and forming a large number of left and right pairs of guide protrusions protruding from the inner circumferential surface of the crawler show on the core metal,
A locking portion that engages with a drive sprocket of the crawler traveling device is formed in the opposing gap between the pair of left and right guide projections, and the top of each guide projection protrudes further toward the center of the crawler shoe than the locking portion. In a rubber crawler forming a guide surface for a tensioning idler and a guide roller of a traveling device, the longitudinal ends of the crawler shoe of each pair of left and right guide protrusions are connected to the respective pairs of left and right guide protrusions adjacent to each other in the longitudinal direction of the crawler shoe. 1. A rubber crawler slippage prevention device, characterized in that the crawler shoes are formed at both ends thereof with overlapping portions that overlap each other in the width direction of the crawler shoes with a gap in which the crawler shoes can be bent in the longitudinal direction. (2) The overlapping portion forms a protrusion by bending and extending one end portion of each pair of left and right guide protrusions located in the same longitudinal direction of the crawler shoe in the width direction of the crawler shoe, and the crawler shoe of the protrusion 2. The rubber crawler slip-off prevention device according to claim 1, wherein the inner side in the width direction is arranged on the outer surface of the other end of the pair of adjacent left and right guide projections. (3) A notch is provided at one end in the same longitudinal direction of the crawler shoes of each pair of left and right guide protrusions, while a notch is provided at the other end of the pair of left and right guide protrusions that are adjacent to each other in the longitudinal direction of the crawler shoes of the guide protrusions. 2. The rubber crawler slippage prevention device according to claim 1, further comprising a stepped portion that fits loosely into said notch.
