Ship steering device

A ship steering device comprising:

• an outboard motor attachable to a ship;
• a handle which is mechanically separated from a rudder mechanism of the outboard motor, and which is capable of electrically operating the rudder mechanism;
• a steering angle detecting unit that detects a steering angle of the handle;
• a reaction force motor that generates reaction force torque to be applied to the handle;
• a storing unit that stores a steering characteristics map which associates a basic relation between the steering angle and an aiming steering torque required for the handle;
• and
• a reaction force controller that controls, based on the steering characteristics map, a drive current value which drives the reaction force motor such that the reaction force torque in accordance with the steering angle is obtained,
• wherein the steering characteristics map has characteristics in such a way such that an amount of change in the aiming steering torque relative to the steering angle is smaller in a second steering range where the steering angle is larger than the steering angle in a first steering range than a change amount of the aiming steering torque in the first steering region where the steering angle is set in advance from zero.
