Abstract

PURPOSE:To improve angular velocity detection accuracy by giving the same polarity to four driving piezoelectric elements provided to a vibrator and providing a support rod with detecting piezoelectric elements for detecting Corioli's force. CONSTITUTION:When AC voltages having the same polarity are applied to the four driving piezoelectric elements 5, the vibrator 2 vibrates in its breadthwise (arrow (a)) direction to deform by deflection in right-left and up-down symmetrical mode when an H shape is viewed from the front. When an angular velocity by rotation in a plane orthogonal to the cylinder center of a casing 4 is added to this vibration gyro 10, the vibrator 2 generates Corioli's forces in its thickness direction (arrow (b)) direction, but this forces are in mutually opposite directions between both breadthwise side parts of the H shape. Those mutually opposite Corioli's forces become a couple of forces rotating the vibrator 2 around a vertical axis to cause the support rod 3 to deform by deflection in a horizontal plane. The deflection deformation of this support rod 3 generates a voltage across each detecting piezoelectric element 6 and the Corioli's forces applied to the vibrators 2 are detected to calculated the angular velocity, angular velocity.
