Abstract

PURPOSE:To oscillator vibrator wihtout frequency variation by preventing a vibration from leaking externally, by providing a body different in acoustic impedance into-melting-point glass where a hermetic seal terminal holding a tuning-fork-shaped vibrator is buried. CONSTITUTION:A leaking vibration from vibrator 14 reaches protective cap 20 by way of a coupling part, hermetic seal terminal 18, low-melting-point glass 17, and metal ring 16, but since a body greately different in acoustic impedance in this route is made in order to mismatch impedance, part 22 where terminal 18 is buried in low- melting-point glass 17 is shaped in a spiral. Therefore, the length of the route of glass 17 where a vibration is transmitted toward metal ring 16 from terminal 18 varies with its direction and its leak vibration is canceled, so that a vibrator even when mounted will not have frequency vibration.
