PURPOSE:To detect deviation from an orbit, to attain orbit travel control and to achieve continuous secure travel control even at a branch or confluence by fitting a detector to a vehicle running on a belt-like rubber magnetic orbit in a floor. CONSTITUTION:An orbit belt-like rubber magnet M is stuck to the floor to produce the travel orbit for an unmanned vehicle, which is equipped with a magnetic sensor circuit DA as the detector detecting the position of the belt-like magnet and switch circuits DL, DG and DR. The circuit DA outputs an analog voltage as an output, and the switch circuits DL, DG and DR generate on/off signals L, G and R after they detect the position of a magnetism generating body. Thus the orbit travel of the unmanned vehicle can be controlled correctly and continuously, and simultaneously the vehicle can move to a right or left orbit so that it can continuously travel at the branch or confluence on the belt-like magnetic orbit. Namely the output signals A, G, L and R generated by the detector detect the deviation from the orbit to control the orbit travel, and the vehicle can travel surely and continuously even at the branch, etc.
