Abstract
A cathode-ray tube device including a deflection yoke for deflecting an electron beam emitted from an electron gun in horizontal and vertical directions. The deflection yoke has a vertical deflection coil that deflects the electron beam vertically. The vertical deflection coil is wound toroidally around a bell-shaped ferrite core, and on the electron gun side of the ferrite core, a square 'U' shaped magnetic body that is doubled back partway along in a longitudinal direction is disposed on the horizontal axis, so that the ends thereof extend towards and are separated along the tube axis.
