Document Type and Number:
Japanese Patent JP7476832
Kind Code:
B2
Abstract:
To improve commonization efficiency of a part of a thrust generator in a flight device having the thrust generator for generating rotation torque in a different direction.SOLUTION: In a flight device having a plurality of thrust generators for generating thrust by rotating a rotary blade around a motor rotary shaft, the respective thrust generators have the rotary blade, a grip for holding the rotary blade, a motor, a hub for rotating together with the motor and a pitch angle change mechanism for changing a pitch angle of the rotary blade, and the pitch angle change mechanism has a direct-acting body linearly movable in a rotary shaft direction, a rack installed in the direct-acting body and a pinion for meshing with the rack, and the pinion is installed in the grip, and the rack of one thrust generator among the plurality of thrust generators, is positioned on one side when viewed from the center of the pinion, and the rack of the other thrust generator is positioned on an opposite side of one side of the surface when viewed from the center of the pinion.SELECTED DRAWING: Figure 16A
