PURPOSE:To prevent the rupture of a vibrator and the peeling of the fixed portion due to environmental temperature change. CONSTITUTION:A pendulum 21, a frame 22 arranged around its outer periphery and a hinge 23 to connect these are integrally formed with the same material. A vibrator 15 has one end fixed to the pendulum 21 via a spacer 26 and the other end extended to the side of the frame 22, where the pendulum 21 is connected, and fixed to one end of a support 27 which is made of material with the thermal expansion coefficient almost equal to that of the vibrator 15. The support 27 has the other end fixed to both sides of the frame 22 at a position corresponding to one end of the vibrator 15. The expansion amounts of the vibrator 15 and the support 27 due to temperature change are almost equal and so thermal stress seldom occurs. |
