To provide an elastic crawler reducing the manufacturing cost of a core bar without impairing a position deviation restriction function relative to a rolling wheel.

The elastic crawler 1 is provided with a crawler body 6 formed with engagement holes 6a; the core bar 7 having a pair of left and right guide projections 12 buried at a portion positioned between the engagement holes 6a and projected to the inner periphery side of the crawler body 6; and tension members 9 buried at both sides in the crawler width direction of the engagement hole 6a. The elastic crawler 1 is driven in a crawler circumferential direction by engaging an engagement claw of a drive sprocket with the engagement hole 6a while restricting position deviation in the crawler width direction relative to the rolling wheel by the guide projection 12. The core bar 7 is made to a shape having no wing only comprising a base 11 extending in the crawler width direction over a range corresponding to the engagement hole 6a and the tension members 9 positioned at both sides in the crawler width direction an the pair of left and right guide projections 12 integrally formed at both ends in the crawler width direction of the base 11.
