PURPOSE:To make it possible to accurately fix a green tire under pressure by a structure wherein a slidable holder, which is provided on a guide member laid normal to the axis center part of a molder, is whirlingly connected to the tips of a pair of right and left whirling arms through links. CONSTITUTION:A pressure fixing device 100 equipped with pressure fixing tools (pressure fixing means), a whirling mechanism 300 laid normal to a whirling center shaft part 200 (axis center line) and the driving part 400 of the whirling mechanism 300 are installed near a tire molding equipment 10. When a driving motor M rotates forward, a ball screw shaft 303 rotates forward through a sprocket 402, a chain 406, a sprocket 405, a speed reducer 403 and an output shaft 407. With the normal rotation of the shaft 303, a holder 304 slides leftwards and at the same time whirling arms 105a and 105b, which are connected respectively to the holder 304 through links 306a and 306b and equipped with a pressure fixing tool 101, are synchronously expanded horizontally so as to fix a grren tire W under pressure.
