An electric power steering apparatus wherein desired steering assist force can be stably provided by positively precluding actuation of an electric motor while it is rotating in a reverse direction so as to prevent demagnetization of the electric motor. This apparatus includes motor reverse rotation detecting means for detecting whether or not the electric motor is rotating in the reverse direction and motor actuation control means for actuating the electric motor when a condition for actuating the electric motor is fulfilled and on condition that the electric motor is not rotating in the reverse direction.
