Because.

  Thus, when the slide door 9 is slid forward and closed from the fully open state of the slide door 9 in FIG. 1, the harness exterior member 5 on the slide door side has the bent portion 5 a when the slide door 9 in FIG. 1 is fully opened. It is guided (motivated) to bend to a smaller diameter together with the bent portion 6c of the corrugated tube 6, and a small-diameter bending operation of the harness exterior member 5 when the slide door 9 of FIG. Is smoothly and reliably performed without buckling or bending, and the bending durability of the wire harness including the corrugated tube 6 is thereby improved.

In the middle of closing the sliding door 9 by sliding it forward from the fully open state of the sliding door 9 of FIG. 1 (when the sliding door 9 of FIG. 2 is half-opened), the inner member 46 of the power supply tool 3 on the sliding door side rotates clockwise. rotates while the harness exterior member 5 connected to the bracket 59 of the inner member 46 is bent backward (indicating the bent portion by the reference numeral 5b), the pawl member 63 of the distal end side of the harness exterior member ₃ is positively The harness exterior member 5 is bent together with the corrugated tube 6 of the wire harness into a substantially U or J shape with a relatively small bending radius. The bent portion 5b has a bent center point in front of the vehicle.

  At this time, the bracket 59 of the inner member 46 in FIG. 7 and the inner connecting wall 68 of each piece member 63 of the harness exterior member 5 and the curved surface 72b on the proximal side of the rear side surface 72 (each curved surface 72b is adjacent to each other). Since the harness exterior member 5 is allowed to bend backward, the inclined surface 72a on the distal end side following the curved surface 72b is perpendicular to the adjacent piece member 63 (because it does not contact the inner surface of the vertical rear wall 67 of the piece member 63). In contact with the inner surface of the rear wall 67, the minimum bending radius of the harness exterior member 5 is defined (restricted).

  As described above, by restricting the bending radius of the harness exterior member 5 to be less than a certain degree, a large bending stress acts on the corrugated tube 6 of the wire harness and the wire body inserted into the corrugated tube. Without bending, the bending durability of the wire harness when the sliding door 9 is half open is improved. The wire harness includes at least a corrugated tube 6 and a plurality of insulation-coated electric wires inserted into the corrugated tube, and a tube or the like can be inserted in addition to the electric wires.

  When the sliding door 9 in FIG. 2 is half open, the harness exterior member 4 of the power supply 2 on the vehicle body side is orthogonal to the step 8 of the vehicle body 7 in the same manner as when the sliding door 9 in FIG. The harness portion 6b and the vehicle body are sufficiently secured by securing a sufficient gap between the harness portion (corrugated tube portion) 6b that protrudes in the direction and extends backward from the distal end side of the harness exterior member 4 and the vehicle body portion 12 behind the step. Interference with the portion 12 is prevented.

  By sliding the slide door 9 forward from the half-open state of the slide door 9 in FIG. 2, the inner member 46 (FIG. 8) of the power supply tool 3 on the slide door side faces backward when the slide door 9 in FIG. 3 is fully closed. The harness exterior member 5 that rotates clockwise and continues to the inner member 46 extends substantially linearly rearward along the slide door 9 together with the corrugated tube 6 of the wire harness (the linear portion is indicated by reference numeral 5c), The inner member 11 (FIG. 5) of the power supply device 2 on the vehicle body side rotates clockwise and the harness exterior member 4 following the inner member 11 is bent outward with a large radius together with the corrugated tube 6 of the wire harness. While following the straight portion 6e of the corrugated tube 6 (the bent portion is indicated by reference numeral 4b). The bent portion 4b has a bent center point inside the vehicle.

  From the fully open state of the slide door 9 in FIG. 1 to the fully closed state of the slide door 9 in FIG. 3, the swinging inner member 11 (FIG. 5) of the power supply device 2 on the vehicle body side and the power supply device 3 on the slide door side By connecting the harness exterior members 4 and 5 to the swing-type inner member 46 (FIG. 8), the harness exterior members 4 and 5 and the corrugated tube 6 of the wire harness inserted through the harness exterior members 4 and 5 The bending operation is performed smoothly and reliably without buckling or bending.

When the sliding door 9 of FIG. 3 is fully closed, the inner member 11 of the power supply tool 2 on the vehicle body side swings along the opening 75 in the fan shape on the left side of the outer member 10 as shown in FIG. The side wall 28a, 29a (FIG. 5) on the front and rear sides of the bracket 27 of the inner member 11 and the inner connection of each piece 36 of the harness exterior member 4 following the inner member 11 The front and rear side surfaces 43a and 44a of the wall 38 are positioned in non-contact (non-contact) with the inner surfaces of the front and rear wall portions 34 and 35 of the adjacent piece member 36, and the harness exterior member 4 is rotated clockwise. Furthermore, it is bendable and located with a margin.

  When the sliding door 9 of FIG. 3 is fully closed, as shown in FIG. 11, the inner member 46 of the power supply tool 3 on the sliding door side rotates further rearward than when the sliding door 9 of FIG. The harness exterior member 5 subsequent to 46 is positioned in parallel with the inner panel 9 a of the slide door 9.

  The front face 61a (FIG. 8) on the right side (vehicle compartment side) side 61 of the bracket 59 of the inner member 46 and the right side (vehicle compartment side) of the inner connecting wall 68 of each piece member 63 of the harness exterior member 5. Of the inner surface of the inner member 46 are contacted with the inner surface of the vertical wall portion 66 on the right side (vehicle compartment side) of the adjacent piece member 63. Inward bending of the harness exterior member 5 with fulcrum as a fulcrum (bending in which the apex of the bent portion is located on the vehicle compartment side and the bending center point is located on the slide door side) is prevented.

  This prevents the harness exterior member 5 and the corrugated tube 6 of the wire harness led out from the harness exterior member 5 from interfering with the step 8 side portion of the vehicle body 7 when the slide door 9 is fully closed. Occurrence of abnormal noise and damage to the corrugated tube 6 and the like are prevented.

  Further, when the sliding door 9 of FIG. 3 is opened from the fully closed state, the harness exterior member 4 of the power supply device 2 on the vehicle body side is only outward (bent) with the shaft portion 24 of the inner member 11 (FIG. 10) as a fulcrum. Bending of the harness exterior member 5 on the sliding door side when the sliding door 9 shown in FIG. 2 is half open by bending so that the apex of the portion 4b is located on the sliding door side and the bending center point is located on the vehicle interior side. Motivation of the bending portion (indicated by reference numeral 5b) is performed, and the bending of the harness exterior member 5 in FIG. 2 is performed smoothly and reliably without buckling or bending, thereby improving the bending durability of the wire harness.

  In the above embodiment, the inner member 11 (FIG. 5) is used for the power supply device 2 on the vehicle body side, but the inner member 11 is excluded and the harness exterior member 4 is directly connected to the outer member 10 so as to freely swing. It is also possible to do. However, in order to bend the harness exterior member 4 smoothly with a large radius and a large swing angle, the inner member 11 is preferably used. Although the corrugated tube 6 having a circular cross section can be used, it is preferable to use an oblong or flat corrugated tube 6 having a long diameter portion in the vertical direction in order to prevent sagging.

  The apparatus for supplying power to the slide structure according to the present invention increases the bending durability of the wire harness by controlling the bending of the wire harness portion close to the vehicle body, for example, when opening and closing the slide door of an automobile, and in addition to the slide When the door is opened and closed, the bending of the wire harness portion near the sliding door can also be controlled to increase the durability of the wire harness and the reliability of constant power supply.
