抄録

When a coiled spring whose both ends are kept parallel is gradually compressed, it generates a lateral deflection even before it is compressed to the critical load. This may result in undesired contact with other mechanical members. In this paper, compression tests were carried out and quantities of lateral deflection and shift of Tip-Contact Points (T.C.P.) were measured. It was made clear that the quantity of lateral deflection and shift of Tip-Contact Point caused by compression depend on the difference of spring indices. A model which illustrates this result successfully was introduced.
