PROBLEM TO BE SOLVED: To provide a piezoelectric vibrational gyro in which the supporting tool of a piezoelectric vibrator can be assembled easily and which is suitable for mass production, has dimensional accuracy which is not deteriorated even when the size of the gyro is reduced, and has stable characteristics. SOLUTION: A piezoelectric vibrational vibrator is constituted in such a way that the vibrational node or node line of a cylindrical piezoelectric vibrator which vibrates with one-wavelength resonance is stuck and fixed to a vibrator holder 15 through a supporting tool 12 made of a soft elastic material. The supporting tool 12 is composed of the soft elastic material having a through hole 13 of the same diameter as that of the vibrator at the center and has a fixing section 14 in the passing direction of the vibrator between the inside of the hole 13 to the outer edge of the tool 12. The fixing section 14 is stuck and fixed to the supporting section 16 of the holder 15. |
