The bridging center has at least one projection projecting from the wings in a longitudinal direction of the rubber track. Projections of the core bars embedded in the elastic member overlap with each other to form a continuous passage for a track roller. As an alternative, the core bar includes a driving center protrusion provided at the center of the core bar and adapted to engage a sprocket wheel for driving the rubber track and track roller traveling surfaces extending along the driving center protrusion on both sides thereof. Sprockets for driving the rubber track is formed in the circumference with opened recesses alternately positioned in its both surfaces and engaged with the driving center protrusions of the core bars.
