<p>PURPOSE:To eliminate a part projected from the side of an earth terminal and simplify the connecting method of an earth wire and the earth terminal by providing a cylindrical part to the earth terminal, and providing a terminal mounting pin-part and a loop-hole in a yoke member. CONSTITUTION:With the shape of a pin-part 15f provided to a main member 15 of a yoke, the diameter phi d2 of the straight part 15f of root is larger than the inside diameter phi D1 of the cylindrical part of an earth terminal, the tip of the pin-part is tapered, and the diameter phid1 of the end part of the tip is designed to be smaller than the inside diameter phiD1 of the cylindrical part. Further, the inside diameter phiD3 of the loop hole 17a of a yoke supporting member 17 is about the same in size as the outside diameter phi D2 of the cylindrical part 25c of the earth terminal. Then, the cylindrical part 25c of the earth terminal is pressed from the loop hole side into a terminal mounting part of a yoke member 18. Thus, the cylindrical part 25c, according to the shape of the pin-part 15f, is slowly enlarged, and the inside face of the cylindrical part 25c is brought into metallic contact with the pin-part 15f, and thus body-earth to the yoke member 18 is performed.</p> |
