<p>PURPOSE:To realize reduction in size of coil by pressurizingly inserting and fixing a protrusion formed like a pole integrated to the end surface of coil bobbin into the cylindrical part provided to the secondary terminal. CONSTITUTION:A side of secondary terminal 1' to be fixed to a secondary bobbin 2' is provided with a cylindrical part 103' and a protrusion 201' provided to the side end surface of bobbin 2' is inserted into the internal diameter of such cylindrical part 103'. The external diameter of cylindrical part 103' is engaged with clearance with a hole 802 provided to a case 8. Moreover, the external diameter of protrusion 201' is further provided with a plurality of ribs 202'. With such structure, it is no longer necessary to determine the size l in the axial direction for fixing the terminal 1' to the bobbin 2', the axial length of coil itself becomes shorter and thereby a coil can be formed small in size. Moreover, any under force is not applied to the protrusion 201' and crack is not generated by pressurizingly inserting said protrusion and fixing it with both ribs 202' and cylindrical part 103'.</p> |
