Abstract
The present invention provides a vibration gyro having good detection sensitivity and good detection accuracy and which comprises four beams provided on a base portion and which are made substantially stationary, for any type of vibration used. Since the vibration stimulus and detection make use of the same vibration mode, and the beams is so configured that output signals output from the beams cancel noise output generated by externally applied vibration, it is possible that matching of the excitation to obtain a large output signal and the resonant frequency for detection can be achieved without placing great expectations on machining and assembly precision, and without affecting adversely to the performance thereof depending upon a supporting method.
