To provide an amphibian vehicle capable of efficiently converting rotation energy of a rotor into thrust.SOLUTION: An amphibian vehicle 100 comprises: a support; a rotor supported so as to be rotatable about a first axis X1 with respect to the support; a plurality of blade bodies 7 each supported so as to be rotatable about a second axis X2 with respect to the support; a wheel 2 rotated integrally with the rotor; a vehicle body 1 that supports the support; and an interlock mechanism for interlocking the rotation of the rotor about the first axis X1 with the rotation of each blade body 7 about the second axis X2. The interlock mechanism is configured to set the rotating direction of the rotor about the first axis X1 and the rotating direction of the blade body 7 about the second axis X2 opposite to each other, and the rotational period of the blade body 7 about the second axis X2 N times (N is natural number) as large as that of the rotor about the first axis X1. The blade body 7 is provided with a pressure reception surface which receives a pressure of water. The interlock mechanism is configured to direct the pressure reception surface of the blade body 7 positioned at the lowest point of a rotation locus about the first axis X1 to a rear side T2.SELECTED DRAWING: Figure 1
