PURPOSE:To automatically branch the running body to the selected indication direction given to the short-circuit, by providing the trolley line group and added branching short-circuit with the branched part and providing a simple electric circuit to the running body. CONSTITUTION:The running body 5 receives the power supply from the main running path 1, trolley lines 6,6', trolley lines 7, 7', 8,8' of the first and second branch lines 2,3. At the branch point, the trolley lines 13,13' for nonpower-supply bracnch are provided via the isolation sections 11,11' 12,12' and at the center, the trolley lines 15,15' are provided. The endless rotation magnetic substance belts 18,18' are provided at the branch path, and when the fields 22,22' of the running body 5 are selectively excited with the switch 24, the running body 5 is selectively absorbed. Further, the running body is brached and run toward B or C with the revolution of the endless magnetic substance belt, not shown.
