Abstract: PURPOSE:To prevent a transport device from being excessively large by providing a plurality of struts supported vertically movably on a flat ship and supporting on the lower ends rotatable wheels detachably about the lateral axes respectively and also providing a means for urging the struts to the bottom side of the water. CONSTITUTION:Transport devices 11 for holding a flat ship 2 at a predetermined position on the water and transporting it on the water are respectively provided on the front and rear portions at both broad sides of the flat ship 2. When the flat ship 2 is transported in the desired direction, the turning hydraulic motor 34 of a turning device 23 is first driven to rotate the outer ring 31a of a turning bearing so that a wheel 16 at the lower end of a strut 15 is directed in the desired advancing direction. Next, a lifting/lowering hydraulic motor 38 is driven to move the strut 15 downward and urge the wheel 16 toward the water bottom. And a travelling hydraulic motor 18 is driven to rotate the wheel 16 so that the flat ship 2 is moved in the desired direction. Thus, since loads from the flat ship can be shared by the respective struts and wheels, the strength of these struts and wheels can be lessened and a drive force of a single wheel can be reduced.
