A power steering apparatus includes: a steering mechanism connected with a steering wheel; a transmitting mechanism connecting the steering mechanism and a steered wheels; a motor arranged to drive the transmitting mechanism based on a torque inputted to the steering mechanism to provide a steering assist force to the steered wheels; a motor control section configured to output a drive signal to the motor in accordance with the steering assist force; a motor reverse rotation judging section configured to judge a reverse rotation state of the motor when an actual rotation direction of the motor does not correspond to a direction in which the motor is rotated by the driving signal from the motor control section; and a damping torque adding section configured to damp a torque generated in the motor when the motor reverse rotation judging section determines the reverse rotation state of the motor.
