PROBLEM TO BE SOLVED: To provide a steering device for navigation imparting no sense of incongruity to a driver without generating response delay in steering. SOLUTION: This steering device is provided with a steering angle detecting device 15 for detecting a steering angle of a steering member 14, a reaction actuator 9 for imparting steering reaction to the steering member 14 based on the detected steering angle, steering mechanisms 3 and 30 mechanically separated from the steering member 14 to turn a hull 8, and a turning actuator 11 for driving the steering mechanisms 3 and 30 according to the steering angle detected by the steering angle detecting device 15. The steering device is provided with a steering angular speed arithmetic means 16 for calculating the steering angular speed based on the steering angle detected by the steering angle detecting device 15 and an axial force detecting device 46 for detecting axial force of turning directions of the steering mechanisms 3 and 30. The reaction actuator 9 is constituted to impart the steering reaction to the steering member 14 based on the steering angle, the calculated steering angular speed and the detected axial force.
