Abstract
A piezoelectric vibrator 12 used for a vibrating gyroscope 10 includes a vibrating body 14 having, for example, regular triangular prism shape. Piezoelectric elements 14a, 14b and 14c are formed respectively on three side faces of the vibrating body 14. Supporting members 24a and 24b are attached to a ridge line of the vibrating body 14 in the vicinity of nodal points. The supporting members 24a and 24b are secured to two supporting substrates 26a and 26b. The supporting substrates 26a and 26b are attached to a base substrate 30 via buffer blocks 28a and 28b. The vibrating body 14 makes a bending vibration, and two ridge lines (A) at symmetrical portions against basic bending vibration are pressed, and the hardness of the two ridge line portions (A) is made high.
