とを備えたことを特徴とする可変ピッチプロペラ。A blade connected to the propulsion shaft and driven to rotate; a crank pin ring provided at the base end of the blade to rotate the blade in a direction intersecting with the rotation drive direction to change its pitch; and a crank pin ring screwed to the propulsion shaft. a feed screw body which is fitted together and rotationally driven in synchronization; and a feed screw body which is detachably provided on the feed screw body and applies a brake to the rotation of the feed screw body to generate a rotation difference with the propulsion shaft. A variable pitch propeller comprising: a braking means for reciprocating the crank pin ring in its axial direction; and a crosshead for rotationally driving the crank pin ring following the reciprocating movement of the feed screw body.
