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 toroidally around the core. , a magnetic field correction means having a magnetic field receiving part that receives a vertical leakage magnetic field, which is disposed 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 the deflection yoke device configured to correct side pink coupling distortion, a mounting tongue is provided in a substantially central portion of the magnetic field receiving portion of the magnetic field correcting means in a direction substantially perpendicular to the magnetic field receiving portion, and A accommodating portion for accommodating the mounting tongue is formed on the back surface of the enlarged front end portion, and at least two holes are provided on the back surface of the enlarged front end portion of the bobbin, and the holes are placed at positions corresponding to the holes of the magnetic field correction means. A deflection yoke device characterized by being provided with a recessed portion for fitting.
