Abstract: PROBLEM TO BE SOLVED: To enhance the S/N ratio of a detection signal, by a constitution wherein a plurality of vibration systems are provided and at least one among them is extended into a hollow region in a frame part. SOLUTION: A vibration system 1A, a vibration system 1B, a vibration system 2A and a vibration system 2B are installed inside a hollow region 8 in a frame part 10A for a vibrator. The respective vibration systems 1A to 2B protrude toward the inside of the hollow part 8 from the inside edge 10a of the frame part 10A. A vibrating body 3A in the first vibration system 1A and a vibrating body 3B in the first vibration system 1B are used as driving and vibrating bodies, and a vibration component 5A and a vibration component 5B in the radial direction are used as driving and vibration bodies. In this case, after they are turned, the Coriolis forces 7A act on the vibration systems 1A, 1B.  Accordingly, a vibration component 6A and a vibration component 6B in the circumferential direction are generated in a vibrating body 4A inside the second vibration system 2A and in a vibrating body 4B inside the second vibration system 2B. Vibrations of the vibration systems 2A, 2B, which are composed mainly of the vibration components 6A, 6B are detected, and a rotational angular velocity is computed on the basis of their detection values. Since the respective vibration systems 1A to 2B protrude from the frame part 10A, vibrations of the respective vibration systems 1A to 2B are separated effectively, and the S/N ratio of a detection signal is improved.
