Title: Bead ring locking mechanism of tire vulcanizer

Abstract: A bead ring locking mechanism restricts the relative turning of a tubular lifter moved upward or downward on the outside of a central mechanism outer casing with respect to an annular bead ring attached to the outer circumference of the lifter to form a part of a die. The locking mechanism includes a stopper member installed at the bead ring and attached so as to move back and forth with respect to the lifter, and an actuating member which moves the stopper member from the bead ring to the lifter. A recessed portion is formed at the lifter, a raised portion is formed at the stopper member, and the raised portion is fitted into the recessed portion by pressing the stopper member to the lifter using the actuating member.
