Abstract
PURPOSE:To reduce a fault which is not fail-safe, by providing a locating stopper for regulating so that one pair of plate spring-form conductive supporting terminals do not contact with each other in a state that the piezoelectric oscillator is not placed between. CONSTITUTION:Plural locating elastic thin pieces 13, 13' are projectingly provided in parallel and at regular intervals on one end of the supporting base 12. The piezoelectric oscillators (S1-S4, P1-P3) and the supporting terminal plate 2 are placed on the supporting bases 12, 12. The insulating plate 14 formed by insulating high molecular resin, etc. is inserted between the oscillators P1 and S2, between P2 and S3, and between P3 and S4. The displacement supply plate 15 is inserted between the supporting terminal plate and the wall surface having the input terminals T1, T2 and T3, T4 of the casing 11.
