。 a case, an output shaft whose outer end protrudes outward through the end wall of the case in a sealed and slidable manner; and an outer end arranged coaxially with the output shaft and movable relative to the inner end in the axial direction. is wedged into a rotating shaft, and the rotary shaft is slidably and sealably fitted between the outer circumferential surface of the rotating shaft and the inner circumferential surface of the case, and is wedged to the rotating shaft so as to be relatively displaceable in the axial direction. An annular piston spirally engaged with the case, and a first piston limited to the outside of a flange provided on the inner outer periphery of the output shaft.
a second fluid pressure chamber limited to the inside of the flange, a third fluid pressure chamber limited to the outside of the outer end surface of the piston, and a third fluid pressure chamber limited to the inside of the inner end surface of the piston. A torque actuator comprising a fourth fluid pressure chamber.
