Abstract

A power supply device includes a rotation retainer including an inlet horizontally guiding the electrical wire one end of which is connected to the vehicle, and an outlet communicating with the inlet and to draw out upwardly the other end of the electrical wire, the rotation retainer being arranged horizontally pivotally in the slide door to retain the electrical wire movably, a biasing member configured to bias the rotation retainer in a predetermined rotational direction, wherein the electrical wire includes a bending portion to be bent in an L-shape between the inlet and the outlet, and a guide portion to be wired nearer the outlet than the bending portion, and wherein the guide portion is arranged in a natural state in which the guide portion is not twisted, or a twisted state in which restoring force is generated in a same direction as a biasing direction of the biasing member.

First claim

The invention claimed is:

1. A power supply device supplying power by wiring an electrical wire, to a slide door slidable between a closed position where an opening of a vehicle is fully closed and an opening position where the opening of the vehicle is fully opened, the power supply device comprising:
a rotation retainer including an inlet horizontally guiding the electrical wire an end of which is connected to the vehicle, and an outlet configured to communicate with the inlet and to draw out upwardly an another end of the electrical wire, the rotation retainer being arranged horizontally pivotally at the slide door so as to movably retain the electrical wire; and
a biasing member configured to bias the rotation retainer in a predetermined rotational direction, wherein

the electrical wire includes a bending portion where the electrical wire is bent in an L-shape between the inlet and the outlet, and a guide portion located nearer the outlet than the bending portion, and wherein
in a condition in which the slide door is arranged in the closed position, the guide portion is arranged in a natural state in which the guide portion is not twisted, or a twisted state in which restoring force is generated in a same direction as a biasing direction of the biasing member.

2. The power supply device according to claim 1 further comprising an electrical wire fixing portion configured to fix the guide portion of the electrical wire at a side separated from the bending portion.
