PROBLEM TO BE SOLVED: To provide a cathode-ray tube apparatus for improving the sensitivity of a VM coil by improving interference from an electron gun. SOLUTION: At a peripheral section wherein a funnel and a neck are connected, there are a first cylindrical holder wherein a magnet ring used for adjusting convergence and purity is provided at the outer periphery, and and a second cylindrical holder that has a speed modulation coil and is liberated along a tube axis to the first holder. Further, the first holder has an elastic section for energizing the second holder to the anode side along the tube axis. COPYRIGHT: (C)2005,JPO&NCIPI
