Abstract

A toothed pinion (1), mounted in a guide body, engages with teeth (3) of a rack (4) longitudinally displaceable in said guide body. A support member (6) is located interposed between the guide body and the rack (4), said support member (6) having a hollow (7) for receiving the portion of the rack bar (4) opposite to said teeth (3). The support member (6) has flexible portions (9', 9') at least partly around and in contact with said rack bar (4) without contacting said guide body, and supported by a control spring (12) to maintain the flexible portions (9', 9') in contact with said rack bar (4) whilst permitting controlled bending in a direction radial to the axis of said rack bar (4).
