The present invention provides a power steering device, concerning compensation of a steering assist force loss caused by friction in a steering mechanism, when a friction correction value for the compensation is computed, static friction and dynamic friction are distinguished in an electronic control unit (6), and the computation is performed on the basis of a combination of respectively corresponding static friction correction value (Sf) and dynamic friction correction value (Kf), whereby an appropriate friction loss compensation can be provided in accordance with the type of friction.
