To provide a propeller device that can be reduced in size and weight and can prevent pitch changing means thereof from acting as air resistance and which can control a posture of a machine body.SOLUTION: A propeller device comprises: a rotating member 1 that is connected to an output shaft of a motor to be rotationally driven; a plurality of vane members 2 attached to the rotating member 1; pitch changing means 3 that rotates the vane members 2 respectively with shafts L2 extending in a longitudinal direction thereof as centers to change pitches of the vane members 2; a linear actuator 4 that actuates the pitch changing means 3; and an activating member 5 that activates the pitch changing means 3 by driving the linear actuator 4. The rotating member 1 has a storage space formed therein, and has the pitch changing means 3 arranged in the storage space.SELECTED DRAWING: Figure 5
【課題】装置の小型軽量化を図ることができるとともに、ピッチ変更手段が空気抵抗になってしまうのを防止することができるプロペラ装置を提供する。また、本発明の装置により、機体の姿勢制御も可能となる。【解決手段】モータMの出力軸と連結されて回転駆動可能な回転部材1と、回転部材1に取り付けられた複数の羽根部材2と、羽根部材2の長手方向に延びる軸L2を中心としてそれぞれ回転させて羽根部材2のピッチを変更するピッチ変更手段3と、ピッチ変更手段3を作動させるリニアアクチュエータ4と、リニアアクチュエータ4の駆動によってピッチ変更手段3を作動させる作動部材5とを具備したプロペラ装置であって、回転部材1は、内部に収容空間が形成されるとともに、当該収容空間にピッチ変更手段3が配設されたものである。【選択図】図5
