Abstract:
A variable pitch mechanism for a helicopter is configured to have a simple configuration with a small number of members, and to be capable of precisely controlling a pitch angle of blades without accurate adjustment. A pitch plate  16  and a pitch plate boss  17  are slidably mounted on an outer periphery of a main mast  61 , and an output shaft of a servomotor  19  is directly connected to a pitch lever  18  that vertically moves the pitch plate boss  17 . By actuating the servomotor  19  and rotating the pitch lever  18 , the pitch plate boss  17  and the pitch plate  16  are displaced upward or downward along the main mast  61 , thereby tilting blade holders  13, 13  connected to the pitch plate  16  and changing a pitch angle of the blades  14.

Claim (Index 4):
A helicopter for flying in an unmanned manner or a manned manner by remote control or autonomous control, the helicopter comprising the rotor head according to  claim 1 .
