とを特徴とした動力舵取装置。[Scope of Claim for Utility Model Registration] A steering mechanism for steering; a power assist mechanism capable of applying a power-assisted return force to the steering mechanism when returning the steering mechanism to a neutral position corresponding to the straight-ahead state of the vehicle; In the power steering device including a return assist control section that controls a return assist force of the power assist mechanism, the return assist control section is configured to determine a return speed target value that determines a target value of the return speed of the power assist mechanism. a steering state determining means for determining a predetermined steering state for causing the power assist mechanism to perform a return drive; return assist force increase control means for gradually increasing the return assist force until the speed reaches the return speed target value; a return assist force holding control means that holds the return assist force at the value at the time of arrival until the steering angle position is restored; and a return assist force holding control means that gradually lowers the return assist force when the steering mechanism reaches a predetermined steering angle. 1. A power steering device comprising return assist force drop control means for restoring the mechanism to a neutral position.
