PROBLEM TO BE SOLVED: To simply and effectively reduce vibrations even in a form that a core bar is embedded and a rolling wheel rolls outside a guide protrusion. SOLUTION: Core bars are embedded inside a crawler body made of an elastic material at predetermined intervals in a peripheral direction. A lag is formed on an outer peripheral face, and a guide protrusion is formed on an inner peripheral face. A rolling part is formed on an inner peripheral face outside the guide protrusion in a width direction, and a raised part projecting inwardly is formed in each core bar unembedded area of the rolling part. The raised part is formed of two crests and a valley between the crests, and/or an inwardly indented face is formed from a bottom to each crest. COPYRIGHT: (C)2004,JPO
