PROBLEM TO BE SOLVED: To provide a power transmission device for a flying vehicle capable of providing reductions in size, the number of parts, cost, and operation noise, and having a function of inversely rotating a first propeller and a second propeller. SOLUTION: In this power transmission device for the flying vehicle which is constituted so as to fly by a rotational force of the first propeller and the second propeller rotating inversely to each other, a planetary type power transmission mechanism is constituted of an inner wheel which is fixed onto an outer periphery side of an input shaft, an outer wheel which is fixed onto an inner periphery side of the second propeller, an annular carrier which is fixed at a case member, and a plurality of rotating bodies which are supported at the carrier so as to rotate freely along a circumferential direction. The first propeller and the second propeller are rotated inversely to each other by the planetary type power transmission mechanism, and a bearing mechanism in which the input shaft and the inner wheel of the planetary type power transmission mechanism are supported to the case member through the rotating bodies and the carrier so as to rotate freely is constituted.
