PROBLEM TO BE SOLVED: To provide a mounting means for a stator fin for positioning the stator fin to straighten a rotational flow generated by a screw propeller for propelling a ship. SOLUTION: The stator fin is mounted on the mounting part of a rudder. This mounting means is imparted to position and fix the stator fin at the mounting part so that an axis of the screw propeller and an axis of the stator fin coincide with each other. For instance, a gap is formed between the stator fin and the mounting part projecting from the rudder, and an annular element is welded between the stator fin and the mounting part to hold the stator fin at a proper position by regulating the amount of the gap.
