Claims

[Scope of utility model registration request]

A core metal 11 having a pair of left and right external retaining protrusions 18 inside the crawler body 10 made of a rubber-like elastic material.
are embedded at predetermined intervals in the longitudinal direction of the main body, and a pair of left and right passage portions 20 through which the rolling wheels 19 and the like pass are exposed from the crawler main body 10 and provided on each core bar 11. A pair of left and right passage portions 2 of each core bar 11 are arranged staggered in the direction.
0 offset in the longitudinal direction of the main body, the pair of left and right core metal bases 16 of each core metal 11 is set by the amount L of protrusion of each passing portion 20 to both sides in the longitudinal direction of the main body with respect to each core metal base 16. ₂ and _R2 are approximately equal, the crawler body 1 is offset in correspondence with the pair of left and right passage portions 20, and
A pair of left and right grounding lugs 14 on the ground surface side of 0 are provided corresponding to the offset direction of each core metal base 16, and the offset amount SR of the left and right pair of grounding lugs 14 in the longitudinal direction of the main body is determined by An elastic crawler characterized in that the offset amount SC is larger than the offset amount SC.
