Abstract
A fixing device includes an auxiliary duct. The auxiliary duct is provided between a cover member attached to a coil bobbin so as to cover a magnetic core and a coil, and a core holder provided opposing to the coil bobbin, to which the magnetic core is attached. The auxiliary duct communicates with an intake hole provided at one end in a longitudinal direction of the cover member, and has opening holes overlapping with some of holder opening portions formed on the core holder. The fixing device causes air to flow into between the core holder and the coil bobbin via the auxiliary duct and the holder opening portions from the intake hole, and discharges the air warmed by heat of the coil from an exhaust hole formed at the other end of the cover member, thereby adjusting the flowing amount of air in a longitudinal direction of the coil.
