PURPOSE:To not only provide excellent assembly accuracy and deflecting efficiency but also remove negative anisotropic aberration, by basically applying constitution of saddle-saddle type and containing a toroidal winding part in a vertical deflecting winding. CONSTITUTION:A vertical deflecting winding 27 of saddle type comprises an upper half winding unit 27a and bottom half winding unit 27b, and the both units 27a, 27b occupy a symmetrical position with a horizontal plane H-H' as the reference. While a vertical deflecting winding 29 of saddle type consists of a right half winding unit 29a and left half winding unit 29b, and the both units 29a, 29b occupy a symmetrical position with a vertical plane V-V' as the reference. Another vertical deflecting winding 30 of toroidal type is arranged to the outside of the vertical deflecting winding. This winding 30 comprises an upper half winding unit 30a wound in a toroidal shape to an upper half part 31b of a core 31 of high magnetic permeability and a bottom half winding unit 30b wound in a toroidal shape to a bottom half part 31b of the core 31, and the both units 30a, 30b occupy a symmetrical position with the horizontal plane H-H' as the reference. |
