Deflection yoke with inflexible holding part

1. Field of the Invention A deflection yoke for a cathode ray tube comprises a funnel shaped separator means having a cylindrical neck portion where a magnetic ring is attached. The magnetic ring is engaged with upward holding portions and with downward holding portions , which hold such magnetic ring. Root portions and of the downward holding portions and are substantially inflexible, where the inner circumference of the magnetic ring substantially contacts the root portions and , and the root portions and restrict the position of magnetic ring from being disengaged from the protrusions and when the downward holding portions and are forced to disengage the magnetic ring.
