Technical Examples

A vibration-type angular velocity sensor realizing a suitably vibrating state of the vibrators by canceling the displacement of the vibrators caused by the gravity. The angular velocity sensor comprises base portions, vibrators coupled to the base portions, exciting means for driving and vibrating the vibrators in the x-direction, and detection means which, when an angular velocity is applied while the vibrators are being driven and vibrated, detects the angular velocity based on the vibrations of the vibrators in the y-direction at right angles with the x-direction, the angular velocity sensor further comprising position adjusting means for so adjusting the positions of the vibrators as to cancel the amount of displacement by which the vibrators are displaced by the gravity in the direction of the gravity.
