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 horizontal 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 side pink friction distortion using a magnetic field correction means, the magnetic field correction means has at least this magnetic field forming section at a position interlinking with the horizontal leakage magnetic field generated from the horizontal deflection coil of the magnetic field forming section. A deflection yoke device characterized by having a plurality of thin slits formed in substantially the same direction as the horizontal leakage magnetic field.
