ABSTRACT:
A coreless rubber crawler has a tension body embedded in an endless rubber elastic body in the longitudinal direction thereof, lugs (7) formed at the outer peripheral surface of the elastic body, central projections (2) formed at the center in a width direction of the inner peripheral surface of the elastic body at regular intervals in a longitudinal direction of the elastic body, and drive projections (5, 6) engaging with sprockets and formed at both outer sides in a width direction of the inner peripheral surface of the elastic body at the same intervals as the central projections. Elongated detachment preventing projections (2A) that engage with rolling wheels (20) are formed such that the pitch between the central projections (2) is larger than the pitch between the drive projections (5, 6).
