TIRE VULCANIZING APPARATUS

PROBLEM TO BE SOLVED: To provide a tire vulcanizing apparatus which suppresses the occurrence of a bank in the vicinity of a bladder equatorial point while suppressing the occurrence of wrinkles during the expansion of a vulcanizing bladder. SOLUTION: When the length (tire meridian line cross section total length) in a meridian cross section along a tire lumen surface S between the bead toe ends et and et of a finished tire T1 is At, the length (tire circum-total circumference length) of a tire total circumference passing through a tire equatorial position ct on a tread lumen surface Sc is Bt, the length (bladder meridian cross section total length) of the meridian cross section along a bladder outer surface between toe points eb and eb in the standard state of the vulcanizing bladder 3 is Ab, and the length (bladder total circumference length) of a bladder total circumference passing through a bladder equatorial point cb is Bb, formula (1); Ab≤0.7×At and formula (2): Ab×Bb≥0.48×At×Bt are satisfied.
