Pitch changing device and flight device using the same

摘要

PROBLEM TO BE SOLVED: To provide a pitch change device which has a simple structure, is small, and enables easy improvement of the accuracy, and to provide a flight device using the pitch change device.SOLUTION: A pitch of a propeller 16 is changed by a force generated by a servo motor 21. A rotation force of the servo motor 21 is transmitted to the propeller 16 through a lever member 22, a link member 23, and a change member 24 to change the pitch of the propeller 16. In this way, the rotation force of the servo motor 21 is transmitted to the propeller 16 with a simple structure comprising the lever member 22, the link member 23, and the change member 24.SELECTED DRAWING: Figure 1
