Gear-shift mechanism for manual transmission
This patent describes a gear-shift mechanism for a manual transmission comprising a housing for the transmission; a movable shaft mounted in place within the housing for both axial and rotary movements and being operatively connected to a manual shift lever to be axially shifted from its neutral position to a forward or reverse position in selecting operation of the manual shift lever and to be rotated at its shifted position in shifting operation of the manual shift lever; a shift-and-select lever fixed to an intermediate portion of the movable shaft; an interlock member rotatably mounted in place on the movable shaft and having a pair of interlock arms located at the opposite sides of the shift-and-select lever; means for restricting rotary movement of the interlock member and permitting axial movement of the same; a pair of resilient means for centering the movable shaft to retain the shift-and-select lever and the interlock member in their neutral positions; and first, second and third shift heads arranged in sequence within the housing.
