PROBLEM TO BE SOLVED: To quickly shift by surely returning to an original state when stopping stepping, by surely shifting by the stepping, with a constitution for shifting a trunnion shaft of a hydraulic continuously variable transmission by an advance pedal and a retreat pedal. SOLUTION: This working vehicle transmits driving force of an engine to a travel device via a hydraulic transmission. When installing the advance pedal 115 and the retreat pedal 116 on one end of a pivot shaft 119 pivoted on a machine body, one pedal of the advance pedal and the retreat pedal is loosely fitted to the pivot shaft by being returnably energized by a return spring 128, the other pedal is fixed to the pivotl shaft, and a return spring 156 of this fixed pedal is made to act on the other end of the pivot shaft, and for rotating the travel device to the advance side by stepping of the advance pedal and rotating the travel device to the retreat side by stepping of the retreat pedal, the advance pedal and the retreat pedal are interlocked with and connected to the trunnion shaft for shifting the hydraulic transmission.
