PROBLEM TO BE SOLVED: To provide a tire molding device which is excellent in an air rejection effect, and high in versatility to a tire size. ! SOLUTION: An inner shoe support mechanism 9 which supports a plurality of inner shoes 8 arranged along a circumferential direction of a main shaft 1 is arranged between a pair of bead lock devices 2 on the main shaft 1 so as to be freely expandable toward the outside of a radial direction of the main shaft 1, inside rollers 10 which abut on an internal peripheral face of a primary green tire G when the inner shoes 8 are expanded are installed at tips of the inner shoes 8, respectively, and relative drive means 12 is added to the inner shoe support mechanism 9 so that rotation speeds of the bead lock devices 2 around the main shaft 1 and a rotation speed of the inner shoe support mechanism 9 around the main shaft 1 differ from each other. !
