<p>PURPOSE:To prevent lead wirings from floating by implanting conductor pins parallel to a central axis to projections having a stepwise difference from the end face perpendicular to the central axis of an insulating cylinder, connecting with radial grooves of the end face of the cylinder, and forming a groove which expands at the bottom in parallel with the central axis on the inner wall. CONSTITUTION:Pairs of conductor pins 21a, 21b-24a, 24b are projected from the outer periphery 25 of an insulating cylinder and implanted to the portions 26a- 26d having stepwise difference from the end face 27 of the insulating cylinder. Lead wiring guide grooves 28a-28d are radially provided on the end face 27 of the cylinder, and lead wiring guide grooves 31a-31d having expansions on the bottom for connecting with the grooves 28 are provided on the inner wall 29. Lead wirings 32 are disposed along the grooves 31a-31d, 28a-28d, and wound on pairs of pins 21a, 21b-24a, 24b. In this case, the expansions of the grooves 31a-31d prevent the wirings 32 from floating, thereby preventing the rotating core from contacting, thereby reducing the rate of malfunctions.</p> |
