Abstract
Provided is a wheel suspension system (4) and a spring (6, 16, 26) therefor which can improve the ride comfort of the vehicle by reducing the sliding resistance between the cylinder and the piston of the tubular shock absorber (5) surrounded by the compression coil spring without increasing the size of the suspension system and without complicating the assembly work. The compression coil spring is adapted to produce lateral forces between two ends thereof as the compression coil spring is extended and compressed by forming the coil spring so as to have cyclically varying pitch angle for each turn of the coil wire.
