Abstract
A power steering device is mounted on a vehicle and includes a variable transmission ratio mechanism, a torque applying unit, and an applied friction torque changing unit. The torque applying unit sets an applied friction torque applied to the steering wheel and performs a control of applying the applied friction torque to the steering wheel. The applied friction torque changing unit changes the applied friction torque based on the transmission ratio of the variable transmission ratio mechanism.
