Claims

[Scope of utility model registration request]

In a reaction rudder placed behind the screw propeller of a ship, twists in opposite directions are applied above and below the center height of the propeller shaft so that the leading edge of the rudder points in the opposite direction to the rotational direction of the screw propeller. A reaction rudder characterized in that the amount of twist is set larger at the leading edge portion above the center height position of the propeller shaft than at the leading edge portion below.
