Vibrating gyroscope

A vibrating gyroscope comprising:

• a frame body including a first vibrating portion, a second vibrating portion, a first coupling portion, a second coupling portion, an opening portion, a first supporting portion, and a second supporting portion, the first and second vibrating portions being disposed parallel or substantially parallel to each other so as to be spaced apart from each other and extending in a first direction, the first and second coupling portions each coupling an end portion of the first vibrating portion and an end portion of the second vibrating portion to each other and extending in a second direction that is perpendicular or substantially perpendicular to the first direction, the opening portion being surrounded by the first and second vibrating portions and the first and second coupling portions, the first supporting portion extending towards the second coupling portion from the first coupling portion in the first direction, the second supporting portion extending towards the first coupling portion from the second coupling portion in the first direction;
• a first exciting member and a second exciting member, the first exciting member being provided on a surface of the first vibrating portion, the second exciting member being provided on a surface of the second vibrating portion, the first and second exciting members exciting the first and second vibrating portions, respectively;
• detection members provided on corresponding surfaces of the first and second vibrating portions, the detection members being arranged to detect vibration of the frame body;
• a first mass adding member and a second mass adding member provided at outer sides of the frame body, the first and second mass adding members being connected to the first and second vibrating portions, respectively;
• and
• a first connecting member and a second connecting member, the first connecting member connecting the first vibrating portion and the first mass adding member to each other, the second connecting member connecting the second vibrating portion and the second mass adding member to each other.
