An output shaft that is rotatable around an axis perpendicular to the axis is provided to pass through the cylinder tube, and two pistons are slidably inserted in the cylinder tube so as to face each other with the output shaft in between. A recess is formed in the end surface of the piston facing the output shaft, and the recess is recessed in the direction of both left and right ends of the cylinder tube at the inner diameter part from the skirt portion of each piston, and the recess is recessed in the direction of both left and right ends of the cylinder tube. Protruding arms are provided that enter toward the output shaft, and engagement portions at the distal ends of each arm are engaged with engagement grooves at both ends of a lever that is fitted onto the output shaft and rotates integrally,
A fluid pressure actuator characterized in that an output shaft is configured to reciprocate at an appropriate angle in response to movement of both pistons in opposite directions.
