Patent ID: 8327706

Claim:
An angular rate detecting device comprising: a base layer; an interlayer provided on the base layer, a fixed part provided on the interlayer; a drive frame provided on a same layer as the fixed part, suspended from the fixed part via a first beam, a second beam, and a third beam, and suspended from the fixed part via a fourth beam, a fifth beam, and a sixth beam; a Coriolis frame provided on the same layer as the fixed part, and suspended from the fixed part via the drive frame and a seventh beam, wherein, when a direction on a surface of the base layer is taken as an x-axis direction and a direction perpendicular to the x-axis direction on the surface of the base layer is taken as a y-axis direction, the first beam, having one end connected to the fixed part and another end connected to the second beam, is extended in the y-axis direction, the second beam is extended in the x-axis direction, the third beam, having one end connected to the second beam and another end connected to the drive frame, is extended in the y-axis direction with a predetermined space from the first beam in the x-axis direction, the fourth beam, having one end connected to the fixed part and another end connected to the fifth beam, is extended in the y-axis direction, the fifth beam is extended in the x-axis direction, the sixth beam, having one end connected to the fifth beam and another end connected to the drive frame, is extended in the y-axis direction with the predetermined space from the fourth beam in the x-axis direction, and the second beam and the fifth beam are disposed to opposite sides of the fixed part in the y-axis direction.
