, and the hole portion 94 of the fixture 92 is a bolt (not shown). ) Or a resin projection (not shown) of the substrate 90 is fixed by thermal welding or the like.

  The fixture 92 is located at the center of the front end portion of the protector body 82 in the height direction, and the upper half 88a of the bending restricting wall 88 is located at about half the total height of the protector body 82. . Further, the harness fixing portion 89 is positioned substantially opposite to the upper side of the fixture 92, and the upper end portion of the bending restriction wall 88 is positioned higher than the harness fixing portion 89.

  The elastic member 85 is raised along the vertical straight portion 88 c of the bending restriction wall 88 and is bent backward in an arcuate shape in contact with the lower surface of the wire harness 86. The wire harness 86 is introduced into the protector main body 82 from the first harness outlet 83, is routed in a curved shape along the outer surface of the elastic member 85, and is lowered on the rear end side along the hem 84c of the protector main body 82. The second harness outlet 94 on the side is led out to the vehicle body side (not shown). In this state, the sliding door (not shown) is almost fully closed. During the opening and closing of the sliding door, the wire harness 86 can be bent along the inner surface of the outer peripheral regulating wall 84.

  For example, other functional parts (not shown) can be arranged in the internal space 95 surrounded by the substantially loop-shaped bending regulating wall 88. A window portion 96 is provided in the substrate portion 90 so as to communicate with the internal space 95. For example, the protector body 82 can be temporarily assembled (temporarily fixed) to the slide door using the window portion 96. The outer peripheral surface of the bending restriction wall 88 is formed of a smooth surface without a bulge, and a frame-like portion 97 for locking is formed at several locations on the inner peripheral surface side of the bending restriction wall 88, and slits in the frame-like portion 97 are formed. A locking claw of a cover (not shown) is engaged with the hole. The bending restriction wall 88 is supported from the inside by the frame-shaped portion 97, and the bending rigidity of the bending restriction wall 88 is increased.

  Several frame-like portions 97 are also provided outside the outer peripheral wall 84 and the front end wall 91. The main fixing of the protector main body 82 to the slide door is performed by tightening the slide door panel with bolts (not shown) through the holes 98 on the inner side of the bending restriction wall 88 and the holes of the bracket 99 protruding from the outer peripheral wall 84. Done in As shown in FIG. 14 (C-C cross-sectional view of FIG. 13), the harness fixing portion 89 has rib-shaped protrusions (projections) 100 that engage with the concave grooves of the corrugated tube 87 on the outer periphery of the wire harness 86. The corrugated tube 87 is fixed in the longitudinal direction.

  In the embodiment shown in FIG. 14, a corrugated tube 87 having an oval cross section is used. The corrugated tube 87 has grooves and ridges in the circumferential direction alternately in the longitudinal direction, and the ridges 100 that engage with the grooves are standing on the inner surface of the outer peripheral wall 84 and the outer peripheral wall 84. Two or three of the inner surface of the rising wall 101 and the bottom wall 102 that smoothly connects the outer peripheral wall 84 and the rising wall 101 are provided in parallel in a substantially U-shape. The protrusion 100 fixes the wire harness 82 in the vicinity of the first harness outlet 83 by the same action as the two protrusions for fixing the corrugated tube provided on the fixing wall 59 of FIG.

  The rising wall 101 is provided at a right angle from the substrate portion 90, and the bottom wall 102 is positioned one step higher on the cover side than the substrate portion 90, and the rising wall 101 and the outer peripheral wall 84 are arranged along the outer peripheral shape of the corrugated tube 87. Followed by a curved shape. The ridges 100 are also curved along the outer peripheral shape of the corrugated tube 87. On the outer surface of the rising wall 101 and the outer surface of the outer peripheral wall 84, a frame-like portion 97 for locking the cover is provided.

  It is also possible to provide a protrusion on the inner surface of a cover (not shown) facing the protrusion 100. When a corrugated tube (not shown) having a circular cross section is used, the bottom wall 102 and the protrusions 100 on the bottom wall are formed in a semicircular shape. Although the number of the protrusions 100 is arbitrary, two to three are preferable from the viewpoint of facilitating the operation of engaging the concave grooves of the corrugated tube 87 with the protrusions 100. It is also possible to prevent the corrugated tube from twisting by supporting a corrugated tube (not shown) having a circular cross section along the protrusion 100 so as to be rotatable in the circumferential direction.

  With the configuration in which the bending restriction wall 88 is provided, the wire harness 86 and the elastic member 85 can be connected to each other when the wire harness 86 is pulled forward together with the elastic member 85 while being largely bent downward when the sliding door is opened. Since the wire harness 86 and the elastic member 85 are bent along the bending restricting wall 88 and the bending of the wire harness 86 and the elastic member 85 at an angle larger than that is prevented, the wire harness 86 and the elastic member 85 may be bent, plastically deformed, damaged, or damaged. Is prevented.

  The outer diameter and shape of the bending restriction wall 88 are within a range in which the elastic member 85 is supported within the allowable elastic limit and the wire harness 86 is not bent at an acute angle, and the wire harness 86 and the elastic member 85 are not bent. It is not possible to bend at a radius smaller than 88 bend radius. By preventing the elastic member 85 from being damaged, the slack of the wire harness 86 is always reliably absorbed in the protector 81 when the slide door is opened and closed (the wire harness 86 is always elastically biased upward), and the vehicle body and the slide door The wire harness 86 is reliably prevented from being caught between the two.

  Even if the elastic member 85 is damaged due to fatigue or the like, the wire harness 86 is supported in a curved shape along the bending restricting wall 88 and is always lifted to a certain level or higher. The second harness outlet 94 on the lower side is not pulled out more than necessary, and pinching of the wire harness 86 between the vehicle body and the sliding door is prevented (reduced).

  Since the first harness outlet 83 is arranged on the upper side or the upper side of the protector 81 in substantially the same manner as in the embodiment of FIG. 1, the wire harness 86 introduced into the protector from the first harness outlet 83 is bent immediately. It is supported by the restriction wall 88, thereby preventing excessive bending of the wire harness 86 and the elastic member 85. When the first harness outlet 83 is on the lower side of the front end of the protector 81, the wire harness 86 is bent largely (at a tight bending angle), whereas in the present embodiment, this is prevented, and the wire harness 86 is impossible. Bending stress does not act.

  Further, since the wire harness 86 can be easily fixed by the harness fixing portion 89, the wiring and fixing workability of the wire harness 86 to the protector 82 is improved, and the wire harness 86 is firmly fixed to the harness fixing portion 89. Therefore, even when the wire harness 86 is strongly pulled by sudden opening / closing of the slide door, the wire harness 86 is not pulled into the protector 81 from the first harness outlet 83, and the wire harness 86 is loosened. The elastic member 85 always reliably absorbs the slack of the wire harness 86, and reliably prevents the wire harness 86 from being caught between the vehicle body and the sliding door.

  Note that it is also possible to configure the bend restricting portion by arranging a plurality of pin-shaped or plate-like protrusions (not shown) in the shape of the bend restricting wall 88 in place of the bend restricting wall 88. Further, the bending restriction wall 88 does not necessarily have to be continuous, and a plurality of curved short bending restriction walls (not shown) can be arranged to form a bending restriction portion. In addition, when a protective tube (not shown) having no concave groove is used instead of the corrugated tube 87, the harness fixing portion 89 can be changed to another form such as a band or a clamp.

  Further, the protector 81 shown in FIG. 13 may be provided with inclined sliding contact portions 73 to 75 of the protector 51 ′ shown in FIG. The inclined contact portion 72 in FIG. 8 corresponds to the inclined portion 88d on the lower end side of the bending regulating wall 88 in FIG.

  FIGS. 15-16 shows 3rd embodiment of the electric power feeder of the sliding door for motor vehicles. In this power supply device 110, instead of the second embodiment of FIG. 4, a protector 111 made of synthetic resin is arranged on the vehicle body 2 side instead of the slide door 1 side, and the wire routed from the slide door 1 to the vehicle body 2 The harness 112 is loosened and absorbed by the elastic member 52 in the protector 111 on the vehicle body 2 side.

  In this embodiment, the protector 111 is disposed horizontally below the step portion 16 of the vehicle body 2. The protector 111 has a shape in which the rear side 113 extends linearly toward the slide door 1 and the front side 114 gradually decreases in a curved shape and extends forward, and has a substantially horizontal concave cross section. A first harness outlet 115 is provided on the end side, and a second harness outlet 116 that is linearly wide open on the side facing the slide door 1 side. The protector 111 is fixed to the vehicle body 2 with a bracket 117.

  The elastic member 52 extends from the rear side (the first harness outlet 115 side) of the protector 111 to the middle in the longitudinal direction of the protector 111, and the wire harness 112 is routed along the elastic member 52. The base end portion of the elastic member 52 is fixed to the protector 111 with a fixing tool 118 or the like. The shape of the elastic member 52 is not limited to a leaf spring shape, and various forms of elastic members (not shown) can be used. The material, shape, and position of the protector 111 can be changed as appropriate. The protector 111 is preferably composed of a protector body and a cover from the viewpoint of harness assembly workability. It is also possible to provide the protector 111 with an inclined contact portion 72 and inclined sliding contact portions 73 to 75 similar to those in FIG.

  In the fully closed state of the sliding door 1 in FIG. 15, the wire harness 112 is pulled forward along the curved portion (represented by reference numeral 114) of the protector 111, and the elastic member 52 is slightly bent while pulling the wire harness 112 of the vehicle body 2. It is energized toward the passenger compartment.
