Abstract
A hub (10) of a steering wheel and a terminal element (20) of a shaft are adapted to be interconnected by a wedging locking device (100) employing male and female cones and an axial clamping mechanism (200) employing a screw and a nut. A fine adjustment device includes at least one couple of pair of a groove (31) and a tongue (32) which extend longitudinally, are cooperative and complementary and adapted to be engaged one inside the other with confronting radial faces (301, 302) spaced apart from each other by a predetermined clearance, a toothed sector (33) and a confronting cavity (34) adapted to act as a semi-bearing for a gear pinion (35) capable of meshing with the toothed sector.
