PROBLEM TO BE SOLVED: To eliminate run-out of a car body and to improve ride comfort even when a steering wheel exceeds a neutral position on the opposite side after a steering operation of the steering wheel is canceled in a crawler type work vehicle provided with a neutral position return mechanism for returning the steering wheel to the neutral position. SOLUTION: When an operator cancels a steering operation, a change speed of a steering wheel turning angle is calculated by a controller. When the steering wheel exceeds a neutral position on the opposite side, it is determined whether the change speed of a steering turning angle is decreased or not, and when the change speed is decreased, it is determined that the steering wheel exceeds the neutral position by inertia, an operation signal output to a clutch of a forward and reverse switching device on the opposite side is restrained for a predetermined time.
