PROBLEM TO BE SOLVED: To realize the traveling property with a favorable balance by improving the soil discharging property, reducing the clogging of mud on the central section and the side sections, and enabling the propelling force to be effectively ensured regarding an elastic crawler which is used in wet paddy fields or semi-wet paddy fields. SOLUTION: This elastic crawler has a crawler main body 2 which is formed into an endless belt shape of an elastic material, and lugs 4 and 5 which are protrusion-molded on the ground touching surface side of the crawler main body 2. The elastic crawler is constituted of the longer lug 4 which is formed over approximately the total width of the crawler main body 2, and the shorter lug 5 which is shorter than the longer lug 4. Also, the longer lug 4 and the shorter lug 5 are arranged in parallel in the belt length direction of the crawler main body 2, and at the same time, a plurality (e.g., two piece) of the shorter lugs 5 are arranged in such a manner that the shorter lugs 5 may form a zig-zag shape between a pair of adjacent longer lugs 4.
