PROBLEM TO BE SOLVED: To provide a travel operating device of a working vehicle capable of enhancing the operability in the on-road traveling by effectively utilizing an existing configuration in a traveling device of the working vehicle in which the output of an engine is transmitted to the traveling device via a hydrostatic type continuously variable transmission. SOLUTION: In the travel operating device of a working vehicle which is constituted to transmit the output of an engine 1 to a traveling device via a hydrostatic type continuously variable transmission 4 and has a neutral urging mechanism to urge the hydrostatic type continuously variable transmission 4 in a neutral condition by a manual operation tool 11 to operate the hydrostatic type continuously variable transmission 4, a rotary cam 19 interlocked with a rotary shaft 17 of the hydrostatic type continuously variable transmission 4, and a rocking positioning body 20 to be abutted on and urged by the rotary cam 19, an interlocking mechanism in which an operation unit 13 of an accelerator device 2 of the engine 1 is operated in the speed-increase side when the rocking positioning body 20 of the neutral urging mechanism is rocked as the speed-increasing operation of the hydrostatic type continuously variable transmission 4.
