PROBLEM TO BE SOLVED: To improve an assembling workability and an assembling precision by preventing a position shift in directions other than a radial direction of a tread sector when vulcanization molds are assembled. SOLUTION: A tire vulcanizing device includes a plurality of the tread sectors 9 radially inward/outward slidably held on a lower plate 7, and an annular actuator 10 whose radially inward circumferential surface is a conical surface having the same inclination as the radially outward surface of the tread sectors 9 and which descends to move the tread sectors 9 radially inward. There are mounted on an upper surface of the lower plate a sector receiver 19 composed of a pair of receiving surfaces 20 holding the sectors by making the tread sectors 9 straddle. Each sector receiver 19 has an engagement part 22 composed of a pair of tilting surfaces 20A extending mutually obliquely along a sliding movement direction in a V shape or in an inverted V shape to the central side of the receiving surfaces 20 and 20. The bottom surface SB of the tread sectors 9 includes a part 24 to be engaged having the same slope as the tilting surface 20A and slidably engaging with the engagement part 22.
