Abstract
The present invention provides a heating unit capable of easily and inexpensively adjusting total impedance based on tire mold size so that a power source can be used at a high power factor, and a tire heating apparatus using the same. A ferromagnetic metallic memberheats a tire mold Mby heat conduction. An induction heating coil Cis disposed on the side of the ferromagnetic metallic memberopposite the tire mold Mto induction-heat the ferromagnetic metallic memberby generating magnetic field lines. A nonmagnetic conductoris disposed on the side of the induction heating coil Copposite the ferromagnetic metallic memberto shield the magnetic field lines generated by the induction heating coil C. A heating unitincluding these elements heats the tire mold Mstoring a tire. A relative positional relationship among the nonmagnetic conductor, the induction heating coil Cand the ferromagnetic metallic memberis set by first spacersandand second spacersto
