PROBLEM TO BE SOLVED: To obtain an elastic crawler which keeps high tractive force, saves cost, and is difficult to be damaged. SOLUTION: The elastic crawler has a lug groups composed of a plurality of main lugs 4 and a plurality of auxiliary lugs 5. The main lug 4 is composed of a first tilting portion 4A tilting backward in a rotating direction X from a first end in a width direction of a crawler main body 3 toward a second end, and a second tilting portion 4B tilting forward in the rotating direction X. The first tilting portions 4A and the second tilting portion 4B are alternately disposed in the width direction, and continuously formed so as to spread over between both end portions of the crawler main body 3. The auxiliary lug 5 has length which does not extend all over between both end portions of the crawler main body 3, and is disposed at a generally center portion between the main lugs 4 adjacent to each other in a circumferential direction.
