Abstract
A vibratory gyroscope includes a vibrator. The vibrator includes a triangular prism-shaped vibrating body. On three side faces of the vibrating body, piezoelectric elements are formed respectively. Supporting members are fixed to ridge-line portions in the vicinity of nodal points of the vibrating body. The supporting members are formed into a multi-layer structure. An elastic material having a large strength is used as inner portions of the supporting members, and a material having a good solderability is used as outer portions of the supporting members. Under the vibrator, a supporting plate is provided as a shield material. Furthermore, a work cover is provided on the side of and above the vibrator as a shield material. The supporting plate and the work cover are formed by a magnetic material such as iron, nickel, stainless steel or the like. In the vicinity of the supporting members, protective members are provided. In the outer vicinity of longitudinal opposite ends of the vibrator, protective members are provided.
