Abstract
A mold heating device for heating a tire mold (M) for a green tire (T) includes an upper ring member (11) and a lower ring member (12) arranged so as to face one other in a specific direction with the space in which the tire mold (M) is disposed therebetween. A plurality of nonmagnetic members (13) are disposed at a plurality of positions aligned in the circumferential direction of the ring members (11, 12) with spaces therebetween so as to connect the upper ring member (11) and the lower ring member (12). Ferromagnetic non-conductive members (14) are provided on the inner surfaces of the nonmagnetic members (13), and a coil (15) is supported by the nonmagnetic members (13) with the ferromagnetic non-conductive members (14) therebetween so as to surround the space where the tire mold (M) is disposed from the outside in the direction perpendicular to the specific direction.
