Abstract
A vibrating gyroscope includes supporting members which are fixed in the vicinity of two node axes n1 and n2 of a bar-shaped vibrator. The supporting members corresponding to node axis n1 extend from the locations at which they are fixed to the vibrator in the widthwise direction of the vibrator, and also include bending portions and a proximity portion. The bending portions bend toward node axis n1. At the proximity portion, the supporting members are in close proximity with each other with a gap therebetween in the vicinity of node axis n1.
Claims20
A vibrating gyroscope comprising:
- a bar-shaped vibrator for performing double-end-free bending vibration in a thickness direction thereof in response to receipt of a drive signal;
- and
- a pair of supporting members arranged to sandwich said vibrator in the vicinity of two node axes of said vibrator from both sides of said vibrator in the thickness direction thereof, said pair of supporting members being fixed to said vibrator;
- wherein said pair of supporting members extend from locations at which said supporting members are fixed to said vibrator in the widthwise direction of said vibrator, and include bending portions which bend toward each of the node axes, and a proximity portion at which said pair of supporting members are in close proximity with each other with a gap therebetween in the vicinity of the corresponding node axis.
