の油圧反力機構。 each rotatably supported within the housing,
Provided between an input shaft and an output shaft that are coaxially connected to each other so as to be relatively rotatable by a predetermined angle, and have a servo valve that is operated based on the relative rotation between them, and that is located on the output shaft side of the input shaft. The housing has a radial protrusion formed at the end thereof, and a storage groove formed at the end of the output shaft on the input shaft side for accommodating the radial protrusion rotatably by a predetermined angle, and is rotatable within the housing. a large-diameter portion that can be fitted to the large-diameter portion; In a hydraulic reaction force mechanism of a power steering device, each of which is provided with a reaction force piston that is pressed by hydraulic pressure, a locking plate formed of an elastic body and whose end can be elastically deformed by a predetermined amount is placed on the outer end side of the cylinder hole. and the rear end of the reaction piston is supplied to the end of the locking plate, so that the elastic force of the locking plate acts when the reaction piston moves forward from the neutral position. The featured hydraulic reaction force mechanism of the power steering device.
