A torque tuning method includes a high-frequency induction heating apparatus that generates a magnetic field from a coil by passing an alternating current (i) to the coil, which is arranged so as to be separated from an outer housing. By passing the current (i) having a predetermined frequency from the high-frequency induction heating apparatus to the coil, a ball portion is induction-heated by a magnetic field generated from the coil through which the current (i) flows, and after the ball portion has reached a temperature at which a ball seat can be deformed by induction heating, the current (i) is stopped and the ball portion is cooled.
