  FIG. 1 shows an embodiment of a power supply harness routing structure according to the present invention.

  In this power supply harness routing structure, a horizontal rail portion 1 is provided on the sliding door side of an automobile, a slider 2 is slidably engaged with the rail portion 1, and a swing member 3 is freely swingable in the horizontal direction. The harness fixing tool (harness fixing part) 4 is provided in the vehicle body, the corrugated tube (protective tube) 6 of the wire harness 5 is routed horizontally from the swinging member 3 to the harness fixing tool 4, and the corrugated tube 6 The stopper member 14 is fixed to the middle portion in the longitudinal direction, and a protrusion (engagement portion) 15 with respect to the stopper member 14 is provided on the vehicle body side so that the stopper member 14 contacts the convex portion 15 when the sliding door is opened. Thus, separation of the corrugated tube 6 from the vehicle body side to the slide door side is suppressed.

  The rail portion 1 is formed shorter than the conventional one (FIG. 8), and is fixed to, for example, a door inner panel or a case (not shown). A part of the vertical back wall 8 is slidably engaged with the rail portion 1, the slider 2 has a vertical hole portion 10 for inserting a harness in the upper wall 9, and a neck between the upper wall 9 and the lower wall 11. A concave space for mounting the swing member 3 is provided.

  The swinging member 3 is supported by the upper and lower walls 9 and 11 of the slider 2 so as to freely swing (rotate) in the horizontal direction, and has a hole 12 for inserting a harness in the 90 ° direction following the hole 10 of the upper wall 9. The corrugated tube 6 is held and fixed in the hole 12. It goes without saying that a plurality of insulating coated electric wires 13 are inserted into the corrugated tube to constitute the wire harness 5.
