Rubber crawler

Abstract

Provided is a rubber crawler containing cored bars that is capable of firmly closing a sprocket hole and firmly compacting the earth and sand taken into a groove between rubber lugs when the crawler is on the ground to enhance the traction performance. A rubber crawler (10) in which multiple cored bars (20) are embedded at regular intervals in a circumferential direction of the crawler in an endless belt-shaped rubber body (11), endless belt-shaped tension member layers (30), which extend in the crawler circumferential direction on a crawler outer circumferential side relative to the cored bars (20), are embedded in the endless belt-shaped rubber body (11) at both sides of a center in a width direction of the crawler, and a sprocket hole (15) into which teeth of a sprocket (2), around which the rubber crawler (10) is wound, enter is formed between the cored bars (20) adjacent in the crawler circumferential direction at the center in the crawler width direction of the endless belt-shaped rubber body (11), the rubber crawler being characterized in that a bottom portion of the sprocket hole (15) is formed by a rubber lug (12).
