PURPOSE:To aim at simplifying the overall structure and control of a carrier vehicle by arranging a flexible tube in the moving direction of the carrier vehicle, by engaging rollers to the carrier vehicle in a direction orthogonal to the tube, and by feeding pressure fluid into the tube in a one-way direction so as to drive the carrier vehicle by means of the rollers. CONSTITUTION:A flexible tube 3 is disposed along the moving direction of a carrier vehicle 10, and in addition to running wheels 11, rollers 2 are provided to the carrier vehicle in a direction orthogonal to the flexible tube 3 so that the tube 3 is disengageably held between both side flanges of the rollers 2. When pressure fluid 4 is fed into the flexible tube 3 in a one-way direction, the flexible tube 3 expands. Pressure fluid is successively fed to drive the carrier vehicle 10 in a one-way direction through the rollers 2. Thereby it is possible to simplify the overall arrangement of the carrier vehicle in comparison with those using a drive motor, rollers, hydraulic pressure and the like, and to reduce noise during drive of the vehicle. Further, it is possible to simplify the overall control of the carrier vehicle by change-over of pressure fluid. |
