Abstract:
A vibrating gyroscope comprising:a vibrator having first and second nodes of vibration, the vibrator including first and second piezoelectric substrates which are stacked with each other so as to define first and second principal surfaces of the vibrator which are parallel to each other, the first and second piezoelectric substrate being polarized in opposite direction of their thickness directions; andfirst, second, third and fourth support members each having an expanded portion and a pair of thin flexible portions which are bent in a z-shape and connected to the expanded portion,wherein the first and second support members are provided on the first and second principal surfaces of the vibrator, respectively such that the first and second support members sandwich the first node of the vibrator, the third and fourth members are provided on the first and second principal surfaces of the vibrator, respectively such that the first and second support members sandwich the second node of the vibrator, the thin flexible portions of the first and third support members being bent towards each other and the thin flexible portions of the second and fourth support members being bent away from each other.
