<p>The device (51) has a driving unit (54) associated to a gear lever for passage of a forward gear, where the driving unit drives an axle (26) carrying a shift fork (24) of the forward gear in a position. A conveying unit conveys the driving unit into another position after the selection of the forward gear for the passage of a reverse gear without driving the axle of the fork. The forward and reverse gears are symmetrically placed with respect to a position of dead center in a transverse passageway.</p> |
