To provide a crawler molding device capable of integrally molding and vulcanizing a tension member such as a steel cord under a fully tensile condition, and preventing deterioration of quality of an elastic crawler.
This crawler molding device 1 is equipped with an outside die 15 molding an outer periphery of an unvulcanized endless belt-like preliminary molding 2A, and an inside die 16 arranged opposite to the outside die 15 to mold the inner periphery of the preliminary molding 2A, so as to integrally mold and vulcanize the preliminary molding 2A between the inside die 16 and the outside die 15. A pressurizing means 17 is installed for moving the inside die 16 outwardly in a radial direction and pressurizing the preliminary molding 2A between it and the outside die 15 from the inner periphery side.
