The first auxiliary metallic plate is positioned generally along a middle range of a longer section of the main metallic plate while the second auxiliary metallic plate is positioned to a side of the first auxiliary metallic plate with an appropriate spacing therebetween. The length of the first auxiliary metallic plate is larger than that of the second auxiliary metallic plate.
