In this paper, the method of calculating the lateral deflection of coiled springs caused by parallel compression is reported. When coiled springs are compressed between parallel plates, they are eccentrically loaded. Lowery has given a solution of the lateral deflection of nonparallel compression. Kuhn reported the wobble behavior of the centrally loaded coiled springs. In this study, these two studies are combined by the model of the moving Tip-Contact Point accompanied with the compression. By using this model, the quantities of the lateral deflection can be calculated within not-too-large lateral deflections and compressions.
