  By the way, in the above-described conventional sliding door power supply structure, when the sliding door D is opened and closed, the positional relationship between the sliding door D and the electric wire W is as follows. FIG. 8 is a schematic diagram showing a positional relationship between the slide door D and the electric wire W when the slide door D is opened and closed. In FIG. 8, this positional relationship is shown in a sectional view along a cut surface of the slide door D parallel to the scuff trim ST on the vehicle floor. FIG. 8A shows the sliding door D that is opened to some extent. Further, FIG. 8B shows the slide door D immediately after the protrusion at the time of opening or just before the full close, and FIG. 8C shows the slide door D in the fully closed state.

  As shown in FIG. 8, when the slide door D is opened, the contact portion PA between the electric wire W and the door trim T moves forward of the vehicle in the slide door D along with the opening operation. The contact angle θA with the door trim T increases. Conversely, when the slide door D is closed, the contact angle PA decreases as the contact portion PA moves rearward of the vehicle in the slide door D along with the closing operation.

  Then, at the time of transition to the fully closed state shown in FIG. 8C, or when going from the fully closed state to the open state, the contact angle θA becomes small and the electric wire W becomes the lower end of the door trim T. When extending substantially parallel to the edge, the portion extending in parallel tends to be caught on the lower edge of the door trim T. Stress is accumulated in the wire W thus caught, and the wire W climbs over the lower end edge of the door trim T at a stage when the stress reaches a certain level. And when the electric wire W climbs over the lower end edge of the door trim T at once, there is a problem that the vibration of the electric wire W at that time resonates as a noise to the passenger's ear.

  Here, a kick-up portion described below is provided on the vehicle rear side of the lower end edge of the door trim T. FIG. 9 is a view showing a kick-up portion provided at the lower end edge of the door trim T. As shown in FIG. As shown in FIG. 9, a scuff trim ST is installed on the floor of the vehicle, and the kick-up portion K extends upward so that the lower end edge of the door trim T on the vehicle rear side is away from the scuff trim ST. It is a portion formed by rising at a kick-up angle θK.

  Conventionally, in order to prevent the electric wire W and the lower end edge of the door trim T from being caught when the sliding door D is opened and closed, the kick-up portion K is made large to increase the gap Ar between the scuff trim ST and the door trim T. There are many. However, such an increase in the gap Ar has a problem that the appearance of the slide door D is lowered.

  In view of these circumstances, the present invention provides a power supply structure for a slide door that can suppress abnormal noise caused by the vibration of an electric wire when the slide door is opened and closed and can improve the appearance of the slide door. Let it be an issue.

  In order to solve the above-described problem, the sliding door feeding structure according to claim 1 is a sliding door feeding structure in which an electric wire is routed between the vehicle body and the sliding door to feed power.
