The securing can be achieved very easily, the separating member for securing the insulation is not required, the number of parts can be reduced, and the cost can be reduced. Further, since the twisted portion serves as positioning when the body is inserted and no impact is applied to the winding terminal, it is possible to prevent a connection failure or the like from occurring and to strengthen the lead wire tension. Furthermore, the tension can be strengthened and the insulation distance level can be easily adjusted by selecting the number of twists and the type of lead wire. In addition, when inserting the main body into the case, connect the lead wire and the winding terminal before forming the twisted part, or at the time of connection, make it easy to connect with the twisted part not disturbing the connection work. When the main body is inserted into the case, the main body can be easily inserted into the case while pulling the lead wire inserted through the wire insertion hole, and the twisted portion is automatically positioned immediately before the terminal by the insertion, which facilitates the assembly. Further, as compared with the case where a knot is formed on the twisted portion, the knot requires more labor to manufacture and is difficult to automate, but twisting is extremely easy and automation is easy. Further, in the case of a knot, it is almost difficult to automate the electrical connection of the lead wires, but in the case of a twisted portion, the automation is easy by twisting after the electrical connection. In addition, for ballasts, etc., it is necessary to make a specified connection by comparing each lead wire on the high-voltage side and the low-voltage side with the external lead wire for electrical characteristics inspection, but if the two wires are the same color, the polarity is specified if there is a knot While connection becomes extremely difficult,
Designated wiring is easy at the twisted portion.
