摘要

PROBLEM TO BE SOLVED: To provide a rudder with a rudder valve which can be easily manufactured, a ship, the rudder valve, and a method for manufacturing the rudder with the rudder valve.;SOLUTION: The rudder 3 with the rudder valve includes: a cylindrical rudder valve 5 with at least axial one end closed; and a rudder 4 for controlling a propulsion direction. An opening part 41 having a shape corresponding to the outer shape of the rudder valve 5 is formed at the position opposite a propulsion propeller 2 in the rudder 4, and the rudder valve 5 is joined to the opening part 41 with one end facing the propulsion propeller 2. Thus, the rudder valve 5 does not need to be molded according to the rudder 4, and the shape of the rudder valve 5 can be simplified.;COPYRIGHT: (C)2012,JPO&INPIT
