In the working vehicle 141 having the engine 70 mounted to a travel machine body 142, a common rail type fuel injection device 117 which injects fuel to the engine 70, and a continuously variable transmission 159 which shifts power from the engine 70, a rotating speed N of the engine 70 is limited to two kinds, N#1 and N#2. Further, a change gear ratio of the continuously variable transmission 159 is changed and regulated in such a manner as not to change a vehicle speed of the travel machine body 142 before and after changing the rotation speed N whichever of the two kinds N#1 and N#2 the rotating speed N of the engine 70 is changed to.",
