    摘要： [PROBLEM TO BE SOLVED
    The present invention provides an engine device for an unmanned flying apparatus that provides good weight balance for the flying apparatus; can cancel the gyroscopic effect; and has propellers that can auto rotate.
    [SOLUTION]
    The engine device of the present invention comprises: 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 to each other; 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
    (1) the first crankshaft, the second crankshaft and
    (2) the final drive shaft, and driven by both of the first crankshaft and the second crankshaft.

    摘要： A torque limiting device (24) comprises an input shaft (56), an output shaft (50) and a machined torsion spring (80) having a first end (82) and a second end (84). The first end (82) and the second end (84) of the torsion spring (80) are coupled to the both the input shaft (56) and the output shaft (50), whereby torque is transmitted between the input shaft (56) and output shaft (50) via the torsion spring (80). The couplings between the torsion spring (80) and the input shaft (56) and the output shaft (50) permit limited relative rotation between the input shaft (56) and the output shaft 50). The device further comprises a jamming mechanism (78) operable in response to relative rotation between the input shaft (56) and output shaft (50) to stop rotation of both the input shaft (56) and the output shaft (50).
