PROBLEM TO BE SOLVED: To effectively and economically prevent an edge cut phenomenon during traveling or working occurring in the crawler width direction end of a rubber crawler. SOLUTION: This rubber crawler is made by burying core metals at constant intervals in the peripheral direction of the rubber crawler in a rubber crawler body having an endless rubber belt band body shape formed by a rubber elastic body, etc. A high hardness intermediate rubber layer formed by a high hardness rubber elastic body having higher rubber hardness than those of other rubber elastic bodies forming the rubber crawler body is interposed over the outside of a rubber crawler width direction end from at least a lower side on a ground contact face side at the end of a core metal longitudinal direction (rubber crawler width direction). The rubber elastic body of the rubber crawler body is made to have a multilayered structure of two or more layers. COPYRIGHT: (C)2004,JPO
