A segment structure mounted on a wheel or an endless rubber track for increasing the driving force of off-road vehicles, civil engineering machines or construction machines is disclosed. A segment of a rubber elastic material mounted on the outer periphery of the wheels or the endless rubber track includes a bottom section adapted to be in contact with the wheel or the endless rubber track, a hollow section formed in the segment along the width of the wheel or the endless rubber track, and a stopper erected into the hollow section from the bottom section. The inner surface of the hollow section and the stopper are kept out of contact with each other under a static load.
