In the hydraulic rotation servo mechanism, the hydraulic control section is constituted by a rotary valve that switches to the hydraulic pressure supply side by relative rotational displacement of input and output shafts, and the hydraulic actuator section includes the rotary valve, and It has a rotor in which an open end of a valve oil passage is formed on its outer circumferential surface, and a large number of vanes that are provided in a housing and are pressed against the outer circumferential surface of the rotor. A hydraulic rotation servo mechanism comprising a vane servo actuator that directly assists the rotational force of a rotor by supplying pressure oil.
