Abstract
A rubber crawler comprises an endless rubber crawler belt which extends over a sprocket and an idler tumbler of a vehicle, and has a running surface formed on its inner circumference and on which a plurality of rollers roll, and a plurality of cores each having a base embedded in the belt and arranged perpendicularly to the longitudinal direction of the crawler belt at a proper mutual spacing longitudinally of the belt. Each core has an extended core part. The extended core part has a surface corresponding to the running surface along which the rollers are rolled, the core surface being wider longitudinally of the crawler belt than the width of the base of the core.
