Zusammenfassung:	PROBLEM TO BE SOLVED: To rotate upper and lower rotary shafts in the directions opposite to each other by providing upper and lower bevel gears and a UAV power device sub-system for connecting the torque to a counter-rotating rotor with a mechanically engageable input gear. SOLUTION: A single-stage transmission sub-system 120 has an input pinion gear 122. The input pinion gear 122 comprises a spline end 124, a bearing 126 for mounting the input pinion gear 122 rotatably connected to a transmission housing 140, and upper and lower spiral bevel gears 128, 130. The upper and lower spiral bevel gears 128, 130 are respectively provided with integrally formed upper and lower rotor shafts 128R, 130R, which dispenses with an independent rotor shaft connecting means. Upper and lower multiblade rotors are respectively combined with the rotor shafts 128R, 130R to be fixed.
