Abstract

PROBLEM TO BE SOLVED: To prevent a malfunction and a short circuit by arranging a power supply bar having one polarity among power supply-signal bars of a trolley wire so as to pass through on the rotary axis of a rotary rail, and arranging power supply bars having other polarity on both sides of the power supply bar having one polarity. SOLUTION: When a bar 21a in a trolley wire in a partition rail 4 and a rotary rail 3 mutually adjusted in a straight line shape is used as a cathode and two bars 21b and 21b' on its both sides are used as anodes, if only brushes 36a and 36b exist, a current collecting piece of a panel to move in the respective rails 4 and 3 is directionally is changed through the rotary rail 3 or the like of a traveling device 12, and is slidingly contacted with the anode bar 21b' even if the brush 36b is displaced to a prescribed position. Therefore, even if the direction of the rotary rail 3 changes by turning by 180 degrees, polarity of a power source received by the current collecting piece side copes with polarity to be originally received. Therefore, reliable power supply can be attained.
