To prevent rubber material entering between peripheral end faces themselves of segments upon vulcanization from remaining while tightly adhering to the peripheral end faces as it is when detaching a manufactured rubber crawler from both molds after vulcanization.
In the manufacturing apparatus 10 of rubber crawler, which forms the rubber crawler to be used by being wound in an endless belt shape between a driving wheel and a coupled driving wheel, a film 16 of a friction coefficient lower than respective friction coefficients on an inner peripheral face of an inner mold segment 14 and on an outer peripheral face of an outer mold segment 13 is formed on both peripheral surfaces 14a, 13a of each segment 14, 13 on at least one side of a plurality of inner mold segments 14 and a plurality of outer mold segments 13.
