る。In addition, since the pressing pieces of the pressing ring are connected with spring properties and the pressing ring is formed into a substantially circular shape, it is not only possible to adjust the deflection yoke in the longitudinal direction and self-center it in the funnel-shaped portion of the cathode ray tube. Even if it is necessary to eccentrically adjust the deflection yoke with respect to the axis of the cathode ray tube, the deflection yoke can be adjusted using the spring properties of the connection part of the suppression piece, so the self-convergence type deflection yoke can be used. The practical effect as a mounting mechanism is a dog.
