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.
