Problems to be Solved by the Invention A hydraulic transmission device capable of changing gears using hydraulic pressure, a manual interlocking mechanism having a manual lever for shifting the hydraulic transmission device, and a foot pedal having a single foot pedal. In a traveling operating device for a vehicle, etc., which is provided with an interlocking mechanism and a priority mechanism that prioritizes a single pedal pedal shift operation regardless of the shift selection position of the manual lever, between the two interlocking mechanisms. This priority mechanism gives priority to the operation of the single foot pedal no matter which gear selection position the manual lever is in, and when the foot pedal is removed, the gear changes to the gear selected by the manual lever. Therefore, for example, with the 1 manual lever positioned on the reverse high speed side, after changing the gear forward using the foot pedal,
If you remove your foot from the foot pedal, the vehicle will move backwards at the high speed selected with the 1 manual lever, which may be dangerous.
