PROBLEM TO BE SOLVED: To provide a road-rail vehicle capable of safely traveling on rails in time of emergency.SOLUTION: A rocking frame to which a steel wheel support member that supports a steel wheel for rail traveling is connected, is rockably supported by a sub-frame, and rocking is locked by expansion of a rocking locking cylinder. The rocking frame is unlocked by energizing an unlocking solenoid SOL41b of a hydraulic solenoid valve 41. The unlocking solenoid SOL41b is connected to an operation unit 60 via a controller 70 and also directly connected to an emergency switch 80. When an operation of unlocking rocking of the rocking frame is carried out by the operation unit 60, the controller 70 outputs a control signal to energize the unlocking solenoid SOL41b if the controller 70 determines satisfaction of a predetermined condition. When an operation of turning on the emergency switch 80 is carried out, the unlocking solenoid SOL41b is switched into an energized state. |
