Abstract: 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.

Abstract: A rear flap configuration for an amphibious vehicle includes a vehicle body, a pair of crawlers disposed on both right and left sides with respect to a traveling direction of the vehicle body, and a rear flap connected to a rear part of the vehicle body. The vehicle body has a rear surface including a departure angle surface which extends obliquely upward from a lower edge of the rear surface as the vehicle body extends rearward. The crawlers have upper surfaces positioned above the lower edge, lower surfaces positioned below the lower edge, and rear edges projecting rearward from the lower edge. The rear flap includes a flap body part having a facing edge which faces the lower edge between the crawlers and is vertically rotatably connected to the vehicle body so as to allow the facing edge to come into contact or close proximity with the lower edge.

Abstract: An amphibious vehicle according to the present invention includes a vehicle body, a traveling portion which causes the vehicle body to travel on land, a propulsion portion which causes the vehicle body to travel on water, a power portion which provides power to the traveling portion and the propulsion portion, and a cooling portion which cools the power portion. The cooling portion includes a first cooling source introducing portion which takes in air from the outside and a second cooling source introducing portion which takes in water from the outside. The second cooling source introducing portion includes an opening which takes in water. The opening is opened on a rear side of a center of gravity of the entire vehicle body and in a draft portion in an outer surface of the vehicle body.
