Abstract
The known center mechanism in a tire vulcanizing machine is improved in that the center mechanism comprises condensate ejection means which can be accommodated within a member disposed in the center mechanism and which can be moved between the member and a condensate stagnating portion, a sleeve movable vertically within an upper ring by an operation of a pneumatic cylinder and adapted to be engaged with a part of the upper ring at its end portion to restrain a raised position of the upper ring, whose fixed height with respect to a rod of the pneumatic cylinder is variable, and a rotary member for restraining the position of the lower ring, whose engagement length with a receiving plate for the lower ring can be varied by continuous rotation thereof, and which can be fitted to and disengaged from a support member therefor through rotation by a predetermined amount.
