<p>The surface of a central lug perpendicular to the direction of travel and disposed in the embedded position of a core metal for interconnecting grounding lugs disposed on the right and left sides of the outer peripheral grounding portion of a rubber crawler and spaced a predetermined longitudinal distance therebetween, is curved as seen in a side view. Thus, at the time of driving the rubber crawler repeating back and forth movement, even if a large resisting force from the road surface due to an impediment, such as gravel, is subjected to the central lug particularly disposed close to a sprocket engagement section, the resisting force can be parried for dispersion to a suitable degree by such arrangement, so that there is no possibility of early peel occurring in the central lug or such peeling is prevented from extending to the grounding lugs connected thereto; thus, the life is prolonged.</p> |
