摘要： An output shaft and arms are installed inside a cylinder. Pistons that are formed in an arc shape and rotatably connected to the arms slide and are displaced in the circumferential direction of the cylinder inside the cylinder. Inside the cylinder, a first pressure chamber on the arm side and second pressure chambers on the piston head portion side are provided. Third pressure chambers are provided on both sides of the cylinder. A pressure medium is supplied to one of the first pressure chamber and the second pressure chamber and discharged from the other, and the output shaft pivots in a rotational direction. When the pressure medium is supplied to the second pressure chambers, the pressure medium is also supplied to the third pressure chambers.

摘要： A cylinder is installed within a case. An output shaft is installed in a hollow space within the cylinder. A pair of pistons extend in an arc, and is supported so as to be able to slide and be displaced along a circumferential direction of the cylinder within the cylinder. The pair of pistons is able to urge an arm integrated with the output shaft from two sides of the arm. Pressure chambers into which a pressure medium is introduced are defined between the cylinder and each piston in the pair of pistons. The pressure medium is fed to one of the pressure chambers and drained from the other, and thus the arm is displaced, and the output shaft pivots in a rotational direction.
