PROBLEM TO BE SOLVED: To provide a steering device which can move a ship in the transverse direction while maintaining the azimuth without reducing the moving speed in the transverse direction by the output of a bow thruster. SOLUTION: This steering device comprising a propulsion propeller for obtaining the propulsion force in the longitudinal direction of a hull, a rudder and the bow thruster for obtaining the propulsion force in the transverse direction of the hull, comprises an operating means which enables the heeling operation including the heel in the longitudinal direction and the transverse direction of the full from the upright stop position and a controller for outputting the signal to control the movement of the propulsion propeller and the bow thruster based on the setting by the operating means. The controller controls the blade angle of the bow thruster so as to obtain the maximum value of the propulsion force in the transverse direction outputted thereby in the setting that the azimuth of the bull is maintained, and the hull is moved in the transverse direction, and the controller also controls the blade angle of the propulsion propeller and the angle of the rudder are corrected in the azimuth deviation to the hull so as to obtain the turning moment required for maintaining the azimuth.
