PURPOSE:To improve a current collecting effect, by a method wherein end faces, which make overlapping contact with each other in a manner that the forwardmost end position of the one face and the forward end position of the other end face are shifted in reverse directions when they are abut on to each other for juncture, are formed on and in their respective feeders. CONSTITUTION:A square cone part 1c or a chevron projection 1d is formed on an end face 1a of one feeder 1, a recess 1c' or 1d', which engages with the end face 1a, is formed in an end face 1a' of the other feeder 1', the two feeders 1 and 1' engages with each other for firm adhesion, and the two end faces are locked by means of a screw, where necessary. The feeder 1 so formed is covered at both sides and its upper surface with an insulating material 2 to form an insulated trolley, and a position detecting sensed piece 3, such as bar code, magnetic ink, and magnet, is stuck to the side thereof. This minimizes a gap at the juncture part of the feeder, improves the following ability between a current collecting probe and the feeder, and prevents intermittent separation of the current collecting probe from the feeder, resulting in improvement of a current collecting effect. |
