Claims

[Scope of utility model registration request]

A pair of substantially "king"-shaped cores are arranged in parallel, a pair of controlled coils are respectively wound in sections over the pair of cores, and a coil bobbin is wound so as to surround the outside of the pair of controlled coils. In the dynamic convergence correction device, a control coil is wound around the coil bobbin, and a magnet magnetized in the thickness direction is attached to the outer surface of the outer flanges of the pair of cores. A substantially “8”-shaped space is configured with enlarged portions provided outwardly at both ends, the pair of cores are housed within the space of the coil bobbin, and the magnet is housed within the enlarged portion of the coil bobbin. At the same time, each of the enlarged portions of the coil bobbin is provided with a cover having a pressing means that contacts the surface of the magnet on the inner surface, and an engaging claw that engages with a plate piece having external circuit connecting means on the outer periphery. A dynamic convergence correction device characterized by being fixedly attached.
