PURPOSE: To increase the adhesion strength between a core metal blade part and a crawler body and improve rigidity of the crawler itself and durability.

CONSTITUTION: Left and right blade parts 1A in pair are connected integrally by a connection part 1B at the center, and a core metal 1 for elastic crawler is embedded in an endless strip shaped crawler body 3, and a projection part 5 (or/and a recessed part) is formed over nearly the whole surface on the surface of the counter-grounded side of the blade part 1A, and the adhesion surface area is increased, and the relative shift in the lateral direction (or peripheral direction) between the core metal 1 and the crawler body 3 is suppressed.
