Claims

[Scope of utility model registration request]

In a convergence device for a color cathode ray tube, in which a ring-shaped coil obtained by winding a required coil in a toroidal shape around a ring-shaped core is housed and fixed inside a morning glory-shaped holder, the ring-shaped core has the above-mentioned coils on both sides thereof. First and second ring-shaped coil bobbins provided with position regulating means for regulating the winding position of the coil are attached, and the peripheral surface of the ring-shaped core is covered with the first ring-shaped coil bobbin. A right-angled wall is formed and is fitted to the outer periphery of a right-angled wall provided on the first ring-shaped coil bobbin in succession to a position regulating means provided on the second ring-shaped coil bobbin. A convergence device for a color cathode ray tube, characterized in that protruding pieces are provided, and some or all of the protruding pieces are fitted and locked in a position regulating recess provided inside the holder.
