    Abstract: An engine device for an unmanned flying apparatus that provides good weight balance for the flying apparatus; cancels the gyroscopic effect; and has auto rotating propellers.
    The engine device includes a first cylinder and a second cylinder arranged horizontally and opposed to each other, and pistons within the cylinders advance and retract in opposite directions to each other; a first crankshaft and a second crankshaft arranged in the vertical direction, driven by the first cylinder and the second cylinder, respectively, and rotate in opposite directions; a first centrifugal clutch and a second centrifugal clutch rotate in opposite directions to each other; a final drive shaft transmitting rotational force to a gear mechanism comprising orthogonal transform gears, to rotate a propeller shaft; a one-way clutch arranged between



    the first crankshaft, the second crankshaft and
    the final drive shaft, and driven by both the first crankshaft and the second crankshaft.

    Abstract: A flight device in which a mechanism for transmitting power is simplified is provided. The flight device 10 includes an airframe 19, main rotors 14, an engine 30, and power transmission shafts 25. The main rotors 14 are rotated to generate drive force that causes the airframe 19 to lift. The engine 30 includes crankshafts. The power transmission shafts 25 are connected to the crankshafts. Moreover, the engine 30 rotates the main rotors 14 via the power transmission shafts 25. The power transmission shafts 25 are tilted with respect to a second direction D2.
