PROBLEM TO BE SOLVED: To reduce the occurrence of vibration of a rubber crawler, and to reduce winding resistance to a sprocket and an idler by embedding the blade parts and the overhang parts of core metal in a rubber elastic body, and setting an overhang angle to the inside of the overhang parts to a specific range. SOLUTION: Blade parts 4, 4 and overhang parts 5, 5 are embedded in the rubber elastic body of this rubber crawler. The outside surface of the overhang parts 5 is formed as a single or plural planes or curved surfaces. The overhang parts 5 desirably overhang toward the inside of core metal 1. When an overhang angleθto the inside of these overhang parts 5 is not more than 10 degrees, the rubber crawler becomes the shape of externally enclosing these overhang parts 5 when being wound round a sprocket and an idler, so that winding resitance increases. While, when the overhang angle exceeds 30 degrees, it is not desirable since a rolling wheel vertically moves this time when the rolling wheel rolls. A desirable range of the overhang angleθis 15 to 25 degrees.
