Summary:PROBLEM TO BE SOLVED: To solve the problem that, in a static induction electric instrument, a coiled spring and a winding press structure are large-sized because a wiring is needed to be maintained with predetermined wiring tightening force, and to endure electromagnetic force generated by a short-circuit current and an excitation inrush current. SOLUTION: A coiled spring 12, a nut 15, and a locking nut 16 are attached to a wiring press bolt 11, and the coiled spring 12 is compressed by turning the nut 15 and moving the nut 15 along the wiring press bolt 11. The wiring 7 is pressed with wiring tightening force in response to the amount of the compression, and, when the electromagnetic force is exerted in the opposite direction to the wiring tightening force, it is supported by a rigid section of the wiring press bolt 11. As a result, the coiled spring 12 and the wiring press structure can be miniaturized. COPYRIGHT: (C)2004,JPO&NCIPI
