<p>PURPOSE: To provide a high frequency induction heating coil body for tempering-heating with which the preparing time according to change of machine kinds can be shortened and the tempered quality can be obtained at better than that of the conventional method at a low cost. CONSTITUTION: In the high frequency induction heating coil body for induction-heating the outer peripheral surface of a shaft-like member(e.g. inner shaft 2) having plurality of different diameters to the outer peripheral part, or the inner peripheral surface of a cylindrical member(e.g. outer ring 41) having different diameters to the inner peripheral part, this coil body is provided with plurality of linear-shaped heating conductors 22-25 disposed as parallel to the axial direction of the shaft-like member or the cylindrical member and also, disposed as facing to the outer peripheral surface of the shaft-like member or the inner peripheral surface of the cylindrical member, a connecting conductor 26 connected with the respective end parts of the plurality of heating conductors and connecting conductors 27, 28 for connecting the respective other end parts of plurality of heating conductors and lead parts 30, 31 for supplying electric power connected to a high frequency power source 29.</p> |
