<P>PROBLEM TO BE SOLVED: To provide a tool for high-frequency hardening, with which hardening can be uniformly made in a hardening range while hardening is not made in hardening-unnecessary range, in the high-frequency hardening of a workpiece having the hardening-unnecessary range near the hardening range. <P>SOLUTION: The tool for high-frequency hardening includes: a shielding ring 2 formed with an electric conductive material having a figure similar to a heating coil; and fitting tools 3 for fitting the shielding ring to the heating coil in an electrically-insulating state. An axial directional position adjusting mechanism 5 and a diameter directional position adjusting mechanism 6 are included, in each of the fitting tools 3, for adjusting the position of the shielding ring 2, which is relative to the heating coil, to a coil axial direction and coil diameter direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
