The invention concerns an electromechanical actuator comprising at least an electric motor ( 1 ), as well as coupling ( 4 ) and gear reduction ( 4 ) means, which drive an output shaft ( 11 ). The invention is characterized in that the coupling and gear reduction means mesh with a crank plate ( 7 ) designed to be driven in rotation with an angular travel limited by two stops, a small connecting rod ( 9 ) being articulated to one end on a crank pin ( 8 ) of said crank plate and being articulated at its other end on a long connecting rod ( 10 ) which is itself integral with the output shaft, the two ends of said long connecting rod being respectively guided in displacement each along a guide, and the displacement angle between said two stops is more than 180°, the movements of the rod being structurally locked in case of overriding, the crank plate being immediately proximate to one of its travel limit stops.
