徴とするロータリーアクチユエータ。 A piston 5 that reciprocates by supplying and discharging pressure is inserted into a cylinder chamber 2 formed in the body 1, and a shaft hole 9 is formed in the piston 5, which is prevented from rotating with respect to the body 1, along the reciprocating direction. The body 1 rotatably supports a rotary shaft 23 which is partially inserted into the shaft hole 9, and screw teeth are formed on the inner diameter surface of the shaft hole 9 and the outer diameter surface of the rotary shaft 23 to mesh with each other. A rotary actuator characterized in that a linear motion of a piston 5 is converted into a rotational motion of a rotating shaft 23, and the rotational motion is outputted to the outside.
