ステアリング装置。 A power cylinder configured to have two chambers defined by a piston and boosts steering output, a gear pump, and a motor that drives the gear pump;
and two oil flow ports of the gear pump,
The two chambers of the power cylinder are communicated with each other, and a path connecting the two chambers of the power cylinder is filled with oil through a gear pump, while the rotational torque, direction, and speed of the steering shaft are controlled respectively by the operation of the steering wheel. and controlling the rotational speed of the gear pump driving motor based on the signals from the rotational torque detection means and the rotational speed detection means so that the pump discharge amount corresponds to the steering input and steering speed of the steering wheel. A power steering device comprising: control means for controlling rotational direction switching of a gear pump drive motor according to a steering direction of a steering wheel based on a signal from the rotational direction detection means.
