Summary:A deflecting device for a cathode ray tube in which a plurality of winding slots are formed in the inner surface of a tubular core, in which slots deflecting coils are positioned, when THETA plane normal to the tube axis at the neck between a line connecting said tube axis to the centre of said winding slot in the transverse direction and a reference line in the horizontal direction, and THETA si is an angle in a plane normal to the tube axis at the screen between a line connecting said tube axis to the centre of said winding slot in the transverse direction and a reference line in the horizontal direction, said winding slots being formed to be THETA ni > THETA si in a first region of said tubular core, THETA ni = THETA si in a second region of said tubular core, and THETA ni < THETA si in a third region of said tubular core. o
