To provide a thrust generator capable of improving stability of rotation motion changing a pitch angle.SOLUTION: A thrust generator comprises: a first motor generating thrust of a rotary wing; a second motor for generating rotation motion for changing a pitch angle of the rotary wing; a first conversion part for converting the rotation motion of the second motor into linear motion; and a second conversion part for converting the linear motion obtained by conversion by the first conversion part into the rotation motion. The second conversion part has a support shaft for transmitting the rotation motion obtained by conversion by the second conversion part to the rotary wing, and an outer peripheral face of the support shaft has a plane which is tilted toward an axial direction of the support shaft toward a direction of the rotary wing.SELECTED DRAWING: Figure 12

    【課題】ピッチ角を変化させる回転運動の安定性を向上させる。【解決手段】推力発生装置は、回転翼の推力を発生させる第1モータと、前記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モータと、前記第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、前記第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、前記第2変換部は、前記第2変換部が変換した回転運動を前記回転翼に伝える支持軸を備え、前記支持軸の外周面は、前記回転翼の方向に向かって前記支持軸の軸方向に傾斜している面を備える。【選択図】 図12
