PROBLEM TO BE SOLVED: To provide a fluid actuator capable of realizing a droop function through a simple mechanical structure, suppressing reduction in aerodynamic characteristics of a blade, reliably suppressing generation of contact between a first moving blade and a second moving blade, and preventing a fluctuation center position of a cylinder from being displaced.SOLUTION: The fluid actuator includes a cylinder 11, a piston 12, a rod 13, an output part 14, a link mechanism 15, an arm member 16, a stopper member 17, and a stopper driving part 18. The link mechanism 15 is displaced in association with movement of a second moving blade 103. The arm member 16 is displaced in association with the displacement of the link mechanism 15. The stopper driving part 18 is rotated in association with the displacement of the arm member 16. The stopper driving part 18 drives the stopper member 17 so as to change a position of the stopper member 17 in the cylinder 11 by rotation in accordance with the displacement of the arm member 16. |
