Abstract
A device for measuring a physical value, such as a vibratory gyroscope, is provided. The device comprises a vibrator; a driving means for exciting a driving vibration in the vibrator; a detecting means for obtaining an output signal based on a detection vibration excited in the vibrator in response with the physical value; and a detection circuit for processing the output signal to provide a detection signal corresponding with the physical value. The vibrator has at least one bending vibration armsA andB vibrating in bending mode along a specified plane (X-Y plane). The bending vibration arm comprises at least a pair of base partsA,B and a connecting partconnecting the base partsA,B. The connecting and base parts define a pair of recessesA,B.
