Abstract

A mechanism and method for supporting a tuning fork-type quartz crystal element which is arranged to fix the common connecting section of a pair of arms of the subject quartz crystal element having a substantially U-shape directly to a base member supporting the element by a particular adhesive agent having an acoustic impedance different from that of the quartz crystal element, thereby preventing a mechanical vibration energy from being transmitted during vibration of the quartz crystal element to the base member and supporting the quartz crystal element with the greatest possible stability and strength on the base member against external mechanical vibrations and shocks.
