PURPOSE:To prevent the dismounting of a crawler track from a wheel and to prevent the deforming or breaking of core metals by forming treading lags within the projection area of the core metal. CONSTITUTION:A groove like recessed part 7 having U-shaped cross sectional area is formed at the center of an endless belt 1 in its longitudinal direction, core metals 8 being buried in said endless belt 1 with even spacing along its longitudinal direction but in the direction of its width, a concave 8' being formed on the center of said core metal 8 to fit in the inside face of the center recess 7 of the endless belt 1 in the buried condition. The lags 5 may be separated in two beneath the lower face of the recessed part 7 or may cover entire width but at least some portion of each lag is positioned within the projected area of the core metal 8. |
