Abstract
A post-cure inflator for inflating and cooling a vulcanized tire is disclosed. A lower rim mechanism is easily and certainly fixed, the whole apparatus is miniaturized, and the degree of freedom in designing when the lower rim mechanism is moved is made higher. The lower rim mechanism is lifted so that a locking shaft attached to an upper rim mechanism enters a fitting portion of the lower rim mechanism. After that, the locking shaft is rotated to be engaged with the lower rim mechanism, thereby connecting the lower rim mechanism via the locking shaft to the upper rim mechanism. A tire is inflated and cooled while being held by the upper and lower rim mechanisms. Guide plates are fixed to the upper rim mechanism so as to be along the locking shaft. Insertion grooves are formed in the lower rim mechanism. When the locking shaft enters the fitting portion, the guide plates are inserted into the insertion grooves.
