PROBLEM TO BE SOLVED: To provide an elastic crawler for securing sufficient rigidity, and preventing an agricultural field by making it difficult to generate mud balls. SOLUTION: An outer rib 8 on a rolling passage face 7 is inclined backward in a rotary direction K as it goes to the outside in a crawler width direction, and is arranged to go in a space corresponding to two adjacent lugs 4A and 4B. Also, a rotary direction back face of an elastic crawler 1 of the rib 8 is inclined forward in the rotary direction as it goes to a peak of the rib 8. An inclined angle relative to an inner periphery 2n of a crawler body on the back face become steep as it goes to the outside in a crawler width direction. COPYRIGHT: (C)2007,JPO&INPIT
