A rubber crawler having a specified rotation direction includes a crawler body that is formed in an endless shape and includes plural lugs. The plural lugs are provided at the crawler body, project out from an outer peripheral face, as viewed from a crawler outer peripheral side, are allocated to one side and another side in a crawler width direction so as to be alternately disposed on progression along the crawler peripheral direction on each side of a central line passing through a crawler width direction center, and extend at an angle to the crawler peripheral direction from an end portion on the central line side toward a crawler width direction outer side and toward an opposite side to a crawler rotation direction. In a cross-section of the lugs taken along the crawler peripheral direction, an angle formed between each apex side portion of tread-in-side wall faces on the crawler rotation direction side and the outer peripheral face is 90 degrees or greater, and is smaller than an angle ¸2 formed between each apex side portion of a kick-out-side wall faces on the opposite side to the crawler rotation direction and the outer peripheral face. |
