PROBLEM TO BE SOLVED: To secure safety without sudden start at excessive speed even under a situation that engine rotation speed suddenly rises at a time of engine start. SOLUTION: In a working vehicle provided with a correction means correcting engine rotation speed direction value in relation to operation amount of an accelerator means 18 based on comparison between a detection value As of an accelerator sensor 65 and pre-established reference value As0 on an engine rotation speed direction controller 70 converting detection value of the accelerator sensor 65 detecting operation amount of the accelerator means 18 and outputting the same to an engine control controller 55, a means judging existence of correction of engine rotation speed direction value is provided, and a conversion means converting default reference value Ad during idling rotation to a set value on a rotation speed increase side of the accelerator means 18 at a time of no correction judgment is provided.
