DEFLECTION YOKE DEVICE

PROBLEM TO BE SOLVED: To provide a deflection yoke device whose consumption power is reduced, whose assemblability and productivity are improved, and whose manufacturing cost is reduced. SOLUTION: The deflection yoke device has a coil separator 33 molded of a resin and having a nearly circular cone shape, a horizontal reflection coil 30b installed along the inner surface of the coil separator, a magnetic core 34 disposed on the outer surface of the coil separator coaxially with the coil separator and having a nearly circular cone shape, and a vertical deflection coil 32b wound on the magnetic core. The magnetic core has a projection 38 projecting from its inner surface to the coil separator side. The coil separator has a notch 40 to accommodate the projection of the magnetic core and a cover 44 to cover the notch, and the cover is molded integrally with the coil separator.
