The invention relates to a device, of the type comprising a toothed wheel (3) and a rack (7) activated by a screw (6), for the selective adjustment of the angular inclination of the arms of a blind with respect to a support (5) on which the ends of the said arms remain articulated. According to the invention, the screw (6)/rack (7) mechanism and the elements (8) for blocking the axial displacement of the end of the said control screw remain housed entirely inside a cavity (17) which is tangential to the toothed part of the disc-shaped pieces (3), the said screw (6) having, at the other end, a widened head provided with a seat (6b) intended to be operated by a suitable key which is introduced through the opening (18). <IMAGE>
