成されていることを特徴とする動力舵取装置。A control valve spool is connected via a pin to the ring gear of the planetary gear, which has a planet gear on the input side and a sun gear on the output side, and pressurized oil is supplied to the power cylinder via the control valve, which switches based on the input rotation of the handle. In a power steering device that selectively sends reaction force chambers at both ends of the spool, a switching valve that switches in response to vehicle speed is provided, and the switching valve switches between the two reaction chambers in a low speed range. A power steering device characterized in that it is configured to introduce pressure oil from an operating port into reaction force chambers that communicate with each other and oppose displacement of a spool in a high-speed range.
