PROBLEM TO BE SOLVED: To provide an elastic crawler practically mounted on both a crawler type traveling vehicle for civil engineering works and a crawler type traveling vehicle for greening management. SOLUTION: The elastic crawler 1 is formed of a crawler body 3; a plurality of core metals 2 each having a plate-shaped wing 13; a tensile body 6 disposed on the outer peripheral side of the crawler body than the wing and buried in the crawler body; and two or more kinds of lugs 4a, 4b and 5 which protrude from the outer peripheral surface of the crawler body and are repetitively arranged in the circumferential direction of the crawler body on both sides in the width direction of the crawler body. Both circumferential edges of each wing extend in the width direction, and neighborhoods 14 of both edges are bent away from the tensile body. One or two kinds of grooves among a plurality of kinds of grooves dividing the circumferentially adjacent lugs are arranged at positions circumferentially overlapping with the core metal, and other kinds of grooves are arranged at positions not circumferentially overlapping with the core metal. The grooves circumferentially overlapping with the core metal have a smaller depth than the grooves not circumferentially overlapping with the core metal. COPYRIGHT: (C)2010,JPO&INPIT |
