Abstract
The present invention realizes improved workability of electrical connection between an exciting coil and a circuit board disposed in a casing and ensures waterproofing of a connection portion. A waterproof case 25 in which a terminal bar 24 is buried is composed of a large-diameter portion 25a in a hollow bottomed-cylindrical shape and a small-diameter portion 25b around whose outer peripheral surface an O-ring 27 is fitted. A U-shaped end of the terminal bar 24 connected to an end of an exciting coil 7 is positioned in the hollow portion of the large-diameter portion 25a, part of a substantially linear portion extending from the U-shaped end of the terminal bar 24 is buried in the small-diameter portion 25b in an axial direction, and the other portion of the terminal bar 24 protrudes from the small-diameter portion 25b. An end of the other portion is soldered to a circuit board 4, and the small-diameter portion 25a of the waterproof case 25 is fittingly inserted in a cylindrical fitting portion 26 formed in the casing 1, whereby water-tightness is ensured.
