<p>1. Change-gear control device comprising a manually actuated lever (1) mounted to be pivotable about a pin (7) which is transverse relative to a longitudinal speed-selecting bar (2) and connected by a ball joint (9) to a speed-changing bar (3), the longitudinal selecting bar (2) being carried by a resilient bearing (11) having a longitudinal axis (X-X) and connected to a fixed support (15), locking means releasable by an axial displacement of a structure (20, 22) connected to the lever (1) being provided for preventing the selection of a speed ratio, characterized in that said locking means comprise a structure (20, 22) mounted to be slidable relative to the lever along the axis of the latter and cooperating with an abutment (33) rigid with a sleeve (27) freely mounted on the selecting bar (2), sets of complementary diametrically opposed abutments being provided between said sleve (27) and the body (13) of the resilient bearing (11).</p> |
