PROBLEM TO BE SOLVED: To provide a control device of a travel transmission device for reducing an uncomfortable feeling caused when a speed difference between right and lift traveling devices is changed during turning. SOLUTION: A control part brings a clutch into an ON state by gradually increasing a transmission amount of power by the clutch in accordance with an operation amount of switching operation when a steering operation member operated artificially is switched from a first operation position to a second operation position. Furthermore, the control part brings the clutch into an OFF state by gradually decreasing the transmission amount of the power by the clutch with an increase in the operation amount when the steering operation member is operated from the second operation position to a third operation position, and moreover, gradually increases a braking force by a braking tool. However, when an operation speed of the switching operation of the steering operation member is greater than or equal to a prescribed speed, the control part gradually increases the transmission amount of the power until the clutch is brought into a transmission state, and then, gradually decreases the transmission amount of the power and gradually increases the braking force by the braking tool.
