置。 In a deflection yoke mounted on a color cathode ray tube having an in-line electron gun, the deflection yoke is equipped with a toroidal type vertical deflection coil that generates a barrel type deflection magnetic field and a saddle type horizontal deflection coil that generates a pincushion type deflection magnetic field. At a position behind the vertical deflection coil when viewed from the screen side, a pair of symmetrical magnetic pieces are arranged so as to form a pair of gaps having different widths with respect to the horizontal scanning direction of the electron beam. A deflection device characterized by:
