A sensitive element support for gyroscopic apparatus including an outer wheel connected to a drive shaft by flat transversely stiff elastic spokes having an effective plans parallel to the wheel, and an intermediate gimbal ring connected to the wheel by diametrically opposite flat, transversely stiff, torsional members having their flat plane normally perpendicular to the plane of the wheel, and connected to the shaft by similar members spaced 90 DEG away from the first torsinal members. Construction is simplified by making all connecting members in a single operation out of a flat sheet so as to leave the spokes and the other flat torsinal members between appropriate portions on which the outer wheel, gimbal ring and driving coupling will be attached. The torsinal members are then twisted to their final configurations, i.e., perpendicular to the sheet from which they were cut, and the flat sheet is sandwiched between two halves of the outer wheel, gimbal ring and hub portion. The completed assembly resembles a "cartridge" which, by its nature, has definite advantages in the initial fabrication and maintenance of the gyroscopic instruments using the "cartridge" to support the gyroscopic rotor.
