A vibratory gyroscope for detecting a turning angular rate in a turning system is provided. The gyroscope comprises a vibrator, an exciting means for exciting driving vibration in the vibrator, and a detecting means for detecting vibration induced in the vibrator. The vibrator comprises a plurality of vibration systems 1A, 1B, 2A and 2B, which are formed within a specified plane intersecting the turning axis Z. Vibration systems comprises first vibration systems 1A and 1B whose vibrations include radial vibration components, in which the center of gravity of first vibration system vibrates in a radial direction in the specified plane with respect to the center of gravity GO of the vibrator. The vibration systems also comprises second vibration systems 2A and 2B whose vibrations include circumferential vibration components, in which the center of gravity of vibration of the second vibration system vibrates in the specified plane along a circle with the center of gravity GO as its center.
