Abstract:
PURPOSE: To prevent a range to be heated from reaching the inside of each end part of a work, and simplify the heating work when the inner side of a cylindrical work is heated. CONSTITUTION: A heating conductive body 41a of a coil body 41 is inserted in a work 10. Concentric rings 42, 42 are provided on each end side in the axial direction of the heating conductive body 41. The concentric rings 42, 42 are connected and fixed to the coil body 41 by a supporting means 43. Magnetic flux is prevented from spreading on the each end side of the heating conductive body by the concentric rings 42, 42. The concentric rings 42, 42 are inserted in each end part of the work 10 as the coil body 41 is inserted.
