とを特徴とする電動機式動力舵取装置。[Claims for Utility Model Registration] A steering mechanism that transmits steering force to steered wheels, a power assist mechanism capable of applying a steering assist force by an electric motor to this steering mechanism, and a control of the steering assist force by this power assist mechanism. An electric motor type power steering device having an assist control unit, the assist control unit having a return assist force that causes the assist control unit to apply a return assist force to the steering mechanism when returning the steering mechanism to a neutral position corresponding to a straight-ahead state. It comprises a control means, temporary stop state detection means for detecting whether or not the vehicle is in a temporary stop state, and when the temporary stop state detection means detects that the vehicle is in a temporary stop state, the returning assisting force is applied. 1. An electric motor type power steering device comprising a return assist inhibiting means for prohibiting the control means from applying a return assisting force.
