This report deals with the damping factor of herical compression spring with a constant pitch and presents studies for the calculation of the additional stress on the spring at thee time of surging, which is often a main cause of failure of the spring. The results of our experiments reveal that damping effects come from three major frictions, internal and external frictions of the coil itself, the contact friction of the both ends of the spring, and the friction when coils are driven home. If the logarithmic damping factor derived form the linear theory is taken into account for the clarification of experimental results, and if we consider the ratio ξ between the amplitude of the mth harmonics Cm and the geometrical minimum coil clearance aT, the minimum damping factor is obtained as follows : ξmin≅0.015 whenζ≤0.003, ξmin≅1.6(ζ)0.8 whenζ≥0.003
