In a steering system for a tracked vehicle, the pressure oil flowing into the cylinder in excess of the capacity of the cylinder is transferred to a tank through a variable throttle whose throttle amount increases as the steering lever is operated. A steering device for a tracked vehicle, which includes a return pressure oil flow path and a pressure oil communication path that diverts pressure oil in the pressure oil flow path to cylinders related to other operations.
