油圧切換弁とを備えたことを特徴とする動力舵取装置。The power source is equipped with a rotary type control valve that switches and operates based on the input rotation from 1 dollar to 200 degrees, and selectively supplies pressurized oil to the output drive unit connected to the wheels via the control valve. In the steering device, a long groove is formed in the circumferential direction spanning the spool and sleeve of the control valve, and reaction chips are slidably housed at both ends of the long tread to form a reaction chamber number. A vehicle speed detection means for detecting a high speed range is provided, and a hydraulic switching valve is provided which switches in the high speed range based on a signal from the detection means and directs pressure oil from the pop port to the reaction force chamber described above. A power steering device characterized by:
