PURPOSE: To reduce the occurrence of peel phenomenon between a core bar and rubber as much as possible and to improve durability of a rubber crawler in a core bar for a rubber crawler mounted on the running part of a construction machine and a machine for civil engineering works. CONSTITUTION: In a core 1 embedded in a rubber resilient body, through-holes extending through the inner and outer surfaces are formed in the right and left areas of the core 1. Rubber vulcanized and adhered to the inner and outer surfaces of the core 1 is integrally formed by means of a rubber material with which the through-holes are filled. |
