PROBLEM TO BE SOLVED: To solve those problems that the traction force is reduced, and vibrations and noises are generated regarding an elastic endless crawler belt travel device which is applied to an agricultural tractor and so forth. SOLUTION: The right and left rolling wheels of an equalizer in this elastic endless crawler belt travel device are provided in a manner to be positionally shifted in the crawler belt moving direction. The positional shift dimension is set 1/2 to the burial pitch of a core bar which is buried in the crawler belt. Also, a removal preventing protuberance which is formed on the core bar is moved between the right and left rolling wheels of the equalizer which is provided in a manner to be positionally shifted in the crawler belt moving direction. In addition, on the wound internal surface side of the crawler belt, ridges are formed on the right and left external sides of the removal preventing protuberance, and also, at right and left side areas of an engaging hole with which the teeth of a driving sprocket are engaged, and the right and left rolling wheels of the equalizer which are positionally shifted in the crawler belt moving direction are made to tread and roll on the ridges.
