Abstract
An elastic crawler includes an endless elastic body; cores that each include a core body and a pair of protrusions; lugs, on the outer circumferential side of the elastic body, each disposed so as to avoid a crawler circumferential direction area corresponding to at least a portion of the core in the crawler circumferential direction; and grooves, on the crawler inner circumferential surface, each positioned outward in the crawler width direction from the pair of protrusions in a crawler circumferential direction area corresponding to the core, each of the grooves being recessed relative to crawler inner circumferential surface portions adjacent to the groove on both sides in the crawler circumferential direction.
