Abstract
An angular rate sensor detects an angular rate which is produced when a mobile body such as a motor vehicle moves. The angular rate detecting device comprises at least two angular rate sensors housed in a case perpendicularly to each other. The angular rate sensor comprising a pair of vibratory units which are interconnected by a connector in a tuning-fork configuration. The vibratory units of the angular rate sensors are vibrated at different frequencies. The angular rate sensors may be accommodated in a damper block, which may be housed in the case. Since the angular rate sensors are housed in the single case, the angular rate detecting device is compact in structure and small in size. With the angular rate sensors accommodated in the damper block, they are protected from resonance, crosstalk interferences, and noise, and hence can produce reliable detected output signals.
