摘要: A vibratory gyro including a tuning-fork vibrator having a piezoelectric member and a supporting member supporting the tuning-fork vibrator. The tuning-fork vibrator has a driving-side vibration mode and a detection-side vibration mode. The tuning-fork vibrator resonates in the driving-side vibration mode, and the tuning-fork vibrator and the supporting member resonate as a whole in the detection-side vibration mode.

摘要: A vibratory gyro includes a tuning-fork vibrator having a piezoelectric member, and a supporting member supporting the tuning-fork vibrator. The tuning-fork vibrator has a driving-side vibration and a detection-side vibration. The turning-fork vibrator resonates in the driving-side vibration, and the turning-fork vibrator and the supporting member resonate as a whole in the detection-side vibration.

摘要: A tuning-fork vibration gyro includes a tuning-fork vibrator having two arms and a base portion, and a supporting portion located in a center of a rotational motion of the base portion caused by a vibration resulting from a Coriolis force. The supporting portion protrudes from two surfaces of the base portion opposite each other in a direction in which the vibration resulting from the Coriolis force occurs.
