Abstract
A rubber crawler track in which a local side displacement is more effectively prevented to effectively prevent wheel run-off, which can reduce traveling vibration, and in which separation of metal cores is prevented for improved durability of the rubber crawler track and for reduced costs. The expression of Δr≦r≦2Δr is satisfied, with 'r' being the distance, in the circumferential direction of the rubber crawler track, between ends of horizontal protrusions () facing each other between adjacent metal cores () embedded in a rubber crawler body in a horizontal state of the rubber crawler track, 'h' being the distance from a steel cord () layer embedded in the rubber crawler body to the core metal horizontal protrusions (), and Δr being a value obtained by Δr=2πh/n where “n” is the number of sprocket teeth of a traveling device.
