摘要： A structure for a running system, in a work vehicle, has right and left running wheels, hydraulic cylinders extensible and retractable in opposition to each other in response to axle-tilting displacement of the wheels as they rise and lower in turn in opposition to each other, a conduit connecting the cylinders with each other with an on-off valve interposed therein to be arbitrarily maneuverable thus to enable the lock up of both cylinders, and, a supply conduit made connectable to the cylinder-connecting conduit. There are provided valves in order to permit oil to be supplied only when inner pressure within this cylinder-connecting conduit has dropped to show negative pressure below a preset threshold.
