Claims

[Scope of utility model registration request]

A horizontal deflection coil wound in a saddle shape, a coil bobbin with the horizontal deflection coil arranged on the inner surface, a core arranged on the outer surface of the coil bobbin, and a vertical deflection coil wound around the core in a toroidal shape or a saddle shape. a magnetic field receiving part that receives a vertical leakage magnetic field and is arranged near the front side of the core and the vertical deflection coil, and a magnetic field forming part that forms a correction magnetic field by the magnetic field received from the magnetic field receiving part. In a deflection yoke device configured to correct pink tension distortion using a magnetic field correction means,
A deflection yoke characterized in that a plurality of concave portions having open both sides are formed at intervals at positions interlinking with the horizontal leakage magnetic field generated from the horizontal deflection coil of at least the magnetic field forming portion of the magnetic field correction means.
