Claims

[Claims for Utility Model Registration] An annular core disposed at the rear end of the deflection yoke and having a plurality of protrusions protruding inside the core, and a through hole having a diameter slightly larger than the protrusions; A convergence correction device comprising a correction coil formed by winding a winding around a coil bobbin into which the through hole is inserted, the coil bobbin having an elastic tongue protruding from the edge of the through hole and having a hook portion at the tip. and a rib parallel to the insertion direction of the coil bobbin is formed in the through hole, so that when the coil bobbin is inserted into the protrusion, the hook portion engages with the outer periphery of the core and the rib A convergence correction device whose tip is pressed against the protrusion.
