Patent ID: 8414278

Claim:
A tire vulcanizer for vulcanizing a raw tire, comprising: a mold for removably housing the raw tire; a medium path which is connected to the inner space of the raw tire housed in the mold and through which a heating and pressurizing medium for vulcanizing the raw tire flows; and a heating unit, provided to the medium path, for controlling a temperature of the heating and pressurizing medium flowing through the medium path, wherein the heating unit includes a heated body internally provided with a flow channel through which the heating and pressurizing medium flows, and an induction heating unit for heating the heated body through electromagnetic induction so as to heat the heating and pressurizing medium flowing through the flow channel, and wherein the medium path includes a piping member through which the heating and pressurizing medium flows, the heated body is configured from a part of the piping member of the medium path, the induction heating unit is configured from a magnetic force generating member which is disposed around the piping member configuring the heated body and which exerts a line of magnetic force to the piping member, and the heating unit includes a ferromagnetic nonconductive member disposed on the outside of the magnetic force generating member in a radial direction of the piping member configuring the heated body.
