To provide a thrust generator with high reliability.SOLUTION: A thrust generator comprises: a thrust generating motor that generates thrust by rotating a plurality of rotors; a plurality of pitch angle changing motors that changes pitch angles of the rotors; and a plurality of rotation transmission parts that are connected respectively to the plurality of pitch angle changing motors; a first motion conversion part; and a second motion conversion part. A motion conversion mechanism of the first motion conversion part is connected to the plurality of rotation transmission parts and a single linear motion shaft, and converts rotation of at least one of the rotation transmission parts into a linear motion of the linear motion shaft. The second motion conversion part converts the linear motion of the linear motion shaft into a rotary motion to change the pitch angle of the rotor.SELECTED DRAWING: Figure 7

    【課題】高い信頼性を有する推力発生装置を提供する。【解決手段】推力発生装置は、複数の回転翼を回転させて推力を発生させる推力発生モータと、回転翼のピッチ角を変更する複数のピッチ角変更モータと、複数のピッチ角変更モータにそれぞれ連結された複数の回転伝達部と、第1の運動変換部と、第2の運動変換部を備える。第1の運動変換部の運動変換機構は、複数の回転伝達部と単一の直動軸に連結されており、少なくとも1つの回転伝達部の回転を直動軸の直線運動に変換する。第2の運動変換部は、直動軸の直線運動を回転運動に変換して、回転翼のピッチ角を変更する。【選択図】図7
