Abstract
An upper side mold is lowered without mechanical combination between the mold and a lowering force application device. A tire vulcanizing apparatus 1 includes a mold 2, a lowering force application device 25, and an attachment 4. The mold 2 includes a tread mold 6, an upper side mold 7U, and a lower side mold 7L. The lowering force application device 25 is disposed above the mold 2 and includes a rod 25a extending downward. The attachment 4 is fixed to an upper portion of the mold 2 without mechanical combination with the rod 25a. The attachment 4 includes a body 35 and an upward-downward movable portion 36 fixed to the upper side mold 7U. The upward-downward movable portion 36 lowers the upper side mold 7U upon receiving a lowering force F from the rod 25a.
