摘要： A shift adjusting device includes a cam plate and an arm. The cam plate is pivotable and operatively connected to a change speed interlocking mechanism extending between a shift pedal and a belt type stepless change speed device. The arm is also pivotable and operatively connected to a changeover interlocking mechanism extending between a switch lever and a backward/forward drive changeover device. The arm has a pin for engaging a control slot formed in the cam plate. The control slot includes an arcuate forward drive slot portion and an arcuate backward drive slot portion. When the switch lever is in a forward drive position, the pin lies in the forward drive slot portion. The forward drive slot portion allows a full stroke depression of the shift pedal, whereby a forward speed may be selected between minimum speed and maximum speed. When the switch lever is in a backward drive position, the pin lies in the backward drive slot portion. The backward drive slot portion allows only a half stroke depression of the shift pedal, whereby a backward speed may be selected between minimum speed and half the maximum speed.
