PURPOSE:To rationalize the relation between a detecting element and a stay, by installing a concave part, where an adapter plate part of the stay is inserted into, an and around a package forming cavity, and holing the adapter part with resiliency, in case of an ignition signal generating pulser. CONSTITUTION:In and around a cavity 16 being formed with a cope 12 and a drag 13, there is provided with a concave part 19 into which an adapter plate part 7a of a stay 7 is inserted, and a moving member 22 is set up in this concave part, while a slant face 22a is slidingly moved with clamping actuation, and this adapter plate part 7a of the stay 7 is held by a keep plate 20 by dint of energizing force of a spring 24. And, it is buried in resin to be injected to the inside of the cavity 16 from a gate 31 together with a magnet 2, a pole 3 and a signal generating coil 5 rolled on a bobbin 4, thus a package 6 is formed. Thus, the relation between the stay and the detecting element, namely, the relation between the detecting element of a pulser and a detected part is properly securable. |
