Angular velocity sensor.

摘要

The present invention relates to an angular velocity sensor comprising a tuning fork vibrator which exerts tuning fork vibration by receiving a driving input and which generates a torque around the axis of a tuning fork owing to Coriolis force by undergoing a rotational action around the center of the tuning fork, and a detection torsional vibrator which exerts torsional vibration owing to the torque generated by the tuning fork vibrator, whereby the angular velocity sensor detects a rotational angular velocity around the axis of the tuning fork based upon the magnitude of the vibration of the detection torsional vibrator, said angular velocity sensor further comprising a buffer torsional vibrator provided at least singly outside said detection torsional vibrator for moderating external transmission energy loss of the torsional vibrator of said detection torsional vibrator. <IMAGE>
