作構造。 Continuously variable transmission mechanism C for driving where the minimum speed is zero or close to zero, and forward/reverse switching mechanism D
This operating structure for running a working vehicle is provided with a single reciprocating shift lever 34, and a detent mechanism 35 is provided between the shift lever 34 and the switching shaft 33 of the forward/reverse switching mechanism D. The gear shift lever 3 is connected in an interlocking manner through the provided elastic flexibility means G, and even after the forward/reverse switching operation is completed, the shift lever 3 continues to move in the operating direction.
4 so as to be operable to move, and output a push/pull operation force under the same conditions regardless of whether the shift lever 34 is moved from the neutral position of the forward/reverse switching mechanism D to either forward or backward. A driving operation structure for a working vehicle in which the speed change lever 34 and the speed change shaft 32 of the continuously variable transmission mechanism C are interlocked and connected via H.
