PURPOSE:To obtain a stable running state by constituting the titled car so that a wheel for rotating freely is provided on the center part of a car body so that a front wheel and a rear wheel always run on a route. CONSTITUTION:At the time of a forward run, a front driving motor 13 is started in a state that an electromagnetic clutch 14 has been connected, and a forward run is started. In that case, a rear driving motor 20 remains stopped, also an electromagnetic clutch 21 is in a disconnected state, and a rear wheel 19 continues a driven rotation on a route 1. Sensors 23, 24 also continue its operation, and when the rear wheel 19 slips out of a route 1, an operating signal is sent to a steering motor 22, and the rear wheel 19 is returned automatically onto the route 1. In case of a backward run, the electromagnetic clutch 21 is connected and a backward run control motor 20 is operated, in reverse to the case of the forward run, the electromagnetic clutch 14 is disconnected and the front driving motor 13 is stopped. Sensors 16, 17 continue its operation, and a steering motor 15 is controlled so that a front wheel always runs on the route 1.
