A control device for controlling the variation of the angle of attack of the blades of the anti-torque rotor for an aircraft capable of hovering is described, comprising a control element sliding along a first axis with respect to a shaft of the rotor and rotatable integrally therewith; the control element is operatively connected to a plurality of blades articulated on the shaft in order to vary the angle of attack thereof following a translation of the element itself along the axis; a control rod axially sliding along the axis with respect to the shaft and angularly fixed with respect to the axis; and a rolling bearing interposed between the control rod and the control element, sliding along the axis with respect to the shaft and integrally with the control rod; the control device comprises a threaded element screwed onto the control rod and cooperating with the bearing to constrain it axially with respect to the control rod and a bushing coupled in an angularly and axially fixed manner to the threaded element, and in an angularly fixed manner to the control rod.
