まれている。DESCRIPTION OF EMBODIMENTS A convergence device according to an embodiment of the present invention will be described below with reference to FIGS. 2 to 4. 10 is a cylindrical holder made of elastic synthetic resin;
Several arcuate pieces 11 are provided on the upper part of the tube, and a tightening band 12 fitted onto the outer circumferential surface of the arcuate pieces 11 is tightened to attach it to the cathode ray tube. A plurality of arc-shaped fixing plates 13 projecting outward are integrally provided on the holder 10 at the bottom of the arc piece 11. A magnet mounting portion 14 is formed below this fixed plate 13. A plurality of wedge-shaped protrusions 15 are formed in the magnet mounting portion 14 in parallel to the axial direction, and a locking piece 17 is made elastic by a notch 16 at the lower end.
Several locking pieces 17 are provided with a retaining protrusion 18 at the lower end thereof. In this magnet mounting portion 14, a set of two ring-shaped six-pole magnets 19 and a ring-shaped spacer 22 are attached.
a, a set of two ring-shaped four-pole magnets 20;
A ring-shaped spacer 22b and a pair of ring-shaped lock magnets 21 are assembled in this order.
