GYROSCOPIC APPARATUS

PURPOSE:To enhance stability to the change in temp., by constituting a holder securing a torsion bar so as to make said holder movable to the radius direction and a direction of rotation with respect to a gimbal and providing an intermediate tap to the coil part of a variable detection apparatus. CONSTITUTION:A torsion bar 4 elastically restraining a gimbal 6 is fixed to the flange part 3b of a cylindrical holder 3. Next, a gap (g) is provided between the cylindrical part 3a of the holder 3 and the opening 2a of a housing 2 and the holder 3 is made freely movable to the radius direction and the direction of rotation with respect to the housing 2. Subsequently, an intermediate tap is provided to the primary and secondary coils 5c, 5d of the fixed part 5a of a deflection angle detection apparatus 5. By this constitution, even when there is the eccentricity of constitutional parts, the direction and quantity of the deflection of the deflection angle detection apparatus 5 are detected to correct said deflection and the generation of unbalance magnetic flux is prevented to prevent the generation of the non-uniform change in magnetic flux due to the change in temp. and a stable gyroscopic apparatus can be obtained.
