A steering control device (20) for a working vehicle includes an electric motor device (34) that generates an assistance torque to a steering column (33), and an inverter (43). The steering control device (20) includes a load torque sensor (39) that is attached between the electric motor device (34) and a load portion of a steering mechanism unit (21) to detect a load torque applied on a steering system, a steering load torque calculating section (41) that calculates a steering load torque based upon an output value of the load torque sensor (39), and an assistance torque calculating section (42) that adds the steering load torque outputted from the steering load torque calculating section (41) and a target steering torque input from an exterior to calculate an assistance torque to command the electric motor device (34) and command the inverter (43).
