Abstract
PURPOSE:To obtain a titled spring that has large connecting strength between a substrate and fitting portions and high mechanical strength as a flat spring and is particularly suitable for a truck and a passenger car. CONSTITUTION:This flat spring in fiber reinforcing resin is provided with a lamimar substrate 4 in carbon fiber reinforcing epoxy resin, which has the desired curvature, and fitting portions 5, 6 in said epoxy resin, which both surfaces are attached to both ends in the longitudinal direction of the substrate 4. Connecting portions each consisting of wave forms, which mutually connnect as shown in the figure, are mounted to each connecting surface between the substrate 4 and the fitting portions 5, 6. Consequently, this device increases connecting area as compared to flat connecting surfaces as conventional flat springs while the connecting portions take partial charge of and are subject to shearing stress working to the connecting surfaces, thus remarkably improving connecting strength between the substrate and the fitting portions, then heightening mechanical strength as the flat spring.
