Provided is a rubber crawler wherein the rubber thickness of a rubber member interposed between a mandrel and a tooth section of a sprocket is uniform, resulting in durability being achieved in a situation where the tooth section of the sprocket engages a driving protrusion, causing driving force to be applied to the rubber crawler. The aforementioned rubber crawler is configured in such a way that with the mandrel (12) installed inside a rubber crawler body (10), a wing section (12a) is located in the width direction of the rubber crawler body (10); that furthermore, a pair of protrusions (12c, 12c) are covered with the rubber member, and a pair of driving protrusions (14,14) are formed on the inner peripheral side of the rubber crawler body (10); and that the pressing force due to rotational movement of the tooth section (32) of the sprocket is exerted on the pair of driving protrusions (14,14), resulting in the rubber crawler being driven into rotation. In this rubber crawler, the mandrel (12) is formed in such a way that the peripheral-wise width of a central section (12b) which exists between the pair of protrusions (12c, 12c) is shorter than the width of the wing section (12a) of the mandrel (12) and is constant at least up to the two outer sides of the base ends of the pair of protrusions (12c, 12c). |
