Tuning-fork vibratory gyro

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.
