Summary:To provide a thrust generator capable of properly preventing impact to a functional part caused by dust, rain and the like.SOLUTION: A thrust generator comprises: a first motor for 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 rotation motion of the second motor into linear motion; a second conversion part for converting the linear motion obtained by conversion by the first conversion part into the rotation motion; and a hub for supporting the rotary wing and storing at least a part of the second conversion part. The hub comprises: a case having a storage part for storing at least a part of the second conversion part; an inner lid for closing the storage part and being fixed to the case; and an outer lid which is engaged to at least one of the case and the inner lid, and covers the inner lid.SELECTED DRAWING: Figure 13 【課題】機能部品への埃や雨などの影響を適切に防ぐことができる推力発生装置を提供する。【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、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、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、回転翼を支持するとともに、第２変換部の少なくとも一部を収容するハブと、を備える。ハブは、第２変換部の少なくとも一部を収容する収容部を有するケースと、ケースに固定されて収容部を塞ぐ中蓋と、ケースおよび中蓋の少なくとも一方に係止され、中蓋を覆う外蓋と、を備える。【選択図】 図１３
