Claims

[Scope of utility model registration request]

In a deflection yoke having a holder body for distortion correction disposed around a tube wall of an electromagnetic deflection type CRT display device, and a permanent magnet holding part for distortion correction at a corner portion provided in the holder body, the permanent magnet holding part is provided. The part includes a pair of elastic arc-shaped support pieces that are arranged to face each other so as to form a circular permanent magnet insertion area therebetween, and a pair of elastic support pieces that respectively connect both arc-shaped support pieces to the holder body. A deflection yoke characterized by:
