A column-mounted gear selector mechanism comprises a gear shift lever assembly including a control arm integrally connected to a shift tube and projecting radially outwards therefrom to have a free end, a bell crank installed in the control arm and having a first lever arm pivotally connected to a compression rod, a knob pivotally installed on the free end of the control arm and formed with an elongated guide opening, a guide pin movable in the guide opening, and a connecting rod interconnecting the guide pin and a second lever arm of the bell crank such that turns of the knob in the opposite direction about the axis thereof are transmitted through the connecting rod and the bell crank to the compression rod to cause the compression rod to reciprocate between first and second positions. The shift tube is rotatable about its axis for shift of gear. The compression rod is operatively connected to an interlocking device such that the interlocking device prevents rotation of the shift tube when the compression rod is in the first position and allows it when the same is in the second position.
