とする操舵用アクチユエータ。[Claims for Utility Model Registration] A pair of free pistons are provided in the cylinder, and a neutral holding mechanism is provided between these free pistons with an elastic body interposed between them, and the hydraulic pressure supplied from the pump is used to control the front or rear wheels. In a steering device that is connected to a power cylinder that steers at least one of the two free pistons, a hydraulic pressure of a predetermined pressure or higher supplied from the pump is applied to both outer end surfaces of the two free pistons, and the movement of each free piston is controlled. A steering actuator characterized by having a movement amount limiting means for restricting the amount of movement by a certain amount.
