作部。A rod-type interlocking mechanism that allows flexible operation of a traveling hydraulic continuously variable transmission 9 and its operating tool 10 in a forward speed increasing direction f when the continuously variable transmission 9 is in a maximum forward speed state F. 13, a control mechanism 14 is provided which automatically operates the operating tool 10 according to the workload, and a sensor 17 is provided which automatically stops the control mechanism 14 when the operating tool 10 is operated in a flexible operation. In the work vehicle, the interlocking mechanism 13 includes a rod 18 that is pivoted to one of a first interlocking member 11 interlocked with the operating tool 10 and a second interlocking member 12 interlocked with the continuously variable transmission 9. connect,
And the rod 18 is slidably engaged with the other, and a stopper 20 is attached to the rod 18 to prevent it from sliding against the first or second interlocking member 11.12 during a forward deceleration operation. A speed change operating section for a working vehicle in which a spring 21 is interposed between the rod 18 and the first or second interlocking member 11.12, which is deformed as the operating tool 10 is operated.
