ABSTRACT:
In a remote-control gearshift mechanism for a vehicle of the type including a control shaft extended in parallel with a steering column and movable in the axial direction and rotatable about its axis by a gearshift lever, a linkage for transmitting the axial and rotary movements of said control shaft to a transmission, a first spring loaded over the lower portion of said control shaft for normally biasing said control shaft upward to its neutral position which corresponds to a position intermediate between the ends of the stroke of said control shaft in the axial direction, a second spring loaded over the upper portion of said control shaft for normally biasing said control shaft downward to its neutral position, and stopper means for limiting the spring action of said each spring independently of each other in such a manner that said control shaft may be prevented from moving past its neutral position, whereby shift-lever-action feeling may be improved.
