Abstract
An amphibious vehicle includes a vehicle body; a flap supported at a lower portion in a traveling direction of the vehicle body to be able to swing in a direction in which an upper edge portion approaches and separates from the vehicle body; a support column which has a fluid actuator capable of expanding and contracting in accordance with a pressure of a working fluid to a cylinder chamber, is connected to the flap in at least a first end portion in a longitudinal direction, and performs adjustment of a swinging angle of the flap by expansion and contraction of the fluid actuator; a power source which supplies the working fluid to the cylinder chamber; and a safety valve which communicates with the cylinder chamber, and opens when an internal pressure of the cylinder chamber becomes greater than a predetermined pressure to discharge the working fluid in the cylinder chamber.
