Patent ID: 6879095

Claim:
A deflection yoke comprising: a pair of saddle-type horizontal deflecting coils located substantially symmetrically with respect to a central axis and having a substantially truncated pyramid shape; a magnetic core coaxial with the central axis, located on an outer peripheral side of the horizontal deflecting coils, and having a substantially truncated cone shape; and a pair of vertical deflecting coils, each having windings that are toroidally wound around the magnetic core, wherein for a position of a horizontal axis perpendicular to the central axis and a position of a vertical axis perpendicular to the central axis and the horizontal axis are given by 0°and 90°, respectively, along a circumferential direction around the central axis, the winding of one of the vertical deflecting coils has a starting point on the horizontal-axis side within a range of about 5°-30° and is distributed continuously or intermittently from the starting point to 90° so as to have a plurality of peak parts of a winding ratio in a winding distribution and is wound substantially symmetrically with respect to the vertical axis, and wherein the respective windings of the one vertical deflecting coil and the other vertical deflecting coil are wound substantially symmetrically with respect to the horizontal axis.
