Claims

[Claims for Utility Model Registration] (1) A cylinder chamber is formed by the tube and the covers attached to both ends of the tube, and a piston for linear reciprocating movement is housed in the cylinder chamber, and the piston is provided with a rotation prevention means. Therefore, it is locked in the rotational direction and is mounted so as to be slidable only in the axial direction, and the inner chamber formed with a hollow interior has a fixed shoe and an output shaft protruding from both ends to allow reciprocating rotational movement. A swing vane is housed therein, and both ends of the output shaft, each protruding from the piston, are pivotally supported in an airtight manner while penetrating the cover, and each cover is supplied with pressurized fluid for linear reciprocating motion into the piston chamber. A pair of hollow guide rods protruding from the piston side and penetrating the cover are used for the rotation prevention means, and the guide rods are reciprocated into the vane chamber formed by the inner chamber of the piston. A composite actuator characterized by having a flow path for supplying and discharging pressure fluid for motion. (2) A cylinder chamber is formed by the tube and the covers attached to both ends of the tube, and a piston for linear reciprocating movement is housed in the cylinder chamber, and the piston is prevented from rotating in the direction of rotation by a rotation prevention means. A fixed shoe and a swinging vane having output shafts protruding from both ends for reciprocating rotation are housed in an inner chamber formed with a hollow interior. Both ends of the output shafts protruding from the pistons are hermetically supported while passing through covers, and each cover is provided with a flow path for supplying and discharging pressure fluid for linear reciprocating motion into the piston chamber. . A composite actuator, wherein a flow path is formed in the output shaft for supplying and discharging pressure fluid for reciprocating rotational movement into a vane chamber formed by an inner chamber of the piston. (3) A sleeve that rotatably holds the output shaft and is fixed to the cover is wrapped around the outer periphery of at least one end of the output shaft protruding from the cover, and the sleeve is wrapped around the outer circumference of at least one end of the output shaft. 2. The composite actuator according to claim 2, wherein a passage is formed in the shaft and communicates with a passage for supplying and discharging pressure fluid for reciprocating rotational motion.
