RUBBER CRAWLER AND RUBBER CRAWLER RUNNING DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce vibration of a rubber crawler running device having a belt body formed as endless and a traction lug when the rubber crawler running device on which a rubber crawler having a low rigidity part and a high rigidity part is mounted is operated. SOLUTION: In order to reduce a difference in rigidity between a first lug peripheral part with low rigidity and a second lug peripheral part with a high rigidity, the thickness in the longitudinal direction of a belt in the belt body of a second lug positioned in the second lug peripheral part is made smaller than the thickness in the longitudinal direction of the first lug positioned in the first lug peripheral part.
