To reduce weight of a motor which generates thrust while receiving thrust of a rotary vane.SOLUTION: A thrust generator comprises: a first motor that generates thrust of a rotary vane; a second motor that generates rotary motion for varying a pitch angle of the rotary vane; a first converting part that converts the rotary motion of the second motor to linear motion; and a second converting part that converts the linear motion converted by the first converting part to rotary motion. The first motor comprises: a rotor; a stator; a stator case that can store the stator, in a position facing the rotor; and a bearing that bears a rotor shaft of the rotor freely rotatably. The stator case comprises a first load receiving part that receives an axial load acting on the bearing. Load bearing of the first load receiving part differs depending on a direction of the axial load.SELECTED DRAWING: Figure 12

    【課題】回転翼の推力を受け止めつつ、推力を発生させるモータを軽量化する。【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1モータは、ロータと、ステータと、前記ロータと対向する位置に前記ステータを収容可能なステータケースと、前記ロータのロータ軸を回転自在に支持する軸受とを備え、前記ステータケースは、前記軸受にかかるアキシアル荷重を受ける第1荷重受部を備え、前記第1荷重受部は、前記アキシアル荷重の方向に応じて耐荷重が異なる。【選択図】 図12
