<p>PURPOSE:To accurately realize squareness of the four corners when a rectangular graphic is displayed by improving a convergence characteristic on an image screen of a cathode-ray tube. CONSTITUTION:A deflection yoke device is provided with a coil groove 1a and a shock absorbing part 9 having an angle (135 deg.) of an obtuse angle such as an angle (90 deg.) formed by the coil groove 1a formed in a connecting part of a bend-up regulating plate 7 and the bend-up regulating plate 7 is equally divided into three parts. Therefore, influence such as flexibility of an electric wire or winding time tension is reduced, and familiarity between a coil frame 4 and an electric wire can be improved, and an unbalance component of the magnetic field distribution generated by a coil is reduced, and a magnetic characteristic of a deflection coil is improved.</p> |
