PROBLEM TO BE SOLVED: To provide a traveling device for a working vehicle, allowing free setting of a turning condition during steering turning operation in various modes by inputting from a hydraulic continuously variable transmission to planetary gear mechanisms mounted in a transmission case. SOLUTION: The traveling device for the working vehicle comprises the transmission case 2 in which a gear train is mounted for steering turning with a pair of right and left planetary gear mechanisms 1 and a constant input or traveling power by a hydraulic continuously variable transmission 3 is inputted to the transmission case 2, containing a hydraulic pump 5 and a pair of right and left hydraulic motors 6 constituting a hydraulic continuously variable transmission 4 for inputting control power individually to the pair of right and left planetary gear mechanisms 1 during steering turning or a pair of right and left hydraulic pumps 10 and a hydraulic motor 11 constituting a hydraulic continuously variable transmission 9, and a steering clutch 7 in a passage for transmitting traveling power to the planetary gear mechanisms 1.
