PROBLEM TO BE SOLVED: To perform the folding-back of the periphery of a bead part at a low speed by enhanced pressing force in a tire folding-back molding. SOLUTION: This tire molding machine is equipped with a folding-back mechanism having a finger for folding back a tire constituent member around a bead core and a cam 120 rotated accompanied by the shaking of the folding-back finger 101 is integrally provided to the folding-back finger 101. The finger 101 receives the drive force of a drive body 130 through a cam follower 122 and the cam 120, both of which are energized by a spring, to be opened. The cam 120 is rotated accompanied by opening while contracting the energizing spring of the cam follower 122. The spring is contracted not only to decelerate the opening speed of the finger 101 but also to raise the pressing force to the tire constituent member K of a finger roll 104.
