Abstract
A pair of travel rails (46) each having an upper surface and a lower surface are laid to extend from on the land (44) into the water (45). Main tires (12) are rotatably disposed on opposite sides of a vehicle body (1), so that they are located between the upper and lower surfaces of the travel rails (46), and so that they abut against the lower surfaces of the travel rails (46) during traveling of the vehicle body on the land. Auxiliary tires (13) are disposed on upper portions of the main tires (12) to abut against the main tires (12). The auxiliary tires (13) are adapted to abut against the upper portions of the travel rails (46) under influence of the buoyancy of the vehicle body (1) during traveling of the vehicle body in the water. Thus, the travel vehicle body (1) can continuously travel on the land and in the water by rotatively driving the main tires (12) to move the travel vehicle body (1) along the travel rails (46).
