To provide a fluid actuator capable of safely driving a drive object.SOLUTION: An air actuator with air as working fluid, comprises: an X-axis pressure sensor that measures air pressures PX+, PX- along one drive shaft that drives a drive object in an X direction; a Y-axis pressure sensor that measures air pressures PY1+, PY1-, PY2+, PY2- along two drive shafts that drive the drive object in a Y direction; and an acceleration detection unit that detects translational and rotational accelerations of a drive object W based on the measured air pressures PX+, PX-, PY1+, PY1-, PY2+, and PY2-.SELECTED DRAWING: Figure 1 【課題】駆動対象を安全に駆動できる流体アクチュエータを提供する。【解決手段】空気を作動流体とするエアアクチュエータは、駆動対象をＸ方向に駆動する１つの駆動軸に沿ったエアの圧力ＰＸ＋、ＰＸ－を測定するＸ軸圧力センサと、駆動対象をＹ方向に駆動する２つの駆動軸に沿ったエアの圧力ＰＹ１＋、ＰＹ１－、ＰＹ２＋、ＰＹ２－を測定するＹ軸圧力センサと、測定されたエアの圧力ＰＸ＋、ＰＸ－、ＰＹ１＋、ＰＹ１－、ＰＹ２＋、ＰＹ２－に基づき、駆動対象Ｗに生じる並進加速度および回転加速度を検知する加速度検知部とを備える。【選択図】図１
