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 corresponding to the above is controlled by the relative rotational displacement of both the valve members, and the power cylinder In a rotary set control valve for a power steering device, which controls the supply and discharge of pressure fluid to and from the input shaft, the rotary control valve is fitted to or on the inner end of an output shaft coaxially and rotatably supported with respect to the input shaft. A radial protruding pin is provided at the end of the sleeve valve member, and the protruding pin is engaged with the end of the sleeve valve member or the inner end of the output shaft via an elastic member. A rotary complete control valve characterized by absorbing vibrations.
