Claims

[Scope of utility model registration request]

An engaging protrusion is provided on one side of the outer circumferential surface of the enlarged diameter portion of the head portion of the bobbin of the deflection yoke and the inner circumferential surface of the base ring that fits into the enlarged diameter portion of the head portion, and an engagement protrusion is provided on the other side of the outer circumferential surface of the enlarged diameter portion of the head portion of the bobbin of the deflection yoke. One or more engaging grooves that fit into each of the protrusions are provided, and when the deflection yoke and the base ring are aligned in the rotational direction by the engagement between the engagement protrusions and the engagement grooves, the top of the deflection yoke is A deflection yoke device, wherein a low frequency leakage magnetic field prevention coil is fixed to the base ring and arranged on at least one side of the side and the bottom side.
