PURPOSE:To prevent deterioration due to time change at high temperature and vibration shock and to improve reliability by determining the motional characteristics around the input shaft of a gyroscope with hinge deflecting parts which are provided at the center of the plate part of a hinge in place of an ordinary elastic members. CONSTITUTION:A detecting hinge 30 having a second hinge 40 is fixed to a base stage 44 by using hinge attaching holes 40-2 at three hinge attaching parts 40-1 and by using bolt 50-4 and spacer 40-5. At this time, hinge deflecting parts 40-3 have the functions of plate springs. The deflecting parts have a free angular resonance frequency which is determined by inertial efficiency and the spring constant of the deflecting part 40-3 around a shaft that passes through the center O of the three attaching parts 40-1 and is perpendicular to the surface of a plate part 30-5 of the hinge. Thus the function of an elastic member is provided in the deflecting part. Even if this apparatus is used at high temperature, deterioration in characteristics due to time change, vibration and shock can be prevented, and the highly reliable gyroscope apparatus can be obtained. |
