<p><P>PROBLEM TO BE SOLVED: To provide a high-frequency induction heating apparatus having narrow width shaft part which, without changing the whole shape of a coil portion and a silicon steel material covering the coil portion in a semi-opening saddle type high frequency induction heating coil, can cope with the narrow width shaft part, wherein the existing structure of semi-opening saddle type high frequency induction heating coil can be used and the generation of melting part to one pair of side plates can be prevented and such trouble as the development of electric power loss and also, the lowering of heating efficiency can be avoided. <P>SOLUTION: In the semi-opening saddle type high frequency induction heating coil 2, the opposite side interval between one pair of coil portions 2a, 2b oppositely and parallely set and also, oppositely set to surfaces to be heated, are set to be wider than the length size along the opposite direction of the one pair of coil portions 2a, 2b. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
