められる。[Claims for Utility Model Registration] In a high-voltage bobbin for an ignition coil in which a high-voltage coil is formed by dividing a winding wire into a plurality of winding grooves, a notch for a crossover wire provided in a flange of the bobbin is provided in the flange. It has a shape formed by a straight line L□ placed at an appropriate position to ensure the strength of the outer periphery of and one or more tangents L3 that touch a curve L2 obtained from this straight line L1 by the following procedure. . (b) Any radius r (R2≧r≧R1)...where R1
, R2 are the inner diameter and outer diameter of the flange centering on point 0...
The radius r' is calculated using the following equation. r' −R1+α(r −R1)...where α is the number of spears (α≦1). (b) The straight line that passes through the intersection A of the circle with radius r' centered at point 0 and straight line L1 and touches the bottom surface of the winding groove (represented by a circle with radius R□ centered at point O) is point 0. Let B be a point that intersects a circle with a radius r centered at , then a curve L2 is obtained by connecting the points B obtained for all r in the range R2≧r≧R□.
