Abstract
A suspension coil spring, when assembled to a suspension device, in which a spring reaction axis is positioned coincident with or sufficiently close to a load input axis, and the design and manufacture of coil springs are facilitated. Namely, A suspension coil spring () in a free state is formed so that a coil axis (AC) is bent in V-shape at bend point (PB) and the distance from the end turn center (CU) of the upper seating surface () to an imaginary coil axis (AI) is an upper inclination amount (V), and the distance from the end turn center (CL) to the imaginary coil axis (AI) is a lower inclination amount (V). When the suspension coil spring () is interposed between spring seats () in the suspension device and compress along a strut axis, the spring reaction axis of the suspension coil spring () is inclined and offset with respect to the imaginary coil axis (AI) according to the inclination amounts (V, V).
