置。 In a deflection yoke device, in which a correction means including at least a magnetic material is attached to a coil bobbin constituting a deflection yoke, the coil bobbin corresponds to an extension line perpendicular to the tube axis from the attachment position of the correction means on the outer surface of the coil bobbin. A deflection yoke device characterized in that a thin plate portion having a reduced thickness is provided at a position where the correction means is partially fitted into the thin plate portion.
