けたことを特徴とする車両用動力舵取装置。 A valve rotor rotates integrally with an input shaft rotatably supported within the valve housing, and a pinion shaft coaxially and rotatably connected to the input shaft by a predetermined amount rotates integrally with the input shaft. a valve sleeve arranged concentrically on the outer periphery; a torsion bar that interconnects the two shafts to generate relative rotation between the valve rotor and the valve sleeve in accordance with steering torque; and a relative rotation between the valve rotor and the valve sleeve. In a power steering system for a vehicle comprising a rotary valve type control valve equipped with a switching valve mechanism that operates to control the supply and discharge of hydraulic oil to each oil chamber of a power cylinder, the control valve is coaxially connected to the pinion shaft of the control valve. and a second shaft that rotates integrally with the output shaft connected to the output shaft so as to be relatively rotatable by a predetermined amount.
a second valve sleeve that rotates integrally with the pinion shaft and is disposed concentrically around the outer periphery of the second valve rotor, and a second valve sleeve that connects both shafts and has a spring constant smaller than that of the torsion bar. A second torsion bar, a weight provided on the output shaft, and a relative rotation between the second valve rotor and the valve sleeve operate to control supply and discharge of hydraulic oil to each oil chamber of the power cylinder. A sub-control valve having a second switching valve mechanism is provided, and when the vehicle speed reaches a predetermined value, the switching operation is performed to switch the connection of the oil supply line from the pressure oil source from the control valve to the sub-control valve. A vehicle power steering device characterized by being provided with a switching valve.
