The present invention relates to a crawler indicating an abrasion limiting timing and, more specifically, to a crawler indicating an abrasion limiting timing which is a new technology of a new concept capable of informing a user about a replacement timing in case of the abrasion of lugs of the crawler and improving the durability of the crawler by preventing an intake of various kinds of foreign materials into a sprocket hole. A worker misses a crawler replacement timing as the worker is unable to figure out a degree of the abrasion of the crawler, thus a crawler disclosed in the past is unable to present its performance. In addition, cracks are generated as the foreign materials received through a sprocket hole damage an adhering part between a core metal and a rubber part, and the stress is focused on corner parts of the sprocket hole, thus a problem of a decrease in the durability occurs. To solve the problem, in the present invention, the crawler indicating the abrasion limiting timing ...
