To provide a thrust generator capable of properly preventing impact to a functional part caused by dust and 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 a 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 which stores at least the part of the second conversion part; an inner lid which is fixed to the case by a screw member for closing the storage part; and an outer lid which covers the inner lid, and holds the screw member for preventing falling of the screw member.SELECTED DRAWING: Figure 14
【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、ネジ部材によってケースに固定されて収容部を塞ぐ中蓋と、中蓋を覆い、ネジ部材を抜け止め保持する外蓋と、を備える。【選択図】 図14
