Object: To provide a method of manufacturing a sealant containing tire tube, which is capable of simply opening a sealant filling hole without use of any specialized jig, and a vulcanizing die therefor. Solving Means: A vulcanizing die 30 includes an upper die 30a, a lower die 30b, and a filling hole opening device 50. The filling hole opening device 50 includes a linear actuator 51, a drive shaft 52, and a cutter 53. The lower die 30b has a cutter passage 32 which passes through the vulcanizing die 30 from outside to inside, and a cut piece recovery passage 33 which extends from the outside of the vulcanizing die 30 to a portion, near the inner opening end, of the cutter passage 32. The drive shaft 52 of the linear actuator 51 is inserted in the cutter passage 32, and the cutter 53 is fixed to one end of the drive shaft 52. <IMAGE> |
