PROBLEM TO BE SOLVED: To reduce the replacement frequency of a sliding member in a mold for vulcanizing a tire using the sliding member. SOLUTION: In a mold, a plurality of sector parts for forming a tread pattern are formed on the periphery between upper and lower molds, a container ring 9, which is coupled with the periphery of the sector part through a guide part 10 and moves vertically along the peripheral surface of the sector part through a sliding member 20 is arranged, and each sector part is opened/closed radially by the vertical movement of the container ring 9. In this process, the outer surface 12a of a guide part 12 fitted to the sector part S and the inside surface 9a1 of the container ring 9 facing the outer surface 12a are formed in parallel surfaces, and the siding member 20 is installed between the parallel surfaces. |
