A shift operating structure for a work vehicle is provided to perform easily a speed-maintaining operation of a hydrostatic continuously variable transmission and to simplify a structure of a speed-maintaining unit. A shift operating structure for a work vehicle includes: a shift pedal(12) for performing a shift operation of the hydrostatic continuously variable transmission; a speed-maintaining unit maintaining the shift pedal at a desired forward shift position; a speed-maintaining lever(27) disposed adjacent a lateral side of a driver seat; a retaining member(29) displaceable by an operation of the speed-maintaining lever in an operational direction and in an opposite direction to the operational direction; and a restraining member(28) movable in a first direction and a second direction opposite to the first direction, in association with an operation of the shift pedal, the restraining member being engaged with the retaining member at a plurality of positions, and movement of the shift pedal in the direction toward the neutral position thereof is prevented by the engagement between the restraining member and the retaining member. |
