    摘要： A deflection yoke device includes a deflection yoke for deflecting electron beams in horizontal and vertical directions, the electron beams being emitted from an electron gun of a color cathode ray tube; coma correcting coils positioned on an electron gun side of the deflection yoke so as to be opposed to each other in such a manner that the electron beams pass therebetween; and a pair of cores around which the coma correcting coils are wound, wherein a sliding mechanism is further provided for allowing each of the coma correcting coils to be slidable with respect to the corresponding core. Therefore, a misconvergence can be corrected by a simplified configuration without reducing a sensitivity of the coma correcting coils.

    摘要： An inline type color cathode-ray tube deflection yoke applies a deflecting magnetic field to electron beams from a neck portion of a valve accommodating three electron guns toward the funnel portion of the valve. The deflection yoke is provided with a vertical deflection coil, auxiliary coils serially connected to the vertical deflection coil, and a U-shaped magnetic member around each of both leg portions of which the auxiliary coils are wound. The U-shaped magnetic member is arranged so that the leg portions face the neck portion.
