Abstract
A vibratory gyroscope including a vibrator () integrally having a plate-like body portion () spreading along a reference plane, three drive arms () extending in a first direction from the body portion along the reference plane, and two detection arms () extending in a second direction opposite to the first direction from the body portion along the reference plane. The three drive arms are composed of two exciting drive arms () that are excited in mutually opposite phases in the reference plane and a non-exciting drive arm () located between the two exciting drive arms. Each of the three drive arms has an arm width in a width direction along the reference plane and perpendicular to the first direction. Each of the two detection arms has an arm width greater than that of the drive arm in the width direction, thereby suppressing generation of vibrations along the reference plane.
