To enlarge a collapsible flap and store the collapsible flap appropriately. In an amphibious vehicle () in which a flap () which receives lift from water in water navigation is provided to be deployable and storable at a front side in a travel direction of a vehicle body (), the flap () includes a lower flap () which is stored to come close to a front surface () of the vehicle body () and an upper flap () which is stored to come close to an upper surface () of the vehicle body (), and at least one of the lower flap () and the upper flap () includes a first flap member () and a second flap member () and is configured such that a flap length (L) in a direction orthogonal to a vehicle width direction is variable.

Amphibious vehicle

This cooling device for an amphibious vehicle includes: a heat exchanger mounted in the amphibious vehicle; a coolant introduction passage through which cooling air or cooling water can be introduced from the outside to the heat exchanger as a coolant; a cooling air discharge passage through which the cooling air having passed through the heat exchanger can be discharged to a cooling air discharge portion communicating with the outside; and a cooling water discharge passage through which the cooling water having passed through the heat exchanger can be discharged to a cooling water discharge portion communicating with the outside. The cooling air discharge passage and the cooling water discharge passage are formed such that at least the cooling air discharge portion and the cooling water discharge portion are independent of each other.

Cooling device for amphibious vehicle and amphibious vehicle

An amphibious vehicle includes a vehicle body, a prime mover, a drive wheel, a water propulsion device, a drive wheel transmission, and a propulsion transmission. The drive wheel is disposed on a front side of the prime mover. The water propulsion device is disposed on a rear side of the prime mover. The drive wheel transmission is disposed on the front side of the prime mover and transmits power from the prime mover to the drive wheel. The propulsion transmission is disposed on the rear side of the prime mover and transmits the power from the prime mover to the water propulsion device.
