PURPOSE:To improve the durability of resilient member crawler by filling the opposite sides of T-shaped projection with rubber material thereby reducing distorsion of core metal upon application of shifted load. CONSTITUTION:A core metal 1 is provided with a pair of stopper projections P, P in T-shape in the central portion made of planar stripe member where the longitudinal width L' in groove F held between said projections P, P is made slightly shorter than the length L at the opposite ends. A rubber crawler 2 buried with the core metal 1 is formed such that T-shaped upper face of core metal 1 will be exposed from the rubber member and the opposite side sections (f) of T-shaped projection P is also filled with rubber material. Consequently, floating of core metal 1 due to variation of load to be applied during travel is prevented resulting in improvement of durability of rubber crawler 2. |
