PROBLEM TO BE SOLVED: To provide an elastic crawler in which, during running of a crawler-type running device equipped with which, vibration is suppressed and good earth removal performance is obtained.SOLUTION: An elastic crawler includes a crawler body 4 of an endless band-shaped rubber, plural core grids 2 embedded in the crawler body, and plural lags 13, 14 protruding from the outer peripheral surface of the crawler body. The crawler body includes a pair of trank roller travel bands 12 which extend in the circumferential direction on an inner peripheral surface and on which a trank roller of a crawler-type running device travels. The core grid is arranged between the lags adjacent in the circumferential direction. The lag, when projecting from the outer peripheral side to the inner peripheral side, is superimposed on the trank roller travel band between the adjacent core grids. Between lags adjacent in the circumferential direction on the outer peripheral surface, a built-up part 16, which extends to both sides in the width direction and is further built-up as compared with parts just proximal to the lags, is provided. The build-up part includes, on its surface, a groove 18 extending as the whole in the width direction of the crawler or plural rubber projections 21C. |
