PROBLEM TO BE SOLVED: To provide an amphibian vehicle by constituting the crawler belt for a buoyancy body to generate buoyancy, and supporting the weight of the vehicle on water by the buoyancy. SOLUTION: This vehicle has a lateral pair of crawler devices formed of a frame 101, a rubber belt 102, a foamed plastic-made buoyancy body 103 having a trapezoidal section which is adhered to the rubber belt 102, a front roller 104a, a rear roller 104b, and shafts 105a and 105b and brake devices 106a and 106b for both the rollers. This vehicle is travelable on water and ground by the propulsive force of a propeller device 110 driven by an engine. The weight of the vehicle can be supported on water by the buoyancy of the crawler. Further, since the relative speed of the crawler in contact with the water surface in water traveling to the water surface is smaller than the traveling speed of the vehicle, the wave drag can be minimized to reduce the fuel consumption.
