Patent ID: 7458438

Claim:
A working vehicle with a speed maintaining apparatus, comprising: a plurality of wheels including at least one driven wheel; a vehicle body supported by said plurality of wheels; an engine supported by said vehicle body; a stepless transmission driven by said engine and capable of changing speed of rotational power to said driven wheel; a neutral return device for biasing said stepless transmission toward a neutral position; a change speed pedal operatively connected to said stepless transmission; a speed maintaining means for maintaining said stepless transmission in a desired speed position; a speed setting lever movable to a retreat position and to positions in a forward speed range for setting said stepless transmission to the desired speed position in which said stepless transmission is maintained by said speed maintaining means; a relay rocking element connected to said stepless transmission through an auxiliary rocking element pivotable relative to said relay rocking element; and a control member provided in said speed maintaining means to be movable with said speed setting lever, said control member contacting and retaining said auxiliary rocking element in response to a movement of the speed setting lever from and retreat position to a position in said forward speed range, thereby restricting movement of the auxiliary rocking element relative to the relay rocking element, and allowing displacement of the relay rocking element by an amount corresponding to an amount of operation of the speed setting lever in the forward speed range, and thereby allowing the stepless transmission to be operated to the desired speed position.
