Claims

[Scope of utility model registration request]

This is a deflection yoke device in which a low-frequency leakage magnetic field prevention coil is attached to a deflection yoke, and the deflection yoke has a first engaging portion consisting of a rib for preventing hot melt flow on the head side of the bobbin, and a rib for preventing hot melt flow. At least one of the second engaging portions consisting of a rib other than the rib or an engaging hole is provided, and a first engaging portion for engaging with the first engaging portion is provided on the side of the leakage magnetic field prevention coil. A deflection yoke device provided with an engaging claw and a second engaging claw for engaging with the second engaging portion.
