It is to provide a method of manufacturing a rubber crawler which enhances a degree of freedom in the handling in a vulcanization-shaping of a crawler part and largely improves vulcanization shapability and operability and facilitates an arrangement of an auxiliary device or the like. In a method of manufacturing a rubber crawler comprising a first vulcanization step of vulcanization-shaping by simultaneously heating and pressing inner circumferential side rubbers (2A, 2B) and ground side rubbers (3A, 3B) having a length corresponding to about a half circumferential length of an endless ring-shaped reinforcing cord (1) with a middle mold (6) arranged in an inner circumferential side of the reinforcing cord (1) and upper mold (4) and lower mold (5) arranged up and down on an outer circumferential side of the reinforcing cord (1) and a second vulcanization step of vulcanization-shaping rubbers having a length corresponding to a remaining half circumferential length in the same manner as described above, at least a middle mold (6) is heated at each step by flowing heat medium through flow paths (7) formed in the mold, whereby the thickness of at least the middle mold (6) is made thin.
