ABSTRACT:
This device comprises a side wall (1) fixed to one of the elements and provided with a toothed ring (12) which is, at rest, engaged with a toothed ring (14) connected to a cup which is axially movable, under the action of a plate (26) carrying balls (46), along a control rod extending axially through the toothed ring (12) of the side wall. The cup (16) is extended by a gear pinion (18) engaged with the teeth of a bar (2) for connection to the second element so that the rotation of the pinion results in the rectilinear displacement of the bar (2).
