PROBLEM TO BE SOLVED: To install a closed-loop-like electric path in a track so that two or more guided vehicles can travel simultaneously with a space between them, while permitting the detection of a preceding guided vehicle even in a curved part. SOLUTION: A wire 21 of closed loop is installed in the track 2, and the guided vehicle 10 is equipped with a power generation coil 12 and a power receiving coil 13. A current passing through the wire 21 with the power generation coil 12 of the preceding guided vehicle 10D is detected with the power receiving coil 13 of the succeeding guided vehicle 10C, so that the succeeding guided vehicle 10C detects the preceding guided vehicle 10D. Two or more wires 21 are juxtaposed along the traveling direction of the guided vehicle 10. COPYRIGHT: (C)2004,JPO
