Abstract
A plurality of blade shafts spline-connected to bosses of a plurality of propeller blades are rotatably carried on a propeller boss parallel to the axis of the boss, the propeller blades being rotated so as to increase the propeller-diameter D according to an increase in the centrifugal force, and all the blade shafts are mutually connected through a synchronizer including cranks integrally continuously provided on the blade shafts and a single common synchronizing ring. With this arrangement, it is possible to always equally control opening angles of all the propeller blades despite any partial conditional change.
