PROBLEM TO BE SOLVED: To provide a rubber crawler wherein damage at a portion where a track roller rolls is suppressed. SOLUTION: In the rubber crawler consisting of a band-like body 1 in which a plurality of core bars 2 are berried and fixed in a rubber layer 1a together with a reinforced layer 5 and their end parts are linked in a manner twistable around each other between the driving wheel 4 and a driven wheel intervened with the track roller 3 and held in an endless manner, the core bar 2 is structured by a pair of projections 2a, 2b for separating and forming a single route S, having an outside wall facing against a side wall of the track roller 3, for passing the driving wheel 4 and the driven wheel in a clearance M between inside walls and a pair of blades 2c, 2d which are integrally continued with base parts 2' of the respective projections 2a, 2b at their root portions wherein end edges in the width direction of the rubber crawler are arranged as tip ends. A multi-stage slope consisting of a plurality of level differences of which angles become gradually smaller toward the base parts of the projections is provided for each outside wall of the respective projections 2a, 2b.
