Claims

[Scope of utility model registration request]

In a toroidal deflection yoke formed by combining a pair of toroidal core halves 1, 1 each having a vertical deflection coil wound thereon, the vertical deflection coil is formed by winding the core half 1 directly on the surface of the core half 1. Alternatively, it is composed of a base coil section consisting of a plurality of coil layers, and a main coil section consisting of a plurality of coil layers wound on the surface of the base coil section, and the outermost coil layer of the base coil section is: It is formed from a first winding 4 that is wound sparsely at intervals, and a second winding 5 that is densely wound between the first windings, and the second winding of the base coil section. The other windings have their winding centers at or near the core center on both end faces of the core halves, and the second winding of the base coil part.
The winding wire and the winding wire of the main coil portion have a winding center at a point closer to the core half side than the core center on the plane including the large diameter side end surface of the core half body, and have a winding center at a point closer to the core half side than the core center on the plane including the large diameter side end surface of the core half body. A toroidal deflection yoke characterized in that the winding center is located at a point farther away from the core half than the core center on the including surface.
