の変速操作装置。 In a work vehicle in which power is transmitted from an engine 3 to a traveling device 4 by a traveling transmission system 2 equipped with a continuously variable transmission 1, a shift lever 5 of the continuously variable transmission 1 is used.
is provided so as to be able to rotate from a neutral position N around a rotational fulcrum O in forward speed increasing and reverse speed increasing directions, and a throttle operation section 6 of the engine 3 is attached to the speed change lever 5.
To interlock the connecting cable 7, one end of which is connected to the
The connection point P of the connecting cable 7 to the gear shift lever 5 is made variable in position in the rotational radial direction of the gear shifting lever 5, and the actuating body 8 interposed in the middle of the linking cable 7 is connected to the accelerator lever 9 of the engine 3. A gear shift operation device for a work vehicle, characterized in that the throttle operating section 6 of the engine 3 is operated in synchronization with the speed change lever 5 in proportion to the increase/deceleration operation of the gear shift lever 5.
