DRIFT PREVENTION STRUCTURE FOR DEFLECTION YOKE

摘要

PURPOSE: A drift prevention structure is provided to achieve improved characteristics of screen by improving the shape of the plate for a magnet so as to reduce drifts on the screen. CONSTITUTION: A drift prevention structure comprises a magnet mounted on the front cover of the coil separator so as to prevent geometric distortions; and a plate(20) for a magnet interposed between the magnet and the front cover so as to prevent a reduction of magnetization of the magnet. The plate for the magnet has a length of 32mm or shorter.
