Claim 0:
1. An elastic crawler, comprising:
a plurality of coupling portions arranged at equal intervals in a circumferential direction at a center in a width direction of a crawler body;
a plurality of steel cores, each steel core formed in the width direction, the each steel core alternately arranged between two coupling portions, from among the plurality of coupling portions, adjacent in the circumferential direction of the crawler body; and
two lug rows installed on an outer periphery of the crawler body at bath left and right sides of the plurality of coupling portions in the width direction,
wherein each lug row comprises a plurality of driving lugs, each driving lug arranged in an oblique direction with respect to the steel core of the corresponding lug row, and a plurality of connecting lugs, each connecting lug configured to connect two driving lugs, from among the plurality of driving lugs, adjacent in the circumferential direction of the correspond lug row, and
wherein the each driving lug of the each lug row has a length to straddle two steel cores adjacent in the circumferential direction, overlaps with one of the two adjacent steel cores in the circumferential direction at an overlapping portion on an inner end side close to the coupling portion, and overlaps with the other of the two adjacent steel cores in the circumferential direction at an overlapping portion on an outer end side far from the coupling portion,
wherein the each connecting lug of the each lug row is arranged with an inclination in an opposite direction to the each driving lug of the corresponding lug row, and overlaps with one of the steel cores at an overlapping portion between the overlapping portion on the inner end side of one of the two adjacent driving lugs in the circumferential direction and the overlapping portion on the outer end side of the other of the two adjacent driving lugs in the circumferential direction.
