Abstract
A deflecting yoke core with which magnetic saturation is prevented by optimizing the relationship between the core sectional area and the density of the magnetic flux distribution. The deflecting yoke core to be mounted between a neck and a funnel of a cathode ray tube has a hole extending from an opening end of a neck portion to an opening end of a funnel portion . The hole at the funnel portion widens toward the opening end of the funnel portion . An outer shape at the opening end of the funnel portion has a short diameter Dx along a minor axis X and a long diameter Dy along a major axis Y. Core sectional areas along a plane parallel to and passing through a core axis O are largest within an angular range of 30° to 65° measured around the core axis O from a 0° reference angle at the minor axis X.
