Abstract
A gyro apparatus having a tuning fork and a detecting portion for detecting the moment generated by Coriolis force in the tuning fork is disclosed, in which the detecting portion is formed of a rectangular-shaped hinge, a base portion to which both ends of the rectangular-shaped hinge are fixed and a pair of detection piezo-electric elements fixed to the rectangular-shaped hinge spaced apart from each other in its up and down direction and in which the tuning fork is fixed to the central portion of the rectangular-shaped hinge between the pair of detection piezo-electric elements such that the tuning fork axis becomes substantially perpendicular to the longitudinal direction of the rectangular-shaped hinge portion and parallel to the plane of the rectangular-shaped hinge and the center of mass of the tuning fork coincides with the center of the rectangular-shaped hinge.
