Abstract
A rubber crawler has: an endless rubber belt that is entrained about plural wheels; plural rubber projections that are disposed on the rubber belt and spaced apart from one another in a crawler circumferential direction, project toward an inner peripheral side of the rubber belt, and come into contact with the wheels to limit the movement of the wheels in a crawler width direction; and a low-hardness rubber portion that configures part of an inner peripheral surface of the rubber belt, is disposed between mutually adjacent rubber projections, and is formed by a rubber having a lower hardness than the rubber projections.
