A power steering apparatus according to the present invention is constructed to calculate a rate of change of steering speed detected by steering speed detecting means and judge whether the calculated rate of change is smaller than or equal to 0 or not, and reduce a gain of feedback control in comparison with a gain at the time of judgment when it is judged that the rate of change remains smaller than or equal to 0 for a predetermined time period and keep the reduced gain of feedback control until the deviation between target rotational speed and actual rotational speed of an electric motor becomes larger than 0.
