Abstract
A vibratory gyroscope 10 includes a vibrator 12. The vibrator 12 includes a regular triangular prism-shaped vibrating body 14. On centers of the three side faces of the vibrating body 14, piezoelectric elements 16a, 16b and 16c are formed respectively. The vibrating body 14 is supported above a base plate 20 by supporting members. The vibrating body 14 vibrates vertically with no rotation. A case 22 is secured so as to cover the vibrating body 14. An upper portion 26 of the case 22 is so formed that its inner size in the direction of the width is shorter than a half-wave length of a sound wave of a vibrating frequency of the vibrating body 14.
