8a and 8b indicate the deep portion, 9a and 9b indicate the shallow portion, and 2p indicates the offset distance between the centers of the bottoms of adjacent winding grooves. Figure 2 Figure 5 Figure 6

Claims (1)

[Claims for Utility Model Registration] Three or more flanges protrude from the outer periphery of the cylinder wall in the axial direction at a constant interval S, and a plurality of winding grooves for winding electric wires are provided between adjacent flanges. In the split-wound coil bobbin, the depth of the winding grooves from the outer edge of the collar is changed by shifting the bottom centers of the adjacent winding grooves to form a deep part and a shallow part. A split-wound coil bobbin characterized in that the phases of the deep part of one winding groove and the shallow part of the other winding groove are made to match each other.
