ABSTRACT:
Gear changing mechanism comprises spaced-apart camming plates and three gear changing levers mounted on a common axis which extends between the camming plates. The levers have control arm portions which have slots to receive a camming pin by means of which the levers are selectively oscillated with respect to the common axis. Camming means on the camming plates controls the movement of the camming pin to determine which lever will be oscillated by the camming pin. The camming pin, in turn, is controlled by a gear shift lever to which the camming pin is linked.
