<p>PROBLEM TO BE SOLVED: To assemble and fix a choke coil to a coil housing part of a case body simply and easily, without need of rubber attachment.SOLUTION: A choke coil 26 is formed of holder parts 36, erected in a flange shape, at three points of a core case 34, in which a core is housed, in a circumferential directions, and lead wires 40 wound round the holder parts 36. On each holder part 36, a fitting groove 38 is formed at the outer circumference. On a coil housing part 24 having an opening on the upper part of a case body 12, there is erected a coil fixation member 28 having three rib plates 30, disposed in a radial shape, each having a taper section with a thickness which increases from an upper end to a lower end. The fitting groove 38 of the holder part 36 which is formed on the core case 36 of the choke coil 26 is positioned in a manner to fit to the radial direction of the rib plates 30 of the coil fixation member 28, and inserted and tightly fixed into the rib plates 30 to have a stationary structure.</p> |
