改善され、作業能率は一段と向上する。 First, a printed circuit board is formed into a disk shape having a pair of protrusions, and a hollow lid with a bottom corresponding to the printed circuit board is formed with a slit portion that engages with the disk-shaped locking protrusion. By assembling the printed circuit board parallel to the detection coil at a predetermined distance, the amount of space that the printed circuit board can accommodate in the case body can be minimized, thereby making it possible to significantly shorten the case body. Since positioning can be done extremely easily and accurately, assembly workability is improved and work efficiency is further improved.
