<p>PURPOSE:To make the curvature of the portion of a winding running path sufficiently small while the length of a secondary conductor being made suffi ciently long. CONSTITUTION:A guide rail B through which a carrying body is supported in such a way as to be freely moved, is provided, a primary coil and a secondary conductor D are provided for the guide rail side and the body side respectively, and the secondary conductor D is divided so as to be formed into a plurality of conductor portion D1 and D2 which are lined up in the lengthwise direction of the body. In this case, these conductor portion D1 and D2 are provided in such a way as to be freely flexible and be flexibly operated in a position along the longer direction of the guide rail, B by means of rollers 8 guided by the guide rail B where the paired front and rear rollers 8 are disposed at both the sides of each conductor body D1 positioned at the front and rear end sections of the body out of a plurality of the conductor portions D1 and D2 in a state that they are moved integrally with the conductor portion D1.</p> |
