<P>PROBLEM TO BE SOLVED: To provide an elastic crawler which can reduce vibration in running to improve a degree of comfort and prevent the fall of lug adequately. <P>SOLUTION: The elastic crawler 14 includes a crawler body 17 which consists of an elastic body made of endless belt like rubber, a plurality of metal cores 18 which is laid inside of the crawler body 17 at a predetermined interval in a direction of the crawler circumference, and a plurality of lugs 20 which is arranged on the perimeter surface of the crawler body 17 at a predetermined interval in the direction of a crawler circumference. In the elastic crawler 14, the lugs 20 are arranged on a position where one side part in the direction of a crawler circumference is superposed on the perimeter side of the metal core 18 and the other side part off the direction of crawler circumference from the metal core 18 and moreover, for the lugs 20, at least in the crawler width direction domain of metal core 18, a radius R2 of the root part 35 in the other side part of the direction of a crawler circumference is formed larger than a radius R1 of the root part 35 in the same side part. <P>COPYRIGHT: (C)2013,JPO&INPIT |
