Title:
振動ジャイロ
Document Type and Number:
Japanese Patent JP6802125
Kind Code:
B2
Abstract:
A vibration gyroscope includes: a mass part supported to be displaceable in a first direction and a second direction; an exciter vibrating the mass part in the first direction; and a detector detecting a displacement amount of the mass part in the second direction. The first direction and the second direction are orthogonal to each other. A resonance frequency of the mass part in the first direction coincides with a resonance frequency of the mass part in the second direction. A Q-factor of vibration of the mass part in the second direction is smaller than a Q-factor of vibration of the mass part in the first direction.
