<p>PROBLEM TO BE SOLVED: To provide a choke coil device which allows for reduction in the man-hours of assembling process.SOLUTION: A choke coil device includes a ring-shaped magnetic core 2, an insulation case 1 for housing the magnetic core 2, and a coil 3 wound around the magnetic core 2. The insulation case 1 includes a ring-shaped case body 11 covering the surface of the magnetic core 2, and a central ring 12 projecting from the inner peripheral surface of the case body 11 concentrically thereto, and an insertion space of the coil 3 is formed between the case body 11 and central ring 12. The insulation case 1 is provided, on the outer peripheral surface of the case body 11, with a first receiving piece 13 projecting therefrom and receiving the head side end 31 of the coil 3 and, on the outer peripheral surface of the central ring 12, with a second receiving piece 14 projecting therefrom and receiving the tail side end 32 of the coil 3.</p> |
