A tire vulcanizer is provided in which upper and lower clamp rings can be positioned at a shaping position easily and smoothly with a simple engagement structure. The tier vulcanizer with a vulcanizer body (A) and a shaping unit (B) is configured that the upper and lower clamp rings (5, 6) are connected by an extendable shaft (5a) having an inner shaft (51) and an outer tubular shaft (61) so that the inner shaft is slidably fitted into an inside of the outer tubular shaft. A latch member (53) on the inner shaft is engaged with a step portion (63) on an inner surface of the outer tubular shaft, thereby positioning the upper and lower clamp rings at the shaping position.
