Claims

[Scope of utility model registration request]

In a deflection yoke that has a holder part formed on the outer periphery of the neck part of a cathode ray tube, a mechanism part is formed for moving one of two permanent magnets arranged with the same pole facing each other to adjust the focus. A plurality of recesses are formed in the longitudinal direction, and the center hole of the moving permanent magnet can be slid on the outer periphery of the cylindrical part of the detent spacer that moves on the holder and has a protrusion that engages with the recesses. A deflection yoke characterized by holding.
