Abstract
The invention relates to a support structure for a thickness-shear mode, convex lens type oscillator. The support structure contains an elastic ring made from an insulating material such as nylon. This ring is formed with a plurality of spaced, radially inwardly and integrally extending projections from the ring proper and said projections represent concentric recesses of opposite configurations one after another adapted for establishing pressure contact with the quartz crystal at their opposite surfaces and at different peripheral areas thereof.
