。A bell crank pivotally attached to a knob near the blade shaft on the axis in the aircraft's direction perpendicular to the pitch conversion axis of each blade, a weight part provided at the tip of the bell crank on the side away from the blade, and a blade shaft. It consists of an eccentric pin that protrudes eccentrically from the end face with respect to the pitch conversion axis, and a rod that connects the end of the bell crank near the blade and the eccentric pin, and reduces the centrifugal force that the weight receives when the propeller rotates. , a counterweight mechanism for a variable pitch propeller, which converts the centrifugal torsional moment received by each blade into rotational force about a pitch conversion axis in the opposite direction.
