PROBLEM TO BE SOLVED: To provide a mold for manufacturing belts capable of easily manufacturing belts of various kinds. SOLUTION: The mold 10 for manufacturing belts includes the inside mold 12, molding mold 16, inner outside mold 18 and outer outside mold 20. In the vulcanization process the belt material wound round the outer peripheral surface 12O of the inside mold 12 is pressed against the inner peripheral surface 16I of the molding mold 16. As a result a V-ribbed belt and the like having a rib shape corresponding to the shape of the inner peripheral surface 16I of the mold 16 is manufactured. In the belt manufacturing mold 10, the molding mold 16 and the inner outside mold 18 are separate bodies, and the mold 16 is exchangeable for a plurality of molding molds different in the shape of the inner peripheral surface from the mold 16, so that it is possible to manufacture the V-ribbed belts of various kinds easily and selectively.
