The dynamic force is transferred to horizontal dynamic force transfer axis by a direction change gear. As the horizontal dynamic force transfer axis rotates, horizontal axes rotate downward in sequence, and thus a triangular pillar plate is rotated by 120 degree. Thus, all of triangular pillar plates are rotated to complete one screen. Thus, a domino effect is obtained by changing the sequence of dynamic force transfer or the sequence of gears.

Abstract: PURPOSE: A deflection yoke is provided to achieve improved work ability and reliability by enhancing the strength of the terminal and preventing unwinding of the coil. CONSTITUTION: A deflection yoke comprises a terminal(10) having a main body wound with a coil(30) and bent into a cylindrical shape, and an edge where a plurality of holes are formed at a constant spacing so as to permit the coil to be inserted into the holes and prevented from being escaped from the terminal during winding of the coil.
