Abstract

PURPOSE:To keep the convergence unchanged inspite of controlling the left-right pin cushon strain greatly by applying a simple constitution in which only recesses is formed on the inside surface of a ring core. CONSTITUTION:A ring core of a deflecting coil is divided into plural parts, and a core member 3a constitutes a part of each divided part. A recess 8a on the necked side, and two recesses 8b on the aperture side are formed on the inside surface of the divided core member 3a. A wire 7 is wound around the core member 3a having these recesses 8a, 8b to form a troidal deflecting coil.
