７を嵌合した励磁コイル８とよりなる。(3) Embodiment In FIG. 1, a potted product 1 includes a bottomed aluminum alloy case 2 with an open end, and an electromagnetic component 3 as a potted member sealed in a lump of synthetic resin R inside the case 2. It becomes more. The electromagnetic part 3
consists of a yoke 4 having an L-shaped cross section with one piece superposed on the bottom inner surface of the case 2 and the other piece positioned outside the opening of the case 2; a magnet plate 5 superposed on one piece of the yoke 4; It consists of a magnetic pole 6 whose base end 6a is superimposed on the magnet plate 5 and whose tip of a rod portion 6b projects outside the opening of the case 2, and an excitation coil 8 with a bobbin 7 fitted into the rod portion 6b.
ケース２底部、ヨーク４および磁石板５にはね
じ挿通孔９1〜９3が穿設され、また磁極６の基端
部６ａにはねじ孔１０が形成される。 Screw insertion holes 9 1 to 9 3 are formed in the bottom of the case 2, the yoke 4, and the magnet plate 5, and a screw hole 10 is formed in the base end 6a of the magnetic pole 6.
