Claims

[Claims for Utility Model Registration] A bobbin having a front flange and a rear flange at both ends, a ferrite core provided on the outside of this bobbin, a vertical deflection coil wound around this ferrite core, and an inside of the bobbin. In a deflection yoke for an in-line color picture tube, the horizontal deflection coil is provided with a horizontal deflection coil wound in a saddle shape so as to form a window, and the horizontal deflection coil is partially wound in sections in the window. While being wound, this divided winding part is separated from the main part of the coil through a gap, and furthermore, the divided winding part has a bent part near the center of the length of the main part in the tube axis direction, and from this bent part The rear flange side extends substantially parallel to the tube axis and the vertical axis, and the front flange side extends away from the tube axis and the vertical axis from the bent part. Deflection yoke for pipes.
