PROBLEM TO BE SOLVED: To materialize a low-cost travel transmission structure of a working vehicle capable of preventing a working vehicle from moving during a temporary stop. SOLUTION: A travel transmission structure of a working vehicle transmits power from an engine 1 to travel devices 24, 39 through the medium of a transmission 6 and forward/backward movement switching device 33, and consists of a first operation means for operating the forward/backward movement switching device 33 to the forward travel position when a speed change operating tool 56 is operated from a neutral position N to a forward travel position F and for operating the forward/backward movement switching device 33 to a reward travel position when the speed change operating tool 56 is operated from the neutral position N to a reverse travel position R and of a second operation means for operating a plurality of speed change positions with different transmission ratios together to a transmitting condition in the transmission 6 and interrupting power transmission on the upstream side of the transmission 6 when the speed change operating tool 56 is operated to the neutral position N.
