A power steering device sets an applied friction torque applied to a steering wheel based on a real steering angle and a target steering angle, and performs a control of applying the applied friction torque to the steering wheel. An applied friction torque changing unit changes the applied friction torque, which is calculated from the real steering angle and the target steering angle, when the vehicle reverses. Concretely, the unit changes the applied friction torque to a smaller value when the vehicle reverses than that when the vehicle advances. Thereby, it is possible to decrease the applied friction torque properly when the vehicle reverses, and it become possible to improve the maneuverability of the steering wheel.
