Abstract
A gyro apparatus includes a support in a base table for supporting one end of a vibrating member which has a circular cross-section and which is driven by a drive apparatus mounted on the base table to vibrate it in the longitudinal or axial direction. The vibrating member may be light conducting and a light source sends light through it which is projected onto a light detector so as to detect vibrations perpendicular to the axis direction of the vibrating member.
