PROBLEM TO BE SOLVED: To provide a rubber crawler capable of reducing lug cutting of end parts of lugs in the cross direction formed on a crawler body. SOLUTION: An erected surface 9 inclined at a specified angle is formed on an outer end part 11 in the cross direction X of the first lug 7a and the second lug 7b, a base part 12 of the erected surface 9a of the first lug 7a is formed matched with an outer end 2b in the cross direction X of the crawler body 2, the base part 12 of the erected surface 9b of the second lug 7b is formed separated with a specified interval to the inward side in the cross direction X from the outer end 2b in the cross direction X of the crawler body 2, and a relation of (c-d)/10≤a≤(c-d)/6 holds good when the interval to the base part 12 of the erected surface 9b of the second lug 7b from the outer end 2b in the cross direction X of the crawler body 2 is prescribed as (a), length in the cross direction X of the crawler body 2 as (c) and length in the cross direction X of a core bar 4 as (d).
