Abstract
A center mechanism for a tire vulcanizer having a first cylinder whose stroke can be detected with a simplified structure achieves reduction in cost and improvement in working efficiency upon maintenance. The center mechanism expands, while the first cylinder 1 moves downwardly, a bladder 5 into close contact with an inner face of a green tire. A downward stop position of the first cylinder 1 is set in advance by a linear sensor 14. The stroke amount of the first cylinder 1 is detected by a stroke bracket 12 having a stroke portion 12a extending downwardly in parallel to the first cylinder 1 from within a stem 8 and provided so as to advance into the stem 8 together with a cylinder rod 1a, and a linear sensor 14 for detecting the stroke amount of the first cylinder 1 from the stroke portion 12a of the stroke bracket 12 remaining outside the stem 8.
