Vibratory gyroscope, vibrator used in this gyroscope, method for analyzing vibration of the vibrator, method for supporting the vibrator, and method for manufacturing the vibratory gyroscope

摘要

A vibratory gyroscope for detecting a turning angular rate of rotation applied to a vibrator in a predetermined temperature range is disclosed. The vibratory gyroscope has a vibrator, a supporting member for supporting the vibrator and an adhesive portion made of an adhesive provided between the supporting member and the vibrator for bonding the vibrator to the supporting member. The vibratory gyroscope detects a turning angular rate based on a detecting vibration excited in the vibrator according to rotation when a driving vibration is excited in the vibrator. The adhesive has a tan delta not higher than 0.1 within the temperature range.
