PROBLEM TO BE SOLVED: To provide a shift operating part structure of a working vehicle that makes any vibration out of a hydrostatic type continuously variable transmission be hard to lee transmitted to a driver and simultaneously such a shift operation as being excellent in operating efficiency achievable. SOLUTION: This is a shift operating part structure of a service car that is linkedly connected with a shift operator and a shift operating shaft 13 of a hydrostatic type continuously variable transmission 12, and its auxiliary fulcrum shaft 17 is pivoted to a body clamping part 16 free of rotation around almost the same shaft center with a turning shaft center X of the shift operating shaft 13. With this constitution, a pin 20 projectingly installed in an auxiliary arm 19 integrally installed in this auxiliary fulcrum shaft 17 is engaged with a shift lever arm 14 integrally installed in the shift operating shaft 13, and this pin 20 and the shift operator both are linked and connected to each other via a linkage mechanism 22 being free of pushing and pulling operations.
