ABSTRACT:
An elastic crawler having a crawler main body including an endless belt of rubber-like elastic material that is driven by friction with a friction drive wheel. A plurality of guide projections protrude from the inner circumferential surfaces of both lateral edge portions of the crawler main body at specified intervals in the longitudinal direction of the belt. Guide core bodies are embedded to the inside of the respective guide projections in the lateral direction of the belt. A plurality of main body core bodies are embedded in the crawler main body in the same positions as the guide projections in the longitudinal direction of the belt, and a plurality of laterally extending lugs protrude from the outer circumferential surface of the crawler main body at specified intervals in the longitudinal direction of the belt. The guide core bodies and main body core bodies are independent of each other.
