PROBLEM TO BE SOLVED: To arrange with high precision a member superior in thermal conductivity to a rubber material in an unvulcanized protruding rubber block that is vulcanized to form a rubber protrusion.SOLUTION: The manufacturing method for a rubber crawler performs: a divided rubber block formation step that divides an unvulcanized protruding rubber block 114, which protrudes from the inner periphery of an endless rubber crawler 10 and becomes a rubber protrusion 14 in which a metallic member 32 is buried, at a position where the metallic member 32 is buried, to form divided rubber blocks 115 plurally divided; a protruding rubber block building step that joints divided surfaces 115A of the plurality of divided rubber blocks 115 to build the protruding rubber block 114 while fitting the metallic member 32 to a recessed portion 116 for fitting the metallic member 32 formed on the divided surfaces 115A of the divided rubber blocks 115; and a vulcanization step that vulcanizes the protruding rubber block 114 to form the rubber protrusion 14. |
