PROBLEM TO BE SOLVED: To provide a hydraulic actuator which can suppress interference between a flap and a spoiler.SOLUTION: A hydraulic actuator for driving a spoiler is equipped with a piston rod 30 for driving the spoiler, and a stopper piston 40 as movement restriction means which can restrict movement of a piston rod 30 in a direction in which the spoiler approaches the flap in an overlapping region in which a driving range of the flap and a driving range of the spoiler are overlapped with each other and at a neutral position which is a position of the spoiler when an aircraft is cruised.SELECTED DRAWING: Figure 1

    【課題】フラップとスポイラとの干渉を抑制することができる油圧アクチュエータを提供する。【解決手段】スポイラを駆動させる油圧アクチュエータは、スポイラを駆動させるためのピストンロッド30と、フラップの駆動範囲とスポイラの駆動範囲とが重複する重複領域、および、航空機が巡航するときのスポイラの位置である中立位置において、スポイラがフラップに接近する方向へのピストンロッド30の移動を制限可能な移動制限手段としてのストッパピストン40を備える。【選択図】図1
