<p><P>PROBLEM TO BE SOLVED: To provide a choke coil and a transformer, allowing easy mounting of a winding formed of a band-like conductor, and reducing a burden of operation for preventing drop of the mounted winding. <P>SOLUTION: A secondary winding 30 is mounted by moving in an arrow B direction to insert a winding part 31 of a first turn and a winding part 42 of a second turn between a first spool part 11 and a second spool part 21. As the winding part 31 of the first turn and the winding part 42 of the second turn are inserted between the first spool part 11 and second spool part 21, tip end sides of the two winding parts are slightly opened. By further inserting, the winding part 31 of the first turn climbs over a retaining rib 16, and is fitted between a tip end side rib 14 and the retaining rib 16. In this state, a gap in a center of the winding part 31 of the first turn is fitted to the annular retaining rib 16, and thus, even when force for dropping the secondary winding 30 is applied, an inner circumferential surface 40 abuts on the retaining rib 16 to restrict movement. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
