Abstract: PROBLEM TO BE SOLVED: To prevent a misoperation of a manual operational device in a case where a working vehicle is constructed in such a manner that the first and the second implements can be operated to the acting side or the standing side by the single manual operational device. SOLUTION: The working vehicle is provided with the first operation path 31 which extends to a specified direction from the first position A1, the second operation path 32 connecting the second and the third positions A2 and A3, and the third operation path 33 which extends from the end of the first operation path 31 on the side opposite to the first position A1 in such a direction as to cross the first operation path 31 and is connected to a part near the second position A2 of the second operation path 32, and the manual operational device 29 is guided through these operation paths. The part 33a on the side opposite to the first position A1 of the third operation path 33 is made tilted so that it is dislocated toward the first position A1 with going from the first operation path 31 to the second operation path 32.
