摘要： 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 member 10a heats a tire mold M1 by heat conduction. An induction heating coil C1 is disposed on the side of the ferromagnetic metallic member 10a opposite the tire mold M1 to induction-heat the ferromagnetic metallic member 10a by generating magnetic field lines. A nonmagnetic conductor 30a is disposed on the side of the induction heating coil C1 opposite the ferromagnetic metallic member 10a to shield the magnetic field lines generated by the induction heating coil C1. A heating unit 100a including these elements heats the tire mold M1 storing a tire. A relative positional relationship among the nonmagnetic conductor 30a, the induction heating coil C1 and the ferromagnetic metallic member 10a is set by first spacers 71a and 72a and second spacers 21a to 23a.

摘要： A center mechanism of a tire vulcanizer is provided with a screwing mechanism provided with a screw shaft and a screw nut screwed onto the screw shaft, a motor for rotating the screw shaft so as to raise and lower an upper ring body, an inverter for controlling the motor, and a mechanical brake for retaining a predetermined position of the upper ring body so that a bladder retains a shaping state. Within a time range from start of a closing action of the upper die to contact between the upper die and the upper ring body, an operation of the mechanical brake is released and position control of the upper ring body by the inverter is started, and at least after the release of the operation of the mechanical brake, a position of the upper ring body is controlled by the inverter. By such a configuration, even when there is an erroneous operation of the brake or incorrect setting, it is possible to prevent damage and breakage of constituent parts and have a simple structure.
