This device comprising a column support structure, connected to the rest of the vehicle and comprising two side plates between which is arranged the column and mechanisms for locking the column, which mechanisms comprise a tie rod (20) extending between the side plates, bearing against one of the side plates and connected to locking elements comprising a stop component (24), an intermediate support component (25) and an operating component (26) arranged between the stop component and the intermediate support component, connected to an operating lever (27) and movable in rotation in a plane perpendicular to the tie rod, one of the facing surfaces of the operating component (26) and of the intermediate support component (25) or of the stop component (24) comprising at least one projecting part (30, 31) adapted to cooperate with a ramp (28, 29) of the other, so as to separate these two surfaces from one another and hence the corresponding locking elements so as to bring the side plates together in order to lock the column, is characterized in that the projecting part comprises a rolling bearing component connected to the corresponding locking element.
