To suppress deterioration in variable accuracy of pitch angles on the basis of rotational motion converted from linear motion.SOLUTION: A thrust generating device includes a first conversion part which converts rotational motion of a second motor for generating the rotational motion for changing pitch angles of a rotor to linear motion, and a second conversion part which converts the linear motion converted by the first conversion part to the rotational motion. The second conversion part includes a linear motion body which can linearly move in accordance with the linear motion converted by the first conversion part, a rack-and-pinion which converts the linear motion converted by the first conversion part to the rotational motion, a case which stores the linear motion body and the rack-and-pinion, and an energizing member which generates pressing force in a direction for pressing a rack of the rack-and-pinion against a pinion. The rack is supported by the linear motion body, and the pinion is supported by a support shaft side of the rotor.SELECTED DRAWING: Figure 12

    【課題】直線運動から変換された回転運動に基づくピッチ角の可変精度の低下を抑制する。【解決手段】推力発生装置は、回転翼のピッチ角を変化させる回転運動を発生させる第2モータの回転運動を直線運動に変換する第1変換部と、第1変換部で変換された直線運動を回転運動に変換する第2変換部とを備え、第2変換部は、第1変換部で変換された直線運動に従って直線運動可能な直動体と、第1変換部で変換された直線運動を回転運動に変換するラックアンドピニオンと、直動体およびラックアンドピニオンを収容するケースと、前記ラックアンドピニオンのラックをピニオンに押し付ける方向に押付力を発生する付勢部材とを備え、前記ラックは、前記直動体で支持され、前記ピニオンは、前記回転翼の支持軸側で支持される。【選択図】 図12
