SHIP RUDDER AND SHIP HAVING THE SAME

摘要

PURPOSE: A rudder and a ship with the same are provided to improve the steering performance of a rudder and to simplify the size and structure of a link device without additional driving part. CONSTITUTION: A rudder for a ship comprises a rudder blade(20), a flap part(30), a first gear part(40), a second gear part(50), a first link rod(60). The first flap part is hinge-coupled to the rear end of the rudder blade. The first gear part is supported on a hull and has a backwardly protruded circular arc shape. The second gear part is rotatably coupled at the top of the rudder blade and is gear-coupled to the first gear part. One end of the first link rod is connected to the second gear part and the other end thereof is coupled to the flap part so that the flap part can be rotated on the rudder blade according to the rotation of the rudder blade.
