PURPOSE:To improve the assembly operability by connecting a piezoelectric element to respective electrodes by utilizing support shafts for supporting a vibrator, and then connecting payoff end parts of the support shafts to a flexible printed board and connecting them directly to an external circuit. CONSTITUTION:A support shaft 3A supported pivotally on a vibration body 1 is inserted into the hole 2A' of the piezoelectric element 2A and adhered and fixed to the flank 1A of the vibration body 1 through an extremely thin adhesive layer to generate the state of electric coupling between the surface 1A of the vibration body 1 and piezoelectric element 2A. Further, the support shaft 3A and the opposite surface of the piezoelectric element 2A are made conductive and coupled by using a conductive adhesive 7A. Consequently, the electric coupling with the piezoelectric element is led out not through a lead wire. Support shafts 3B and 3D are exactly the same and three surfaces of a vibration gyro main body are completed. The support shaft 3C needs to be coupled electrically with the vibrator 1, so no insulating member is used and a fitting member 4C is pressed in the hole 1C' in the flank 1C of the vibrator 1 directly to generate an electric coupling state. |
