A device for windmill orientation to wind has working wheel with blades of propeller type, support mast to which lower part of disk or cylindrical type is immovably attached, near to it similar upper part of disk or cylindrical type is placed, this is immovably attached to windmill itself. Each of parts is placed in such way that through its center of symmetry axis of symmetry of rotation of windmill goes at change of direction of wind, and the upper part has possibility to rotate on axis of rotation of windmill at change of direction of wind as well, together with windmill. At the upper or lower part electromechanical device of fixation of windmill position with respect to another similar part is placed, and at least one indicator of position of one of parts of disc or cylindrical type with respect to another similar part. Besides that appliance for windmill orientation to wind has unit for retardation of windmill turn to wind.
