Abstract:
An electromechanical actuator is provided with a power disconnection mechanism including a case portion, inner shaft portion, supporting portions, and connecting members. The case portion is fixed to an electric motor. The inner shaft portion within the case portion is fixed to a screw portion. The supporting portions are installed so as to support a load parallel to the axial direction between the case portion and the inner shaft portion, inserted into the inner shaft portion, and slidable along axial grooves and circumferential grooves with respect to the case portion. The connecting members break connection between the case portion and the inner shaft portion and disconnect transmission of power when torque of a prescribed amount or larger acts.
