るロータリーアクチユエータ。 A piston is slidably inserted into a cylindrical cylinder body along the axis of the cylinder body, and is engaged with an engaged portion or a spiral guide portion formed on a peripheral wall of the piston. , an output shaft having a spiral guide portion or an engaged portion that is relatively slidable along the engaged portion or the guide portion is rotated about an axis parallel to the axis of the cylinder body; The piston is reciprocated by the fluid supplied inside the cylinder body, and the guide portion or the engaged portion of the output shaft is guided along the engaged portion or the guide portion of the piston. In the rotary actuator in which the output shaft is rotationally driven around the axis of the output shaft, the inner circumferential surface of the cylinder body and the piston in sliding contact with the inner circumferential surface of the cylinder body. A rotary actuator characterized in that the cross-sections of the portions of the outer circumferential surfaces that slide into contact with each other are non-circular so that the piston does not rotate relative to the cylinder body.
