ABSTRACT:
A gyro-vibrator supporting mechanism for supporting a gyro-vibrator via a support section upon a substrate in a vibration unit in which a vibrator is installed, the gyro-vibrator having a drive section to which a Coriolis force is applied upon an angular rotation of the gyro-vibrator with the drive section vibrating in a first direction, the detection section vibrating in a second direction perpendicular to said first direction in response to said Coriolis force and in accordance with the magnitude of said Coriolis force for detecting the strength of the Coriolis force and said gyro-vibrator rotating about an axis in a third direction perpendicular to said first and second directions and including a support section for supporting said drive section and said detection section relative to the substrate, and wherein the supporting mechanism comprises a characteristic resonance frequency of vibration along at least one of the first and the second directions that is lower than a characteristic resonance frequency of vibration along a direction other than the at least one of the first and the second directions.
