The coil spring comprises a plurality of wire coils that spirally extend at a generally constant pitch and include first and second end portions, with the end portions being tapered and disposed in the same plane as the last coil on each end of the coil spring. The overall shape of the coil spring when in a torsion and stress free state is generally trapezoidal. The second disc member is disposed on one or both sides of the first disc member and includes a portion which engages with the first and second end portions of the coil spring.
