ことを特徴とする動力舵取装置。A pinion is formed on the input shaft on the handle side, and a rack that meshes with this pinion is linked to the steering link of the wheel, and the input shaft is supported so that it can be displaced within a small range in the direction of movement of the rack. A rack-and-pinion type power steering device, which is provided with means for transmitting the displacement of the control valve to the control valve, and in which a power cylinder that responds to pressure oil selectively supplied as the control valve is switched is linked to the rack. A reaction force chamber is formed at each end of the spool of the control valve, and a switching valve is provided to selectively guide hydraulic pressure into the reaction chamber, and this switching valve is switched and operated by a signal from the vehicle speed detection means. A power rudder characterized in that the four reaction force chambers are connected at least in a low vehicle speed range, and the high hydraulic pressure sent to the power cylinder is guided to the reaction force chamber facing the control valve switching direction in a high vehicle speed range. removal device.
