<P>PROBLEM TO BE SOLVED: To provide a front wheel steering device for a working vehicle capable of detecting a steering direction and steering angles of a plurality of stages while arranged switches are to the reduced number. Ž<P>SOLUTION: The front wheel steering device 20 is constituted so as to be provided with a shaft-like cam member 45 having large diameter parts 45a, 45c, 45f and small diameter parts 45b, 45d, 45e, 45g; a position detection cylinder 43 penetrated/arranged with the shaft-like cam member 45; and a steering position detection device 40 comprising a left detection switch 41 and a right detection switch 42 fixed to the position detection cylinder 43. The shaft-like cam member 45 is moved based on steering operation, can output a plurality of numbers of state variations according to the steering angle during when it becomes in the neutral state to the maximum steering angle, and can detect the steering angle and the steering angles of the plurality of stages.
