ABSTRACT:
The vibrating gyroscope includes, for example, a regular triangular prism-shaped vibrating body. The vibrating body is formed with a material which generally generates mechanical vibration such as elinver, ceramics. The piezoelectric elements are respectively formed to the three sidefaces of the vibrating body. An oscillation circuit is connected between the two piezoelectric elements and the other piezoelectric element. Further, two U-shape supporting members made of metal wire are fixed to the ridge-line portions of the vicinity of the nodal points of the vibrating body. The both ends of the two supporting members are fixed to the rectangular-shaped supporting body. The supporting body has a cutting portion piercing through it from its one surface to the other or a groove portion as a suppressing means for suppressing the interference of vibrations between the fixing points of the ends of one supporting member and those of the other supporting member.
