させてなるロータリ一式制御弁。A sleeve valve member is assembled concentrically and relatively rotatably to the outer periphery of a spool valve member that rotates integrally with the input shaft, and a plurality of land portions are provided in the axial direction on the outer periphery of the spool valve member, and each of these land portions. The pressure fluid flowing through the groove between the sleeve valve member and a plurality of lands provided in the axial direction on the inner periphery of the sleeve valve member is controlled by the relative rotational displacement of the two valve members, and A rotary large side of a power steering device configured to control the supply and discharge of pressure fluid - in both valves, the inner end of the output shaft is supported coaxially and relatively rotatably with the input shaft, or is fitted with the inner end of the output shaft. A radial protruding pin is provided at the end of the sleeve valve member, at least two perpendicular split grooves are provided at the protruding end of the protruding pin to provide a radial elastic portion, and the elastic portion is provided at the end of the sleeve valve member. or a pin hole formed in the inner end of the output shaft.
