Vibrating gyro element, support structure of vibrating gyro element, and gyro sensor

摘要

A vibrating gyro element includes in the same plane a base portion; a pair of vibrating arms for detection extended out of the base portion on both sides in a straight line shape; a pair of connecting arms extended-out from the base portion onto both sides in directions perpendicular to the vibrating arms for detection; a pair of vibrating arms for driving each extended-out from the tip portion of each of the connecting arms to both sides perpendicularly to this tip portion; two pairs of beams extended out of the base portion along the respective arms for detection; and a pair of support portions to which the respective beams extended out in the same direction are connected; wherein the support portion is arranged outside the vibrating arm for detection between the vibrating arms for driving in the extending-out direction of each of the vibrating arms for detection.
