To prolong a life of a vulcanizing mold by dispersing a clamping pressure tending to concentrate on a center side of the vulcanizing mold.SOLUTION: According to the present invention, a green tire is put into the vulcanizing mold together with a rigid core for vulcanization molding. A tire vulcanizer includes a first ring 6 having an annular shape concentric with a vulcanizing mold 3 and being disposed between a base 4 and a lower plate 5, and a second ring 22 having an annular shape concentric with the vulcanizing mold 3 and being disposed between a reinforcing beam 21 and an upper plate 7. A lower die portion 3L is attached to the lower plate 5, and an upper die portion 3U is attached to the upper plate 7. Lifting means 8 for moving the upper plate 7 up and down comprises a pair of tie rods 20 rising from the base 4, the reinforcing beam 21 guided by the tie rods 20, and the second ring 22.SELECTED DRAWING: Figure 1 【課題】 加硫金型の中央側に集中傾向となる締め付け圧力を分散させ、加硫金型の長寿命化を図る。【解決手段】 生タイヤを剛性中子ごと加硫金型に投入して加硫成形する。加硫金型３と同心な環状をなし基台４と下プレート５との間に配される第１リング６、及び加硫金型３と同心な環状をなし補強梁２１と上プレート７との間に配される第２リング２２を具える。下プレート５には下の金型部３Ｌが取り付き、上プレート７には上の金型部３Ｕが取り付く。上プレート７を上下に移動させる昇降手段８は、基台４から立ち上がる一対のタイロッド２０と、このタイロッド２０に案内される補強梁２１と、前記第２リング２２とを具える。【選択図】図１
