PROBLEM TO BE SOLVED: To reduce the temperature characteristic of a vibrational gyroscope by suppressing the fluctuation of the Q value of the detected vibration of a vibrator even when the ambient temperature of the gyroscope varies when the vibrator is stuck to supporting members. SOLUTION: A vibrational gyroscope is provided with a vibrator 30, supporting members 31, 31A, 31B, 32, and 33 which support the vibrator 30, and an adhesive section 20 which is interposed between the vibrator 30 and supporting members 31, 31A, 31B, 32, and 33 to stick the vibrator 30 to the members 31, 31A, 31B, 32, and 33. The rotational angular velocity of the vibrator 30 is found from the detected vibration of the vibrator excited in accordance with the rotational angular velocity when drive vibrations are given to the vibrator 30. The tan δ of the adhesive forming the adhesive section 20 is adjusted to <=0.1 in the working temperature range of the gyroscope. |
