ABSTRACT:
A vibrating gyroscope includes a bar-shaped vibrator and a support member. The bar-shaped vibrator includes a drive element for vibrating the bar-shaped vibrator and a detection element for detecting the vibration of the bar-shaped vibrator. The bar-shaped vibrator has two grooves therein which extend along a direction perpendicular to a longitudinal direction of the bar-shaped vibrator in the vicinity of two node points of the vibration of the bar-shaped vibrator, respectively. The support member has a shape in which two arch portions held in a non-horizontal direction are connected by two connecting portions at both ends of the arch portions. The arch portions of the support member are connected to the bar-shaped vibrator at respective bottoms of the grooves thereof.
